In addition, in order to balance and enhance the grasping force of the clamping legs 50 and the lamp cup 30, four clamping legs 50 are provided, and the four clamping legs 50 are uniformly distributed along the circumferential direction of the damping ring 40. Meanwhile, four of the clamping pins 50 are provided with silica gel layers, and the silica gel layers are abutted to the lamp cup 30 to enhance the grabbing force. Meanwhile, the silica gel layer on the clamping pin 50 also plays a role in shock absorption.
It should also be mentioned that the shock absorbing ring 40 not only seals and prevents water from the edge of the flared end of the lamp cup 30 and the inner wall of the cylindrical shell 20, but also plays a shock absorbing role to protect the lamp cup 30. Meanwhile, the damping ring 40 is fixed to the inside of the lamp to fix the lamp cup 30, and the specific fixing manner is multiple, such as screw fixing.
As shown in fig. 2, the lamp housing 60 includes a transparent glass 61 and a sealing ring 62 disposed on the periphery of the transparent glass 61, wherein the sealing ring 62 may be a ring of silicone rubber surrounding the transparent glass 61. The lamp housing 60 is disposed at the flared end of the lamp cup 30, and the gasket 62 abuts against the damping ring 40. That is, the light in the lamp cup 30 can be transmitted through the transparent glass 61, and the sealing ring 62 is sealed by the damping ring 40. Meanwhile, the sealing ring 62 also plays a role in damping, so that the damage probability of the lamp cup 30 is reduced through double damping.

Specifically, the pressing ring 70 is preferably pressed against the seal ring 62 and then fixed by screws. Wherein the screws may simultaneously secure the pressure ring 70 to the lamp cup 30. Thus, the press ring 70 sandwiches the seal ring 62 and the damper ring 40 together between the press ring 70 and the lamp cup 30, thereby achieving sealing and preventing gas, water, or other substances from entering the lamp cup 30 and the cylindrical housing 20.
The utility model discloses technical scheme not only has realized the sealed and waterproof of lamp cup 30 flaring end edge and tube-shape casing 20 inner wall through the setting that adopts damping ring 40, can also play absorbing effect, protects lamp cup 30. Wherein, the damping ring 40 is also matched by the clamping foot 50 to enhance the fixing ability. Secondly, by the provision of the seal ring 62, secondary sealing is achieved to prevent gas, water or other substances from entering the lamp cup 30 and the cylindrical housing 20. Finally, the sealing ring 62 and the damping ring 40 are clamped between the pressure ring 70 and the lamp cup 30 by the arrangement of the pressure ring 70, so that the sealing effect is enhanced, and the probability of gas, water or other substances entering the lamp cup 30 and the cylindrical shell 20 is further reduced.
Referring to fig. 4, a light source is disposed in the lamp cup 30, a threading hole (not labeled) is formed through a sidewall of the lamp cup 30, and one of the connecting wires 16 electrically connected to the light source (disposed in the lamp cup 30) passes through the threading hole. Wherein, the connecting wire 16 is wrapped with a ceramic tube 11, and the ceramic tube 11 is located in the lamp cup 30 and is spaced close to the inner wall of the lamp cup 30.
It will be appreciated that the power supply line 17 is at a relatively high voltage during operation. If the connecting wire 16 is directly passed through the threading hole, the inner wall of the lamp cup 30 near the threading hole is electrically shocked during operation, thereby causing a shock pattern to appear on the surface or to be damaged. Therefore, by the arrangement of the ceramic tube 11, a creepage distance between the connection wire 16 and the lamp cup 30 is increased, thereby avoiding the occurrence of the above-described problems.
In another embodiment, referring to fig. 3, a fixing ring 12 is sleeved on the outer circumference of the tapered end of the lamp cup 30, and the connecting wire 16 is fixed by the fixing ring 12 after passing through the threading hole. It can be understood that the fixing strength of the connecting lead 16 is increased by the arrangement of the fixing ring 12, and the problem of thread falling or loosening is avoided.
In addition, the wire penetrating hole is coated with clay 13, and the clay 13 is adhered to the connecting wire 16. It will be appreciated that the addition of the clay 13 also enhances the holding strength of the connecting leads 16 and also acts as a seal.
In another embodiment, a cover 80 is disposed at the second port of the cylindrical housing 20, and a mounting plate is disposed in the cover 80 and is provided with a power supply. The power cord 17 of the power supply passes through the cylinder cover 80, and the power cord 17 of the power supply located in the cylinder cover 80 is locked by a lock catch.
It will be appreciated that the searchlight 10 may be carried by the power cord 17 providing electrical power as it is being moved or carried by the user, and thus is easily broken. Therefore, the power line 17 is reinforced and fixed by the lock catch, and the problem of being broken by pulling is avoided. In order to enhance the fatigue strength and tensile strength of the power line 17, a PE material is preferably used. Has the advantages of high strength, certain flexibility, difficult disconnection caused by pulling deformation and fracture and high temperature resistance.

Meanwhile, as can be seen from fig. 2, the cylindrical housing 20 and the cylindrical cover 80 form two accommodating spaces for respectively installing the lamp source and the power supply, and the installation mode reasonably utilizes the space and realizes the complementary interference of the two.
Further, it is easy to know that the temperature inside the cylindrical housing 20 is relatively high because the light-emitting source generates a large amount of heat during operation. Therefore, the power supply, the circuit board, and other components in the lid 80 are prevented from being affected by high-temperature conduction. Therefore, an isolation heat-resistant sheet 90 is installed between the cylindrical housing 20 and the cylindrical cover 80, and the surface of the isolation heat-resistant sheet 90 is preferably white or silver, because the light color is slow in heat conduction and the white and silver colors can reflect heat radiation to avoid the above problems, the specific structure is schematically shown in fig. 5.
Further, in order to facilitate the turning on and off of the power supply, referring to fig. 1 and 2, a switch 14 is disposed at an end of the cover 80, and the switch 14 is connected to the power supply, thereby controlling the power supply.
