Description

Technical Field

[0001] The invention relates to the technical field related to shock absorption, and specifically provides a spring support hanger with adjustable strength. Background Art

[0002] Spring bracket is a device used to support spring shock absorption system, fix and disperse pressure. It is usually used to protect buildings and equipment from vibration and noise. Spring bracket has many different types and specifications, which can be selected according to different application scenarios and requirements;

[0003] The main function of the spring bracket is to absorb and disperse the impact force, reduce vibration and noise, and improve the stability and service life of the equipment. It can adapt to different loads and environmental conditions through the expansion and deformation of the spring, so as to better play its role of shock absorption and fixing.

[0004] In addition, spring brackets can also be used to fix and support various equipment, such as pipelines, bridges, cars and airplanes. When installing spring brackets, it is necessary to ensure that their position and force conditions are correct to ensure that they can function properly.

[0005] The service life of a spring depends on pressure. The spring repeatedly performs elastic buffering during the shock absorption process. After a long time, the spring is prone to elastic fatigue problems. In addition, when the spring is under too much pressure, the spring may break and deform. For this reason, we need to make improvements. Summary of the invention

When the shock-absorbing spring is overloaded and cracks and breaks occur, the splashing of the shock-absorbing spring can be reduced. The shock-absorbing spring is mounted on the outside of the rod body and the inner rod. When the threaded plate is driven to rotate and move downward, the spring can be squeezed to adjust the current strength of the spring.

[0018] The positioning seats and locking pieces at the lower ends of the two arc-shaped covers can fix the two arc-shaped covers, thereby facilitating the later disassembly and assembly of the shock-absorbing springs. Thus, when the shock-absorbing effect of the shock-absorbing springs deteriorates, they can be quickly replaced to ensure the shock-absorbing effect.

[0019] By arranging a liquid spray pipe inside one end of the pressure box, lubricating liquid can be sprayed when used in conjunction with the later shock-absorbing spring. When the threaded plate is rotated, multiple brush rods and soft-bristle brushes can be driven to apply the coating to the outer surface of the shock-absorbing spring, thereby lubricating the shock-absorbing spring and ensuring the shock-absorbing effect.

A worker can rotate the threaded plate 17 to move the threaded surface 14 on the outer side of the rod body 13 The threaded plate 17 is movable, a locking piece is provided on the upper surface of the threaded plate 17, and a smearing piece is provided on the upper surface of the threaded plate 17 along the circumferential direction and near the edge. A shock-absorbing spring 3 is provided on the lower surface of the threaded plate 17, and the shock-absorbing spring 3 is jointly sleeved on the outside of the rod body 13 and the inner rod 20. The outer sides of the inclined rods 9 are connected to the bottom rods 5 through connecting components. Sliding pieces are provided at the upper and lower ends of the inner sides of the two bottom rods 5, and a pressure box 11 is provided at the ends of the sliding pieces.

[0032] The connecting assembly includes a reinforcing rod 2 fixedly mounted on the outside of the diagonal rod 9 , the lower end of the reinforcing rod 2 is slidably embedded in the inner side of the bottom rod 5 , and the sliding insertion of the reinforcing rod 2 and the bottom rod 5 is used in conjunction with the shock-absorbing spring 3 .

[0033] The locking member includes support rods 37 respectively fixedly mounted on both sides of the upper surface of the threaded plate 17. A connecting plate 16 is commonly mounted on the upper ends of the two support rods 37. The connecting plate 16 is movably arranged outside the rod body 13. The connection between the connecting plate 16 and the support rods 37 can facilitate the rotation of the threaded plate 17.

The slide rod 6 will drive the pressure box 11 to move to the rear end when it is impacted, so as to prompt the arc cover 4, the pressure box 11, and the slide cylinder 25 to flexibly move to one side, squeeze the buffer spring 24, and under the elastic pressure of the buffer spring 24, slow down the splashing of fragments of the shock-absorbing spring 3.

[0036] A liquid spray pipe 38 is installed on the upper part of one side of the pressure box 11, and a control valve 39 is installed inside the pressure box 11.

When a worker rotates the ring sleeve 32, the pressure block 35 can be urged to press the sealing cover 33 on one side to prevent it from leaking.

[0038] The abutting assembly includes an arc-shaped cover 4 fixedly mounted on the side of the abutting box 11 away from the slide rod 6, a positioning seat 21 is fixedly mounted on the lower end of the arc-shaped cover 4, a card hole 19 is opened on the inner side of the positioning seat 21, an extension rod 22 is extended from one side of the lower end of the abutting box 11, a locking member is arranged on the outer side of the extension rod 22, and the locking member includes a connecting plate 12 movably inserted into the outside of the extension rod 22, a magnetic pin rod 26 is fixedly mounted on the outer side of the connecting plate 12, and the two magnetic pin rods 26 are arranged as positive and negative poles. When the magnetic pin rod 26 is inserted into the card hole 19, the two magnetic pin rods 26 are abutted against each other, thereby enhancing the connectivity of the arc-shaped cover 4 and the positioning seat A shell 30 is fixedly connected to the lower outer side of 21, a block 28 is slidably installed on the inner side of the shell 30, a screw 29 is rotatably installed on the lower end surface of the block 28, and the lower end of the screw 29 passes through the lower outer side of the shell 30, one end of the magnetic pin 26 is movably inserted into the inner side of the card hole 19, and a card slot 27 for fitting the card block 28 is provided at the lower outer side of the magnetic pin 26. The connecting plate 12 is inserted into one end of the extension rod 22, the magnetic pin 26 can be inserted into the card hole 19, and then the screw 29 is rotated to make the block 28 move up and press against the card slot 27 of the magnetic pin 26, so as to self-lock the magnetic pin 26.

[0039] Working principle: When in use, under the connection of the connecting assembly and the inclined rod 9, the rod body 13 is suspended under the pad 1, and the sliding member and the buffer spring 24 can be used to enable the pressure box 11 to be set outside the shock-absorbing spring 3. The two arc-shaped covers 4 are mutually abutted and spliced ​​into a circular cover body to encircle the shock-absorbing spring 3. When the shock-absorbing spring 3 is overloaded, cracks and breakages may occur, which can reduce the splashing of fragments of the shock-absorbing spring 3. A movable plug-in connecting plate 12 is provided at the lower end of the pressure box 11, which can prompt the magnetic pin rod 26 on the outside of the connecting plate 12 to be inserted into the card hole 19 on the inner side of the positioning seat 21 at the lower end of the corresponding arc-shaped cover 4, and then the screw rod 29 is manually rotated so that the card block 28 is correspondingly carded into the card slot 27 of the magnetic pin rod 26, thereby two self-contained positive and negative poles are obtained. The magnetic pin rods 26 attract each other, causing the lower ends of the two arc-shaped covers 4 to be connected more tightly, in order to facilitate the rapid disassembly and assembly of the shock-absorbing spring 3 after it is damaged in the later stage. During daily use of the shock-absorbing spring 3, the worker drives the connecting plate 16 to rotate from the top, which can cause the threaded plate 17 at the lower end to rotate and move downward. At this time, the control valve 39 inside the pressure box 11 is started, and the corresponding spray pipe 38 can spray the lubricating liquid inside the pressure box 11 to the outer surface of the shock-absorbing spring 3. When the threaded plate 17 rotates, the corresponding brush rod 36 is driven to rotate, causing the soft brush below the outer side of the brush rod 36 to smear the outer surface of the shock-absorbing spring 3. As a result, the threaded plate 17 can not only squeeze the shock-absorbing spring 3 and adjust the current strength of the shock-absorbing spring 3, but also cooperate in lubricating and maintaining the shock-absorbing spring 3.
