[0018] The utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) The utility model provides a tubular connector with a healthy belly plate, which is provided with a clamping assembly and a rotating reset assembly at one end of the connecting tube. When one end of the two handles on the healthy belly plate are respectively fixed to one end of the positioning tube and one end of the connecting tube, the connecting tube and the positioning tube can be docked after the connecting block is inserted into the inner side of the positioning tube through the cooperation of the clamping block and the clamping groove. When the connecting block is inserted, the direction of the clamping block on the side of the connecting block can be adjusted through the cooperation of the moving block, the rotating groove, the rotating block and the spring spring, so that the clamping block is located at the entrance of one end of the positioning tube opposite to the clamping groove. The cross-sectional shape extending from the inner side of the positioning tube is L-shaped. When the clamping block extends into the L-shaped connection, the reset force of the clockwork spring will cause the connecting block to drive the clamping block to return to its initial orientation, and then limit the clamping block to the inner side of the clamping slot, thereby improving the reliability of the connection, so that one end of the two handles are connected to each other by means of the tubular connecting piece. After being stored in a parallel state with the healthy belly plate, the healthy belly plate is lifted up.

DETAILED DESCRIPTION

[0027] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a tubular connector with a strong web includes: a positioning tube 1, a connecting tube 2, and a clamping assembly and a rotation reset assembly arranged at one end of the connecting tube 2.

[0029] The clamping assembly includes: a connecting block 3 arranged at one end of the connecting tube 2, a clamping block 31 fixed to the top of the connecting block 3 near one end, and a clamping groove 32 opened at one end of the positioning tube 1 facing the connecting tube 2; the cross-sectional shape of the clamping groove 32 extending toward the inner side of the positioning tube 1 is L-shaped.

[0030] It should be noted that the diameter of the connecting block 3 is the same as the inner diameter of the positioning tube 1, and the width of the clamping block 31 is the same as the width of the clamping slot 32; the connecting block 3 drives the clamping block 31 to rotate so that the clamping block 31 is located at the entrance of one end of the positioning tube 1 opposite to the clamping slot 32, and the connecting tube 2 is pushed to drive the connecting block 3 to extend into the inner side of the positioning tube 1, and the clamping block 31 extends into the inner side of the clamping slot 32. When the clamping block 31 extends into the L-shaped connection of the clamping slot 32, it drives the clamping block 31 to flip again, and the docking between the connecting tube 2 and the positioning tube 1 can be completed.

[0031] The rotation reset assembly includes: a moving block 4 sleeved on the inner side of the connecting tube 2 near one end, a rotation groove 41 provided at the end of the moving block 4 facing the connecting block 3, and a rotating block 42 fixed at the end of the connecting block 3 facing the rotation groove 41; a clockwork spring 43 is provided on the side of the rotating block 42 located inside the rotation groove 41.

[0032] It should be noted that the diameters of the connecting block 3 and the moving block 4 are the same as the inner diameter of the connecting tube 2; one end of the rotating block 42 is rotatably connected to the inner side of the rotating groove 41, one end of the spring 43 is fixed to the side of the rotating block 42, and the other end is fixed to the inner side of the rotating groove 41; the connecting block 3, the moving block 4 and the rotating block 42 are all coaxially arranged with the connecting tube 2; before the connecting block 3 extends into the inner side of the positioning tube 1, the rotating block 42 can be driven to rotate synchronously on the inner side of the rotating groove 41 by rotating the connecting block 3, and the spring 43 will be subjected to a rotational force along with the rotating block 42, and when the clamping block 31 enters the inner side of the clamping groove 32, the rotational force on the connecting block 3 can be cancelled, and when the clamping block 31 extends into the L-shaped connection of the clamping groove 32, the rotational force of the spring 43 is cancelled and reset to the initial state, which can drive the rotating block 42, the connecting block 3 and the clamping block 31 to flip upward, and then the clamping block 31 is limitedly clamped on the inner side of the clamping groove 32, thereby improving the reliability of the connection.

[0033] One end of the moving block 4 is provided with a moving reset assembly for moving the moving block 4 inside the connecting tube 2 and limiting its posture. The moving reset assembly includes: a plurality of reset springs 5 ​​fixed to one end of the moving block 4 facing the inside of the connecting tube 2, a slide groove 51 provided on the top of the connecting tube 2, and a shifting block 52 fixed on the top of the moving block 4; one end of the reset spring 5 is fixed to the inside of the connecting tube 2, and the side surface of the shifting block 52 is slidably connected to the inside of the slide groove 51.

[0034] It should be noted that, in the plane direction, the sum of the length of the shift block 52 and the length of the slot 32 is the same as the length of the slide slot 51; when the positions of the two connected ends are fixed, since it is impossible to directly drive the connecting tube 2, the connecting block 3 and the block 31 to move toward the positioning tube 1 and the slot 32, before the two connected ends are aligned, the shift block 52 can be shifted to drive the moving block 4 at the bottom to move along the length direction of the slot 51, so that the moving block 4 drives the rotating block 42 and the connecting block 3 to move toward the inside of the connecting tube, and squeezes a number of return springs 5 ​​to manually make up the distance between one end of the connecting block 3 and one end of the positioning tube 1. At the same time, after the two connected ends are aligned and the block 31 is docked to the inner side of the slot 32, the force applied to the shift block 52 can be cancelled, and the force applied by the moving block 4 to the return spring 5 can be cancelled. The return spring 5 can be reset, and the block 31 is automatically pushed into the slot 32, thereby improving the convenience and practicality of the tubular connector when used.

[0035] Example

[0036] like Figure 4As shown, one end of the positioning tube 1 and the connecting tube 2 is provided with a connecting groove 6, and an internal thread is provided inside the connecting groove 6. A belly plate grip 7 is provided inside the connecting groove 6 at one end of the positioning tube 1 and the connecting tube 2, and one end of the belly plate grip 7 is rotatably connected to a belly plate slider 8. One end of the belly plate grip 7 is connected to the inner thread of the connecting groove 6 through an internal thread.

[0037] It should be noted that, with the cooperation of the internal threads on the inner side of the connecting groove 6, it is convenient to install the positioning tube 1 and the connecting tube 2 on the two belly plate handles 7 respectively, which makes it easy to install and disassemble, and improves the convenience during use.

[0038] The specific working principle is that during the folding and storage of the abdominal plate, the two abdominal plate sliders 8 are aligned, the two abdominal plate handles 7 are respectively installed on the two abdominal plate handles 7 through the cooperation of the connecting groove 6 and the internal thread, and the two abdominal plate handles 7 are respectively flipped relative to each other, and the dial block 52 is driven to drive the moving block 4 at the bottom to move along the length direction of the slide groove 51, so that the moving block 4 drives the rotating block 42 and the connecting block 3 to move toward the inside of the connecting tube, and squeezes a number of reset springs 5 ​​to manually make up the distance between one end of the connecting block 3 and one end of the positioning tube 1, and aligns one end of the two abdominal plate handles 7 with each other and is parallel to the abdominal plate, and rotates the connecting block 3 to drive the rotating block 42 to rotate synchronously on the inner side of the rotating groove 41, and the clockwork spring 43 will be subjected to a rotational force along with the rotating block 42, so that the clamping block 31 is located opposite to the clamping groove 32. When the locking block 31 is inserted into the L-shaped connection of the locking groove 32, the rotation force of the spring 43 is cancelled and reset to the initial state, which can drive the rotating block 42, the connecting block 3 and the locking block 31 to flip upward, and then the locking block 31 is limited and connected to the inner side of the locking groove 32, so as to complete the docking between the connecting tube 2 and the positioning tube 1, so that one end of the two grips are connected to each other by the tubular connecting piece. After being stored in parallel with the abdominal plate, the abdominal plate is lifted up. Under the influence of shaking or gravity, the two grips will not be in a perpendicular state with the abdominal plate again under the action of the tubular connecting piece, thereby not affecting the folding and storage effect of the abdominal plate, thereby improving practicality.

[0039] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model.
