Description

Technical Field

[0001] This utility model relates to the field of lead seal installation technology, specifically a lead seal quick riveting mechanism. Background Technology

[0002] Plastic lead seals are disposable seals used to prevent unauthorized opening and are widely used in logistics, power, water, and metering equipment. The "riveting" of plastic lead seals is the core process for achieving a secure seal. Its purpose is to irreversibly connect the seal body to the sealing line (or lock core assembly) through plastic deformation, ensuring that it cannot be reused once sealed.

[0003] Existing lead seal riveting equipment typically needs to consider comprehensive conditions such as positioning, pressure control, and ambient temperature, resulting in complex equipment structure, inconvenient operation, additional maintenance costs, and indirectly affecting production efficiency.

[0004] Based on the above reasons, this utility model designs a rapid riveting mechanism for lead seals. By combining wedge guidance, elastic energy storage and impact transmission, it achieves rapid, efficient and stable riveting of plastic lead seals, greatly improving the efficiency and quality of the lead seal process. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid riveting mechanism for lead seals. By combining wedge guidance, elastic energy storage and impact transmission, it achieves rapid, efficient and stable riveting of plastic lead seals, greatly improving the efficiency and quality of the lead seal process.

[0006] To achieve the above objectives, this utility model provides a quick-connect riveting mechanism for lead seals. A flat-headed set screw is installed inside an adjusting sleeve on one side of the mechanism. The flat-headed set screw is connected to one end of a rear spring via a gasket located in the cavity inside the adjusting sleeve. The other end of the rear spring is connected to an impact block also located in the cavity inside the adjusting sleeve. One end of the adjusting sleeve is threadedly connected to a connector. The inner end face of the connector is a wedge-shaped surface that contacts the larger end of a tapered spring. The smaller end of the tapered spring is connected to the mounting handle of a lifting impact shaft. The inner end of the connector is threadedly connected to the lifting sleeve. A lifting impact shaft is located within the cavity of the connector and the lifting sleeve. One end of the lifting sleeve is threadedly connected to a limiting sleeve. A lead seal clamp is located inside the limiting sleeve. A slider rod is located inside the lead seal clamp. The inner end of the slider rod is connected to one end of the lifting impact shaft. The other end of the lifting impact shaft is inclinedly located at the junction of the impact block and the connector. The inner end of the lead seal clamp is connected to one end of a bottom spring, and the other end of the bottom spring is connected to one end of the lifting sleeve.

[0007] A lead seal is installed on the outer end of the lead seal clamp via a vertical slot.

[0008] The lead seal is installed with an interference fit to the vertical groove to a depth of 2mm.

[0009] The lifting impact shaft has a central protrusion, and one side of the protrusion is provided with an inclined surface to guide the lifting impact shaft from tilted to horizontal within the cavity of the connector.

[0010] The diameter of the outer end of the lifting impact shaft is smaller than the diameter of the cavity reserved inward on the impact block.

[0011] The diameter of the protrusion is the same as the inner diameter of the cavity in the connector.

[0012] The inner end of the slider rod is a limiting position that mates with the lifting sleeve.

[0013] The inner end of the lead seal clamp engages with the outer end of the limiting sleeve.

[0014] Compared with existing technologies, this invention utilizes the beveled surface of the inner end face of the connector to contact the larger surface of the tapered spring, thereby tilting the lifting impact shaft connected to the connector. This allows the rebound force of the rear spring to be stored. Furthermore, the beveled surface of the protruding side of the lifting impact shaft mates with the central cavity of the connector. During the movement of the lifting impact shaft, it transitions from tilting to horizontal, allowing it to enter the cavity on the impact block side and release the rebound force of the rear spring. This achieves precise riveting between the lead seal and the mounting hole. This invention, through pressing the mounting hole, achieves precise positioning of the installation position and provides pressure to the lifting impact shaft, causing it to transition from tilting to horizontal and triggering the impact, thus achieving rapid riveting. It is convenient to use, simple in structure, and greatly improves the efficiency and quality of the lead sealing process. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] See Figure 1This utility model provides a quick riveting mechanism for lead seals. A flat-headed set screw 12 is provided inside an adjusting sleeve 3 on one side of the mechanism. The flat-headed set screw 12 is connected to one end of a rear spring 14 via a gasket 6 located in the internal cavity of the adjusting sleeve 3. The other end of the rear spring 14 is connected to an impact block 4, also located in the internal cavity of the adjusting sleeve 3. One end of the adjusting sleeve 3 is threadedly connected to a connector 5. The inner end face of the connector 5 is a wedge-shaped surface 17 that contacts the larger end of a tapered spring 11. The smaller end of the tapered spring 11 is connected to the mounting handle 21 of the lifting impact shaft 2. The inner end of the connector 5 is threaded to the lifting sleeve 10. The inner cavity of the connector 5 and the lifting sleeve 10 is provided with a lifting impact shaft 2. One end of the lifting sleeve 10 is threaded to the limiting sleeve 9. The limiting sleeve 9 is provided with a lead seal clamp 7. The lead seal clamp 7 is provided with a slider rod 8. The inner end of the slider rod 8 is connected to one end of the lifting impact shaft 2. The other end of the lifting impact shaft 2 is inclined at the junction of the impact block 4 and the connector 5. The inner end of the lead seal clamp 7 is connected to one end of the bottom spring 13. The other end of the bottom spring 13 is connected to one end of the lifting sleeve 10.

[0020] A lead seal 1 is installed on the outer end of the lead seal clamp 7 through a vertical groove.

[0021] The lead seal 1 is installed with an interference fit to the vertical groove at a depth of 2mm.

[0022] The lifting impact shaft 2 has a central protrusion 18, and one side of the protrusion 18 is provided with an inclined surface 16 for guiding the lifting impact shaft 2 from an inclined position to a horizontal position within the cavity of the connector 5.

[0023] The diameter of the outer end of the lifting impact shaft 2 is smaller than the diameter of the cavity reserved inward by the impact block 4.

[0024] The diameter of protrusion 18 is the same as the inner diameter of the cavity 20 of connector 5.

[0025] The inner end of the slider rod 8 is a limit 19 that cooperates with the lifting sleeve 10.

[0026] The inner end of the lead seal clamp 7 engages with the outer end of the limiting sleeve 9.

[0027] Working principle:

[0028] See Figure 1This utility model requires minimal adjustment. First, the lead seal 1 is installed into the slot of the lead seal clamp 7. The lead seal clamp 7 is made of spring steel and has four vertical grooves, which provide a certain clamping force to prevent the lead seal 1 from falling off. Then, holding the device, the lead seal 1 is aligned with the mounting hole and pressed down. The lead seal clamp 7 and the slider rod 8 are forced to move upward, and the lifting impact shaft 2 also moves upward. The left end of the lifting impact shaft 2 hits the right end face of the impact block 4, causing the impact block 4 to also move upward. At this time, the rear spring 14 is compressed. After the lifting impact shaft 2 moves upward a certain distance, it is guided by the inclined surface 16 to the middle 20 of the cavity of the connector 5, guiding the left end of the lifting impact shaft 2 from one side to the center position. When the lifting shaft 2 moves to the center position, the contact with the right end face of the impact block 4 fails, and the middle hole of the impact block 4 will penetrate into the left end of the lifting shaft 2. The impact block 4 will quickly pop out, and the bottom surface of the inner hole will collide with the left end face of the lifting shaft 2. Through the lifting shaft 2, it acts on the slider rod 8, and the slider rod 8 impacts the lead seal 1, causing it to be installed into the mounting hole, completing one riveting process. When the device is lifted from the mounting hole position, since the pressure of the lead seal 1 on the lead seal clamp 7 disappears, under the rebound force of the bottom spring 13 connected to the lead seal clamp 7 and the lifting sleeve 10, the lead seal clamp 7 returns to the initial position. The lifting shaft 2 and the slider rod 8 will also return to the initial position. Under the action of the tapered spring 11 and the inclined wedge 17, that is, the tapered spring 11 gives an oblique elastic force due to the uneven force on the inclined wedge 17, causing the lifting shaft 2 to return to the tilted state again.

[0029] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0030] This invention comprehensively solves the shortcomings of existing lead seal riveting equipment, such as complex structure, inconvenient operation, additional maintenance costs, and indirect impact on production efficiency. By utilizing three sets of spring systems, combined with the tilting effect of the wedge surface and the tapered spring, each pressing action of the lead seal becomes a pre-trigger operation for riveting. This ensures accurate positioning of the riveting position and achieves an efficient and stable riveting rhythm, greatly improving the efficiency and quality of the lead seal process.
