Description

Technical Field

[0001] The utility model belongs to the technical field of interior decoration of rail trains, and particularly relates to a pull-out cabinet under a seat. Background Art

[0002] The cabinet under the seat in a rail train is a facility for installing a main unit. The existing solution consists of a frame, a supporting beam for installing the main unit, and left and right main unit installation brackets. The fronts of the left and right main unit installation brackets are in the same plane, and the main unit installation points are fixed thereon. The bottom of the main unit is placed on the supporting beam for installing the main unit to achieve the purpose of fixing the main unit.

[0003] In the prior art, the main unit installation interface is fixed. Once the main unit model changes, when replacing the main unit, the entire cabinet under the seat needs to be replaced, which is time-consuming and laborious. In addition, when maintaining the wiring of the main unit in the cabinet under the seat, the operator needs to lie on the vehicle floor and reach deep under the seat for maintenance. The vision is poor, the operation space is small, and the operation is inconvenient.

[0004] Therefore, there is an urgent need for a new technical solution in the prior art to solve this problem. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a pull-out cabinet under a seat, which is used to solve the problems of small operation space and inconvenient operation.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a pull-out cabinet under a seat, including a cabinet frame under the seat and a main unit tray; the cabinet frame under the seat is fixedly installed on the floor under the seat, and sliding rails are arranged at both ends inside the cabinet frame under the seat, and a support column is also arranged at one end of the cabinet frame under the seat; the main unit tray is of a U-shaped frame structure, and the side walls of the main unit tray are slidably connected to the cabinet frame under the seat through the sliding rails; a cross beam is horizontally arranged at the top end of the support column; a drag chain is arranged on the cross beam; one end of the drag chain is fixed on the cross beam, and the other end of the drag chain is fixed on the side wall of the main unit tray.

[0007] Preferably, a wire tying rod and a grounding post are also arranged on the cross beam.

[0008] Preferably, the main unit wires are received in the drag chain.

[0009] Preferably, the connection between the main unit tray and the sliding rail is detachable.

[0010] Preferably, the sliding rail is a lockable sliding rail.

[0011] Through the above design scheme, the utility model can bring the following beneficial effects:

[0012] 1. The main unit can be pulled out from under the seat, providing sufficient operating space and a wide field of vision during maintenance, meeting the requirements of customers for the operability and visibility during the maintenance of the main unit.

[0013] 2. The main unit tray is an independent component, facilitating the replacement of the main unit. There is no need to replace the entire cabinet under the seat, and only the corresponding tray needs to be replaced.

[0014] 3. The slide rail can be locked when pushed back or pulled out, increasing stability. Description of the Drawings

[0015] Figure 1 FIG. is a schematic diagram of the pulled-out state of a pull-out type cabinet under the seat of the present utility model.

[0016] Figure 2 FIG. is a schematic diagram of the closed state of a pull-out type cabinet under the seat of the present utility model.

[0017] In the figure, 1 is the frame of the cabinet under the seat, 2 is the main unit tray, 3 is the slide rail, 4 is the support column, 5 is the cross beam, 6 is the drag chain, 7 is the wire tying rod, and 8 is the grounding post. Detailed Embodiment

[0018] The following is a detailed description of the specific embodiments of the present utility model with reference to the drawings.

[0019] It should be particularly noted that the terms "front and back, up and down, left and right" described in the text are only simplified expressions for intuitively describing the positional relationship based on the drawings, and are not limitations on the technical solution.

[0020] To more clearly illustrate the present invention, the following is a further description of the present invention with reference to the preferred embodiments. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive. Without departing from the inventive concept and scope set forth in the claims, users can make various changes to the following parameters. To avoid confusing the essence of the present invention, well-known methods and processes are not described in detail.

[0021] As shown in the attached Figures 1 to 2 : A pull-out type cabinet under the seat includes a frame 1 of the cabinet under the seat and a main unit tray 2; the frame 1 of the cabinet under the seat is fixedly installed on the floor under the seat, and slide rails 3 are provided at both ends inside the frame 1 of the cabinet under the seat, and a support column 4 is also provided at one end of the frame 1 of the cabinet under the seat; the main unit tray 2 is of a U-shaped frame structure, and the side walls of the main unit tray 2 are slidably connected to the frame 1 of the cabinet under the seat through the slide rails 3; a cross beam 5 is horizontally provided at the top end of the support column 4; a drag chain 6 is provided on the cross beam 5; one end of the drag chain 6 is fixed on the cross beam 5, and the other end of the drag chain 6 is fixed on the side wall of the main unit tray 2.

[0022] Furthermore, a wire tying rod 7 and a grounding post 8 are also provided on the cross beam 5. The wire tying rod 7 is used for routing wires, and the grounding post 8 is used for grounding the entire device.

[0023] Furthermore, the host wire is housed in the drag chain 6. The drag chain 6 not only plays a role in dragging but also in housing, killing two birds with one stone.

[0024] Furthermore, the host tray 2 and the slide rail 3 are detachably connected. It is convenient to replace the host without replacing the entire cabinet under the seat, and only the corresponding tray needs to be replaced.

[0025] Furthermore, the slide rail 3 is a lockable slide rail. It is convenient to lock the slide rail when pushing it back and pulling it out, increasing stability.

[0026] In a specific implementation, the slide rail 3 is connected to the frame 1 of the cabinet under the seat, the host tray 2 is connected to the slide rail 3, the host is installed on the host tray 2, the host wire is fixed in the side drag chain 6, and when the host tray 2 is pulled out, the host is pulled out from under the seat, facilitating maintenance. The cross beam 5 on the drag chain 6 above the frame of the cabinet under the seat is also welded with stiffeners to improve strength.

[0027] When maintaining the host and related wiring, the pull-out type cabinet under the seat pulls out the host. With this pull-out solution, the operator does not need to lie on the vehicle floor to observe. By reaching under the seat and pulling out the tray, the host can be pulled out from under the seat for maintenance, meeting the requirements of some owners for the operability and visibility during host maintenance.

[0028] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
