Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a hoisting device that can maintain a good damping effect. Background Technology

[0002] Generally, there is a certain damping effect between the lamp and the handle to reduce vibration and impact between them. For example, a Chinese utility model patent (publication number CN221665894U) discloses a lamp with a water ripple imaging structure, specifically in paragraph 0037 of the specification, which states that "to improve the damping experience when rotating the handle, wear-resistant nylon pads are provided on the two contact surfaces of the handle." Although the wear-resistant nylon pads have a certain degree of wear resistance, they still wear down with long-term rotation, resulting in a decreasing damping effect with increased rotation. To overcome the above-mentioned technical defects, this invention proposes a lifting device that can maintain a good damping effect. Summary of the Invention

[0003] To solve one of the above-mentioned technical problems, this invention provides a hoisting device that can maintain a good damping effect, which can maintain a long-lasting damping effect and has a long service life.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A hoisting device that can maintain a good damping effect includes a hanger and a fixing seat for fixed connection with the main body of the lamp. The hanger and the fixing seat are rotatably connected by a rotating shaft. A wear-resistant plate is passed through the rotating shaft and located between the hanger and the fixing seat. The hanger, the wear-resistant plate and the fixing seat compress each other to generate a damping effect. An elastic component is also provided between the hanger and the fixing seat to increase the damping effect of both.

[0006] Further defined, the elastic component includes a bowl-shaped elastic sheet passing through the rotating shaft, the wear-resistant sheet having a first through hole through which the rotating shaft passes, and when the hanger, the wear-resistant sheet and the fixed seat are pressed against each other, one end of the bowl-shaped elastic sheet passes through the first through hole and abuts against the fixed seat, and the other end abuts against the hanger.

[0007] Further defined, the elastic component includes a fixing plate passing through the rotating shaft, the wear-resistant plate having a thickness greater than the fixing plate, the fixing plate being adapted to the first through hole of the wear-resistant plate so that the wear-resistant plate is sleeved around the outer periphery of the fixing plate, and when the hanger, wear-resistant plate and fixing seat are pressed against each other, one end of the bowl-shaped elastic plate abuts against the fixing plate and the other end abuts against the hanger.

[0008] Further defined, the fixing piece is fixedly connected to the fixing base by a first fastener.

[0009] Further defined, the elastic component also includes a first washer passing through the rotating shaft, the first washer being located between the fixed piece and the cup-shaped elastic piece.

[0010] Further specified, the hanger is a U-shaped bracket.

[0011] Further specified, the mounting base is detachably connected to the lamp body via a quick-lock assembly.

[0012] Further defined, one end of the rotating shaft is fixedly connected to the fixed base, and the other end passes through the second through hole of the hanger and is threadedly connected to a second fastener.

[0013] Further defined, the other end of the rotating shaft passes through the second fastener and is sequentially provided with a pressure column and a third fastener. The pressure column has a hollow cavity for the second fastener to be accommodated. The other end of the rotating shaft passes through the hollow cavity of the pressure column and is threadedly connected to the third fastener. When the third fastener is locked, one end of the pressure column abuts against the hanger and the other end abuts against the third fastener.

[0014] Further specified, the third fastener is a knob handle.

[0015] After adopting the above technical solution, the present invention has at least the following beneficial effects: when the hanger and the fixed seat compress the elastic component, the compression of the elastic component generates a certain deformation stress, thereby further increasing the damping effect between the two. Even if the wear-resistant sheet is worn, it can still maintain a good damping effect under the deformation stress of the elastic component, thereby effectively preventing the defect of poor damping effect caused by the wear of the wear-resistant sheet and increasing the service life of the hoisting device.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] As attached Figure 1 To be continued Figure 3 As shown, a hoisting device that can maintain a good damping effect includes a U-shaped hanger 1 and a fixing seat 2 for fixed connection with the main body of the lamp. The hanger 1 and the fixing seat 2 are rotatably connected by a rotating shaft 3. A wear-resistant plate 4 is inserted through the rotating shaft 3 between the hanger 1 and the fixing seat 2. The wear-resistant plate 4 is preferably a nylon gasket. The hanger 1, the wear-resistant plate 4 and the fixing seat 2 are pressed against each other to generate a damping effect. An elastic component 5 is also provided between the hanger 1 and the fixing seat 2 to increase the damping effect of the two. When the hanger 1 and the fixing seat 2 compress the elastic component 5, the compression of the elastic component 5 generates a certain deformation stress, thereby further increasing the damping effect between the two. Even if the wear-resistant plate 4 is worn, it can still maintain a good damping effect under the deformation stress of the elastic component 5, thereby effectively preventing the defect of poor damping effect caused by the wear of the wear-resistant plate 4 and increasing the service life of the hoisting device.

[0022] As attached Figure 2 and attached Figure 3 As shown, the elastic component 5 includes a bowl-shaped elastic sheet 51 that passes through the rotating shaft 3. The cross-section of the bowl-shaped elastic sheet 51 is arc-shaped, and the two ends of the bowl-shaped elastic sheet 51 have openings of different diameters. The wear-resistant sheet 4 has a first through hole 41 through which the rotating shaft 3 passes. When the hanger 1, the wear-resistant sheet 4, and the fixed seat 2 are pressed against each other, one end of the bowl-shaped elastic sheet 51 passes through the first through hole 41 and abuts against the fixed seat 2, while the other end abuts against the hanger 1. Of course, the elastic component 5 may also include springs or other components with a certain degree of elasticity, but compared with other elastic components, the bowl-shaped elastic sheet 51 has good elasticity and can quickly return to its original shape after being subjected to force. It has advantages such as simple structure, convenient installation and replacement, low cost, and high cost performance.

[0023] In this embodiment, the elastic component 5 includes a fixing piece 52 passing through the rotating shaft 3. The fixing piece 52 is adapted to the first through hole 41 of the wear-resistant plate 4 so that the wear-resistant plate 4 is sleeved around the outer periphery of the fixing piece 52. When the hanger 1, the wear-resistant plate 4 and the fixing seat 2 are pressed against each other, one end of the bowl-shaped elastic plate 51 abuts against the fixing piece 52 and the other end abuts against the hanger 1. The end of the bowl-shaped elastic plate 51 with a larger opening diameter indirectly acts on the fixing seat 2 through the fixing piece 52, thereby increasing the effective area of ​​the bowl-shaped elastic plate 51.

[0024] Furthermore, the thickness of the wear-resistant plate 4 is greater than the thickness of the fixing plate 52, so that the first through hole 41 can simultaneously accommodate the bowl-shaped elastic plate 51, the fixing plate 52 and the first gasket 53. While the wear-resistant plate 4 is in pressure contact with the hanger 1 and the fixing seat 2 respectively, the elastic component 5 can also be in pressure contact with both of them.

[0025] In this embodiment, the fixing piece 52 is fixedly connected to the fixing seat 2 by a first fastener 6, preferably a screw. The fixing piece 52 and the fixing seat 2 are connected as one unit, so that the fixing piece 52 moves with the fixing seat 2, thereby increasing the force effect of the cup-shaped elastic piece 51 on the fixing seat 2.

[0026] In this embodiment, the elastic component 5 further includes a first washer 53 passing through the rotating shaft 3. The first washer 53 is located between the fixing piece 52 and the bowl-shaped elastic piece 51. The first washer 53 can increase the contact area between the fixing piece 52 and the bowl-shaped elastic piece 51, so that the force action of the bowl-shaped elastic piece 51 is better.

[0027] In this embodiment, the fixing base 2 is detachably connected to the lamp body via a quick-lock assembly 7. Specifically, the quick-lock assembly 7 mainly includes a handle, a pin connected to the handle, and a disc spring washer passing through the pin. The free end of the pin is provided with a locking pin. After the pin is inserted into the mounting hole of the lamp body, the handle drives the locking pin through the pin to engage with the locking position of the lamp body, thereby realizing the detachable connection between the fixing base 2 and the lamp body. The quick-lock assembly 7 is prior art known to those skilled in the art and will not be described in detail here.

[0028] In this embodiment, one end of the rotating shaft 3 is fixedly connected to the fixed seat 2, and the other end passes through the second through hole 100 of the hanger 1 and is threadedly connected to a second fastener 8. The second fastener 8 is preferably a nut. The nut and the rotating shaft 3 are locked together, so that a compressive force can be generated between the hanger 1 and the fixed seat 2. A second washer 11 is provided between the hanger 1 and the second fastener 8. The second washer 11 can increase the contact area and prevent loosening. The nut is threadedly locked with the external thread of the rotating shaft 3, so that the hanger 1, the fixed seat 2, the wear-resistant plate 4 and the elastic component 5 are mutually compressed to generate a damping effect.

[0029] In this embodiment, the other end of the rotating shaft 3 passes through the second fastener 8 and is sequentially fitted with a pressure post 9 and a third fastener 10. The pressure post 9 has a hollow cavity 101 for the second fastener 8 to be accommodated. The other end of the rotating shaft 3 passes through the hollow cavity 101 of the pressure post 9 and is threadedly connected to the third fastener 10. When the third fastener 10 is locked, one end of the pressure post 9 abuts against the hanger 1, and the other end abuts against the third fastener 10. A second washer 11 is provided between one end of the pressure post 9 and the hanger 1, and a third washer 12 is provided between the pressure post 9 and the third fastener 10. Similarly, the third washer 12 can also increase the contact area and prevent loosening. When the third fastener 10 is locked, the hanger 1 and the fixed seat 2 can be further locked, so that the hanger 1 and the fixed seat 2 are fixed to each other and prevent rotation.

[0030] In this embodiment, the third fastener 10 is a knob handle, which allows manual switching between the rotating and fixed states of the hanger 1 and the fixed base 2.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
