Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliance technology, and more specifically, it relates to an anti-loosening wire clamping structure for low-voltage electrical appliances. Background Technology

[0002] Low-voltage electrical appliances are components or devices that can manually or automatically connect or disconnect circuits according to external signals and requirements, so as to achieve switching, control, protection, detection, transformation and adjustment of circuits or non-electrical objects. The design of multiple circuits will make the circuit connection relatively loose during use, and they need to be clamped and fixed.

[0003] According to the Chinese patent publication number "CN206516769U" entitled "Anti-loosening wire clamping device for low-voltage electrical appliances", the two ends of the rotating shaft extend into the mounting groove and are rotatably connected to the mounting groove. The other side of the rotating plate is provided with multiple wire holes at equal intervals, and the top of the rotating plate is provided with multiple threaded holes, which are located directly above the wire holes. A wing bolt is threaded into the threaded hole, and the lower end of the wing bolt extends into the interior of the wire hole. An arc-shaped pressure plate is fixed to the lower end of the wing bolt. This design achieves a novel structure, ingenious design, reasonable structure, small space occupation, and the ability to fix multiple wires.

[0004] However, in actual use, on the one hand, when the device performs the wire clamping function, it is necessary to manually rotate a single threaded rod to move it down and clamp the electrical wire. If there are many wires to be clamped, the user needs to rotate the threaded rods one by one. The operation of clamping too many wires takes a lot of time and its work efficiency is relatively low. On the other hand, its clamping and locking structure does not have a device to protect the wires. The large clamping force will cause damage to the wires and reduce the service life of the clamped wires.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes an anti-loosening wire clamping structure for low-voltage electrical appliances. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-loosening wire clamping structure for low-voltage electrical appliances.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage electrical appliance anti-loosening clamping structure, including a base, on which a clamping seat is fixedly installed, and the interior of the clamping seat has a plurality of through slots arranged in an array along the length direction of the clamping seat, and further including:

[0008] A clamping assembly for clamping wires passing through the through slot includes an arc-shaped piece movably disposed inside the through slot. The upper end of the arc-shaped piece is provided with a telescopic sleeve, which allows the arc-shaped piece to flexibly press down and clamp the circuit through the telescopic sleeve.

[0009] An actuation component, used to drive a clamping component to synchronously clamp the wire, includes multiple threaded rods arrayed inside the clamping seat, the lower end of each threaded rod corresponding to a through slot. The upper end of the clamping seat is provided with multiple fixing rods, and every two fixing rods are fixedly installed at the two ends of the threaded rods. A fixing plate is fixedly installed at the upper end of the fixing rod, and an actuation gear is rotatably installed at the upper end of the fixing plate. A driving component is provided on one side of the actuation gear, and the driving component can drive the actuation gear to complete the rotation action.

[0010] Preferably, the telescopic kit includes a telescopic sleeve rotatably disposed at the bottom end of the threaded rod, a telescopic spring being movably installed inside the telescopic sleeve, one end of the telescopic spring being connected to a telescopic rod, and the telescopic rod being able to move up and down inside the telescopic sleeve.

[0011] Preferably, the driving component includes two mounting rods disposed on the upper end of the clamping seat, the upper ends of the two mounting rods are provided with a fixing plate, the upper end of the fixing plate is movably provided with a driving tooth plate along the length direction of the fixing plate, the driving tooth plate is provided with teeth on the side facing the actuating gears, and the teeth mesh with multiple actuating gears.

[0012] Preferably, the fixed plate has a movable groove, and a connecting block is movably installed inside the movable groove. The bottom end of the connecting block extends to the outside of the movable groove and is provided with a driving cylinder.

[0013] Preferably, the top end of the arc-shaped piece is fixedly connected to the bottom end of the telescopic rod, and the cross-section of the arc-shaped piece has an arc.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the rotation of the actuating gear causes the threaded rod connected to it to rotate accordingly. Since the height of the actuating gear is fixed, the clamping seat and the threaded rod are also connected by threads. The threaded rod will move vertically inside the clamping seat, thereby driving the telescopic rod to move downward. The design of multiple clamping components can clamp multiple wires simultaneously without multiple controls, making the operation simple and improving the work efficiency of the staff.

[0016] 2. In this utility model, the telescopic rod moves downward, causing the arc-shaped piece to move. The arc-shaped piece presses the surface of the wire passing through the through groove, thereby achieving a clamping effect. When the wire is pressed, the telescopic spring inside the arc-shaped piece begins to compress, elastically clamping the wire and protecting the rigid contact between the wire surface and the clamping component. At the same time, the telescopic spring can clamp wires of different sizes. Attached Figure Description

[0024] like Figure 1-5 As shown, this utility model provides an anti-loosening clamping structure for low-voltage electrical appliances, including a base 1, a clamping seat 2 fixedly installed on the base 1, and a plurality of through slots 3 arrayed along the length direction of the clamping seat 2 inside the clamping seat 2.

[0025] The drive component 6 can drive the actuating gear 502 to complete the rotation action. The drive component 6 includes two mounting rods 602 set on the upper end of the clamping seat 2. The upper end of the two mounting rods 602 is provided with a fixing plate 601. The upper end of the fixing plate 601 is movably provided with a drive tooth plate 7 along the length direction of the fixing plate 601. The drive tooth plate 7 has teeth on the side facing the actuating gear 502, and the teeth mesh with multiple actuating gears 502. The fixing plate 601 is provided with a moving groove 605. A connecting block 604 is movably installed inside the moving groove 605. The bottom end of the connecting block 604 extends to the outside of the moving groove 605 and is provided with a drive cylinder 603.

[0026] The cylinder 603 is driven to operate, and its telescopic end drives the connecting block 604 to move laterally in the moving groove 605. The moving connecting block 604 drives the drive tooth plate 7 to move laterally along its length on the surface of the fixed plate 601. When the drive tooth plate 7 moves, it will drive the multiple actuating gears 502 that mesh with it to rotate.

[0027] The execution component 5 is used to drive the clamping component 4 to perform synchronous clamping action on the wire. It includes multiple threaded rods 501 arranged in an array inside the clamping base 2. The lower end of each threaded rod 501 corresponds to the position of the through groove 3. The upper end of the clamping base 2 is provided with multiple fixing rods 503. Every two fixing rods 503 are fixedly installed at both ends of the threaded rods 501. The upper end of the fixing rods 503 is fixedly installed with a fixing plate 504. The upper end of the fixing plate 504 is rotatably installed with an execution gear 502. A drive component 6 is provided on one side of the execution gear 502.

[0028] When the actuating gear 502 rotates, the threaded rod 501 connected to it will rotate. Since the height of the actuating gear 502 is fixed, the clamping seat 2 and the threaded rod 501 are also connected by threads. The threaded rod 501 will move vertically inside the clamping seat 2, thereby driving the telescopic rod 403 to move downward.

[0029] The clamping assembly 4 is used to clamp the wire passing through the through groove 3. It includes an arc-shaped piece 401, which is movably disposed inside the through groove 3. The upper end of the arc-shaped piece 401 is provided with a telescopic kit. The telescopic kit allows the arc-shaped piece 401 to flexibly press down and clamp the circuit. The telescopic kit includes a telescopic sleeve 402 rotatably disposed at the bottom end of the threaded rod 501. A telescopic spring 404 is movably installed inside the telescopic sleeve 402. One end of the telescopic spring 404 is connected to a telescopic rod 403. The telescopic rod 403 can move up and down inside the telescopic sleeve 402. The top end of the arc-shaped piece 401 is fixedly connected to the bottom end of the telescopic rod 403. The cross-section of the arc-shaped piece 401 is curved.

[0030] When the telescopic rod 403 moves downward, the arc-shaped piece 401 presses the surface of the wire passing through the through groove 3, thereby achieving a clamping effect. When the wire is pressed, the telescopic spring 404 inside the arc-shaped piece 401 begins to compress, elastically clamping the wire.
