The utility model discloses a kind of food production workshop self-closing door, comprise doorframe, door-plate, door-hinge A, door-hinge B, the upper end of door-hinge A is fixed on doorframe 1 with screw, matching with the pipe axle sleeve being welded in door-plate in door-hinge A lower end, between round steel axle and pipe axle sleeve, can freely rotate; The lower end of described door-hinge B is fixed on floor, and door-hinge B upper end connects matches with the pipe axle sleeve being welded in door-plate, between round steel axle and pipe axle sleeve, can freely rotate.By adjusting the setting angle of door-hinge and door-plate, make door-hinge A form the angle of 3 °～5 ° to the vertical line on the axis between door-hinge B and ground, after utilizing door to open, thereby its center of gravity gets a promotion and increases potential energy with the rotation of opening the door, form reverse flywheel moment, rely on the gravity of door automatically to set back, thereby door is closed automatically.The utility model structure design advantages of simple, easy to use, cost is low, is applicable to food production workshop.
Description
Technical field
The utility model relates to a kind of door, is specifically related to a kind of food production workshop self-closing door.This self-closing door is arranged between each regional channel in food production workshop, after being pushed open by go-cart or producers, can slowly close voluntarily.
Background technology
For food production workshop self-closing door, great majority are all just can reach the effect of closing voluntarily by automatic reset device is housed, and mainly comprise and increase mechanical ancillary facility as the device such as spring, closer; Adopt electronic induction means to comprise to install the even facility such as radar of light-operated facility, acoustic control facility, temperature control.So not only increase the cost of door, not environmental protection again, attractive in appearance, and principle complexity, these doors are closed rapidly after being pushed open by small handcart or personnel, and these personnel that very easily cause injure; Even if some door energy slowly closings, its automatic reset device is easy to corrosion for a long time in moist production department, and the cost of maintenance is increased.Adopt existing which kind of method all must bear suitable device and maintenance cost.
Along with the progress of technology, also there are some documents to disclose some doors that can automatically close in recent years, take passages as follows:

Classification number: E05F1/12 (2006.01) I application obligee: Liu Zhiying invention designer: Inventors Unpublished's summary: a kind of self-closing doors, what one end of spring was fixed on switch gate is equipped with hinge on one side, the other end is fixed on body of wall, can under the effect of spring, realize automatic door-closing, simple in structure, easy to use.
2, Chinese patent title: self-closing doors application (patent) number: the CN01262384.9 applying date: 2001.10.29 notice of authorization number: CN2500769Y notice of authorization day: 2002.07.17 Main classification number: E05F1/0 classification number: E05F1/06; E05F7/00 applies for obligee: the invention designer of Qingdao Port Office: Yankee is non-; Guilin three a kind of self-closing doors of making a summary, comprise a body, loose-leaf, be characterized in: described loose-leaf comprises the Upper shaft sleeve that is fixed in Men Tiyi side, be fixed on the Lower shaft sleeve on doorframe and connect the hinge axis core of upper Lower shaft sleeve, the interface of described upper and lower axle sleeve is inclined plane, two inclined planes are identical with the horizontal plane angle number of degrees, when door body is closed, engage completely on the inclined plane of upper and lower axle sleeve.Described hinge axis core upper and lower side respectively arranges one section of screw thread, and upper and lower nut is all housed respectively on it, and hinge axis core bottom overcoat has a Compress Spring, and spring upper and lower side withstands on respectively Lower shaft sleeve bottom surface and lower nut end face.Described door body opposite side arranges one and closes a safety screen, when door body is closed, closes a safety screen external part and just withstands on doorframe inner face.Door body, under gravity and Compress Spring elastic force double action, automatically resets and closes, and in the normally off of safety, exempts operating personnel's troublesome operation of hook conveniently.Simple to operate, safe and reliable.
The document of more than taking passages, although also have the function of automatically closing, can not solve problem noted earlier completely, and spring assembly easily corrosion in a humid environment, loses effect, causes potential safety hazard.
Summary of the invention
The main order of the utility model is for solving the deficiency in technique scheme, a kind of food production workshop self-closing door is provided, this self-closing door's structure design advantages of simple, easy to use, cost is low, can improve producers and small handcart passes through fast, and it is conveniently pushed open, can slowly close voluntarily, can not clash into personnel and go-cart.
Technical scheme is as follows:
A kind of food production workshop self-closing door, comprises doorframe, door-plate, door-hinge A, door-hinge B, the upper end of door-hinge A is fixed on doorframe with screw, and matching with the pipe axle sleeve being welded in door-plate in door-hinge A lower end, between round steel axle and pipe axle sleeve, can freely rotate; The lower end of described door-hinge B is fixed on floor, and matching with the pipe axle sleeve being welded in door-plate in door-hinge B upper end, between round steel axle and pipe axle sleeve, can freely rotate.
Described door-hinge A forms the angle of 3 °～5 ° to the vertical line on the axis between door-hinge B and ground.
Described door-plate is provided with left and right two fan doors, has the gap of 3 mm～8mm between two fan door-plates, and there is the gap of 3mm～6mm on door-plate and ground.
Operating principle of the present utility model is:
By adjusting the setting angle of door-hinge and door-plate, make door-hinge A form the angle of 3 °～5 ° to the vertical line on the axis between door-hinge B and ground, after utilizing door to open, thereby its center of gravity gets a promotion and increases potential energy with the rotation of opening the door, form reverse flywheel moment, rely on the gravity of door automatically to set back, thereby door is closed automatically.
