[0030] Embodiment 1:
[0031] As Figure 1 shown, the present utility model discloses a screen up-and-down lifting mechanism, including a fixed seat 1, a support rod 2, a guide block 3, an adjusting bolt 4, and a pull rod 5. The fixed seat 1 is hinged to the rear section of the support rod 2, and the front end of the support rod 2 is connected to the screen. The following will specifically describe the main components of the above-presented present utility model:
[0032] As Figure 1 , Figure 2 and Figure 3 shown, a guide slideway 21 is provided along the axial direction inside the support rod 2.
[0033] As Figure 1 , Figure 2 and Figure 3 shown, the guide block 3 is slidably arranged inside the guide slideway 21 in the front-rear direction.
[0034] As Figure 1, Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the adjusting bolt 4 penetrates into the guide block 3 axially from the rear end of the support rod 2 and is movably connected thereto. The first nut 41, the second nut 42 and the limiting member 43 are sequentially connected to the outer thread of the adjusting bolt 4 from front to back. The first nut 41 and the second nut 42 are arranged to be movable back and forth inside the guide block 3; a first spring 41a is connected between the rear end of the first nut 41 and the guide block 3, and a second spring 42a is connected between the rear end of the second nut 42 and the guide block 3. The elastic force generated by the compression of the first spring 41a and the second spring 42a pushes the guide block 3 to move along the guide slideway 21; the limiting member 43 is detachably arranged in the support rod 2 for installing the adjusting bolt 4 in the support rod 2.
[0035] As Figure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , both ends of the pull rod 5 are respectively hinged to the fixed seat 1 and the guide block 3 through the cylindrical pins 6.
[0036] The usage method and principle of the present utility model are as described below:
[0037] When the screen needs to rise, rotate the adjusting bolt 4 to make the first nut 41 and the second nut 42 move backward to compress the first spring 41a and the second spring 42a. Under the action of the elastic force, the guide block 3 moves along the guide slideway 21 away from the screen side, providing a backward swinging force to the pull rod 5. During the backward swinging process of the pull rod 5, the guide block 3 will be driven to rise, and then the support rod 2 will swing upward, causing the screen connected to the front end of the support rod 2 to rise. The adjustment process is smooth. At the same time, due to the use of double springs for elastic force control, the bearing capacity provided by the support rod 2 is large enough.
[0038] When the screen needs to descend, rotate the adjusting bolt 4 to make the first nut 41 and the second nut 42 move forward to reduce the compression amount of the first spring 41a and the second spring 42a, reduce the elastic force received by the guide block 3, and reduce the force received by the pull rod 5 from the guide block 3. As a result, the pull rod 5 can no longer continue to support the support rod 2 and swings downward; then the support rod 2 swings downward to drive the screen to descend. During this process, the pull rod 5 will drive the guide block 3 to move along the guide slideway 21 toward the screen side, and as the guide block 3 moves, the first spring 41a and the second spring 42a will be compressed until the spring elastic force is balanced with the component force of the pull rod 5 in the direction of the guide slideway 21 again.
[0039] Embodiment 2:
[0040] As Figure 1 , Figure 2 and Figure 3As shown, to ensure that the support rod 2 can provide a greater bearing capacity for the screen, the first spring 41a is a large-spacing spring to provide a greater elastic force output range; the second spring 42a is a small-spacing spring to improve the stability of the elastic force output.
[0041] Embodiment Three:
[0042] As Figure 1 、 Figure 2 and Figure 3 shown, to improve the stability of the connection between the nut and the adjusting bolt 4, the adjusting bolt 4 includes a thin threaded rod section 4a and a thick threaded rod section 4b connected in sequence from front to back. The first nut 41 is threadedly connected to the outside of the thin threaded rod section 4a, and the second nut 42 is threadedly connected to the outside of the thick threaded rod section 4b.
[0043] Embodiment Four:
[0044] As Figure 1 、 Figure 2 and Figure 3 shown, to reduce the space occupied by the nut in the guide block 3, the first nut 41 and the second nut 42 are flat nuts.
[0045] Embodiment Five:
[0046] As Figure 1 、 Figure 2 and Figure 3 shown, to facilitate the disassembly and assembly of the guide block 3 and the adjusting bolt 4, the guide block 3 includes a left housing 31 and a right housing 32. The first nut 41 and the second nut 42 are respectively arranged in different cavities surrounded by the left housing 31 and the right housing 32; the left housing 31 and the right housing 32 are detachably connected together by a cylindrical pin 6. When installing the adjusting bolt 4, first pass the limiting member 43 and the second spring 42a through the adjusting bolt 4 in sequence, then screw the second nut 42 onto the thick threaded rod section 4b, then place the first spring 41a and then screw the first nut 41 onto the thin threaded rod section 4a at the front end. The above assembled components are placed in the left housing 31, then put the cylindrical pin 6 into the corresponding hole in the left housing 31, pass the pull rod 5 through the cylindrical pin 6, and close the right housing 32 for fixation.
[0047] Embodiment Six:
[0048] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, for the convenience of disassembly and assembly of the support rod 2, the guide block 3 and the adjusting bolt 4, the support rod 2 includes a left support housing 2a and a right support housing 2b. The left support housing 2a and the right support housing 2b enclose a guide slideway 21, and the left support housing 2a and the right support housing 2b are detachably connected together by a fastener 7. Put the assembled guide block 3 into the left support housing 2a, then hinge the fixed seat 1 at the fixed position at the tail of the left support housing 2a. At the same time, the cylindrical pin 6 connects the pull rod 5 and the fixed seat 1. Splice and combine the right support housing 2b with the left support housing 2a, and finally use the fastener 7 to lock the right support housing 2b and the left support housing 2a.
[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
