[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] For reference Figure 1-4 The utility model is described as follows:
[0022] Embodiment 1: An adjustable clamp includes a first snap ring 1 and a second snap ring 2, one end of the first snap ring 1 and one end of the second snap ring 2 are hinged, a first bite tooth 3 is provided on the outer side wall of the other end of the first snap ring 1, a plurality of first bite teeth 3 are provided, and the plurality of first bite teeth 3 are arranged in sequence in the length direction of the first snap ring 1, and a second bite tooth 4 is provided on the inner side wall of the other end of the second snap ring 2, a plurality of second bite teeth 4 are provided, and the plurality of second bite teeth 4 are arranged in sequence in the length direction of the second snap ring 2. When the other end of the first snap ring 1 and the other end of the second snap ring 2 are close to each other and buckled, the first bite tooth 3 and the second bite tooth 4 can bite each other to limit the other end of the first snap ring 1 and the other end of the second snap ring 2 from separating.
[0023] The design of the adjustable clamp of the present application has some unique features and advantages. First, by setting the first engaging teeth 3 and the second engaging teeth 4 that engage with each other to achieve snap-on and limit separation, compared with the traditional bolt fastening method, it reduces the reliance on additional parts such as bolts and simplifies the structure. The design of multiple engaging teeth arranged in sequence allows the clamp to have more choices and a finer adjustment range when adjusting the tightness. According to actual needs, engaging teeth in different positions can be selected for engagement, thereby achieving different degrees of tightening. In practical applications, this design can provide a more stable and reliable tightening effect. Due to the interaction of the engaging teeth, the clamp is not prone to loosening when subjected to external force or vibration.
[0024] When the other ends of the first snap ring 1 and the second snap ring 2 are close to each other and snapped together, the first bite teeth 3 and the second bite teeth 4 can bite each other. A plurality of first bite teeth 3 and second bite teeth 4 arranged in sequence increase the contact area and stability of the bite. Since the first bite teeth 3 are arranged on the outer wall of the first snap ring 1 and the second bite teeth 4 are arranged on the inner wall of the second snap ring 2, such a design enables the first bite teeth 3 and the second bite teeth 4 to effectively block each other in the snapped state, limiting the separation of the other end of the first snap ring 1 and the other end of the second snap ring 2, thereby achieving the tightening effect on the object. By selecting the first bite teeth 3 and the second bite teeth 4 at different positions to bite each other, the tightening degree of the clamp can be adjusted within a certain range to adapt to objects of different sizes or requiring different tightening forces.
[0025] The other end of the second snap ring 2 is provided with a locking ring 5, and the second engaging teeth 4 are arranged on the locking ring 5. The first snap ring 1 and the second snap ring 2 can form a circular ring structure, and the inner diameter of the locking ring 5 is larger than the outer diameter of the first snap ring 1 and the second snap ring 2. This arrangement facilitates the other end of the first snap ring 1 to enter the inner side of the locking ring 5 when the first snap ring 1 and the second snap ring 2 are close to each other and buckled, so that the jamming or difficulty in buckling caused by size limitation can be avoided, making the operation more convenient, and also providing a certain guiding and positioning effect for the first snap ring 1 to enter the locking ring 5, so that the mutual engagement of the engaging teeth is more accurate and stable.
[0026] The first clasp 1 is composed of two sections, the two sections of the first clasp 1 are respectively the first clasp 11 and the second clasp 12, one end of the first clasp 11 is hinged to the second clasp 2, the other end of the first clasp 11 is hinged to the second clasp 12, and the first bite tooth 3 is arranged on the second clasp 12. With this technical solution, when the first bite tooth 3 and the second bite tooth 4 need to be disengaged, pressure is applied to the second clasp 12 to move it inward. Since the first clasp 11 is hinged to the second clasp 2 and the second clasp 12, respectively, the movement of the second clasp 12 will drive the first bite tooth 3 to move, so that the bite of the first bite tooth 3 and the second bite tooth 4 is separated, so that the clasp can be opened. The advantage of this design is that the opening operation of the clasp is relatively simple, and no complicated steps or specific tools are required. At the same time, through the hinged structure, the moving direction and distance of the first bite tooth 3 can be better controlled to ensure the accuracy and stability of the bite separation.
[0027] The inner side walls of the second retaining ring 2 and the first section retaining ring 11 are provided with protruding anti-rotation protrusions 6. First, the anti-rotation protrusions 6 can increase the friction between the retaining ring and the fastened object, thereby effectively preventing the fastened object from rotating inside the retaining ring. Secondly, the anti-rotation protrusions 6 can improve the fastening stability of the retaining ring. When the retaining ring fastens the object, the raised portion can be embedded in the tiny grooves or unevenness on the surface of the object, further enhancing the retaining ring's grip on the object and reducing loosening caused by vibration or external force. In addition, the anti-rotation protrusions 6 can also disperse the pressure on the retaining ring to a certain extent, avoiding deformation or damage of the retaining ring caused by excessive local pressure, thereby extending the service life of the retaining ring.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
