Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0036] In addition, the terms "first" and "second" are only used to distinguish components and cannot be understood as indicating or implying relative importance or indicating the quantity of technical features.

[0037] [First Embodiment]

[0038] As Figure 1 shown, the display splicing mechanism 100 involved in the first embodiment of the present utility model can splice and install multiple displays together to achieve the effect of multi-screen display. The display splicing mechanism 100 includes at least two wall panel components 10, at least one slender guide bar 20, and multiple hanging strip components 30. The wall panel components 10 are fixed to the wall surface, the guide bar 20 is detachably installed on the side of the wall panel components 10 away from the wall surface, and the multiple hanging strip components 30 are detachably arranged at intervals on the guide bar 20, and a display is installed on the side of the hanging strip components 30 away from the guide bar 20, so that multiple displays can be spliced.

[0039] The display splicing mechanism 100 of the present utility model can be applied to dual-screen, triple-screen, quadruple-screen or quintuple-screen displays. The present utility model will be described by taking the case of being applied to a quadruple-screen display as an example. As Figure 1 and Figure 2 shown, in the case of being used to hang a quadruple-screen display, there are three wall panel assemblies 10 and eight hanging strip components 30. That is, eight hanging strip components 30 are clamped on one side of the guide strip 20, and three wall panel assemblies 10 are hung on the other side opposite to the hanging strip components 30. The eight hanging strip components 30 are arranged in pairs as a group side by side and parallel to each other, and the three wall panel assemblies 10 are also arranged with an appropriate distance therebetween. In addition, the guide strip 20 is usually made of aluminum profile and is composed of one or more sections of aluminum profile. When composed of multiple sections, adjacent two aluminum profiles can be spliced with each other through a connecting mechanism 21 such as a connecting piece.

[0040] As Figure 3 shown, the cross-section of the guide strip 20 is in a trapezoidal structure, and a clamping groove 22 is provided on its back surface, and the clamping groove 22 is used for installing the wall panel assembly 10.

[0041] In this embodiment, the wall panel assembly 10 is fixed on the wall and has a height adjustment function and a front-back adjustment function. Please refer to Figure 4 and Figure 5 together. Specifically, each wall panel assembly 10 includes a wall panel part 11, a height adjustment part 13, a front-back adjustment part 15 and a connecting part 17. The wall panel part 11 is fixedly installed on the wall surface. The height adjustment part 13 is movably installed on the wall panel part 11 and can move up and down along the length direction of the wall panel part 11 to adjust the guide strip 20 to realize the height of the display. The front-back adjustment part 15 is movably installed on the side of the height adjustment part 13 away from the wall panel part 11 and can move back and forth along the depth direction of the wall panel part 11 to adjust the distance between the display and the wall. The connecting part 17 is installed on the side of the front-back adjustment part 15 away from the height adjustment part 13 and is used for hooking on the clamping groove 22 of the guide strip 20.

[0042] The wall panel part 11 is in a concave shape and includes a bottom plate 111 and two side plates 113 vertically connected to the two long sides of the bottom plate 111. The bottom plate 111 and the two side plates 113 cooperate with each other to form a receiving space 115 for receiving the height adjustment part 13. Fixing holes 112 are formed at the upper and lower ends of the bottom plate 111 for fixing the whole wall panel assembly 10 on the wall. A sliding groove 117 is formed on the side plate 113. In this embodiment, the upper fixing hole 112 is in a gourd shape, and the lower fixing hole 112 is a round hole or a horizontal long hole. Through the setting of the fixing holes 112, after the whole wall panel assembly 10 is fixed on the wall, it will not move upward due to the influence of external forces.

[0043] The height adjustment part 13 is movably installed between the two side plates 113, and a part of it is received in the receiving space 115. The height adjustment part 13 includes a height adjustment support plate 131, a height adjustment plate 133, and a height adjustment screw 135. The height adjustment support plate 131 is installed at the upper end of the wall panel part 11 for installing the height adjustment screw 135. The height adjustment plate 133 is in a concave shape, and it includes a back plate 1331 and two side plates 1333 perpendicularly connected to the two long sides of the back plate 1331. The side plates 1333 are arranged opposite to the side plates 113 of the wall panel part 11, that is, the side plates 1333 of the height adjustment plate 133 are located between the two side plates 113 of the wall panel part 11. At each of the upper and lower ends of each side plate 1333, a sliding piece 1334 is provided, and each sliding piece 1334 is formed by folding and extending outward from the edge of the side plate 1333 in a direction perpendicular to the side plate 1333. The sliding piece 1334 is inserted into the sliding groove 117 and can move up and down along the sliding groove 117 to realize the height adjustment function of the wall panel assembly 10. The size of the back plate 1331 is slightly smaller than the size of the bottom plate 111 of the wall panel part 11, so its two side plates 1333 can be received in the receiving space 115 formed by the wall panel part 11. In addition, openings 1339 penetrating longitudinally are provided at positions near the four corners of the back plate 1331. In addition, a fixing piece 1335 protrudes from the approximate center of the upper side of the height adjustment plate 133 toward the bottom plate 111 of the wall panel part 11. A round hole is formed in the fixing piece 1335 for the height adjustment screw 135 to pass through, and the head of the height adjustment screw 135 is fixed to the fixing piece 1335 by welding.

[0044] The height adjustment screw 135 sequentially passes through the fixing piece 1335 of the height adjustment plate 133 and the height adjustment support plate 131, and its head is fitted with the round hole in the fixing piece 1335 and welded. The height adjustment screw 135 can drive the whole height adjustment plate 133 to move toward or away from the height adjustment support plate 131. In order to position different parts of the height adjustment screw 135 on the height adjustment support plate 131 during the up and down movement, in this case, a locking nut 1351 is used to position the height adjustment screw 135. A circular groove is provided on the outer periphery of the locking nut 1351; the circular groove is stuck in the gourd hole of the height adjustment support plate 131 to install the locking nut 1351. When adjusting the height, by rotating the locking nut 1351, the height adjustment screw 135 is driven to move up and down, and then the whole height adjustment plate 133 is driven to move longitudinally relative to the wall panel part 11 to achieve the adjustment.

[0045] The front-back adjustment part 15 is movably installed on one side of the height adjustment plate 133 facing away from the wall panel part 11, and can move back and forth along the depth direction of the wall panel part 11. The front-back adjustment part 15 includes a front-back adjustment plate 151, guide pieces 153 protruding from approximately four corners of the front-back adjustment plate 151 in a direction perpendicular to the front-back adjustment plate 151, an upper front-back adjustment screw 155, and a lower front-back adjustment screw 157. The four guide pieces 153 of the front-back adjustment part 15 are respectively inserted into four openings 1339 of the height adjustment plate 133, and are connected to the side plates 1333 of the height adjustment plate 133 through connecting parts 40 such as rivets, and can move back and forth relative to the back plate 1331 of the height adjustment plate 133. The size of the front-back adjustment plate 151 is slightly smaller than the size of the back plate 1331 of the height adjustment plate 133, and it is assembled on the height adjustment plate 133 through the four guide pieces 153. Narrow and long sliding grooves 1531 are formed on each guide piece 153, and the connecting parts 40 are inserted into the sliding grooves 1531. When the front-back adjustment plate 151 is pushed towards the direction of pressing against the back plate 1331 of the height adjustment plate 133, each connecting part 40 moves from back to front in the sliding grooves 1531 of each guide piece 153, that is, moves from the direction close to the front end of the guide piece 153 to the position close to the root of the guide piece 153 in the sliding groove 1531.

[0046] As Figure 7 shown in (a) and (b) of Figure 7 (a) of Figure 5 is a schematic diagram of the wall panel assembly shown in Figure 7 when it is in the front position and the low position during the adjustment of the position. Figure 5 (b) of Figure 8 is a schematic diagram of the wall panel assembly shown in

[0047] Please refer to Figure 4 、 Figure 5 and Figure 6 together. A connection part 17 is further installed on the outer side of the front-back adjustment plate 151. The connection part 17 includes an upper connection plate 171, a lower connection plate 173, and two elastic members 175 connected between the upper connection plate 171 and the lower connection plate 173. As Figure 6As shown in the figure, the upper connecting plate 171 includes a longitudinal plate piece 1711 and a first engaging portion 1713 that are connected to each other. At the upper end of the longitudinal plate piece 1711, two safety lock pieces 1710 are provided. Along the vertical direction of the longitudinal plate piece 1711, two guiding grooves 1712 are also spaced apart. By respectively passing fasteners 18 such as M6 screws through the two guiding grooves 1712 and screwing the fasteners 18 into the front and rear adjusting plate 151, the whole upper connecting plate 171 can be fixed on the front and rear adjusting plate 151. In addition, the fasteners 18 can also move up and down in the guiding grooves 1712. The two safety lock pieces 1710 are snapped into two through holes 1510 at both ends of the front and rear adjusting plate 151. Thus, after the upper connecting plate 171 and the front and rear adjusting plate 151 are locked, a locked state is formed, which can prevent the upper connecting plate from displacing. Further, two hanging rods 1714 protrude further toward the front and rear adjusting plate 151 from both sides of the upper connecting plate 171 in a direction perpendicular to the longitudinal plate piece 1711; a notch 1715 is recessed at a substantially middle position of each hanging rod 1714. In addition, at the middle of the lower edge of the longitudinal plate piece 1711, a bent piece 1716 that extends backward and is folded downward is formed.

[0048] As Figure 5 shown in the figure, the lower connecting plate 173 includes a flat plate body 1731 and a second engaging portion 1733 that are connected to each other. A receiving groove (not marked) is formed between the second engaging portion 1733 and the flat plate body 1731 to facilitate receiving the lower end of the guide bar 20. At the upper end of the flat plate body 1731, a safety lock piece 1730 is also formed. After the safety lock piece 1730 passes through the front and rear adjusting plate 151, it is welded and fixed to the back of the front and rear adjusting plate 151. In addition, the lower edge of the flat plate body 1731 of the lower connecting plate 173 is also fixed to the front and rear adjusting plate 151 by welding. In addition, two hanging rods 1734 protrude further toward the front and rear adjusting plate 151 from both sides of the flat plate body 1731 in a direction perpendicular to the flat plate body 1731. A notch 1735 is recessed at a substantially middle position of each hanging rod 1734.

[0049] Each elastic member 175 is preferably a tension spring, and its two ends are respectively hooked in the notches 1715 of the upper connecting plate 171 and the notches 1735 of the lower connecting plate 173. In the factory state of the wall panel assembly 10, the two fasteners 18 are respectively located at the lower ends of the two guiding grooves 1712 of the upper connecting plate 171; the two elastic members 175 located between the upper connecting plate 171 and the lower connecting plate 173 are in a relatively large stretched state; in the state where the upper connecting plate 171 is buckled into the guide bar 20, the elastic members 175 are in a stretched state, thereby storing elastic potential energy.

[0050] When assembling the above wall panel assembly 10, first, pass the four guiding pieces 153 of the front and rear adjusting plate 151 through the four openings 1339 of the height adjusting plate 133 respectively, and connect the four guiding pieces 153 to the side plate 1333 of the height adjusting plate 133 through a connecting piece 40 such as a rivet, so that the connecting piece 40 can slide forward in the sliding grooves 1531 of the respective guiding pieces 153. Secondly, pass the rod portion of the upper front and rear adjusting screw 155 through the front and rear adjusting plate 151 and screw it onto the back plate of the height adjusting plate 133, and then pass the rod portion of the lower front and rear adjusting screw 157 through the front and rear adjusting plate 151 and screw it into the back plate of the height adjusting plate 133; thereafter, push the four sliding pieces 1334 on the left and right sides of the height adjusting plate 133 along the edge of the wall panel portion 11 into the sliding groove 117; again, install the locking nut 1351 on the height adjusting support plate through the calabash hole, at the same time screw the height adjusting screw 135 into the locking nut 1351, and then fix the height adjusting support plate 131 at the upper end of the wall panel portion 11, and the assembly of the wall panel assembly 10 can be completed.

[0051] The following combines Figure 9 with (a) and (b) of Figure 9 to describe the installation process of the guide bar 20 of the display splicing mechanism 100 of the present embodiment. When connecting the connecting portion 17 of the wall panel assembly 10 with the guide bar 20, first, as shown in (a) of Figure 9 , hold the guide bar 20 by hand and place it obliquely so that the gap 22 at its lower end is sleeved on the L-shaped plate body 1733 of the lower connecting plate 173; thereafter, as shown in (b) of Figure 9 , make the upper end of the guide bar 20 close to the upper connecting plate 171, and then loosen the two fasteners 18 on the upper connecting plate 171. The upper connecting plate 171 is pulled downward under the action of the elastic force of the elastic members 175 on both sides, and the two fasteners 18 move from the upper ends of the respective guide grooves 1712 to the lower ends of the respective guide grooves 1712. At this time, the upper connecting plate 171 is automatically buckled into the gap 22 at the upper part of the guide bar 20. Thereafter, re-lock the fasteners 18, and the connection between the wall panel assembly 10 and the guide bar 20 can be completed.

[0052] Please refer to Figure 10 , the hanging bar member 30 includes a hanging bar main body portion 31, a connecting rod portion 32 fixed to the inner side of the hanging bar main body portion 31, a lock member 33 movably installed on one side wall of the connecting rod portion 32, an anti-theft lock piece 34 installed on the other side wall of the connecting rod portion 32, and a padlock 35. The annular portion of the padlock 35 passes through the anti-theft lock piece 34 and one of the wing pieces 321 at the lower end of the connecting rod portion 32 at the same time, which is used to prevent criminals from removing the hanging bar member 30 from the guide bar 20 and stealing the display. The connecting rod portion 32 and the lock member 33 are oppositely arranged, and the lock member 33 can move telescopically relative to the connecting rod portion 32, so that the lock member 33 is detachably connected to the guide bar 20.

[0053] The hanging strip main body 31 is in a groove shape for connecting to the back of the display. On both sides of the lower half of the connecting rod portion 32, notches 320 are respectively recessed in the direction towards the hanging strip main body 31. The locking member 33 includes a locking piece 331 and a locking box 332. The locking piece 331 can slide up and down relative to the locking box 332 to be locked in the locking box 332 or unlocked from the locking box 332. A pull cord 36 is hung at the lower end of the locking box 332. By pulling down the pull cord 36, the locking piece 331 can be moved downward and locked in the locking box 332. At this time, the whole hanging strip component 30 can be detached from the guide strip 20. When it is necessary to fix the whole hanging strip component 30 on the guide strip 20, by pulling down the pull cord 36 again, the locking piece 331 can be disengaged from the engaging portion (not shown in the figure) in the locking box 332 and spring upward, so that the side of the locking piece 331 abuts against the back of the guide strip 20 to lock the hanging strip component 30 on the guide strip 20.

[0054] Please refer to Figure 11 , Figure 11 is a schematic diagram of the mating relationship between the guide strip 20 involved in the first embodiment and the connecting portions of the hanging strip components 30 and the wall panel assembly 10 on both sides thereof. As Figure 11 shown, since there is a gap between the locking piece 331 of the hanging strip component 30 and the bottom surface of the lower connecting plate 173 of the wall panel assembly 10, it will not hinder the left and right movement of the hanging strip component 30; in addition, the lower end of the guide strip 20 is in a shape composed of a straight line and an arc, rather than a slant structure, so the effective contact area between the guide strip 20 and the locking piece 331 is increased, and thus the hanging strip component 30 can be effectively locked; in addition, since the connecting rod portion 32 is provided with notches 320, the connecting rod portion 32 can avoid the connecting mechanism 21 of the guide strip 20, and further the left and right movement of the hanging strip component 30 is not interfered.

[0055] [Second Embodiment]

[0056] Next, the display splicing mechanism 200 involved in the second embodiment of the present utility model will be described in conjunction with Figures 12 to 17 In the following description, the same symbols are marked for components with the same structure, and their detailed descriptions are omitted. Specifically, since the structure of the guide strip 20 of the display splicing mechanism 200 and the specific structures of the wall panel portion 11, the height adjustment portion 13, and the front and rear adjustment portion 15 of the wall panel assembly 10a, as well as the front and rear and up and down adjustment principles are the same, the relevant descriptions are omitted, and only the differences between the connecting portion 17a of the hanging strip component 30a and the wall panel assembly 10a in the second embodiment and those in the first embodiment will be described.

[0057] Figure 12 Schematically shows the mating relationship between the wall panel assembly 10a and the guide strip 20 in the second embodiment. Figure 13(a) shows the state of the wall panel assembly 10a of the second embodiment when viewed from the left front. Figure 13 (b) shows the state of the wall panel assembly 10a of the second embodiment when viewed from the right rear.

[0058] From Figure 12 and Figure 13 It can be seen that the structures of the upper connecting plate 171a and the lower connecting plate 173a of the connecting portion 17a of the wall panel assembly 10a are significantly different from those of the first embodiment. Specifically, a safety lock piece 1710 is not formed at the upper end of the upper connecting plate 171a. The upper end of the upper connecting plate 171a of the second embodiment is fixed to the front and rear adjusting plate 151 by two screws. In addition, a hanging rod 1714 protruding toward the front and rear adjusting plate 151 is not formed on the side of the upper connecting plate 171a, while in the second embodiment, a hook handle 176 is formed on the outer side wall of the bent piece 1716 of the upper connecting plate 171a. A hanging rod 1735 protruding toward the front and rear adjusting plate 151 is not formed on the side of the lower connecting plate 173a, while in the second embodiment, a safety lock piece 1730 protruding toward the wall panel portion is formed on the back of the lower connecting plate 173a, and a fixing hole (not marked) is formed on the safety lock piece 1730. Thus, both ends of the elastic member 175 are respectively hooked in the hook handle 176 and the fixing hole, and the elastic member 175 cannot be seen from the front or side of the wall panel assembly 10a, that is, the elastic member 175 is hidden behind the front and rear adjusting plate 151. In this way, it is more beneficial to prevent the elastic member 175 from being damaged by external force collision.

[0059] Figure 14 Shows the disassembly process of the guide bar 20 of the display splicing mechanism 200 of the second embodiment relative to the wall panel assembly 10a. As Figure 14 shown in (a), when the guide bar 20 is to be removed from the wall panel assembly 10a, first, remove the screws on the upper connecting plate 171a, loosen the fastener 18, and then lift the guide bar 20 upward. By the guide bar 20 pushing the upper connecting plate 171a upward, the fastener 18 moves upward in the guide groove 1712 of the upper connecting plate 171a. At this time, the elastic member 175 is stretched. Finally, move the lower part of the guide bar 20 outward to remove the guide bar 20.

[0060] In addition, the installation process of the guide bar 20 relative to the wall panel assembly 10a in the second embodiment is similar to that of the first embodiment, and will not be elaborated here. Figure 15 (a) shows the overall structure of the hanging bar component 30a in the second embodiment. Figure 15 (b) is a three-dimensional enlarged schematic diagram of the lock component 37 of the hanging bar component 30a. The main difference between the hanging bar component 30a in the second embodiment and the hanging bar component 30 in the first embodiment lies in: the specific structure and action principle of the lock component 37 are different.

[0061] Please referFigure 16 , the latch member 37 mainly includes a frame portion 370, an elastic member 373, and a hanging rod 375. A notch (not marked) for the pulling rope 36 is formed at the upper end of the frame portion 370. A hanging rod 375 is connected to the lower edge of one of the side plates of the frame portion 370. The hanging rod 375 extends obliquely downward and is connected to the one side plate at an obtuse angle. Sliding grooves 3701 are correspondingly formed in two left and right opposite side plates of the frame portion 370, and a pair of hooks 3703 are formed. The whole of the frame portion 370 is fixed in the space between two fins 321 at the lower end of the connecting rod portion 32 by two rivets 3705 passing through the sliding grooves 3701. One end of the elastic member 373 is hooked on the hooking portion 323 formed at the lower end of the connecting rod portion 32, and the other end of the elastic member 373 is hooked in a through hole formed at the front end of the hanging rod 375, so as to be connected between the latch member 37 and the connecting rod portion 32 in an inclined state.

[0062] Please refer to Figure 17 , Figure 17 The (a) of Figure 15 is a partially enlarged schematic view of the latch member 37 shown in the figure in a locked state relative to the hanging strip member 30a. Figure 17 The (b) of Figure 15 is a partially enlarged schematic view of the latch member 37 shown in the figure in an unlocked state relative to the hanging strip member 30a. In the locked state, as shown in the (a) of Figure 15 , the whole of the latch member 37 is in a vertically standing state, that is, it is completely received in the space between two left and right fins 321 at the lower end of the connecting rod portion 32. At this time, the hook 3703 abuts against the back surface of the guide bar 20, and the rivet 3705 moves to the lowermost end of the sliding groove 3701; in the unlocked state, the latch member 37 is in an inclined state relative to the hanging strip main body portion 31, that is, the hook 3703 at its upper end protrudes outward from the space between two left and right fins 321 of the connecting rod portion 32, so as to facilitate removing the hanging strip member 30 from the guide bar 20.

[0063] In summary, the display splicing mechanism involved in the present utility model can splice multiple displays together horizontally and fix them on the wall, and can be adjusted up and down and back and forth within a certain range. The height adjustment and back-and-forth adjustment functions of the display splicing mechanism are integrated in the wall panel assembly. In addition, the installation structure of the wall panel assembly of the present utility model relative to the guide bar is simpler, the installation effect is more reliable, and since elastic members are hung on both sides of the upper and lower connecting plates, the upper connecting plate can be automatically buckled into the gap on the back of the guide bar by the elastic force of the elastic members, so it is convenient for a single person to install the guide bar on the wall panel assembly, and the operation is simpler. In addition, the latch member of the hanging strip member of the present utility model realizes the locking or unlocking action of the hanging strip member relative to the guide bar by pulling the pulling rope, and the operation is simpler and more convenient.
