Detailed Implementation

[0023] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 4As shown in the figure, a low-voltage line clamp for a power distribution network provided by this utility model includes a support plate 1, a pressure block 2, a transmission block 3, a pull rod 4, and a limiting ring 5. The rear side of the pressure block 2 contacts the support plate 1. The side of the transmission block 3 near the pressure block 2 is rotatably connected to the pressure block 2. The side of the pull rod 4 near the transmission block 3 is rotatably connected to the transmission block 3. The side of the pull rod 4 away from the transmission block 3 passes through the limiting ring 5 and extends to the outside of the limiting ring 5. The rear side of the limiting ring 5 is fixedly connected to the support plate 1. A baffle 6 is provided at the top of the front side of the support plate 1. A transmission device 7 that works with the baffle 6 is provided at the top of the rear side of the support plate 1. A reset device 8 that works with the transmission device 7 is provided at the bottom of the rear side of the support plate 1. Limiting posts 9 that work with the transmission device 7 are provided on the left and right sides of the top of the support plate 1. A limiting plate 10 is provided at the top of the limiting posts 9.

[0026] refer to Figure 1 and Figure 2 The top and bottom of the limiting post 9 are fixedly connected to the support plate 1 and the limiting plate 10 respectively, and the rear support plate 1 of the baffle 6 is in contact with the pressure block 2.

[0027] The above solution is adopted: by setting the limiting post 9 and the limiting plate 10, the connecting plate 703 can be limited, and by setting the baffle 6, the wire can be protected.

[0028] refer to Figure 3 The transmission device 7 includes a lifting plate 701, the surface of which is provided with a stroke hole 702, and a connecting plate 703 is provided on the right side of the top of the lifting plate 701.

[0029] The above solution involves setting up a transmission device 7, which can automatically open or close the baffle 6, making it convenient for operators to protect the wires.

[0030] refer to Figure 4 The reset device 8 includes a drive shaft 801, a support block 802 is provided on the rear side of the drive shaft 801, a push plate 803 and a torsion spring 804 are respectively sleeved on the front and rear sides of the surface of the drive shaft 801, and a push column 805 is provided on the rear side of the push plate 803 away from the drive shaft 801.

[0031] The above solution is adopted: by setting the reset device 8, the pressure block 2 and the transmission device 7 can be automatically reset, so that after the pressure block 2 is opened, it can be automatically reset and the wire can be automatically clamped.

[0032] refer to Figure 3 The bottom of the connecting plate 703 is fixedly connected to the lifting plate 701, the top of the connecting plate 703 is sleeved on the surface of the limiting post 9, and the front side of the connecting plate 703 is fixedly connected to the baffle 6.

[0033] The above scheme is adopted: by setting up the lifting plate 701, the connecting plate 703 can be raised and lowered; by setting up the stroke hole 702, the push column 805 can be limited; and by setting up the connecting plate 703, the baffle 6 can be raised and lowered.

[0034] refer to Figure 2 , Figure 3 and Figure 4 The front side of the drive shaft 801 passes through the support plate 1 and extends to the outside of the support plate 1 and is fixedly connected to the drive block 3. The rear side of the drive shaft 801 is fixedly connected to the support block 802. The push plate 803 is fixedly connected to the drive shaft 801. The front and rear sides of the torsion spring 804 are fixedly connected to the push plate 803 and the support block 802 respectively. The front side of the push column 805 is fixedly connected to the push plate 803. The rear side of the push column 805 passes through the stroke hole 702 and extends to the inner cavity of the stroke hole 702 and contacts the inner wall of the stroke hole 702.

[0035] The above scheme is adopted as follows: by setting the transmission shaft 801, the support block 802 and the push plate 803 can rotate synchronously and twist the torsion spring 804. By setting the support block 802, the torsion spring 804 can be supported. By setting the push plate 803, the push column 805 can be driven to rotate in the inner cavity of the stroke hole 702. By setting the push column 805, the lifting plate 701 can be lifted up and down. By setting the torsion spring 804, the rebound force released after twisting can drive the support block 802, the transmission shaft 801 and the push plate 803 to rotate in the opposite direction, so that the baffle 6 automatically descends to protect the wire. It can also drive the transmission block 3 to rotate in the opposite direction through the transmission shaft 801, so that the pressure block 2 automatically presses down the wire.

[0036] The working principle of this utility model:

[0037] When in use, the operator pushes the lever 4, which drives the transmission block 3, the transmission shaft 801 and the support block 802 to rotate synchronously and twist the torsion spring 804. During the rotation of the transmission block 3, the pressure block 2 will move downward, causing the pressure block 2 to open.

[0038] Meanwhile, as the drive shaft 801 rotates, it drives the push plate 803 to rotate synchronously. The push plate 803 drives the push column 805 to rotate in the inner cavity of the stroke hole 702. During the rotation of the push column 805 in the inner cavity of the stroke hole 702, it will squeeze the lifting plate 701. The squeezing force generated at this time will push the lifting plate 701 to move upward. The lifting plate 701 will drive the connecting plate 703 to move upward synchronously. The connecting plate 703 will drive the baffle 6 to move upward synchronously, so that the baffle 6 no longer protects the opening between the support plate 1 and the pressure block 2. At this time, the operator can place the wire between the support plate 1 and the pressure block 2.

[0039] After placement, the operator stops pushing the lever 4. At this time, the rebound force released by the torsion spring 804 after twisting will drive the push plate 803 and the transmission shaft 801 to rotate synchronously in opposite directions. The push plate 803 will drive the push column 805 to rotate in opposite directions in the inner cavity of the stroke hole 702. The push column 805 will push the lifting plate 701 to move downward. The lifting plate 701 will drive the connecting plate 703 to move downward synchronously. The connecting plate 703 will drive the baffle 6 to move downward synchronously to protect the wire and prevent the wire from detaching from the support plate 1 and the pressure block 2.

[0040] At the same time, the drive shaft 801 will drive the drive block 3 to rotate synchronously in the opposite direction. The drive block 3 will drive the pull rod 4 to extend outward, and at the same time, it will also drive the pressure block 2 to move upward, so that the pressure block 2 automatically presses down on the wire. When the operator stops pulling the pull rod 4, the pressure block 2 can continue to press down on the wire, preventing the wire clamp from shifting when the pull rod 4 of the wire clamp is not pulled.

[0041] In summary, this low-voltage line clamp for power distribution networks, through the coordinated use of baffle 6, transmission device 7, reset device 8, limit post 9, and limit plate 10, solves the problem of existing low-voltage line clamps for power distribution networks where operators must first push the lever to open the clamp, then place the conductor between the pressure block and the support plate, and after the conductor is placed, manually pull back the lever to clamp the conductor and manually close the safety baffle to prevent the conductor from detaching from the pressure block and the support plate. The entire process involves multiple manual operations, requiring pushing the lever to open the clamp, manually closing the baffle, and pulling back the lever, which is time-consuming and labor-intensive.
