Description

Technical Field

[0001] The utility model relates to the technical field of electronic density meters, in particular to a portable direct-reading electronic density meter. Background Art

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

[0003] When an electronic density meter is currently transported, it is often installed inside a box to facilitate carrying and transportation. However, if there is no device to fix the electronic density meter inside the box, when encountering external force, it is easy for the electronic density meter to collide with the inner wall of the box, which may not only cause damage to the outer surface of the electronic density meter, but also affect the position of the measuring probe, resulting in inaccurate subsequent measurement data. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a portable direct-reading electronic density meter.

[0005] The utility model is implemented by the following technical scheme: a portable direct-reading electronic density meter, comprising an assembly box, the inner bottom wall of the assembly box is provided with a density meter body, a first slide groove is opened in the middle of the inner bottom wall of the assembly box, and a clamping assembly is arranged inside the first slide groove;

[0006] The clamping assembly includes a first slider, there are two first sliders, which are slidably connected to both sides of the first slide groove, respectively, a positioning clamp is fixedly connected to the surface of the first slider, and a positive and negative threaded rod is provided at the bottom of the first slider, and one end of the positive and negative threaded rod is rotatably connected to the inner wall of the first slide groove.

[0007] Through the above technical solution, personnel rotate the operating handle to make the positive and negative threaded rods rotate along the inner wall of the first slide groove. Since the threads engraved on both sides of the positive and negative threaded rods are opposite, when the positive and negative threaded rods rotate, the positioning clamps on both sides are driven to move relative to each other, thereby clamping the density meter body. When the density meter body is transported inside the assembly box, it will not shake or shift due to external forces, thereby improving the stability of personnel during transportation and carrying, reducing the collision between the density meter body and the outside world, and increasing the service life of the density meter body. In addition, fixing the density meter body can reduce unnecessary movement or vibration during transportation, thereby keeping the position of the measuring probe unchanged and improving the measurement accuracy.

[0008] As a further improvement of the above solution, the positioning clamp is slidably connected to the inner bottom wall of the assembly box through a first slider, and the other end of the forward and reverse threaded rod is fixedly connected to an operating handle.

[0009] Through the above technical solution, personnel rotate the operating handle to rotate the positive and negative threaded rods. Since the threads engraved on both sides of the positive and negative threaded rods are opposite, when the positive and negative threaded rods rotate, the positioning clamps on both sides are driven to move relative to each other to clamp the density meter body.

[0010] As a further improvement of the above solution, both sides of the upper surface of the assembly box are fixedly connected with anti-slip handles, and the surface material of the anti-slip handles is rubber.

[0011] Through the above technical solution, the natural rubber or synthetic rubber has excellent anti-slip performance and flexibility, which can increase the friction when the person holds the assembly box, and prevent the person from slipping out of the hand, resulting in the assembly box falling and being damaged.

[0012] As a further improvement of the above solution, a second slide groove is provided at the top and the bottom of the front end of the assembly box, and a second sliding block is slidably connected inside the second slide groove.

[0013] Through the above technical solution, the second slider slides inside the second slide groove to limit the protective cover and prevent the protective cover from deviating from the motion track when moving.

[0014] As a further improvement of the above solution, a protection cover is fixedly connected to one side of the second sliding block, and the protection cover is slidably connected to the front end of the assembly box through the second sliding block.

[0015] Through the above technical solution, the protective cover slides through the second slider, which is not only simple and convenient to move, but also convenient for personnel to disassemble the protective cover and maintain the density meter body.

[0016] As a further improvement of the above solution, a transparent observation window is provided in the middle of the front end of the protective cover, and a handle is fixedly connected to one side of the front end of the protective cover.

[0017] Through the above technical solution, a person can move the protective cover left and right through the handle, so that the protective cover can be removed along the second sliding groove.

[0018] As a further improvement of the above solution, a rotating support is fixedly connected to one side of the outer surface of the assembly box, and a limit stopper is fixedly connected to the surface of the rotating support.

[0019] Through the above technical solution, after the personnel install the protective cover, they rotate the limit block on the surface of the rotating support to change the angle of the limit block so that the limit block can resist and fix the protective cover to prevent the protective cover from being affected by external forces and sliding off.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a clamping assembly, and a person turns the operating handle to make the positive and negative threaded rods rotate along the inner wall of the first sliding groove. Since the threads engraved on both sides of the positive and negative threaded rods are opposite, when the positive and negative threaded rods rotate, the positioning clamps on both sides are driven to move relatively, and the density meter body is clamped, so that when the density meter body is transported inside the assembly box, it will not shake or shift due to external forces, thereby improving the stability of the person when transporting and carrying it, and fixing the density meter body can reduce unnecessary movement or vibration during transportation, so that the position of the measuring probe can be kept unchanged, thereby improving the measurement accuracy.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Example:

[0031] Please combine Figure 1-5A portable direct-reading electronic density meter of this embodiment includes an assembly box 1, a density meter body 2 is provided on the inner bottom wall of the assembly box 1, a first slide groove 3 is provided in the middle of the inner bottom wall of the assembly box 1, and a clamping assembly 4 is provided inside the first slide groove 3;

[0032] The clamping assembly 4 includes a first slider 401. There are two first sliders 401, which are slidably connected to the two sides of the first slide groove 3 respectively. A positioning clamp 402 is fixedly connected to the surface of the first slider 401. A positive and negative threaded rod 403 is arranged at the bottom of the first slider 401. One end of the positive and negative threaded rod 403 is rotatably connected to the inner wall of the first slide groove 3. A person rotates the operating handle 5 to make the positive and negative threaded rod 403 rotate along the inner wall of the first slide groove 3. Since the threads engraved on both sides of the positive and negative threaded rod 403 are opposite, when the positive and negative threaded rod 403 rotates, the positioning clamps 402 on both sides are driven to move relatively, and the density meter body 2 is clamped, so that the density meter body 2 will not shake or shift due to external forces when being transported inside the assembly box 1, thereby improving the stability of the person when transporting and carrying, reducing the collision between the density meter body 2 and the outside world, and improving the service life of the density meter body 2. In addition, fixing the density meter body 2 can reduce unnecessary movement or vibration during transportation, so that the position of the measuring probe can be kept unchanged, and the measurement accuracy can be improved.

[0033] The positioning clamp 402 is slidably connected to the inner bottom wall of the assembly box 1 through the first slider 401, and the other end of the forward and reverse threaded rod 403 is fixedly connected to the operating handle 5. The operator rotates the operating handle 5 to rotate the forward and reverse threaded rod 403. Since the threads engraved on both sides of the forward and reverse threaded rod 403 are opposite, when the forward and reverse threaded rod 403 rotates, the positioning clamps 402 on both sides are driven to move relative to each other to clamp the density meter body 2.

[0034] Anti-slip handles 6 are fixedly connected to both sides of the upper surface of the assembly box 1. The surface material of the anti-slip handles 6 is rubber. Natural rubber or synthetic rubber has excellent anti-slip performance and flexibility, which can increase the friction when a person holds the assembly box 1, avoiding the problem that the person slips out of the hand and causes the assembly box 1 to fall and be damaged.

[0035] A second slide groove 7 is provided at the top and bottom of the front end of the assembly box 1. A second slider 8 is slidably connected inside the second slide groove 7. The second slider 8 slides inside the second slide groove 7 to limit the protective cover 9 to prevent the protective cover 9 from deviating from the motion trajectory when moving.

[0036] A protective cover 9 is fixedly connected to one side of the second slider 8, and the protective cover 9 is slidably connected to the front end of the assembly box 1 through the second slider 8. The protective cover 9 slides through the second slider 8, which is not only simple and convenient to move, but also convenient for personnel to disassemble the protective cover 9 and maintain the density meter body 2.

[0037] A transparent observation window 10 is provided in the middle of the front end of the protective cover 9 , and a handle 11 is fixedly connected to one side of the front end of the protective cover 9 . A person can move the protective cover 9 left and right through the handle 11 to disassemble the protective cover 9 along the second slide groove 7 .

[0038] A rotating support 12 is fixedly connected to one side of the outer surface of the assembly box 1, and a limit stop 13 is fixedly connected to the surface of the rotating support 12. After the personnel have installed the protective cover 9, the limit stop 13 on the surface of the rotating support 12 is rotated to change the angle of the limit stop 13 so that the limit stop 13 can resist and fix the protective cover 9 to prevent the protective cover 9 from being affected by external forces and sliding off.

[0039] The implementation principle of a portable direct-reading electronic density meter in the embodiment of the present application is as follows: a person first places the density meter body 2 into the assembly box 1, and then rotates the operating handle 5 on the outer surface of the assembly box 1 to make the positive and negative threaded rod 403 rotate along the inner wall of the first slide groove 3. Since the threads engraved on both sides of the positive and negative threaded rod 403 are opposite, when the positive and negative threaded rod 403 rotates, the positioning clamps 402 on both sides are driven to move relative to each other to clamp the density meter body 2, so that the density meter body 2 will not shake or shift due to external forces when being transported inside the assembly box 1, thereby improving the stability of the person in transportation and carrying, and reducing the occurrence of the density meter body 2 with the outside world. The anti-skid handle 6 is made of rubber, which can increase the friction when the person holds the assembly box 1, and prevent the person from slipping out of the handle, causing the assembly box 1 to fall and be damaged.

[0040] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
