A stable door capable of being opened bidirectionally both inwards and outwards

Abstract

The invention relates to a stable door capable of being opened bidirectionally both inwards and outwards. The stable door (11) with a bidirectional opening structure is locked or opened via a locking mechanism. The locking mechanism comprises an outer U-shaped groove (141) and an inner U-shaped groove (142). The two side walls of the outer U-shaped groove (141) are symmetrically provided with a third inlet and outlet opening (146) and a fourth inlet and outlet opening (148), which form a passageway in the horizontal direction. The inner U-shaped groove (142) is located in the outer U-shaped groove (141); the two side walls of the inner U-shaped groove (142) are provided with a first inlet and outlet opening (145) and a second inlet and outlet opening (147), which have no passageway for communicating in the horizontal direction. The inner U-shaped groove (142) and a nut (149) move up and down in a vertical direction by the action of a first air cylinder (143).

Description

technical field [0001] The application date of this invention is September 30, 2014, the application number is: 201410518039.2, and the divisional application of the invention patent application named "an indoor colt exercise machine". The invention relates to a stable door which can be opened bidirectionally from inside and outside. Background technique [0002] Breeding foals usually requires a large enough field, and foals are naturally fond of sports, so they often need to run horses in the wild. [0003] However, raising foals requires a lot of vacant land, which will result in high cost of raising horses, and horse farms have to be moved to extremely remote areas. In addition, some foals are afraid of the cold and cannot be outdoors in winter in the north. For example, desert horses such as Arabian horses are not cold-tolerant, so they are kept in the house in winter when they are raised in cold regions. However, if the foal cannot exercise indoors for a long time, i...

[0003] However, raising foals requires a lot of vacant land, which leads to high cost of raising horses, and horse farms have to be moved to extremely remote areas

In addition, some foals are afraid of the cold and cannot be outdoors in the northern winter. For example, desert horses such as Arabian horses are not cold-tolerant, so they are kept in the house in winter when they are raised in cold regions.

However, if the foal cannot exercise indoors for a long time, it will seriously affect its normal growth and development
