Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] Disclosed is a rotating fixture for a surge protector, the overall structure of which is as follows Figure 1-Figure 2 The rotary clamp mainly comprises a disc body 1, a clamp body 2 and an assembly component 3. The disc body 1 has a side 11 of an annular structure, and the side 11 surrounds a cavity 12. In particular, the side 11 can be a circular ring connected end to end, or a quasi-circular ring composed of a plurality of arc-shaped protrusions.

[0023] The clamp body 2 is concentrically arranged in the cavity 12, and at least one assembly groove 21 is provided at the edge of the clamp body 2 (four symmetrically distributed assembly grooves are shown in the figure). The assembly component 3 is fixed in the assembly groove 21 by bolts, and is used to clamp and assemble the surge protector under the interaction between the disc body 1 and the clamp body 2. In particular, the disc body 1 and the clamp body 2 can rotate relative to each other, and the inner side of the side 11 is provided with a protrusion 13 extending into the cavity 12, and the protrusion 13 cooperates with the assembly component 3 to achieve the clamping of the surge protector. The assembly component 3 is also provided with a yield structure 4 to accommodate surge protectors of different heights.

[0024] A power driving member (not shown in the figure) is provided at the bottom of the disc body 1, and the power driving member is used to drive the clamp body 2 or the disc body 1 to rotate, that is, the power driving member can be connected to the bottom of the disc body 1, drive the disc body 1 to rotate, cooperate with the clamp body 2 to clamp, and be equipped with a surge protector; or the power driving member can be connected to the bottom of the clamp body 2, drive the disc body 1 to rotate, cooperate with the clamp body 2 to clamp, and be equipped with a surge protector. In particular, the power driving member can be a rotary cylinder, a rotary motor, an electromagnetic rotary device, etc.

[0025] Specifically, Figure 3As shown, the assembly component 3 includes a fixed part 31 and a movable part 32. The fixed part 31 is assembled in the assembly groove 21 by a fastener (such as a screw), and the movable part 32 is movably arranged at one end of the fixed part 31. After the movable part 32 is connected to the fixed part 31, a groove 33 for accommodating the surge protector is formed. The yield structure 4 is arranged on the movable part 32, so that the movable part 32 can be adaptively adjusted according to the height of the surge protector. At the same time, the movable part 32 abuts against the protrusion 13, thereby clamping the surge protector, and a gap is provided between the movable part 32 and the inner side of the side 11 to ensure that the movable part 32 can move flexibly.

[0026] In particular, the side 11 is a circular structure as a whole, the raised portion 13 is arranged on its inner side, and smooth transition curves 111 are also provided at both ends of the raised portion 13 to facilitate the linear movement of the movable part, that is, the raised portion 13 fills the gap between the movable part 32 and the inner side of the side 11.

[0027] like Figure 4-Figure 8 As shown, a slide groove 311 is provided at the end of the fixed member 31, and sliding arms 321 that slide with the slide groove 311 are provided on both sides of the movable member 32. This sliding fit structure enables the movable member 32 to move smoothly on the fixed member 31. In addition, a buffer member 5 is also provided in the slide groove 311, and one end of the buffer member 5 is connected to the side wall of the slide groove 311. When the movable member 32 moves toward the groove 33, it will squeeze the buffer member 5, thereby playing a role of buffering and shock absorption.

[0028] The buffer 5 includes a buffer portion 51 and a suction cup portion 52 arranged at both ends of the buffer portion 51. The suction cup portion 52 has a negative pressure area, which can be closely abutted against the side wall of the slide groove 311 and the sliding arm 321 respectively, thereby enhancing the stability of the connection. The buffer portion 51 includes two first deformation sections 511 and second deformation sections 512 that change step by step. This multi-stage deformation design can more effectively absorb and disperse the impact force. At the same time, the buffer portion 51 is a hollow structure, which further improves its buffering performance. The yield structure 4 is still arranged on the movable part 32 to adapt to surge protectors of different heights.

[0029] Specifically, a limiting cavity 3111 for accommodating the buffer member 5 is further provided in the slide groove 311. The limiting cavity 3111 is used to connect the buffer member 5 and limit the circumference of the buffer member 5 to prevent the first deformation section 511 and the second deformation section 512 from deforming and offsetting due to the oblique force.

[0030] The yielding structure 4 includes a contact member 41. A movable groove 322 for accommodating the contact member 41 is provided at one end of the movable member 32, a guide column 323 is provided in the movable groove 322, and a guide groove 411 cooperating with the guide column 323 is provided on the contact member 41. This guide matching structure enables the contact member 41 to move stably in the movable groove 322. At the same time, an elastic member 42 (such as a compression spring) is also provided between the contact member 41 and the movable groove 322 to provide a restoring force. An arc portion 412 is provided at one end of the contact member 41 close to the side 11. When the protrusion 13 contacts the arc portion 412, the movable member 32 is pushed to move, thereby achieving the clamping of the surge protector.

[0031] The elastic member 42 can be selected to be one or more combinations of materials such as compression springs, sponge blocks, silicone blocks or high-density plastics. In this embodiment, the elastic member 42 is sleeved on the guide column 323, and one end thereof abuts against one end of the contact member 41. This design enables the elastic member 42 to transmit pressure evenly and has good elasticity and durability.

[0032] The shape of the groove 33 can be designed to be a rectangular or convex shape to adapt to surge protectors of different shapes and sizes. The surge protector can be erected or laid flat in the groove 33, thereby improving the versatility and flexibility of the clamp.

[0033] The suction cup portion 52 includes a disc edge 521 of a disc-shaped structure and at least one anti-sliding block 522. This design increases the connection strength of the suction cup portion 52 to prevent it from falling off or being damaged when subjected to force. The anti-sliding block 522 can be made of a wear-resistant and slip-resistant material, such as rubber or silicone, to further improve the stability and reliability of the connection.

[0034] The material of the buffer 5 can be selected from one or more combinations of rubber, silicone, soft PVC or porous ceramics. These materials have good elasticity and buffering properties, can effectively absorb and disperse impact force, and protect the surge protector from damage. At the same time, these materials also have good wear resistance and corrosion resistance, which can extend the service life of the clamp.

[0035] The rotating fixture in this embodiment can adjust the shape of the groove 33 according to actual needs, so that the surge protector can be placed upright or flat in the groove 33. It can also cooperate with different external processing equipment to align the side for engraving or processing while clamping and assembling the surge protector.

[0036] In summary, the rotary clamp for surge protector provided in this embodiment has the advantages of compact structure, easy operation, strong adaptability and good protection effect, etc. By cleverly designing the disc body, clamp body and assembly components, and selecting suitable materials and processes for manufacturing, the clamp can meet the clamping and assembly requirements of surge protectors of different models and specifications.
