Abstract
The utility model discloses a rear cover of a pneumatic glue gun and belongs to the technical field of pneumatic glue guns. The rear cover of the pneumatic glue gun comprises a rear cover body, wherein an air exhaust hole is formed in the rear cover body, an air inlet joint connected with an air inlet pipe and a gun pipe joint connected with a glue pipe mounting pipe; the air inlet pipe is arranged inside the air inlet joint; an air outlet hole is formed in the gun pipe joint; an air exhaust screw cap is arranged on the air exhaust hole; a sealing rubber sheet is movably arranged at the bottom of the air exhaust screw cap; and the air outlet end of the air inlet pipe is communicated with any one of the air exhaust hole or the air outlet hole. By the rear cover of the pneumatic glue gun, when an air supply supplies air, the sealing rubber sheet jacks the air exhaust screw cap up; the air can directly enter the glue pipe mounting pipe through the air outlet hole, so that power for realizing glue outflowing of a thrust glue pipe is formed; when the air supply does not supply the air, the sealing rubber sheet downwards blocks an air outlet of the air inlet pipe under the air pressure in the glue pipe mounting pipe; the air in the glue pipe mounting pipe is exhausted through the air exhaust hole; due to a muffler, noise produced by air exhaust is avoided; and the rear cover is simple in structure, high in safety, convenient to operate and suitable for popularization and application.
Description
Technical field
The utility model belongs to the Pneumatic glue gun technical field, is specifically related to a kind of simple in structure, easy to operate, Pneumatic glue gun bonnet that security performance is good be used to being arranged on Pneumatic glue gun.
Background technology
The glue rifle is a kind of instrument of playing glue or plastic squeeze, needs the place of applying glue just might use, and is widely used in building decoration, electronic apparatus, Pneumatic glue gun automobile and automobile component, the industries such as boats and ships and container.Pneumatic glue gun is that dependence compressed air is power, goes to promote the bottom of glue, and more manual glue rifle can alleviate operator's labour intensity, the quality of increasing work efficiency and playing glue.The Pneumatic glue gun that uses at present is directly to connect source of the gas, the operation site air pressure of general plant source is the 6-8 kilogram, Pneumatic glue gun is that the 6-8 kilogram can work certainly at air pressure, if source of the gas air pressure is too low, may have influence on the normal operation of Pneumatic glue gun, cause dozen glue speed slow, even not show the problems such as glue, and wayward, there is potential safety hazard.
The utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of simple in structure, easy to operate, Pneumatic glue gun bonnet that security performance is good be used to being arranged on Pneumatic glue gun.
Described a kind of Pneumatic glue gun bonnet, comprise the bonnet body, it is characterized in that the inlet suction port that is equipped with steam vent on described bonnet body, is connected with air inlet pipe and the gun barrel joint that is connected with the sebific duct mounting pipe, be provided with air inlet pipe in described inlet suction port, be equipped with venthole on described gun barrel joint, be equipped with the exhaust nut on described steam vent, the activity of exhaust nut bottom arranges the caulking gum sheet, and the outlet side of described air inlet pipe communicates with any one in steam vent or venthole.
Described a kind of Pneumatic glue gun bonnet is characterized in that the silencer that described exhaust nut top is provided for eliminating the noise.
Above-mentioned a kind of Pneumatic glue gun bonnet, comprise the bonnet body, the inlet suction port that be equipped with steam vent on described bonnet body, is connected with air inlet pipe and the gun barrel joint that is connected with the sebific duct mounting pipe, be provided with air inlet pipe in inlet suction port, be equipped with venthole on the gun barrel joint, be equipped with the exhaust nut on steam vent, the activity of exhaust nut bottom arranges the caulking gum sheet, and the outlet side of described air inlet pipe communicates with any one in steam vent or venthole.The utility model is by adopting above-mentioned technology, and during gas source feed, the caulking gum sheet upwards withstands the exhaust nut, block steam vent and prevent that gas from outwards flowing out, directly entered in the sebific duct mounting pipe by steam vent by air inlet pipe, form power, work is carried out in the plastic emitting of thrust sebific duct; If not during air feed, the caulking gum sheet is blocked the gas outlet of air inlet pipe downwards under gas pressure in the sebific duct mounting pipe, the gas in the sebific duct mounting pipe is discharged by steam vent, produces noise when silencer being set preventing exhaust, it is simple in structure, easy to operate, security performance is high, is suitable for applying.
Description of drawings
Fig. 1 the utility model structural representation;
Fig. 2 is broken section structural representation of the present utility model.
In figure: 1-inlet suction port, 2-gun barrel joint, 3-steam vent, 4-air inlet pipe, 5-caulking gum sheet, 6-exhaust nut, 7-silencer, 8-venthole.
The specific embodiment
The utility model will be further described below in conjunction with Figure of description:
as shown in Fig. 1-2, a kind of Pneumatic glue gun bonnet, be used for being arranged on Pneumatic glue gun, it comprises the bonnet body, be equipped with steam vent 3 on described bonnet body, the inlet suction port 1 that is connected with air inlet pipe and the gun barrel joint 2 that is connected with the sebific duct mounting pipe, be provided with air inlet pipe 4 in described inlet suction port 1, be equipped with venthole 8 on described gun barrel joint 2, be equipped with exhaust nut 6 on described steam vent 3, the 6 bottom activities of exhaust nut arrange caulking gum sheet 5, the outlet side of described air inlet pipe 4 communicates with any one in steam vent 3 or venthole 8, the noise that produces during for fear of exhaust, the silencer 7 that described exhaust nut 6 tops are provided for eliminating the noise.
Use procedure of the present utility model is: after the Pneumatic glue gun bonnet is installed, during the work of Pneumatic glue pine, gas source feed is by air inlet pipe 4 air feed, upwards withstand exhaust nut 6 at aerodynamic force effect lower seal sheet rubber 5, block steam vent 3 and prevent that gas from outwards flowing out, gas is directly entered in the sebific duct mounting pipe by venthole 8 by air inlet pipe 4, forms power, and work is carried out in the plastic emitting of thrust sebific duct; When stopping air feed, movable downwards under the pressure of caulking gum sheet 5 residual gas in the sebific duct mounting pipe, block the gas outlet of air inlet pipe 4, residual gas in the sebific duct mounting pipe is discharged by steam vent 3, the noise that produces when preventing that a large amount of gases from discharging, the utility model arranges silencer on steam vent 3, Pneumatic glue gun rear cover structure of the present utility model is simple, easy to operate, security performance is high, is suitable for applying.
