Description

Technical Field

[0001] The invention relates to the technical field of air compressor shock absorption, and in particular to an air compressor shock absorption bracket and a use method thereof. Background Art

[0002] An air compressor is a device that compresses air and is commonly used in a variety of fields such as industry, machinery manufacturing, construction, and home. It can compress air and store it in an air tank for later use. Air compressors can be divided into many types according to different types, such as screw type, piston type, centrifugal type, etc. Existing air compressors often produce continuous vibrations during operation, which will continuously produce low-frequency noise, affecting the physical and mental health of patients and staff. And this vibration often leads to the vibration of the internal structure of the air compressor itself, constantly wearing out the parts inside the air compressor, and thus affecting its service life. The conventional shock-absorbing structure directly reduces shock by setting a spring at the bottom of the compressor, and a single shock-absorbing structure cannot cope with the vibrations generated in all directions during the operation of the compressor, and cannot effectively eliminate the vibrations, thereby ensuring the stability of the compressor operation. Summary of the invention

[0003] Technical purpose: In view of the shortcomings of existing air compressor shock absorption, the present invention discloses an air compressor shock absorption bracket and a use method.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution: A shock-absorbing bracket for an air compressor comprises a shock-absorbing bracket lower layer arranged at the bottom for providing overall supporting force for the air compressor and the bracket, and a shock-absorbing bracket upper layer movably arranged above the shock-absorbing bracket lower layer, the air compressor is fixed on the shock-absorbing bracket upper layer, a longitudinal shock-absorbing mechanism and a transverse shock-absorbing mechanism are provided between the shock-absorbing bracket lower layer and the shock-absorbing bracket upper layer, the transverse shock-absorbing mechanism is provided with a shock-absorbing fixing piece which moves synchronously with the shock-absorbing bracket upper layer during longitudinal vibration, a connecting rod assembly for converting longitudinal movement into transverse movement is provided below the shock-absorbing fixing piece, an elastic assembly is provided at the transverse moving end of the connecting rod assembly, the movement of the connecting rod assembly is elastically limited by the elastic assembly, and when the air compressor generates longitudinal vibration, the longitudinal shock-absorbing mechanism is assisted by the connecting rod assembly and the elastic assembly to perform shock reduction.

[0005] Preferably, the elastic component of the present invention includes a buffer fixing groove fixed on the lower layer of the shock absorbing bracket, in which a transverse guide rod is arranged along the moving direction of the corresponding transverse moving end of the connecting rod assembly, the end of the connecting rod assembly is slidingly connected to the transverse guide rod, and a transverse shock absorbing spring is arranged on the transverse guide rod, and the end of the transverse shock absorbing spring is connected to the transverse moving end of the connecting rod assembly to provide a transverse force to the connecting rod assembly.

[0006] Preferably, the connecting rod assembly of the present invention includes a connecting rod and a slip ring, the slip ring is sleeved on the transverse guide rod and fixedly connected to the end of the transverse shock-absorbing spring, one end of the connecting rod is hinged to the slip ring, and the other end is hinged to the shock-absorbing fixing piece.

[0007] Preferably, a limit block is provided at the end of the transverse guide rod of the present invention near the side where the slip ring is located, and the limit block prevents the slip ring from detaching from the transverse guide rod. A shock-absorbing pad is provided in the area below the limit block and between the lower layer of the shock-absorbing bracket.

[0008] Preferably, an elastic buffer assembly is provided on the transverse guide rod of the present invention at the end of the transverse shock-absorbing spring facing away from the connecting rod assembly, and the elastic buffer assembly includes a second slip ring and a buffer spring provided between the second slip ring and the inner wall of the buffer fixing groove, so that the transverse movement caused by the connecting rod assembly is subjected to secondary buffering and shock absorption by the buffer spring and the second slip ring.

[0009] Preferably, a sliding rod is provided on the second sliding ring of the present invention, and the sliding of the second sliding ring is guided and positioned by the cooperation between the sliding rod and the sliding groove provided on the inner wall of the buffer fixing groove.

[0010] Preferably, the shock-absorbing fixture of the present invention is arranged in a region corresponding to the center of the air compressor, and the number of connecting rod assemblies and elastic assemblies is 4 groups, which are evenly arranged at 90° intervals along the circumference of the shock-absorbing fixture.

[0011] Preferably, the longitudinal shock absorbing mechanism of the present invention is arranged on the upper layer of the shock absorbing bracket and corresponds to the four corners of the air compressor. The longitudinal shock absorbing mechanism includes a longitudinal shock absorbing spring and a longitudinal guide rod passing through the longitudinal shock absorbing spring.

[0012] The present invention discloses a method for using the shock-absorbing bracket of the air compressor. The shock-absorbing bracket is arranged below the air compressor. When the air compressor generates lateral vibration during operation, an elastic component of the lateral shock-absorbing mechanism in the corresponding direction generates a force opposite to the vibration direction, thereby reducing the amplitude of the lateral vibration. When the air compressor generates longitudinal vibration during operation, the longitudinal shock-absorbing mechanism buffers the longitudinal vibration. During the longitudinal vibration, the distance between the upper layer of the shock-absorbing bracket and the lower layer of the shock-absorbing bracket changes. The shock-absorbing fixing piece moves up and down synchronously with the upper layer of the shock-absorbing bracket, driving the connecting rod assembly connected to the shock-absorbing fixing piece to move, causing the lateral moving end of the connecting rod assembly to generate lateral displacement. The elastic component connected to the connecting rod assembly limits the lateral displacement, thereby realizing longitudinal shock absorption assisted by the lateral shock-absorbing mechanism during the longitudinal vibration.

[0014] Beneficial effects: The air compressor shock absorbing bracket and the use method disclosed in the present invention have the following beneficial effects: 1. The lateral shock absorbing mechanism and the longitudinal shock absorbing mechanism provided in the present invention can simultaneously meet the shock absorbing requirements in different directions when the air compressor is running. In addition, for the longitudinal vibration with a large vibration amplitude, the vibration in the central area of ​​the air compressor is transmitted to the lateral shock absorbing mechanism through the provided connecting rod assembly and elastic assembly, thereby offsetting the longitudinal stress generated during the vibration, assisting in the longitudinal shock absorption, and improving the shock absorption capacity of the bracket.

[0015] 2. The present invention utilizes the connecting rod assembly to disperse the longitudinal stress, which can reduce the pressure of the longitudinal shock absorbing mechanism, thereby reducing the loss and extending the service life of the shock absorbing bracket.

[0016] 3. The present invention arranges an elastic buffer component to perform secondary buffering on the lateral shock-absorbing spring. Compared with the structure of a single spring, it can effectively reduce the loss of the shock-absorbing spring and increase the upper limit of the shock absorption of the shock-absorbing bracket.

DETAILED DESCRIPTION

[0019] Reference will now be made in detail to embodiments of the present disclosure, one or more examples of which are set forth herein below. Each embodiment and example is provided by way of explanation of the apparatus, composition and materials of the present disclosure, rather than limitation. On the contrary, the following description provides a convenient illustration of an exemplary embodiment for implementing the present disclosure. In fact, it will be clear to those skilled in the art that various modifications and variations may be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0020] like Figure 1-Figure 3As shown, the present invention discloses an air compressor shock-absorbing bracket, comprising a shock-absorbing bracket lower layer 2 arranged at the bottom for providing overall supporting force for the air compressor 1 and the bracket, and a shock-absorbing bracket upper layer 3 movably arranged above the shock-absorbing bracket lower layer 2, the air compressor 1 is fixed on the shock-absorbing bracket upper layer 3, a longitudinal shock-absorbing mechanism and a transverse shock-absorbing mechanism are provided between the shock-absorbing bracket lower layer 2 and the shock-absorbing bracket upper layer 3, the transverse shock-absorbing mechanism is provided with a shock-absorbing fixing member 4 which moves synchronously with the shock-absorbing bracket upper layer 3 during longitudinal vibration, a connecting rod assembly 5 for converting longitudinal movement into transverse movement is arranged below the shock-absorbing fixing member 4, an elastic component 6 is arranged at the transverse moving end of the connecting rod assembly 5, the movement of the connecting rod assembly 5 is elastically limited by the elastic component 6, and when the air compressor 1 generates longitudinal vibration, the longitudinal shock-absorbing mechanism is assisted by the connecting rod assembly 5 and the elastic component 6 to perform shock absorption.

[0021] The longitudinal shock absorbing mechanism of the present invention is arranged on the upper layer 3 of the shock absorbing bracket and corresponds to the four corners of the air compressor. The longitudinal shock absorbing mechanism includes a longitudinal shock absorbing spring 18 and a longitudinal guide rod 19 inserted into the longitudinal shock absorbing spring 18. The shock absorbing function of the longitudinal shock absorbing mechanism is realized by the longitudinal shock absorbing spring 18, and the deformation of the longitudinal shock absorbing spring 18 is limited by the longitudinal guide rod 19.

[0022] During lateral vibration, the elastic component 6 provides lateral vibration damping, and effectively eliminates lateral vibrations in all directions to ensure the stable operation of the air compressor. Figure 2 As shown, in an embodiment of the present invention, the shock-absorbing fixing member 4 is preferably arranged in an area corresponding to the center of the air compressor 1, and the number of the connecting rod assemblies 5 and the elastic assemblies 6 are both 4 groups, which are evenly arranged at 90° intervals along the circumference of the shock-absorbing fixing member 4; the lateral shock-absorbing effect is ensured; and during longitudinal vibration, the longitudinal vibration is dispersed by the connecting rod assembly, and the elastic assemblies in all directions are used for buffering and shock absorption. Compared with the shock-absorbing method of using only the longitudinal shock-absorbing mechanism, the shock-absorbing bracket of the present invention can further increase the upper limit of shock absorption and reduce the damage to the longitudinal shock-absorbing mechanism during vibration, thereby extending the service life of the shock-absorbing bracket.

[0023] In a specific embodiment, the elastic component 6 of the present invention includes a buffer fixing groove 7 fixed on the lower layer 2 of the shock absorbing bracket, and the bottom of the buffer fixing groove 7 is fixed on the lower layer 2 of the shock absorbing bracket to provide lateral support force for the lateral shock absorbing mechanism. In the buffer fixing groove 7, a lateral guide rod 8 is arranged along the moving direction of the lateral moving end of the corresponding connecting rod assembly 5, and the end of the connecting rod assembly 5 is slidably connected to the lateral guide rod 8. A lateral shock absorbing spring 9 is arranged on the lateral guide rod 8, and the end of the lateral shock absorbing spring 9 is connected to the lateral moving end of the connecting rod assembly 5 to provide lateral force to the connecting rod assembly 5.

[0024] The connecting rod assembly 5 includes a connecting rod 10 and a slip ring 11. The slip ring 11 is sleeved on the transverse guide rod 8 and fixedly connected to the end of the transverse shock-absorbing spring 9. One end of the connecting rod 10 is hinged to the slip ring 11, and the other end is hinged to the shock-absorbing fixing member 4.

[0025] When lateral vibration occurs, since the length of the connecting rod 10 is fixed and there is the deadweight of the air compressor 1 on the upper layer 3 of the shock-absorbing bracket, the lower end of the connecting rod 10 will still drive the slip ring 11 to slide along the corresponding lateral guide rod 8 to reduce shock during vibration. Due to the setting of the connecting rod 10, when the lateral vibration force is transmitted, a part of the force can be converted into a longitudinal force to act on the shock-absorbing fixing part 4, and this part of the force is eliminated by using the gravity of the air compressor 1 and the longitudinal shock-absorbing mechanism to reduce the amplitude of the lateral vibration.

[0026] In order to improve the structural safety, a limit block 12 is provided at the end of the transverse guide rod 8 on the side close to the slip ring 11. The limit block 12 prevents the slip ring 11 from being detached from the transverse guide rod 8. A shock-absorbing pad 13 is provided in the area below the limit block 12 and between the lower layer 2 of the shock-absorbing bracket. The setting of the shock-absorbing pad 13 is used to ensure that when the longitudinal component of the force applied by the connecting rod 10 is received, the limit block 12 at the end of the transverse guide rod 8 can be avoided from colliding with the lower layer 2 of the shock-absorbing bracket, thereby reducing structural wear and extending the service life of the shock-absorbing bracket.

[0027] In addition, an elastic buffer assembly is arranged on the transverse guide rod 8 of the present invention at the end of the transverse shock-absorbing spring 9 away from the connecting rod assembly 5, and the elastic buffer assembly includes a second slip ring 14 and a buffer spring 15 arranged between the second slip ring 14 and the inner wall of the buffer fixing groove 7. A sliding rod 16 is arranged on the second slip ring 14, and the sliding of the second slip ring 14 is guided and positioned by the cooperation of the sliding rod 16 and the sliding groove 17 arranged on the inner wall of the buffer fixing groove 7; the transverse movement caused by the connecting rod assembly 5 is secondary buffered and damped by the buffer spring 15 and the second slip ring 14, so as to reduce the wear of the transverse shock-absorbing spring during the shock-absorbing process, and improve the shock-absorbing upper limit of the shock-absorbing bracket while ensuring the shock-absorbing capacity.

[0028] The present invention also discloses a method for using the shock-absorbing bracket of the air compressor, wherein the shock-absorbing bracket is arranged below the air compressor, and when the air compressor generates lateral vibration during operation, an elastic component of the lateral shock-absorbing mechanism in the corresponding direction generates a force opposite to the vibration direction, thereby reducing the amplitude of the lateral vibration; when the air compressor generates longitudinal vibration during operation, the longitudinal shock-absorbing mechanism buffers the longitudinal vibration, and during the longitudinal vibration, the distance between the upper layer of the shock-absorbing bracket and the lower layer of the shock-absorbing bracket changes, and the shock-absorbing fixing piece moves up and down synchronously with the upper layer of the shock-absorbing bracket, driving the connecting rod assembly connected to the shock-absorbing fixing piece to move, so that the lateral moving end of the connecting rod assembly generates lateral displacement, and the elastic component connected to the connecting rod assembly limits the lateral displacement, thereby realizing that during the longitudinal vibration, the lateral shock-absorbing mechanism assists in longitudinal shock absorption; when the lateral moving end of the connecting rod assembly is shock-absorbing and buffered by the elastic component, the vibration of the elastic component is secondary buffered by the elastic buffer component at the end of the elastic component away from the connecting rod assembly. Correspondingly, in combination with the connecting rod assembly structure of the present invention, when there is only lateral vibration, the connecting rod can also be used to disperse the lateral force, and the gravity of the air compressor and the longitudinal shock absorbing mechanism can be used to assist in eliminating the lateral vibration; the lateral shock absorbing mechanism of the present invention can cooperate with the longitudinal shock absorbing mechanism to achieve shock absorption in all directions during the operation of the air compressor, and compared with an independently arranged shock absorbing structure, it can reduce the vibration amplitude in a single direction and reduce the spring loss caused by shock absorption, thereby increasing the service life of the shock absorbing bracket. For the air compressor, which generates vibration more frequently, long-term and efficient shock absorption can be achieved to reduce losses.
