Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The first embodiment is as follows:

as shown in figures 1-3, the invention discloses a tool box support rod, which comprises a plug 1 and a slot 2 which are clamped by a male connector and a female connector. The plug 1 is arranged on the switch door, and the end part of the plug is provided with a ball head 11 for clamping the slot 2.

The slot 2 is arranged on a hinge rod 3 of the tool box and is directed to a radial opening of the hinge rod 3. The hinged rod 3 is hinged to the box body of the tool box, as shown in fig. 5, the end of the opening and closing end of the hinged rod 3 is provided with a threaded connection clamping head 5, and a locking nut in threaded connection is further arranged to prevent the hinged rod 3 and the clamping head 5 from loosening. The slot 2 is arranged on the chuck 5.

The chuck 5 is also provided with an elastic part 4. As shown in fig. 8, the elastic member 4 has two clamping rods 41 symmetrically disposed, inserted into the clamping head 5, and penetrating through the slot 2 to realize sliding connection. The clamping rod 41 is clamped or separated from the ball head 11 by plugging the elastic piece 4. When clamping, the clamping rod 41 is clamped at two sides of the root part of the ball head 11; when the door is separated, the slot 2 can be smoothly separated from the ball head 11, so that the opening and closing of the door are realized.

The arrangement of the clamping head 5 ensures that the clamping head 5 can be replaced when the elastic piece 4 or the slot 2 is damaged, thereby reducing the cost.

Firstly, opening and closing the door and opening the door, and rotating the hinge rod 3 to ensure that the slot 2 is opposite to the plug 1; then the elastic element 4 is pulled out, so that the elastic element 4 is in a state of being separated from the plug 1; then the switch door is rotated reversely, so that the slot 2 is clamped with the plug 1; finally, the elastic piece 4 is inserted into the clamping head 5 and clamped with the plug 1 to realize the fixation of the plug 1 and keep the opening and closing door in an opening state; when the opening and closing door needs to be opened and closed, the operation is reversed. The invention replaces the traditional gas spring and locking mechanism, and has the advantages of simple structure, convenient operation and low cost.

Example two:

compared with the first embodiment, the differences are as follows: the clamping rod 41 is inserted in the clamping head 5 and is arranged at the opening of the slot 2. The clamping rod 41 is driven to open or close, so that the clamping rod 41 is clamped or separated from the ball head 11. The clamping rods 41 are in the same plane when being opened or closed. Therefore, when the ball head 11 is clamped with the slot 2, the clamping rod 41 is opened under the guiding action of the ball head 11; when the ball 11 is clamped into the slot 2, the clamping rod 41 is reset and clamped at the root of the ball 11, so that the ball 11 is fixed.

Example three:

compared with the two examples, the difference is that: when the clamping rod 41 needs to be opened and separated from the ball head 11, the acting point of the clamping rod is at the joint of the clamping rod 41, which is relatively laborious and relatively difficult to operate, so that, as shown in fig. 4, the slot 2 is provided with the sliding groove 21 with a wedge-shaped section, and the necking end of the sliding groove is arranged at the opening of the slot 2; the initial position of the catch lever 41 is set at the throat of the chute 21. When the ball 11 is clamped with the slot 2, the clamping rod 41 moves to the flaring end of the sliding groove 21 under the pushing of the ball 11 and gradually flares; when the ball 11 is completely clamped into the slot 2, the center of the ball passes over the clamping rod 41, the clamping rod 41 is contracted and reset, and is clamped at the root of the ball 11, so that the ball 11 is fixed. When the ball 11 needs to be separated from the slot 2, the elastic member 4 is pushed to move along the sliding slot 21 to the flared end.

Example four:

compared with the three phases of the embodiment, the differences are as follows: the elastic member 4 further includes an open coupling ring 42, and the latch levers 41 are perpendicular to the coupling ring 42 and are respectively coupled to the open ends of the coupling ring 42. The provision of the coupling ring 42 increases the force application area to facilitate movement of the resilient member 4 towards the flared end of the slide slot 21.

Example five:

compared with the fourth embodiment, the differences are as follows: because when the driving elastic part 4 slides, the driving elastic part is easy to fall off from the hinge rod 3, on the basis, the end part of the clamping head 5 is also provided with a clamping groove 31 which is vertically arranged, and the connecting ring 42 is clamped in the clamping groove 31.

Example six:

compared with the fifth embodiment, the differences are as follows: since the engaging groove 31 blocks the engaging ring 42, it is difficult to drive the catch lever 41, and therefore, the following design is made: the hinge rod 3 is further provided with a notch 32 communicated with the clamping groove 31. Therefore, the slot 32 increases the operating space, and the pry bar is inserted into the connecting ring 42 along the slot 32, so that the elastic element 4 can be driven to slide to the flared end of the sliding groove 21, and the elastic element 4 is separated from the ball 11.

Example seven:

compared with the sixth embodiment, the differences are as follows: the notch 32 is generally formed in a U-shape having a uniform groove depth, which reduces the structural strength of the end of the hinge lever 3, and therefore, as shown in fig. 6 and 7, the groove bottom of the notch 32 is inclined and the portion thereof connected to the catching groove 31 is formed at a low position. So positioned, the high elevation of the slot 32 also provides a fulcrum for the pry bar, thereby facilitating operation.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
