Description

Technical Field

[0001] The utility model relates to the technical field of moisture measurement, in particular to a moisture measurement device. Background Art

[0002] Sea bass is a highly nutritious seafood delicacy with high demand both domestically and internationally. However, during the aquaculture process, sea bass are often susceptible to diseases such as Saprolegniasis, enteritis, and black body disease, which can cause death. To ensure a healthy aquaculture environment, farmers are required to regularly test the aquaculture water, typically using a moisture meter to measure the moisture content of water samples.

[0003] Announcement No. CN217820301U discloses a moisture measuring device for sea bass farming, comprising a measuring instrument body and an upper cover mounted on top thereof. By pushing the buckle upward, the rotating sleeve drives the clamp head to rotate outward along the metal rod and disengage from the notch, thereby releasing the clamp head from locking the connecting shaft. The torsion spring pushes the upper cover to reverse and open, effectively avoiding burns caused by contact between the operator and the upper cover when opening the measuring instrument. This greatly improves the safety of the device during use, and only requires a single push to complete the opening, with good operational convenience. The rotating ring can be rotated along the slide to adjust the position of its inner ring block. By adjusting the position of the block, the connecting shaft can be intercepted with the block on its surface when rotating to different angles, so that the connecting shaft cannot continue to rotate. This controls the opening angle of the upper cover, facilitates the operator's use, and makes the device more adaptable when in use. In addition, existing moisture measuring devices also have the following disadvantages during use:

[0004] (1) The control component for controlling the folding angle of the upper cover in the existing moisture measuring device is complex in structure and inconvenient to use. The upper cover closing state limit and angle adjustment limit can only be completed by two components.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figures 1 to 5 As shown, this embodiment proposes a moisture measuring device, including a measuring instrument body 1, a support structure 2, an upper cover 5 and a limiting structure 9. The rear part of the top side of the measuring instrument body 1 is fixedly connected to a hinge seat 3, and the front part of the top side of the measuring instrument body 1 is fixedly connected to a hinge seat 24. The interior of the hinge seat 24 is provided with a cavity. The number of support structures 2 is four groups, and the four groups of support structures 2 are respectively arranged at the four corners of the bottom of the measuring instrument body 1. Each group of support structures 2 includes a fixing rod 201, a sleeve rod 202, a base 203 and a fixing structure 205. One of the fixing rods 201 One end is fixedly connected to the measuring instrument body 1, and the other end is sleeved with a sleeve rod 202. A number of equidistant limit holes 204 are respectively provided on both sides of the outer wall of the sleeve rod 202. The bottom end of the sleeve rod 202 is fixedly connected to the base 203.

The outer walls of both ends of the connecting shaft 6 are respectively sleeved with torsion springs 7, and a limit structure 9 is passed through one side of the inner cavity.

[0030] Example 2:

[0031] The solution in Example 1 is further introduced below in conjunction with the specific working method, as described below for details: Each set of fixed structures 205 includes a telescopic rod 2051, a spring 1 2052 and a protrusion 2053. A telescopic rod 2051 is provided on both sides of the inner cavity.

The outer walls of the two telescopic rods 2051 are respectively sleeved with a spring 1 2052, and the protrusion 2053 is adapted to be connected to the limiting hole 204.

[0032] Four groups of support structures 2 are respectively provided at the four corners of the bottom of the utility model. When the placement surface is uneven, the protrusion 2053 of the sleeve rod 1 202 corresponding to the concave surface is pressed to shrink it and move towards the inner wall of the inner cavity, thereby pulling the sleeve rod 1 202 downward so that the bottom of the base 203 abuts the concave surface, and then the protrusion 2053 is released, and the protrusion 2053 is pushed into the limiting hole 204 through the telescopic rod 2051 and the spring 1 2052 to complete the adjustment of the lifting height, thereby ensuring that the utility model can maintain a relatively horizontal state on an uneven placement surface, thereby increasing the accuracy and applicability of the detection of the utility model.

[0033] Example 3:

[0034] The scheme in Example 2 is further introduced below in combination with the specific working method, and the details are described below: the rear end bearing of the connecting shaft 6 is connected to the articulated seat 1 3, the front end of the connecting shaft 6 passes through the articulated seat 2 4 and extends into the interior of the cavity and is fixedly connected to the thorn gear 8, one end of the two torsion springs 7 is respectively fixedly connected to the upper cover 5, and the other end is respectively fixedly connected to the articulated seat 1 3 and the articulated seat 2 4, the limiting structure 9 includes a fixed rod 2 901, a sleeve rod 2 903, a limiting block 905 and a pulling block 907, one end of the fixed rod 2 901 is fixedly connected to the inner wall of the cavity, and the other end is sleeved with the sleeve rod 2 903, the outer wall of the sleeve rod 2 903 is sleeved with the limiting block 905, and the front end of the sleeve rod 2 903 passes through the articulated seat 2 4 and is inserted with the pulling block 907.

[0035] Example 4:

[0036] The scheme in Example 3 is further introduced below in combination with the specific working method, and the details are described below: the outer wall of the fixed rod 2 901 is provided with an annular movable groove 902, and the front sides of the inner wall of the sleeve rod 2 903 are fixedly connected with movable blocks 904 respectively, and the two movable blocks 904 are respectively adapted to be connected with the movable grooves 902, and the shape of the limit block 905 is thorn tooth-like, and the limit block 905 is bent toward the thorn gear 8, and the limit block 905 is engaged with the thorn gear 8, and the front side of the limit block 905 is fixedly connected with the spring 2 906, and the front end of the spring 2 906 is fixedly connected to the inner wall of the cavity, and the outer wall of the pulling block 907 is sleeved with a heat insulation sleeve.

[0037] Through the cooperation of the limiting structure 9, the thorn gear 8 and the torsion spring 7, the torsion spring 7 normally pushes the upper cover 5 to the open state, and the spring 2 906 of the limiting structure 9 pushes the limiting block 905 to always engage the teeth of the thorn gear 8, so that the thorn gear 8 can be normally folded downward, thereby preventing it from folding upward. When it is necessary to open the upper cover 5, it is only necessary to pull the pulling block 907 in the direction away from the hinge seat 2 4, and the limiting block 905 is driven by the sleeve rod 2 903 to squeeze the spring 2 906, and release the teeth of the thorn gear. The wheel 8 is engaged, and the upper cover 5 is driven to open automatically through the torsion spring 7. When the upper cover 5 is opened to a suitable angle, the pulling block 907 is released, and the limit block 905 is pushed into the tooth gap of the thorn gear 8 through the spring 2 906. The torsion spring 7 gives the upper cover 5 an upward folding force, and the limit block 905 prevents its folding force, thereby ensuring that the angle adjustment of the upper cover 5 is fixed. The structure is simple, and one limit block 905 can simultaneously realize the limit of the closed state of the upper cover 5 and the limit of the angle adjustment, which is easy to use.
