Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a sample preservation device for engineering testing. Background Technology

[0002] The sample retention and preservation device for engineering testing is a key piece of equipment for properly preserving various test samples in the engineering quality testing process.

[0003] Existing technologies, such as the utility model with publication number CN218369036U, disclose a sample retention device for engineering testing, including a support frame and multiple storage components; the multiple storage components are installed at intervals along the vertical direction on the support frame, and multiple sample retention areas are distributed on the storage components; it also includes a timer and an alarm that are arranged one-to-one with the sample retention areas, and the timer and the alarm are respectively connected to a controller.

[0004] Currently, most sample preservation devices adopt a rack-type structure, where samples are often placed directly on the rack. This results in a compact and cluttered arrangement, making it difficult to stably and quickly store and retrieve samples, which affects the normal use of the equipment. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing sample preservation devices, which mostly adopt rack-type structures, often placing samples directly on the rack. This results in compact and messy placement, making it difficult to stably and quickly store and retrieve samples, thus affecting the normal use of the equipment. Therefore, this invention proposes a sample preservation device for engineering testing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sample preservation device for engineering testing, comprising a box body, a partition fixedly connected to the inner wall of the box body, a sliding hole formed between the partition and the inner wall of the box body, and a drawer slidably connected in the sliding hole, a storage groove formed on the surface of the drawer, a control device provided on one side of the drawer, the control device comprising a positioning block, the positioning block fixedly connected to one side of the drawer, a positioning groove formed on the surface of the positioning block, a first guide roller rotatably connected to the inner wall of the positioning groove, a limit groove formed on the surface of the partition, a pull rope fixedly connected to the inner wall of the box body, the pull rope passing sequentially through the positioning groove and the limit groove, and the inner wall of the box body fixedly connected to... The cabinet features a limiting rack and auxiliary devices on its surface. The layered drawer design greatly facilitates sample management. Staff can store samples in the drawers according to different testing items, time sequences, and other standards. When a drawer is pulled, the drawer moves a positioning block, which in turn pulls a pull rope via a first guide roller. The rope moves within a limiting groove using the rotation of a second guide roller, keeping the rope taut. This ensures that when a sample is retrieved from one drawer, other drawers will not accidentally slide due to external vibrations or misoperation. In a laboratory environment with frequent personnel movement, this design effectively prevents collisions and interference between drawers, preventing sample damage and ensuring the safety of sample preservation and the orderly retrieval process.

[0007] Preferably, the number of drawers is five, and the five drawers are evenly spaced. This solution effectively avoids mutual interference between drawers, reduces the risk of damage to samples due to collisions, displacement, etc., and ensures the integrity of the retained samples.

[0008] Preferably, a second guide roller is rotatably connected inside the limiting groove to reduce wear on the pull rope.

[0009] Preferably, a magnet is fixedly connected to the inner wall of the limiting frame, and the magnet is magnetically attracted to one side of the drawer, which facilitates the positioning of the drawer.

[0010] Preferably, all drawers are located inside the cabinet, with the pull ropes in a bent and relaxed state. When any drawer is pulled out, the pull rope is in a taut state. This taut state restricts the accidental sliding of other drawers, ensuring that when a sample is taken from one drawer, the other drawers remain stable, avoiding mutual interference between drawers and ensuring the safety and orderliness of sample preservation.

[0011] Preferably, the auxiliary device includes a back panel, which is installed at the rear of the cabinet, and a handle is fixedly connected to the surface of the drawer, which can effectively move the drawer by pulling the handle.

[0012] Preferably, the lower surface of the box is fixedly connected with a support leg, and the surface of the support leg is provided with mounting holes. The support leg fixed on the lower surface of the box provides stable support for the device in various environments. Whether on an uneven ground at a construction site or on a laboratory bench, the support leg can ensure that the box is placed stably.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the layered drawer design greatly facilitates sample management. Staff can store samples in each drawer in an orderly manner according to different testing items, time sequence, and other standards. When a drawer is pulled out by pulling the handle, the drawer moves the positioning block. The first guide roller pulls the pull rope, which moves within the limiting groove with the help of the second guide roller, keeping the pull rope taut. This ensures that when a sample is taken from one drawer, other drawers will not accidentally slide due to external vibration, misoperation, or other factors. In a laboratory environment where personnel move frequently, this design can effectively avoid collisions and interference between drawers, prevent sample damage, and ensure the safety of sample preservation and the orderly process of retrieval.

[0015] In this invention, the fixed feet on the lower surface of the box provide stable support for the device in various environments. Whether on uneven ground at a construction site or on a laboratory bench, the feet can ensure that the box is placed stably.

[0016] This invention effectively avoids mutual interference between drawers, reduces the risk of sample damage caused by collisions, displacement, etc., and ensures the integrity of the retained samples. Attached Figure Description

[0024] Please see Figures 1-5 This utility model provides a technical solution: a sample preservation device for engineering testing, including a box 1. A partition 4 is fixedly connected to the inner wall of the box 1, forming a sliding hole between the partition 4 and the inner wall of the box 1, and a drawer 2 is slidably connected in the sliding hole. A storage groove 3 is opened on the surface of the drawer 2. A control device 5 is provided on one side of the drawer 2. The control device 5 includes a positioning block 51, which is fixedly connected to one side of the drawer 2. A positioning groove 56 is opened on the surface of the positioning block 51, and a first guide roller 52 is rotatably connected to the inner wall of the positioning groove 56. A limit groove 53 is opened on the surface of the partition 4. A pull rope 55 is fixedly connected to the inner wall of the box 1, and the pull rope 55 passes through the positioning groove 56 and the limit groove 53 in sequence. A limit frame 57 is fixedly connected to the inner wall of the box 1. The surface is equipped with auxiliary devices 6, and the layered drawer 2 design greatly facilitates sample management. Staff can store samples in each drawer 2 in an orderly manner according to different testing items, time sequence, and other standards. When a drawer 2 is pulled out by pulling the handle 61, the drawer 2 moves the positioning block 51, which pulls the pull rope 55 through the first guide roller 52. The pull rope 55 moves in the limiting groove 53 with the help of the rotation of the second guide roller 54, so that the pull rope 55 is taut. This ensures that when a sample is taken from a drawer 2, other drawers 2 will not slide accidentally due to external vibration, misoperation, or other factors. In the laboratory environment, where personnel move around frequently, this design can effectively avoid mutual collision and interference between drawers 2, prevent sample damage, and ensure the safety of sample preservation and the orderly process of retrieval.

[0025] In this embodiment, there are five drawers 2, which are evenly spaced. This solution effectively avoids mutual interference between drawers 2, reduces the risk of damage to the samples due to collisions, displacement, etc., and ensures the integrity of the retained samples.

[0026] Specifically, the inner rotatable connection of the limiting groove 53 is a second guide roller 54, which reduces the wear of the pull rope 55.

[0027] Specifically, a magnet 58 is fixedly connected to the inner wall of the limiting frame 57. The magnet 58 is magnetically attracted to one side of the drawer 2, which facilitates the positioning of the drawer 2.

[0028] In this embodiment: all drawers 2 are located in the box 1, the pull rope 55 is in a bent and relaxed state, and after any drawer 2 is pulled out, the pull rope 55 is in a taut state. This taut state plays a role in restricting the accidental sliding of other drawers 2, ensuring that when a sample is taken from one drawer 2, the other drawers 2 remain stable, avoiding mutual interference between drawers 2, and ensuring the safety and orderliness of sample preservation.

[0029] Specifically, the auxiliary device 6 includes a back panel 64, which is installed at the rear of the cabinet 1. A handle 61 is fixedly connected to the surface of the drawer 2, and pulling the handle 61 can effectively move the drawer 2.

[0030] Specifically, the lower surface of the housing 1 is fixedly connected with a support leg 62, and the surface of the support leg 62 is provided with mounting holes 63. The support leg 62 fixed on the lower surface of the housing 1 provides stable support for the device in various environments. Whether on the uneven ground of the construction site or on the experimental table of the laboratory, the support leg 62 can ensure that the housing 1 is placed stably.

[0031] Working principle: The sampling layered drawer design enables classified storage of samples, allowing staff to store and manage samples in an orderly manner according to different testing items, time sequence, etc., thus improving the efficiency of sample retrieval.

[0032] When a sample needs to be retrieved from drawer 2, pulling out handle 61 pulls drawer 2 out. Drawer 2 moves positioning block 51, which in turn pulls pull rope 55 via first guide roller 52. Pull rope 55 moves within limiting groove 53 as second guide roller 54 rotates. Since pull rope 55 connects each drawer 2 sequentially, it remains taut when any drawer 2 is pulled out. This tautness prevents other drawers 2 from sliding accidentally, ensuring that other drawers 2 remain stable while a sample is being retrieved from one drawer 2. This avoids mutual interference between drawers 2 and guarantees the safety and orderliness of sample storage. After the sample is stored, simply push drawer 2 back to its original position. Then, magnet 58 attracts drawer 2, completing its positioning.

[0033] The support legs 62 fixed on the lower surface of the housing 1 provide stable support for the housing 1. The mounting holes 63 on the surface of the support legs 62 can be used to further fix the housing 1 to the ground or other support surfaces, ensuring that the device can be placed stably in different environments and ensuring the stability of the sample preservation environment. At the same time, when inspecting the equipment, only the back plate 64 needs to be removed to observe the internal structure of the equipment, which greatly reduces the workload of maintenance personnel and improves the service life of the equipment.
