Description

Technical Field

[0001] This utility model relates to a cabinet door, and more particularly to a freezer door with an opening angle limiting device. Background Technology

[0002] In existing freezers, to prevent the freezer door from opening too wide and causing damage, a door closer is usually installed at the upper part of the outside of the freezer. The opening angle of the freezer door is controlled by adjusting the opening angle of the door closer.

[0003] However, since the door closer is installed on the outside of the freezer, it is easy for the door closer to interfere with surrounding objects when the freezer door is opened, causing the freezer door to be unable to open to the set angle.

[0004] Furthermore, since the door closer is installed on the outside of the freezer and is directly connected to the door and body, it is easily subjected to external impacts during the freezer's turnover, causing damage to the door and body, increasing maintenance costs, and reducing the overall lifespan of the freezer. Utility Model Content

[0005] This utility model addresses the above-mentioned technical problems by providing a freezer door with an opening angle limiting device. This freezer door features a limiting seat plate installed at the lower end of the door. The limiting seat plate and the lower rotating connector together form an angle limiting device. When the door opens to a certain angle, the limiting seat plate contacts the lower rotating connector, thus limiting the opening of the door. This avoids the problems associated with external door closers, which can easily interfere with surrounding objects when the door is opened, preventing the door from opening to the set angle. It also avoids the technical problems of the door closer being easily damaged by external impacts during freezer turnover, as it is externally mounted and directly connected to the door and body. This reduces maintenance costs and extends the overall lifespan of the freezer.

[0006] Therefore, the technical solution of this utility model is a freezer door with an opening angle limiting device, including a door frame, a panel, and a sealing frame strip. The door frame is composed of multiple door frame bodies that are fixedly surrounded by each other. The front end of the door frame is fixedly connected to the panel, and the rear end of the door frame is fixedly connected to the sealing frame strip.

[0007] The upper and lower ends of one side of the door frame are respectively provided with an upper rotating connector and a lower rotating connector. One end of the upper rotating connector is rotatably connected to the upper end of the corresponding door frame, and one end of the lower rotating connector is rotatably connected to the lower end of the corresponding door frame.

[0008] A limiting seat plate is fixedly installed at the lower end of the door frame near the lower rotating connector. The limiting seat plate can rotate synchronously with the door frame.

[0009] Preferably, the limiting seat plate includes a limiting seat plate fixing section and a limiting seat plate limiting section, and the limiting seat plate fixing section is fixedly connected to the lower end of the door frame near the lower rotating connector.

[0010] Preferably, the limiting seat plate fixing section is provided with a limiting seat plate fixing hole, which is a longitudinal through hole. The limiting seat plate fixing section and the lower end of the door frame are locked and fixed together by screws passing through the limiting seat plate fixing hole on the limiting seat plate fixing section.

[0011] Preferably, the fixing hole of the limiting seat plate is elongated.

[0012] Preferably, the number of fixing holes in the limiting seat plate is multiple.

[0013] Preferably, a second magnet is fixedly provided on the outer end of the limiting section of the limiting seat plate.

[0014] Preferably, the lower rotating connector includes a lower rotating connector support section and a lower rotating connector fixing section. The upper end of the lower rotating connector support section is provided with a positioning pin, which is longitudinally arranged at the upper end of the lower rotating connector support section.

[0015] The lower rotating connector is connected to the door frame by inserting a positioning pin into the fixing hole at the lower end of the corresponding door frame, thereby achieving a rotating connection between the lower rotating connector and the lower end of the corresponding door frame.

[0016] A limiting groove is provided on one end of the lower rotating connector support section.

[0017] Preferably, the bottom of the lower rotating connector support section is fixedly provided with a first magnet at a position adjacent to the limiting groove, and the first magnet and the second magnet can attract each other.

[0018] Preferably, the positioning pin has a through hole inside, which extends longitudinally through the inside of the positioning pin.

[0019] The beneficial effect of this utility model is that by fixing a limiting seat plate at the lower end of the door frame near the lower rotating connector, when the door frame is opened outward, the limiting seat plate rotates synchronously with the door frame. When the door frame is opened to a certain angle, the limiting section of the limiting seat plate touches the limiting groove on the lower rotating connector, thereby limiting the door frame from opening further outward and realizing the function of limiting the opening angle of the door frame.

[0020] Furthermore, when the limiting section of the limiting plate on the limiting plate touches the limiting groove on the lower rotating connector, the first magnet and the second magnet attract each other, positioning the cabinet door at that position. At this time, the operator can release the cabinet door and use both hands to handle related tasks, such as organizing the items inside the cabinet, repairing the internal components of the cabinet, etc. Especially outdoors in windy conditions, the magnetic attraction to position the cabinet door makes it more convenient for the operator to perform related operations, making it convenient, quick, and safe.

[0021] Meanwhile, since the limiting plate is located inside the cabinet door, it will not interfere with surrounding objects when the cabinet door is opened, making it convenient to use. Attached Figure Description

[0035] The present invention will be further described below with reference to the embodiments.

[0036] pass Figures 1-11 It can be seen that the freezer door with the opening angle limiting device includes a door frame 1, a panel 2, and a sealing frame strip 6. The door frame 1 is composed of multiple door frame bodies 101 that are fixedly surrounded by each other. The front end of the door frame 1 is fixedly connected to the panel 2, and the rear end of the door frame 1 is fixedly connected to the sealing frame strip 6.

[0037] Panel 2 can be made of transparent or opaque materials depending on actual usage needs, and different materials, structures and colors can be selected, such as frosted materials, plastic materials, etc. When panel 2 is transparent hollow glass, it is convenient for operators to see the status of the items inside the cabinet.

[0038] The upper and lower ends of one side of the door frame 1 are respectively provided with an upper rotating connector 3 and a lower rotating connector 4. One end of the upper rotating connector 3 is rotatably connected to the upper end of the corresponding door frame 1, and the other end of the upper rotating connector 3 is fixedly connected to the corresponding position of the upper part of the cabinet. One end of the lower rotating connector 4 is rotatably connected to the lower end of the corresponding door frame 1, and the other end of the lower rotating connector 4 is fixedly connected to the corresponding position of the lower part of the cabinet. The door frame 1 can be opened and closed under the rotational support of the upper rotating connector 3 and the lower rotating connector 4.

[0039] A limiting plate 5 is fixedly provided at the lower end of the door frame 1 near the lower rotating connector 4. The limiting plate 5 can rotate synchronously with the door frame 1. When the door frame 1 is opened to a certain angle, the limiting plate 5 touches the lower rotating connector 4, thereby limiting the door frame 1 from opening further outward, thus achieving the function of limiting the opening angle of the door frame 1.

[0040] The limiting seat plate 5 includes a limiting seat plate fixing section 501 and a limiting seat plate limiting section 502. The limiting seat plate fixing section 501 is fixedly connected to the lower end of the door frame 1 near the lower rotating connector 4.

[0041] The limiting seat plate fixing section 501 is provided with a limiting seat plate fixing hole 504. The limiting seat plate fixing hole 504 is a through hole that runs longitudinally through the door frame 1. The limiting seat plate fixing section 501 and the lower end of the door frame 1 are locked and fixed by screws passing through the limiting seat plate fixing hole 504 on the limiting seat plate fixing section 501. This enables the limiting seat plate 5 to be quickly disassembled and assembled, which is convenient for initial assembly and subsequent maintenance and disassembly.

[0042] The limiting seat plate fixing hole 504 is elongated, which enables the limiting seat plate 5 to move back and forth. By changing the back and forth position of the limiting seat plate 5 on the door frame 1, the travel distance between the limiting seat plate 5 and the lower rotating connector 4 is changed, and the maximum opening angle of the door frame 1 can be adjusted according to actual usage requirements.

[0043] The number of fixing holes 504 on the limiting seat plate is multiple, that is, it is fixed by multiple screws, which can increase the stability of the connection between the limiting seat plate 5 and the door frame 1. If the limiting seat plate fixing hole 504 is set to one and only locked by one screw, the screw is prone to loosening during the long-term opening and closing of the cabinet door, which will cause the limiting seat plate 5 to loosen and affect the normal use of the cabinet door.

[0044] The lower rotating connector 4 includes a lower rotating connector support section 401 and a lower rotating connector fixing section 403. The upper end of the lower rotating connector support section 401 is provided with a positioning pin 402, which is longitudinally arranged at the upper end of the lower rotating connector support section 401.

[0045] The lower rotating connector 4 is connected to the door frame 1 by a positioning pin 402 inserted into the fixing hole at the lower end of the corresponding door frame 1, thereby achieving a rotating connection between the lower rotating connector 4 and the lower end of the corresponding door frame 1. The fixing section 403 of the lower rotating connector is fixedly connected to the corresponding position at the lower part of the cabinet.

[0046] A limiting groove 404 is provided on one end of the lower rotating connector support section 401.

[0047] A second magnet 503 is fixedly provided on the outer end of the limiting section 502 of the limiting seat plate, and a first magnet 405 is fixedly provided at the bottom of the lower rotating connector support section 401 at a position adjacent to the limiting groove 404. The first magnet 405 and the second magnet 503 can attract each other.

[0048] When in use, the door frame 1 opens outward, and the limiting seat plate 5 rotates synchronously with the door frame 1. When the door frame 1 opens to a certain angle, the limiting segment 502 on the limiting seat plate 5 touches the limiting groove 404 on the lower rotating connector 4, thereby limiting the door frame 1 from opening further outward and realizing the limiting function of the opening angle of the door frame 1.

[0049] Furthermore, when the limiting plate limiting segment 502 on the limiting plate 5 touches the limiting groove 404 on the lower rotating connector 4, the first magnet 405 and the second magnet 503 attract each other, positioning the cabinet door at that position. At this time, the operator can release the cabinet door and handle related matters with both hands, such as organizing the items inside the cabinet, repairing the internal components of the cabinet, etc. Especially outdoors in windy conditions, the magnetic attraction to position the cabinet door makes it more convenient for the operator to perform related operations, which is convenient, quick, and has a high safety factor.

[0050] The positioning pin 402 has a through hole 406 inside, which is longitudinally arranged inside the positioning pin 402. This allows for the assembly and use of the upper and lower double-door freezer. The bushing at the upper end of the lower door is inserted into the through hole 406 from bottom to top. The lower end of the lower door can adopt the relevant structure of this patent.

[0051] A door frame groove 102 is provided on the inner end of the door frame body 101. The sealing frame strip 6 is provided with a first fixing section 601, a connecting section 602, a second fixing section 603, a compression section 604, and a contact sealing section 605 in sequence from front to back. The widths of the first fixing section 601 and the second fixing section 603 are both greater than the width of the connecting section 602. The upper and lower positions of the first fixing section 601 and the second fixing section 603 are respectively provided with sealing frame fixing grooves 606 between them and the upper and lower ends of the adjacent connecting section 602.

[0052] The first fixing section 601 of the sealing frame strip 6 can be inserted into the door frame groove 102 to achieve a fixed connection between the sealing frame strip 6 and the door frame 1. The first fixing section 601 of the sealing frame strip is conical in shape. The conical structure of the first fixing section 601 of the sealing frame strip can guide the operator during the process of inserting the first fixing section 601 of the sealing frame strip into the door frame groove 102, making it easier for the operator to insert the first fixing section 601 of the sealing frame strip into the door frame groove 102, further reducing the installation intensity and increasing work efficiency.

[0053] This door opening angle limiting device can be applied to different cabinet doors, such as double doors, top and bottom doors, and multi-door cabinets, and has a wide range of applications.

[0054] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
