Its main function is to replace the lost part of the function of limbs, so that amputee can recover certain life self-care and working ability. The amputee is suitable for the patients with diseases, traffic accidents, industrial injuries, sports injuries and other reasons. The artificial limb is connected with the residual limb to be an important part, in order to protect the residual limb, a silica gel sleeve is sleeved on the residual limb, a hard supporting tray is arranged in the top end of the silica gel sleeve, an interface 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, a hard sleeve is an outer protective shell of the residual limb silica gel sleeve, a connecting piece on the artificial limb is provided with a seat body, a spur gear connected with a one-way valve member is arranged in the seat body, the spur gear on the one-way valve member can only rotate in one direction, can not rotate in the opposite direction, a spring is arranged in the spur gear, the spur gear can be forwards stretched when being pressed, and can be reset when not being pressed, the spur gear is firstly pressed to be forwards stretched when being pressed, after the screw rod is inserted into the seat body to be in place, the screw rod is loosened to enable the spur gear to be reset to be connected with the screw rod, but the contact point is too single when the screw rod is locked with a threaded matching structure on the screw rod, the connecting mechanism is easy to be blocked and can not be separated, the upper part of the spur gear and the connecting rod is enabled to be blocked by pulling and to be blocked by an external force, the spur gear and the connecting rod can only rotate in one direction, the spur gear can be rotated to rotate in one direction, and the spur gear can be released, if the spur gear can be loose, and the connecting part can be loose, and the patient can be loose, if the additional phenomenon is caused.
Disclosure of Invention
In order to solve the problem of easy blocking in the prior art, the invention provides a connecting structure of a residual limb silica gel sleeve connecting rod and a prosthetic limb connecting piece, which can realize reliable locking and can not cause blocking phenomenon.
The technical scheme is as follows: the utility model provides a connecting structure of incomplete limb silica gel cover connecting rod and artificial limb connecting piece, its includes pedestal and screw rod, be provided with in the pedestal with screw rod complex straight-tooth wheel, the check valve is connected to the straight-tooth wheel, its characterized in that, the pedestal includes pedestal and lower pedestal, the gear be the straight-tooth wheel and set up in the pedestal, the screw rod runs through the pedestal and stretches into in the lower pedestal, be provided with in the lower pedestal and be located the locking semi-ring of screw rod both sides, the locking ring is connected the driver, the screw rod passes through the locking ring locks to be first fixed point, the straight-tooth wheel with the screw rod locks to be the second fixed point.
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 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 other end of the annular lock piece is provided with a guide rod, and a guide groove matched with the guide rod is formed in the base body.
After the invention is adopted, the straight gear on the one-way valve is designed into a reverse bevel gear, so that a certain inclination is adopted as a disengaging guide when the straight gear is pushed, a clearance elimination effect can be realized when the straight gear is locked due to the inclination locking relation, a group of locking semi-rings are additionally added to buckle the screw rod to increase the bearing capacity of the connector so as to disperse the bearing point of the connector, and the two locking semi-rings are combined into a whole circle to buckle the screw rod, so that the bearing area is increased, and the problems of single-point locking of the upper part one-way valve and the gear and possible locking of the lock catch are eliminated.
