Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
As illustrated in fig. 1 and 2, the pin axle locking structure that the utility model provides comprises clamp 1, bearing pin 2 and link 6, wherein,
Bearing pin 2 can be arranged in the attachment hole 4 of connecting body 3, described bearing pin is formed with draw-in groove 5 in circumferential direction, link 6 can be fastened on described clamp 1 on described connecting body 3, simultaneously, on clamp 1, be formed with through hole, this through hole comprises the assembly department 7 penetrating for described bearing pin 2 and the limited part 8 that can coordinate with described draw-in groove 5, and described assembly department 7 is interconnected with described limited part 8.
Like this, while installing by 2 pairs of connecting bodys of bearing pin 3, bearing pin is inserted in the attachment hole 4 of connecting body, bearing pin is passed from the assembly department 7 of clamp, then pull clamp, for example along the illustrated direction of arrow, pull clamp, making the limited part 8 of clamp and the draw-in groove of bearing pin form card coordinates, if needed, due to coordinating of limited part and draw-in groove, the bearing pin of take rotates clamp as fulcrum, after forwarding required mounting point to, clamp with link, clamp is fastened on described connecting body, like this, limited part matches with the side of draw-in groove, with restriction bearing pin axial float, simultaneously, limited part coordinates with the bottom surface of draw-in groove, with restriction bearing pin, rotate.And when dismounting, only need link to take off, oppositely promote clamp, just clamp can be taken off from bearing pin, therefore, and this locking mechanism easy accessibility of bearing pin, simple in structure.
Certainly, connecting body 3 is not limited to the structure shown in Fig. 1, and connecting body 3 can be any parts that need bearing pin to connect, and it can have any shape.
As long as the structure of the assembly department 7 on clamp 1 and size can meet bearing pin 7, pass, it is not specifically limited.For can be corresponding with the shape of bearing pin, and be convenient to moulding, preferably, as illustrated in fig. 1 and 2, described assembly department 7 is circular arc, and described limited part 8 is for straight line type and have identical symmetrical center line with described assembly department 7.Like this, the straight flange of limited part 8 can be engaged in the draw-in groove 5 of bearing pin 2.
More preferably, in order to coordinate more closely with the draw-in groove of bearing pin at limited part 8, as shown in Figure 2, the end relative with described assembly department 7 of described limited part 8 forms the circular arc part 9 that can fit with the outer circumferential face of described bearing pin 2.
In addition, after the limited part 8 of clamp coordinates with the draw-in groove 5 of bearing pin, in order to prevent that bearing pin from rotating, and can effectively make clamp drive bearing pin to rotate, described draw-in groove 5 is straight trough, and namely, the bottom surface of draw-in groove 5 is flat shape.Like this, after clamp coordinates with bearing pin, if clamp, not in mounting point, rotates clamp, clamp can be defined as untie-sell axle and rotate, until clamp turns to its required mounting point.
In addition, be formed with the mounting hole 10 of at least two on described clamp 1, described link 6 passes described mounting hole 10 so that described clamp 1 is fastened on described connecting body 3.At this, link 6 can be pin of bolt, screw or taper etc., now, need on connecting body 3, form the hole corresponding with mounting hole on clamp.
Preferably, the described mounting hole 10 of at least two is formed on the end of close described assembly department 7 of described clamp 1.At least two mounting holes 10 can be arranged around described assembly department 7.Like this, only by link 6, clamp is fastening in an end of clamp, another end of clamp (being formed with the end of limited part) is the structure for sealing, thereby by simple connection, just can realize the reliable location of clamp, can guarantee again the fastening strength that clamp is spacing to bearing pin.
In a kind of mode of execution, on an end of bearing pin 2, be formed with and stop cap, can be resisted against when bearing pin is installed on another side of connecting body, and on another end of bearing pin 2, being only formed with a draw-in groove, the coordinating of the limited part by this draw-in groove and clamp prevents that bearing pin from rotating and axial float.
In another embodiment, described draw-in groove 5 is two, and Parallel Symmetric be formed on the same end of described bearing pin 2, namely, on an end of bearing pin 2, be formed with the described cap that stops, and on another end of bearing pin 2, Parallel Symmetric ground is formed with two draw-in grooves 5, these two draw-in grooves 5 are preferably straight trough, by two draw-in grooves, can realize spacing cooperation that bearing pin is better with clamp.
In a preferred embodiment, as shown in Figure 1, parallel and be formed with symmetrically two described draw-in grooves 5 and by described clamp 1 and described link 6, locate respectively respectively on two ends of described bearing pin 2, thus on two sides of connecting body, realize the spacing of bearing pin.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
In addition, between various mode of execution of the present utility model, also can carry out combination in any, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
