During maintenance of internal components, if the door swings due to external forces (such as wind or accidental contact), it could cause collision injuries to maintenance personnel positioned in front of or behind the door, posing a safety hazard. Furthermore, when multiple racks are arranged side-by-side, simultaneous opening of doors in adjacent racks could lead to door-to-door interference. Utility Model Content

[0003] The purpose of this utility model is to provide a door opening angle limiting structure and cabinet, which aims to solve the technical problem that the cabinet door cannot be positioned after it is opened in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a door opening angle limiting structure, comprising:

[0005] A limiting component is fixed to the back of the door panel; the limiting component is provided with a slide rail, and the limiting component is also provided with multiple positioning grooves, which are distributed at intervals along the extension direction of the slide rail;

[0012] In some embodiments, the locking member further includes an abutting portion, the abutting portion, the inserting portion, and the connecting portion are sequentially connected, and the radii of the abutting portion, the inserting portion, and the connecting portion decrease sequentially; when the inserting portion is confined within the positioning groove, the abutting portion abuts against the limiting member.

[0013] In one possible implementation, the limiting member is an L-shaped plate, the vertical portion of which is fixed to the back of the door panel; the slide rail and the positioning groove are disposed on the horizontal portion of the L-shaped plate.

[0014] In one possible implementation, the door opening angle limiting structure further includes:

[0015] A fixed base is fixedly installed on the door frame; one end of the support rod is hinged to the fixed base.

[0016] The beneficial effects of the door opening angle limiting structure provided by this utility model are as follows: Compared with the prior art, the door opening angle limiting structure of this utility model allows the support rod and the limiting component to slide together during the opening and closing of the door panel, and the support rod supports the door panel to prevent the door panel from swinging too fast and causing a collision; when the locking component is inserted and limited in one of the positioning slots, the support rod and the limiting component are fixed, the door panel opens to the preset angle, and the position is fixed and cannot swing, thereby preventing the door panel from suddenly swinging and colliding with maintenance personnel under the action of external force; in addition, the limiting component has multiple positioning slots, each positioning slot corresponding to a door panel opening angle, and the opening angle of the door panel is determined, thereby avoiding collision interference between the door panels of two adjacent cabinets.

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1 The opening angle limiting structure provided by this utility model will now be described. The opening angle limiting structure includes a limiting member 1, a support rod 2, and a locking member 3. The limiting member 1 is fixed to the back of the door panel 5; the limiting member 1 is provided with a slide rail 11, and the limiting member 1 is also provided with a plurality of positioning grooves 12, which are spaced apart along the extension direction of the slide rail 11; one end of the support rod 2 is hinged to the door frame 6, and the other end is slidably connected to the slide rail 11; the locking member 3 is connected to the sliding end of the support rod 2; the locking member 3 can be limited to any one of the positioning grooves 12, so that the support rod 2 is fixed relative to the limiting member 1.

[0027] The vertical side of door panel 5 is hinged to the vertical side of door frame 6. Limiting member 1 is fixed to the back of door panel 5, near the hinge side. The hinged end of support rod 2 is fixed to the bottom and / or top of door frame 6, near the hinge side. When door panel 5 is closed, limiting member 1 and support rod 2 are stacked and parallel. When door panel 5 is opened, limiting member 1 and door panel 5 form an angle, which is the opening angle of door panel 5. Because this door opening angle limiting structure is located on the hinge side of door panel 5 and door frame 6, it occupies a small amount of space and will not affect maintenance operations after the door is opened.

[0028] The limiting member 1 is provided with a slide rail 11, and the support rod 2 is slidably connected to the limiting member 1 through the slide rail 11. It should be noted that the support rod 2 can be assembled and connected to the limiting member 1 through the slide rail 11, or it can simply slide on the slide rail 11 and be connected to the limiting member 1 through the locking member 3.

[0029] The limiting member 1 also has multiple positioning grooves 12, each positioning groove 12 corresponding to a door panel 5 opening angle. Therefore, the door panel 5 has at least two preset opening angles.

[0030] The locking member 3 is connected to the sliding end of the support rod 2, and the locking member 3 has a degree of freedom to move perpendicular to the sliding direction. In other words, the locking member 3 has two fixed positions on the support rod 2. Specifically, when the door panel 5 is opened or closed, the limiting member 1 is located in the first fixed position, away from the slide rail 11, and slides with the support rod 2; after the door panel 5 is opened to a specific angle, the limiting member 1 is in the second fixed position and is embedded in the limiting positioning groove 12 to fix the support rod 2 and the limiting member 1.

[0031] It should be noted that the movement of locking element 3 is controlled manually.

[0032] The specific operation process for opening and closing door panel 5 is as follows:

[0033] When the operator opens the door panel 5, the limiting member 1 moves with the door panel 5, and one end of the support rod 2 slides on the limiting member 1. When it is necessary to fix the opening angle of the door panel 5, the operator adjusts the position of the door panel 5 so that the locking member 3 aligns with one of the positioning grooves 12, and then moves the locking member 3 so that it is embedded in the positioning groove 12. When the operator wants to close the door panel 5, he first moves the locking member 3 in the opposite direction to disengage it from the positioning groove 12, and then pushes the door panel 5 to close.

[0034] Compared with the prior art, the door opening angle limiting structure provided by this utility model has the following advantages: during the opening and closing process of the door panel 5, the support rod 2 and the limiting member 1 slide together, and the support rod 2 supports the door panel 5 to prevent the door panel 5 from swinging too fast and causing a collision; when the locking member 3 is inserted into one of the positioning grooves 12, the support rod 2 and the limiting member 1 are fixed, the door panel 5 is opened to the preset angle, and the position is fixed and cannot swing, thereby avoiding the door panel 5 from suddenly swinging and colliding with maintenance personnel under the action of external force; in addition, the limiting member 1 has multiple positioning grooves 12, each positioning groove 12 corresponds to a door panel 5 opening angle, and the opening angle of the door panel 5 is determined, thereby avoiding collision interference between two adjacent cabinet door panels 5.

[0035] In some embodiments, the slide rail 11 may be adopted as follows: Figure 2 The structure shown is described in the following document. Figure 2 The slide rail 11 has a strip-shaped hole that extends along the width of the door panel 5 and passes through the height of the door panel 5.

[0036] The slide rail 11 is designed with a strip-shaped hole, which simplifies the structure of the limiting member 1. Only a hole needs to be made on the limiting member 1, eliminating the need for a complex track design. The strip-shaped hole runs through the height of the door panel 5, meaning that the limiting member 1 has a plate surface perpendicular to the back of the door panel 5. The support rod 2 slides above or below the strip-shaped hole, which simplifies the sliding method and ensures the sliding stability of the support rod 2 and the limiting member 1.

[0037] Preferably, please refer to Figure 2 Based on the above embodiment, the positioning groove 12 is formed on the wall of the slotted hole along its extension direction. The wall of the slotted hole has multiple concave curved surfaces, which are spaced apart along the length of the slotted hole. Each concave curved surface encloses a positioning groove 12. The positioning groove 12 also extends through the door panel 5 along its height direction.

[0038] It should be noted that multiple concave curved surfaces can be provided on one side of the hole wall of the strip hole, or multiple concave curved surfaces can be provided on both sides of the hole wall. Among them, two concave curved surfaces corresponding to each other in the width direction of the strip hole form a positioning groove 12.

[0039] The positioning groove 12 is formed on the wall of the strip hole, which can further simplify the structure of the limiting member 1 and make the limiting member 1 easier to manufacture.

[0040] In some embodiments, the support rod 2 and the limiting member 1 can be connected by, for example, Figure 1 The structure shown is described in the following document. Figure 1 The sliding end of the support rod 2 is located below the strip hole; one end of the locking member 3 passes downward through the strip hole and is connected to the support rod 2.

[0041] Preferably, there is a gap between the support rod 2 and the limiting member 1, so that friction between the support rod 2 and the limiting member 1 can be avoided during the swinging of the door panel 5, thus preventing abnormal noise.

[0042] The locking component 3 not only serves to fix the support rod 2, but also serves to connect the support rod 2 and the limiting component 1. The upper end of the locking component 3 is located above the slotted hole, and the lower end passes through the slotted hole and connects to the support rod 2, thereby limiting the support rod 2 to be below the slotted hole.

[0043] It should be noted that when the limiting member 1 is in the first fixed position, it will not interfere with the strip hole and can slide with the support rod 2; when the limiting member 1 is in the second fixed position, it is embedded in the positioning groove 12.

[0044] In some embodiments, the locking element 3 described above may be as follows: Figure 3 The structure shown is described in the following document. Figure 3 The locking component 3 includes a connecting part 31 and an insert part 32 connected in sequence; the connecting part 31 is threadedly connected to or inserted into the sliding end of the support rod 2; the insert part 32 can be confined within any one of the positioning grooves 12.

[0045] Taking the assembly direction of the locking member 3 as a reference, the insert part 32 and the connecting part 31 are connected sequentially from top to bottom. The connecting part 31 passes downward through the strip hole and is used to connect with the sliding end of the support rod 2 so as to limit the upper and lower positions between the limiting member 1 and the support rod 2.

[0046] Specifically, the connecting part 31 can be inserted into the sliding end of the support rod 2. By manually pressing and pulling the upper end of the locking member 3, the locking member 3 can be switched between the first fixed position and the second fixed position. The connecting part 31 and the support rod 2 can also be threaded together. The connecting part 31 is provided with external threads, and the sliding end of the support rod 2 is provided with internal threaded holes. By manually rotating the upper end of the connecting part 31, the locking member 3 can be switched between the first fixed position and the second fixed position.

[0047] In the first fixed position, the insert 32 is located above the strip hole. The insert 32 does not interfere with the strip hole and the positioning groove 12, and does not affect the sliding of the support rod 2. In the second fixed position, the insert 32 is at least partially embedded in the positioning groove 12. The outer peripheral surface of the insert 32 abuts against the groove wall of the positioning groove 12, forming a limit in the sliding direction. The support rod 2 cannot slide, thereby ensuring that the door panel 5 opens to the preset angle.

[0048] Please see Figure 3 Based on the above embodiments, the locking member 3 also includes an abutment portion 33, the abutment portion 33, the insert portion 32 and the connecting portion 31 are connected sequentially from top to bottom, and the radii of the abutment portion 33, the insert portion 32 and the connecting portion 31 decrease sequentially; when the insert portion 32 is confined within the positioning groove 12, the abutment portion 33 abuts against the upper surface of the limiting member 1.

[0049] The abutment part 33 serves to determine the second fixed position. When the locking member 3 is pressed down or rotated until the abutment part 33 abuts against the upper surface of the limiting member 1, it indicates that the insert part 32 is embedded in the positioning groove 12.

[0050] In addition, the abutment part 33 also serves to facilitate the operation of the locking part 3 and to prevent the locking part 3 from being pressed too far into place and unable to return to its original position.

[0051] In some embodiments, the limiting member 1 may be as follows: Figure 2 The structure shown is described in the following document. Figure 2 The limiting component 1 is an L-shaped plate, and the vertical part of the L-shaped plate is fixed to the back of the door panel 5; the slide rail 11 is set in the horizontal part of the L-shaped plate.

[0052] The L-shaped panel has a simple structure and is easy to manufacture. It is convenient to set the slide rail 11 and positioning groove 12, and it is also convenient to install on the door panel 5.

[0053] In some embodiments, the above-mentioned door opening angle limiting structure can also adopt, for example, Figure 1 The structure shown is described in the following document. Figure 1 The door opening angle limiting structure also includes a fixed seat 4. The fixed seat 4 is fixedly mounted on the door frame 6; one end of the support rod 2 is hinged to the fixed seat 4.

[0054] The fixed base 4 serves to fix and support the strut 2, thereby raising the strut 2 and increasing the fixing strength of the hinge end of the strut 2, thus ensuring good stability when the strut 2 swings.

[0055] Based on the same inventive concept, this application also provides a cabinet, including a door panel 5, a door frame 6, and the aforementioned door opening angle limiting structure.

[0056] The cabinet provided by this utility model has a sliding fit between the support rod 2 and the limiting member 1 during the opening and closing of the door panel 5, and the support rod 2 supports the door panel 5 to prevent the door panel 5 from swinging too fast and causing a collision. When the locking member 3 is inserted and limited in one of the positioning slots 12, the support rod 2 and the limiting member 1 are fixed, the door panel 5 is opened to a preset angle, and the position is fixed and cannot swing, thereby preventing the door panel 5 from suddenly swinging and colliding with maintenance personnel under the action of external force. In addition, the limiting member 1 has multiple positioning slots 12, each positioning slot 12 corresponds to a door panel 5 opening angle, and the opening angle of the door panel 5 is determined, thereby preventing the door panels 5 of two adjacent cabinets from colliding and interfering.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
