Description

Technical Field

[0001] This utility model relates to the field of densitometer technology, specifically to a temperature-resistant drift component for a densitometer. Background Technology

[0002] As the name suggests, a hydrometer is an instrument used to measure the density of fluids. Hydrometers are commonly used in industrial production. When a hydrometer is in use, according to Archimedes' principle, when an object is immersed in a liquid, it will experience an upward buoyant force, which is equal to the weight of the liquid displaced by the object.

[0003] For example, Chinese Patent Publication No. CN202021659749.4 provides a liquid density meter, including a base with a mounting groove in the middle of the base's bottom surface. A central processing unit is disposed inside the mounting groove, and a touch display screen is disposed at the front end of the base's outer surface. The advantage of this invention is that by arranging the central processing unit inside the base and a pressure sensor component on the top surface of the base, a tray on the top surface of the pressure sensor component, and a glass beaker on the top surface of the tray, a temperature sensor component and a standard glass weight ball are placed inside the glass beaker during use. Both the temperature sensor component and the pressure sensor component are electrically connected to the central processing unit, thereby enabling temperature measurement and liquid density measurement based on changes in the pressure sensor component. The measurement results are then displayed on the touch display screen, thus solving the problem that temperature affects liquid density.

[0004] When the above-mentioned density meter is in use, its up-and-down drifting component has the following problems when moving the standard weight ball: the above device requires twisting the locking bolt and then continuously moving the crossbar when moving the standard weight ball, which makes the overall operation process more cumbersome and makes it difficult to guarantee the stability of the up-and-down movement of the crossbar. Utility Model Content

[0005] To address this issue, the present invention provides a temperature-resistant drift component for a densitometer, thereby solving the problem in the prior art where the operation process is cumbersome and the stability of the horizontal bar's up-and-down movement is difficult to guarantee because the device requires twisting and tightening the locking bolts and continuously moving the crossbar when moving the standard weight ball.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A temperature-resistant drift component for a densitometer includes a measuring base, a measuring platform mounted on top of the measuring base, and a sample beaker placed on the measuring platform. The sample beaker contains a sample liquid. A fixed upright is fixedly connected to one side of the measuring base, and a threaded rod is fixedly installed on the other side of the measuring base. A movable threaded sleeve is threaded onto the outer ring of the threaded rod. A movable crossbar is rotatably connected to the movable threaded sleeve and the fixed upright through a rotational displacement component. A glass weight ball is hung on the movable crossbar. The movable threaded sleeve and the threaded rod are limited in movement by a movement restriction component.

[0008] Furthermore, the fixed pole and the threaded rod are of the same height and are symmetrically arranged with reference to the central axis of the measuring base. The outer diameters of the fixed pole and the threaded rod are also equal.

[0009] Furthermore, the inner ring of the movable threaded sleeve is provided with a threaded groove, and the threaded groove of the inner ring of the movable threaded sleeve is threadedly connected to the thread of the outer ring of the threaded rod. The movable threaded sleeve and the threaded rod are connected vertically, and when the movable threaded sleeve is rotated, the height position is moved at the same time as the movable threaded sleeve rotates.

[0010] Furthermore, the left and right ends of the movable crossbar are movably connected to the fixed upright and the movable threaded sleeve respectively through a rotational displacement assembly, and a vertically arranged short rod is fixedly connected to the right end of the movable crossbar, so that the movement of the height position of the movable threaded sleeve can drive the synchronous movement of the height position of the movable crossbar.

[0011] Furthermore, the rotary displacement assembly includes a vertical limiting groove 1 pre-set inside the fixed upright, and the inner wall of the vertical limiting groove 1 is attached to the outer wall of the columnar rod of the movable crossbar to achieve a sliding connection between the upper and lower parts. The rotary displacement assembly also includes an annular groove 1 pre-set inside the movable threaded sleeve, and the inner wall of the annular groove 1 is attached to the outer wall of the right end of the movable crossbar to achieve a sliding connection. Moreover, the annular groove 1 is not connected to the threaded groove. In this way, when the movable threaded sleeve rotates, it will only drive the movable crossbar to move in height, and the movable crossbar will not hinder the rotation of the movable threaded sleeve.

[0012] Furthermore, the movement restriction component includes a limiting plate reserved inside the movable threaded sleeve, and a connecting rod is fixedly inserted at the middle position of the limiting plate. The two ends of the connecting rod are rotatably connected to the annular groove reserved inside the movable threaded sleeve, so that the movement restriction component does not affect the rotation of the movable threaded sleeve.

[0013] Furthermore, the limiting plate is square, and both its upper and lower ends are flush with the upper and lower ends of the movable threaded sleeve.

[0014] Furthermore, the limiting movement component also includes a second vertical limiting groove preset inside the threaded rod, and the inner wall of the second vertical limiting groove is attached to the outer wall of the limiting plate to achieve a sliding connection between the upper and lower parts. Both the upper and lower ends of the second vertical limiting groove are closed. The movement distance of the movable threaded sleeve is limited by the second vertical limiting groove with a limited height, thus preventing the movable threaded sleeve from separating from the threaded rod.

[0015] This utility model has the following advantages:

[0016] In use, this invention involves rotating the movable threaded sleeve, causing it to move up and down. This movement, in turn, drives the movable crossbar, which is rotatably connected to the annular groove inside the movable threaded sleeve, to move up and down synchronously under the constraint of the vertical limiting groove inside the fixed upright. This movement causes the glass weight ball, which is mounted on the outer ring of the movable crossbar, to descend into the sample beaker to measure the density of the sample solution. This ensures that the adjustment of the movable crossbar is more convenient, faster, and more stable. Simultaneously, the rotational displacement component and the movement limiting component that assist in the up-and-down drift of the glass weight ball are moved away from the sample beaker, ensuring that the liquid temperature in the sample beaker has no effect on the drift component. This allows the drift component to withstand high temperatures and extends its service life. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This utility model provides, for example Figure 1-4 The temperature-resistant drift assembly of a densitometer shown includes a measuring base 1, a measuring platform 2 mounted on the top of the measuring base 1, and a sample beaker 3 placed on the measuring platform 2. The sample beaker 3 contains sample liquid. A fixed upright 4 is fixedly connected to one side of the measuring base 1, and a threaded rod 5 is fixedly installed on the other side of the measuring base 1. A movable threaded sleeve 6 is threaded onto the outer ring of the threaded rod 5. A movable crossbar 7 is rotatably connected to the movable threaded sleeve 6 and the fixed upright 4 through a rotational displacement assembly 8. A glass weight ball 10 is hung on the movable crossbar 7. The movable threaded sleeve 6 and the threaded rod 5 are limited in movement by a movement restriction assembly 9.

[0026] In use, rotating the movable threaded sleeve 6 causes it to move up and down during its rotation, which is threaded to the threaded rod 5. This movement, in turn, causes the movable crossbar 7, which is rotatably connected to the annular groove 802 inside the movable threaded sleeve 6, to move up and down synchronously under the constraint of the vertical limiting groove 801 inside the fixed rod 4. This causes the glass weight ball 10, which is mounted on the outer ring of the movable crossbar 7, to descend into the sample beaker 3 to measure the density of the sample solution. The results are then read from the display screen of the measuring base 1. (The use of the measuring device is a readily available and relatively mature technology, and will not be described in detail here.)

[0027] To facilitate the adjustment of the position and height of the movable crossbar 7, the fixed upright 4 and the threaded rod 5 are set to have the same height and are symmetrically arranged with reference to the central axis of the measuring base 1. The outer diameters of the fixed upright 4 and the threaded rod 5 are equal. The inner ring of the movable threaded sleeve 6 is provided with a threaded groove, and the threaded groove of the inner ring of the movable threaded sleeve 6 is threadedly connected to the pre-set thread on the outer ring of the threaded rod 5. The movable threaded sleeve 6 and the threaded rod 5 are connected to move up and down. When the movable threaded sleeve 6 is rotated, the height position is moved at the same time.

[0028] To facilitate the movement of the movable crossbar 7, the left and right ends of the movable crossbar 7 are movably connected to the fixed upright 4 and the movable threaded sleeve 6 respectively through the rotation displacement assembly 8. Furthermore, a vertically arranged short rod is fixedly connected to the right end of the movable crossbar 7, which facilitates the synchronous movement of the height position of the movable threaded sleeve 6.

[0029] Rotating the movable threaded sleeve 6 causes it to move up and down during the rotation, as it is threaded to the threaded rod 5. The two ends of the movable crossbar 7 are movably connected to the vertical limiting groove 801 inside the fixed upright 4 and the annular groove 802 reserved inside the movable threaded sleeve 6, respectively. Thus, when the movable threaded sleeve 6 moves up and down, it drives the movable crossbar 7 to move synchronously.

[0030] The rotational displacement component 8 includes a vertical limiting groove 801 pre-set inside the fixed upright 4, and the inner wall of the vertical limiting groove 801 is attached to the outer wall of the columnar rod of the movable crossbar 7 to achieve a sliding connection between the upper and lower parts. The rotational displacement component 8 also includes an annular groove 802 pre-set inside the movable threaded sleeve 6, and the inner wall of the annular groove 802 is attached to the outer wall of the right end of the movable crossbar 7 to achieve a sliding connection. The annular groove 802 is not connected to the threaded groove. In this way, when the movable threaded sleeve 6 rotates, it will only drive the movable crossbar 7 to move in height, and the movable crossbar 7 will not hinder the rotation of the movable threaded sleeve 6.

[0031] When the movable threaded sleeve 6 is rotated to move up and down, the movable crossbar 7, which is rotatably connected to the movable threaded sleeve 6, moves up and down simultaneously under the limiting action of the vertical limiting groove 801.

[0032] To ensure that the setting of the limiting movement component 9 does not affect the rotation of the movable threaded sleeve 6, the limiting movement component 9 includes a limiting plate 902 reserved inside the movable threaded sleeve 6, and a plug rod 903 is fixedly inserted in the middle position of the limiting plate 902. The two ends of the plug rod 903 are rotatably connected to the annular groove 904 reserved inside the movable threaded sleeve 6. In this way, the limiting movement component 9 does not affect the rotation of the movable threaded sleeve 6. The limiting plate 902 is a square plate, and the upper and lower ends of the limiting plate 902 are flush with the upper and lower ends of the movable threaded sleeve 6.

[0033] The movement restriction component 9 also includes a vertical limiting groove 901 pre-set inside the threaded rod 5. The inner wall of the vertical limiting groove 901 is attached to the outer wall of the limiting plate 902 to achieve a sliding connection between the upper and lower parts. Both the upper and lower ends of the vertical limiting groove 901 are closed. The movement distance of the movable threaded sleeve 6 is limited by the vertical limiting groove 901 with a limited height, so as to prevent the movable threaded sleeve 6 from separating from the threaded rod 5.

[0034] During the rotation of the movable threaded sleeve 6, the annular groove 904 reserved inside the movable threaded sleeve 6 is rotatably connected to the plug rod 903, so that the non-rotating limiting plate 902 and the plug rod 903 will not affect the rotation of the movable threaded sleeve 6. At the same time, when the movable threaded sleeve 6 moves up and down, it synchronously drives the plug rod 903 and the limiting plate 902 fixedly connected to the outer ring of the plug rod 903 to move up and down synchronously inside the vertical limiting groove 901 reserved inside the threaded rod 5. Since the upper and lower ends of the vertical limiting groove 901 are both closed, the range of vertical movement of the movable threaded sleeve 6 is limited, thus preventing the movable threaded sleeve 6 from separating from the threaded rod 5.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
