Abstract

The utility model relates to the field of hydroelectric tools and in particular relates to a silica gel gun. The silica gel gun with an extrusion sleeve comprises a handle, a gun rack, a trigger and a push rod, wherein the handle is fixedly connected with the gun rack; the push rod passes through the handle and forms a sliding pair with the gun rack; a wedge-shaped propelling rack is arranged in the axial direction of the push rod; the trigger is hinged on the handle via a fulcrum; a driving pawl is hinged at the top end of the trigger; a limiting pawl is also hinged in the handle; the extrusion sleeve is a circular truncated cone; a blocking piece is arranged in the extrusion sleeve; one side of the blocking piece is hinged on the inner wall of the extrusion sleeve via an axis of rotation; an elastic reset mechanism is installed on the blocking piece. The silica gel gun has the beneficial effects that as the extrusion sleeve is connected at the front end of the gun rack, when a part of a silica gel barrel is used and the residual silica gel needs to be stored, the blocking piece in the extrusion sleeve can automatically reset to seal the opening, so that the residual silica gel can not be solidified due to contact with the air, thus avoiding waste of the residual silica gel.

Description

Band is extruded the silica gel gun of cover

Technical field

The utility model relates to water power field of tool, relates in particular to a kind of silica gel gun.

Background technology

Silica gel is a kind of material for sealing, and is widely used in industrial production.Taste prevent silica gel contact with air and occur solidify, conventionally silica gel is stored in silica gel cylinder.The size shape of silica gel cylinder is standardization at present, and it is shaped as the cylindrical shell of a sealing, and cylindrical shell head has a through hole, cylindrical shell afterbody is provided with a movably end cap, in use, promote the end cap of cylindrical shell afterbody, the silica gel in cylindrical shell can be squeezed out by the through hole of cylindrical shell head.

In prior art 200920068189.2, disclose a kind of conventional silica gel gun, and set up cleansing pin on this conventional silica gel gun, to solve behind silica gel cylinder Kaifeng, the silica gel in it is the dry defect that cannot extrude easily.But this settling mode in Baosteel patent is more passive, fundamentally do not solve the curing problem of silica gel, because silica gel is opened after exposure, be not only often that surperficial one deck solidifies, but can be because ventilative reason causes scrapping of whole cylinder residue silica gel.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of band extrudes the silica gel gun of cover, this silica gel gun has connected one at the front end of gun rack and has extruded cover, when silica gel cylinder has used a part, need to be by residue when preservation in silica, can automatically reset mouth is sealed extruding catch in cover, remaining like this silica gel can not solidify because air contact produces, and has avoided the waste of residue silica gel.

The utility model is achieved in that a kind of band extrudes the silica gel gun of cover, comprise handle, gun rack, trigger and push rod, described handle and gun rack are fixedly linked, described push rod forms sliding pair through handle and gun rack, in the axial direction of described push rod, be provided with the propelling tooth bar of a wedge shape, described trigger is hinged on handle by fulcrum shaft, the top of trigger is hinged with driving pawl, in described handle, be also hinged with position-limited claw, the crown of described propelling tooth bar points to the front end of gun rack, described driving pawl and position-limited claw match with propelling tooth bar, the front end of described gun rack by connection cord with extrude cover be connected, the described cover of extruding is for truncated cone-shaped, extrude and in cover, be provided with catch, one side of described catch is hinged on by rotating shaft on the inwall of extruding cover, flexible restoring organ is housed on catch.

Described flexible restoring organ is torsion spring, and described torsion spring set is contained in rotating shaft.

The rear end of described push rod is bent to regulating handle.

On described handle, also offer lightening hole.

The front end of described gun rack is the supporting disk of U-shaped.

The axis of described push rod is parallel with the axis of gun rack.

The silica gel gun that the utility model band is extruded cover has connected one at the front end of gun rack and has extruded cover, when silica gel cylinder has used a part, need to be by residue when preservation in silica, can automatically reset mouth is sealed extruding catch in cover, remaining like this silica gel can not solidify because air contact produces, and has avoided the waste of residue silica gel.

Brief description of the drawings

Fig. 1 is that the master that the utility model band is extruded the silica gel gun of cover looks perspective diagram;

Fig. 2 is the internal structure schematic diagram of extruding cover in the utility model.

In figure: 1 handle, 2 gun racks, 3 triggers, 4 push rods, 5 advance tooth bar, 6 lightening holes, 7 fulcrum shafts, 8 driving pawls, 9 to extrude cover, 10 position-limited claws, 11 suckers, 12 regulating handles, 13 catch, 14 rotating shafts, 15 torsion springs.

Detailed description of the invention

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.

Embodiment 1

As shown in Figure 1, a kind of band is extruded the silica gel gun of cover, comprise handle 1, gun rack 2, trigger 3, push rod 4 overlaps 9 with extruding, described handle 1 is fixedly linked with gun rack 2, described push rod 4 forms sliding pair through handle 1 and gun rack 2, in the axial direction of described push rod 4, be provided with the propelling tooth bar 5 of a wedge shape, described trigger 3 is hinged on handle 1 by fulcrum shaft 7, on fulcrum shaft 7 and two jointed shafts, be all provided with reduction torsion spring, the top of trigger 3 is hinged with driving pawl 8, in described handle 1, be also hinged with position-limited claw 10, the crown of described propelling tooth bar 5 points to the front end of gun rack 2, described driving pawl 8 and position-limited claw 10 match with advancing tooth bar 5, make to advance tooth bar 5 engage or throw off with driving pawl 8 by rotating push-rod 4, the front end of described gun rack 2 by connection cord with extrude cover and 9 be connected, described in extrude cover 9 for truncated cone-shaped, extrude in cover 9 and be provided with catch 13, a side of described catch 13 is hinged on and is extruded on the inwall that overlaps 9 by rotating shaft 14, on catch 13, flexible restoring organ is housed.

As shown in Figure 2, in the present embodiment, described flexible restoring organ is torsion spring 15, and described torsion spring 15 is sleeved in rotating shaft 14; Before using, will extrude cover 9 and be sleeved on silica gel cylinder head, advance tooth bar 5 to engage with driving pawl 8, cocking makes push rod 4 forward end motions, when thrust acquires a certain degree, silica gel backs down catch 13 is extruded silica gel, after operation completes, thrust deficiency, catch 13 resets under the effect of torsion spring, realize sealing to silica gel cylinder, only otherwise will extrude cover 9 and take off, remaining silica gel just can not contact with air curing, extrude one end settings that cover 9 is connected with silica gel cylinder and there is certain flexible elastic tape, with the effect of guaranteeing to seal.

In the present embodiment, for rotating push-rod 4 easily, the rear end of described push rod 4 is bent to regulating handle 12.

In addition, because silica gel gun itself is not very high to the requirement of intensity, and for the ease of the grasping of staff, it is very large that handle 1 can do again, will increase like this weight of silica gel gun itself, so in the present embodiment, on described handle 1, also offer lightening hole 6, can save material like this, can reduce again the weight of silica gel gun, easy to use.

For being placed on silica gel gun of making that silica gel cylinder can be more firm, the supporting disk that the front end of described gun rack 2 is U-shaped.
