Description

Technical Field

[0001] This utility model belongs to the field of PLC controller technology, and in particular relates to a PLC controller installation device with an anti-collision protection structure. Background Technology

[0002] In industrial automation systems, the PLC controller, as the core control unit, directly impacts production line efficiency and equipment safety through its operational stability. However, existing installation devices suffer from the following core technical problems regarding collision protection:

[0003] PLC controllers are susceptible to sudden mechanical shocks during handling, installation, or equipment operation (such as tools falling and hitting the electrical box, vibrations from the production line being transmitted to the box, or accidental drops during transportation). Traditional installation devices often use rigid metal protective covers or single rubber pad cushioning structures. The former cannot effectively disperse impact forces and is prone to causing dents in the PLC casing or micro-cracks in the internal circuit boards due to localized stress concentration; the latter, due to the limited deformation recovery ability of rubber materials, is prone to fatigue failure in high-frequency vibration environments and cannot continuously provide stable cushioning protection. Utility Model Content

[0004] The purpose of this utility model is to provide a PLC controller installation device with an anti-collision protection structure to solve the technical problems mentioned in the background art, such as dynamic mechanical impact causing deformation of the PLC shell and damage to internal components, and static installation stress concentration causing shell deformation under pressure, which in turn result in the controller having weak impact resistance and high risk of hidden damage.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A PLC controller installation device with an anti-collision protection structure includes a PLC controller and a base plate for supporting and assembling the PLC controller. The feature is that: two protective side plates are symmetrically arranged along the central axis on the front side of the base plate, and a telescopic cover is slidably arranged on the opposite side of the two protective side plates. The protective side plates and the protective side plates cooperate to provide isolation and protection for the PLC controller.

[0006] A connecting plate is inlaid on the surface of the base plate, and a sliding disk is movably installed at one end of the connecting plate opposite to the PLC controller. The PLC controller is movably plugged into the front end of the sliding disk.

[0007] Preferably, a side plate is provided on the front side of the base plate and at the opposite end of the two protective side plates, and the surface of the side plate is provided with a breathable mesh.

[0008] Preferably, a central protective plate is provided in the middle of the front side of the base plate, and a limiting groove is provided on the surface of the central protective plate and on the opposite side of the two protective side plates.

[0009] Preferably, the output end of the telescopic cover is symmetrically connected with limit strips, and the left and right ends of the rear end of the base plate are connected with limit posts that cooperate with the limit strips, and the surface of the limit strips is provided with insertion holes.

[0010] Preferably, an assembly groove is provided in the middle of the surface of the connecting plate, and a sliding column is connected in the middle of the inner cavity of the assembly groove, and an assembly ring groove is provided in the middle of one side of the sliding column.

[0011] Preferably, a counterweight is embedded in the bottom of the sliding disc surface, and the counterweight is used to increase the counterweight at the bottom of the sliding disc surface.

[0012] Preferably, the end of the sliding disc opposite to the PLC controller is connected to a plug plate, and the end of the PLC controller near the sliding disc is integrally connected to a plug rail, and the surface of the plug rail is provided with a plug groove for use with the plug plate.

[0013] Preferably, a frame is provided on the rear side of the base plate, and two plug-in sliding plates are installed vertically and symmetrically along the axis on the rear side of the base plate;

[0014] The top of the frame surface and the surface of the plug-in slide are symmetrically provided with several slots, and a positioning plate is provided through the surface of the plug-in slide.

[0015] The PLC controller mounting device with an anti-collision protection structure of this utility model has the following advantages:

[0016] This is a PLC controller installation device with an anti-collision protection structure. When installing the PLC controller, the base plate is first slidably embedded into the surface of the frame through the two plug-in sliding plates on the rear side. After aligning the frame with the corresponding slots on the plug-in sliding plates, the positioning plate is inserted to achieve quick positioning and fixation of the base plate on the frame.

[0017] This is a PLC controller installation device with an anti-collision protection structure. In this design, the insertion rail at the front of the PLC controller is aligned with the insertion plate on the sliding disc and inserted, so that the insertion groove of the rail engages with the insertion plate, completing the rapid assembly of the PLC controller and the sliding disc. The sliding disc is movably fitted onto the surface of the sliding column on the connecting plate through its assembly ring groove. The "T"-shaped structure of the sliding column and the assembly ring groove limits the displacement range of the sliding disc. At the same time, the counterweight at the bottom of the sliding disc uses gravity to keep it in a vertical state. When an external impact force acts on the base plate, the protective rubber on the contact surface between the connecting plate and the base plate absorbs part of the impact energy, and the remaining impact force is buffered and dispersed by the swing of the sliding disc on the sliding column, thereby reducing the direct impact on the PLC controller. Regarding the protective structure... The two protective side plates on the front of the base plate are fixed to the side plate with bolts. The ventilation mesh on the surface of the side plate, together with the protective side plates, the telescopic cover and the base plate, form a closed protective space. The two ends of the telescopic cover slide into the limiting groove of the protective side plate, and at the same time pass through the through-type limiting groove on the surface of the central protective plate to enhance the structural strength. By pulling the telescopic cover, it is unfolded and covers the front of the PLC controller. At this time, the limiting band at the end of the telescopic cover is inserted into the insertion hole of the limiting post on the rear side of the base plate. The convex plate at the end of the limiting post prevents the limiting band from accidentally falling off, thereby fixing the unfolded state of the telescopic cover. This not only achieves comprehensive anti-collision protection for the PLC controller, but also achieves efficient heat dissipation through the ventilation mesh. Finally, it forms a comprehensive protection system that integrates quick installation, shock absorption, anti-collision protection and heat dissipation functions. Attached Figure Description

[0033] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a PLC controller mounting device with an anti-collision protection structure.

[0034] like Figures 1-8 As shown, the present invention discloses a PLC controller mounting device with an anti-collision protection structure, including a PLC controller 400 and a base plate 100 for supporting and assembling the PLC controller 400. A side plate 110 is provided on the front side of the base plate 100 and at the opposite end of the two protective side plates 300. The adjacent side plates 110 and the opposite side of the adjacent protective side plates 300 are fixedly connected by bolts, and the side plates 110 are fastened to the surface of the base plate 100 by bolts. In this way, with the cooperation of the base plate 100, the side plates 110, the protective side plates 300 and the telescopic cover 330, a closed space can be formed, and the PLC controller 400 can be placed in the space to protect the surface of the PLC controller 400 from collision.

[0035] The surface of the side plate 110 is provided with a breathable mesh. The breathable mesh can dissipate the heat in the space formed by the base plate 100, side plate 110, protective side plate 300 and telescopic cover 330, so that it can not only provide anti-collision protection for the PLC controller 400, but also take into account heat dissipation.

[0036] Two protective side plates 300 are symmetrically arranged along the central axis on the front side of the base plate 100. A telescopic cover 330 is slidably arranged on the opposite side of the two protective side plates 300. The protective side plates 300 and the protective side plates 300 work together to provide isolation and protection for the PLC controller 400. When the PLC controller 400 is mounted on the base plate 100, the protective side plates 300 are located on both sides of the surface of the PLC controller 400, while the telescopic cover 330 can shield the outer surface of the PLC controller 400 to prevent foreign objects from directly colliding with the surface of the PLC controller 400 and causing damage to its surface.

[0037] A central protective plate 310 is provided in the middle of the front side of the base plate 100, and the bottom of the central protective plate 310 is connected to the bottom of the front side of the base plate 100. Limiting grooves 320 are provided on the surface of the central protective plate 310 and on the opposite side of the two protective side plates 300. The limiting grooves 320 provided on the surface of the central protective plate 310 are through-cut. The two ends of the telescopic cover 330 are slidably disposed in the inner cavity of the limiting grooves 320 provided on the surface of the two protective side plates 300. Therefore, the shape of the cavity of the limiting groove 320 is used to guide the telescopic cover 330. When the telescopic cover 330 is extended, it can be moved according to the shape of the cavity of the limiting groove 320 to effectively cover the front side of the PLC controller 400 and protect the front end of the PLC controller 400.

[0038] Specifically, when the central protective plate 310 is provided and the limiting groove 320 is also opened on the surface of the central protective plate 310, the surface of the telescopic cover 330 can pass through the limiting groove 320 opened on the central protective plate 310. The central protective plate 310 is used to assist in guiding the telescopic cover 330 and increase the strength of the telescopic cover 330 itself, so as to prevent the telescopic cover 330 from deforming due to the impact force of the external object when it collides with the telescopic cover 330.

[0039] The output end of the telescopic cover 330 is symmetrically connected to the left and right limit strips 331. The limit strips 331 are made of rubber and have a certain degree of toughness. The left and right ends of the rear end of the base plate 100 are connected to the limit posts 340 that cooperate with the limit strips 331. The surface of the limit strips 331 is provided with insertion holes.

[0040] After the telescopic cover 330 is extended to the top of the base plate 100, the limiting band 331 is pulled and inserted into the limiting post 340 through the insertion hole on the surface to limit the telescopic cover 330 and prevent the telescopic cover 330 from automatically springing back to its original position when there is no external force restraining it.

[0041] Furthermore, a protrusion is connected to one end of the surface of the limiting post 340. After the limiting band 331 is inserted into the limiting post 340, the protrusion can prevent the limiting band 331 from detaching from the limiting post 340 at will.

[0042] A connecting plate 500 is embedded in the surface of the base plate 100, and a sliding disk 520 is movably mounted on the end of the connecting plate 500 opposite to the PLC controller 400. The PLC controller 400 is movably inserted and mounted on the front end of the sliding disk 520. By setting the PLC controller 400 and the sliding disk 520 to be movably assembled, the base plate 100 can be prevented from being impacted, and when the impact force is transmitted to the sliding disk 520, the impact force brought by the sliding disk 520 to the PLC controller 400 can be buffered and reduced, thereby effectively protecting the PLC controller 400.

[0043] The surface where the connecting plate 500 contacts the base plate 100 is covered with protective rubber, which can reduce the impact force transmitted from the base plate 100 to the connecting plate 500.

[0044] Specifically, the PLC controller 400 and the sliding disc 520 are movably assembled using the following structure: an assembly groove 501 is provided in the middle of the surface of the connecting plate 500, and a sliding column 510 is connected to the middle of the inner cavity of the assembly groove 501. An assembly ring groove 521 is provided in the middle of one side of the sliding column 510, and the sliding disc 520 is movably fitted onto the surface of the sliding column 510 through the assembly ring groove 521 provided on its surface.

[0045] The surface shape of the sliding joint 510 and the cavity shape of the assembly ring groove 521 are both "T" shaped.

[0046] A counterweight 522 is embedded in the bottom of the surface of the sliding disc 520. The counterweight 522 is used to increase the counterweight at the bottom of the surface of the sliding disc 520, so that after the sliding disc 520 is movably fitted onto the surface of the sliding post 510, the bottom of the sliding disc 520 fitted with the counterweight 522 is always at the bottom. Even if the sliding disc 520 shifts on the surface of the sliding post 510, the bottom of the sliding disc 520 can always be kept at the bottom under the action of the counterweight 522.

[0047] The sliding disc 520 is connected to a plug plate 530 at one end opposite to the PLC controller 400, and the PLC controller 400 is integrally connected to a plug rail 540 at one end near the sliding disc 520. The surface of the plug rail 540 is provided with a plug slot 541 for use with the plug plate 530.

[0048] The insertion plate 530 is L-shaped. When installing the PLC controller 400 on the sliding disc 520, simply align the insertion slot 541 of the insertion rail 540 with the insertion plate 530 to quickly insert the PLC controller 400 into the sliding disc 520. Therefore, the PLC controller 400 can be installed quickly with fewer bolts used, while also providing anti-collision protection for the PLC controller 400.

[0049] To quickly install the PLC controller 400 in the electrical box, refer to Figure 2 and Figure 8 As shown, a frame 200 is provided on the rear side of the base plate 100, and the frame 200 is fastened to the electrical box by bolts. Two plug-in slide plates 210 are vertically and symmetrically installed on the rear side of the base plate 100 along the axis. When the base plate 100 is installed on the frame 200, the two symmetrically arranged plug-in slide plates 210 slide against the upper and lower ends of the frame 200 on opposite sides, so that the base plate 100 can be directly inserted into the surface of the frame 200 through the plug-in slide plates 210.

[0050] To position the base plate 100 and prevent it from moving freely on the frame 200, several slots 211 are symmetrically provided on the top surface of the frame 200 and the surface of the insertion slide plate 210. A positioning plate 220 is provided through the surface of the insertion slide plate 210. The surface of the positioning plate 220 is inserted into the adjacent slots 211 on the frame 200 and the insertion slide plate 210. This prevents the base plate 100 from moving freely left and right or forward and backward on the frame 200, thereby assisting in the installation of the base plate 100 and the PLC controller 400. This replaces the traditional bolt fastening installation and increases the flexibility of the PLC controller 400 installation.

[0051] The working principle of a PLC controller installation device with an anti-collision protection structure is as follows: When installing the PLC controller 400, the base plate 100 is first slidably embedded into the surface of the frame 200 via the two rear plug-in slide plates 210. After aligning the frame 200 with the corresponding slots 211 on the plug-in slide plates 210, the positioning plate 220 is inserted to achieve quick positioning and fixation of the base plate 100 on the frame 200. Subsequently, the insertion rail 540 at the front end of the PLC controller 400 is aligned with the insertion plate 530 on the sliding disc 520 and inserted, so that the insertion slot 541 of the insertion rail 540 and the insertion plate 530 are aligned. The PLC controller 400 and the sliding disc 520 are quickly assembled with zero engagement. The sliding disc 520 is movably fitted onto the surface of the sliding post 510 on the connecting plate 500 via its assembly ring groove 521. The "T"-shaped structure of the sliding post 510 and the assembly ring groove 521 limits the displacement range of the sliding disc 520. At the same time, the counterweight 522 at the bottom of the sliding disc 520 uses gravity to keep it in a vertical state. When an external impact force acts on the base plate 100, the protective rubber on the contact surface between the connecting plate 500 and the base plate 100 absorbs part of the impact energy, and the remaining impact... The force is buffered and dispersed by the swinging of the sliding disc 520 on the sliding column 510, thereby reducing the direct impact on the PLC controller 400. Regarding the protective structure, the two protective side plates 300 on the front side of the base plate 100 are fixedly connected to the side plate 110 by bolts. The ventilation mesh on the surface of the side plate 110, together with the protective side plates 300, the telescopic cover 330, and the base plate 100, forms a closed protective space. The telescopic cover 330 slides into the limiting grooves 320 of the protective side plates 300 at both ends, and simultaneously passes through the through-type limiting groove 320 on the surface of the central protective plate 310 to increase... With strong structural strength, the telescopic cover 330 is pulled to unfold and cover the front of the PLC controller 400. At this time, the limiting band 331 at the end of the telescopic cover 330 is inserted into the insertion hole of the limiting post 340 on the rear side of the base plate 100. The convex plate at the end of the limiting post 340 prevents the limiting band 331 from accidentally falling off, thereby fixing the unfolded state of the telescopic cover 330. This not only achieves comprehensive anti-collision protection for the PLC controller 400, but also achieves efficient heat dissipation through the breathable mesh. Finally, it forms a comprehensive protection system that integrates quick installation, shock absorption, anti-collision protection and heat dissipation functions.

[0052] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
