Technical Field

[0001] The utility model relates to the technical field of viscous dampers, in particular to a protective viscous damper. Background Art

[0002] The viscous damper is made based on the principle that viscous resistance will be generated when the fluid passes through the throttle hole. It is a damper related to stiffness and speed.

[0003] For example, the Chinese patent authorization announcement number is CN218564259U, "discloses a viscous damper with outer layer protection, including a viscous damper body, a first earring type connector, a second earring type connector, a through hole and a bolt, characterized in that: an inner layer protective cover is arranged on the outer wall of the viscous damper body";

[0004] The above-mentioned reference document realizes multiple protections for the viscous damper through the designed inner protective cover, spring rod, shock absorbing spring, upper protective shell and lower protective shell, which not only plays an anti-collision effect, but also prevents external dust and rain from entering the interior of the viscous damper;

[0005] However, when the above-mentioned viscous damper is in use, the external protective cover of the damper is assembled by multiple sets of bolts. When disassembling, multiple sets of bolts need to be disassembled, which is inconvenient to operate. In addition, protective covers are installed on both sides of the outside of the damper, and the sealing of both ends of the protective covers cannot be guaranteed, which is easy to enter dust and rainwater. Utility Model Content

[0006] The utility model aims to provide a protective viscous damper, which can protect the damper body from collision while increasing the sealing between the protective mechanism and the damper body, and is more convenient for disassembly and assembly of the external protective mechanism.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective viscous damper, comprising a damper body, a first buffer plate, and a second buffer plate, end covers are fixedly installed at both ends of the fixed part of the damper body, the first buffer plate and the second buffer plate are symmetrically installed on both sides of the outside of the damper body, and end sealing covers are detachably installed at both ends of the first buffer plate and the second buffer plate through threads, an external shield is arranged between the two groups of the end sealing covers, and buffer components are installed at equal intervals on the outer circumference of the damper body, the buffer components include a fixed block fixedly installed on the outside of the damper body, a movable block is movably inserted inside the fixed block, and a buffer spring is arranged between the movable block and the fixed block.

[0008] Preferably, a bellows sleeve is fixedly mounted on the top of the end cover, and one end of the bellows sleeve is fixedly mounted on the outer side of the movable part of the damper body.

[0009] Preferably, a thread groove is formed on the outside of the first buffer plate, and the end sealing cover is fixedly connected to the thread grooves at the ends of the first buffer plate and the second buffer plate respectively through threads.

[0010] Preferably, the inner wall of the end sealing cover is in conflict with the side surface of the end cover on the same side.

[0011] Preferably, sealing grooves are respectively provided at the ends of the two groups of end sealing covers, and both ends of the external shield are convex structures, and both ends of the external shield are respectively inserted into the end sealing grooves of the two groups of end sealing covers.

[0012] Preferably, the first buffer plate and the second buffer plate are provided with interference grooves on their inner walls, and one end of the movable block in the buffer assembly is respectively inserted into the corresponding interference groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, the first buffer plate and the second buffer plate respectively contact the ends of the movable blocks in the external buffer assembly of the damper body through the inner contact grooves, and the two groups of buffer plates are sleeved and sealed through the external shield, so that the ends of the two groups of buffer plates are bound to the outside of the damper body by the end sealing covers connected by threads. When the external protection mechanism of the viscous damper is disassembled and assembled, it is only necessary to disassemble the threads of the end sealing covers on both sides, and the external shield and the two groups of buffer plates can be removed from the outside of the damper body step by step. Compared with the existing damper external installation protection mechanism, the external protection mechanism can be disassembled and assembled without disassembling multiple groups of bolt structures;

[0015] In the utility model, two groups of semicircular first buffer plates and second buffer plates are respectively sleeved on both sides of the outside of the damper body, and the connection between the two groups of buffer plates is sealed by an external protective cover sleeve, so that the external protective cover seals the two groups of buffer plates, and the two groups of end sealing covers are threadedly connected with the thread grooves at the ends of the two groups of buffer plates through threads, so that the end sealing covers seal the ends of the buffer plates. In this way, the protective mechanism outside the viscous damper can form a sealing protection between the damper bodies, preventing the external protective mechanism from forming a gap during installation, which is easy to enter dust and rainwater.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-5 The utility model provides a technical solution: a protective viscous damper, comprising a damper body 1, a first buffer plate 4, and a second buffer plate 41, end covers 11 are fixedly installed at both ends of the fixed part of the damper body 1, and the first buffer plate 4 and the second buffer plate 41 are symmetrically installed on both sides of the outside of the damper body 1;

[0024] The first buffer plate 4 and the second buffer plate 41 are respectively provided with end sealing covers 3 detachably installed at both ends through threads, an external shield 2 is provided between the two sets of end sealing covers 3, and buffer components 6 are installed at equal intervals on the outer circumference of the damper body 1, and the buffer components 6 include a fixed block 62 fixedly installed on the outer side of the damper body 1, a movable block 61 is movably inserted in the fixed block 62, and a buffer spring 63 is provided between the movable block 61 and the fixed block 62;

[0025] The two groups of semicircular first buffer plates 4 and second buffer plates 41 respectively contact with the buffer assembly 6 outside the damper body 1 through the inner contact groove 5, and the movable block 61 in the buffer assembly 6 and the buffer spring 63 in the fixed block 62 form a shock absorber structure, so that the buffer plate and the buffer assembly 6 play a role of buffering and protecting the outside of the damper body 1 through elastic support;

[0026] Two groups of semicircular first buffer plates 4 and second buffer plates 41 are respectively sleeved on both sides of the outside of the damper body 1, and the two groups of buffer plates are sealed and connected by the external shield 2, so that the external shield 2 seals the two groups of buffer plates, and the two groups of end sealing covers 3 are threadedly connected with the thread grooves 42 at the ends of the two groups of buffer plates through threads, so that the end sealing covers 3 seal the ends of the buffer plates, so that the external protective mechanism of the viscous damper can form a sealed protection between the damper body 1, preventing the external protective mechanism from forming a gap during installation, which is easy to enter dust and rainwater;

[0027] The first buffer plate 4 and the second buffer plate 41 respectively contact the ends of the movable block 61 in the external buffer assembly 6 of the damper body 1 through the inner contact groove 5, and the two groups of buffer plates are sealed and connected through the external protective cover 2, so that the ends of the two groups of buffer plates are threadedly connected through the end sealing covers 3 to bind the two groups of buffers and the external protective cover 2 to the outside of the damper body 1. When disassembling and assembling the external protective mechanism of the viscous damper, it is only necessary to disassemble the threads of the end sealing covers 3 on both sides to remove the external protective cover 2 and the two groups of buffer plates from the outside of the damper body 1 step by step. Compared with the existing external installation protection mechanism of the damper, the external protection mechanism can be disassembled and assembled without disassembling multiple groups of bolt structures.

[0028] Among them, a bellows sleeve 12 is fixedly installed on the top of the end cover 11, and one end of the bellows sleeve 12 is fixedly installed on the outer side of the movable part of the damper body 1. The movable end of the damper body 1 forms a seal with the end cover 11 through the bellows sleeve 12. In this way, when a protective mechanism is installed on the outside of the damper body 1, the sealing between the end cover 11 and the movable end of the damper can be guaranteed.

[0029] Among them, a threaded groove 42 is opened on the outside of the first buffer plate 4, and the end sealing cover 3 is fixedly connected with the end threaded grooves 42 of the first buffer plate 4 and the second buffer plate 41 through threads. The inner wall of the end sealing cover 3 conflicts with the side of the end cover 11 on the same side. The ends of the two groups of end sealing covers 3 are respectively opened with sealing grooves 31. The two ends of the external protective cover 2 are convex structures, and the two ends of the external protective cover 2 are respectively inserted into the end sealing grooves 31 of the two groups of end sealing covers 3. The two groups of semicircular first buffer plates 4 and second buffer plates 41 are respectively sleeved on both sides of the outside of the damper body 1. The joints of the two groups of buffer plates are sealed by the sleeve of the external protective cover 2, so that the external protective cover 2 seals between the two groups of buffer plates.

[0030] Among them, the first buffer plate 4 and the second buffer plate 41 are provided with interference grooves 5 on the inner walls, and one end of the movable block 61 in the buffer assembly 6 is respectively inserted into the corresponding interference groove 5, and the two groups of buffer plate ends and the external protective cover 2 can be restrained to the outside of the damper body 1 through the two groups of end sealing covers 3. In this way, when disassembling and assembling the external protection mechanism of the viscous damper, it is only necessary to disassemble the threads of the end sealing covers 3 on both sides, and the external protective cover 2 and the two groups of buffer plates can be removed step by step from the outside of the damper body 1.

[0031] Working principle: When installing the protection mechanism on the outside of the viscous damper body 1, firstly, two groups of semicircular first buffer plates 4 and second buffer plates 41 are respectively sleeved on the outside of the damper body 1, so that the movable blocks 61 in the buffer assembly 6 respectively contact the inner contact grooves 5 of the two groups of buffer plates;

[0032] Then, the external shield 2 is sleeved outside the two groups of buffer plates, so that the external shield 2 seals between the two groups of buffer plates;

[0033] Finally, the two groups of end sealing covers 3 are threadedly connected to the thread grooves 42 at the ends of the two groups of buffer plates through threads until the inner walls of the two groups of end sealing covers 3 collide with the side surfaces of the end covers 11 on the same side, so that the end sealing covers 3 seal the ends of the buffer plates. In this way, the external protective mechanism of the viscous damper can form a sealing protection between the damper body 1 to prevent the formation of gaps during the installation of the external protective mechanism, which is easy for dust and rainwater to enter.

The scope of the present invention is defined by the appended claims and their equivalents.
