Self-locking clamp plate for electric power construction

Abstract

This utility model discloses a self-locking clamp for power construction, belonging to the field of power construction technology. It includes: a lower clamp with a first T-shaped slot inside; and an upper clamp with a first T-shaped block fixedly connected to its bottom. The first T-shaped block is inserted into the first T-shaped slot. This utility model achieves vertical self-locking through the insertion and cooperation of the first T-shaped block with the first T-shaped slot and the second T-shaped block with the second T-shaped slot. Simultaneously, the locking blocks on both sides of the upper clamp are inserted into the slots on both sides of the lower clamp's housing. The locking blocks press against the arc-shaped portion of the locking pin, causing the locking pin to compress the spring and then reset, locking the locking block to form a horizontal self-locking mechanism. The insertion of the elastic plate into the arc-shaped slot further enhances stability. It eliminates the need for bolt connections, effectively avoiding the loosening and falling off problems caused by improper installation or bolt failure in traditional clamps, ensuring the reliability of line operation. Furthermore, unlocking only requires pressing down the locking pin to release the locking block.

[0006] As a further preferred embodiment of this technical solution: the two card blocks are slidably connected inside the two card slots respectively.

[0007] As a further preferred embodiment of this technical solution: the lower clip has two second T-shaped slots inside, and the bottom of the upper clip is fixedly connected to two second T-shaped blocks, which are respectively inserted into the two second T-shaped slots.

[0008] As a further preferred embodiment of this technical solution: the upper clamping piece has an arc-shaped slot on its outside, and an elastic piece is fixedly connected to the lower clamping piece, the elastic piece being inserted into the inside of the arc-shaped slot.

[0009] As a further preferred embodiment of this technical solution: the spring is located below the locking pin.

[0010] As a further preferred embodiment of this technical solution: the thickness of the card block is less than the width of the card slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention achieves vertical self-locking through the insertion and engagement of the first T-shaped block with the first T-shaped slot and the second T-shaped block with the second T-shaped slot. Simultaneously, the locking blocks on both sides of the upper clamping plate are inserted into the slots on both sides of the lower clamping plate housing. The locking blocks press against the arc-shaped part of the locking pin, causing the locking pin to compress the spring and then reset to lock the locking block, forming a horizontal self-locking. The engagement of the elastic plate with the arc-shaped slot further enhances stability. It does not rely on bolt connections, effectively avoiding the loosening and falling off problems caused by improper installation or bolt failure of traditional wire clamps, ensuring the reliability of line operation. Moreover, unlocking only requires pressing down the locking pin to release the locking block, making the operation convenient and efficient. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] Please see Figures 1-4This utility model provides a technical solution: a self-locking clamp for power construction, comprising: a lower clamping piece 1, an upper clamping piece 2, a first T-shaped slot 3, a first T-shaped block 4, and two housings 9. The first T-shaped slot 3 is opened inside the lower clamping piece 1, and the first T-shaped block 4 is fixedly connected to the bottom of the upper clamping piece 2 and inserted into the interior of the first T-shaped slot 3.

[0021] In this embodiment, specifically: two housings 9 are fixedly connected to both sides of the lower clamping piece 1, a slot 11 is provided on the outside of the housing 9, a sliding groove 12 is provided inside the housing 9, a locking pin 14 is slidably connected inside the sliding groove 12, an arc-shaped part 15 is provided at the end of the locking pin 14, and a spring 13 is provided inside the sliding groove 12; two locking blocks 10 are fixedly connected to both sides of the two upper clamping pieces 2, two second T-shaped slots 5 are provided inside the lower clamping piece 1, two second T-shaped blocks 6 are fixedly connected to the bottom of the upper clamping piece 2, the two second T-shaped blocks 6 are respectively inserted into the interior of the two second T-shaped slots 5, and the two locking blocks 10 are slidably connected to the interior of the two slots 11.

[0022] When in use, place the cable in the groove of the lower clip 1, then place the upper clip 2 on one side of the lower clip 1, push the upper clip 2, insert the first T-shaped block 4 into the first T-shaped slot 3, and insert the second T-shaped block 6 into the second T-shaped slot 5 to complete the vertical self-locking.

[0023] At the same time, the locking block 10 is inserted into the slot 11 as the upper clamping piece 2 moves. When the locking block 10 passes the arc-shaped part 15 of the locking pin 14, it presses down the locking pin 14 to the rear of the locking pin 14. Then the locking pin 14 is popped out by the spring 13, and the locking block 10 is thus locked by the locking pin 14, completing the lateral self-locking.

[0024] When it is necessary to unlock the self-locking mechanism, use a tool that can be inserted into the slot 11 to press down the latch 14, thereby releasing the latch block 10 and unlocking the self-locking mechanism.

[0025] In this embodiment, specifically: in order to further increase the stability of the connection, an arc-shaped slot 7 is provided on the outside of the upper clip 2, and an elastic piece 8 is fixedly connected to the lower clip 1, with the elastic piece 8 inserted into the inside of the arc-shaped slot 7.

[0026] In this embodiment, specifically, the spring 13 is located below the locking pin 14.

[0027] In this embodiment, specifically, the thickness of the card block 10 is less than the width of the card slot 11.

[0028] Working principle: When in use, place the cable in the groove of the lower clamp 1, then place the upper clamp 2 on one side of the lower clamp 1, push the upper clamp 2, insert the first T-shaped block 4 into the first T-shaped slot 3, and insert the second T-shaped block 6 into the second T-shaped slot 5 to complete the vertical self-locking.

[0029] At the same time, the locking block 10 is inserted into the slot 11 as the upper clamping piece 2 moves. When the locking block 10 passes the arc-shaped part 15 of the locking pin 14, it presses down the locking pin 14 to the rear of the locking pin 14. Then the locking pin 14 is popped out by the spring 13, and the locking block 10 is thus locked by the locking pin 14, completing the lateral self-locking.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
