Description

Gas spray gun

Technical field

The utility model relates to the electronic ignition mechanism of Gas spray gun of a kind of Gas spray gun, particularly a kind of interchangeable working head and the improvement of gas jar fitting sleeve.

Background technology

China's utility model 99216757.4 patents, mainly form by working head, T shape pipe, Air-regulating valves, shell, fitting sleeve, this Gas spray gun is when work, can change working head according to the job of reality, but because its sparking mode is also relatively backward, do not adopt these means conveniently of electronic ignition, the body of a gun structural design of itself also is not suitable for installing the igniting lock simultaneously, therefore the user must take gas jar one hand-held igniter Gas spray gun could be lighted on the other hand, cause inconvenience in practical operation, influence operating efficiency.

China's utility model 98209815.4 patents, the coupling part of its Gas spray gun and gas jar is a fitting sleeve, this fitting sleeve is adopted an adapter, a ring seat, two trunnions and the two urgent pieces that support and is combined.In when combination, two compel to support the relative Cheng Yuan of piece stretches with the pivot ear and places the ring seat groove, place tip hole with trunnion and link, and make the ring seat cover thread segment of pipe that is spirally connected, and the pipeline section of taking over the tool scalene cone is stretched and is butted on two inner edge surfaces of compeling to support the oblique terrace of piece tool; Two urgent stretching to piece place in the gas jar tank deck ring wall thus, be butted on the permanent intrados of ring with its outer ring surface concave arc, and gas jar escape pipe is inserted and is embedded in the adapter guide hole, the relative spiral shell with ring seat of multiple connection pipe advances, the one suitable aeration status that compresses escape pipe formation driving fit, second the scalene cone by the adapter lower tube section pushes against the two oblique terraces of compeling to the piece inner edge surface, and suitable support two urgent being closely against to the piece expansion are encircled permanent fixing.Because this connector cover structure is too complicated, produce the each several part part of this fitting sleeve and it be assembled into whole connector cover not only time-consuming but also take a lot of work; And the adapter of this fitting sleeve does not prevent the safety device that both separate with the threaded portion that ring seat cooperates, and screw thread is very easily stubborn excessive when both unclamp relatively, causes taking over and separates with ring seat, increases the inconvenience of work on foot.

Summary of the invention

The purpose of this utility model is the improvement to a kind of electronic ignition mechanism of Gas spray gun of interchangeable working head and gas jar fitting sleeve, wherein Gas spray gun is on the basis that keeps original interchangeable working head, in Gas spray gun, added the igniting lock and and working head between be electrically connected mechanism, user's cocking just can be lighted spray gun, make the operation of Gas spray gun lightly convenient, igniting is convenient.

Another purpose of the present utility model is the improvement to a kind of electronic ignition mechanism of Gas spray gun of interchangeable working head and gas jar fitting sleeve, this fitting sleeve parts that are formed in one, break away from the loaded down with trivial details operation and the cost of isolation of components production and assembling, also be provided with block in the block set, reverse turn is exaggerated when preventing because of replacing gas jar, causes cap bag and block set to break away from accidentally.

For achieving the above object, the utility model adopts following technical scheme: cooperate the cavity place that forms that one igniting lock is set with shell at T shape pipe, and on the lead of igniting lock, wrap insulating materials, this lead forms a contact exposing housing parts, simultaneously the corresponding aforementioned contact of an end at working head also is provided with a contact, and relies on lead to cause front end, when working head is fixed on T shape pipe when going up, directly contact keeps being electrically connected of lead between two contacts.

T shape pipe of the present utility model is by a fitting sleeve gas jar to be connected the following of T shape pipe, fitting sleeve 7 is combined by a cap bag, a block set, wherein there is the adapter guide hole that can match with the escape pipe of gas jar cap bag inside, its inside is provided with sealing ring, and conduit and T shape pipe is set on cap bag is connected; Centre, block set upper end forms the hole that can hold cap bag, has screw thread and solid on the hole with the cap bag spiral shell, the vertical elasticity claw that is provided with the band inclined-plane more than two or two that extends of its lower ends downward, the elasticity claw outside has the ring-type projection, the projection external diameter is greater than the internal diameter of the scrobicular ring of gas jar, the position of the corresponding cap bag upper flange in hole is provided with in the screw opening travel block that can offset with flange.As long as grasp when the gas jar is installed block set toward the escape pipe one of gas jar buckle one by, elasticity claw on the block set just is stuck in the scrobicular ring of gas jar, gas jar escape pipe is inserted and is embedded in the adapter guide hole, as long as the relative spiral shell with cap bag of block set is advanced, just can compress the aeration status of escape pipe and T shape pipe formation driving fit, the gas jar just is fixed together with Gas spray gun simultaneously, its fitting sleeve is simple in structure, production and easy to assembly, also very convenient, quick with the installation of gas jar, and also closely firm to each other.

The igniting lock that the utility model adopted; and with the bindiny mechanism of working head, the trigger that can make the user only need pull the igniting lock just can be lighted gas, unclamps just to make flare extinguish; so not only convenient but also safety has the protection of the insulating materials lock leaky of can not lighting a fire simultaneously.And adopted the design of fitting sleeve, make the gas jar can be very convenient, correctly be installed on the Gas spray gun, very firm again, be unlikely to when work, to come off, can make the user only take the Gas spray gun main body to carry out work relievedly, do not worry the problem that the gas jar comes off at all, when changing the gas jar, can easily take off the gas jar once drawing, easily convenient, and also laborsaving.
