Description

Technical Field

[0001] The invention relates to the field of lifting equipment, and in particular to a lifting mechanism. Background Art

[0002] The lifting mechanism, also known as a lifting platform, is a lifting device that lifts people or goods to a certain height.

[0003] At present, lifting mechanisms are widely used in mechanical structures and electronic products. In order to achieve the lifting function, most common lifting mechanisms today are equipped with related linkage mechanisms. Specifically, the adjustment of the lifting height is achieved by using slide rails. Since other entities connected to the lifting mechanism are generally heavy, their gravity needs to be balanced so that the lifting mechanism can stop at any height for easy use. Most of the components used to generate the balancing force are fixed force springs (also called constant force coil springs). The tension of this spring is basically constant during the stretching process, which can better match the balance of other entities with constant gravity, so that the height of the display can be freely suspended during lifting.

[0004] The above-mentioned prior art solutions have the following defects: the lifting mechanism is not fixed in the hovering state, and the working position changes when disturbed by external conditions, causing the display connected to the lifting mechanism to move accordingly, affecting the stability of the display and resulting in a poor user experience. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a lifting mechanism having the advantage of a stable structure in a hovering state.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is as follows:

[0007] A lifting mechanism comprises a support body and a lifting component, wherein the lifting component is movably connected to the support body, and further comprises a control component and a locking component, wherein the locking component is detachably connected to the control component, and the control component is detachably connected to the support body, wherein the control component comprises a limiter, and the movement of the lifting component is controlled by the limiter, and when the locking component drives the limiter to be in a locked state, the limiter fixes the lifting component.

[0008] By setting it in this way, a control component and a locking component are provided outside the bracket body and the lifting component, wherein the locking component is detachably connected to the control component, and the control component is detachably connected to the bracket body. The control component includes a limiting member for controlling the movement of the lifting component, so that when the user uses the lifting mechanism, the limiting member can be used to control the movement of the lifting component, thereby reducing the occurrence of the situation that the position of the lifting mechanism changes due to the influence of the external environment, making the lifting mechanism have good stability when in different working positions, and further improving the user experience.

[0009] Preferably, the control component further includes a plurality of outer fixing frames, a plurality of guiding sheet metals and a plurality of inner fixing frames. The outer fixing frames and the inner fixing frames are detachably connected together with a gap left in the middle. The outer fixing frames and the inner fixing frames are both connected to the locking component. The limiting member includes a plurality of lifting racks and a plurality of control racks. The lifting racks are all movably arranged in the gap between the outer fixing frames and the inner fixing frames. The lifting racks are all connected to the lifting component. The middle parts of the guiding sheet metals are all connected to the inner fixing frames, and the bottoms of the guiding sheet metals are all connected to the locking component. The control racks are all detachably connected between the guiding sheet metals and the inner fixing frames. When the lifting component is in a fixed state, the lifting racks and the control racks are all engaged with each other.

The outer fixing frames and the inner fixing frames are both connected to the locking component. The limiting member includes a plurality of lifting racks and a plurality of control racks. The lifting racks are all movably arranged in the gap between the outer fixing frames and the inner fixing frames. The lifting racks are all connected to the lifting component. The middle parts of the guiding sheet metals are all connected to the inner fixing frames, and the bottoms of the guiding sheet metals are all connected to the locking component. The control racks are all detachably connected between the guiding sheet metals and the inner fixing frames. When the lifting component is in a fixed state, the lifting racks and the control racks are all engaged with each other. By changing the relative positions of the lifting racks and the control racks to control the movement of the lifting component, on the one hand, the stability of the lifting mechanism is improved, and on the other hand, the user can more precisely control the movement of the lifting mechanism.

[0011] Preferably, the locking component includes a bracket fixing member, a button fixing member, a button and a plurality of moving sheet metals. The bracket fixing member is detachably connected to the bottom of the bracket body. The button fixing member is detachably connected to the top of the bracket fixing member. The button is movably connected to the button fixing member. The plurality of moving sheet metals are respectively arranged on both sides of the button fixing member. One end of each moving sheet metal is detachably connected to the button, and the other end of each moving sheet metal is detachably connected to the guiding sheet metal.

[0013] Preferably, a compression spring is arranged on one side of the button fixing member close to the button, and the tension spring abuts between the button and the button fixing member.

[0014] By setting it in this way, a compression spring is arranged on one side of the button fixing member close to the button, and the tension spring abuts between the button and the button fixing member. On the one hand, the position of the button is fixed without external force, avoiding the interference of the lifting motion of the lifting assembly caused by the accidental position change of the button. On the other hand, the button can automatically rebound after being pressed by the user, simplifying the user's operation process and enabling the user to conveniently use the lifting mechanism.

[0015] Preferably, a button lock is further arranged between the button fixing member and the button. An activity channel is opened on the top surface of the button fixing member. The button lock is movably connected to the activity channel. When the button lock moves to the middle of the activity channel, the button lock abuts against the button.

[0016] By setting it in this way, a button lock is further arranged between the button fixing member and the button. An activity channel is opened on the top surface of the button fixing member. The button lock is movably connected to the activity channel. When the button lock moves to the middle of the activity channel, the button lock abuts against the button, so that the button will not easily change its position when subjected to external force accidentally, thereby improving the stability of the locking assembly and further improving the stability of the lifting mechanism.

[0017] Preferably, a spring support member is detachably connected to the top of the bracket main body. Constant force coil springs are arranged on both sides of the spring support member. One end of each constant force coil spring is detachably connected to the lifting assembly.

Constant force coil springs are arranged on both sides of the spring support member. One end of each constant force coil spring is detachably connected to the lifting assembly, so that the lifting speed of the lifting mechanism is slowed down, thereby improving the safety of the items carried by the lifting mechanism during the motion state.

[0019] Preferably, the lifting assembly includes a support top cover, multiple spring fixing plates, multiple slide rails, multiple fixed sheet metals, and multiple lifting optical axes. The upper halves of the multiple spring fixing plates are detachably connected to both sides of the support top cover respectively.

The lower halves of the multiple spring fixing plates are detachably connected to the constant force coil springs together. One end of the fixed sheet metal is detachably connected to the bottom of the support top cover. The multiple slide rails and the fixed sheet metals are movably connected together. One end of each lifting optical axis is detachably connected to the bottom of the support top cover. The lifting optical axes all pass through the spring support members. The other ends of the lifting optical axes are detachably connected to the lifting racks. Through the cooperation among the slide rails, the fixed sheet metals, and the lifting optical axes, the lifting mechanism can still move smoothly without losing stability.

[0021] Preferably, a bearing is detachably connected to the position of the guiding sheet metal close to the moving sheet metal, and the bearing abuts against the top of the moving sheet metal.

[0022] With such a setting, a bearing is detachably connected to the position of the guiding sheet metal close to the moving sheet metal, and the bearing abuts against the top of the moving sheet metal. Through the bearing and other related settings of the control assembly, the movement of the button is converted into the opening and closing movement of the rack, so that when the button is pressed, the rack opens, and thus the lifting mechanism can perform the lifting movement; when the button is released, the rack closes, and thus the lifting mechanism is fixed.

[0023] Preferably, a concave valley is provided at the top of the moving sheet metal, and the concave valley is an arc-shaped concave valley.

[0024] With such a setting, an arc-shaped concave valley is provided at the top of the moving sheet metal, so that the bearing can run smoothly and smoothly during the process of converting the movement trend, and the overall lifting mechanism can run smoothly and smoothly.

[0025] Preferably, the middle parts of the guiding sheet metals are connected to the inner fixing frame through elastic connecting members, and the elastic connecting members are tension springs.

[0026] By setting it in this way, the middle part of the guiding sheet metal is connected to the inner fixing frame through a tension spring, so that the process of converting the movement trend between the guiding sheet metal and the inner fixing frame can be carried out more gently, so that the lifting movement of the lifting mechanism can be carried out gently, and further reduce the occurrence of damage to the items carried by the lifting mechanism due to too violent lifting movement.
