Description

Technical Field

[0001] The utility model belongs to the technical field of the structure of cash transport vehicles, and particularly relates to a hanging sliding door mechanism. Background Art

[0002] In the design of cash transport vehicles, sliding doors are usually provided on the front panel of the cash transport compartment. This design has many advantages. First of all, the sliding door can effectively save the space inside the vehicle. Compared with traditional opening and closing doors, the sliding door does not require additional opening space, so it is more suitable in a narrow environment. Especially when the space inside the vehicle is limited, the space inside the compartment can be utilized to the maximum. In addition, the installation and maintenance of the sliding door are relatively convenient, the structure is simple, and it will not affect the layout of other equipment inside the vehicle. In terms of operation, the use of the sliding door is more flexible, which can facilitate the rapid entry and exit of personnel. However, the existing sliding door structure has the following problems: First, the door panel of the original sliding door is mainly guided by the upper rollers and supported by the lower rollers. Since the lower rollers are in single-point contact and support, the contact area is small, and the door is prone to swing back and forth and is not easy to keep the door panel vertical. Second, most of the existing doors are provided with bottom rails to cooperate with the rollers to maintain the verticality of the door panel. Due to the entire weight of the door on the bottom rail during long-term operation, it is easy to wear and deform, which will affect the normal operation of the door and will also generate gaps, resulting in varying degrees of abnormal noise during vehicle driving, affecting the comfort of the passengers and drivers.

[0003] In view of the above-mentioned existing technology, it is necessary to reasonably improve the structure of the existing sliding door mechanism. For this reason, the applicant has made a beneficial design, and the technical solution to be introduced below is generated under this background. Summary of the Utility Model

Detailed implementation manners

[0020] The following will be described in detail by way of embodiments. However, the descriptions of the embodiments are not limitations on the solutions of the present invention. Any formal but non-substantive equivalent transformation made based on the concept of the present invention should be regarded as falling within the scope of the technical solutions of the present invention.

[0021] In the following descriptions, any directional or positional concepts such as up, down, left, right, front, and back are based on the positions shown in the respective drawings, and thus cannot be understood as special limitations on the technical solutions provided by the present invention.

[0022] Please refer to Figure 1 and in combination with Figures 2 to 4 , which shows a hanging sliding door mechanism, including a front plate 4 of the cash transport compartment. A door panel assembly 2 is provided on one side of the front plate 4 of the cash transport compartment. An upper roller assembly 1 is provided above the door panel assembly 2, and a lower chute assembly 3 is provided below the door panel assembly 2;

[0023] The upper roller assembly 1 includes four upper roller shafts 15 and an upper guide rail 11. The upper guide rail 11 is fixedly connected to the inner wall of the front plate 4 of the cash transport compartment. A C-shaped groove 16 is provided inside the upper guide rail 11. One end of the upper roller shaft 15 is located inside the C-shaped groove 16. A rolling bearing 14 is rotatably connected to the end of the upper roller shaft 15 located in the C-shaped groove 16. The rolling bearing 14 is slidably connected to the C-shaped groove 16. The other end of the upper roller shaft 15 is fixedly connected to a connecting plate 12. A thrust collar 13 is sleeved on the upper roller shaft 15. Both ends of the thrust collar 13 respectively abut against the connecting plate 12 and the upper roller shaft 15;

[0024] The lower chute assembly 3 includes a lower guide rail 31. The bottom of the lower guide rail 31 is fixedly connected to the front plate 4 of the cash transport compartment.

[0025] In use, the combination design of the upper roller assembly 1 and the upper guide rail 11 provides excellent stability and durability in the sliding door system. Specifically, the upper roller composed of the upper roller shaft 15 and the rolling bearing 14 is located in the C-shaped groove 16 of the upper guide rail 11, which not only effectively avoids the problem of displacement when the sliding door moves left and right, but also utilizes the C-shaped structure of the upper guide rail 11 to provide excellent anti-bending and anti-torsion capabilities. This structure can withstand large loads, ensuring that the sliding door remains stable and operates smoothly during long-term use.

[0026] In addition, the C-shaped design of the upper guide rail 11 also makes the installation easier. By fixing the guide rail to the base by bolts or welding, the installation steps are simplified, improving the construction efficiency. This structural design also has high convenience. During cleaning and maintenance, no complex operations are required, and users can easily perform regular inspections and maintenance, extending the service life of the system.

[0027] During the operation of the sliding door, the upper roller assembly 1 plays an important role. By suspending the door panel, the upper roller assembly 1 ensures the stability of the door panel and is not prone to swinging. When used in conjunction with the lower chute assembly 3 on the ground, the lower chute assembly 3 can operate smoothly in a vertical plane, further enhancing the stability of the system.

[0028] Compared with the traditional sliding connection, the upper roller assembly 1 replaces the flexible connection with a rigid-contact rolling bearing 14 and uses rolling friction instead of sliding friction, greatly reducing the moving resistance. Since the rolling friction coefficient is significantly smaller than the sliding friction coefficient, this design not only makes the sliding door move more lightly and smoothly, but also generates very low noise, significantly improving the user experience. Combining the above advantages, the design of the upper roller assembly 1 greatly extends the service life of the sliding door, enabling it to maintain efficient and stable performance in a high-frequency use environment.

[0029] Please continue to refer to Figure 4 , two chute plates 32 are slidably connected to the top of the lower guide rail 31, and the top of the chute plates 32 is fixedly connected to the bottom of the door panel assembly 2. The two chute plates 32 are respectively located on both sides of the bottom of the door panel assembly 2.

[0030] In this embodiment, compared with the traditional single-roller guiding structure, the door panel assembly 2 has significant technical advantages, especially in terms of the stability and accuracy of the sliding door system. This improved structure ensures that the door panel assembly 2 always stays on the correct track during the sliding process through the ingenious cooperation of the two chute plates 32. It effectively avoids the situation of the door body deviating from the direction during operation, reduces the risk of the door body tilting or jamming, and thus greatly reduces the frequency of adjustment and maintenance by users during use. As a result, the operation of the door body is more smooth and stable, and at the same time, the overall durability and reliability of the system are also improved.

[0031] In addition, the lower chute assembly 3 is made of high-quality nylon material, which is outstanding in terms of wear resistance, impact resistance and self-lubrication, and is particularly suitable for systems with high loads and frequent movements. The nylon material can not only effectively eliminate the shaking caused by vibration during the operation of the sliding door, but also greatly reduce the friction noise, achieving an excellent sound insulation effect.

[0032] This structural design not only solves the common noise and direction deviation problems in traditional sliding door systems, but also improves the overall performance of the sliding door. The combination of the door panel assembly 2 and the lower chute assembly 3 forms a stable and efficient guiding system, ensuring the smooth operation and precise control of the door body during use. At the same time, the innovative design of using nylon rollers effectively extends the service life of the rollers and guide rails, reduces the replacement and maintenance costs caused by wear, and further improves the cost performance of the sliding door system.

[0033] Please refer to Figure 1 and in combination with Figure 3 , the four upper roller shafts 15 are grouped in pairs, and the two groups of upper roller shafts 15 are respectively located on both sides above the door panel assembly 2. The bottom of the connecting plate 12 is fixedly connected to the top of the door panel assembly 2.

[0034] In this embodiment, during the sliding process, the protrusion 33 provided on the top of the lower guide rail 31 and the positioning groove 34 generate relative sliding, and the structural design of the protrusion 33 plays a key role in the sliding door system. First of all, the unique shape of the protrusion 33 allows the door panel assembly 2 to automatically adjust the contact angle with the guide rail during operation. This automatic adjustment function greatly reduces the jamming phenomenon caused by the deformation of the guide rail or the door panel assembly 2 due to uneven installation, environmental changes or long-term use. Through this dynamic adaptation mechanism, the sliding process of the door panel can be kept smooth, and the stability of the system can be ensured even under complex installation conditions.

[0035] In addition, the cooperation between the protrusion 33 and the positioning groove 34 results in a relatively small contact area. Compared with the traditional design, this structure significantly reduces the wear caused by friction during the sliding process. Since friction is the main cause of the aging and damage of the guide rail and the door panel assembly 2, the design of the protrusion 33 effectively extends the service life of the guide rail and the door body by reducing the friction contact area. Less friction not only means a longer service life of the system, but also reduces the frequency of daily maintenance and repair, thus improving the cost performance of the entire sliding door system.

[0036] Meanwhile, the structural design of the protrusion 33 has excellent pressure-bearing dispersion ability. During the sliding process of the sliding door, the weight of the door body often concentrates on the guide rail, and the unique design of the protrusion 33 can effectively disperse the pressure applied to the guide rail. This pressure-dispersing effect not only makes the door panel more stable during sliding but also further reduces the risk of the door body tilting or shifting, ensuring that the sliding door maintains a horizontal and precise sliding trajectory during use.

[0037] In summary, the design of the protrusion 33 improves the performance of the sliding door system in multiple aspects. Through its automatic adjustment function, it reduces jamming caused by installation problems or environmental changes; by reducing friction, it extends the service life of the system; by dispersing pressure, it enhances the sliding stability of the door body. Combining these advantages, the protrusion 33 provides the sliding door system with longer durability and a smoother user experience, making it a key component in the design of high-performance sliding door systems.

[0038] Furthermore, a protrusion 33 is provided at the top of the lower guide rail 31, and a positioning groove 34 is opened at the center of the bottom of the chute plate 32. The top end of the protrusion 33 is located inside the positioning groove 34.

[0039] Please refer to Figures 1 to 4 , the applicant briefly describes the working principle of the present utility model: The upper roller composed of the upper roller shaft 15 and the rolling bearing 14 is located in the C-shaped groove 16 of the upper guide rail 11. This not only prevents the sliding door from dislocating when moving left and right but also because the upper guide rail 11 is of a C-shaped structure as a whole, which has strong anti-bending and anti-torsion capabilities and can effectively bear a large load. In addition, it is convenient to adjust during installation and can be fixed to the base by bolts or welding, further simplifying the installation process. The C-shaped structure design makes cleaning and maintenance relatively simple and is convenient for regular inspection and maintenance.

[0040] The upper roller assembly 1 makes the door panel more stable after being suspended and not prone to swinging, and cooperates with the lower chute assembly 3 on the ground to ensure that the lower chute assembly 3 operates in the vertical plane. The upper roller assembly 1 uses the rigid contact of bearings to replace the flexible connection and rolling to replace sliding. Since the rolling friction coefficient is smaller than the sliding friction coefficient, the moving resistance during the sliding of the door is smaller, the movement is more convenient and the noise is smaller, thereby extending the service life of the door. Compared with the traditional single-roller guiding structure, the new door panel assembly 2 significantly improves the stability and accuracy of the sliding door. Through the cooperation of the two chute plates 32, it is ensured that the door panel assembly 2 always stays on the correct track during the sliding process, avoiding the door body from deviating from the direction and reducing the complexity of adjustment during use.

[0041] During the sliding process, the protrusion 33 provided on the top of the lower guide rail 31 slides relative to the positioning groove 34. The design of the protrusion 33 allows the door panel assembly 2 to automatically adjust the contact angle with the guide rail, reducing the jamming phenomenon caused by uneven installation or deformation, thereby improving the sliding smoothness. Due to the relatively small contact area, the design of the protrusion 33 can reduce the wear caused by friction during the sliding process, thereby extending the service life of the guide rail and the door body. In addition, the protrusion 33 can effectively disperse the pressure applied to the guide rail, making the door body move more stably and reducing the risk of tilting or deviation.

[0042] In summary, the technical solution provided by the present utility model makes up for the deficiencies in the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
