Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of power engineering technology, and more specifically, to a highly stable power fitting clamp. Background Technology

[0002] Power fittings are devices used in overhead power lines and distribution equipment to support, fix, and connect bare conductors, conductors, and insulators into strings. They are also used to protect conductors and insulators. Power fitting clamps are clamps used to forcefully fix cables and connect them to insulators.

[0003] A search revealed that utility model patent CN219960065U discloses a power fitting clamp designed to prevent loosening. The clamp is secured to the cable by a toothed plate at the bottom of the connector and an external thread on the outside of the fastening bolt that matches the internal thread of the threaded pipe. A limiting pin is inserted through the two connecting lugs for stable installation.

[0004] In the aforementioned patent, when dealing with cables of different sizes, there is no way to adjust the connection according to the cable size, which easily exposes the connection and leads to poor connection. At the same time, when dealing with larger cables, the bolt tightening is not sufficient, which makes the bolts easy to loosen and cause the cable to fall off. Utility Model Content

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-7 As shown, this illustration depicts a highly stable power fitting clamp according to an embodiment of the present disclosure. It includes a fixed frame 1, a drive assembly 2 and a transmission assembly 3 mounted at the center of the top of the fixed frame 1, a locking assembly 6 mounted on the right side of the top of the fixed frame 1, a control assembly 4 mounted inside the fixed frame 1, a fixing assembly 5 mounted on the front of the fixed frame 1, a movable cavity 101 formed inside the fixed frame 1, and an annular groove 102 formed around the inner wall of the movable cavity 101. The control assembly 4 includes a control frame 401 movably fitted inside the movable cavity 101, teeth 403 fixedly connected to the center of the outer surface of the control frame 401, and teeth 403 fixedly connected to the front of the control frame 401. The frame has an arc-shaped groove 402 around its perimeter. The fixing component 5 includes an annular frame 501 fixedly connected to the front of the fixing frame 1. Clamping rods 502 are slidably sleeved around the annular frame 501. Clamping blocks 503 are fixedly connected to the close ends of the clamping rods 502. A fixing rod 505 is fixedly connected to the back of the clamping rods 502. The fixing rod 505 is adapted to the arc-shaped groove 402. The driving component 2 includes a support block 201 fixedly connected to the top of the fixing frame 1. A worm gear 202 is movably sleeved on the inner side of the support block 201. A fixing plate 203 is fixedly connected to the right side of the worm gear 202. A handle 204 is fixedly connected to the right side of the fixing plate 203.

[0035] In this embodiment, after the cable is passed through the middle of the control frame 401, the fixed disk 203 is rotated by the handle 204, thereby driving the worm gear 202 to rotate. The meshing of the worm gear 202 and the worm wheel 303 drives the cylindrical rod 302 to rotate, which in turn drives the cylindrical gear 304 to rotate. Under the meshing of the cylindrical gear 304 and the teeth 403, the control frame 401 rotates clockwise. Under the cooperation of the arc groove 402 and the fixed rod 505, the clamping rod 502 moves closer to the clamping rod. The cable is clamped and fixed by the movement of the inner liner 504, which increases the friction with the cable surface, making the clamping more stable. Due to the self-locking principle of the worm gear 303 and worm 202, the cylindrical gear 304 is prevented from rotating, thereby preventing the control frame 401 from rotating. At the same time, under the elastic force of the spring 601, the locking rod 602 is inserted into the inner side of the corresponding fixing groove 205, which can further position the fixing plate 203 and prevent the fixing plate 203 from driving the worm 202 to rotate under the action of external force.

[0036] In some examples, a positioning ring 404 is fixedly connected around the control frame 401, and the positioning ring 404 is movably sleeved with the annular groove 102.

[0037] The positioning ring 404 and the annular groove 102 work together to position the control frame 401, preventing the control frame 401 from falling off the inside of the movable cavity 101 or shifting.

[0038] In some examples, the arcuate surface of the positioning ring 404 is movably fitted with a roller 405, which contacts the inner wall of the annular groove 102.

[0039] When the control frame 401 rotates, the roller 405 rolls against the inner wall of the annular groove 102, resulting in low friction and preventing interference or jamming of the control frame 401 during rotation.

[0040] In some examples, the surface of the clamping block 503 is fixedly connected with an inner liner 504, which is made of rubber. The inner liner 504 can increase the contact area with the outer surface of the cable and increase the friction during clamping and fixing.

[0041] In some examples, the locking assembly 6 includes a cylindrical groove 103 formed on the top of the fixed frame 1. A spring 601 is fixedly connected to the inner side of the cylindrical groove 103. A locking rod 602 is fixedly connected to the top of the spring 601. A control block 603 is fixedly connected to the outer side of the locking rod 602. A fixing groove 205 is formed around the fixed plate 203. The fixing groove 205 is adapted to the locking rod 602. The locking rod 602 is movably sleeved with the cylindrical groove 103. The top edge of the locking rod 602 is chamfered.

[0042] When it is necessary to control the drive component 2, the locking lever 602 is pressed down by the control block 603, thereby separating the locking lever 602 from the inside of the fixing groove 205. The design of the chamfered top of the locking lever 602 makes it easier to insert the locking lever 602 into the inside of the fixing groove 205.

[0043] In some examples, the transmission assembly 3 includes a support plate 301 fixedly connected to the top of the fixed frame 1. A cylindrical rod 302 is movably sleeved on the inner side of the support plate 301. A worm gear 303 is fixedly sleeved on the back side of the outer side of the cylindrical rod 302. A cylindrical gear 304 is fixedly sleeved on the front side of the outer side of the cylindrical rod 302. The worm gear 303 meshes with the worm 202, and the cylindrical gear 304 meshes with the teeth 403.

[0044] When the worm 202 rotates, it drives the worm wheel 303 to rotate, which in turn drives the cylindrical rod 302 to rotate the cylindrical gear 304. Through the meshing action of the cylindrical gear 304 and the teeth 403, the control frame 401 rotates. When the control frame 401 rotates clockwise, the clamping rods 502 move towards each other. When the control frame 401 rotates counterclockwise, the clamping rods 502 move away from each other.

[0045] Working principle and usage process of this utility model:

[0046] After the cable is passed through the middle of the control frame 401, the fixed plate 203 is rotated by the handle 204, which in turn drives the worm gear 202 to rotate. The meshing of the worm gear 202 and the worm wheel 303 drives the cylindrical rod 302 to rotate, which in turn drives the cylindrical gear 304 to rotate. Under the meshing of the cylindrical gear 304 and the teeth 403, the control frame 401 rotates clockwise. Under the cooperation of the arc groove 402 and the fixed rod 505, the clamping rod 502 moves in a direction closer to each other. This clamps and fixes the cable. The inner liner 504 increases the friction with the cable surface, making the clamping more stable. Due to the self-locking principle of the worm gear 303 and worm 202, the cylindrical gear 304 is prevented from rotating, thereby preventing the control frame 401 from rotating. At the same time, under the elastic force of the spring 601, the locking rod 602 is inserted into the inner side of the corresponding fixing groove 205, which can further position the fixing plate 203 and prevent the fixing plate 203 from driving the worm 202 to rotate under the action of external force.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
