Description
Technical field
The utility model relates to drive chain field, refers in particular to a kind of mounting or dismounting conveniently, a kind of button blockchain of use safety.
Background technique
Existing bar application number is the 200820115664.2 convenient bicycle chains installed, and this model utility comprises chain pin, chain rod, outer plate and inner plate, and this chain pin wears among chain rod.The chain rod not having a chain pin to be nested with it in chain is threaded connection, and chain pin termination arranges the rotating handle in flat; In transmission, collision rift chain pin can loosen, and chain is disconnected, causes security incident, and for this reason, it is convenient that we have developed a kind of mounting or dismounting, a kind of button blockchain of use safety, thus improve the safety of user.
Model utility content
The utility model object provides a kind of mounting or dismounting convenient to overcome the deficiencies in the prior art, a kind of button blockchain of use safety.
For achieving the above object, the technical solution adopted in the utility model is: a kind of button blockchain, comprises outer plate, inner plate, bearing pin, pin cylinder; The two ends of described outer plate and inner plate are respectively arranged with through hole; The inside of described one group of inner plate is provided with cylinder, the dead in line of the axis of described cylinder and one group of through hole; Groove is provided with in the middle part of described bearing pin; The inside of described pin cylinder is provided with tongue; Described bearing pin and pin cylinder are placed on the left and right side of cylinder respectively, and realize the fixing of outer plate, inner plate and cylinder by groove and the locked of tongue.
Preferably, described bearing pin is stepped, and comprise plunger, pin body, pin tail, the diameter of described plunger is greater than the diameter of pin body and pin tail, and the diameter of pin body is greater than the diameter of pin tail, and described pin body is provided with groove near one end of pin tail; Pin cylinder comprises plunger, shank, and the center of described shank is provided with through hole; The middle part of described through hole is provided with the tongue corresponding with groove.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Button blockchain described in the utility model realizes the fixing of chain by groove with engaging of tongue, and mounting or dismounting are convenient, use safety.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is bearing pin combination schematic diagram in button blockchain described in the utility model;
Accompanying drawing 2 is the overall plan view of button blockchain described in the utility model;
Accompanying drawing 3 is the overall plan view of button blockchain described in the utility model;
Wherein: 1, outer plate; 2, inner plate; 3, cylinder; 4, bearing pin; 5, cylinder is sold.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-3 is button blockchain described in the utility model, comprises outer plate 1, inner plate 2, bearing pin 4, pin cylinder 5; The two ends of described outer plate 1 and inner plate 2 are respectively arranged with through hole; The inside of described one group of inner plate 2 is provided with cylinder 3, the axis of described cylinder 3 and the dead in line of one group of through hole; Described bearing pin 4 is stepped, and comprise plunger, pin body, pin tail, the diameter of described plunger is greater than the diameter of pin body and pin tail, and the diameter of pin body is greater than the diameter of pin tail; Described pin body is provided with groove near one end of pin tail; Described pin cylinder 5 comprises plunger, shank, and the center of described shank is provided with through hole; The middle part of described through hole is provided with the tongue corresponding with groove; Described bearing pin 4 and pin cylinder 5 are placed on the left and right side of cylinder 3 respectively, and realize the fixing of outer plate 1, inner plate 2 and cylinder 3 by groove and the locked of tongue.
During assembling: the engaging force first bearing pin 4 in a pair chain being overcome groove and tongue has released dismounting from the through hole of pin cylinder 5, material strip is arranged on after on sprocket wheel, from dismounting just now by the axis of cylinder 3 respectively with the axis of outer plate 1 one end through hole and the axial alignment of inner plate 2 one end through hole, bearing pin 4 and pin cylinder 5 are being penetrated from the left and right sides of cylinder 3 respectively, realize the fixing of outer plate 1, inner plate 2 and cylinder 3 by groove with engaging of tongue, complete installation.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Button blockchain described in the utility model realizes the fixing of chain by groove with engaging of tongue, and mounting or dismounting are convenient, use safety.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.。
