Artificial limbs are artificial prostheses, also called "artificial limbs", which are specially designed and assembled to compensate for amputees or incomplete limb defects. It is mainly used for replacing partial function of the lost limb, and recovering a certain self-care and working ability of the amputee. The suitable object is amputee caused by diseases, traffic accidents, industrial accidents, sports injuries and the like. The artificial limb is connected with the stump, in order to protect the stump, a silica gel sleeve is sleeved on the stump, a hard supporting tray is arranged inside the top end of the silica gel sleeve, a port connected with a screw rod is arranged on the tray, the other end of the screw rod is connected with a connecting mechanism, the connecting mechanism is connected with the artificial limb, the hard sleeve is an outer protective shell of the stump silica gel sleeve, a connecting piece on the artificial limb is provided with a base body, a straight gear connected with a one-way valve is arranged in the base body, the straight gear on the one-way valve can only rotate towards one direction and cannot rotate in the reverse direction, a spring is arranged inside the base body, the straight gear can be stretched forwards when being pressed down and reset when not being pressed down, the straight gear is stretched forwards when being installed, the screw rod is inserted into the base body to be in place, the straight gear is loosened to reset to be connected with the screw rod for realizing locking, but when the straight gear is locked with a thread matching structure, the straight gear of the one-way valve and the connecting rod at the upper part are pulled to burn and seized and can be separated from the connecting rod only by external force and a damage apparatus, the locking buckle is loosened in single locking, and if the connecting part is loosened, additional burden is brought to a patient.
Disclosure of Invention
In order to solve the problem that the existing connecting structure is easy to block, the invention provides a connecting structure of a residual limb silica gel sleeve connecting rod and an artificial limb connecting piece, which can realize reliable locking and can not block.
The technical scheme is as follows: the utility model provides a connection structure of incomplete limb silica gel cover connecting rod and artificial limb connecting piece, it includes pedestal and screw rod, be provided with in the pedestal with screw rod complex straight-teeth gear, the check valve is connected to the straight-teeth gear, a serial communication port, the pedestal includes upper base body and lower pedestal, the gear be the straight-teeth gear and set up in the upper base body, the screw rod runs through the upper base body and stretch into in the lower pedestal, be provided with down in the pedestal and be located the locking semi-ring of screw rod both sides, the driver is connected to the locking ring, the screw rod passes through locking ring locking is first fixed point, the straight-teeth gear with the screw rod locking is the second fixed point.
The locking device is further characterized in that the locking ring is arranged on a locking seat, and the locking seat is connected with a driving switch and a reset gas spring;
the locking semi-ring is arranged on the inner side of the lower part of the locking seat, an arc-shaped groove is formed in the inner side of the upper end of the locking seat, an annular locking piece matched with the arc-shaped grooves on the two sides is arranged on the driving switch, and one end of the annular locking piece is connected with the driving switch exposed out of the seat body;
the annular locking piece other end is provided with the guide bar, be provided with in the pedestal with guide bar complex guide way.
After the invention is adopted, the straight gear on the one-way valve is designed into a reverse bevel gear, so that the straight gear has a certain inclination as a disengaging guide when being pushed, the clearance eliminating effect can be realized due to the inclination locking relation when being locked, a group of locking half rings are additionally arranged to buckle the screw rod to increase the bearing capacity of the connector so as to disperse the bearing gravity point of the connector, and the bearing area is increased because the two locking half rings are combined into a whole circle to tightly clasp the screw rod, so that the problems of single-point locking of the one-way valve and the gear at the upper part and possible locking and blocking of the buckle are eliminated.

FIG. 2 is a top view of the bevel gear in preparation for screw insertion;
FIG. 3 is a schematic structural view of the locking half ring;
FIG. 4 is a schematic view of the open state of the locking half rings;
fig. 5 is a schematic view of the locking state of the locking half rings.
Detailed Description
Referring to fig. 1 to 3, the connecting structure of the residual limb silica gel sleeve connecting rod and the artificial limb connecting piece comprises a base body and a screw rod 1, wherein the base body comprises an upper base body 2 and a lower base body 4, a bevel gear 3 matched with the screw rod 1 is arranged in the upper base body 2, the bevel gear 3 is connected with a one-way valve 9, the screw rod 1 penetrates through the upper base body 2 and extends into the lower base body 4, locking semi-rings 10 positioned at two sides of the screw rod 1 are arranged in the lower base body 4, the locking semi-rings 10 are installed on a locking base 6, the locking base 6 is connected with a driving switch 8 and a reset air spring 7, the screw rod 1 is locked into a first fixing point through the locking semi-rings 10, and the bevel gear 3.
Specifically, locking semi-ring 10 sets up in the inboard of 6 lower parts of locking seat, and 6 upper ends of locking seat establish the inboard and be provided with the arc wall, be provided with on the drive switch 8 with the arc wall complex annular latch fitting 5 of both sides, and the drive switch 8 that exposes in the pedestal is connected to annular latch fitting 5 one end, and the annular latch fitting 5 other end is provided with guide bar 11, is provided with in the lower pedestal 4 with guide bar 11 complex guide way.
The working principle is as follows: when the screw rod is installed, drive switch 8 is pulled up 90 degrees earlier, annular latch fitting 5 is being pulled and is moving toward drive switch 8 direction, annular latch fitting 5 leaves the arc wall and pushes up locking seat 6 toward both sides, two locking semi-rings 10 separate, pressing check valve 9, make bevel gear 3 ejecting forward, insert the screw rod in place, loosen check valve 9, bevel gear 3 resets and realizes the protection for the first time with screw rod 1 locking, reset drive switch 8 and annular latch fitting 5, let locking seat 6 also follow to reset under the effect of air spring 7, two locking semi-rings 10 close and pin screw rod 1, form the secondary protection.
