Description

[Technical field]

[0001] The utility model relates to the technical field of cyclone clamps, in particular to a cyclone clamp with adjustable tightness. [Background technology]

[0002] A cyclone clamp, also known as a cyclone clamp or cyclone fixture, refers to a device that uses a rotating motion to fix or clamp a workpiece. This device is often used in machining, assembly, or experimental operations to provide a stable clamping force to ensure that the workpiece is fixed in position during the machining process. For example, a cyclone clamp can be clamped on the crossbar of a bicycle. However, current cyclone clamps usually only fit one workpiece in one size and cannot provide a stable clamping force for workpieces of multiple sizes and shapes at the same time, resulting in a small range of applications.

[0003] In view of this, it is necessary to provide a cyclone clamp with adjustable tightness to overcome the above-mentioned defects. [Utility Model Content]

[Specific implementation method]

[0024] In order to make the purpose, technical solution and beneficial technical effect of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0025] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0026] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0027] In an embodiment of the utility model, a cyclone clamp 100 with adjustable tightness is provided, which is used to provide clamping force for round, square or other irregularly shaped workpieces. Different tightness can be adjusted according to different models and sizes, so that it can adapt to workpieces of different models and sizes.

[0028] like Figure 1-Figure 4 As shown, the tightness-adjustable cyclone clamp 100 comprises a lower fixing base 10 , an upper fixing base 20 and a rotating base 30 .

[0029] Specifically, the lower fixed seat 10 is provided with a wire collecting wheel 40. The wire collecting wheel 40 is wound with a wire belt 50 that can extend out of the lower fixed seat 10, and the lower fixed seat 10 is provided with a through hole 101 for the wire belt 50 to pass through. The outer side of the lower fixed seat 10 is also provided with a slot 102 for clamping one end of the wire belt 50. Therefore, when a clamping action is required, the wire belt 50 can be pulled out from the lower fixed seat 10, and then one end of the wire belt 50 can be clamped in the slot 102, thereby completing the closure of the workpiece. It can be understood that one end of the wire belt 50 is provided with a clamping head structure that can be clamped in the slot 102. Reference can be made to the prior art here and no further description is given here. Therefore, for workpieces of different models and sizes, different lengths of the wire belt 50 can be pulled out accordingly.

[0030] The line collecting wheel 40 includes a rotating shaft 41 and a pair of gears 42 respectively disposed on both sides of the rotating shaft 41. The line belt 50 is wound around the rotating shaft 41 between the pair of gears 42. Therefore, the rotating shaft 41 can be driven to rotate around its own central axis by rotating the driving gear 42, so as to realize the winding or unwinding of the line belt 50 in the middle of the rotating shaft 41, and then adjust the length of the line belt 50 extending out of the lower fixing seat 10.

[0031] Furthermore, the side of the lower fixed seat 10 away from the upper fixed seat 20 is recessed inward to form an arc surface, so that it can be closer to the cylindrical workpiece and reduce the slight vibration of the workpiece when it is clamped. Furthermore, the arc surface of the lower fixed seat 10 is provided with a friction-increasing portion 11. The friction-increasing portion 11 can be a texture layer arranged on the inner side of the arc surface, or it can be a plurality of protrusions arranged on the arc surface, such as a plurality of wavy strip protrusions, a protrusion matrix, etc., so that the friction between the lower fixed seat 10 and the workpiece can be increased to prevent the two from rotating relative to each other.

[0032] In the embodiment of the utility model, the upper fixing seat 20 includes a cover plate 21 and a pair of oppositely disposed limiting bars 22 disposed on the side of the cover plate 21 close to the lower fixing seat 10. That is, the pair of limiting bars 22 are oppositely disposed and are respectively vertically disposed on both sides of the cover plate 21. Each limiting bar 22 is provided with a rotating hole 221, and both ends of the rotating shaft 41 are respectively penetrated in the rotating holes 221, so that the pair of gears 42 can rotate around the rotating shaft 41 between the pair of limiting bars 22.

[0033] The rotating seat 30 is sleeved on the outer side of the limiting strips 22 and is pressed onto the lower fixing seat 10 by the cover plate 21, so that the rotating seat 30 can rotate around a pair of limiting strips 22 and will not be separated from the lower fixing seat 10. Figure 5As shown, a thread convex strip 31 is provided on the inner side of the rotating seat 30. The thread convex strip 31 is designed along the thread line, includes at least one circle, and extends into the portion between adjacent teeth of the gear 42. Therefore, when the rotating seat 30 rotates, the thread convex strip 31 will rotate synchronously with the central axis of the thread to change the abutment position between the thread convex strip 31 and the gear 42, thereby driving the gear 42 to rotate around the rotating shaft 41, and then driving the rotating shaft 41 to rotate synchronously.

[0034] Furthermore, a twist block 32 is provided at a preset position outside the rotating seat 30. The twist block 32 is a protruding structure extending from the surface of the rotating seat 30. In this embodiment, the number of the twist blocks 32 is a pair, which are respectively provided on opposite sides of the rotating seat 30, so that the user can rotate the rotating seat 30 by grasping the twist blocks 32.

[0035] It should be noted that the cover plate 21 , the rotating seat 30 and the lower fixing seat 10 are jointly arranged to form a receiving cavity, and the limiting strip 22 and the cable collection wheel 40 are both arranged in the receiving cavity.

[0036] Combination Figure 3 As shown, a first protective block 12 is provided in the lower fixed seat 10, a second protective block 13 is provided between a pair of gears 42, and a receiving hole 103 is provided between the first protective block 12 and the second protective block 13. The wire belt 50 wound around the rotating shaft 41 is located in the receiving hole 103, that is, the wire belt 50 is protected in the receiving hole 103 to prevent other components from causing damage to the wire belt 50.

[0037] Furthermore, a positioning column 23 is provided at one end of the limiting strip 22 away from the cover plate 21, and a positioning groove (not shown in the figure) is provided in the lower fixing seat 10, and the positioning column 23 can move up and down in the positioning groove. Therefore, the positioning column 23 cooperates with the positioning groove to limit the direction in which the rotating seat 30 drives the upper fixing seat 20 to move, so as to improve the connection accuracy between the upper fixing seat 20 and the lower fixing seat 10.

[0038] Furthermore, a screw rod 24 is provided on one side of the upper fixing seat 20 away from the lower fixing seat 10 . The screw rod 24 extends into the receiving cavity and can abut against the second protection block 13 , thereby limiting the position of the second protection block 13 in the receiving cavity.

[0039] To summarize, the cyclone clamp 100 with adjustable tightness provided by the utility model can drive the threaded ridge 31 to rotate by rotating the rotating seat 30 through the relative position relationship between the threaded ridge 31 and the gear 42, thereby driving a pair of gears 42 to rotate, thereby achieving the effect of winding or loosening the wire band 50 from the rotating shaft 41, and adjusting the length of the wire band 50 extending out of the lower fixed seat 10. Based on the flexibility of the wire band 50 itself, it can adapt to workpieces to be clamped of different sizes and shapes, thereby improving the scope of application of the clamp.

[0040] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
