Description

Technical Field

[0001] The invention belongs to the technical field of display screens, and in particular relates to an effective anti-fall transportation structure for an LED display screen. Background Art

[0002] The transportation of LED display screens is a process involving multiple links and details. LED display screens can be divided into many types according to application scenarios and performance characteristics, such as single-color and dual-color LED display screens, full-color LED display screens, outdoor LED display screens, indoor LED display screens, LED transparent screens, etc. Different types of LED display screens have different requirements and precautions during transportation. Conventional display screens are mainly placed in cartons supplemented with cushioning materials for transportation.

[0003] However, during the factory testing of the display screen, no special cartons are set up for the transportation of the display screen. Generally, a clamp is used to transport the display screen. When in use, the operator needs to operate the clamp to clamp the display screen. The whole process is relatively cumbersome, which is a bit inconvenient when transporting a large number of display screens.

[0004] At the same time, due to the different heights of display screens, during actual transportation, the universal clamps used are difficult to effectively support higher display screens. The lack of support at the top of the display screen causes the risk of the display screen falling, which urgently needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide an effective anti-fall transportation structure for an LED display screen to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an effective anti-fall transportation structure for an LED display screen, comprising a base, a movable base is provided inside the base, and slots are provided on the front and rear sides of the inner cavity of the base, and blocks are fixedly installed on the front and rear ends of the movable base, and the movable base is movably connected with the slots through the blocks, and the movable base moves up and down relative to the slots, and transverse guide rails are fixedly installed on the front and rear sides of the top of the base, and clamping assemblies are movably connected at the left and right ends of the two transverse guide rails, and oil storage pipes are fixedly installed on the front and rear sides of the inner cavity of the base, and auxiliary support assemblies are fixedly installed on the front and rear sides of the tops of the two clamping assemblies, and the left and right sides of the oil storage pipes near the bottom are fixedly connected with oil delivery pipes, and the other end of the oil delivery pipe is connected to the auxiliary support assembly.

[0007] When in use, the base needs to be installed on a transport vehicle and ensure that the device is in a horizontal position. At the same time, in the initial state, the device is in the initial state, that is, the movable base is at the highest point, and the display screen is not loaded inside the device.

[0008] As a further technical solution of the present invention, the internal movable sleeve of the oil storage tube is connected with a pressure rod, the top end of the pressure rod passes through the top end of the oil storage tube and is connected to the bottom end of the movable seat, and hydraulic oil is filled between the bottom end of the inner cavity of the oil storage tube and the bottom end of the pressure rod.

[0009] As a further technical solution of the present invention, a limit spring located inside the card slot is fixedly mounted on the bottom end of the card block, and the bottom end of the limit spring is connected to the bottom end of the inner cavity of the card slot.

[0010] In the initial state, the limit spring is in the initial state, driving the movable seat to rise, so that it is at the highest point, and the pressure rod is also at the highest point, and the hydraulic oil is basically located inside the oil storage pipe;

[0011] When the display screen needs to be transported, it can be placed on top of the movable seat. At this time, the weight of the display screen can apply downward pressure to the movable seat, that is, the limit spring is compressed, and drives the card block to move downward relative to the card slot. At this time, the movable seat moves downward and drives the pressure rod to move downward. At this time, the hydraulic oil inside the oil storage pipe is subjected to pressure and is discharged through the oil pipeline.

[0012] As a further technical solution of the present invention, the clamping assembly includes a clamping plate, and transverse clamping blocks are fixedly installed on the front and rear sides of the bottom end of the clamping plate. The transverse clamping blocks are movably connected to the transverse guide rail, and the clamping plate is displaced left and right relative to the transverse guide rail.

[0013] As a further technical solution of the present invention, a first fixed seat is fixedly installed at the bottom end of the transverse clamping block, an end of the first fixed seat away from the transverse clamping block is movably connected to a connecting rod via a rotating shaft, an end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft, and one side of the second fixed seat is connected to the movable seat.

[0014] When the movable seat moves downward, the second fixed seat moves downward accordingly, and drives the connecting rod to deflect. At this time, multiple connecting rods can deflect toward the middle of the movable seat, and at the same time apply an inward thrust to the transverse clamping block, that is, drive the two transverse clamping blocks to be relatively close. At this time, the transverse clamping block can be moved toward the direction of the movable seat under the action of the transverse guide rail, and finally drive the two splints to be relatively close and contact with the side of the LED display screen, completing the automatic clamping process.

[0015] By utilizing the placement process of the display screen, that is, the gravity of the display screen itself, the automatic descent of the movable seat is achieved through simple placement, and the automatic clamping process of the display screen is achieved through the cooperation of the clamping components. The entire process is completed automatically without manual assistance, which can effectively avoid the problem that traditional devices require the operation of the clamp to complete the clamping, thereby improving the transfer efficiency.

[0016] As a further technical solution of the present invention, the number of the auxiliary support components is four, and the auxiliary support components include a longitudinal guide rail, which is installed at the top of the splint. The four longitudinal guide rails are symmetrically installed at the top of the splint in front and back. The interior of the longitudinal guide rails is movably connected with longitudinal blocks, and the longitudinal blocks move up and down relative to the longitudinal guide rails.

[0017] As a further technical solution of the present invention, a support plate is fixedly installed on the side of the longitudinal block close to the movable seat, a third fixed seat is fixedly installed on the side of the longitudinal block away from the movable seat, the third fixed seat is movably connected to the support rod via a rotating shaft on the side away from the longitudinal block, and the fourth fixed seat is movably connected to the fourth fixed seat via a rotating shaft on the side away from the support rod.

[0018] As a further technical solution of the present invention, one end of the support rod away from the third fixed seat is movably connected to the fourth fixed seat through a rotating shaft, and the auxiliary support assembly also includes a temporary storage tube, and the outer side surface of the temporary storage tube is fixedly sleeved with a locking frame, and the locking frame is connected to one side of the machine base.

[0019] As a further technical solution of the present invention, one end of the temporary storage tube away from the movable seat is connected to the oil pipeline, a piston plate is movably sleeved inside the temporary storage tube, a piston rod is fixedly installed on the side of the piston plate close to the movable seat, the side of the piston rod away from the piston plate passes through one side of the temporary storage tube and is connected to the fourth fixed seat, and a return spring is fixedly connected between the piston plate and the temporary storage tube.

[0020] When the display screen is clamped, the movable seat moves downward, causing the hydraulic oil in the oil storage pipe to be introduced into the temporary storage pipe through the oil pipe. At this time, the piston plate is subjected to force and drives the piston rod to move in the direction close to the movable seat, that is, the return spring is stretched. At this time, the support rod is deflected obliquely upward and exerts an upward thrust on the third fixed seat, which drives the third fixed seat and the longitudinal block to move upward, and finally drives the support plate to move upward, thereby providing auxiliary support for the high side of the display screen, completing the auxiliary support process.

[0021] By reusing the placement process of the display screen, that is, completing the automatic clamping of the display screen after it is in place, the height of the support plate can be automatically adjusted to provide auxiliary support for the high position of the display screen. The whole process is completed automatically, which can effectively avoid the problem that the general clamp cannot effectively support higher display screens, and avoid the problem that the display screen is too high and falls and breaks during transportation, thereby improving the transportation quality of the display screen.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention utilizes the placement process of the display screen, that is, the gravity of the display screen itself, to achieve automatic descent of the movable seat through simple placement, and realizes the automatic clamping process of the display screen through the cooperation of the clamping assembly. The whole process is completed automatically without manual assistance, which can effectively avoid the problem that the traditional device needs to operate the clamp to complete the clamping, thereby improving the transportation efficiency.

[0024] 2. The present invention reuses the placement process of the display screen, that is, after the display screen is placed in place, the display screen is automatically clamped and the height of the support plate can be automatically adjusted to provide auxiliary support for the high position of the display screen. The whole process is completed automatically, which can effectively avoid the problem that the general clamp cannot effectively support the higher display screen, and avoid the problem that the display screen is too high and falls and breaks during transportation, thereby improving the transportation quality of the display screen.

[0036] When in use, the base 1 needs to be installed on a transport vehicle and ensure that the device is in a horizontal position. At the same time, in the initial state, the device is in the initial state, that is, the movable base 3 is at the highest point, and the device is not loaded with a display screen.

[0037] like Figure 1 and Figure 3 as well as Figure 4 and Figure 7 As shown, the internal movable sleeve of the oil storage tube 9 is connected with a pressure rod 10, the top end of the pressure rod 10 passes through the top end of the oil storage tube 9 and is connected to the bottom end of the movable seat 3, the bottom end of the inner cavity of the oil storage tube 9 and the bottom end of the pressure rod 10 are filled with hydraulic oil, and the bottom end of the clamping block 4 is fixedly installed with a limit spring 5 located inside the clamping slot 2, and the bottom end of the limit spring 5 is connected to the bottom end of the inner cavity of the clamping slot 2.

[0038] In the initial state, the limit spring 5 is in the initial state, driving the movable seat 3 to rise, so that it is at the highest point position, and the pressure rod 10 is also at the highest point position, and the hydraulic oil is basically located inside the oil storage pipe 9;

[0039] When the display screen needs to be transported, it can be placed above the movable seat 3. At this time, the weight of the display screen can apply downward pressure to the movable seat 3, that is, the limit spring 5 is compressed, and drives the block 4 to move downward relative to the slot 2. At this time, the movable seat 3 moves downward accordingly, and drives the pressure rod 10 to move downward. At this time, the hydraulic oil inside the oil storage pipe 9 is subjected to pressure and is discharged through the oil pipe 11.

[0041] Embodiment: When the movable seat 3 moves downward, the second fixed seat 702 moves downward accordingly, and drives the connecting rod 704 to deflect. At this time, multiple connecting rods 704 can deflect toward the middle of the movable seat 3, and at the same time apply an inward thrust to the transverse clamping block 703, that is, drive the two transverse clamping blocks 703 to be relatively close. At this time, the transverse clamping block 703 can be moved toward the direction of the movable seat 3 under the action of the transverse guide rail 6, and finally drive the two clamping plates 705 to be relatively close and contact with the side of the LED display screen, completing the automatic clamping process.

[0042] By utilizing the placement process of the display screen, that is, the gravity of the display screen itself, the movable seat 3 can be automatically lowered through simple placement, and the automatic clamping process of the display screen can be realized through the cooperation of the clamping assembly 7. The whole process is completed automatically without manual assistance, which can effectively avoid the problem that the traditional device needs to operate the clamp to complete the clamping, thereby improving the transportation efficiency.

[0043] like Figure 1 and Figure 6 as well as Figure 8As shown, there are four auxiliary support assemblies 8, and the auxiliary support assemblies 8 include a longitudinal guide rail 801, which is installed on the top of the clamping plate 705. The four longitudinal guide rails 801 are respectively installed on the top of the clamping plate 705 in a front-to-back symmetrical manner. The interior of the longitudinal guide rail 801 is movably connected with a longitudinal clamping block 802, and the longitudinal clamping block 802 moves up and down relative to the longitudinal guide rail 801. The side of the longitudinal clamping block 802 close to the movable seat 3 is fixedly installed with a support plate 803, and the side of the longitudinal clamping block 802 away from the movable seat 3 is fixedly installed with a third fixed seat 804, and the side of the third fixed seat 804 away from the longitudinal clamping block 802 is movably connected to the support rod 806 through a rotating shaft, and the side of the fourth fixed seat 805 away from the support rod 806 is movably connected to the fourth fixed seat 805 through a rotating shaft. The fixed seat 805 and the end of the support rod 806 away from the third fixed seat 804 are both movably connected to the fourth fixed seat 805 through a rotating shaft. The auxiliary support assembly 8 also includes a temporary storage tube 8011. The outer side surface of the temporary storage tube 8011 is fixedly sleeved with a locking frame 807, and the locking frame 807 is connected to one side of the machine base 1.

The side of the piston rod 809 away from the piston plate 808 passes through one side of the temporary storage tube 8011 and is connected to the fourth fixed seat 805. A reset spring 8010 is fixedly connected between the piston plate 808 and the temporary storage tube 8011.

[0044] Embodiment: When the display screen is clamped, the hydraulic oil in the oil storage pipe 9 is introduced into the temporary storage pipe 8011 through the oil pipe 11 due to the downward movement of the movable seat 3. At this time, the piston plate 808 is subjected to force and drives the piston rod 809 to move in the direction close to the movable seat 3, that is, the reset spring 8010 is stretched. At this time, the support rod 806 deflects obliquely upward and applies an upward thrust to the third fixed seat 804, that is, drives the third fixed seat 804 and the longitudinal block 802 to move upward, and finally drives the support plate 803 to move upward, thereby providing auxiliary support for the high side of the display screen and completing the auxiliary support process.

The entire process is completed automatically, which can effectively avoid the problem that the general clamp cannot effectively support the higher display screen, and avoid the problem that the display screen is too high and falls and breaks during transportation, thereby improving the transportation quality of the display screen.

[0046] Working principle and usage process:

[0047] When in use, the base 1 needs to be installed on a transport vehicle and ensure that the device is in a horizontal position. At the same time, in the initial state, the device is in the initial state, that is, the movable base 3 is at the highest point, and the display screen is not loaded inside the device at this time;

[0048] In the initial state, the limit spring 5 is in the initial state, driving the movable seat 3 to rise, so that it is at the highest point position, and the pressure rod 10 is also at the highest point position, and the hydraulic oil is basically located inside the oil storage pipe 9;

[0049] When the display screen needs to be transported, the display screen can be placed above the movable seat 3. At this time, the weight of the display screen can apply downward pressure to the movable seat 3, that is, the limit spring 5 is compressed, and the clamping block 4 is driven to move downward relative to the clamping slot 2. At this time, the movable seat 3 moves downward accordingly, and drives the pressure rod 10 to move downward. At this time, the hydraulic oil in the oil storage pipe 9 is subjected to pressure and is discharged through the oil delivery pipe 11.

[0050] When the movable seat 3 moves downward, the second fixed seat 702 moves downward accordingly, and drives the connecting rod 704 to deflect. At this time, the multiple connecting rods 704 can deflect toward the middle of the movable seat 3, and at the same time, apply an inward thrust to the transverse clamping block 703, that is, drive the two transverse clamping blocks 703 to move relatively close. At this time, the transverse clamping block 703 can move closer to the movable seat 3 under the action of the transverse guide rail 6, and finally drive the two clamping plates 705 to move relatively close and contact with the side of the LED display screen, completing the automatic clamping process thereof;

[0051] When the display screen is clamped, the hydraulic oil in the oil storage pipe 9 is introduced into the temporary storage pipe 8011 through the oil pipe 11 due to the downward movement of the movable seat 3. At this time, the piston plate 808 is subjected to force and drives the piston rod 809 to move in the direction close to the movable seat 3, that is, the reset spring 8010 is stretched. At this time, the support rod 806 is deflected obliquely upward and applies an upward thrust to the third fixed seat 804, that is, drives the third fixed seat 804 and the longitudinal block 802 to move upward, and finally drives the support plate 803 to move upward, thereby providing auxiliary support for the high side of the display screen, completing the auxiliary support process.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
