Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: running-board locking fixed knot constructs, including footboard body 1, clamping screw 2, fixed block 3, drive ball 5 and third spring 12, the inside threaded connection of footboard body 1 has clamping screw 2, the external fixed surface of footboard body 1 is connected with fixed block 3, the inboard of fixed block 3 is provided with drive ball 5, the surface laminating of drive ball 5 is provided with member 4, extension board 7 has been established to the inside of footboard body 1, the inside bolt fixedly connected with third spring 12 of footboard body 1, the first spring 6 of the inside bolt fixedly connected with of footboard body 1.
The appearance of fixed block 3 is "C" font, and fixed block 3 forms the integral structure through clamping screw 2 and member 4, and fixed block 3 constitutes revolution mechanic with drive ball 5, through clamping screw 2 to the extrusion of fixed block 3, makes fixed block 3 can wrap up member 4, and then is convenient for the staff to install footboard body 1, has improved staff's installation effectiveness.
Drive ball 5 and wait angle setting in the inboard of fixed block 3, through the rotation of drive ball 5, make people can be faster adjust the position of fixed block 3 on member 4 to make the staff can be faster install footboard body 1.
The accommodating frame 8 and the engaging blocks 10 form a sliding structure, the two sets of engaging blocks 10 form an elastic structure through the second springs 9, the outer surfaces of the engaging blocks 10 are inclined, and the extending plate 7 can be automatically locked when not in use through the engagement of the engaging blocks 10.
The connected mode between the end of third spring 12 and movable block 13 is bolt fixed connection, movable block 13 and bracing piece 11 constitute sliding construction, the connected mode between bracing piece 11 and the footboard body 1 is bolt fixed connection, the inboard radian of bracing piece 11 equals with the surface radian size of movable block 13, through the extrusion to extension board 7, make the deformation of third spring 12, can make movable block 13 resume initial position, thereby make extension board 7 can be better the repetition fixed with loosen, and then the people of being convenient for use extension board 7.
The working principle is as follows: when the pedal locking and fixing structure is used, as shown in fig. 1-4, when the pedal body 1 needs to be installed, the fixing block 3 is sleeved on the outer surface of the rod piece 4, then the fixing screw 2 is rotated to enable the fixing screw 2 to extrude the fixing block 3, so that the rod piece 4 is wrapped and fixed by the fixing block 3, and when the position of the pedal body 1 needs to be adjusted, the fixing screw 2 only needs to be slightly rotated outwards for a plurality of circles to push the pedal body 1 to move, so that the driving ball 5 rotates, and further the operation of people is facilitated;
when the area of the pedal body 1 needs to be enlarged, people squeeze the extension plate 7 with feet, so that the extension plate 7 pushes the clamping block 10 to move, the clamping block 10 slides in the accommodating frame 8 under the blocking of the moving block 13, the second spring 9 and the first spring 6 deform, so that the clamping block 10 retracts into the accommodating frame 8, after the clamping block 10 is positioned at the upper part of the moving block 13, the clamping block 10 restores to the initial position under the action of the second spring 9 restoring deformation, then the extension plate 7 is released, the accommodating frame 8 is ejected under the action of the first spring 6 restoring deformation (the initial state of the first spring 6 is a compressed state), the clamping block 10 drives the moving block 13 to slide on the supporting rod 11, the third spring 12 generates tensile deformation, so that the moving block 13 is attached to the inner side of the supporting rod 11, at the moment, the first spring 6 continuously restores to deform, under the blocking of the moving block 13, the engaging block 10 is retracted into the accommodating frame 8 again, and when the engaging block 10 is located below the support bar 11, the engaging block 10 returns to the initial position, and the extension plate 7 is ejected.
The above is the operation of the whole device, and the details which are not described in detail in this specification are well known to those skilled in the art.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
