Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a stainless steel U-bolt. Background Technology

[0002] U-bolts are mechanical fasteners shaped like the letter "U". Due to their threaded ends and rounded middle, they are commonly used to secure pipes, steel structures, and machinery. Through the cooperation of a nut and washer, they clamp and fix the connected parts. Their core function is to utilize the clamping force of the U-shaped structure to limit and fasten objects, making them suitable for applications requiring tensile loads or vibration.

[0003] However, traditional U-bolts have a fixed bottom structure, making it difficult to adapt to different shaped mounting surfaces. For example, when facing flat or curved surfaces, their bottom structure cannot be adapted to different mounting surfaces (flat or curved). During construction, it is necessary to prepare multiple specifications of U-bolts in advance according to the actual scenario, or temporarily find suitable models and replace different types of bolts, resulting in low installation efficiency. Therefore, a stainless steel U-bolt is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a stainless steel U-bolt, which aims to improve the problem of low installation efficiency caused by the need to frequently change different specifications to adapt to flat or curved surface installation requirements due to the fixed bottom structure of traditional U-bolts in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stainless steel U-bolt, comprising two sets of limiting posts, the outer walls of the two sets of limiting posts being detachably fitted with washers, and the bottom inner walls of the two sets of limiting posts being jointly provided with an adjustment mechanism;

[0006] The adjustment mechanism includes a positioning column fixedly connected to the inner wall of the bottom of the limiting column, a rotating column rotatably connected to the outer wall of the positioning column, a right-angle column fixedly connected to the side of the rotating column away from the positioning column, an arc-shaped column fixedly connected to the inner surface of the right-angle column, and a connecting mechanism provided at the top of the limiting column.

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

[0008] The positioning column and the rotating column are connected by bolts.

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

[0010] The outer wall of the rotating column is rotatably connected to the inner wall of the bottom of the limiting column.

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

[0012] The cross-section of the positioning post is set in an I-shape.

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

[0014] The connecting mechanism includes a positioning nut threaded to the top of a set of limiting posts, a connecting plate hinged to the right side of the positioning nut, a connecting nut threaded to the top of another set of limiting posts, a concave block fixedly connected to the outer wall of the connecting nut, and the right side of the connecting plate snapping into the inner wall of the concave block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the cooperation between the limiting column, the gasket and the adjustment mechanism, when adjustment is needed, the rotation of the column can quickly switch the right-angle column or the arc column to face upwards. It can adapt to different installation surfaces such as flat and arc surfaces without replacing the U-bolt, improve the overall installation operation, and effectively avoid the delay in construction period and the chaos in material management caused by frequent bolt replacement.

[0017] 2. In this utility model, through the mutual cooperation between the connecting mechanism and other structures, and the snap-fit ​​design of the positioning nut, connecting nut and connecting plate, the two sets of limiting columns form a stable linkage structure. Combined with the anti-loosening guarantee of the I-shaped positioning column and bolt in the adjustment mechanism, the overall stability is improved under complex working conditions such as vibration and impact, and the long-term stability of the fixed parts is ensured.

[0025] 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.

[0026] Reference Figures 1-2 This utility model provides an embodiment of a stainless steel U-bolt, comprising two sets of limiting posts 1. The top of each set of limiting posts 1 is provided with a threaded groove, and the bottom is cylindrical. Both sets of limiting posts 1 are made of stainless steel. The outer walls of both sets of limiting posts 1 are detachably fitted with washers 2. The washers 2 can increase the contact surface with the connecting parts, thereby increasing stability. The bottom inner walls of both sets of limiting posts 1 are jointly provided with an adjustment mechanism 3. The bottom of the stainless steel U-bolt can be quickly adjusted by the adjustment mechanism 3, thereby improving work efficiency. The cooperation of the two sets of limiting posts 1 and their adjustment mechanism 3 forms the stainless steel U-bolt.

[0027] Reference Figures 2-4 The adjustment mechanism 3 includes a positioning column 304 fixedly connected to the inner wall of the bottom of the limiting column 1. A rotating column 303 is rotatably connected to the outer wall of the positioning column 304. The positioning column 304 can support the rotating column 303. A right-angle column 301 is fixedly connected to the side of the rotating column 303 away from the positioning column 304. An arc-shaped column 302 is fixedly connected to the inner surface of the right-angle column 301. By rotating the rotating column 303, the right-angle column 301 or the arc-shaped column 302 can be set upward, which facilitates installation and adjustment. A connecting mechanism 4 is provided at the top of the limiting column 1. The connection mechanism 4 can improve the overall stability of the limiting column 1 after installation.

[0028] Reference Figures 2-4 The positioning column 304 and the rotating column 303 are connected by bolts 305. The bolts 305 make the rotating column 303 more stable after installation. The outer wall of the rotating column 303 is rotatably connected to the inner wall of the bottom of the limiting column 1. The rotation setting avoids motion interference. The cross-section of the positioning column 304 is set in the shape of an I-beam. The I-beam setting prevents the rotating column 303 from falling off when rotating.

[0029] Reference Figure 1 and Figure 5The connecting mechanism 4 includes a positioning nut 401 threadedly connected to the top of a set of limiting posts 1. A connecting plate 402 is hinged to the right side of the positioning nut 401, and the two move in the same direction. A connecting nut 403 is threadedly connected to the top of another set of limiting posts 1. A concave block 404 is fixedly connected to the outer wall of the connecting nut 403. Multiple sets of concave blocks 404 are provided. The right side of the connecting plate 402 is engaged with the inner wall of the concave block 404. A ball hole is provided on the inner wall of the concave block 404, and a plastic ball is provided on the right side of the connecting plate 402. The connecting plate 402 and the connecting nut 403 are engaged and connected by the engagement of the plastic ball and the ball hole.

[0030] Working principle: Installation and adjustment are achieved through the adjustment mechanism 3 at the bottom of two sets of stainless steel limit posts 1. During adjustment, the rotating post 303 is rotated to make it rotate around the positioning post 304, thereby causing the right-angle post 301 or the arc post 302 to face upwards to adapt to different installation scenarios. During installation, the adjustment mechanism 3 at the bottom of the limit post 1 is first adjusted to the required state. The contact area with the connecting parts is increased by the shim 2, and then the connecting mechanism 4 is used for fixing. That is, the top of one set of limit posts 1 is screwed into the positioning nut 401, and the other set is screwed into the connecting nut 403. Then, the hinge end of the connecting plate 402 is connected to the positioning nut 401, and the plastic ball at the other end is inserted into the ball hole of the concave block 404 on the connecting nut 403, so that the two sets of limit posts 1 are linked through the connecting plate 402, thereby improving the overall stability. At the same time, the I-shaped cross section of the positioning post 304 in the adjustment mechanism 3 can prevent the rotating post 303 from falling off when rotating, and the bolt 305 ensures that the rotating post 303 is stable after installation.

[0031] 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.
