Abstract

The utility model relates to a piston striker for a nailing machine, which mainly makes the fixing end of the striker form an enlarging T-shaped sawtooth head; the fixing end of the striker is integrally connected to the inner part of a piston when the piston is molded into forming, and a piston striker component which is suitable for mass production is formed; in this way, the purposes of simplifying processing and assembling processes, reducing cost and improving the whole structure strength can be achieved.

Description

Piston striker for nailing machine

The utility model system is relevant for the piston striker of nailing machine, especially refer to that a kind of piston striker structure with pneumatic stapler adds improved design again, and make its striker when piston is molded and shaped, one is connected in internal piston, constitute an assembling whereby and can reduce production costs easily, and the splendid piston striker of structural strength.

The piston striker of early stage nailing machine, roughly as shown in Figure 1, its structure mainly is made up of members such as striker 10, chuck handle 11 and piston pedestals 12, wherein, one of striker 1 end offers a lockhole 13, and its end can be inserted in the clip slot 14 of chuck handle 11 lower ends, and wear connection by means of a spring catch 15, these chuck handle 11 stage casings then have external screw thread 16 in addition, can be for screw 17 interlockings within the

piston pedestal

12,18 of the outer grooves of its piston pedestal 12 can sheathed O type circle 19 in addition, constitutes its piston firing pin assembly whereby.

Though above-mentioned known structure has the basic function of piston striker, but because its modular construction is rather complicated, so processing, the assembling comparatively the trouble and production cost higher, for overcoming this shortcoming is that the someone develops another striker piston connection structure, as shown in Figure 2, it mainly is to be formed with embedding at piston 20 1 ends to hold portion 21 that this striker piston connects structure, this embedding is held portion 21 bottoms and is offered clip slot 22, can insert for striker 23 1 ends, and its embedding is held portion 21 outer ends and is covered with a sleeve 24, this sleeve 24 is held portion 21 and the corresponding lockhole that offers with embedding, but supply and marketing axle 25 wears with the solid striker 23 of pin, though connecting the more early stage piston striker structure of structure, the striker piston of this improvement simplifies practicality, and get permission patent (announcing No. 192777), piston still need be offered clip slot in right its structure, pin-and-hole also covers sleeve, and sleeve and striker also all need be offered pin-and-hole, and the mat bearing pin is with this piston, the combination of striker pin joint, therefore, the assembling processing that this striker piston connects structure still belongs to complicated loaded down with trivial details, and the assembly precision of each member needs good, otherwise promptly easily produce the bad product of structural strength, so the imperfection practicality.

The main purpose of the utility model is to provide a striker with T shape sawtooth head, and make this striker when piston is molded and shaped, one be connected in internal piston, make the assembly of nailing machine striker and piston more simplify practicality whereby, and make it be suitable for a large amount of productions, thereby reduce production costs and improve the stability of product structure intensity.

Provide a kind of piston striker of nailing machine according to the utility model, be made up of jointly striker and piston, wherein striker can directly strike out strip, and is connected with in the piston chamber that is arranged at nailing machine with piston; It is characterized in that: striker is formed with the head of increasing in addition at its stiff end that is connected with piston, and this striker can be inserted in the mould of piston, and fitting piston is molded and shaped, makes the enlarged head of striker directly connect moulding with piston only; Its feature is that also the enlarged head of striker can be T-shaped, and makes striker respectively be formed with the sawtooth ditch in the lamellar body both sides near T shape head, makes T shape head and sawtooth ditch be connected in piston only inside whereby, so that strengthen the intensity of striker and piston structure.

For ease of the architectural feature that more clearly understands the utility model and purpose thereof, effect, existing conjunction with figs. is described in detail as follows:

Fig. 1 is the STRUCTURE DECOMPOSITION figure of known product.

Fig. 2 is the structure cutaway view of another known product.

Fig. 3 is the STRUCTURE DECOMPOSITION figure of the utility model.

Fig. 4 is the structure cutaway view of the utility model.

Fig. 5 is the enforcement signal of the utility model.

See also Fig. 3, shown in 4, the piston striker structure of the nailing machine of the utility model mainly is made of jointly striker 3 and piston 4, and wherein striker 3 can directly strike out strip, and be connected with piston 4 with in the piston chamber 5 that is arranged at nailing machine (as shown in Figure 5), realize pneumatic nailing operation whereby.

The improvement of the striker 3 of the utility model is that mainly the stiff end that is connected with piston 4 is formed with the T shape head 30 of increasing in addition, and make this striker 3 respectively be formed with sawtooth ditch 31 in lamellar body both sides near T shape head 30, again striker 3 is inserted in the mould of piston 4, and fitting piston 4 is molded and shaped, makes the head 30 of striker 3 be linked to piston 4 inside with sawtooth ditch 31 one.

Above-mentioned improved piston 4 and striker 3 assemblies, because striker 3 direct punching presses are made, need not to establish in addition pin-and-hole, and can be directly and 4 one-body molded connections of piston, therefore, piston 4 also need not the structure of processing in addition and striker 3 windings, is suitable for a large amount of productions and reduces processing, assembling operation so both can reach, with the purpose that reduces production costs, more can make the quality of piston firing pin assembly more become superior stable; In addition, because the enlarged head 30 and the sawtooth ditch 31 thereof of its striker 3 are to be embedded in piston 4 body interior, therefore, its overall structure is except that being easy to production, and the structural strength of integral body is also preferable, can use for a long time and not have the anxiety that gets loose, so can promote the practical effect of product.

Claims

1, a kind of piston striker of nailing machine is made of jointly striker and piston, and wherein striker can directly strike out strip, and is connected with in the piston chamber that is arranged at nailing machine with piston; It is characterized in that: striker is formed with the head of increasing in addition at its stiff end that is connected with piston, and this striker can be inserted in the mould of piston, and fitting piston is molded and shaped, makes the enlarged head of striker directly connect moulding with piston only.

2, the piston striker of nailing machine according to claim 1, the enlarged head that it is characterized in that striker can be T-shaped, and make striker respectively be formed with the sawtooth ditch in lamellar body both sides near T shape head, make T shape head and sawtooth ditch be connected in piston only inside whereby, so that strengthen the intensity of striker and piston structure.
