Abstract
Description
Technical Field
[0001] This utility model relates to the field of controller housing technology, and in particular to a controller housing opening and closing limiting mechanism. Background Technology
[0002] The controller housing opening and closing features innovative designs such as elastic buckles, limit plate linkage, and breathable protection, which improve disassembly and assembly efficiency, reliability, and environmental adaptability. Future technologies will develop towards intelligence, modularity, and high-performance materials.
[0003] The existing controller consists of a housing and a cover, which rotate using two sets of unique damped hinges to open and close the cover. However, during use, due to the highly integrated internal circuitry, which is often distributed across multiple PCBs with blind and buried vias connecting the layers, locating faults requires specialized equipment (such as X-rays or CT scans), making it quite troublesome. Furthermore, the limited space inside the housing makes it difficult for staff to troubleshoot internal circuitry, causing significant inconvenience and wasting considerable repair time.
[0004] To address this issue, we propose a controller housing opening and closing limit mechanism. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a controller housing opening and closing limit mechanism.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: the upper end of the controller housing is connected to the controller cover via a hinge rod, and connecting rods are fixedly installed on both sides inside the controller housing. A first buffer spring is sleeved on the middle surface of the connecting rod, and sliding blocks are connected to both ends of the first buffer spring. A first hinge is fixedly installed on the upper end of the sliding block. The interior of the first hinge is hinged to one end of a support rod, and the other end of the support rod is hinged to the interior of a second hinge. The second hinge is fixedly installed below the platform plate.
[0007] Preferably, a platform plate is provided at the middle position inside the controller chassis, and the front and rear sides of the platform plate are set in an arc shape.
[0008] Preferably, support cylinders are fixedly installed on both sides of the inner surface of the controller cover, and the bottom of the support cylinders is set in an arc shape.
[0009] Preferably, the sliding block has a through hole that matches the connecting rod, and the diameter of the screw hole in the sliding block is smaller than the diameter of the first buffer spring.
[0010] Preferably, one end of the sliding block is connected to a fixed pull rod, and the outer side of the fixed pull rod is fixedly installed on the surface of the fixed box.
[0011] Preferably, a fixing block is installed inside the fixing box. The fixing block is welded to one end of the second buffer spring, and the other end of the second buffer spring is welded to the mounting block. Half of the mounting block is set in a semi-circular arc shape.
[0012] Preferably, the mounting block is connected to the rotating rod via a bearing, the two ends of the rotating rod are connected to a fixed disc, and the fixed disc is fixedly connected to the inner wall of the limiting rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This device features connecting rods fixedly installed on both sides inside the controller housing, with a first buffer spring installed at the center of each connecting rod. Sliding blocks are fixedly installed at both ends of the first buffer spring, facilitating movement of the sliding blocks by pulling them with the first buffer spring. Simultaneously, a first hinge is fixedly installed on the upper end of each sliding block, hinged to one end of a support rod inside the first hinge, and the other end of the support rod is hinged to the inside of a second hinge. This facilitates the lifting and lowering of the platform plate, enabling effective maintenance of the internal circuitry of the controller housing. This prevents difficulties in maintenance due to limited internal space and complex circuitry, avoiding excessive time wastage and improving maintenance efficiency.
[0015] 2. This device has a sliding block at one end connected to a fixed pull rod, and the outer side of the fixed pull rod is fixedly installed on the surface of the fixed box. A limit rod is installed on the outer side of the fixed box to effectively limit the platform plate. This facilitates effective protection of the internal circuitry under different conditions, preventing damage to internal parts by workers during the lifting and lowering of the platform plate. At the same time, a fixed block is installed inside the fixed box, and one end of the second buffer spring is welded to the fixed block, and the other end is welded to the mounting block. Fixed discs are installed on both sides of the inner wall of the limit rod and connected to the rotating rod. The mounting block is connected to the rotating rod through bearings, which facilitates limit protection in special situations. Under normal conditions, the device limits and retracts to prevent affecting the lifting and lowering of the platform plate and avoid affecting the efficiency of maintenance work.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A controller housing opening and closing limiting mechanism includes: a controller housing 1, with a controller cover 11 connected to the upper end of the controller housing 1 via a hinge rod, facilitating the opening and closing of the housing and protecting the interior; connecting rods 2 are fixedly installed on both sides inside the controller housing 1, facilitating the movement of sliding blocks 22; a first buffer spring 21 is sleeved on the middle surface of the connecting rod 2, with sliding blocks 22 connected to both ends of the first buffer spring 21, facilitating the movement of the sliding blocks 22 to lift and lower a platform plate 13; a first hinge 23 is fixedly installed on the upper end of the sliding block 22, facilitating the pressing and lifting of a support rod 24; the interior of the first hinge 23 is hinged to one end of the support rod 24, facilitating the rotation of the support rod 24 during lifting and lowering to prevent jamming and affecting the lifting and lowering of the platform plate 13; the other end of the support rod 24 is hinged to the interior of a second hinge 25, which is fixedly installed below the platform plate 13 to support the platform plate 13 and improve the lifting and lowering efficiency of the platform plate 13.
[0023] Furthermore, refer to Figure 1 and Figure 2 It can be seen that a platform plate 13 is provided in the middle of the controller housing 1 to effectively support the internal circuit boards and circuit boards. The front and rear sides of the platform plate 13 are rounded to prevent the inner wall of the housing from scraping during the lifting process, which would affect the lifting speed and prevent jamming. Supporting cylinders 12 are fixedly installed on both sides of the inner surface of the controller cover 11 to facilitate the compression of the platform plate 13 and prevent the circuit boards and circuit boards from accidentally colliding with the controller cover 11. The bottom of the supporting cylinders 12 is rounded to facilitate the compression of the platform plate 13 during the closing process and prevent jamming.
[0024] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the sliding block 22 has a through hole that matches the connecting rod 2, so that the sliding block 22 can slide on the surface of the connecting rod 2 and prevent jamming and loosening. The diameter of the screw hole in the sliding block 22 is smaller than the diameter of the first buffer spring 21. This is to prevent the first buffer spring 21 from penetrating the sliding block 22 during the movement of the sliding block 22, so as to avoid affecting the lifting function.
[0025] Furthermore, refer to Figure 3 and Figure 4 It can be seen that one end of the sliding block 22 is connected to a fixed pull rod 31, which makes it easy to pull the sliding block 22 to move. The outer side of the fixed pull rod 31 is fixedly installed on the surface of the fixed box 3 for effective connection, which facilitates internal limiting and prevents the platform plate 13 from rising in special circumstances.
[0026] Furthermore, refer to Figure 4 It can be seen that a fixing block 32 is installed inside the fixing box 3. The fixing block 32 is welded to one end of the second buffer spring 33, which facilitates the welding and fixing of the second buffer spring 33 and prevents it from breaking during the limiting process, thus affecting the limiting effect. The other end of the second buffer spring 33 is welded to the mounting block 34, and half of the mounting block 34 is set in a semi-circular arc shape, which facilitates the movement and extension of the limiting rod 35, preventing jamming and affecting the lifting and lowering of the platform plate 13.
[0027] Furthermore, refer to Figure 4 It can be seen that the mounting block 34 is connected to the rotating rod 37 through the bearing, which facilitates the rotation of the mounting block 34. The two ends of the rotating rod 37 are connected to the fixed disk 36 to improve the rotation efficiency. The fixed disk 36 is fixedly connected to the inner wall of the limiting rod 35.
[0028] Working Principle: In use, the hinge rod rotates to open the controller cover 11 at the top of the controller housing 1, causing it to move upwards. This lifts the support cylinder 12 away from the surface of the platform plate 13. Simultaneously, it pulls the limiting rod 35, causing the mounting block 34, welded to one end of the second buffer spring 33, to stretch the limiting rod 35 away from the side of the controller housing 1. The rotating rod 37 rotates to make the limiting rod 35 laterally positioned and inserted into the fixing box 3. At this point, the first buffer spring 21 installed on the surface of the connecting rod 2 pulls the sliding blocks 22 on both sides closer together. The first hinge 23 pushes the support rod 24, causing the second hinge 25 to rise, thus raising the platform plate 13. Furthermore, pulling the controller cover 11 closes... When the support cylinder 12 is in contact with the surface of the platform plate 13, the first buffer spring 21 pushes the sliding block 22 to move in opposite directions at both ends. The support rod 24 pulls the second hinge 25 down, causing the platform plate 13 to follow. At this time, the fixed pull rod 31 installed at one end of the sliding block 22 pushes the fixed box 3 to extend out of the hole provided on the side of the controller housing 1. At the same time, the limiting rod 35 located inside the fixed box 3 is pulled out, which drives the second buffer spring 33 to stretch. The fixed discs 36 installed on both sides of the inner wall of the limiting rod 35 are sleeved on both ends of the rotating rod 37, which drives the rotating rod 37 to rotate, so that the limiting rod 35 is in a vertical shape. The tension of the second buffer spring 33 makes the limiting rod 35 abut against the outside of the controller housing 1.
[0029] The above is the complete working principle of this utility model.
