Description

Technical Field

[0001] The invention relates to the technical field of nursing vehicles, and in particular to an auxiliary table plate which is easy to operate and a nursing vehicle composed of the auxiliary table plate. Background Art

[0002] Nursing carts are usually used to load medical machinery and medicines. If a nursing cart does not have an auxiliary table, its loading area may be relatively limited and cannot meet the needs of different patients. Especially in narrow aisles, a large nursing cart may be inconvenient to move, reducing the practicality of the nursing cart. Moreover, if a nursing cart does not have a foldable auxiliary table, it may take up more space when not in use, and the loading area cannot be quickly and conveniently expanded when needed.

[0003] At the same time, if the operator's one hand is occupied or needs to perform other tasks at the same time, how to quickly unfold or fold the auxiliary table with one hand.

[0004] Therefore, there is an urgent need for a foldable auxiliary table for a nursing vehicle that has a variable loading area, is easy to operate, and can be operated with one hand. Summary of the invention

[0005] Purpose of the invention: The purpose of the present invention is to address the shortcomings of the prior art that the loading area of ​​the nursing cart table is immutable or the auxiliary table requires two hands to operate, and to provide an easy-to-operate auxiliary table and a nursing cart composed of the auxiliary table, which can not only quickly expand the loading area of ​​the nursing cart table, but also realize the function of unfolding or folding the auxiliary table with one hand.

[0006] Technical solution: The auxiliary table with convenient operation described in the present invention comprises an auxiliary table, a folding device for driving the auxiliary table to unfold or close, and a locking device;

[0007] The folding device comprises an upper folding plate and a lower folding plate. The upper folding plate 4 and the lower folding plate 5 are hinged by a mounting shaft 9. The upper folding plate has two upper side plates, and an auxiliary table plate is fixed on the top of the upper folding plate. The lower folding plate is fixed on an external plane, and the lower folding plate has two lower side plates. When the upper folding plate and the lower folding plate are folded, the two lower side plates are located inside the two upper side plates, and the upper folding plate and the lower folding plate are locked or unlocked by a locking device.

[0008] The locking device includes two mounting holes on the upper side plate and two arc-shaped through holes on the lower side plate, and a pressing shaft passing through the mounting holes and the arc-shaped through holes on both sides from left to right;

[0009] When the locking device is in a locked state, the pressing shaft is fixed to the mounting hole and the arc-shaped through hole, so that the upper folding plate and the lower folding plate cannot flip relative to each other; when the locking device is in an unlocked state, the pressing shaft slides in the arc-shaped through hole, so that the upper folding plate and the lower folding plate flip relative to each other; when switching the locked state, only one hand is needed to operate the pressing shaft so that the pressing shaft slides out of the arc-shaped through hole, and when switching the unlocked state, only one hand is needed to operate the pressing shaft so that the pressing shaft falls into the arc-shaped through hole and slides.

[0010] Furthermore, the pressing shaft includes a main body tube, one end of which is connected to a sliding tube with a smaller diameter than the main body tube, a spring is sleeved on the outer circumference of the sliding tube, and the other end of the main body tube is connected to an unlocking tube with a smaller diameter than the main body tube; due to the action of the spring, when external force squeezes the unlocking tube, the sliding tube slides forward, at this time, the sliding tube and the unlocking tube fall into the arc-shaped through hole and slide, thereby driving the upper folding plate to expand or close.

[0011] Furthermore, a handle is provided on the unlocking tube in the outward direction; installing this handle can facilitate the operator to squeeze the pressing shaft, and because the handle has patterns, the friction can be increased, making it easier for the operator to operate.

[0012] Furthermore, one end of the spring close to the sliding tube is fixedly connected to the outer circumference of the sliding tube, and one end of the spring away from the sliding tube is sleeved on the outer circumference of the sliding tube; since the spring has elastic force, when the unlocking tube slides out of the arc-shaped through hole, the rebound force of the spring will drive the sliding tube to slide forward or backward.

[0013] The present invention further provides a nursing vehicle, comprising an auxiliary table, wherein a lower folding plate 5 of the auxiliary table is fixed on a main body of the nursing vehicle.

[0014] Beneficial effects: Compared with the prior art, the advantages of the present invention are:

[0015] (1) The utility model provides an auxiliary table that can be fixedly connected to the plane of any device through a folding device, thereby increasing the loading area of ​​the device. At the same time, due to the design of the folding device, the auxiliary table can be folded or unfolded, and the space utilization is flexible;

[0016] (2) The utility model provides a locking device. When the auxiliary plate needs to be folded, the handle can be pressed with one hand, so that the unlocking tube slides into the arc-shaped through hole, thereby driving the upper folding plate to move downward along the path of the arc-shaped through hole;

[0017] (3) The locking device of the present invention can quickly realize the unfolding and closing of the auxiliary table by one-hand operation through the coordinated work of the mounting hole, the arc-shaped through hole, the pressing shaft and some auxiliary parts.
