[0001] This utility model relates to the field of door panel limiting technology, specifically to a door panel limiting device. Background Technology

[0002] Server racks mainly consist of a cabinet body and door panels, with the door panels used to open or close the cabinet body. In existing technology, the cabinet door and door panel are connected by hinges. When the door panel is opened, because the hinges have no stop structure, when the door panel is opened at too large an angle, the door panel will collide hard with the cabinet body, which not only easily generates noise but also easily damages the cabinet body and door panel. Utility Model Content

[0003] The present invention aims to provide a door panel limiting device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a door panel limiting device, comprising a limiting rod and a sliding groove component. The first end of the limiting rod is hinged to the cabinet body, and the second end is fitted with a stepped bolt. The sliding groove component is fixedly installed on the inner side of the door panel. The sliding groove component is provided with an elongated slot, and at least one circular hole is provided along the length of the elongated slot. The diameter of the circular hole is larger than the width of the elongated slot. The stepped bolt slides and engages with the elongated slot to drive the limiting rod to swing. The stepped bolt engages with the circular hole to limit the limiting rod and the sliding groove component to form a positioning support.

[0005] Preferably, the stepped bolt includes a first cylinder, a second cylinder, a third cylinder, and a fourth cylinder whose diameters gradually decrease from top to bottom. The second end of the limiting rod has a threaded hole, and the surface of the fourth cylinder has an external thread. The second end of the limiting rod is located below the sliding groove, and the fourth cylinder passes through the long slot from top to bottom and is threadedly connected to the threaded hole of the limiting rod.

[0006] Preferably, the diameter of the first cylinder is larger than the diameter of the circular hole, the diameter of the second cylinder is smaller than the diameter of the circular hole, the diameter of the second cylinder is larger than the width of the elongated slot, and the diameters of the third and fourth cylinders are smaller than the width of the elongated slot.

[0007] Preferably, the diameter of the bottom end of the second, third, or fourth cylinder gradually decreases from top to bottom.

[0008] Preferably, there is one round hole, located at one end of the elongated slot.

[0009] Preferably, there are two round holes, located at the end and middle of the long slot, respectively.

[0010] Preferably, it also includes an inverted U-shaped fastener for fixing to the cabinet, and the first end of the limiting rod is hinged to the fastener.

[0011] Preferably, the longitudinal section of the sliding groove is U-shaped, including a first longitudinal plate, a second longitudinal plate, and a transverse plate connected between the bottom end of the first longitudinal plate and the bottom end of the second longitudinal plate. The first longitudinal plate has multiple mounting holes along its length, and the sliding groove is fixedly installed on the inner bottom of the door panel by means of screw locking parts engaging with the mounting holes. The long slot is located on the transverse plate.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a stepped bolt to achieve flexible swinging of the limiting rod. As the door panel gradually opens, the stepped bolt slides along the long slot, causing the second end of the limiting rod to swing. When the stepped bolt slides to the round hole, it falls a certain distance under gravity, allowing the stepped bolt to engage with the round hole to fix the limiting rod and the sliding groove, thus forming a positioning support. This fixes the opening angle between the door panel and the cabinet, preventing hard collisions between the door panel and the cabinet, avoiding noise and damage to the cabinet and door panel. The overall strength is high, and the positioning support has good stability. Attached Figure Description

[0026] See Figure 1-8As shown in the figure, as an embodiment of the present utility model, a door panel limiting device is provided for installation between the cabinet body and the door panel of a cabinet. The right side of the door panel is rotatably connected to the right side of the cabinet body via a hinge to realize opening and closing. There is one door panel limiting device, which is installed at the bottom end of the side near the hinge between the cabinet body and the door panel. The door panel limiting device includes a limiting rod 1 and a sliding groove 2. The first end of the limiting rod 1 is hinged to the cabinet body, and the second end is equipped with a stepped bolt 5. The sliding groove 2 is fixedly installed at the bottom end of the inner side of the door panel. The sliding groove 2 is provided with a long slot 3. One end of the long slot 3 is provided with a round hole 4. The diameter of the round hole 4 is larger than the width of the long slot 3. The stepped bolt 5 slides and engages with the long slot 3 to drive the limiting rod 1 to swing. The first end of the limiting rod 1 is the fixed end, and the second end is the swinging end. The stepped bolt 5 and the round hole 4 limit and engage to realize that the limiting rod 1 and the sliding groove 2 are relatively fixed to form a positioning support. This invention utilizes a stepped bolt 5 to achieve flexible swinging of the limiting rod 1. When the door panel gradually opens, the stepped bolt 5 slides in the direction of the long slot 3, thereby causing the second end of the limiting rod 1 to swing. When the stepped bolt 5 slides to the position of the round hole 4, under the action of gravity, the stepped bolt 5 falls a certain distance, allowing the stepped bolt 5 to engage with the round hole 4 to achieve relative fixation between the limiting rod 1 and the sliding groove 2, forming a positioning support. This fixes the opening angle between the door panel and the cabinet, preventing hard collisions between the door panel and the cabinet, thus avoiding noise and damage to the cabinet and door panel. Furthermore, the overall strength is high, and the positioning support has good stability. When it is necessary to close the door panel, the stepped bolt 5 is manually lifted and moved into the long slot 3. Then, the door panel is rotated to close, and the stepped bolt 5 slides away from the long slot 3, thereby causing the second end of the limiting rod 1 to swing back and reset, thus closing the door panel.

[0027] In this embodiment, the stepped bolt 5 includes a first cylinder 51, a second cylinder 52, a third cylinder 53, and a fourth cylinder 54, whose diameters gradually decrease from top to bottom. The second end of the limiting rod 1 has a screw hole 9. The surface of the fourth cylinder 54 has an external thread. The second end of the limiting rod 1 is located below the sliding groove 2. The fourth cylinder 54 passes through the elongated slot 3 from top to bottom and is threadedly connected to the screw hole 9 of the limiting rod 1, which facilitates installation, removal, and maintenance. The diameter of the first cylinder 51 is larger than the diameter of the circular hole 4. The bottom wall of the second cylinder 52 abuts against the top walls on both sides of the circular hole 4 to provide positioning and support. The diameter of the second cylinder 52 is smaller than the diameter of the circular hole 4. The diameter of the second cylinder 52 is larger than the width of the elongated slot 3. The bottom wall of the second cylinder 52 abuts against the top walls on both sides of the elongated slot 3 to provide sliding support. The diameters of the third cylinder 53 and the fourth cylinder 54 are smaller than the width of the elongated slot 3.

[0028] In this embodiment, the diameter of the bottom end of the second cylinder 52, the third cylinder 53, or the fourth cylinder 54 gradually decreases from top to bottom, which serves as a guide for the upper and lower parts, thereby making the stepped bolt 5 fall more smoothly when it is in the position of the long slot 3 or the round hole 4.

[0029] In this embodiment, an inverted U-shaped fixing member 6 is also included. The fixing member 6 is used to fix the limiting rod 1 to the cabinet. A through hole 9 is opened on the first end of the limiting rod 1 and the fixing member 6. A bolt passes through the through hole 9 and engages with a nut to hinge the first end of the limiting rod 1 to the fixing member 6, thereby improving the assembly and operational stability of the limiting rod 1. The top of the stepped bolt 5 has a slotted groove to facilitate the tightening or loosening of the stepped bolt 5 with a slotted screwdriver.

[0030] In this embodiment, the longitudinal section of the sliding groove 2 is U-shaped, including a first longitudinal plate 21, a second longitudinal plate 22, and a transverse plate 23 connecting the bottom end of the first longitudinal plate 21 and the bottom end of the second longitudinal plate 22. The first longitudinal plate 21 has a plurality of mounting holes 7 along its length. The sliding groove 2 is fixedly installed on the inner bottom of the door panel by locking the mounting holes 7 with screws. The long slot 3 is located on the transverse plate 23. This arrangement makes the sliding groove 2 stronger and the positioning support of the sliding groove 2 more stable.

[0031] Of course, in other cases, there can also be two round holes 4, located at the end and middle of the long slot 3 respectively. This allows the stepped bolt 5 to engage with the middle round hole 4 to achieve relative fixation between the limiting rod 1 and the sliding groove 2 when the door panel does not need to open to a large angle, thus improving work efficiency. Alternatively, there can be two door panel limiting devices, installed at the upper and lower ends near the hinge between the cabinet and the door panel.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
