Description
Technical field
The utility model relates to a kind of foam gun, relates in particular to a kind of device that can regulate the flow of expanding foam solution in the foam gun.
Background technology
Expanding foam solution architectural be to be used for the slit is coated with solid material, it need spray by foam gun being to be stored in the receiver by spraying as last.The structure of foam gun comprises rifle body, gun barrel, shank, spanner, and gun barrel is threaded on the rifle body, and shank is located in the gun barrel and is had an end to stretch out gun barrel and links with the spanner that is hinged on the rifle body.For the flow to expanding foam solution is regulated, on the rifle body, also be provided with the flow regulator of an expanding foam solution, the external part of this flow regulator and described shank links.The structure of the flow regulator of expanding foam solution comprises that one is threaded in the set screw on the rifle body, and the outside of rifle body is stretched out in the outer end of this set screw, and its inner roof pressure has a compression spring, and the elastic force of this compression spring acts on the external part of shank.Can regulate regulating the space by the turn set screw, thereby reach the change of distance when shank endwisely slips when pulling spanner in gun barrel, and then reach the purpose of regulating the expanding foam solution flow.The flow regulator of this expanding foam solution has certain defective, at first, because the elastic force of compression spring acts directly on the inner of set screw, seems gruelling during the turn set screw.The compression spring can be to direct roof pressure on the inner face of set screw, also can between set screw inner face and compression spring, install a pad additional, in the time of on compressing the inner face of the direct roof pressure of spring in set screw, by the effect of frictional force, it is painstaking that the turn set screw more seems.Secondly, set screw is after the position on the rifle body is fixed, and different operators is when the operation foam gun, and the flow of expanding foam solution is unfixed.This is because the strength of different operating person finger is inequality, points the bigger operator of strength and can increase the decrement of compression spring when the operation foam gun, thereby also just make the flow of expanding foam solution become big.Otherwise, point the little operator of strength when the operation foam gun, the flow of expanding foam solution is just little.Like this, be difficult for the flow of expanding foam solution is regulated.
Summary of the invention
Be the above-mentioned defective that the expanding foam solution flow regulator that overcomes on the existing foam gun is had, the utility model technical issues that need to address are: a kind of foam gun expanding foam solution flow regulator light, that the expanding foam solution flow is easily accurately regulated of regulating is provided.
For solveing the technical problem, the technical solution of the utility model: a kind of foam gun expanding foam solution flow regulator, described foam gun comprises rifle body, gun barrel, compression spring, shank, spanner, this adjusting device is located on the rifle body of foam gun, comprise a set screw of stretching out the external side of rifle, it is characterized in that, described compression spring housing is connected on the shank, and be positioned at gun barrel, one end acts on the shank, the other end acts on the rifle body, and an end of shank stretches out the outside of rifle body and is connected on the spanner; The axial sliding cavity that is provided with of described rifle body upper edge shank, be provided with an adjusting screw(rod) slidably in the sliding cavity, the threaded one end of this adjusting screw(rod) is connected on the set screw, and the other end is circumferentially fixing with respect to sliding cavity, set screw can be rotated, and with respect to the rifle axon to fixing.Spanner is hinged on the rifle body, and the external part and the spanner of shank link, and pulls spanner and can drive shank and slide towards the external part direction of shank in gun barrel, unclamp spanner after, under the effect of compression spring, shank slides towards opposite direction.The turn set screw can make adjusting screw(rod) slide in sliding cavity, behind the set screw location, distance between adjusting screw(rod) and the shank also just determined, this distance is the ultimate range of shank when endwisely slipping in gun barrel, thereby the flow of expanding foam solution has also just obtained definite in the foam gun.
As preferably, the cross section of described sliding cavity is a polygon, and the shape of the other end of described adjusting screw(rod) and the shape of sliding cavity match.Be matched in clearance between adjusting screw(rod) and the sliding cavity, adjusting screw(rod) both can slide in sliding cavity, also can maintain a fixed, and this provides convenience for the slip that set screw drives adjusting screw(rod).
As preferably, the external part of described shank is provided with a limited block, and this limited block is fixedly connected on the shank.After the external part of shank passes hole set on the spanner with gap, be provided with a limited block that diameter is relatively large more thereon, spanner can drive shank by this limited block and slide.
As preferably, be provided with a positioning sleeve between described set screw and the rifle body, positioning sleeve is fixedly connected on the rifle body, and is socketed in the periphery of set screw with gap.Set screw is generally stepped, and positioning sleeve is socketed in the thin end of set screw, and positioning sleeve is generally by being threaded on the rifle body.
As preferably, the outside of positioning sleeve is stretched out in the inner of described set screw, is provided with jump ring on the inner of set screw.This jump ring can make set screw carry out axial location with respect to positioning sleeve, and is easy to assembly.
Compare with existing common foam gun, the utlity model has following beneficial effect:
1, the elastic force owing to compression spring in the foam gun does not act on the set screw, seems light, quick when the turn set screw.
2, be to determine owing to carry out timing at flow by the distance of adjusting between adjusting screw(rod) and the shank external part to the foam gun expanding foam solution, after one amount distance between the two is determined, the distance that shank slides in gun barrel just has been determined time, and can not change, can regulate exactly the flow of foam gun expanding foam solution like this, when even different operators operates foam gun, the flow of expanding foam solution also can be consistent.
3, because spiral helicine compression spring is located in the gun barrel, and expanding foam solution can be obtained stirring when flowing through the compression spring, the good uniformity of expanding foam solution helps improving foaming effect.
