In addition, in description of the present utility model, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating technical characteristic.Thus, be limited with " first ", " second " feature can express or implicit comprise one or more this feature, in the present description, the implication of " multiple " is two or more, unless otherwise expressly limited specifically.
As depicted in figs. 1 and 2, the fast demountable gauge head structure in the present embodiment, comprises gauge outfit main body 1, bottom 2, twist-lock circle 3, banking stop 4, appearance surface shell 5, first screw 6, second screw 7, stator 8 and table ear 9.
As shown in Figure 3, gauge outfit main body 1 is circular; The one side of gauge outfit main body 2 is provided with dial plate, and the one side relative with being provided with dial plate is provided with bottom 2, and stator 8 is located on the bottom 2 of gauge outfit main body 1; Particularly, stator 8 in the present embodiment is ring-type, the outer ledge of ring-type stator 8 is evenly provided with four latches 81, stator 8 is evenly provided with four screw holes, correspondingly, bottom 2 is evenly provided with four cylinder grooves, cylinder groove inwall is provided with internal thread, and stator 8 is located on the bottom 2 of gauge outfit main body 2 by above-mentioned screw hole, internal thread and the second screw 7 of matching with internal thread; The profile of stator 8 can be sheet or other shapes in other embodiments, originally can select according to the concrete structure of gauge outfit with becoming.
As shown in Figure 4, the twist-lock circle 3 in the present embodiment is ring-type, and the position that the inner side of twist-lock circle 3 is corresponding with the latch 81 of stator 8 is evenly provided with four open slots 31 matched with latch 81; Twist-lock circle 3 is located between bottom 2 and appearance surface shell 5.
As shown in Figure 5, the appearance surface shell 5 in the present embodiment is ring-type, and position corresponding with the latch 81 of stator 8 on appearance surface shell 5 is provided with four draw-in grooves 51 matched with latch 81; Twist-lock circle 3 is sheathed on the outward flange of appearance surface shell 5 rotationally, and now, the center line of the center line of gauge outfit main body 1, the center line of stator 8 and twist-lock circle 3 all overlaps with the center line of appearance surface shell 5; The outside of twist-lock circle 3 is provided with multiple moving tooth, and user makes twist-lock circle 3 rotate around the center line of appearance surface shell 5 by the moving tooth on twist-lock circle 3.
The fast demountable gauge head structure of the present embodiment also comprises four banking stops 4, and banking stop 4 is located on appearance surface shell 5; Particularly, each banking stop 4 is equipped with screw hole, appearance surface shell 5 is evenly provided with four cylinder grooves, the inwall of cylinder groove is provided with internal thread, and banking stop 4 is located at appearance surface shell 5 towards in the one side of gauge outfit main body 1 by above-mentioned screw hole, internal thread and the first screw 6 of matching with internal thread.
The inner side of twist-lock circle 3 is provided with the stopper slot 32 for being embedded banking stop 4, as shown in Figure 1, the one end being fixed at the banking stop 4 on appearance surface shell 5 embeds in the stopper slot 32 of twist-lock circle 3, thus limit twist-lock circle 32 and can only rotate around the center line of appearance surface shell 5, and other movement can not be done, the fault preventing twist-lock circle 3 off normal or deviate to cause from appearance surface shell 5.
The outer ledge of the ring-type appearance surface shell 5 in the present embodiment is also arranged with the table ear 9 be connected with watchband.
According to the difference of the turned position of twist-lock circle 3, the fast demountable gauge head structure of the present embodiment has the locking and unlocking two states.
By stirring the moving tooth on twist-lock circle 3 outer ledge, twist-lock circle 3 is rotated around the center line of appearance surface shell 5, due to the position-limiting action of banking stop 4, twist-lock circle 32 can only rotate around the center line of appearance surface shell 5, twist-lock circle 3 can not off normal or deviate from from appearance surface shell 5, avoid breaking down, when four open slots 31 on twist-lock circle 3 all align with the draw-in groove of four on appearance surface shell 5 51, four latches 81 being located at the stator 8 in gauge outfit main body 1 by the second screw 7 can be deviate from the draw-in groove of four appearance surface shell 5 51, now, the fast demountable gauge head structure of the present embodiment is in released state.
When four open slots 31 on twist-lock circle 3 all align with the draw-in groove of four on appearance surface shell 5 51, by stirring the moving tooth on twist-lock circle 3 outer ledge, twist-lock circle 3 is rotated around the center line of appearance surface shell 5, due to the position-limiting action of banking stop 4, twist-lock circle 32 can only rotate around the center line of appearance surface shell 5, twist-lock circle 3 can not off normal or deviate from from appearance surface shell 5, avoid breaking down, when twist-lock circle 3 around appearance surface shell 5 center line rotate and rotational angle be no more than 90 ° time, open slot 31 on twist-lock circle 3 staggers with the draw-in groove 51 on appearance surface shell 5, now four latches 81 of stator 8 are embedded in the gap between appearance surface shell 5 and twist-lock circle 3, this gap length is greater than the thickness of stator 8, now, the fast demountable gauge head structure of the present embodiment is in the lock state.
Latch 81 in the present embodiment, open slot 31, draw-in groove 51 quantity is four, when twist-lock circle 3 is no more than 90 ° around the angle that the center line of appearance surface shell 5 rotates, open slot 31 on twist-lock circle 3 staggers with the draw-in groove 51 on appearance surface shell 5, fast demountable gauge head structure is in the lock state, in other embodiments, latch 81, open slot 31, draw-in groove 51 quantity can be one, two, or three, latch 81 can be selected according to concrete structure and cost etc., open slot 31, the quantity of draw-in groove 51, the angle that twist-lock circle 3 rotates around the center line of appearance surface shell 5 looks latch 81, open slot 31, the quantity of draw-in groove 51 and distribution situation and determine.
Fast demountable gauge head structure of the present utility model only needs by rotating twist-lock circle 3, the open slot 31 on twist-lock circle 3 is made to stagger with the draw-in groove 51 on appearance surface shell 5 or align, thus fast the parts such as gauge outfit and watchband are installed or removed, realize fast assembling-disassembling and the independent assortment of the parts such as watchband and gauge outfit, and without the need to watchband is taken off from wrist in whole operating process, structure is simple, easy to use, meets consumer and realizes Individuality watch collocation requirement according to personal preference.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
