Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a medical small cart capable of freely going up and down stairs comprises a cart body 1, wherein a connecting seat 2 is fixedly arranged on the bottom end face of the cart body 1, a pulley 3 is rotatably arranged in the middle of the connecting seat 2, four connecting seats 2 are uniformly distributed on the bottom end face of the cart body 1, a fixed seat 5 is fixedly arranged at a position, which is lower than the middle of the foremost end of the cart body 1, the upper end face of the fixed seat 5 is threaded and provided with a threaded rod I6 in a penetrating manner, the bottom end of the threaded rod I6 is in threaded connection with the upper end face of a bottom plate 7, an electric push rod 4 is fixedly arranged in the middle of the rear end face of the cart body 1, the electric push rod 4 is placed in an inverted manner, the top end of the telescopic rod of the electric push rod 4 is rotatably connected with the upper end face of the bottom plate 7, the bottom plate 7 is shocking-shaped, and the bottom plate 7 is provided with a groove 13 in a penetrating manner, bottom plate 7 has threaded rod II 11 at the intermediate position department threaded connection of left side terminal surface and right side terminal surface, the inner wall of recess 13 slides through the spout and is provided with slider 15, slider 15 and expansion plate 16 fixed connection, the up end of expansion plate 16 and the up end of bottom plate 7 are in the coplanar, the bottom face of recess 13 and the one end fixed connection of spring 14, the other end of spring 14 and the medial surface fixed connection of expansion plate 16, lantern ring 10 has been cup jointed in the rotation of the outside of threaded rod II 11, and fixed cover in the top department of threaded rod II 11 has connect carousel 8, carousel 8 is fixed in the position department of deviating the centre of a circle and is provided with hand crank 9, the left surface and the right flank of lantern ring 10 all with the one end fixed connection of connecting rod 12, the other end of connecting rod 12 rotates through pivot 17 and expansion plate 16 to be connected.

The working principle is as follows: when the small handcart is used and meets stairs, firstly, the small handcart is stopped stably, then the threaded rod I6 is rotated to separate the threaded rod I6 from the bottom plate 7, then the electric push rod 4 is started, the telescopic rod of the electric push rod 4 pushes the bottom plate 7 downwards, when the bottom plate 7 is about to contact the bottom surface, the handle of the handcart body 1 is grasped, the rear end of the small handcart is lifted, the bottom plate 7 is continuously descended until the bottom plate is descended to a preset position, because the telescopic rod of the electric push rod 4 is rotatably connected with the bottom plate 7, after the bottom plate 7 moves to the preset position, the rear end of the handcart body 1 is slightly lifted under the support of the bottom plate 7, then the small handcart is rotated to rotate the threaded rod II 11 on the bottom plate 7, and at the moment, the small handcart is slightly inclined by a certain angle, the hand crank 9 on the rotary disc 8 is rotated by hands, let threaded rod II 11 outwards stretch, threaded rod II 11 rotates lantern ring 10 that cup joints under the restriction of connecting rod 12, can not take place to rotate, and connecting rod 12 pulls out expansion plate 16 from the recess 13 of bottom plate 7 under the pulling of lantern ring 10, reuse the hand shaking ware 9 of same method going to rotate the opposite side, just so can place the pulley 3 of dolly on expansion plate 16, we place the dolly and just can steadily slide on stair at whole bottom plate 7 and expansion plate 16, because bottom plate 7 can contact with a plurality of ladders simultaneously, play the shop and support, just can be comparatively easy pulling the dolly. The bottom plate 7 and the expansion plate 16 that can freely and conveniently receive and release are utilized, not only can let the dolly steady slip on the ladder, but also can be suitable reduce occupation space, let the user more laborsaving save time transport goods on stair, and install simple structure with low costs, above is exactly this utility model's theory of operation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
