Description

Technical Field This utility model relates to the field of cyclone clamp technology, and in particular to a wear-resistant cyclone clamp with adjustable tightness. Background Technology A cyclone clamp, also known as a cyclone clamping device or cyclone jig, refers to a device that uses rotational motion to fix or clamp a workpiece. This device is commonly used in machining, assembly, or experimental operations to provide a stable clamping force, ensuring the workpiece remains in a fixed position during processing. For example, a cyclone clamp can be used to clamp the crossbar of a bicycle. Currently, cyclone clamps typically have a single model and size that can only accommodate one type of workpiece, and cannot provide a stable clamping force for workpieces of multiple sizes and shapes simultaneously, resulting in a limited range of applications.

[0001] A prior patent application with application number CN 2024203232584 discloses an adjustable tension cyclone clamp. It drives a threaded cam to rotate by rotating a rotating base, which in turn drives a pair of gears to rotate, achieving the effect of winding or unwinding a cable from a rotating shaft. The length of the cable extending beyond the lower fixed base is adjustable. Based on the flexibility of the cable itself, it can adapt to workpieces of different sizes and shapes, improving the applicability of the clamp. In practical applications, to ensure the tensile strength of the cable to meet stronger tensile force requirements, the cable is designed as a metal sheet covered with a layer of braided tape, and a large metal card is provided at one end of the cable as a detachable locking device for connection with a slot. However, in conjunction with the appendix of this prior application… Figure 2 As shown, a right-angle structure is formed between the card and the edge of the cable strip. After prolonged engagement and continuous pulling, this right-angle structure may cut through the card slot, causing one end of the cable strip to become unable to engage. However, if the edge of the metal card and the cable strip is designed as a beveled transition, the connection strength of the metal card when engaged in the card slot will be reduced.

[0002] Therefore, it is necessary to provide a wear-resistant and adjustable cyclone clamp to overcome the above-mentioned defects. Utility Model Content The purpose of this invention is to provide a wear-resistant and adjustable cyclone clamp, which aims to solve the problem that the clamping parts of the adjustable cyclone clamp are prone to cracking of the clamping slot or insufficient clamping strength after long-term use.

[0003] To achieve the above objectives, this utility model provides a wear-resistant and adjustable tightness cyclone clamp, comprising: The lower fixed base is provided with a wire gathering wheel, and the wire gathering wheel is wound with a wire strip that can extend out of the lower fixed base; the wire gathering wheel includes a winding post, a pair of gears respectively provided on both sides of the winding post, and two rotating shafts provided on the side of the pair of gears that are far apart from each other, and the wire strip is wound around the winding post; The upper fixed seat includes a cover plate and a pair of opposing limiting strips disposed on the side of the cover plate near the lower fixed seat; the two rotating shafts are respectively rotatably connected to the two limiting strips; A rotating base is sleeved on the outside of the limiting strip and pressed onto the lower fixed base by the cover plate. The inner side of the rotating base is provided with a threaded protrusion that extends into the space between adjacent teeth of the gear. One end of the cable strip is provided with a cylindrical locking block, and both ends of the locking block protrude from the cable strip along its width direction. The lower fixing base has a through hole for the cable strip to pass through. The outer side of the lower fixing base is also provided with a locking groove for engaging the locking block. The locking groove includes a first limiting groove adapted to the locking block and a second limiting groove communicating with the first limiting groove. The side wall of the first limiting groove has a through hole for the cable strip to pass through, so that after the locking block is inserted into the first limiting groove, the cable strip can pass through the through hole and rotate into the second limiting groove. The second limiting groove is used to limit the movement of the cable strip along its width direction.

[0004] In a preferred embodiment, the cover plate, the rotating seat, and the lower fixed seat together form a receiving cavity, the limiting strip and the wire gathering wheel are both disposed in the receiving cavity, and the through hole communicates with the receiving cavity.

[0005] In a preferred embodiment, one of the gears is provided with at least one connecting post; the connecting post is located inside the winding post and has a threaded hole; the other gear has a locking hole adapted to the connecting post, the locking hole and the threaded hole are connected by a locking screw to clamp the winding post between the two gears.

[0006] In a preferred embodiment, a wire-passing gap is provided at a preset position of the winding post, and one of the gears is provided with a clamping block at a position corresponding to the inside of the winding post; one end of the wire strip passes through the wire-passing gap and extends into the winding post, and is clamped by the clamping block.

[0007] In a preferred embodiment, a torsion block is provided at a predetermined position on the outer side of the rotary seat.

[0008] In a preferred embodiment, the lower fixing seat is provided with a first protective block, the upper fixing seat is provided with a second protective block, and a receiving hole is provided between the first protective block and the second protective block.

[0012] In a preferred embodiment, the arcuate surface of the lower fixed seat is provided with a friction-enhancing portion.

[0013] This utility model provides a wear-resistant and adjustable tension cyclone clamp. It features a cylindrical locking block at one end of the cable and a locking groove on the lower fixed base, forming a T-shaped structure with the cable. In use, the locking block is axially inserted into the first limiting groove, at which point the cable simultaneously passes through the through hole. Once the locking block is fully inserted into the first limiting groove, the cable is rotated to the second limiting groove using the locking block as a pivot. At this point, the area where the locking block presses against the locking groove distributes the tension on the cable. The stress area is no longer limited to the connection between the locking block and the cable, and the locking block and the locking groove have a surface contact connection, resulting in a larger overall stress-bearing area. This allows the cable to withstand greater tension and reduces the likelihood of damage to the locking groove, thus extending the service life of the cyclone clamp.

It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0016] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0017] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0018] In an embodiment of this utility model, a wear-resistant and adjustable cyclone clamp 100 is provided to provide clamping force for round, square or other irregularly shaped workpieces. The tightness can be adjusted according to different models and sizes, so as to adapt to workpieces of different models and sizes.

[0019] like Figures 1-7As shown, the wear-resistant and adjustable cyclone clamp 100 includes: a lower fixed seat 10, an upper fixed seat 20, and a rotating seat 30.

[0020] The lower fixed base 10 is provided with a wire feeder 40. The wire feeder 40 is wound with a wire strip 50 that can extend out of the lower fixed base 10. The lower fixed base 10 has a through hole 101 for the wire strip 50 to pass through. When clamping is required, the wire strip 50 can be pulled out from the lower fixed base 10 through the through hole 101, and then one end of the wire strip 50 can be clamped into the clamping groove 102, thereby completing the sealing of the workpiece.

[0021] Specifically, the coil spool 40 includes a winding post 41, a pair of gears 42 respectively disposed on both sides of the winding post 41, and two rotating shafts 43 disposed on opposite sides of the pair of gears 42. The winding post 41 is cylindrical, and the two gears 42 are symmetrically and coaxially disposed at both ends of the winding post 41. The cable 50 is wound around the winding post 41, so the cable 50 can be wound or unwound by rotating the winding post 41.

[0022] One end of the cable strip 50 is provided with a cylindrical locking block 51. The outer side of the lower fixing base 10 is also provided with a locking groove 102 for engaging the locking block 51. Both ends of the locking block 51 protrude from the cable strip 50 along its width direction, forming a T-shaped structure together with the cable strip 50. Furthermore, at least one fixing post 52 is embedded within the locking block 51, with its center perpendicularly passing through one end of the cable strip 50, thereby enhancing the connection strength between the locking block 51 and the cable strip 50. Additionally, it also ensures a stable connection between the plastic locking block 51 and the metal cable strip 50.

[0023] The slot 102 includes a first limiting slot 1021 adapted to the locking block 51 and a second limiting slot 1022 communicating with the first limiting slot 1021. The first limiting slot 1021 can be a cylindrical slot, and the second limiting slot 1022 can be a right-angled U-shaped slot. The central axis of the first limiting slot 1021 and the central axis of the second limiting slot 1022 form a T-shape. The side wall of the first limiting slot 1021 has a through hole 1023 for the cable strip 50 to pass through, so that when the locking block 51 is inserted into the first limiting slot 1021 axially, the cable strip 50 can pass through the through hole 1023 and move accordingly. The through hole 1023 plays a clearance role. Then the cable strip 50 can rotate the locking block 51 as a rotating axis into the second limiting slot 1022. The second limiting slot 1022 is used to limit the movement of the cable strip 50 along its width direction, thereby preventing the cable strip 50 from moving along its width direction, that is, preventing the locking block 51 from moving axially.

[0024] Therefore, the part of the card block 51 that is pressed into the card slot 102 shares the tensile force on the cable 50. The force-bearing area is no longer limited to the connection between the card block 51 and the cable 50. Moreover, the card block 51 and the card slot 102 are in surface contact connection, so the overall force-bearing area is larger. The cable 50 can withstand greater tensile force and is less likely to damage the card slot 102.

[0025] Furthermore, one of the gears 42 is provided with at least one connecting post 44. The connecting post 44 is located within the area enclosed by the hollow winding post 41 and has a threaded hole 441. The other gear 42 has a locking hole 442 that matches the connecting post 44. The locking hole 442 and the threaded hole 441 are connected by a locking screw 45 to clamp and fix the winding post 41 between the two gears 42.

[0026] Furthermore, a wire-passing gap 411 is provided at a preset position of the winding post 41. One of the gears 42 is provided with a clamping block 46 at a corresponding internal position of the winding post 41. One end of the wire strip 50 passes through the wire-passing gap 411 and extends into the winding post 41, and is clamped by the clamping block 46, thereby making one end of the wire strip 50 more securely connected to the winding post 41.

[0027] In some embodiments, the side of the lower fixing seat 10 away from the upper fixing seat 20 is recessed inward to form an arc surface, thereby getting closer to the cylindrical workpiece and reducing slight vibrations that occur when the workpiece is clamped. Furthermore, the arc surface of the lower fixing seat 10 is provided with a friction-enhancing portion 11. The friction-enhancing portion 11 can be a textured layer provided on the inner side of the arc surface, or it can be a plurality of protrusions provided on the arc surface, such as a plurality of wavy strip-shaped protrusions, a matrix of protrusions, etc., which can increase the friction between the lower fixing seat 10 and the workpiece and prevent relative rotation between the two.

[0028] In this embodiment, the upper fixing seat 20 includes a cover plate 21 and a pair of opposing limiting strips 22 disposed on the side of the cover plate 21 near the lower fixing seat 10. Two rotating shafts 43 are rotatably connected to the two limiting strips 22 respectively. Further, the lower fixing seat 10 is provided with two support strips 12 that are adapted to the two limiting strips 22 respectively. The support strips 12 are aligned and abut against the corresponding limiting strips 22, and together they form a rotating hole 201 at the abutment position. For example, a semi-circular groove is opened at the end of the limiting strip 22, and another semi-circular groove is opened at the end of the support strip 12. The two semi-circular grooves together form the rotating hole 201. The two rotating shafts 43 are respectively inserted into the two rotating holes 201.

[0029] The rotating base 30 is sleeved on the outside of the limiting strip 22 and pressed onto the lower fixed base 10 by the cover plate 21. The inner side of the rotating base 30 is provided with a threaded protrusion 31, which extends between adjacent teeth of the gear 42. The cover plate 21, the rotating base 30, and the lower fixed base 10 together form a receiving cavity. The limiting strip 22 and the winding wheel 40 are both located within the receiving cavity. The through hole 101 communicates with the receiving cavity. When the rotating base 30 rotates, the threaded protrusion 31 rotates synchronously with the central axis of the thread, changing the contact position between the threaded protrusion 31 and the gear 42, thereby driving the gear 42 to rotate around the linear axis 43, and consequently causing the winding post 41 to rotate synchronously.

[0030] In one embodiment, the lower fixing seat 10 is provided with a first protective block 13, and the upper fixing seat 20 is provided with a second protective block 23. The first protective block 13 and the second protective block 23 are provided with a receiving hole 202. The winding post 41 is coaxially disposed in the receiving hole 202 so that the wire 50 is wound between the surface of the winding post 41 and the inner wall of the receiving hole 202, thereby preventing the wire 50 from spreading out in the receiving cavity.

[0031] In one embodiment, a torsion block 32 is provided at a preset position on the outer side of the rotary base 30. The torsion block 32 is a protruding structure extending from the surface of the rotary base 30. In this embodiment, there is a pair of torsion blocks 32, which are respectively provided on opposite sides of the rotary base 30, so as to facilitate the user to rotate the rotary base 30 by gripping the torsion block 32.

[0032] In summary, the wear-resistant and adjustable tension cyclone clamp 100 provided by this utility model features a cylindrical locking block 51 at one end of the cable 50 and a locking groove 102 on the lower fixed base 10, forming a T-shaped structure with the cable 50. In use, the locking block 51 can be axially inserted into the first limiting groove 1021, at which point the cable 50 simultaneously passes through the through hole 1023. After the locking block 51 is fully inserted into the first limiting groove 1021, the cable 50 is rotated to the second limiting groove 1022 using the locking block 51 as a rotating axis. At this point, the portion of the locking block 51 pressed against the locking groove 102 shares the tension on the cable 50, and the stress area is no longer limited to the connection between the locking block 51 and the cable 50. Furthermore, the locking block 51 and the locking groove 102 are in surface contact, resulting in a larger overall stress-bearing area. This allows the cable 50 to withstand greater tension and reduces the likelihood of damage to the locking groove 102, thus extending the service life of the cyclone clamp.

[0033] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
