Description

Technical Field

[0001] The utility model relates to the technical field of large-screen display, in particular to an installation locking structure and a display screen. Background Art

[0002] Large-screen displays are now widely used in indoor and outdoor spaces of large shopping malls, commercial streets and other scenes due to their high brightness, long life and wide viewing angle.

[0003] At the same time, in order to meet people's increasing demand for visual stimulation, the size of display screens is getting larger and larger. In order to cope with the larger and larger display modules, the corresponding fixing mechanism of the display module usually adopts a fixing mode that cannot be quickly disassembled. Although it meets the requirements of installation stability of the display module, its defects are also obvious. The inability to quickly assemble and disassemble means that the installation and maintenance of the display module are very inconvenient. In the event of display abnormalities, the problem cannot be quickly eliminated and solved. Therefore, an installation and fixing structure is needed that can withstand the installation and fixation of large-size display screens while also facilitating quick installation and disassembly.

[0005] In order to solve the above technical problems, the utility model provides an installation locking structure for detachably fixing an installation body and a fixed body, comprising:

[0006] A lock shell, the lock shell is fixed on the fixed body, and a limiting groove is provided on the lock shell;

[0007] An actuating member, which is disposed in the lock housing and can reciprocate in a direction perpendicular to the fixed body;

[0008] A locking assembly, the locking assembly comprising a guide member, a connecting rod with one end hinged to the guide member, a locking tongue arranged on the guide member, the other end of the connecting rod being hinged to the actuating member, the guide member being slidably arranged on the limiting groove and being able to slide along the limiting groove driven by the connecting rod;

[0009] The mounting body is placed close to the fixed body, and the actuating member is pulled toward the mounting body to move. The guide member is driven to move in the limiting groove by the connecting rod. When the connecting rod rotates around the hinge with the actuating member to a position horizontal to the fixed body, the connecting rod is perpendicular to the actuating member, and the guide member moves to the end of the limiting groove. At the same time, the guide member drives the locking tongue to move parallel to the mounting body, and presses the mounting body against the fixed body, and the mounting body and the fixed body are locked with each other. Then, the actuating member is pushed in the reverse direction to move away from the mounting body, driving the connecting rod to move. The connecting rod drives the locking tongue to withdraw in the reverse direction through the guide member, and the locking structure is unlocked.

[0010] As a more preferred manner, a step structure is provided on the contact surface between the locking tongue and the mounting body, and the mounting body is pressed against the fixed body by utilizing steps of different heights on the step structure to meet the locking requirements of mounting bodies and fixed bodies of different thicknesses.

[0011] As a more preferred embodiment, the limit groove is an arc-shaped long groove, and the end of the arc-shaped long groove is located at the vertex of the arc-shaped long groove. In this way, when the guide member moves to the end of the limit groove, the guide member drives the lock tongue to move toward the installation body, thereby making the installation body and the fixed body locked more firmly.

[0012] As a more preferred manner, a sliding groove is provided on the guide member, and the locking tongue is slidably disposed on the guide member through the sliding groove.

[0013] As a more preferred manner, a plurality of fastening holes are provided on the lock housing, a plurality of threaded holes are opened at corresponding positions of the fixed body, and the lock housing and the fixed body are fixed by screws passing through the fastening holes and the threaded holes.

[0014] As a more preferred manner, the installation locking structure further comprises a pull rod, wherein the pull rod is connected to the actuating member, and the actuating member is driven to reciprocate in a direction perpendicular to the fixed body by pulling the pull rod.

[0015] As a more preferred manner, the actuating member is made of magnetic material, and magnets are used to attract the actuating member on the installation body side and the fixed body side respectively, so that the actuating member can reciprocate in a direction perpendicular to the fixed body.

[0016] As a more preferred manner, the actuating member is made of magnetic material, and by utilizing the principle that like charges repel and opposite charges attract, magnets are respectively used to attract or repel the actuating member on the installation body side and the fixed body side, thereby achieving reciprocating motion of the actuating member in a direction perpendicular to the fixed body.

[0017] As a more preferred embodiment, the installation locking structure also includes an elastic member, both ends of which are respectively connected to the fixed body and the actuating member, and the elastic member applies an elastic force to the actuating member away from the fixed body. The elastic force applied to the actuating member by the elastic member is used to push the actuating member toward the installation body, and then the locking tongue is driven by the guide member to move parallel to the installation body, thereby locking the installation body.

[0018] In order to solve the above problems, the utility model also provides a display screen, including:

[0019] One or more display modules and a mounting chassis for mounting the display modules;

[0020] One or more of the installation locking structures are used to detachably mount the display module on the installation chassis.

[0021] As described above, the installation locking structure and display screen of the utility model have the following beneficial effects: when the installation locking structure of the utility model is used to detachably set the installation body on the fixed body, the installation body is brought close to the fixed body, the action piece is pulled toward the installation body, and the guide piece is driven to move in the limit groove through the connecting rod, and when the connecting rod rotates around the hinge with the action piece to a position horizontal to the fixed body, the connecting rod is perpendicular to the action piece, and the guide piece moves to the end of the limit groove. At the same time, the guide piece drives the lock tongue to move parallel to the installation body and presses the installation body against the fixed body, and the installation body and the fixed body are locked with each other; then the action piece is pushed in the opposite direction to move in the direction away from the installation body, driving the connecting rod to move, and the connecting rod drives the lock tongue to withdraw in the opposite direction through the guide piece, and the locking structure Unlock; when the connecting rod rotates around the hinge with the actuating piece to a position horizontal to the fixed body, the connecting rod is perpendicular to the actuating piece, and the guide piece moves to the end of the limit slot. At this time, the guide piece can only move in the opposite direction of the limit slot under the action of the limit slot. When the guide piece is acted upon by an external force and moves in the opposite direction along the limit slot, the force applied to the connecting rod is applied to the actuating piece along the connecting rod. Because the connecting rod is perpendicular to the actuating piece at this time, the forces applied by the connecting rod to the actuating piece are all perpendicular to the actuating piece, and the actuating piece can only move in a direction perpendicular to the fixed body. Therefore, when the connecting rod is perpendicular to the actuating piece, the forces applied by the connecting rod to the actuating piece cannot make the actuating piece move along its axial direction. Therefore, the installation locking structure is in a stable state at this time, and the installation body can be effectively detachably set on the fixed body.

[0022] The display screen of the utility model uses the above-mentioned installation locking structure to detachably set the display module on the installation chassis, which can stably fix the display module on the installation chassis and conveniently realize the installation and removal of the display module through the installation locking structure.

[0023] To sum up, the installation locking structure and display screen of the utility model realize effective fixation of the installation body while ensuring the requirements of quick assembly and disassembly through the locking structure design with stable structure and easy operation, which solves the problem that the installation structure and display screen in the prior art cannot simultaneously ensure the stable fixation requirements and quick assembly and disassembly requirements of large-size display screens.

[0064] An actuating member 12, wherein the actuating member 12 is disposed in the lock housing 11 and can reciprocate in a direction perpendicular to the fixed body 2;

[0065] The locking assembly 13 includes a guide member 131, a connecting rod 132 with one end hinged to the guide member 131, and a locking tongue 133 arranged on the guide member 131. The other end of the connecting rod 132 is hinged to the actuating member 12. The guide member 131 is slidably arranged on the limiting groove 113 and can slide along the limiting groove 113 driven by the connecting rod 132.

[0066] The installation body 3 is placed close to the fixed body 2, and the action piece 12 is pulled to move toward the installation body 3. The guide piece 131 is driven to move in the limit groove 113 through the connecting rod 132. When the connecting rod 132 rotates around the hinge with the action piece 12 to a position horizontal to the fixed body 2, the connecting rod 132 is perpendicular to the action piece 12, and the guide piece 131 moves to the end of the limit groove 113. At the same time, the guide piece 131 drives the locking tongue 133 to move parallel to the installation body 3, and presses the installation body 3 onto the fixed body 2, and the installation body 3 and the fixed body 2 are locked with each other; then, the action piece 12 is pushed in the reverse direction to move away from the installation body 3, driving the connecting rod 132 to move, and the connecting rod 132 drives the locking tongue 133 to withdraw in the reverse direction through the guide piece 131, and the locking structure is unlocked.

[0067] In order to better introduce the installation locking structure 1 of the utility model, it is now explained in combination with the following specific application: when the installation locking structure 1 of the utility model is used to detachably set the installation body 3 on the fixed body 2, the installation body 3 is brought close to the fixed body 2, the action piece 12 is pulled toward the installation body 3, and the guide piece 131 is driven to move in the limiting groove 113 by the connecting rod 132, and when the connecting rod 132 rotates around the hinge with the action piece 12 to a position horizontal to the fixed body 2, the connecting rod 132 is perpendicular to the action piece 12, and the guide piece 131 moves to the end of the limiting groove 113.

At this time, the guide member 131 can only move in the opposite direction along the limiting groove 113 under the action of the limiting groove 113. When the guide member 131 is acted upon by an external force and moves in the opposite direction along the limiting groove 113, the force applied to the connecting rod 132 is applied to the action piece 12 along the connecting rod 132. At this time, the connecting rod 132 is perpendicular to the action piece 12, and the guide member 131 moves to the end of the limiting groove 113. The connecting rod 132 is perpendicular to the actuating member 12, and the force applied by the connecting rod 132 to the actuating member 12 is perpendicular to the actuating member 12, and the actuating member 12 can only move in a direction perpendicular to the fixed body 2. Therefore, when the connecting rod 132 is perpendicular to the actuating member 12, the force applied by the connecting rod 132 to the actuating member 12 cannot make the actuating member 12 move along its axial direction.

[0083] As described above, the installation locking structure and display screen of the present invention have the following beneficial effects: when the installation locking structure 1 of the present invention is used to detachably set the installation body 3 on the fixed body 2, the installation body 3 is brought close to the fixed body 2, the action piece 12 is pulled toward the installation body 3, and the guide piece 131 is driven to move in the limit groove 113 by the connecting rod 132, and when the connecting rod 132 rotates around the hinge with the action piece 12 to a position horizontal with the fixed body 2, the connecting rod 132 and the action piece 12 are connected. The action piece 12 is vertical, the guide piece 131 moves to the end of the limiting groove 113, and at the same time, the guide piece 131 drives the locking tongue 133 to move parallel to the installation body 3, and presses the installation body 3 onto the fixed body 2, and the installation body 3 and the fixed body 2 are locked with each other; then, the action piece 12 is pushed in the reverse direction to move away from the installation body 3, driving the connecting rod 132 to move, and the connecting rod 132 drives the locking tongue 133 to withdraw in the reverse direction through the guide piece 131, and the locking structure is unlocked; When the connecting rod 132 rotates around the hinge with the action piece 12 to a position horizontal to the fixed body 2, the connecting rod 132 is perpendicular to the action piece 12, and the guide piece 131 moves to the end of the limiting groove 113. At this time, the guide piece 131 can only move in the opposite direction along the limiting groove 113 under the action of the limiting groove 113. When the guide piece 131 is acted upon by an external force and moves in the opposite direction along the limiting groove 113, the force applied to the connecting rod 132 is applied to the action piece 12 along the connecting rod 132. At this time, the connecting rod 132 is perpendicular to the action piece 12, and the guide piece 131 moves to the end of the limiting groove 113. 132 is perpendicular to the actuating member 12, and the force applied by the connecting rod 132 to the actuating member 12 is perpendicular to the actuating member 12, and the actuating member 12 can only move in a direction perpendicular to the fixed body 2. Therefore, when the connecting rod 132 is perpendicular to the actuating member 12, the force applied by the connecting rod 132 to the actuating member 12 cannot make the actuating member 12 move along its axial direction. Therefore, at this time, the installation locking structure 1 is in a stable state, and the installation body 3 can be effectively detachably set on the fixed body 2.
