Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The accommodation groove 21, the groove 19 and the insertion hole 20 which are present in this embodiment are all shown with reference to fig. 1.
The first embodiment is as follows:
as shown in fig. 2, an anti-drop screw assembly includes a screw body 1 and a limiting member 2 screwed on the screw body 1. Screw body 1 passes from the central point of locating part 2 and puts, and the homogeneous integrated into one piece in both ends has the joint piece 3 that is the rectangle about locating part 2, and the joint piece 3 at both ends is the symmetry and sets up and all is close to the upper end of locating part 2.
As shown in fig. 2 and 3, the lower side wall of the clamping block 3 is provided with a smooth and flat plane 4, when the clamping block 3 is placed in the groove 19, the clamping block 3 can be attached to the groove wall of the groove 19 through the plane 4, so that the locating part 2 can be more stable. One end lateral wall of locating part 2 sets up to level and smooth contact surface 8, places in recess 19 through joint piece 3 when the both ends with locating part 2, and contact surface 8 can laminate with the cell wall of recess 19. And the lateral wall that locating part 2 deviates from contact surface 8 is glossy cambered surface 9 to leave the clearance between the cell wall of cambered surface 9 and recess 19, thereby can conveniently take out locating part 2.
As shown in fig. 3, a latch 10 for being inserted into the insertion hole 20 is integrally formed on a lower end side wall of the limiting member 2, and an axial line of the latch 10 overlaps with an axial line of the limiting member 2. Arc chamfers 11 are formed on the side walls of the two ends of the fixture block 10, the fixture block 10 is aligned with the insertion hole 20 and inserted into the insertion hole, so that the limiting part 2 is more stable, and the chamfers 11 can be more smooth when the limiting part 2 is taken out.
As shown in fig. 3, the end of the screw body 1 is fixedly connected with a cylindrical limiting block 5, the limiting block 5 is located on one side of the contact surface 8, and the maximum diameter of the limiting block 5 is greater than that of the screw body 1. The limiting block 5 is provided with an abutting surface 6 on the side wall of one end departing from the limiting part 2, and the abutting surface 6 is used for abutting against the surface of the part. Four contact blocks 7 are integrally formed on the abutting surface 6, and the contact blocks 7 circumferentially surround the abutting surface 6. The contact block 7 roughens the abutment surface 6, so that the friction force of the abutment surface 6 with the surface of the part can be enhanced.
As shown in fig. 2 and fig. 3, an annular inclined surface 13 is provided on a side wall of one end of the limiting block 5 facing the limiting block 2, and a lower end of the inclined surface 13 gradually inclines toward a direction close to the axial line of the screw body 1 and is connected to an outer side wall of the screw body 1. One end of the screw body 1, which is far away from the limiting block 5, is provided with a cross groove 12 for inserting a screwdriver, and the cross groove 12 can be used for conveniently inserting the screwdriver and screwing the screw body 1.
The specific effects of the embodiment are as follows:
when the part in the work piece needs to be fixed, screw body 1 is twisted in locating part 2 earlier, and locating part 2 that will transfer well again inserts respectively in the recess 19 that corresponds through the joint piece 3 at both ends, then inserts fixture block 10 with locating part 2 lower extreme in jack 20 to just can tentatively fix locating part 2. When placing the part in the work piece, make stopper 5 and one end of part carry out the butt through screwing up screw body 1 to just can fix the part in the work piece. Because the maximum diameter of stopper 5 is greater than the maximum diameter of screw body 1 to even in the operational environment of vibrations, screw body 1 can firmly be fixed in locating part 2 one side under stopper 5's effect, avoided the condition that screw body 1 drops from the work piece.
Example two:
as shown in fig. 4 and 5, different from the embodiment, a receding groove 14 is formed in a side wall of one end of the screw body 1 away from the limiting block 5, and the receding groove 14 is disposed at a central position of the side wall of the screw body 1. And the two end side walls of the screw body 1 are penetrated by the receding groove 14.
As shown in fig. 4 and 5, two rotating plates 15 are disposed in the retreat groove 14, and the axial lines of the two rotating plates 15 overlap. The ends of the two rotating plates 15 far away from each other are respectively connected to the groove wall of the receding groove 14 in a rotating manner. The side walls of the two rotating plates 15 at the ends close to each other are arc-shaped surfaces 18 protruding outwards gradually, and the center positions of the two arc-shaped surfaces 18 are abutted against each other. Thereby, the fixing of the two rotating plates 15 is achieved.
As shown in fig. 4 and 5, the upper side walls of the two rotating plates 15 are fixedly connected with contact plates 16 which are oppositely arranged, and the contact plates 16 are vertically arranged on the rotating plates 15. Arc grooves 17 are formed in the side walls of the two ends of the contact plate 16, and the upper and lower end groove walls of the arc grooves 17 are gradually sunken towards the central position.
The specific effects of the embodiment are as follows:
when needs were twisted screw body 1 and are moved, open to both ends through following the groove 14 that moves back respectively with two rotor plates 15 to turn rotor plate 15 and be horizontal position, rotor plate 15 just can provide the stress point for the user, and the user just can conveniently rotate screw body 1 through twisting rotor plate 15, need not make the operation more convenient with the help of other instruments during the use.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
