Description

Technical Field

[0001] This utility model relates to the field of detection and sampling technology, and more specifically, to a powder sampling spoon. Background Technology

[0002] In chemical experiments and testing, it is often necessary to take samples of reagents and samples. Currently, solid powder samples are usually taken using small plastic or stainless steel spoons.

[0003] However, when using a traditional sampling spoon, if the bottle opening is small, the spoon may easily touch the bottle opening when it is taken out, which may cause the powder sample to spill. Even if the sample is safely removed from the bottle, there is still a risk of spillage during sample transfer. Therefore, this utility model provides a powder sampling spoon. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a powder sampling spoon, which solves the problem that in the prior art, when the sampling spoon is inserted into a bottle containing chemical powder for sampling, if the bottle opening is small, the sampling spoon can easily hit the bottle opening when it is taken out, which may cause the chemical powder to spill. Even if the personnel safely remove the sample from the bottle, there is still a risk of spillage during the sample transfer process.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A powder sampling spoon includes a handle, one end of which is fixedly connected to a spoon body. A groove is formed on the outer circumferential surface of the handle. A metal spring is fixedly connected to the inner wall of the groove. A linkage rod is rotatably connected to one end of the metal spring. A connecting rod is rotatably connected to the end of the linkage rod away from the metal spring. A connecting block is fixedly connected to one end of the connecting rod. A spoon cover is fixedly connected to one side of the connecting block.

[0009] A connecting block is also fixedly connected to the slot, and a limiting sleeve is fixedly connected to the upper end of the connecting block. The limiting sleeve is sleeved on the outer circumference of the connecting rod.

[0010] Furthermore, a reinforcing block is fixedly connected to the inner wall of the slot, and the metal spring is specifically fixedly connected to one side of the reinforcing block.

[0011] Furthermore, the end of the metal spring near the linkage rod is a thickened area, and the end of the metal spring near the inner wall of the slot is a thinned area.

[0012] Furthermore, the surface of the metal spring is provided with a widened area, and a rubber layer is fixedly connected to the surface of the widened area.

[0013] Furthermore, a limiting post is fixedly connected to the surface of the slot, and the limiting post is located below the metal spring sheet.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) Personnel holding the spoon handle in this plan insert the spoon body into the bottle containing chemical powder to take a sample. After the sample is taken, press the metal spring. One end of the metal spring will move downward. As one end of the metal spring moves downward, in conjunction with the transmission of the linkage rod and the limiting sleeve, the connecting rod will eventually drive the spoon cover to seal on the spoon body, thereby sealing the powder sample inside the spoon body, which can effectively reduce the possibility of powder sample spillage.

[0017] (2) In this plan, the personnel hold the spoon handle in the posture of holding a pen, place the spoon handle on the tiger's mouth, and press the metal spring with their thumb. The specific operation method is in line with the normal behavior habits of personnel and is convenient for personnel to operate and use. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example

[0026] like Figure 1-4 As shown, a powder sampling spoon includes a spoon handle 1, a spoon body 2 is fixedly connected to one end of the spoon handle 1, a groove 101 is opened on the outer circumferential surface of the spoon handle 1, a metal spring 3 is fixedly connected to the inner wall of the groove 101, a linkage rod 4 is rotatably connected to one end of the metal spring 3, a connecting rod 5 is rotatably connected to the end of the linkage rod 4 away from the metal spring 3, a connecting block 6 is fixedly connected to one end of the connecting rod 5, and a spoon cover 7 is fixedly connected to one side of the connecting block 6.

[0027] A connecting block 8 is also fixedly connected to the slot 101. A limiting sleeve 9 is fixedly connected to the upper end of the connecting block 8. The limiting sleeve 9 is sleeved on the outer circumference of the connecting rod 5.

[0028] When using the spoon, the operator holds the handle 1 like a pen, placing the handle 1 on the web of their hand and pressing the metal spring 3 with their thumb. Then, the spoon body 2 is inserted into the bottle containing the chemical powder to take a sample. After taking the sample, the operator presses the metal spring 3, and one end of the metal spring 3 will move downwards. As one end of the metal spring 3 moves downwards, in conjunction with the transmission of the linkage rod 4 and the limiting sleeve 9, the connecting rod 5 will eventually drive the spoon cover 7 to seal onto the spoon body 2, thereby sealing the powder sample inside the spoon body 2. This effectively reduces the possibility of powder sample spillage, and its specific operation method conforms to normal human behavior habits, making it convenient for personnel to operate and use.

[0029] like Figure 1-2 As shown, a reinforcing block 1011 is fixedly connected to the inner wall of the slot 101, and the metal spring 3 is specifically fixedly connected to one side of the reinforcing block 1011.

[0030] When in use, the spoon handle 1 is cylindrical, and the arc-shaped surface contacts the user's thumb and forefinger, making it more comfortable for the user. However, after the groove 101 is opened on the cylindrical surface, its semi-circular cross-section has less contact surface with the thin metal spring 3, which can easily lead to unstable connection. However, by connecting with the reinforcing block 1011, the stability of the installation of the metal spring 3 can be effectively improved.

[0031] like Figure 2 and Figure 4 As shown, the end of the metal spring 3 near the linkage rod 4 is the thickened area 302, and the end of the metal spring 3 near the inner wall of the slot 101 is the thinned area 301.

[0032] In use, the thickened area 302 makes the connection between the metal spring 3 and the linkage rod 4 less prone to deformation, ensuring the stability of the connection. The thinned area 301 can improve the elasticity of the connection between the metal spring 3 and the slot 101, making the metal spring 3 more prone to elastic deformation.

[0033] like Figure 4 As shown, the surface of the metal spring 3 is provided with a widened area 303, and a rubber layer 304 is fixedly connected to the surface of the widened area 303.

[0034] When in use, the widened area 303, combined with the rubber layer 304, makes it more comfortable for people to press.

[0035] like Figure 3-4 As shown, a limiting post 1012 is fixedly connected to the surface of the slot 101, and the limiting post 1012 is located below the metal spring 3.

[0036] When in use, when the spoon lid 7 and the spoon body 2 overlap, the metal spring 3 just comes into contact with the limiting post 1012. The limiting post 1012 limits the metal spring 3 to prevent the metal spring 3 from being pressed too much, causing the spoon lid 7 and the spoon body 2 to be misaligned, thus affecting the seal.

[0037] In summary, the specific working process of this solution is as follows: The operator holds the spoon handle 1 in a pen-holding posture, placing the handle 1 on the web of their hand. Then, the spoon body 2 is inserted into the bottle containing the chemical powder for sampling. After sampling, the metal spring 3 is pressed, causing one end of the spring 3 to move downwards. As the spring 3 continues to move downwards, in conjunction with the transmission of the linkage rod 4 and the limiting sleeve 9, the connecting rod 5 will eventually cause the spoon cover 7 to seal onto the spoon body 2, thus sealing the powder sample inside the spoon body 2 and effectively reducing the possibility of leakage. When it is necessary to remove the sample, the metal spring 3 can be released, causing it to move upwards and return to its original position. This releases the spoon cover 7 from the spoon body 2, allowing the operator to pour out the chemical powder. This utility model's operating method conforms to normal human behavior and is convenient for operation.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
