Referring to fig. 1, when the support mechanism is used as a cover body in a heavy truck, the first support 1 is fixedly arranged on the tool box body 17 and beside the tool box 24, the second support 4 is fixedly arranged on the tool box cover 19, the first support 1 is fixedly arranged in a groove of the tool box body 17, and the second support 4 is fixedly arranged in a groove of the tool box cover 19, so that the tool box cover 19 can be completely embedded into the tool box body 17 when the tool box body 17 and the tool box cover 19 are closed; a hinge 18 is arranged at the joint of the tool box cover 19 and the tool box body 17 so as to realize the relative rotation of the tool box cover 19 and the tool box body 17; the lower end of the tool box cover 19 is provided with a lock ring 20, the tool box body 17 is fixedly provided with a lock body 21, when the tool box cover 19 is closed, the lock ring 20 on the tool box cover 19 is matched with the lock body 21 on the tool box body 17, so that the lock ring 20 falls into the lock body 21 and is locked, and the tool box cover 19 is closed; unlocking of the lock ring 20 and lock body 21 is controlled by the toolbox lock 23.
The working principle is as follows:
when the first connecting rod 2 and the second connecting rod 3 are closed, the supporting section 12 is not contacted with the first support 1; when the tool box cover 19 is opened relative to the tool box body 17, the first connecting rod 2 and the second connecting rod 3 rotate relative to the middle rotating shaft 22 at the same time, namely the two connecting rods rotate outwards at the same time, an included angle formed by the first connecting rod 2 and the third connecting rod 3 at the middle rotating shaft 22 is set to be theta, the straight line section 11 starts to abut against the inner surface of the first support 1 along with the increase of the theta, the first return hook 9 always abuts against the outer side of the straight line section 11, and the first return spring 6 starts to gradually store energy and simultaneously give inward force to the straight line section 11 as the first return hook 9 and the first winding section 10 deform; with the continuous increase of theta, the second connecting rod 3 continues to rotate relative to the middle rotating shaft 22, the second return spring 5 always supports against the second connecting rod 3, the second return hook 5 and the second winding section 10 start to gradually store energy because of deformation, and meanwhile, the second return spring 5 gives inward force to the second connecting rod 3, but the first connecting rod 2 supports against the first support 1 because of the straight line section 11, so that the first connecting rod 2 does not rotate relative to the middle rotating shaft 22 any more; when the tool box cover 19 reaches the highest position and cannot be opened any more, the first connecting rod 2 and the second connecting rod 3 simultaneously play a supporting role, meanwhile theta is the maximum angle, the range of the maximum angle theta is set to be 150-180 degrees, and the angle theta is set to be less than 180 degrees, so that when the tool box cover 19 is closed, an operator can close the tool box cover by applying less pressure; when the tool cover 19 is in the final position, the straight section 11 abuts against the inner surface of the first support 1 to give the whole support mechanism support force, and at the same time, the two return springs simultaneously exert inward force (F1 and F2), so that the middle joint of the two links has a constant inward force, and therefore the two return springs have elastic force to assist the two links to open, and provide certain support assisting force for the support mechanism to support the tool cover 19. When the toolbox lid 19 is closed, the angle θ is less than 180 °, the operator can easily pull the toolbox 19 downward, and the two links can easily close.
When the tool box is opened, the button of the tool box lock 23 is pressed first to unlock the tool box lock 23, the lower edge of the tool box cover 19 is held by hands to push upwards, and the tool box rotates around the hinge 18 to be opened. The support mechanism assembly uses two links with a certain included angle to decompose the elastic force of the return spring, so that the return spring supports the gravity (G) of the cover body and the tool box cover 19 is in an open state. When the tool box cover 19 is closed, the tool box cover 19 is rotated around the hinge 18 by pressing the edge of the tool box cover 19, so that the lock ring 20 falls into the lock body 21 and is locked, and the tool box cover 19 is closed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
