Description

Technical Field

[0001] This utility model relates to the field of mortar sampling technology, and in particular to a mortar sampler. Background Technology

[0002] Concrete is used as a wall material in construction. Before concrete is used, it needs to be tested to prevent poor concrete quality from causing building collapse. A concrete mortar sampling device is needed to sample the mortar.

[0003] Chinese utility model patent CN219608515U discloses a mortar sampler. Through the cooperation of a sampling tube, an insertion tube, and a dynamic sealing plate, it facilitates the extraction of mortar from the insertion tube into the sampling tube during mortar sampling. Simultaneously, the sampling port where the mortar enters is sealed during extraction, and the extracted mortar sample can be quickly discharged from the sampling tube, improving the convenience of mortar sampling. However, this mortar sampler still has some drawbacks: during sampling, the sampler is usually inserted into the mortar to a certain depth before sampling. After sampling, to ensure the cleanliness of the sampler's exterior, it is cleaned with water. However, during the cleaning process, water can easily enter the sampler, adversely affecting the mortar sample.

[0004] Therefore, this utility model proposes a mortar sampler to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mortar sampler that does not require cleaning of the surface of the mortar sampler after sampling, thereby ensuring the performance of the mortar sample.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a mortar sampler, the innovation of which lies in: including

[0007] The sampling cylinder has a first external thread section and a second external thread section at the top and bottom of its outer wall, respectively.

[0008] A top end cap covers the top of the sampling cylinder and is connected to the first external thread section in a sealing threaded connection.

[0009] Plastic protective sleeve: The plastic protective sleeve is movably fitted onto the outside of the sampling cylinder, and the bottom of the plastic protective sleeve covers the second external thread section;

[0010] The easy plug is located at the bottom of the sampling cylinder. The top of the easy plug is fitted over the outside of the plastic protective sleeve and is threadedly connected to the second external thread section of the sampling cylinder to fix the bottom of the plastic protective sleeve to the sampling cylinder. The bottom of the easy plug has a tip that is easy to insert into the mortar.

[0011] Furthermore, a sealing ring is provided on the inner side of the top end cap for sealing connection with the first external thread section.

[0012] Furthermore, the mortar sampler also includes a bottom end cap that can be threadedly connected to the second external thread section.

[0013] Furthermore, the sampling tube is a transparent cylindrical structure, and sampling scale lines are provided on the outer wall of the sampling tube. The plastic protective sleeve is a cylindrical transparent plastic film.

[0014] Furthermore, the plastic protective sleeve includes a first transparent plastic film and a second transparent plastic film, and the two sides of the first transparent plastic film and the second transparent plastic film are heat-sealed together to form a cylindrical structure.

[0015] Furthermore, the bottom end face of the easy plug includes two symmetrical inclined surfaces, which slope downwards towards the central axis of the easy plug, and the intersection of the two inclined surfaces at the bottom of the easy plug forms a tip.

[0016] Furthermore, two handles are symmetrically provided on both sides of the top of the sampling cylinder, and the handles are located below the first external thread section.

[0017] Furthermore, both grips are detachably connected to the sampling cylinder. The outer wall of the sampling cylinder has two connecting protrusions that correspond one-to-one with the grips. Each connecting protrusion has an insertion groove on its end face. The top of the plastic protective cover covers the insertion groove. The two grips are respectively inserted into the insertion grooves of the corresponding connecting protrusions, and the plastic protective cover is pressed into the insertion groove for fixation.

[0018] The advantages of this utility model are:

[0019] When sampling, the sampler of this utility model first places a plastic protective sleeve on the outside of the sampling tube, and then installs an easy plug to fix the bottom of the plastic protective sleeve to the sampling tube. At this time, the top of the sampling tube is not installed and is in an open state. The sampling personnel push the lower part of the sampling tube into the mortar, and the mortar in the movement trajectory of the sampling tube enters the tube to become the mortar sample. After the sample volume is sufficient, the top end cap is sealed and installed on the top of the sampling tube. The sampling tube is then pulled out. Whether during or after pulling out, the pressure inside and outside the sampling tube is the same, and the mortar sample can be well retained inside the sampling tube. During the sampling process, the outer wall of the sampling tube is protected by the plastic protective sleeve. After the sampling is completed and the easy plug is removed, the plastic protective sleeve can be removed from the sampling tube. The entire process ensures that the surface of the sampling tube is clean and does not require cleaning, thus effectively protecting the performance of the mortar sample.

[0020] This invention improves the sealing effect between the top end cap and the sampling tube by designing a sealing ring on the top end cap, thus preventing the mortar inside the sampling tube from flowing out from the bottom of the sampling tube due to gravity.

[0021] This invention, by setting a bottom end cap, allows the sampling tube to be pulled out of the mortar, the plug to be removed, and the bottom end cap to be installed at the bottom of the sampling tube. This effectively prevents the mortar near the bottom of the sampling tube from being contaminated or accidentally falling out during transportation.

[0022] The sampling tube of this utility model is a transparent cylindrical structure. The outer wall of the sampling tube is provided with sampling scale lines. The plastic protective sleeve is a cylindrical transparent plastic film. This design makes it convenient for sampling personnel to visually judge the position of the sampling tube in the mortar and the extent of mortar entry into the sampling tube.

[0023] The plastic protective sleeve of this utility model is made of two transparent plastic films heat-sealed together, which is low in cost. When the sampling tube is inserted into the mortar for sampling, the two transparent plastic films of the plastic protective sleeve will not separate under pressure. After the sampling tube has finished sampling and is removed from the mortar, the sampling personnel can separate the two transparent plastic films by tearing, thereby peeling the plastic protective sleeve off the sampling tube. This is convenient to operate and reduces the probability of mortar on the outside of the plastic protective sleeve falling onto the surface of the sampling tube.

[0024] The bottom end face of the easy plug of this utility model is designed with two symmetrical inclined surfaces, and the intersection of the two inclined surfaces forms a tip. This structure allows the sampling tube to be evenly distributed during the process of penetrating the mortar, thus making it easier to control the movement direction of the sampling tube.

[0025] This invention features a handle on the sampling cylinder, making it easier for sampling personnel to apply force to push down and extract the sample cylinder.

[0026] The handle and sampling cylinder of this utility model are detachably connected, which makes it convenient to reuse the handle when sampling with another sampling cylinder, reducing sampling costs. The connection method of inserting the handle into the plug slot not only facilitates the installation and disassembly of the handle, but also fixes the top of the plastic protective cover, preventing the plastic protective cover from slipping down and losing its protective effect on the sampling cylinder when the sampling cylinder is lifted.

[0032] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0033] This embodiment provides a mortar sampler, such as Figure 1-4 As shown, it includes a sampling tube 1, a top end cap 5, a plastic protective sleeve 3, an easy plug 2, and a bottom end cap 6.

[0034] The sampling cylinder 1 is a transparent cylindrical structure. The top and bottom ends of the outer wall of the sampling cylinder 1 have a first external thread section and a second external thread section, respectively. A top end cap 5 covers the top of the sampling cylinder 1 and can be threadedly connected to the first external thread section. A sealing ring 501 is provided on the inner side of the top end cap 5 for sealing the connection with the first external thread section. A bottom end cap 6 covers the bottom of the sampling cylinder 1 and can be threadedly connected to the second external thread section. A plastic protective sleeve 3 is movably fitted onto the outside of the sampling cylinder 1. The bottom of the plastic protective sleeve 3 covers the second external thread section. An easy plug 2 is located at the bottom of the sampling cylinder 1. The top of the easy plug 2 is fitted onto the outside of the plastic protective sleeve 3 and is threadedly connected to the second external thread section of the sampling cylinder 1, thus fixing the bottom of the plastic protective sleeve 3 onto the sampling cylinder 1. The bottom end of the easy plug 2 has a pointed tip for easy insertion into mortar.

[0035] In this embodiment, to facilitate visual judgment by sampling personnel regarding the depth of the sampling cylinder 1 into the mortar and the extent of mortar penetration within the sampling cylinder 1, sampling scale lines are provided on the outer wall of the sampling cylinder 1, and the plastic protective sleeve 3 is a cylindrical transparent plastic film. For example... Figure 4 As shown, the plastic protective sleeve 3 includes a first transparent plastic film 301 and a second transparent plastic film 302. The two sides of the first transparent plastic film 301 and the second transparent plastic film 302 are heat-sealed together to form a cylindrical structure. The plastic protective sleeve 3 has low cost. When the sampling cylinder 1 is inserted into the mortar for sampling, the two transparent plastic films of the plastic protective sleeve 3 will not separate under pressure. After the sampling cylinder 1 has finished sampling and is removed from the mortar, the sampling personnel can separate the two transparent plastic films by tearing, thereby peeling the plastic protective sleeve 3 off the sampling cylinder 1. This is convenient to operate and can reduce the probability of mortar on the outside of the plastic protective sleeve 3 falling onto the surface of the sampling cylinder.

[0036] In this embodiment, the bottom end face of the easy plug 2 includes two symmetrical inclined surfaces. The inclined surfaces are inclined from top to bottom towards the central axis of the easy plug 2. The intersection of the two inclined surfaces at the bottom of the easy plug 2 forms a tip. This structure allows the sampling tube to be evenly distributed during the process of penetrating the mortar, thereby making it easier to control the movement direction of the sampling tube. To facilitate the sampling personnel in pushing down and lifting the sample cylinder, two symmetrical handles 4 are provided on both sides of the top of the sampling cylinder 1. The handles 4 are located below the first external thread section. To improve the utilization rate of the handles, reduce sampling costs, and facilitate the later storage and transportation of the sampling cylinder, both handles 4 are detachably connected to the sampling cylinder 1. The outer wall of the sampling cylinder 1 has two connecting protrusions 101 that correspond one-to-one with the handles. Each connecting protrusion 101 has an insertion groove on its end face. The top of the plastic protective sleeve 3 covers the insertion groove. The two handles 4 are respectively inserted into the insertion grooves of the corresponding connecting protrusions 101, and the plastic protective sleeve 3 is pressed into the insertion groove for fixation. The handles 4 adopt the insertion groove connection method, which not only facilitates the installation and removal of the handles 4, but also fixes the top of the plastic protective sleeve 3, preventing the plastic protective sleeve 3 from slipping down and losing its protective effect on the sampling cylinder 1 during the lifting process.

[0037] Working principle: Before sampling, the sampler first places the plastic protective sleeve 3 on the outside of the sampling cylinder 1. The two sides of the plastic protective sleeve 3 cover the second threaded section and the insertion slot of the connecting protrusion 101, respectively. First, the easy plug 2 is installed to fix the bottom of the plastic protective sleeve 3 onto the sampling cylinder 1. Then, the two handles 4 are inserted into the insertion slots to fix the top of the plastic protective sleeve 3. At this time, the top end cap of the sampling cylinder 1 is not installed and is in an open state. Figure 1 As shown; sampling begins. The sampling personnel push the lower part of the sampling cylinder 1 into the mortar using the handle 4. The mortar within the movement trajectory of the sampling cylinder 1 enters the cylinder to become a mortar sample. After sufficient sample volume is collected, the top end cap 5 is threadedly installed on the first threaded section at the top of the sampling cylinder 1. Figure 2 As shown, when the sampling cylinder 1 is pulled out, the pressure inside and outside the sampling cylinder 1 is the same both during and after the pulling process, ensuring that the mortar sample remains well inside the sampling cylinder 1. During the sampling process, the outer wall of the sampling cylinder is protected by a plastic protective sleeve 3, and the mortar adheres to the plastic protective sleeve 3. After sampling is completed, the easy plug 2 is removed, the plastic protective sleeve 3 is torn off and detached from the sampling cylinder, and the bottom end cap 6 is installed on the second threaded section at the bottom of the sampling cylinder 1, as shown. Figure 3 As shown, this design prevents contamination and accidental spillage of the mortar near the bottom of the sampling tube during transportation. The entire process ensures the sampling tube surface remains clean, eliminating the need for washing and thus effectively protecting the performance of the mortar sample.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
