Description

Water pistol with control water yield switch

Technical field

The utility model relates to a kind of water pistol technical field that can regulate and control water yield switch.

Background technology

Existing water pistol kind is a lot, if any its Granted publication of a Chinese patent is CN2368003Y, denomination of invention is the product of " water pistol with control water yield switch of improvement ", it comprises the rifle body, the control bolt, water-baffling sleeve and adjustment bolt, wherein the water channel of a three-stage shape is established in the handle inside of rifle body, in this three-stage shape water channel, the solid water-baffling sleeve of path scalariform place plug, inside is nested with one and is subjected to the control bolt that supports on the spring, the lever medial margin of rifle body is provided with a groove chamber in addition, on the groove bottom of this groove chamber, hypomere is convexly equipped with a scalariform post and a hollow cylinder respectively, be nested with one in this hollow cylinder and adjust bolt, and the conical surface of this adjustment bolt compresses the coniform head tip of control bolt, notch place in groove chamber on gun body articulates a trigger, this trigger is " Contraband " shape, pull the medial surface hypomere in the middle of it and be convexly equipped with a coniform supporting and pushing column against the terminal surface of adjusting bolt, the intermediate plate epimere is provided with the ccontaining breach of a button in addition, the lower edge of the ccontaining breach of this button is provided with one and supports the inclined-plane, intermediate plate medial surface and a groove is set to the inlay card groove again at the ccontaining breach downside of button, and the inner ccontaining button of the ccontaining breach of button, this button medial surface epimere is convexly equipped with a hollow sleeve pole, this hollow sleeve pole leans with the scalariform post upper spring that is nested with rifle body end chamber, be provided with in the button bottom side in addition and be the fine setting inclined-plane, with the ccontaining breach of button of trigger support the inclined-plane paste mutually to, and fine setting both sides, inclined-plane is respectively established elastic groove one, and between two elastic grooves, form a butted portion, the end of this butted portion is provided with a bit of horizontal segment in addition, and connect triangular shape guiding edge clipping, and button is borrowed in the ccontaining breach of button that this guiding edge clipping is installed in trigger, and the fine setting inclined-plane and the supporting part of the support plane of the ccontaining breach of button of trigger cooperation button.Certain advantage is we can say in this design; but its shortcoming is to occur blocking or malfunctioning through regular meeting between button and the trigger; the reason of blocking is: no matter trigger and button are being opened, are being opened big and closing in the process of current; trigger be in contact with one another all the time by button; make its elastic force can't reach requirement; one when meet some dusts as: sand or tiny impurity enter water pistol; make trigger and button increase friction; cause water pistol often to block and malfunctioning; these often make troubles to work; and its inner discharge is also on the low side, so await improving.

Summary of the invention

Technical problem to be solved in the utility model provides a kind ofly to be regulated and control the size of current or is closed by button or trigger, and can avoid trigger and button to block mutually and malfunctioning have a water pistol of controlling water yield switch.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this water pistol with control water yield switch comprises the rifle body, the control bolt, seal ring and adjustment bolt, be provided with the water channel of three-stage shape in the handle inside of rifle body, in this three-stage shape water channel, intrinsic seal ring is filled at the scalariform place on path rank, this seal ring inner via hole is equipped with and is subjected to the control bolt that supports on the volute spring, lever lateral margin at the rifle body is provided with the groove chamber, on the groove bottom of this groove chamber, hypomere is convexly equipped with scalariform post and hollow cylinder respectively, be nested with the adjustment bolt in this hollow cylinder, and the conical surface of this adjustment bolt compresses an end of control bolt, the notch place of groove chamber on gun body articulates trigger, in the breach of trigger epimere, be provided with button, it is characterized in that: there is the rail-like groove its upper surface of described button, this groove can be linked in together slidably relatively with rail-like raised line on the rifle body, contact-making surface at button bottom and trigger is domatic, and be shaped on the positioner of button and trigger on domatic, and on these button two sides, be respectively equipped with tack, this tack is fixed in recessed the groove on the trigger two sides, and can slide relatively along recessed groove.

As improvement, described positioner is to be positioned at the domatic zigzag panel that is provided with, and also can have little groove with the trigger place of matching at zigzag panel end, and described tack is fixed on the end bead that is positioned at the indoor button of groove two sides.

Improve again, the interlude of described its medial surface of trigger is provided with against the coniform protuberance of adjusting the bolt terminal surface, it is the vestibule of facing the path rank that opening is arranged in its inside of described button, and is provided with hollow sleeve pole on the vestibule medial surface, and this hollow sleeve pole leans with the spring that is nested with on the scalariform post.

Compared with prior art, advantage of the present utility model is because the contact-making surface of button described in the utility model bottom and trigger is domatic, domatic being provided with in its bottom can make trigger and button relative fixed in certain locational zigzag panel, terminal and have little groove at the zigzag panel with the trigger place of matching, and be provided with tack in the two sides of button and it is fixed on the indoor trigger of groove two medial surfaces.This structure uses not only flexibly button and trigger but also is convenient, because of its trigger and button are to be located by zigzag panel recessed joint on the button inclined-plane and the clamp on the trigger, when pressing keys, clamp on the zigzag panel recessed joint and advance, make the water pistol water flow increases, until reaching the max-flow water level, when wanting to close current, as long as press trigger squeeze, clamp and zigzag panel on the trigger are broken away from, be slope because of button again, so when both sides one break away from, trigger and button are just by separately spring force and automatically reset to original position, and open current and be clamp and advance along the recessed joint of zigzag panel, both sides reset and are contactless, therefore water pistol are placed on the there and are stained with what dust and can influence it and open and reset, do not block and cause malfunctioning shortcoming with regard to not existing naturally, so blocking or malfunctioning phenomenon of having avoided fully occurring between button and the trigger.And its seal ring of product of the present utility model is designed to circular, and is few with control bolt contact-making surface, so when opening water pistol, the resistance that its current run into is just few, also just increased the flow of water naturally, so the utility model is a kind of product that is worthy to be popularized.
