Abstract

The utility model relates to a novel plastic alloy threading joint, which effectively solves the problems that at present, when plastic wire conduits and accessories are connected, the installation is complex, the installing effect is low, the accessories are easy to deform and creep, and the like. The technical scheme for solving the problems is that the novel plastic alloy threading joint comprises a threading pipe head and a lock latch, wherein the threading pipe head is a hollow cavity, the inner wall of the mouth part of the threading pipe head is provided with two symmetrical semi-thread card slots which are in an L shape, the outer wall of the lock latch is provided with a boss which is matched with the semi-thread card slot and has the function of fixing, and the boss on the lock latch and the semi-thread card slot are mutually locked in a matching way by rotating, so that the lock latch of the threading pipe head is fixed with a junction box together. The utility model has simple installation, quickness, convenience, cost saving and high efficiency, and is a creation to the plastic threading pipes and the accessories thereof.

Description

A kind of novel plastic alloy Wire joint

One, technical field

The utility model relates to a kind of novel plastic alloy Wire joint that uses when plastic insulation spool plastic junction box connects.

Two, background technology

Plastic conduit is widely used in every field, since eighties of last century country at the beginning of the eighties in a planned way organize apply chemical building material since, the production of plastics threading conduit and application have obtained the development of advancing by leaps and bounds, and plastics PULL BOX supporting with it and penetration pipe connection fittings thereof have also obtained broad development and constantly brought forth new ideas.Compare with traditional plain conductor pipe and accessory, that plastic wire pipe and accessory have is in light weight, good insulation preformance, good corrosion resistance, installation simple and convenient, does not need advantages such as too many kit; And installation process has been avoided being threaded or fusion weld of trouble, and is swift to operate, saves time, laborsaving.But at present, the very big inferior position that most of plastics threading conduit goes out accessories such as wire terminal is that its mechanical strength is not high enough: usually show comparatively significantly " fragility ", easily injured when being hit, impact resistance a little less than; Bearing strength is lower, deform easily under bigger action of compressive stress, creep, and the line box exists more being threaded to bring inconvenience to installation when being connected with spool.So the mechanical mechanics property that how to reduce fixing link, raising installation effectiveness and accessory is the technical problem of necessary solution for plastics spool and accessory thereof.

Three, utility model content

At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of novel plastic alloy Wire joint, can effectively solve complexity is installed when present plastic wire pipe and accessory connect, installation effectiveness is low and accessory is yielding, the problem of aspects such as creep, the technical scheme of its solution is: the utility model plastic alloy Wire joint comprises penetration pipe tube head and snap close, the penetration pipe tube head is the cavity of hollow, the half-thread draw-in groove that two symmetries are arranged on the mouth inner wall, the half-thread draw-in groove is L-shaped, the boss that plays fixation that matches with the half-thread draw-in groove is arranged on the snap close outer wall, by rotation boss and half-thread draw-in groove on the snap close being cooperated is buckled together mutually, penetration pipe tube head snap close and external connection box is fixed together.The utility model is installed simple, quick and easy and is saved cost, and the efficient height is the innovation on plastics spool and the accessory thereof.

Four, description of drawings

Fig. 1 is a structural perspective of the present utility model.

Fig. 2 is a buckle structure stereogram of the present utility model.

Fig. 3 is a penetration pipe tube head structural perspective of the present utility model.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Provide by Fig. 1-Fig. 3, the utility model comprises penetration pipe tube head and snap close, penetration pipe tube head 1 is the cavity of hollow, the half-thread draw-in groove 3 that two symmetries are arranged on the mouth inner wall, the half-thread draw-in groove is L-shaped, the boss 4 that plays fixation that matches with the half-thread draw-in groove is arranged on snap close 2 outer walls, by rotation boss on the snap close is cooperated with the half-thread draw-in groove and be buckled together mutually.

In order to guarantee result of use, said penetration pipe tube head 1 is cylinder, is evenly equipped with strip reinforcement 5 on the outer wall of upper end; The edge 6 of the oriented outer lug in said snap close 2 upper ends is evenly equipped with groove 7 on the edge periphery wall.

The utility model adopts the polyvinyl chloride resin material by injection mo(u)lding, basis at original UPVC material adds the auxiliary agents such as many good modifier such as impact modifier MBS, have higher impact strength and bearing strength, many excellent properties such as both had that plastic insulation, corrosion-resistant, quality are light, moulding process is simple, cost is lower, anti-pressure ability and creep resisting ability are strong have again the mechanical performances such as intensity near metal, hardness. Thereby effectively overcome the shortcoming of the mechanical strength deficiency of conventional plastic line pipe joint, widened widely the scope of application of plastic wire pipe and accessory thereof. The utility model and existing product ratio, the function that has that not only has general plastics spool outlet-pipe joint, but also had characteristic near metal spool outlet joint, and its cost is low, it is simple to produce, and these aspects all are better than metal spool outlet joint. Simultaneously this product install simple and easy, do not need kit, can on-the-spot directly manual installation, effectively improved efficiency of construction, reduced cost, economic and social benefit is remarkable.
