Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment processing, in particular to an auxiliary device for assembling a sealing ring of a flushing device control valve. Background Art

[0002] like Figure 1-2 The figure shows a medical flusher, which includes an upper body, a lower body, a flushing cap, and a push rod. A spring is provided at one end of the push rod, and a sealing ring is sleeved on the other end of the push rod. When installing the sealing ring, the sealing ring needs to cooperate with the lower body to achieve a sealing effect, so the sealing ring is protruding outward at one end of the push rod. Therefore, if the sealing ring is installed on the push rod in advance, the push rod will not be able to be installed in the lower body due to the protruding sealing ring. Therefore, one end of the push rod can only be sleeved with the spring and then installed in the flushing cap, and then the other end of the push rod is installed in the lower body without the sealing ring, and then the sealing ring is installed on the push rod on the other side of the lower body. After the sealing ring is installed, the upper body is finally installed on the lower body.

[0003] The existing problem is that when installing the sealing ring, the staff has to install it manually. They need to put the lower body on the push rod without the sealing ring, and then press the lower body with one hand to compress the spring, and expose one end of the push rod for installing the sealing ring to the outside, and then install the sealing ring with the other hand. However, this installation method has low work efficiency. During the entire installation process, the staff needs to manually press the lower body all the time. Long-term work consumes a lot of physical energy for the staff, causing arm soreness, which also affects the installation efficiency.

[0004] Therefore, there is an urgent need for an auxiliary device for assembling the sealing ring of the flusher control valve to reduce the labor intensity during installation and improve the installation efficiency of the sealing ring. Utility Model Content

[0034] See attached Figure 1-2 The figure shows the main structure of the flusher, including an upper body 1 and a lower body 2. The lower body 2 is provided with two main pipes, a connecting beam 7 is provided between the two main pipes, a push rod 4 is provided in each main pipe, a sealing ring 6 is provided at one end of the push rod 4, and a spring 5 is provided at the other end of the push rod 4. A flushing cap 3 is mounted on the spring 5, and the spring 5 exerts an outward thrust on the flushing cap 3.

[0035] See attached Figure 3-7The auxiliary device for assembling the sealing ring of the flusher control valve shown in the figure comprises a base 8, a slide rail 11 is installed by bolts in the middle part of the base 8 along the length direction, a slider 12 is slidably matched on the slide rail 11, a mounting seat 13 is bolted on the slider 12, two mounting holes 16 are provided on the mounting seat 13, a first fixed plate 14 and a second fixed plate 15 are respectively installed on the mounting seat 13 through the mounting holes 16, the positions of the first fixed plate 14 and the second fixed plate 15 on the mounting seat 13 correspond to the positions of the flushing cap 3 on the flusher, when installing the sealing ring 6, the flushing cap 3 with the spring 5 and the push rod 4 are respectively placed on the first fixed plate 14 and the second fixed plate 15, the flushing cap 3 is limited and fixed by the first fixed plate 14 and the second fixed plate 15 to prevent the flushing cap 3 from sliding off the mounting seat 13 during installation, the first fixed plate 14 and the second fixed plate 15 are provided with mounting columns 17 at the positions corresponding to the mounting holes 16, and by installing The plug-in cooperation of the column 17 and the mounting hole 16 realizes the installation of the first fixing plate 14 and the second fixing plate 15 on the mounting seat 13. The base 8 is located at one end of the slide rail 11 and is installed with a pressure arm 9 by bolts. One end of the pressure arm 9 is provided with a pressure rod 10. When installing the sealing ring 6, the flushing cap 3 with the push rod 4 is placed in the first fixing plate 14 and the second fixing plate 15 respectively, and then the lower body 2 is put on the two push rods 4 through the main pipe sleeve, and then slides to the bottom of the pressure rod 10 through the slide rail 11. At this time, the pressure rod 10 is used to replace manpower to press the lower body 2 to expose one end of the two push rods 4 for easy installation. It can be seen that the pressure rod 10 replaces manpower to free the hands of the staff, so that the staff does not need to press the lower body 2 for a long time, thereby saving physical strength and reducing labor intensity. At the same time, the staff can better install the sealing ring 6 with the cooperation of both hands, thereby improving the efficiency of installation.

[0036] As an auxiliary device for assembling the sealing ring 6 of the flusher control valve, in order to prevent the lower body 2 from sliding outward along the slide rail 11 during the installation process, a positioning hole is opened at the end of the pressure rod 10, and a positioning mechanism is provided at the position of the pressure rod 10 at the positioning hole. The positioning mechanism specifically includes a guide sleeve 20 fixedly arranged on the pressure rod 10, and a positioning pin 21 is arranged in the guide sleeve 20. The positioning pin 21 is concentric with the positioning hole. At the same time, a magnetic block 26 is embedded in the position of the pressure rod 10 at the positioning hole, and a suction block 25 is arranged at the position of the positioning pin 21 near the magnetic block 26.

At the same time, a travel hole 22 is opened in the guide sleeve 20 along the length direction, and a bayonet 23 is transversely provided at one end of the travel hole 22. A driving column 24 is provided in the travel hole 22, and the positioning pin 21 is controlled by the driving column 24 to extend and retract up and down in the positioning hole. When the sealing ring 6 is installed and the lower body 2 is located below the pressure rod 10, the driving column 24 is separated from the bayonet 23. At this time, the positioning pin 21 is quickly inserted into the positioning hole under the adsorption action of the magnetic block 26 and the suction block 25. At this time, the positioning pin 21 is located at the front end of the connecting beam 7 of the lower body 2. In this way, the positioning pin 21 is used to limit the lower body 2 to prevent it from sliding backwards.

[0037] As an auxiliary device for assembling the sealing ring of the flusher control valve, in order to enable the positioning pin 21 to accurately limit the lower body 2, the base 8 is located on both sides of the slide rail 11 and is provided with a second baffle 19 at one end close to the pressure arm 9.

The introduction portion 27 increases the entry angle of the lower main body 2 when sliding to the bottom of the pressure rod 10, thereby reducing the probability of collision between the lower main body 2 and the pressure rod 10.

[0040] Please refer to the attached Figure 8As shown, first, the mounting seat 13 equipped with the first fixed plate 14 and the second fixed plate 15 is slid out from the bottom of the pressure rod 10 along the slide rail 11, and then the two flushing caps 3 are placed in the first fixed plate 14 and the second fixed plate 15, and then the spring 5 and the push rod 4 are placed in the flushing cap 3, and then the lower body 2 is correspondingly mounted on the two push rods 4, and then the lower body 2 is pressed. At this time, the spring 5 is compressed by the lower body 2, and then the entire lower body 2 is slid to the bottom of the pressure rod 10 through the slide rail 11 and one end of the slider 12 is pressed against It is connected to the second baffle 19, and then the pressure rod 10 is pressed just on the connecting beam 7 of the lower main body 2. At this time, one end of the two push rods 4 is just exposed from the lower main body 2. Then the positioning pin 21 is passed through the positioning hole and blocked at the front end of the connecting beam 7 for limiting. Then the staff can install the sealing ring 6 on the two push rods 4. After the sealing ring 6 is installed, the entire lower main body 2 is moved out from under the pressure rod 10. At this time, the lower main body 2 rebounds rapidly under the reverse elastic force of the spring 5, and the sealing ring 6 is just stuck in the lower main body 2 to achieve sealing.
