[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] The following describes various non-limiting embodiments of this utility model. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Example 1

[0026] like Figure 1 As shown, the anti-detachment device for the pressurized inlet pipeline of powdered materials includes an anti-detachment mechanism installed on the inlet pipeline 1. This anti-detachment mechanism is used to connect to the locking mechanism 3. The anti-detachment mechanism pulls the locking mechanism 3, causing the locking mechanism 3 to tilt, thereby increasing the holding force of the locking mechanism 3 on the tubular hose 2. In this way, the locking mechanism 3 can secure the tubular hose 2 to the inlet pipeline 1. By adding an anti-detachment mechanism to the inlet pipeline 1, the anti-detachment mechanism pulls the locking mechanism 3, causing the locking mechanism 3 to tilt, increasing the holding force of the locking mechanism 3 on the tubular hose 2, making the tubular hose 2 more stably installed on the inlet pipeline 1, and reducing the risk of the tubular hose 2 falling off.

[0027] The anti-detachment mechanism includes a linear moving part installed on the inlet pipe 1 and a connecting part connected to the moving end of the linear moving part. The linear moving part moves linearly, causing the connecting part to move. The connecting part is connected to the locking mechanism 3. The movement of the linear moving part causes the locking mechanism 3 to fasten the tubular hose 2 to the inlet pipe 1. The linear moving part can generate a tension force, causing the connecting part to tighten the locking mechanism 3. The locking mechanism 3 tilts, thereby allowing the locking mechanism 3 to exert a stronger holding force on the tubular hose 2, preventing the tubular hose 2 from easily detaching.

[0028] In this embodiment, as Figure 1 , Figure 2As shown, the linear moving component includes a sleeve 4 fixed to the inlet pipe 1. A screw 5 passes through the sleeve 4, meaning the sleeve 4 is fitted over the outside of the screw 5. One end of the screw 5 is connected to a connector, and the other end is threadedly connected to a nut 6. The nut 6 rotates to press against the sleeve 4, thereby driving the screw 5 to move linearly within the sleeve 4, which in turn causes the connector to tighten the locking mechanism 3. To prevent the screw 5 from rotating, pliers (wire cutters) can be used to fix the screw 5.

[0029] In this embodiment, the connector includes a chain 7, one end of which is connected to the screw 5, and the other end of which is provided with a hook. The chain 7 is wound around the locking mechanism 3, and the hook is engaged with the chain 7, so that when the chain 7 pulls the locking mechanism 3, the chain 7 will not fall off the locking mechanism 3, thus enabling the screw 5 to tighten the locking mechanism 3 when it moves.

[0030] In this embodiment, a nut 8 for wrench gripping is fixed to the end of the screw 5 away from the locking mechanism 3. When tightening the locking mechanism 3, one wrench turns the nut 6, while the other wrench can hold the nut 8 to prevent the screw 5 from rotating during the turning of the nut 6.

[0031] In this embodiment, as Figure 2 As shown, a stop ring 9 is provided on the end of the sleeve 4 away from the locking mechanism 3. The stop ring 9 is used to press against the nut 6 to stop it.

[0032] The working process of this utility model is as follows:

[0033] When using the anti-detachment device described in this embodiment, the tubular hose 2 has already been secured to the inlet pipe 1 using the locking mechanism 3. At this time, the chain 7 is wrapped around the locking mechanism 3, and hooked around the hook of the locking mechanism 3 to ensure that the chain 7 will not fall off the locking mechanism 3 when the chain 7 is tightened.

[0034] Then, one wrench tightens the nut 6, while the other wrench holds the nut 8, causing the screw 5 to move away from the locking mechanism 3, thereby tightening the locking mechanism 3 and tilting it. This allows the locking mechanism 3 to exert a stronger holding force on the tubular hose 2, reducing the risk of the tubular hose 2 falling off.

[0035] Example 2

[0036] The difference between the present embodiment and embodiment 1 is that the anti-falling mechanism in embodiment 1 is only one, while the anti-falling mechanism in the present embodiment has multiple, multiple anti-falling mechanisms are arranged circumferentially on the warehouse inlet pipeline 1, and the arrangement position is irregular, so that when multiple anti-falling mechanisms simultaneously pull the locking mechanism 3, the anti-falling mechanism can be tilted, reducing the risk of the tubular hose 2 falling off. Multiple anti-falling mechanisms simultaneously pull the locking mechanism 3, so that the locking mechanism 3 generates a stronger holding force on the tubular hose 2, reducing the risk of the tubular hose 2 falling off.

[0037] Embodiment 3

[0038] The difference between the present embodiment and embodiment 1 is that the linear moving part in embodiment 1 is the structure of sleeve 4, screw rod 5 and nut 6, while the linear moving part in the present embodiment is a gas cylinder, the telescopic end of the gas cylinder is connected with chain 7, thereby pulling the locking mechanism 3.

[0039] The gas cylinder can also be equivalent to an electric push rod or a hydraulic cylinder.

[0040] Embodiment 4

[0041] The difference between the present embodiment and embodiment 1 is that the anti-falling mechanism in embodiment 1 is a linear moving part and a connecting piece connected with the moving end of the linear moving part, while the anti-falling mechanism in the present embodiment is a tightener, such as Figure 3 As shown, the tightener has a main body 10, the opposite ends of the main body 10 are simultaneously threadedly connected with a first threaded rod 11 and a second threaded rod 12, wherein the first threaded rod 11 is connected with the warehouse inlet pipeline 1, and the second threaded rod 12 is connected with the locking mechanism 3. In use, the main body 10 is rotated to reduce the distance between the first threaded rod 11 and the second threaded rod 12, thereby pulling the locking mechanism 3.

[0042] The connection of the first threaded rod 11 with the warehouse inlet pipeline 1 and the connection of the second threaded rod 12 with the locking mechanism 3 in the present embodiment can be welding or hinging.

[0043] Embodiment 5

[0044] The difference between the present embodiment and embodiment 1 is that the connecting piece in embodiment 1 is chain 7, while the connecting piece in the present embodiment is a rod, which is fixedly connected or hinged with the locking mechanism 3.
