Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example 1:

as shown in fig. 1 to 6, the self-limiting hinge with a simple structure of the present invention includes a fixed seat piece 1 fixed to a side of a door frame and a movable seat piece 2 fixed to a side of a door leaf, wherein the movable seat piece 2 is shaped like a Chinese character ji with a concave middle portion, the fixed seat piece 1 includes a base plate 11, a through hole 111 is formed in the middle of the base plate 11, a plurality of first screw fixing holes 112 are formed in two sides of the base plate 11, a plurality of second screw fixing holes 211 are formed in two sides of the movable seat piece 2, a fixing pin 3 vertically penetrates through the middle of the movable seat piece 2, a main shaft 4 penetrating through the through hole 111 is rotatably connected to the fixing pin 3, a screw 5 is fixed to a free end of the main shaft 4, and the screw 5 presses a spring 6 on the through hole. In practical application, a plurality of hinges can be arranged between the door frame and the door leaf. Each hinge only comprises a fixed seat sheet 1, a movable seat sheet 2, a fixed pin 3, a main shaft 4, a screw 5, a spring 6 and a plurality of screws for fixing, and the hinge is simple in structure, easy to process and convenient to assemble. The middle of the fixed seat piece 1 protrudes from the door frame, and the movable seat piece 2 rotates around the fixed pin 3 passing through the protruding part. Because the screw 5 presses the spring 6 on the base plate 11, the main shaft 4 always tends to draw the movable seat piece 2 close to the fixed seat piece 1, so when the door leaf is closed, the movable seat piece 2 is attached to the base plate 11 to obtain a stable state; when the door leaf is pushed inwards or pulled outwards by 90 degrees, the movable seat piece 2 is still attached to the base plate 11 to obtain a stable state.

As shown in fig. 1, 4 and 5, the movable seat piece 2 includes a first vertical surface 21a, a first horizontal surface 22a, a second vertical surface 23, a second horizontal surface 22b and a third vertical surface 21b connected in sequence, the first vertical surface 21a and the third vertical surface 21b are coplanar and parallel to the second vertical surface 23, a second screw fixing hole 211 is provided on the first vertical surface 21a and the second vertical surface 21b, and the first horizontal surface 22a and the second horizontal surface 22b are parallel and both provided with a pin hole 221 for passing a fixing pin 3. The middle part of the movable seat piece 2 is in a C-shaped structure connected by the second vertical surface 23, and the main shaft 4 can rotate in the range of about 180 degrees in the front and back direction.

As shown in fig. 4, the first transverse surface 22a and the second transverse surface 22b are protruded at both sides thereof, and the distance from the protruded edge 222 to the axis of the pin hole 221 is equal to the distance from the first vertical surface 21a and the third vertical surface 21b toward the fixed seat piece 1. Because the corner 223 of the protruding edge 222 limits, the spring 6 will compress only when the door leaf rotates, and when the door leaf is at the 0 ° position, the spring 6 will rebound to make the base plate 11 tightly contact with the first vertical surface 21a and the third vertical surface 21 b; when the door leaf is in the position of +/-90 degrees, the spring 6 can rebound to enable the base plate 11 to be tightly attached to the convex edge 222 on one side. In the steady state, the amount of deformation of the spring 6 is the same.

As shown in fig. 4, the protruding edge 222 is curved at a corner 223 near the first vertical surface 21a and the third vertical surface 21 b. When the door leaf rotates, the corner 223 will push against the base plate 11 to rotate, and the corner 223 is set to be arc-shaped, so that the maximum resistance of rotation can be reduced, and the base plate 11 is prevented from being worn too fast.

As shown in fig. 2 and 3, the second screw fixing holes 211 are arranged in an array on the first vertical surface 21a and the third vertical surface 21 b. Each of the first screw fixing holes 211 represents a screw fixing position, so that the movable seat piece 2 can be firmly fixed to the door leaf.

As shown in fig. 4 and 5, the second vertical surface 23 is provided with a third screw fixing hole 321. Two third screw fixing holes 231 are arranged side by side on the second vertical surface 23. Because the door leaf suspension can generate moment, and great pulling force is easily generated on the contact position of the fixed pin 3 and the movable seat piece 2, a fixed position needs to be added on the second vertical surface 23, so that the hinge deformation can be avoided.

As shown in fig. 6 and 7, the fixed seat piece 1 is provided with a sleeve 13 corresponding to the position of the through hole 111 on the surface of the base plate 11 facing the movable seat piece 2, and the spindle 4 passes through the sleeve 13. The shaft sleeve 13 can provide a vertical support for the movable seat piece 2 and guide the main shaft 4, so that the weight is prevented from pressing on the fixing pin 3 and the main shaft 4, and the problem that the fixing pin and the main shaft are easily damaged is avoided.

As shown in fig. 1 to 3, the main shaft 4 has an outer diameter gradually reduced at an end near the anchor pin 3. So that the spindle 4 can be conveniently passed through the through-hole 111.

As shown in fig. 1 to 4, the base plate 11 is provided with a cylindrical portion 12 on a side facing away from the movable seat piece 2, and the cylindrical portion 12 is located on the outer periphery of the spring 6. The cylindrical portion 12 has a shielding function for the spring 6 and plays a certain role in protecting the spring 6.

As shown in fig. 6, the first screw fixing holes 112 are arranged in an array on the upper and lower sides of the substrate 1. This allows the anchor sheet 1 to be firmly fixed to the door frame.

Example 2:

as shown in fig. 7, the difference from embodiment 1 is that: without the cylindrical portion 12, the first transverse face 22a and the second transverse face 22b project on the same side only, with the projecting edge 223 being at a distance from the axis of the pin hole 221 equal to the distance of the first vertical face 21a and the third vertical face 21b toward the fixed seat piece 1. This embodiment is directed to the case where only one-way pushing is required, that is, the flat non-protruding side of the first lateral surface 22a and the second lateral surface 22b has a stop, and the door leaf can only swing to the protruding side of the first lateral surface 22a and the second lateral surface 22 b.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
