[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 , the utility model provides a technical solution:

[0021] A pipe sleeve fool-proof mechanism for plastic products, comprising a mold 1, wherein the mold 1 is symmetrically provided with a circular hole 4 for installing the pipe sleeve, wherein a plug rod 15 for supporting the pipe sleeve is provided in the circular hole 4, and a dynamic seal is provided between the plug rod 15 and the circular hole 4 to prevent air leakage at the plug rod 15; an annular groove 5 is provided at the bottom of the circular hole 4, wherein a countersunk groove 17 is provided in the annular groove 5, wherein air holes 16 are symmetrically provided in the countersunk groove 17, wherein an air guide tube 2 is provided at one end of the air guide tube 2, wherein an air volume detection device body 3 is provided (and the air volume detection device body 3 comprises an air flow detector, a processor, a controller, an air pump and an alarm, wherein the air flow detector detects whether there is air flow in the air hole 16, then processes the air through the processor, and finally controls the alarm to sound an alarm through the controller, i.e., there is air flow in the air hole 16 If there is no airflow in the air hole 16, it means that the sleeve is installed incorrectly and the alarm will sound. If there is no airflow in the air hole 16, it means that the sleeve is installed correctly and the alarm will not sound. It can be used to warn workers whether the sleeve is installed correctly; it is a prior art), an annular plate 7 matching the annular groove 5 is provided on the outer wall of the air guide tube 2, and a fixing block 8 is symmetrically provided on the outer wall of the annular plate 7. A rectangular cavity 14 is provided in the fixing block 8, and a fixing piece is provided in the rectangular cavity 14, and a fixing groove is provided on the inner wall of the annular groove 5 to match the fixing block 8; through the use of the fixing piece, it is convenient to fix the air guide tube 2, and avoid the phenomenon that the air guide tube 2 and the countersunk groove 17 are separated when the gas in the air hole 16 is detected, which is conducive to detecting whether the sleeve is installed correctly, avoiding incorrect installation of the sleeve, and facilitating the installation of the sleeve.

[0022] In the utility model, the fixing member includes a movable plate 9 slidably arranged in a rectangular cavity 14 and an extrusion spring 10 arranged on one side of the movable plate 9, which is used to squeeze the movable plate 9, thereby squeezing the fixing rod 13 to fix the air guide tube 2; a fixing rod 13 is provided on one side of the movable plate 9, and a fixing hole (not shown in the figure) is provided on the inner wall of the fixing groove to cooperate with the fixing rod 13, a lever 12 is provided on the movable plate 9, and a rectangular quick opening 11 is provided on the fixing block 8 to cooperate with the lever 12.

[0023] In the utility model, a rubber nozzle 6 that cooperates with the air guide tube 2 is provided at one end of the annular plate 7. The rubber nozzle 6 is used in cooperation to improve the sealing between the air guide tube 2 and the countersunk groove 17, and prevent gas from flowing in from the bottom of the countersunk groove 17, thereby improving the accuracy of the tube sleeve detection; the top of the rubber nozzle 6 is inclined, which facilitates the rubber nozzle 6 to be inserted into the countersunk groove 17; and the rubber nozzle 6 is made of flexible rubber material.

[0024] In the utility model, an annular sealing gasket is provided on the annular plate 7, and an annular sealing groove is provided on the annular groove 5 to cooperate with the annular sealing gasket, so as to improve the sealing between the annular plate 7 and the annular groove 5 and avoid air leakage, thereby improving the accuracy of the pipe sleeve detection (the annular sealing gasket and the annular sealing groove are not shown in the figure).

[0025] Working principle: The utility model first installs the pipe sleeve on the insertion rod 15 of the mold 1, and then inserts the air guide pipe 2 connected to the air volume detection device body 3 into the bottom of the countersunk groove 17. Specifically, the two levers 12 are first twisted, and the movable plate 9 is driven to move by the levers 12, and then the fixed rod 13 is driven to move, so that the fixed rod 13 moves into the rectangular cavity 14. When the annular plate 7 enters the annular groove 5, the lever 12 is released, and then the fixed rod 13 is inserted into the fixed hole under the action of the extrusion spring 10 to achieve the fixation of the air guide pipe 2;

[0026] Then turn on the vacuum pump of the gas volume detection equipment body 3. When the pipe sleeve is installed incorrectly, external gas can enter the countersunk groove 17 through the air hole 16, and then enter the rubber mouth 6 through the countersunk groove 17, and finally enter the gas volume detection equipment body 3 through the air guide tube 2. When the gas volume detection equipment body 3 detects airflow, an alarm will be triggered to remind the staff that the pipe sleeve is installed incorrectly. When the pipe sleeve is installed correctly, under the action of the vacuum pump, the pipe sleeve will block the air hole 16, and no airflow will enter the gas volume detection equipment body 3, and no alarm will be triggered, indicating that the pipe sleeve is installed correctly.

[0027] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
