Description

A dustproof sealing assembly for a pneumatic vibrator Technical Field

[0001] This utility model relates to the field of pneumatic vibrator technology, and in particular to a dustproof sealing component for a pneumatic vibrator. Background Technology

[0002] A pneumatic vibrator is a device that generates mechanical vibration by being driven by compressed air. It is widely used in industrial production where material accumulation needs to be eliminated, flow promoted, or screening assisted. The sealing components of a pneumatic vibrator are crucial for ensuring its normal operation and preventing gas leakage. The rubber coupling sleeve connecting the hose is an important part of the sealing system. In existing technology, if the rubber coupling sleeve and hose of a pneumatic vibrator are subjected to high-frequency vibration for a long time, the rubber will age, the clamps will lose elasticity, and the internal seals of the joint will deform due to air pressure exceeding the rated value, all of which can easily lead to sudden detachment. Once detached, the high-pressure airflow will be ejected instantaneously, pushing the hose and striking personnel, thus causing a safety accident. Summary of the Invention

[0003] The purpose of this invention is to address the problems in the prior art, such as aging of the rubber connecting sleeve and failure of the claws in pneumatic vibrators caused by high-frequency vibration, deformation and detachment of the seals due to overpressure, and injury caused by high-pressure airflow pushing the hose. This invention proposes a dustproof sealing component for pneumatic vibrators.

[0004] The technical solution of this utility model is as follows: A dustproof sealing assembly for a pneumatic vibrator includes a pneumatic vibrator body and a connecting sleeve disposed on the upper surface of one end of the pneumatic vibrator body. A connecting hose is movably inserted into the top of the connecting sleeve. The assembly also includes: a rubber ferrule fixedly sleeved on the connecting sleeve, with a limiting band fixedly connected to the outer wall of the rubber ferrule; a ferrule mechanism disposed on one end of the limiting band that tightly clamps the end of the connecting hose, the ferrule mechanism including a first ferrule and a second ferrule; and a locking mechanism disposed on the ferrule mechanism to enable a quick-release connection between the first ferrule and the second ferrule and the connecting hose.

[0005] Optionally, the locking mechanism includes a second connector and a third connector fixedly connected to the ends of the first and second sleeves. A fixing screw is movably provided on the third connector, and a locking nut that is spirally connected to the fixing screw is embedded on the second connector.

[0006] Optionally, a knob is fixedly connected to the end of the fixing screw away from the locking nut.

[0007] Optionally, the knob may have multiple anti-slip grooves arranged in a circumferential array.

[0008] Optionally, the first connector is fixedly connected to the end of the first sleeve away from the second connector, and the fourth connector is fixedly connected to the end of the second sleeve away from the third connector. A rotating groove is provided on the first connector for the fourth connector to rotate.

[0009] Optionally, the rubber ferrule has a locking groove inside to lock the connecting sleeve.

[0010] Optionally, the limiting band is made of polyhexamethylene adipamide.

[0011] Optionally, a silencer is movably connected to the upper surface of the pneumatic vibrator body at the end away from the connecting sleeve.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model utilizes a combination of a rubber ferrule, a ferrule mechanism, and a locking mechanism to create a dustproof sealing component for pneumatic vibrators. When the connecting hose detaches from the connecting sleeve, it is held in place by a limiting band, preventing it from completely falling off. This design, with the help of the limiting band, prevents high-pressure airflow from being ejected and striking personnel even if the rubber ages, the clamps fail, or the seals deform, thus ensuring personnel safety.

[0025] Example

[0026] As shown in Figures 1 to 4, the dustproof sealing assembly for a pneumatic vibrator proposed in this utility model includes a pneumatic vibrator body 1 and a connecting sleeve 11 disposed on the upper surface of one end of the pneumatic vibrator body 1. A silencer 6 is movably connected to the upper surface of the end of the pneumatic vibrator body 1 away from the connecting sleeve 11. The main function of the silencer 6 is to reduce the noise generated during equipment operation and reduce the impact on the working environment and operators. A connecting hose 2 is movably inserted into the top of the connecting sleeve 11, and the connecting hose 2 is movably inserted into the top of the connecting sleeve 11 to transmit compressed air to the pneumatic vibrator body 1. A rubber clamp 3 is fixedly fitted on the connecting sleeve 11. The rubber clamp 3 is clamped to the connecting sleeve 11 through an internal locking groove 31, and a limiting band 32 is connected to the outer wall. The limiting band 32 is fixedly connected to the outer wall of the rubber clamp 3 to limit the uncontrolled connecting hose 2. The limiting band 32 is made of polyhexamethylene adipamide. Polyhexamethylene adipamide has high strength and fatigue resistance, which can resist the influence of high frequency vibration of pneumatic vibrator and prevent the limiting band from breaking due to vibration. One end of the limiting band 32 is provided with a clamping mechanism that tightly clamps the end of the connecting hose 2. The clamping mechanism includes a first clamping sleeve 4 and a second clamping sleeve 5.

[0027] As shown in Figures 1, 3, and 4, the ferrule mechanism includes a locking mechanism that allows for quick-release connection between the first ferrule 4 and the second ferrule 5 and the connecting hose 2. The locking mechanism includes a second connector 42 and a third connector 51 fixedly connected to the ends of the first ferrule 4 and the second ferrule 5. A fixing screw 53 is movably mounted on the third connector 51, and the fixing screw 53 is screwed into a locking nut 43. Tightening the screw causes the first ferrule 4 and the second ferrule 5 to clamp the connecting hose 2. A locking nut 43, screwed into the second connector 42, is also screwed into the second connector 42, locking the first ferrule 4 and the second ferrule 5. A knob 54 is fixedly connected to the end of the fixing screw 53 furthest from the locking nut 43, facilitating the turning of the fixing screw 53. The knob 54 has multiple anti-slip grooves arranged in a circumferential array. The anti-slip grooves increase the friction of the contact surface, making it easier for the operator to turn the knob 54 and less prone to slipping. This allows the fixing screw 53 to rotate more smoothly, enabling the first ferrule 4 and the second ferrule 5 to fasten or disassemble the connecting hose 2, thus improving ease of use and operational stability.

[0028] Additionally, as shown in Figures 3 and 4, the first connector 41 is fixedly connected to the end of the first ferrule 4 away from the second connector 42, and the fourth connector 52 is fixedly connected to the end of the second ferrule 5 away from the third connector 51. A rotating groove 44 is provided on the first connector 41 for the fourth connector 52 to rotate. The rotating groove 44 allows the fourth connector 52 to rotate, so that the first ferrule 4 and the second ferrule 5 can be opened and closed.

[0029] It is worth noting that, as shown in Figure 3, the rubber sleeve 3 has a locking groove 31 inside to lock the connecting sleeve 11. The locking groove 31 locks the connecting sleeve 11 and fixes the position of the rubber sleeve 3.

[0030] In this embodiment, when using the dustproof sealing assembly of the pneumatic vibrator, the connecting hose 2 is inserted into the connecting sleeve 11, and then the rubber clamp 3 is fitted onto the connecting sleeve 11 through the locking groove 31. Next, the first clamp 4 and the second clamp 5 grip the end of the connecting hose 2, and then the fourth connector 52 rotates within the rotating groove 44, aligning the second connector 42 and the third connector 51. Then, the knob 54 is turned to rotate the fixing screw 53. Since the fixing screw 53 is screwed to the locking nut 43, the first clamp 4 and the second clamp 5 tightly grip the connecting hose 2. This also allows for a quick-release connection between the connecting hose 2 and the first clamp 4 and the second clamp 5, thus preventing high-pressure airflow from pushing the connecting hose 2 and hitting the worker if the connecting hose 2 detaches.

[0031] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
