Description

Technical Field

[0001] This utility model relates to the field of display screen assembly technology, and in particular to an installation device and an LED display screen. Background Technology

[0002] In a small-pitch LED display, there are display modules and a cabinet. The display modules are connected to the cabinet by a magnetic adsorption structure to install and fix the display modules. The two are assembled to form an LED display.

[0003] When installing the display module from the front of the cabinet, the module must be aligned with the side of the cabinet for accurate installation. During this process, the display module is tilted, and the LED beads at the edges are easily squeezed, causing damage. When installing the display module from the rear of the cabinet, the installer's view is mostly obstructed by the cabinet structure, making it difficult to find the correct assembly position of the display module. The same problem occurs, leading to damage to the display module. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of how to align and install the display module and the cabinet.

[0005] To solve the above-mentioned technical problems, this utility model provides an installation device for installing a display module and a housing, the installation device comprising:

[0006] The cylindrical body has a hollow interior forming a first guide channel, and the cylindrical body is used to be installed and fixed onto the box body;

[0007] A guide rod is inserted into the first guide channel. The guide rod is movable relative to the cylinder to have a switchable locked state and an unlocked state. When the guide rod is in the unlocked state, it is movable along the first guide channel of the cylinder. When the guide rod is in the locked state, it is fixed to the cylinder.

[0008] The guide rod has a first end and a second end, the first end facing the display module and used for detachable connection to the back of the display module; when an external force is applied to the second end of the guide rod, the guide rod can be switched from a locked state to an unlocked state.

[0009] When the first end is connected to the display module, the guide rod can drive the display module to move into the housing along the axial direction of the first guide channel of the cylinder, the guide rod is locked to the cylinder, and the display module is fixed in the housing; when an external force is applied to the second end of the guide rod, the guide rod is unlocked from the cylinder, and the display module can move out of the housing along the axial direction of the first guide channel.

[0010] In one exemplary embodiment of this disclosure, the guide rod has mounting holes on its outer peripheral wall;

[0011] The mounting device further includes a locking assembly, which includes an elastic element and a ball movably disposed in the mounting hole. One end of the elastic element is connected to the guide rod, and the other end of the elastic element acts on the ball so that the ball can move toward the direction of the cylinder.

[0012] The cylinder is provided with a locking position that restricts the movement of the ball along the axial direction of the cylinder. When the guide rod is in the locked state, the elastic element abuts against the ball and causes the ball to be engaged with the locking position. When the guide rod is in the unlocked state, the ball and the locking position are released, and the guide rod can move along the first guide channel.

[0013] In one exemplary embodiment of this disclosure, the guide rod includes a rod body and a locking handle connected to one end of the rod body. The rod body passes through a first guide channel, and the end of the rod body opposite to the locking handle constitutes the first end of the guide rod. The mounting hole is formed on the outer peripheral wall of the rod body. The rod body has a second guide channel along its own axial direction, and the mounting hole communicates with the second guide channel. The locking handle is movably inserted into the second guide channel, and the end of the locking handle opposite to the rod body constitutes the second end.

[0014] The lock handle includes a large-diameter section and a small-diameter section arranged coaxially. One end of the small-diameter section extends out of the second guide channel. When the guide rod is in the unlocked state, the outer wall of the small-diameter section abuts against the ball. When the guide rod is in the locked state, the outer wall of the large-diameter section abuts against the ball.

[0015] The elastic element is disposed in the second guide channel. One end of the elastic element is connected to the inner wall of the second guide channel, and the other end of the elastic element is connected to one end of the large diameter section. A force is applied to the large diameter section to move it away from the first end, so that the large diameter section can push the ball out to the locking position.

[0016] In one exemplary embodiment of this disclosure, the lock handle further includes a connecting section, the two ends of which are respectively connected to the large-diameter section and the small-diameter section, and the diameter of the connecting section gradually decreases in the direction from the large-diameter section to the small-diameter section.

[0017] In one exemplary embodiment of this disclosure, the rod includes a first segment and a second segment coaxially arranged, the second segment being away from the first end relative to the first segment, the inner diameter of the first segment matching the outer diameter of the larger diameter segment, the inner diameter of the second segment matching the outer diameter of the smaller diameter segment, the second segment protruding inward relative to the first segment to form a stop portion, and the connecting segment being able to abut against the stop portion to restrict the lock handle from moving away from the first end.

[0018] In one exemplary embodiment of this disclosure, the cylinder includes a third section and a fourth section coaxially arranged, the inner diameter of the third section being smaller than the inner diameter of the fourth section, the third section being closer to the first end than the fourth section, a step being formed at the connection between the third section and the fourth section, the outer wall of the guide rod being in contact with the inner wall of the fourth section, and the ball bearing being able to abut against the step to restrict the movement of the guide rod toward the first end.

[0019] In one exemplary embodiment of this disclosure, the mounting device includes a magnetic adsorption element disposed at the first end of the guide rod for magnetically connecting with a magnetic element on the back of the display module.

[0020] In one exemplary embodiment of this disclosure, the magnetic adsorption component includes a mounting base and a magnet; one end of the mounting base is fixedly connected to the first end of the guide rod, and the other end of the mounting base is provided with a first slot and a second slot in sequence along the axial direction of the cylinder. The first slot is closer to the guide rod than the second slot. The magnet is accommodated in the first slot, and the second slot is used to engage the magnetic component on the back of the display module.

[0021] In one exemplary embodiment of this disclosure, the mounting base includes a base body and a connecting portion protruding from one end of the base body. The other end of the base body is provided with a first slot and a second slot. The guide rod is provided with a second guide channel, which is through the rod. The connecting portion extends into the second guide channel and is fixedly connected to it. When the guide rod is in a locked state, the base body abuts against the end of the cylinder.

[0022] This utility model also provides an LED display screen, including a display module, a housing, and the aforementioned mounting device. The mounting device is disposed on the housing, and the display module is mounted on the housing via the mounting device.

[0023] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows:

It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0035] 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 the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] See Figure 1 This application provides an installation device 2 for installing the display module 1 and the housing 3. It can prevent the display module 1 from tilting during installation, making the installation process safe and reliable and preventing damage to the display module 1.

[0037] See also Figures 3 to 5 In some embodiments, the mounting device 2 includes a cylindrical body 21, a guide rod 22, a locking assembly 23, and a magnetic adsorption component. The cylindrical body 21 serves as the outer shell of the mounting device 2, and its hollow interior forms a first guide channel 211. The cylindrical body 21 can be cylindrical or prismatic. The cylindrical body 21 is used to mount and fix it onto the housing 3, thereby fixing the mounting device 2 to the housing 3.

[0038] In some embodiments, the guide rod 22 is rod-shaped and has a certain length. The guide rod 22 passes through the first guide channel 211, which guides the movement of the guide rod 22 so that the guide rod 22 can only move along the axial direction of the first guide channel 211.

[0039] In some embodiments, the guide rod 22 has a first end and a second end opposite to each other. It is understood that the first end and the second end are respectively the two ends in the axial direction of the guide rod 22. The first end of the guide rod 22 faces the display module 1 and is used for detachable connection with the back of the display module 1.

[0040] In some embodiments, the guide rod 22 is movable relative to the cylinder to have switchable locked and unlocked states. In the unlocked state, the guide rod 22 can move along the first guide channel 211 of the cylinder 21, thereby facilitating the translation of the display module 1. In the locked state, the guide rod 22 is fixed to the cylinder 21, thereby connecting the display module 1 and the housing 3 as a single unit after installation.

[0041] In some embodiments, by applying external force to the second end of the guide rod 22, the guide rod 22 can be switched from a locked state to an unlocked state, thereby allowing the display module 1 to be moved away from the housing 3 to remove the display module 1 for maintenance.

[0042] In some embodiments, when it is necessary to install the display module 1 onto the housing 3, the first end of the guide rod 22 is connected to the back of the display module 1. Moving the display module 1 allows it to move along the axis of the first guide channel 211 of the cylinder 21 under the influence of the guide rod 22, enabling the display module 1 to slide into the housing 3 and avoid tilting during installation. When external force is applied to the second end of the guide rod 22, the guide rod 22 is unlocked from the cylinder 21, allowing the display module 1 to move out of the housing 3 along the axis of the first guide channel 211. This facilitates the removal of the display module 1 from the housing 3 without causing it to tilt, thus providing good protection for the display module 1.

[0043] In some embodiments, the guide rod 22 is locked and unlocked by a locking component 23. The locking component 23 includes an elastic element 231 and a ball bearing 232. A mounting hole 223 is provided on the outer peripheral wall of the guide rod 22, and the ball bearing 232 is movably disposed in the mounting hole 223, allowing the ball bearing 232 to move and roll within the mounting hole 223. One end of the elastic element 231 is connected to the guide rod 22, and the other end of the elastic element 231 acts on the ball bearing 232, applying an elastic force to the ball bearing 232 so that the ball bearing 232 can move towards the cylinder 21. Since the guide rod 22 passes through the first guide channel 211, when the ball bearing 232 is pushed outward by the force of the elastic element 231, it is restrained by the inner wall of the first guide channel 211.

[0044] Therefore, the cylinder 21 is provided with a locking position to restrict the movement of the ball 232 along the axial direction of the cylinder 21. When the guide rod 22 is in the locked state, the elastic element 231 abuts against the ball, causing the ball to engage in the locking position, thereby restricting the movement of the ball 232 in the axial direction of the cylinder 21, and restricting the guide rod 22 from continuing to move along the first guide channel 211. It can be understood that the elastic element 231 applies a force to the guide rod 22 to move it toward the inner wall of the first guide channel 211. The locking position is located on the path of the ball 232 moving in the axial direction of the cylinder 21. When the ball 232 just moves to the locking position, it is pushed out by the force of the elastic element 231 and locked in the locking position.

[0045] In some embodiments, when the guide rod 22 is in the unlocked state, the ball 232 and the locking position are disengaged, and the guide rod 22 can move along the first guide channel 211, thereby driving the display module 1 to translate.

[0046] In some embodiments, when the ball 232 is pushed out to the locking position, the ball 232 is at least partially located within the mounting hole 223, thereby contacting the mounting hole 223 and preventing the guide rod 22 from moving further.

[0047] In some embodiments, the locking position can be a groove formed on the inner wall of the first guide channel 211, the shape of which is adapted to the shape of the ball 232. When the ball 232 is driven to the locking position by the guide rod 22, the ball 232 is at least partially pushed out into the groove by the elastic member 231, thereby locking the ball 232 in the groove and preventing it from easily moving along the axial direction of the cylinder 21. Only when the second end of the guide rod 22 is pressed with a large force can the ball 232 be forced to move into the mounting hole 223 and disengage from the groove, thus realizing the switching of the guide rod 22 from the locked state to the unlocked state.

[0048] In some embodiments, the locking position can also be the end edge of the cylinder 21 facing away from the display module 1. When the ball 232 is driven to the locking position by the guide rod 22, the ball 232 is at least partially pushed out by the elastic member 231 to abut against the end edge of the cylinder 21, thereby preventing the ball 232 from moving towards the display module 1. At this time, the guide rod 22 can be locked by setting the first end of the guide rod 22 and the other end of the cylinder 21 to abut against each other, so that the guide rod 22 cannot move in the axial direction of the cylinder 21. When it is necessary to unlock the guide rod 22, the second end of the guide rod 22 is pressed with a large force, so that the ball 232 is forced to move into the mounting hole 223, thereby disengaging the ball 232 from the locking position and releasing the locked state of the guide rod 22. By applying force to the ball 232 through the elastic element 231, the ball 232 can automatically lock into place when the guide rod 22 moves to the locked state without rebound, resulting in higher installation accuracy of the display module 1. When unlocking, the guide rod 22 can be automatically unlocked and moved towards the display module 1 by pressing the second end of the guide rod 22. The operation process is simple and reliable.

[0049] In some embodiments, the cylinder 21 includes a third section 21a and a fourth section 21b arranged coaxially. The inner diameters of the third section 21a and the fourth section 21b are different to form a stepped portion 21c, which abuts against the ball 232 to prevent the guide rod 22 from dislodging from the first guide channel 211 when it moves toward the first end.

[0050] Specifically, the inner diameter of the third segment 21a is smaller than that of the fourth segment 21b. The third segment 21a is closer to the first end of the guide rod 22 than the fourth segment 21b, forming the aforementioned step portion 21c at the connection between the third segment 21a and the fourth segment 21b. The outer wall of the guide rod 22 is in contact with the inner wall of the fourth segment 21b, allowing the guide rod 22 to move precisely along the fourth segment 21b, preventing wobbling during movement. When the guide rod 22 moves towards the first end, the ball bearing 232 is pushed out by the elastic member 231 to contact the inner wall of the first guide channel 211. During the movement of the guide rod 22, the ball bearing 232 can abut against the step portion 21c, thus restricting the movement of the guide rod 22 towards the first end.

[0051] In some embodiments, the mounting hole 223 can be a blind hole, and the elastic element 231 is disposed in the mounting hole 223, so that a force can be applied to the ball 232 to push it outward. When the ball 232 does not move to the corresponding position of the locking position with the guide rod 22, the ball 232 is pushed out by the elastic element 231 until it contacts the inner wall of the first guide channel 211, without affecting the guide rod 22 to continue to move along the first guide channel 211.

[0052] In some embodiments, the guide rod 22 includes a rod body 221 and a locking handle 222 connected to one end of the rod body. The rod body 221 is the main body of the guide rod 22, and it passes through the first guide channel 211. The end of the rod body 221 facing away from the locking handle is the first end of the guide rod 22, which is used to connect with the display module 1. The rod body 221 has a second guide channel 224 along its own axial direction. The second guide channel 224 and the first guide channel 211 are coaxially arranged. A mounting hole 223 is formed on the outer peripheral wall of the rod body 221 and communicates with the second guide channel 224.

[0053] In some embodiments, the locking handle 222 is movably inserted into the second guide channel 224, and the end of the locking handle 222 opposite to the rod body constitutes the second end of the guide rod 22. By pressing the end of the locking handle 222 located outside the second guide channel 224, the rod body 221 can be switched from a locked state to an unlocked state.

[0054] Furthermore, an elastic element 231 is disposed in the second guide channel 224. One end of the elastic element 231 is connected to the inner wall of the second guide channel 224, and the other end of the elastic element 231 acts on the lock handle 222, enabling the rod body 221 to move through the action of the elastic element 231. The lock handle 222 includes a large-diameter section 222a and a small-diameter section 222b coaxially arranged. One end of the small-diameter section 222b extends out of the second guide channel 224, forming the second end of the guide rod 22. The large-diameter section 222a is closer to the first end of the guide rod 22 than the small-diameter section 222b. When the guide rod 22 is in the unlocked state, the outer wall of the small-diameter section 222b abuts against the ball bearing 232; when the guide rod 22 is in the locked state, the outer wall of the large-diameter section 222a abuts against the ball bearing 232.

[0055] By changing the diameter of the large-diameter section 222a and the small-diameter section 222b, as the locking handle 222 moves away from the first end along with the rod 221, the ball 232 gradually changes from contacting the small-diameter section 222b to contacting the large-diameter section 222a. During the switching process, the ball 232 is pressed outward by the large-diameter section 222a, forcing the ball 232 to move toward the inner wall of the first guide channel 211. Thus, when the ball 232 moves with the guide rod 22 to the position opposite to the locking position, the ball 232 is pressed into the locking position and locked.

[0056] It should be noted that one end of the elastic element 231 is connected to the large-diameter section 222a of the rod 221 and is in a compressed state. It applies a force to the large-diameter section 222a to move it away from the first end. When the guide rod 22 is in the unlocked state, the ball 232 is abutted against the connection between the large-diameter section 222a and the small-diameter section 222b. As the rod 221 moves towards the housing 3, when the ball 232 is opposite to the locking position, the restriction of the ball 232 by the inner wall of the first guide cylinder 21 disappears. At this time, the force of the elastic element 231 causes the large-diameter section 222a to continue to move towards the housing 3, so that the outer wall of the large-diameter section 222a abuts against the ball 232, pushing the ball 232 out to the locking position and locking it.

[0057] In some embodiments, the elastic element 231 may be a spring or sheet, which may be configured to be in a compressed state when in the second guide channel 224, thereby continuously applying a force to the large diameter section 222a to move it toward the second end.

[0058] See also Figure 6When it is necessary to unlock the guide rod 22, by pressing the lock handle 222, the large diameter section 222a of the lock handle 222 moves toward the display module 1, thereby compressing the elastic element 231. The elastic element 231 applies a force to the rod body 221, causing it to move toward the display module 1. After the large diameter section 222a moves a certain distance toward the display module 1, it disengages from the ball 232, so that the ball 232 is not pressed against the locking position. The guide rod 22 can move toward the display module 1 under the force of the elastic element 231, thereby causing the ball 232 to disengage from the locking position, resulting in the unlocking of the guide rod 22, which facilitates the outward translation of the display module 1.

[0059] In some embodiments, the lock handle 222 further includes a connecting section 222c, whose two ends are connected to a large-diameter section 222a and a small-diameter section 222b, respectively. The diameter of the connecting section 222c gradually decreases from the large-diameter section 222a to the small-diameter section 222b, thereby making the transition from the large-diameter section 222a to the small-diameter section 222b smoother. When the guide rod 22 switches from the unlocked state to the locked state, the connecting section 222c applies a radial component force of the cylinder 21 to the ball bearing 232, thereby making the ball bearing 232 move more smoothly towards the locked position. The outer wall surface of the connecting section 222c can be an inclined surface or a curved surface.

[0060] In some embodiments, the rod 221 includes a first segment 221a and a second segment 221b coaxially arranged. The second segment 221b is located away from the first end relative to the first segment 221a. The inner diameter of the first segment 221a matches the outer diameter of the larger diameter segment 222a, and the two can form a clearance fit or a transition fit. The inner diameter of the second segment 221b matches the outer diameter of the smaller diameter segment 222b, and the two can form a clearance fit or a transition fit. This arrangement allows the larger diameter segment 222a to move along the inner wall of the first segment 221a, and the smaller diameter segment 222b to move along the inner wall of the second segment 221b, making the lock handle 222 more stable when moving in the second guide channel 224.

[0061] Meanwhile, the second segment 221b protrudes inward relative to the first segment 221a to form a stop portion 221c, and the connecting segment 222c can abut against the stop portion 221c, thereby restricting the lock handle 222 from moving away from the first end and preventing the lock handle 222 from coming out of the second guide channel 224. When installing the lock handle 222, the lock handle 222 can be inserted into the second guide channel 224 from the first end of the guide rod 22.

[0062] In some embodiments, a magnetic adsorption component is disposed at the first end of the guide rod 22, that is, at one end of the rod body 221, and is used to magnetically connect with the magnetic component 11 on the back of the display module 1, thereby facilitating the connection and disassembly of the mounting device 2 and the display module 1. Both the magnetic adsorption component and the magnetic component 11 may include magnets, with opposite sides of the magnets exhibiting opposite magnetic properties, thus attracting each other magnetically.

[0063] In some embodiments, the mounting device 2 and the back of the display module 1 can also be connected by a snap-fit ​​assembly to achieve a detachable connection between the two.

[0064] In some embodiments, the magnetic adsorption component includes a mounting base 24 and a magnet 25. The mounting base 24 is used to mount and fix the magnet 25, and the mounting base 24 itself can be connected to the guide rod 22.

[0065] Specifically, one end of the mounting base 24 is fixedly connected to the first end of the guide rod 22 to securely mount the mounting base 24 onto the guide rod 22. The other end of the mounting base 24 has a first slot 243 and a second slot 244 sequentially formed along the axial direction of the cylinder 21. The first slot 243 is closer to the guide rod 22 than the second slot 244. The magnet 25 in the magnetic adsorption component is housed in the first slot 243 and engaged therein. The second slot 244 is used to engage the magnetic component 11 on the back of the display module 1, so that when the display module 1 is brought close to the mounting device 2, the magnetic component 11 on the back of the display module 1 can be engaged in the second slot 244 for positioning, preventing the display module 1 from dislodging during translation and improving the stability of the connection.

[0066] In some embodiments, the first card slot 243 and the second card slot 244 can be arranged coaxially or staggered. When the first card slot 243 and the second card slot 244 are arranged coaxially, the magnet 25 in the magnetic adsorption component has a stronger adsorption effect with the magnetic component 11 on the back of the display module 1, and the magnetic connection between the two is more stable.

[0067] In some embodiments, the shape of the first slot 243 can be adapted to the shape of the magnet 25 in the magnetic adsorption component to make the magnet 25 more securely engaged. Similarly, the shape of the second slot 244 can be adapted to the shape of the magnetic component 11 on the back of the display module 1 to make the magnetic component 11 more securely engaged.

[0068] In some embodiments, the opening of the first slot 243 is smaller than the opening of the second slot 244, and the two are connected. The magnet 25 in the magnetic adsorption component can be attached to the magnetic component 11, and the two are magnetically attracted more tightly.

[0069] In some embodiments, the mounting base 24 includes a base body 241 and a connecting portion 242 protruding from one end of the base body 241. The other end of the base body 241 has the aforementioned first slot 243 and second slot 244. The base body 241 is the main body of the mounting base 24, and the connecting portion 242 protrudes from the base body 241.
