[0002] During the installation of power equipment, it is often necessary to wire the transmission cables. The traditional method is to manually wrap the wiring, add U-shaped cards to clamp the wiring, or use some wiring clamps to squeeze the wire ends to connect and clamp. However, during use, power equipment often generates vibrations of a certain frequency. Due to the continuous occurrence of the vibration frequency, once the connection position is not firm, loosening will occur. At the least, it will affect the stability of power transmission, and at worst, it will disconnect and fall off to the equipment, increasing the safety risks of the equipment. Therefore, there is an urgent need for a shock-absorbing clamping device for the wiring terminal of power equipment. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-7 A shock-absorbing clamping device for a terminal of an electric power equipment comprises a base 1, a plurality of shock-absorbing components 2 are installed at the bottom of the base 1, lower clamping seats 3 are installed on both sides of the top plate of the base 1, a plurality of upper clamping seats 4 are vertically movably arranged on the lower clamping seats 3, and a connecting plate 41 is connected to the top of each upper clamping seat 4. A main top plate 34 is fixedly arranged above the top of the base 1 between the lower clamping seats 3 on both sides, a threaded rod 5 is vertically inserted through the main top plate 34, a nut 52 for driving the threaded rod 5 to move vertically is rotatably arranged above the main top plate 34, and both sides of the bottom of the threaded rod 5 are fixedly connected to the connecting plate 41 through fixing members 42.

[0018] Among them, four shock absorbing components 2 are fixedly installed at the bottom of the base 1, and the shock absorbing components 2 are all installed at the corners of the base 1. Through the arrangement of the shock absorbing components 2, the shock absorption of the base 1 can be achieved, thereby achieving the shock absorption of the connection of the terminal.

[0019] Among them, the energy storage element in the shock absorber can absorb and store part of the vibration energy when the device is subjected to external vibration. Taking the spring as an example, when external vibration acts on the device, the spring will undergo elastic deformation, converting the vibration energy into the potential energy of the spring and storing it. In this way, the spring plays a role in buffering and reducing the impact force of vibration. After the vibration, the spring will gradually return to its original state, releasing the stored energy and restoring the device to a stable state. It is worth noting that the specific structure of the shock absorbing component 2 and its working method are both existing technologies currently disclosed on the market, and they do not belong to the main technical problems that need to be solved in this technical solution, so they are not elaborated in the present invention.

[0020] Among them, both sides of the top of the lower clamp seat 3 are downwardly provided with a plurality of clamping cavities 31, both sides of the upper clamp seat 4 are adapted to the clamping cavities 31, and the upper clamp seat 4 is adapted to be inserted into the clamping cavities 31. Through the adaptation setting between the clamping cavities 31 and the upper clamp seat 4, the upper clamp seat 4 can be guided during the movement process, thereby improving the stability of the device during use.

[0021] The top of the upper clamp seat 4 in the lower clamp seat 3 on each side is fixedly connected through a connecting plate 41, and a fixing piece 42 is fixedly connected to the top of the connecting plate 41, and the end of the fixing piece 42 is fixedly connected to the bottom of the threaded rod 5. Through the setting of the fixing piece 42, the connecting plates 41 on both sides can be fixedly connected to the threaded rod 5, so that the upper clamp seat 4 at the bottom of the connecting plate 41 can move vertically synchronously with the threaded rod 5, so that the clamping and fixing of the device terminal can be achieved through the movement of the upper clamp seat 4.

[0022] Among them, support columns 32 are fixedly arranged vertically upward at the corners of the top of the lower clamp seat 3, and the tops of the support columns 32 are fixedly connected to the side top plates 33, and the main top plates 34 are fixedly connected between the side top plates 33 on both sides. Through the arrangement of the support columns 32, the side top plates 33 and the main top plates 34 can be fixedly supported, so that the threaded rod 5 can be fixedly installed.

[0023] Among them, the support column 32 is fixedly provided with a guide card 321 on one side facing the connecting plate 41, and the connecting plate 41 is adapted to be provided with a guide card slot 40 corresponding to the guide card 41. Through the adaptation between the guide card 41 and the guide card slot 40, the connecting plate 41 can be guided when it moves vertically, thereby improving the stability of the device during use.

[0024] Among them, the main top plate 34 is adapted to be penetrated by a threaded hole corresponding to the threaded rod 5, and an annular clamp 35 is fixedly arranged in the middle above the main top plate 34. The annular clamp 35 is located outside the threaded hole, and the diameter of the annular clamp 35 is larger than the diameter of the threaded hole. A nut 52 is sleeved on the threaded rod 5 above the main top plate 34, and an annular clamp cavity is adapted to be arranged at the bottom of the nut 52 corresponding to the annular clamp 35. Through the setting of the annular clamp 35, the positioning of the nut 52 can be achieved, so that the nut 52 can be fixed and rotated at the top of the main top plate 34, so that the threaded rod 5 can be driven to move vertically through the rotation of the nut 52.

[0025] Among them, a spring 6 is vertically installed on one side of the top of the fixing member 42 close to the threaded rod 5, and the other end of the spring 6 is connected to the main top plate 34. Through the setting of the spring 6, an elastic force downward on the fixing member 42 can be provided, thereby improving the clamping effect of the terminal.

[0026] In this embodiment, when the user needs to connect the cables of the connection terminals on both sides, the user only needs to place the cables on both sides above the lower clamping seat 3 and then connect the cables on both sides together.

[0027] When the user places the cables, he only needs to rotate the nut 52 with a wrench, so that the threaded rod 5 can be driven to move vertically by the rotation of the nut 52. When the threaded rod 5 moves upward, the fixing member 42 at the bottom of the threaded rod 5 can drive the connecting plate 41 and the upper clamping seat 4 to move upward synchronously. Thus, the upper clamping seat 4 can be moved upward out of the clamping cavity 31, and the user can place the cables on both sides.

[0028] Furthermore, when the user has placed the cables, he can use a wrench to rotate the nut 52 in the opposite direction, and the threaded rod 5 can move downward, and the fixing member 42 at the bottom of the threaded rod 5 can drive the connecting plate 41 and the upper clamping seat 4 to move downward synchronously. At this time, the upper clamping seat 4 can move into the clamping cavity 31 on the lower clamping seat 3, and the cables on both sides can be fixed by clamping between the upper clamping seat 4 and the lower clamping seat 3.

[0029] Furthermore, by providing the shock absorbing assembly 2, the base 1 can be shock-absorbing, thereby achieving shock absorption of the device and the clamped cables, thereby effectively preventing the wiring terminals of the power equipment from becoming loose.

[0030] Furthermore, an annular clamp 35 is fixedly disposed above the main top plate 34, and the annular clamp 35 is adapted to be clamped in the annular clamping cavity at the bottom of the nut 52. Since the connection between the annular clamp 35 and the annular clamping cavity is made of smooth material, the nut 52 can be fixed by the annular clamp 35. The nut 52 can also be rotated at the top of the main top plate 34, so that the threaded rod 5 can be driven to move vertically by the nut 52.

[0031] Furthermore, by setting the spring 6, a downward elastic force can be applied to the fixing member 42, thereby increasing the downward clamping force of the upper clamp seat 4, thereby increasing the clamping force between the lower clamp seat 3 and the upper clamp seat 4, and thus improving the clamping performance of the cable.

[0032] In the present invention, the shock absorption of the device can be achieved through the setting of the shock absorbing assembly 2, the vertical movement of the upper clamp seat 4 can be controlled through the setting of the threaded rod 5 and the spring 6, and the clamping of the cable can be achieved through the adapter between the clamping cavity 31 on the lower clamp seat 3 and the upper clamp seat 4, thereby achieving the clamping of the cables on both sides, so as to improve the connection stability of the wiring terminals of the power equipment, which not only improves the stability during power transmission, but also reduces safety risks.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
