Description

Technical Field

[0001] This invention belongs to the field of communication equipment technology, and more specifically, relates to a limit display device. Background Technology

[0002] As communication products continue to evolve, the same space capacity demands ever-increasing data exchange capacity, leading to continuous miniaturization of optical module packaging and continuous improvement in transmission rates. Simultaneously, various interactive information between the product and the operator is essential, such as indicator lights, silkscreen markings, company logos, board slot numbers, host chassis version and IP information, all requiring a certain amount of space. This interactive information is typically placed on the front of the product for easy identification; however, the space occupied significantly impacts the product's integration, potentially reducing the number of optical modules and altering their layout.

[0003] In current technical solutions, the following approaches address the relationship between displayed content and panel space: Solution 1: Use a small-width LCD screen placed on the front panel of the product to minimize usable space. Solution 2: Use fixed thin labels with static information printed on them, affixed to the top, sides, or handles of the product. Solution 3: Install the display screen on the mounting ears on both sides of the installation equipment, utilizing the space of the mounting ears for the display device. A comprehensive analysis of these solutions reveals varying degrees of drawbacks. Solution 1's display screen width reaches its limit after a certain point; considering the installation space, a width of 15mm becomes a bottleneck, making further reduction very difficult. Solution 2's adhesive labels can only carry static product information and cannot display real-time dynamic information. Solution 3's placement of the display screen on the mounting ears increases manufacturing complexity, causes inconvenience during on-site installation, and poses a risk of failure due to installation issues.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0051] Example 1:

[0052] This embodiment provides a limit display device, such as... Figure 1 and Figure 2 As shown, the device includes a movable component 1, a limiting component 2, and a display component 3, wherein:

[0053] The display component 3 is fixed inside the movable component 1, and the movable component 1 slides in cooperation with the limiting component 2.

[0054] The base plate 12 of the movable component 1 is provided with a guide groove 14, and the first limiting member 22 of the limiting component 2 is provided with a guide post 223. The guide post 223 is embedded in the guide groove 14 and slides along the guide groove 14. At the same time, the panel 13 of the movable component 1 is sleeved by the second limiting member 23 of the limiting component 2, and the base plate 12 of the movable component 1 is sleeved by the first limiting member 22. The movable component 1 moves in the space between the limiting component 2 and the inner wall of the chassis.

[0055] The movable component 1 includes a limiting groove 11, and the limiting component 2 includes a limiting rod 21. One end of the limiting rod 21 is embedded in the limiting groove 11, and the other end of the limiting rod 21 is fixed to the limiting component 2.

[0056] The limiting groove 11 is set on the back of the base plate 12 of the movable component 1. The limiting groove 11 fits against the inner wall of the chassis. The free end of the limiting rod 21 is embedded in the limiting groove 11 of the movable component 1. The fixed end of the limiting rod 21 is connected to the second flange 222 of the limiting component 2.

[0057] When the active component 1 drives the display component 3 to slide, the limiting rod 21 slides synchronously along the preset path of the limiting groove 11 in order to maintain the locked or unlocked state of the display device.

[0058] The display device is located near the inner wall of the chassis and uses a hidden pull-out design. Only the handle needs to be exposed to pull the display device out. With one pull, the display component 3 is fully exposed outside the chassis; with a second pull, the display component 3 retracts into the chassis, minimizing the space occupied on the chassis panel. This embodiment overcomes the limitations of display screen width and installation space, effectively reducing the valuable panel space occupied by the display screen. Furthermore, the display screen in the display component 3 can display both static and dynamic information, is easy to operate, and provides readily readable data.

[0059] In this first embodiment, in order to satisfy the locking and unlocking of the limiting rod 21 within the limiting groove 11, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 2 As shown, the limiting groove 11 includes a first groove 111, a second groove 112, and a third groove 113, wherein:

[0060] The two ends of the third groove 113 are respectively connected to the first groove 111 and the second groove 112, and one end of the third groove 113 is connected to a preset position in the middle of the first groove 111.

[0061] The preset position is between one-third and one-half of the first groove 111. In this embodiment, one-third is selected. A chamfer is set at the middle connection between the third groove 113 and the first groove 111.

[0062] In order to reduce the resistance of the limiting rod 21 when sliding from the second groove 112 to the third groove 113, when the third groove 113 is connected to the second groove 112, the end face of the third groove 113 is lower than the end face of the second groove 112.

[0063] To prevent the limiting rod 21 from falling into the third groove 113 when sliding from the first groove 111 to the second groove 112, when the third groove 113 is connected to the first groove 111, the end face of the third groove 113 is higher than the end face of the first groove 111.

[0064] The limiting rod 21 extends uphill from the end of the first groove 111 that is not connected to the second groove 112 and then embeds itself into the second groove 112, thus locking the movable component 1. The first groove 111 has a slope near the second groove 112.

[0065] The limiting rod 21, starting from the end of the first groove 111 not connected to the second groove 112, slopes up the first groove 111 and then embeds into the second groove 112, thus locking the movable component 1. After the limiting rod 21 is embedded in the limiting groove 11, the starting position is set at the end of the first groove 111 not connected to the second groove 112. After pulling the panel 13 of the movable component 1 once from the starting position, the limiting rod 21 slides from the first groove 111 into the second groove 112, and is locked within the second groove 112.

[0066] The limiting rod 21 falls into the third groove 113 along the second groove 112, and after sloping up the third groove 113, it falls into the middle of the first groove 111 and slides to the end of the first groove 111 that is not connected to the second groove 112, at which point the movable component 1 completes its reset. After the limiting rod 21 is in the locked state, the panel 13 of the movable component 1 is pulled out a second time. Under the action of the elastic element 24 pulling in the opposite direction, the limiting rod 21 falls into the third groove 113 along the second groove 112, and after sloping up the third groove 113, it falls into the middle of the first groove 111 and slides to the starting position, at which point the limiting rod 21 is released from its locked state. The third groove 113 has a slope in the middle.

[0067] In this first embodiment, in order to allow the limiting rod 21 to switch between locked and unlocked states within the second groove 112, a preferred implementation scheme exists in conjunction with this embodiment of the invention. Specifically, as follows: Figure 2 and Figure 3 As shown, the second groove 112 includes a first folded edge 1121, a second folded edge 114, a third folded edge 1122, a fourth folded edge 1124, and a fifth folded edge 1125, wherein:

[0068] The first folded edge 1121, the second folded edge 114, the third folded edge 1122, the fourth folded edge 1124, and the fifth folded edge 1125 are respectively located on both sides of the second groove 112.

[0069] The second folded edge 114 forms a first concave point 1126 and a first convex point 1127 with the first folded edge 1121 and the third folded edge 1122, respectively, and the fourth folded edge 1124 and the fifth folded edge 1125 form a second concave point 1128.

[0070] The limiting rod 21 slides into the second concave point 1128 along the first concave point 1126 and the first convex point 1127, and the limiting rod 21 is in a locked state.

[0071] like Figure 3 As shown, the left side of the second groove 112 includes a first folded edge 1121, a second folded edge 114 and a third folded edge 1122, and the right side of the second groove 113 includes a fourth folded edge 1124 and a fifth folded edge 1125.

[0072] The starting position is when the limiting rod 21 is at the end point of the first groove 111 that is not connected to the second groove 112. After the movable component 1 is pulled to the right once in the starting position, the limiting groove 11 is pulled to the right simultaneously. The limiting rod 21 first slides into the first concave point 1126 along the first folded edge 1121 on the left side of the second groove 112. The limiting groove 11 stops sliding under the pulling action outside the chassis. If the pulling action to the movable component 1 is stopped at this time, the limiting groove 11 slides to the left under the stretching action of the elastic member 24. Therefore, the limiting rod 21 slides out in the first concave point 1126. After passing the first convex point 1127, the limiting rod 21 falls into the second concave point 1128. At this time, the elastic member 24 can no longer pull the limiting groove 11 to the left. The limiting rod 21 and the movable component 1 are in a locked state.

[0073] If the limiting rod 21 slides into the third groove 113 along the fourth fold 1124 in the second concave point 1128, the limiting rod 21 is unlocked.

[0074] like Figure 3 As shown, the limiting rod 21 falls into the second concave point 1128. After the limiting rod 21 and the movable component 1 are in the locked state, the movable component 1 is pulled to the right a second time from outside the chassis. The limiting groove 11 slides to the right, and the limiting rod 21 slides down from the second concave point 1128 and falls into the third groove 113.

[0075] To prevent the limiting rod 21 from falling directly into the third groove 113 along the first fold 1121, a second convex point 1129 is formed at the intersection of the fifth fold 1125 and the first groove 111, and the convex point 1129 is oriented in a direction perpendicular to the first fold 1121.

[0076] To prevent the limiting rod 21 from falling directly into the third groove 113 along the second fold 114, the direction of the second fold 114 is inclined toward the third groove 113, and the protrusion of the first convex point 1127 is oriented in a direction perpendicular to the fifth fold 1125.

[0077] A chamfer is provided at the connection between the fourth fold 1124 and the third groove 113, which makes the process of the limiting rod 21 falling from the second groove 112 into the third groove 113 smoother and reduces the resistance during the groove transformation process.

[0078] In order to embed the display component 3 within the movable component 1, so that the display component 3 is exposed or hidden within the chassis when the movable component 1 is pulled out, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 4 and Figure 5 As shown, the active component 1 includes a base plate 12 and a panel 13, wherein:

[0079] The base plate 12 is provided with an area to accommodate the display component 3, and the panel 13 is provided with a window 131. The display component 3 is fixed between the base plate 12 and the panel 13, and the window 131 is used to display content and / or connect to the outside.

[0080] like Figure 6 As shown, a concave groove 122 is provided on the surface of the base plate 12. After the flexible strip 31 and the display screen 32 are embedded in the concave groove 122, the flexible strip 31 and the display screen 32 are on the same plane as the base plate 12. The window 131 can display the content displayed on the display screen 32, and can also be electrically connected to the flexible strip through the window 131.

[0081] like Figure 4 As shown, panel 13 is also equipped with button 132. Considering the limited information capacity of display screen 32, panel 13 can be electrically connected to base plate 12. By pressing button 132, the screen flipping function of display screen 32 can be completed, realizing multi-screen display, which can significantly improve the information capacity of display screen 32. The handle end of base plate 12 is attached to button 132 of panel 13, which facilitates pressing button 132 and pulling base plate 12.

[0082] In this first embodiment, in order to limit the active areas of the base plate 12 and the panel 13 respectively, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 7 As shown, the limiting component 2 further includes a first limiting member 22 and a second limiting member 23, wherein:

[0083] The first limiting member 22 and the second limiting member 23 are respectively sleeved on the base plate 12 and the panel 13 of the movable component 1, and the central axes of the first limiting member 22 and the second limiting member 23 are located on the same connecting line.

[0084] The first limiting member 22 and the second limiting member 23 are respectively fixed to the inner wall of the chassis;

[0085] The movable component 1 slides in the space formed by the first limiting member 22, the second limiting member 23, and the inner wall of the chassis.

[0086] In this first embodiment, in order to limit the sliding stroke of the base plate 12, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 2 As shown, the first limiting member 22 includes a first flange 221, a second flange 222, and a guide post 223, wherein:

[0087] The first flange 221 and the second flange 222 are respectively disposed on both sides of the first limiting member 22, and the first flange 221 and the second flange 222 are sleeved on the bottom plate 12, and the first flange 221 and the second flange 222 are respectively fixed to the inner wall of the chassis;

[0088] The base plate 12 and the panel 13 are provided with a guide groove 14 at the same position. The guide groove 14 passes through the base plate 12 and the panel 13. The guide post 223 is embedded in the guide groove 14. When the base plate 12 and the panel 13 slide, the guide post 223 is driven to slide synchronously along the guide groove 14.

[0089] When the fixed end of the limiting rod 21 is located at the second flange 222, and the free end of the limiting rod 21 is located at the end point of the first groove 111 that is not connected to the second groove 112, the fixed post 122 and the two ends of the limiting rod 21 are on the same straight line.

[0090] In this first embodiment, in order to fix the display component 3 and reduce its space occupation, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 6 As shown, the display component 3 includes a flexible strip 31 and a display screen 32, which are electrically connected. A recessed groove 122 is provided on the surface of the base plate 12. After the flexible strip 31 and the display screen 32 are embedded in the recessed groove 122, they are on the same plane as the base plate 12. The flexible strip 31 and the display screen 32 are fixed to the recessed groove 122 of the base plate 12 by adhesive bonding.

[0091] In this first embodiment, to facilitate the stretching and contraction of the flexible strip 31, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 6 As shown, a reinforcing film is attached to the back of the soft strip 31 to enhance its rigidity. The reinforcing film is made of PC film.

[0092] In this first embodiment, to facilitate the stretching and contraction of the flexible strip 31, in conjunction with the embodiments of the present invention, there is also a preferred implementation scheme, specifically, as follows: Figure 7As shown, the device also includes a guide plate 4, which is fixed to the inner wall of the chassis, and the soft strip 31 is accommodated in the gap between the guide plate 4 and the inner wall of the chassis. The soft strip 31 is electrically connected to the back panel of the chassis, and the guide plate 4 facilitates the extension and retraction of the soft strip 31.

[0093] The guide plate 4 can be fixed to the inner wall of the chassis by adhesive or screws. In this embodiment, screws are used. After the guide plate 4 is fixed to the inner wall of the chassis, it forms a space to accommodate the flexible strip 31, which can extend and retract along the direction of the guide plate 4.

[0094] Example 2:

[0095] This second embodiment provides a method for using the limit display device from the first embodiment. For ease of description, the limit display device is fixed to the inner wall of the chassis, as shown below. Figure 2 As shown, after the limiting rod 21 is inserted into the limiting groove 11, the starting position of the limiting display device is set at the end of the first groove 111 that is not connected to the second groove 112. At the starting position, the main body of the limiting display device is hidden inside the chassis, and only a small part of the panel 13 of the movable component 1 is exposed in the chassis as a handle.

[0096] When the operator needs to view the display data of the limit display device, he only needs to pull the panel 13 of the movable component 1 outward for the first time. The limit rod 21 slides from the first groove 111 into the second groove 112 and is locked in the second groove 112.

[0097] After the limit rod 21 is locked, if the operator no longer needs to view the display data of the limit display device, they only need to pull the panel 13 of the movable component 1 a second time. Under the action of the elastic element 24 pulling in the opposite direction, the limit rod 21 falls into the third groove 113 along the second groove 112, and after going uphill along the third groove 113, it falls into the middle of the first groove 111 and slides to the starting position. The limit rod 21 is then released from the locked state, and the limit display device is hidden back inside the chassis.

[0098] like Figure 3 As shown, the left side of the second groove 112 includes a first folded edge 1121, a second folded edge 114 and a third folded edge 1122, and the right side of the second groove 113 includes a fourth folded edge 1124 and a fifth folded edge 1125.

[0099] The starting position is when the limiting rod 21 is at the end point of the first groove 111 that is not connected to the second groove 112. After the panel 13 of the movable component 1 is pulled to the right for the first time in the starting position, the limiting groove 11 is pulled to the right simultaneously. The limiting rod 21 first slides into the first concave point 1126 along the first folded edge 1121 on the left side of the second groove 112. The limiting groove 11 stops sliding under the pulling action outside the chassis. If the pulling action to the movable component 1 is stopped at this time, the limiting groove 11 slides to the left under the stretching action of the elastic member 24. Therefore, the limiting rod 21 slides out in the first concave point 1126. After passing the first convex point 1127, the limiting rod 21 falls into the second concave point 1128. At this time, the elastic member 24 can no longer pull the limiting groove 11 to the left. The limiting rod 21 and the movable component 1 are in a locked state.

[0100] If the limiting rod 21 slides down the fourth fold 1124 into the third groove 113 in the second concave point 1128, and the limiting rod 21 falls into the second concave point 1128, and the limiting rod 21 and the movable component 1 are in a locked state, the panel 13 of the movable component 1 is pulled to the right for the second time from outside the chassis, the limiting groove 11 slides to the right, and the limiting rod 21 slides down from the second concave point 1128 into the third groove 113, and the limiting rod 21 returns to the starting position.

[0101] The usage method of the limit display device provided in this embodiment can break through the width space limit of the display screen and installation, effectively reduce the valuable panel space occupied by the width of the display screen, and is easy to operate and read. It is worth promoting.

[0102] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
