Description

Technical Field

[0001] This utility model relates to the field of locking components technology, and in particular to a long-life locking component. Background Technology

[0002] Locking components are parts or devices used to fix or lock other mechanical parts. They are typically used to connect and secure components to prevent them from loosening due to vibration or impact during operation. Spring locking components are mechanical elements that utilize the elasticity and pressure characteristics of springs to achieve locking or fixing functions, effectively maintaining the stability and reliability of the connection.

[0003] The above-mentioned and existing technologies have the following defects: During long-term use, due to long-term load and stress, the spring may undergo permanent deformation, resulting in weakened elasticity and inability to effectively provide locking force, which may lead to loosening, detachment or failure of mechanical parts, and in severe cases may cause equipment failure or safety accidents.

[0004] Therefore, a long-life locking component is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that locking components use springs for compression, and that springs may lose their elasticity over time under certain circumstances, and to propose a long-life locking component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a long-life locking component, comprising a top plate and a bottom plate, wherein a cylinder is fixedly connected to one side of the top plate, a round rod slides through the surface of the top plate, the round rod slides through the cylinder, a locking rod is fixedly connected to the surface of the round rod, a through hole is provided on the surface of the bottom plate, the size of the through hole is adapted to the size of the locking rod and the round rod, a round plate is fixedly connected to one end of the round rod, a locking structure is provided on the surface of the round rod, the locking structure includes a threaded groove, the threaded groove is opened on the arc surface of the round rod, an internally threaded tube is threadedly connected to the surface of the threaded groove, and a limit plate is fixedly connected to one end of the internally threaded tube.

[0007] The effect achieved by the above components is that by setting a locking structure, the threads can provide a more stable fixing effect because they generate friction through rotational tightening, while springs may lose elasticity over time in some cases, thus ensuring the stability of the locking components.

[0008] Preferably, a plurality of protective pads are glued to the side of the limiting plate near the top plate, and the protective pads are made of rubber.

[0009] The effect achieved by the above components is that the limiting plate will cause the protective pad to adhere to the surface of the top plate, and the protective pad will provide a buffer distance between the limiting plate and the top plate, thereby preventing damage to the thread teeth when the equipment shakes violently.

[0010] Preferably, the circular rod has several handles fixedly connected to its arc surface.

[0011] The effect achieved by the above components is that the rotation of the round rod will drive the limit plate to rotate, and the round rod will facilitate the rotation of the limit plate.

[0012] Preferably, the top plate and the bottom plate are each fixedly connected with a number of anti-slip protrusions on the side closest to each other.

[0013] The effect achieved by the above components is that the anti-slip protrusions on the surfaces of the bottom plate and top plate increase the friction between them and the equipment, thereby preventing the top plate and bottom plate from rotating on the surface of the equipment.

[0014] Preferably, the bottom plate has a tapered groove on the side near the top plate, and the tapered groove is connected to the through hole.

[0015] The effect achieved by the above components is that the round rod will drive the locking rod to slide into the conical groove. Continue installing the round rod until the round rod drives the locking rod through the through hole. The conical groove facilitates the round rod to drive the locking rod into the through hole.

[0016] Preferably, the surface of the base plate is provided with an arc-shaped groove, which is connected to a through hole.

[0017] The effect achieved by the above components is that the round rod will drive the locking rod to slide into the arc-shaped groove, and the arc-shaped groove will reach the position of the locking rod, thus preventing the locking rod from sliding on the surface of the base plate.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting a locking structure, the cylinder is inserted into the mounting hole, and then the base plate is placed below the mounting hole. Then, the round rod is pressed, and the round rod will slide inside the top plate and the cylinder. The movement of the round rod will drive the locking rod to move until the round rod drives the locking rod through the through hole. Then, the round plate is rotated, and the rotation of the round plate will drive the rotation of the round rod, which in turn will drive the locking rod to rotate. When the locking rod rotates to a suitable angle, the limiting plate is rotated, and the rotation of the limiting plate will drive the rotation of the internal threaded tube. The rotation of the internal threaded tube will move on the surface of the round rod with the help of the thread and the thread groove. When the limiting plate moves to a suitable position, the limiting plate will fit against the surface of the top plate. Continue to rotate the limiting plate, and the internal threaded tube will drive the round rod to move inside the top plate and the cylinder. The movement of the round rod will drive the base plate to move with the help of the locking rod until the base plate is tightly fitted against the surface of the equipment. Thus, the locking component is used to lock the equipment. The threads can provide a more stable fixing effect because they form friction through rotational tightening, while springs may lose elasticity over time in some cases, thereby ensuring the stability of the locking component.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1 - Figure 4 As shown, this utility model provides a long-life locking component, including a top plate 1 and a bottom plate 6. A cylinder 2 is fixedly connected to one side of the top plate 1. A round rod 3 slides through the surface of the top plate 1 and through the cylinder 2. A locking rod 4 is fixedly connected to the surface of the round rod 3. A through hole 7 is provided on the surface of the bottom plate 6. The size of the through hole 7 is adapted to the size of the locking rod 4 and the round rod 3. A round plate 5 is fixedly connected to one end of the round rod 3. A locking structure 8 is provided on the surface of the round rod 3. By setting the locking structure 8, the threads can provide a more stable fixing effect because they generate friction through rotational tightening, while springs may lose elasticity over time in some cases, thus ensuring the stability of the locking component.

[0028] The specific settings and functions of its locking structure 8 will be explained below.

[0029] like Figure 2 and Figure 3 and Figure 4 As shown, the locking structure 8 includes a threaded groove 81, which is formed on the arc surface of the round rod 3. An internally threaded tube 82 is threadedly connected to the surface of the threaded groove 81, and one end of the internally threaded tube 82 is fixedly connected to a limiting plate 83. Several protective pads 84, made of rubber, are glued to the side of the limiting plate 83 closest to the top plate 1. The limiting plate 83 causes the protective pads 84 to adhere to the surface of the top plate 1, providing a buffer distance between the limiting plate 83 and the top plate 1, thus preventing damage to the threads due to violent shaking of the equipment. Several handles 85 are fixedly connected to the arc surface of the round rod 3. Rotation of the round rod 3 causes the limiting plate 83 to rotate, facilitating the rotation of the limiting plate 83. Several anti-slip protrusions 86 are fixedly connected to the sides of the top plate 1 and the bottom plate 6 closest to each other. The anti-slip protrusions 86 on the surfaces of the base plate 6 and the top plate 1 increase the friction between them and the equipment, thus preventing the top plate 1 and the base plate 6 from rotating on the surface of the equipment. A tapered groove 87 is formed on the side of the base plate 6 closest to the top plate 1, and the tapered groove 87 is connected to the through hole 7. The round rod 3 will drive the locking rod 4 to slide into the tapered groove 87. The round rod 3 continues to be installed until it drives the locking rod 4 through the through hole 7. The tapered groove 87 facilitates the round rod 3 driving the locking rod 4 into the through hole 7. An arc-shaped groove 88 is formed on the surface of the base plate 6, and the arc-shaped groove 88 is connected to the through hole 7. The round rod 3 will drive the locking rod 4 to slide into the arc-shaped groove 88, where the arc-shaped groove 88 reaches the position of the locking rod 4, preventing the locking rod 4 from sliding on the surface of the base plate 6.

[0030] The overall working principle is as follows: When using the locking mechanism, first rotate the round rod 3. The rotation of the round rod 3 will drive the limit plate 83 to rotate, which in turn will drive the internal thread tube 82 to rotate. The internal thread tube 82 will move on the surface of the round rod 3 with the help of the thread and the thread groove 81. The internal thread tube 82 will move closer to the round plate 5. When the internal thread tube 82 moves to the appropriate position, insert the cylinder 2 into the mounting hole, then place the base plate 6 below the mounting hole, and then press the round rod 3. The round rod 3 will slide in the top plate 1 and the cylinder 2. The movement of the round rod 3 will drive the locking rod 4 to move. During the movement, the round rod 3 will drive the locking rod 4 to slide into the conical groove 87. Continue to install the round rod 3 until the round rod 3 drives the locking rod 4 through the through hole 7. The conical groove 87 facilitates the round rod 3 to drive the locking rod 4 to slide into the through hole 7. Then rotate the round plate 5. The rotation of the round plate 5 will drive the round rod 3 to rotate, which in turn will drive the locking rod 4 to rotate. When the locking rod 4 rotates to the appropriate angle... Then, pull the round rod 3. The round rod 3 will drive the locking rod 4 to slide into the arc groove 88. The arc groove 88 reaches the position of the locking rod 4, preventing the locking rod 4 from sliding on the surface of the base plate 6. At this time, the top plate 1 will be attached to the surface of the locking device. Then rotate the round rod 3. The rotation of the round rod 3 will drive the limit plate 83 to rotate. The rotation of the limit plate 83 will drive the internal thread tube 82 to rotate. The rotation of the internal thread tube 82 will move on the surface of the round rod 3 with the help of the thread and the thread groove 81. When the limit plate 83 moves to the appropriate position, the limit plate 83 will drive the protective pad 84 to be attached to the surface of the top plate 1. Continue to rotate the limit plate 83. The internal thread tube 82 will drive the round rod 3 to move in the top plate 1 and the cylinder 2. The movement of the round rod 3 will drive the base plate 6 to move with the help of the locking rod 4 until the base plate 6 is tightly attached to the surface of the equipment. The anti-slip protrusions 86 on the surface of the base plate 6 and the top plate 1 will increase the friction between the base plate 6 and the equipment, thereby preventing the top plate 1 and the base plate 6 from rotating on the surface of the equipment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
