This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0020] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "arranged", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0021] First, refer toFigure 1-2 Describe the clamping device of the present utility model. Figure 1 It is a structural diagram of the clamping device of the present utility model; Figure 2 It is a structural diagram of the first clamping mechanism of the present utility model.
[0022] Based on the problem of easy leakage at the existing pipe joints pointed out in the background art, the clamping device of the present utility model includes a first clamping mechanism 1 and a second clamping mechanism 2. The first clamping mechanism 1 and the second clamping mechanism 2 are symmetrically arranged up and down, and both include a clamping piece 31 and a sealing ring 34. The clamping area formed by the two clamping pieces 31 can clamp the pipe; a convex ring 32 is arranged at the middle part of the inner wall of the clamping piece 31, and the convex ring 32 surrounds the inner wall of the clamping piece 31, and sealing rings 34 are arranged on the inner walls of the clamping pieces 31 on both sides of the convex ring 32.
[0023] In this application, by arranging a convex ring 32 at the middle position of the inner walls of the two clamping pieces 31, the clamping space formed by the first clamping mechanism 1 and the second clamping mechanism 2 is divided into two clamping areas, which can respectively clamp two independent pipes. In addition, by arranging sealing rings 34 on the clamping pieces 31 on both sides of the convex ring 32, the sealing rings 34 can improve the sealing performance between the clamping device and the clamped pipe, thereby improving the sealing effect at the pipe joint and avoiding the problem of leakage at the pipe joint.
[0024] Next, further refer to Figure 1-2 to introduce a preferred implementation manner of the clamping device of this application. Those skilled in the art can understand that the implementation manner introduced below is only used to illustrate the principle of this application and is not intended to limit the protection scope of this application. On the premise that the clamping device includes at least a first clamping mechanism 1 and a second clamping mechanism 2, those skilled in the art can adjust the following setting manners so that this application can be applied to more specific application scenarios.
[0025] See Figure 1 , the clamping device includes a first clamping mechanism 1, a second clamping mechanism 2 and a fastener. The first clamping mechanism 1 and the second clamping mechanism 2 are symmetrically arranged up and down.
[0026] Then see Figure 1-2 , the structures of the first clamping mechanism 1 and the second clamping mechanism 2 are the same, and both include a clamping piece 31, a connecting plate 33, a sealing ring 34 and a convex ring 32. The inner and outer longitudinal sections of the clamping piece 31 are both semi-circular, and connecting plates 33 are arranged on both sides (such as Figure 1 shown as the left and right sides) in the length direction of the clamping piece 31, and the two connecting plates 33 are arranged to extend away from the clamping piece 31 along the outside of the clamping piece 31, and the two connecting plates 33 are symmetrically arranged with respect to the length direction of the clamping piece 31. And in the length direction of the two connecting plates 33 (such asFigure 1 The length in the front - rear direction (as shown) is equal to the length in the length direction of the clamping piece 31 (such as Figure 1 the front - rear direction shown). Four connection holes are provided on each connecting plate 33, and the four connection holes are arranged at intervals along the length direction of the connecting plate 33. The four connection holes on the connecting plates 33 of the two clamping mechanisms are vertically corresponding, and they are connected by fastening screws 4 so that the first clamping mechanism 1 and the second clamping mechanism 2 can clamp and fix the pipeline. The connecting plate 33 is flush with the side surface in the height direction of the clamping piece 31 (such as Figure 1 the upper side shown).
[0027] Of course, the cross - sectional shape of the clamping piece 31 in this application is not fixed, and those skilled in the art can adjust it according to needs. For example, the outer longitudinal section of the clamping piece 31 can be rectangular. In addition, the number of connection holes on the connecting plate 33 in this application is not fixed, and those skilled in the art can adjust it according to needs. For example, the number of connection holes can be 2, 3 or other numbers.
[0028] It should be noted that gaskets can be provided on the inner sides of the two connecting plates 33 to improve the connection firmness of the two clamping mechanisms to the pipeline.
[0029] Then refer to Figure 1 again. A convex ring 32 is provided at the middle position on the inner side of the clamping piece 31. The cross - section of the convex ring 32 is semi - circular, and the convex ring 32 surrounds the inner wall of the clamping piece 31. Both ends in the axial direction of the convex ring 32 (such as Figure 2 the front and rear sides shown) are provided with annular grooves 321, and the outer diameter of the annular groove 321 is the same as the inner diameter of the clamping piece 31 so that part of the sealing ring 34 can be inserted therein. Sealing rings 34 are provided on the inner walls of the clamping piece 31 on both sides of the convex ring 32. The setting of the sealing ring 34 can, on the one hand, improve the sealing performance between the pipeline and the clamping device, and on the other hand, can also improve the connection strength of the clamping device to the pipeline. The inner diameter of the sealing ring 34 is less than or equal to the inner diameter of the convex ring 32.
[0030] It should be noted that in other preferred embodiments, the inner diameter of the sealing ring 34 can also be greater than the inner diameter of the annular groove 321, so that part of the pipeline and the sealing ring 34 can be inserted into the annular groove 321, improving the sealing performance between the pipeline and the clamping device and avoiding leakage problems at the connection during the pipeline connection process.
[0031] In addition, the setting of the annular grooves 321 on both sides in the axial direction of the convex ring 32 is not necessary, and those skilled in the art can choose according to needs.
[0032] In addition, this application can also be provided with connection seats on the outer wall of the clamping piece 31 so that the clamping device can be fixed on the wall or other substrates through the connection seats to improve the connection stability of the two connected pipelines.
[0033] The technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
