Description

The clearance type regulator

Technical field

The utility model relates to the technical field of Insert Nut, and more particularly relating to can not only fastening connection two thin-walled member, can also adjust the clearance type regulator of two component spaces.

Background technique

At present, the method that normally adopts riveting is with two fastening connections of thin-walled member, connecting back two thin-walled members is to fit tightly together, and in some present application, as on automobile and medical apparatus, some places be not the riveting that two thin-walled members need be fitted tightly together, but need leave between two thin-walled members on the basis of certain interval, again that two module components are fastening, at present, common way be earlier between two module components pad put the cushion block of a required clearance distance, use riveting or other method that two members are fastening again, at last as required or condition pull down cushion block again, very trouble like this works together, the needs that quite are unfavorable for factory's production line sharp work, only outbiding of having buy state's external structure complicated connect firmly part, so also just strengthened its production cost of products.

The model utility content

The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and easy to use, cost of production is low, fastening effective and clearance type regulator that required gap can be regulated arbitrarily.

The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:

The clearance type regulator comprises Insert Nut, and this Insert Nut is cylindrical shape, the one end is provided with shade, it also is made of cored screw and solid screw, is columniform step hole in the described Insert Nut, is respectively arranged with screw thread on the middle part of this step hole and bottom; One end of described cored screw is provided with shade, and the other end is provided with the holding claw of extending along its axial direction, and the outer installment of this cored screw has screw thread; One end of described solid screw is provided with screw thread; Cored screw is nested with in the Insert Nut inboard by the screw thread of setting on it and the threads engaged at Insert Nut step hole middle part, and solid screw is nested with in the cored screw inboard by the screw thread of setting on it and the threads engaged of Insert Nut step hole bottom.

The silk thread mouth that is provided with on described Insert Nut step hole middle part and the bottom is opposite.

The holding claw and the solid screw that are provided with on the described cored screw closely cooperate.

The holding claw that is provided with on the described cored screw evenly distributes on its circumferencial direction.

The relative the other end of screw thread is provided with the screw tool bore on the described solid screw.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, cost of production is low, easy to use, only need utilize riveting gun that Insert Nut is fastened on the thin-walled member earlier, again with cored screw by being threaded in the Insert Nut, after adjusting the gap of two thin-walled members, at last solid screw being passed cored screw is threaded in the Insert Nut by it, utilize cored screw and solid screw to carry out another thin-walled member fastening, fastening effective, and can regulate arbitrarily according to the size of required gap clearance.

Embodiment

By Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the clearance type regulator, it mainly is made of Insert Nut 1, cored screw 2 and solid screw 3, this Insert Nut 1 is cylindrical shape, the one end is provided with shade 11, in the described Insert Nut 1 be columniform step hole, is respectively arranged with screw thread on the middle part 12 of this step hole and bottom 13, and the diameter of 12 screw threads is greater than the diameter of step hole bottom 13 screw threads in the middle part of this step hole; One end of described cored screw 2 is provided with shade 21, and the other end is provided with the holding claw 22 of extending along its axial direction, and the outer installment of this cored screw 2 has screw thread 23; One end of described solid screw 3 is provided with screw thread 31, and for the ease of screw-driver or other tool operation, the screw thread 31 relative the other ends are provided with the screw tool bore 32 or the screw edge of a knife that inserts for screw-driver on this solid screw 3; Described cored screw 2 is nested with in Insert Nut 1 inboard by the screw thread 23 of its outer installment and the threads engaged at Insert Nut 1 step hole middle part 12, described solid screw 3 is nested with in cored screw 2 inboards by the screw thread 31 of setting on it and the threads engaged of Insert Nut 1 step hole bottom 13, the silk thread mouth that is provided with on described Insert Nut 1 step hole middle part 12 and the bottom 13 is opposite, and the holding claw 22 that is provided with on the cored screw 2 must closely cooperate with solid screw 3, when solid screw 3 is rotated, under this close-fitting effect, cored screw 2 also can follow solid screw 3 to rotate together, the holding claw 22 that is provided with on the described cored screw 2 evenly distributes on its circumferencial direction, and 4 among Fig. 4 and 5 is designated as two thin-walled members respectively.

During use, utilize riveting gun that Insert Nut 1 is fastened on the thin-walled member earlier, then cored screw 2 is screwed in the Insert Nut 1, again solid screw 3 is passed in the cored screw 2 and be spun on the Insert Nut 1, adjust the gap of two thin-walled members, rotate solid screw 3 with screw-driver, cored screw 2 also can be along with solid screw 3 is rotated together under the effect of its holding claw 22, at this moment, solid screw 3 can slowly move to the inside, simultaneously, because the screw thread at step hole middle part 12 is opposite with the silk thread mouth of its underpart 13 in the Insert Nut 1, cored screw 2 will slowly move on the contrary laterally, when cored screw 2 is stopped by another thin-walled member, cored screw 2 just can't move laterally again, and the solid screw 3 of this moment still can continue to move to the inside, and is with cored screw 2 that another thin-walled member is fastening up to the end of solid screw 3.
