Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a calcium powder sampling device. Background Art

[0002] Calcium powder, commonly known as limestone or stone powder, is a compound with the chemical formula of CaCO3, which is alkaline, basically insoluble in water, but soluble in acid.

[0003] In the production process of calcium powder, whether it is sampling and testing semi-finished products or inspecting finished products before they are sold, a sampling device is required. Traditional single-point sampling devices require multiple samplings at different positions to ensure the accuracy and credibility of the test data, and the sampling efficiency is relatively low. In the prior art, a multi-point sampling device has been studied, which can perform multi-point sampling at one time and improve the sampling efficiency.

[0004] The existing multi-point sampling device generally adopts the method of relative rotation of the inner cylinder and the outer cylinder for sampling, so that the outer cylinder and the opening on the inner cylinder move relative to each other to open and close the sampling port. However, in the actual sampling operation, the operator needs to operate with both hands, one hand holding the outer cylinder and the other hand rotating the inner cylinder, and it needs to be rotated in place. At the same time, in order to prevent the calcium powder material from entering during the insertion and removal of the sampling device, the operator needs to hold the inner cylinder and the outer cylinder with both hands during this process to ensure that there is no relative rotation and avoid the sampling port from opening. In summary, the existing multi-point sampling device has many precautions in use, and has certain requirements for operators, which brings some inconvenience to the personnel. Therefore, an easy-to-operate sampling device needs to be developed. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a calcium powder sampling device. During the insertion and extraction process, the inner port and the outer port are misaligned by the force of the stretching spring to prevent the calcium powder material from entering. When sampling, the inner tube is pulled by the fingers of the person to make the inner port and the outer port correspond to each other and sample is taken. In this process, the operation can be completed with one hand, and no other operation requirements are required. The operation is simple for the person to operate and sampling is convenient.

[0017] like Figure 1-2As shown, a calcium powder sampling device comprises an inner tube 2, an outer tube 1, a handle 4 and a pull handle 5. One end of the outer tube 1 is open and the outer wall is fixedly connected to the handle 4. The inner tube 2 is movable and penetrates the outer tube 1. The outer wall diameter of the inner tube 2 is equal to the inner wall diameter of the outer tube 1. The inner tube 2 is provided with a pull handle 5 at one end corresponding to the handle 4, and a plurality of tension springs 3 are provided between the other end and the outer tube 1. A plurality of inner openings 8 are evenly provided on the side wall of the inner tube 2. The inner tube 2 is provided with partitions 6 on both sides corresponding to the inner openings 8. The position of the outer tube 1 corresponding to each inner opening 8 is arranged on the side wall of the outer tube 1. An outer opening 7 is provided, and the tension spring 3 can axially pull the inner tube 2 so that the inner opening 8 and the outer opening 7 do not overlap. A sliding member for axial direction limiting is provided between the inner tube 2 and the outer tube 1; the sliding member includes a slide groove 10 and a slide bar 11, and the slide bar 11 is provided on the inner side wall of the outer tube 1 corresponding to the end of the handle 4 along the axial direction, and the slide groove 10 is opened on the outer side wall of the inner tube 2 along the axial direction, and the slide bar 11 is slidably connected with the slide groove 10; a pointed head 9 is provided at the end of the outer tube 1 corresponding to the handle 4; and contour grooves are provided on the handle 4 and the handle 5, respectively.

[0018] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] According to the instruction manual Figure 1-2 It can be known that when the utility model is working, the personnel grasps the handle 4 with one hand and inserts the outer cylinder 1 into the calcium powder material. In this process, the personnel can complete the operation with one hand. Since the outer cylinder 1 and the inner cylinder 2 are sleeved and can slide axially, under the action of the tension spring 3, the inner cylinder 2 is subjected to a force to the left. In the absence of other external forces, the outer opening 7 on the outer cylinder 1 and the inner opening 8 on the inner cylinder 2 are completely staggered, that is, they do not overlap. Therefore, when inserting, no other operation is required, and the material will not be in the space formed by the partition 6, which can be called a sample box here. After insertion, the personnel hook the handle 5 with the finger of one hand to move the inner cylinder 2 to the left, the tension spring 3 is stretched, and the inner opening 8 and the outer opening 7 can overlap. At this time, the personnel simply shake or turn the handle 4 and the outer cylinder 1 to allow the material to enter the sample box, and then the personnel release their fingers, and the reaction force of the tension spring 3 again moves the inner cylinder 2 to the left, and the inner opening 8 and the outer opening 7 are completely staggered again, and the material cannot enter the sample box. The work during the extraction is roughly the same as that during the insertion. The personnel do not have to do other operations. Just pull the handle 4 with one hand to pull out the device. The function of the sliding part ensures that the axial sliding of the inner cylinder 2 is stable while preventing it from rotating. When unloading the sample, the finger hooks the handle 5 to pour out the material. During the insertion and extraction process, the inner opening 8 and the outer opening 7 are dislocated by the force of the tension spring 3 to prevent the calcium powder material from entering. When sampling, the inner cylinder 2 is pulled by the personnel's fingers to make the inner opening 8 correspond to the outer opening 7 and sample. In this process, the operation can be completed with one hand, and there are no other operation requirements. The personnel are simple to operate and convenient for sampling.

[0020] Among them, the sliding part includes a slide groove 10 and a slide bar 11. The slide bar 11 is arranged on the inner wall of the outer tube 1 corresponding to the handle 4 along the axial direction. The slide groove 10 is opened on the outer wall of the inner tube 2 along the axial direction. The slide bar 11 is slidably connected with the slide groove 10 to ensure the axial sliding stability of the inner tube 2 while preventing it from rotating.

[0021] The end of the outer tube 1 corresponding to the end away from the handle 4 is provided with a pointed tip 9 to facilitate the insertion of the sampling device into the calcium powder material.

[0022] In addition, the handle 4 and the pull handle 5 are respectively provided with contoured grooves, which are designed according to the shape of human hands, so that people can feel more comfortable and easy to operate when using them.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
