Abstract

The utility model relates to the improved structure of the combined base. The circumference sutural margin walls of the upper and the lower hood covers are respectively provided with a plurality of embedding strip in equal interval distribution, which is convenient for directly extruding and pushing to butt into the base. The center of the utility model is provided with a jack which is used for installing and matching.

Description

Improved structure of combined base

The utility model relates to the improvement structure of combined type base; It is connecing with variograph and is tipping the row combination in by making several chimeric profiles on the ring of the two upper and lower cover caps week commissura wall, thereby the installation that its is suitable for various bridges cooperates.

General as square understructure under light fixture, fan and the decoration, the inner space that its production method ties up to two moulds is filled the thermal viscosity material and is formed a plurality of convex pillar parts and form base housing so that be adhered together, material such as cement injection or iron sand filling in base shell more afterwards, to increase bottom weight and to make steadily of centre of gravity, thereby reason is not installed the plant bridge and is toppled over.Yet, must control the time suitablely in this working process, accurate, too much stick to inlet and form to destroy and cause influencing whole outward appearance and be support swollen the rising of drum and must scrap otherwise can produce the cement that poured into or the husky loading of iron.Moreover, when combination, because the pedestal of its upper die tooling formation is still seen the made shrinkage pool of leaving on the projection end, in order to cover the undesirable appearance after this outward appearance is made, for attractive in appearance be again cover cap one panel then, then a fabricating cost such as working equipment, personnel operation, installation time, check and parking space also increases thereupon, makes industry feel puzzlement deeply endlessly in fact but thus.

Because above existing the making for this type of base has its some defectives and be difficult for suitably control, the inventor satisfies according to actual conditions, concentrates on studies and gathers the experience of produce and market for many years, develops the utility model then finally.

The utility model main purpose is to provide a kind of improvement structure of combined type base; To overcome the defective of prior art.It respectively is shaped on several uniform chimeric profiles on the ring of two upper and lower cover caps week commissura wall, and the pipe box post towards convex dews is arranged on the central position, so as directly extrusion push connect button and form base after, be convenient to plug cooperation be installed.

Another purpose of the present utility model is to provide a kind of improvement structure of combined type base; Wherein, also can be in two upper and lower cover caps face be shaped on pipe box post towards convex dew so that by the combination of screw threads lock.

Now with regard to structure characteristic of the present utility model and operation etc., join after accompanying drawing is described in more detail in.

Fig. 1 is the three-dimensional exploded view of the utility model structure.

Fig. 2 is the sectional view of the utility model combination clinching.

Fig. 3 is the view of another combination interlocking of the utility model.

At first, please referring to shown in Figure 1: the improvement structure of a kind of combined type base of the utility model; It ring

week commissura wall

11,21 of

cover cap

1,2 about in the of two of molding and forming have be etc. between several uniform chimeric profiles 111,211, and pipe box post 112,212 towards convex dew is arranged on the central position of each cover cap; Like this, after these

cover cap

1,2 moulding, can directly its two body be pasted to stagnate via chimeric profile 111,211 clinchings of all

commissura walls

11,21 of ring and realize combination (as Fig. 2), so that can form the base that is applicable to various types of plug-in mountings.In addition, also can be in two upper and

lower cover caps

1,2 face be shaped on pipe box post 2A towards convex dew, promptly as shown in Figure 3; So that up revolving lock, makes up by screw.

In sum, the utility model and common structure have the characteristics of stable bond and simple for production and improved utilization ratio more really.

Claims

1, a kind of improvement structure of combined type base is characterized in that, it on the ring of upper and lower cover cap week commissura wall, respectively be provided be wait between several uniform chimeric profiles, and pipe box post towards convex dew is arranged on the central position, with the crowded composition of putting of clinching directly.

2, the improvement structure of a kind of combined type base according to claim 1; It is characterized in that face has towards the sleeve column of convex dew in upper and lower cover cap, so that the combination of screw threads lock.
