Description

With enhanced stability lifting mechanism

This creation is about a lifting mechanism, especially a stabilizing lifting mechanism for a lifting table.

According to common desks and desks, the height of the desk is mostly fixed and cannot be adjusted. It is not suitable for users of different heights. In addition, with the evolution of human development, it is gradually found that sitting in the office is not conducive to improving work efficiency. , People began to try to sit and stand alternately, so there is a lifting table, which not only can adjust the height of the desktop with the height of the user to maintain a good sitting posture, ergonomics, and can make the office more liberalized, help Human health.

However, the lifting mechanism of the conventional lifting table is usually unable to stabilize the height of the lifting, lowering, and stationary state, which often requires multiple reciprocating lifts to adjust the appropriate table height, and it does not have a braking function, and the lifting capacity is poor. Causes inconvenience in use.

In view of the shortcomings of the above-mentioned lifting mechanism of the conventional lifting table, the creator launched this creation after researching and experimenting with sample ideas from various parties and revising and improving many times.

The creation provides a lifting mechanism with enhanced stability, including: a lifting rod group provided with a support rod, a screw protruding upward in the support rod is screwed, and the screw can be lifted and lowered relative to the support rod by rotating the screw For adjustment, the upper end of the screw is provided with a sleeve section and an engaging part located on the upper side of the sleeve section; a bearing is sleeved outside the sleeve section of the upper end of the screw; a bearing seat is provided with a slotted hole portion, the slot The hole part provides the bearing accommodation and the threading section of the upper end of the screw; an end cap is covered and fixed on the top surface of the bearing seat, and the bearing is limited to the slot hole part of the bearing seat. The end cap has a A cover hole for the engaging part of the upper end of the screw to extend; a transmission member, a lower part is provided with a sleeve part, an intermediate through hole is provided in the middle, and a plurality of claws are provided at the upper end, the connecting hole is for the screw The upper part of the engaging part is inserted and fixed, and the screw can be rotated and screwed by the transmission member, so that the screw can be adjusted up and down relative to the support rod; and a coil spring is sleeved on the transmission member. Outer periphery of sleeve End a locating pin extending outwardly bent, the positioning pin positioned in the end cap but may be sandwiched by the coil spring elastically supporting beam portion cover member of the transmission, to achieve braking action.

The main purpose of this creation is to strengthen and stabilize the lifting mechanism, which can stabilize and strengthen the height of the lifting, lowering and stationary state, and quickly and accurately adjust the required height.

The second purpose of this creation is to strengthen and stabilize the lifting mechanism. It uses the coil spring to elastically clamp the sleeve part of the transmission part to achieve the braking effect. Therefore, it has a good braking function, a large bearing capacity in the static state, and an improved convenience.

The following is further explained in conjunction with the drawings of the preferred embodiment of this creation, in order to enable those familiar with the relevant technology of this creation to implement according to the statements in this specification.

First, please refer to the first, second, third, fourth, and fifth drawings. This creation is a lifting and stabilizing lifting mechanism. The lifting and stabilizing lifting mechanism 1 includes: a lifting rod group 10, a bearing 20, and a bearing. The base 30, one end cover 40, a transmission member 50 and a coil spring 60.

The lifting rod group 10 is provided with a support rod 11. A screw 12 protruding upward is screwed in the support rod 11. The screw 12 can be adjusted by rotating and screwing relative to the support rod 11. The upper end of the screw 12 is provided. A through-hole section 121, an engaging portion 122 on the upper side of the through-hole section 121, and a screw hole 123 on the top surface of the engaging portion 122. The cross-section of the engaging portion 122 is hexagonal.

The bearing 20 is sleeved outside the sleeve section 121 at the upper end of the screw 12.

The bearing housing 30 is provided with a slotted hole portion 31 and a locking piece portion 32 formed to extend outward along the top edge of the slotted hole portion 31. The slotted hole portion 31 provides the bearing 20 accommodation and a sleeve section at the upper end of the screw 12. 121 is passed through, and the engaging portion 122 at the upper end of the screw 12 projects above the slot hole portion 31.

The end cover 40 is fixed on the top surface of the bearing housing 30 and is fixed. The bearing 20 is limited to the slot 31 of the bearing housing 30. The end cover 40 has a cover hole 41 for the screw. The upper end of the engaging portion 122 extends through, and at least one engaging groove 411 is provided on the periphery of the cover hole 41. Two opposite engaging grooves 411 are provided on the periphery of the cover hole 41 in this embodiment.

The transmission member 50 is provided with a cylindrical sleeve portion 51 at the lower end, an interlocking hole 52 penetrating axially in the middle, and a plurality of claws 53 at the upper end. Close, and pass a screw 54 through the interlocking hole 52 of the transmission member 50, and screw-lock with the screw hole 123 of the screw 12, so that the transmission member 50 is fixed with the screw 12, and can be linked by the transmission 50 The screw 12 is rotated and screwed, so that the screw 12 is adjusted upward and downward relative to the support rod 11.

The coil spring 60 is sleeved on the outer periphery of the sleeve portion 51 of the transmission member 50, and one end is bent outward to extend a positioning leg 61. The positioning leg 61 is inserted into the slot 411 of the end cover 40 for positioning. The spring 60 elastically clamps the sleeve portion 51 of the transmission member 50 to achieve the braking effect.

In use, a group of the lifting and stabilizing lifting mechanism can be set in the two table legs 2A of the lifting table 2, and the claws 53 of the transmission member 50 can be connected with the motor group of the lifting table 2 to be driven by the motor group. The transmission member 50 rotates in the forward and reverse directions, and the transmission member 50 rotates the screw 12 in conjunction with the rotation of the screw 12 so that the screw 12 is adjusted up and down relative to the support rod 11, thereby driving the lifting table 2 to move smoothly and smoothly. The spring 60 expands radially due to the rotation of the transmission member 50.

After the lifting adjustment, the coil spring 60 will contract the sleeve portion 51 of the transmission member 50 due to its elastic radial contraction, and pass the friction resistance between the coil spring 60 and the sleeve portion 513 of the transmission member 50. Reach braking.

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

1. This creation has a stabilizing lifting mechanism, which can stabilize and strengthen the height in ascending, descending, and stationary states, and quickly and accurately adjust the required height.

2. This creation has a stabilizing and lifting mechanism, which utilizes the sleeve portion 513 of the coil spring 60 to elastically clamp the transmission member 50 to achieve the braking effect. Therefore, it has a good braking function in the normal state, and has a large bearing capacity in the static state. Under the condition of gravity, the screw 12 is prevented from falling arbitrarily, and the convenience of use is improved.
