Abstract
The utility model provides a limit structure of a plugging handle threaded connecting sleeve of a scaling machine; the limit structure is characterized in that: a convex ring arranged at the middle part position of the threaded connecting sleeve is matched with a circular ring at the end part of the lower shell of the plugging handle, and the outer diameter of the circular ring of the end part of the lower shell of the plugging handle is more than that of the convex ring on the middle position of the threaded connecting sleeve; in the way, the threaded connecting sleeve is assembled artificially, the threaded connecting sleeve can be directly screwed in the lower shell until the convex ring at the middle position of the threaded connecting sleeve is contacted with the circular ring on the end part of the lower shell of the handle, so as to greatly avoid negative effect caused by manual control and ensure effective power of the handle.
Description
Technical field
This utility model relates to a kind of machine plug-in type handle that cleans one's teeth.Especially the machine of cleaning one's teeth patches the position limiting structure that handle is threaded and overlaps.
Background technology
Present domestic existing ultrasonic cavitron plug-in type handle wherein has between a upper casing that patches handle and the lower casing to be provided with the cover that is threaded, and being threaded to overlap couples together upper casing and lower casing.Be enclosed within twisting when being assembled to lower casing but be threaded, because of spacing fastening structure is not set in lower casing, but to make be threaded overlap turn-knob in the lower casing more deeply, also can be more shallow; So just cause, if be threaded the cover turn-knob in the lower casing more deeply, the effective power of handle can weaken; Will cause the handle noise big on the contrary, power also is difficult to guarantee; When workman assembling is threaded cover, also be difficult to the handle degree of depth of cover turn-knob in the lower casing that be threaded.
The utility model content
The purpose of this utility model is that a kind of novel, not only simple but also practical structure of design comes spacing retaining thread adapter sleeve turn-knob to enter the position of lower casing.
Technical solution adopted in the utility model is:
Implement principle: the end annulus that this utility model utilization patches the handle lower casing limits the degree of depth of cover turn-knob in the lower casing that be threaded.
Architectural feature is: the annulus of establishing on establishing bulge loop and patch handle lower casing end on the cover medium position that is threaded matches.
The external diameter that patches the annulus on the handle lower casing end is bigger than the external diameter of the bulge loop on the cover medium position that is threaded.
Like this, when workman assembling is threaded cover,, contact until establishing the annulus of establishing on bulge loop and the handle lower casing end on the cover medium position that is threaded just directly being threaded the cover turn-knob in lower casing; Just avoid the very important person to control the adverse consequences that is caused greatly, thereby guaranteed the effective power of handle.
Description of drawings
Fig. 1: the machine of cleaning one's teeth patches the assembly structure figure that handle is threaded and overlaps.
Fig. 2: the machine of cleaning one's teeth patches the handle cover view that is threaded.
Among the figure: 1, patch the handle upper casing, 2, sealing ring, 3, the cover that is threaded, the bulge loop of 3-1, the cover that is threaded, 4, patch the handle lower casing, 4-1, patch the end annulus of handle lower casing.
The specific embodiment
This utility model is to improve on the existing machine of cleaning one's teeth patches the basis of handle, comprise: patch handle upper casing 1, patch handle lower casing 4 and the cover 3 that is threaded, the round 4-1 that establishes on establishing bulge loop 3-1 and patch handle lower casing 4 ends on cover 3 medium positions that are threaded matches.The external diameter that patches the annulus 4-1 on handle lower casing 4 ends is bigger than the external diameter of the protruding 3-1 on cover 3 medium positions that are threaded.
Cover 3 turn-knobs that are threaded are fitted into and patch 4 li of handle lower casings, contact with the end annulus 4-1 that patches handle lower casing 4 until the bulge loop 3-1 of the cover that is threaded; Then sealing ring 2 is packed into and patch on handle upper casing 1 end, then be threaded onto on the cover 3 that is threaded patching handle upper casing 1.
Claims (2)
1. the machine of cleaning one's teeth patches the position limiting structure that handle is threaded and overlaps, comprise: patch handle upper casing (1), patch handle lower casing (4) and the cover (3) that is threaded, it is characterized in that: the circle of establishing on establishing bulge loop (3-1) on cover (3) medium position that is threaded and patching handle lower casing (4) end (4-1) matches.
2. the machine of cleaning one's teeth as claimed in claim 1 patches the be threaded position limiting structure of cover of handle, it is characterized in that: the be threaded external diameter of protruding (3-1) on cover (3) medium position of the external diameter ratio that patches the annulus (4-1) on handle lower casing (4) end is big.
