Description

Technical Field

[0001] The utility model specifically relates to an ignition gun. Background Art

[0002] The structure of a traditional ignition gun generally includes a gun barrel and a gun head. A fuel tank is arranged in the gun barrel, a flame nozzle is arranged on the gun head, a feed pipe is connected between the fuel tank and the flame nozzle, and a switch is controlled to connect the fuel to the flame nozzle through the feed pipe. The flame nozzle is ignited by sparks after ignition, and the ignition action is realized. Among them, the fuel tank generally stores gasoline, liquefied gas, etc., which is prone to leakage and unsafe use during use.

[0003] With the maturity of the technology of ignition guns, ignition guns that use electric heat ignition heads instead of fuel ignition have gradually appeared on the market. The electric heat ignition gun, especially the arc ignition gun, usually includes a gun barrel and a gun head. The gun head is provided with a fire outlet, and an arc generating head is installed at the fire outlet. In order to protect the arc generating head, the arc generating head can generally be retracted into the gun barrel. When in use, the arc generating head needs to be pushed out first, and then ignited by pressing a button. In order to ensure safety, general ignition guns are equipped with a safety lock. For example, Chinese patent CN206540176 U discloses an arc ignition gun with a push key locking structure, which uses a tilting rod assembly to position the push key, so that the push key cannot be easily pushed, which has a safe and reliable effect.

[0004] However, currently the push key is locked and needs to be unlocked when in use. The limit locking structure of the push key is relatively complex and prone to failure. Once the locking structure of the push key fails, the push key may become unusable, thereby causing the entire product to become unusable. At the same time, the complex locking structure may also make the installation steps cumbersome, affecting assembly efficiency. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] The utility model provides an ignition gun, which comprises:

[0033] The housing 1 has a hollow passage, and a mounting tube 2 is provided at one end thereof, wherein the mounting tube is detachably arranged at one end of the housing, and the detachable arrangement simplifies the assembly difficulty;

[0034] The lower bracket 5 has a slide groove 54 on one side thereof that matches the upper bracket. The lower bracket 5 is U-shaped as a whole, and its outer surface is adapted to the shell and can be assembled in the hollow channel of the shell.

[0035] An upper bracket 4, one end of which is provided with an arc generating head 6, and a cavity for accommodating an ignition control mechanism is formed between the upper bracket and the lower bracket, the arc generating head is electrically connected to the ignition control mechanism, the upper bracket is partially placed in the slide groove and can slide relatively, and the upper bracket has a first position for accommodating the arc generating head in the mounting tube and a second position for extending the arc generating head out of the mounting tube;

[0036] The locking bracket 7 spans across the upper side of the lower bracket and forms a channel with the slide groove for the upper bracket to slide. The locking bracket is provided with a push button 3 which can be perpendicular to the sliding direction of the upper bracket. The locking bracket is bridge-shaped, and its upper surface is adapted to the inner wall of the shell. The channel can allow the upper bracket to slide without interfering with it, so that the upper bracket can slide relatively, and the push button is used to limit the sliding direction, thereby limiting the extension of the arc generating head.

[0037] A guide groove 41 is provided on the upper surface of the upper bracket, a limit groove 42 is provided on one side of the guide groove, and a guide block 31 is provided at the bottom of the push button. The guide block has a first state of being placed in the limit groove to limit the sliding of the upper bracket and a second state of being placed in the guide groove to release the limit on the upper bracket.

[0038] By moving the push button, the guide block at the bottom of the push button can slide from the guide groove into the limit groove or from the limit groove into the guide groove, thereby realizing the switching between the two states.

[0039] Positioning grooves 51 are provided on both sides of the lower bracket, and both ends of the locking bracket are embedded in the positioning grooves. The two sides of the locking bracket are embedded in the positioning grooves, and the locking bracket is restricted from moving along the sliding direction by the positioning grooves. At the same time, the locking bracket and the lower bracket form a whole, so that the push button has a locking function.

[0040] A positioning hole 52 is provided at the bottom of the positioning groove, and positioning blocks 71 adapted to the positioning holes are provided at both ends of the locking bracket. The positioning block bracket is inserted into the positioning hole, so that the cooperation between the two is more reliable.

[0041] The surface of the locking bracket 7 is provided with a transverse groove 72, and the bottom of the push button passes through the transverse groove and is placed in the guide groove. The push button can slide along the direction of the transverse groove to switch the state. At the same time, the design of the transverse groove limits the maximum stroke of the push button, and by providing a buckle at the bottom of the push button, it is connected with the locking bracket, not easy to fall off, and easy to install.

[0042] A gear slot 73 is provided on the side wall of the transverse slot, and a gear block is provided at the position where the push button cooperates with it. The gear block cooperates with the gear slot to realize the indication of two states, which is convenient for the user to perceive whether the switch is in place and avoid the phenomenon of structural damage caused by brute force operation when the switch is not in place.

[0043] An elastic member for resetting the upper bracket is arranged between the upper bracket and the bottom of the shell. The elastic member is a tension spring, which provides a force to pull the upper bracket back into the shell.

[0044] The two sides of the bottom of the upper bracket extend outward to form a first limit block 43, and the lower bracket is provided with a second limit block 53 in front of the movement of the first limit block. The first limit block cooperates with the second limit block to achieve the limitation of the maximum extension position. At the same time, the second limit block can also be directly composed of a locking bracket.

[0045] The upper bracket is located in front of the locking bracket and extends outward on both sides to form a third limit block 44, and the third limit block cooperates with the front end of the positioning groove on the lower bracket to limit the upper bracket to the maximum retracted position. It can also be directly limited by the locking bracket.

[0046] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
