Description
Technical field
The present invention relates to folder code rifle technical field.
Background technology
Folder code rifle, also known as clasp rifle, is mainly applicable to the snapping etc. of connection between separate packed spring and mattress, sofa, seat cushions spring and frame, can effectively increases work efficiency.Structurally primarily of air valve assembly, cylinder, folder code groove, the other plate in both sides, top board, by-pass valve control, trigger and folder harbour are formed, air valve assembly is connected to the inlet end of cylinder, the other plate in both sides is connected to the end of cylinder, and connect and compose in one with top board the lance body structure being provided with gathering sill and connecting rod, folder harbour is arranged on the end of gathering sill, the code end that goes out of folder code groove connects gathering sill, during use, by by-pass valve control and the action of trigger actuated cylinder, thus drivening rod moves ahead fast along gathering sill, impact the folder code sent from gathering sill, in conjunction with the positioning action of folder harbour, folder code is made to be fixed on workpiece, simple to operate, speed is fast.But, but there is certain defect as the topmost parts-air valve assembly and control valve assembly pressing from both sides code rifle, cause the use cost of user high, difficult in maintenance.
Reason has 2 points: 1, the design of air valve assembly is unreasonable.
Current air valve assembly is formed primarily of valve pocket, spool, and valve pocket is generally mounted in the air valve cylinder sleeve of cylinder head bottom, and the bottom of air valve cylinder sleeve connects tracheae, sidepiece is provided with ventilation slotted eye, and front end is communicated with cylinder interior.Before being provided with in valve pocket, rear chamber, before spool is arranged on valve pocket, in rear chamber, be made up of the valve core head at valve core rod and valve core rod two ends, before, the sidepiece of rear chamber is respectively arranged with arc-shaped slot, the side of valve pocket is fixed in the bottom of cylinder by latch, valve pocket surface is provided with three O type sealed outer rings, one of them O type sealed outer ring is arranged between two arc-shaped slots, before two other O RunddichtringO is arranged on, the two ends of rear chamber, in order to the pressure reduction realized between air valve assembly and cylinder controls, front, the inside of rear chamber also needs installation two to seal inner ring with the O type of spool interoperation, the end face top press-fit of O type sealing inner ring and valve core head, when the spool crown is pressed on O type sealing inner ring, the passage end sealing of the chamber of mounting O-shaped sealing inner ring.As everyone knows, O RunddichtringO is all generally made by elastomeric material, because the top pressure frequently by spool acts on, just can lose efficacy after using one end time, once lose efficacy to cause Valve leakage, cause folder code rifle cisco unity malfunction, for this reason, need to carry out integral replacing to air valve assembly, at present, general air valve assembly price is 120 yuan/, normal service life is two months, for general user, its maintenance cost is too high, and this is also one of shortcoming of existing folder code rifle.In addition, sidepiece due to front chamber a and rear chamber b needs to arrange arc-shaped slot c, structure as shown in Figure 1, for ventilation, this arc-shaped slot c generally needs 3/4 of the circumference taking valve pocket, only supports as connection by remaining 1/4 position, this design is due to centre-of gravity shift, moment of torsion is comparatively large, is in use easy to cause connect support zone fracture, shortens the life-span of air valve assembly further.For this reason, those skilled in the art attempts the middle part extension supporting post at arc-shaped slot, but, owing to adding support column, can increase the intensity of valve pocket in theory, but the intake and exhaust amount but causing slotted eye reduces, after folder code of often shooting, need the interval long period could make the second rifle, significantly reduce folder code frequency, obvious this scheme is infeasible; For this reason, also someone proposes the arc-shaped slot pore that multiple circumference is arranged to substitute, but because valve pocket sidepiece also will reserve for installing alignment pin the space arranging locating hole, therefore, also cannot realize because valve pocket space surface is not enough, therefore, although the air valve assembly life-span of folder code rifle is short, maintenance cost this problem high has existed for a long time, finally still could not solve.
2, the design of control valve assembly is unreasonable.Current control valve assembly is positioned by bearing pin, the direct contact trigger of spool of control valve assembly, and the top pressure for a long time by trigger acts on, and can produce the problems such as loosening unavoidably.
Because the current air valve assembly of folder code rifle and the design of control valve assembly all exist larger defect, thus, be necessary to design a kind of more rational atmospheric control to meet the demand of user.
