Description

Technical Field

[0001] This utility model relates to the field of melt pressure sensor technology, and in particular to a melt pressure sensor with a rigid rod and flexible tube structure. Background Technology

[0002] A melt pressure sensor is a device used to measure and control the pressure of molten substances under high-temperature conditions. It mainly utilizes the pressure of the medium acting directly on the diaphragm of the sensor. With the development of technology, melt pressure sensors with rigid rods and flexible tubes have been developed.

[0003] In existing melt pressure sensors, the rigid rod, flexible tube, and housing are threaded together during installation. However, when the sensor is stored, the rigid rod, flexible tube, and housing are separated. If the sensor is not installed for a long time, one of the three components may be lost. Therefore, a melt pressure sensor with an auxiliary connection is needed to prevent loss when the melt sensor is not installed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a melt pressure sensor with a rigid rod and flexible tube structure, comprising:

[0007] A melt sensing assembly, comprising a housing and a flexible tube; the flexible tube is threadedly connected to the bottom end of the housing;

[0008] An auxiliary connection assembly includes a connecting ring, a fixing plate, a magnetic ring, and a snap-fit ​​ring. The connecting ring is fixed to the lower end of the flexible tube, the fixing plate is fixed to the lower side of one side of the housing, the magnetic ring is fixed to the top side of the fixing plate, the connecting ring is attracted to the inner side of the magnetic ring, and the snap-fit ​​ring is located on the other side of the housing. The snap-fit ​​rings are arranged in a set.

[0009] Furthermore, the fixing plate has a plug hole at the connection with the magnetic ring, and the plug hole is engaged with the lower end of the flexible tube.

[0010] Furthermore, a fixing rod is fixedly connected to the upper and lower sides of the other side of the housing, and an installation rod is fixedly connected to the inner end of the snap ring, with the installation rod and the fixing rod being threadedly connected.

[0011] Furthermore, the melt sensing assembly also includes a rigid rod; the rigid rod is threaded to the bottom end of the flexible tube.

[0012] Furthermore, it also includes limiting components;

[0013] The limiting component includes a connecting frame, mounting holes, and plug-in plates; the connecting frame is fixed to the upper and lower sides of one side of the housing, and the connecting frame is arranged in a set. The mounting holes are opened on the outer end surface of the connecting frame, and the two ends of the plug-in plates are inserted into the inner sides of the adjacent mounting holes.

[0014] Furthermore, the connecting frame is located outside the fixed rod, and a magnetic block is fixedly connected to the inner side of the arc-shaped plug plate. The magnetic block is engaged with the opening of the snap ring, and the magnetic block is attracted to the surface of the rigid rod.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, by setting an auxiliary connection component, allows the bottom end of the flexible tube to be inserted into the fixed plate when the melt sensor is in a separated state, so that the connecting ring at the lower end of the flexible tube is attracted to the magnetic ring, and then the rigid rod is engaged with the snap ring, thereby limiting the rigid rod and realizing the connection between the shell, the flexible tube and the rigid rod, thus avoiding the loss of any of the three components.

[0017] Second, based on the first beneficial effect, by setting a limiting component, when the rigid rod is engaged with the snap ring, the plug plate is inserted into the mounting hole of the connecting frame, so that the magnetic block at the arc of the plug plate is engaged with the opening of the snap ring, and the magnetic block is attracted to the rigid rod, thereby further limiting the rigid rod after engagement and preventing the rigid rod from separating from the snap ring.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-5 As shown, this embodiment is a melt pressure sensor with a rigid rod and flexible tube structure, including:

[0031] A melt sensing assembly includes a housing 11 and a flexible tube 12; the flexible tube 12 is threaded to the bottom end of the housing 11.

[0032] The melt sensing assembly also includes a rigid rod 13; the rigid rod 13 is threaded to the bottom end of the flexible tube 12;

[0033] Electronic components are housed inside the housing 11, the flexible tube 12 serves as an isolation and protection mechanism, and the rigid rod 13 is the rigid part of the sensor used to transmit pressure.

[0034] The auxiliary connection assembly includes a connecting ring 21, a fixing plate 22, a magnetic ring 23, and a snap-fit ​​ring 26. The connecting ring 21 is fixed to the lower end of the flexible tube 12, the fixing plate 22 is fixed to the lower side of one side of the housing 11, the magnetic ring 23 is fixed to the top side of the fixing plate 22, the connecting ring 21 and the inner side of the magnetic ring 23 are attracted to each other, and the snap-fit ​​ring 26 is located on the other side of the housing 11. The snap-fit ​​ring 26 is arranged in a set.

[0035] The connecting ring 21 is used to connect the bottom end of the flexible tube 12 to the fixing plate 22. The fixing plate 22 is used to connect the magnetic ring 23. The magnetic ring 23 is used to attract the connecting ring 21, thereby limiting the flexible tube 12 after insertion. The snap ring 26 is used to snap the rigid rod 13. The snap ring 26 is made of PVC board and has toughness.

[0036] The fixing plate 22 has a plug hole 221 at the connection with the magnetic ring 23, and the plug hole 221 is engaged with the lower end of the flexible tube 12.

[0037] A fixing rod 24 is fixedly connected to the upper and lower sides of the other side of the housing 11, and an installation rod 25 is fixedly connected to the inner end of the snap ring 26. The installation rod 25 is threadedly connected to the fixing rod 24.

[0038] The insertion hole 221 is used for the connection between the lower end of the flexible tube 12 and the fixed plate 22. The fixed rod 24 and the mounting rod 25 are used together for the connection between the snap ring 26 and the housing 11. In use, the top end of the flexible tube 12 is threaded to the bottom end of the housing 11, and the bottom end of the flexible tube 12 is inserted into the insertion hole 221, so that the flexible tube 12 drives the connecting ring 21 to be attracted to the inner side of the magnetic ring 23, thereby limiting the flexible tube 12 after insertion. When installing the snap ring 26, the mounting rod 25 is aligned with the fixed rod 24, the two are inserted, and the mounting rod 25 is rotated so that the snap ring 26 is connected to the housing 11 through the mounting rod 25 and the fixed rod 24.

[0039] Working principle: When the sensor is not installed, the housing 11, flexible tube 12, and rigid rod 13 are in a separate state. When using the assembly, hold the flexible tube 12 and thread the top end of the flexible tube 12 to the bottom end of the housing 11. Insert the bottom end of the flexible tube 12 into the insertion hole 221, so that the flexible tube 12 drives the connecting ring 21 to attract the inner side of the magnetic ring 23, thereby limiting the insertion of the flexible tube 12. Hold the rigid rod 13 and align the rigid rod 13 with the snap ring 26. Push the rigid rod 13 to... The rigid rod 13 presses against the opening of the snap ring 26. Since the snap ring 26 is made of PVC board, it is flexible and allows the rigid rod 13 to snap into the snap ring 26, causing the snap ring 26 to limit the rigid rod 13, thereby realizing the connection between the housing 11, the flexible tube 12 and the rigid rod 13. When the snap ring 26 is replaced, the snap ring 26 is rotated, which causes the snap ring 26 to drive the mounting rod 25 to rotate, so that the mounting rod 25 is rotated and separated from the fixing rod 24 through the thread, thereby facilitating the replacement of the new snap ring 26.

[0040] The above steps, through the interaction between the magnetic ring 23 and the connecting ring 21, can limit the position of the inserted flexible tube 12.

[0041] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, further includes:

[0042] Limiting components;

[0043] The limiting component includes a connecting frame 31, mounting holes 32 and a plug plate 33; the connecting frame 31 is fixed on the upper and lower sides of one side of the housing 11, and the connecting frame 31 is set in a group; the mounting holes 32 are opened on the outer end surface of the connecting frame 31, and the two ends of the plug plate 33 are inserted into the inner side of the adjacent mounting holes 32.

[0044] The connecting bracket 31 is used to open the mounting hole 32, which is used for the insertion of the two ends of the inner side of the plug plate 33. The plug plate 33 is used for the connection of the magnetic block 34.

[0045] The connecting frame 31 is located outside the fixed rod 24. A magnetic block 34 is fixedly connected to the inner side of the arc of the plug plate 33. The magnetic block 34 is engaged with the opening of the snap ring 26 and the magnetic block 34 is attracted to the surface of the rigid rod 13.

[0046] The magnetic block 34 is used to connect the rigid rod 13 and the plug plate 33. The magnetic block 34 is attracted to the surface of the rigid rod 13 by magnetic force, and the magnetic block 34 and the plug plate 33 further limit the rigid rod 13 after it is snapped together.

[0047] Working principle: After the rigid rod 13 is engaged with the snap ring 26, hold the plug plate 33 by hand and insert both ends of the inner side of the plug plate 33 into the mounting holes 32, so that the magnetic block 34 at the arc of the plug plate 33 is engaged with the opening of the snap ring 26, and the magnetic block 34 is attracted to the rigid rod 13 by magnetic force, thereby further limiting the rigid rod 13 after engagement and preventing the rigid rod 13 from separating from the snap ring 26;

[0048] The above steps can improve its functionality.
