Description

Technical Field

[0001] This utility model belongs to the field of display technology, and in particular relates to a display cover and a liquid crystal display. Background Technology

[0002] Existing LCD monitors typically have a cover plate on the outside of the screen, assembled with a back panel to protect the display. The cover plate has a shielding layer at its edge to block the peripheral circuitry and mounting structure of the LCD monitor. Usually, after the cover plate and the back panel are inserted together, they are further secured with bolts. This means that when disassembling, after the user unscrews the bolts, they need to use a screwdriver or other tools to pry the back panel off the cover plate. This method can easily damage the screen and other electronic components inside the monitor. This paper proposes a monitor cover plate that is easy to disassemble. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a display cover and a liquid crystal display, solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a display cover and a liquid crystal display, including a back cover, and further including: a cover plate, a sliding cylinder, and a guide rod; two of the sliding cylinders are symmetrically slidably connected to the guide rod, the guide rod is fixedly connected to the cavities on both sides of the cover plate, and the cover plate and the back cover are detachably fixedly connected by multiple bolts.

[0005] Beneficial effects

[0006] This utility model provides a display cover and a liquid crystal display, which have the following advantages compared with the prior art:

[0007] 1. When the back cover needs to be removed, the user places the cover face down on the workbench and uses an Allen wrench to remove the bolts on the back cover one by one. Then, the Allen wrench is placed on the rotary head, and the rotary head is started to rotate at a constant speed. At this time, the left-hand and right-hand lead screws, which are fixed to each other, begin to rotate synchronously, driving the slide cylinder connected to them to begin linear movement along the connection between the slide cylinder and the guide rod. At this time, the slide cylinder, through the push rod hinged to it, begins to push the abutment plate. At the same time, the two push rods are symmetrically arranged on the abutment plate, so that the abutment plate can slide smoothly, thereby making the buffer fixed on the abutment plate... The cushioning pad gradually comes into contact with the back cover. Once the cushioning pad is in contact with the back cover, continuing to rotate the head will apply a pushing force to the back cover through the abutment plate, causing the back cover to gradually separate from the cover plate. At the same time, since both the back cover and the cover plate are made of materials with high hardness, deformation on both sides can be effectively prevented, thus allowing the cover plate to separate from the back cover as a whole. During this process, the two rubber heads are always pressed against the back cover under the action of the spring force, so that the two rubber heads cooperate to limit the back cover, preventing the user from accidentally touching the back cover after it is removed, causing the back cover to fall to the ground and break.

[0008] 2. When the user needs to remove the back cover, press the pressure blocks on both sides or any one side to make the pressure blocks slide in the slide frame, thereby driving the connecting block fixedly connected to it. This causes the connecting block to compress the spring fixedly connected to it and begin to slide into the back plate. At this time, the rubber head stops contacting the back cover, and the user can then remove the back cover and rotate the rotating head to reset the back plate, avoiding affecting the user's maintenance.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1-4 The present invention provides a display cover and a liquid crystal display, including a back cover 101, and further including: a cover plate 201, a slide cylinder 202, and a guide rod 203; two slide cylinders 202 are symmetrically slidably connected to the guide rod 203, the guide rod 203 is fixedly connected to the cavities on both sides of the cover plate 201, and the cover plate 201 and the back cover 101 are detachably fixedly connected by a plurality of bolts.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific back cover 101 and cover plate 201 described in the above embodiments. For example, the back cover 101 and cover plate 201 are made of plastic material with greater hardness or metal plate. The purpose of this arrangement is to prevent deformation when the back cover 101 is subjected to force on both sides, so that the back cover 101 can be separated from the cover plate 201 as a whole.

[0018] Specifically, push rods 204 are hinged to the two slide cylinders 202 respectively, and the other end of the push rods 204 is hinged to the abutment plate 205. A buffer pad 206 is fixedly connected to the abutment plate 205.

[0019] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific push rod 204 described in the above embodiments. For example, the push rod 204 should be made of a high-hardness material, and its two ends should be further hardened and reinforced. The purpose of this setting is to prevent it from breaking under stress.

[0020] Specifically, the buffer pad 206 contacts the back cover 101, and the area on the back cover 101 directly opposite the buffer pad 206 is a thickened plate, and no electronic components are installed on it. That is, the buffer pad 206 only contacts the thickened plate on the back cover 101 at the corresponding location.

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific back cover 101 and cover plate 201 described in the above embodiments. For example, both sides of the back cover 101 and cover plate 201 are provided with cavities for accommodating the mechanical components in this application. The purpose of this arrangement is to avoid damage to electronic components such as the display screen.

[0022] Specifically, the two slide cylinders 202 are respectively threaded onto the left-hand lead screw 207 and the right-hand lead screw 208. The left-hand lead screw 207 and the right-hand lead screw 208 are fixedly connected, and the left-hand lead screw 207 is rotatably connected to the cover plate 201.

[0023] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific left-hand lead screw 207 and right-hand lead screw 208 described in the above embodiments. For example, both the left-hand lead screw 207 and the right-hand lead screw 208 are selected as lead screws with self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect of the slider connected to the thread on it.

[0024] Specifically, a rotating head 209 is fixedly connected to the right-hand screw 208. The rotating head 209 is rotatably connected in the groove of the cover plate 201. The user should rotate the rotating head 209 using an Allen wrench.

[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific rotating head 209 described in the above embodiments. For example, the rotating head 209 can be replaced with a micro motor, and the micro motor is fixedly connected to the cover plate 201, and its output shaft is fixedly connected to the right-hand lead screw 208 for driving the right-hand lead screw 208 to rotate at a constant speed.

[0026] Specifically, limiting rods 301 are symmetrically fixedly connected to both sides of the abutment plate 205. A connecting block 303 is slidably connected to the limiting rod 301. A rubber head 304 is fixedly connected to the connecting block 303. The two rubber heads 304 are pressed against the rear cover 101.

[0027] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific rubber head 304 described in the above embodiments. For example, the rubber head 304 should be a rubber tube with anti-slip effect. The purpose of this setting is to facilitate the increase of the stability of the two rubber heads 304 in limiting the back cover 101.

[0028] Specifically, a spring 302 is sleeved on the limiting rod 301. One end of the spring 302 is fixedly connected to the abutment plate 205, and the other end of the spring 302 is fixedly connected to the connecting block 303.

[0029] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific spring 302 described in the above embodiments. For example, the spring 302 can be replaced with other forms of elastic components, such as air cushions. The purpose of this arrangement is to avoid deformation of the spring after long-term use, which would prevent the rubber head 304 from being pushed against the back cover 101.

[0030] Specifically, the abutment plate 205 is provided with symmetrical sliding frames 305 on both sides, and a pressure block 306 is slidably connected inside the sliding frame 305. The pressure block (306) is fixedly connected to the connecting block (303).

[0031] In this embodiment of the utility model, when it is necessary to remove the rear cover 101, the user places the cover plate 201 face down on the workbench and removes the bolts on the rear cover 101 one by one using an Allen wrench. Then, the Allen wrench is placed on the rotating head 209, and the rotating head 209 is made to rotate at a constant speed. At this time, the left-hand lead screw 207 and the right-hand lead screw 208, which are fixedly connected to each other, begin to rotate synchronously, driving the slide cylinder 202, which is threaded on it, to begin to move linearly along the connection between it and the guide rod 203. At this time, the slide cylinder 202, through the push rod 204 hinged to it, begins to push the abutment plate 205. At the same time, the two push rods 204 are symmetrically arranged on the abutment plate 205, so that the abutment plate 205 can slide smoothly, thereby making the buffer pad 20 fixedly connected to the abutment plate 205 slide smoothly. 6. The buffer pad 206 gradually contacts the back cover 101. When the buffer pad 206 contacts the back cover 101, the rotating head 209 continues to apply a pushing force to the back cover 101 through the abutment plate 205, so that the back cover 101 gradually separates from the cover plate 201. At the same time, since both the back cover 101 and the cover plate 201 are made of materials with high hardness, deformation on both sides can be effectively avoided, so that the cover plate 201 can be separated from the back cover 101 as a whole. During this process, the two rubber heads 304 are always pressed against the back cover 101 under the action of the spring 302, so that the two rubber heads 304 cooperate with each other to limit the back cover 101, so as to prevent the user from accidentally touching the back cover 101 after the back cover 101 is removed, causing the back cover 101 to fall to the ground and be damaged.

[0032] When the user needs to remove the back cover 101, they can press the pressure blocks 306 on both sides or any one side to make the pressure blocks 306 slide within the slide frame 305, thereby driving the connecting block 303 fixedly connected to it. This causes the connecting block 303 to compress the spring 302 fixedly connected to it and begin to slide into the back plate 205. At this time, the rubber head 304 stops contacting the back cover 101, and the user can then remove the back cover 101 and rotate the rotating head 209 to reset the back plate 205, thus avoiding affecting the user's maintenance.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0035] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0036] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0037] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0038] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0039] 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.
