Description

Technical Field

[0001] This utility model relates to the field of electronic densitometer technology, and in particular to a portable direct-reading electronic densitometer. Background Technology

[0002] A direct-reading electronic densitometer is an instrument for measuring the density of a substance. It provides density results by directly reading the displayed value. This type of densitometer typically uses electronic sensors and digital processing technology to quickly and accurately measure the density of various substances, including solids and liquids.

[0003] Chinese Patent No. CN222224800U discloses a portable direct-reading electronic densitometer, including an assembly box. The densitometer body is disposed on the inner bottom wall of the assembly box, and a first sliding groove is formed in the middle of the inner bottom wall of the assembly box. A clamping component is disposed inside the first sliding groove. By setting the clamping component, the operator rotates the operating handle to rotate the positive and negative threaded rods along the inner wall of the first sliding groove. Since the threads on both sides of the positive and negative threaded rods are opposite, when the positive and negative threaded rods rotate, they drive the positioning clamps on both sides to move relative to each other, clamping the densitometer body. This prevents the densitometer body from shaking or shifting due to external forces during transportation inside the assembly box, improving the stability when the operator is transporting and carrying it. Furthermore, fixing the densitometer body can reduce unnecessary movement or vibration during transportation, thus keeping the position of the measuring probe unchanged and improving the accuracy of the measurement.

[0004] Existing portable direct-reading electronic densitometers adjust the applicable position of the positioning clamp plate by adjusting the positive and negative threaded rods. However, the operating end of the positive and negative threaded rods is located outside the assembly box. In case of accidental contact during use, the threads of the positive and negative threaded rods will deviate, which will affect the positioning and clamping of the densitometer body. This will cause the electronic densitometer to collide with the clamping components inside the assembly box, resulting in damage to the electronic densitometer, affecting the measurement accuracy, and reducing the practicality of the clamping components.

[0031] Example 1

[0032] like Figure 1 - Figure 4 As shown, this utility model proposes a portable direct-reading electronic densitometer, comprising: a base plate 1, an assembly assembly, a locking assembly 4, a fixing component b, and a densitometer body 7; the assembly assembly is connected to the base plate 1; the assembly assembly includes an assembly box 2 and an assembly cover 3; the assembly cover 3 is connected to one side of the assembly box 2, and the densitometer body 7 is connected inside the assembly box 2; the locking assembly 4 is connected to one side of the outer wall of the assembly box 2; the locking assembly 4 includes a protective cover 401, a protective cover 402, a limiting plate 403, a fixing component a 404, a support component a, a support component b, a locking sleeve a 408, a locking block 409, a locking sleeve b 410, and a locking groove 411; the protective cover 401 is connected to the assembly box 1. On one side of the outer wall of box 2, the protective cover 401 has an opening, which is slidably connected to the protective cover 402. The upper part of the protective cover 402 is connected to the limiting plate 403, which is connected to the upper part of the protective cover 401. The fixing part a 404 is connected to the upper side of the protective cover 401. The support part a and the support part b are respectively connected to the two sides of the inner wall of the protective cover 401. The support part a is connected to the locking sleeve a 408, which is connected to the locking block 409. The support part b is connected to the locking sleeve b 410, which is connected to the locking groove 411. The locking block 409 is connected to the inner wall of the locking groove 411. The fixing part b is connected to the outer wall of the assembly box 2 and is connected to the assembly cover 3. The protective cover 402 has an inverted U-shaped structure, which does not affect the adjustment and use of the components of the assembly. When the protective cover 402 is in use, it slides on the protective cover 401 through the opening and inserts into the slot at the lower end. The slot is set on the base plate 1. The fixing part a404 is rotated in cooperation with the rotating support 5 and the limiting baffle 6, so that the limiting baffle 6 is connected to the limiting plate 403, thereby achieving the connection and fixing of the protective cover 402. The connection between the protective cover 402 and the protective cover 401 achieves the protection of the locking component 4, such as the support part a and the support part b, thereby improving the practicality of the locking component 4.

[0033] To further explain, support component a and support component b have the same structure; support component a includes a bracket 405, a screw 406, and an adjusting plate 407; the bracket 405 is connected to the inside of the protective cover 401, and one end of the bracket 405 is threaded to the screw 406, which is threaded into the adjusting plate 407. A locking sleeve a408 is connected above the adjusting plate 407. By operating the screw 406, the adjusting plate 407 is rotated, causing the locking sleeve to rotate and connect to the periphery of the positive and negative threaded rods 203, facilitating the locking of the positive and negative threaded rods 203 and improving the stability of the positioning clamp 207 in holding the density meter body 7.

[0034] Further explanation: Fixing component b includes a rotating support 5 and a limiting baffle 6; the rotating support 5 is connected to the outside of the assembly box 2, and the limiting baffle 6 is connected to one side of the assembly cover 3; fixing component b and fixing component a404 have the same structure. When the assembly cover 3 and the assembly box 2 are connected and in use, fixing component a404 is used to fix the assembly cover 3, which facilitates the connection between the assembly cover 3 and the assembly box 2, and provides convenient protection for the internal density meter body 7. The internal positioning clamp 207 is used in conjunction to reduce unnecessary movement or vibration during transportation, maintain the position of the measuring probe, and improve the accuracy of the density meter in subsequent use.

[0035] Example 2

[0036] like Figure 1 - Figure 3 As shown, this utility model proposes a portable direct-reading electronic density meter. Based on the above embodiments, this embodiment also details the specific components of the assembly assembly and the way they are fitted together.

[0037] Further explanation: A sliding groove a201 is provided on the connecting surface between the assembly box 2 and the assembly cover 3; a sliding groove b is provided at the bottom of the interior of the assembly box 2, and connecting grooves 202 extend from both sides of the sliding groove b. The sliding groove b connects to a positive and negative threaded rod 203, which is threadedly engaged with a slider a204. Connecting blocks 205 are connected to both sides of the slider a204, and the connecting blocks 205 are slidably connected to guide rods 206. The guide rods 206 are connected in the connecting grooves 202. A positioning clamping plate 207 is connected above the slider a204; the operating end of the positive and negative threaded rod 203 is threaded through a reserved threaded hole and connected to the outside of the assembly box 2. The operating end of the positive and negative threaded rod 203 is connected to the locking component 4. The reserved threaded hole is set on the assembly box 2 and is opposite to the sliding groove b; the positioning clamping plate 207 is connected to the outer wall of the densitometer body 7. The densitometer body 7 is placed inside the assembly box 2. By rotating the positive and negative threaded rod 203 on the outside of the assembly box 2, the positive and negative threaded rod 203 engages with the slider a204, causing the connecting blocks 205 on both sides to slide and connect with the guide rod 206. This achieves the cooperation between the positive and negative threaded rod 203 and the slider a204, allowing the slider a204 to move linearly to the outside of the densitometer body 7, thus positioning and clamping the densitometer body 7. There are two sliders a204, two connecting blocks 205, and two positioning clamps 207, which are used to position the densitometer body 7 on both sides, avoiding collision damage to the direct-reading electronic densitometer in the assembly box 2 during transportation, and facilitating the transportation and use of the direct-reading electronic densitometer.

[0038] To further explain, the assembly cover 3 is provided with a viewing window 301 and a slider b302 is provided on the surface connecting it to the assembly box 2. The slider b302 is slidably connected within the slide groove a201. The viewing window 301 facilitates observation of the internal direct-reading electronic densitometer. The slider b302 slides from one end of the slide groove a201, connecting the assembly cover 3 and the assembly box 2. After connection, it is fixed in place using the fastener a404, the rotating support 5, and the limiting baffle 6, facilitating the connection and use of the assembly components.

[0039] The working principle of this utility model is as follows: After the direct-reading electronic density meter is placed in the assembly assembly and positioned and clamped by the positioning clamp 207, during the operation of the positive and negative threaded rod 203, the protective cover 401 and the protective cap 402 are separated, allowing the protective cover 401 to open and facilitating the operation of the positive and negative threaded rod 203. After the positive and negative threaded rod 203 is in the correct position with the positioning clamp 207, the operator first operates the support member b, causing the screw 406 connected to the support member b to rotate. The rotation of the screw 406 drives the adjusting plate 407, which in turn drives the locking sleeve b410. The locking sleeve b410 is rotatably connected to the external operating end of the positive and negative threaded rod 203 and drives the engagement groove 411. A fixing locking screw is provided on one side of the bracket 405. The cap thread is used in conjunction with the screw 406, and then the screw 406 connected to the support member b is operated to make the locking sleeve a408 rotate and drive the locking block 409, so that the locking block 409 is engaged with the locking groove 411. Then the locking sleeve a408 and the locking sleeve b410 are connected to the outer periphery of the positive and negative threaded rod 203 on the outer part of the assembly box 2, so as to lock the positive and negative threaded rod 203. After locking, the lower part of the protective cover 402 passes through the opening and connects to the slot. The limiting plate 403 on the protective cover 402 is connected to the protective cover 401. The fixing member a404 is used to firmly connect the protective cover 402 and the protective cover 401, which facilitates the transportation of the assembly components and protects the structure of the direct-reading electronic densitometer, and facilitates the improvement of the accuracy of subsequent direct-reading electronic densitometer measurements.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
