Description

Technical Field

[0001] The utility model relates to the technical field of indoor decoration, in particular to a lift for indoor decoration. Background Art

[0002] With the rapid development of social economy, interior decoration includes room design, decoration, furniture arrangement and various small decorations, focusing on the decoration construction inside the building. It not only takes place during the decoration design and construction period, but also includes long-term continuous decoration after moving in. A large amount of equipment is carried during decoration. Ordinary ladders can only allow a small amount of tools to be carried out for work, and climbing ladders when carrying equipment is very dangerous. Moreover, it is necessary to frequently go up and down the ladder to switch tools during work, which makes the efficiency low. At the same time, working on the ladder, there is no safety protection and accidents are prone to occur.

[0003] For example, an electric multifunctional elevator for indoor decoration (announcement number: CN220395589U), the device includes two guide grooves, screw rod one and screw rod two are respectively installed inside the two guide grooves, a large wheel belt is arranged at the same end position of screw rod one and screw rod two, a small wheel belt is connected between the two large wheel belts arranged at the same end through a conveyor belt transmission, the external transmission of the small wheel belt is connected to a driving motor, two groups of rising supports are arranged on the top of the two guide grooves, two ladders are arranged on the top of the two groups of rising supports, a workbench is installed on the top of the two ladders through a fixing pin, telescopic supports are arranged on the top of the workbench near the four corners, and a fencing mechanism is arranged on the outside of the four telescopic supports. The electric multifunctional elevator for indoor decoration makes efficient use of materials. After being converted into a table, the remaining parts can be moved to save space.

[0004] But the device still has the following defects:

[0005] When the device is in use, the interior of the guide rail groove lacks a mechanism for assisting in positioning the slider. When the height of the elevator is adjusted, the slider needs to move along the axial direction of the threaded rod. After the height adjustment of the elevator is completed, the threads of the slide rod and the screw rod will produce a large friction force, which may cause serious wear to the threads of the screw rod, which is not conducive to the long-term use of the elevator. Therefore, we need to propose an elevator for indoor decoration. Utility Model Content

[0006] The utility model aims to provide an indoor decoration elevator, aiming to solve the problem that the prior art lacks a mechanism for assisting the positioning of a slider. When the height of the elevator is adjusted, the slider needs to move along the axial direction of the threaded rod. After the height adjustment of the elevator is completed, the threads of the slide rod and the screw rod will generate a large friction force, which may cause serious wear to the threads of the screw rod, which is not conducive to the long-term use of the elevator.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A lift for indoor decoration comprises a base plate, on the top of which two groups of electric slides are symmetrically fixedly installed, two groups of sliders are slidably connected inside the two groups of electric slides respectively, a plurality of groups of first ratchets are equidistantly fixedly connected to the bottoms of the four groups of sliders respectively, and the inner bottoms of the two groups of electric slides are respectively provided with self-locking components that cooperate with the plurality of first ratchets to assist in positioning the sliders.

[0009] Preferably, the self-locking assembly includes several groups of return springs, the bottom ends of several groups of return springs are fixedly connected to the inner bottom of the electric slide, the top ends of several groups of return springs are fixedly connected to an adjustment plate, the top of the adjustment plate is fixedly connected to several groups of second ratchets at equal intervals, and several groups of second ratchets are meshed with several groups of first ratchets.

[0010] Preferably, two groups of connection blocks are fixedly connected to the side walls of both sides of the adjustment plate, and through grooves adapted to the connection blocks are opened on the side walls of the electric slide, and the connection blocks are slidably connected to the inside of the through grooves.

[0011] Preferably, it further comprises a pressing plate, wherein the pressing plate is fixedly connected to the bottom of the two groups of connecting blocks.

[0012] Preferably, slide grooves are respectively provided on the inner walls on both sides of the electric slide, and limit blocks corresponding to the slide grooves are respectively fixedly connected to the side walls on both sides of the slider, and the limit blocks are slidably connected to the inside of the slide grooves.

[0013] Preferably, the tops of the four groups of sliding blocks are respectively fixedly connected with first hinged seats, wherein the tops of two groups of the first hinged seats are hinged with first ladders, and the tops of the other two groups of the first hinged seats are hinged with second ladders.

[0014] Preferably, it further comprises a lifting platform, wherein four groups of second articulated seats are fixedly installed on the bottom of the lifting platform, wherein two groups of the second articulated seats are articulated to the first ladder, and the other two groups of the second articulated seats are articulated to the second ladder.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model arranges a first ratchet at the bottom of the slider and a self-locking component through the inner bottom of the electric slide. When the slider moves, the second ratchet can be squeezed downward by the first ratchet, thereby driving the adjusting plate to move downward, and then squeezing the reset spring. At this time, the reset spring is in a compressed state. As the slider continues to move, the resilience of the reset spring can lift the adjusting plate and the second ratchet so that the second ratchet re-engages with the first ratchet. When the slider moves to a suitable position, the second ratchet and the first ratchet will be in an engaged state, and the slider can be automatically locked, thereby reducing the friction generated by the slider and the thread on the screw rod, effectively reducing wear and tear, and facilitating the long-term use of the elevator.
