Specific embodiment
As shown in Figure 1 and Figure 2, the present invention provides a kind of pin hole protective devices for piston ink-jet, including 10 He of shank
Insertion section 20, the insertion section 20 cooperate with piston pin hole, and one end on the insertion section 20 far from shank 10 is fixed with
Magnet 30, wherein magnet 30 can use Nd-Fe-B permanent magnet, since piston material is mostly aluminium alloy structure, do not have ferromagnetic
Property, thus with magnet 30 using non-interference, which passes through the design of magnet 30, is being inserted into the protective device
When in piston pin hole, can attract each other with the magnet on the protective device that is arranged in corresponding position pin hole, improve its
Fixed effect in piston rotary course, to prevent it from falling off from pin hole, beneficial effect is significant.
Further, as shown in figure 3, figure 4 and figure 5, the shank 10 includes handle 11, and 11 side of handle is provided with
Step 12 is blocked, described block on step 12 has connecting pin 13 away from the side of handle 11；In the insertion section 20 with connect
13 corresponding positions are held to be provided with fastening end 22, the fastening end 22 and connecting pin 13 are mutually chimeric；It is remote on the insertion section 20
One end from shank 10 is provided with magnet accommodating chamber 21, and the magnet 30 is entrenched in magnet accommodating chamber 21；The technical solution mentions
Supplying shank 10 and the insertion section 20 of a kind of specific structure, the connecting pin 13 of shank 10 is fitted in fastening end 22 by when use,
It realizes the relatively fixed of shank 10 and insertion section 20, then magnet 30 is placed into magnet accommodating chamber 21, realize 30 He of magnet
Insertion section 20 it is relatively fixed, then insertion section 20 is inserted into piston pin hole, and blocking step 12 then can further mention
Covering effect of the height to pin hole.
Further, 13 head of connecting pin has ball bumps 14, and the ball bumps 14 effect in this is to mention
The fastness of structure after high connecting pin 13 cooperates with fastening end 22.
In the above-described embodiments, fluid-filled in the insertion section 20,20 shape of insertion section has under external force
Followability；The fluid be gas or liquid, the insertion section 20 have outer wall 23, the outer wall 23 under external force or
Deformation can be generated under internal flow compressing.This insertion section 20 can be made of rubber material, when being filled with gas in rubber
Afterwards, insertion section 20 can have the function of certain deformation, and the program utilizes the function, improve to the suitable of the pin hole of various structures
With property, such as oval pin hole, inside trumpet shaped pin hole etc., because of the insertion section without targetedly designing different fit structures
20；And since there are errors for manufacture craft, the pin hole of same specification again nuance, at this time according to same fixation
It is poor that the insertion section 20 of shape can also lead to the problem of the two fiting effect.
Further, 23 cylindrical form of outer wall of the insertion section 20, the insertion section 20 are wrapped with soft bed course
40, the bed course 40 cooperates with piston pin hole, which passes through the structure for limiting insertion section 20, and in insertion section
Soft bed course 40 is added outside 20, improves the fiting effect to piston pin hole.
Further, as shown in fig. 6, the bed course 40 has cavity 41,41 side of cavity has opening, described
Cavity 41 and the mutual fitting in insertion section 20；The thick end 42 and Bao Duan 43 that 40 side of bed course has thickness different, the thickness end
42 is close to shank 10 and ipsilateral with the opening of cavity 41, it is described thickness end 42 and Bao Duan 43 between formed inclined-plane 44, the structure with can
After the insertion section 20 of deformation cooperates, when the pin hole protective device in use, due to piston rotation, magnet 30 is due to self inertia
Centrifugal force is generated, which will bring it about the deformation of 23 evagination of outer wall from inside compressing insertion section 20, and then promote bed course
Elastic deformation occurs for 40 inclined-plane 44, so that inclined-plane 44 preferably be made to fit to inside pin hole, improving should in piston rotary course
The fixed effect of device.
Further, the end on the bed course 40 far from shank 10 is bottom surface 45, which can spray in graphite
Magnet 30 is protected during painting, meanwhile, bed course 40 can be used with recoverable material after elasticity and stress, such as
It is made of sponge.
