DETAILED DESCRIPTION

[0078] In view of this, the present invention provides a clamp that can lock components that need to be connected, such as tank doors and flanges with larger areas, so that it is more suitable for practical use.

[0079] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of a clamp proposed according to the present invention, its specific implementation, structure, features and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0080] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B. Specifically, it is understood that: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may be met.

[0081] See attached Figure 1 -Attached Fig. 9The clamp provided by the present invention includes a linear force-applying mechanism and a clamp. The linear force-applying mechanism has a first free end; the first free end corresponds to the setting position of the clamp; when the object to be clamped is between the first free end and the clamp and needs to be clamped, the first free end is driven by the linear force-applying mechanism to approach the clamp, so that the distance between the first free end and the clamp is reduced, and the object to be clamped is clamped.

[0082] The clamp provided by the present invention utilizes a linear force-applying mechanism to drive the linear movement of the first free end. When the first free end is driven by the linear force-applying mechanism and approaches the chuck, the distance between the first free end and the chuck is reduced, thereby achieving clamping of the object to be clamped. When the clamped object needs to be released from the clamping state, the linear force-applying mechanism drives the first free end to move in a direction away from the chuck, thereby releasing the clamping state of the object to be clamped.

[0083] The linear force mechanism includes a linear force driver 1 and a clamping rod 14. The clamping rod 14 forms a moving pair with the linear force driver 1 through one end thereof, and the other end of the clamping rod 14 forms a first free end. The linear force driver 1 is used to clamp the clamping rod 14. In this case, driven by the linear force driver 1, the clamping rod 14 can perform linear reciprocating motion. When the clamping rod 14 approaches the chuck, the object to be clamped is clamped due to the reduction of the physical distance between the clamping rod 14 and the chuck; when the clamping rod 14 leaves the chuck, the object to be clamped is released from the clamping state due to the increase of the physical distance between the clamping rod 14 and the chuck.

An accommodating space is formed between the first connecting member 5, the fourth connecting member 3 and the fifth connecting member 8, one end of the chuck is arranged in the accommodating space, and the other end of the chuck corresponds to the position of the first free end. In this case, the setting position of the chuck is determined, so the connection is stable and reliable.

[0087] The clamp further includes a limit plate 4. The limit plate 4 is fixedly connected to the fourth connecting member 3 and the fifth connecting member 8 at the same time, and an accommodation space is formed between the first connecting member 5, the fourth connecting member 3, the fifth connecting member 8 and the limit plate 4. In this case, the setting position of the clamp is more certain, so the connection is more stable and reliable.

[0088] The clamp provided in the embodiment of the present invention further includes a connecting mechanism. The connecting mechanism provides a connecting sub-end, one end of the chuck provides a connecting female end, and the chuck is detachably connected to the sub-end of the connecting mechanism through the female end.

In this case, the first connecting sub-end and the second connecting sub-end with reliable connection and limiting can be provided, so that the connection between the chuck and the connecting mechanism is more convenient.

[0090] Among them, the clamp provided by the embodiment of the present invention also includes a first connecting seat 23, a second connecting seat 24, a third limiting member 43 and a fourth limiting member 20. The clamping rod 14 passes through the first connecting seat 23, the second connecting seat 24, the third limiting member 43, the connecting block 19 and the fourth limiting member 20 from bottom to top, so that the clamping rod 14 and the first connecting seat 23, the second connecting seat 24, the third limiting member 43, the connecting block 19 and the fourth limiting member 20 all form a moving pair. In this case, the clamping rod 14 passes through the first connecting seat 23, the second connecting seat 24, the third limiting member 43, the connecting block 19 and the fourth limiting member 20 from bottom to top, which can not only provide linear limitation for the clamping rod 14, but also ensure the stability of the first connecting sub-end and the second connecting sub-end, thereby ensuring that the connecting block 19 is still stable after the clamp is disassembled and assembled for many times.

[0091] The chuck includes a first side plate 9, a second side plate 10, a first connecting plate 2, a clamping plate 16, a pin 41, a first limit pin 40 and a second limit pin 43. One end of the first side plate 9 is bent to form a first bent end 17, and one end of the second side plate 10 is bent to form a second bent end 18. The positions of the first bent end 17 and the second bent end 18 correspond to each other. One end of the clamping plate 16 is fixedly connected to one side of the first bent end 17, and the other end of the clamping plate 16 is fixedly connected to one side of the second bent end 18.

The other side of the second side plate 10 is provided with a second opening 31, so that the fifth free end 29 formed by the second side plate 10 is in a second hook shape, so as to obtain a second connecting female end. The first side plate 9 is provided with a There is a first pin hole 32, and a second pin hole 33 is provided on the second side plate 10, and the setting positions of the first pin hole 32 and the second pin hole 33 correspond to each other; a first guide limit hole 37 is provided on the fourth connecting member 3, and a second guide limit hole 38 is provided on the fifth connecting member 8, and the setting positions of the first guide limit hole 37 and the second guide limit hole 38 correspond to each other; when the chuck is respectively connected to the first connecting sub-end and the second connecting sub-end through the first connecting female end and the second connecting female end, after the pin shaft 41 passes through the first pin hole 32, the second pin hole 33, the first guide limit hole 37, and the second guide limit hole 38 at the same time, a first remainder and a second remainder are left on the outer sides of the fourth connecting member 3 and the fifth connecting member 8 respectively; the first limit pin 40 is penetrated in the first remainder, and the second limit pin 43 is penetrated in the second remainder. In this case, the pin shaft 41 can ensure that even if the chuck is removed from the first connecting sub-end and the second connecting sub-end, the chuck is still connected to other parts of the clamp, which can prevent the chuck from falling off or being lost due to separation from the first connecting sub-end and the second connecting sub-end.

[0092] The opening side dimension of the first opening 30 is larger than the closing side dimension of the first opening 30. The opening side dimension of the second opening 31 is larger than the closing side dimension of the second opening 31. In this case, since the opening side dimension of the first opening 30 is larger, the first connector end can be more easily inserted into the first opening 30; since the opening side dimension of the second opening 31 is larger, the second connector end can be more easily inserted into the second opening 31, and the assembly and disassembly of the chuck is more convenient.

[0093] The opening direction of the first opening 30 is inclined from the opening side to the vertex of the first hook. The opening direction of the second opening 31 is inclined from the opening side to the vertex of the second hook. In this case, since the chuck is subjected to a linear force when in use, and the directions of the first opening 30 and the second opening 31 are inclined, that is, the opening directions of the first opening 30 and the second opening 31 are not parallel to the force direction thereof, thus preventing the chuck from falling off due to force during use.

[0094] The clamp provided in the embodiment of the present invention further includes a second connecting plate 13. The other side edges corresponding to the first side plate 9 and the second side plate 10 are connected together by the second connecting plate 13. In this case, the first side plate 9 and the second side plate 10 are connected together by the first connecting plate 2 and the second connecting plate 13, so that the connection stability of the first side plate 9 and the second side plate 10 can be ensured.

[0095] The clamp further includes a third connecting plate 25. One end of the third connecting plate 25 is fixedly connected to the other side of the first bent end 17, and the other end of the third connecting plate 25 is fixedly connected to the other side of the second bent end 18. In this case, the first bent end 17 and the second bent end 18 are also fixedly connected together on the outer side of the clamping plate 16 by the third connecting plate 25, which can further ensure the connection stability of the first side plate 9, the second side plate 10, and the clamping plate 16.

[0096] The first side plate 9 is provided with a first flange 26 at a position corresponding to the fourth free end 28. The second side plate 10 is provided with a second flange 27 at a position corresponding to the fifth free end 29. In this case, the first flange 26 and the second flange 27 can increase the area at the first opening 30 and the second opening 31, thereby enhancing the connection strength of the first side plate 9 and the second side plate 10.
