Description
Technical field
The present invention relates to disposable high-speed turbine heads.
Background technology
For air turbine handpiece on the market using handpiece case, handpiece case upper end cover sets superstructure at present.In machine
It needs to set inlet channel, vapor channel, exhaust passage in head shell production process, complex production process makes trouble, can not
Pass through simple die casting, injection support.In addition, head, during the work time since work piece weight is small, head wall surface thin and thick is uniform,
Easily generate vibration.
The content of the invention
In order to overcome the above-mentioned deficiency of existing turbine head, the present invention provides a kind of disposable high-speed turbine head.
The present invention the technical solution to solve the technical problem is that：Disposable high-speed turbine head is equipped with connection including rear end
The handpiece case of handle, the connection handle are equipped with inlet channel and exhaust passage, and the handpiece case is by left housing and right shell group
Into the left housing is connected middle part with right shell and forms air impeller chamber.
Further, the left housing is equipped with protrusion with right shell front end, and the left housing on the protrusion of right shell front end with being respectively equipped with
Mounting hole, fixed column, the left housing are fixed with right shell front end by above-mentioned mounting hole with fixed column.Protrusion is set to increase counterweight,
Improve head stability.
Preferably, the left housing is respectively equipped with the second mounting hole and the second fixed column with right shell rear end.
Preferably, the left housing handle portion is equipped with left steam slot, the right shell handle portion is equipped with right steam slot, the left side
Steam slot forms vapor channel with right steam slot.
Preferably, first mounting hole is riveting hole, first fixed column is riveting column.
Preferably, the enterprising air drain is equipped with tilting section, the tilting section and air impeller at air impeller chamber
Chamber side wall is into near-tangential direction.
Preferably, the left housing is fine grinding face with right shell contact surface.The contact of upper casing lower casing is ensured using the contact of fine grinding face
It is firm.Rubber seal further can also be used to be sealed, the rubber seal is arranged on the upper casing and contacts with lower casing
Between face.
Sealing function is further functioned as, outer surface is enclosed with sealant after the left housing is fastened with right shell.
Head counterweight reduces the vibration of head side wall when in use, improves product stability, when in use only need to be by gas
Dynamic component is inserted, and left housing, which is fastened and sealed with right shell, can be used.
The beneficial effects of the present invention are：It is simple in structure convenient for production, the product life that greatly reduces that increased production cost
Rate is produced, product vibration is greatly reduced, improves operational stability.
