The installation of a pin shaft is commonly found in the manufacture of daily life and industrial equipment, the direct rotary connection of two assembly parts can be realized by adopting the pin shaft assembly, in the field, some installation parts do not need very tight assembly precision, the rapidness and convenience of assembly are very emphasized, however, the existing pin shaft limiting installation mode mainly adopts the nut to screw down or insert a safety pin for limiting installation, and the existing installation mode has the problems of complex installation, high assembly cost and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a structural design is reasonable, installs the mounting structure of convenient round pin axle and adopts the stool of its manufacturing.

The utility model provides a technical scheme that above-mentioned problem adopted is: the mounting structure of round pin axle, the round pin axle includes axostylus axostyle and the enlarged spindle nose of relative axostylus axostyle, the spindle nose is fixed continuous with axostylus axostyle one end, still including the installed part that need set up the round pin axle, the installed part is equipped with can supply axostylus axostyle male shaft hole, the installed part is equipped with two separation blades, two separation blades set up the both sides at the axis in shaft hole respectively, but have the space of holding spindle nose between the outer fringe in separation blade and shaft hole, the clearance has between two separation blades, when no exogenic action, the size in clearance is less than spindle nose external diameter, when the round pin axle sets up the installed part, the axostylus.

The blocking piece is provided with an inclined plane which extends from the outer side of the axis to the axis, and one end, far away from the axis, of the inclined plane is far away from the shaft hole relative to one end, close to the axis, of the inclined plane.

Wherein, installed part and separation blade all are the working of plastics, and separation blade integrated into one piece is at the installed part.

The utility model provides a stool, includes the mounting structure of round pin axle, and the installed part is the bench panel of stool, is equipped with the shaft hole on the bench panel, still includes a driving part, and the driving part is equipped with another shaft hole, and the shaft hole of bench panel and the shaft hole of driving part are worn to establish by the axostylus axostyle of round pin axle, and the separation blade resets after the separation blade is crossed to the spindle nose, and the spindle nose falls between shaft hole.

Compared with the prior art, the utility model, have following advantage and effect: when the pin shaft is installed, the pin shaft is pushed forcefully to prop open the blocking piece and fall, and then the pin shaft can be installed in a limiting mode, and the assembling efficiency is greatly improved.

Fig. 2 is a schematic structural diagram of the stool according to the embodiment.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples

As shown in fig. 1-2. The mounting structure of the axis pin, the axis pin 12 includes the axostylus axostyle 1 and the expanded spindle nose 2 of the relative axostylus axostyle 1, the spindle nose 2 is fixedly connected with an end of the axostylus axostyle 1, also include the installed part 3 that needs to set up the axis pin 12, the installed part 3 is equipped with the shaft hole 30 that can be used for the axostylus axostyle 1 to insert, the installed part 3 is equipped with two separation blades 31, two separation blades 31 are set up in both sides of the axis a of the shaft hole 30 respectively, the separation blade 31 is set up in the outside of the shaft hole 30 adjacently, have the space that can, the size of the clearance d is larger than the outer diameter of the shaft lever 1 and smaller than the outer diameter of the shaft head 2, when the pin shaft 12 is arranged on the mounting piece 3, the shaft lever 1 passes through the gap d and is inserted into the shaft hole 30, external force is applied to expand the size of the gap d, the shaft head 2 is reset through the baffle 31 and the baffle 31, and after the baffle 31 is reset, the shaft head 2 falls between the shaft hole 30 and the baffle 31. In this embodiment, the gap d between the two blocking pieces 31 can be slightly changed, and in specific implementation, the blocking pieces 31 are made of a plastic material, preferably a plastic material with good toughness. Further preferably, the mounting member 3 and the stopper 31 are both made of plastic, and the stopper 31 is integrally formed with the mounting member 3. When the spindle head 2 passes through the blocking piece 31, the blocking piece 31 is broken off by hand, or the spindle head 2 is forced to extrude the two blocking pieces 31, the gap d between the two blocking pieces 31 is enlarged, the spindle head 2 can pass through the wrapping clamp of the two blocking pieces 31, after the spindle head 2 passes through the two blocking pieces 31, the blocking pieces 31 are elastically reset, the gap d is reduced, and the blocking pieces 31 block the way of the pin shaft 12 to limit the pin shaft between the shaft hole 30 and the blocking pieces 31.

In this embodiment, the blocking piece 31 is provided with an inclined surface b extending from the outside of the axis a to the axis a, and one end of the inclined surface b far from the axis a is far from the shaft hole 30 relative to the end near the axis a. Under this structure, two flaps 31 are the horn mouth type setting, and the interval between two flaps 31 diminishes by big, and the distance that hinders spindle nose 2 to pass through is just very little, is convenient for it to pass.

Stool, include the mounting structure of round pin axle 12, installed part 3 is the deck plate of stool, is equipped with shaft hole 30 on the deck plate of stool, still includes a driving part 4, and driving part 4 is equipped with another shaft hole, and shaft rod 1 of round pin axle 12 wears to establish shaft hole 30 of deck plate of stool and the shaft hole of driving part 4, and separation blade 31 resets after separation blade 31 is crossed to spindle nose 2, and spindle nose 2 falls between shaft hole 30 and separation blade 31.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
