Description

Technical Field

[0001] This utility model relates to the field of pipe fastener technology, and in particular to an anti-deformation clamp. Background Technology

[0002] Pipeline connection is a fundamental link in industrial production and civil facilities. Its sealing performance and reliability directly affect the safety of system operation. Currently, the mainstream pipeline connection methods on the market include flange connection, threaded connection and clamp connection. Among them, clamp connection occupies an important position in the connection of small and medium diameter pipelines due to its convenient installation and strong adaptability. In recent years, with the development of materials science, new materials such as stainless steel and high-strength alloy clamps have emerged continuously.

[0003] A search revealed Chinese publication number CN104662352B, which discloses a combination of a pipe and an ear clip for sealing the pipe onto an object inserted into the pipe, as well as a method for sealing the pipe onto the object to be inserted into the pipe by means of the ear clip. In the combination of the pipe and the ear clip for sealing the pipe onto the object inserted into the pipe of the present invention, the ear clip has a clamping band, an ear-shaped fastening device formed in the clamping band, and two outwardly extending legs connected to each other by ribs.

[0004] The aforementioned patent states in its specification that "before placing the ear clip on the pipe 10, the ear 12 is pre-deformed to a certain extent so that the clip surrounds the pipe without any play. Preferably, the pre-deformation is completed during the manufacturing process of the clip and can be easily performed so that the elasticity of the pre-deformed ear allows the clip to be placed on the pipe and moved to the installation position effortlessly, while still keeping the clip in that position and maintaining the orientation suitable for fastening the ear 12." Although this patent ensures the stability of the position relative to the pipe body during installation, the clamp at the clamp ear will deform and bulge upwards under stress, resulting in a gap between the clamp and the surface of the pipe fitting, affecting the sealing effect. Therefore, an anti-deformation clamp is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an anti-deformation clamp, which aims to improve the problem in the prior art where the clamp at the clamp lug deforms and bulges upward under stress, resulting in gaps between the clamp and the pipe surface, thus affecting the sealing effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-deformation clamp includes two clamp bodies. A tube body is slidably connected inside the clamp body. An installation mechanism and a limiting mechanism are provided outside the clamp body. The installation mechanism includes a sliding band, which is slidably connected to the outside of the clamp body. Two clamping bands are fixedly connected to the outside of the sliding band. A guide block is fixedly connected inside the clamp body. A clamping post is fixedly connected to the outside of the sliding band. A fixing box is fixedly connected to the outside of the clamp body. A protective component is provided outside the clamp body.

[0008] Through the above technical solution, the sliding belt, clamp, guide block, clamp post, fixing box and protective components in the installation mechanism work together to realize the convenient installation and fastening of the clamp to the pipe body. At the same time, the protective components can prevent the clamp from deforming to a certain extent, ensuring the stability and sealing of the connection between the clamp and the pipe body.

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

[0010] The sliding strip has a sliding groove on its outside, and the guide block is slidably connected to the inside of the sliding groove.

[0011] Through the above technical solution, the guide block slides in the sliding groove, providing precise guidance for the sliding of the sliding band, ensuring that the sliding band moves stably and accurately in the clamp body, avoiding deviation, improving the installation accuracy, and thus ensuring that the clamp can evenly grip the pipe body.

[0012] As a further description of the above technical solution:

[0013] The outer side of the locking post is slidably connected to the inside of the hoop, and the outer side of the locking post is slidably connected to the inside of the fixing box;

[0014] The above technical solution, which uses a sliding connection between the clamping post, the hoop, and the fixing box, allows the clamping post to move smoothly during installation. When the sliding band and the clamping band slide to the appropriate position, the clamping post can be engaged in the fixing box to effectively secure the pipe body, prevent the hoop and the sliding band from loosening, and enhance the reliability of the clamp connection.

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

[0016] The hoop body has a sliding groove inside, and the outer part of the card is slidably connected to the inside of the sliding groove;

[0017] Through the above technical solution: the sliding groove provides a track for the sliding of the cassette, making the cassette more stable when sliding, ensuring that the two sets of cassettes can slide synchronously when the sliding belt is pulled, so that the clamp is subjected to more even force during installation, effectively avoiding the overall deformation of the clamp due to excessive tension on one side, and improving the stability of the clamp.

[0018] As a further description of the above technical solution:

[0019] The protective component includes a hoop lug, the outside of which is fixedly connected to one side of the two hoop bodies, and the inside of which is fixedly connected to a pressing member;

[0020] The above technical solution connects two clamps, and the elasticity of the extrusion component plays a role when the clamp is pulled, which can effectively prevent the sliding band from deforming and bulging upward under force, ensuring that the clamp is tightly fitted to the pipe surface. Especially in pipeline connections with high pressure or highly corrosive media, it greatly improves the sealing effect and avoids the risk of leakage.

[0021] As a further description of the above technical solution:

[0022] The limiting mechanism includes two rotating rods, the rear ends of which are rotatably connected to the front end of the hoop. The rotating rods are internally threaded with threaded posts, and the sliding band is externally fixedly connected with a limiting box.

[0023] Through the above technical solution: the rotating rod, the threaded column, and the limiting box cooperate with each other. The rotating rod can rotate flexibly at the front end of the clamp, which facilitates the subsequent fixing operation. The threaded connection between the threaded column and the rotating rod facilitates precise adjustment. The limiting box provides the point of action for the fixing operation. The three work together to lay the foundation for preventing the clamp from loosening.

[0024] As a further description of the above technical solution:

[0025] The rotating rod is in contact with the outside of the limiting box, and the outside of the threaded column is slidably connected to the inside of the limiting box;

[0026] Through the above technical solution: the rotating rod contacts the limiting box, the threaded column slides inside the limiting box, and after the clamp is installed, the rotating rod is rotated to make it fit with the limiting box for initial positioning. Then the threaded column is rotated to engage with the limiting box, thereby fixing the clamped column and the fixed box in a locked state, effectively preventing the clamp from loosening due to vibration and shaking during use.

[0027] As a further description of the above technical solution:

[0028] The rear ends of the two rotating rods are symmetrically distributed at the front end of the hoop, and the extrusion member is elastic and plays a role in preventing deformation;

[0029] The above technical solution involves two symmetrically distributed rotating rods, which makes the fixing of the clamp by the limiting mechanism more stable and reliable. The elasticity of the extrusion component continues to prevent the clamp from deforming, ensuring that the clamp can stably tighten the pipe body under various working conditions, extending the service life of the clamp, and ensuring the safe operation of pipeline components.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, when installing the clamp, first put the clamp and sliding band on the pipe body, use pliers to clamp the fixing box and the limiting box and pull the sliding band and clamp, so that the sliding band and clamp slide in the clamp body and fit tightly against the pipe body until the clamp is inserted into the fixing box to complete the fastening. During this process, the extrusion part generates elasticity to prevent the sliding band from deforming and bulging, affecting the seal. The synergistic effect of the two sets of clamps and clamps avoids the clamp from being deformed on one side, ensuring stable and reliable installation and improving the sealing performance.

[0032] 2. In this utility model, after the clamp is installed, the rotating rod is rotated to make it fit against the limiting box, and then the threaded column is rotated to make it snap into the limiting box, thereby fixing the snapping state between the clamp and the fixing box. This operation can effectively prevent the clamp from loosening due to vibration and shaking during normal use, ensuring the clamp's continuous tightness to the pipe body, ensuring stable pipe connection, avoiding safety hazards caused by loosening, and extending the service life of the clamp and pipe components.

[0039] 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.

[0040] Reference Figures 1 to 3 This utility model provides an embodiment of an anti-deformation clamp, comprising two clamp bodies 1, with a pipe body 2 slidably connected inside the clamp body 1. An installation mechanism 3 is provided on the outside of the clamp body 1, enabling convenient installation and fastening of the clamp. A limiting mechanism 4 is also provided on the outside of the clamp body 1, effectively preventing loosening during use and ensuring connection stability. The installation mechanism 3 includes a sliding band 31, which is slidably connected to the inside of the clamp body 1. This sliding connection allows the sliding band 31 to move smoothly within the clamp body 1, facilitating subsequent fastening operations. During installation, the sliding of the sliding band 31 drives the clamping tape 32 to move together, thereby achieving tight fixation of the pipe body 2. Two clamping tapes 32 are fixedly connected to the outside of the sliding band 31. The design of two sets of clamping tapes 32 enables the clamp to... The clamp is more evenly stressed during installation. When the sliding band 31 is pulled, the clamp 32 slides synchronously, which avoids the situation where excessive tension on one side during installation causes the clamp to deform as a whole, greatly improving the stability and reliability of the clamp. The clamp body 1 is internally fixedly connected with a guide block 33. The function of the guide block 33 is to provide precise guidance for the sliding of the sliding band 31. During the movement of the sliding band 31, the guide block 33 always slides in the sliding groove 34 to ensure that the sliding band 31 moves in the correct direction and prevents deviation, thus ensuring the accuracy of installation. The sliding band 31 is externally fixedly connected with a locking post 35. The locking post 35 plays a key positioning and locking role in the entire installation process. When the sliding band 31 and the clamp 32 slide to the appropriate position, the locking post 35 will lock into the fixed box 36 to achieve the fastening of the pipe body 2 and prevent the clamp body 1 and the sliding band 31 from loosening.

[0041] Specifically, during installation, first, put the hoop 1 and the sliding band 31 on the outside of the pipe body 2. Then, use calipers to clamp the fixing box 36 and the limiting box 43, and pull the sliding band 31. The sliding band 31 slides inside the hoop 1, driving the clamping band 32 to slide synchronously along the sliding groove inside the hoop 1, evenly tightening the pipe body 2. During the sliding process, the guide block 33 slides in the sliding groove 34 of the sliding band 31 to ensure that the sliding band 31 moves in the correct direction. When it slides to the appropriate position, the clamping post 35 is inserted into the fixing box 36, completing the initial tightening of the pipe body 2.

[0042] The clamp 1 is externally fixedly connected to a fixing box 36. The fixing box 36 and the clamping post 35 cooperate to complete the fastening operation of the pipe body 2. When the clamping post 35 is inserted into the fixing box 36, the two are tightly fitted, fixing the position of the sliding band 31 and the clamp 1, ensuring that the clamp tightly holds the pipe body 2 and guaranteeing the connection's firmness. The clamp 1 is externally provided with a protective component 37, which protects the clamp and enhances its anti-deformation ability. The sliding band 31 has a sliding groove 34 on its outside, and the guide block 33 is externally slidably connected to the inside of the sliding groove 34. This groove and block cooperation method further improves the stability and accuracy of the sliding band 31's sliding, making the clamp installation operation smoother. The clamping post 35 is externally slidably connected to the inside of the clamp 1 and the fixing box 36. This connection method allows the clamping post 35 to move flexibly between the clamp 1 and the fixing box 36, realizing the clamp's installation. The clamp 1 has a sliding groove inside, and the external part of the clamp 32 is slidably connected to the inside of the sliding groove. The sliding groove provides a track for the sliding of the clamp 32, ensuring that the clamp 32 can slide stably, thereby achieving uniform clamping of the pipe body 2. The protective component 37 includes a clamp lug 371, which is externally fixedly connected to the adjacent side of the two clamps 1. The clamp lug 371 not only connects the two clamps 1, but also provides an installation position for the extrusion component 372. The extrusion component 372 is fixedly connected inside the clamp lug 371. The extrusion component 372 is elastic and plays a role in preventing deformation. When the clamp 1 is pulled, the extrusion component 372 will generate elasticity, thereby preventing the sliding band 31 from deforming and bulging upward under force, which would cause gaps between the clamp and the surface of the pipe body 2 and affect the sealing effect. In pipeline connections with high pressure or highly corrosive media, this anti-deformation design is particularly important, which can effectively avoid leakage risks and ensure the safe operation of pipeline components.

[0043] Specifically, the lug 371 of the protective component 37 connects two clamps 1. The extrusion member 372 inside the lug 371 generates elasticity when the clamp 1 is pulled. This elasticity can prevent the sliding band 31 from deforming and bulging upward under force, ensuring that the clamp is tightly fitted to the pipe body 2 and maintaining a good sealing effect, effectively preventing leakage in high pressure or highly corrosive media pipeline connections.

[0044] Reference Figure 1 , Figure 3 and Figure 4The limiting mechanism 4 includes two rotating rods 41, the rear ends of which are rotatably connected to the front end of the clamp 1. The design of the rotating rods 41 allows them to rotate flexibly at the front end of the clamp 1, facilitating subsequent fixing operations. The rear ends of the two rotating rods 41 are symmetrically distributed at the front end of the clamp 1. This symmetrical distribution makes the fixing of the clamp by the limiting mechanism 4 more stable and reliable. The internal threads of the rotating rods 41 are connected to threaded posts 42. The threaded connection between the threaded posts 42 and the rotating rods 41 enables precise adjustment. By rotating the threaded posts 42, they can be accurately engaged inside the limiting box 43, firmly fixing the engagement state of the posts 35 and the fixing box 36. The external fixed connection of the sliding belt 31 to the limiting box 43 allows for rotation... The rod 41 contacts the outside of the limiting box 43, and the threaded column 42 is slidably connected to the inside of the limiting box 43. After the clamp is installed, the rotating rod 41 is rotated to make the rotating rod 41 fit against the outside of the limiting box 43, initially limiting the limiting box 43. Then, the threaded column 42 is rotated to make the outside of the threaded column 42 snap into the inside of the limiting box 43, thereby fixing the snapping state of the clamp 35 and the fixed box 36. This prevents the clamp from loosening due to vibration and shaking during normal use, which would affect the tightening operation of the pipe body 2. In industrial production, pipelines are often subjected to various vibrations and external forces. The setting of the limiting mechanism 4 effectively solves the problem of clamp loosening and ensures the stability and safety of the pipeline connection.

[0045] Specifically, after the clamp is initially tightened, rotate the two rotating rods 41 to make them fit against the outside of the limiting box 43, thus initially limiting the limiting box 43. Then rotate the threaded post 42 to make the threaded post 42 engage inside the limiting box 43, further fixing the engagement state of the clamp post 35 and the fixing box 36, preventing the clamp from loosening when the pipeline is vibrated or shaken, and ensuring that the pipe body 2 is securely and reliably fastened.

[0046] Working principle: When the operator needs to tighten the clamp 1, the clamp 1 and the outer part of the sliding band 31 are placed on the outside of the pipe body 2. At this time, the clamp is used to clamp the outside of the fixing box 36 and the limiting box 43, so that the sliding band 31 and the clamping band 32 slide inside the clamp 1, so that the sliding band 31 and the clamp 1 are tightly pressed against the outside of the pipe body 2, until the clamping post 35 is locked inside the fixing box 36 as the clamp 1 moves, completing the tightening operation of the pipe body 2. When the clamp 1 is pulled, the squeezing part 372 will generate elasticity, thereby preventing the sliding band 31 from deforming and bulging upward under force, which would cause gaps between the clamp and the surface of the pipe body 2 and affect the sealing effect. The sliding of the two sets of clamping bands 32 and the locking of the clamping post 35 prevent excessive pulling force on one side during installation, which would cause the clamp to deform as a whole.

[0047] After the clamp is installed, the rotating rod 41 is rotated to make it fit against the outside of the limiting box 43. Then, the threaded post 42 is rotated to make the outside of the threaded post 42 engage with the inside of the limiting box 43, thereby fixing the engagement state of the clamp post 35 and the fixing box 36. This prevents the clamp from loosening due to vibration and shaking during normal use, which would affect the tightening operation of the pipe body 2.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
