Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brackets, in particular to a screen bracket. Background Art
[0002] Currently, most public places (such as subway waiting rooms, train waiting rooms, and hospital waiting rooms) are equipped with information display screens to convey information. The information display screens are usually fixed on the wall. These places are basically equipped with seats. If the seats are against the wall, the screen cannot be seen. If the seats are far away from the screen, it is inconvenient to watch and the promotional effect is poor. Therefore, there is a situation in the existing technology where the information display screen is set next to the seat, but the setting method of this screen is usually fixed and cannot be effectively adjusted to cope with various situations. Summary of the Invention
[0003] In order to solve the problem that most existing information display screens are fixedly installed next to the seats and cannot be adjusted, the utility model proposes a screen bracket, which is hinged by a first support rod and a second support rod. When the second support rod rotates toward the side of the seat, the gas spring is compressed, and the transmission structure provided on the second support rod drives the first fixed rod to rotate, thereby realizing the rotation of the screen. At this time, the display screen is in front of the person sitting on the chair, and the screen position is lowered relative to the upright state, making it easier for them to watch the screen.
[0004] To achieve the above-mentioned object, the technical solution of the present invention is as follows: a screen bracket, comprising a bracket body arranged on one side of a seat, the bracket body comprising a first support rod and a hollow second support rod, the second support rod being located above the first support rod, the upper end of the first support rod being hinged to the lower end of the second support rod via a hinge rod, the bracket body being provided with a gas spring, one end of the gas spring being fixed to the first support rod and the other end being fixed to the second support rod, the second support rod also being provided with a first fixing rod for fixing the display screen, the first fixing rod being rotatably connected to the second support rod, the end of the first fixing rod proximate to the second support rod being fixed with a connecting shaft extending into the second support rod, the second support rod being provided with a transmission mechanism for rotating the first fixing rod. When the second support rod rotates, the transmission mechanism drives the first fixing rod to rotate synchronously, the provision of the gas spring further limits the rotation angle of the second support rod, and the gas spring stores a portion of force when compressed, making reset easier.
[0005] Furthermore, the transmission mechanism includes a first bevel gear, a rotating shaft and a second bevel gear. The first bevel gear is provided on the hinged rod and the connecting shaft, and second bevel gears meshing with the first bevel gear are provided at both ends of the rotating shaft. A fixed block is provided inside the second support rod, and the fixed block is rotatably connected to the rotating shaft.
[0006] Furthermore, the transmission mechanism includes a disk, a connecting rod, and a second fixed rod. The disk is fixedly mounted on one end of the connecting shaft that extends into the second support rod and on the hinge rod. The second fixed rod is fixed to each of the two disks. Both ends of the connecting rod are rotatably connected to the second fixed rod. The connecting shaft is rotatably connected to the second support rod, and the end of the connecting shaft that extends into the interior of the second support rod does not contact the side wall of the second support rod, thereby avoiding interference with the position of the connecting rod.
[0007] Furthermore, a stabilizing device is provided at the lower part of the first support rod, and the stabilizing device includes a stabilizing block, a supporting block and a limiting structure fixed to the stabilizing block on the side close to the seat. The stabilizing device is located on the rear side of the seat, one end of the stabilizing block is fixedly connected to the first support rod, and the support block is located below the stabilizing block and fixedly connected to the stabilizing block.
[0008] Furthermore, the retaining structure includes an L-shaped first cylinder, a second cylinder, and a stabilizing plate. The first cylinder is fixed to the stabilizing block, while the second cylinder's lower end is threadedly connected to the first cylinder's upper end and its upper end is hingedly connected to the stabilizing plate. The chair and the stabilizing block assist in supporting the stand body, improving its stability. The second cylinder is threadedly connected to the first cylinder, allowing it to extend and retract, allowing the stabilizing plate to support the lower portion of the chair.
[0009] Furthermore, the second support rod is provided with a handle.
[0010] Furthermore, the support block is a conical structure.
[0011] Furthermore, the first support rod is a telescopic structure, so that the screen height can be adjusted during actual use.
[0012] Furthermore, the angular rotation range of the second support rod is 0-90°.
[0013] Through the above technical solution, the beneficial effects of the present invention are as follows: the first support rod and the second support rod of the present invention are hinged, and gas springs are provided on the first support rod and the second support rod. In the initial state, the second support rod is in an upright state, and the screen on the first fixed rod is also in an upright state, which takes up less space and can be viewed by most passers-by. When the second support rod rotates and compresses the gas spring to 90 degrees, the fixed frame and the screen are also adjusted with the rotation of the transmission structure. At this time, the display screen is in front of the person sitting on the chair, and the screen position is lowered relative to the upright state, which improves the viewing experience of the person on the chair. When the screen is manually reset, part of the force stored in the gas spring is released, and the gas spring drives the rotation of the second support rod to save effort. At the same time, the transmission structure also drives the first fixed rod to rotate in the opposite direction to reset. The overall structure adopts a purely mechanical structure, and the production cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0023] Example 1
[0024] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, this embodiment provides a screen bracket, including a bracket body arranged on one side of the seat 1, the bracket body including a first support rod 2 and a hollow second support rod 3, the second support rod 3 is located above the first support rod 2, the upper end of the first support rod 2 and the lower end of the second support rod 3 are hinged by a hinge rod 5, and a gas spring 4 is provided on the bracket body, one end of the gas spring 4 is fixed on the first support rod 2, and the other end is fixed on the second support rod 3, and the second support rod 3 is also provided with a first fixing rod 6 for fixing the display screen, the first fixing rod 6 is rotatably connected to the second support rod 3, and the first fixing rod 6 is fixed with a connecting shaft 7 extending into the second support rod 3 at one end close to the second support rod 3, and the second support rod 3 is provided with a transmission mechanism for rotating the first fixing rod 6.
[0025] Specifically, the transmission mechanism includes a first bevel gear 21, a rotating shaft 22, and a second bevel gear 23. The first bevel gear 21 is fixed on the hinged rod 5 and the connecting shaft 7. The second bevel gear 23 meshing with the first bevel gear 21 is fixed at both ends of the rotating shaft 22. A fixed block 24 is provided inside the second support rod 3. A ring groove is provided at the connection portion of the rotating shaft 22 with the fixed block 24. The fixed block 24 is clamped in the ring groove and is rotatably connected to the rotating shaft 22. A handle 16 is provided on the second support rod 3, and the hinged rod 5 is fixed to the first support rod 2.
[0026] When people want to sit on the chair and watch the screen, they manually pull the handle 16 to drive the second support rod 3 to rotate 90 degrees toward one side of the seat 1. During this process, the gas spring 4 will be in a continuously compressed state. At the same time, the hinged rod 5, the connecting shaft 7 and the transmission mechanism drive the first fixed rod 6 to rotate 90 degrees relative to the second support rod 3. During this process, the first bevel gear 21 and the hinged rod 5 do not rotate, and then the second bevel gear 23 on the rotating shaft 22 engaged with the first bevel gear 21 rotates with the rotation of the second support rod 3, and then drives the first bevel gear 21 fixed on the connecting shaft 7 to rotate, thereby causing the first fixed rod 6 to rotate so that the screen is facing the seat 1, making it convenient for the person sitting on the seat 1 to watch the content on the screen. When it is not needed to watch, the hand holds the handle 16 and applies force upward, and the second support rod 3 rotates 90 degrees in the opposite direction to the upright state. At this time, the hinged rod 5, the connecting shaft 7 and the transmission mechanism also drive the first fixed rod 6 to rotate 90 degrees in the opposite direction relative to the second support rod 3 to reset.
[0027] In this embodiment, the display screen can sense gravity to achieve screen flipping, thereby adapting to two different situations.
[0028] In this embodiment, the bracket body is located on the rear side of the seat 1 and is in an upright state on the first fixed rod 6, occupying a small space. The screen thereon can be viewed by most passers-by. When the second support rod 3 is rotated 90 degrees, the screen faces the seat 1, and the height of the screen is lowered, thereby better improving the viewing effect for people on the seat.
[0029] Gas spring 4 can be made of 304 / 316 stainless steel gas spring from Yinjiang gas spring. Figure 6 As shown, the second support rod 3 has an angular rotation range of 0-90 degrees. When the second support rod 3 is rotated 90 degrees, the end surface of the second support rod 3 contacts the side surface of the first support rod 2, achieving a locking effect and preventing the second support rod 3 from further rotation. At this time, the role of the gas spring 4 can be ignored. When the second support rod 3 is upright, the gas spring 4 mainly plays a pulling role.
[0030] In this embodiment, as the second support rod 3 rotates 90 degrees, the first fixed rod 6 also rotates 90 degrees driven by the transmission structure by controlling the tooth torque of the first bevel gear 21 and the second bevel gear 23. This is a prior art and will not be described in detail. When there is a requirement for the rotation angle of the first fixed rod 6, it can be achieved by using bevel gears of different designs.
[0031] As an implementable method, Figure 4 As shown, a stabilizing device is provided at the lower portion of the first support rod 2. The stabilizing device includes a stabilizing block 11, a support block 12, and a limiting structure fixed to the stabilizing block 11 on the side near the seat 1. The stabilizing device is located at the rear side of the seat 1. One end of the stabilizing block 11 is fixedly connected to the first support rod 2. The support block 12 is located below the stabilizing block 11 and is fixedly connected to the stabilizing block 11. The limiting structure includes an L-shaped first cylinder 13, a second cylinder 14, and a stabilizing plate 15. The first cylinder 13 is fixed to the stabilizing block 11. The lower end of the second cylinder 14 is threadedly connected to the upper end of the first cylinder 13, and the upper end is hinged to the stabilizing plate 15. The support block 12 is a conical structure. The stabilizing plate 15 is hinged to the second cylinder 14. When it adapts to the seat, the stabilizing plate 15 can be adjusted to fit tightly against the bottom surface of the seat, thereby increasing the stabilizing effect of the limiting structure.
[0032] When people want to sit on the chair and watch the screen, they manually pull the handle 16 to drive the second support rod 3 to rotate 90 degrees toward one side of the seat 1. At the same time, the hinged rod 5, the connecting shaft 7 and the transmission mechanism drive the first fixed rod 6 to rotate 90 degrees relative to the second support rod 3 (in this process, if there is no transmission structure, the screen will be horizontal with the rotation of the second support rod 3. With the transmission structure, the first fixed rod 6 can rotate the screen 90 degrees to appear Figure 6), during this process, the first bevel gear 21 and the hinged rod 5 do not rotate, and then the second bevel gear 23 on the rotating shaft 22 meshing with the first bevel gear 21 rotates with the rotation of the second support rod 3, and then drives the first bevel gear 21 fixedly sleeved on the connecting shaft 7 to rotate, thereby rotating the first fixed rod 6 so that the screen faces the seat 1, making it convenient for the person sitting on the seat 1 to watch the content on the screen. When it is not necessary to watch, hold the handle 16 and apply force upward, and the second support rod 3 rotates 90 degrees in the opposite direction to an upright state. At this time, the hinged rod 5, the connecting shaft 7 and the transmission mechanism also drive the first fixed rod 6 to rotate 90 degrees in the opposite direction relative to the second support rod 3 to reset.
[0033] Example 2
[0034] The same points as those in Example 1 are not described in detail. The difference from Example 1 is that the transmission mechanism includes a disc 31, a connecting rod 32 and a second fixed rod 33. The connecting shaft 7 extends into one end of the second support rod 3 and the hinge rod 5 is fixed with a disc 31. The second fixed rod 33 is fixed to both of the discs 31. The two ends of the connecting rod 32 are rotatably connected to the second fixed rod 33. Figure 3 As shown, during the process of the second support rod 3 rotating 90 degrees toward one side of the seat 1, the hinged rod 5 and the disc 31 on the hinged rod 5 are fixed, and the connecting rod 32 connected to the two discs 31 drives the disc 31 fixed on the connecting shaft 7 to rotate in order to keep the distance unchanged, thereby realizing the rotation of the first fixed rod 6 relative to the second support rod 3, so that the screen faces the person on the seat 1.
[0035] In this embodiment, as the second support rod 3 rotates 90 degrees, the first fixed rod 6 also rotates 90 degrees driven by the transmission structure. This is achieved by controlling the diameter of the disc 31 and the distance from the second fixed rod 33 to the center of the disc 31 and the length of the second fixed rod 33. This is existing technology and will not be described in detail.
[0036] Example 3
[0037] On the basis of the above embodiment, the first support rod 2 can also adopt a telescopic structure, referring to Figure 7 The first support rod 2 includes an outer rod and an inner rod. The upper end of the inner rod is open and hollow. One end of the inner rod extends into the inner rod and the other end is hinged to the second support rod 3. The outer rod is provided with a plurality of plug-in holes 1 evenly arranged up and down, and the plug-in hole 1 passes through the side wall of the outer rod. The inner rod is provided with a plurality of plug-in holes 2 evenly arranged up and down, and the plug-in hole 2 passes through the side wall of the inner rod. The plug-in hole 1 and the plug-in hole 2 cooperate with each other to insert the pin shaft to realize the fixation of the outer rod and the inner rod. When the height needs to be adjusted, the pin shaft is pulled out, and the plug-in hole 1 and the plug-in hole 2 of the appropriate height are selected to cooperate with each other and then the pin shaft is inserted.
