Description
The technical field is as follows:
the utility model relates to a dedicated roll round pin of aluminium door and window shutting accessory.
Background art:
the special roll round pin of aluminium door and window shutting accessory in the existing market has great problem in process of production, if application number is 200980105292.2, the patent technology of name "roll round pin", receive the influence of its structure, the rolling element can only follow the top telescope of the pole of shoulder round pin axle, in order to restrict the rolling element and break away from after the telescope, need carry out the riveting processing, the top of barre is processed into flange structure, the reaming ladder in the cooperation rolling element reaming hole, thereby avoid the rolling element to deviate from, this kind of riveting processing has increased the assembly degree of difficulty and the processing step of product, make product cost higher, the rejection rate is great. In order to adjust the eccentric amplitude, the flange is designed at the bottom of the rod and is in an outer hexagonal shape, so that a tool can be conveniently forked and rotated, and adjustment is achieved.
The utility model has the following contents:
the utility model aims at overcoming the defects of the prior art and providing the special rolling pin for the locking accessory of the aluminum door and window, which has convenient adjustment and low cost.
The purpose of the invention of the utility model can be realized by the following technical scheme: the utility model provides a dedicated roll round pin of aluminium door and window shutting accessory, including the bolt section, round pin axle section and rolling element, bolt section and round pin axle section structure as an organic whole, for the bolt section, the round pin axle section is the eccentric shaft structure, the rolling element suit is on round pin axle section, round pin axle section top is the flange structure, the hole of rolling element divide into cup joints section and reaming section, cup joint section and round pin axle section cooperation, it is fluted to shape in the section of cup jointing, place the spring leaf in the recess, the reaming step and the flange step cooperation of reaming section, it provides the counter bore that the knob instrument injects the rotating to have at round pin axle section top shaping.
After adopting this technical scheme, compare with prior art, this technical scheme has following advantage: through removing the flange among the conventional art, directly design out the flange at round pin shaft section top, the rolling element can be directly worn into just accomplishing the assembly of rolling element from round pin shaft section bottom, and the processing cost is very low, during the regulation, directly injects the knob instrument and just can realize eccentric adjustment, convenient and fast toward the counter bore.
Description of the drawings:
FIG. 1 is a cross-sectional view of the lock rod with a roll pin for the locking assembly of the aluminum door/window of the present invention;
fig. 2 is an exploded view of the roll pin dedicated for the aluminum door/window locking fitting of the present invention.
The specific implementation mode is as follows:
the present technology is further described below with reference to the accompanying drawings.
The dedicated roll round pin of aluminium door and window shutting accessory of this embodiment, including bolt section 1, round pin axle section 2 and rolling element 3, bolt section 1 and round pin axle section 2 structure as an organic whole, for bolt section 1, round pin axle section 2 is the eccentric shaft structure, 3 suits of rolling element are on round pin axle section 2, 2 tops of round pin axle section are flange 4 structures, the hole of rolling element 3 divide into and cup joints section 31 and reaming section 32, cup joint section 31 and round pin axle section 2 cooperation, it is fluted 5 to shape in cup joint section 31, place spring leaf 6 in the recess 5, the reaming step 321 and the flange step 41 cooperation of reaming section 32, it has the hexagon socket head counter bore 7 who offers the knob instrument to inject the rotating to shape at round pin axle section 2 top.
In the technology, the flange in the traditional technology is removed, the flange 4 is directly designed at the top of the pin shaft section 2, so that the rolling body 3 can be directly assembled by penetrating from the bottom of the pin shaft section 1, the spring piece 6 is naturally placed in the groove 5 before the rolling body 3 is assembled, the rolling body 3 can be prevented from falling off by utilizing the reaming step 321 and the flange step 41 after penetrating, and the processing cost is very low. During adjustment, a knob tool is directly inserted into the inner hexagonal counterbore 7 to realize eccentric adjustment, and the adjustment is convenient and fast.
The assembly process is as follows: firstly, the spring piece 6 is placed in the groove 5 on the inner wall of the rolling body 3, the rolling body 3 and the backing ring 8 are sequentially sleeved from the bottom of the bolt section 1, then the bolt section 1 is inserted into the mounting hole 91 of the lock rod 9, the lock ring 10 is transversely inserted into the bottom of the bolt section 1 at the other end of the mounting hole 91, and a clamping groove (not marked in the figure) for clamping the lock ring 10 is required to be machined at the bottom of the bolt section 1, so that the assembly is realized.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. The invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications and variations, including those shown in the drawings and described herein. Therefore, the equivalent changes made according to the shape, structure and principle of the present invention should be covered in the protection scope of the present invention.
