[0002] In the field of mechanical manufacturing and maintenance, gears as an important transmission component, its storage and display mode directly affects the protection and management efficiency of gears. The traditional gear placement method usually adopts hanging or placing on the support to carry out display, storage and exhibition. However, this traditional method has obvious shortcomings:

[0003] On the one hand, due to the large weight of the gear itself, and no effective fixed connection with the support when hanging, the gear is prone to shaking or moving when subjected to slight external force (such as vibration, collision, etc.). This condition not only affects the neat arrangement of the gear, but also may cause physical damage to the gear itself, such as gear surface wear, deformation, etc., thereby affecting its performance and service life; on the other hand, unstable gear placement increases the risk of accidental falling, especially in the case of multi-layer stacking, once the bottom gear is displaced, it may cause the collapse of the entire stacked structure, bringing potential safety threat to the surrounding environment.

[0022] ​Frame 1, threaded rod 11, handwheel 12, sliding rod 13, limiting groove 14, self-locking caster wheel 15, placement plate 2, strip opening 21, limiting rod 22, top plate 3, top protrusion 31, limiting block 32, reinforcing rib sleeve 33, inner clamping block 4, clamping section 41, arc-shaped rubber protrusion 411, ejection section 42, gear 5. Detailed Implementation

[0023] like Figures 1-4 As shown, a gear placement rack includes a frame 1 and an ejector assembly. A plurality of placement plates 2 are fixedly disposed on the frame 1, and a plurality of clamping units are arrayed on the placement plates 2. The clamping units are opened by the ejector assembly to clamp the inner hole of the gear 5. The ejector assembly is disposed below each placement plate 2 and includes a top plate 3. The top plate 3 is slidably connected to the frame 1, and a top protrusion 31 is provided on the top plate 3 corresponding to the clamping unit. The top plate 3 is moved up and down by a moving assembly to open the clamping unit.

[0024] By employing the above technical solution, several placement plates 2 fixed on the frame 1 and clamping units arrayed thereon, in conjunction with the ejection assembly, clamp the inner hole of the gear 5, ensuring that the gear 5 will not shake or shift due to its own weight or external vibration after placement, effectively avoiding the risk of damage to the gear 5. The top plate 3 in the ejection assembly is slidably connected to the frame 1, and the clamping unit is opened by the up-and-down movement of the moving component. This not only achieves stable fixation of the gear 5 but also facilitates quick loading and unloading of the gear 5, improving operational efficiency. The overall design solves the problems of poor stability and low safety of traditional gear 5 placement racks, providing a safe and reliable storage environment for the gear 5, while simplifying management and retrieval processes, greatly improving work efficiency and operational convenience.

[0025] As a preferred embodiment, the placement plate 2 has several slots 21, and a limiting rod 22 is fixedly installed inside each slot 21. The clamping unit includes two opposing inner clamping blocks 4, each inner clamping block 4 including a clamping section 41 and an ejector section 42 inclined below the clamping section 41. The clamping section 41 is slidably sleeved on the limiting rod 22. The top protrusion 31 has an isosceles trapezoidal cross-section, and the top of the top protrusion 31 abuts against the opposing surfaces of the two ejector sections 42. The limiting rod 22 ensures that the two inner clamping blocks 4 move relative to each other during the ejection of the top protrusion 31, clamping the inner hole of the gear 5. To prevent rotation of the inner clamping blocks 4, the limiting rod 22 is preferably polygonal, such as... Figure 3 The square in the middle.

[0026] As a preferred embodiment, the movable component includes a threaded rod 11 rotatably mounted on the frame 1, and a threaded hole is provided at one end of the top plate 3 for threaded connection with the threaded rod 11. Since the top plate 3 is slidably connected to the frame 1, it achieves a limiting position, and the top plate 3 moves up and down by rotating the threaded rod 11 in both directions.

[0027] As a preferred scheme, the frame body 1 is provided with a sliding rod 13 on one side of the threaded rod 11, and the other end of the top plate 3 is in sliding connection with the sliding rod 13.

[0028] As a preferred scheme, the top plate 3 is provided with a limiting block 32 on both sides, the frame body 1 is provided with a limiting groove 14 matched with the limiting block 32, and the length of the limiting groove 14 is matched with the height of the top convex 31. Through the setting of the limiting groove 14 and the limiting block 32, the excessive ejection is prevented, and the adjustment is facilitated.

[0029] As a preferred scheme, the clamping section 41 is provided with a plurality of arc-shaped rubber protrusions 411 on the side close to the inner hole of the gear 5. The setting of the arc-shaped rubber protrusions 411 provides buffering and friction at the same time, and prevents hard contact with the inner hole of the gear 5.

[0030] As a preferred scheme, the top plate 3 is fixedly provided with a reinforcing rib sleeve 33 at the threaded hole, and the reinforcing rib sleeve 33 is in threaded connection with the threaded rod 11. The setting of the reinforcing rib sleeve 33 ensures the stability of the connection force. The reinforcing rib sleeve 33 can also be arranged on the side of the top plate 3 of the sliding rod 13, and a threaded hole does not need to be arranged, as shown in Figure 2 .

[0031] As a preferred scheme, the threaded rod 11 is provided with a hand wheel 12 at the bottom. The setting of the hand wheel 12 facilitates the rotation of the threaded rod 11.

[0032] As a preferred scheme, the frame body 1 is provided with a self-locking universal wheel 15 at the bottom. Through the setting of the self-locking universal wheel 15, the mobility of the whole placing frame is improved, and the movement is facilitated.

[0033] The utility model is introduced in detail above. The description of the specific embodiment is only used to help understand the method and the core idea of the utility model. It should be pointed out that for ordinary skilled persons in the technical field, the utility model can be improved and modified on the premise of not departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claim.
