Description

Technical Field

[0001] The utility model relates to the technical field of PLC controllers, in particular to a quick disassembly and assembly type PLC controller component. Background Art

[0002] Programmable Logic Controller (PLC) is a digital computing and operating electronic system designed specifically for use in industrial environments. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input and output. PLC controllers are used and installed in control boxes. PLC controllers are usually installed in control boxes through base plates and bolts. However, under certain working conditions, the internal space of the control box is small or there are too many electronic components installed, which makes the installation of PLC controllers more complicated. At the same time, due to the small space or compact structure, it is difficult to remove the PLC controller when the PLC controller needs to be repaired. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a quick-disassembly and assembly-type PLC controller component to solve the problems of cumbersome installation of traditional PLC controllers and inconvenient installation in a small space.

[0004] To achieve the above-mentioned purpose, the utility model provides a quick-disassembly and assembly PLC controller component, including a base plate and a PLC controller for installation on external tooling, the PLC controller including a shell, a socket is arranged at the center of the base plate, the shell is rotatably arranged on the base plate and a plug shaft for plugging with the socket is opened on the shell, matching plates are arranged at both ends of the shell, baffles are relatively arranged on the base plate, two baffles are arranged on both sides of the socket, a rib is bent on the baffle, the rib is arranged opposite to the base plate and a swinging groove for inserting the matching plate after the shell rotates is formed therebetween, the radial cross-section of the swinging groove is arc-shaped and the arc direction is consistent with the swinging direction of the matching plate, a positioning member for positioning the matching plate when the matching plate is plugged into the swinging groove and a fixing member for fixing the shell in conjunction with the positioning member are arranged on the rib.

[0005] The benefits of adopting the above technical solution are: the operator installs the base plate in the external tooling, and then moves the PLC controller to the base plate. At this time, the operator rotates the shell so that the matching plates at both ends of the shell are respectively located on the upper and lower sides of the base plate. Then the operator rotates the shell so that the shell drives the matching plate to swing, and the matching plate swings and is inserted into the swing groove, thereby realizing the front and rear limit of the shell relative to the thickness direction of the base plate. Then the operator positions the matching plate through the positioning piece and fixes the shell through the linkage between the fixing piece and the positioning piece, thereby realizing the fixation of the shell relative to the base plate. The entire disassembly and assembly process is fast and efficient, and it is also suitable for a control box with a compact structure. It only needs to install the base plate before installing the PLC and rotate the shell to realize the matching of the base plate and the shell, so as to realize the positioning of the shell. The matching of the jack and the plug shaft in the above technology realizes the limitation of the shell relative to the length direction of the base plate, thereby improving the limiting strength of the shell and the stability of the shell on the base plate. At the same time, the setting of the above technology improves the disassembly and assembly efficiency of the shell.

[0006] The utility model is further configured as follows: a plurality of positioning grooves are provided on the inner wall of the retaining edge along its arc direction, a positioning bead is movably arranged in each of the positioning grooves, a reset spring is connected between the positioning bead and the bottom wall of the positioning groove, a plurality of limiting grooves are provided on the matching plate, the two matching plates correspond one-to-one to the two retaining edges and the plurality of limiting grooves on the matching plate correspond one-to-one to the plurality of positioning beads on the corresponding retaining edges, and the positioning beads are positioning members.

[0007] The benefits of adopting the above technical solution are: when the mating plate swings and is inserted into the swing groove, the outer wall of the mating plate pushes open a number of positioning beads in turn, allowing the positioning beads to slide in the positioning groove; when the mating plate is fully inserted into the swing groove, the positioning beads are driven by the reset spring to slide and reset and engage with the corresponding limit groove, thereby achieving the positioning of the mating plate in the swing groove, and then achieving the positioning of the shell, thereby improving the stability of the shell on the base plate, and at the same time facilitating the operator to disassemble and assemble the PLC controller.

[0008] The utility model is further provided with: two openings are penetrated through the retaining edge, the two openings are symmetrically arranged, each of the openings is connected with a pin shaft, and the pin shaft is the fixing member.

[0009] The benefits of adopting the above technical solution are: after the matching plate and the locating bead are positioned, the operator can insert the pin so that the pin is plug-fitted into the opening, and at the same time, the outer peripheral wall of the pin partially abuts against the outer wall of the shell, and the clamping and limiting of the shell is achieved through two symmetrically arranged pins, that is, the positioning of the shell is achieved through four pins, thereby improving the stability of the shell on the base plate, and making it convenient for the operator to disassemble and assemble the PLC controller.

[0010] The utility model is further configured as follows: two convex edges are relatively arranged on the outer peripheral wall of the plug shaft, the plug hole is provided with notches corresponding to the two convex edges, and a card groove for engaging with the two convex edges is circumferentially opened on the inner peripheral wall of the plug hole, and the two notches are connected to the card groove.

[0011] The benefits of adopting the above technical solution are: when the plug shaft gradually approaches the socket, the two convex edges are respectively plugged into and matched with the notches at the corresponding positions until the convex edge is inserted into the socket; when the plug shaft and the socket are fully plugged into and matched and the operator rotates the shell, the convex edge swings accordingly and is inserted into the slot; the convex edge is limited by the slot, making it difficult for the shell to separate from the bottom plate along the thickness direction of the bottom plate, thereby improving the connection strength between the shell and the bottom plate.

[0012] The utility model is further provided with: a wear-resistant pad is attached to the outer peripheral wall surface of the matching plate, and the wear-resistant pad is made of wear-resistant rubber material.

[0013] The advantages of adopting the above technical solution are as follows: the provision of the wear-resistant pad in the above technology improves the friction strength between the matching plate and the inner wall of the baffle, thereby improving the stability of the matching plate in the swing groove.

[0014] The utility model is further provided with: a plurality of mounting bolts for matching with the threads of the pre-buried holes on the external tooling are arranged on the bottom plate.

[0015] The benefit of adopting the above technical solution is that the installation bolts in the above technology are used to connect the base plate with external tooling. BRIEF DESCRIPTION OF THE DRAWINGS
