Abstract
Description
Technical Field
[0001] The utility model discloses a clamp, in particular to a movable clamp with a large range of radial adjustment. Background Art
[0002] In today's rapidly developing industrial field, efficient, flexible and reliable connection solutions are crucial for ensuring smooth production processes, improving product quality and reducing maintenance costs.
[0003] Most of the heavy-duty clamps widely used in the prior art adopt a fixed-size design, which means that for the connection technologies of equipment such as pipes, fuel tanks, pressure vessels or fuel storage tanks with different diameters, multiple specifications of clamps need to be prepared to meet the high connection requirements of the equipment. This approach not only limits its applicability in various application scenarios, but also increases the complexity of inventory management, resulting in possible delays in work progress due to the lack of a clamp with a suitable size in case of emergency. In addition, traditional clamps often require additional fastening tools during installation, and once installed, it becomes quite difficult to adjust or change the size. Summary of the Invention
[0004] The purpose of the utility model is to overcome the above deficiencies and provide a movable clamp with a large range of radial adjustment.
[0005] The object of the utility model is achieved by the following technical solutions: a movable clamp with a large range of radial adjustment, including an installation base, an upper clamp section and a lower clamp section. First through slots are provided at both ends of the upper clamp section and are curled inward to form two clamp ear rings. A lower clamp section is arranged between the two clamp ear rings. The lower clamp section is provided with a skirt. Both ends of the lower clamp section are placed on the corresponding clamp ear rings. The skirt is inserted into the arc-shaped groove on the installation base. Symmetrically arranged pairs of second through slots are provided at both ends of the installation base. A locking trunnion is arranged between each pair of second through slots. Through holes are provided in the radial direction of each locking trunnion, and threaded holes are provided on the upper and lower end faces in the axial direction. A clamp ear ring is sleeved on the circumferential surface of each of the two locking trunnions. Four socket head cap screws respectively pass through the corresponding second through slots and are threadedly connected with the threaded holes. A compression spring is arranged between the two locking trunnions. The locking bolt is inserted into one of the first through slots and the through hole of the locking trunnion at the same time, passes through the compression spring, passes through the other first through slot and the through hole of the locking trunnion, and then a nut is screwed on.
[0006] A further improvement of the utility model lies in that: neat rows of sawteeth are provided in each second through slot.
[0007] A further improvement of the utility model lies in that: a rubber soft pad is installed on the inner diameter of the upper clamp section.
[0008] The utility model has the following advantages compared with the prior art:
[0009] The biggest highlight of this utility model lies in its radial adjustment ability. In the connection application scenarios of equipment such as pipes, fuel tanks, pressure vessels or fuel storage tanks with different diameters, in the face of compensation amounts with small change amplitudes, the elastic compression amounts of the cylindrical spring and the rubber cushion can be adjusted by tightening or loosening the nut for compensation. In the face of compensation amounts with large change amplitudes, the radial distance of the lower section of the movable clamp is adjusted by turning the nut and adjusting the position of the hexagon socket head cap screw in the second through groove for compensation. The clamp can easily handle all these situations without the need to replace clamps of different specifications. This characteristic endows it with extremely high flexibility and adaptability.
[0010] In each second through groove of this utility model, there are neatly arranged sawteeth, which can prevent the clamp from falling off caused by the loosening or slipping of the nut, further improving the safety and stability of the clamp.
[0011] A rubber cushion is installed on the inner diameter of the upper section of the clamp of this utility model, which can avoid the hard contact between the clamp and the connecting component, plays a very good role in protecting the surface of the component, and can also assist in providing limited radial compensation.

Detailed Description of the Preferred Embodiment
[0017] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. The elements and features described in one embodiment of the present utility model can be combined with the elements and features shown in one or more other embodiments. It should be noted that for the sake of clarity, the representation and description of components and processes irrelevant to the present utility model and known to those of ordinary skill in the art are omitted. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.
[0018] The following further describes the present utility model with reference to the drawings: A radially adjustable large-range movable clamp includes an installation base 1, an upper clamp section 2 and a lower clamp section 3. First through slots 4 are provided at both ends of the upper clamp section 2 and are curled inward to form two clamp ear rings 5. A lower clamp section 3 is provided between the two clamp ear rings 5. The lower clamp section 3 is provided with a skirt 15. Both ends of the lower clamp section 3 are placed on the corresponding clamp ear rings 5. The skirt 15 is inserted into the arc-shaped groove on the installation base 1. The movable lower clamp section 3 can provide radial compensation for the clamp, greatly improving the usability and stability of the clamp.
[0019] Symmetric pairs of second through slots 6 are provided at both ends of the installation base 1. A locking trunnion 7 is provided between each pair of second through slots 6. Through holes are provided in the radial direction of each locking trunnion 7, and threaded holes 8 are provided on the upper and lower end faces in the axial direction. A clamp ear ring 5 is sleeved on the circumferential surface of each of the two locking trunnions 7. Four internal hexagon socket head cap screws 9 respectively pass through the corresponding second through slots 6 and are threadedly connected to the threaded holes 8. A compression spring 10 is provided between the two locking trunnions 7. The locking bolt 11 is inserted into one of the first through slots 4 and the through hole of the locking trunnion 7 at the same time, passes through the compression spring 10, and then passes through the other first through slot 4 and the through hole of the locking trunnion 7 and is screwed with a nut 12. In the connection application scenarios of equipment such as pipes, fuel tanks, pressure vessels or fuel storage tanks with different diameters, the clamp can easily handle it only by turning the nut 12 and adjusting the position of the internal hexagon socket head cap screw 9 in the second through slot 6, without the need to replace clamps of different specifications. This characteristic gives it extremely high flexibility and adaptability.
[0020] Neatly arranged sawteeth 13 are provided in each second through slot 6, which can prevent the clamp from falling off due to the loosening or slipping of the nut 12, further improving the safety and stability of the clamp.
[0021] A rubber soft pad 14 is installed on the inner diameter of the upper clamp section 2, which can avoid the hard contact between the clamp and the connecting component, plays a good role in protecting the surface of the component, and can also assist in providing limited radial compensation.
[0022] Working principle:
[0023] Put the clamp on the application position of the device object to be connected, rotate the nut 12 to radially tighten the clamp to a proper position, pass the hexagon socket head cap screw 9 through the second through slot 6 and thread it with the threaded hole 8 to complete the installation. The serrations 13 in the second through slot 6 can prevent the clamp from falling off due to the loosening or slipping of the nut 12. Since the lower section 3 of the clamp is movable, when the diameter of the component becomes smaller, tighten the nut 12, and the locking trunnion 7 drives the upper section 2 of the clamp to contract inward. The two ends of the lower section 3 of the clamp are squeezed by the clamp earring 5 to move inward. When the diameter of the component becomes larger, loosen the nut 12, and the component can press the lower section 3 of the clamp to move outward, thus completing the radial compensation.
[0024] Finally, it should be noted that although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions and transformations can be made without departing from the spirit and scope of the present invention as defined by the appended claims. Moreover, the scope of the present invention is not limited to the specific embodiments of the processes, devices, means, methods and steps described in the specification.
