[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] See also Figures 1 to 3 , a connection lock buckle 100 provided by an embodiment of the present invention includes a connection seat 110, a movable rod 120, a locking member 130 and an elastic member 140, wherein the connection seat 110 is provided with a plug-in portion 112, and the plug-in portion 112 is provided with a guide channel 1121 along its axial direction, the axial direction of the plug-in portion 112 is the plug-in direction of the plug-in portion 112, and the side of the plug-in portion 112 is provided with a guide hole 1122 connected to the guide channel 1121; the movable rod 120 is slidably arranged in the sliding guide channel 1121, and the side of the movable rod 120 is provided with a makeshift groove 121 for matching with the guide hole 1122; the locking member 130 is movably arranged on the side of the plug-in portion 112 along the guide hole 1122. The elastic member 140 is used to provide an elastic restoring force for the movable rod 120 so that the clearance groove 121 and the guide hole 1122 are offset; wherein, when the clearance groove 121 and the guide hole 1122 coincide with each other, the locking member 130 can move toward the clearance groove 121 to be located inside the side portion of the plug-in portion 112; when the clearance groove 121 and the guide hole 1122 are offset, the outer peripheral wall of the movable rod 120 abuts against the locking member 130 so that the locking member 130 is at least partially exposed to the outer wall of the connecting seat 110.

[0041] There are one or more locking members 130. If there are multiple locking members 130, correspondingly, multiple guide holes 1122 are provided around the connection base 110, and the locking members 130 are arranged one by one in the guide holes 1122. In addition, the connection base 110 and the bottom shell 220 of the display module 200 can be assembled and connected, such as being connected by screws. The connection base 110 and the bottom shell 220 of the display module 200 can also be integrated and connected, such as being integrally formed, or being welded.

[0042] When applied to a display device, the connection base 110 is connected to the bottom shell 220 of the display module 200. Under the action of the elastic member 140, the movable rod 120 has the clearance groove 121 and the guide hole 1122 staggered, that is, the outer peripheral wall of the movable rod 120 and the side of the locking member 130 close to the guide channel 1121 are in contact with each other. Therefore, under the restriction of the movable rod 120, the locking member 130 is partially exposed to the outer wall of the connection base 110. The exposed part of the locking member 130 is engaged with the box frame 300 (refer to Figure 4 and Fig. 9 ), so that the display module 200 is assembled on the box frame 300.

[0043] Among them, if it is necessary to remove the display module 200 from the box frame 300, the user controls the movable rod 120 to slide along the guide channel 1121, the clearance groove 121 on the side wall of the movable rod 120 coincides with the guide hole 1122, and the locking piece 130 can move toward the clearance groove 121. As a result, the movable rod 120 releases the restriction on the locking piece 130, and the locking piece 130 can move toward the clearance groove 121. The locking piece 130 is hidden in the connecting seat 110, thereby releasing the axial restriction between the connecting seat 110 and the box frame 300, and the connecting seat 110 and the box frame 300 can be separated, so that the display module 200 can be easily removed from the box frame 300. If it is necessary to reinstall the display module 200 on the box frame 300, the user controls the movable rod 120 to slide along the guide channel 1121, and the clearance groove 121 on the side wall of the movable rod 120 coincides with the guide hole 1122, and the locking member 130 can move toward the clearance groove 121 to be hidden in the connecting seat 110. Of course, if the movable rod 120 is continued to slide, the locking member 130 is squeezed to be exposed to the outer wall of the connecting seat 110 and is engaged with the box frame 300. Therefore, when the display module 200 is assembled on the box frame 300, since the locking member 130 can be hidden in the connecting seat 110, there is no interference between the locking member 130 and the box frame 300, and the connecting seat 110 can be conveniently connected to the box frame 300, so that the display module 200 can be conveniently assembled on the box frame 300.

[0044] In some embodiments, reference Figures 3 to 5The locking member 130 is configured as a ball, that is, the surface of the locking member 130 is configured as an arc surface, and the surface of the locking member 130 has a guiding function. Therefore, when the connecting seat 110 is connected to the box frame 300, the side of the locking member 130 facing the movable rod 120 can smoothly roll along the guide hole 1122 toward the outside of the connecting seat 110 under the action of the movable rod 120, so as to conveniently engage with the box frame 300, thereby facilitating the assembly of the display module 200; when the connecting seat 110 is disassembled from the box frame 300, the side of the locking member 130 facing away from the movable rod 120 can smoothly slide along the guide hole 1122 toward the inner side of the connecting seat 110 under the action of the box frame 300, thereby conveniently realizing the disassembly of the connecting seat 110 and the box frame 300, thereby facilitating the disassembly of the display module 200. In other possible embodiments, the locking member 130 may also be configured as a rod-shaped body, and the two ends of the locking member 130 may be configured with rounded corners, which can also conveniently push the locking member 130 to slide inward or outward along the guide hole 1122 to facilitate the installation and disassembly of the display module 200.

[0045] In some embodiments, reference Figures 3 to 5 , the give-way groove 121 is arranged in an annular shape around the movable rod 120. When used, the give-way groove 121 is arranged in an annular shape. When the movable rod 120 slides along the guide channel 1121, there is no need to locate the circumferential position of the connecting seat 110 and the movable rod 120, and each locking member 130 can be embedded in the give-way groove 121. It can be understood that no additional circumferential restriction structure is required between the connecting seat 110 and the movable rod 120 to ensure that the guide hole 1122 and the give-way groove 121 are on the same axial straight line, thereby, the connection structure between the movable rod 120 and the connecting seat 110 is simple and the assembly is convenient. In other possible embodiments, a plurality of give-way grooves 121 can be provided, and each give-way groove 121 is provided in a one-to-one correspondence with the guide hole 1122.

[0046] In some embodiments, reference Figures 3 to 5 Along the axial direction of the movable rod 120, the yielding groove 121 has a first groove wall 122 and a second groove wall 123 opposite to each other, and the first groove wall 122 and the second groove wall 123 are arranged to expand outwardly in an inclined manner, that is, the first groove wall 122 and the second groove wall 123 are inclined surfaces arranged outwardly in an inclined manner, and the first groove wall 122 is closer to the display module 200 than the second groove wall 123 (refer to Figure 1). It can be understood that the first groove wall 122 is set as an outwardly expanding inclined surface. When the movable rod 120 slides along the guide channel 1121, the movable rod 120 can use the first groove wall 122 to smoothly act on the locking member 130 outward, thereby pushing the locking member 130 to move outward along the guide hole 1122, thereby, the movable rod 120 can smoothly slide along the guide channel 1121, and make the locking member 130 and the box frame 300 snap-fit; at the same time, when the movable rod 120 needs to be pulled out, the movable rod 120 can use the second groove wall 123 to smoothly act on the locking member 130 outward, thereby pushing the locking member 130 to move outward along the guide hole 1122, thereby, the movable rod 120 can be smoothly pulled out from the guide channel 1121, thereby facilitating the disassembly of the connection lock 100.

[0047] In some embodiments, reference Figures 3 to 5 The plug-in portion 112 is provided with an insertion end 1124, which is used to be inserted into the connecting hole 311 on the box frame 300 so that the locking member 130 can be snapped into the box frame 300, and the elastic force of the elastic member 140 acts on the movable rod 120 in the insertion direction of the insertion end 1124 of the plug-in portion 112.

[0048] In a specific application, the movable rod 120 slides toward the insertion end 1124 of the plug-in portion 112 under the action of the elastic member 140, and the locking member 130 is separated from the clearance groove 121 of the movable rod 120. At this time, under the action of the side wall of the movable rod 120, the locking member 130 is partially exposed outside the plug-in portion 112 to be engaged with the box frame 300 (refer to Figure 4 When the display module 200 needs to be disassembled, the action of the elastic member 140 is overcome, and the movable rod 120 slides in a direction away from the box frame 300, so that the positioning groove 121 moves to the position of the locking member 130 (refer to Figure 5 ), therefore, the locking member 130 can move toward the clearance groove 121, and then the axial restriction between the locking member 130 and the box frame 300 can be released. With this arrangement, the movable rod 120 is easier to operate, thereby facilitating the disassembly of the display module 200, which will be described in detail later.

[0049] Instead of the elastic member 140 acting on the movable rod 120 in the direction of the insertion end 1124 of the plug-in portion 112, in other possible embodiments, the elastic member 140 acts on the movable rod 120 in the direction of the insertion end 1124 away from the plug-in portion 112. As a result, the movable rod 120 slides toward the display module 200 under the action of the elastic member 140, and the locking member 130 disengages from the clearance groove 121 of the movable rod 120. Similarly, under the action of the side wall of the movable rod 120, the locking member 130 is partially exposed outside the plug-in portion 112 to be engaged with the box frame 300.

[0050] In some embodiments, reference Figures 3 to 5 The insertion end 1124 of the plug-in portion 112 is provided with a protrusion port 1123, and the end of the movable rod 120 protrudes through the protrusion port 1123. It can be understood that when the axial restriction between the locking member 130 and the box frame 300 needs to be released, the user overcomes the force of the elastic member 140, so that the movable rod 120 slides toward the display module 200, and the clearance groove 121 of the movable rod 120 slides to the position of the locking member 130, and the locking member 130 can move toward the clearance groove 121, thereby releasing the axial restriction between the connecting seat 110 and the box frame 300, and then the display module 200 can be easily disassembled.

[0051] In some embodiments, reference Figures 3 to 5 The connection base 110 is further provided with a connection bottom 111 connected to the plug-in portion 112, and the connection bottom 111 is used for assembly connection or integrated connection with the bottom shell 220 of the display module 200 (refer to Figure 6 and Figure 7 ). An installation cavity 1111 is provided on the inner side of the connecting bottom 111, and one end of the guide channel 1121 away from the extension port 1123 is connected to the installation cavity 1111, and the movable rod 120 partially extends into the installation cavity 1111. A clearance opening 1112 is provided on the bottom of the connecting bottom 111 away from the plug-in portion 112, and more specifically, the clearance opening 1112 is provided on the side of the connecting bottom 111 close to the bottom shell 220 of the display module 200. The elastic member 140 can be a spring and is provided in the installation cavity 1111, one end of the elastic member 140 is against the bottom shell 220 of the display module 200, and the other end is against the end of the movable rod 120 close to the display module 200, thereby, the elastic member 140 acts on the movable rod 120 in the direction of the plug-in portion 112, and in this way, the movable rod 120 and the elastic member 140 can be conveniently installed on the inner side of the connecting seat 110 through the installation cavity 1111.

[0052] In some embodiments, referring to FIG. Figure 6 and Figure 7The movable rod 120 is made of a magnetic material, such as a metal material, such as iron, stainless steel, etc. The movable rod 120 can be driven by the magnetic attraction from the direction of the clearance opening 1112 to move toward the clearance opening 1112. Specifically, the clearance opening 1112 is arranged facing the display module 200, and the external magnetic attraction member is placed on the front of the display module 200 and is located at a position corresponding to the clearance opening 1112. Then, the magnetic attraction member generates a magnetic attraction force toward the display module 200 to the movable rod 120 through the clearance opening 1112, and the movable rod 120 overcomes the force of the elastic member 140 and moves toward the display module 200. The clearance groove 121 of the movable rod 120 moves to the position of the locking member 130, and the locking member 130 can move toward the clearance groove 121, thereby releasing the axial restriction between the connecting seat 110 and the box frame 300, thereby facilitating the disassembly of the display module 200.

[0053] In some embodiments, reference Figure 4 and Figure 8 , the movable rod 120 can be driven by the negative pressure from the clearance opening 1112 to move toward the clearance opening 1112. Specifically, the clearance opening 1112 is arranged facing the display module 200, and the suction cup of the external negative pressure source 400 is placed on the front of the display module 200 and located at the position corresponding to the clearance opening 1112; at the same time, the display module 200 is also provided with a suction hole 210, and the suction hole 210 is located between the suction cup of the negative pressure source 400 and the clearance opening 1112. Then, the negative pressure source 400 draws away the air in the installation cavity 1111 through the suction hole 210. At this time, the movable rod 120 overcomes the force of the elastic member 140 under the action of atmospheric pressure and moves toward the display module 200. The clearance groove 121 of the movable rod 120 moves to the position of the locking member 130. The locking member 130 can move toward the clearance groove 121, thereby releasing the axial restriction between the connecting seat 110 and the box frame 300, thereby facilitating the disassembly of the display module 200.

[0054] Furthermore, the connection lock buckle 100 further includes a movable glue 150 disposed in the installation cavity 1111, and the movable rod 120 is connected to the movable glue 150. In this configuration, a section of the movable rod 120 close to the clearance opening 1112 is in a sealed space. The negative pressure source 400 can fully extract the gas in the installation cavity 1111 through the suction hole 210, so that the installation cavity 1111 is in a relatively large negative pressure state. The movable glue 150 can be deformed toward the clearance opening 1112 under the action of atmospheric pressure, and the movable rod 120 can move toward the clearance opening 1112, so that the clearance groove 121 of the movable rod 120 can move to the position of the locking member 130, thereby releasing the axial restriction between the connection seat 110 and the box frame 300.

[0055] It can be understood that, through the setting of the movable glue 150, while ensuring the sealing setting of the movable rod 120 and the connecting seat 110, the movable glue 150 also has a sufficiently large deformation to meet the movement of the movable rod 120 under the negative pressure state. Therefore, the yield groove 121 of the movable rod 120 can move to the position of the locking piece 130.

[0056] Furthermore, in order to make the movable glue 150 have a sufficiently large deformation, the movable glue 150 is provided with a corrugated portion 1511 located around the movable rod 120. With such a configuration, when the movable rod 120 moves toward the clearance opening 1112 under the action of atmospheric pressure, the corrugated portion 1511 of the movable glue 150 is stretched, thereby satisfying the movement of the movable rod 120. When the movable rod 120 is restored toward the guide channel 1121 under the action of the elastic member 140, the corrugated portion 1511 is restored to a contracted state. It can be understood that when the movable rod 120 moves toward the clearance opening 1112, the corrugated portion 1511 of the movable glue 150 can be deformed to adapt to the movement of the movable rod 120, so that the movable rod 120 can smoothly move toward the clearance opening 1112, and the solution can be smoothly implemented.

[0057] In a specific embodiment, referring to Figure 4 , Figure 6 and Figure 7 The movable rubber 150 is a negative pressure cover body arranged inside the installation cavity 1111. The negative pressure cover body is provided with a negative pressure port 1521 located at the clearance opening 1112. The movable rod 120 is partially located inside the negative pressure cover body. Specifically, the negative pressure cover body includes a cover body portion 151 and a peripheral portion 152. The peripheral portion 152 is connected to the four sides of the cover body portion 151. The cover body portion 151 is roughly located at the bottom of the installation cavity 1111 close to the guide channel 1121. The movable rod 120 is connected to the center of the cover body portion 151. The corrugated portion 1511 is arranged on the cover body portion 151. The outer peripheral surface of the peripheral portion 152 is fitted on the inner wall of the installation cavity 1111, and a negative pressure port 1521 is formed at the position of the clearance opening 1112. A section of the movable rod 120 is located inside the negative pressure cover body. It can be seen that the movable rod 120 is sealed with the installation cavity 1111 through the negative pressure cover body. When the connecting lock 100 is assembled on the display module 200, the edge of the surrounding edge portion 152 away from the cover portion 151 is sealed and connected to the bottom shell 220 of the display module 200, and the suction hole 210 (refer to Figure 8 ) is connected to the inner side of the negative pressure cover body through the negative pressure port 1521.

[0058] In specific applications, the negative pressure source 400 can fully extract the gas in the negative pressure cover through the suction hole 210. Under the action of atmospheric pressure, the cover body 151 is deformed toward the display module 200 through the corrugated part 1511, and the movable rod 120 moves toward the display module 200. The clearance groove 121 of the movable rod 120 moves to the position of the locking member 130, and the locking member 130 can move toward the clearance groove 121, thereby releasing the axial restriction between the connecting seat 110 and the box frame 300.

[0059] In other possible embodiments, the movable glue 150 is directly and sealably connected to the inner arm of the installation cavity 1111 around the movable glue 150 , and the movable glue 150 does not extend to the position of the opening 1112 , and the movable rod 120 is sealed with the installation cavity 1111 through the movable glue 150 .

[0060] The present application also discloses a display device, referring to, Figure 4 and Fig. 9 , including a box frame 300, a display module 200 and the above-mentioned connection lock 100, a connection seat 110 and a bottom shell 220 of the display module 200 are assembled and connected, such as the two are assembled and connected by screws, or the connection seat 110 and the bottom shell 220 of the display module 200 are integrally connected, such as the two are integrally formed, or the two are welded. At the same time, a connection part 310 is provided on the box frame 300, and the connection part 310 is provided with a connection hole 311, the connection seat 110 is penetrated through the connection hole 311, and the locking member 130 is clamped on the side of the connection part 310 away from the display module 200.

[0061] It can be understood that the display device adopts the above-mentioned connecting lock 100. If it is necessary to remove the display module 200 from the box frame 300, the user controls the movable rod 120 to slide along the guide channel 1121, and the yield groove 121 on the side wall of the movable rod 120 coincides with the guide hole 1122. The locking piece 130 can move toward the yield groove 121. As a result, the movable rod 120 releases the restriction on the locking piece 130, and the locking piece 130 can move toward the yield groove 121. The locking piece 130 is hidden in the connecting seat 110, thereby releasing the axial restriction between the connecting seat 110 and the box frame 300, and the connecting seat 110 and the box frame 300 can be separated, so that the display module 200 can be easily removed from the box frame 300. If it is necessary to reinstall the display module 200 on the box frame 300, the user controls the movable rod 120 to slide along the guide channel 1121, the clearance groove 121 on the side wall of the movable rod 120 coincides with the guide hole 1122, and the locking member 130 can move toward the clearance groove 121 to be hidden in the connecting seat 110. Therefore, when the display module 200 is assembled on the box frame 300, since the locking member 130 can be hidden in the connecting seat 110, there is no interference between the locking member 130 and the box frame 300, and the connecting seat 110 can be conveniently connected to the box frame 300, so that the display module 200 can be conveniently assembled on the box frame 300.
