Description

A kind of device for plugging

Technical field

The utility model relates to a kind of motorcycle engine, is specifically related to be applied to the device for plugging of motorcycle engine.

Background technology

At the production field of motorcycle engine, all must carry out the dry type leak detection usually to the engine that assembles.At present the device for plugging that engine is carried out the dry type leak detection mainly comprises the handle that front end has the core bar of reverse taper, is fitted in screw thread expand head on this core bar, top iron successively, connects with movement parts every iron, movement parts, by connector, wherein, connection part before the outer periphery of top iron is equipped with, should before the connection part an end be connected every iron, the other end is inserted in screw thread expand head; Top iron and between iron, be fitted with little spring; Between iron and movement parts, be fitted with big spring; The periphery of this big spring is covered with housing, and an end of this housing links to each other with movement parts, and the other end is enclosed within on the preceding connector; The periphery of screw thread expand head also is covered with edge face sealing member, and this edge face sealing member one end and screw thread expand head are fixed, and the other end is inserted in preceding connection part and fixes with housing; The end that above-mentioned housing links to each other with movement parts also is connected with square groove, and movement parts and handle promptly are positioned at this square groove.The device for plugging of this structure need connect ventilating joint separately when engine is hunted leak, its leak stopping and ventilation need two procedures just can finish, and use very inconvenience, and work efficiency is on the low side.

The utility model content

The purpose of this utility model provides a kind of device for plugging, and this device need one procedure can be finished the leak detection work to engine.

The purpose of this utility model is achieved through the following technical solutions: a kind of device for plugging, comprise the core bar that has reverse taper, screw thread expand head, top iron, little spring, every iron, big spring, movement parts, by handle, housing, preceding part, edge face sealing member and square groove that connector is connected with described movement parts, described connector is to be provided with the cavity a that passes for described core bar more than 2 and between the connector; The afterbody of described handle is provided with cavity b; Described core bar is provided with through hole, and this through hole communicates with the external tracheae that passes described cavity a and be enclosed within on the described core bar.

For the external tracheae that prevents to be enclosed within on the described core bar comes off in the process of work, an end that is connected with described external tracheae on the described core bar is tapered and be provided with projection.

The utility model is provided with through hole on core bar, and adopt the mode of duplex fitting that handle and movement parts are fixed, promptly between connector, leave the cavity a that passes for core bar, afterbody at handle is provided with the cavity b that passes through for external tracheae simultaneously, thereby external tracheae passes cavity b and is enclosed within on the core bar, realize that external tracheae is connected with the through hole of core bar, search gas can be entered in the detected engine from through hole and external tracheae, therefore only need a procedure can realize leak stopping and ventilation, simplified leak detection work, its use is very convenient, and has improved work efficiency; The end that core bar is connected with external tracheae in the utility model is tapered and be provided with projection, thereby can also prevent that when making things convenient for the external gas pipe box to go into core bar external tracheae from coming off in the course of the work, and it is simple in structure, loads and unloads also very convenient.

Description of drawings

Fig. 1 is the structural drawing on the positive apparent direction of device for plugging among the utility model embodiment 1.

Fig. 2 is the schematic perspective view of handle among Fig. 1.

Fig. 3 is that connector promotes the partial structurtes synoptic diagram that movement parts moves ahead when pinching lower handle among the embodiment 1.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but therefore the utility model is not limited among the following concrete mode.

Embodiment 1: as Fig. 1～shown in Figure 4, a kind of device for plugging, comprise the core bar 2 that has reverse taper 1, screw thread expand head 3, top iron 4, little spring 5, the handle 10, housing 11, preceding part 17, edge face sealing member 12 and the square groove 13 that are connected with movement parts 8 every iron 6, big spring 7, movement parts 8, by connector 9, connector 9 is 2, and is provided with the cavity a14 that passes for core bar 2 between the connector 9; The afterbody of handle 10 is provided with cavity b15; Core bar 2 is provided with through hole 2-1, and this through hole 2-1 communicates with the external tracheae 16 that passes cavity b15 and be enclosed within on the core bar 2; An end that is connected with external tracheae 16 on the core bar 2 is tapered and be provided with protruding 2-2.

Pinch lower handle 10, movement parts 8 moves ahead under the effect of connector 9 and compresses big spring 7, big spring 7 is again by acting on little spring 5 and little spring 5 being discharged every iron 6, top iron 4 under the effect of little spring 5 to sinciput screw thread expand head 3 until preceding part 17 spacing places, meanwhile movement parts 8 drives core bar 2 and is still moving a bit of distance forward, thereby make the reverse taper 1 of core bar 2 thoroughly break away from screw thread expand head 3, to guarantee this screw thread expand head 3 retracted for clearance.

Discharge handle 10, big spring 7 resets, big spring 7 acts on movement parts 8 in this process, this movement parts 8 drives core bar 2 and retreats, thereby the reverse taper of core bar 21 expansion screw thread expand head 3, make the sealing workpiece of screw thread expand head 3 and the engine location, back that fits, meanwhile big spring 7 continues to act on movement parts 8, make movement parts 8 drive the core bars 2 a bit of distance of reruning backward, since screw thread expand head 3 with above-mentioned sealing workpiece alignment restrictions retreating of core bar 2 and movement parts 8, so big spring 7 by connection part 17 and edge face sealing member 12 before iron 6 acts on, passes through the sealing workpiece of edge face sealing member 12 canned motors again.
