Description

Technical Field

[0001] This utility model relates to the field of oil test paper storage technology, specifically an oil test paper storage device. Background Technology

[0002] Oil test strips are a convenient tool for rapid semi-quantitative detection of oil indicators through chemical reaction and color development. Using paper as a carrier, they solidify chemical substances such as color developers, and the degree of color change reflects the content of the target substance. The results need to be compared with a standard color card. They are used to monitor the quality of edible oil and determine whether it is rancid. Engine oil test strips contain both chemical and electronic components, which can determine the degree of engine oil contamination and when to replace it. They are easy to operate. For example, edible oil test strips are inserted into the oil sample and removed within seconds, and then the color is compared on time. Engine oil test strips are dropped and the sample is allowed to stand for observation of the ring band.

[0003] Currently, when storing oil test strips, a storage device is needed to store the containers containing the test strips for easy retrieval later. However, when using a storage device to store a large number of oil test strips, if only a small amount is used at a time, some space will be left inside the storage device. When taking the test strips out of the storage device, the containers inside are prone to tipping over, resulting in the test strip containers being arranged in a messy manner, which affects the observation of the number of oil test strips stored.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a new technical solution:

[0026] Storage box 1 serves as the main frame of the device, with other components installed directly or indirectly inside / on its surface, providing basic storage space for oil test paper and container, and playing an overall protective role.

[0027] The door 2 is rotatably installed on the upper surface of the storage box 1. It can be opened and closed to seal the inside of the storage box 1, protect the test strips inside from external contamination, and facilitate the handling of taking out and putting in the test strips.

[0028] The observation window 3 is installed on the upper surface of the door 2 and is made of transparent material, so that the storage status and quantity of test paper containers inside the storage box 1 can be observed directly without opening the door 2;

[0029] The storage box 4 is fixedly installed on the lower inner wall of the storage box 1, with an opening at the top. It is the direct carrier for placing the container containing the oil test paper, and plays a preliminary role in storing and positioning the container.

[0030] The limiting top plate 5 is slidably installed inside the storage box 4. It is a rectangular plate or a rectangular plate with weight-reducing holes. Its core function is to limit and stabilize the container containing the test paper from the side to prevent the container from tipping over.

[0031] The top block 6 is slidably installed inside the rectangular groove 7 of the limiting top plate 5. After being driven downward by the screw 11, it contacts the lower inner wall of the storage box 4 and fixes the position of the limiting top plate 5 through friction.

[0032] A rectangular groove 7 is formed on the lower surface of the limiting top plate 5, providing the top block 6 with mounting space and motion guidance for sliding up and down;

[0033] There are two mounting slots 8, which are opened on the lower surface of the limiting top plate 5, for fixing the mounting roller 9 and providing a mounting carrier for the roller 9;

[0034] There are two rollers 9, which are rotatably installed inside the mounting groove 8. This reduces the friction between the limiting top plate 5 and other parts or containers in the storage box 4 when the limiting top plate 5 slides back and forth, making the adjustment of the limiting top plate 5 smoother.

[0035] The rubber pad 10 is fixedly installed on the lower surface of the top block 6 to increase the friction between the top block 6 and the lower inner wall of the storage box 4, improve the fixing stability of the limiting top plate 5, and avoid wear caused by hard contact.

[0036] The screw 11 is threadedly installed inside the threaded groove 12 of the limiting top plate 5, and its lower end is rotatably connected to the top block 6. By rotating, it can move up and down along the threaded groove 12, thereby driving the top block 6 to lift and lower.

[0037] The threaded groove 12 is formed on the upper surface of the limiting top plate 5, and its lower end communicates with the rectangular groove 7, providing a threaded installation fit structure for the screw 11, which is the basis for the screw 11 to realize lifting transmission.

[0038] A convex circular groove 13 is formed on the upper surface of the top block 6 for rotatably mounting the convex circular rod 14, restricting the axial displacement of the convex circular rod 14 while allowing its circumferential rotation.

[0039] The convex circular rod 14 is fixedly installed at the lower end of the screw 11 and rotatably installed inside the convex circular groove 13, so as to realize the rotatable connection between the screw 11 and the top block 6, ensuring that when the screw 11 rotates, it only drives the top block 6 to rise and fall, rather than rotating synchronously;

[0040] The limiting groove 15 is formed on the left and right inner walls of the storage box 4, providing sliding installation space for the limiting plate 16 and playing a guiding and limiting role in the movement of the limiting plate 16.

[0041] There are two limiting plates 16, which are slidably installed inside the limiting groove 15 and fixedly connected to the limiting top plate 5. They work with the limiting groove 15 to limit the sliding trajectory of the limiting top plate 5 and prevent it from shifting or falling off the storage box 4 during movement.

[0042] There are two guide rods 17, which are fixedly connected to the inner wall of the limiting groove 15 and slidably connected to the limiting plate 16, further enhancing the stability of the limiting plate 16 when sliding and ensuring that the movement of the limiting top plate 5 is more precise.

[0043] The drying box 18 is fixedly installed on the upper rear inner wall of the storage box 1. Desiccant can be placed inside to absorb moisture in the air inside the storage box 1, maintain a dry storage environment, and ensure the storage quality of the oil test paper.

[0044] Furthermore, open the door 2 of storage box 1, place the container containing the oil test paper into storage box 4, and adjust the sliding limit plate 5 and 9 according to the number and height of the containers. This reduces the difficulty of moving the limit plate 5, allowing it to be close to the side of the container. Rotate screw 11, which moves downward along threaded groove 12, causing convex rod 14 to rotate within the convex groove 13 of top block 6. This pushes top block 6 downward along rectangular groove 7 until the rubber pad 10 on the lower surface of top block 6 is in close contact with the lower inner wall of storage box 4. At this point, the limit plate 5 is fixed in its current position. The surface fits snugly against the container to limit its position. When the door 2 is closed, the drying box 18 inside the storage box 1 maintains a dry environment. The storage status of the test strip containers inside can be directly observed through the observation window 3. When taking out or putting in test strips, simply open the door 2. The containers will not tip over because they are fixed by the limiting top plate 5. If the number of containers changes, rotate the screw 11 in the opposite direction, and the top block 6 will rise and detach from the inner wall of the storage box, releasing the fixing of the limiting top plate 5. After sliding and adjusting its position, it can be fixed again. This allows staff to observe the number of oil test strip containers inside the storage device and replenish the oil test strip containers according to the observed number.

[0045] The sliding limiting top plate 5 moves in conjunction with the rollers 9 to accommodate different numbers of containers. The top block 6 is fixed in position by the screw drive. The rubber pad under the top block increases the friction with the inner wall of the storage box, improving the stability of the fixation. The limiting top plate 5 fits tightly against the container from the side, effectively preventing a large number of oil test paper containers inside the storage box from tipping over when it is taken out or put in, and making it convenient for staff to observe the number of oil test paper containers inside the storage device.

[0046] Example 1 (for reference) Figure 2 )

[0047] When the limiting top plate 5 is a rectangular plate, the complete plane of the rectangular plate can form a large area of ​​contact with the sides of multiple containers, forming a continuous and uniform lateral limiting force on the containers placed in rows. Even if the storage box 1 shakes during transportation, the containers are not easy to tip over or shift, preventing the test strips from scattering. The overall structural strength is high.

[0048] Example 2 (for reference) Figure 4 )

[0049] When the limiting top plate 5 is a rectangular plate with two weight-reducing holes on its front surface, the two weight-reducing holes effectively reduce the overall weight of the limiting top plate 5. When store staff pick up and put down the storage box 1 every day, they do not need to bear the burden of the top plate's own weight, reducing the fatigue of handling, which is especially suitable for high-frequency picking and putting down scenarios.

[0050] 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.
