[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a protective touch panel, including an assembly box, a curtain, a touch panel, a guide rail, a first rotating shaft, and a support chain. The touch panel is installed inside the assembly box, and guide rails are installed on both inner walls of the assembly box. The first rotating shaft and the second rotating shaft are installed inside the upper end of the assembly box. The outer wall of the first rotating shaft is wound with an equidistantly distributed support chain, and the outer surface of the second rotating shaft is wound with a curtain located in front of the support chain and whose lower end is connected to the lower end of the support chain. The support chain includes equidistantly distributed chain blocks, symmetrically distributed and rotatably installed assembly holes and shaft blocks at both ends of the chain blocks, and a slot is opened at the front end of each chain block. A locking block is provided at the front end of each chain block, and one end of the support chain fits against the inner wall of the slot after being unfolded.

[0008] Furthermore, a storage box is provided inside the upper end of the assembly box, and the upper and lower ends of the storage box are open. Both the first rotating shaft and the second rotating shaft are rotatably installed inside the storage box.

[0009] Specifically, the storage box stores the support chain and curtain of the roll-up mechanism, making the protective structure look neat after roll-up.

[0010] Furthermore, both ends of the rotating shaft one are wound with a coil spring two whose outer end is connected to the storage box, and both ends of the rotating shaft two are provided with a coil spring one whose outer end is connected to the storage box. The rotating shaft one is located directly below the rotating shaft two.

[0011] Specifically, when the first rotating shaft rotates to release the support chain, it compresses the first disc spring, which then tightens to apply an elastic force to the support chain. When the second rotating shaft rotates to release the curtain, it compresses the second disc spring, which then tightens to apply an elastic force to the curtain.

[0012] Furthermore, a handle is provided on the front side of the lower end of the curtain, a sliding groove is provided inside the guide rail, and sliders that are slidably installed inside the sliding groove are provided on both sides of the lower end of the curtain, and the upper end of the guide rail is closed.

[0013] Specifically, the handle makes it easy to apply pulling force to the curtain. When the curtain is released, the slider slides in the groove inside the guide rail, which constrains the lower end of the curtain, so that the lower end of the curtain is guided to slide longitudinally.

[0014] Furthermore, a rectangular tube communicating with the slide groove is provided at one end of the guide rail, and a valve block located inside the slide groove is provided at the opening of the rectangular tube. The upper end of the valve block is provided with an inclined surface, and the lower end of the valve block is flat.

[0015] Specifically, the rectangular tube is used for the installation of the valve block with elastic support. When the slider descends and squeezes the upper end of the valve block through the inclined surface, it passes through the valve block through the upper inclined surface. When it has completely passed through the valve block, the lower end of the valve block intercepts the slider horizontally. The unfolded curtain is positioned by the slider.

[0016] Furthermore, a guide plate is provided inside the rectangular tube, and a guide rod connected to the valve block is slidably installed inside the guide plate. A limit ring is sleeved on the outer wall of the guide rod, and a spring sleeved on the outside of the guide rod is provided between the limit ring and the guide plate. A pull rod located on the outside of the rectangular tube is provided at one end of the guide rod.

[0017] Specifically, the guide plate provides sliding support for the guide rod, and the elastic force of the spring acts on the guide rod through the limiting ring, so that the valve block is elastically supported, and the gripping rod makes it easy to apply a pulling force to the guide rod.

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention introduces multiple sets of rotating support chains in conjunction with a flexible, rollable curtain to shield the front of the touch panel. When the support chains are unfolded, they are vertical. Limiting blocks on the support chains prevent the vertical support chains from rotating in the opposite direction. The support curtain supports the rear end of the curtain. When an impact force is applied to the front of the touch panel, it is intercepted by the multiple sets of support chains, preventing direct contact with the touch panel. When the touch panel is in use, the locking blocks do not constrain the chain blocks to rotate inward, allowing the chain blocks and the curtain to be effectively rolled up above the touch panel, avoiding interference with the touch panel. Furthermore, it reduces space occupation during use, making it aesthetically pleasing and convenient to use.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Please see Figure 1-6As shown, this embodiment is a protective touch panel, including an assembly box 1, a curtain 2, a touch panel 3, a guide rail 4, a pivot 7, and a support chain 11. The touch panel 3 is installed inside the assembly box 1. Guide rails 4 are installed on both inner walls of the assembly box 1. A pivot 7 and a pivot 8 are installed inside the upper end of the assembly box 1. The support chain 11 is wound up on the outer wall of the pivot 7. The curtain 2 is located in front of the support chain 11 and its lower end is connected to the lower end of the support chain 11. The support chain 11 includes chain blocks 12 that are equidistantly distributed, assembly holes 13 that are symmetrically distributed at both ends of the chain blocks 12 and rotatably installed, and shaft blocks 14. Each chain block 12 has a slot 16 at its front end. Each chain block 12 has a locking block 15 at its front end, which is attached to the inner wall of the slot 16 after the support chain 11 is unfolded.

[0037] The upper part of the assembly box 1 is equipped with a storage box 5. The upper and lower parts of the storage box 5 are open. The first rotating shaft 7 and the second rotating shaft 8 are rotatably installed inside the storage box 5.

[0038] Both ends of the rotating shaft 7 are wound with a coil spring 10 whose outer end is connected to the storage box 5. Both ends of the rotating shaft 8 are equipped with a coil spring 9 whose outer end is connected to the storage box 5. The rotating shaft 7 is located directly below the rotating shaft 8.

[0039] A handle 25 is provided on the front side of the lower end of the curtain 2. A groove 24 is provided inside the guide rail 4. Sliding sliders 23 are provided on both sides of the lower end of the curtain 2 and are slidably installed inside the groove 24. The upper end of the guide rail 4 is closed.

[0040] One end of the guide rail 4 is provided with a rectangular tube 6 that communicates with the slide groove 24. A valve block 21 located inside the slide groove 24 is provided at the opening of the rectangular tube 6. The upper end of the valve block 21 is provided with an inclined surface, and the lower end of the valve block 21 is flat.

[0041] A guide plate 18 is provided inside the rectangular tube 6. A guide rod 22, one end of which is connected to the valve block 21, is slidably installed inside the guide plate 18. A limit ring 20 is sleeved on the outer wall of the guide rod 22. A spring 19 is sleeved on the outside of the guide rod 22 between the limit ring 20 and the guide plate 18. A pull rod 17 located on the outside of the rectangular tube 6 is provided at one end of the guide rod 22.

[0042] In this embodiment, the operator holds the handle 25 at the lower end of the curtain 2 and pulls it vertically downwards. The curtain 2 slides along the groove 24 inside the guide rail 4 via the slider 23, which drives the rotating shaft 8 to rotate and release the curtain 2. At the same time, the rotating shaft 7 rotates synchronously to unfold the support chain 11. When the slider 23 moves to the end of the guide rail 4, it squeezes the inclined surface at the upper end of the valve block 21. After the valve block 21 is compressed, it retracts into the rectangular tube 6. After the slider 23 passes, the valve block 21 is reset under the action of the spring 19. Its lower end plane forms a mechanical limit with the slider 23, thus completing the positioning of the curtain 2.

[0043] When the support chain 11 is unfolded, the locking block 15 of the adjacent chain block 12 is locked into the slot 16 to form a rigid vertical structure. Multiple sets of support chains 11 and curtain 2 form a protective barrier to prevent external objects from directly hitting the touch panel 3.

[0044] Pull the lever 17 outwards, and the guide rod 22 will cause the valve block 21 to disengage from the slide groove 24. At this time, the curtain 2 loses its lower end constraint. The elastic force of the first disc spring 9 and the second disc spring 10 drives the first shaft 7 and the second shaft 8 to rotate in opposite directions. The support chain 11 and the curtain 2 are rolled up into the storage box 5 in sync, and the touch panel 3 is fully exposed. The user can touch the panel directly with their finger or stylus. After the support chain 11 is fully retracted, it is flush with the edge of the panel and does not occupy the operating space.

[0045] When an external object collides with the curtain 2, the impact force is dispersed through the flexible curtain 2 to multiple sets of support chains 11. Each support chain 11 is hinged by a chain block 12 through a mounting hole 13 and a shaft block 14. In the unfolded state, the locking block 15 engages with the locking groove 16 to prevent the chain block 12 from rotating toward the touch panel 3, forming an inflexible rigid support structure. The multiple sets of support chains 11 are distributed in a fence-like manner, which converts the concentrated impact into a component force along the axial direction of the chain block 12. Combined with the deformation absorption of the curtain 2, the impact energy is dissipated, ensuring that the touch panel 3 body is not subjected to force.

[0046] Compared to traditional protective covers, this device reduces space usage by 7% after rewinding, making it suitable for narrow industrial control cabinets. Traditional covers require additional swing space to open and close, and are prone to interference with surrounding equipment. This device, however, is flush with the panel after rewinding, eliminating conflicts with operating space and achieving a balance between protective function and ease of operation. It is especially suitable for industrial scenarios with stringent requirements for space utilization and continuous operation, such as CNC machine tools and automated production lines.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
