A load-bearing mechanism for long springs

Abstract

This utility model discloses a support mechanism for long springs, including a mounting column and an extension assembly. The mounting column has a first V-shaped strip at its top. The extension assembly includes two extension columns, each with a rotating bolt on one side edge and rotating grooves on both sides edge of the mounting column. This utility model extends the first V-shaped strip by using a second V-shaped strip to support springs of different lengths. When the extension column is extended, a limiting rod engages with a limiting port, i.e., the mounting spring pushes the limiting rod into the limiting port, thus fixing the position of the extension column. A caster wheel supports the outer side of the extension column, ensuring its stability. Furthermore, when supporting the spring, there is only a certain gap between the first and second V-shaped strips, ensuring support for the spring and preventing sagging of unsupported parts of the spring due to a large gap.

Description

Technical Field

[0001] This utility model relates to the field of long spring detection technology, specifically a bearing mechanism for long springs. Background Technology

[0002] Long spring testing is a systematic inspection of the performance, quality, and safety of long springs. Its core purpose is to ensure that the spring functions stably during use, such as bearing specified loads and maintaining its elastic deformation capacity. Testing typically includes dimensional accuracy, appearance quality, mechanical properties, and environmental resistance under certain special conditions. Through specialized instruments and standardized procedures, problems with the springs can be identified promptly, ensuring their reliable operation in automotive, machinery, and rail transportation applications.

[0003] The existing Chinese patent publication number CN220660595U, entitled "A Support Mechanism for Long Springs," explicitly states in its abstract that "This utility model discloses a support mechanism for long springs, comprising: a base plate with a guide rail; a fixed support fixed to the base plate and located at one end of the guide rail, the fixed support having a first support member; multiple movable supports slidably connected to the guide rail, each movable support having a second support member; a telescopic mechanism, one end of which is connected to the fixed support, the telescopic mechanism connecting the multiple movable supports to drive the movable supports to move on the guide rail; and a drive mechanism, the other end of which is connected to the drive mechanism, the drive mechanism driving the telescopic mechanism to extend and retract, thereby moving the movable supports. This solution is applicable to the support of various long springs of different lengths."

[0004] However, in this technology, the spacing of the movable supports is adjusted synchronously by the telescopic mechanism, thus making it suitable for bearing various long springs of different lengths. However, springs with different length-to-diameter ratios have different requirements for the spacing of the support points. Springs with larger length-to-diameter ratios require denser support points. Multiple movable supports bear the load of long springs of different lengths by adjusting their spacing with each other. After the movable supports are adjusted, and when the spacing between the movable supports is too large, it may cause the unsupported part in the middle of the spring to sag, affecting the morphological stability during testing. Utility Model Content

[0005] The purpose of this invention is to provide a bearing mechanism for long springs, in order to solve the problem mentioned in the background art that springs with different length-to-diameter ratios have different requirements for the spacing of support points, and that when the spacing between the movable supports is too large, the unsupported part in the middle of the spring may sag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A load-bearing mechanism for a long spring includes a mounting post and an extension assembly, wherein a first V-shaped strip is provided at the top of the mounting post; The extension assembly includes two extension posts, with a rotating bolt at one edge of each extension post and rotating grooves at both edges of the mounting posts.

[0007] In a preferred embodiment of this utility model, a second V-shaped strip is provided at the top of the extension column, and the rotating bolt is rotatably connected to the rotating groove.

[0008] In a preferred embodiment of this utility model, magnetic blocks are provided on the front and rear sides of the mounting column, the front and rear sides of the extension column are made of magnetically attractable metal, and the extension column and the magnetic blocks are magnetically connected.

[0009] In a preferred embodiment of this utility model, sliding grooves are provided on both sides of the outer side of the mounting column, and a limit rod is slidably arranged inside the sliding groove.

[0010] In a preferred embodiment of this utility model, a limiting port is provided on one side of the bottom of the extension column, and the top of the limiting rod is installed and removed in the limiting port.

[0011] In a preferred embodiment of the present invention, a mounting spring is provided at the bottom of the inner side of the slide groove, a limiting rod is connected to the top of the mounting spring, a pull rod is provided at the bottom of the limiting rod, and the pull rod extends to the bottom of the outer side of the slide groove.

[0012] In a preferred embodiment of this utility model, a mounting plate is provided at the bottom of the mounting column, and a support column is provided at the bottom of the mounting plate.

[0013] In a preferred embodiment of this utility model, a caster wheel is provided at the bottom of the outer side of the extension column, and the bottom of the caster wheel is flush with the bottom of the support column.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0015] Beneficial effects: The first V-shaped bar supports the long spring. By rotating the extension columns on both sides, the extension columns unfold to the left and right sides of the mounting column. At this time, the second V-shaped bar can be used to lengthen the first V-shaped bar, thereby supporting springs of different lengths. When the extension column is unfolded, the limiting rod aligns with the limiting port. That is, the mounting spring pushes the limiting rod into the limiting port, thereby fixing the position of the extension column. The universal wheels support the outside of the extension column, thus ensuring the stability of the extension column. Furthermore, when supporting the spring, there is only a certain gap between the first V-shaped bar and the second V-shaped bar, which ensures the support of the spring and prevents the unsupported parts of the spring from sagging due to a large gap.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please refer to Figures 1-4This utility model discloses a bearing mechanism for a long spring, comprising a mounting post 1 and an extension assembly. The mounting post 1 is a mounting structure used to install other structures. A first V-shaped strip 11 is provided at the top of the mounting post 1, which bears the long spring. The extension assembly includes two extension posts 2, which are located on both sides of the mounting post 1 and are used to extend the mounting post 1. A rotating bolt 21 is provided at one edge of the extension post 2, and rotating grooves 12 are provided at the two edges on both sides of the mounting post 1. The rotating bolt 21 and the rotating groove 12 are rotatably connected, that is, the rotating bolt 21 is locked in the rotating groove 12 and rotates. The two rotating grooves 12 are located on the front and rear sides, so that the two extension posts 2 rotate towards the front and rear sides of the mounting post 1 respectively, avoiding mutual interference caused by rotating forward or backward. Furthermore, due to the structural limitations of the mounting post 1 and the extension post 2 themselves, the extension post 2 can only rotate 180°.

[0021] The extension column 2 can be rotated to the front / back or left / right sides of the mounting column 1. When rotated to the front / back or left / right sides of the mounting column 1, it is in the retracted state, while when rotated to the left / right sides, it is in the extended state. Figure 1 In its unfolded state, the extension column 2 has a second V-shaped strip 22 at its top. When the extension column 2 is unfolded, the second V-shaped strip 22 extends the first V-shaped strip 11, thereby supporting springs of different lengths. When supporting the springs, there is only a certain gap between the first V-shaped strip 11 and the second V-shaped strip 22, ensuring support for the springs and preventing the unsupported parts of the springs from sagging due to large gaps. Magnetic blocks 13 are provided on the front and rear sides of the mounting column 1. The front and rear sides of the extension column 2 are made of magnetically adsorbable metal. The extension column 2 and the magnetic blocks 13 are magnetically connected. When the extension column 2 is retracted, the sidewalls of the extension column 2 are adsorbed onto the magnetic blocks 13, thereby ensuring the stability of the extension column 2.

[0022] The mounting column 1 has sliding grooves 3 on both sides of its exterior. A limiting rod 32 slides inside the sliding grooves 3. A limiting port 23 is located on one side of the bottom of the extension column 2. The top of the limiting rod 32 is installed and removed within the limiting port 23. A mounting spring 31 is located at the bottom of the inner side of the sliding groove 3. The top of the mounting spring 31 is connected to the limiting rod 32, and the mounting spring 31 always pushes the limiting rod 32. A pull rod 33 is located at the bottom of the limiting rod 32, extending to the bottom of the outer side of the sliding groove 3. When the extension column 2 is extended, the limiting rod 32 aligns with the limiting port 23, i.e., the mounting spring 31 pushes the limiting rod 32 into the limiting port 23, thus fixing it in place. The position of the extension column 2 is determined, and the limiting rod 32 can be pulled by the bottom pull rod 33 to enter the slide groove 3, that is, to be disassembled in the limiting port 23. The bottom of the mounting column 1 is provided with a mounting plate 14, which is a mounting structure used to install the mounting column 1. The bottom of the mounting plate 14 is provided with a support column 34, which is supported on the ground. The bottom of the outer side of the extension column 2 is provided with a caster wheel 24, the bottom of the caster wheel 24 is flush with the bottom of the support column 34, that is, both are in contact with the ground. When the extension column 2 is extended, the caster wheel 24 supports the outer side of the extension column 2, thereby ensuring the stability of the extension column 2.

[0023] The working principle of this utility model is as follows: the long spring is supported by the first V-shaped strip 11. By rotating the extension columns 2 on both sides, the extension columns 2 are extended to the left and right sides of the mounting column 1. At this time, the first V-shaped strip 11 can be lengthened by the second V-shaped strip 22, thereby supporting springs of different lengths. When supporting the spring, there is only a certain gap between the first V-shaped strip 11 and the second V-shaped strip 22, which ensures the support of the spring and avoids the spring from sagging due to the unsupported part due to the large gap. When the extension column 2 is extended, the limiting rod 32 is connected to the limiting port 23. That is, the limiting rod 32 is pushed into the limiting port 23 by the mounting spring 31, thereby fixing the position of the extension column 2. The outer side of the extension column 2 is supported by the universal wheel 24, thereby ensuring the stability of the extension column 2.
