Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses handcart parking equipment, as shown in fig. 1 and 2, includes: a loading board 1 for bearing article installs a plurality of gyro wheels in the bottom of loading board 1, simultaneously, installs the handle in one side of loading board 1, when article such as luggage need be transported, can put things in good order luggage on the loading face of loading board 1, promotes the handle and can drive whole loading board 1 and remove.

In practice, because the condition that the rolling aversion appears very easily in the gyro wheel of loading board 1 bottom, lead to loading board 1's stability relatively poor, therefore, in this embodiment, one side of keeping away from the handle in loading board 1's bottom is installed locating lever 2, locating lever 2 perpendicular to loading board 1 sets up, sliding sleeve is equipped with parking subassembly 3 on locating lever 2, and simultaneously, be provided with drive assembly 4 in loading board 1's bottom, when needs stop loading board 1's removal, drive assembly 4 can be utilized, drive parking subassembly 3 slides along the extending direction of locating lever 2, the bottom butt until parking subassembly 3 is subaerial, thereby realize the removal to loading board 1's support and restriction its position.

In the embodiment, the parking assembly 3 comprises a sleeve 31 which is sleeved on the positioning rod 2 in a sliding manner, reinforcing plates 32 are connected to two sides of the sleeve 31, a parking block 33 is connected to the bottom of the sleeve 31 in a threaded manner, it should be noted that the parking block 33 is integrally in a circular table shape, the cross section of the parking block is trapezoidal, the outer diameter of the parking block 33 is gradually increased towards one side far away from the positioning rod 2, when the parking block 33 is abutted to the ground, the contact area between the parking block and the ground can be increased, and therefore the stability of the whole parking assembly can be effectively improved.

In this embodiment, the driving assembly 4 includes: the tip articulates the first connecting rod 41 in the sleeve pipe 31 outside, in order to improve parking subassembly 3's bulk strength and smooth and easy degree, be connected with two reinforcing plates 32 in the outside of sleeve pipe 31, and the tip of first connecting rod 41 then articulates on reinforcing plate 32, the one end of keeping away from reinforcing plate 32 at first connecting rod 41 still articulates there is first connecting plate 42, the one end that first connecting plate 42 kept away from first connecting rod 41 articulates on the bottom surface of loading board 1, it explains that, when first connecting rod 41 and first connecting plate 42 rotate to being in same rectilinear state, parking piece 33 just can the butt subaerial, thereby realize support and restriction to loading board 1.

Wherein, drive assembly 4 still includes the driving piece that sets up in loading board 1 bottom, and the first connecting plate 42 of drive that the driving piece can be very convenient drives first connecting rod 41 and carries out rotary motion, and in this embodiment, the driving piece includes: the tip articulates the second connecting plate 44 on loading board 1 bottom face, and it should be noted that, second connecting plate 44 all is in the coplanar with locating lever 2 and first connecting plate 42, that is to say, the mounting point of three and loading board 1 is located same straight line, and such setting can improve whole parking device's stability.

An operating rod 43 is rotatably connected to one end of the second connecting plate 44 far away from the bearing plate 1, the shaft of the operating rod 43 is hinged to the lower end of the second connecting plate 44, one end of the operating rod 43 close to the first connecting plate 42 is hinged to a secondary connecting rod 410, and one end of the secondary connecting rod 410 far away from the operating rod 43 is hinged to the first connecting rod 41.

When the bearing plate 1 needs to be parked, one end of the operating rod 43 far away from the first connecting plate 42 can be stepped by a foot, at this time, the operating rod 43 can drive the auxiliary connecting rod 410 to rotate, one end of the auxiliary connecting rod 410 far away from the first connecting rod 41 can rotate towards the direction close to the first connecting plate 42, in the rotating process, the auxiliary connecting rod 410 can drive the first connecting rod 41 and the first connecting plate 42 to move to the state of being in the same straight line, when the first connecting rod 41 and the first connecting plate 42 rotate to form a straight line, the end part of the first connecting rod 41 can drive the parking component 3 to slide on the positioning rod 2 until the parking block 33 at the bottom of the sleeve 31 is abutted against the ground, and therefore the limitation on the position of the bearing plate 1 is realized.

In order to further improve the stability of the whole parking device, an accommodating groove 420 matched with the auxiliary link 410 is arranged on one side of the first connecting plate 42 close to the operating rod 43, the extending direction of the accommodating groove 420 is consistent with the extending direction of the first connecting plate 42, when the operating rod 43 drives the auxiliary link 410 to rotate, when the first connecting rod 41 and the first connecting plate 42 are in the same straight line state, the auxiliary link 410 can be just accommodated in the accommodating groove 420 of the first connecting plate 42, so that the contact area between the first connecting plate 42 and the auxiliary link 410 can be increased, and the stability of the operating process can be improved.

In order to reduce the operating space and control the parking block 33 to move with a relatively small force, in this embodiment, one end of the sub link 410, which is far away from the first link 41, is provided as a bent portion 411 bent toward the operating lever 43, and the end of the operating lever 43 is hinged to the bent portion 411.

In addition, the extension rod 430 is inserted into one end of the operating rod 43 far away from the secondary link 410 in a sliding manner, and the extension direction of the extension rod 430 is consistent with the extension direction of the operating rod 43, so that the advantage is that the extension rod 430 can be retracted into the operating rod 43 when the extension rod 430 is not used, and the parking block 33 can be operated to move with little force when the parking block is used, thereby facilitating the operation.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
