Specific implementation mode

Aforementioned and other technology contents, feature and effect in relation to the utility model, in following cooperation with reference to figures 1 through figure In the detailed description of 3 pairs of embodiments, can clearly it present.The structure content being previously mentioned in following embodiment is with explanation Book attached drawing is reference.

Each exemplary embodiment of the utility model is described below with reference to accompanying drawings.

Embodiment one, the utility model are a kind of valve collet Manual disassembling tool, include handle 1, handle 1 be for Facilitate when the operation tool pressing to use, further includes having a dismounting loop bar 3, it is axial among dismounting loop bar 3 to offer two Holding penetrating limiting through hole 5, handle 1 is connect with dismounting loop bar 3, and specific installation is to fix the lower end of handle 1 when producing In in limiting through hole 5, it is connected with compressed spring 4 in 1 lower end of handle, compressed spring 4 is placed in limiting through hole 5, and compressed spring 4 is also It is connected with the dismounting head 2 being placed in limiting through hole 5, and the connection type of compressed spring 4 is as conventional springs connection type, example It such as can be to be fixedly connected with the draw ring of attachment through the drag hook on spring, or welding, or other connection sides Formula.

Embodiment two specifically in processing, limiting through hole 5 is designed as ladder-like on the basis of embodiment one Distribution, and the diameter of limiting through hole 5 becomes smaller successively from top to bottom, and in order to preferably express, we are by the stair-stepping limit Position through-hole 5 is referred to as higher level's through-hole 6, intermediate through-hole 7, subordinate's through-hole 8.

Embodiment three, in order to dismounting loop bar preferably coordinate, handle 1 is designed as justifying on the basis of embodiment one Cylinder, and in order to preferably facilitate worker hand-held, the upper end of handle 1 is designed as inverted cone.

Example IV, on the basis of embodiment two, 1 lower end of the handle is connected with press head 9, convenient for pressing pressure Contracting spring 4, press head 9 are fixed in higher level's through-hole 6, and 9 diameter of press head is less than 1 diameter of handle, and handle 1 is made to cannot be introduced into higher level In through-hole 6, prevent from firmly excessive when dismantling valve collet valve collet being caused to damage.

Embodiment five, on the basis of embodiment three, the dismounting loop bar 3 is cylindrical sleeve to be made with reducing frictional force The operation is more convenient, laborsaving, while being also convenient for worker's gripping, and 3 lower end of dismounting loop bar offers circular trough 10, in dismounting valve It when locker, is supported on valve housing, valve collet Manual disassembling tool is made to be easier stress, while being also prevented from firmly excessive lead Cause valve collet damage.

Embodiment six, on the basis of embodiment two, the compressed spring 4 is placed in intermediate through-hole 7, is standard component, Specification is SUML-D10-L50, and compressed spring 4, which is set as standard component, to be convenient for being replaced in repair.

Embodiment seven, on the basis of embodiment two, the dismounting head 2 is cylinder, to reduce friction, convenient for pressing Pressure improves working efficiency, dismantles and is arranged with fixed round platform 11 on head 2, and fixed round platform 11 is placed in intermediate through-hole 7, and diameter is big It in subordinate's through-hole 8, prevents dismounting head 2 from deviating from, part is caused to be lost, 11 upper end of fixed round platform is equipped with the pressure being connect with dismounting head 2 Contracting spring 4, compressed spring 4 are fixed on through hook, link on dismounting head 2 and press head 9, prevent compressed spring 4 from taking off during exercise Valve collet Manual disassembling tool is caused to fail from press head 9 and dismounting head 2.

Embodiment eight, on the basis of embodiment two, 8 bottom end of subordinate's through-hole is fixed with annular magnet 12, described 12 magnetism of annular magnet be distributed on the inner headed face of annular magnet 12, for adsorbing the valve collet disassembled, prevent gas Grille clip is lost in disassembly process, and dismounting head 2 passes through annular magnet 12 and can be realized in annular magnet 12 and slided up and down.

Embodiment nine, on the basis of embodiment eight, 3 material of dismounting loop bar is 45# steel, and 45# hardness of steel is high, Toughness is strong, and wear-resisting property is outstanding, provides guarantee for the long-time use of valve collet Manual disassembling tool, dismantles 2 material of head For AISI304 stainless steel materials, dismounting head 2 is prevented to be sucked by annular magnet 12, increases dismounting difficulty；Secondary, because dismantling head 2 It is long-term it is exposed work outside, dismounting environment is complex, stainless steel material can effective pre- Anti-dismantling head 2 corrosion, can be effective Increase life tools.

When specifically used, when mounted, compressed spring 4 is in compressive state to initial state, and dismounting head 2 is popped up, torn open outward First 2 top and the bottom surface level of dismounting loop bar 3 are unloaded, 1 top of handle is held, the circular trough 10 for dismantling 3 lower end of loop bar is gentle Door shell agrees with, and pushes handle 1, and dismounting head 2 withstands air valve shaft, and air valve shaft so that dismantle head 2 withstands compressed spring 4, gas upwards Grille clip is removed, and the pressure valve clamp on air valve shaft is acted on by annular magnet 12, is attracted to the lower end of dismounting head 2, finally Release handle 1, compressed spring 4 push downwards dismounting head 2, dismounting head 2 are made to return to initial position, dismantle the material of head 2 not by ring Shape magnet 12 attracts, and therefore, is not influenced by annular magnet 12 in moving process, leads to since fixed round platform 11 is stuck in middle rank Reason in hole 7, therefore, the outside distalmost end of dismounting head 2 are exactly to maintain an equal level with the bottom surface of dismounting loop bar 3.

The utility model clever structure, it is easy to use, it is easy to operate, a people can complete independently, production efficiency is high, has Effect solve traditional-handwork dismounting cylinder head valve locker it is inconvenient, laborious, valve collet is fragile, easy to be lost asks Topic.
