Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding products, in particular to a quick-install plug with good sealing performance. Background Art

[0002] A plug generally refers to a sealing head, which generally refers to a component used to seal the end of a container to isolate the media inside and outside it, also known as an end cover.

[0003] The prior art discloses a quick-install plug (CN219432765U) with good sealing performance, comprising a blocking block, a connecting plate installed on the top of the blocking block, and a sealing ring installed on the outside of the blocking block; a pressing plate, the pressing plate is hinged to the bottom of the inside of the blocking block, and pressing blocks are equidistantly installed on the side of the pressing plate away from each other; a pull rod, a guide block is installed on the bottom end of the pull rod extending into the inside of the blocking block, and a pull plate is installed on the top of the pull rod extending out of the top of the connecting plate, a connecting rod is installed at the bottom of the guide block, a baffle is installed at the bottom of the connecting rod, a limit block is installed on the outside of the pull rod, a spring is installed on the top of the limit block, the blocking block is made of rubber, and the pressing block is in extrusion contact with the inner wall of the blocking block.

[0004] After searching, it was found that when using the device, it is necessary to manually pull the pull plate to control the flow of air pressure. This method is very laborious for workers and requires constant attention, thus affecting work efficiency. In addition, the pull rod is pulled by a spring, and there are no relevant fixing measures for the pull rod to adjust the baffle. This results in the baffle pushing the pull rod in the opposite direction when encountering resistance, causing leakage, thereby affecting the sealing of the device, and thus not being very practical.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0029] The working principle is as follows: the blocking block 10 is connected to the fixed block 11, and the blocking block 14 is fixed by the fixing assembly. By setting the fixing assembly, the pressing block 20 is pressed to make the push plate 16 move in coordination, and the pressing block 20 pushes the fixing ring 15 to clamp the top fixed position of the blocking block 14, so that the blocking block 14 can be clamped inside the fixing block 11 and block the inner circle of the blocking block 10. The fixing block 14 of the fixing assembly is not affected by resistance, thereby ensuring the sealing of the device and enhancing the overall practicality of the device; by setting the blocking block 14, utilizing the movable setting between the blocking block 14 and the fixing block 11 and the blocking block 10, the injection molded product can be depressurized at any time, and can be taken at any time without manual observation and control, which saves time and effort. At the same time, when used in conjunction with the fixing assembly, it can effectively control the gas flow while improving work efficiency.

[0030] like Figure 2 As shown, the top inner side of the block 10 is provided with a thread, and the fixed block 11 is composed of a circular column and a threaded ring, the threaded ring is threadedly arranged on the top of the block 10, and a sealing sleeve 13 is fixedly arranged above the top surface of the circular column; Figure 2 and Figure 4 As shown, a T-shaped through cavity is opened on the inner side of the blocking block 10, a circular ring plate is fixedly arranged on the inner side of the bottom of the T-shaped through cavity, the blocking block 14 is composed of a cylinder and a nail-shaped column, a sealing ring 21 is fixedly arranged on the upper end curved surface of the cylinder, the blocking block 14 is clamped to the circular ring plate through the cylinder, and the blocking block 14 is clamped to the T-shaped through cavity and the sealing sleeve 13 through the nail-shaped column.

[0031] The working principle is as follows: the fixed block 11 is threadedly arranged above the blocking block 10; the blocking block 10 seals the pipeline or injection molded product through the sealing ring 12; and the interior of the blocking block 10 utilizes the nail-shaped column of the blocking block 14 to clamp the T-shaped through cavity; the top diameter of the blocking block 14 is less than or equal to the sealing sleeve 13, so the sealing sleeve 13 seals between the blocking block 14 and the fixed block 11; the cylinder of the blocking block 14 is located below the nail-shaped column, and the diameter of the cylinder is smaller than the nail-shaped column, so the nail-shaped column and the internal circular ring plate of the blocking block 10 are sealed by the sealing ring 21, and the cylinder is clamped on the inner ring of the circular ring plate.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the inner part of the circular column of the fixed block 11 is symmetrically provided with a built-in cavity 24, the top of the circular column is symmetrically provided with a slideway 23 and a trapezoidal slideway 25, the slideway 23 and the trapezoidal slideway 25 are located directly above the built-in cavity 24, and the inner part of the curved surface of the circular column is symmetrically provided with nail-shaped circular holes, which form a cross-shaped through cavity with the built-in cavity 24; Figure 1 , Figure 3 and Figure 5 As shown, the pressing block 20 is composed of a large cylinder and a small cylinder. A sliding column 19 is fixedly arranged on the curved surface of the large cylinder. The sliding column 19 slides in the slideway 23. The small cylinder is fixedly arranged between the large cylinder and the fixing ring 15. The pressing block 20 slides in the nail-shaped circular hole. A buffer spring 18 is fixedly arranged between the large cylinder and the nail-shaped circular hole. The pressing block 20 is elastically connected to the built-in cavity 24 through the buffer spring 18; Figure 2 , Figure 3 and Figure 5 As shown, a trapezoidal block is provided on the top surface of the push plate 16, and the trapezoidal block slides in the trapezoidal slide 25. An R-shaped slot and a strip hole are opened inside the push plate 16, and the slide column 19 slides on the R-shaped slot. A fixed column 22 is fixedly provided on the inner wall surface of the built-in cavity 24, and a tension spring 17 is fixedly provided between the fixed column 22 and the top end of the strip hole. The push plate 16 is elastically connected to the fixed column 22 through the tension spring 17.

[0033] The working principle is as follows: the nail-shaped circular hole is divided into a large circular hole and a small circular hole, the large circular hole and the small circular hole are symmetrically arranged with the same built-in cavity 24 as the symmetry point, the small circular hole is located in the inner circle of the fixed block 11, and the large circular hole is located in the outer circle of the fixed block 11. The large cylinder of the pressing block 20 slides in the large circular hole, and the small cylinder of the pressing block 20 slides in the small circular hole. The buffer spring 18 is arranged between the large cylinder and the inner wall of the built-in cavity 24. Through the cooperation of the buffer spring 18, the large cylinder of the pressing block 20 can squeeze the buffer spring 18 to make the small cylinder slide in the small circular hole, thereby The cylinder can push the fixed ring 15 inward; while the trapezoidal block slides in the trapezoidal slideway 25, the push plate 16 is clamped with the trapezoidal slideway 25 by the shape of the trapezoidal block, thereby preventing the push plate 16 from falling. A short column is arranged at the top of the strip hole, and a tension spring 17 is fixedly arranged between the short column and the fixed column 22. When in use, the trapezoidal block is pushed to squeeze the push plate 16 toward the fixed column 22. With the cooperation of the tension spring 17, the slide column 19 can slide out of the R-shaped notch, the pressing block 20 can be pushed out, and the fixed ring 15 can release the stopper 14.

[0034] like Figure 2 and Figure 3As shown, the top surface of the nail-shaped column of the stopper 14 is symmetrically provided with semicircular grooves, a strip for lifting is formed between the two semicircular grooves, two circles of arc-shaped ring openings are provided on the upper curved surface of the nail-shaped column, the fixing ring 15 is a C-shaped ring, the inner side of the fixing ring 15 is arc-shaped, and the fixing ring 15 is clamped on the arc-shaped ring opening of the stopper 14.

[0035] The specific implementation is as follows: the block 10 is pressed and fixed to the injection molded product, and then the fixing block 11 is tightened and fixed to the block 10, and then the trapezoidal blocks on both sides of the fixing block 11 are pushed, and the trapezoidal blocks with push plates 16 squeeze the tension spring 17 toward the position of the fixing column 22. At this time, the sliding column 19 slides out along the R-shaped groove and the slideway 23. At this time, the pressing block 20 is in the ejection state, and the block 14 is pressed and pushed into the fixing block 11. The block 14 passes through the inner ring of the sealing sleeve 13, and the cylinder at the bottom of the block 14 is clamped in the annular plate. The sealing ring 21 blocks the gap between the cylinder and the annular plate, and the sealing sleeve 13 seals the gap between the fixing block 11 and the top of the nail-shaped column of the block 14 At this time, the pressing blocks 20 on both sides are pressed, and the movement of the pressing blocks 20 drives the sliding column 19 to slide in the R-shaped notch and the slideway 23. When the sliding column 19 reaches the bottom end of the R-shaped notch, it is locked in the position by the shape of the R-shaped notch. At the same time, the movement of the pressing block 20 synchronously pushes the fixing ring 15 to clamp the arc-shaped ring opening of the stopper 14. When the fixing ring 15 clamps the arc-shaped ring opening, the stopper 14 is fixed; when pressure relief is required, the trapezoidal clamping block is moved to slide on the trapezoidal slideway 25. When the trapezoidal slider approaches the slideway 23, the push plate 16 synchronously squeezes the tension spring 17 in the direction of the fixed column 22, and the sliding column 19 slides out along the R-shaped notch and the slideway 23 to achieve reset.
