Abstract
The utility model discloses a connecting screw rod fixed head is adjustable lower margin of refrigerator of first structure of pineapple relates to refrigerator spare part field, including connecting screw rod, plastics nut, last fixed head, circular boss and the screw rod screw thread of being provided with of connecting screw rod, the fixed head design is the first structure of pineapple, the parallel and level is followed outward with connecting screw rod's circular boss to plastics nut inner circle. Connecting screw rod's material adopts through zinc -plated passivation treating's 45# steel. Compared with the prior art, the utility model discloses plastic and the slippage of screw thread in the use have effectively been avoided to process is simple, provides the adjustable lower margin of simple efficient refrigerator, creative solution the difficult problem in the adjustable lower margin production process.
Description
Technical field
This utility model relates to refrigerator parts field, is specifically related to a kind of connect the refrigerator burr adjustable tail margin that screw rod fixing head is Fructus Ananadis comosi header structure.
Background technology
Burr adjustable tail margin is the parts adjusting height conventional in refrigerator, can be regulated the height of refrigerator by the length adjusting screw thread.In use, owing to stress is excessive, traditional positive turret head connects screw rod and easily produces slippage with plastic cap nut.Therefore, on the premise of ensureing that bolt uses and requires, how existing burr adjustable tail margin is connected screw rod and improves to improve its production efficiency and service life becomes urgent problem.
Utility model content
The purpose of this utility model is, low for there is production efficiency in producing at refrigerator burr adjustable tail margin and use, the consuming time is long, the problems such as easy slippage, effectively prevent the slippage during plastic cement produces parcel with screw thread and uses, and technical process is simple, it is provided that a kind of simple efficient refrigerator burr adjustable tail margin.
This utility model be the technical scheme is that a kind of to connect the refrigerator burr adjustable tail margin that screw rod fixing head is Fructus Ananadis comosi header structure, connect screw rod including refrigerator burr adjustable tail margin and use the 45# steel processed through Zincing passivation, prevent from getting rusty, improve intensity and the wearability connecting screw rod.The fixing head connecting screw rod uses uniform Fructus Ananadis comosi header structure, tightr with engaging of plastic cap nut, can increase moment of torsion；Directly using rolled thread to produce during processing Fructus Ananadis comosi header structure, production efficiency is higher.Connecting screw rod and be provided with round boss, when can block injection, the sealant on top flows to screw thread and causes glue bag silk；During injection, mould sleeve outer ring is concordant with round boss, and top is adjacent to round boss, it is to avoid the sealant of sidepiece flows to screw thread and causes glue bag silk.
In such scheme, connecting nut stem material is the 45# steel that Zincing passivation processes.
In such scheme, connect screw rod fixing head and use uniform Fructus Ananadis comosi header structure.
In such scheme, connect screw rod and be provided with round boss.
In such scheme, plastic cap nut inner ring is concordant with the round boss outer being connected screw rod.
The beneficial effects of the utility model are:
(1) connecting screw rod fixing head and use uniform Fructus Ananadis comosi header structure, can increase moment of torsion, processing is simple, and production efficiency is high；
(2) connect screw rod and be provided with round boss, be possible to prevent the sealant on top to flow on screw thread；
(3) connect screw rod and use the 45# steel processed through Zincing passivation, prevent from getting rusty, improve intensity and the wearability connecting screw rod.
Accompanying drawing explanation
Fig. 1 is the front view connecting screw rod；
Fig. 2 is the sectional view of burr adjustable tail margin；
In figure: 1. connect screw rod, 11. fixing head, 12. round boss, 13. screw flights, 2. burr adjustable tail margin, 21. plastic cap nuts.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further.
Shown in reference Fig. 1 ~ Fig. 2, refrigerator burr adjustable tail margin described in the utility model, form including connection screw rod 1 and plastic cap nut 21, wherein connection screw rod 1 is for individually producing, and plastic cap nut 2 is injection mo(u)lding.Connect screw rod 1 to include: fixing head 11, round boss 12, screw flight 13；Fixing head 11 is designed as Fructus Ananadis comosi header structure, can increase torsional moment, is easy to again manufacture.When round boss 12 is possible to prevent injection, the sealant on top flows to screw thread and causes glue bag silk.Material uses the 45# steel processed through Zincing passivation, prevents from getting rusty, and improves intensity and the wearability of bolt.After connection screw rod 1 has manufactured, need to be installed in mould, by injection and plastic cap nut 21 one-shot forming.Injection moulding process is: connecting screw rod 1 and use plug-in to be connected with mould sleeve 3, positioned by interference fits, mould sleeve 3 need to be adjacent to round boss 12, it is to avoid causes glue bag silk owing to pressure effect makes connection screw rod 1 be moved during injection.
Above-described only preferred embodiment of the present utility model, the interest field that certainly can not limit this utility model with this, therefore change according to the equivalence that this utility model claim is made, still belong to protection domain of the present utility model.
