Abstract
The utility model discloses an axial limiting device for an axle member, which comprises a fixed bracket, and a tubular puller pin arranged between two side edges of the fixed bracket, wherein two side edges of the fixed bracket are respectively provided with a screw, and the screws are connected with an inner hole of the puller pin to ensure that the puller pin is limited between two side edges of the fixed bracket. The puller pin is limited between two side edges of the fixed bracket by using the screws at two sides so that the puller pin can not drop, thus a locking mechanism works safely and reliably, and the defect of the prior art is effectively overcome. The axial limiting device has a simple structure, and is convenient for processing.
Description
Technical field
The utility model relates to the catch gear of mechanical connection, especially relates to a kind of catch gear that is used for the vertical tube of folding bicycle.
Background technology
Folding bicycle obtains liking of consumers in general with the characteristics of its fast folding or expansion.Behind bicycle folding, smaller volume greatly facilitates transportation and storage; Can use safely again after the expansion, be convenient to people's sport and body-building or ride instead of walk.Safe in utilization for ensureing, after launching through the folder bicycle, must use a catch gear that transom is locked fast, make folder be unlikely to open automatically folding, and influence traffic safety.As shown in Figure 1, general catch gear comprises handle 1, is located at the nut pin 2 of handle one upper lateral part, passes the pilot hole of the guide holder 5 of being located at handle 1 bottom through a upper end screw rod 3 and the screw bonded assembly push rod 4 of this nut pin, the lower end of this push rod.The lower end of this handle 1 is articulated in the side of lower adaptor 20 of the upper end of lower standing tube 10; When the top connection 30 of vertical tube 40 lower ends forwards to lower adaptor 20 when overlapping; In the push rod constraint mechanism 50 that turning handle 1 makes the lower surface of push rod 4 compress to be connected on the vertical tube 40 on the constraint pin 6, thereby make that top connection 30 and lower adaptor 20 are closely overlapping---be locked.When backward rotation handle 1, push rod 4 breaks away from constraint pin 6, and lock release so, top connection 30 and lower adaptor 20 just can free foldings.
Consult Fig. 1, the fixed mount in the push rod constraint mechanism 50 is fixed on the vertical tube outer wall, and constraint pin 6 passes the dual-side of fixed mount.For preventing that this constraint pin axial motion from coming off, so on this constraint pin 6, also be provided with an anti-flake 7, sells 6 left and right sides axial motions so that prevent constraint.But after handle 1 comes back rotation, the lower end of push rod 4 just will prevent easily that flake 7 damages, and then constraint pin 6 will axial motion and come off, thereby makes catch gear lose efficacy, and produces potential safety hazard.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of simple, safe and reliable axle part axially stop block that is used for catch gear of processing.
A kind of part axially stop block that the utility model proposes; It comprises fixed mount, is located at the tight lifting pin of the tubulose between this fixed mount dual-side; Said fixed mount dual-side is respectively equipped with a screw; This screw is connected with the endoporus of said tight lifting pin, makes tight lifting pin be limited between the fixed mount dual-side.
More excellent, the external diameter of said tight lifting pin can be greater than the diameter of the through hole on the said fixed mount side, and the screw head of said screw is sunken in the said fixed mount side.
In addition, the external diameter of said tight lifting pin also can be less than the diameter of through hole on the said fixed mount side, and the diameter of the screw head of said screw is greater than the diameter of the through hole on the fixed mount side.
The utility model utilizes the screw of both sides that tight lifting pin is defined between the fixed mount dual-side, so that tight lifting pin can't come off, thereby makes catch gear safe and reliable, has overcome the defective of prior art effectively.The utility model is simple in structure, easy to process.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the cutaway view of existing product;
Fig. 2 is the cutaway view that the utility model preferred embodiment is used;
Fig. 3 is the exploded view of the utility model preferred embodiment;
Fig. 4 is the cutaway view of the utility model preferred embodiment.
The specific embodiment
Fig. 2, Fig. 3 and Fig. 4 show the formation of the utility model preferred embodiment.The axle part axially stop block that the utility model provides, it comprises a U-shaped fixed mount 13, is located at the tight lifting pin 11 of the tubulose between this fixed mount dual-side, is provided with screw thread in the interior circle of this tight lifting pin.Fixed mount 13 dual-sides are respectively equipped with a screw 12, and this screw is connected with the inner hole thread of tight lifting pin 11, make tight lifting pin 11 be limited between the fixed mount dual-side.Screw 12 is fitted with the tight lifting pin two sides.
First embodiment of the utility model; Like Fig. 4 and shown in Figure 5; The external diameter of said tight lifting pin 11 is greater than the diameter of being located at the through hole on fixed mount 13 sides; Then the screw head diameter of screw 12 can less than/equal the diameter of the through hole on fixed mount 13 sides, then the screw head of screw 12 can be sunken in said fixed mount 13 sides, in order to avoid screw head breaks.
Second embodiment of the utility model, the external diameter of said tight lifting pin 11 also can be less than the diameters of being located at the through hole on fixed mount 13 sides, but the diameter of the screw head of screw 12 should be greater than the diameter of the through hole on fixed mount 13 sides.
The utility model utilizes the screw of both sides that tight lifting pin is defined between the fixed mount dual-side, so that tight lifting pin can't axial motion and come off, thereby makes catch gear safe and reliable, has overcome the defective of prior art effectively.The utility model is simple in structure, easy to process.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
