Description

Technical Field

[0001] This utility model relates to the field of ring hoop technology, and in particular to a double positioning hole ring hoop for preventing loosening. Background Technology

[0002] A hose clamp is a type of stainless steel hose clamp made using a hollow stamping process. Its function is to ensure a tight seal at pipe connections. It is commonly found in water, oil, and air lines in vehicles such as automobiles, motorcycles, and trailers. It can also be used in equipment such as food and chemical machinery. Hoses have advantages such as strong locking force and precise engagement.

[0003] However, current hoop assembly suffers from inconsistent results due to the lack of fixed positioning. This necessitates manual tightening and requires adjustment of the hoop's orientation, causing operational inconvenience. Furthermore, after assembly, the locking bolts used for tightening may loosen due to external vibrations, affecting the seal at the pipe connection.

[0004] In view of the above problems, it is necessary to optimize and improve the traditional ring hoop, and propose a double positioning hole ring hoop to prevent loosening. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a double-positioning hole ring clamp to prevent loosening. The double positioning holes limit the position of the ring clamp and prevent it from shifting during tightening. Furthermore, a limiting component is added to the operating end of the locking bolt to effectively prevent the locking bolt from loosening and rotating, thereby enhancing the stability of the ring clamp during tightening.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A double-positioning-hole anti-loosening hoop, characterized in that it comprises a hoop band, a hoop housing, a locking bolt, and a limiting component. The hoop band has a hoop housing at one end, and a locking bolt is disposed within the hoop housing. A locking groove is provided on the hoop band at the end furthest from the hoop housing, and this end passes through and extends out of the hoop housing. The operating end of the locking bolt passes through and extends out from a fixing plate disposed on one side of the hoop housing. A limiting component for limiting the locking bolt is provided on the operating end. The hoop band has a first positioning hole and a second positioning hole for positioning.

[0008] The limiting assembly consists of a toothed ring, a limiting ring, and a locking rod. The toothed ring is sleeved and fixed on the operating end. The toothed ring has protruding teeth. The inner wall of the limiting ring has a toothed groove. The toothed groove and the protruding teeth are adapted to fit the limiting ring onto the toothed ring. The outer wall of the limiting ring has a locking rod. The front end of the locking rod engages with a slot on the fixing plate of the hoop.

[0009] The first positioning hole is formed by connecting oblong hole A and oblong hole B through an arc transition line.

[0010] The second positioning hole is formed by the transitional connection of an elongated hole C and an elongated hole D.

[0011] Furthermore, the operating end is provided with a groove in the shape of an "I", and the operating end can be rotated with a flathead screwdriver to achieve tightening.

[0012] Furthermore, the locking bolt is adapted to the locking groove on the hoop.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a first positioning hole and a second positioning hole on the hoop, so that the hoop can be installed at the corresponding boss position on the matching rubber tube during assembly, thereby limiting and fixing the position of the hoop and the direction of the hoop housing, preventing the hoop from shifting during assembly, eliminating the need for manual tightening and adjusting the direction of the hoop, making operation convenient.

[0015] This invention features a limiting component at the operating end of the locking bolt. After the locking bolt is rotated to tighten the ring, the limiting ring is fitted onto the toothed ring at the operating end by matching the groove on the limiting ring with the protruding teeth on the toothed ring. Furthermore, multiple sets of locking rods on the outer wall of the limiting ring engage with the slots on the fixing plate of the ring housing, thereby limiting and fixing the position of the limiting ring, which in turn limits and fixes the position of the locking bolt, reducing the problem of the ring loosening due to the locking bolt rotating loosely.

[0024] Example 1

[0025] like Figure 3 As shown, a hoop shell 2 is provided at one end of the hoop 1. A locking bolt is provided inside the hoop shell 2. The operating end 31 of the locking bolt passes through and extends from the fixing plate 21 provided on one side of the hoop shell 2. A groove 311 with an "I" shape is provided on the operating end 31. The operating end can be rotated by a flathead screwdriver to tighten the hoop.

[0026] A locking groove 11 is provided on the end of the hoop 1 that is away from the hoop housing 2, and this end passes through and extends out of the hoop housing 2. The locking bolt in the hoop housing 2 is adapted to the locking groove 11 on the hoop 1, so that the hoop can be tightened by rotating the locking bolt.

[0027] like Figure 1 and 2 The hoop 1 is provided with a first positioning hole 12 and a second positioning hole 13 for positioning. The first positioning hole 12 is formed by connecting oblong holes A (121) and B (122) through an arc transition line 123. The second positioning hole 13 is formed by connecting oblong holes C (131) and D (132). As can be seen from the figure, the size of oblong hole A (121) is larger than that of oblong hole B (122), and the size of oblong hole C (131) is larger than that of oblong hole D (132). The first positioning hole 12 and the second positioning hole 13 allow the hoop to be installed at the corresponding boss position on the matching hose during assembly, thereby limiting and fixing the position of the hoop and the direction of the hoop housing. This prevents the hoop from shifting during assembly and eliminates the need for manual adjustment of the hoop's direction when tightening, making the operation convenient.

[0028] like Figure 3 and 4 A limiting component for limiting the locking bolt is provided on the operating end 31 of the locking bolt. The limiting component consists of a toothed ring 4, a limiting ring 5, and a locking rod 6. The toothed ring 4 is sleeved and fixed on the operating end 31, and the toothed ring 4 is provided with protruding teeth 41. The inner wall of the limiting ring 5 is provided with a toothed groove 51. The toothed groove 51 and the protruding teeth 42 are adapted to fit the limiting ring 5 onto the toothed ring 4. A locking rod 6 is provided on the outer wall of the limiting ring 5. The front end of the locking rod 6 is engaged with the locking groove 211 provided on the fixing plate 21 of the hoop 2.

[0029] When the hoop needs to be tightened, the limiting ring 5 must be removed before the operating end 31 can be rotated using a tightening tool to rotate the locking bolt and complete the hoop tightening operation. After tightening, the limiting ring 5 is fitted onto the toothed ring 4 of the operating end 31 by matching the toothed groove 51 on the limiting ring 5 with the toothed protrusion 41 on the toothed ring 4. The multiple sets of locking rods 6 provided on the outer wall of the limiting ring 51 are engaged with the locking grooves 211 on the fixing plate 21 of the hoop housing 2, thereby limiting and fixing the position of the limiting ring 5, and thus limiting and fixing the position of the locking bolt, reducing the problem of the hoop loosening due to the locking bolt rotating.

[0030] It should be noted that after rotating the operating end 31 during the tightening process, the new tooth phase of the toothed ring 4 should still be aligned with the tooth groove 51 on the limiting ring 5.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
