The disclosed airtightness detection device for a 90-degree tail wire camera of the utility model avoids air leakage during the airtightness detection process, effectively improves the stability of the device, and reduces the probability of false detection";

[0004] Same as most existing airtightness detection instruments, airtightness detection is carried out by pressurizing inside a mold matched with the camera to be detected. There are various types of existing cameras, including wireless, single-wire and double-wire cameras. When detecting different cameras, it is necessary to replace the mold, which is rather cumbersome and not convenient for detecting multiple types of cameras with a single mold. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vehicle-mounted camera testing device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a vehicle-mounted camera testing device includes an airtightness detection instrument 1, an upper mold 101 and a lower mold 102 disposed inside the airtightness detection instrument 1.

The blocking component 4 includes a sealing groove 401 penetrating through the hollow clamping block 202, and a plug plate 402 is slidably connected inside the sealing groove 401.

[0025] Specifically, place the camera in the space inside the lower mold 102 and the upper mold 101, pass the wire through the wire grooves inside the first clamping block 201 and the hollow clamping block 202, seal between the wire groove and the wire through the first sealing ring 3 and the second sealing ring 301, block and open the wire groove through the blocking component 4, and adjust the number of opened wire grooves to adapt to the placement of different numbers of wires.

[0026] Embodiment 1

[0027] As Figures 1 - 3 shown, in this embodiment, threaded holes 104 are symmetrically formed on one side surface of both the upper mold 101 and the lower mold 102. Connecting ears 203 are symmetrically and fixedly installed on both side surfaces of the first clamping block 201 and the hollow clamping block 202. A bolt 105 is movably disposed inside the connecting ear 203, and the bolt 105 penetrates through the connecting ear 203 and is screwed into the adjacent threaded hole 104; air grooves 204 are formed on the inner side surface of the wire grooves of the first clamping block 201 and the hollow clamping block 202. Clamping strips 207 are fixedly installed at both ends of the air groove 204 located inside the first clamping block 201. Clamping grooves 205 are formed on the inner side surface of the wire grooves of the first clamping block 201 and the hollow clamping block 202 on both sides of the air groove 204.

[0028] In this embodiment, by screwing the bolt 105 into the threaded hole 104, the first clamping block 201 and the hollow clamping block 202 are convenient to disassemble and install. The air groove 204 is communicated with the space inside the upper mold 101 and the lower mold 102 through air holes 208, so that the high-pressure gas inside the upper mold 101 and the lower mold 102 can enter the air groove 204 and push the first sealing ring 3 and the second sealing ring 301 to squeeze inward.

[0029] As Figures 3 - 5As shown, in this embodiment, extension strips 302 are fixedly installed on both end surfaces of the first sealing ring 3, connection grooves 303 are formed on both end surfaces of the second sealing ring 301, the extension strips 302 are movably inserted into the connection grooves 303, and grooves 304 are formed on the outer surfaces of the first sealing ring 3 and the second sealing ring 301; limiting rings 206 are fixedly installed on the inner surfaces of the wire grooves of the first clamping block 201 and the hollow clamping block 202, the first sealing ring 3 and the second sealing ring 301 are respectively movably engaged with the adjacent clamping grooves 205, and a plurality of air holes 208 are equiangularly formed on one side surface of the first clamping block 201, the hollow clamping block 202, the first sealing ring 3 and the second sealing ring 301.

[0030] During specific implementation, high-pressure gas pushes the first sealing ring 3 and the second sealing ring 301 to deform and squeeze the wire harness from the groove 304, so that the two can clamp the wire harness with a relatively small difference in diameter size. The insertion of the extension strip 302 and the connection groove 303 improves the sealing performance between the first sealing ring 3 and the second sealing ring 301. At the same time, through the engagement of the first sealing ring 3 and the second sealing ring 301 with the clamping groove 205, the two are convenient to disassemble and replace, so as to adapt to wires of different sizes. Thus, the clamping assembly 2 and the wire are sealed by the sealing ring, so that it can clamp and seal wires of different diameters, and prevent the mold from leaking air from this place.

[0031] Embodiment Two

[0032] On the basis of Embodiment One, in order to make up for the problem that the mold is not convenient to adapt to the camera detection of different numbers of wires.

[0033] As Figure 3 shown, in this embodiment, a lead screw 404 is rotatably connected inside the hollow clamping block 202, a nut 403 is screwed on the outer side of the lead screw 404, and one end of the nut 403 is fixedly connected to a plug plate 402; a motor 405 is fixedly installed on one side surface inside the hollow clamping block 202, and gears 406 are fixedly installed on the output end of the motor 405 and the outer surface of the lead screw 404, and the two gears 406 are movably engaged.

[0034] During specific implementation, the motor 405 operates to drive one gear 406 to rotate. Through the transmission of the two gears 406, the lead screw 404 rotates. Through the engagement of the lead screw 404 and the nut 403, and the sliding limit of the plug plate 402 and the sealing groove 401, the plug plate 402 slides inside the sealing groove 401 to block the wire grooves of the first clamping block 201 and the hollow clamping block 202, and adjust the number of wire grooves put into use. Thus, the wire grooves of the clamping assembly 2 are blocked and opened by the blocking assembly 4, so that the mold can be applied to the airtightness detection of wireless, single-wire and double-wire cameras, making the airtightness detection instrument 1 more convenient to use and increasing its practicality.
