Abstract
The utility model discloses an ascending and descending device used on furniture, which comprises a base, wherein the base is fixedly provided with a motor, the motor is connected with a screw rod via a transmission mechanism, the screw rod is sleeved with a bearing casing via upper and lower screw rod nuts, the upper end and the lower end of the bearing casing are respectively provided with a chain wheel, chains are arranged between the chain wheels, the chains are respectively meshed with a left support plate and a right support plate, the left support plate is fixedly connected with a pallet connected with a tabletop, and the right support plate is fixedly connected with the transmission mechanism. The utility model has compact structure, small installation size and large stroke, the lift height of the device is twice as much as the participation working section of the screw rod and the bearing casing, the speed is high, and when the device is used as the support leg of office furniture, an electronic device between support legs controls the synchronous operation of an electrical machine so as to maintain the ascending and descending mechanism at the same height in the operation process and meet the development requirements of modern office furniture.
Description
Technical field
The utility model belongs to a kind of lowering or hoisting gear, relates in particular to a kind of desk, computer desk, conference table etc. of being applied to and has in the office furniture of elevating function, as its supporting leg, lifts the lowering or hoisting gear of desktop lifting.
Background technology
At present in modern working environment, in the office furniture such as desk, computer desk, conference table, its height of table top is changeless basically, thereby be difficult to satisfy the pursuit of people to high-quality life, so occurred having the furniture of elevating function on the market, these furniture have two or more supporting leg usually, adopt synchronization lifting to keep the up and down balance system of desktop.
Existing lowering or hoisting gear, its structure comprise setting of casing and last sleeve pipe, and last sleeve pipe places setting of casing, the setting of casing inner tubal wall has internal thread, and last sleeve pipe has external screw thread, being threaded between external screw thread and the internal thread, the upper and lower displacement of sleeve pipe in setting of casing in the realization, and then the lifting of realization furniture.But furniture is in lifting process, and the seat or the desktop that are connected with last sleeve pipe need rotate, and the screw thread on last sleeve pipe and the setting of casing also deforms easily, causes furniture lifting running freely not suitable, thereby is difficult to meet people's instructions for use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, furniture lowering or hoisting gear that reliability is high.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of lowering or hoisting gear that is used on the furniture, it comprises base, be installed with motor on the base, motor is connected with screw mandrel by transmission mechanism, and described screw mandrel is set with carrying sleeve by feed screw nut up and down, and two ends is respectively arranged with sprocket wheel about the carrying sleeve, be provided with chain between the sprocket wheel, chain is meshed with left and right sides support plate respectively, and described left supported plate is fixedly connected with the supporting plate that is connected desktop, and described right supported plate is fixedlyed connected with transmission mechanism;
As improvement of the technical scheme, described motor is a d.c. motor; Be provided with the motor register in the described motor;
As further improvement in the technical proposal, described transmission mechanism includes the internal gear that is connected with motor drive shaft, and internal gear is meshed with planetary gear, and planetary gear is outside equipped with the planetary gear location-plate, and the planetary gear location-plate is fixedlyed connected with reduction box;
Further, about described sprocket wheel and chain are divided into two groups.
The beneficial effects of the utility model are: the utility model compact conformation, installation dimension is little, stroke is big, it is lifted highly is the twice that screw mandrel and carrying sleeve participate in active section length, speed is fast, with its supporting leg as office furniture, controls synchronizing motors by electronic installation between the supporting leg, make elevating mechanism in running, remain equal height, thereby adapt to the demand for development of modern Office Furniture.

The specific embodiment
With reference to Fig. 1 ~ Fig. 6, a kind of lowering or hoisting gear that is used on the furniture, it comprises base 1, be installed with motor 2 on the base 1, described motor 2 is a d.c. motor, and motor 2 is connected with screw mandrel 4 by transmission mechanism 3, described transmission mechanism 3 includes the internal gear 31 that is connected with motor drive shaft, internal gear 31 is meshed with planetary gear 32, and planetary gear 32 is outside equipped with planetary gear location-plate 33, and planetary gear location-plate 33 is fixedlyed connected with reduction box 34.Certainly, transmission mechanism 3 also is not limited to above-mentioned technical scheme, also can adopt other common technology types, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model in a word.
Described screw mandrel 4 overlaps 41,42 by feed screw nut up and down and is set with carrying sleeve 5, carrying sleeve about in the of 5 two ends be respectively arranged with sprocket wheel 61,62, be provided with chain 7 between the sprocket wheel 61,62, chain 7 is meshed with left and right sides support plate 81,82 respectively, in order to make product motion more stable, about described sprocket wheel 61,62 and chain 7 are divided into two groups.Described left supported plate 81 is fixedly connected with the supporting plate 9 that is connected desktop, and described right supported plate 82 is fixedlyed connected with reduction box 34.
For reaching two groups even the use simultaneously of many groups, increase a motor register 21 in motor 2 back and make it to reach synchronous effect by controller.
The operation principle of this product is: rotate after motor 2 is connected power supply, drive screw mandrel 4 rotations by transmission mechanism 3, rising or decline that screw mandrel 9 rotates, make left supported plate 81 rise or descend with motor 2, because left supported plate 81 rises and chain 7 is meshing with each other, chain 7 is by sprocket wheel 61,62 feed screw nuts up and down that are fixed on carrying sleeve 5 overlap 41, on 42, and chain 7 and right supported plate 82 engagements, thereby just form left and right sides support plate 81,82 move toward one another, make it to reach the increase flight effects, the utility model compact conformation, installation dimension is little, stroke is big, and it is lifted highly is the twice that screw mandrel 4 and carrying sleeve 5 participate in active section length, and speed is fast, with its supporting leg as office furniture, by electronic installation control synchronizing motors, make elevating mechanism in running, remain equal height between the supporting leg, thereby adapt to the demand for development of modern Office Furniture.
