Description

Technical Field

[0001] This utility model relates to the field of small springs with hooks, and particularly to a small spring with a hook. 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; according to shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] In existing technology, springs provide elastic support. However, when springs are used to connect two objects, a hook structure is added to achieve the function of hanging and fixing. However, traditional springs are either ordinary springs without hooks or springs with hooks. Different environments and different scenarios require different spring structures. Therefore, springs with hooks are inconvenient to disassemble, or springs without hooks cannot be installed, resulting in limitations in use. Furthermore, mass production of both types of springs would lead to waste of resources and would not allow for portable adjustments as needed. Utility Model Content

[0004] The purpose of this utility model is to provide a small spring with a hook, which solves the problem that springs with hooks are inconvenient to disassemble or springs without hooks cannot be installed due to the need for different spring structures in different environments and scenarios, thus limiting their use.

[0005] To achieve the above objectives, a small spring with a hook is provided, comprising: a spring body, both ends of which are fixedly connected to a connecting rod, one end of the connecting rod being provided with a hook, a sleeve being sleeved between the hook and the connecting rod, a second through hole being provided on both sides of the middle portion of the sleeve, a first through hole being provided at the end of the hook near the connecting rod, a third through hole being provided at the end of the connecting rod near the hook, a pin penetrating between the second and first through holes and between the second and third through holes, a pin rod penetrating at one end of each of the two pin rods, and an external thread being provided at the bottom end of the pin rod, and the external thread being threadedly connected to the bottom end of the pin rod.

[0006] According to the small spring with a hook, an extension rod is fixedly connected to the end of the hook away from the sleeve.

[0007] According to the small spring with a hook, a pivot is fixedly connected to the outer side of the bottom end of the extension rod.

[0008] According to the small spring with a hook, a rotating plate is rotatably connected to the outer side of the rotating shaft.

[0009] According to the small spring with a hook, one end of the rotating plate is engaged with a pin.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] 1. This utility model is provided with a connecting rod, a hook, a sleeve, and a pin. The sleeve is fitted between one end of the connecting rod and the hook. Then, the pin is inserted through the first through hole, the second through hole, and the third through hole to complete the installation. This structure allows the hook of the spring to be installed and removed, which is convenient for selection and installation according to different usage conditions, and improves the portability of use.

[0012] 2. This utility model is equipped with a rotating plate, a pin post, and a pin rod. The object to be stretched is hooked on by a hook. After hooking, the rotation of the rotating plate causes it to engage with one end of the pin post. Finally, the pin rod passes through the pin post and engages with the bottom pin post through external thread, thus achieving threaded installation and fastening.

[0013] 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. Attached Figure Description
