DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5The utility model provides a technical solution: a waiting bench with an extendable structure, comprising a seat plate 1 and a limiting mechanism 8, an extending mechanism 3 is installed on the inner side of the seat plate 1, a telescopic frame 2 is installed below the extending mechanism 3, a supporting frame 4 is fixedly installed below the seat plate 1, connecting frames 5 are connected to both ends of the seat plate 1, an adjusting mechanism 6 is provided on the inner side of the connecting frame 5, a placing plate 10 is connected to the top of the adjusting mechanism 6, a No. 3 slide groove 9 is opened inside the seat plate 1 near the extending mechanism 3, the limiting mechanism 8 is arranged in the built-in groove of the seat plate 1 near the No. 3 slide groove 9, and one side of the limiting mechanism 8 is connected to the extending mechanism 3, and one end of the limiting mechanism 8 is connected to a turning handle 7.

[0028] according to Figure 1-3 and Figure 6 As shown, the extension mechanism 3 includes a slider 301, a storage groove 302, an extension plate 303, a movable groove 304 and a stopper 305. The inner side of the seat plate 1 is provided with a storage groove 302, and the interior of the storage groove 302 is slidably connected with an extension plate 303. The two ends of the extension plate 303 near the third slide groove 9 are connected with sliders 301, and the slider 301 is slidably connected to the third slide groove 9. The top of the extension plate 303 is connected with a stopper 305. The interior of the seat plate 1 near the stopper 305 is provided with a movable groove 304, and the stopper 305 and the movable groove 304 are slidably connected. The bottom end of the extension plate 303 is connected to the telescopic frame 2, and the number of the telescopic frames 2 is two.

[0029] During specific implementation, since the seating area of ​​the waiting bench is generally fixed and it is not convenient for multiple people to sit on it, the height of the telescopic frame 2 can be adjusted first to prevent the telescopic frame 2 from rubbing against the ground when the extension plate 303 is pulled, and then the extension plate 303 can be pulled to one side so that the extension plate 303 drives the slider 301 to slide to one end in the third slide groove 9, and at the same time drives the stopper 305 to slide in the movable groove 304, so that the extension plate 303 can be pulled out quickly, and then the height of the telescopic frame 2 can be adjusted so that the bottom end of the telescopic frame 2 is in contact with the ground to support the extension plate 303, so that multiple people can sit on the waiting bench, thereby improving the convenience of the waiting bench.

[0030] according to Figure 1 , Figure 2 and Figure 4As shown, the adjustment mechanism 6 includes a No. 1 slide groove 601, a knob 602, a No. 1 screw 603 and an adjustment rod 604. A No. 1 slide groove 601 is provided on the inner wall of the connecting frame 5. An adjustment rod 604 is slidably connected to one side of the No. 1 slide groove 601. A No. 1 screw 603 is installed inside the connecting frame 5 near the adjustment rod 604 through a bearing. The No. 1 screw 603 and the adjustment rod 604 are threadedly connected. One end of the No. 1 screw 603 is connected to the knob 602. The top of the adjustment rod 604 is connected to the placement plate 10, and a placement groove is provided on the inner side of the placement plate 10.

[0031] During specific implementation, since armrests are usually set on both sides of the waiting bench, but the height of the armrests cannot be adjusted according to the passengers' usage needs, the comfort of the waiting bench is reduced. The knob 602 can be rotated to drive the No. 1 screw 603, and then the adjustment rod 604 moves up or down on the outside of the No. 1 screw 603. At the same time, the two ends of the adjustment rod 604 slide up and down in the No. 1 slide groove 601, so that the adjustment rod 604 drives the height of the placement plate 10 to change, which can meet the usage needs of different passengers and improve the comfort of the waiting bench.

[0032] according to Figure 1-3 and Figure 5-7 As shown, the limiting mechanism 8 includes a No. 2 screw 801, a No. 2 slide groove 802, a No. 1 gear 803, a No. 2 gear 804, a limiting groove 805 and a limiting block 806. The No. 2 screw 801 is installed in the built-in groove of the seat plate 1 close to the No. 3 slide groove 9 through a bearing, and the outer side of the No. 2 screw 801 is threadedly sleeved with a limiting block 806. The No. 2 slide groove 802 is provided in the built-in groove of the seat plate 1 close to the limiting block 806, and the No. 2 slide groove 802 and the limiting block 806 are slidably connected. The outer side of the No. 2 screw 801 is fixedly sleeved with a No. 1 gear 803, and one side of the No. 1 gear 803 is meshed with the No. 2 gear 804. A limiting groove 805 is provided on the side of the slider 301 close to the limiting block 806. One end of the No. 2 gear 804 is connected to the handle 7 through a transmission shaft, and the cross-sectional shape of the limiting block 806 is "L"-shaped.

[0033] In specific implementation, after the extension plate 303 is pulled to the limited position, the handle 7 is rotated to make the handle 7 drive the second gear 804 to rotate, and the second gear 804 drives the first gear 803 to rotate, and the first gear 803 drives the second screw 801 to rotate, and then the limit block 806 moves downward on the second screw 801, and at the same time, the two ends of the limit block 806 slide downward in the second slide groove 802, so that the limit block 806 is stuck in the limit groove 805 of the slider 301, limiting the position of the slider 301, and then limiting the position of the extension plate 303, thereby improving the stability of the waiting bench.

[0034] Working principle: When using this waiting bench with an extendable structure, first, passengers can sit on the seat board 1 and wait for the subway. When there are many passengers, the extension board 303 can be pulled out through the extension mechanism 3, and the position of the extension board 303 can be limited by the limiting mechanism 8 at the same time, so as to quickly adjust the sitting area of ​​the waiting bench. Water cups and items can be placed on the placement board 10, which can also be used as an armrest. The height of the armrests on both sides for placing items can be adjusted according to the needs of use. The height of the placement board 10 can be adjusted by the adjustment mechanism 6, which improves the convenience and comfort of the waiting bench. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
