Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure sensors, in particular to a melt pressure sensor with a rigid rod structure. Background Art
[0002] A melt pressure sensor is an electronic device used to measure the pressure of molten materials under high-temperature conditions. The pressure of the medium directly acts on the sensor's diaphragm, causing it to undergo a micro-displacement proportional to the medium's pressure, thereby changing the sensor's resistance. The electronic circuit detects this change and converts it into a standard signal corresponding to the pressure. When in use, the melt pressure sensor is threaded into the hole where the measurement is required. This existing structural design generally requires fixed-hole installation, resulting in poor adaptability and hindering ease of use. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0030] The utility model provides a melt pressure sensor with a rigid rod structure. Through the mutual cooperation of the melt pressure sensor component, the mounting component and the limit locking component, the installed threaded sleeve can be freely replaced during use, and threaded sleeves of different specifications can be selected. In this way, it can be adapted to be installed in holes of different sizes, thereby improving the adaptability of use.
[0031] Figures 1-6 The figure shows the overall structure of a rigid rod structure melt pressure sensor of the utility model. Figure 1-6 The main structure of this embodiment includes: a melt pressure sensor assembly, a mounting assembly and a limit locking assembly.
[0032] The melt pressure sensor assembly is used in conjunction with the mounting assembly. Specifically, the melt pressure sensor assembly includes a melt pressure sensor body 11, a rigid rod 12, a detection end 13, and a hexagonal bolt 14.
[0033] During specific use, the wrench is fitted onto the hexagonal bolt 14 to achieve rotation of the rigid rod 12 , which in turn drives the threaded sleeve 21 to rotate and install.
[0034] The mounting assembly is used to cooperate with the limit locking assembly to complete the assembly and disassembly. Specifically, the mounting assembly includes an annular baffle 24 fixed to the surface of the rigid rod 12, a guide limit rod 25 connected to the annular baffle 24, a threaded sleeve 21 that fits the rigid rod 12, and a long slide groove 22 provided on the inner side of the threaded sleeve 21;
[0035] During actual use, the limiting locking assembly locks the threaded sleeve 21 to facilitate installation and disassembly.
[0036] The limiting locking assembly includes a limiting ring 31 provided at the front end of the threaded sleeve 21, a groove 32 provided at the front end of the guide limiting rod 25, a second threaded hole 33 provided on the top surface of the guide limiting rod 25, and a third threaded hole 34 provided on the side wall of the limiting ring 31;
[0037] During specific use, the melt pressure sensor body 11 is installed and used through the threaded sleeve 21. When the specification needs to be replaced, the user selects a threaded sleeve 21 of suitable specifications to fit with the rigid rod 12, and fits the long slide groove 22 with the guide limit rod 25, and directly moves the threaded sleeve 21 forward until the top of the threaded sleeve 21 contacts the annular baffle 24. At this time, the limit ring 31 is directly fitted into the groove mouth 32, so that the second threaded hole 33 and the third threaded hole 34 correspond to each other, and a threaded rod is used to pass through the second threaded hole 33 and the third threaded hole 34, so that they can be limited and locked, and the new threaded sleeve 21 is installed in place for the subsequent installation and use of the melt pressure sensor body 11.
[0038] Furthermore, the separation assembly is provided to facilitate the separation of the limit ring 31 and the threaded sleeve 21. This detachable structural design facilitates the replacement of the limit ring 31. When wear occurs, the limit ring 31 can be freely replaced, thereby reducing replacement costs.
[0039] Specifically, it also includes a separation assembly, which includes a first annular plate 41, a second annular plate 42 and a third annular plate 43 fixed to the outer wall of the limiting ring 31;
[0040] The first annular plate 41, the second annular plate 42 and the third annular plate 43 are provided with fourth threaded holes 44 of the same structure;
[0041] During actual use, the first annular plate 41, the second annular plate 42 and the third annular plate 43 are fitted with the threaded sleeve 21 and are locked by screws passing through the corresponding fourth threaded holes 44. Such an installation structure facilitates the replacement of the limit ring 31 separately. Such a separate structural design reduces maintenance costs.
[0042] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
