Description

Technical Field

[0001] The utility model relates to the technical field of lifting brackets, in particular to a lifting bracket. Background Art

[0002] The application of lifting brackets is extremely extensive and can be seen everywhere in life. For example, temporary medical isolation houses, tents, RVs and other objects made of flexible fabrics often require lifting brackets to support them in order to be used better. Today's lifting brackets can be easily opened and stored, especially for RV tents that need to be frequently interchanged and deformed between the expanded and contracted states. The lifting brackets have a wide range of market value. The slider components of the lifting brackets have large sliding friction interface wear and low wear resistance. After long-term use, the slider components will deform, resulting in the lifting bracket operating smoothly, affecting its service life. In addition, when the slider components are severely worn, they often need to be replaced as a whole, resulting in a waste of resources. Utility Model Content

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 4In an embodiment of the utility model, a lifting bracket includes two guide plates 1 spaced apart from each other, and sliders 2 are slidably provided on opposite sides of the two guide plates 1. The front and rear sides of the sliders 2 extend downward to form lateral stops 21. A guide groove 22 is provided on the side of the lateral stopper 21 close to the guide plate 1. The side of the guide plate 1 is embedded in the guide groove 22. A gasket 3 is provided between the guide plate 1 and the inner wall of the guide groove 22. An X-shaped scissor-type bracket 4 is provided between the two guide plates 1. The upper and lower ends of the left side of the X-shaped scissor-type bracket 4 are respectively hinged to the two guide plates 1, and the upper and lower ends of the right side of the X-shaped scissor-type bracket 4 are respectively hinged to the two sliders 2.

[0019] The application method of the lifting bracket is as follows: two groups of lifting brackets are set on both sides of the roof, the lower guide plate 1 is installed on the roof, and the upper guide plate 1 is connected to the flat roof of the RV to be lifted. The folding state of the X-shaped scissor-type bracket 4 is adjusted manually through an added power device to drive the flat roof of the RV to rise and fall. During the lifting process, the slider 2 slides and rubs with the guide plate 1 through the gasket 3 to avoid direct contact with the guide plate 1, thereby reducing the wear of the slider 2. Even if the gasket 3 is worn, it is easy to replace, and the replacement of the entire slider 2 component can be avoided, effectively saving resources and reducing costs.

[0020] The front and rear sides of the guide plate 1 are flipped upward to form side flanges 11, and a guide ridge 12 is provided on the outer edge of the side flange 11. The guide ridge 12 is embedded in the guide groove 22. In this way, the surface of the side flange 11 and the guide ridge 12 form a straight track, and the slider 2 realizes directional sliding through the cooperation between the guide groove 22 and the guide ridge 12.

[0021] The guide groove 22 is in the shape of an inward-concave arc, the shape of the guide ridge 12 is adapted to the shape of the guide groove 22, the gasket 3 is in the shape of an arc, and the gasket 3 is wrapped around the guide ridge 12. The design of the embedded fit of the arc-shaped guide groove 22 and the arc-shaped guide ridge 12 makes the slider 2 more stable during movement and avoids swinging.

[0022] The outer surface of the gasket 3 is provided with several positioning blocks 31 along its circumference, and the inner wall of the guide groove 22 is provided with a positioning groove 23 that cooperates with the positioning block 31. One of the positioning blocks 31 is provided with a clamping column 32, and the side of the lateral stopper 21 is provided with a clamping hole 24 that communicates with the positioning groove 23. The clamping column 32 is inserted into the clamping hole 24. The gasket 3 is detachably fixed in the guide groove 22 through the clamping column 32, the clamping hole 24, the positioning block 31 and the positioning groove 23. After the gasket 3 is worn, the gasket 3 can be removed and replaced separately to save resources. The clamping hole 24 adopts a through-type structural design. When replacing the gasket 3, a tool can be used to extend into the clamping hole 24 from the outside of the guide block to push the gasket 3 out of the guide groove 22, which is convenient for replacing the gasket 3.

[0023] The inner wall of the gasket 3 is provided with a plurality of grooves 33 along its length direction, so that lubricating grease can be filled in the grooves 3 to provide good lubrication, reduce wear and improve stability.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
