Description

Technical Field

[0001] This utility model relates to the field of button processing technology, specifically to a button clamp that prevents buttons from slipping off. Background Technology

[0002] Buttons are small accessories used to fasten clothing. They are fastened by passing through buttonholes in the garment and are widely used in clothing. When processing or removing a single button, a clamp is needed to hold and fix the button in place.

[0003] Chinese patent (publication number: CN118785829A) discloses a button removal clamp capable of disassembling a button mounted on fabric into multiple parts. This invention relates to a button removal clamp for removing a button, consisting of multiple parts, from fabric while it is mounted on the fabric using a fixing member. The clamp includes: a base; a pressure receiving portion disposed above the base, which receives pressure and descends from an initial position; a separating plate disposed below the base, which rises and falls together with the pressure receiving portion; and a deformation-imposing portion extending downward from the pressure receiving portion for deforming the button. The base includes a first button receiving portion for receiving the button. The separating plate includes a second button receiving portion disposed at a position corresponding to the first button receiving portion.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: when performing non-destructive disassembly of damaged or replaceable buttons, special clamps are required to accurately clamp and position the button components to prevent damage to the fabric substrate during the application of disassembly force. Current clamping devices have significant limitations in terms of clamping compatibility with buttons of various sizes. Utility Model Content

[0005] The purpose of this utility model is to provide a button clamp that prevents button slippage, so as to solve the problem that the existing clamping devices in the background art have obvious limitations in terms of clamping compatibility with buttons of various specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a button clamp for preventing detachment, comprising a mounting frame, wherein three radially distributed guide rods are fixedly connected to the top of the mounting frame, and the ends of the three guide rods are connected to each other;

[0007] A clamping block is slidably connected to the outside of the guide rod. A turntable is rotatably connected between the top of the mounting bracket and the bottom of the guide rod. The turntable has an arc-shaped guide groove inside and anti-slip texture on the outside. A guide rod that slides inside the guide groove is fixedly connected to the bottom of the clamping block.

[0008] Preferably, the clamping block has a guide hole in the middle, and the clamping block is slidably sleeved on the outside of the guide rod through the guide hole.

[0009] Preferably, the upper end of the clamping block is bent inward vertically to form a bent portion, and the top of the clamping block is provided with a reserved inclined surface, which extends downward from the outside of the clamping block inward.

[0010] Preferably, a rotating shaft is fixedly connected to the middle of the turntable, and the upper end of the rotating shaft is rotatably connected to the end connection of three guide rods through a bearing, and the lower end of the rotating shaft is rotatably connected to the middle of the mounting frame through a bearing.

[0011] Preferably, the lower end of the rotating shaft passes through the middle of the mounting frame, and a torsion spring is sleeved on the outer side of the lower end of the rotating shaft. The two ends of the torsion spring are respectively fixedly connected to the rotating shaft and the bottom of the mounting frame.

[0012] Preferably, a mounting ring is fixedly connected to the bottom of the mounting bracket, and the outer wall of the mounting ring is threaded, and a mounting sleeve is fixedly connected to the top of the connection of the three guide rods.

[0013] Preferably, a support plate is slidably connected inside the mounting sleeve in the vertical direction, and a compression spring is fixedly connected between the bottom of the support plate and the bottom of the inner side of the mounting sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This anti-detachment button clamp uses a turntable to drive the rotation of the turntable, which in turn drives the radial movement of the clamping blocks through a specially designed arc-shaped guide groove. When the turntable rotates, the three sets of clamping blocks expand outward synchronously along the radial guide rod to form a clamping space. When rotated counterclockwise, the clamping blocks are driven to contract inward. The top bend and the support plate form upper and lower clamping planes, which facilitates the clamping and fixing of buttons of different sizes.

[0016] The elastic support system consists of a compression spring and a sliding support plate inside the mounting sleeve. It can automatically adapt to button specifications within a certain thickness range. The elastic displacement of the support plate effectively compensates for the button thickness tolerance while maintaining a constant clamping force. The torsion spring at the bottom of the rotating shaft provides an automatic reset function. After processing, the turntable is released, and the clamping block quickly resets to the initial closed state under the action of the spring torque, preventing accidental loosening due to vibration during processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: a button clamp for preventing detachment, comprising a mounting frame 1, three radially distributed guide rods 2 fixedly connected to the top of the mounting frame 1, and the ends of the three guide rods 2 being connected to each other; a clamping block 3 is slidably connected to the outside of the guide rods 2; a turntable 4 is rotatably connected between the top of the mounting frame 1 and the bottom of the guide rods 2; the turntable 4 has an arc-shaped guide groove 5 inside, and an anti-slip texture on the outside of the turntable 4; a guide rod 6 is fixedly connected to the bottom of the clamping block 3 and slides inside the guide groove 5; a guide hole 7 is provided in the middle of the clamping block 3, and the clamping block 3 is slidably sleeved on the outside of the guide rod 2 through the guide hole 7.

[0026] Preferably, the upper end of the clamping block 3 is bent inward vertically to form a bent part, and the top of the clamping block 3 is provided with a reserved inclined surface 8. The reserved inclined surface 8 extends downward from the outside of the clamping block 3 inward. The turntable 4 is fixedly connected to the rotating shaft 9. The upper end of the rotating shaft 9 is rotatably connected to the end connection of the three guide rods 2 through a bearing. The lower end of the rotating shaft 9 is rotatably connected to the middle of the mounting frame 1 through a bearing. The lower end of the rotating shaft 9 passes through the middle of the mounting frame 1. A torsion spring 10 is sleeved on the outer side of the lower end of the rotating shaft 9. The two ends of the torsion spring 10 are fixedly connected to the rotating shaft 9 and the bottom of the mounting frame 1, respectively. The bottom of the mounting frame 1 is fixedly connected to the bottom of the mounting frame 1. The outer wall of the mounting ring 11 is provided with threads. The top of the connection of the three guide rods 2 is fixedly connected to the mounting sleeve 12. The mounting sleeve 12 is slidably connected to the support plate 13 in the vertical direction. A compression spring 14 is fixedly connected between the bottom of the support plate 13 and the bottom of the inner side of the mounting sleeve 12.

[0027] The basic support frame is formed by the three radial guide rods 2 supported by the housing 1. The three guide rods 2, which are symmetrically distributed at 120°, meet at the top to form a stable triangular structure. The clamping block 3 forms a sliding structure with the guide rod 2 through its guide hole 7, ensuring that each clamping unit always maintains a radial movement trajectory. The turntable 4 is the core driving component. The arc-shaped guide groove 5 machined inside it and the guide rod 6 at the bottom of the clamping block 3 form a motion conversion mechanism. When the operator rotates the turntable 4 with anti-slip texture, the curvature change of the guide groove 5 forces the guide rod 6 to move, thereby driving the three clamping blocks 3 to move synchronously along the guide rod 2 in a centripetal or centrifugal motion.

[0028] The pre-reserved inclined surface 8 at the top of the clamping block 3 forms a guide and guide structure. When the button is pressed down, its edge contacts the inclined surface to generate a component force, which automatically corrects the center position of the button. At this time, the bottom surface of the button contacts the support plate 13 inside the mounting sleeve 12. The support plate 13 achieves vertical elastic support through the compression spring 14, forming a clamping mode of lower support and upper clamp. The upper and lower ends of the rotating shaft 9 are respectively connected to the intersection point of the guide rod 2 and the housing 1 through bearings to ensure that the turntable 4 rotates smoothly. The torsion spring 10 at the bottom of the rotating shaft 9 stores mechanical energy through pre-tightening force. When the external force is released, it drives the turntable 4 to reset, so that the clamping block 3 automatically tightens to the initial clamping position.

[0029] During the clamping operation, the vertical sliding stroke of the pallet 13 and the elastic deformation of the compression spring 14 work together to automatically compensate for the button tolerance within a certain thickness range. The external thread structure of the mounting ring 11 provides a standardized equipment interface. Single-handed operation is achieved through mechanical linkage. When the turntable 4 is rotated clockwise, the clamping block 3 expands outward to release the button, and when rotated counterclockwise, the clamping block 3 is driven to retract and clamp. Combined with the automatic reset function of the torsion spring 10, an anti-dropping mechanism is formed.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
