Description

Technical Field

[0001] This utility model belongs to the field of safety stop bar technology, and in particular relates to a sophisticated emergency stop safety stop bar. Background Technology

[0002] In the field of industrial automation, emergency stop systems are essential to ensure operator safety and the normal operation of equipment. Traditional emergency stop devices mostly rely on sensor detection or mechanical triggering mechanisms to achieve emergency stop functionality. However, these methods have some limitations:

[0003] Traditional sensor detection methods often involve complex signal processing, resulting in long response times that cannot meet the needs of rapid response, especially in emergency situations. Some existing emergency stop devices are not designed with ease of maintenance in mind, making repair and replacement of parts complex and costly in the event of a malfunction. Previous designs lacked effective measures to ensure that there would be no tilting or jamming during the pressing process, which could lead to false triggering or untimely response.

[0004] To address the aforementioned problems, this utility model provides a new emergency stop safety lever solution, which solves the problems by optimizing the combination of mechanical structure and electronic components. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-4 This utility model is a sophisticated emergency stop safety lever, including a circuit cylinder 100 and sleeves 200 correspondingly disposed at both ends of the circuit cylinder 100; the circuit cylinder 100 includes a cylinder body 101, an annular cylinder 102 threadedly fitted to both ends of the cylinder body 101, and a push switch 103 fitted inside the annular cylinder 102. The cylinder body 101 serves as the basic support structure of the entire emergency stop safety lever. The cylinder body 101 not only provides necessary physical protection but also ensures the stability and safety of the internal components. The annular cylinder 102 is fixed to both ends of the cylinder body 101 by threads, which not only simplifies the assembly process but also enhances the sealing performance, preventing external factors such as dust and moisture from damaging the internal electronic components.

[0027] The sleeve 200 includes an outer cylinder 201 threaded to the outer end of the annular cylinder 102, a limiting end cap 202 threaded to the end of the outer cylinder 201, a nylon rod 203 movably passing through the center of the limiting end cap 202, a balance ring 205 fixed to the periphery of the nylon rod 203, a positioning ring 206 fixed to the inner wall of the outer cylinder 201, and a spring 207 sleeved on the outside of the nylon rod 203. The inner end of the nylon rod 203 cooperates with the push switch 103. The balance ring 205 helps to maintain the verticality of the rod, ensuring that there is no tilting or jamming during the pressing process, thus improving the accuracy and stability of the operation. The limit of the stroke range of the balance ring 205 by the limiting end cap 202 and the positioning ring 206 also provides a guiding function for the nylon rod 203.

[0028] Specifically, the push-button switch 103 includes a housing 103b, a threaded connection portion 103e integrally formed on the periphery of the housing 103b, a connecting seat 103c located at the tail of the housing 103b, a metal connecting end 103d connected to the internal components of the connecting seat 103c, and a button 103a elastically embedded in the front of the housing 103b. Using the push-button switch 103 instead of the current sensor detection method is more durable and reduces equipment costs. The housing 103b is made of high-strength material to withstand external impacts and protect the device. The internal mechanical structure and threaded connection 103e allow the push switch 103 to be securely installed inside the annular cylinder 102, preventing loosening due to vibration or accidental collision. The connecting seat 103c and the metal connecting end 103d are responsible for transmitting the push signal to the control system to realize the emergency stop function. This direct electrical signal transmission method is faster and more reliable than traditional sensor detection, reducing response time. The button 103a is elastically embedded in the front of the housing 103b, and the emergency stop is triggered by pressing the nylon rod 203.

[0029] The outer end of the nylon rod 203 is fitted with a protective sleeve 204. An annular protrusion 203a is integrally formed on the inner end of the nylon rod 203. The annular protrusion 203a is circumferentially fitted to the inner wall of the outer cylinder 201. A circular opening for the nylon rod 203 to pass through is formed in the center of the positioning ring 206. The inner diameter of the circular opening is smaller than the outer diameter of the annular protrusion 203a to prevent the nylon rod 203 from detaching from the outer cylinder 201 during movement. The spring 207 is located between the positioning ring 206 and the balance ring 205, with the outer side of the balance ring 205 fitting against the inner wall of the outer cylinder 201. The spring 207 provides the necessary restoring force. When the nylon rod 203 loses external thrust, the spring 207 recovers its deformation, restoring the nylon rod 203 to its original position, thereby restoring the inner end of the annular protrusion 203a. The protrusion 203a disengages from the push switch 103. Conversely, when the nylon rod 203 is subjected to external thrust, it retracts into the outer cylinder 201. During this process, the balance ring 205, which is fixed to the nylon rod 203, moves synchronously until the annular protrusion 203a at the inner end of the nylon rod 203 contacts the push switch 103. During this process, the balance ring 205 pushes the spring 207 to compress, and the spring 207 can also provide motion buffer for the nylon rod 203 to avoid excessive impact on the push switch 103. During the reciprocating movement of the nylon rod 203, the balance ring 205 contacts the inner wall of the outer cylinder 201 to ensure the stable linear movement of the nylon rod 203. The protective sleeve 204 fitted at the end of the nylon rod 203 effectively provides collision protection.

[0030] Furthermore, saddle seats are symmetrically fixed on the periphery of the cylinder 101, and the saddle seats are fixed to the outer mounting surface by fasteners to realize the installation and fixation of the stop bar. A wire hole is opened on the periphery of the cylinder 101, and the connecting wire of the push switch 103 passes through the wire hole. The wire hole is equipped with a gasket for sealing and protecting the connecting wire. The opening of the wire hole depends on the actual use requirements, but the two push switches 103 are connected in parallel.

[0031] The emergency stop safety lever proposed in this embodiment provides an emergency stop function in industrial automation equipment. By combining mechanical structure and electronic components, it achieves rapid response and high reliability, aiming to improve the safety of the working environment while reducing maintenance costs.

[0032] When no external force is applied, the nylon rod 203 is in its initial position, the button 103a is not triggered, and the entire system remains operational. When the nylon rod 203 is forced to move inward, it drives the balance ring 205 to move synchronously, compressing the spring 207. At the same time, the annular protrusion 203a gradually approaches and eventually touches the button 103a of the push switch 103. Once the button 103a is pressed, the electrical signal is immediately transmitted to the control system through the metal connection end 103d and the connecting seat 103c. After the external force applied to the protective sleeve 204 is removed, the nylon rod 203 returns to its original position due to the restoring force of the spring 207. The annular protrusion 203a separates from the push switch 103, and the button 103a pops out.
