Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0022] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0023] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0024] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] See Figures 1-3 This utility model provides a technical solution: a cell door, including a door frame 1, the door frame 1 including two vertical rods 11, two connecting rods 12, a horizontal rod 13, and a support rod 14. One of the two connecting rods 12 connects to the bottom ends of the two vertical rods 11, and the other connects to the top ends of the two vertical rods 11. The two ends of the horizontal rod 13 are respectively connected to the two vertical rods 11, and the horizontal rod 13 is set at the upper end of the vertical rods 11. A drive mounting area 2 is provided between the horizontal rod 13 and the upper connecting rod 12. One end of the support rod 14 is connected to the horizontal rod 13, and the other end is connected to the lower connecting rod 14. The connecting rod 12 connects and the support rod 14 divides the area enclosed by the vertical rod 11 and the connecting rod 12 into a door installation area and a closed area. The door installation area is provided with a sliding inner door 3 and an outer door 4 hinged to the support rod 14. The connecting rod 12 and the horizontal rod 13 at the bottom are both provided with guide rails 121. The inner door 3 is provided with a pulley that cooperates with the guide rail 121. The vertical rod 11 on the left side is provided with a groove 111 for the inner door 3 to be inserted. The vertical rod 11 is also provided with a gate stop 112 at the edge of the groove 111. The outer door 4 is also provided with an observation window 41 and a lock body 42. This utility model has a simple structure and ingenious design. The main feature is that the vertical rod 11 is made by bending and welding the iron plate 5. The groove 111, which is integrated with the vertical rod 11, can be bent out as needed, reducing the welding process and the gap between the joints, improving the stability of the overall structure. Furthermore, the gap between the inner door 3 and the door frame 1 can be hidden in the groove 111, which greatly improves the difficulty of damaging the overall cell door and its security.

[0027] The vertical rod 11 is made by bending and welding iron plate 5. The weld joint has a butt flange. The bending method can effectively reduce the butt weld seam, while also making it more integral. It can also set more protective structures without welding (such as groove 111). The structure is more stable and not easily damaged. Furthermore, by butt flange welding, the weld seam can be effectively reduced, improving the door's security performance.

[0028] Preferably, the outer door 4 is provided with multiple crisscrossing reinforcing ribs. This further increases the overall structural strength of the outer door 4, making it more impact-resistant.

[0029] Preferably, the enclosed area is sealed by an iron plate 5, and multiple reinforcing columns 51 are provided on the back of the iron plate 5. These columns support the iron plate 5 and effectively strengthen the overall structural strength of the door frame 1.

[0030] Preferably, the outer door 4 is provided with a corner stop 43 at the mating end with the vertical rod 11. This improves the overall aesthetics and also seals the gap between the inner door 3 and the vertical rod 11, providing a protective function.

[0031] Preferably, the drive mounting area 2 is provided with a power mechanism, which is used to drive the inner door 3 to move back and forth along the guide rail 121.

[0032] Preferably, the guide rail 121 is provided with a limiting block 122. This limits the movement trajectory of the inner door 3, prevents inertial collisions between the inner door 3 and the vertical rod 11, provides effective protection, and extends the service life of the door.

[0033] Preferably, the observation window 41 is provided with a baffle plate, and the inner side of the observation window 41 is provided with a baffle groove. When the baffle plate closes the observation window 41, it is embedded in the baffle groove. This can effectively hide the gap between the baffle plate and the observation window 41, increase the difficulty of prying it open, and improve security.
