Description

Technical Field

[0001] This utility model belongs to the field of subway equipment technology, specifically relating to a secondary anti-detachment device for the door panel of a subway battery box. Background Technology

[0002] The subway battery box is a device suspended at the bottom of the subway car. It is very important to prevent the door panel of the battery box from falling off. Currently, most subway battery box door panels do not have a secondary anti-fall device, which will shake during the operation of the vehicle and may even fall off. Currently, most subway battery box door panels have a slight tilt after the secondary anti-loosening latch is placed in a horizontal position, making it difficult to open and close the door. Utility Model Content

[0003] The purpose of this utility model is to provide a secondary anti-detachment device for the door panel of a subway battery box, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a secondary anti-detachment device for a subway battery box door panel, comprising a lock seat and a lock plate, wherein a spring groove is formed in the lock seat, a spring is provided in the spring groove, a ball is provided on one side of the spring, a lock tongue is connected to one side of the lock seat, a cylindrical groove adapted to the ball is provided on the lock tongue, and an opening is provided on the lock plate, through which the lock tongue passes.

[0005] Preferably, the cylindrical groove is located in the middle and bottom of the latch.

[0006] Preferably, a rotating rod is provided at one end of the lock seat, and the rotating rod passes through the lock tongue.

[0007] Preferably, the latch has a waist-shaped hole, and the rotating rod passes through the waist-shaped hole.

[0008] The technical effects and advantages of this utility model are as follows: when the latch is always in a vertical position, the latch is locked on one side of the lock plate, which plays a secondary role in preventing the door panel from falling off. When the latch is adjusted to the horizontal position, the latch can be kept completely horizontal by using a ball to lock in the cylindrical groove at the bottom of the latch, preventing it from tilting and making it easier to open and close the door.

[0010] In the diagram: 1. Lock seat; 2. Spring groove; 3. Spring; 4. Ball; 5. Lock tongue; 6. Rotary rod; 7. Waist-shaped hole; 8. Cylindrical groove; 9. Lock plate. Detailed Implementation

[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0012] This utility model provides, for example Figure 1-4 The illustrated secondary anti-detachment device for a subway battery box door panel includes a lock base 1 and a lock plate 9. The lock base 1 has a spring groove 2, and a spring 3 is installed within the spring groove 2. A ball 4 is positioned on one side of the spring 3. A latch 5 is connected to one side of the lock base 1. The lock plate 9 has an opening through which the latch 5 passes, and the lock plate 9 is installed on the door panel. A rotating rod 6 is located at one end of the lock base 1, passing through the latch 5. The latch 5 has a cylindrical groove 8 that matches the ball 4. The cylindrical groove 8 is located in the middle and bottom of the latch 5. During subway operation, the latch 5 remains vertical (perpendicular to the lock base 1), and is engaged with one side of the lock plate 9, effectively providing secondary anti-detachment protection for the door panel. When the door panel needs to be removed, the latch is rotated to a horizontal position (the latch 5 is parallel to the lock base 1). The ball 4 engages with the cylindrical groove 8 at the bottom of the latch 5, maintaining a completely horizontal position for easy opening and closing of the door panel.

[0013] Specifically, the latch 5 has a waist-shaped hole 7, and the rotating rod 6 passes through the waist-shaped hole 7, which allows for easy rotation of the latch 5 and convenient adjustment of the latch 5's state.

[0014] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
