[0004] However, subway waiting seats are only composed of seat legs and seat boards, and can only be used for waiting personnel to sit and rest. When waiting personnel eat, they can only place food on their legs or hold it with their hands, which is extremely inconvenient. When there are too many personal belongings, they can only place the items on the ground, affecting the passage of people. Currently, waiting seats cannot provide convenient use, thereby reducing the utilization rate of waiting seats. Utility Model Content

DETAILED DESCRIPTION

[0027] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] The technical solution in the embodiments of the present application effectively solves the technical problem that the subway waiting seats are only composed of seat legs and seat boards and can only be used for waiting personnel to sit and rest. When the waiting personnel are eating or have too many personal belongings, the current waiting seats cannot provide convenient use, thereby reducing the utilization rate of the waiting seats.

[0029] The following is a detailed description of the utility model with reference to the accompanying drawings. The present embodiment discloses a subway waiting seat, such as Figure 1 As shown, it includes a seat body 21, a chair leg 24 is arranged at the lower part of the seat body 21, a fixed base 23 is arranged at the side of the chair leg 24, a guide rod 22 is fixedly installed at the upper part of the fixed base 23, a lifting frame 31 is sleeved on the guide rod 22, and a wedge block 33 is fixedly installed at the bottom of the inner wall of the lifting frame 31;

[0030] The upper end of the guide rod 22 is fixedly installed with the fixed block 11; the upper end of the fixed block 11 is provided with a second slide groove 13, and the second slide groove 13 penetrates the fixed block 11; the side of the fixed block 11 is provided with a first slide groove 12, and the first slide groove 12 is connected with the second slide groove 13; a pressing plate 14 is provided in the first slide groove 12, and a rectangular through hole 15 is provided on the pressing plate 14.

[0031] The guide rods 22 are symmetrically arranged at both ends of the wedge block 33, and square openings are arranged at both ends of the bottom of the lifting frame 31. The guide rods 22 pass through the square openings at the bottom of the lifting frame 31. A card slot is arranged on the side of the wedge block 33. The lifting frame 31 is a U-shaped structure, and a placement plate 32 is arranged on the upper part of the lifting frame 31. The placement plate 32 is located on the upper part of the seat body 21. The wedge block 33 is slidably installed in the second slide groove 13 opened in the fixed block 11, wherein the card slot of the wedge block 33 is movably sleeved in the rectangular through hole 15 opened in the pressing plate 14.

[0032] A spring 16 is disposed on the side of the pressing plate 14, one end of the spring 16 is fixedly connected to the inner wall of the first slide groove 12, and the other end is fixedly connected to the pressing plate 14. Two springs 16 are disposed, and the two springs 16 are disposed at both ends of the side of the pressing plate 14. The spring 16 is in a free state when the placing plate 32 is not in use. When the placing plate 32 moves upward, the spring 16 is first squeezed by the wedge block 33. After the rectangular through hole 15 of the wedge block 33 is aligned with the pressing plate 14, the spring 16 returns to a free state, thereby limiting the position of the placing plate 32.

[0033] Four chair legs 24 are provided, and the fixed base 23 is fixedly connected to the two chair legs 24 on the left side. The chair legs 24 are provided at the four corners of the lower part of the seat body 21, which can provide stable support for the seat body 21 and ensure safety. The width of the wedge block 33 is smaller than the width of the rectangular through hole 15 on the pressing plate. The wedge block 33 rises together with the lifting frame 31, and the wedge block 33 passes through the rectangular through hole 15 on the pressing plate 14.

[0034] The four sides of the seat body 21 and the placement board 32 are all set to be arcuate structures. The arcuate structure can improve the safety of the seat body 21 and the placement board 32 when in use, and avoid stabbing or scratching the waiting passengers. The backrest 25 is set at the rear side of the seat body 21, and the waiting passengers can lean on the backrest 25 when sitting down. The backrest 25 is set obliquely, which can increase the comfort of the waiting seat.

[0035] Working principle: When the waiting chair is in use, the user can move the placing plate 32 toward the upper end of the seat body 21. During the upward movement of the placing plate 32, the lifting frame 31 is driven to move upward. At this time, the wedge block 33 at the bottom of the inner wall of the lifting frame 31 moves upward at the same time. When the wedge block 33 moves upward to a certain position, it will be aligned with the second slide groove 13 provided in the fixed block 11, and will pass through the second slide groove 13 provided in the fixed block 11. Through the bevel design of the wedge block 33, the wedge block 33 will squeeze the rectangular through hole 15 opened in the pressing plate 14. After being squeezed to a certain position, it will pass through the rectangular through hole 15 opened in the pressing plate 14. When the slot opened in the wedge block 33 is aligned with the rectangular through hole 15 opened in the pressing plate 14, the pressing plate 14 will be squeezed outward under the elastic force of the two springs 16. At this time, the pressing plate 14 will be connected with the slot opened in the wedge block 33 through the opened rectangular through hole 15, and the lower end of the wedge block 33 will be installed in the fixed block 11, and the placement plate 32 will also be higher than the upper end of the seat body 21.

[0036] The seat back is tilted backward, and there is a certain distance between the placement board 32 and the seat back, so after lifting, the placement board 32 is aligned with the front end of the seat body up and down, and the position between the placement board 32 and the seat back can be used for users to sit, thereby ensuring that the placement board 32 does not affect the user's sitting when it is raised, and the user can place items or eat on the placement board 32.

[0037] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
