Description

Technical Field

[0001] The present application belongs to the technical field of fasteners, and in particular relates to a portable clamp. Background Art

[0002] Clamps are typically made of metal and are used to secure pipes and fittings together, ensuring the safety and stability of piping systems during transportation and operation. Shaped like a ring, they wrap tightly around the outside of the pipe, securely connecting the pipe and fittings together and preventing them from loosening or separating. Clamps are widely used in industries such as aviation, automotive, construction, chemical and food processing, pharmaceuticals, and semiconductor cleanroom piping, as well as in everyday life, often used to secure and support pipes and equipment. Using clamps can improve the stability and safety of equipment.

[0003] In existing practices, even with parameters and training, the construction process still relies on operators strictly following the standards. In practice, without a rigorous review process, verifying this condition is difficult. In this situation, the simplest solution to temporarily prevent leakage is to tighten the bolts until they can no longer be tightened.

[0004] However, tightening a bolt to its limit can lead to the following direct consequences: breaking the bolt or stripping. Bolt strength is fixed, and exceeding this limit can cause the bolt to break or strip. Alternatively, the bolt may not break during installation, but changes in fluid pressure or temperature may cause the bolt tension to exceed a critical value, leading to breakage or stripping. A broken bolt could cause the chuck to break, releasing pressure in the pipeline and injuring nearby personnel, or leaking fluid from the pipeline, causing contamination. A new technology has been proposed to address this issue. Utility Model Content

[0029] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0030] This embodiment provides a portable clamp, comprising an upper locking member 1 and a lower locking member 2, both of which have sealing grooves on their opposite inner sides. The upper locking member 1 and the lower locking member 2 are adapted to the shape of the pipe fitting and are both arc-shaped. The upper locking member 1 and the lower locking member 2 are connected on one side by a rotating structure and on the other side by a movable structure 3. The movable structure 3 includes a buckle seat 5, a connecting seat 6, and a connecting body 7. The buckle seat 5 is located at the end face of the lower locking member 2, and the connecting seat 6 is located at the end face of the upper locking member 1. One end of the connecting body 7 is hinged to the connecting seat 6, and the other end is buckled to the buckle seat 5. The buckle seat 5 is provided with a buckle groove 9 for matching buckle connection.

[0031] The connecting body 7 includes a first end 8, a second end 15, a movable pin 16 located between the first end 8 and the second end 15, and a limiting sleeve 18 sleeved on the second end 15. The first end 8 is hinged on the connecting seat 6, the limiting sleeve 18 is sleeved on the movable pin 16 and partially sleeved on the outside of the second end 15, and the outside of the second end 15 is provided with a plurality of positioning grooves 19 of different depths. The limiting sleeve 18 is provided with a plurality of claws 20 that match and buckle with the positioning grooves 19. The limiting sleeve 18 is buckled in the buckle groove 9. The limiting sleeve 18 is rotated to change the claw to enter the positioning grooves 19 of different depths, thereby adjusting the position of the limiting sleeve 18 on the movable pin 16 and adjusting the gap between the upper locking member 1 and the lower locking member 2.

[0032] In order to tighten the upper locking member 1 and the lower locking member 2 again, an outer hoop structure 4 is provided at one end of the upper locking member 1 close to the movable structure 4 to offset the movable gap of the movable structure so that the upper locking member 1 and the lower locking member 2 are tightly embraced, thereby achieving complete locking;

[0033] Specifically, the outer hoop structure 4 includes a card 10 that matches the shape of the locking piece 1 and a connecting component 11. The central angles of the card 10 and the locking piece 1 are equal, and the lengths of the card 10 and the locking piece 1 are close. The structure is stable when buckled, and the card 10 is not easy to detach from the locking piece 1. One end of the card 10 is pivotally connected to one end of the locking piece 1 close to the movable structure, and the other end is attached to the outer surface of the locking piece 1 and can be movably connected to the locking piece 1 through the connecting component 11. The connecting component 11 can release the card 10 or fix the card 10 on the locking piece 1.

[0034] In order to facilitate the opening and positioning of the card 10, the connecting component 11 includes a limiting hole 12 provided at the free end of the card, a limiting seat 24 protruding outward on the locking member 1, and the limiting seat 24 is provided with a positioning pin 14 that can be inserted into the limiting hole 12. The positioning pin 14 is a spring pin with a spring, and the spring part is located in the limiting seat 24. The pin head of the positioning pin 14 can be compressed into the limiting seat 24 by external force and popped out of the limiting seat 24 by the spring force. The free end of the card 10 has a protruding block protruding from one side of the limiting seat 24, and the positioning pin 14 is arranged there so that the card 10 and the limiting seat 24 match and fit together.

[0035] In order to hide the card 10 and prevent it from being exposed to the outside, which may cause it to be displaced, knocked open, and detached from the locking member 1 under the action of external force, a groove 21 is provided on the circumferential outer surface of the locking member 1 to accommodate the card 10, which can hide the locking member 1. In order to hide the card 10 while facilitating the opening of the card 10, side grooves 13 that are easy to grasp and separate the card 10 from the locking member 1 are provided on the front and rear sides of the locking member 1 and opposite to the groove 21. The hands are located on both sides of the side grooves 13, slide outward to grasp the card 10, and separate the card 10 from the locking member 1.

[0036] A limit assembly for limiting the movement of the locking member 10 is provided at the corresponding position of the locking member 1 and the card member 10; the limit assembly includes a socket 22 provided on the card member 10 and a positioning block 23 protruding outward provided on the locking member 1, and the positioning block 23 is inserted into the socket 22 to firmly stabilize the card member 10.

[0037] In order to make it easier for the claw 20 of the limiting sleeve 18 to engage with the positioning groove 19 , a sliding circuit 25 is provided at one end of the movable pin 16 close to the second end 15 , and the inner ring shape of the limiting sleeve 18 matches the sliding circuit 25 .

[0038] In order to reduce weight without affecting structural stability, weight-reducing grooves 17 are provided on the outer surfaces of the upper locking member 1 and the lower locking member 2. The weight-reducing grooves 17 can be V-shaped grooves, U-shaped grooves or other special-shaped grooves. U-shaped grooves are preferred here, and one or more can be provided on an outer side surface.

[0039] When the utility model is implemented:

[0040] Align the flange end faces of the two pipe fittings, place a sealing ring in the middle, then open the upper locking piece and the lower locking piece, and buckle them at the aligned position of the two pipe fittings, with the sealing ring and the flange end face of the pipe fitting in the sealing groove. Then hold the connector so that the limiting sleeve of the connector is partially buckled in the buckle groove, and then pull the clamp in the direction away from the connector and rotate the clamp into the groove. Then, because the clamp squeezes the locating pin, the locating pin is hidden in the fixing seat. When the locating pin corresponds to the position of the locating hole, it pops out to the locating hole due to the force of the spring, fixes the clamp, and completes the fastening installation of the pipe fitting. Moreover, such a structural design will not squeeze the sealing ring, causing the sealing ring to expand into the pipe, affecting the flow of liquid in the pipe and causing scaling problems.

[0041] Based on the above-mentioned ideal embodiments of this application, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
