Description

Technical Field

[0001] This utility model relates to the field of display screen cabinet processing technology, and in particular to a locking fixture for display screen cabinets. Background Technology

[0002] In the field of display manufacturing, the display cabinet is the core structural component that carries the display module, driving circuit and heat dissipation components. Its processing accuracy and assembly stability directly affect the display effect, service life and maintenance efficiency of the display.

[0003] The positioning reference adjustment of existing locking structures is cumbersome, requiring multiple trial fittings and calibrations to determine the clamping position. For example, using clamping cylinders set in different directions requires clamping cylinders to be set in the X-axis, Y-axis, and Z-axis directions respectively. During positioning and locking, the clamping cylinders in different directions move linearly to perform positioning and locking. However, each individual cylinder has its own locking surface, and when performing individual actions, it is necessary to adjust in conjunction with the locking in other directions. This operation is relatively troublesome and the structure is complex. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a locking fixture and clamping device for a display screen cabinet, which can be positioned with a positioning plate as a reference, and the positioning part of the positioning locking rod moves downward to lock the workpiece. The locking state is stable and the structure is simple.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A locking fixture for a display screen enclosure includes,

[0007] A positioning base is provided with a positioning plate, a positioning locking rod, and a positioning space; the positioning plate is parallel to the horizontal direction; the positioning plate is provided with a positioning hole that extends through to the positioning space; the positioning locking rod includes a first end and a second end, the first end passes through the positioning hole and can move in the vertical direction, the first end is provided with a positioning part, and the second end extends out of the positioning space through the positioning hole; the second end is provided with a linkage part.

[0008] A locking mechanism includes a locking seat, a driving member, and a linkage block. The linkage block is provided with a connecting part. The driving member is connected to the locking seat and is used to drive the linkage block to move horizontally, so that the connecting part moves closer to or away from the positioning space. After moving closer to the positioning space, the connecting part abuts against the linkage part to drive the linkage part to move downward and link the positioning part to move downward.

[0009] As an optional implementation, the linkage block is provided with a connecting arm; the driving component includes a driving cylinder and a connecting rod, the cylinder body of the driving cylinder is mounted on the locking seat, the piston rod of the driving cylinder is hinged to the top of the connecting arm, the linkage block is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the locking seat.

[0010] As an optional implementation, the connecting arms are provided on both sides of the linkage block, and the connecting arms on both sides are spaced apart to form an assembly gap. The piston rod of the drive cylinder extends into the assembly gap and is hinged to the connecting arm through a connecting shaft.

[0011] As an optional implementation, a gasket is held between the connecting shaft and the connecting arm.

[0012] As an optional implementation, the locking seat is provided with a connecting block, and the connecting rods are hinged to both sides of the connecting block. The linkage block passes through the two connecting rods and is hinged to the two connecting rods.

[0013] As an optional implementation, the linkage block is provided with a positioning notch; the positioning notch allows the positioning locking rod to pass through, so that the linkage block is pressed against the upper end of the linkage part.

[0014] As an optional implementation, the linkage includes a protruding head that protrudes from the positioning locking rod.

[0016] As an optional implementation, the positioning base includes two support sections and a connecting section. The connecting section is connected between the two support sections, and the positioning plate is connected to the top of the two support sections and the connecting section, together forming the positioning space.

[0017] A clamping device for a display screen enclosure includes a clamping base and a plurality of locking fixtures for the display screen enclosure, wherein the locking fixtures are mounted on the clamping base.

[0018] In summary, this utility model has the following technical effects:

[0019] During positioning, the bottom of the workpiece is supported by a positioning plate parallel to the horizontal direction, allowing the horizontal plane to serve as the positioning reference surface. During locking, the linkage at the second end of the positioning locking rod is pressed downwards, causing the positioning part at the first end of the positioning locking rod to press downwards. Therefore, the workpiece is locked vertically by the positioning part and the positioning plate, resulting in a stable locking state and reducing vibration during processing. Furthermore, since the positioning locking rod passes through the through hole, its left-right and front-back sway can be limited by the through hole. This ensures that the positioning part of the positioning locking rod remains relatively stable in both its front-back and left-back positions after locking, resulting in a stable clamping state.

[0033] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0034] See Figures 1-6This utility model discloses a locking fixture for a display screen enclosure, including a positioning base 10 and a locking mechanism. The positioning base 10 is provided with a positioning plate 11, a positioning locking rod 12, and a positioning space 13, with the positioning plate 11 parallel to the horizontal direction. The positioning plate 11 is provided with a positioning hole 111, which extends into the positioning space 13. Specifically, the positioning locking rod 12 includes a first end and a second end. The first end passes through the positioning hole 111 and can move vertically, and is provided with a positioning part 121. The second end extends out of the positioning space 13 through the positioning hole 111; the second end is provided with a linkage part.

[0035] The aforementioned locking mechanism includes a locking seat 30, a driving member 20, and a linkage block 40. The linkage block 40 is provided with a connecting portion. The driving member 20 is connected to the locking seat 30, and the driving member 20 can drive the linkage block 40 to move horizontally, so that the connecting portion moves closer to or away from the positioning space 13. After moving closer to the positioning space 13, the connecting portion abuts against the linkage portion, so that the linkage portion moves downward, and the positioning portion 121 moves downward in conjunction with the linkage.

[0036] Based on the above structure, when using the locking fixture for the display screen housing of this utility model, during workpiece assembly, the workpiece can be placed on the positioning plate 11 of the positioning seat 10, and the positioning locking rod 12 can move upward through the hole in the workpiece. Then, during the locking action, the driving component 20 drives the linkage block 40 to move closer to the positioning space 13. After the linkage block 40 approaches the positioning space 13, the connecting part of the linkage block 40 can abut against the linkage part, and during the gradual approach, it presses downward against the linkage part to drive the linkage part downward. In this way, the positioning part 121 located at the first end of the positioning locking rod 12 can move downward and press against the workpiece, achieving workpiece locking and positioning.

[0037] During positioning, the bottom of the workpiece is supported by a positioning plate 11 parallel to the horizontal direction, allowing the horizontal plane to serve as the positioning reference plane. During locking, the linkage at the second end of the positioning locking rod 12 is pressed downwards, causing the positioning part 121 at the first end of the positioning locking rod 12 to press downwards. Therefore, the workpiece is locked vertically by the positioning part 121 and the positioning plate 11, resulting in a stable locking state and reducing vibration during processing. Furthermore, since the positioning locking rod 12 passes through a through hole, its left-right and front-back sway can be limited by the through hole. Thus, the positioning part 121 of the positioning locking rod 12 remains relatively stable in both its front-back and left-back positions after positioning and locking, ensuring a stable clamping state.

[0038] Furthermore, when the workpiece needs to be removed, the driving component 20 drives the connecting part of the linkage block 40 away from the positioning space 13 of the positioning seat 10, so that the linkage block 40 is separated from the linkage. In this way, the positioning part 121 of the positioning locking rod 12 can be released from the workpiece, and the workpiece can be removed at this time, which is convenient for disassembly and assembly.

[0039] As an optional implementation, a connecting arm 42 may also be provided in the linkage block 40; the driving component 20 includes a driving cylinder and a connecting rod 31, the cylinder body 21 of the driving cylinder is mounted on the locking seat 30, the piston rod 22 of the driving cylinder is hinged to the top of the connecting arm 42, the linkage block 40 is hinged to one end of the connecting rod 31, and the other end of the connecting rod 31 is hinged to the locking seat 30.

[0040] Thus, when the positioning locking rod 12 is locked, the piston rod 22 of the drive cylinder extends toward the positioning space 13. Since the piston rod 22 of the drive cylinder can drive the linkage block 40 connected to it via the connecting arm 42 toward the positioning space 13, the connecting part of the linkage block 40 abuts against the linkage part of the positioning locking rod 12. After that, the piston rod 22 of the drive cylinder continues to extend. Since the piston rod 22 of the drive cylinder is hinged to the connecting arm 42 of the linkage block 40, and the bottom end of the linkage block 40 is hinged to the locking seat 30 via the connecting rod 31, the linkage block 40 has a tendency to swing downward relative to the locking seat 30. After the piston rod 22 of the drive cylinder continues to extend forward, the force applied by the piston rod 22 of the drive cylinder to the linkage block 40 can make the linkage block 40 swing downward. The abutment between the connecting part of the linkage block 40 and the linkage part can guide the positioning locking rod 12 to move downward. In this way, the positioning part 121 of the positioning locking rod 12 can press the workpiece.

[0041] Of course, the aforementioned driving component 20 may also include a driving cylinder. The piston rod 22 of the driving cylinder is connected to the linkage block 40. The connecting part of the linkage block 40 includes a pressing inclined block. In this way, after the piston rod 22 of the driving cylinder extends forward, the pressing inclined block can approach the linkage part. The inclined surface of the pressing inclined block cooperates with the linkage part to decompose the lateral force into a longitudinal force, guide the linkage part downward, and then drive the positioning locking rod 12 downward, so that the positioning part 121 is locked downward.

[0042] As an optional implementation, the linkage block 40 is provided with connecting arms 42 on both sides, with a gap between the connecting arms 42 on both sides to form an assembly gap. The piston rod 22 of the drive cylinder extends into the assembly gap and is hinged to the connecting arm 42 through the connecting shaft 43. In this way, when the linkage block 40 is assembled with the piston rod 22 of the drive cylinder, the piston rod 22 of the drive cylinder can be assembled between the two connecting arms 42. When driving, the connecting arms 42 on both sides of the linkage block 40 are subjected to force, so the force is balanced during the driving process.

[0043] As an optional implementation, a shim 44 is clamped between the connecting shaft 43 and the connecting arm 42. Since the shim 44 is clamped between the connecting shaft 43 and the connecting arm 42, the damping between the connecting shaft 43 and the connecting arm 42 can be increased, the assembly of the piston rod 22 of the drive cylinder and the connecting block is more stable, and the hinge state is stable, reducing the shaking caused by external forces.

[0044] As an optional implementation, a connecting block can also be provided on the locking seat 30, with the connecting block protruding from the locking seat 30. In this way, connecting rods 31 are hinged on both sides of the connecting block, and the linkage block 40 passes through the two connecting rods 31 and is hinged to the two connecting rods 31. With the arrangement of the two connecting arms 42, the bottom end of the linkage block 40 is hinged to the connecting rods 31 on both sides of the locking block by the two connecting rods 31, so that the assembly structure is stable.

[0045] As an optional implementation, the connecting part includes a positioning notch 41. The positioning notch 41 is provided in the linkage block 40. The positioning notch 41 allows the positioning locking rod 12 to pass through, pressing the linkage block 40 against the upper end of the linkage part. When the piston rod 22 of the drive cylinder drives the linkage block 40 to move closer to the positioning space 13, the positioning notch 41 of the linkage block 40 allows the positioning locking rod 12 to pass through and is located at the upper end of the linkage part. As the piston rod 22 of the drive cylinder continues to extend, the linkage block 40 can then abut against the linkage part downwards, causing the positioning locking rod 12 to move downwards. During unlocking, the piston rod 22 of the drive cylinder retracts, causing the linkage block 40 to return to its original position. The positioning locking rod 12 exits the positioning notch 41 and disengages from the linkage block 40. Thus, the positioning part 121 of the positioning locking rod 12 can be released from the workpiece, allowing the workpiece to be removed.

[0046] As an optional implementation, the linkage part includes a protruding head 122 that protrudes from the positioning locking rod 12. An arc surface 1221 can be provided circumferentially at the bottom end of the protruding head 122. After the linkage block 40 approaches the positioning locking rod 12, it can abut against the protruding head 122, which has a larger abutting linkage surface and a more stable state.

[0047] Based on the structure of the connecting part being a positioning notch 41, after the positioning notch 41 of the linkage block 40 allows the positioning locking rod 12 to pass through, the bottom end of the linkage block 40 can cooperate with the top surface of the protrusion block. The positioning locking rod 12 is located in the middle of the positioning notch 41, and cooperates with the linkage block 40 with the protrusion head 122, having a contact surface in the circumferential direction, and the force is balanced during the driving process.

[0048] As an optional implementation, the positioning part 121 includes a positioning boss protruding from the positioning locking rod 12. The bottom end of the positioning boss is connected to the outer peripheral wall of the positioning locking rod 12 with an arc surface. In this way, after the positioning locking rod 12 moves downward, the positioning boss can move downward and press down on the workpiece. Since the positioning boss and the positioning locking rod 12 are connected with an arc surface, you can contact the workpiece with an arc surface during the pressing process, reducing the pressure damage to the workpiece during the positioning and locking process.

[0049] As an optional implementation, the positioning base 10 includes two support sections 14 and a connecting section 15. The connecting section 15 is connected between the two support sections 14, and the positioning plate 11 is connected to the top of the two support sections 14 and the connecting section 15, and together they enclose a positioning space 13.

[0050] Example 2,

[0051] A clamping device for a display screen cabinet includes a clamping base and a plurality of locking fixtures for the display screen cabinets. The structure of the locking fixtures is the same as that of the locking fixtures in Embodiment 1, and the positioning seat 10 of the locking fixtures is mounted on the clamping base.

[0052] Specifically, four locking fixtures can be set around the clamping base, with the positioning plates 11 of the four locking fixtures supporting the four sides of the workpiece. Then, the positioning part 121 of the positioning locking rod 12 of each locking fixture can be pressed down to lock, thereby positioning and locking the four sides of the workpiece.

[0053] Of course, depending on the size of the workpiece, six, eight or more locking fixtures can be set on the clamping base, depending on the different workpiece structures.
