Abstract
Description
Technical Field
[0001] The utility model relates to a car bottom structure, in particular to a villa ladder shallow pit car bottom structure which is easy to maintain. Background Art
[0002] As people's living standards improve, the demand for villa elevators is gradually increasing. Villa owners hope to improve the convenience and comfort of living by installing elevators, especially for the elderly and family members with limited mobility, elevators can greatly improve their quality of life. However, most self-built villas do not have a dedicated elevator shaft like passenger elevators. If they are installed later, there is no condition to dig a pit of the required depth; according to previous solutions: one is to make a single-layer car bottom without a car bottom shock-absorbing structure in the middle, and the height is relatively reduced; the other is to use the traditional passenger elevator shock-absorbing structure, compress the size of the car bottom and bracket, the internal space is small, the installation is inconvenient, and the replacement of the shock-absorbing pads later is also more troublesome. Utility Model Content
[0003] The utility model aims to provide a villa ladder shallow pit car bottom structure which is easy to maintain and has good shock absorption effect and convenient replacement of shock absorption pads.
[0004] The technical solution of the utility model is: a shallow pit car bottom structure for villa stairs which is easy to maintain, comprising a car bottom panel, a thick plate reinforcement frame is provided on the lower side of the car bottom panel, a plurality of evenly distributed tapping holes are provided on the lower side of the thick plate reinforcement frame, shock-absorbing pads are fixed in the tapping holes, a bottom support plate corresponding to the shock-absorbing pad is provided on the lower side of the bracket, and a locking bolt that passes through the bracket and fixes the shock-absorbing pad is provided in the bottom support plate.
[0005] In the aforementioned easy-to-maintain villa ladder shallow pit car bottom structure, the bottom support plate includes a horizontal plate, and side plates perpendicular to the horizontal plate are provided on both sides of the horizontal plate, and locking eyes for connecting the bracket are provided on the side plates.
[0006] In the aforementioned easy-to-maintain villa ladder shallow pit car bottom structure, the shock-absorbing pad includes a hollow cylindrical natural rubber sleeve, and base plates are provided on both sides of the upper side of the natural rubber sleeve. Connecting bolts perpendicular to the base plate are provided in the upper base plate, and the heads of the connecting bolts are located inside the natural rubber sleeve, and nuts are welded to the upper end of the lower base plate.
[0007] Compared with the prior art, the utility model realizes the connection between the car bottom panel and the bracket through the shock-absorbing pad, which can achieve a better shock-absorbing effect. When the shock-absorbing pad needs to be replaced, there is no need to remove the entire bracket. Instead, the locking bolt can be unscrewed so that the shock-absorbing pad can be rotated relative to the tapped hole and removed, making replacement more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the utility model;
[0009] Figure 2 It is a structural schematic diagram of the shock-absorbing pad of the utility model.
[0010] The markings in the attached drawings are: 1-car bottom panel, 2-thick plate reinforcement frame, 3-bracket, 4-shock-absorbing pad, 5-bottom support plate, 5.1-cross plate, 5.2-side plate, 5.3-locking eye, 5.4-locking bolt, 6-connecting bolt, 7-bottom plate, 8-natural rubber sleeve, 9-nut, 10-tapped hole. DETAILED DESCRIPTION
[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0012] Embodiment. A villa ladder with a shallow pit and a bottom structure that is easy to maintain, comprising: Figure 1 As shown, it includes a car floor panel 1, a thick plate reinforcement frame 2 is provided on the lower side of the car floor panel 1, a plurality of evenly distributed tapped holes 10 are provided on the lower side of the thick plate reinforcement frame 2, shock-absorbing pads 4 are fixed in the tapped holes 10, a bottom support plate 5 corresponding to the shock-absorbing pad 4 is provided on the lower side of the bracket 3, and locking bolts 5.4 are provided in the bottom support plate 5 which pass through the bracket 3 and fix the shock-absorbing pad 4.
[0013] The bottom support plate 5 comprises a transverse plate 5.1, and side plates 5.2 perpendicular to the transverse plate 5.1 are arranged on both sides of the transverse plate 5.1, and locking eyes 5.3 for connecting the bracket 3 are arranged on the side plates 5.2.
[0014] The shock-absorbing pad 4 includes a hollow cylindrical natural rubber sleeve 8, and base plates 7 are provided on both sides of the upper side of the natural rubber sleeve 8. A connecting bolt 6 perpendicular to the base plate 7 is provided in the upper base plate 7, and the head of the connecting bolt 6 is located inside the natural rubber sleeve 8. A nut 9 is welded to the upper end of the lower base plate 7.
[0015] Principle of the utility model: The application welds a thick plate reinforcement frame 2 under the car bottom panel 1, thereby reducing the thickness of the car bottom panel 1 while ensuring the strength. A plurality of evenly distributed tapping holes 10 are provided under the thick plate reinforcement frame 2 for connecting with the connecting bolts 6 in the shock-absorbing pad 4. The connecting bolts 6 can be hexagon socket cylindrical head bolts to realize the connection between the shock-absorbing pad 4 and the car bottom panel 1, and then the bottom support plate 5 is installed on the lower side of the bracket 3 through the locking eye 5.3 of the side plate 5.2 through the fixing piece, and the locking bolt 5.4 passes through the bottom support plate 5 and the bracket 3 and is connected with the nut 9 in the shock-absorbing pad 4, so that the bottom support plate 5 supports the shock-absorbing pad 4 to avoid damage to the bracket 3. The shock-absorbing pad 4 is separated from the thick plate reinforcement frame 2 and the bracket 3 up and down, has no rigid contact points, and has better shock-absorbing performance. When the shock-absorbing pad 4 needs maintenance and replacement, there is no need to disassemble the bracket 3 or the car bottom panel 1 as a whole. Only the locking bolt 5.4 needs to be unscrewed, and the shock-absorbing pad 4 is rotated to disengage the shock-absorbing pad 4 from the tapping hole 10 for replacement, which is convenient for maintenance.
