Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, a transportation cart with a retractable size includes a bearing plate 1 and two hidden movable plates 2 for forming a larger bearing space with the bearing plate 1. Four corner positions in bottom of bearing plate 1 all are equipped with gyro wheel 3, and gyro wheel 3 has made things convenient for having the universal wheel of service brake, the setting of gyro wheel 3 the utility model discloses a remove when needs remove the utility model discloses the time, open the service brake, when need not to remove the utility model discloses the time, close the service brake. Hidden fly leaf 2 passes through connecting block 4 and special-shaped rail 5 sliding connection in the bottom of bearing plate 1. Two special-shaped rails 5 are symmetrically arranged on two sides of the lower portion of the bearing plate 1, a sliding rail is arranged on the special-shaped rails 5, the sliding rail comprises a linear groove 6, a first barb groove 7 and a second barb groove 8, the linear groove 6 is located on the lower edge of the special-shaped rails 5, the first barb groove 7 is obliquely arranged above the middle portion of the linear groove 6, the second barb groove 8 is obliquely arranged above the tail end of the linear groove 6, the first barb groove 7 and the second barb groove 8 both comprise an ascending section 9 communicated with the linear groove 6 and a barb groove 10 communicated with the ascending section 9, a connecting rod 11 is connected between two connecting blocks 4 on the same side, the two connecting blocks 4 on the same hidden movable plate 2 are more stably connected with the special-shaped rails 5, and the connecting blocks 4 are prevented from falling off the special-shaped rails 5. All be provided with two sliders that are used for inserting the slide rail and slide in the slide rail on the connecting block 4, the distance between two sliders equals the distance between first barb groove 7 and the second barb groove 8.

In addition, a limit block 13 is arranged at the tail end of the linear groove 6. The one end that connecting block 4 is close to stopper 13 is provided with push type spring catch 14, is provided with on the stopper 13 with the connector 15 that is connected with push type spring catch 14 cooperation, and push type spring catch 14 and rather than the connector 15 that the cooperation is connected are ripe prior art, need not to carry out detailed description here, can adopt three mai brand 075 model rebounders in this embodiment. The setting of stopper 13 can play limiting displacement to connecting block 4, prevents that connecting block 4 and special-shaped rail 5 from breaking away from, promotes the stability of connecting block 4. When the hidden movable plate 2 is pushed back to the bottom of the bearing plate 1, the connecting block 4 touches the limiting block 13, and the pressing type spring lock 14 is connected with the connecting head 15 in a matching manner, so that the connecting block 4 is locked on the limiting block 13, and the purpose of fixing the hidden movable plate 2 at the bottom of the bearing plate 1 is achieved. When the hidden movable plate 2 needs to be pulled out, the movable bearing plate 1 is pressed inward, and the pressing type spring fastener 14 is separated from the connector 15, and then the hidden movable plate 2 is pushed and pulled.

Two hand push rods 16 are symmetrically arranged at the top of the bearing plate 1, anti-skidding sleeves 12 are arranged on the hand push rods 16, and the anti-skidding sleeves 12 are made of silica gel materials. The setting of the handspike 16 facilitates the moving of the utility model, and the operator can push the handspike 16 by holding the utility model. The anti-slip sleeve 12 improves the comfort of the operator when holding the hand push rod 16, and can avoid the generation of static electricity.

The hidden movable plate 2 is provided with a handle 17 at the bottom edge. When the hidden movable plate 2 needs to be pushed and pulled, an operator can more conveniently push and pull the hidden movable plate 2 by holding the handle 17 with a hand, so that the using effect and the simplicity of conveniently pushing and pulling the hidden movable plate 2 are achieved.

The working principle is as follows: when the hidden movable plate 2 needs to be pulled out, only the movable bearing plate 1 needs to be pressed inwards, at this time, the press type spring lock 14 is separated from the connector 15, the hidden movable plate 2 is pushed and pulled, the handle 17 is held to pull the hidden movable plate 2 outwards, the two sliding blocks on the hidden movable plate 2 start to move along the linear groove 6, when one of the two sliding blocks moves to the tail end of the linear groove 6, the connecting block 4 cannot move any more, at this time, the two sliding blocks correspond to the positions of the first barb groove 7 and the second barb groove 8 respectively, the hidden movable plate 2 is also pulled out completely, the hidden movable plate 2 is lifted upwards, the sliding blocks slide along the rising section 9, and finally the sliding blocks fall into the barb groove 10. At this moment, the whole hidden movable plate 2 rises and is parallel to the bearing plate 1, and because the first barb groove 7 and the second barb groove 8 are inclined, under the action of the self gravity of the hidden movable plate 2, the sliding block cannot easily slide out of the first barb groove 7 and the second barb groove 8 and is matched with the barb groove 10 to achieve the function of locking the hidden movable plate 2. When the hidden movable plate 2 needs to be pushed back to the bottom of the bearing plate 1 again, the hidden movable plate 2 is lifted to separate the hidden movable plate 2 from the barb groove 10, then the hidden movable plate 2 is pressed downwards to move the slider down to the linear groove 6 along the ascending section 9, and finally the hidden movable plate 2 is pushed inwards to recover the hidden movable plate 2 to the bottom of the bearing plate 1 again, when the hidden movable plate 2 is pushed back to the bottom of the bearing plate 1, the connecting block 4 touches the limiting block 13, and the pressing type spring lock 14 is matched and connected with the connecting head 15 to lock the connecting block 4 on the limiting block 13, so that the purpose of fixing the hidden movable plate 2 to the bottom of the bearing plate 1 is achieved.
