Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brackets, in particular to a locking component and a maintenance bracket. Background Art
[0002] A splicing screen is formed by splicing multiple liquid crystal screens into a large display screen, and each liquid crystal screen is separately installed on a maintenance bracket. To facilitate maintenance when the splicing screen is installed in a narrow and enclosed area, the maintenance bracket mostly adopts a double-layer telescopic structure with hydraulic or gas springs to achieve the front-back telescoping of the liquid crystal screen during maintenance.
[0003] However, the existing maintenance brackets often accidentally telescope due to unstable factors such as accidental pressing, pushing, pulling by users, or vibration in the installation environment, thus affecting the normal use of the overall display screen. Summary of the Utility Model
[0004] Based on this, it is necessary to provide a locking component and a maintenance bracket for the above problems. The locking component can prevent the maintenance bracket from accidentally telescoping.
[0005] The utility model first provides a locking component for a maintenance bracket. The maintenance bracket includes a first bracket and a second bracket capable of moving relative to the first bracket. The locking component includes: a fixing member for being arranged on the first bracket; a locking member arranged on the fixing member and capable of moving relative to the fixing member. The locking member can move along a first preset direction to a locking state. In the locking state, the locking member can cooperate with the edge of the second bracket to limit the movement of the second bracket relative to the first bracket; and an unlocking member arranged on the locking member. The unlocking member can drive the locking member to move along the reverse direction of the first preset direction to an unlocking state. In the unlocking state, the locking member is separated from the second bracket.
[0006] In the above locking component, when it is necessary to repair or disassemble and assemble the display screen installed on the second bracket, control the unlocking member to drive the locking member to move along the reverse direction of the first preset direction to the unlocking state, so that the locking member is separated from the second bracket. At this time, the locking component does not limit the movement of the second bracket relative to the first bracket. The structure of the locking component is simple, and by controlling the unlocking member, the locking member can be driven from the locking state to the unlocking state, which is convenient for users to operate; after the repair or disassembly and assembly are completed, maintain the locking member in the unlocking state, control the second bracket to move relative to the first bracket to the retracted state, and control the locking member to move along the first preset direction to the locking state, so that the locking member cooperates with the edge of the second bracket. At this time, the locking component can limit the movement of the second bracket relative to the first bracket to the extended state, thereby ensuring the stability and reliability of the second bracket in the retracted state, avoiding accidental telescoping of the second bracket and the display screen, and ensuring the normal use of the maintenance bracket and the display screen.
[0007] In one embodiment, the lock attachment includes a first rotating portion and a limiting portion. The first rotating portion is disposed on the fixing member and can rotate relative to the fixing member about a preset axis. The limiting portion is disposed on a side surface of the first rotating portion facing the first preset direction. In the locked state, the limiting portion is limited to a side surface of the second bracket facing away from the first bracket.
[0008] With such a setting, by controlling the rotation of the first rotating portion relative to the fixing member, the limiting portion is engaged or separated from the second bracket, so as to realize the switching between the locked state and the unlocked state of the lock attachment. The movement mode of the lock attachment is simple, which is convenient for the user to control.
[0009] In one embodiment, the lock attachment further includes a reset portion disposed on a side surface of the first rotating portion facing the first preset direction. The reset portion is arranged at an interval with the limiting portion and is located on a side of the limiting portion close to the preset axis.
[0010] With such a setting, when the second bracket is controlled to move to the retracted state, the lock attachment can be controlled to move to the locked state through the cooperation between the second bracket and the reset portion, which simplifies the operation steps and is convenient for the user to control.
[0011] In one embodiment, the lock attachment further includes a second rotating portion disposed on a side surface of the first rotating portion facing the opposite direction of the first preset direction. The unlocking member is disposed on a side surface of the second rotating portion facing the first preset direction.
[0012] With such a setting, the unlocking member and the second rotating portion are convenient for the user to apply force when controlling the lock attachment to move to the unlocked state.
[0013] In one embodiment, the lock attachment assembly further includes a clamping member disposed on the fixing member. In the unlocked state, one end of the second rotating portion away from the first rotating portion is clamped with the clamping member.
[0014] With such a setting, the lock attachment can be stably in the unlocked state, without interfering with the movement of the second bracket, and the user does not need to always push against the unlocking member with an external tool, so as to be convenient for the user to control.
[0015] In one embodiment, the second rotating part is arranged at one end of the first rotating part close to the preset axis, and the unlocking part is arranged at one end of the second rotating part far from the preset axis; and / or, the second rotating part is provided with a sliding groove extending along a second preset direction, and the second preset direction is perpendicular to the preset axis; the unlocking part includes a connecting part and a pushing part arranged at one end of the connecting part far from the second rotating part, the connecting part includes a sliding block slidably arranged in the sliding groove, and the sliding block can rotate in the sliding groove.
[0016] With such an arrangement, the sliding block can slide and rotate in the sliding groove, so that the height and direction of the unlocking part can remain unchanged, ensuring that the tool can always be in contact with the pushing part; it is the most labor-saving when the unlocking part drives the locking accessory to rotate reversely along the preset direction around the preset axis.
[0017] In one embodiment, the locking assembly further includes an elastic member, and two ends of the elastic member are respectively connected to the fixing member and the locking accessory, and at least in the unlocking state, the elastic member is compressed.
[0018] With such an arrangement, the locking accessory can move along the preset direction to the locking state under the action of the elastic force of the elastic member, and the locking accessory is stabilized in the locking state.
[0019] In one embodiment, in the locking state, one side surface of the locking accessory facing the first preset direction abuts against the fixing member to limit the rotation of the locking accessory along the first preset direction.
[0020] With such an arrangement, the stability and reliability of the locking accessory in the locking state can be ensured.
[0021] The embodiment of the present utility model further provides a maintenance bracket, including: a first bracket; a second bracket arranged on the first bracket and capable of moving relative to the first bracket, and one side surface of the second bracket facing away from the first bracket is used for installing a display screen; and, the locking assembly as described above, and the fixing member is arranged on the first bracket.
[0022] In one embodiment, in the assembled state, at least part of the projection of the unlocking part on the display screen is located outside the display screen.
[0023] With such an arrangement, it can be ensured that when a user inserts an external tool into the gap between two adjacent display screens, the external tool can contact the unlocking part. Description of the Drawings

[0039] The splicing screen is composed of multiple liquid crystal screens spliced into a large display screen, and each liquid crystal screen is separately installed on a maintenance bracket. To facilitate maintenance when the splicing screen is installed in a narrow and enclosed area, the maintenance bracket mostly adopts a double-layer telescopic structure with hydraulic or gas springs to achieve the front-back telescoping of the liquid crystal screen during maintenance. However, the existing maintenance brackets often accidentally telescope due to unstable factors such as accidental pressing, pushing, pulling by users, or vibration in the installation environment, thus affecting the normal use of the overall display screen.
[0040] To solve the above problems, as Figures 1 to 8 shown, the present utility model first provides a locking component, which can prevent the maintenance bracket from accidentally telescoping.
[0041] As Figure 1 and Figure 4 shown, the locking component 100 is used for the maintenance bracket. The maintenance bracket includes a first bracket 200 and a second bracket 300 that can move relative to the first bracket 200. The first bracket 200 is used to be fixed to an external structure, and the second bracket 300 is used to install devices such as a display screen 400. In one embodiment, the second bracket 300 can move relative to the first bracket 200 in the ±Y direction shown in the figure to extend or retract, so as to drive the display screen 400 to extend or retract. Of course, in other embodiments, according to different installation environments, the second bracket 300 can also be set to be able to rotate or other movement modes relative to the first bracket 200, so that the second bracket 300 and the display screen 400 can be switched between the extended state and the retracted state.
[0042] As Figures 2 to 3 shown, specifically, the locking component 100 includes a fixing member 1, a locking member 2, and an unlocking member 3, where: the fixing member 1 is used to be arranged on the first bracket 200; the locking member 2 is arranged on the fixing member 1 and can move relative to the fixing member 1. The locking member 2 can move along a first preset direction to a locked state. In the locked state, the locking member 2 can cooperate with the edge of the second bracket 300 in the retracted state to limit the movement of the second bracket 300 relative to the first bracket 200; the unlocking member 3 is arranged on the locking member 2, and the unlocking member 3 can drive the locking member 2 to move in the reverse direction of the first preset direction to an unlocked state. In the unlocked state, the locking member 2 is separated from the second bracket 300.
[0043] In the locking assembly 100 provided by the embodiment of the present utility model, when it is necessary to repair or disassemble and assemble the display screen 400 installed on the second bracket 300, the control unlocking member 3 drives the locking member 2 to move in the reverse direction of the first preset direction to the unlocking state, so that the locking member 2 is separated from the second bracket 300. At this time, the locking assembly 100 does not limit the movement of the second bracket 300 relative to the first bracket 200. Thus, it is possible to control the second bracket 300 and the display screen 400 to move relative to the first bracket 200 in the +Y direction to the extended state. The structure of the locking assembly 100 is simple. By controlling the unlocking member 3, the locking member 2 can be driven to move from the locked state to the unlocked state, which is convenient for the user to operate. After the repair or disassembly and assembly are completed, the locking member 2 is maintained in the unlocked state. The second bracket 300 and the display screen 400 are controlled to move relative to the first bracket 200 to the retracted state, and the locking member 2 is controlled to move in the first preset direction to the locked state, so that the locking member 2 cooperates with the edge of the second bracket 300. At this time, the locking assembly 100 can limit the second bracket 300 to move relative to the first bracket 200 in the +Y direction to the extended state, thereby ensuring the stability and reliability of the second bracket 300 and the display screen 400 in the retracted state, and avoiding accidental expansion and contraction of the second bracket 300 and the display screen 400 due to unstable factors such as accidental pressing, pushing or pulling of the second bracket 300 by the user, or vibration of the installation environment, so as to ensure the normal use of the maintenance bracket and the display screen 400.
[0044] As Figure 5 and Figure 7 shown, in one embodiment, the locking member 2 can reciprocally rotate relative to the fixing member 1 about a preset axis a in the first preset direction. At this time, the first preset direction is the +X direction shown in the figure, and the reverse direction of the first preset direction is the -X direction shown in the figure. Specifically, the locking member 2 includes a first rotating portion 21 and a limiting portion 22. The first rotating portion 21 is disposed on the fixing member 1 and can rotate relative to the fixing member 1 about the preset axis a. The limiting portion 22 is disposed on a side surface of the first rotating portion 21 facing the first preset direction. As Figure 3 and Figure 5 shown, when the first rotating portion 21 rotates about the preset axis a in the +X direction to the locked state, the limiting portion 22 is limited to a side surface of the second bracket 300 facing away from the first bracket 200, so as to limit the second bracket 300 from moving relative to the first bracket 200 in the +Y direction to the extended state. As Figure 2 and Figure 7As shown, when the first rotating part 21 rotates around the preset axis a in the -X direction to the unlocked state, the limiting part 22 separates from the second bracket 300, and thus does not restrict the second bracket 300 from moving in the ±Y direction relative to the first bracket 200. In this way, by controlling the first rotating part 21 to rotate relative to the fixing member 1 so that the limiting part 22 cooperates with or separates from the second bracket 300, the lock component 2 is switched between the locked state and the unlocked state, and the movement mode of the lock component 2 is simple, which is convenient for user control.
[0045] The preset axis a is parallel to the edge of the second bracket 300 that can cooperate with the locking accessory 2. For example, when the locking accessory 2 can cooperate with the upper and lower edges of the second bracket 300 in the locked state, the preset axis a is parallel to the upper and lower edges of the second bracket 300; when the locking accessory 2 can cooperate with the left and right edges of the second bracket 300 in the locked state, the preset axis a is parallel to the left and right edges of the second bracket 300. Of course, the preset axis a can also be at an angle with the edge of the second bracket 300, as long as it is ensured that in the locked state, the locking accessory 2 can limit the second bracket 300 from moving to the extended state relative to the first bracket 200, and the embodiment of the utility model does not make specific restrictions here.
[0046] Of course, in other embodiments, the locking component 2 can also slide back and forth along the first preset direction relative to the fixing component 1, and the locking component 2 is close to the edge of the second bracket 300 when sliding toward the first preset direction, and is away from the second bracket 300 when sliding in the opposite direction of the first preset direction.
[0047] In one embodiment, the limiting portion 22 is configured as an arc-shaped hollow structure as shown in the figure to ensure the strength of the limiting portion 22, thereby ensuring the limiting effect on the second bracket 300. Of course, in other embodiments, the limiting portion 22 can also be configured as a plate-like structure or other structures that can abut against a side of the second bracket 300 away from the first bracket 200, and the embodiment of the utility model is not specifically limited here.
[0048] like Figures 5 to 8As shown, the lock attachment 2 further includes a reset portion 23 disposed on a side surface of the first rotating portion 21 facing the first preset direction. The reset portion 23 and the limiting portion 22 are arranged at intervals and are located on a side of the limiting portion 22 close to the preset axis a. In the unlocked state, when controlling the second bracket 300 to move relative to the first bracket 200 along the -Y direction, a side surface of the second bracket 300 facing the first bracket 200 can push against the reset portion 23, and the reset portion 23 can drive the first rotating portion 21 to rotate around the preset axis a along the +X direction to the locked state. Thus, while controlling the second bracket 300 to move to the retracted state, through the cooperation between the second bracket 300 and the reset portion 23, the lock attachment 2 can be controlled to move to the locked state, simplifying the operation steps and further facilitating user control. In the locked state, the reset portion 23 and the limiting portion 22 are respectively located on both sides of the second bracket 300.
[0049] Moreover, when controlling the unlocking member 3 to drive the lock attachment 2 to rotate around the preset axis a along the -X direction to the unlocked state, the reset portion 23 can also push the second bracket 300 along the +Y direction to assist the second bracket 300 to move relative to the first bracket 200 along the +Y direction.
[0050] As Figures 5 to 8 shown, the lock attachment 2 further includes a second rotating portion 24 disposed on a side surface of the first rotating portion 21 opposite to the first preset direction. The unlocking member 3 is disposed on a side surface of the second rotating portion 24 facing the first preset direction. The unlocking member 3 and the second rotating portion 24 can facilitate the user to apply force when controlling the lock attachment 2 to move to the unlocked state. When pushing the unlocking member 3 along the -X direction, the unlocking member 3 can apply a force along the -X direction to the second rotating portion 24, so as to drive the entire lock attachment 2 to rotate around the preset axis a along the -X direction through the second rotating portion 24, making the lock attachment 2 move to the unlocked state.
[0051] In the illustrated embodiment, the second rotating portion 24 is disposed at one end of the first rotating portion 21 close to the preset axis a, and the unlocking member 3 is disposed at one end of the second rotating portion 24 far from the preset axis a. In this way, it is the most labor-saving to drive the lock attachment 2 to rotate around the preset axis a along the -X direction through the unlocking member 3. Wherein, the included angle between the second rotating portion 24 and the first rotating portion 21 can be 90° as shown in the figure, or can be an acute angle or an obtuse angle. Of course, in other embodiments, the second rotating portion 24 can also be disposed at one end of the first rotating portion 21 far from the preset axis a or in the middle area of the first rotating portion 21, and the unlocking member 3 can also be disposed at one end of the second rotating portion 24 close to the preset axis a or in the middle area of the second rotating portion 24, as long as pushing the unlocking member 3 along the -X direction can drive the lock attachment 2 to rotate around the preset axis a along the -X direction, and the embodiments of the present invention do not make specific limitations here.
[0052] As Figures 5 to 8As shown, the second rotating part 24 is provided with a sliding groove 241 extending in a second preset direction (i.e., the ±Z direction shown in the figure), and the second preset direction is perpendicular to the preset axis a; the unlocking member 3 includes a connecting part 31 and a pushing part 32 provided at one end of the connecting part 31 away from the second rotating part 24. The connecting part 31 includes a slider 311 slidably disposed in the sliding groove 241, and the slider 311 can rotate in the sliding groove 241. For example, when the maintenance bracket is used for a splicing screen formed by splicing a plurality of display screens 400, the user can insert an external tool into the gap between two adjacent display screens 400 and push the pushing part 32 toward the -Y direction. The unlocking member 3 can drive the locking accessory 2 to rotate around the preset axis a in the -X direction. At the same time, the slider 311 can slide in the sliding groove 241 in the +Z direction and rotate in the sliding groove 241, so that the height and direction of the unlocking member 3 can remain unchanged, ensuring that the tool can always contact the pushing part 32, thereby ensuring the stability and reliability when the user controls the locking accessory 2 to move to the unlocking state through the unlocking member 3. When the locking accessory 2 rotates around the preset axis a in the +X direction to the locking state, the slider 311 can slide in the sliding groove 241 in the -Z direction and rotate reversely in the sliding groove 241 to reset.
[0053] Moreover, when the maintenance bracket is used for a splicing screen formed by splicing a plurality of display screens 400, at least part of the projection of the pushing part 32 on the display screen 400 is located outside the display screen 400, so as to ensure that when the user inserts an external tool into the gap between two adjacent display screens 400, the external tool can contact the pushing part 32.
[0054] Such as Figure 5 and Figure 7As shown, the locking assembly 100 further includes a clamping member 4 provided on the fixing member 1. In the unlocked state, the end of the second rotating portion 24 away from the preset axis a is clamped with the clamping member 4. After the unlocking member 3 controls the locking member 2 to move to the unlocked state, without applying an external force to the locking member 2, the clamping of the clamping member 4 and the second rotating portion 24 can stably hold the locking member 2 in the unlocked state. In this way, during the process of controlling the second bracket 300 to move relative to the first bracket 200 in the +Y direction to the extended state, inspecting or disassembling and assembling the display screen 400 installed on the second bracket 300, and controlling the second bracket 300 to move relative to the first bracket 200 in the -Y direction, the locking member 2 can be stably in the unlocked state, without interfering with the movement of the second bracket 300, and it is not necessary for the user to continuously push against the unlocking member 3 with an external tool, thus further facilitating user control. When the second bracket 300 pushes against the reset portion 23, the reset portion 23 can drive the entire locking member 2 to rotate in the +X direction around the preset axis a, so that the second rotating portion 24 is disengaged from the clamping member 4. Among them, the clamping member 4 can be set as an elastic reed. When the clamping member 4 deforms, the second rotating portion 24 can be clamped with or disengaged from the clamping member 4, while also ensuring the stability and reliability of the second rotating portion 24 and the clamping member 4 in the clamped state.
[0055] As Figure 6 and Figure 8 shown, the locking assembly 100 further includes an elastic member 5. Both ends of the elastic member 5 are respectively connected to the fixing member 1 and the locking member 2. At least in the unlocked state, the elastic member 5 is compressed. When the locking member 2 rotates in the -X direction around the preset axis a to the unlocked state, the elastic member 5 is compressed and can apply an elastic force in the +X direction to the locking member 2. When the second bracket 300 pushes against the reset portion 23 to disengage the second rotating portion 24 from the clamping member 4, the locking member 2 can rotate in the +X direction around the preset axis a to the locked state under the action of the elastic force of the elastic member 5 and stably hold the locking member 2 in the locked state. Among them, the elastic member 5 can be set as an element with elasticity such as a spring, an elastic reed, a silicone rubber member, etc. The embodiments of the present invention do not make specific limitations here.
[0056] It can be understood that the elasticity of the clamping member 4 needs to be greater than that of the elastic member 5 to prevent the elastic force of the elastic member 5 from being too large and causing the second rotating portion 24 to accidentally disengage from the clamping member 4, thereby further ensuring the stability and reliability of the second rotating portion 24 and the clamping member 4 in the clamped state.
[0057] As Figures 5 to 6As shown, in the locked state, one side of the lock attachment 2 facing the first preset direction abuts against the fixing member 1 to limit the rotation of the lock attachment 2 along the first preset direction. Specifically, the fixing member 1 includes a rotation stopping portion 11. In the locked state, one side of the lock attachment 2 facing the first preset direction abuts against the rotation stopping portion 11 to limit the lock attachment 2 from continuing to rotate along the +X direction around the preset axis a, thereby ensuring the stability and reliability of the lock attachment 2 in the locked state. Alternatively, it can also be that one side of the lock attachment 2 facing the first preset direction includes a rotation stopping portion 11, and in the locked state, the rotation stopping portion 11 abuts against the fixing member 1.
[0058] As Figure 1 and Figure 4 shown, an embodiment of the present invention further provides a maintenance bracket, including a first bracket 200, a second bracket 300, and the above-mentioned lock attachment assembly 100, wherein: the second bracket 300 is disposed on the first bracket 200 and can move relative to the first bracket 200. One side of the second bracket 300 facing away from the first bracket 200 is used to mount the display screen 400; the fixing member 1 is disposed on the first bracket 200. Specifically, the maintenance bracket further includes a telescopic assembly 500. Both ends of the telescopic assembly 500 are respectively connected to the first bracket 200 and the second bracket 300. The telescopic assembly 500 can be set as a scissor-type telescopic structure, a telescopic tube structure, a hinge structure, etc., which can control the second bracket 300 to extend or retract relative to the first bracket 200. The embodiment of the present invention does not make specific limitations here.
[0059] As Figure 4 shown, in the assembled state, at least part of the unlocking member 3 projects outside the display screen 400. That is to say, when looking directly at the display screen 400, at least part of the unlocking member 3 can be exposed outside the display screen 400. In this way, when the maintenance bracket is used for a splicing screen formed by splicing multiple display screens 400, it can be ensured that when a user inserts an external tool into the gap between two adjacent display screens 400, the external tool can contact the pushing portion 32 of the unlocking member 3.
[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0061] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application.
