Detailed Description

The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.

The present application provides a collapsible barrier as shown in fig. 1, comprising a vertical bar 10 which is vertically supported to limit the height, and a horizontal bar (21, 22) which is horizontally blocked from passing through, wherein the frame formed by the two symmetrically arranged vertical bars 10 and horizontal bars (21, 22) is a barrier, and a collapsible structure 30 is arranged on the horizontal bars (21, 22), which results in the horizontal bars (21, 22) having a first bar 21 and a second bar 22, and the collapsible structure 30 is arranged between the first bar 21 and the second bar 22.

Example one

As shown in fig. 2-3, the foldable structure 30 includes a first joint 31 and a second joint 32 connected together in an articulated manner, the first joint 31 is fixedly connected to the first rod 21, the second joint 32 is fixedly connected to the second rod 22, and a lock structure is provided on the first joint, the lock can lock the first joint and the second joint to limit the relative rotation of the first joint and the second joint, and the lock can also allow the relative rotation of the first joint and the second joint.

In this example, the first joint 31 and the second joint 32 are each inserted into the first rod 21 and the second rod 22, respectively, and then fixed by rivets or pins penetrating the corresponding rods and the joint body.

In some examples, the first knuckle 31 is integrally formed with the first rod 21 and the second knuckle 32 is integrally formed with the second rod 22.

As shown in fig. 3, the first joint 31 and the second joint 32 are substantially bar-shaped, and the first joint 31 has an arc-shaped structure protruding downwards and laterally at one side in the length direction as shown in fig. 4, the arc-shaped structure is a first arc-shaped portion 311, and the arc-shaped structure of the first arc-shaped portion 311 preferably adopts a semicircle or a major arc. As shown in FIG. 2, the end 310 of the first joint 31 opposite to the second joint 32 is close to the first arc-shaped part 311, the end 310 is arc-shaped (see R in FIG. 4), and a U-shaped opening 3101 shown in FIG. 5 is provided at the end 310, the gap between the opening 3101 is L, and L is less than or equal to 5mm.

As shown in fig. 4, there is a hinge point a on the first joint 31, the hinge point a being located on the first arc-shaped portion 311, and a shaft hole is provided on the first arc-shaped portion 311 at a position corresponding to the hinge point a to receive the hinge shaft.

The first joint 31 has an axis B in the longitudinal direction (horizontal direction), and the hinge point a is located on a first arc portion 311 protruding from the axis B in the longitudinal direction of the first joint 31.

As shown in fig. 6, the first joint 31 also has a space for accommodating the lock 40. As shown in fig. 6, the lock 40 includes an elastic member 41, a locking tongue 42 and an actuating member 43, one end of the elastic member 41 is connected to the first joint 31, the other end of the elastic member 41 is connected to the locking tongue 42, one end of the actuating member 43 passes through the bottom of the first joint 31 and extends into the space to be connected and fixed to the locking tongue 42, one end of the locking tongue 42 passes through the body of the first joint 31, and the first joint 31 provides a hole facing the second joint 32 for the locking tongue 42 to pass through the space.

The actuating member 43 can cause the locking tongue 42 to compress the elastic member 41 under the action of external force to enable the lock 40 to be in the unlocking position, when the locking tongue 42 is far away from the second joint 32, the rotation limitation on the second joint 32 is released, and a user can rotate the first joint 31 or the second joint 32 to rotate around the hinge point a.

Actuator 43 moves lock 40 to the locked position when the external force is removed, i.e. elastic element 41 is extended so that locking tongue 442 protrudes from the hole toward second joint 32, and then locking tongue 42 abuts recess 322, locking second joint 32 in the direction of rotation of second joint 32, prohibiting second joint from rotating about the hinge point.

As shown in fig. 7, the second joint 32 has a hinge portion 320 hinged to the first joint 31, a second arc portion 322 protrudes from the lower side surface of the hinge portion 320, and the hinge portion 320 is inserted into the opening 3101 to be hinged to the first joint 31; the arc wall r is arranged on the hinge portion 320 and protrudes out of the surface of the hinge portion 320, so that after the hinge portion 320 is inserted into the opening 3101, the hinge portion 320 and the opening 3101 can be in clearance fit, the clearance is 0-2mm, the arc wall r is close to the end surface of the end portion 310, the distance between the arc wall r and the end surface of the end portion 310 is also 0-2mm, and the small clearance can prevent the human body from being blocked.

Referring to fig. 2, when the hinge 320 is inserted into the opening 3101, the upper surface of the hinge 320 exposed at the opening 3101 forms a part of the surface of the first knuckle 31 to obtain a smooth surface to avoid being accidentally caught in the gap of the folding structure 30.

As shown in fig. 7, the second joint 32 has an end recess 322 facing the first joint 31, and the recess 322 is used for engaging the lock tongue 42 to prohibit the first joint 31 and the second joint 32 from rotating relatively.

Further, the second joint 32 has a central axis b in the length direction as shown in fig. 7, a hinge point a corresponding to the hinge point a on the second joint is located on the second arc-shaped portion, the hinge point a is coincident with the hinge point a, and the hinge point a is offset from the central axis b.

When the first joint 31 and the second joint 32 rotate, since the hinge points (a, a) are far away from the axes (B, B), so that a protruding arc part exists between the first joint 31 and the second joint 32 as a space, the position of the hinge point on the arc part can determine the relatively close distance between the first joint 31 and the second joint 32. It will be appreciated that the arcuate portions allow the first joint 31 and the second joint 32 to rotate to a relatively parallel position to avoid the first joint 31 crossing or overlapping the second joint 32. And the more the arc-shaped part protrudes, the greater the distance separating the first joint 31 and the second joint 32 when they are rotated to the parallel position.

It can be seen from fig. 4 that the perpendicular distance between the axis B of the first joint 31 and the hinge point a is greater than the distance from the left end edge of the first joint 31 to the axis B, i.e., the hinge point a is located at a position other than the left end edge of the first joint 31. It can be seen from fig. 7 that the perpendicular distance from the axis b to the hinge point a of the second joint 32 is greater than the distance from the right end edge of the second joint 32 to the axis b. This allows the maximum included angle of the first joint 31 and the second joint 32 to be 180 ° and the minimum included angle to be 0 ° when the first joint 31 and the second joint 32 are rotated relative to each other, i.e. the first joint 31 and the second joint 32 can be in a relatively parallel position in the folded state.

The folded structure 30 is shown in fig. 8 in an incompletely folded state, but the first joint 31 and the second joint 32 can also rotate to enable the first rod 21 and the second rod 22 to be closer to each other, and finally the first rod 21 and the second rod 22 are parallel as shown in fig. 9.

Example two

As shown in fig. 10, the first joint 31 and the second joint 32 of the folding structure are combined to form a space 60 for storing the lock, the elastic member 41 of the lock is disposed at a side of the space 60 close to the second joint 32, the locking tongue 42 of the lock 40 abuts against the elastic member 41, one end of the actuating member 43 of the lock 40 is connected to the hinge shaft 50 mounted at the hinge point, the other end of the actuating member 43 abuts against the locking tongue 42, the locking tongue 42 is pushed by the tension of the elastic member 41 to jack up the end of the actuating member 43 connected to the locking tongue 42, so that the end protrudes out of the surface of the first joint 31, and the user can quickly determine the position of the actuating member 43.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
