Description

Technical Field

[0001] This utility model belongs to the field of storage cabinet technology, specifically a multi-pin type storage cabinet. Background Technology

[0002] Needles are commonly used operating tools and often need to be stored and managed in multiple units according to actual needs. In the clinical departments of hospitals, injection needles and blood collection needles of different specifications need to be classified and stored according to usage frequency and function so that medical staff can quickly access them and ensure the efficient progress of the diagnosis and treatment process. Therefore, there is an urgent need in the market for a multi-needle storage cabinet.

[0003] Existing multi-needle storage devices often have fixed-size fixing structures, which cannot flexibly adjust the clamping force according to needles of different diameters and sizes. This results in fine needles being easily shaken and displaced, while coarse needles are difficult to insert or get stuck. In addition, the opening and closing of the needle fixing structure mostly relies on traditional buckles or pins. When closing, it is easy to accidentally open due to loose fastening. Opening also requires force to pry or pull, which is cumbersome and easily causes structural wear.

[0004] Therefore, a multi-pin type storage cabinet is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a multi-needle storage cabinet, which solves the problem that existing devices cannot adapt to various needles of different thicknesses. When opening, the upper shell can be opened by simply pushing the upper shell upward through the finger groove, and the locking bead can be squeezed to release the locking block from the groove again without additional force, making the opening and closing of the upper shell more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-needle storage cabinet, comprising a storage cabinet body, wherein a plurality of needle storage drawers are slidably connected to the inner surface of the storage cabinet body via a slide rail assembly, and a plurality of needle fixing assemblies are embedded in the inner surface of each of the needle storage drawers, wherein each needle fixing assembly includes a fixed lower shell, which is embedded in the needle storage drawers, and a fixed upper shell is rotatably connected to one side of the top of the fixed lower shell, wherein a needle placement groove is provided at the top of the fixed lower shell, and two lower positioning blocks are fixedly connected to the inner surface of the needle placement groove, and two guide rods are slidably connected to the inner surface of the fixed upper shell, wherein two upper positioning blocks are fixedly connected to one end of each of the two guide rods, and a return spring is wound around the outer surface of each of the two guide rods.

[0007] Preferably, each of the two lower positioning blocks has a needle fixing groove at one end corresponding to the two upper positioning blocks.

[0008] Preferably, an anti-detachment block is fixedly connected to the top of each of the two guide rods.

[0009] Preferably, the top end of the return spring is fixedly connected to the upper inner wall of the fixed upper shell, and the bottom end of the return spring is fixedly connected to the top end of the upper positioning block.

[0010] Preferably, the needle fixing assembly further includes a snap-fit ​​groove formed at the top of the fixed lower shell. Two snap-fit ​​rods are fixedly connected to the lower inner wall of the snap-fit ​​groove. A snap-fit ​​spring is fixedly connected to one side inner wall of each of the two snap-fit ​​rods. A snap-fit ​​block is fixedly connected to one end of each of the two snap-fit ​​springs. The two snap-fit ​​blocks are slidably connected to the two snap-fit ​​rods respectively. A snap-fit ​​bead that cooperates with the two snap-fit ​​blocks is fixedly connected to the bottom end of the fixed upper shell. Two grooves that cooperate with the snap-fit ​​blocks are formed on the outer surface of the snap-fit ​​bead.

[0011] Preferably, the snap-fit ​​block is hemispherical and the snap-fit ​​bead is spherical.

[0012] Preferably, the outer surface of the snap-fit ​​block is fixedly connected to two limiting blocks, and the inner surface of the snap-fit ​​rod is provided with a limiting groove for use with the two limiting blocks.

[0013] Preferably, one end of the needle storage drawer is provided with a finger groove, and the number of finger grooves is the same as the number of fixed upper shells.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a needle fixing component, when the upper housing is closed, the return spring can generate elastic deformation as the upper positioning block moves downward. Its rebound force can adaptively adjust the clamping distance between the upper and lower positioning blocks, thereby adapting to needles of different thicknesses. This avoids the shaking of fine needles due to loose clamping and prevents the difficulty in picking up and putting down thick needles due to tight clamping, thus solving the problem that existing devices cannot adapt to needles of various thicknesses.

[0016] 2. This utility model, by setting a needle fixing component, when closing the fixed upper shell, the locking bead squeezes the locking block and compresses the locking spring. When the locking block and the groove of the locking bead are aligned, the locking spring resets and pushes the locking block into the groove, achieving quick closing and locking. When opening, it is only necessary to push the fixed upper shell upward with the finger groove, and the locking bead can squeeze the locking block out of the groove again without additional force, making the opening and closing of the fixed upper shell more convenient.

[0026] 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.

[0027] like Figures 1 to 5 As shown, this utility model provides a multi-needle storage cabinet, including a cabinet body 1. A plurality of needle storage drawers 2 are slidably connected to the inner surface of the cabinet body 1 via a slide rail assembly. A plurality of needle fixing components 3 are embedded in the inner surface of each of the needle storage drawers 2. Each needle fixing component 3 includes a lower fixing shell 31, which is embedded in the needle storage drawers 2. A upper fixing shell 32 is rotatably connected to one side of the top of the lower fixing shell 31. A needle placement groove 312 is provided at the top of the lower fixing shell 31 for placing needles. Two lower positioning blocks 313 are fixedly connected to the inner surface of the groove 312, and two guide rods 323 are slidably connected to the inner surface of the fixed upper shell 32. Two upper positioning blocks 321 are fixedly connected to one end of each guide rod 323, and a return spring 324 is wound around the outer surface of each guide rod 323. Through the cooperation of the lower positioning blocks 313 and the upper positioning blocks 321, combined with the guide rods 323 and the return springs 324, a stable clamping can be formed for needles of different thicknesses, improving the adaptability of the device to needles of various specifications.

[0028] Specifically, each of the two lower positioning blocks 313 and the two upper positioning blocks 321 has a needle fixing groove 322 at one end. The needle fixing groove 322 can fit and limit the needle with the outer wall, further restricting the lateral sway of the needle on the basis of longitudinal clamping, and enhancing the stability of needle fixing.

[0029] like Figures 1 to 5 As shown, anti-detachment blocks 325 are fixedly connected to the top of both guide rods 323. The anti-detachment blocks 325 can effectively prevent the guide rods 323 from slipping out of the fixed upper shell 32, ensuring the stability of the guide rods 323 during the sliding process and avoiding positioning failure caused by component detachment.

[0030] Furthermore, the top end of the return spring 324 is fixedly connected to the upper inner wall of the fixed upper shell 32, and the bottom end of the return spring 324 is fixedly connected to the top end of the upper positioning block 321. The fixed method of the two ends of the return spring 324 ensures that it can generate a stable elastic clamping force when the fixed upper shell 32 is closed, and at the same time, it can drive the upper positioning block 321 to automatically reset when it is opened, thus improving the ease of operation.

[0031] like Figures 1 to 5 As shown, the needle fixing assembly 3 also includes a snap-fit ​​groove 33 on the top of the fixed lower shell 31. Two snap-fit ​​rods 332 are fixedly connected to the lower inner wall of the snap-fit ​​groove 33. Snap-fit ​​springs 335 are fixedly connected to one side inner wall of each of the two snap-fit ​​rods 332. Snap-fit ​​blocks 333 are fixedly connected to one end of each of the two snap-fit ​​springs 335. The two snap-fit ​​blocks 333 are slidably connected to the two snap-fit ​​rods 332 respectively. A snap-fit ​​bead 331 that cooperates with the two snap-fit ​​blocks 333 is fixedly connected to the bottom of the fixed upper shell 32. Two grooves 337 that cooperate with the snap-fit ​​blocks 333 are formed on the outer surface of the snap-fit ​​bead 331. Through the cooperation of the snap-fit ​​blocks 333 and the grooves 337 of the snap-fit ​​bead 331, the fixed upper shell 32 can be quickly closed and stably locked. No additional tools are required for opening; it can be unlocked simply by pressing lightly, thus improving operational efficiency.

[0032] It is worth noting that the locking block 333 is hemispherical and the locking bead 331 is spherical. The hemispherical locking block 333 and the spherical locking bead 331 are matched in shape, making the locking and unlocking process smoother, reducing frictional wear between components, and extending the service life of the device.

[0033] like Figures 1 to 5 As shown, two limiting blocks 334 are fixedly connected to the outer surface of the snap-fit ​​block 333, and a limiting groove 336 is provided on the inner surface of the snap-fit ​​rod 332 to cooperate with the two limiting blocks 334. The cooperation between the limiting blocks 334 and the limiting groove 336 can limit the sliding stroke of the snap-fit ​​block 333, prevent the snap-fit ​​block 333 from slipping off the snap-fit ​​rod 332 due to excessive sliding, and ensure the stable operation of the snap-fit ​​structure.

[0034] It is worth emphasizing that one end of the needle storage drawer 2 is provided with several finger slots 311. The number of finger slots 311 is the same as the number of fixed upper shells 32. The number of finger slots 311 corresponds to the number of fixed upper shells 32, which makes it convenient for users to quickly locate and operate the corresponding fixed upper shells 32. At the same time, it is easy to pull out the needle storage drawer 2, which improves the overall ease of use.

[0035] Working principle and process: In use, pull out the needle storage drawer 2 through the finger groove 311, push the fixed upper shell 32 upward to make the locking bead 331 squeeze the locking block 333, compress the locking spring 335 and disengage it from the groove 337, thus opening the fixed upper shell 32; then put the needle into the needle placement slot 312, the lower positioning block 313 supports the needle, when the fixed upper shell 32 is closed, the upper positioning block 321 moves down with the guide rod 323, the return spring 324 is compressed to generate elastic force, which, together with the lower positioning block 313, clamps the needle, and the needle fixing groove 322 further restricts the shaking of the needle; at the same time, the locking bead 331 squeezes the locking block 333, when the groove 337 is aligned with the locking block 333, the locking spring 335 returns to its original position and pushes the locking block 333 into the groove 337, thus locking the fixed upper shell 32; when taking out the needle, repeat the pressing and unlocking steps, the return spring 324 drives the upper positioning block 321 to return to its original position, and the needle can be taken out.
