Abstract

The utility model discloses a water tank which comprises a body and a joint, wherein the body is provided with an opening, and at least one fusion splicing rib is arranged on an external rotative surface of the joint and spliced with the opening of the body in a fusion manner. The fusion splicing ribs are spliced with the opening of the body into an indivisible whole in a fusion manner; no gap exists between the joint and the body; the sealing effect is very good; no leakage exists; and the joint is connected with the body quite securely, and does not fall off easily. When a blank is formed, the joint is spliced with the blank in a fusion manner, additional processing procedures are not required, the manpower is reduced, and the production cost is lowered greatly. The fusion splicing ribs are arranged continuously along the whole external rotative surface of the joint and are not in the same direction as water flow, so that the water flow can be blocked effectively, and the sealing effect is further improved. When the fusion splicing ribs are arranged on the joint, the water tank can operate normally so long as one fusion splicing rib can block the water flow.

The utility model content

The utility model provides a kind of water tank, and it has overcome the existing deficiency of background technology.The technical scheme that its technical problem that solves the utility model adopts is:

A kind of water tank comprises body and joint, and this body is provided with opening, and the outer surface of revolution of this joint is provided with at least one welding rib, and the opening of this welding rib and this body is welded together.

Among one preferred embodiment: this welding rib surface of revolution outside the whole circle of this joint arranges continuously.

Among one preferred embodiment: this welding rib undulate shape.

The technical program is compared with background technology, and it has following advantage:

1. the opening of this welding rib and this body is welded together and forms an inseparable integral body, does not have the gap between this joint and this body, and sealing effectiveness is fairly good, does not have leakage problems.In addition, the opening of this welding rib and this body is welded together, and this joint and this body form an indivisible integral body, and this joint is connected quite firm with this body, and this joint is not easy to come off.

2. this joint and this idiosome are welded together, do not need other manufacturing procedure, reduce the labour, greatly reduced cost of production.

3. this welding rib surface of revolution outside the whole circle of this joint arranges continuously, this welding rib not with water (flow) direction in the same way, can effectively block current, further improve sealing effectiveness, and this joint and this body be connected firmly.When some welding ribs was set on this joint, as long as there is a welding rib can block current, this water tank just can operate as normal.

The specific embodiment

Please refer to Fig. 3, a kind of water tank 20 of the present utility model comprises a body 21 and a joint 22.This body 21 is provided with an opening 211.

Please refer to Fig. 4, this joint 22 is rotary structure.This joint 22 comprises that one inserts section 221 and one linkage section 222, and this insertion section 221 is connected the top of this linkage section 222.The outer surface of revolution of this joint 22 is provided with some welding ribs 223, and described these welding ribs 223 are positioned at this insertion section 221 parts.This welding rib 223 is vertical with the centre of gyration axis of this joint 22, and this welding rib 223 surface of revolution outside the whole circle of this joint 22 arranges continuously.

Please refer to Fig. 5, the insertion section 221 of this joint 22 is inserted in the opening 211 of this body 21.Described these welding ribs 223 are welded together with the opening 211 of this body 21.

Please refer to Fig. 5, Fig. 6 and Fig. 7, the opening 211 of described these welding ribs 223 and this body 21 is welded together and is achieved in that

At first, extruder is extruded the stock 23 of fusion, and this stock 23 is hollow tubular structure.This stock 23 is able to the degree of welding when extruding;

Then, this joint 22 is heated, make this welding rib 223 reach molten condition, again this joint 22 is placed this stock 23 inside, this insertion section 221 is inserted in this stock 23, close die 30, and this mould 30 is pressed together this stock 23 with this joint 22, this stock 23 is given this welding rib 223 with thermal energy transfer, and this stock 23 is welded together with this welding rib 223;

Then, these stock 23 inside are charged into gas, this stock 23 increases the structure that the die cavity that is adjacent to this blow mold 30 forms this body 21 in the pressure action lower volume of gas, and this stock 23 forms this opening 211 around the part of this joint 22, and this welding rib 223 is welded together with this opening 211.

At last, the semiproduct after the blow molding are carried out deburring, rim charge 24 is got rid of (as shown in Figure 7), just obtain water tank 20 of the present utility model.

Be appreciated that ground, also can omit separately this joint 22 is heated, make this welding rib 223 reach this step of molten condition, because this mould 30 is pressed together this stock 23 with this joint 22 after, these stock 23 heats own can pass to this welding rib 223, make this welding rib 223 softening states that reach welding, and this welding rib 223 is welded together with this stock 23.

In addition, these stock 23 inside are being charged into gas, this stock 23 increases in the step of structure that the die cavity that is adjacent to this blow mold 30 forms this body 21 in the pressure action lower volume of gas, also this joint 12 can be blocked, inflate this stock 23 at other positions at this stock 23, can reach the purpose that this stock 23 is carried out blow molding equally.

And, might not be to inflate this stock 23 to make these stock 23 volumes increase the die cavity that is adjacent to this mould 30, also can the die cavity of this mould 30 be vacuumized, thereby make the pressure of die cavity of this mould 30 less than the pressure of these stock 23 inside, in this case, this stock 23 can be adjacent to the die cavity of this blow mold 30 equally automatically.

In addition, this stock 23 might not be hollow tubular structure, please refer to Fig. 8, this stock 23a includes two monolithic body 231, the insertion section 221 of this joint 22 places between these two monolithic body 231, after the close die 30, this two monolithic body 231 is welded together the structure that can form this body 21 equally.

Please refer to Fig. 9 to Figure 12, be appreciated that ground, the shape of this welding rib 223, quantity and unrestricted, this welding rib 223 can be that the undulate shape arranges (as shown in Figure 9), this welding rib 223 also can be obliquely installed (as shown in figure 10), simultaneously, this welding rib can also be to arrange discontinuously.In addition, this joint 22 also can be the revolving body of other shapes, as J-shaped shape (as Figure 11, shown in Figure 12).

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
