Detailed Description
The inconvenient problem of current drain valve base installation, dismantlement. Therefore, the present invention provides a new solution, and for a clearer representation, the present invention will be described in detail with reference to the accompanying drawings.
Example 1:
referring to fig. 1-8, a mounting device for mounting a fixed member at a mounting opening 21 of a base 20. The mounting device comprises a body 10 of a fixed part, wherein the body 10 is abutted against the front surface of the base 20 when being mounted in the mounting opening 21, the mounting device also comprises a connecting piece 30 and a locking piece 40, a mounting part 11 is arranged on the body 10, and the connecting piece 30 is movably mounted on the mounting part 11. When the body 10 is arranged in the mounting opening 21 of the base 20, the locking member 40 can be driven to move between the unfolding position and the folding position by driving the connecting member 30; when the locking member 40 moves to the unfolded position, at least a part of the axial projection of the locking member 40 along the installation opening 21 extends out of the installation opening 21, and the locking member 40 is pressed against the back surface of the base 20 under the driving of the connecting member 30 so as to lock the body 10 of the fixed member with the base 20; when the locking member 40 moves to the retracted position, the axial projection of the locking member 40 along the installation opening 21 is located in the installation opening 21, so that the locking member 40 can be withdrawn from the installation opening 21, and the body 10 can be detached from the base 20.
Be equipped with on the body 10 and be used for with retaining member 40 rotates spacingly in the first spacing portion 50 of expansion position, it is relative body 10 forward rotation connecting piece 30, connecting piece 30 drives retaining member 40 is relative body 10 forward rotation, until retaining member 40 with the spacing cooperation of first spacing portion 50, first spacing portion 50 prevents the linkage is rotated to connecting piece 30 forward retaining member 40, and then retaining member 40 is in follow under the screw-thread fit of connecting piece 30 the axial motion of connecting piece 30 until press against in the back of base 20.
Be equipped with on the body 10 and be used for with retaining member 40 rotates spacingly to be in the spacing portion 60 of second of position of closing is closed, it is relative body 10 antiport during the connecting piece 30, connecting piece 30 drives retaining member 40 is relative body 10 antiport, until retaining member 40 with the spacing cooperation of the spacing portion 60 of second, the spacing portion 60 of second stops the linkage of the reverse rotation of connecting piece 30 retaining member 40, and then retaining member 40 is in follow under the screw-thread fit of connecting piece 30 the axial of connecting piece 30 is toward keeping away from the back motion of base 20.
