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. 1-3, the detachable bottom fork for vehicles of the present invention comprises a bottom fork body, the bottom fork body comprises a first cross bar 2 and a second cross bar 6, the outer sides of the first cross bar 2 and the second cross bar 6 are both provided with a side bar 1, the front end of the first cross bar 2 is provided with a first mounting block 3, the front end of the second cross bar 6 is provided with a second mounting block 7, the inner side of the first mounting block 3 is provided with a plurality of positioning rods 5, the inner side of the second mounting block 7 is provided with a plurality of positioning holes 13 matching with the positioning rods 5, the inner side of the first cross bar 2 is provided with a butt-joint block 9, the outer wall of the butt-joint block 9 is provided with a buffer groove 11, the inner portion of the buffer groove 11 is provided with a spring 19, the upper end of the spring 19 is provided with a clamping block 12 located in the buffer groove 11, the outer end of the first cross bar 2 is provided with a fixing seat 16 and a second screw 17 penetrating through the fixing seat 16, the second screw 17 is matched with the fixed seat 16 through a thread structure, the first cross rod 2 is internally provided with a connecting rope 18 which penetrates through the buffer groove 11 and one end of which is connected with the fixture block 12, the other end of the connecting rope 18 is connected with the bottom end of the second screw 17, the inner side of the second cross rod 6 is provided with a butt joint groove 14 which is matched with the butt joint block 9, the inner wall of the butt joint groove 14 is provided with a clamping groove which is matched with the fixture block 12, when the structure is used, the side rod 1 and the first installation block 3 are both provided with a plurality of installation holes, so that the structure is fixed at a specified position of a vehicle through screws, as the flat fork body is a common structure in the existing vehicle, the flat fork does not need to be described too much, when the structure is used, the first installation block 3 and the second installation block 7 can be positioned through the mutual matching of the positioning rod 5 and the positioning hole 13, through the mutually supporting of butt joint piece 9 and butt joint groove 14, can fix a position for first horizontal pole 2 and second horizontal pole 6, mutually support through fixture block 12 and draw-in groove, can provide a limiting displacement for butt joint piece 9 in the inside of butt joint groove 14, thereby make first horizontal pole 2 more firm with the butt joint of second horizontal pole 6, when needs are to first horizontal pole 2 and second horizontal pole 6 when tearing open, effect through helicitic texture rotates second screw rod 17, second screw rod 17 can move in fixing base 16 this moment, at this moment second screw rod 17 can stimulate connection rope 18, further connection rope 18 can stimulate fixture block 12, spring 19 is compression state this moment, fixture block 12 just can enter into the inside of dashpot 11, then with strength strike first horizontal pole 2 or second horizontal pole 6 can, thereby make butt joint piece 9 break away from butt joint groove 14, and then make first horizontal pole 2 break away from second horizontal pole 6.

If the fixture block 12 is of a rectangular structure, when the first cross bar 2 and the second cross bar 6 need to be butted, the second screw rod 17 needs to be rotated, so that the fixture block 12 can enter the inside of the buffer groove 11, the operation is troublesome, the time is wasted, the fixture block 12 is of a trapezoidal structure, the inner side of the fixture block 12 of the trapezoidal structure is of an inclined plane structure, and therefore when the first cross bar 2 and the second cross bar 6 need to be butted, the first cross bar 2 is pushed forcibly, and the practicability of the fixture block 12 is improved.

When this structure is in long-term use, it can be ageing to connect rope 18 to can not be abundant cooperate between butt joint piece 9 and the butt joint groove 14 and between locating lever 5 and the locating hole 13, make easily produce slight rocking between first horizontal pole 2 and the second horizontal pole 6, connect rope 18 to be wire rope, wire rope's toughness is high, difficult fracture, and is not fragile, all be equipped with the fastening pad on locating hole 13 and the inner wall of butt joint groove 14, the fastening pad here adopt the rubber pad can, enable to carry out abundant cooperation between butt joint piece 9 and the butt joint groove 14 and between locating lever 5 and locating hole 13 through the rubber pad, and then improved the stability of this structure when using.

Because butt joint piece 9 is the rectangle structure, so inconvenient will butt joint piece 9 insert butt joint groove 14 inside, influence the assembly efficiency of first horizontal pole 2 and second horizontal pole 6, butt joint piece 9's both sides are equipped with guide block 4, be equipped with on butt joint groove 14's the inner wall with guide block 4 complex guide way 15, through guide block 4 and guide way 15 mutually supporting, can provide a guide effect for butt joint piece 9, make butt joint piece 9 can be more smooth insert butt joint groove 14 inside, the front end of guide block 4 here adopt cambered surface structure can to the practicality of this structure has been improved.

Limiting force between the first cross rod 2 and the second cross rod 6 is mainly provided by a spring 19, so that the working load of the spring 19 is increased, the butt joint of the first cross rod 2 and the second cross rod 6 is firmer, the front end of the butt joint block 9 is provided with a screw hole 10, the outer end of the second cross rod 6 is provided with a first screw rod 8 which penetrates through the second cross rod 6 and is matched with the screw hole 10, a limiting effect can be provided between the first cross rod 2 and the second cross rod 6 through the mutual matching of the first screw rod 8 and the screw hole 10, and the working load of the spring 19 is reduced.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
