Technical Field
[0001] This utility model relates to the field of screen support technology, specifically an adjustable screen support. Background Technology
[0002] With the widespread use of electronic devices, screens, as crucial components for human-computer interaction, are facing increasingly stringent manufacturing requirements. During screen assembly, the inner and outer screens typically need to be precisely aligned and pressed together to ensure optimal display quality and touch sensitivity. Screen pressing brackets, as auxiliary equipment, are used to fix and position screen components; their structural design and adjustability directly affect pressing accuracy and yield rate.
[0003] The existing screen pressing process typically places the inner screen in a specific mold support, and then places the mold support in the screen pressing equipment. Although this method is convenient, it requires changing the mold, is difficult to adjust according to the size of the inner screen, and directly placing the inner screen inside the mold support leaves a small gap between the inner screen and the mold support. This can cause slight misalignment between the inner and outer screens when the pressing block presses the outer screen, thus affecting the pressing quality. Therefore, an adjustable screen pressing support is needed to solve the shortcomings of the existing method. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing screen holders, which are difficult to flexibly fix according to the size of the inner screen.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable screen support bracket, comprising a support frame, a fixing block fixedly connected to the inner side of the support frame, and a support plate fixedly connected to the top of the fixing block, a workpiece disposed at the top of the support plate, several clamping blocks I disposed on the long side of the support plate, and the clamping blocks I being arranged in a linear array, a set of symmetrical control components movably connected to the inner side of the support frame, and the control components being fixedly connected to the clamping blocks I, several clamping blocks II disposed on the short side of the support plate, and the clamping blocks II being arranged in a linear array, an adjustment component disposed on the inner side of the support frame, and the adjustment component being fixedly connected to the clamping blocks II, the clamping blocks I being in contact with the long side of the workpiece, and the clamping blocks II being in contact with the short side of the workpiece.
[0006] Furthermore, the control component includes a connecting plate, a connecting rod, a first collar, a second collar, and a guide post. The guide post passes through the first collar and the second collar, and is movably connected to both the first collar and the second collar. The outer sides of the first collar and the second collar are movably connected to the connecting rod via a pivot, and the other end of each connecting rod is movably connected to one side of the connecting plate via a pivot. The other side of the connecting plate is fixedly connected to the end of the clamping block.
[0007] Furthermore, the control assembly also includes a folding spring and a push rod. The folding spring is fixedly connected to the inside of the guide post, and the free end of the folding spring is fixedly connected to one side of the collar. The push rod is movably connected to the inside of the guide post, and one end of the push rod is in contact with the other side of the collar.
[0008] Furthermore, a set of symmetrical guide posts are fixedly connected to the back side of the connecting plate one. The other end of the guide post is movably connected to a fixed cylinder, and the other end of the fixed cylinder is fixedly connected to the inner side of the support frame. A return spring is sleeved on the outer side of the guide post. One end of the return spring is fixedly connected to the back side of the connecting plate one, and the other end of the return spring is fixedly connected to the inner side of the support frame.
[0009] Furthermore, the pallet has multiple sets of symmetrical guide grooves, each located on the long side of the pallet, and each clamping block is slidably connected to the guide groove. One end of the push rod extends to the outside of the support frame, and the end of the push rod is fixedly connected to a push bar.
[0010] Furthermore, the adjustment assembly includes a gear, a rack, a compression spring, and an adjustment rod. The gear is movably connected to the inside of the support frame via a rotating shaft. The racks are symmetrically arranged with the rotation axis of the gear as the origin, and each rack meshes with the gear. The compression spring is fixedly connected to one end of the rack, and the other end of the compression spring is fixedly connected to the inside of the support frame. The adjustment rod is fixedly connected to the end of another rack, and the other end of the adjustment rod extends to the outside of the support frame.
[0011] Furthermore, the adjustment assembly also includes a second connecting plate, which is symmetrically arranged and fixedly connected to the end of the second clamping block. The support plate has multiple sets of symmetrical guide grooves, and the second clamping block is slidably connected to the guide grooves.
[0012] Furthermore, the ends of the rack are fixedly connected to the bottom of the connecting plate two, and one end of the adjusting rod is fixedly connected to the push bar two.
[0013] Compared with existing technologies, this adjustable screen holder has the following advantages:
[0014] 1. This utility model uses push strip one and push strip two. By pressing push strip one and push strip two simultaneously, the inner screen can be easily placed on the tray. Then, the outer screen to be pressed is placed on top of the inner screen. When push strip one and push strip two are released, clamping block one automatically fits into the long side of the inner screen and the outer screen, and clamping block two automatically fits into the long side of the inner screen and the outer screen, so that the outer screen and the inner screen are aligned. At the same time, it is convenient to correct the inner screen and the outer screen to the middle position of the tray, which is conducive to the pressure block applying even pressure to the outer screen.
[0015] 2. This utility model has two clamping blocks: clamping block one fits against the long side of the screen, and clamping block two fits against the short side of the screen. This makes it easier to adapt to the clamping of screens of different sizes. The top of each clamping block is constructed with a slope. When the pressure block moves downward, the pressure block abuts against the top slope of the clamping block, so that the clamping block can automatically move away from the screen and the clamping block will not affect the screen pressing operation.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] like Figure 1-4As shown, this utility model provides a technical solution: an adjustable screen pressing bracket, including a support frame 1, a fixing block 2 fixedly connected to the inner side of the support frame 1, and a support plate 3 fixedly connected to the top of the fixing block 2. A workpiece 4 is provided at the top of the support plate 3. In this embodiment, the workpiece 4 includes an inner screen and an outer screen, with the outer screen located on top of the inner screen. The outer screen is pressed onto the top of the inner screen by a screen pressing device. Several clamping blocks 5 are provided on the long side of the support plate 3, and the clamping blocks 5 are arranged in a linear array. A set of symmetrical control components 6 are movably connected to the inner side of the support frame 1 to control... Component 6 is fixedly connected to clamping block 5. Several clamping blocks 7 are provided on the short side of the support plate 3. The clamping blocks 7 are arranged in a linear array. An adjustment component 8 is provided on the inner side of the support frame 1. The adjustment component 8 is fixedly connected to clamping block 7. Clamping block 5 is in contact with the long side of the workpiece 4, and clamping block 7 is in contact with the short side of the workpiece 4. The top of clamping block 5 and the top of clamping block 7 are both provided with inclined surfaces. When the screen is pressed down, clamping block 5 and clamping block 7 can move away from the screen. In this embodiment, there are nine clamping blocks 5 and four clamping blocks 7.
[0023] like Figure 1 and Figure 3 As shown, the control component 6 includes a connecting plate 601, a connecting rod 602, a first collar 603, a second collar 604, and a guide post 605. The guide post 605 passes through the first collar 603 and the second collar 604, and is movably connected to both the first collar 603 and the second collar 604. The outer sides of the first collar 603 and the second collar 604 are movably connected to the connecting rod 602 via a pivot. The other end of the connecting rod 602 is movably connected to one side of the connecting plate 601 via a pivot. The other side of the connecting plate 601 is fixedly connected to the end of the clamping block 5. The control component 6 also includes a folding spring 606 and a push rod 607. The folding spring 606 is fixedly connected inside the guide post 605. The free end of 6 is fixedly connected to one side of collar 603. Push rod 607 is movably connected to the inside of guide post 605. One end of push rod 607 is in contact with the other side of collar 603. Collar 603 and collar 604 are symmetrically distributed. Collar 603 and collar 604 move with connecting rod 602. A set of symmetrical guide posts 9 are fixedly connected to the back side of connecting plate 601. The other end of guide post 9 is movably connected to fixed cylinder 10. The other end of fixed cylinder 10 is fixedly connected to the inner side of support frame 1. A return spring 11 is sleeved on the outer side of guide post 9. One end of return spring 11 is fixedly connected to the back side of connecting plate 601. The other end of return spring 11 is fixedly connected to the inner side of support frame 1.
[0024] like Figure 1 and Figure 2As shown, the pallet 3 has multiple sets of symmetrical guide grooves 12. The guide grooves 12 are located on the long side of the pallet 3, and the clamping blocks 5 are slidably connected to the guide grooves 12. One end of the push rod 607 extends to the outside of the support frame 1, and the end of the push rod 607 is fixedly connected to the push bar 13.
[0025] The push bar 13 can control the movement of the clamping block 5 along the guide groove 12, thereby making the clamping blocks 5 on opposite sides move away from each other, providing lateral space above the pallet 3, so that the workpiece 4 can be located on the opposite side of the clamping block 5.
[0026] like Figure 1 and Figure 4 As shown, the adjusting assembly 8 includes a gear 801, a rack 802, a compression spring 803, and an adjusting rod 804. The gear 801 is movably connected to the inside of the support frame 1 via a rotating shaft. The racks 802 are symmetrically arranged about the rotating shaft of the gear 801, and each rack 802 meshes with the gear 801. The compression spring 803 is fixedly connected to one end of the rack 802, and the other end of the compression spring 803 is fixedly connected to the inside of the support frame 1. The adjusting rod 804 is fixedly connected to the other rack 802. The adjustment assembly 8 also includes a connecting plate 805, which is symmetrically arranged and fixedly connected to the end of the clamping block 7. The support plate 3 has multiple sets of symmetrical guide grooves 14, and the clamping block 7 is slidably connected to the guide grooves 14 respectively. The ends of the rack 802 are fixedly connected to the bottom of the connecting plate 805 respectively. The adjustment rod 804 is fixedly connected to the push bar 15 at one end of the rack 802.
[0027] The push bar 2 15 can control the movement of the clamping block 2 7 along the guide groove 2 14, thereby making the clamping blocks 2 7 on opposite sides move away from each other, providing longitudinal space above the pallet 3, so that the workpiece 4 can be located on the opposite side of the clamping block 2 7.
[0028] Simultaneously press push strip 13 and push strip 2 15 to facilitate placing the inner screen on top of the tray 3. Then, place the outer screen to be pressed on top of the inner screen. Release push strip 13 and push strip 2 15, and clamp block 1 5 will automatically fit against the long sides of the inner and outer screens, and clamp block 2 7 will automatically fit against the long sides of the inner and outer screens, aligning the outer and inner screens. This also facilitates the simultaneous correction of the inner and outer screens to the center position of the tray 3, which is beneficial for the pressing blocks to apply pressure evenly to the outer screen.
[0029] Working principle: In use, firstly, pusher bar 13 and pusher bar 2 15 are pushed inward simultaneously. Pusher bar 13 controls the two push rods 607 to move inward synchronously. Push rods 607 move along the inside of guide post 605, pushing collar 1 603 to move along guide post 605, causing folding spring 606 to compress and shorten. The movement of collar 1 603 drives connecting rod 602 to rotate synchronously, causing connecting plate 1 601 to move towards guide post 605. Since guide post 9 moves along the axis of fixed cylinder 10, connecting plate 1 601 squeezes return spring 11. Connecting plate 1 601 causes the other connecting rod 602 to rotate, pushing collar 2 604 to move along guide post 605. That is, collar 1 603 and collar 2 604 move away from each other. Connecting plate 1 601 drives clamping block 1 5 to move synchronously along guide groove 12, that is, clamping block 1 5 moves away from each other. Pusher bar 2 15 controls adjusting rod 804 in the support frame. The internal movement of the support frame 1 causes the adjusting rod 804 to move one of the racks 802, causing the gear 801 to rotate, which in turn causes the other rack 802 to move in the opposite direction. The rack 802 drives the connecting plate 805 on the same side to move synchronously, thereby controlling the clamping blocks 7 on opposite sides to move away from each other along the guide groove 14. Then, the workpiece 4 is placed on the support plate 3, and then the push bar 13 and push bar 15 are released. The clamping block 15 moves along the guide groove 12 until the clamping block 15 is in contact with the long side of the workpiece 4, and the clamping block 7 moves along the guide groove 14 until the clamping block 7 is in contact with the short side of the workpiece 4, so that the position of the workpiece 4 is automatically corrected. Then, the support frame 1 is placed in the screen pressing device. The pressing block of the screen pressing device moves downward, and the pressing block abuts against the top inclined surface of the clamping block 15 and the top inclined surface of the clamping block 7, so that the clamping blocks 15 and 27 move away from the workpiece 4, thereby pressing the outer screen of the workpiece 4 onto the top of the inner screen.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
