Description

[Technical Field]

[0001] This utility model mainly relates to a tuning fork density meter. [Background Technology]

[0002] Currently, the structure of a tuning fork densitometer generally includes a meter head and a tuning fork assembly. The tuning fork assembly is installed below the meter head and mainly consists of two single tuning fork bodies. When one end of a single tuning fork body is driven by a voltage signal to excite a piezoelectric element to vibrate, the vibration frequency can be transmitted to the other single tuning fork body through the medium. The vibration pickup piezoelectric element located at one end of the other single tuning fork body detects the oscillation frequency and converts the vibration signal into an electrical signal output. This process enables the tuning fork densitometer to measure the density of the liquid being measured.

[0003] Existing tuning fork assemblies are all fixed structures, with a fixed width formed by two single tuning fork bodies. However, tuning fork densitometers generally need to test different sample containers, and the diameter of each container is not necessarily the same, with varying sizes. The applicability of a single-size tuning fork assembly is limited. In view of this, we have improved the tuning fork body structure to be suitable for containers with different diameters. [Utility Model Content]

[0004] To solve at least one of the above problems, this utility model proposes a new structural solution. The tuning fork density meter adopts the following technical solution:

[0005] A tuning fork density meter includes a tuning fork assembly and a meter head assembly. The tuning fork assembly includes two mutually symmetrical main fork bodies, a connecting member, an extension fork body, a fixing insert, and a locking bolt.

[0006] The connector is provided with a first slot, a second slot and a fixing slot. The first slot and the second slot are horizontal, the fixing slot is perpendicular to the first slot, and the first slot, the second slot and the fixing slot are connected.

[0007] Both the main fork and the extension fork are provided with transverse grooves. The main fork is inserted into the first slot, and the extension fork is inserted into the second slot, so that the main fork and the extension fork are connected into a whole by a connector. The fixing plate connects the fixing groove and the transverse groove at the same time. The locking bolt passes through the fixing plate and is connected to the connector to fix the connector, the main fork and the extension fork together.

[0008] Preferably, both the fixing insert and the connector are provided with through holes, and the connector is provided with screw holes, with the through holes and screw holes of the connector located on the same axis.

[0009] Preferably, the main fork, connecting parts, extension fork, fixing insert, and locking bolts are all made of the same material.

[0010] Preferably, the top of the first slot is open and the bottom of the second slot is open.

[0011] Preferably, the locking bolt has threads and hexagonal recesses at both ends.

[0012] The beneficial effects of this utility model compared with the prior art are:

[0013] To adapt the tuning fork structure to containers of different diameters, this invention proposes a tuning fork density meter. It includes two symmetrical main forks, a connector, and an extension fork. The main forks, connector, and extension fork employ a detachable assembly structure. When encountering containers with smaller diameters, the connector is added to the main forks to narrow the gap between them. Simultaneously, the extension fork is used to replace the main forks and extend into the container for measurement. Because the connector is a detachable component, different sizes of connectors can be selected for containers of different diameters, eliminating the need to replace the main tuning fork density meter body, thus broadening its applicability. It boasts advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] The preferred embodiment provided by this utility model is as follows: Figures 1-5 As shown, a tuning fork density meter includes a tuning fork assembly 1 and a meter head assembly 2. The meter head assembly adopts an existing product structure, which will not be described in detail here. The tuning fork assembly 1 includes two symmetrical main fork bodies 2, a connecting piece 3, an extension fork body 4, a fixing insert 5, and a locking bolt 6. The main fork bodies 2, the connecting piece 3, the extension fork body 4, the fixing insert 5, and the locking bolt 6 are all made of the same material to ensure consistent vibration frequencies. The locking bolt 6 has threads and hexagonal recesses at both ends for easy tightening and fixing.

[0023] The connector 3 is provided with a first slot 31, a second slot 32 and a fixing groove 33. The first slot 31 and the second slot 32 do not penetrate the connector 3. The fixing groove 33 penetrates the connector 3 laterally. The length of the fixing insert 5 is the same as the width of the connector 3 to avoid protrusion. The first slot 31 and the second slot 32 are horizontal, and the fixing groove 33 is perpendicular to the first slot 31. The first slot 31, the second slot 32 and the fixing groove 33 are connected. The top of the first slot 31 is open and the bottom of the second slot 32 is open. That is, the open ends of the first slot 31 and the second slot 32 are opposite, which makes it convenient for the main fork body 2 and the extension fork body 4 to be inserted into the connector 3.

[0024] Both the main fork body 2 and the extension fork body 4 are provided with transverse grooves 34. The length of the transverse groove is less than the length of each component. The length of the transverse groove corresponds to the size of the fixing plate. The main fork body 2 is inserted into the first slot 31, and the extension fork body 4 is inserted into the second slot 32, so as to connect the main fork body 2 and the extension fork body 4 into a whole through the connecting member 3. The fixing plate 5 connects the fixing slot 33 and the transverse groove 34 at the same time. The locking bolt 6 passes through the fixing plate 5 and is connected to the connecting member 3 to fix the connecting member 3, the main fork body 2 and the extension fork body 4 together.

[0025] Both the fixing insert 5 and the connecting piece 3 are provided with through holes 35, and the connecting piece 3 is provided with screw holes 36. The through holes 35 and screw holes 36 of the connecting piece 3 are located on the same axis, which facilitates the connection and fixation of the locking bolt 6. The threaded end of the locking bolt is fully screwed into the screw hole.

[0026] Assembly process: When encountering containers with small diameters, install the connecting parts 3 on each of the main fork bodies 2. First, insert the main fork body 2 into the first slot 31, then insert the extension fork body 4 into the second slot 32. Next, insert the fixing plate 5 through the fixing groove 33, the first slot 31, the second slot 32, and the cross groove 34. At this time, the fixing plate 5, the through hole 35, and the screw hole 36 of the connecting part 3 are on the same axis. Finally, insert the locking bolt 6 through the through hole 35 and tighten it on the connecting part 3. The main fork body 2, the connecting part 3, and the extension fork body 4 can be assembled into a whole. The dimensions of each component should be consistent with the dimensions of the corresponding connecting groove so that the components can be tightly connected.

[0027] To adapt the tuning fork structure to containers of different diameters, this invention proposes a tuning fork density meter. It includes two symmetrical main fork bodies 2, a connecting piece 3, and an extension fork body 4. The main fork bodies 2, connecting piece 3, and extension fork body 4 adopt a detachable assembly structure. When encountering containers with smaller diameters, the connecting piece 3 is added to the main fork bodies 2 to narrow the gap between them. Simultaneously, the extension fork body 4 replaces the main fork bodies 2 and extends into the container for measurement. Because the connecting piece 3 is a detachable component, different sizes of connecting pieces 3 can be selected for containers of different diameters, without needing to replace the main body of the tuning fork density meter, thus broadening its applicability.
