Abstract

The utility model discloses a connecting base for a polyurethane foam caulking agent spray gun. The connecting base comprises a hollow threaded base and a protective cover, wherein an external thread is arranged on the outer surface of the base; the bottom of the base extends outwards to form a limiting plate; and the protective cover is arranged in a clamp slot at the top of the base via a jaw. In the technical scheme, the protective cover is connected to the clamp slot inside the top end of the base by the jaw and is firmly fixed on the base; and when the connecting base is used, the base is connected to the tank body with the help of pressure equipment, and the jaw of the protective cover is separated from the base under the action of pressure and is clamped on the clamp slot of the base through extrusion so as to achieve the aims of protection of the valve during storage and transport and convenience in opening during use.

Description

A kind of cranny filler of polyurethane foam spray gun is used Connection Block

Technical field

The utility model relates to cranny filler of polyurethane foam with spray glue technical equipment field, and especially a kind of cranny filler of polyurethane foam spray gun is used Connection Block.

Background technology

It is two independent products that traditional cranny filler of polyurethane foam uses the base and the over cap of spray glue Connection Block, is fixed to through over cap and accomplishes on the base using after the assembling of protecting seat.In traditional Connection Block, the operation that production and assembling need is more, and shared material resources and manpower are big, and the finished product production cycle is long, and product more scabrous weld mark of existence and pneumatosis defective, and percent defective is higher.

Summary of the invention

In order to remedy long and production cost height and the high deficiency of percent defective of above-mentioned Connection Block production cycle when producing, the utility model proposes a kind of cranny filler of polyurethane foam and uses Connection Block.

Its technical scheme does, comprises the threaded base and the over cap of hollow, and base outer surface is provided with external screw thread, outwards extends and form limiting plate in the base bottom, and over cap is fixed on the draw-in groove of base top through claw.In the present technique scheme; Over cap adopts claw to be arranged on the inner draw-in groove in base top, and four claws with the materials flow water conservancy diversion, make its mean allocation in injection moulding; Improve weld mark and pneumatosis defective that traditional Connection Block causes because of materials flow is irregular, improve the effect of product combination property.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the enlarged diagram of A position among Fig. 1 embodiment;

Wherein, 1, threaded base; 11, draw-in groove; 2, over cap; 21, claw; 3, limiting plate.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

With reference to Fig. 1, a kind of embodiment of the utility model.A kind of cranny filler of polyurethane foam comprises the threaded base 1 and over cap 2 of hollow with spray glue Connection Block, and base outer surface is provided with external screw thread, outwards extends and form limiting plate 3 in the base bottom, and over cap is set on the draw-in groove 11 of base top through claw 21.The over cap of present embodiment was fixed to the base bottom on the storage tank in when transportation, and limiting plate contacts with tank body tightly, and claw is accomplished the assembling of over cap, Connection Block and tank body by compressing into base simultaneously, the safety of over cap protection valve.In use, Connection Block is screwed to spray gun with external screw thread, spray gun uses valve open then.Adopt the Connection Block of this mode, over cap adopts claw to be connected on the inner draw-in groove in base top, and over cap is fixed on the base, and the protection valve is opened during use conveniently when storing and transporting.

In conjunction with Fig. 2, a kind of connected mode of claw and draw-in groove, the movable pressure of claw is stuck on the draw-in groove.

In sum, more than being merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims

1. a cranny filler of polyurethane foam spray gun is used Connection Block; Comprise the threaded base (1) and the over cap (2) of hollow, it is characterized in that base outer surface is provided with external screw thread; Outwards extend and form limiting plate (3) in the bottom, over cap is set on the draw-in groove (11) of base top through claw (21).
