Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right",
The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Referring to Fig.1-3, in a kind of enlarged body narrow openings and channel device, including handle 1 and be movably arranged on handle 1
Multiple faggings 4 of one end, handle 1 are equipped with multiple installation sheets 11 close to one end of fagging 4 is equidistant, and each fagging 4 is close to hand
One end of handle 1 is mounted on movable block 12, and bayonet is offered on movable block 12, strut 13 is equipped in bayonet, and strut 13 is living
Dynamic to be plugged on installation sheet 11, fagging 4 is center of circle rotation with strut 13, and handle 1 is equipped with circular cowling 7 close to one end of fagging 4, often
It is respectively connected between the lateral wall and circular cowling 7 of a fagging 4 and pushes spring, under natural conditions, push spring for fagging 4 to handle
1 central axes push, and fagging 4 collapses, and setting circular cowling 7 not only can provide stress point to spring is pushed, while can will push
Spring is separated with human body, avoids scuffing or bacterium infection.
The inside of handle 1 is equipped with driving motor 2, and the drive shaft of driving motor 2 is extended to outside handle 1 and is fixedly connected with
Threaded rod 3 is threaded with flexible staybolt ball 5 on threaded rod 3, offers on flexible staybolt ball 5 and the intermeshing screw thread of threaded rod 3
Hole, and flexible staybolt ball 5 is located at the inside of fagging 4, each fagging 4 are arcuate structure, fagging 4 be collectively formed when being closed one it is whole
The internal diameter of circle, the full circle that fagging 4 is formed when being closed is two centimetres smaller than the outer diameter of flexible staybolt ball 5, and flexible staybolt ball 5 will be supportted
Plate 4 struts, and handle 1 is symmetrically installed close to one end of fagging 4 there are two guide rod 6, offers and guide rod 6 on flexible staybolt ball 5
Mutually matched pilot hole.
Two guide rods 6 limit the rotatory power of flexible staybolt ball 5, be moved forward and backward flexible staybolt ball 5 can only, flexible staybolt ball
When 5 forward movement, all faggings 4 are collapsed, and when flexible staybolt ball 5 moves backward, fagging 4 is opened.
The inside of handle 1 is equipped with lithium battery 9, and handle 1 offers battery installing port, battery peace far from one end of fagging 4
Sealing plate 10 is hinged on dress mouth, and sealing plate 10 and handle 1 are clamped, sealing plate 10 can be opened, convenient to carry out to lithium battery 9
The snap fit of replacement, sealing plate 10 is existing relatively conventional technology, and this will not be repeated here, pacifies on the lateral wall of handle 1
Equipped with control button 8, the input terminal of driving motor 2 is electrically connected by control button 8 with the output end of lithium battery 9, passes through control
Button 8 controls the positive and negative rotation of driving motor 2, this technology is equally operation common in the art, does not repeat them here, and drives
The three-phase motor that dynamic motor 2 selects specification suitable is, it can be achieved that different directions rotate.
The working principle of the utility model are as follows: when needing to strut the narrow opening of human body, pass through control button 8 and open and drive
Dynamic motor 2, threaded rod 3 rotates, and since flexible staybolt ball 5 is engaged with threaded rod 3, flexible staybolt ball 5 is moved forward, all faggings
4 gradually collapse, and then close power supply by control button 8, all faggings 4 are all protruded into narrow openings, control is then passed through
Button 8 makes driving motor 2 that threaded rod 3 be driven to rotate backward, and flexible staybolt ball 5 is one end movement to close handle 1, due to activity
The outer diameter of support ball 5 is greater than the internal diameter of the full circle formed when fagging 4 is closed, therefore flexible staybolt ball 5 can gradually support all faggings 4
It opens, opens the narrow openings of human body.
