DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the quick connection locking device 100 of the embodiment of the present application includes a shell 110, a latch 120 and an unlocking member 130, the shell 110 includes a first side wall 111 and a second side wall 112, the first side wall 111 includes a first opening 1111, and the second side wall 112 includes a second opening (not shown in the figure); the latch 120 includes a connecting portion 121 and a latch portion 122, the latch portion 122 includes a first section 1221, a second section 1222 and a third section 1223 connected in sequence, one end of the first section 1221 is connected to the connecting portion 121, and the second section 1222 is bent to a side away from the connecting portion 121, the first section 1221 and the third section 1223 are located inside the shell 110, and the second section 1222 extends out of the shell 110 from the first opening 1111; the unlocking member 130 is connected to the connecting portion 121, and is used to drive the first section 1221 and the third section 1223 to approach each other under the pressure of an external force. When two quick-connect locking devices 100 are disposed adjacent to each other, the second section 1222 of the latch 120 of one housing 110 is snap-connected with the second opening of another adjacent housing 110 to achieve detachable connection of the two adjacent housings 110 .

[0029] In the quick connection locking device 100 of the embodiment of the present application, the housing 110 includes a first side wall 111 and a second side wall 112. When two adjacent quick connection locking devices 100 need to be assembled and connected, the two housings 110 are arranged adjacent to each other, the first side wall 111 of one housing 110 is arranged adjacent to the second side wall 112 of the other housing 110, and the buckle portion 122 extends from the first opening 1111 and is buckled and connected to the second opening of the second side wall 112 of the other housing 110, so that the two housings 110 can be detachably connected. The first section 1221 and the third section 1223 are connected to the second section 1222 on both sides of the second direction Z. When the two adjacent quick connection locking devices 100 need to be detached, the unlocking member 130 is used to drive the second section 1222 to narrow along the second direction Z, and the second section 1222 can be detached from the second opening of the other housing 110, so that the two housings 110 are separated. The quick connection locking device 100 has a simple structure, is easy to operate, and can be assembled and disassembled reliably and efficiently. Applying it to the assembly of PLC modules can realize the rapid assembly and disassembly of PLC modules.

[0030] In some embodiments of the present application, the position and size of the first opening 1111 are the same as those of the second opening to simplify the structure of the shell 110; in other embodiments, the positions of the first opening 1111 and the second opening are set correspondingly, and the opening size can be flexibly adjusted according to the buckle design.

[0031] like Figure 1 and Figure 2As shown, in some embodiments of the present application, the shell 110 also includes a third side wall 113 connecting the first side wall 111 and the second side wall 112 , the third side wall 113 includes a pressing port 1131 , and the unlocking member 130 includes a pressing portion 132 , which extends out of the pressing port 1131 .

[0032] The first side wall 111 and the second side wall 112 are arranged opposite to each other along the first direction X. The third side wall 113 connects the first side wall 111 and the second side wall 112 on one side of the second direction Z. The pressing portion 132 protrudes from a side of the unlocking member 130 close to the third side wall 113 and extends out of the shell 110 from the pressing opening 1131.

[0033] By applying an external force to the pressing portion 132 , the first section 1221 can be pushed to move toward the third section 1223 , so that the second section 1222 is narrowed and the second section 1222 can be separated from the second opening.

[0034] In other embodiments, the connecting portion 121 may be driven to move in other ways. For example, a portion of the unlocking member 130 may extend out of the housing 110 from other side walls to facilitate application of external force.

[0035] like Figure 1 As shown, further, two third side walls 113 are provided, and the two third side walls 113 are arranged in parallel. The latch 120 and the unlocking member 130 are configured as a connecting assembly 140. The quick connection locking device 100 includes two connecting assemblies 140, each connecting assembly 140 is arranged near the corresponding third side wall 113, and the unlocking member 130 of each connecting assembly 140 extends out of the pressing port 1131 of the corresponding third side wall 113.

[0036] Specifically, the first side wall 111 and the second side wall 112 are arranged opposite to each other along the first direction X, the two third side walls 113 are arranged in parallel along the second direction Z, and the two connecting components 140 are arranged opposite to each other along the second direction Z, and the connecting components 140 correspond to the third side walls 113 one by one.

[0037] Through this arrangement, the number of snap connections between two adjacent shells 110 can be increased, thereby firmly connecting the two adjacent shells 110.

[0038] In other embodiments, the number of the connecting components 140 may be one, three, four, etc.

[0039] like Figure 5 and Figure 6 As shown, in some embodiments of the present application, the connecting portion 121 is snap-connected with the unlocking member 130 .

[0040] With this arrangement, the latch 120 and the housing 110 can be assembled first, the unlocking member 130 and the housing 110 can be assembled, and then the two can be connected by snapping from the inside of the housing 110, thereby simplifying the assembly process of the latch 120 and the unlocking member 130.

[0041] In other embodiments, the connecting portion 121 and the unlocking member 130 may also be assembled and connected in other ways.

[0042] like Figure 5 As shown, further, the connecting portion 121 is provided with two switch connecting holes 1211 , and the unlocking member 130 is provided with two snap hooks 131 , and the switch connecting holes 1211 and the snap hooks 131 are snap-connected in a one-to-one correspondence.

[0043] The two switch connection holes 1211 are arranged at intervals along the third direction Y, and the positions of the snap hooks 131 correspond one-to-one with the switch connection holes 1211. Correspondingly, two snap members 120 are also provided, and the two snap members 120 are arranged at intervals along the third direction Y, and the positions and numbers of the snap members 120, the first openings 1111 and the second openings correspond one-to-one.

[0044] With this arrangement, by applying external force to the pressing portion 132 , the snap hook 131 can be inserted into the switch connecting hole 1211 , thereby achieving assembly of the connecting portion 121 and the unlocking member 130 .

[0045] In other embodiments, a snap hook may be provided on the connecting portion 121 , and a switch connecting hole may be provided on the unlocking member 130 .

[0046] In some embodiments of the present application, the middle portion of the second section 1222 has a transition portion with a smooth curved transition, thereby reducing the stress concentration therein and reducing the risk of the second section 1222 breaking after multiple elastic deformations.

[0047] In other embodiments, the middle portion of the second segment 1222 may also be bent in a sharp angle.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, a portion of the second section 1222 close to the first section 1221 is provided with a locking protrusion 1225 .

[0049] When the two shells 110 are arranged adjacent to each other along the first direction X, the locking protrusion 1225 is arranged on the outer surface of the second section 1222, and the second section 1222 is inserted into the second opening of the other shell 110. The locking protrusion 1225 abuts against the inner side of the second side wall 112 of the shell 110 from the inside to prevent the second section 1222 from detaching from the second opening.

[0050] In other embodiments, a locking protrusion 1225 may also be provided at a portion of the second section 1222 close to the third section 1223 , and the two locking protrusions 1225 prevent the second section 1222 from being separated from the second opening from both sides.

[0051] In some embodiments of the present application, the buckle portion 122 further includes a fourth section 1224 extending from an end of the third section 1223 away from the second section 1222 , and the fourth section 1224 is used to abut against the inner side of the first side wall 111 .

[0052] The fourth section 1224 abuts against the first side wall 111 from the inside of the housing 110 to prevent the buckle portion 122 from escaping from the housing 110 along the first direction X.

[0053] As a preferred implementation form, the fourth section 1224 is a barb structure at the tail of the entire snap portion 122, which abuts against the side of the first opening 1111 along the second direction Z away from the first section 1221, and the pressing portion 132 of the unlocking member 130 and the third side wall 113 can slide together along the second direction Z, and cooperate with the fourth section 1224 to fix the relative position of the snap portion 120 inside the shell 110.

[0054] In other embodiments, the fourth section 1224 may also extend along the third direction Y and abut against the inner wall around the first opening 1111 .

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present application, one of the first side wall 111 and the second side wall 112 includes a positioning column 1122, and the other includes a positioning hole 1112, and the positioning column 1122 is inserted into the positioning hole 1112 to guide the first side wall 111 of one shell 110 and the second side wall 112 of another adjacent shell 110 to fit together.

[0056] As an example form, the outer side of the second side wall 112 protrudes to form a positioning column 1122, and the corresponding position of the first side wall 111 is provided with a positioning hole 1112; as another example form, the first side wall 111 is provided with a positioning column, and the second side wall 112 is provided with a positioning hole.

[0057] The positioning column 1122 cooperates with the positioning hole 1112 to guide the first side wall 111 and the second side wall 112 of the two adjacent housings 110 to cooperate accurately, and can play a foolproof role and improve assembly efficiency. In particular, when the snap connection between the snap member 120 and the second opening fails, the positioning column 1122 and the positioning hole 1112 can still play a traditional plug-in cooperation mode to ensure the position accuracy of the two housings 110.

[0058] The positioning column 1122 and the corresponding positioning hole 1112 are configured to form a guide assembly. In some embodiments of the present application, the number of fasteners 120 corresponds one-to-one to the number of guide assemblies, and a guide assembly is arranged near each fastener 120. In other embodiments, the position and number of guide assemblies can also be flexibly adjusted according to actual conditions.

[0059] In some embodiments of the present application, along the thickness direction of the housing 110 , the first side wall 111 and the second side wall 112 are arranged in parallel.

[0060] That is, along the first direction X, the first side wall 111 and the second side wall 112 are arranged in parallel.

[0061] Through this arrangement, two adjacent shells 110 can be detachably connected along the first direction X, thereby reducing the overall outer dimensions after assembly.

[0062] In other embodiments, the first side wall 111 and the second side wall 112 may also be arranged to be inclined.

[0063] like Figure 7 As shown, the PLC connection module 200 of some embodiments of the present application includes at least two quick-connect locking devices 100, and the second section 1222 of the latch 120 of one quick-connect locking device 100 is latched and connected with the second opening of another adjacent quick-connect locking device 100 to achieve detachable connection between the two adjacent quick-connect locking devices 100.

[0064] The interior of the housing 110 is used to install the PLC module. Through the above-mentioned assembly method, multiple PLC modules can be assembled or disassembled simply and reliably.

[0065] It is understandable that the functions and specifications of two adjacent PLC modules may be different, and the internal structures and dimensions of two adjacent shells 110 may be correspondingly different, but this does not affect the structural design related to the assembly of the shell 110 mentioned in the embodiment of the present application.

[0066] The working principle of the quick connection locking device 100 of the embodiment of the present application is as follows:

[0067] When two quick-connect locking devices 100 are assembled, the second section 1222 of the buckle 120 of one quick-connect locking device 100 is inserted into the second opening of the other quick-connect locking device 100 along the first direction X, and is squeezed and deformed by the second opening with its own arc as the force transmission direction. After the second section 1222 enters the other shell 110, the locking protrusion 1225 abuts against the second side wall 112 of the shell 110 from the inside of the shell 110, and the fourth section 1224 abuts against the first side wall 111 of the previous shell 110 from the inside, so as to realize the buckle connection of the two shells 110;

[0068] When the two quick-connect locking devices 100 need to be disassembled, the pressing portion 132 is pressed, and the first section 1221 is deformed downward by the force, thereby driving the locking protrusion 1225 to move downward, and the mutual interference between the second section 1222 and the second opening is eliminated, and then the two shells 110 can be separated.

[0069] The use of the quick connection locking device 100 of the embodiment of the present application can realize the rapid disassembly and assembly of two adjacent PLC modules, which not only improves the assembly efficiency of the PLC module but also has a good connection strength.

[0070] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0071] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
