Detailed Description

in order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

in the description of the present invention, it is to be understood that the positional and orientational relationships indicated as "upper", "lower", "left", "right", "front", "rear", "vertical", "bottom", "inner", "outer", etc. are based on the positional and orientational relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

as shown in fig. 1 to 5, an automatic closing door includes:

the door comprises a door frame 1, wherein one end of the door frame 1 is provided with a rotating shaft 11, and the rotating shaft 11 is fixedly connected with the door frame 1;

A shaft sleeve 21 is arranged on the door leaf 2 corresponding to the rotating shaft 11, the shaft sleeve 21 is fixedly connected with the door leaf 2, the shaft sleeve 21 is sleeved on the rotating shaft 11, and the first end of the rotating shaft 11 extends out of the shaft sleeve 21, namely the length of the rotating shaft 11 is greater than that of the shaft sleeve 21;

The torsion spring 3 is sleeved on the rotating shaft 11, two ends of the torsion spring 3 respectively abut against the surfaces of the door leaf 2 and the door frame 1, the main part of the torsion spring 3 is in a spring shape, and supporting bars radially extend from the upper end and the lower end of the main part;

The blocking sleeve 4 is detachably connected with the rotating shaft 11.

So, the both ends of torsional spring 3 support respectively and lean on the surface at door leaf 2 and door frame 1, it is rotatory to drive the one end of torsional spring 3 as the rotation of door leaf 2, make torsional spring 3 take place to twist reverse production torsion, when door leaf 2 does not receive external force, torsional spring 3's torsion makes torsional spring 3's tip exert force to door leaf 2, make door leaf 2 rotatory to the normal position towards opposite direction, thereby realize the automatic closed function of door leaf 2, when door leaf 2 does not need automatic closed function, dismantle blocking sleeve 4 get off, then dismantle torsional spring 3 can, thereby conveniently control door leaf 2 whether have self-closing's function.

In addition, the door further comprises a limiting piece 5, the limiting piece 5 is located on one side of the door leaf 2, the limiting piece 5 is detachably connected with the rotating shaft 11, an inclined surface 51 is arranged on the limiting piece 5, and the inclined surface 51 faces the door leaf 2. Thus, when the door 2 rotates to contact the inclined surface 51, the door 2 cannot rotate, and the torsion spring 3 is prevented from being damaged due to the excessive compression of the torsion spring 3 caused by the excessive rotation of the door 2. The bottom of the limiting member 5 is provided with a prism 52, the rotating shaft 11 is provided with a through hole with the same cross section shape as the prism 52, and the prism 52 penetrates through the through hole.

in addition, a baffle ring 12 is arranged around the inner ring of the door frame 1, and an elastic gasket 13 is arranged on one side of the baffle ring 12, which is in contact with the door leaf 2. Thus, at the instant when the door 2 abuts against the door frame 1, the elastic pad 13 can prevent the door 2 from directly colliding with the door frame 1 to generate excessive noise.

In addition, the two ends of the torsion spring 3 are sleeved with the elastic sleeves 31, so that the damage to the surfaces of the door leaf 2 and the door frame 1 caused by the two ends of the torsion spring 3 can be avoided.

In addition, still include bracing piece 6, bracing piece 6 is located between the rotation end of door leaf 2 and the inboard of door frame 1, and the one end and the door frame 1 threaded connection of bracing piece 6, the other end of bracing piece 6 supports and leans on the side of door leaf 2. In this way, by adjusting the length of the support bar 6 extending out of the door frame 1, the one end of the torsion spring 3 can press the door 2 against the end of the support bar 6, so that the door 2 is relatively fixed, and the door 2 is maintained at a fixed opening angle, and therefore, by adjusting the length of the support bar 6, the opening angle of the door 2 can be adjusted.

in summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
