The utility model is applicable to the field of machinery.

Description

Technical Field

[0001] The utility model relates to the field of machinery, and more specifically, it relates to a structure for quickly loading and unloading compression springs. Background Art

[0002] In the mechanism of a high-voltage circuit breaker, the compression spring is an important elastic component, which is usually used to provide the force and energy storage required by the operating mechanism. In the traditional compression spring structure, when loading, unloading and maintaining, the space in the high-voltage circuit breaker is usually relatively narrow, and it may be difficult for the traditional compression spring structure to be quickly loaded and unloaded in the limited space, increasing the time and difficulty of maintenance and overhaul.

[0003] To solve these problems, a new type of compression spring loading and unloading structure is needed, which can realize the quick installation and disassembly of the compression spring in the high-voltage circuit breaker, facilitate adjustment and maintenance, and ensure the stability and reliability of the compression spring at the same time. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a structure for quickly loading and unloading compression springs with convenient installation and quick loading and unloading.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A structure for quickly loading and unloading compression springs, including a loading and unloading device and a compression spring arranged on the loading and unloading device. The loading and unloading device includes a base, a conduit is arranged on the base, and a spring compression sleeve is arranged above the conduit. The compression spring is sleeved on the periphery of the spring compression sleeve. A full-thread bolt is arranged at the top of the spring compression sleeve. When the full-thread bolt presses downward against the spring compression sleeve, the spring compression sleeve presses the compression spring downward along the conduit, so that the compression spring enters the pre-compressed state; conversely, when the full-thread bolt drives the spring compression sleeve upward, the spring compression sleeve drives the compression spring upward along the conduit, so that the compression spring rebounds.

[0006] By adopting the above technical solution, the up and down movement of the full-thread bolt can quickly drive the spring compression sleeve, thereby realizing the quick compression and rebound of the compression spring, improving the loading and unloading efficiency; the spring compression sleeve moves along the conduit, which can ensure the stable and reliable compression and rebound process of the compression spring, and reduce the situation of compression spring deviation or instability.

[0007] The utility model is further set as follows: A gasket is arranged between the full-thread bolt and the spring compression sleeve. The spring compression sleeve is provided with a through hole, and the inner diameter of the spring compression sleeve is adapted to the outer diameter of the conduit. The conduit is provided with internal threads, and the full-thread bolt is provided with external threads adapted to the internal threads. The outer diameter of the full-thread bolt is smaller than the inner diameter of the spring compression sleeve. The full-thread bolt passes through and is inserted into the spring compression sleeve through the gasket. When the full-thread bolt rotates and presses downward, the gasket abuts against the periphery of the full-thread bolt to fix the full-thread bolt.

[0008] By adopting the above technical solution, the setting of the gasket can increase the friction between the all-thread bolt and the spring bushing, enabling the all-thread bolt to be more firmly fixed on the spring bushing when rotating and pressing down, preventing loosening; the gasket can play a buffering role, reducing the direct wear between the all-thread bolt and the spring bushing, and extending the service life of the components.

[0009] The present utility model is further configured as: an extension portion is provided on the spring bushing, the outer diameter of the extension portion is greater than the outer diameter of the compression spring, the top of the compression spring abuts against the extension portion and the bottom of the compression spring abuts against the base, so that the compression spring is fixedly sleeved on the periphery of the spring bushing.

[0010] By adopting the above technical solution, the setting of the extension portion can effectively limit the position of the compression spring, enabling it to be stably sleeved on the periphery of the spring bushing, and preventing the compression spring from shifting or falling off during operation; the top of the compression spring abuts against the extension portion and the bottom abuts against the base, enabling the pressure to be evenly transmitted to the compression spring, ensuring that the compression and rebound processes of the compression spring are more stable.

[0011] The present utility model is further configured as: a groove is provided at the bottom end of the base, and the conduit is fixedly connected to the base.

[0012] By adopting the above technical solution, the conduit will not become loose or displaced, thus ensuring the stability of the entire structure.

[0013] The present utility model is further configured as: the shape and size of the groove match the installation part to ensure the fixed installation of the base.

[0014] By adopting the above technical solution, it can ensure that the base is closely fitted with the installation part, improving the installation accuracy. This matching can make the base more stable after installation, reducing the instability caused by shaking or displacement during use.

[0015] The present utility model is further configured as: the gasket is made of rubber material.

[0016] By adopting the above technical solution, the gasket plays a role of buffering and shock absorption, reducing the impact and wear between the all-thread bolt and the spring bushing, extending the service life of the components, and improving the sealing performance of the connection.

[0017] The present utility model is further configured as: the loading and unloading device is made of high-strength alloy steel.

[0018] By adopting the above technical solution, high-strength alloy steel has excellent mechanical properties, can withstand large pressures and loads, ensuring that the loading and unloading device is not easily deformed or damaged during operation. In high-voltage environments such as high-voltage circuit breakers, high-strength alloy steel can provide reliable support and protection to ensure the normal operation of the mechanism.

[0021] Refer to Figure 1 For a further description of an embodiment of a quick-loading and unloading compression spring structure of the present utility model.

[0022] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein can be interpreted accordingly.

[0023] Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0024] A quick-loading and unloading compression spring structure includes a loading and unloading device and a compression spring 1 provided on the loading and unloading device. The loading and unloading device includes a base 2, a conduit 3 is provided on the base 2, and a spring compression sleeve 4 is placed above the conduit 3. The compression spring 1 is sleeved on the periphery of the spring compression sleeve 4. A full-thread bolt 5 is provided at the top of the spring compression sleeve 4. When the full-thread bolt 5 presses downward against the spring compression sleeve 4, the spring compression sleeve 4 presses the compression spring 1 downward along the conduit 3, so that the compression spring 1 enters the pre-compressed state; conversely, when the full-thread bolt 5 drives the spring compression sleeve 4 upward, the spring compression sleeve 4 drives the compression spring 1 upward along the conduit 3, so that the compression spring 1 rebounds. The up and down movement of the full-thread bolt 5 can quickly drive the spring compression sleeve 4, thereby realizing the quick compression and rebound of the compression spring 1, improving the loading and unloading efficiency; the spring compression sleeve 4 moves along the conduit 3, which can ensure the stable and reliable compression and rebound process of the compression spring 1, reducing the situation of the compression spring 1 shifting or being unstable. Just use a tool or a power tool to directly remove the full-thread bolt to realize the spring rebound.

[0025] Preferably, a gasket 6 is provided between the full-thread bolt 5 and the spring bushing 4. A through-hole 7 is provided in the spring bushing 4, and the inner diameter of the spring bushing 4 is adapted to the outer diameter of the conduit 3. The conduit 3 is provided with an internal thread 8, and the full-thread bolt 5 is provided with an external thread 9 adapted to the internal thread 8. The outer diameter of the full-thread bolt 5 is smaller than the inner diameter of the spring bushing 4. The full-thread bolt 5 is inserted through the spring bushing 4 via the gasket 6. When the full-thread bolt 5 is rotated and pressed down, the gasket 6 abuts against the circumferential side of the full-thread bolt 5 to fix the full-thread bolt 5. The setting of the gasket 6 can increase the friction between the full-thread bolt 5 and the spring bushing 4, enabling the full-thread bolt 5 to be more firmly fixed on the spring bushing 4 when rotated and pressed down, preventing loosening; the gasket 6 can play a buffering role, reducing the direct wear between the full-thread bolt 5 and the spring bushing 4 and extending the service life of the components.

[0026] Preferably, an extension portion 10 is provided on the spring bushing 4. The outer diameter of the extension portion 10 is larger than the outer diameter of the compression spring 1. The top of the compression spring 1 abuts against the extension portion 10, and the bottom of the compression spring 1 abuts against the base 2, so that the compression spring 1 is fixedly sleeved on the circumferential side of the spring bushing 4. The setting of the extension portion 10 can effectively limit the position of the compression spring 1, enabling it to be stably sleeved on the circumferential side of the spring bushing 4 and preventing the compression spring 1 from shifting or falling off during operation; the top of the compression spring 1 abuts against the extension portion 10 and the bottom abuts against the base 2, enabling the pressure to be evenly transmitted to the compression spring 1 and ensuring a smoother compression and rebound process of the compression spring 1.

[0027] Preferably, a groove 11 is provided at the bottom end of the base 2. The conduit 3 is fixedly connected to the base 2, so that the conduit 3 will not become loose or displaced, thus ensuring the stability of the entire structure.

[0028] Preferably, the shape and size of the groove 11 match the installation part, ensuring the fixed installation of the base 2. It can ensure that the base 2 is closely attached to the installation part, improving the installation accuracy. This matching can make the base 2 more stable after installation, reducing the unstable situation caused by shaking or displacement during use.

[0029] Preferably, the gasket 6 is made of rubber material, enabling the gasket 6 to play a buffering and shock-absorbing role, reducing the impact and wear between the full-thread bolt 5 and the spring bushing 4, extending the service life of the components, and improving the sealing performance of the connection.

[0030] Preferably, the loading and unloading device is made of high-strength alloy steel. High-strength alloy steel has excellent mechanical properties and can withstand large pressures and loads, ensuring that the loading and unloading device is not easily deformed or damaged during operation. In high-voltage environments such as high-voltage circuit breakers, high-strength alloy steel can provide reliable support and protection to ensure the normal operation of the mechanism.

[0031] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model shall be included within the protection scope of the present utility model.
