Description

Single motor corner structure

This creation relates to a cornering device, and more particularly to a single motor angler structure for use with a lifting table.

Press, common desks and desks, etc., the height of the desktop is mostly fixed and can not be adjusted, it is not suitable for users with different heights, and as human development evolves, it is gradually found that sedentary office is not conducive to the improvement of work efficiency. People began to try to sit and work alternately, so there is a lifting table, which not only adjusts the height of the table with the height of the user, in order to maintain a good sitting posture, ergonomics, and can make the office more liberal and help the human body. health.

However, the lifting mechanism of the conventional lifting table usually cannot stabilize the height of the ascending, descending and rest state, which often requires a plurality of reciprocating lifting to adjust the appropriate table height, and does not have a brake function, but is easy to have a gravity condition. The rotation is generated, causing inconvenience in use.

In view of the shortcomings of the above-mentioned lifting mechanism of the above-mentioned lifting table, the present creator introduced the creation after the idea of creating and testing the sample, and after many revisions and improvements.

The present invention provides a single-motor corner structure, comprising: an outer casing having an accommodating space therein, wherein each end surface is provided with a perforation communicating with the accommodating space, and the accommodating space is adjacent to the two perforations Each of the first bearing mounting portions is provided, and a through hole is formed in the peripheral edge of the outer casing to communicate with the accommodating space, and a second bearing mounting portion is disposed at the accommodating space and the through hole; the first bearing The second bearing is disposed in the second bearing mounting portion of the outer casing; the second bearing is disposed in the second bearing mounting portion of the outer casing; a shaft is disposed in the receiving space of the outer casing, Each of the two ends of the shaft rod is provided with a plurality of connecting holes, and the outer edges of the two ends of the shaft rod are respectively provided with a through portion, and a sleeve portion is arranged between the two through portions, and the sleeve portion and the piercing portion of one end of the shaft rod a coupling portion is disposed between the two ends of the shaft, and a first bevel gear is disposed on the linkage portion of the shaft to make the first umbrella shape a gear is coupled with the shaft; a second bevel gear set is disposed on the second bearing and the Between the rods, the second bevel gear is meshed with the first bevel gear; a brake sleeve is annular and sleeved on the sleeve portion of the shaft, and a side of the brake sleeve is provided a slot, the brake sleeve has a radial contraction elasticity; and a coil spring is sleeved on the outer circumference of the brake sleeve, and one end is bent outward to extend a positioning leg, and the positioning leg is positioned on the outer casing body, and the coil spring is elastic The brake sleeve is sandwiched so that the brake sleeve is radially contracted to tighten the sleeve portion of the shaft to achieve the braking effect.

The main purpose of the single motor corner structure is to stabilize and enhance the height of the ascending, descending and rest states, and to quickly and accurately adjust the required desktop height.

The second purpose of the design of the single motor corner device is that it utilizes a coil spring elastic clamping brake sleeve, so that the brake sleeve is radially contracted to tighten the shaft to achieve the braking effect, so that it has a good braking function and can have gravity Prevent rotation under conditions and improve ease of use.

The following description of the preferred embodiment of the present invention is further described below in order to enable those skilled in the art to practice the present invention to be implemented in accordance with the present specification.

The outer casing 10 is provided with an accommodating space 11 , and a through hole 12 is disposed on the two end faces to communicate with the accommodating space 11 . The accommodating space 11 and the two through holes 12 are respectively provided with a first bearing mounting portion 13 , and a through hole 14 is formed in the peripheral edge of the outer casing 10 to communicate with the accommodating space 11 . A second bearing mounting portion 15 is disposed at the intersection of the through holes 14.

The two first bearings 20 are respectively disposed on the two first bearing mounting portions 13 of the outer casing 10.

The second bearing 30 is assembled to the second bearing mounting portion 15 of the outer casing 10.

The shafts 40 are disposed in the accommodating space 11 of the outer casing 10. The two ends of the shaft 40 are respectively provided with a hexagonal connecting hole 41, and the outer edges of the shafts 40 are respectively provided. The sleeve portion 42 is disposed between the two through portions 42. The sleeve portion 43 and the through portion 42 of one end of the shaft are provided with a hexagonal interlocking portion 44. The shaft 40 is disposed. The through portions 42 at both ends are respectively inserted into the two first bearings 20 to be coupled.

The first bevel gear 50 is assembled on the linkage portion 44 of the shaft 40 such that the first bevel gear 50 is coupled with the shaft 40.

The second bevel gear 60 is disposed between the second bearing 30 and the shaft 40, and the second bevel gear 60 is meshed with the first bevel gear 50.

The brake sleeve 70 is formed in a ring shape and is made of a plastic material. The sleeve 70 is sleeved on the sleeve portion 43 of the shaft 40. The brake sleeve 70 is provided with a slot 71 to make the brake sleeve 70 have a diameter. The elasticity to contraction.

The coil spring 80 is sleeved on the outer circumference of the brake sleeve 70, and one end is bent outward to extend a positioning leg 81. The positioning leg 81 is positioned on the outer casing 10. In a normal state, the coil spring 80 elastically clamps the brake sleeve 70. The brake sleeve 70 is radially contracted to tighten the sleeve portion 43 of the shaft 40 to achieve a braking action.

When used, it can be applied to the lifting table 90 as shown in the fourth figure, so as to achieve the rise and fall adjustment of the table that drives the lifting table 90, but not limited thereto, it can also be applied to equipment such as electric beds, lift chairs, and the like. .

When the lifting adjustment is performed, when the shaft 40 rotates in one direction, the coil spring 80 and the brake sleeve 70 are radially expanded, and the first bevel gear 50 is coupled with the second bevel gear 60 to drive the lifting table. 90 stable and smooth lifting. After the adjustment, the brake sleeve 70 is elastically clamped by the coil spring 80, so that the brake sleeve 70 is radially contracted to tighten the shaft 40, and the friction between the inner surface of the brake sleeve 70 and the sleeve portion 43 of the shaft 40 is frictioned. Resistance, reaching the brake effect.

From the structure of the above specific embodiment, the following benefits can be obtained:

1. The original single motor corner structure can stabilize and enhance the height of the ascending, descending and rest state, and quickly and accurately adjust the required desktop height.

2. The single motor corner structure of the present invention uses the coil spring 80 to elastically clamp the brake sleeve 70, so that the brake sleeve 70 is radially contracted to tighten the shaft 40 to achieve the braking effect, so that the brake function is normally in the normal state, and the static state is The bearing capacity is stronger, and the rotation can be prevented under the condition of gravity, and the usability is improved.
