AI Technical Summary
In existing PLC electrical engineering automation rotary supports, if the gear tooth grooves are not accurately aligned, the support angle may shift due to external forces or vibrations, affecting the stability of the equipment.
The locking mechanism includes a fixed shaft, collar, gripper, arm and spring. The friction force is increased by the contact between the gripper and the friction surface of the support column. Combined with the design of the pedal and the squeezing block, the support column can be reliably locked.
This improves the stability of the support frame, prevents angular displacement caused by external forces or vibrations, and ensures the stability and reliability of equipment operation.

[0002] Electrical engineering automation is a professional discipline, and PLC refers to a programmable logic controller, which is an indispensable part of electrical engineering automation. Generally, algorithms and steps are programmed on the PLC in electrical engineering automation. After the programming is completed, the PLC can control mechanical equipment to automatically complete operations according to programmed instructions. The PLC is generally provided with a display screen and a key. When supporting and operating the PLC device, such as the display screen, a corresponding support is usually used for support.

A recess is arranged on the bottom plate and is connected with the outside. A foot stepping component for limiting the support column is arranged in the recess. The foot stepping component comprises a limiting plate rotatably connected with the left and right groove walls of the recess through a rotating shaft. A torsion spring is arranged on the rotating shaft. A clamping block is fixedly installed on the bottom surface of the limiting plate and is clamped and matched with the gap between the two adjacent teeth of the gear. An installation assembly is arranged on the protruding column. The rotating support can be adjusted and operated, is simple in operation, low in cost and convenient to use.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] This embodiment provides a rotating bracket for PLC electrical engineering automation, such as... Figures 1-5 As shown, the rotating bracket includes a base plate 1 and a support column 2 rotatably mounted on the base plate 1. Several support rods 5 are evenly distributed on the base plate 1. The upper end of the support rod 5 is equipped with a fixing seat 4 for mounting the support column 2. The upper end of the support column 2 is provided with a slide rail 3. The base plate 1 is provided with a locking mechanism 6.
[0024] The locking mechanism 6 includes a fixed shaft 64 symmetrically arranged on the base plate 1 and a collar 65 sleeved on the fixed shaft 64. The collar 65 is fixedly installed with a gripper 651 on the side closer to the support column 2, and an arm 652 is fixedly installed on the side of the collar 65 away from the support column 2. A spring 69 is provided between the two arms 652.
[0025] Specifically, the fixed shaft 64 is symmetrically arranged on one side of the support column 2, the two clamping jaws 651 are oppositely arranged on the fixed shaft 64, the particle surface 66 at the front end of the two clamping jaws 651 is in contact with the support column 2, and after the support column 2 is rotated to a specified position, the two clamping jaws 651 can be kept clamped on the support column 2. When it is necessary to rotate the support column 2, only two arm rods 652 need to be installed, so that the clamping jaw 651 is no longer in contact with the support column 2, and the clamping jaw 651 can be released from the clamping state.
[0026] The support column 2 is provided with a friction surface 7, and one end of the clamping jaw 651 is provided with a particle surface 66 in contact with the support column 2.
[0027] More specifically, the friction surface 7 arranged on the support column 2 corresponds to the particle surface 66 on the clamping jaw 651, thereby increasing the friction when the two are in contact, improving the stability during clamping, and avoiding the slight rotation of the staff when adjusting the PLC control installed on the bracket.
[0028] The bottom plate 1 is provided with a hinge seat 63, the hinge seat 63 is provided with a shaft rod 68, the hinge seat 63 is provided with a pedal 61, the pedal 61 is sleeved with the connecting seat 62, and one end of the connecting seat 62 close to the support column 2 is provided with an extrusion block 672 connected with the arm rod 652.
[0029] Further,
[0030] The hinge seat 63 supports the pedal 61, and the connecting seat 62 at the lower end of the pedal 61 is sleeved with the shaft rod 68, so that the staff can step on the pedal 61. After the staff steps on the pedal 61, the extrusion block 672 is driven to move downward, so that the two arm rods 652 are close to each other, and the clamping jaw 651 clamping the support column 2 is released.
[0031] The lower end of the pedal 61 is provided with a sliding groove 612, and the sliding groove 612 is fixedly provided with a limiting rod 613. The limiting rod 613 is sleeved with a connecting block 611, and the connecting block 611 is hingedly provided with a positioning seat 673 connected with the extrusion block 672.
[0032] Further, the sliding groove 612 at the lower end of the pedal 61 is sleeved with the connecting block 611 and the limiting rod 613, so that the pedal 61 can be horizontally and longitudinally moved through the connecting block 611.
[0033] The bottom plate 1 is provided with a guide rail frame 67, the guide rail frame 67 is slidably connected with a limiting block 671, and the limiting block 671 is fixedly connected with the extrusion block 672.
[0034] It should be noted that the guide rail frame 67 is connected with the extrusion block 672 through the limiting block 671, and the extrusion block 672 can avoid deviation when moving up and down by limiting the guide rail frame 67.
[0035] The arm rod 652 is provided with a supporting groove 653 matched with the extrusion block 672.
[0036] It is worth mentioning that the supporting groove 653 provided on the arm rod 652 is mainly used for extruding the two arm rods 652 to move close to each other when the extrusion block 672 moves downward.
[0037] In use, the bottom plate 1 serves as a base, and the support column 2 is rotatably connected with the base through a bearing or a rotating shaft. A plurality of support rods 5 are equidistantly fixed on the bottom plate 1 and annularly limit the support column 2 through the top fixing seat 4. The slide rail 3 at the top of the support column 2 can be installed with a PLC device to realize multi-angle rotation adjustment. The locking mechanism 6 is composed of symmetrical fixing shafts 64, a sleeve ring 65, clamping jaws 651, arm rods 652 and springs 69. When the two arm rods 652 are pressed, the sleeve ring 65 rotates around the fixing shaft 64, drives the clamping jaws 651 to separate from the support column 2, and after the arm rods 652 are released, the springs 69 automatically rebound to make the clamping jaws 651 tightly grip the support column 2.
[0038] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
