Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and in particular relates to an adjustable clamp widely used in household appliances, automobiles, mechanical processing, and wire and cable industries. Background Art

[0002] A clamp is a connection device that connects grooved pipes, valves, and pipe fittings. It is used to tighten quick connectors. Generally, clamps can be divided into worm drive clamps, bolt structure clamps, etc. Worm drive clamps are widely used because of their easy installation and high fixing strength. At present, traditional bolt clamp structures such as Figure 1 As shown, a screw is screwed in and the front baffle is used to expand one end of the clamp, thereby gradually tightening the clamp. This clamp structure is suitable for pipelines with similar dimensions to the clamp. However, when tightening smaller pipelines, the screw force is applied at the ends of the clamp, causing the ends of the clamp to move toward each other, achieving continuous tightening of the clamp. However, the position of the screw is fixed and cannot be adjusted. As a result, the clamp's clamping force is mainly concentrated on the two sides of the pipeline when tightening, which can easily cause pipeline deformation or limited sealing effect. Utility Model Content

[0003] In view of the above problems, the utility model discloses an adjustable clamp structure, which can adjust the angle of the screw, thereby making the clamp size adaptable to a wider range.

[0010] Furthermore, a movable gap is left between the notch and the rotating shaft.

[0011] The beneficial effects of the present invention are as follows:

[0012] When the clamp of the utility model is used to clamp a pipeline of slightly smaller size, the angle of the screw can be adjusted by adjusting the position of the movable screw sleeve upwards, thereby changing the direction of the force of the positioning pin and avoiding the problem that the clamp ring is severely deformed and the clamping effect is affected.

[0021] like Figure 2-5 As shown, this embodiment provides an adjustable clamp structure, including a hoop body 1, a movable threaded seat 2, a limit seat 3, a screw 4 and a positioning pin 5. The ends of the hoop body 1 are staggered with each other, and the ends of the hoop body 1 are respectively fixed with a movable threaded seat 2 and a limit seat 3. The movable threaded seat 2 includes a fixed plate 21 and a movable screw sleeve 22. The fixed plate 21 is longitudinally arranged and fixedly connected to one end of the hoop body 1. The fixed plate 21 is curved in an arc shape. A movable opening 211 is longitudinally opened on the fixed plate 21, and a movable screw sleeve 22 is movably arranged in the movable opening 211. The movable screw sleeve 22 is transversely threadedly connected to the screw 4. The front end of the screw 4 is rotatably connected to a rotating shaft 41. The rotating shaft 41 is arranged along the length direction of the screw 4. A screw hole 42 is horizontally penetrated on the rotating shaft 41, and the screw hole 42 is threadedly connected to the positioning pin 5. The length of the positioning pin 5 at both ends of the rotating shaft 41 is equal. The limit seat 3 is longitudinally arranged on the other end of the hoop body 1, and a recess 31 is provided in the center of the limit seat 3 for the front end of the rotating shaft 41 to pass through. A movable gap is left between the recess 31 and the rotating shaft 41 to ensure that the screw 4 can move in the recess 31. Positioning plates 32 are symmetrically provided on both sides of the limit seat 3. Both positioning plates 32 are provided with grooves 321 for accommodating the two ends of the positioning pin 5. The grooves 321 are arranged in an arc-shaped structure and are adapted to the diameter of the positioning pin 5, so that during the rotation and translation process of the screw 4, the positioning pin 5 is used as the center and the movable screw sleeve 22 is moved up and down in the movable opening 211 to realize the adjustment of the angle of the screw 4.

[0022] In this embodiment, the hoop body 1 is integrally formed and has a double-layer structure. One end of the hoop body 1 is bent upward and has an inverted U-shaped structure, and the other end of the hoop body 1 is bent upward and has a hook-shaped structure. The other end of the hoop body 1 passes through both sides of the fixing plate 21 for fixation. The limit seat 3 has an inverted U-shaped structure and is adapted to the size and shape of the end of the hoop body 1.

[0023] In this embodiment, the movable screw sleeve 22 includes a screw sleeve portion 221 and a slide portion 222 arranged on the outside of the screw sleeve portion 221. The slide portion 222 is curved in an arc shape and adapted to the bending angle of the fixed plate 21. Slide grooves 223 are symmetrically provided on both sides of the slide portion 222. The two slide grooves 223 are respectively embedded in the two sides of the movable opening 211 to realize the sliding connection between the movable screw sleeve 22 and the fixed plate 21.

[0024] When the clamp of this embodiment is used, the front end of the screw rod 4 is first screwed into the movable screw sleeve 22, and the positioning pin 5 is then screwed horizontally into the screw hole 42 of the rotating shaft 41. During the screw rod 4 being screwed in, the two ends of the positioning pin 5 are respectively embedded in the grooves 321 on both sides of the limit seat 3 for positioning. As the screw rod 4 continues to move and is pushed by the positioning pin 5 and the action of the thread, the clamp body 1 is continuously tightened. When the clamp body 1 undergoes elliptical deformation due to the applied force, the position of the movable screw sleeve 22 can be adjusted upwards, and the angle of the screw rod 4 can be adjusted to change the applied force direction of the positioning pin 5, so as to avoid the continued deformation of the clamp body 1 and ensure the clamping effect of the clamp, thereby making it suitable for pipelines with slightly smaller diameters.

[0025] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
