Description

Technical Field

[0001] This application belongs to the field of LED equipment fixture technology, and more specifically, relates to an LED cabinet clamp. Background Technology

[0002] With the continuous development of LED display technology, large-scale LED display equipment, with its advantages of high brightness, high definition, and wide viewing angle, has been widely used in many fields such as outdoor advertising, sports stadiums, stage performances, and monitoring and command centers. To ensure that LED display equipment presents a uniform and consistent display effect, the calibration of the LED cabinet is a crucial step in the product manufacturing and subsequent maintenance process.

[0003] In the standard LED product calibration process, the connection between the calibration fixture and the LED housing is typically achieved by using screws to secure the connecting plates. Specifically, before calibration, the operator must precisely align the LED housing with the preset position of the calibration fixture, and then tighten the screws to secure the connecting plates to both the housing and the calibration fixture, thus completing the housing installation. After calibration is completed, the screws must be loosened to release the connecting plates and disassemble the housing.

[0004] However, this cabinet assembly and disassembly method, which relies on screws to secure the connecting pieces, has a significant efficiency bottleneck. Throughout the calibration process, both tightening and loosening the screws are additional actions that do not directly contribute to the calibration. Operators not only expend considerable time and effort tightening the screws, but also need to carefully align the cabinet and calibration fixture before tightening to ensure the installation accuracy of the connecting pieces. This further increases the complexity and time cost of the operation. Especially in batch calibration scenarios for large LED display equipment, each cabinet assembly and disassembly requires repeating the aforementioned screw-tightening action. The accumulation of numerous valueless additional operations severely restricts the overall efficiency of LED product calibration operations, making it difficult to meet the demands of modern production for high-efficiency operations. Utility Model Content

[0005] The purpose of this application is to provide an LED cabinet clamp to solve the problem of low clamping efficiency of existing LED cabinet clamps.

[0006] To achieve the above objectives, according to one aspect of this application, an LED cabinet clamp is provided for clamping LED cabinets. The LED cabinet clamp includes: a base; a clamping assembly, the clamping assembly including two clamping parts, the two clamping parts being rotatably mounted on the base in opposite directions, each clamping part including a clamping structure and a driving structure connected to the clamping structure; the two driving structures are arranged facing each other, the two clamping structures having clamping positions that can respectively press against both sides of the LED cabinet and clearance positions that avoid the sides of the LED cabinet; the two driving structures can be pressed down by the LED cabinet to drive the two clamping structures to switch from the clearance position to the clamping position, and when the two clamping structures are in the clamping position, the two driving structures abut against the base.

[0007] Optionally, the clamping part further includes a first limiting structure and a second limiting structure. The first limiting structure is disposed on the clamping structure, and the second limiting structure is disposed on the driving structure. When the two clamping structures are in the clamping position, the two limiting structures abut against the front or back of the LED box.

[0008] Optionally, the LED housing fixture also includes a movable base, which is movably mounted on the base along a first direction, and the clamping part is rotatably mounted on the movable base.

[0009] Optionally, there are two movable seats, and the two clamping parts are arranged on the two movable seats in a one-to-one correspondence.

[0010] Optionally, the base is provided with two parallel guide rails, and a guide rail groove is formed between the two guide rails. The guide rail groove extends along a first direction, and the movable seat is movably disposed in the guide rail groove.

[0011] Optionally, the base is provided with an adjustment elongated hole that extends along a first direction, and the bottom of the movable seat is provided with a guide post that passes through the adjustment elongated hole.

[0012] Optionally, the guide post passes through the adjustment elongated hole, and the side of the guide post is provided with external threads. The LED housing clamp also includes a locking nut, which is screwed onto the part of the guide post that passes through the adjustment elongated hole.

[0013] Optionally, the LED housing clamp includes a reset elastic part, one end of which abuts against the base and the other end against the drive structure, so as to apply an elastic force to the clamping part to rotate it in opposite directions.

[0014] Optionally, the movable seat is provided with a limiting part, and when the two clamping structures are in the avoidance position, the top of the limiting part abuts against the bottom of the clamping structure.

[0015] Optionally, the clamping structure is provided with a buffer part, which is used to abut against the side of the LED cabinet.

[0016] The beneficial effects of the LED cabinet clamp provided in this application are as follows: By utilizing two opposing rotating clamping parts and through the linkage between the drive structure and the LED cabinet, the cabinet clamping process is automated. When the LED cabinet is placed on the base, its own weight presses down on the two opposing drive structures, directly causing the clamping structure to automatically switch from a clearance position to a clamping position, eliminating the need for manual screw tightening. When disassembling the cabinet, simply removing the pressure of the LED cabinet on the drive structure allows the clamping structure to disengage, eliminating the need for loosening screws in traditional methods. This fundamentally eliminates the two non-value-adding actions of tightening and loosening screws during calibration operations, significantly simplifying the cabinet assembly and disassembly process.

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] As described in the background section, in a conventional LED product calibration process, the connection between the calibration fixture and the LED housing is typically achieved by using screws to secure the connecting plates. Specifically, before performing calibration, the operator must precisely align the LED housing with the preset position of the calibration fixture, and then tighten the screws to secure the connecting plates to both the housing and the calibration fixture, thus completing the housing fixation. After the calibration is completed, the operator must loosen the screws to release the connecting plates and disassemble the housing.

[0038] However, this cabinet assembly and disassembly method, which relies on screws to secure the connecting pieces, has a significant efficiency bottleneck. Throughout the calibration process, both tightening and loosening the screws are additional actions that do not directly contribute to the calibration. Operators not only expend considerable time and effort tightening the screws, but also need to carefully align the cabinet and calibration fixture before tightening to ensure the installation accuracy of the connecting pieces. This further increases the complexity and time cost of the operation. Especially in batch calibration scenarios for large LED display equipment, each cabinet assembly and disassembly requires repeating the aforementioned screw-tightening action. The accumulation of numerous valueless additional operations severely restricts the overall efficiency of LED product calibration operations, making it difficult to meet the demands of modern production for high-efficiency operations.

[0039] To solve the above problem, see Figures 1 to 7 As shown, the LED box fixture in this embodiment is used to clamp an LED box 1. The LED box fixture includes a base 10 and a clamping assembly 20. The clamping assembly 20 includes two clamping parts 21, which are rotatably mounted on the base 10. Each clamping part 21 includes a clamping structure 211 and a driving structure 212 connected to the clamping structure 211. The two driving structures 212 are arranged facing each other. The two clamping structures 211 have clamping positions that can press against both sides of the LED box 1 and clearance positions that avoid the sides of the LED box 1. The two driving structures 212 can be pressed down by the LED box 1 to drive the two clamping structures 211 to switch from the clearance position to the clamping position. When the two clamping structures 211 are in the clamping position, the two driving structures 212 abut against the base 10.

[0040] It should be noted that the base 10 is the fundamental load-bearing component of the LED cabinet fixture, providing an installation and support platform for the other structures of the fixture. The clamping assembly 20 is the component that realizes the LED cabinet clamping function. Its overall function is to stably clamp or avoid the LED cabinet 1 through structural linkage. It consists of two opposing clamping parts 21. Through the coordinated action of the two clamping parts 21, the clamping, fixing, disassembly, and release operations of the LED cabinet are completed. It is a key component for the fixture to realize the automated clamping function. The clamping part 21 is the basic building block of the clamping assembly 20. Each clamping part 21 includes two functional parts: a clamping structure 211 and a driving structure 212. The two clamping parts 21 are mounted on the base 10 in a rotatable manner, and can switch positions through rotation, thereby completing the clamping or avoidance action of the LED cabinet. It is the direct structure for transmitting power and performing clamping operations.

[0041] It should be noted that the clamping structure 211 is the part of the clamping section 21 that directly contacts and presses against the LED cabinet to fix it in place. It has two working positions: in the clamping position, it can tightly press against both sides of the LED cabinet, ensuring that the cabinet does not shift during the calibration process by applying clamping force; in the clearance position, it disengages from the LED cabinet, providing space for the placement and removal of the cabinet, and is the key structure for achieving physical fixation of the cabinet. The driving structure 212 is the part of the clamping section 21 that receives external forces and converts them into the driving force for the clamping structure 211. The two driving structures 212 are arranged facing each other. Their core function is that when the LED cabinet is placed, it is pressed down by the weight of the cabinet itself, and through mechanical linkage, it drives the clamping structure 211 to switch from the clearance position to the clamping position; when the clamping structure 211 is in the clamping position, the driving structure 212 rests against the base 10, providing stable support for the clamping structure 211 and completing the transmission and conversion of force, thus serving as the power transmission structure for automated clamping.

[0042] The clamping position is one of the working positions of the clamping structure 211, referring to the state where the two clamping structures 211 press against both sides of the LED cabinet, forming a stable and fixed clamping position. In this position, the clamping structures 211 generate clamping force through close contact with the cabinet, ensuring that the LED cabinet maintains the preset posture and position during the calibration operation, thus guaranteeing calibration accuracy. The avoidance position is the non-working position of the clamping structure 211, referring to the state where the two clamping structures 211 are not in contact with the sides of the LED cabinet. In this position, the clamping structures 211 provide sufficient operating space for the placement and removal of the LED cabinet, avoiding interference with the loading and unloading process, and is a necessary state for achieving convenient loading and unloading of the cabinet.

[0043] The fixture in this embodiment automates the LED cabinet clamping process by using two opposing rotatable clamping parts 21 and the linkage between the drive structure 212 and the LED cabinet. When the LED cabinet is placed on the base 10, its own weight presses down on the two opposing drive structures 212, directly causing the clamping structure 211 to automatically switch from the avoidance position to the clamping position, eliminating the need for manual screw tightening. When disassembling the cabinet, simply removing the pressure of the LED cabinet on the drive structure 212 allows the clamping structure 211 to disengage, eliminating the need for loosening screws in traditional methods. This fundamentally eliminates the two non-value-added extra actions of tightening and loosening screws during calibration operations, significantly simplifying the cabinet assembly and disassembly process.

[0044] Traditional screw-locking methods require operators to precisely align the cabinet and connecting piece before repeatedly tightening the screws, a cumbersome and time-consuming process. This fixture, through the linkage design of the drive structure 212 and the clamping structure 211, simplifies cabinet clamping into a continuous "placement-automatic clamping" action, eliminating the need for manual intervention and significantly reducing the clamping time per cycle. In batch calibration scenarios for large LED display equipment, each cabinet disassembly and assembly saves the cumulative time spent tightening screws, effectively improving overall calibration efficiency and better meeting the high-efficiency requirements of modern mass production.

[0045] The clamping part 21 in this embodiment further includes a first limiting structure 213 and a second limiting structure 214. The first limiting structure 213 is disposed on the clamping structure 211, and the second limiting structure 214 is disposed on the driving structure 212. When the two clamping structures 211 are in the clamping position, the two limiting structures abut against the front or back of the LED cabinet. LED cabinet calibration requires extremely high positional accuracy; even slight displacement of the cabinet can lead to inaccurate calibration data, affecting the final display effect. By abutting against the front or back of the cabinet, the first limiting structure 213 and the second limiting structure 214 can precisely restrict the cabinet's degrees of freedom in the front-back direction, ensuring that the cabinet remains in the preset reference position throughout the calibration process. This reduces calibration errors caused by cabinet position deviations, improves the accuracy and reliability of the calibration results, and provides strong support for the high-quality display of LED display devices. The setting of the limiting structures does not change the core linkage mechanism of the original clamping part 21, and their position and abutment method can be adapted to the front and back structural characteristics of different specifications of LED cabinets. Regardless of the thickness or size of the LED cabinet, when the clamping structure 211 is in the clamping position, the first limiting structure 213 and the second limiting structure 214 can stably abut against the corresponding parts of the cabinet to achieve reliable limiting.

[0046] The LED cabinet clamp in this embodiment further includes a movable base 30, which is movably mounted on the base 10 along a first direction, and the clamping part 21 is rotatably mounted on the movable base 30. The movable base 30 is movable along the first direction, allowing the clamping part 21 mounted thereon to be flexibly adjusted in position according to the size specifications of the LED cabinet. For LED cabinets of different widths, thicknesses, or sizes, operators can adjust the position of the movable base 30 on the base 10 to change the relative distance between the two clamping parts 21, ensuring that the clamping structure 211 accurately corresponds to the clamping points on both sides of the cabinet. This significantly improves the clamp's adaptability to LED cabinets of different specifications, eliminating the need to design separate clamps for specific cabinets and reducing equipment investment costs.

[0047] In LED cabinet calibration operations, different models of cabinets may require different clamping positions to ensure calibration accuracy. The movable feature of the movable base 30 provides a convenient way to adjust the position of the clamping part 21. Operators can smoothly move the movable base 30 along the first direction according to actual needs to quickly complete the position calibration of the clamping part 21. Compared with the traditional method that requires disassembly and reassembly to adjust the clamping position, this significantly shortens the adjustment time, reduces the number of operation steps, and improves the flexibility and convenience of the clamping process, making it especially suitable for calibration operations involving multiple varieties and small batches.

[0048] In this embodiment, there are two movable seats 30, with two clamping parts 21 correspondingly mounted on each of the two movable seats 30. The independent adjustment function of the two movable seats 30 provides a more flexible operating space: they can be moved synchronously to maintain the symmetrical distribution of the clamping parts 21, meeting the clamping requirements of conventional symmetrical boxes; or they can be adjusted asynchronously to form an asymmetrical clamping layout, adapting to the clamping requirements of boxes with special structures. This eliminates the limitation of a single movable seat 30 driving the synchronous movement of the clamping parts 21 on both sides, enabling the fixture to cope with more diverse clamping scenarios and improving the operational flexibility of the equipment. When the two clamping parts 21 are installed on independent movable seats 30, the position adjustment of each clamping part 21 can more accurately match the force requirements on both sides of the LED box. Operators can adjust the positions of the two movable seats 30 according to the characteristics of the box's center of gravity distribution and structural strength, so that the clamping force applied by the two clamping parts 21 is more evenly distributed on both sides of the box. Especially for large LED boxes or those with uneven weight distribution, the independent adjustment function can effectively improve clamping stability and ensure the safety and accuracy of the calibration operation.

[0049] In this embodiment, the base 10 is provided with two parallel guide rails 11, forming a guide rail groove 12 between the two guide rails 11. The guide rail groove 12 extends along a first direction, and the movable seat 30 is movably disposed in the guide rail groove 12. The guide rail groove 12 formed by the two parallel guide rails 11 provides a stable support and guiding frame for the movable seat 30, effectively limiting the lateral swaying and offset of the movable seat 30 during movement. Compared with a sliding structure without guide rails, the cooperation between the guide rails 11 and the guide rail groove 12 significantly improves the anti-overturning ability of the movable seat 30, ensuring that it can still move smoothly when bearing the weight of the clamping part 21 and the LED cabinet. The enhanced structural rigidity avoids the positional deviation of the clamping part 21 caused by the swaying of the movable seat 30, providing a basic guarantee for the stability and correction accuracy of the subsequent cabinet clamping.

[0050] The guide rail groove 12 extends along the first direction, providing precise guiding constraints for the movement path of the movable seat 30, ensuring that the movable seat 30 can only move linearly along the preset first direction, avoiding offset or skew. When adjusting the position of the movable seat 30, operators do not need to repeatedly calibrate the movement direction; the precise positioning of the movable seat 30 can be achieved through the guidance of the guide rail groove 12. The precise guiding characteristic makes the relative distance adjustment between the two clamping parts 21 more accurate, better matching the size requirements of LED cabinets of different specifications, and further improving the size adaptation accuracy of the fixture.

[0051] See Figure 6 As shown, in this embodiment, the base 10 is provided with an adjustment elongated hole 13, which extends along a first direction. A guide post 31 is provided at the bottom of the movable seat 30, passing through the adjustment elongated hole 13. The layout of the adjustment elongated hole 13 extending along the first direction provides a clear movement path constraint for the guide post 31. When the guide post 31 passes through the adjustment elongated hole 13, it effectively limits the lateral and longitudinal offset of the movable seat 30, ensuring that the movable seat 30 can only move stably along the preset first direction. The combined structure and the guide rail groove 12 form a double guiding and limiting effect, further reducing the shaking or tilting of the movable seat 30 during adjustment, making the position adjustment of the movable seat 30 more precise and controllable, and providing a reliable guarantee for the clamping part 21 to align with the clamping points on both sides of the LED cabinet.

[0052] In this embodiment, the guide post 31 passes through the adjustment elongated hole 13, and the side of the guide post 31 is provided with external threads. The LED housing clamp also includes a locking nut 32, which is screwed onto the portion of the guide post 31 that passes through the adjustment elongated hole 13. After the movable seat 30 is adjusted to the target position, the locking nut 32 is screwed on to make it tightly abut against the surface of the base 10, thus firmly fixing the guide post 31 and the movable seat 30 in the preset position of the adjustment elongated hole 13. The threaded locking method can provide a continuous and stable clamping force, effectively preventing the movable seat 30 from shifting due to factors such as vibration, external impact, or the weight of the housing during the calibration operation.

[0053] The threaded engagement between the locking nut 32 and the guide post 31 is adjustable. Operators can easily adjust the position of the movable seat 30 by loosening the locking nut 32, and then tighten the nut to secure it. The "adjust-lock" operation process is flexible and convenient, allowing for multiple position adjustments of the movable seat 30 without disassembling any parts. This enables rapid adaptation to the clamping requirements of LED cabinets of different widths and sizes. In scenarios involving the alternating calibration of various LED cabinet types, this significantly reduces changeover and adjustment time, improving the equipment's versatility and operational efficiency.

[0054] The locking nut 32, guide post 31, adjusting elongated hole 13, and movable seat 30 form a complete fixing system, which works synergistically with the guiding function of guide rail groove 12. Guide rail groove 12 restricts the movement direction of movable seat 30, adjusting elongated hole 13 and guide post 31 achieve precise positioning, and locking nut 32 firmly locks this positional relationship. The three work together to form a closed-loop structure of "guiding-positioning-locking".

[0055] The LED cabinet clamp in this embodiment includes a reset elastic part 40. One end of the reset elastic part 40 abuts against the base 10, and the other end abuts against the drive structure 212 to apply a spring force to the clamping part 21, causing it to rotate in opposite directions. When the LED cabinet is completed and removed, the spring force of the reset elastic part 40 is released, pushing the drive structure 212 to drive the clamping part 21 to rotate in opposite directions, so that the clamping structure 211 automatically switches from the clamping position to the avoidance position. This process does not require the operator to manually operate the clamping part 21 to reset, completely eliminating the extra action of manually releasing the fixation required when disassembling traditional clamps.

[0056] During the placement of LED cabinets, a certain amount of impact force is inevitable. The reset elastic part 40 can absorb part of the impact force through its own deformation during the rotation of the clamping part 21, thus playing a buffering and protective role. On the one hand, it reduces the rigid collision between the clamping structure 211 and the cabinet, avoiding scratches or damage to the surface of the cabinet due to impact; on the other hand, it reduces the transmission of impact force to structures such as the base 10 and the moving seat 30, reducing structural fatigue damage during long-term use and extending the service life of the clamp.

[0057] The elastic reset part can be a compression spring or a torsion spring, etc. In a specific embodiment, the compression spring can be arranged along the rotation direction of the clamping part 21, with one end sleeved on the fixed post of the base 10 and the other end abutting against the protruding part of the drive structure 212. When the LED box presses down on the drive structure 212, the clamping part 21 rotates in opposite directions and compresses the spring, causing the spring to accumulate elastic potential energy; when the box is removed, the spring releases its potential energy to push the drive structure 212 to reset, causing the clamping part 21 to rotate in opposite directions to the avoidance position.

[0058] In this embodiment, the movable base is provided with a limiting part 50. When the two clamping structures 211 are in the avoidance position, the top of the limiting part 50 abuts against the bottom of the clamping structure 211. By engaging with the bottom of the clamping structure 211, the limiting part 50 sets a clear reference boundary for the avoidance position of the clamping structure 211. When the reset elastic part 40 pushes the clamping part 21 to rotate in opposite directions to the avoidance state, the bottom of the clamping structure 211 stops rotating after contacting the top of the limiting part 50, avoiding excessive rotation caused by excessive elastic force of the elastic part or rotational inertia of the clamping part 21. This ensures that after each disassembly of the box, the two clamping structures 211 can accurately stop at the preset avoidance position, making the subsequent box placement alignment smoother, reducing box placement difficulties caused by avoidance position deviations, and improving the consistency and reliability of the clamping operation.

[0059] When the clamping structure 211 is in the avoidance position, the stable support of the limiting part 50 keeps the clamping part 21 in a stable state, preventing accidental rotation of the clamping part 21 due to external force or vibration. This reduces the risk of operators being accidentally pinched by the clamping structure 211 when placing or removing LED cabinets, and also prevents the clamping part 21 from shaking and interfering with the alignment of the cabinets, providing a safer operating environment for operators. The safety protection function of the limiting part 50 is particularly prominent in batch operations or high-frequency operation scenarios.

[0060] The limiting part 50 is a limiting post extending along the height direction. A cushioning rubber is provided at the top of the limiting post.

[0061] The clamping structure 211 in this embodiment is provided with a buffer portion 60, which is used to abut against the side of the LED cabinet. The side of the LED cabinet typically houses precision electronic components, circuit interfaces, or decorative housings. When the traditional clamping structure 211 makes direct hard contact with the side of the cabinet, excessive clamping force or the presence of small protrusions or burrs may cause scratches, dents, or even damage to the internal components on the cabinet surface. The buffer portion 60 is made of an elastic material (such as rubber, silicone, polyurethane, etc.), and during clamping, it forms a flexible contact with the side of the cabinet through its own deformation, effectively dispersing the clamping force and preventing localized stress concentration from damaging the cabinet surface. This is particularly suitable for LED cabinets with high appearance requirements or easily damaged surfaces, significantly improving the quality protection effect of the product during clamping.

[0062] At the instant the clamping structure 211 switches from the avoidance position to the clamping position, a certain impact force may be generated due to the elastic force of the reset elastic part 40 or the inertia of the mechanical transmission. The buffer part 60 absorbs this impact force through its own elastic deformation, reducing the vibration and impact load caused by hard contact. This not only avoids the impact force on the internal components of the LED cabinet, but also reduces the fatigue damage caused by the rigid collision between the clamping structure 211 and the cabinet to the fixture's own components (such as the connection parts of the clamping structure 211 and the drive structure 212), thus extending the service life of the fixture.

[0063] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
