Description

Technical Field

[0001] The utility model relates to the technical field of controllers, and more specifically, to a self-locking controller cabinet. Background Art

[0002] The controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reversal of the motor. It is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system. The controller is usually installed in a control cabinet to protect it.

[0003] However, the existing controller cabinet needs to open the cabinet door when it is actually used, but the user may forget to close the door or close it loosely after use, thus causing certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a self-locking controller cabinet, which has the advantages of preventing the cabinet door from being forgotten to be closed or not closed tightly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-locking controller cabinet, comprising a control cabinet and a cabinet door, one side of the cabinet door is rotatably connected to the control cabinet, and a locking mechanism is arranged between the other side and the control cabinet; a circular arc guide rail is fixedly connected to the top of the inner wall of the cabinet door, a slider is fixedly connected to the top of the control cabinet, the slider is slidably connected to the circular arc guide rail, and a reset spring is fixedly connected between one end of the circular arc guide rail and the slider; the locking mechanism comprises a mounting plate fixedly arranged on one side of the cabinet door, a mounting shell is fixedly arranged on one side of the control cabinet corresponding to the mounting plate, a locking block is fixedly connected on the plate surface of the mounting plate close to the mounting shell through a connecting rod, a connecting hole is opened on the mounting shell corresponding to the locking block, and wedge-shaped card blocks are symmetrically slidably connected on both sides of the locking block in the mounting shell, a limiting spring is fixedly connected between one end of the wedge-shaped card block away from the locking block and the inner wall of the mounting shell, and the inclined surfaces of the two wedge-shaped card blocks are opposite and face the connecting hole.

[0006] In a preferred embodiment, the locking mechanism further comprises a pull rod fixedly connected to a side of the wedge-shaped block close to the limit spring, the mounting housing is provided with a through hole corresponding to the pull rod, and the pull rod passes through the corresponding through hole.

[0007] In a preferred embodiment, the outer wall of the arc-shaped guide rail is fixedly connected with an arc-shaped rack, a movable groove is opened at the bottom of the sliding block, the top of the movable groove is rotatably connected with a mounting rod, the bottom of the mounting rod is fixedly connected with a transmission gear, and the transmission gear is meshed with the arc-shaped rack.

[0008] In a preferred embodiment, a movable plate is sleeved on the outer wall of the mounting rod, a plurality of limit blocks are fixedly connected to the bottom of the movable plate, and a plurality of limit grooves matching the limit blocks are formed on the top of the transmission gear.

[0009] In a preferred embodiment, the limiting block and the limiting groove are both hemispherical.

[0010] In a preferred embodiment, a plurality of compression springs are fixedly connected between the top of the movable plate and the top of the movable groove.

[0011] The beneficial effects of the utility model are:

[0012] 1. In the utility model, when the cabinet door is opened, the cabinet door drives the slider to move in the circular arc guide rail, thereby driving the reset spring to stretch. After the operation of the controller is completed, the slider is driven to move in the circular arc guide rail by the elastic force of the reset spring, thereby driving the cabinet door to reset. When the cabinet door contacts the control cabinet, the locking block is inserted into the mounting shell through the connecting hole, thereby pushing the two wedge-shaped blocks to move back to each other. Finally, the locking block passes between the two wedge-shaped blocks. Under the elastic force of the limit spring, the wedge-shaped blocks approach each other, thereby limiting the locking block and completing the locking of the cabinet door, effectively avoiding the phenomenon of forgetting to close the cabinet door or not closing it tightly.

[0013] 2. In the utility model, when the cabinet door is automatically closed, the slider moves in the circular arc guide rail, thereby driving the transmission gear to move, and under the action of the circular arc rack, the transmission gear is driven to rotate. At the same time, under the elastic force of the extrusion spring, the movable plate is pushed to move downward continuously, thereby driving the limit block to enter the limit groove. Since the limit block and the limit groove are both hemispherical, the limit block continuously enters and squeezes out of the limit groove during the continuous rotation of the transmission gear, which increases the friction force when the transmission gear rotates, thereby reducing the rotation speed of the transmission gear, effectively preventing the cabinet door from closing too quickly and causing safety hazards.

A limiting spring 19 is bolted between the end of the wedge-shaped block 17 away from the locking block 3 and the inner wall of the mounting shell 22, and the inclined surfaces of the two wedge-shaped blocks 17 are opposite and face the connecting hole 18; the locking mechanism also includes a pull rod 20 connected to the side of the wedge-shaped block 17 close to the limiting spring 19 by bolts, and a through hole 21 is provided in the mounting shell 22 corresponding to the pull rod 20, and the pull rod 20 passes through the corresponding through hole 21. Through the pull rod 20, when the cabinet door 2 is opened, the two pull rods 20 can be pulled outward, thereby driving the two wedge-shaped blocks 17 to move away from each other, thereby releasing the limit on the locking block 3.

[0024] Reference Figure 2-Figure 5 The outer wall of the arc-shaped guide rail 6 is connected with an arc-shaped rack 7 by bolts, and a movable groove 12 is opened at the bottom of the slider 9. The top of the movable groove 12 is rotatably connected with a mounting rod 14. The bottom of the mounting rod 14 is connected with a transmission gear 8 by bolts. The transmission gear 8 is meshed with the arc-shaped rack 7. Through the arc-shaped rack 7, the slider 9 can drive the transmission gear 8 to rotate when it moves in the arc-shaped guide rail 6; the outer wall of the mounting rod 14 is sleeved with a movable plate 13, and the bottom of the movable plate 13 is connected with a plurality of limit blocks 16 by bolts.

[0025] Working principle: when the cabinet door 2 is opened, the sliding block 9 is driven by the cabinet door 2 to move in the arc guide rail 6, thereby driving the reset spring 10 to stretch. After the operation of the controller is completed, the sliding block 9 is driven to move in the arc guide rail 6 by the elastic force of the reset spring 10, thereby driving the cabinet door 2 to reset. When the cabinet door 2 contacts the control cabinet body 1, the locking block 3 is inserted into the mounting shell 22 through the connecting hole 18, thereby pushing the two wedge-shaped blocks 17 to move away from each other. Finally, the locking block 3 passes between the two wedge-shaped blocks 17. Under the elastic force of the limit spring 19, the wedge-shaped blocks 17 approach each other, thereby limiting the locking block 3 and completing the locking of the cabinet door 2, effectively avoiding the phenomenon of forgetting to close the cabinet door 2 or closing it loosely.
