Description

Technical Field

[0001] This application relates to the field of clamping device technology, specifically providing a clamp. Background Technology

[0002] In industrial production and daily life, it is often necessary to fix objects together, such as fixing multi-layered sheet structures during cutting operations or fixing the shell and body of household appliances. Currently, there are several commonly used fixing methods, such as fixing with screws, clips, and special clamps. However, screw connections can easily damage the structure of the object itself, and for objects that need to be frequently disassembled and reassembled, the screws are prone to stripping, requiring re-drilling and connection, which is difficult to operate. Clip connections are prone to objects falling off due to insufficient clamping force. Although special clamps have better clamping force, their structure is complex, their versatility is poor, and their manufacturing cost is high. Utility Model Content

[0003] In view of the above, it is necessary to propose a clamp to solve the problems of complex structure, cumbersome operation and poor clamping effect.

[0004] This application provides a clamp, comprising: an elastic frame including a body portion, a first connecting end, and a second connecting end, the first connecting end and the second connecting end being respectively disposed at both ends of the body portion, both the first connecting end and the second connecting end being bent in a direction away from the body portion, and the first connecting end and the second connecting end being disposed opposite to each other; a first clamping piece connected to the first connecting end; a second clamping piece connected to the second connecting end and disposed opposite to the first clamping piece, the second clamping piece and the first clamping piece being parallel to each other; and a locking member movably inserted into the first connecting end, the locking member abutting against the side of the first clamping piece away from the second clamping piece; wherein, the first clamping piece and the second clamping piece cooperate to clamp an object, and the locking member is configured to push the first clamping piece toward the second clamping piece to clamp the object.

[0005] The clamp provided in this application embodiment provides elastic force through an elastic skeleton. A first clamping piece and a second clamping piece are respectively connected to the first and second connecting ends of the elastic skeleton. When clamping an object, both the first and second clamping pieces abut against the object, thus effectively improving clamping stability. The elastic force provided by the elastic skeleton drives the first and second clamping pieces to clamp the object. A locking member pushes the first clamping piece towards the object, increasing the clamping force and improving the clamping effect. The above-described clamp has a simple structure; in use, simply abut the first and second clamping pieces against the object and tighten the locking member. It is convenient to operate and provides good clamping effect.

[0006] In some embodiments, one side of the first clamping piece is connected to the first connecting end, and the other side of the first clamping piece extends toward the body portion; one side of the second clamping piece is connected to the second connecting end, and the other side of the second clamping piece extends away from the body portion.

[0007] In some embodiments, the elastic skeleton is a ring structure with an opening.

[0008] In some embodiments, the clamp further includes a pad disposed between the first clamping piece and the second clamping piece, one side of the pad being configured to abut against the object and the other side being configured to abut against the first clamping piece or the second clamping piece.

[0009] In some embodiments, there are multiple elastic skeletons, which are arranged sequentially at intervals. The first connecting end of each elastic skeleton is connected to the first clamping piece, and the second connecting end of each elastic skeleton is connected to the second clamping piece.

[0010] In some embodiments, the number of locking members is set to multiple, and the multiple locking members are connected one-to-one with the first connecting end of each of the multiple elastic skeletons, and each locking member abuts against the first clamping piece.

[0011] In some embodiments, both the side of the first clamping piece facing the second clamping piece and the side of the second clamping piece facing the first clamping piece are provided with anti-slip surfaces, which are used to abut against the object.

[0012] In some embodiments, the clamp further includes a first flexible member and a second flexible member, the first flexible member being disposed on the side of the first clamping piece facing the second clamping piece, and the second flexible member being disposed on the side of the second clamping piece facing the first clamping piece, both the first flexible member and the second flexible member being used to flexibly abut against the object.

[0013] In some embodiments, the locking member includes a connecting portion and a screwing portion connected together. The connecting portion is connected to the first connecting end, and the screwing portion is disposed at the end of the connecting portion away from the first clamping piece. The screwing portion is used to drive the connecting portion to move toward or away from the first clamping piece under the action of an external force.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0022] Please see Figure 1 and Figure 2This application provides a clamp 100 for clamping an object (not shown). The object can be a structural component composed of multiple plate-shaped objects, the housing of a household appliance, etc. The clamp 100 includes an elastic frame 10, a first clamping piece 20, a second clamping piece 30, and a locking member 40.

[0023] Specifically, the elastic frame 10 includes a body portion 11, a first connecting end 12, and a second connecting end 13. The first connecting end 12 and the second connecting end 13 are respectively disposed at both ends of the body portion 11. Both the first connecting end 12 and the second connecting end 13 are bent in a direction away from the body portion 11, and are arranged opposite to each other. The elastic frame 10 is made of an elastic material, such as steel, and is used to provide an initial elastic clamping force. It is understood that the first connecting end 12 and the second connecting end 13 are arranged opposite to each other.

[0024] The first clamping piece 20 is connected to the first connecting end 12, and the second clamping piece 30 is connected to the second connecting end 13 and is disposed opposite to the first clamping piece 20, with the second clamping piece 30 and the first clamping piece 20 being parallel to each other. Both the first clamping piece 20 and the second clamping piece 30 can be made of steel or similar materials. The first clamping piece 20 and the second clamping piece 30 have a generally plate-like structure, which can stably contact the surface of the object, thereby improving the stability when clamping the object. The first clamping piece 20 can be fixedly connected to the first connecting end 12 by welding or other methods. It can be understood that the first connecting end 12 is connected to the side of the first clamping piece 20 away from the second clamping piece 30, so the non-connected portion of the first clamping piece 20 can undergo adaptive deformation when clamping the object, thereby improving the stability when clamping the object. The second clamping piece 30 can also be connected to the second connecting end 13 by welding or other methods.

[0025] The locking member 40 is movably inserted into the first connecting end 12, and the locking member 40 abuts against the side of the first clamping piece 20 away from the second clamping piece 30. The locking member 40 and the first connecting end 12 can be connected by means of threaded connection or other means, so that by rotating the locking member 40, the locking member 40 can be driven to move closer to or away from the first clamping piece 20.

[0026] The first clamping piece 20 and the second clamping piece 30 cooperate with each other to clamp the object, and the locking member 40 is configured to push the first clamping piece 20 toward the second clamping piece 30 to clamp the object.

[0027] The clamp 100 provided in this embodiment provides elasticity through an elastic frame 10. A first clamping piece 20 and a second clamping piece 30 are respectively connected to the first connecting end 12 and the second connecting end 13 of the elastic frame 10. When clamping an object, both the first clamping piece 20 and the second clamping piece 30 abut against the object, thus effectively improving clamping stability. The elasticity provided by the elastic frame 10 drives the first clamping piece 20 and the second clamping piece 30 to clamp the object. The locking member 40 pushes the first clamping piece 20 towards the object, increasing the clamping force and improving the clamping effect. The clamp 100 described above has a simple structure. In use, simply abut the first clamping piece 20 and the second clamping piece 30 against the object and tighten the locking member 40; it is easy to operate and provides good clamping effect.

[0028] In some embodiments, see Figure 1 and Figure 2 One side of the first clamping piece 20 is connected to the first connecting end 12, and the other side of the first clamping piece 20 extends toward the body part 11. One side of the second clamping piece 30 is connected to the second connecting end 13, and the other side of the second clamping piece 30 extends away from the body part 11. Since the first clamping piece 20 and the second clamping piece 30 extend in opposite directions (the first clamping piece 20 extends inward, and the second clamping piece 30 extends outward), they form an interlaced support structure, which makes the object subject to a more balanced constraint force when clamped, reducing deflection or slippage caused by unilateral force. The first clamping piece 20 extends toward the body part 11, which facilitates the locking member 40 to abut against the first clamping piece 20 after being connected to the first connecting end 12. During processing, the corresponding hole can be directly machined in the first connecting end 12 to install the locking member 40.

[0029] In some embodiments, see Figure 1 and Figure 2 The elastic skeleton 10 is a ring structure with an opening 14. The symmetrical bending characteristics of the ring structure with the opening 14 allow the elastic skeleton 10 to deform uniformly under stress, ensuring synchronous movement of the first connecting end 12 and the second connecting end 13 and avoiding stress concentration on one side. The ring structure with the opening 14 can be integrally stamped or wire bent, eliminating the need for complex welding or assembly, making it suitable for mass production. The natural concave space of the ring structure with the opening 14 provides more accommodating space for the object and the first clamping piece 20, making it particularly suitable for clamping objects with bosses or irregular contours.

[0030] In some embodiments, see Figure 1 and Figure 2The clamp 100 also includes a shim 50, which is disposed between the first clamping piece 20 and the second clamping piece 30. One side of the shim 50 is configured to abut against an object, and the other side is configured to abut against either the first clamping piece 20 or the second clamping piece 30. The structure of the shim 50 can be the same as that of the first clamping piece 20 and the second clamping piece 30. It is understood that when the thickness of the clamped object is less than the initial distance between the first clamping piece 20 and the second clamping piece 30, a shim 50 can be added between the first clamping piece 20 and the second clamping piece 30 so that the first clamping piece 20, the shim 50, and the second clamping piece 30 cooperate to clamp the object. Therefore, the number and position of the shims 50 can be set according to the actual situation. For example, when using one shim 50, the shim 50 can be disposed on one side of the first clamping piece 20 or one side of the second clamping piece 30. When using two shims 50, the two shims 50 can be respectively set on one side of the first clamping piece 20 and one side of the second clamping piece 30, or simultaneously set on one side of the first clamping piece 20 or one side of the second clamping piece 30. The shims 50 can be made of elastic materials, such as rubber. In this way, by setting the shims 50, the first clamping piece 20 and the second clamping piece 30 can be prevented from directly contacting the surface of the object, thus preventing scratches, indentations, or deformation. The thickness of the shims 50 can also be set according to actual needs. By replacing shims 50 of different thicknesses, the clamping gap can be flexibly adjusted, expanding the applicability of the clamp 100. It can adapt to objects of various sizes without modifying the main structure of the clamp 100.

[0031] In some embodiments, see Figure 1 The system comprises multiple elastic skeletons 10, which are arranged sequentially at intervals. The first connecting end 12 of each elastic skeleton 10 is connected to the first clamping piece 20, and the second connecting end 13 of each elastic skeleton 10 is connected to the second clamping piece 30. The number of elastic skeletons 10 can be two, three, four, etc. Multiple elastic skeletons 10 share the load, providing a greater overall clamping force, suitable for clamping wider, heavier, or more rigid objects.

[0032] In some embodiments, see Figure 1 Multiple locking elements 40 are provided, each corresponding to a first connecting end 12 of a plurality of elastic frames 10, and each locking element 40 abuts against a first clamping piece 20. It can be understood that the number of locking elements 40 is consistent with the number of elastic frames 10, with each locking element 40 mounted on one elastic frame 10. By providing multiple locking elements 40, the clamping and locking effect can be improved. Each locking element 40 can independently adjust the clamping force of its corresponding elastic frame 10, adapting to the force requirements of different parts of the object.

[0033] In some embodiments, see Figure 1Both the first clamping piece 20 and the second clamping piece 30 have anti-slip surfaces 31 on their respective sides, which are used to abut against the object. The anti-slip surfaces 31 increase the friction between the first and second clamping pieces 20 and the object, effectively resisting radial sliding and circumferential rotation of the object during clamping, preventing slippage, and further improving clamping stability.

[0034] In some embodiments, see Figure 1 and Figure 2 The clamp 100 also includes a first flexible member 60 and a second flexible member 70. The first flexible member 60 is disposed on the side of the first clamping piece 20 facing the second clamping piece 30, and the second flexible member 70 is disposed on the side of the second clamping piece 30 facing the first clamping piece 20. Both the first flexible member 60 and the second flexible member 70 are used to flexibly abut against the object. The first flexible member 60 and the second flexible member 70 can be made of rubber, silicone, high-density foam, etc. The first flexible member 60 and the second flexible member 70 can provide a soft contact surface, avoiding direct hard contact between the first clamping piece 20 and the second clamping piece 30 and the object, thereby reducing scratches, indentations or other mechanical damage to the surface of the object. The first flexible member 60 and the second flexible member 70 can better conform to the shape of the object, especially for objects with irregular or curved surfaces, providing a more uniform clamping force, reducing local stress concentration, and further protecting the surface of the object. The first flexible member 60 and the second flexible member 70 can increase the friction between the first clamping piece 20 and the second clamping piece 30 and the object, further improving the clamping stability. Even if the object surface is smooth, the first flexible member 60 and the second flexible member 70 can provide a reliable clamping effect.

[0035] In some embodiments, see Figure 1 and Figure 2 The locking member 40 includes a connecting portion 41 and a screwing portion 42 connected together. The connecting portion 41 is connected to the first connecting end 12, and the screwing portion 42 is located at the end of the connecting portion 41 away from the first clamping piece 20. The screwing portion 42 is used to drive the connecting portion 41 to move toward or away from the first clamping piece 20 under the action of external force. The connecting portion 41 of the locking member 40 can be connected to the first connecting end 12 by a threaded connection. The screwing portion 42 is generally a plate-like structure. By rotating the screwing portion 42, the connecting portion 41 can be driven to rotate, thereby driving the connecting portion 41 to abut against or move away from the first clamping piece 20. In this embodiment, the locking member 40 can be a rabbit head bolt, etc. By setting the screwing portion 42, the operation of the clamp 100 is more intuitive and simple. The operator only needs to complete the adjustment of the clamping force by a simple rotation action, without complicated tools or complicated operation steps, which greatly improves work efficiency.

[0036] In some embodiments, see Figure 1 and Figure 2 The thickness of the body portion 11 is greater than the thickness of the first connecting end 12 and the second connecting end 13. In this embodiment, the thickness of the elastic skeleton 10 gradually decreases from the body portion 11 towards the first connecting end 12 and the second connecting end 13. By thickening the main load-bearing area of ​​the body portion 11, the overall bending stiffness of the elastic skeleton 10 is significantly improved, avoiding excessive elastic deformation during locking. The thinner first connecting end 12 and the second connecting end 13 can maintain the necessary flexibility, ensuring that the first clamping piece 20 and the second clamping piece 30 can generate sufficient elastic displacement. The thickened design of the body portion 11 can reduce the fatigue risk under cyclic loads, and the thickness transition area can be treated with rounded corners to effectively avoid stress concentration that could cause cracks in the elastic skeleton 10 during use.

[0037] The working process of the fixture 100 provided in this embodiment is roughly as follows:

[0038] When clamping an object, the first clamping piece 20 and the second clamping piece 30 of the clamp 100 are placed on both sides of the object to be clamped. If the distance between the first clamping piece 20 and the second clamping piece 30 is greater than the thickness of the object, a shim 50 is added between the first clamping piece 20 and the second clamping piece 30 until the elastic frame 10 drives the first clamping piece 20, the shim 50 and the second clamping piece 30 to clamp the object through elastic force. Then, the connecting part 41 is driven to rotate by the screwing part 42 of the locking member 40 until the connecting part 41 pushes against the first clamping piece 20 to clamp the object.

[0039] When releasing the object, rotate the locking member 40 in the opposite direction to move the locking member 40 away from the first clamping piece 20, and then remove the clamp 100 from the object.
