Description

Pneumatic lapper combined type exhaust apparatus

The utility model relates to a kind of exhaust apparatus, especially relates to the combined type exhaust apparatus of pneumatic lapper.

General common pneumatic lapper is equipped with an air inlet and gas outlet on it, be made for moving air flow and enter by air inlet and drive driving mechanism in the body, is discharged by the place, gas outlet again.Generally speaking, this pneumatic lapper of commonly using can be divided into and not inhale formula and self-priming two kinds.Formula do not inhaled in title, is the air-flow at place, gas outlet is directly discharged; And claim self-primingly, and be to be extended with a bifurcated pipe with looped pipeline in gas outlet place, when the air-flow of exhaust outlet is discharged, make air-flow in the looped pipeline by bifurcated pipe, also be subjected to the air-flow draw and discharge, and reach the effect of looped pipeline dust suction thus.

Yet above-mentioned formula and the self-suction type pneumatic grinder do not inhaled is to belong to two kinds of different types, that is, when the housing of pneumatic lapper is made, be fixed as and do not inhaled formula or self-priming; Therefore, general pneumatic lapper is only can have not inhale formula or self-priming both one, and is like this then cause the scope of application of pneumatic lapper to be restricted.

The purpose of this utility model is to provide a kind of pneumatic lapper combined type exhaust apparatus, its can make pneumatic lapper according to actual needs and Fast transforms be combined as and do not inhale formula or self-priming type.

For achieving the above object, the utility model provides a kind of pneumatic lapper combined type exhaust apparatus, and it includes:

One body is the housing of pneumatic lapper, offers an air inlet, an exhaust outlet and a suction port on this body, is provided with screw thread in exhaust outlet;

One can with this exhaust outlet mutually spiral shell establish the sound-absorptive connector of combination, this sound-absorptive connector one end is an erase head and the other end is a leakage port, be provided with first between this erase head and the leakage port and combine screw thread,

It is characterized in that:

This exhaust outlet is to link joint and connect bifurcated pipe and be mounted on this exhaust outlet with one, an end of this bindings joint be erase head and the other end for losing heart adapter, be provided with second between the two ends of this binding joint in conjunction with screw thread; This connects bifurcated pipe, be tubulose, one end opening is a connecting portion and other end opening is the junction surface, be provided with a looped pipeline in extending to be communicated with in addition between this connecting portion and the junction surface, the looped pipeline openend is a fit portion, this jointing screws togather in conjunction with screw thread and exhaust outlet are mutually sheathed by second, and this fit portion that connects bifurcated pipe combines with the suction port socket, and this junction surface and this mutually sheathed combination of adapter of losing heart; And when the sealing of the suction port of this body, then directly with sound-absorptive connector first in conjunction with screw thread, make this sound-absorptive connector and the mutually sheathed combination of this exhaust outlet.

After having adopted said structure, pneumatic lapper combined type exhaust apparatus of the present utility model, it is established to combine and can constitute by the body and the group of sound-absorptive connector and is not inhaled formula pneumatic lapper type; And cooperate binding joint and connection bifurcated pipe can constitute self-suction type pneumatic grinder type with body.Thus, make the visual reality of the utility model needs and fast group establish and be transformed to the pneumatic lapper of not inhaling formula or self-priming arbitrary type.

Below, with specific embodiment the utility model is done further detailed description in conjunction with the accompanying drawings.

Fig. 1 is that the utility model constitutes the perspective exploded view of not inhaling formula pneumatic lapper pattern.

Fig. 2 is the schematic perspective view after Fig. 1 makes up.

Fig. 3 links joint and the perspective exploded view that is connected bifurcated pipe in the utility model.

Fig. 4 is the schematic perspective view of the utility model as self-suction type pneumatic grinder exhaust apparatus.

As shown in Figure 1, 2, 3, a kind of pneumatic lapper combined type exhaust apparatus that the utility model embodiment is provided, it mainly is to constitute with a body 10, a sound-absorptive connector 20 not inhale the formula structure; Connect the self-priming structure of bifurcated pipe 40 formations and link joint 30 and with a body 10; Wherein:

This body 10 is the housing of pneumatic lapper, offers air inlet 11, exhaust outlet 12 and the suction port 13 of tubulose on it; This air inlet 11 is the air inlet power resources as pneumatic lapper, and air inlet 11 is provided with air intake assembly 111, be provided with screw thread 121 in exhaust outlet 12 end inwalls, and this suction port 13 is to be connected with the housing bottom of pneumatic lapper;

This sound-absorptive connector 20 is that combination is arranged at exhaust outlet 12 places, and the one end is an erase head 21, and the other end is disappointing 22, and erase head 21 is connected with disappointing 22, forms one first in conjunction with screw thread 23 between the two; In view of the above, this sound-absorptive connector 20 is arranged in the exhaust outlet 12, and by first in conjunction with the screw thread 121 of screw thread 23 and exhaust outlet 12 mutually spiral shell establish in conjunction with and dismantle; Suction port 13 in body 10 seals the not time spent with blocking 14, be with sound-absorptive connector 20 by it first in conjunction with screw thread 23 and exhaust outlet 12 mutually sheathed screwing togather, this moment, suction port 13 did not have effect, the gas of discharging from exhaust outlet 12 places is discharged after then directly by erase head 21 noise reductions extraneous, and what so promptly constitute pneumatic lapper does not inhale formula structure (as shown in Figure 2).

This links joint 30, and the one end is an erase head 31, and the other end takes over 32 for losing heart, and forms second between the two in conjunction with screw thread 33; Link joint 30 and be by second in conjunction with screw thread 33 with exhaust outlet 12 screw threads 121 mutually sheathed screwing togather;

This connects bifurcated pipe 40, is tubulose, and the one end opening is a connecting portion 41, and other end opening is junction surface 42, extends in addition to be communicated with between the two to form a looped pipeline 43, and looped pipeline 43 openends are fit portion 431.In view of the above, in jointing 30 second in conjunction with screw thread 121 mutually sheathed screw togather of screw thread 33 with exhaust outlet 12, and the fit portion 431 that connects bifurcated pipe 40 combines with suction port 13 sockets, and when junction surface 42 with lose heart to take over 32 mutually sheathed in conjunction with the time, promptly constitute the self-priming structure of pneumatic lapper, that is, when the air-flow of exhaust outlet 12 is discharged, make air-flow in the looped pipeline 43 by connecting bifurcated pipe 40, also be subjected to the air-flow draw and discharge, and reach the effect (as shown in Figure 4) of looped pipeline 43 dust suctions thus.
