Description

Technical Field

[0001] This utility model relates to the field of industrial cabinet door lock technology, specifically a single-point industrial cabinet door lock with a padlock hole. Background Technology

[0002] An industrial enclosure door lock is a locking device used for industrial enclosures (specifically, industrial ovens). Its core function is to reliably lock the enclosure door (such as an oven door) through the cooperation of the locking element and the limiting groove, preventing accidental opening of the door and ensuring the stability of the internal environment and operational safety of the industrial enclosure. In the field of industrial production, the door lock device of industrial enclosures (such as industrial ovens, control cabinets, material storage boxes, etc.) is a key component to ensure the safe operation of equipment, prevent unauthorized operation, and maintain the stability of the internal environment.

[0003] An existing technology, such as the oven door lock structure disclosed in CN221143913U, includes an oven body with a heating cavity, a door installed on the oven body for closing and opening the heating cavity, and a door lock device for keeping the door tightly closed when closed. The door lock device includes a limiting plate, a transmission assembly, and a drive assembly. The limiting plate is installed at the opening of the heating cavity. The transmission assembly is connected to the limiting plate. The drive assembly is connected to the transmission assembly. When the door is closed in the heating cavity, the drive assembly drives the limiting plate to move via the transmission assembly, so that the end of the limiting plate abuts against the door to restrict the door. By configuring the limiting plate, transmission assembly, and drive assembly in the door lock device, the door can be locked when closed in the heating cavity, resulting in a high degree of automation and suitability for industrial applications.

[0004] Existing oven door lock structures rely on a combination of "limiting plates, transmission components, and drive components" to achieve locking, with the drive components involving sensors and electronic transmission parts. This type of design requires precise coordination between the mechanical transmission structure and the electronic control system, resulting in a large number of components and high assembly precision requirements, directly increasing manufacturing complexity. Simultaneously, electronic components (such as sensors) are sensitive to high temperatures, dust, and vibrations in industrial environments; prolonged use can lead to signal failure or transmission jamming due to environmental interference, causing door lock malfunctions. After a malfunction, repairs involving the coordinated operation of electronic and mechanical components require professional disassembly and troubleshooting, not only extending equipment downtime but also significantly increasing the cost of subsequent maintenance and component replacement. Furthermore, this door lock is located on the outer periphery of the oven and is relatively large. On the one hand, the peripheral installation exposes it directly to the complex environment of the industrial site, making it susceptible to collisions, oil contamination, or material scraping, which can cause the locking components to deform or jam, shortening its service life. On the other hand, the large size will occupy the operating space around the oven, especially in the case of dense equipment in the production workshop, hindering personnel operation or material handling and reducing space utilization. Therefore, we propose a single-point industrial cabinet door lock with a padlock hole. Utility Model Content

[0005] One of the technical problems this application aims to solve is that existing industrial oven door lock structures have a large number of parts, high maintenance costs, and large size. To address the aforementioned technical problems, this application provides a single-point industrial oven door lock with a padlock hole, comprising an industrial oven body and an operating side panel. An oven door is rotatably connected to one side of the industrial oven body, and a locking element is provided on the surface of the oven door. A limiting groove is provided on the side of the operating side panel near the oven door, and the locking element cooperates with the limiting groove to lock the oven door.

[0006] Preferably, the locking component includes a locking groove formed on the surface of the oven door. Two evenly distributed telescopic rods are horizontally installed inside the locking groove. A return spring is sleeved on the outer periphery of the telescopic rod with the smaller radius. A sliding groove is formed on both inner walls of the locking groove. A slider is provided on the outer side of the telescopic rod with the larger radius. The slider is slidably connected to the sliding groove. One side of the locking groove passes through the oven door. A limit block is provided at the end of the telescopic rod away from the return spring. The limit block is inserted into the limit groove.

[0007] Preferably, the grip includes a handle located on top of the slider, the surface of the oven door is provided with a mounting plate, the handle is mounted on top of the slider, and the surface of the mounting plate is provided with a groove for the handle to slide.

[0008] Preferably, the gripping component includes a rotating rod, a rotating frame, and a push rod disposed on one side of the slider. One side wall of the slider is rotatably connected to two evenly distributed rotating rods. The end of the rotating rod away from the slider is rotatably connected to the rotating frame. One end of the rotating frame is rotatably connected to the inner two side walls of the locking groove. The middle part of the end of the rotating frame away from the inner wall of the locking groove is fixedly connected to the push rod.

[0009] Preferably, the surface of the oven door is provided with a locking box, and the surface of the locking box has two evenly distributed rectangular openings, through which the rotating rod and the rotating frame pass.

[0010] Preferably, the surface of the locking box is provided with a second sliding groove, and a second limiting protrusion is slidably connected inside the second sliding groove. A lever is fixedly connected to the top of the second limiting protrusion, and a limiting square hole is provided on one side wall of the rotating frame. The second limiting protrusion is inserted into the limiting square hole.

[0011] Preferably, the limiting groove is an irregular inclined groove that expands inward, and the groove opening can accommodate the limiting insert block to enter and exit. A limiting protrusion is provided at the bottom of the inner cavity of the industrial oven body.

[0012] This utility model has at least the following beneficial effects: 1. This utility model achieves the locking function through a purely mechanical structure (telescopic rod, return spring, slider, rotating rod, etc.), eliminating the need for electronic components such as sensors and motors. This reduces the number of parts and the requirements for assembly precision, significantly lowering manufacturing complexity and costs. Furthermore, the mechanical structure is more resistant to high temperatures, dust, and vibrations in industrial environments, avoiding signal failures or transmission jams caused by interference with electronic components. This greatly reduces the probability of failure and minimizes the investment in subsequent maintenance and component replacement.

[0013] 2. The locking components (locking groove, telescopic rod, etc.) are built into the surface of the oven door, forming a compact structure with the locking box, avoiding the drawbacks of externally mounted door locks in existing technologies. On the one hand, this reduces the impact, contamination, or scratches on the locking components from the external environment, extending their service life; on the other hand, the compact size does not occupy too much operating space around the oven, making it particularly suitable for densely equipped production workshops, improving space utilization and avoiding obstruction to personnel operation or material handling.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figures 1-3 This utility model provides a technical solution: A single-point industrial oven door lock with a padlock hole includes an industrial oven body 1 and an operating side panel 2. An oven door 3 is rotatably connected to one side of the industrial oven body 1. A locking element 6 is provided on the surface of the oven door 3. A limiting groove 7 is provided on the side of the operating side panel 2 near the oven door 3. The locking element 6 and the limiting groove 7 cooperate to lock the oven door 3.

[0018] Furthermore, the locking component 6 includes a locking groove 8 formed on the surface of the oven door 3. Two evenly distributed telescopic rods 12 are horizontally installed inside the locking groove 8. A return spring 23 is sleeved on the outer periphery of the smaller radius end of the telescopic rod 12. Both inner walls of the locking groove 8 are provided with sliding grooves 9. A slider 10 is provided on the outer side of the larger radius side of the telescopic rod 12. The slider 10 is slidably connected to the sliding groove 9. One side of the locking groove 8 passes through the oven door 3. A limit plug 11 is provided at the end of the telescopic rod 12 away from the return spring 23. The limit plug 11 is inserted into the limit groove 7.

[0019] Furthermore, the gripping component includes a handle 4 disposed on the top of the slider 10, and a mounting plate 5 is disposed on the surface of the oven door 3. The handle 4 is mounted on the top of the slider 10, and the surface of the mounting plate 5 is provided with a groove for the handle 4 to slide.

[0020] When in use, when the oven door 3 is closed, push the handle 4 to slide along the groove on the surface of the mounting plate 5, causing the slider 10 to move synchronously within the sliding groove 9 of the locking groove 8. When the slider 10 moves, it pushes the telescopic rod 12 to retract into the locking groove 8. At this time, the return spring 23 sleeved on the outer periphery of the telescopic rod 12 is compressed. When the oven door 3 is rotated to be parallel to the side wall of the industrial oven body 1, release the handle 4, the return spring 23 returns to its original position, and the limiting insert 11 at the end of the telescopic rod 12 extends out with the telescopic rod 12 and inserts into the limiting groove 7 of the operating side table 2, thus completing the locking of the oven door 3.

[0021] Example 2 Please see Figures 4-8 This utility model provides a technical solution: Unlike embodiment one, this solution provides another implementation of the gripping component, which includes a rotating rod 14, a rotating frame 13, and a push rod 15 disposed on one side of the slider 10. One side wall of the slider 10 is rotatably connected to two evenly distributed rotating rods 14. The end of the rotating rod 14 away from the slider 10 is rotatably connected to the rotating frame 13. One end of the rotating frame 13 is rotatably connected to the inner two side walls of the locking groove 8. The middle part of the end of the rotating frame 13 away from the inner wall of the locking groove 8 is fixedly connected to the push rod 15.

[0022] Furthermore, a locking box 21 is provided on the surface of the oven door 3, and two evenly distributed rectangular openings 17 are provided on the surface of the locking box 21, through which the rotating rod 14 and the rotating frame 13 pass.

[0023] Furthermore, a second groove 18 is provided on the surface of the locking box 21, and a second limiting protrusion 20 is slidably connected inside the second groove 18. A lever plate 19 is fixedly connected to the top of the second limiting protrusion 20. A limiting square hole 22 is provided on one side wall of the rotating frame 13, and the second limiting protrusion 20 is inserted into the limiting square hole 22.

[0024] Furthermore, the groove of the limiting groove 7 is an irregular inclined groove that expands inward, and the groove opening can accommodate the entry and exit of the limiting insert 11. The bottom of the inner cavity of the industrial oven body 1 is provided with a limiting protrusion 16.

[0025] Unlike Embodiment 1, this utility model provides another technical solution based on Embodiment 1: When the rotating frame 13 is driven to rotate around the rotation point of the inner wall of the locking groove 8 by the push rod 15, the rotating frame 13 drives the slider 10 to move through the rotating rod 14 (the two ends of the rotating rod 14 are rotatably connected to the slider 10 and the rotating frame 13 respectively, forming a connecting rod structure), realizing the extension and retraction of the telescopic rod 12 and the limiting plug 11. The principle is the same as the basic locking process. Compared with the horizontal push handle 4 in Embodiment 1, this process uses an arc to push the push rod 15, which is more labor-saving and improves the convenience of operation. The locking box 21 is covered on the outside of the rotating frame 13 and the rotating rod 14, and the rectangular opening 17 on its surface provides movement space for the rotating rod 14 and the rotating frame 13. When the locking is in place, the sliding plate 19 drives the limiting protrusion 20 to move along the sliding groove 18, so that the limiting protrusion 20 Inserting the telescopic rod 12 into the limiting square hole 22 of the rotating frame 13 can lock the progress of the telescopic rod 12, thereby causing the limiting block 11 to retract into the locking groove 8, so that the oven door 3 is always open. This makes it convenient for staff to frequently take items out of the oven without having to frequently pull the push rod 15 to unlock the oven door 3, thus improving work efficiency. The irregular expansion of the inner side of the limiting groove 7 and the setting of the limiting protrusion 16 at the bottom of the inner side of the industrial oven body 1 are designed to prevent the oven door 3 from rotating too much and thus turning into the interior of the industrial oven body 1, damaging the oven, and thus serve as a limiting function. The push rod 15, rotating frame 13 and rotating rod 14 in this device are all made of high-strength alloy steel (such as No. 45 steel) to ensure that they are not easily worn or deformed during long-term reciprocating motion.
