Description

Technical Field

[0001] The utility model relates to the technical field of high-performance springs, in particular to a high-rigidity stable energy storage spring. Background Art

[0002] Energy storage springs are mechanical components that store energy in advance and can quickly release this stored energy when needed. Energy storage springs are usually made of spring steel with high elasticity and high fatigue strength. They are widely used, including operating mechanisms in circuit breakers, energy storage mechanisms in mechanical watches, and starting mechanisms of large equipment such as diesel generators.

[0003] When the existing energy storage spring is used directly, the spring is squeezed by force and the various bending parts contact each other, which easily causes the position to shift, causing the energy storage spring to be easily bent and damaged. The existing ones generally use a protruding clamping block to squeeze and abut to enhance its stability. However, after long-term use, the wear caused also makes the clamping effect of the protrusion worse and worse, the use stability of the energy storage spring is reduced, and the elastic effect of the spring is also reduced. At the same time, the mutually clamped and running-in positions also cause excessive temperature due to the action of friction, which continuously reduces the durability of the energy storage spring and reduces the use effect.

[0004] To this end, we propose a high-stiffness stable energy storage spring to solve the above problems. Utility Model Content

[0021] 1. In the utility model, two sets of limiting thin sliding rods, an extrusion plate, a protective sliding pad and a compression elastic sleeve are provided.

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0030] A high-rigidity stable energy storage spring provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] Example 1:

[0032] Combine Figure 1-Figure 3 As shown, the utility model provides a high-rigidity stable energy storage spring,

[0033] Specifically, it includes a spring body 1, two groups of extrusion plates 2 are symmetrically provided at the upper two ends of the spring body 1, two groups of limiting fine sliding rods 5 are symmetrically penetrated on the left and right sides of the abutment of the spring body 1 and the extrusion plate 2, and protective sliding pads 7 are embedded and installed on the outside of the two groups of limiting fine sliding rods 5 on both sides of the spring body 1. The outsides of the two groups of limiting fine sliding rods 5 are located between the multi-layer gaps of the spring body 1 and are sleeved with compression elastic sleeves 8. Two groups of compression holes 9 are symmetrically opened on both sides of the compression elastic sleeve 8. Embedded card sleeves 6 are embedded and installed on the inside of the two sides of the extrusion plate 2 near the outsides of the two groups of limiting fine sliding rods 5. The sleeve 6 is mainly used to protect the sliding of the extrusion plate 2 and improve the wear resistance. The upper and lower ends of the two sets of limiting fine sliding rods 5 are threaded, and are threadedly connected with a threaded limiting sleeve block 4. The threaded limiting sleeve block 4 is mainly used to limit the movement of the extrusion plate, and is also convenient for disassembly and installation. The use of the above-mentioned components, especially the spring body 1, due to the external extrusion of the extrusion plate 2, the limited deviation of the limiting fine sliding rod 5 causes the internal protective sliding pad 7 to extrude the compression elastic sleeve 8, and its elastic effect plays a supporting role, while improving the stability of the spring extension and contraction, improving the overall elastic effect.

[0034] Example 2:

[0035] Combine Figure 3 As shown, based on the first embodiment,

[0036] Specifically, heat-conducting blocks 10 are embedded and installed on the upper and lower ends of the compression elastic sleeve 8 near the protective sliding pad 7, and the outer ends of the heat-conducting blocks 10 are in contact with the end faces of the protective sliding pad 7. By using the above-mentioned components and the components in Example 1, the heat-conducting blocks 10 introduce the heat generated by the friction between the protective sliding pad 7 and the limiting thin sliding rod 5 into the compression elastic sleeve 8, and the compression elastic sleeve 8 is forced to contract and stretch, and the compression hole 9 is used to continuously exchange heat and cool down, thereby reducing damage to the spring and improving durability.

[0037] Combine Figure 1 and Figure 2 As shown, in the above embodiment,

[0038] Specifically, the outer ends of the two groups of extrusion plates 2 are connected with connecting mounting parts 3, and the connecting mounting parts 3 are mainly used to facilitate connection with external devices and facilitate the installation and use of the energy storage spring as a whole.

[0039] The working principle and use process of the utility model are as follows: first, when in use, the first connection mounting part 3 is used to install and fix it with the external device, and the extrusion plate 2 and the spring body 1 are connected in series through two sets of limiting fine sliding rods 5. The threaded limiting sleeve 4 blocks the spring body 1. Due to the external extrusion of the extrusion plate 2, the multi-section surface of the spring body 1 is forced to shrink and tighten. When it is close, the limiting deviation of the limiting fine sliding rod 5 causes the internal protective sliding pad 7 to squeeze the compression elastic sleeve 8, and the elastic effect of the compression elastic sleeve 8 plays a supporting role. It not only improves the stability of the spring's expansion and contraction, but also improves the overall elastic effect. Secondly, during use, due to the abutment of the heat-conducting blocks 10 at both ends of the compression elastic sleeve 8 with the protective sliding pad 7, the heat generated by the protective sliding pad 7 when it abuts and rubs with the limiting thin slide rod 5 is conducted to the compression elastic sleeve 8 through the heat-conducting blocks 10. The compression elastic sleeve 8 is continuously contracted and extended due to the operation of the above-mentioned components, and is continuously ventilated and heat-exchanged through the compression hole 9 to cool down, thereby reducing damage to the entire spring, improving durability, and improving the use effect.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
