Description

Technical Field

[0001] The present invention relates to the technical field of display support, and in particular to a support frame quick-disassembly and quick-assembly structure and a display thereof. Background Art

[0002] At present, various displays have been widely used in today's life. Among them, liquid crystal displays have become the current mainstream products. Liquid crystal displays are a kind of display that is almost plate-shaped. They cannot stand on their own and must be supported by support devices such as support frames before they can be used.

[0003] Most existing support frames are sold in a disassembled state, with the base and columns separated to facilitate transportation and reduce packaging volume. Once consumers receive the product, they must install it themselves. Existing products have relatively complex structures and a cumbersome assembly process. Summary of the Invention

[0004] The object of the present invention is to provide a support frame quick-disassembly and quick-assembly structure and a display thereof, so as to solve at least one of the above-mentioned technical problems existing in the prior art.

[0005] In order to solve the above technical problems, the present invention provides a support frame quick-disassembly and quick-assembly structure, comprising: a base, a column, a wedge-shaped connecting block, a wedge-shaped sleeve, a return spring and a ball;

[0006] The wedge-shaped connecting block is fixedly arranged on the base;

[0007] The bottom of the column is provided with a mounting hole;

[0008] The side wall of the wedge-shaped sleeve is provided with a bead hole;

[0009] The bead hole passes through both sides of the side wall of the wedge-shaped sleeve;

[0010] The ball is rotatably embedded in the ball hole, and both ends of the ball protrude from both sides of the side wall of the wedge-shaped sleeve;

[0011] The wedge-shaped sleeve can be inserted into the mounting hole in a floating manner up and down;

[0012] The upright column is inserted into the wedge-shaped connection block through the mounting hole, and the wedge-shaped sleeve is sandwiched between the wedge-shaped connection block and the side wall of the mounting hole;

[0013] A working surface adapted to the ball is provided on the side wall of the mounting hole, and a gap between the working surface and the outer side surface of the wedge-shaped connecting block is a wedge-shaped space with a smaller bottom and a larger top;

[0014] The return spring is arranged in the mounting hole, and the two ends of the return spring respectively abut against the top of the wedge sleeve and the bottom of the mounting hole. The return spring tends to force the wedge sleeve to move downward with the ball, and the two ends of the ball respectively abut against the outer surface of the working surface and the wedge-shaped connecting block, thereby fixing the column on the wedge-shaped connecting block.

[0015] In the present application, the wedge-shaped connecting block is a frustum-shaped block with a larger bottom and a smaller top in a horizontal cross section; the inner hole of the wedge-shaped sleeve is a frustum-shaped block adapted to the wedge-shaped connecting block.

[0016] Furthermore, a window is provided on the side wall of the mounting hole, and an external force is used through the window to force the wedge-shaped sleeve to drive the ball to move upward, thereby releasing the locking state between the column and the wedge-shaped connecting block.

[0017] By using a tool such as a screwdriver or a metal roller, the wedge-shaped sleeve can be pried and moved upward by inserting it into the mounting hole through the window.

[0018] Furthermore, a slot is provided on the outer side wall of the wedge-shaped sleeve facing the window, or a paddle structure extending into the window is provided on the outer side wall of the wedge-shaped sleeve.

[0019] Use a tool to reach into the window and pry the wedge sleeve through the slot to move it, or lift the wedge sleeve through the prying structure.

[0020] Furthermore, it also includes a stroke limiting structure for limiting the up and down floating stroke of the wedge sleeve relative to the column.

[0021] Furthermore, the travel limiting structure includes a limiting groove or a limiting hole provided on the column or the wedge-shaped sleeve, and a limiting protrusion provided on the wedge-shaped sleeve or the column and adapted to the limiting groove or the limiting hole.

[0022] Preferably, a limiting hole is provided on the upright column, and a limiting protrusion (such as a limiting plate structure) adapted to the limiting hole is provided on the wedge-shaped sleeve. The limiting protrusion also serves as the above-mentioned paddle.

[0023] Furthermore, the horizontal cross-section of the wedge-shaped connecting block, the mounting hole and the wedge-shaped sleeve is rectangular.

[0024] Furthermore, the balls are embedded on the four side surfaces of the wedge-shaped sleeve.

[0025] In the height direction, a single side surface of the wedge-shaped sleeve is provided with one ball or a plurality of balls are provided at intervals.

[0026] Furthermore, the wedge-shaped connecting block is fixed to the base via connecting threads.

[0027] Furthermore, a connecting seat is provided on the base, and the wedge-shaped connecting block is fixed on the connecting seat via a clamping structure.

[0028] Furthermore, a plug-in hole is provided at the bottom of the wedge-shaped connecting block, and the wedge-shaped connecting block is inserted into the connecting seat through the plug-in hole. A snap-in groove is provided on the side of the connecting seat, and a pin hole is provided on the wedge-shaped connecting block. A snap pin or a snap bead is simultaneously inserted into the snap-in groove and the pin hole, thereby fixing the wedge-shaped connecting block and the connecting seat.

[0029] Furthermore, a compression spring is included. A compression spring is provided in the plug hole. Both ends of the compression spring rest against the wedge-shaped connecting block and the connecting seat, tending to force the wedge-shaped connecting block to move upward.

[0030] The compression spring can force the wedge-shaped connecting block to rest tightly against the connecting seat, solving the defect of loose connection caused by the existence of the assembly gap between the two, that is, the wedge-shaped connecting block will shake in a small range.

[0031] A second aspect of the present application discloses a display using the above-mentioned support frame quick-disassembly and quick-assembly structure.

[0032] By adopting the above technical solution, the present invention has the following beneficial effects:

[0033] The support frame quick-disassembly and quick-assembly structure and the display thereof provided by the present invention have a compact structure and can realize quick disassembly and quick assembly between the column and the base, greatly meeting the humanized needs of customers.

[0048] The present invention will be further explained below with reference to specific embodiments.

[0049] like Figure 1-7 As shown, the embodiment provides a quick-disassembly and quick-assembly structure of a support frame, comprising: a base 10 , a column 20 , a wedge-shaped connecting block 30 , a wedge-shaped sleeve 40 , a return spring 50 and a ball 60 .

[0050] The wedge-shaped connecting block 30 is fixedly arranged on the base 10; a mounting hole 21 is provided at the bottom of the column 20; a ball hole 43 is provided on the side wall of the wedge sleeve 40; the ball hole 43 passes through both sides of the side wall of the wedge sleeve 40; the ball 60 can be rollably embedded in the ball hole 43, and the two ends of the ball 60 protrude from the two sides of the side wall of the wedge sleeve 40; the wedge sleeve 40 can be inserted into the mounting hole 21 in a floating manner up and down; the column 20 is inserted into the wedge-shaped connecting block 30 through the mounting hole 21, and the wedge sleeve 40 is clamped between the wedge connecting block 30 and the side wall of the mounting hole 21; a working surface 22 adapted to the ball 60 is provided on the side wall of the mounting hole 21, and the gap between the working surface 22 and the outer side surface of the wedge connecting block 30 is a wedge-shaped space with a smaller bottom and a larger top.

[0051] The return spring 50 is arranged in the mounting hole 21, and the two ends of the return spring 50 respectively abut against the top of the wedge sleeve 40 and the bottom of the mounting hole 21. The return spring 50 tends to force the wedge sleeve 40 to move downward with the ball 60. The two ends of the ball 60 respectively abut against the outer surface of the working surface 22 and the wedge-shaped connecting block 30, thereby fixing the column 20 on the wedge-shaped connecting block 30.

[0052] In the present application, the wedge-shaped connecting block 30 is a frustum-shaped cone with a larger bottom and a smaller top in a horizontal cross section; the inner hole of the wedge-shaped sleeve 40 is a frustum-shaped cone that is adapted to the wedge-shaped connecting block 30 .

[0053] Furthermore, a window 23 is provided on the side wall of the mounting hole 21. Through the window 23, an external force is applied to force the wedge sleeve 40 to move the ball bearing 60 upward, thereby releasing the locking state between the column 20 and the wedge-shaped connecting block 30. A tool such as a screwdriver or metal roller can be inserted into the mounting hole 21 through the window 23 to pry the wedge sleeve 40 upward.

[0054] The outer wall of the wedge sleeve 40 is provided with a slot facing the window 23. A tool is inserted into the window 23 to pry the wedge sleeve 40 through the slot. Alternatively, the outer wall of the wedge sleeve 40 is provided with a prying structure 41 that extends into the window 23 and lifts the wedge sleeve 40.

[0055] Furthermore, a travel limiting structure is included to limit the vertical floating travel of the wedge-shaped sleeve 40 relative to the column 20. In this embodiment, the travel limiting structure includes a limiting hole provided on the column 20 and a limiting protrusion 42 provided on the wedge-shaped sleeve 40. The limiting protrusion 42 also functions as the aforementioned paddle structure 41.

[0056] The wedge-shaped connecting block 30, mounting hole 21, and wedge-shaped sleeve 40 have a rectangular horizontal cross-section. Balls 60 are embedded on all four sides of the wedge-shaped sleeve 40. In the height direction, a single side of the wedge-shaped sleeve 40 is provided with one ball 60 or with multiple balls 60 spaced apart.

[0057] The wedge-shaped connecting block 30 is fixed to the base 10 via connecting threads. Alternatively, a columnar or block-shaped connecting seat 70 is provided on the base 10, and the wedge-shaped connecting block 30 is fixed to the connecting seat 70 via a clamping structure.

[0058] See also Figure 8 As shown, in this embodiment, the wedge-shaped connecting block 30 has an insertion hole 31 at its bottom. The wedge-shaped connecting block 30 is inserted into the connecting seat 70 through the insertion hole 31. The connecting seat 70 has a snap-fitting groove 71 on its side. The wedge-shaped connecting block 30 is provided with a pin hole. A snap-fitting bead 80 (or a snap-fitting pin structure) is simultaneously engaged with the snap-fitting groove 71 and the pin hole, thereby fixing the wedge-shaped connecting block 30 to the connecting seat 70. Furthermore, a compression spring 81 is provided within the insertion hole 31. The ends of the compression spring 81 abut against the wedge-shaped connecting block 30 and the connecting seat 70, tending to force the wedge-shaped connecting block 30 to move upward.

[0059] The compression spring 81 can force the wedge-shaped connecting block 30 to rest tightly against the connecting seat 70, solving the defect of loose connection caused by the existence of the assembly gap between the two, that is, the wedge-shaped connecting block 30 will shake in a small range.

[0060] A second aspect of the present application discloses a display using the above-mentioned support frame quick-disassembly and quick-assembly structure.

[0061] The present invention has a compact structure and can realize quick disassembly and assembly between the column 20 and the base 10, greatly meeting the humanized needs of customers.
