Description

Technical Field

[0001] This utility model relates to the field of cabinet door limiting structures, and in particular to a door opening limiting mechanism. Background Technology

[0002] When workers are wiring or repairing circuits, the cabinet doors of control cabinets, distribution cabinets, or other electrical cabinets are in a state of free movement, which affects their operation. In windy weather, the doors may also blow into workers, resulting in low safety. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the background technology by proposing a door opening limit mechanism that can limit the opening of the cabinet door to a certain angle, prevent it from affecting the worker's operation, and reduce the risk of the cabinet door hitting the worker due to strong winds, thereby improving safety.

[0004] The technical solution of this utility model is a door opening limit mechanism, including a pull rod and a rotating seat; one end of the pull rod has a rotating part, and the other end is provided with a limit member; the rotating seat has a slide and a number of locking channels that can be locked into the limit member, the slide and the number of locking channels are distributed in sequence, and the slide and adjacent locking channels, as well as two adjacent locking channels, are connected by a connecting channel, the width of the connecting channel being smaller than the width of the slide and the width of the locking channel.

[0005] Preferably, the rotary table is made of ABS material.

[0006] Preferably, the end of the rotary seat has a notch that communicates with the outermost track.

[0007] Preferably, the opening at the end of the card track facing the slide has a guide slope.

[0008] Preferably, the limiting element is a bolt.

[0009] Preferably, the rotary table is provided with a bracket, and the bracket is provided with mounting holes.

[0010] Preferably, the bottom of the rotating base has a slot one, the top of the bracket has a slot two, and a baffle is fixedly connected to the bracket at slot two, with the baffle being engaged in slot one.

[0011] Compared with existing technologies, this utility model has the following beneficial technical effects: This utility model can limit the opening of the cabinet door to a certain angle, preventing it from affecting worker operations and reducing the risk of the cabinet door hitting workers in strong winds, thus improving safety. When the cabinet door is fully closed, the pull rod and the rotating seat are in a retracted state, and the bolt is located at the outer end of the slide rail. When the cabinet door is opened, the rotating seat uses the bolt to restrain it within the track, providing a certain degree of restriction. At this time, in windy weather, it is not easy for the wind to blow the cabinet door shut. Attached Figure Description

[0018] Example 1

[0019] like Figures 1-5 As shown in the figure, the door opening limit mechanism proposed in this embodiment includes a pull rod 1 and a rotating seat 3.

[0020] One end of the pull rod 1 has a rotating part, and the other end is provided with a limiting component. The limiting component is a bolt 2, or it can be a cylindrical structure, as long as it can move on the rotating base 3 and be limited to a certain extent.

[0021] The rotary seat 3 has a slide rail 301 and several locking channels 302 that can engage with limiting members. The slide rail 301 and the locking channels 302 are distributed sequentially. The slide rail 301 and adjacent locking channels 302, as well as two adjacent locking channels 302, are connected by connecting channels. The width of the connecting channels is smaller than the width of the slide rail 301 and the width of the locking channels 302. When the limiting member is a bolt 2 or a cylindrical structure, the diameter of the limiting member is larger than the width of the connecting channels. The rotary seat 3 is made of ABS material so that when the limiting member moves between the slide rail 301 and the locking channels 302, it can deform the rotary seat 3 through the connecting channels and be limited to a certain extent when it moves to the locking channel 302.

[0022] like Figures 1-5As shown, three guide rails 302 are arranged side by side and are aligned with the slide rails 301. When the limiting member engages with the outermost guide rail 302, the cabinet door opens to approximately 120°; when the limiting member engages with the middle guide rail 302, the cabinet door opens to approximately 105°; and when the limiting member engages with the innermost guide rail 302, the cabinet door opens to approximately 90°. However, this does not mean that the cabinet door can only open to these three angles; the specific angle needs to be determined based on actual requirements, and then the number and position of the guide rails 302 will be adjusted accordingly.

[0023] Furthermore, the end opening of the guide rail 302 facing the slide rail 301 has a guide slope, which guides the movement of the bolt 2 when the limiting member moves to the outer end of the slide rail 301.

[0024] This embodiment can limit the opening of the cabinet door to a certain angle, preventing it from affecting worker operations and reducing the risk of the cabinet door hitting workers in strong winds, thus improving safety. One end of the pull rod 1 is rotatably mounted on the frame at the bottom inside the cabinet via a rotating part, and the rotating seat 3 is mounted on the frame at the bottom inside the cabinet door. When the cabinet door is fully closed, the pull rod 1 and the rotating seat 3 are in a retracted state, and the bolt 2 is located at the outer end of the slide rail 301. When the cabinet door is opened, the cabinet door drives the rotating seat 3 to rotate outward, and the rotating seat 3 drives the pull rod 1 to rotate. The bolt 2 moves along the slide rail 301. When the bolt 2 passes through the connecting channel, it pushes and deforms the rotating seat 3. When the bolt 2 moves from the connecting channel to the locking channel 302, it no longer deforms the rotating seat 3, and the rotating seat 3 elastically contracts, restricting the bolt 2 within the locking channel 302, thus providing a certain degree of restriction. At this time, in windy weather, it is not easy for the wind to blow the cabinet door shut. When the cabinet door needs to be closed, the worker needs to push the cabinet door inward to make the bolt 2 pass through the connecting channel and finally move into the outer end of the slide 301, so that the limiting mechanism is in the retracted state.

[0025] Example 2

[0026] like Figures 1-5 As shown in the figure, the door opening limiting mechanism proposed in this embodiment has a notch 303 at the end of the rotating seat 3 that communicates with the outermost blocking channel 302, compared to the first embodiment. When the limiting member moves to the connecting channel, it is easier to push and deform the rotating seat 3 with the notch 303, avoiding the need for the user to use a lot of force to open and close the door.

[0027] Example 3

[0028] like Figures 1-5As shown in the figure, the door opening limiting mechanism proposed in this embodiment differs from that in Embodiment 1. In this embodiment, the rotating base 3 is provided with a bracket 4, and the bracket 4 is provided with a connecting hole 401. The rotating base 3 has corresponding screw holes, and the rotating base 3 and the bracket 4 can be connected by screws at the screw holes and the connecting hole 401. The bracket 4 is provided with mounting holes 402, through which the bracket 4 is installed on the cabinet door.

[0029] The bottom of the rotating base 3 has a slot 304, and the top of the bracket 4 has a slot 403. A baffle 5 is fixedly connected to the bracket 4 at slot 403, for example, by welding. The baffle 5 is engaged in slot 304. The top of the baffle 5 has an extension plate that can block the bottom frame of the cabinet door, and the bottom of the baffle 5 has an inner extension plate that can block the bottom of the rotating base 3. The fixed baffle 5 is used to reinforce and limit the rotating base 3, thereby improving the installation reliability of the rotating base 3.

[0030] In this embodiment, the rotating seat 3 is installed on the cabinet door by the bracket 4 and the baffle 5. When the cabinet door is opened and closed, the rotating seat 3 is driven to rotate by the bracket 4 and the baffle 5, thereby guiding the limiting component to the card channel 302 and limiting the rotation of the cabinet door to a certain extent.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
