Description

Technical Field

[0001] This utility model relates to the field of sampling box technology, specifically a sampling box for pathogenic microorganisms in pigsty environment. Background Technology

[0002] As the core area for livestock and poultry farming, pigsties are a key factor in the spread of diseases due to pathogenic microorganisms in their environment. Studies have shown that aerosol particles in the air of pigsties can carry pathogens such as porcine reproductive and respiratory syndrome virus (PRRSV) and swine influenza virus, infecting pigs through the respiratory or digestive tract. In addition, microbial contamination on surfaces such as pigsty floors, pens, and feed troughs can expand the scope of infection through direct contact or indirect transmission. Therefore, sampling for pathogenic microorganisms is particularly necessary.

[0003] A search revealed a utility model patent with Chinese patent publication number CN214241830U, which discloses a multifunctional pathogenic microorganism sampling box, including a box body. The bottom of the box body has an installation groove, and a bearing is installed in the installation groove. A second threaded rod is installed on the inner ring of the bearing. A second internal threaded sleeve is threaded onto the second threaded rod, and a bearing plate is fixedly sleeved on the outer wall of the second internal threaded sleeve.

[0004] In order to ensure that the container holding the sample can be completely sealed when the above device is in use, the support tray needs to be set at the bottom of the box. Therefore, the upper edge of the box will obstruct the operation during the process of taking the container out and putting it in, making it inconvenient to operate and leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a pigsty environment pathogen sampling box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pigsty environmental pathogen sampling box, comprising a box body, a box cover rotatably connected to the top of the box body via a hinge, the box body and the box cover being fixedly connected to the same latch, a storage rack slidably connected inside the box body, and a lifting assembly fixedly connected inside the box body. The lifting assembly includes a fixing plate fixedly connected inside the box body, the fixing plate being located on the side of the box body near the top, a guide wheel rotatably connected to the middle of one outer wall of the fixing plate and the other inner wall of the box body, an elastic rope fixedly connected to the middle of both sides of the top outer wall of the storage rack, the two elastic ropes respectively contacting the two guide wheels, and one top end of each of the two elastic ropes being fixedly connected to the outer wall of the box cover near the box body, a limiting structure fixedly connected to the outside of the box body, and four storage compartments opened inside the storage rack, with the same fixing assembly fixedly connected inside the four storage compartments.

[0007] When the lid is opened, the storage rack automatically slides upwards, making it easy to pick up and put down containers. When the lid is closed, the container can be fully inserted into the box. Opening the lid's latch and flipping it upwards causes the upper end of the elastic rope to move upwards simultaneously. Supported by the guide wheels, the lower end of the elastic rope remains vertical, ensuring a constant force direction on the storage rack and improving its stability during movement. The lower end of the elastic rope pulls the storage rack upwards, stopping when it contacts the two guide wheels, thus ensuring unobstructed container handling and making operation more convenient. Due to the elasticity of the elastic rope, the lid can continue to move upwards a certain distance during the opening process.

[0008] As a further preferred embodiment of this technical solution, the limiting structure includes a mounting sleeve fixedly connected to the top of one side of the box body, a horizontally arranged limiting rod slidably connected to the inner wall of one side of the mounting sleeve, the limiting rod contacting the side wall of the box cover, the limiting rod and the mounting sleeve being fixedly connected to the same spring, and a driving component being fixedly connected to the bottom of the limiting rod.

[0009] As a further preferred embodiment of this technical solution, the driving component includes an extension piece fixedly connected to one end of the limiting rod located inside the mounting sleeve, and the bottom inner wall of the mounting sleeve is provided with an avoidance groove adapted to the extension piece.

[0010] As a further preferred embodiment of this technical solution, the fixing assembly includes sixteen airbags fixedly connected to the four corners of the four storage compartments. Two horizontally arranged main air outlet pipes are fixedly connected to one side of the bottom of the storage rack. Four auxiliary air outlet pipes are fixedly connected to the outside of the two main air outlet pipes respectively. Two connectors are fixedly connected to the top of each of the eight auxiliary air outlet pipes. The sixteen connectors are respectively connected to the sixteen airbags. An air supply structure is fixedly connected inside the box.

[0011] As a further preferred embodiment of this technical solution, the gas supply structure includes a cavity fixedly connected to one side of the inner wall of the bottom of the box, a piston slidably connected inside the cavity, an extension rod in the shape of a letter fixedly connected to the middle position of the outer wall of the top of the piston, and a pressure ring of the box cover near the outer wall of the box, the pressure ring being located below the horizontal portion of the extension rod.

[0012] When the lid is flipped downwards, the externally fixed pressure ring is moved downwards synchronously. Then, the end of the pressure ring contacts the top wall of the piston, and the piston will be squeezed and moved downwards along the inner wall of the tube. The air inside the tube is squeezed into the two main exhaust pipes, and then enters the eight auxiliary exhaust pipes through the two main exhaust pipes respectively. Finally, it enters the sixteen air bladders through the auxiliary exhaust pipes, and the air bladders can begin to inflate. Each set of four air bladders can securely clamp the sample container according to its size and shape.

[0013] As a further preferred embodiment of this technical solution, the connection between the main exhaust pipe and the cavity is made of a corrugated telescopic tube.

[0014] As a further preferred embodiment of this technical solution, two reinforcing ribs are fixedly connected to the top outer wall of the extension rod.

[0015] This utility model provides a pigsty environment pathogenic microorganism sampling box, which has the following beneficial effects: (1) By setting up a lifting component, this utility model can drive the storage rack to slide upward automatically when the lid is opened, so that the container can be easily picked up and put down. When the lid is closed, the container can also be completely put into the box. When the lid is opened and flipped upward, the lid drives the upper end of the elastic rope to move upward synchronously. Under the support of the guide wheel, the lower end of the elastic rope will remain vertical, thus ensuring that the force direction of the storage rack is constant, which is conducive to improving the stability of the storage rack when moving. The lower end of the elastic rope pulls the storage rack upward. When the storage rack contacts the two guide wheels, it stops moving, so that the subsequent container picking and putting process is no longer obstructed and the operation is more convenient. Since the elastic rope has elasticity, the lid can continue to move upward a certain distance during the opening process.

[0016] (2) By setting a fixing component, when the box cover is flipped down, the externally fixed pressure ring is driven to move down synchronously. Then the end of the pressure ring contacts the top wall of the piston, and the piston will be squeezed down along the inner wall of the tube. The air inside the tube is squeezed into the two main exhaust pipes, and then enters the eight auxiliary exhaust pipes through the two main exhaust pipes respectively. Finally, it enters the sixteen air bags through the auxiliary exhaust pipes, and the air bags can start to expand and grow. Each four air bags can be used to firmly clamp the sample container according to its size and shape. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 2 As shown in Figure 4, in this embodiment, a pigsty environmental pathogen sampling box includes a box body 1. A box cover 2 is rotatably connected to the top of the box body 1 via a hinge. The box body 1 and the box cover 2 are fixedly connected to the same latch (preferably a stainless steel duckbill latch). A storage rack 5 is slidably connected inside the box body 1. A lifting assembly 3 is fixedly connected inside the box body 1. The lifting assembly 3 includes a fixing plate 301 fixedly connected inside the box body 1. The fixing plate 301 is located on the side of the box body 1 near the top. A latch is rotatably connected to the middle of one outer wall of the fixing plate 301 and the other inner wall of the box body 1. Each guide wheel 302 has an elastic rope 303 (preferably made of polyester fiber + rubber core material) fixedly connected to the middle of both sides of the top outer wall of the storage rack 5. The elastic rope 303 is combined with high-strength fiber and rubber elasticity, taking into account both tensile strength and durability, and is suitable for lifting heavy objects. The two elastic ropes 303 are in contact with the two guide wheels 302 respectively. The top end of each elastic rope 303 is fixedly connected to the outer wall of the box cover 2 near the box body 1. The box body 1 is fixedly connected to the outside of the box body 1. The storage rack 5 has four storage compartments inside, and the same fixing component 4 is fixedly connected inside the four storage compartments.

[0020] Open the latch of the lid 2 and flip it upward. The lid 2 moves the upper end of the elastic rope 303 upward in sync. With the support of the guide wheel 302, the lower end of the elastic rope 303 will remain vertical, thus ensuring that the force direction of the storage rack 5 is constant. This helps to improve the stability of the storage rack 5 when it moves. The lower end of the elastic rope 303 pulls the storage rack 5 upward. When the storage rack 5 contacts the two guide wheels 302, it stops moving, so that the subsequent container loading and unloading process is no longer obstructed and the operation is more convenient. Because the elastic rope 303 has elasticity, the lid 2 can continue to move upward a certain distance during the opening process.

[0021] The limiting structure includes a mounting sleeve 304 fixedly connected to the top of one side of the housing 1. A horizontally set limiting rod 305 is slidably connected to the inner wall of one side of the mounting sleeve 304. The limiting rod 305 contacts the side wall of the housing cover 2. The same spring 306 is fixedly connected between the limiting rod 305 and the mounting sleeve 304. A driving component is fixedly connected to the bottom of the limiting rod 305.

[0022] The driving component includes an extension piece 307 fixedly connected to one end of the limiting rod 305 located inside the mounting sleeve 304, and an avoidance groove adapted to the extension piece 307 is provided on the bottom inner wall of the mounting sleeve 304.

[0023] Since the limiting rod 305 cannot extend when the lid 2 is in contact with its outer wall when it is sealing the opening of the box body 1, as the lid 2 is flipped open, the lid 2 moves to the side of the limiting rod 305, and the limiting rod 305 is no longer restricted. The originally stretched spring 306 can then drive the limiting rod 305 to block the lid 2, effectively preventing the lid 2 from being pulled back.

[0024] like Figure 2 and Figure 3 As shown, the fixing component 4 includes sixteen airbags 405 fixedly connected to the four corners of the four storage compartments. Two horizontally arranged main air outlets 403 are fixedly connected to one side of the bottom of the storage rack 5. Four auxiliary air outlets 404 are fixedly connected to the outside of the two main air outlets 403 respectively. Two connectors are fixedly connected to the top of each of the eight auxiliary air outlets 404. The sixteen connectors are respectively connected to the sixteen airbags 405. An air supply structure is fixedly connected inside the box 1.

[0025] The gas supply structure includes a cavity 401 fixedly connected to one side of the bottom inner wall of the box 1, a piston 402 slidably connected inside the cavity 401, an extension rod 407 in the shape of a number 7 fixedly connected to the middle position of the top outer wall of the piston 402, and a pressure ring 406 on the outer wall of the box cover 2 near the box 1, the pressure ring 406 being located below the horizontal part of the extension rod 407.

[0026] When the lid 2 flips downwards, the externally fixed pressure ring 406 is moved downwards synchronously. Then, the end of the pressure ring 406 contacts the top wall of the piston 402, and the piston 402 is squeezed and moved downwards along the inner wall of the cavity 401. The air inside the cavity 401 is squeezed into the two main exhaust pipes 403, and then enters the eight auxiliary exhaust pipes 404 through the two main exhaust pipes 403 respectively. Finally, it enters the sixteen air bladders 405 through the auxiliary exhaust pipes 404, and the air bladders 405 can begin to inflate. Each four air bladders 405 can firmly clamp the sample container according to its size and shape. When the lid 2 flips upwards, the lid 2 drives the pressure ring 406 to contact the extension rod 407. Then, the pressure ring 406 can lift the piston 402 upwards through the extension rod 407. The piston 402 can then draw the air back into the air bladders 405 through the cavity 401 to avoid affecting the handling of the container.

[0027] like Figure 3 As shown, the connection between the main exhaust pipe 403 and the cavity 401 is made of a corrugated telescopic tube, so that when the storage rack 5 moves the main exhaust pipe 403 upward, the unfixed corrugated telescopic tube can extend and retract without affecting the movement of the storage rack 5.

[0028] like Figure 3 As shown, two reinforcing ribs are fixedly connected to the top outer wall of the extension rod 407, which helps to improve the overall strength of the extension rod 407 and prevents it from deforming during use.

[0029] This utility model provides a pigsty environmental pathogen sampling box, the specific working principle of which is as follows: When the device is working, the latch of the lid 2 is opened and flipped upwards. The lid 2 drives the upper end of the elastic rope 303 to move upwards synchronously. Under the support of the guide wheel 302, the lower end of the elastic rope 303 will remain vertical, thus ensuring that the force direction of the storage rack 5 is constant, which helps to improve the stability of the storage rack 5 when moving. The lower end of the elastic rope 303 pulls the storage rack 5 upwards. When the storage rack 5 contacts the two guide wheels 302, it stops moving, so that the subsequent container loading and unloading process is no longer obstructed, and the operation is more convenient. Because the elastic rope 303 has elasticity, the lid 2 can continue to move upwards a certain distance during the opening process. Since the limit rod 305 cannot extend when the lid 2 is in contact with its outer wall when it is sealing the opening of the box body 1, as the lid 2 flips open, the lid 2 moves to the side of the limit rod 305. The limit rod 305 is no longer restricted, and the originally stretched spring 306 can drive the limit rod 305 to block the lid 2, effectively preventing the lid 2 from being pulled back.

[0030] Next, place the container containing the collected microbial samples into the storage rack compartment 5. The samples include sterile swab preservation solution tubes, sterile buffer solution tubes, fecal glass bottles, and liquid impact bottles. Pull the limiting rod 305 to release it from the lid 2, and flip the lid 2 in the opposite direction to cover the opening of the box body 1. The storage rack 5 will also fall back to the bottom of the box body 1 under the action of gravity as the elastic rope 303 moves. When the lid 2 flips downward, the externally fixed pressure ring 406 is moved downward synchronously. Then, the end of the pressure ring 406 contacts the top wall of the piston 402, and the piston 402 will be squeezed and moved downward along the inner wall of the tube 401. The air inside the tube 401 The sample is squeezed into two main exhaust pipes 403, then into eight secondary exhaust pipes 404, and finally into sixteen air bladders 405. The air bladders 405 then begin to inflate. Each set of four air bladders 405 can securely hold the sample container according to its size and shape. When the lid 2 flips upward, it causes the pressure ring 406 to contact the extension rod 407. The pressure ring 406 then lifts the piston 402 upward through the extension rod 407. The piston 402 then draws the air out of the air bladders 405 through the tube 401, thus avoiding interference with the handling of the container.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
