Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A high-safety locking device for a folding handle riser, as shown in figures 1, 2 and 3, comprises an upper seat 1 and a lower seat 2 which are hinged with each other; the surface of the lower seat 2 is movably provided with a first part 21 and a second part 22; the surface of the upper seat 1 is provided with a limiting piece 11 and a positioning hole 12; the first component 21 is matched with the limiting piece 11 in an initial state to lock the relative positions of the upper seat 1 and the lower seat 2; the moving path of the second part 22 corresponds to the position of the first part 21; driving the second part 22 to move, and pushing the first part 21 to disengage from the limiting part 11; a clamping piece 24 is movably arranged on the second part 22; the clamping piece 24 is matched with the positioning hole 12 in the initial state to lock the position of the second part 22; fig. 4 shows a schematic position of the second part 22 in a first stage of opening, and fig. 5 shows the second part 22 continuing to rotate open to push the first part 21 to move; fig. 6 shows an external view of the locking device in a disengaged state of the first member 21; because the first component 21 can be separated from the limiting part 11 only by rotating the second component 22 to push, the problem that the first component 21 is accidentally disengaged when being impacted, collided and the like can be avoided by utilizing the linkage structural design, and the safety of the locking device is obviously improved;

the second part 22 is hinged to the lower seat 2; the second part 22 can realize the position stabilization of itself by a limiting mode such as an elastic part; the angle from the original position to the angle from which the first component 21 is pushed to trigger the disengaging action can be designed to be larger, so that the false triggering probability can be further reduced, and the safety is improved; the end of the second part 22 remote from the centre of rotation can be made longer so that a longer moment arm is obtained when the operator pulls the rotation and more effort is saved when pushing the first part 21.

The clamping piece 24 is of a hook structure; when the second part 22 is in a locked state, the tail end of the clamping piece 24 is correspondingly clamped at the edge of the positioning hole 12; the hook structure can utilize the requirement of the hook structure on the matching angle to realize simple and effective constraint on the rotational freedom of the second part 22.

The clamping piece 24 is an elastic movable part; and applying force to move the clamping piece 24 to drive the clamping piece to be disengaged from the positioning hole 12. The elastic component can use standard components such as a spring and the like, so that when the clamping piece 24 is not acted by external force of an operator, the clamping piece is kept in a matching state with the positioning hole 12 by the pressure of the spring, the structure for locking the position is simplified, and the overall safety of the locking device is improved.

A reset piece 23 is connected between the first part 21 and the lower seat 2; when the first component 21 is in the initial state, the reset piece 23 drives the first component 21 to keep fit with the limiting piece 11; the reset part 23 can keep the first part 21 always matched with the limiting part 11 when not being subjected to the acting force of the second part 22, so that a complex structure of additionally adding redundant limiting accessories is omitted, and the step of opening the locking device is simplified.

The first part 21 is hinged to the lower seat 2; the first component 21 correspondingly turns over when pushed by the second component 22, and is disengaged from the limiting piece 11; the stored energy when the reset key 23 is retracted on itself can be used to drive the first part 21 back to the position of engagement with the stop 11 without being pushed by the second part 22.

The reset piece 23 is a spring; the reset piece 23 drives the mating end of the first component 21 to turn over to be close to the limiting piece 11; the reset member 23 can be functionally realized by using a standard member such as a spring, and is advantageous to control the manufacturing cost.

The other end of the first part 21 opposite to the reset piece 23 relative to the hinge part is provided with a hook 201; the limiting part 11 is a protruding structure matched with the hook 201; the hook structure is utilized to lock and restrain, redundant execution actions of other modes such as bolt fixing and the like are omitted, and the operation of the locking device is faster and smoother.

As shown in fig. 1 and 7, the bottom of the end of the limiting member 11 is provided with an inclined surface 101; when the upper seat 1 rotates towards the locking position, the inclined surface 101 is in sliding contact with the hook 201, and the first part 21 is pressed to rotate and open; when the upper seat 1 continues to rotate, the limiting member 11 will press the hook 201 to reach the matching position with the lower seat 2, and then the hook 21 returns to the initial position again under the action of the reset member 23, so as to lock the limiting member 1; the design of the inclined plane 101 enables the locking action of the first component 21 to be spontaneously completed along with the rotation of the upper seat 1 when the locking device is locked again from an open state, thereby obviously simplifying the operation steps and improving the use efficiency.

The working principle of the locking device of the folding handle vertical pipe is as follows: when the locking device is opened, an operator firstly moves the movable clamping piece 24 to realize the separation from the positioning hole 12; then the second part 22 is pulled to rotate and open, the second part 22 contacts with the first part 21 in the rotating process, and the first part 21 is pressed to rotate so as to enable the hook 201 to be disengaged from the limiting part 11; finally, the upper seat 1 is rotated to fold the vertical pipe structure;

when the locking device is closed, the opening state of the second component 22 is kept, the upper seat 1 is rotated to be matched with the lower seat 2, the hook 201 is squeezed open by the inclined surface 101 in the rotating process of the upper seat 1, and after the hook 201 reaches the matching position of the upper seat 1 and the lower seat 2, the hook 201 is separated from the inclined surface 101 and is matched with the limiting piece 11 again under the driving of the reset key 23 to complete locking; the second part 22 is then rotated and the catch 24 is pushed into engagement with the locating aperture 12 during rotation, thereby completing the closing action of the entire locking device.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
