[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the embodiment, Figure 1-3 A door contactor self-reset button is given, comprising a cover plate 1, the inner side of the cover plate 1 is threadedly connected with four positioning bolts 2, the inner side of the cover plate 1 is fixedly connected with a column sleeve 3, the inner side of the column sleeve 3 is slidably connected with a column 4, the top of the column 4 is fixedly connected with a button 5, the bottom end of the column 4 is fixedly connected with a connecting head 6, an elastic member 7 is arranged on the outer side of the column 4, a placement groove 8 is opened on the inner side of the column sleeve 3, the top of the elastic member 7 contacts with the upper top surface of the placement groove 8, the bottom end of the elastic member 7 contacts with the top surface of the connecting head 6, the inner side of the connecting head 6 is threadedly connected with a fixing bolt 9, the outer side of the fixing bolt 9 is threadedly connected with a nut 10, the outer side of the fixing bolt 9 is sleeved with a gasket 11, the gasket 11 is located between the connecting head 6 and the nut 10, the outer side of the fixing bolt 9 is sleeved with a connecting ring 12, and the connecting ring 12 is located on the inner side of the connecting head 6.

[0020] Through the above settings, the connecting ring 12 is connected to the contactor body, and the cover plate 1 is installed in the wall through four positioning bolts 2. After pressing the button 5, the column 4 slides along the inner side of the column sleeve 3, and the elastic member 7 is in a compressed state, thereby driving the connecting head 6, the connecting ring 12 and the contactor body to move, and the contactor opens the door lock. After releasing the button 5, the elastic action of the elastic member 7 drives the connecting head 6, the connecting ring 12 and the contactor body to reset, and the contactor closes the door lock. If the connection between the connecting ring 12 and the contactor body is damaged, the fixing bolts 9 and nuts 10 can be removed, and the connecting ring 12 can be replaced in time and welded to the contactor body. It should be noted that the gasket 11 plays a role in increasing friction to make the fixation tighter.

[0021] Reference Figure 1-3 , wherein the elastic member 7 is a return spring;

[0022] Reference Figure 1-3 , wherein the outer side of the column sleeve 3 is threadedly connected with a top screw 13, a limiting groove 14 is provided on the column body 4, and the top screw 13 is slidably connected to the inner side of the limiting groove 14;

[0023] With the above-mentioned structural arrangement, the top screw 13 is rotated to insert the top screw 13 into the inner side of the limiting groove 14 , so that when the button 5 is pressed, the maximum pressing distance becomes smaller, thereby increasing the service life of the elastic member 7 .

[0024] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
