Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen support arm connection technology, and in particular to a connection structure between a screen and a support arm. Background Technology
[0002] With the continuous development of society and the continuous progress of technology, the technology related to screen bracket connection is also constantly improving. At present, most screens and tabletops are connected by a bracket. The rear end of the bracket is U-shaped and fits into one side of the screen hanging slot to realize the connection between the screen and the bracket.
[0003] When the tabletop is lifted, the support arm will rise along with the tabletop, which can easily cause the rear end of the support arm to detach from the hanging groove, resulting in the tabletop falling off due to loss of support. The tabletop has poor stability, and the connection between the screen and the support arm is not strong enough, which is not conducive to the connection between the screen and the support arm. Utility Model Content
[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: when the table is lifted, the support arm will rise with the table, which can easily cause the rear end of the support arm to come out of the hanging groove, resulting in the table falling off due to loss of support. The stability of the table is poor, and the connection between the screen and the support arm is not firm, which is not conducive to the connection between the screen and the support arm. Therefore, a connection structure for the screen and the support arm is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A connection structure for a screen and a support arm includes a screen body, a support arm body, two bolts, and a tabletop. The screen body has an installation groove, the support arm body has an installation cavity, a bent rod is slidably connected inside the installation cavity, and the upper inner wall of the installation groove has a slot for connecting the bent rod.
[0007] An installation plate is fixedly connected inside the mounting cavity. A sliding rod is slidably connected to the installation plate. An arc-shaped block is fixedly connected to one end of the sliding rod. A crossbar is fixedly connected to the bent rod. Multiple mounting holes for connecting the bolts are opened on the upper and lower inner walls of the mounting cavity.
[0008] Preferably, a vertical groove is formed on one side of the inner wall of the mounting cavity, and a first spring is fixedly connected to the lower inner wall of the vertical groove. The first spring and the bending rod are fixedly connected.
[0009] Preferably, a second spring is sleeved on the slide rod, one end of the second spring is fixedly connected to the slide rod, and the other end of the second spring is fixedly connected to the mounting plate.
[0010] Preferably, a reinforcing rod is fixedly connected to one end of the sliding rod, and a locking block for connecting the reinforcing rod is fixedly connected to one side surface of the screen body.
[0011] Preferably, the cross-section of the mounting groove is convex, and arc-shaped strips are fixedly connected to both the upper and lower surfaces of the support arm body, and arc surfaces are provided on both sides of the mounting groove.
[0012] Preferably, the upper and lower surfaces of the support arm body are fixedly connected to limit plates, and the surface of each limit plate is in contact with the surface of the screen body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] When the upper end of the bending rod engages with the slot, the support arm body cannot move relative to the screen body. Then, the tabletop is placed on the upper surface of the support arm body, and the two bolts are rotated to pass through the corresponding two mounting holes and connect with the lower surface of the tabletop. When one of the bolts moves into the interior of the mounting cavity, it will gradually move against the arc surface of the arc block, causing the arc block and the sliding rod to move simultaneously. After the sliding rod moves, its surface will fit against the lower surface of the horizontal bar, thus preventing the bending rod from moving downward and preventing the bending rod from detaching from the slot. This effectively prevents the support arm body and the screen body from separating. The connection between the support arm body and the screen body is relatively strong, effectively preventing the tabletop from falling off due to loss of support. The tabletop has high stability, and the connection between the screen body and the support arm body is relatively strong, which is beneficial to the connection between the screen body and the support arm body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0022] Reference Figures 1-4 A connection structure for a screen and a support arm includes a screen body 1, a support arm body 2, two bolts 5, and a tabletop 4. The screen body 1 has a mounting groove 8, and the support arm body 2 has a mounting cavity 12. A bent rod 6 is slidably connected inside the mounting cavity 12. The upper inner wall of the mounting groove 8 has a slot for connecting the bent rod 6. A mounting plate 11 is fixedly connected inside the mounting cavity 12. A sliding rod 14 is slidably connected to the mounting plate 11. An arc-shaped block 13 is fixedly connected to one end of the sliding rod 14. A crossbar 16 is fixedly connected to the bent rod 6. Multiple mounting holes for connecting bolts 5 are provided on both the upper and lower inner walls of the mounting cavity 12.
[0023] A vertical groove is provided on one side of the inner wall of the mounting cavity 12. A first spring 15 is fixedly connected to the lower inner wall of the vertical groove. The first spring 15 is fixedly connected to the bending rod 6. When the upper end face of the bending rod 6 is set face to face with the slot, the bending rod 6 will move up under the elastic force of the first spring 15 until the upper end of the bending rod 6 is engaged with the slot. At this time, the support arm body 2 cannot move relative to the screen body 1.
[0024] A second spring 10 is fitted on the slide rod 14. One end of the second spring 10 is fixedly connected to the slide rod 14, and the other end of the second spring 10 is fixedly connected to the mounting plate 11. When one of the bolts 5 passes through the mounting hole and moves into the interior of the mounting cavity 12, it will gradually move against the arc surface of the arc block 13, which will cause the arc block 13 to move away from the bolt 5. It will also cause the slide rod 14 and the mounting plate 11 to move relative to each other, and the second spring 10 will deform.
[0025] A reinforcing rod 3 is fixedly connected to one end of the sliding rod 14. A locking block for connecting the reinforcing rod 3 is fixedly connected to one side surface of the screen body 1. When the reinforcing rod 3 moves together with the sliding rod 14, the reinforcing rod 3 will move together until one end of the reinforcing rod 3 is engaged with the locking block. The reinforcing rod 3, the surface of the support arm body 2 and the surface of the screen body 1 are arranged in a triangle. The triangular support makes it easier for the support arm body 2 to better support the table surface 4.
[0026] The mounting groove 8 has a convex cross-section. Arc strips 7 are fixedly connected to the upper and lower surfaces of the support arm body 2. Arc surfaces are provided on both sides of the mounting groove 8. Limiting plates 9 are fixedly connected to the upper and lower surfaces of the support arm body 2. The surface of each limiting plate 9 is in contact with the surface of the screen body 1. One end face of the support arm body 2 is in contact with the inner wall of the mounting groove 8. Each arc strip 7 is in contact with the two arc surfaces of the mounting groove 8. After the two limiting plates 9 are in contact with the surface of the screen body 1, the support arm body 2 is pushed along the mounting groove 8. The two arc strips 7 will move along the arc surfaces. The friction between the arc strips 7 and the arc surfaces is small, so as to facilitate the rapid movement of the support arm body 2. The two limiting plates 9 can prevent the support arm body 2 and the screen body 1 from rotating relative to each other.
[0027] In this invention, during installation, the bending rod 6 is first pulled to allow it to slide relative to the support arm body 2 until the upper end of the bending rod 6 is completely retracted into the mounting cavity 12, causing the first spring 15 to deform. Then, one end of the support arm body 2 is inserted into the mounting groove 8 until the end face of the support arm body 2 is in contact with the inner wall of the mounting groove 8. At this time, each arc strip 7 is in contact with the two arc surfaces of the mounting groove 8, and both limiting plates 9 are in contact with the surface of the screen body 1. Then, the external force applied to the bending rod 6 is removed, and under the elastic force of the first spring 15, the bending rod 6 will move back until the upper end face of the bending rod 6 is in contact with the upper end face of the mounting groove 8. Then, the support arm body 2 is pushed along the mounting groove 8. When the upper end face of the bending rod 6 and the slot are face to face, under the elastic force of the first spring 15, the bending rod 6 will move upward until the upper end of the bending rod 6 is engaged with the slot. At this time, the support arm body 2 cannot move relative to the screen body 1.
[0028] Next, place the tabletop 4 on the upper surface of the support arm body 2, and then rotate the two bolts 5 respectively so that they pass through the corresponding two mounting holes and are threadedly connected to the lower surface of the tabletop 4. When one of the bolts 5 passes through the mounting hole and moves into the interior of the mounting cavity 12, it will gradually move against the arc surface of the arc block 13, which will cause the arc block 13 to move away from the bolt 5. It will also drive the slide rod 14 to move relative to the mounting plate 11, and the second spring 10 will deform. After the slide rod 14 moves, its surface will fit against the lower surface of the crossbar 16, which can prevent the bending rod 6 from moving down and prevent the bending rod 6 from separating from the slot. This effectively avoids the support arm body 2 and the screen body 1 from separating. The connection between the support arm body 2 and the screen body 1 is relatively firm, which effectively avoids the phenomenon that the tabletop 4 will fall off due to loss of support. The stability of the tabletop 4 is high, and the connection between the screen body 1 and the support arm body 2 is relatively firm, which is beneficial to the connection between the screen body 1 and the support arm body 2.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
