Description

Connection structure of shallow door plant

Technical Field

The utility model relates to the technical field of logistics and storage, in particular to a connection structure of a trolley door plate.

Background

Prior art carts include designs and uses of a push cart with doors or a pallet truck. Conventional door-equipped carts typically have a semi-or fully-enclosed door panel and a fixed connection post or deck structure. The door plates are fixed in the grooves on the surface of the lower layer plate and the bottom of the upper layer plate through the protruding parts on the upper side and the lower side of the door plates, so that the fixing and opening and closing functions of the door plates are realized. The installation of the cart usually adopts a connection mode of an aluminum pipe or a metal pipe and a plastic laminate, and the aluminum pipe or the metal pipe and the plastic laminate are matched and fixed by beating external force. Once the door panel is assembled, it is inconvenient to disassemble and multiple disassembles can affect the service life.

However, this conventional design has some problems. First, during installation, if the operation is not performed as required by the specification, a strong disassembly may be required, which easily results in damage to the fittings and reduces the firmness of the product. Secondly, traditional door plant structure is unfavorable for changing, once the door plant is damaged, and whole shallow service function is basically scrapped. In addition, the traditional design lacks flexibility to the demands of different working states, and the front door plate cannot be easily installed or detached.

Fig. 1 is a schematic structural diagram of a connection structure assembly of a door panel of a cart according to a preferred embodiment of the present application. In the embodiment shown in fig. 1 to 5, the connection structure of the cart door panel includes:

the laminate 1 has a first connection port 101 provided on the lower surface as a basis for connecting the door panels 2.

The upper end of the door plate 2 is embedded with the bottom of the laminate 1, and the lower end of the door plate 2 can also be embedded with the bottom of the laminate 1. The door panel 2 forms a first mounting box 20 and a first cover plate 21 covering the first mounting box 20 near the first connection port 101. The first mounting box 20 has a through hole corresponding to the first connection port 101, and the first cover 21 is provided with a travel slot 210.

The first connecting piece 3, the first connecting piece 3 is movably arranged along the space of the first mounting box 20, and comprises a pressing nail 30 and a first elastic piece 31. The push pin 30 is composed of a rod 301 and a stopper 302, wherein the stopper 302 is disposed along the outer wall of the rod 301. A first elastic member 31 is sleeved on one side of the stop portion 302, and the elastic member is located between the inner wall of the first mounting box 20 and the stop portion 302, so as to provide an elastic force, so that the rod 301 on the other side of the stop portion 302 can extend out of the through hole into the first connection port 101.

The stopper portion 302 has a first operation portion 3020, and the first operation portion 3020 extends from the stopper portion 302 to one side of the first cover plate 21 and extends out through the stroke groove 210.

Through the structure, the cart door plate can be easily installed and detached. When the first operation portion 3020 is pressed, the lever 301 is lowered, so that the lever 301 is withdrawn from the first connection port 101. After the first operation portion 3020 is released, the force of the elastic member 31 will cause the rod 301 to rebound, and the rod 301 on the other side of the stop portion 302 may extend out of the through hole into the first connection port 101. By controlling the movement of the first operation portion 3020 in the travel groove 210, the mounting process of the cart door panel can be simplified, and flexible disassembly and assembly functions can be provided.

The combination of the lock body 40, the lock lever 41, the operation ring 42 and the second elastic member 43 realizes a reliable fixing and flexible opening and closing function of the door panel 2.

As shown in fig. 1-3, the positioning portion of the cart door panel connection structure includes: a positioning hole 102 is provided in the upper surface of the laminate 1. I.e. holes or protrusions reserved at specific positions on the laminate 1 for achieving accurate positioning of the door panel 2. The lower end of the door panel 2 is provided with a positioning column 201. The positioning column 201 is a protruding portion, and is matched with the positioning opening 102, so as to realize accurate positioning of the door panel 2 in the installation process. When the laminate 1 is engaged with the door panel 2, the positioning posts 201 are inserted into the positioning openings 102, and the two are tightly matched. It is ensured that the door panels 2 are aligned and fixed in the correct position, increasing the stability and reliability of the connection.

Preferably, the first elastic member 31 and the second elastic member 43 are both springs. The first elastic member 31 is used for providing elastic force, so that the rod 301 at the other side of the stop portion 302 can extend out of the through hole into the first connection port 101; the second elastic member 43 allows the locking portion 411 to extend out of the notch groove into the second connection port 103, that is, the first elastic member 31 and the second elastic member 43 can ensure proper elasticity and rebound ability of the connection member during insertion, thereby increasing the fastening and stability of the connection.

Preferably, the first cover plate 21 is fixedly connected with the first mounting box 20 through bolts; the second cover plate 23 is fixedly connected with the second mounting box 22 through bolts.

Preferably, as shown in fig. 7, the operating ring 42 is an annular assembly that is rotatable about its own axis of rotation; the second direction refers to a direction away from the rotational axis of the operation ring 42 away from itself. Specifically, in this direction, the operating ring 42 will extend and form one second operating portion 421; the second operation portion 421 has a pull opening 422, and the pull opening 422 is provided for facilitating the grasping, pushing and pulling operations by the operator using the fingers, and thereby controlling or operating the operation ring 42.
