Description

Technical Field

[0001] This utility model relates to the technical field of shock absorbers, specifically a sealed three-way metal shock absorber. Background Technology

[0002] Shock absorbers are used to suppress the oscillation and impact when the spring absorbs shock and rebounds. When the piston reciprocates in the cylinder, the oil in the shock absorber flows back and forth between two isolated inner cavities through a narrow orifice on the valve. Due to the friction between the orifice wall and the oil, as well as the internal friction of the liquid molecules, a damping force is generated, thereby converting mechanical energy into heat energy which is absorbed by the oil and the housing.

[0003] Existing shock absorbers all use rubber dust covers to prevent dust. However, when used for a long time, the rubber dust covers are easily affected by the environment, which can cause them to age or even be damaged, affecting their dust-proof effect and causing the springs to be corroded by external impurities, thus reducing the service life of the shock absorber.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] This utility model proposes a sealed three-way metal shock absorber, comprising:

[0033] Casing 1, filled with oil;

[0034] The side wall of the housing 1 has a filling port, which makes it convenient for workers to add oil into the housing 1;

[0035] Sliding plate 2 is slidably installed inside housing 1;

[0036] Through hole 3 is formed inside sliding plate 2;

[0037] The sliding plate 2 slides inside the housing 1, which allows the oil inside the housing 1 to flow through the through hole 3, and can play a damping role for the sliding plate 2;

[0038] An annular groove 4 is formed on the shell 1;

[0039] Dust cover 5, the lower end of which is inserted into the annular groove 4;

[0040] The piston rod 6 is fixedly connected at one end to the upper end face of the sliding plate 2, and the other end passes through the upper wall of the housing 1 and the upper wall of the dust cover 5 in sequence.

[0041] Compression spring A7 is wound and installed on the outer surface of piston rod 6, with one end in contact with the upper end face of housing 1 and the other end in contact with the inner upper end face of dust cover 5;

[0042] The fixing bolt 8 is set on the piston rod 6, and its lower end face is in contact with the upper end face of the dust cover 5;

[0043] The fixing bolt 8 is threadedly connected to the piston rod 6. At the same time, the compression spring A7 can apply an upward force to the dust cover 5. Under the action of the fixing bolt 8, the dust cover 5 can be fixed. At the same time, the dust cover 5 can block external impurities and prevent external debris from corroding the compression spring A7, thereby reducing the service life of the compression spring A7.

[0044] The cleaning mechanism is located on the upper end face of the housing 1 and is used to clean the outer surface of the dust cover 5.

[0045] Specifically, the cleanup agencies include;

[0046] An annular component 9 is disposed on the upper end face of the housing 1;

[0047] The annular inclined plate 10 is fixedly connected at one end to the upper end face of the annular part 9, and at the other end to the outer surface of the dust cover 5.

[0048] When the dust cover 5 slides into the annular groove 4, one end of the annular inclined plate 10 contacts the outer surface of the dust cover 5, scraping off the debris attached to the outer surface of the dust cover 5, preventing the debris from entering the annular groove 4 and causing blockage in the annular groove 4.

[0049] Brush bristles 11 are disposed on the inner surface of the annular part 9 and are in contact with the outer surface of the dust cover 5.

[0050] The bristles 11 are fixedly installed on the inner surface of the annular part 9. They can brush the outer surface of the dust cover 5 after the annular inclined plate 10 has scraped it, which can improve the cleaning effect and leave the residual impurities on the bristles 11, thus improving the cleaning effect on the outer surface of the dust cover 5.

[0051] Specifically, an annular placement groove 12 is formed on the upper end of the inner wall surface of the annular groove 4, and a sealing ring 13 is provided in the annular placement groove 12. The inner surface of the sealing ring 13 is in contact with the outer surface of the dust cover 5.

[0052] The sealing ring 13 can seal the gap between the inner wall of the annular groove 4 and the outer surface of the dust cover 5, which can further prevent impurities from entering the annular groove 4.

[0053] Specifically, the sealing ring 13 is a rubber sealing ring.

[0054] Specifically, the annular part 9 is provided with a connecting bolt 14, one end of which is threadedly connected to the housing 1;

[0055] The ring-shaped part 9 can be fixed to the housing 1 by the connecting bolt 14, making it convenient for workers to disassemble.

[0056] Specifically, a support plate 15 is provided at the bottom of the housing 1, a first ball head rod 16 is fixedly installed on the upper end face of the support plate 15, and a first hemispherical shell 17 connected to the first ball head rod 16 is fixedly installed on the lower end face of the housing 1.

[0057] The bearing plate 15 is equipped with fastening bolts, which can facilitate the connection between the bearing plate 15 and external equipment. At the same time, under the action of the first ball head rod 16 and the first hemispherical shell 17, the shell 1 can be flipped in four directions: forward, backward, left and right.

[0058] Above the bearing plate 15 and centered on the housing 1, there are two pairs of first fixing plates 18. One end face of the first fixing plate 18 is hinged to the outer wall of the housing 1. A first sleeve 19 is fixedly installed on one end face of the first fixing plate 18. An annular through groove 20 is formed in the outer wall of the first sleeve 19. A second sleeve 21 is slidably installed in the annular through groove 20. A second fixing plate 22 is fixedly installed on one end face of the second sleeve 21. A second hemispherical shell 23 is fixedly installed on one end face of the second fixing plate 22. A second ball head rod 24 connected to the second hemispherical shell 23 is fixedly installed on the upper end face of the bearing plate 15.

[0059] A limiting groove is formed on the inner wall of the annular through groove 20, and a limiting slider that is slidably connected to the limiting groove is fixedly installed on the outer wall of the second sleeve 21, which can prevent the second sleeve 21 from separating from the annular through groove 20.

[0060] A compression spring B25 is fixedly installed on the inner wall of the first sleeve 19, and the end of the compression spring B25 away from the first sleeve 19 is fixedly connected to the inner wall of the second sleeve 21.

[0061] When the housing 1 is flipped in one direction, a second sleeve 21 can slide into the annular groove 20 inside a first sleeve 19. At the same time, under the action of a compression spring B25, a force in the opposite direction can be exerted on the first sleeve 19 and the first fixing plate 18, which in turn exert a force on the housing 1 in one direction, thus absorbing shock. Meanwhile, under the action of two pairs of second hemispherical shells 23 and two pairs of ball-head rods 24, the other three first fixing plates 18, first sleeves 19, second sleeves 21 and second fixing plates 22 can be flipped.

[0062] Working principle: In actual use, the piston rod 6 can drive the fixing bolt 8 and the dust cover 5 to slide, causing the dust cover 5 to slide into the annular groove 4. At the same time, the compression spring A7 is compressed, and the sliding plate 2 slides inside the housing 1. The oil in the housing 1 flows through the through hole 3 to the top of the sliding plate 2, which can play a damping role. At this time, when the dust cover 5 slides into the annular groove 4, its outer surface contacts one end of the annular inclined plate 10, causing the annular sliding plate 10 to scrape off the impurities attached to the outer surface of the dust cover 5. At the same time, the bristles 11 can brush the dust cover 5 after it has been scraped by the annular inclined plate 10, which can further improve the cleaning effect of the outer surface of the dust cover 5. Moreover, the sealing ring 13 can also clean the annular groove 4. The gap between the inner wall of the groove 4 and the outer surface of the dust cover 5 is sealed to prevent impurities from entering the annular groove 4. At the same time, when the housing 1 is flipped in one direction, a second sleeve 21 can slide into the annular through groove 20 inside a first sleeve 19. Under the action of a compression spring B25, a force in the opposite direction can be exerted on the first sleeve 19 and the first fixing plate 18, which in turn exerts a force on the housing 1 in one direction, thus absorbing shock. At the same time, under the action of two pairs of second hemispherical shells 23 and two pairs of ball-head rods 24, the other three first fixing plates 18, first sleeves 19, second sleeves 21 and second fixing plates 22 can be flipped, bringing convenience to people.
