AI Technical Summary
The bell-shaped glans seat connection structure of existing disposable circumcision staplers is prone to loosening under large tensile forces, leading to equipment instability and difficulty in disassembly and maintenance. Traditional connection methods such as threaded connections and welding have problems of insufficient connection strength and high cost.
The design employs a T-shaped clip and a T-shaped through slot for interlocking, combined with a locking sleeve and a retaining ring. It utilizes the automatic positioning of the spring and the lock head to achieve a high-strength connection between the pull rod and the glans cover. The connection is further strengthened and made more convenient by screwing the locking cap and the locking groove together.
It significantly improves the connection and fixation between the pull rod and the glans cover, with a maximum tensile force of 7000N, ensuring equipment stability, while facilitating installation and disassembly and reducing maintenance difficulty.

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.
[0022] As shown in the accompanying Figures 1-6The illustrated one clock type turtle head seat pull rod connection structure, including turtle head cover 1 and pull rod 2, the turtle head cover 1 is connected with pull rod 2, the bottom end of the turtle head cover 1 is fixedly connected with the bottom rod 12, the bottom of the bottom rod 12 is provided with T-shaped through slot 5, the top end of the pull rod 2 is provided with T-shaped clamp head 8, the T-shaped clamp head 8 is embedded with T-shaped through slot 5, the T-shaped clamp head 8 is connected with T-shaped through slot 5, the locking sleeve 3 is rotatably sleeved on the connecting and matching part of T-shaped clamp head 8 and T-shaped through slot 5, and the bottom end of the pull rod 2 is provided with a screw head 4.
[0023] In specific implementation, the T-shaped clamp head 8 at the top end of the pull rod 2 can be directly embedded in the T-shaped through slot 5 formed in the bottom rod 12 at the bottom of the turtle head cover 1, and the locking sleeve 3 is tightened, which can improve the connection and fixation of the pull rod 2 and the turtle head cover 1, and is convenient to disassemble and assemble, and is fixed firmly. With this fixing method, compared with the traditional connection structure, it can bear greater tension, and the maximum tension that the structure can bear is up to 7000N when in use.
[0024] The diameter of the pull rod 2 is smaller than the diameter of the bottom rod 12, the top end of the pull rod 2 is provided with a stop ring 7, the locking sleeve 3 is sleeved on the pull rod 2, and the locking sleeve 3 is rotatably sleeved on the bottom rod 12 by the stop ring 7.
[0025] In specific implementation, the diameter of the pull rod 2 is smaller than the diameter of the bottom rod 12, so that the locking sleeve 3 sleeved on the pull rod 2 can slide on the pull rod 2 at will, and is blocked by the stop ring 7. When the locking sleeve 3 is rotatably sleeved on the bottom rod 12, the bottom rod 12 can be pulled down under the blocking of the stop ring 7, thereby improving the connection firmness between the pull rod 2 and the bottom rod 12.
[0026] The top end of the T-shaped clamp head 8 is provided with a cylindrical screw groove, a spring is placed inside the bottom end of the cylindrical screw groove, a bottom plate 11 is supported at the top end of the spring, a lock head 9 is coaxially fixedly connected on the bottom plate 11, a locking cap 10 is sleeved on the lock head 9, and the locking cap 10 is rotatably sleeved in the cylindrical screw groove.
[0027] In specific implementation, when the T-shaped clamp head 8 is slid into the T-shaped through slot 5, the inclined surface of the lock head 9 is subjected to pressure, so that the bottom plate 11 descends in the cylindrical screw groove and the spring is compressed. With the movement of the T-shaped clamp head 8, when the lock head 9 moves to the lock slot 6 position, the potential energy of the spring is released, so that the lock head 9 is inserted into the lock slot 6, thereby avoiding the inconvenience of controlling the moving position when the T-shaped clamp head 8 is embedded, so that the embedded position of the T-shaped clamp head 8 can be positioned, the pull rod 2 and the bottom rod 12 can be coaxial, the tension strength can be improved, and the locking sleeve 3 can be rotatably sleeved, thereby improving the convenience of installation.
[0028] The top end of the T-shaped through slot 5 is provided with a lock slot 6, and the lock head 9 is inserted into the lock slot 6.
