Description

Technical Field

[0001] This utility model relates to the field of clamp assembly technology, and in particular to a high-sealing clamp assembly. Background Technology

[0002] A clamp is a connecting device for connecting grooved pipe fittings, valves, and pipeline accessories. The most common clamps on the market are mostly double-bolt locking structures. The clamp is tightened by tightening the bolts on both sides of the lug, thereby holding the internal hose or pipe fitting tightly to achieve a seal.

[0003] However, in existing equipment, operators can hardly tighten two bolts completely and synchronously. One bolt is always partially or fully tightened first, and then the other is tightened. This causes the clamp to be stressed first on the side that is locked first, causing the clamp to twist and deform during the tightening process, affecting the sealing performance. Therefore, a high-sealing clamp component is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-sealing clamp assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-sealing clamp assembly, comprising a first clamp and a second clamp, wherein a first ear seat is fixedly connected to the side of the second clamp that is away from each other, a sliding post is fixedly connected to one side of each first ear seat, and a locking hole is provided on one side of each sliding post; a second ear seat is fixedly connected to the side of the first clamp that is away from each other, and a sliding hole is provided on one side of each second ear seat, and each sliding hole is adapted to the corresponding sliding post; a rotating seat is fixedly connected to one side of the first clamp, and a tightening structure is provided on the rotating seat;

[0006] The tightening structure includes a threaded rod rotatably connected to one end of the rotating seat. A pull plate is threadedly connected to the threaded rod, and a locking ring is fixedly connected to one side of the pull plate. A locking nut is threadedly connected to the threaded rod. Tightening the locking nut makes its end face fit tightly against the locking ring, thereby locking the threaded rod and improving the stability of the entire tightening structure.

[0007] As a further description of the above technical solution:

[0008] Two limiting rods are slidably connected through one side of the pull plate. One end of each limiting rod is fixedly connected to one side of the first clamp. Rotating the threaded rod causes the pull plate to slide on the two limiting rods.

[0009] As a further description of the above technical solution:

[0010] Two connecting blocks are fixedly connected to one side of the pull plate. Each connecting block has a snap-fit ​​groove on one side. Each snap-fit ​​groove is adapted to a corresponding sliding post. The two sliding posts on the second clamp pass through the corresponding sliding holes and slide into the corresponding snap-fit ​​grooves.

[0011] As a further description of the above technical solution:

[0012] Each of the connecting blocks is fixedly connected to a fixed frame on one side, and a sliding rod is slidably connected to one side of each fixed frame. A handle fork is rotatably connected to one end of each sliding rod. One side of each handle fork is in contact with the outer side of the corresponding fixed frame. Moving the handle fork causes the sliding rod to move.

[0013] As a further description of the above technical solution:

[0014] The other end of each sliding rod is fixedly connected to a locking post. Each locking post is slidably connected through to one side of the corresponding connecting block and is adapted to the corresponding locking hole. The sliding rod drives the locking post to retract and compress the reset spring.

[0015] As a further description of the above technical solution:

[0016] Each sliding rod is fitted with a return spring. One end of each return spring is fixedly connected to the inside side of the corresponding fixed frame, and the other end is fixedly connected to one side of the locking post. Under the elasticity of the return spring, the locking post is pushed to move, so that the locking post is engaged in the corresponding locking hole.

[0017] As a further description of the above technical solution:

[0018] The first clamp and the second clamp each have a sealing groove on their opposite sides. An elastic sealing ring is engaged inside both sealing grooves. The elastic sealing ring is put into place, and then the first clamp and the second clamp are aligned so that the elastic sealing ring is embedded in the two sealing grooves.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this high-sealing clamp assembly, through the setting of threaded rods, pull plates, limit rods, connecting blocks, fixing frames, sliding rods, locking pins, handle forks, and return springs, allows the first clamp and the second clamp to mate, so that the elastic sealing ring is embedded in two sealing grooves. The two sliding pins on the second clamp pass through the corresponding sliding holes and slide into the corresponding locking grooves. Then, by moving the handle fork again, under the elasticity of the return spring, the locking pin is pushed to move, so that the locking pin is locked into the corresponding locking hole, thus locking and fixing the sliding pin. Then, by rotating the threaded rod, the threaded rod drives the pull plate to slide on the two limit rods. The pull plate drives the two locked sliding pins to move through the connecting block. The two sliding pins drive the second clamp to move, so that the second clamp is close to the first clamp and squeezes the elastic sealing ring to form a seal. This avoids the twisting and deformation of the first and second clamps due to the force on one side first, thus improving the reliability of the seal.

[0021] 2. Compared with the existing technology, this high-sealing clamp assembly, by setting a locking ring and a locking nut, tightens the locking nut so that its end face fits tightly with the locking ring, thereby locking the threaded rod and improving the stability of the entire tightening structure.

[0029] 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.

[0030] Reference Figures 1 to 5 This utility model provides a high-sealing clamp assembly, comprising a first clamp 1 and a second clamp 2. Each of the first clamp 1 and the second clamp 2 has a sealing groove 3 on its opposite side. An elastic sealing ring 4 is engaged within both sealing grooves 3. The elastic sealing ring 4 is fitted into place, and then the first clamp 1 and the second clamp 2 are aligned so that the elastic sealing ring 4 is embedded in the two sealing grooves 3. Each of the second clamp 2 has a first ear seat 5 fixedly connected to its opposite side. Each first ear seat 5 has a sliding post 6 fixedly connected to one side, and each sliding post 6 has a locking hole on one side. Each of the first clamp 1 has a second ear seat 7 fixedly connected to its opposite side, and each second ear seat 7 has a sliding hole on one side, each sliding hole being adapted to the corresponding sliding post 6. A rotating seat 8 is fixedly connected to one side of the first clamp 1, and the rotating seat 8 has a tightening structure 9.

[0031] To achieve the tightening purpose, the tightening structure 9 includes a threaded rod 901 rotatably connected to one end of the rotating seat 8. A pull plate 902 is threadedly connected to the threaded rod 901. Two limiting rods 904 are slidably connected through one side of the pull plate 902. One end of each limiting rod 904 is fixedly connected to one side of the first clamp 1. Two connecting blocks 905 are fixedly connected to one side of the pull plate 902. Each connecting block 905 has a snap-fit ​​groove on one side, and each snap-fit ​​groove is adapted to the corresponding sliding post 6. A fixing frame 906 is fixedly connected to one side of each connecting block 905. A sliding rod 907 is slidably connected through one side of each fixing frame 906. A handle fork 909 is rotatably connected to one end of each sliding rod 907. One side of each handle fork 909 is in contact with the outer side of the corresponding fixing frame 906. A locking post 908 is fixedly connected to the other end of each sliding rod 907. A return spring 910 is sleeved on each sliding rod 907. Each end is fixedly connected to one side of the corresponding fixed frame 906, and the other end is fixedly connected to one side of the locking post 908. Each locking post 908 is slidably connected to one side of the corresponding connecting block 905 and is adapted to the corresponding locking hole. The two sliding posts 6 on the second clamp 2 pass through the corresponding sliding hole and slide into the corresponding snap-fit ​​groove. Then, the handle fork 909 is turned again. Under the elasticity of the return spring 910, the locking post 908 is pushed to move, so that the locking post 908 is snapped into the corresponding locking hole to snap and fix the sliding post 6. Then, the threaded rod 901 is rotated. The threaded rod 901 drives the pull plate 902 to slide on the two limit rods 904. The pull plate 902 drives the two locked sliding posts 6 to move through the connecting block 905. The two sliding posts 6 drive the second clamp 2 to move, so that the second clamp 2 is close to the first clamp 1 and squeezes the elastic sealing ring 4 to form a seal. This avoids the first clamp 1 and the second clamp 2 from being twisted and deformed due to the force on one side first, and improves the reliability of the seal.

[0032] To achieve the locking purpose, a locking ring 903 is fixedly connected to one side of the pull plate 902, and a locking nut 911 is threadedly connected to the threaded rod 901. Tightening the locking nut 911 makes its end face fit tightly against the locking ring 903, thereby locking the threaded rod 901 and improving the stability of the entire tightening structure 9.

[0033] Working principle: After the elastic sealing ring 4 is properly fitted, the handle fork 909 is turned. The handle fork 909 moves the sliding rod 907, which in turn moves the locking pin 908 back and compresses the return spring 910. Then, the first clamp 1 and the second clamp 2 are aligned, allowing the elastic sealing ring 4 to be embedded in the two sealing grooves 3. The two sliding pins 6 on the second clamp 2 pass through the corresponding sliding holes and slide into the corresponding locking grooves. Then, the handle fork 909 is turned again. Under the elasticity of the return spring 910, the locking pin 908 is pushed to move, causing the locking pin 908 to engage in the corresponding locking hole, thus locking the sliding pin. 6. Secure the connection by clamping, then rotate the threaded rod 901. The threaded rod 901 drives the pull plate 902 to slide on the two limit rods 904. The pull plate 902 drives the two locked sliding pins 6 to move through the connecting block 905. The two sliding pins 6 drive the second clamp 2 to move, so that the second clamp 2 is close to the first clamp 1 and squeezes the elastic sealing ring 4 to form a seal. This avoids the first clamp 1 and the second clamp 2 from twisting and deforming due to the force on one side first, and improves the reliability of the seal. Then tighten the locking nut 911 so that its end face is tightly fitted with the locking ring 903, thereby locking the threaded rod 901 and improving the stability of the entire tightening structure 9.
