Description

Technical Field

[0001] The utility model belongs to the technical field of equipment boxes, and in particular relates to a convenient equipment box for a seat. Background Art

[0002] As subway functions become more and more comprehensive, the number of electrical components inside the subway is bound to increase. However, conventional electrical cabinets are distributed in the four corners of the car, and the space is limited. In order not to reduce the comfort of subway passengers, the volume of the electrical cabinets in the four corners of the conventional car cannot be increased. Therefore, electrical components that cannot be arranged (such as the main unit) are placed under the seats. Three main units can be placed under a conventional six-seat long row of seats using a conventional under-seat equipment box with a drag chain on one side and the main unit on the other side. However, sometimes there will be special five-seat long rows of seats. In this case, if three more main units are placed, the conventional under-seat equipment box with a drag chain on one side and the main unit on the other side cannot be used. The equipment box needs to be reduced in width. Therefore, a convenient equipment box for seats is needed.

[0003] As the overall internal width of the existing seat equipment box is reduced, it is not convenient to place more host equipment in the limited space under the seat, which reduces the space utilization under the seat. When there are too many wiring harnesses, it is not convenient to electrically connect the subway vehicle wiring harness with the host equipment, which greatly reduces the practicality. Utility Model Content

[0004] The utility model provides a convenient equipment box for seats, which aims to solve the problem that the existing equipment box for seats is not convenient for placing more host devices in the limited space under the seat when the overall internal width space under the seat is reduced, thereby reducing the space utilization under the seat; when there are too many wiring harnesses, it is inconvenient to electrically connect the subway vehicle wiring harness with the host device, thereby greatly reducing the practicality.

[0005] An embodiment of the present utility model provides a convenient equipment box for a seat, comprising a mounting seat, to which a bottom frame is fixedly connected, a drag chain is provided at the upper end of the bottom frame, and a slide rail is fixedly connected at one end of the bottom frame away from the mounting seat.

[0006] Furthermore, a reinforcing plate 1 is fixedly connected to the mounting seat.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Reference Figure 1-4 The embodiment of the present invention provides a convenient equipment box for a seat, including a mounting base 1, to which a reinforcing plate 2 is fixedly connected, thereby improving the firmness of the mounting base 1.

[0029] The mounting seat 1 is fixedly connected to a bottom frame 3, a reinforcing rib 13 is fixedly connected to the bottom wall of the bottom frame 3, the left and right side walls of the bottom frame 3 are respectively fixedly connected to reinforcing brackets 6, a fixing frame 4 is fixedly connected to the rear wall of the bottom frame 3, and a wire tie rod 7 is fixedly connected to the upper end of the fixing frame 4, which facilitates the installation of the drag chain 9 and improves the firmness of the bottom frame 3.

[0030] A drag chain 9 is provided at the upper end of the bottom frame 3, and a drag chain cross bar 17 is provided on the drag chain 9. One end of the drag chain 9 is fixedly connected to the side wall of the fixed frame 4, and the drag chain cross bar 17 is located on the inner radial side of the drag chain 9. The drag chain 9 is installed at the upper end of the main device 11, which is beneficial to greatly save the horizontal space under the seat. The drag chain 9 is installed in a flat manner, which is beneficial to save the vertical space under the seat. Two drag chains 9 are placed on both sides of the upper end of the main device 11, and the drag chain cross bar 17 in the inner radial direction of the drag chain 9 can be opened to facilitate more wiring harnesses to enter the main device 11 through the drag chain 9. The setting of the drag chain 9 is beneficial to prevent the wiring harness from being damaged during movement.

[0031] The end of the bottom frame 3 away from the mounting seat 1 is fixedly connected to the slide rail 10, and the end of the slide rail 10 away from the bottom frame 3 is fixedly connected to the sliding tray 12. The side wall of the sliding tray 12 is fixedly connected with a reinforcing plate 2 15, a reinforcing beam 14 and a mounting frame 16. The front end wall of the mounting frame 16 is fixedly connected with a wire tie rod 2 8. The upper ends of the reinforcing beam 14 and the mounting frame 16 are fixedly connected with a fixing frame 2 5. The main device 11 is placed on the inner side of the sliding tray 12. The setting of the slide rail 10 facilitates the smooth sliding out of the sliding tray 12, and the sliding out stroke exceeds the depth of the main device 11, which is conducive to making the main device 11 completely slide out of the space under the seat, making it convenient for maintenance personnel to inspect it.

[0032] The other end of the drag chain 9 is fixedly connected to the side wall of the fixed frame 2 5, and the drag chain cross bar 17 is located on the inner radial side of the drag chain 9. The drag chain 9 is installed at the upper end of the main device 11, which is beneficial to greatly save the horizontal space under the seat. The drag chain 9 is installed in a flat position, which is beneficial to save the vertical space under the seat. Two drag chains 9 are placed on both sides of the upper end of the main device 11, and the drag chain cross bar 17 in the inner radial direction of the drag chain 9 can be opened to facilitate more wiring harnesses to enter the main device 11 through the drag chain 9. The setting of the drag chain 9 is beneficial to prevent the wiring harness from being damaged during movement.

[0033] The specific implementation method is as follows: when in use, first place the entire equipment box in the space under the seat, fix the mounting base 1 on the floor under the subway seat, enter the subway vehicle wiring harness from one end of the two drag chains 9, pass through the other end of the drag chain 9 and electrically connect it to the host device 11. When there are too many wiring harnesses, open the drag chain cross bar 17, lay the wiring harness directly in the drag chain 9, retract the slide rail 10 to move the sliding tray 12 and the host device 11 to the inside of the bottom frame 3, so that the entire equipment box is placed in the space under the seat. When maintenance or debugging is required, the maintenance personnel slowly drag the host device 11 and the sliding tray 12 out to the space outside the seat through the slide rail 10. At the same time, the wiring harness will also be slowly dragged out toward the host device 11 along the drag chain 9, so that the entire equipment box is exposed to the space where the maintenance personnel can operate and repair it, so as to facilitate maintenance and debugging.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
