Description

Technical Field

[0001] This utility model relates to the field of spring technology, and in particular to a spring assembly auxiliary device. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Made of elastic material, it deforms under external force and returns to its original shape after the force is removed. It is also called a "spring". They are generally made of spring steel. Springs come in a wide variety of types; based on shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] Research revealed that existing spring assembly aids often require users to manually pull continuously to lock the spring in a designated position, thus assembling the spring. However, this method not only consumes a lot of the user's arm strength, but also makes it inconvenient to adjust the angle of the spring while continuously pulling.

[0004] Therefore, those skilled in the art have provided spring assembly aids to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a spring assembly auxiliary device. This device has a simple structure and is easy to use. It greatly reduces the force that the user has to manually pull outwards continuously and can maintain the state of the spring after it has been pulled, which makes it convenient for the user to install the spring and thus improves the practicality of the device.

[0006] To achieve the above objectives, this utility model provides a spring assembly auxiliary device, including a pull rod, a limiting sleeve, and a pull hook. The limiting sleeve is threaded onto the pull rod, and the pull hook is rotatably disposed inside the pull rod near its lower end. Abutment blocks are fixedly disposed on both sides of the limiting sleeve near its lower end.

[0007] The above technical solution allows the pull rod and limiting sleeve to maintain stability after the spring is pulled during installation, reducing the need for continuous force from the user. The pull hook catches the spring and locks it in the anti-detachment ball. Then, the user holds the limiting sleeve and rotates the handle, causing the pull rod to move upward due to the threaded cavity. This creates a pulling force on the spring. The abutment can then be attached to an external fixing object, and the handle can be continuously rotated to pull the spring until it reaches the installation position, thus improving the practicality of the device.

[0008] Furthermore, the limiting sleeve has a threaded cavity inside;

[0009] The above technical solution, with a threaded cavity inside the limiting sleeve, allows the pull rod to move smoothly up and down when rotating.

[0010] Furthermore, a rotating block is fixedly provided at the upper end of the hook, and a rotating groove is provided inside the pull rod near its lower end, and the rotating block rotates inside the rotating groove;

[0011] By using the above technical solution, the rotating block can rotate inside the rotating groove, so that the pull rod can move without being hindered by the pull hook and the spring hook, thereby achieving the stretching of the spring.

[0012] Furthermore, an anti-slip layer is fixedly provided on the outer wall of the limiting sleeve;

[0013] The above technical solution uses an anti-slip layer fixedly installed on the outer wall of the limiting sleeve to prevent the user from slipping when holding it.

[0014] Furthermore, a handle is fixedly provided at the upper end of the pull rod;

[0015] The above technical solution uses a handle fixedly installed at the upper end of the pull rod to facilitate quick movement of the pull rod by the user, thereby stretching the spring.

[0016] Furthermore, the inner wall of the hook is fixedly provided with multiple anti-detachment balls at equal intervals;

[0017] The above technical solution uses multiple anti-detachment balls that are equidistantly fixed to the inner wall of the hook to prevent the spring from detaching from the hook when it is stretched.

[0018] This utility model has the following beneficial effects:

[0019] The spring assembly auxiliary device proposed in this utility model can maintain the stability of the hook after pulling during the installation of the spring by means of a pull rod and a limiting sleeve, reducing the need for continuous force from the user. The hook hooks the spring and locks it in the anti-disengagement ball. Then, the user holds the limiting sleeve and rotates the handle, causing the pull rod to move upward under the action of the threaded cavity, thereby creating a pulling force on the spring. The abutment can then be attached to an external fixing object, and the handle can be continuously rotated to keep the spring pulled until it reaches the installation position, thus improving the practicality of the device.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1-5 This utility model provides a specific embodiment: a spring assembly auxiliary device, including a pull rod 1, a limiting sleeve 2, and a hook 3. The limiting sleeve 2 is threaded onto the pull rod 1, and the hook 3 is rotatably disposed inside the pull rod 1 near its lower end. Abutment blocks 7 are fixedly disposed on both sides of the limiting sleeve 2 near its lower end. Through the pull rod 1 and the limiting sleeve 2, the hook 3 can maintain stability after pulling during the spring installation process, reducing the user's continuous force operation. The hook 3 hooks the spring and locks it in the anti-disengagement ball 5. Then, the user holds the limiting sleeve 2 and rotates the handle 6, causing the pull rod 1 to move upward under the action of the threaded cavity 9, thereby causing the hook 3 to exert a pulling force on the spring. Then, the abutment blocks 7 can be attached to an external fixed object. Then, the handle 6 can be continuously rotated to continuously pull the spring until it reaches the installation position, thereby improving the practicality of the device.

[0029] The limiting sleeve 2 has a threaded cavity 9 inside, which allows the pull rod 1 to move up and down smoothly when rotating. The upper end of the hook 3 is fixedly provided with a rotating block 4, and the lower end of the pull rod 1 has a rotating groove 10. The rotating block 4 rotates inside the rotating groove 10, which allows the pull rod 1 to move without being obstructed by the hook 3 and the spring hook, thus achieving the stretching of the spring. The outer wall of the limiting sleeve 2 is fixedly provided with an anti-slip layer 8 to prevent the user from slipping when holding it. The upper end of the pull rod 1 is fixedly provided with a handle 6, which allows the user to quickly move the pull rod 1 to stretch the spring. The inner wall of the hook 3 is fixedly provided with multiple anti-detachment balls 5 at equal intervals to prevent the spring from detaching from the hook 3 when stretched.

[0030] Working principle: When using this spring assembly auxiliary device, first hook the pull hook 3 onto the spring and lock the spring into the anti-detachment ball 5. Then, hold the limiting sleeve 2 and rotate the handle 6, so that the pull rod 1 moves upward under the action of the threaded cavity 9, thereby making the pull hook 3 exert a pulling force on the spring. Then, the stop block 7 can be attached to the external fixed object. Then, the handle 6 can be rotated continuously to keep the spring being pulled. At the same time, the user can free up their hand to adjust the angle of the spring until it is in the installation position, thereby reducing the user's continuous force operation and providing convenience for the user to install the spring, thus improving the practicality of the device.

[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 specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
