Description

Technical Field

[0001] This utility model relates to the field of copper sleeve technology, specifically a wire clamp locking structure for power engineering. Background Technology

[0002] The laying of power lines is quite strict. During the installation of lines, it is often necessary to connect multiple lines to conduct electricity. However, the current clamp connection is not very stable and is prone to damaging the wires.

[0003] Publication number CN211789606U discloses a wire clamp for power engineering. The wire drum is rotatably connected by two semi-cylinders, and a closing pin is engaged and fixed on the side of the wire drum away from the junction. The conductor tube is fixed at the center of the bottom surface of the wire drum, and a rubber tube is glued and fixed inside the bottom opening of the conductor tube. The lower and upper connecting plates have the same structure and are both located inside the wire drum. The lower connecting plate is fixedly sealed at the end of the conductor tube. A fastening pin is rotatably installed on the top surface of the upper connecting plate and engages with the top of the wire drum. The electrical connection plate is clamped inside the rubber tube. This wire clamp, through the closed limiting of the wire drum, and the adjustment of the lower and upper connecting plates, increases the conductivity stability. The adjusting pin drives the raising and lowering of the electrical connection plate, allowing the connecting wire to pass through the through hole and be securely clamped inside the conductor tube, achieving a stable connection. It not only provides stable conductivity but also protects the circuit. However, this patent still has the following problems in actual use:

[0004] The above-mentioned device is relatively simple. When in use, it cannot clamp multiple wires at the same time, so it is not convenient to use. In addition, existing wire clamps usually lock the wires by simply moving the bolts. However, this structure requires time to rotate the bolts to adjust their positions, and then the bolts press the wires down, which is not conducive to use.

[0005] A clamp locking structure for power engineering is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a wire clamp locking structure for power engineering, in order to solve the problem that the aforementioned devices in the background art are relatively simple and cannot clamp multiple wires at the same time, thus making them inconvenient to use. Furthermore, existing wire clamps usually lock the wires by simply moving the bolts, but this structure requires time to rotate the bolts to adjust their positions before the bolts can lock the wires, making the device unsuitable for use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire clamp locking structure for power engineering, comprising a wire clamp frame, wherein a plurality of limit blocks are fixedly installed at the bottom of the wire clamp frame;

[0008] A locking component is provided above the limiting block. The locking component includes a fixing frame, a lifting sleeve is slidably installed on the inner side of the fixing frame, a threaded column is slidably installed on the back side of the lifting sleeve, and the bottom end of the threaded column passes through the wire clamp frame and is provided with a pressing component.

[0009] The lifting sleeve has a cavity inside, and friction blocks are symmetrically slidably connected to both sides of the lifting sleeve. A first spring is fixedly connected between the two friction blocks. The inner side of the fixing frame has symmetrically opened inner grooves, and the friction blocks fit into the inner grooves.

[0010] The lifting sleeve is externally fixedly connected to a threaded sleeve, which is slidably connected to a threaded column.

[0011] Preferably, the lifting sleeve has an outer window on its front, and a pinching plate is symmetrically slidably connected inside the outer window. The pinching plate extends into the cavity and is fixedly connected to the friction block.

[0012] Preferably, a knob is fixedly connected to the top of the threaded post, the bottom of the threaded post slides through the wire clamp frame, and the fixing bracket is fixedly connected to the top of the wire clamp frame.

[0013] Preferably, the extrusion assembly includes a stabilizing column disposed on the side of the limiting block, a connecting column fixedly connected to the bottom end of the threaded column, a lower pressure plate rotatably connected to the bottom of the connecting column, a connecting plate fixedly connected to the side of the lower pressure plate, and the connecting plate slidably connected to the stabilizing column.

[0014] Preferably, a movable sleeve is movably installed on the outside of the connecting column, and connecting rods are symmetrically rotatably connected to both sides of the movable sleeve. A second spring is fixedly connected between the movable sleeve and the lower pressure plate, and a sliding column is fixedly connected to the bottom end of the connecting rod.

[0015] Preferably, the front of the lower pressure plate is symmetrically rotatably connected to an arc plate, and an arc groove is formed on the inner side of the arc plate.

[0016] Preferably, the sliding column is slidably connected to the arc groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this wire clamp locking structure for power engineering achieves rapid cable clamping through a rapidly moving lower pressure plate, ultimately making cable locking more convenient and avoiding the excessive time required by rotating the stud for a long time. The specific details are as follows:

[0018] 1. By squeezing the pinch plate and sliding it inside the outer window, the first spring is compressed. At this time, the pressure between the friction block and the inner groove is reduced, which in turn reduces the friction. Then, the threaded column is pressed down, causing the lower pressure plate to move down and fit against the upper surface of the cable. Then, the tool is used to turn the knob to rotate the threaded column. With the help of the threaded sleeve, the threaded column continues to descend a short distance, and finally the lower pressure plate quickly presses the cable, making the cable locking more convenient and avoiding the excessive time required by rotating the threaded column for a long time.

[0019] 2. By pressing the arc plate open when the lower pressure plate descends for the first time, and through the connection structure of the sliding column, arc groove and connecting rod, the movable sleeve rises. The second spring is stretched due to the upward movement of the movable sleeve, which gives the movable sleeve a downward restoring force. Ultimately, the arc plate can provide additional clamping force on the side of the cable, increasing the stability of the clamping. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides a technical solution: a wire clamp locking structure for power engineering, including a wire clamp frame 1, and a plurality of pairs of limiting blocks 101 are fixedly installed at the bottom of the wire clamp frame 1; the number of limiting blocks 101 is the same as that of locking components 2, and the locking components 2 are located between two limiting blocks 101 in the same pair;

[0028] A locking component 2 is provided above the limiting block 101. The locking component 2 includes a fixing frame 201. A lifting sleeve 202 is slidably installed on the inner side of the fixing frame 201. A threaded column 203 is slidably installed on the back side of the lifting sleeve 202. The bottom end of the threaded column 203 passes through the wire clamp frame 1 and is provided with a pressing component 3.

[0029] The lifting sleeve 202 has an internal cavity, and friction blocks 205 are symmetrically slidably connected to both sides of the lifting sleeve 202. A first spring 207 is fixedly connected between the two friction blocks 205. The inner side of the fixing frame 201 is symmetrically provided with inner grooves 209, and the friction blocks 205 fit into the inner grooves 209. The friction blocks 205 have an extremely high coefficient of friction, which makes the friction between them and the inner grooves 209 extremely large, thus making the lifting sleeve 202 difficult to move.

[0030] Among them, the lifting sleeve 202 is externally fixedly connected by a threaded sleeve 210, and the threaded sleeve 210 is threadedly slidably connected to the threaded column 203.

[0031] The lifting sleeve 202 has an outer window 208 on the front. A pinch plate 206 is symmetrically slidably connected inside the outer window 208. The pinch plate 206 extends into the cavity and is fixedly connected to the friction block 205.

[0032] A knob 204 is fixedly connected to the top of the threaded post 203, and the bottom of the threaded post 203 slides through the wire clamp frame 1. The fixing bracket 201 is fixedly connected to the top of the wire clamp frame 1; the bottom of the threaded post 203 passes through the top of the wire clamp frame 1.

[0033] The extrusion assembly 3 includes a stabilizing column 301 located on the side of the limiting block 101, a connecting column 304 fixedly connected to the bottom end of the threaded column 203, a lower pressure plate 302 rotatably connected to the bottom of the connecting column 304, a connecting plate 303 fixedly connected to the side of the lower pressure plate 302, and the connecting plate 303 slidably connected to the stabilizing column 301; the stabilizing column 301 is fixedly connected to the wire clamp frame 1.

[0034] A movable sleeve 305 is movably installed on the outside of the connecting column 304. Connecting rods 309 are symmetrically rotatably connected to both sides of the movable sleeve 305. A second spring 310 is fixedly connected between the movable sleeve 305 and the lower pressure plate 302. A sliding column 308 is fixedly connected to the bottom end of the connecting rod 309. The second spring 310 will pull the movable sleeve 305 down. The second spring 310 is sleeved on the outside of the connecting column 304.

[0035] The front of the lower pressure plate 302 is symmetrically rotatably connected to an arc plate 306, and an arc groove 307 is provided on the inner side of the arc plate 306.

[0036] The sliding column 308 is slidably connected to the arc groove 307; the sliding column 308 has a special structure and cannot be detached from the arc groove 307.

[0037] Working principle: Before using this type of clamp locking structure for power engineering, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, first, the cable is passed through the limiting block 101, and then the pinching plate 206 is squeezed and slid inside the outer window 208, thereby causing the first spring 207 to contract. At this time, the pressure between the friction block 205 and the inner groove 209 is reduced, which in turn reduces the friction. At this time, the threaded column 203 is pressed down, causing the lower pressure plate 302 to move down and fit against the upper surface of the cable. Then, the knob 204 is turned with a tool to rotate the threaded column 203, which, in conjunction with the threaded sleeve 210, causes the threaded column 203 to continue to descend a short distance, and finally the lower pressure plate 302 presses the cable, making the cable locking more convenient and avoiding the excessive time required by rotating the threaded column for a long time.

[0038] When the lower pressure plate 302 descends for the first time, the cable will squeeze open the arc plate 306, and through the connection structure of the sliding column 308, arc groove 307 and connecting rod 309, the movable sleeve 305 will rise. The second spring 310 will be stretched due to the upward movement of the movable sleeve 305, so that the movable sleeve 305 has a downward restoring force. Ultimately, the arc plate 306 can provide additional clamping force on the side of the cable, increasing the stability of clamping.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
