Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat wire clips with good sturdiness, specifically to a heat wire clip with good sturdiness. Background Technology
[0002] Hot wire clamps are not only a bridge for electrical conduction, but also a key component that ensures stable current flow and a secure mechanical connection.
[0003] For example, a robust hot wire clamp with authorization announcement number "CN220672879U" uses a reinforcement mechanism to restrict the cable fixed by a hexagonal screw through the cooperation of a needle, fixing box, insertion rod, push plate, support plate, limit spring, and limit block. The needle and insertion rod, which are inserted into the lead wire at an angle, make it difficult for the lead wire to move when pulled downwards. The insertion rod needs to be completely broken to allow the lead wire to move, thus ensuring that the lead wire will not be easily pulled out of the hot wire clamp body. However, in the use of the hot wire clamp, the elastic component controls the clamp plate to fix the cable. If the elastic component is not stable enough, it will be compressed under pressure. At this time, gaps will appear in the clamp plate connected by the spring, causing the hot wire clamp to fail to hold the cable firmly, resulting in the cable being moved in position. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the hot wire clamp cannot hold the cable securely, causing the cable held by the hot wire clamp to shift position, and to propose a hot wire clamp with good stability.
[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a robust hot wire clamp, comprising a first clamping block and a curved block. The left side of the first clamping block is fixedly connected to the right side of the curved block. A clamping structure is connected to the top right side of the first clamping block. A straight plate is fixedly connected to the bottom right side of the first clamping block. A support structure is connected to the right side of the straight plate. A bracket is connected to the bottom left side of the first clamping block.
[0006] Preferably, the clamping structure includes a first screw and a ring. The outer wall of the first screw is threadedly connected to the top circular opening of the first clamping block. The bottom of the first screw is fixedly connected to the top of the ring. A nut is threadedly connected to the outer wall of the first screw. A washer is inserted into the outer wall of the first screw. A second clamping block is rotatably connected to the top of the outer wall of the first screw.
[0007] Preferably, the left side of the second clamping block is slidably connected to the groove on the outer wall of the first clamping block.
[0008] Preferably, the inner wall of the curved block is threaded with a second screw.
[0009] Preferably, the support structure includes a curved plate and a bent plate, the left side of the curved plate is fixedly connected to the right side of the straight plate, the inner wall of the curved plate is rotatably connected to the upper part of the outer wall of the bent plate, an arc plate is fixedly connected to the left side of the bent plate, and a bolt is threadedly connected to the top left side of the arc plate.
[0010] Preferably, the top left side of the arc plate is fitted with the bottom of the bracket, and the upper part of the outer wall of the bolt is threaded to the outer wall of the bracket.
[0011] The present invention provides a robust hot wire clamp with the following advantages: The clamping structure allows the nut to rotate downwards through the outer wall of the first screw, disengaging it from the surface of the washer. The washer then falls off the outer wall of the first screw. Next, the ring engages with the first screw, causing it to rotate upwards through the first clamping block. Since the left side of the second clamping block is slidably connected to the groove on the outer wall of the first clamping block, the upward rotation of the first screw moves the second clamping block upwards, causing its bottom to disengage from the top of the first clamping block. The cable is then passed between the second and first clamping blocks. The ring then engages with the first screw, causing it to rotate downwards, bringing the second clamping block downwards to engage with the top of the first clamping block, thus clamping the cable. The nut then rotates upwards through the outer wall of the first screw, moving the washer upwards until it abuts against the bottom of the first clamping block. At this point, the first clamping block, washer, and nut create friction reinforcement, preventing the first screw from rotating and increasing the cable's stability. This achieves a secure clamping of the cable, preventing any displacement of the cable. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5 In this embodiment, a robust hot wire clamp includes a first clamping block 1 and a curved block 5. The left side of the first clamping block 1 is fixedly connected to the right side of the curved block 5. The inner wall of the curved block 5 is machined with an internal threaded round opening. A clamping structure 2 is connected to the top right side of the first clamping block 1. A straight plate 4 is fixedly connected to the bottom right side of the first clamping block 1. A support structure 3 is connected to the right side of the straight plate 4. A bracket 7 is connected to the bottom left side of the first clamping block 1.
[0015] The clamping structure 2 includes a first screw 201 and a ring 202. The outer wall of the first screw 201 is threadedly connected to the top circular opening of the first clamping block 1. The first screw 201 rotates up and down through the inside of the top circular opening of the first clamping block 1 when subjected to force. The bottom of the first screw 201 is fixedly connected to the top of the ring 202, which facilitates the rotation of the first screw 201. A nut 203 is threadedly connected to the outer wall of the first screw 201. The nut 203 rotates up and down through the outer wall of the first screw 201 when subjected to force. A washer 204 is inserted into the outer wall of the first screw 201. The washer 204 is a thin steel sheet. A second clamping block 205 is rotatably connected to the top of the outer wall of the first screw 201. The top of the outer wall of the first screw 201 rotates with the bottom bearing of the second clamping block 205. The left side of the second clamping block 205 is slidably connected to the groove on the outer wall of the first clamping block 1 when subjected to force. The protrusion on the left side of the second clamping block 205 slides up and down through the inside of the groove on the outer wall of the first clamping block 1 when subjected to force. The clamping structure 2 causes the nut 203 to rotate downwards through the outer wall of the first screw 201, disengaging the nut 203 from the surface of the washer 204. At this point, the washer 204 falls off the outer wall of the first screw 201. Then, in conjunction with the ring 202, the first screw 201 rotates upwards through the first clamping block 1. Since the left side of the second clamping block 205 is slidably connected to the groove on the outer wall of the first clamping block 1, the upward rotation of the first screw 201 causes the second clamping block 205 to move upwards along with it, disengaging the bottom of the second clamping block 205 from the top of the first clamping block 1. Finally, the cable is passed through the second clamping block 205 and the first clamping block 1. Then, the ring 202 rotates the first screw 201 downwards, causing the second clamping block 205 to move downwards and fit against the top of the first clamping block 1, thus clamping the cable. Then, the nut 203 rotates upwards on the outer wall of the first screw 201, causing the nut 203 to move upwards along with the washer 204 until the washer 204 is pressed against the bottom of the first clamping block 1. At this time, the first clamping block 1, the washer 204 and the nut 203 form a friction reinforcement, preventing the first screw 201 from rotating, increasing the firmness of the cable fixation, realizing the hot wire clamp's stable clamping of the cable, and preventing the cable from shifting position.
[0016] The inner wall of the curved block 5 is threaded with a second screw 6, which can rotate back and forth on the inner wall of the curved block 5. The support structure 3 includes a curved plate 301 and a bent plate 302. The left side of the curved plate 301 is fixedly connected to the right side of the straight plate 4. The inner wall of the curved plate 301 is rotatably connected to the upper part of the outer wall of the bent plate 302. The bent plate 302 rotates under force through the pin on the inner wall of the curved plate 301. An arc plate 303 is fixedly connected to the left side of the bent plate 302. A bolt 304 is threadedly connected to the top left side of the arc plate 303. The top left side of the arc plate 303 is in contact with the bottom of the bracket 7. The upper part of the outer wall of the bolt 304 is threadedly connected to the outer wall of the bracket 7.
[0017] Working principle: Highly secure hot wire clips for cable clamping: The nut 203 is rotated downwards through the outer wall of the first screw 201, causing it to disengage from the surface of the washer 204. At this point, the washer 204 falls off the outer wall of the first screw 201. Then, in conjunction with the ring 202, the first screw 201 rotates upwards through the first clamping block 1. Since the left side of the second clamping block 205 is slidably connected to the groove on the outer wall of the first clamping block 1, the upward rotation of the first screw 201 causes the second clamping block 205 to move upwards along with it, causing the bottom of the second clamping block 205 to disengage from the top of the first clamping block 1. Finally, the cable is passed through the second clamping block. Between the second clamp 205 and the first clamping block 1, the cooperating ring 202 then rotates the first screw 201 downwards, causing the second clamping block 205 to move downwards and fit against the top of the first clamping block 1, thus clamping the cable. Then, the nut 203 rotates upwards on the outer wall of the first screw 201, causing the nut 203 to move upwards along with the washer 204 until the washer 204 is pressed against the bottom of the first clamping block 1. At this time, the first clamping block 1, the washer 204, and the nut 203 form a friction reinforcement, preventing the first screw 201 from rotating and increasing the firmness of the cable fixation.
[0018] Secure hot wire clamp installation: Make the rear of the curved block 5 fit against the surface of the column, and then rotate the second screw 6 backward through the curved block 5 via the protrusion on the surface of the second screw 6, so that the rear of the outer wall of the second screw 6 is connected to the round thread on the surface of the column, until the rear of the protrusion fits against the front of the curved block 5.
[0019] Highly secure hot wire clip branch suspension: Bolt 304 is rotated downwards through the left side of the outer wall of arc plate 303, causing the upper part of the outer wall of bolt 304 to disengage from bracket 7. Then, arc plate 303 is flipped downwards, causing bent plate 302 to rotate downwards through the pin shaft on the inner wall of curved plate 301. The branch line is then placed at the center of bent plate 302 and straight plate 4. Arc plate 303 is then flipped upwards, causing the left side of its outer wall to align with the bottom of bracket 7. Bolt 304 is then threaded into the inner wall of bracket 7 through the upward rotation of arc plate 303. Although this utility model has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
