Preferably, the form of flipping includes at least one of the following: flipping from the upper edge of the spliced display device, flipping from the side edge of the spliced display device, flipping from the inside of the spliced display device, and flipping from below the spliced display device.
该纵向传动装置12,用于使拆装装置20在拼接显示装置纵向移动。该纵向传动装置12包括:索轨121和牵拉装置122。该索轨121储存在该索轨储蓄箱1112中,并由天车根据控制装置50的控制指令驱动索轨的收放。可以无障碍地从该索轨储蓄箱1112收放,依次穿过该第一滑动机构11141和第二滑动机构11153,与该牵引装置122连接。该牵引装置122,安装于索轨121的一端部,用于与钢结构底部预留的固定端相配合,从而使该索轨121绷直。The longitudinal transmission device 12 is used to move the disassembly and assembly device 20 in the longitudinal direction of the splicing display device. The longitudinal transmission device 12 includes a cable rail 121 and a pulling device 122. The cable rail 121 is stored in the cable rail storage box 1112, and the overhead crane drives the cable rail to be retracted and retracted according to the control command of the control device 50. It can be retracted from the cable rail storage box 1112 without obstacles, passes through the first sliding mechanism 11141 and the second sliding mechanism 11153 in sequence, and is connected to the traction device 122. The traction device 122 is installed at one end of the cable rail 121 and is used to cooperate with the fixed end reserved at the bottom of the steel structure, so that the cable rail 121 is stretched straight.
该索轨121与拆装装置20稳定啮合,使拆装装置20稳定地固定啮合于索轨121上。其啮合形式为索轨121与拆装装置的轮啮合,其形式包括但不限于齿形轮、螺纹轮、平轮等,啮合使得拆装装置20能够稳定固定在索轨121上,同时支持拆装装置20在索轨上的移动,其移动包括爬升和下降过程。The cable rail 121 is stably engaged with the assembling and disassembling device 20, so that the assembling and disassembling device 20 is stably fixed and engaged on the cable rail 121. The meshing form is that the cable rail 121 meshes with the wheels of the dismounting device, and its forms include but not limited to toothed wheels, threaded wheels, flat wheels, etc. The meshing enables the dismounting device 20 to be stably fixed on the cable rail 121 while supporting disassembly. The movement of the mounting device 20 on the cable track includes climbing and descending processes.
在使拆装装置20翻越至拼接显示装置前方的过程中,通过控制安装于天车四周之上的若干升降臂的升降,将悬臂装置抬升至一定高度,使得悬臂装置牵拉的拆装装置高出拼接显示装置。此时,如果悬臂装置的悬臂杆向前倾斜,就可以使拆装装置移动到拼接显示装置前方;如果悬臂杆向后倾斜,就可以使拆装装置移动至拼接显示装置后方。In the process of turning the disassembly and assembly device 20 to the front of the splicing display device, the cantilever device is raised to a certain height by controlling the lifting of several lifting arms installed on the circumference of the overhead crane, so that the disassembly and assembly device pulled by the cantilever device is high Out splicing display device. At this time, if the cantilever rod of the cantilever device is tilted forward, the disassembly and assembly device can be moved to the front of the splicing display device; if the cantilever rod is tilted backward, the disassembly and assembly device can be moved to the rear of the splicing display device.
在拆装装置翻越至拼接显示装置前方时,天车根据控制装置50的控制指令控制索轨储蓄箱中的索轨不断地放长,使得啮合在索轨的拆装装置由于索轨不断地变长而不断地下降,在索轨降至屏体下边沿时,安装于索轨端部的牵引装置与钢结构底部预留的固定端相配合,从而将索轨绷直,索轨绷直后,检测装置和拆装装置才会进行下一步的工作。此时,使索轨绷直的力并不需要很大,仅保证索轨不会因外界环境做一定幅度的摆动即可,在拆装装置吸附与拼接显示装置上时,其吸附力也能较轻易的克服绷直索轨带来的拉力。When the disassembling and assembling device overturns to the front of the splicing display device, the overhead crane controls the cable rail in the cable rail storage box to continuously lengthen according to the control instruction of the control device 50, so that the disassembling and assembling device engaged with the cable rail is constantly changing due to the cable rail Long and continuous descending. When the cable track is lowered to the bottom edge of the screen, the traction device installed at the end of the cable track matches the fixed end reserved at the bottom of the steel structure to stretch the cable track straight. , The detection device and disassembly device will proceed to the next step. At this time, the force to straighten the cable rail does not need to be great, just ensure that the cable rail does not swing to a certain extent due to the external environment. When the disassembly device is adsorbed on the splicing display device, its adsorption force can also be higher. Easily overcome the tension caused by the straight cable track.
在需要拆装装置隐藏至拼接显示装置后方时,天车根据控制装置50的控制指令控制索轨储蓄箱中的索轨先放长一小段,使得牵引装置与钢结构的卡紧结构松开,然后控制索轨不断地收缩,使得啮合在索轨的拆装装置由于索轨不断地变短而不断地上升。在拆装装置上升到高出拼接显示装置后,控制悬臂杆向后倾斜,使拆装装置移动至拼接显示装置后方,再控制安装于天车四周之上的若干升降臂的升降,使悬臂装置1115牵拉的拆装装置隐藏至拼接显示装置后方。When the disassembly and assembly device needs to be hidden behind the splicing display device, the overhead crane controls the cable rail in the cable rail storage box to lengthen a short length according to the control instruction of the control device 50, so that the traction device and the clamping structure of the steel structure are loosened. Then the control cable track is continuously contracted, so that the disassembly and assembly device engaged in the cable track continuously rises due to the continuous shortening of the cable track. After the disassembly and assembly device rises above the splicing display device, control the cantilever rod to tilt backward to move the disassembly and assembly device to the rear of the splicing display device, and then control the lifting and lowering of several lifting arms installed around the overhead crane to make the cantilever device The disassembly and assembly device pulled by 1115 is hidden behind the splicing display device.
进一步地,在钢结构底部预留的固定端即在屏体下沿索轨端部卡口位置是安置在一条导轨上的,以此来使得天车进行横向移动时,索轨整体也能随之进行横向移动。优选地,该固定端可以通过钩锁、电磁等形式进行锁紧操作。Further, the fixed end reserved at the bottom of the steel structure, that is, the bayonet position along the end of the cable rail under the screen, is arranged on a guide rail, so that when the overhead crane moves laterally, the cable rail as a whole can follow. It moves laterally. Preferably, the fixed end can be locked by hook lock, electromagnetic or other forms.
在传动装置的传动过程中,以面向拼接显示装置横向为X轴、纵向为Y轴、高度为Z轴,则天车为解决拆装装置的X轴位移工作,索轨为解决拆装装置的Y轴位移工作,悬臂杆解决拆装装置和检测装置的Z轴位移工作。这样,则不同轴的移动控制,是以不同的结构工作来区分的。X轴的移动控制,是通过天车横向运行来提供的,此时天车驱动装置的工作和减速机的工作,是控制移动精度的关键,而保证天车的移动距离能否准确,则是保证了传动装置在X轴方向上的移动准确。In the transmission process of the transmission device, the horizontal direction of the spliced display device is the X axis, the vertical direction is the Y axis, and the height is the Z axis. Then the crane is to solve the X-axis displacement of the disassembly device, and the cable rail is to solve the disassembly device. Y-axis displacement work, the cantilever rod solves the Z-axis displacement work of the disassembly device and the detection device. In this way, the movement control of different axes is distinguished by different structures. The movement control of the X-axis is provided by the horizontal movement of the crane. At this time, the work of the crane drive device and the work of the reducer are the keys to control the accuracy of the movement. It is necessary to ensure the accuracy of the movement distance of the crane. Ensure that the transmission device moves accurately in the X-axis direction.

优选地,该升降承接板213采用包括以下之一实现电磁弹簧卡锁211的升降操作:使用升降杆、丝杆、电磁吸附、绳索牵拉。当电磁弹簧卡锁211被收至拆装装置20内时,该升降弹簧214处于受压状态,提供反作用力,拆装装置20克服升降弹簧214带来的反作用力,完成对拆装装置20的抬升,抬升的目的是为了使电磁弹簧卡锁211与显示单元方钢830的预留孔832进行对齐,在抬升力消失后,电磁弹簧卡锁211能够直接且迅速的卡入预留孔832中,实现显示单元的定位安装。Preferably, the lifting receiving plate 213 adopts one of the following to realize the lifting operation of the electromagnetic spring latch 211: using lifting rods, screw rods, electromagnetic adsorption, and rope pulling. When the electromagnetic spring latch 211 is received into the disassembly device 20, the lifting spring 214 is in a compressed state and provides a reaction force. The disassembly device 20 overcomes the reaction force brought by the lifting spring 214 to complete the disassembly device 20 The purpose of lifting is to align the electromagnetic spring latch 211 with the reserved hole 832 of the square steel 830 of the display unit. After the lifting force disappears, the electromagnetic spring latch 211 can be directly and quickly snapped into the reserved hole 832 , Realize the positioning installation of the display unit.

该控制对接螺柱216,用于与控制装置50配合,接收控制装置50发送的控制信号,实现对电磁弹簧卡锁211的控制。具体过程为:在将电磁弹簧卡锁211插入方钢830的预留孔832中时,电磁弹簧卡锁211在插入过程中受到电磁吸附力作用,其卡板会收缩至小于孔径位置,当穿过预留孔832后,电磁线圈断电,磁性消失,卡板受弹簧弹力作用伸张至孔径外,实现将显示单元固定在装夹固定结构上,完成对显示单元的固定。The control docking stud 216 is used to cooperate with the control device 50 to receive the control signal sent by the control device 50 to realize the control of the electromagnetic spring latch 211. The specific process is: when the electromagnetic spring latch 211 is inserted into the reserved hole 832 of the square steel 830, the electromagnetic spring latch 211 is subjected to electromagnetic adsorption force during the insertion process, and the clamp plate will shrink to a position smaller than the aperture. After passing through the reserved hole 832, the electromagnetic coil is de-energized, the magnetism disappears, and the card plate is stretched out of the aperture by the elastic force of the spring, so that the display unit is fixed on the clamping and fixing structure, and the fixing of the display unit is completed.

如图8至图11所示,为电磁弹簧卡锁结构示意。该电磁弹簧卡锁211包括:定位螺柱2111、顶壳2112、电磁线圈2113、铁芯2114、伸缩架底座2115、伸缩架2116、弹簧2117、卡板2118、底壳2119。As shown in Fig. 8 to Fig. 11, a schematic diagram of the electromagnetic spring locking structure. The electromagnetic spring latch 211 includes a positioning stud 2111, a top shell 2112, an electromagnetic coil 2113, an iron core 2114, a telescopic frame base 2115, a telescopic frame 2116, a spring 2117, a clamping plate 2118, and a bottom shell 2119.
该定位螺柱2111位于该电磁弹簧卡锁211的顶部,旋入升降承接板213中进行定位配合,使得该电磁弹簧卡锁211能随着升降承接板213的升降而升降。The positioning stud 2111 is located on the top of the electromagnetic spring latch 211 and is screwed into the lifting receiving plate 213 for positioning cooperation, so that the electromagnetic spring latch 211 can rise and fall with the lifting of the lifting receiving plate 213.
该顶壳2112,用于在装夹定位过程中,与显示单元上的方钢830的预留孔832相配合。The top shell 2112 is used to match the reserved hole 832 of the square steel 830 on the display unit during the clamping and positioning process.
该铁芯2114,衔接在该顶壳2112的下方,用于缠绕该电磁线圈2113,通电时使该电磁线圈2113能够产生电磁吸附力。The iron core 2114 is connected under the top case 2112 and is used to wind the electromagnetic coil 2113 so that the electromagnetic coil 2113 can generate electromagnetic attraction force when it is energized.
该伸缩架2116与该弹簧2117配合,能够将卡板2118迅速向外推,完成张开动作。The telescopic frame 2116 cooperates with the spring 2117 to quickly push the card board 2118 outward to complete the opening action.
该伸缩架底座2115,位于该铁芯2114外部,为伸缩架2116提供支承。The telescopic frame base 2115 is located outside the iron core 2114 and provides support for the telescopic frame 2116.
该卡板2118嵌套在该电磁弹簧卡锁211的端部,在伸出时能够与显示单元后端的方钢830配合,实现装夹固定。The card board 2118 is nested on the end of the electromagnetic spring lock 211, and when extended, it can cooperate with the square steel 830 at the rear end of the display unit to achieve clamping and fixing.
该底壳2119,用于在装夹过程中为伸缩架底座2115提供一个支承力,防止装夹过程中该伸缩架2116及伸缩架底座2115的断裂。The bottom shell 2119 is used to provide a supporting force for the telescopic frame base 2115 during the clamping process, so as to prevent the telescopic frame 2116 and the telescopic frame base 2115 from being broken during the clamping process.
具体地,该电磁弹簧卡锁211存在两种状态:收缩状态和张开状态。这两种状态的区别在于所述卡板2118的收缩与张开。如图8与图9所示电磁弹簧卡锁211处于收缩状态,即所述卡板2118收缩至电磁弹簧卡锁211整体尺寸之内;图10和图11所示为电磁弹簧卡锁的张开状态,即卡板2118张开至电磁弹簧卡锁211整体尺寸之外,此时卡板2118突出部分一半会承接方钢面,将整个显示单元托起或者对显示单元进行定位。Specifically, the electromagnetic spring latch 211 has two states: a contracted state and an expanded state. The difference between these two states lies in the contraction and expansion of the card board 2118. As shown in Figure 8 and Figure 9, the electromagnetic spring lock 211 is in a contracted state, that is, the card plate 2118 is contracted to within the overall size of the electromagnetic spring lock 211; Figures 10 and 11 show the opening of the electromagnetic spring lock State, that is, the card board 2118 is expanded beyond the overall size of the electromagnetic spring latch 211. At this time, half of the protruding part of the card board 2118 will accept the square steel surface to hold up the entire display unit or position the display unit.
具体地,所述电磁弹簧卡锁211的收缩与张开取决于是否对所述电磁线圈2113通电,当对电磁线圈2113进行通电时,电磁线圈2113中会产生强大的电磁吸附力,卡板2118受电磁吸力作用收缩,此时,该卡板2118收缩至电磁弹簧卡锁211整体尺寸之内,使得该电磁弹簧卡锁211脱离显示单元的方钢预留孔,实现将显示单元从装夹固定结构上拆卸,完成对显示单元的拆卸。当对电磁线圈2113进行断电时,所述弹簧2117的弹力能够将卡板2118迅速向外推,完成张开动作,使卡板2118张开至电磁弹簧卡锁211整体尺寸之外,此时卡板2118突出部分一半会承接方钢面,将整个显示单元托起或者对显示单元进行定位,实现将显示单元固定在装夹固定结构上,完成对显示单元的固定。Specifically, the contraction and expansion of the electromagnetic spring latch 211 depends on whether the electromagnetic coil 2113 is energized. When the electromagnetic coil 2113 is energized, a strong electromagnetic adsorption force is generated in the electromagnetic coil 2113, and the clamping plate 2118 Contracted by the electromagnetic attraction, at this time, the card plate 2118 shrinks to within the overall size of the electromagnetic spring lock 211, so that the electromagnetic spring lock 211 is separated from the square steel reserved hole of the display unit, and the display unit is fixed from the clamp The structure is disassembled to complete the disassembly of the display unit. When the electromagnetic coil 2113 is de-energized, the elastic force of the spring 2117 can quickly push the card plate 2118 outwards to complete the opening action, so that the card plate 2118 is expanded beyond the overall size of the electromagnetic spring lock 211. At this time, Half of the protruding part of the card board 2118 will accept the square steel surface, hold up the entire display unit or position the display unit, so that the display unit is fixed on the clamping and fixing structure, and the fixing of the display unit is completed.

如图3所示。该解锁机构23,设置在吸附装置22上,具体位置是设置在伸缩装置221的X型伸缩臂2211的各个顶端。该解锁机构23包括解锁插针231、伸缩机构(未图示)、旋转电机(未图示)。其中,该解锁插针231,容纳于伸缩机构中,用于插入显示单元的解锁孔820中,将显示单元从钢结构上解锁。该伸缩机构,可根据控制装置50的指令进行伸缩,在解锁时,向外伸出,解锁完成后,向内收缩。该旋转电机,用于驱动解锁插针231按预设方向旋转,使解锁插针231从解锁孔820中抽出。优选地,该预设方向为逆时针方向,该旋转电机驱动解锁插针231按逆时针方向旋转,使解锁插针231从解锁孔820中抽出。As shown in Figure 3. The unlocking mechanism 23 is set on the suction device 22, and the specific position is set on each top end of the X-shaped telescopic arm 2211 of the telescopic device 221. The unlocking mechanism 23 includes an unlocking pin 231, a telescopic mechanism (not shown), and a rotating electric machine (not shown). Wherein, the unlocking pin 231 is accommodated in the telescopic mechanism, and is used for inserting into the unlocking hole 820 of the display unit to unlock the display unit from the steel structure. The telescopic mechanism can expand and contract according to the instructions of the control device 50, when unlocking, it extends outwards, and after unlocking is completed, it contracts inwards. The rotating motor is used to drive the unlocking pin 231 to rotate in a preset direction, so that the unlocking pin 231 is drawn out from the unlocking hole 820. Preferably, the preset direction is a counterclockwise direction, and the rotating motor drives the unlocking pin 231 to rotate in a counterclockwise direction, so that the unlocking pin 231 is withdrawn from the unlocking hole 820.
在本申请实施例中,在钢结构上设置用于锁扣固定每个显示单元的锁扣机构。在显示单元中,在显示单元前面的四周位置上预设有若干个与上述锁扣机构匹配的解锁孔820(例如4个解锁孔),通过将解锁插针插入该解锁孔820,即可将显示单元从钢结构的锁扣机构中解锁。优选地,在显示单元前面的四角预设有4干个解锁孔820,每个解锁孔的孔径大小为2mm。In the embodiment of the present application, a locking mechanism for locking each display unit is provided on the steel structure. In the display unit, a number of unlocking holes 820 (for example, 4 unlocking holes) matching the above-mentioned locking mechanism are preset on the surrounding positions in the front of the display unit. By inserting the unlocking pin into the unlocking hole 820, you can insert the unlocking pin into the unlocking hole 820. The display unit is unlocked from the locking mechanism of the steel structure. Preferably, four unlocking holes 820 are preset in the four corners of the front of the display unit, and the aperture size of each unlocking hole is 2 mm.
该解锁插针231设置在吸附装置22上,具体位置是设置在伸缩装置221的X型伸缩臂2211的各个顶端上,与显示单元的解锁孔位置相匹配。该解锁插针231的轴径等于或略小于显示单元解锁孔820的孔径,解锁插针231的数量与解锁孔820的数量相匹配。The unlocking pin 231 is arranged on the suction device 22, and the specific position is arranged on each top end of the X-shaped telescopic arm 2211 of the telescopic device 221, which matches the position of the unlocking hole of the display unit. The shaft diameter of the unlocking pin 231 is equal to or slightly smaller than the aperture of the unlocking hole 820 of the display unit, and the number of the unlocking pin 231 matches the number of the unlocking hole 820.
在需要将显示单元解锁时,经过定位装置对解锁插针进行定位后,伸缩机构根据控制装置的指令向外伸出,从而使得解锁插针插入对应的解锁孔中,即可将显示单元从钢结构的锁扣机构中解锁。此时,通过解锁插针与解锁孔配合的力将显示单元缓缓拉出,因拆装装置的装夹固定结构的边框内侧边缘预留有相应的导向滑轨,使得显示单元能够以较小的阻力在Z轴方向上将显示单元拉出,故解锁插针与解锁孔的配合力即能够将显示单元拉出。显示单元拉出至拆装装置上后,拆装装置中的电磁弹簧卡锁插入显示单元方钢上的预留孔,在将电磁弹簧卡锁插入方钢的预留孔中时,电磁弹簧卡锁在插入过程中受到电磁吸附力作用,其卡板会收缩至小于孔径位置,当穿过预留孔后,电磁线圈断电,磁性消失,卡板受弹簧弹力作用伸张至孔径外,卡板突出部分一半会承接显示单元方钢面,将整个显示单元托起或者对显示单元进行定位,实现将显示单元固定在装夹固定结构上,完成对显示单元的固定。此时,吸附装置的永磁体与显示单元的表面轻轻接触,由于永磁体的磁性较弱,使得永磁体与显示单元中的拼接显示装置表面接触的力不是很大,使得显示单元与吸附装置缓慢接触,为电磁体的强力吸附起到缓冲作用,不会损坏显示单元中的拼接显示装置,在永磁体接触显示单元表面后,电磁体通电吸附显示单元,从而使吸附装置与显示单元相互配合,配合完成后,显示单元则被固定吸附在拆装装置的吸附装置上。此时,控制装置控制旋转电机驱动解锁插针逆时针旋转,以及控制伸缩机构向内收缩,将解锁插针从解锁孔中抽出。此时显示单元整个拆卸过程完成。When the display unit needs to be unlocked, after the unlocking pin is positioned by the positioning device, the telescopic mechanism extends outward according to the instruction of the control device, so that the unlocking pin is inserted into the corresponding unlocking hole, and the display unit can be removed from the steel The structure is unlocked in the locking mechanism. At this time, the display unit is slowly pulled out by the force of the unlocking pin and the unlocking hole. Because the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is reserved with a corresponding guide rail, the display unit can be smaller The resistance of φ pulls the display unit out in the Z-axis direction, so the matching force of the unlocking pin and the unlocking hole can pull the display unit out. After the display unit is pulled out to the disassembly device, the electromagnetic spring lock in the disassembly device is inserted into the reserved hole on the square steel of the display unit. When the electromagnetic spring lock is inserted into the reserved hole of the square steel, the electromagnetic spring locks When the lock is inserted by the electromagnetic attraction force, its card board will shrink to a position smaller than the aperture. After passing through the reserved hole, the electromagnetic coil will be de-energized and the magnetism will disappear. The card board will be stretched out of the aperture by the spring force. Half of the protruding part will accept the square steel surface of the display unit, hold up the entire display unit or position the display unit, and realize the fixation of the display unit on the clamping and fixing structure to complete the fixation of the display unit. At this time, the permanent magnet of the adsorption device is in light contact with the surface of the display unit. Due to the weak magnetism of the permanent magnet, the force of the permanent magnet in contact with the surface of the spliced display device in the display unit is not very large, so that the display unit and the adsorption device Slow contact is a buffer for the strong adsorption of the electromagnet, and will not damage the spliced display device in the display unit. After the permanent magnet touches the surface of the display unit, the electromagnet is energized to adsorb the display unit, so that the adsorption device and the display unit cooperate with each other , After the matching is completed, the display unit is fixedly adsorbed on the suction device of the disassembly and assembly device. At this time, the control device controls the rotating motor to drive the unlocking pin to rotate counterclockwise, and controls the telescopic mechanism to contract inward, so as to withdraw the unlocking pin from the unlocking hole. At this point, the entire disassembly process of the display unit is completed.
在需要将显示单元安装时,经过定位装置对钢结构的锁扣机构进行定位后,确认需要安装的位置。吸附装置吸附需要安装的显示单元,由传送装置移动至经过定位的钢结构安装位置。到达安装位置后,电磁弹簧卡锁的电磁线圈进行通电时,电磁线圈产生强大的电磁吸附力,使卡板受电磁吸力作用收缩至电磁弹簧卡锁整体尺寸之内,使得该电磁弹簧卡锁脱离显示单元的方钢预留孔,使电磁弹簧卡锁从显示单元中抽出,实现将显示单元从装夹固定结构上拆卸,完成对显示单元的拆卸。此时,因拆装装置的装夹固定结构的边框内侧边缘预留有相应的导向滑轨,显示单元可以沿着导向滑轨滑入钢结构的安装位置,显示单元上对应卡锁与钢结构的锁扣机构配合,完成显示单元在钢结构上的安装。When the display unit needs to be installed, after the locking mechanism of the steel structure is positioned by the positioning device, the position to be installed is confirmed. The adsorption device adsorbs the display unit that needs to be installed, and is moved by the conveying device to the positioned steel structure installation position. After reaching the installation position, when the electromagnetic coil of the electromagnetic spring lock is energized, the electromagnetic coil generates a strong electromagnetic attraction force, which causes the card plate to shrink to within the overall size of the electromagnetic spring lock by the electromagnetic attraction force, so that the electromagnetic spring lock is separated The square steel reserved hole of the display unit allows the electromagnetic spring latch to be withdrawn from the display unit, so that the display unit can be disassembled from the clamping and fixing structure, and the disassembly of the display unit is completed. At this time, because the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is reserved with corresponding guide rails, the display unit can be slid into the installation position of the steel structure along the guide rails, and the corresponding latch and steel structure on the display unit The locking mechanism cooperates to complete the installation of the display unit on the steel structure.
