Description

Technical Field

[0001] The present invention relates to the technical field of wire harness protection, and specifically relates to a waterproof, anti-retraction, shielding, heat-conducting and fixing device. Background Art

[0002] When powering an instrument, a power cord is required, and the power cord needs to pass through the instrument housing. In order to avoid wear at the contact position between the power cord and the housing, a fixing component is required for protection;

[0003] It is found that there is relative sliding between the existing fixing device and the wire harness during use. It not only has poor waterproof and anti-retraction capabilities, but also does not have the functions of grounding, shielding and heat conduction. Not only is the electromagnetic protection effect poor, but also the heat generated by the wire harness cannot be dissipated in time. Therefore, improvement is needed;

[0004] Therefore, it is necessary to invent a waterproof, anti-retraction, shielding, heat-conducting and fixing device. Summary of the Invention

[0005] Therefore, the present invention provides a waterproof, anti-retraction, shielding, heat-conducting and fixing device to solve the problems in the background art.

[0006] In order to achieve the above object, the present invention provides the following technical solution: A waterproof, anti-retraction, shielding, heat-conducting and fixing device, comprising:

[0007] A fixing cylinder, both sides of which are open;

[0008] A heat-conducting cylinder, which is fixedly connected inside the fixing cylinder. A metal ring is fixedly connected between the heat-conducting cylinder and one side of the fixing cylinder. A rubber ring is fixedly sleeved outside the fixing cylinder, and the metal ring is fixedly embedded inside the rubber ring;

[0009] A hollow cylinder, which is fixedly connected to one side of the metal ring. Four convex blocks are fixedly connected to the outside of the hollow cylinder and are evenly distributed in a circumferential shape.

[0010] Preferably, the heat-conducting cylinder is made of silica gel material.

[0011] Preferably, the convex blocks are made of rubber material.

[0012] Preferably, heat-conducting grooves are formed on the inner wall of the heat-conducting cylinder.

[0013] Preferably, the heat-conducting grooves are spiral.

[0014] Preferably, a push block is slidably sleeved outside the fixed cylinder. On the other side of the fixed cylinder, an adapter cylinder is fixedly connected. An air cushion is fixedly connected inside the adapter cylinder. The air cushion is annular. There are four auxiliary components evenly distributed in a circular shape on one side of the adapter cylinder. The auxiliary components are used to inflate the air cushion to make it bulge and increase the stability of the entire device.

[0015] Preferably, each auxiliary component includes a first cavity opened on the fixed cylinder. A first through groove is opened at the top of the first cavity. A box body is fixedly connected inside the first cavity. A second through groove is opened on one side of the box body. A piston is slidably arranged inside the box body of the first box body. One side of the piston is fixedly connected with a pull rod. The pull rod penetrates through the through groove and is in sliding contact with it. A moving plate is slidably arranged inside the first cavity. The moving plate penetrates through the first through groove and is fixedly connected with the push block. The moving plate is in sliding contact with the first through groove.

[0016] Preferably, a first spring is sleeved outside the pull rod. Two ends of the first spring are respectively fixedly connected with the piston and the inner wall of one side of the box body. A first pipeline is fixedly embedded at the bottom of the box body. The first pipeline extends into the air cushion inside it and is fixedly connected with the air cushion. The first pipeline is embedded on the adapter cylinder and the fixed cylinder and is fixedly connected with them. The first pipeline penetrates through the moving plate and is in sliding contact with it.

[0017] Preferably, each auxiliary component further includes a second cavity opened on the hollow cylinder. A clamping block is slidably arranged inside the second cavity. A fixing plate is fixedly connected inside the second cavity. A through hole is opened on the fixing plate. A second spring is fixedly connected between the clamping block and the fixing plate.

[0018] Preferably, a sleeve is arranged inside the second cavity. One end of the sleeve extends into the first cavity. The sleeve is embedded on the hollow cylinder, the metal ring and the fixed cylinder and is fixedly connected with them. A rope is fixedly connected between the clamping block and the moving plate. The rope penetrates through the second spring, the through hole and the sleeve. A sliding block is fixedly connected to the bottom of the fixing plate. The sliding block is in sliding contact with the rope.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. By designing the metal ring, when in use, the metal ring contacts the instrument shell and the wire harness, so that the effect of grounding and shielding can be achieved, and the electromagnetic protection effect is good. In addition, a heat conduction cylinder made of silicone material is designed. When in use, the heat conduction cylinder will wrap around the outside of the wire harness. Since the silicone material has a large friction force, the stability with the wire harness is good, and there will be no relative sliding phenomenon, thus ensuring the waterproof and anti-retreat effects. Moreover, silicone has a heat conduction effect, so the heat generated by the wire harness during use can be transferred to the metal ring, and then the metal ring transfers it to the shell, thereby achieving a heat dissipation effect and avoiding the wire harness from overheating at high temperatures;

[0021] 2. The present invention designs heat-conducting grooves on the inner wall of the heat-conducting cylinder, so that heat can be transferred not only by the silicone itself but also through the heat-conducting grooves, thereby increasing the heat dissipation effect during heat dissipation.

Detailed implementation manners

[0032] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0033] Embodiment 1, referring to the attached Figure 1 - attached Figure 2 , a waterproof, anti-retreat, shielding and heat-conducting fixing device provided by the present invention includes:

[0034] Fixed cylinder 1, both sides of the fixed cylinder 1 are open;

[0035] Heat-conducting cylinder 2, which is fixedly connected inside the fixed cylinder 1. A metal ring 3 is fixedly connected between the heat-conducting cylinder 2 and one side of the fixed cylinder 1. A rubber ring 4 is fixedly sleeved outside the fixed cylinder 1, and the metal ring 3 is fixedly embedded inside the rubber ring 4;

[0036] Hollow cylinder 5, which is fixedly connected to one side of the metal ring 3. Four bumps 6 are fixedly connected to the outside of the hollow cylinder 5 and are evenly distributed in a circumferential shape;

[0037] The heat-conducting cylinder 2 is made of silica gel material, and the bumps 6 are made of rubber material

[0038] In this embodiment, the metal ring 3 is designed. When in use, the metal ring 3 contacts the instrument shell and the wire harness, so that the effect of grounding shielding can be achieved, and the electromagnetic protection effect is good. In addition, the heat-conducting cylinder 2 made of silica gel material is designed. When in use, the heat-conducting cylinder 2 will wrap around the outside of the wire harness. Since the silica gel material has a large friction force, the stability with the wire harness is good, and there will be no relative sliding phenomenon, thus ensuring the waterproof and anti-retreat effects. Moreover, silica gel has a heat-conducting effect, so the heat generated by the use of the wire harness can be transferred to the metal ring 3, and then the metal ring 3 transfers it to the shell, thereby achieving the heat dissipation effect;

[0039] Among them, in order to achieve the purpose of increasing the heat-conducting effect, the following technical solution is adopted in this device: a heat-conducting groove 7 is opened on the inner wall of the heat-conducting cylinder 2, and the heat-conducting groove 7 is spiral, and the heat-conducting groove 7 can increase the heat-conducting effect.

[0040] The usage process of the present invention is as follows: When in use, pass the wire harness through the heat-conducting cylinder 2, the metal ring 3, and the hollow cylinder 5, and then align the hollow cylinder 5 with the slot on the instrument housing and insert it until the metal ring 3 and the rubber ring 4 contact the outer side of the instrument housing. Since the bump 6 is made of rubber material and has toughness, the bump 6 can pass through the slot on the housing and contact the inner wall of the housing, so that the device can be stuck on the housing. Since the metal ring 3 is designed on the fixing device, when in use, the metal ring 3 contacts the instrument housing and the wire tying part of the wire harness, so that the effect of grounding shielding can be achieved, and the electromagnetic protection effect is good. In addition, a heat-conducting cylinder 2 made of silicone material is designed. When in use, the heat-conducting cylinder 2 will wrap around the outside of the wire harness. Since the silicone material has a large friction force, the stability with the wire harness is good, and there will be no relative sliding phenomenon, thus ensuring the waterproof and anti-retreat effects. Moreover, silicone has a heat-conducting effect, so the heat generated by the wire harness during use can be transferred to the metal ring 3, and then the metal ring 3 transfers it to the housing, thereby achieving a heat dissipation effect and avoiding overheating of the wire harness due to high temperature. In addition, heat-conducting grooves 7 are designed on the inner wall of the heat-conducting cylinder 2, so that the heat can be transferred not only by the silicone itself but also through the heat-conducting grooves 7, and the heat can be quickly transferred to the metal ring 3, so that the heat dissipation effect can be increased during heat dissipation.

[0041] Example 2. Refer to the attached Figure 3 - attached Figure 7 , which is different from Example 1 in that:

[0042] A push block 8 is slidably sleeved outside the fixed cylinder 1. On the other side of the fixed cylinder 1, an adapter cylinder 9 is fixedly connected. An air cushion 10 is fixedly connected inside the adapter cylinder 9. The air cushion 10 is annular. On one side of the adapter cylinder 9, four auxiliary components are arranged in a circumferentially uniform distribution. The auxiliary components are used to inflate the air cushion 10 to make it bulge and increase the stability of the whole device.

[0043] The auxiliary component includes a cavity one 11, which is opened on the fixed cylinder 1. A through groove one 12 is opened at the top of the cavity one 11. A box body 13 is fixedly connected inside the cavity one 11. A through groove two is opened on one side of the box body 13. A piston 14 is slidably arranged inside the box body 13. A pull rod 15 is fixedly connected to one side of the piston 14. The pull rod 15 penetrates through the through groove and is in sliding contact with it. A moving plate 16 is slidably arranged inside the cavity one 11. The moving plate 16 penetrates through the through groove one 12 and is fixedly connected to the push block 8. The moving plate 16 is in sliding contact with the through groove one 12.

[0044] A first spring 17 is sleeved outside the pull rod 15. Two ends of the first spring 17 are respectively fixedly connected to the piston 14 and an inner wall on one side of the box body 13. A first pipeline 18 is fixedly embedded at the bottom of the box body 13. The first pipeline 18 extends into the air cushion 10 inside and is fixedly connected to the air cushion 10. The first pipeline 18 is embedded in and fixedly connected to the connecting cylinder 9 and the fixed cylinder 1. The first pipeline 18 penetrates through the moving plate 16 and is in sliding contact with it.

[0045] The auxiliary assembly further includes a second cavity 19. The second cavity 19 is formed in the hollow cylinder 5. A clamping block 20 is slidably arranged inside the second cavity 19. A fixing plate 21 is fixedly connected inside the second cavity 19. A through hole 26 is formed in the fixing plate 21. A second spring 22 is fixedly connected between the clamping block 20 and the fixing plate 21.

[0046] A sleeve 23 is arranged inside the second cavity 19. One end of the sleeve 23 extends into the first cavity 11. The sleeve 23 is embedded in and fixedly connected to the hollow cylinder 5, the metal ring 3 and the fixed cylinder 1. A rope 24 is fixedly connected between the clamping block 20 and the moving plate 16. The rope 24 penetrates through the second spring 22, the through hole 26 and the sleeve 23. A sliding block 25 is fixedly connected to the bottom of the fixing plate 21. The sliding block 25 is in sliding contact with the rope 24.

[0047] The using process of the present invention is as follows: When passing the wire harness through the heat conducting cylinder 2, the metal ring 3 and the hollow cylinder 5, first push the push block 8 to the right. In this way, the moving plate 16 can be moved to the right. The moving plate 16 moving to the right drives the pull rod 15 and the piston 14 to move to the right. In this way, the first spring 17 can be compressed. At the same time, under the action of the first pipeline 18, when the piston 14 moves to the right, the air in the air cushion 10 can enter the box body 13. In this way, the air cushion 10 will become deflated. Among them, when the moving plate 16 moves to the right, it can also pull the rope 24. In this way, the clamping block 20 can be moved into the second cavity 19. At the same time, the second spring 22 is compressed. In this way, when passing the wire harness through the heat conducting cylinder 2, the metal ring 3 and the hollow cylinder 5, the air cushion 10 can smoothly pass through the air cushion 10. Then align the hollow cylinder 5 with the slot on the instrument housing and insert it until the metal ring 3 and the rubber ring 4 contact the outside of the instrument housing, and the convex block 6 contacts the inner wall of the housing. In this way, the device can be clamped on the housing. Then push the push block 8 to the left. At the same time, under the action of the first spring 17 rebounding, the air in the box body 13 enters the air cushion 10. In this way, the air cushion 10 will become inflated and then closely fit outside the wire harness. In this way, the waterproof ability and anti-retreat ability of the device can be qualitatively improved. Among them, when the second spring 22 rebounds, the clamping block 20 can move out of the second cavity 19. In this way, the clamping block 20 can contact the inner wall of the housing. In this way, the stability between the device and the housing can be increased. In this way, the device will not easily fall off the instrument housing.

[0048] The above are only the preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection required by the present invention.
