Description

Technical Field

[0001] This utility model relates to the field of storage rack technology, specifically an adjustable storage rack for a glove box. Background Technology

[0002] In laboratories, pharmaceutical manufacturing, and precision manufacturing, glove boxes are commonly used closed operating devices for handling sensitive materials in inert gas or sterile environments. Glove boxes are typically equipped with shelves to store laboratory equipment, samples, or other items. However, most existing shelves are fixed structures, which present the following problems:

[0003] Traditional shelving units have fixed tray positions, requiring operators to frequently adjust their body posture or move their arms to retrieve items from different locations, which can easily lead to fatigue over long periods of operation.

[0004] Glove boxes come in various sizes, and operators have different arm lengths, so fixed shelves cannot meet individual needs and affect operational efficiency.

[0005] Existing adjustable shelves cannot achieve precise positioning of items, making it difficult to quickly move target items to the optimal position for glove operation. Utility Model Content

[0011] In a further embodiment, the perforated plate is connected to the inner wall of the glove box by screws, and the support frame is detachably connected to the perforated plate by a snap-fit ​​structure.

[0012] In a further embodiment, the support frames on the three perforated plates are synchronously linked by the light rod and chain to form an overall motion structure.

[0013] In a further embodiment, the first slider is slidably engaged with the groove, the first gear is movably connected to the support frame via a bearing, and the secondary sprocket is fixedly connected to the first gear.

[0014] In a further embodiment, the main sprocket is sleeved on the optical rod, the main sprocket and the optical rod are interference-fitted, and the optical rod and the support frame are clearance-fitted; the output gear of the second motor drives the optical rod to rotate.

[0015] In a further embodiment, the guide groove is connected to the first slider by screws, and the second slider is slidably engaged with the guide groove; the tray is connected to the second slider by screws.

[0016] Beneficial effects: This utility model discloses an adjustable storage rack for glove boxes. The utility model uses a snap-fit ​​connection between the perforated plate and the support frame to adapt to glove boxes of different sizes. The position of the support frame is adjustable, further expanding the adjustment range.

[0029] This utility model provides an adjustable shelf for a glove box, enabling precise adjustment of the tray in the front-to-back (Y-axis) and left-to-right (X-axis) directions, allowing the operator to easily retrieve items. The specific implementation details of the solution are described below.

[0030] Reference Figures 1-11 As shown, an adjustable shelf for a glove box includes:

[0031] Glove box 1, shelf 2 installed inside the glove box 1;

[0032] The storage rack 2 includes three parallel perforated plates 21 mounted on the inner wall of the glove box 1. Support frames 22 on the three perforated plates 21 are synchronously linked by the guide rod 24 and chain 224 to form an integrated moving structure. The perforated plates 21 are connected to the inner wall of the glove box 1 by screws, and the surface of the perforated plates 21 is provided with support frames 22. The support frames 22 and the perforated plates 21 are detachably connected by a snap-fit ​​structure. The support frames 22 have grooves 225, and a first slider 226 is provided within the grooves 225. The first slider 226 slides within the grooves 225. A toothed groove 227 is provided on one side facing the inner side of the support frame 22. The toothed groove 227 meshes with a first gear 223 installed in the support frame 22. A secondary sprocket 222 is provided on the coaxial side of the first gear 223. The first gear 223 is movably connected to the support frame 22 through a bearing. The secondary sprocket 222 is fixedly connected to the first gear 223. A main sprocket 221 is provided in the support frame 22. The main sprocket 221 is sleeved on the guide rod 24. The main sprocket 221 and the guide rod 24 are interference-fitted. The main sprocket 221 and the secondary sprocket 222 are connected by a chain 224.

[0033] Two parallel guide grooves 25 are provided above the first slider 226. The guide grooves 25 are connected to the first slider 226 by screws. A second slider 26 is provided inside the guide grooves 25, and the second slider 26 slides in cooperation with the guide grooves 25. A tray 23 is provided above the second slider 26, and the tray 23 is connected to the second slider 26 by screws. A rack 231 is provided at the bottom of the tray 23, and the rack 231 meshes with the output gear of the first motor 261 installed between the guide grooves 25. A through-passage between the three perforated plates 21 and the main sprocket 221 is provided. The support frame 22 has a light rod 24, which is clearance-fitted with the support frame 22. One end of the light rod 24 is equipped with a second motor 27 installed inside the support frame 22. The output gear of the second motor 27 drives the light rod 24 to rotate. The first motor 261 is used to drive the tray 23 to move along the set direction of the guide groove 25. The output gear of the second motor 27 drives the light rod 24 to rotate, causing the tray 23 to move along the set direction of the groove 225, thereby realizing the horizontal left, right and forward and backward movement of the tray 23, so that the items on the tray 23 are close to the operation position of the gloves.

[0034] Working principle: First, the second motor 27 starts, and its output gear drives the guide rod 24 to rotate. Since the main sprocket 221 is interference-fitted with the guide rod 24, the main sprocket 221 rotates synchronously when the guide rod 24 rotates. The main sprocket 221 drives the secondary sprockets 222 in each support frame 22 to rotate via the chain 224. The secondary sprockets 222 are coaxially fixed with the first gear 223, so the first gear 223 rotates accordingly. The first gear 223 meshes with the tooth groove 227 on the first slider 226, causing the first slider 226 to move along the groove 225 (Y-axis) of the support frame 22. Since the guide groove 25 is fixed on the first slider 226, and the tray 23 is mounted on the guide groove 25 via the second slider 26, the tray 23 moves synchronously (Y-axis) with the first slider 226.

[0035] Then, the first motor 261 starts, and its output gear meshes with the rack 231 at the bottom of the tray 23. When the gear rotates, the rack 231 drives the second slider 26 to slide in the guide groove 25. Since the tray 23 is fixed on the second slider 26, the tray 23 moves along the direction (X-axis) of the guide groove 25.

[0036] Since the three perforated plates 21 are linked by the guide rod 24 and the chain 224, when the second motor 27 drives the guide rod 24 to rotate, the main sprockets 221 in all the support frames 22 rotate synchronously, and drive their respective secondary sprockets 222 and first gears 223 through the chain 224; the trays 23 on the three perforated plates 21 will move synchronously (Y-axis) to ensure overall stability.

[0037] The perforated plate 21 is fixed to the inner wall of the glove box 1 with screws, and the installation spacing can be adjusted according to the size of the glove box 1.

[0038] The support frame 22 is connected to the perforated plate 21 by a snap-fit ​​connection, and the position of the support frame 22 on the perforated plate 21 can be adjusted to meet the needs of different depths.

[0039] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
