Description

Inflatable foaming plug

Technical Field

The utility model relates to a solar water heater production auxiliary assembly, specifically speaking relates to an inflatable foaming stopper.

Background

Among the prior art, the water tank mouth of pipe foaming mould of vacuum tube formula solar water heater uses single foaming stopper, during the foaming, need fill in the water tank mouth of pipe one by the foaming stopper, the foaming is accomplished the back, pull out the foaming stopper in turn, not only production efficiency is very low, moreover, because the external diameter of foaming stopper is close to the orificial internal diameter of water tank, it is more time-consuming when filling in and pulling out, hard, and simultaneously, there is certain clearance between foaming stopper and the water tank mouth of pipe inner wall, during the foaming, the material leakage phenomenon can appear, lead to the water tank mouth of pipe more rough.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an inflatable foaming stopper solves above technical problem.

In order to solve the above problems, the utility model adopts the following technical scheme:

an inflatable foaming plug is characterized in that: the foaming plug comprises a foaming plug main body with a hollow interior, an expansion head positioned at the front end of the foaming plug main body and a fixed seat assembled at the tail end of the foaming plug main body; the front part of the foaming plug main body is of a tapered structure with a thin front part and a thick rear part; the expansion head and the foaming plug main body are of an integral structure, the outer diameter of the expansion head is smaller than that of the front end of the foaming plug main body in a non-inflation state, and the outer diameter of the expansion head is larger than that of the tail part of the foaming plug main body in an inflation state; the fixing seat is provided with an inflation hole, an inflation channel is arranged in the fixing seat, and the inflation hole is communicated with the inner cavity of the foaming plug main body through the inflation channel.

Preferably, the front end of the fixing seat is inserted into the tail port of the foaming plug main body, and a fastening buckle for locking and fixing the tail end of the foaming plug main body and the fixing seat is arranged outside the tail end of the foaming plug main body.

Has the advantages that: compared with the prior art, the inflatable foaming plug has the advantages that when the inflatable foaming plug is not inflated, the outer diameter of the expansion head is smaller, the inflatable foaming plug can be easily plugged into and pulled out of a water tank pipe orifice, and time and labor are saved; after the inflatable foaming plug is inserted into the pipe orifice of the water tank, the expansion head extends into the water tank from the pipe orifice of the water tank, before foaming, the inflatable foaming plug is inflated, the expansion head expands and becomes large, the pipe orifice of the water tank is tightly sealed, no material leakage occurs, and the cleanness and the smoothness of the pipe orifice of the water tank are ensured; simultaneously, arrange a plurality of inflatable foaming stopper parallel and install on supporting mechanism, during the foaming, can once only fill in each inflatable foaming stopper simultaneously in each mouth of pipe of whole water tank, after the foaming is accomplished, extract each inflatable foaming stopper from the mouth of pipe of water tank simultaneously again to can improve production efficiency greatly.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Example 1:

referring to fig. 1 and 2, the inflatable foaming plug of the present embodiment includes a hollow foaming plug body 2, an expansion head 1 located at the front end of the foaming plug body 2, and a fixing seat 4 assembled at the rear end of the foaming plug body 2.

The front part of the foaming plug main body 2 is of a tapered structure with a thin front part and a thick rear part; the expansion head 1 and the foaming plug main body 2 are of an integral structure, and in a non-inflation state, the outer diameter of the expansion head 1 is smaller than that of the front end of the foaming plug main body 2, as shown in figure 1; in the inflated state, the outer diameter of the expansion head 1 is larger than the outer diameter of the tail part of the foaming plug body 2, as shown in fig. 2. The fixing seat 4 is provided with an inflation hole 5, an inflation channel 6 is arranged in the fixing seat 4, and the inflation hole 5 is communicated with the inner cavity of the foaming plug main body 2 through the inflation channel 6.

The front end of the fixing seat 4 is inserted into the tail port of the foaming plug main body 2, and a fastening buckle 3 for locking and fixing the tail end of the foaming plug main body 2 and the fixing seat 4 is arranged outside the tail end of the foaming plug main body 2.

When the inflatable foaming plug is not inflated, the outer diameter of the expansion head 1 is smaller, and the inflatable foaming plug can be easily plugged into and pulled out of a water tank pipe orifice, so that time and labor are saved; after the inflatable foaming plug is inserted into the pipe orifice of the water tank, the expansion head 1 extends into the water tank from the pipe orifice of the water tank, before foaming, the inflatable foaming plug is inflated, the expansion head 1 expands and becomes large, the pipe orifice of the water tank is sealed tightly, no material leakage occurs, and the cleanness and the smoothness of the pipe orifice of the water tank are ensured; simultaneously, arrange a plurality of inflatable foaming stopper parallel and install on supporting mechanism, during the foaming, can once only fill in each inflatable foaming stopper simultaneously in each mouth of pipe of whole water tank, after the foaming is accomplished, extract each inflatable foaming stopper from the mouth of pipe of water tank simultaneously again to can improve production efficiency greatly.

Example 2:

as shown in fig. 3 and 4, the inflatable foaming plug of the present embodiment is different from the embodiments in that: the afterbody of expansion head 1 and foaming stopper main part 2 is longer, and the length that fixing base 4 stretched into in the 2 afterbody inner chambers of foaming stopper main part is longer, simultaneously, does not set up fastening buckle 3 in the tail end outside of foaming stopper main part 2.

The working principle of the inflatable foaming plug of the embodiment is the same as that of the embodiment 1, and the detailed description is omitted.

The above is only the embodiment of the present invention, not so limit on the other hand through the patent scope of the present invention, all utilize the equivalent structure made in the specification and the attached drawings, directly or indirectly apply to other related technical fields, all with the same principle within the patent protection scope of the present invention.
