Detailed Description

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 5, fig. 1 is an exploded view of a self-return side door according to the present invention; FIG. 2 is a partial schematic view of FIG. 1; FIG. 3 is a partial cross-sectional view of FIG. 1; fig. 4 is a schematic view of the self-return side door provided by the present invention in a closed state; fig. 5 is a schematic view of the self-return side door of the present invention in the maximum open state.

The utility model provides a from return side door, including side door pipe 1, go up base 3, lower base 4, stay tube 2 and elastic component 5, it is the plate body structure to go up base 3 and lower base 4, stay tube 2 is rectangular cross section body and vertical setting, its upper end fixed mounting is in last base 3, the lower extreme fixed mounting of stay tube 2 is in lower base 4, it can weld or through screw fixed connection, elastic component 5 is located between side door pipe 1 and the lower base 4, the one end of elastic component 5 is installed on side door pipe 1, the other end links to each other with lower base 4, side door pipe 1 is equipped with spacing portion with the junction of last base 3, lower base 4 installs spacing subassembly, for spacing side door pipe 1 is in certain extent internal motion.

When the side door pipe 1 rotates to the position shown in the figure 5, the side door pipe 1 is limited by the upper limiting part and the lower limiting component and cannot rotate continuously to be stabilized; the procedure is reversed when the door is closed. This application simple structure, it is laborsaving to push away a door, and the side door motion is steady, and the reliability is higher.

In a specific embodiment, there is a mounting panel 21 at the upper end fixed mounting of stay tube 2, the bottom of mounting panel 21 is equipped with first stopper 22, it is corresponding, the upper end pivot side of side door pipe 1 is global to be equipped with second stopper 14, reserve the rotation space between first stopper 22 and the second stopper 14, first stopper 22 and second stopper 14 constitute above-mentioned spacing portion, first stopper 22 and second stopper 14 are two cyclic annular pieces that arc length is big or small, and reserve the rotation space between first stopper 22 and the second stopper 14, first stopper 22 utilizes first bush 6 fixed after cooperating with second stopper 14.

When the side door is in a closed state, the first limiting block 22 is in contact with one end of the second limiting block 14 to realize limiting; similarly, when the side door is opened, the first stopper 22 contacts with the other end of the second stopper 14 to realize the stopper.

As shown in fig. 2 and 3, after the first stopper 22 and the second stopper 14 are installed in a matching manner, the first stopper is hinged to the side door pipe 1 by using the first bushing 6, so that the friction force generated when the side door pipe 1 and the support pipe 2 move relatively can be reduced, the friction noise can be reduced, and the abrasion to the side door pipe 1 can be reduced.

Similarly, the lower end of the side door pipe 1 is hinged with the lower base 4 through the second bushing 7, so that the friction force between the side door pipe 1 and the lower base 4 is further reduced, and the noise generated when the door is opened and closed is reduced.

The first end of the elastic piece 5 is hinged on the mounting platform at the lower part of the side door pipe 1 through a shaft pin 8 and a split pin 9, and the second end of the elastic piece 5 is rotatably mounted on the shaft column of the lower base 4 and can rotate around the position C. However, the present invention is not limited to this, and the elastic member 5 may be a compression spring.

In addition, spacing subassembly includes first electronic switch 10, second electronic switch 12, first electronic switch mount pad 11 and second electronic switch mount pad 13, and first electronic switch 10 and second electronic switch 12 pass through the screw installation respectively on first electronic switch mount pad 11 and second electronic switch mount pad 13 to assemble to the base, and first electronic switch 10 cooperates with second electronic switch 12 and is spacing in the motion of predetermineeing the scope with side door pipe 1.

The lower base 4 is also provided with a limiting column 15, so that the side door is balanced when being opened to the maximum due to the fact that the side door touches the limiting column 15, and limiting is further achieved.

The utility model provides a from the theory of operation of return side door does: when the side door is in a closed state, the second electronic switch 12 receives a signal, the elastic piece 5 is in a compressed state, and the side door pipe 1 is kept closed by the elastic piece 5; when the side door pipe 1 is pushed by a hand, the side door pipe is gradually opened by overcoming the pressure of the elastic piece 5, the elastic piece 5 is gradually compressed at the moment, when the side door pipe 1 rotates to be parallel to the gas spring, the elastic piece 5 is compressed to be the shortest, and the elastic force of the elastic piece 5 is the largest at the moment; when the side door pipe 1 exceeds the point, the elastic piece 5 gradually releases pressure, pushes the side door pipe 1 to continuously rotate, does not need people to provide power to enable the side door pipe 1 to rotate, when the side door pipe 1 rotates to the maximum position, the upper end and the lower end of the side door pipe 1 are respectively limited to stop rotating, the upper end and the lower end of the side door pipe 1 reach balance at the moment, and the first switch 10 receives an opening signal; when the side door is closed, the reverse process is carried out, and the second switch 12 receives a closing signal to trigger the reaction.

The core of the utility model is to provide a from return side door, solved the side door and opened the problem that needs operator's both hands to overcome great torsion to it is spacing all to have done machinery at the upper end of side door and lower extreme, when opening the door, plays human guard action, has security and travelling comfort concurrently, and operation experience is better. The self-return side door that this application provided not only is applied to the order picker, can also be applied to and take advantage of transportation equipment such as formula storage car of driving.

It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

It is right above the utility model provides a from return side door introduces in detail. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
