[0002] With increasing environmental awareness and the promotion of relevant policies, most cement companies have switched from plastic bags to environmentally friendly paper bags for their cement packaging.

[0003] However, traditional unloading hooks for bagged cement typically use a sharp hook at the end for dragging. This design easily damages the paper bags when used with environmentally friendly paper bags, leading to cement leakage. This not only causes economic losses for customers but also affects unloading efficiency. Therefore, a new unloading hook for bagged cement is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the problem that traditional unloading hooks for bagged cement typically use a sharp hook at the end for dragging operations. This design is prone to causing damage to the paper bags when used with environmentally friendly paper bags, leading to cement leakage. This not only causes economic losses to customers but also affects unloading efficiency.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The present invention is as follows: a bagged cement unloading hook, comprising a long rod, a loading and unloading component at the bottom of the long rod, a length adjustment component on the long rod, and a buffer component on the length adjustment component;

[0007] The loading and unloading assembly includes a triangular hook welded to the bottom of a long rod. The triangular hook is an isosceles triangle with arc surfaces at its three corners. A sharp knife hook is welded to the bottom periphery of the long rod. The sharp knife hook is a right-angled triangle.

[0008] As a preferred technical solution of this utility model, the length adjustment component includes an extension rod slidably mounted on a long rod, a positioning inner ring fixedly mounted at the bottom of the extension rod, a positioning ring tooth provided at the bottom of the positioning inner ring, a plurality of tightening grooves provided on the positioning ring tooth, the positioning ring tooth tightly fitting with the long rod, a positioning outer ring threadedly mounted on the positioning inner ring, and a positioning compression ring provided at the bottom of the positioning outer ring, the positioning compression ring being used to compress the positioning ring tooth.

[0009] As a preferred technical solution of this utility model, the buffer assembly includes a buffer chamber opened at the top of the extension rod, and multiple rubber pads are adhered to the inner wall of the buffer chamber. Two rubber pads form a group, and a buffer spring is installed between each group of rubber pads.

[0010] As a preferred technical solution of this utility model, a first friction rubber ring is fixedly provided on one side of the positioning inner ring, and a second friction rubber ring is fixedly provided on the side of the positioning outer ring close to the first friction rubber ring.

[0011] As a preferred technical solution of this utility model, a handle is welded to the top of the extension rod, and the handle is made of stainless steel.

[0012] As a preferred technical solution of this utility model, an anti-slip sleeve is fitted around the top of the extension rod, and an anti-slip groove is provided on the anti-slip sleeve. The anti-slip sleeve is made of rubber.

[0013] As a preferred technical solution of this utility model, the long rod, the triangular hook body, the sharp knife hook body and the extension rod are all made of stainless steel.

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

[0015] 1. By setting up loading and unloading components, when loading and unloading bagged cement, the triangular hook is welded to the bottom of the long pole. Its isosceles triangle shape and the arc design at the three corners make it easy to hook the bagged cement during loading and unloading, which is less likely to cause damage to the paper bag and will not cause losses to customers. The right-angled triangular knife hook welded to the bottom of the long pole faces the opposite direction to the triangular hook and can be used to cut open the packaging bag of cement to facilitate the pouring of cement. The triangular hook and the knife hook can not only easily hook the bagged cement to prevent the cement bag from breaking, but also quickly cut open the packaging bag to facilitate the pouring out of the cement in the bag, thus improving loading and unloading efficiency.

[0016] 2. By setting up a length adjustment component, when the length of the long rod needs to be adjusted, the overall length is changed by sliding the extension rod on the long rod. The positioning inner ring is fixed to the bottom of the extension rod, and the positioning ring teeth are tightly fitted with the long rod. Multiple tightening grooves on the positioning ring teeth give it a certain degree of elasticity. Rotating the positioning outer ring will cause the positioning compression ring at the bottom of the positioning outer ring to squeeze the positioning ring teeth, tightening them and thus fixing them tightly to the long rod, achieving length adjustment and fixation. The length adjustment component allows the unloading hook to flexibly adjust its length according to different usage scenarios and operator needs, improving the versatility and applicability of the unloading hook.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1 As shown, this embodiment proposes a bagged cement unloading hook, including a long rod 1, a loading and unloading component 2 at the bottom of the long rod 1, a length adjustment component 3 on the long rod 1, and a buffer component 4 on the length adjustment component 3.

[0028] like Figure 3As shown, the loading and unloading assembly 2 includes a triangular hook 201 welded to the bottom of a long rod 1. The triangular hook 201 is an isosceles triangle with arc surfaces 202 at its three corners. A sharp-blade hook 203 is welded to the bottom periphery of the long rod 1. The sharp-blade hook 203 is a right-angled triangle. When loading and unloading bagged cement, the triangular hook 201 is welded to the bottom of the long rod 1. Its isosceles triangle shape and the arc surfaces 202 at its three corners make it easy to hook the bagged cement during loading and unloading, preventing damage to the paper bag and avoiding losses to the customer. The right-angled triangular sharp-blade hook 203 welded to the bottom periphery of the long rod 1 faces the opposite direction to the triangular hook 201 and can be used to cut open the packaging bag of the bagged cement, facilitating the pouring of the cement. The triangular hook 201 and the sharp-blade hook 203 make it easy to hook the bagged cement during unloading to prevent the cement bag from breaking, and also quickly cut open the packaging bag to facilitate the pouring of the cement in the bag, improving loading and unloading efficiency.

[0029] like Figure 3 and Figure 5 As shown, the length adjustment assembly 3 includes an extension rod 301 slidably mounted on a long rod 1. A positioning inner ring 302 is fixedly mounted on the bottom of the extension rod 301. A positioning ring tooth 303 is provided at the bottom of the positioning inner ring 302. Multiple tightening grooves 304 are provided on the positioning ring tooth 303. The positioning ring tooth 303 is tightly fitted with the long rod 1. A positioning outer ring 305 is threaded onto the positioning inner ring 302. A positioning compression ring 306 is provided at the bottom of the positioning outer ring 305. The positioning compression ring 306 is used to compress the positioning ring tooth 303. When the length of the long rod 1 needs to be adjusted, the overall length is changed by sliding the extension rod 301 on the long rod 1. The positioning inner ring 302 is fixed to the bottom of the extension rod 301, and the positioning ring tooth 303 is tightly fitted with the long rod 1. The multiple tightening grooves 304 on the positioning ring tooth 303 give it a certain elasticity. When the positioning outer ring 305 is rotated, the positioning compression ring 306 at the bottom of the positioning outer ring 305 will squeeze the positioning ring tooth 303, making the positioning ring tooth 303 tighten, thereby fixing it tightly to the long rod 1, realizing the adjustment and fixation of the length.

[0030] like Figure 4 As shown, the buffer assembly 4 includes a buffer chamber 401 opened at the top of the extension rod 301. Multiple rubber pads 402 are adhered to the inner wall of the buffer chamber 401, with two rubber pads 402 forming a group. A buffer spring 403 is installed between each group of rubber pads 402. During the use of the unloading hook, when subjected to external impact or excessive force by the operator, the buffer assembly 4 inside the buffer chamber 401 at the top of the extension rod 301 functions. The multiple rubber pads 402 adhered to the inner wall of the buffer chamber 401, and the buffer springs 403 installed between each group of rubber pads 402, can absorb and disperse external forces, reducing the impact on the unloading hook and the operator, lowering the vibration and impact experienced by the operator during operation, and improving operational safety and comfort.

[0031] like Figure 5 As shown, a first friction rubber ring 5 is fixedly installed on one side of the positioning inner ring 302, and a second friction rubber ring 6 is fixedly installed on the side of the positioning outer ring 305 near the first friction rubber ring 5. During use, when the positioning outer ring 305 rotates for length adjustment and fixation, the first friction rubber ring 5 on one side of the positioning inner ring 302 and the second friction rubber ring 6 on the side of the positioning outer ring 305 near the first friction rubber ring 5 come into contact with each other. These two sets of friction rubber rings increase the friction between the positioning inner ring 302 and the positioning outer ring 305, making the positioning more secure and preventing the positioning outer ring 305 from loosening during use. This improves the fixing effect of the length adjustment component 3 and ensures that the unloading hook can be used stably after length adjustment, without affecting operation due to loosening.

[0032] like Figure 4 As shown, a handle 7 is welded to the top of the extension rod 301. The handle 7 is made of stainless steel, and provides a gripping point for the operator during use. The stainless steel handle 7 has sufficient strength and durability to withstand the force applied by the operator, making it convenient for the operator to operate the unloading hook.

[0033] like Figure 4 As shown, an anti-slip sleeve 8 is fitted around the top of the extension rod 301. The anti-slip sleeve 8 has an anti-slip groove 9. The anti-slip sleeve 8 is made of rubber. When the operator holds the anti-slip sleeve 8, the rubber material and the anti-slip groove 9 can increase the friction between the hand and the anti-slip sleeve 8, prevent the hand from slipping, and ensure that the operator can hold the unloading hook stably.

[0034] like Figure 3 As shown, the long rod 1, triangular hook body 201, sharp hook body 203, and extension rod 301 are all made of stainless steel. During use, the long rod 1, triangular hook body 201, sharp hook body 203, and extension rod 301 are all made of stainless steel. Stainless steel has excellent corrosion resistance, strength, and durability, ensuring that the unloading hook can work normally in various harsh environments and is not easily rusted or damaged.

[0035] Specifically, when using this bagged cement unloading hook: During loading and unloading of bagged cement, the triangular hook 201 is welded to the bottom of the long rod 1. Its isosceles triangle shape and the arc surface 202 at the three corners facilitate hooking the bagged cement during loading and unloading, preventing damage to the paper bag and avoiding losses for the customer. The right-angled triangular knife hook 203 welded to the bottom of the long rod 1 faces opposite to the triangular hook 201 and can be used to cut open the bagged cement packaging bag, facilitating the pouring of cement. The triangular hook 201 and the knife hook 203 allow for convenient hooking of the bagged cement during unloading to prevent breakage, and also allow for quick cutting of the packaging bag to facilitate the pouring of cement, improving loading and unloading efficiency (e.g., ...). Figure 3 and Figure 5 As shown), when the length of the long rod 1 needs to be adjusted, the overall length is changed by sliding the extension rod 301 on the long rod 1. The positioning inner ring 302 is fixed to the bottom of the extension rod 301, and the positioning ring tooth 303 is tightly fitted with the long rod 1. The multiple tightening grooves 304 on the positioning ring tooth 303 give it a certain elasticity. Rotating the positioning outer ring 305 will cause the positioning compression ring 306 at the bottom of the positioning outer ring 305 to compress the positioning ring tooth 303, tightening the positioning ring tooth 303 and thus fixing it tightly to the long rod 1, realizing the adjustment and fixation of the length. The length adjustment component 3 allows the unloading hook to flexibly adjust its length according to different usage scenarios and operator needs, improving the versatility and applicability of the unloading hook (such as...). Figure 3 and Figure 5 (As shown).
