[0002] A sealing ring is a device used to prevent gas or liquid leakage, usually used at the interface of machinery and equipment. Sealing rings can be divided into many types, among which the more common ones are rubber sealing rings and metal sealing rings; rubber sealing rings are usually round and made of rubber materials. They have good elasticity and can effectively prevent gas or liquid leakage. The size and shape of rubber sealing rings can be customized according to different needs, and the price is relatively cheap, so they are widely used in various equipment and machinery; metal sealing rings are usually made of metal materials and have good strength and durability. Metal sealing rings can be divided into two types: soft metal sealing rings and hard metal sealing rings. Soft metal sealing rings have better elasticity, while hard metal sealing rings are more solid;

[0003] Existing, for example, the patent publication number CN218207774U discloses a spring energy storage seal ring with good pressure resistance, including a seal ring body, a through hole is arranged inside the seal ring body, a mounting groove is arranged on the seal ring body, an elastic support component is arranged inside the mounting groove, a compression spring is fixedly installed inside the elastic support component, a protective layer is arranged on the outer wall of the seal ring body, a cooling layer is arranged on one side of the protective layer, an anti-extrusion layer is arranged on one side of the cooling layer, a reinforcing layer is arranged on one side of the anti-extrusion layer, a high temperature resistant layer is arranged on one side of the reinforcing layer, an elastic reinforcing rib is fixedly installed inside the anti-extrusion layer, and the elastic reinforcing rib is fixedly installed inside the elastic reinforcing rib. A support spring is arranged inside the rib, and a movable support column is fixedly installed at one end of the support spring; in this patent, the compressive strength of the sealing ring itself is increased and the wear of the sealing ring is compensated by the cooperation of the support spring, the compression spring and the movable support column. However, this patent does not provide a locking device for locking the support spring and the compression spring, which will make the sealing ring body inconvenient to install. Although the support spring and the two movable support columns cooperate to supplement the force on both sides of the inside of the sealing ring, when the sealing ring is worn during use, the tightening force on the worn part is poor, which will affect the sealing performance of the sealing ring itself to a certain extent.

[0004] Therefore, it is necessary to design a spring energy storage seal ring that integrates a locking device and a wear function. Utility Model Content

Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] refer to Figure 1-5A spring energy storage seal ring comprises a seal ring body 1, a mounting hole 11 is provided on the seal ring body 1, a mounting groove 12 is provided on the seal ring body 1, a plurality of spring 223 support components 2 are arranged in the mounting groove 12, the mounting groove 12 separates one side of the seal ring body 1 and forms an outer ring body 13 and an inner ring body 14, the spring 223 support component 2 comprises an annular body 21 connected to the inner wall of the outer ring body 13, a plurality of elastic members 22 connected to the annular body 21, and a pressing part 23 arranged at the end of the elastic member 22 and connected to the outer wall of the inner ring body 14, a locking member 24 for fixing the position of the pressing part 23 is provided on the elastic member 22, the elastic member 22 comprises a column 221 connected to the inner wall of the annular body 21, a groove 222 provided on the column 221 and used for installing the spring 223, and a movable body 224 connected to one end of the spring 223;

[0025] The installation hole 11 can be used to install the sealing ring body 1 on the specified equipment, so that the sealing ring body 1 can seal the equipment; wherein, the annular body 21 can play a role in supporting the outer ring body 13, so that the outer ring body 13 is not easy to deform during use, and the strength of the outer ring body 13 itself can be increased to a certain extent;

[0026] The setting of the elastic member 22 can release the remaining force when the inner wall of the inner ring body 14 is worn during use, and give the movable body 224 a driving force, and the movable body 224 will transmit the driving force to the pressing part 23, and the pressing part 23 will give the driving force to the outer wall of the inner ring body 14, so that the inner ring body 14 moves inward and fills the worn part, thereby ensuring the sealing performance of the sealing ring itself and increasing the service life of the sealing ring to a certain extent.

[0027] Preferably, reference Figure 4 and Figure 5 The locking member 24 includes two first positioning holes 241 opened on the column 221, a second positioning hole 242 penetrating the movable body 224, and a locking rod 243 passing through the first positioning hole 241 and the second positioning hole 242 and used to fix the movable body 224;

[0028] The setting of the locking piece 24 can facilitate the staff to install the sealing ring body 1. Specifically, when the staff needs to install the sealing ring body, the staff takes the locking rod 243 and inserts the locking rod 243 into the first positioning hole 241 and the second positioning hole 242, and realizes the positioning of the spring 223 body and the tightening portion 23. Among them, when the locking rod 243 completes the fixation of the spring 223 body against the tightening portion 23, the spring 223 itself will be in a compressed state and an energy storage state. After the locking piece 24 is installed, the staff will install the sealing ring body 1 at the designated equipment. At this time, the mounting hole 11 will be aligned with the equipment. The outer surface of the equipment is fitted, and then the staff removes the locking rod 243. After the locking rod 243 is removed, the energy-stored spring 223 will initially release the force, so that the pressing block presses against the outer wall of the inner ring body 14, thereby increasing the sealing performance of the inner ring body 14; and when the sealing ring body 1 has been used for a period of time, the inner wall of the sealing ring body 1 and the inner wall of the inner ring body 14 will be worn, thereby reducing the thickness of the inner ring body 14 itself. When this happens, the spring 223 will further release the force, and make the inner wall of the inner ring body 14 fit with the outer surface of the equipment again, thereby increasing the service life of the sealing ring to a certain extent.

[0029] Preferably, reference Figure 5 The upper first positioning hole 241 passes through the column 221 and is connected to the groove body 222. The upper positioning hole passes through the column 221 and the lower first positioning hole 241 passes through the column 221. It can provide a basis for the insertion and fixing of the locking rod 243, thereby ensuring the installation of the sealing ring.

[0030] Preferably, reference Figure 4 The locking rod 243 is arranged in a T shape. The T-shaped locking rod 243 can be convenient for the staff to use and remove the locking rod 243; of course, for those skilled in the art, the locking rod 243 can also adopt other design methods, and these design methods are also within the protection scope of this application document.

[0031] Preferably, reference Figure 3 and Figure 4 The clamping portion 23 is arranged in an arc shape, and the advantage of the arc-shaped clamping portion 23 is that fewer springs 223 can be used to support the assembly 2 to complete the clamping work on the outer wall of the inner ring body 14. Of course, for those skilled in the art, the clamping portion 23 can also be circular, conical, etc., and these designs are also within the protection scope of this application document.

[0032] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
