Technical Field
[0001] The utility model belongs to the field of lifting screen equipment, in particular to a spring-type semi-automatic lifting screen. Background Art
[0002] Because the screen itself is decorative, it can add beauty to the indoor environment, play a decorative role, and enhance the overall visual effect. Therefore, there are more and more screen manufacturers now, and the lift screen is a type of screen. The lift screen can provide privacy protection as needed, allowing users to isolate when needed to protect personal privacy. At the same time, the height of the screen can be adjusted as needed to achieve flexible space separation and layout adjustment to meet the needs of different occasions. Traditional lift screens are usually composed of multiple components, but the traditional lift screen has a complex mechanical structure, so the cost and maintenance cost are high, and regular maintenance is required to ensure normal use. Therefore, we hope to adopt a new structure and try not to use electrical components to achieve the lifting effect. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a spring-type semi-automatic lifting screen to solve the problems raised in the above-mentioned background technology.
[0004] The utility model is realized by the following technical scheme: a spring-type semi-automatic lifting screen, comprising: a column, a lifting plate sliding up and down along the column, the column has an inner cavity inside, a through hole is opened on the top of the column, and the top of the inner cavity is connected with the through hole;
[0005] Two symmetrically arranged sliding units are arranged inside the inner cavity, and the inner cavity is connected to the lifting plate through the sliding units. Driven by the constant force spring, the bottom of the lifting plate moves up and down along with the sliding units.
[0006] As a preferred embodiment, the sliding unit is composed of a slide rail installed on the inner surface of the inner cavity, and a slider slidably connected to the slide rail and can move up and down. The top of the slider is connected to the bottom of the lifting plate. When the lifting plate slides, the lifting plate moves up and down with the slider, and the slider moves up and down along the slide rail. The setting of the slider and the slide rail enables the lifting plate to have a certain sliding stroke and is more convenient to move up and down.
[0007] As a preferred embodiment, the bottom center of the lifting plate extends downward to form a lifting rod, and there are two constant force springs. The bottoms of the two constant force springs are symmetrically connected on both sides of the lifting rod. In actual use, when the lifting plate is in a falling state, the two constant force springs are in an extended state, and when the lifting plate is in a raised state, the two constant force springs are in a wound state.
[0008] As a preferred embodiment, the bottom of the lifting rod is vertically connected to a limit rod, and two buffers for limiting the limit rod are symmetrically arranged on both sides of the two constant force springs. When the lifting plate rises, its limit rod will eventually hit the two symmetrically arranged buffers. The two buffers limit the position of the limit rod, so that the lifting plate no longer rises. At this time, the lifting plate is in the highest state.
[0009] As a preferred embodiment, two symmetrically arranged self-locking switches are also provided in the inner cavity. The self-locking switch is a push-type opening or closing lock. The self-locking switch is composed of a self-locking device installed on the inner surface of the inner cavity and a self-locking head cooperating with the self-locking device.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1 The utility model provides a technical solution: a spring-type semi-automatic lifting screen, comprising: a column 100, a lifting plate 200 sliding up and down along the column 100, the column 100 has an inner cavity 110, a through hole 160 is opened on the top of the column 100, and the top of the inner cavity 110 is connected to the through hole 160;
[0020] Two symmetrically arranged sliding units 120 are arranged inside the inner cavity 110 . The inner cavity 110 is connected to the lifting plate 200 through the sliding units 120 . Driven by the constant force spring 150 , the bottom of the lifting plate 200 moves up and down along with the sliding units 120 .
[0021] The sliding unit 120 is composed of a slide rail 121 installed on the inner surface of the inner cavity 110, and a slider 122 slidably connected to the slide rail 121 and movable up and down. The top of the slider 122 is connected to the bottom of the lifting plate 200. When the lifting plate 200 slides, the lifting plate 200 moves up and down with the slider 122, and the slider 122 moves up and down along the slide rail 121 at this time. The setting of the slider 122 and the slide rail 121 enables the lifting plate 200 to have a certain sliding stroke, and it is more convenient to move up and down.
[0022] The bottom center of the lifting plate 200 extends downward to form a lifting rod 210, and there are two constant force springs 150. The bottoms of the two constant force springs 150 are symmetrically connected on both sides of the lifting rod 210. In actual use, when the lifting plate 200 is in a falling state, the two constant force springs 150 are in an extended state, and when the lifting plate 200 is in a raised state, the two constant force springs 150 are in a wound state.
[0023] like Figure 2 , Figure 4As an embodiment of the utility model, the bottom of the lifting rod 210 is vertically connected to a limit rod 211, and two buffers 140 for limiting the limit rod 211 are symmetrically arranged on both sides of the two constant force springs 150. When the lifting plate 200 rises, its limit rod 211 will eventually hit the two symmetrically arranged buffers 140. The two buffers 140 limit the position of the limit rod 211, so that the lifting plate 200 no longer rises. At this time, the lifting plate 200 is in the highest state.
[0024] like Figure 1 , Figure 3 As an embodiment of the utility model, two symmetrically arranged self-locking switches 130 are also provided in the inner cavity 110. The self-locking switch 130 is a push-type lock that is opened or closed. The self-locking switch 130 is composed of a self-locking device 131 installed on the inner surface of the inner cavity 110 and a self-locking head 132 that cooperates with the self-locking device 131. The two self-locking heads 132 are symmetrically installed below the lifting plate 200. When the lifting plate 200 moves downward to the lowest position, the self-locking head 132 is inserted into the self-locking device 131 to fix the position of the lifting plate 200, and at the same time, the two constant force springs 150 are in an extended state.
[0025] As an embodiment of the present invention, the lifting plate 200 moves up and down along the through hole 160. Specifically, in the initial state, the lifting plate 200 is located in the inner cavity 110. At this time, the self-locking head 132 is stuck in the self-locking device 131, and the constant force spring 150 is in a stretched state. The lifting plate 200 is pressed to transmit the force to the self-locking switch 130, and the self-locking head 132 is separated from the self-locking device 131. The lifting rod 210 moves upward under the action of the constant force spring 150, thereby driving the lifting plate 200 to move upward along the two sliding units 120. When the limit rod 211 contacts the buffer 140, the lifting plate 200 is in the highest position. At this time, the constant force spring 150 is in a coiled state, such as Figure 2 and Figure 4 .
[0026] When it is necessary to drop the lifting plate 200, the lifting plate 200 is continuously pressed downward to move the lifting plate 200 downward along the two sliding units 120 until the self-locking head 132 is locked in the self-locking device 131. Although the constant force spring 150 is in a stretched state at this time, because the self-locking head 132 is locked in the self-locking device 131, the position of the lifting plate 200 is fixed and cannot move upward, thus completing the operation of dropping the lifting plate 200.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
