here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
can be provided with between said brush head and lower link and press brush spring assembly; Pressure brush spring assembly comprises brush stroke and pressure brush spring; On lower link, level is installed with brush stroke; Brush stroke is provided with the brush head of the inside and outside movement of energy; Brush stroke between lower link and brush head is provided with pressure brush spring.
in above-mentioned cannula tip, centralizing bracket can comprise rotary head installation sleeve and righting strut; At least two vertical righting struts are fixed with in the exterior periphery of rotary head installation sleeve; Limited location snap ring is fixed with between righting strut below rotary head installation sleeve; Be provided with annular distance at the middle part of limited location snap ring, the middle part of the rotary head support corresponding with annular distance is installed with rotating shaft, and rotating shaft bottom is provided with external screw thread, and the lower end of rotating shaft is passed annular distance and is installed with stop nut by screw thread.
the upper end of above-mentioned rotating shaft can be fixed with crank handle.
rotary head pedestal lower end in above-mentioned cannula tip outside centralizing bracket can be installed with two lower links, and two lower links are installed with brush head respectively, in upper and lower cross-distribution between two brush heads.
the utility model reasonable and compact in structure, easy to use; Manually rotate crank handle, rotary head supporting band electric brush head rotates, and hold realization to scrub to the pin thread (external screw thread) of sleeve pipe, simple to operation, shorten scavenging period, cleaning efficiency is high; In the process of scrubbing, in cannula tip, centralizing bracket can make rotary head support rotate along cannula center, coordinates pressure brush spring assembly simultaneously, effectively improves the cleaning effect that brush head is scrubbed.
Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks sectional structure schematic diagram.
accompanying drawing 2 is the A-A sectional structure schematic diagram of accompanying drawing 1.
coding in accompanying drawing is respectively: 1 is rotary head support, and 2 is lower link, and 3 is brush head, and 4 is brush stroke, and 5 is pressure brush spring, and 6 is rotary head installation sleeve, and 7 is righting strut, and 8 is limited location snap ring, and 9 is rotating shaft, and 10 is stop nut, and 11 is crank handle.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1,2, this sleeve pipe pin thread cleaning device comprises centralizing bracket in cannula tip, rotary head support 1 and brush head 3; In cannula tip, the upper end of centralizing bracket is provided with the rotary head support 1 of energy radial rotary, the lower circumferential of the rotary head support 1 in cannula tip outside centralizing bracket is fixed with at least one lower link 2, and lower link 2 is installed with brush level brush head 3 inwardly.When the pin thread (external screw thread) of cannula cleaning is held, first centralizing bracket in cannula tip is inserted in sleeve pipe, enables the bristle of brush head 3 the inner be fitted on sleeve pipe pin thread; Manual rotation rotary head support 1, drive brush head 3 to remove foul along the thread groove rotary scrubbing on sleeve pipe pin thread, simple to operation, shorten scavenging period, cleaning efficiency is high; In cannula tip, centralizing bracket can make rotary head support 1 placed in the middle on sleeve pipe, guarantees that rotary head support 1 can rotate along cannula center, improves the cleaning effect of brush head 3, clean cleaner; Avoid after causing sleeve pipe to enter well because of cleaning dirty, the accident that sleeve pipe installs difficulty and Joint failure risk occurs.
