Description

Technical Field

[0001] The invention belongs to the technical field of safety barrier bars, and in particular relates to a sophisticated barrier bar for realizing emergency stop safety. Background Art

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

[0003] Traditional sensor detection methods often involve complex signal processing processes, which often result in long response times and cannot meet the needs of rapid response, especially in emergency situations; some existing emergency stop devices are not designed with full consideration of the requirements for easy maintenance, which makes repair and replacement of parts complicated and costly in the event of a failure; 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] In view of the above problems, the present invention provides a new emergency stop safety lever solution, which solves the above problems by optimizing the combination of mechanical structure and electronic components. Summary of the invention

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a sophisticated emergency stop safety barrier rod, comprising a circuit tube and sleeves correspondingly arranged at both ends of the circuit tube; the circuit tube comprises a tube body, an annular tube threadedly mounted on both ends of the tube body, and a push switch mounted inside the annular tube; the sleeve comprises an outer tube threadedly connected to the outer end of the annular tube, a limit end cover threadedly connected to the end of the outer tube, a nylon rod movably arranged at the center of the limit end cover, a balance ring fixed on the circumference of the nylon rod, a positioning ring fixed on the inner wall of the outer tube, and a spring sleeved on the outside of the nylon rod; the inner end of the nylon rod cooperates with the push switch.

[0007] The present invention is further configured such that a saddle seat is symmetrically fixed to the circumferential side of the cylinder, and the saddle seat is fixed to the outer mounting surface via a fastener.

[0008] The present invention is further configured such that a threading hole is opened on the circumferential side of the cylinder, the connecting wire of the push switch is passed through the threading hole, and a gasket for sealing and protecting the connecting wire is built into the threading hole.

[0009] The present invention is further configured such that the push switch includes a shell, a threaded connection portion integrally arranged on the circumference of the shell, a connecting seat located at the rear of the shell, a metal connecting end connected to the internal components of the connecting seat, and a button elastically embedded in the front of the shell.

[0010] The present invention is further configured such that the outer end of the nylon rod is provided with a protective sleeve, the inner end of the nylon rod is integrally provided with an annular protrusion, and the circumference of the annular protrusion is in contact with the inner wall of the outer tube.

[0011] The present invention is further configured such that a circular opening for the nylon rod to pass through is provided in the middle of the positioning ring, the spring is located between the positioning ring and the balancing ring, and the outer side of the balancing ring is in contact with the inner wall of the outer tube.

[0012] The present invention is further configured such that the two push switches are connected in parallel.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention combines mechanical structure with electronic components. The emergency stop safety lever can quickly trigger the emergency stop function when external force is detected, effectively improving the safety of the operating environment of industrial automation equipment. A push switch is used instead of the traditional sensor detection method. This direct electrical signal transmission method is faster and more reliable than the traditional detection method, reducing the response time of the system, so that it can respond more quickly in an emergency and ensure the safety of personnel and equipment.

[0015] 2. The present invention assists in maintaining the verticality of the nylon rod by providing structures such as a balancing ring, a positioning ring, and a spring, ensuring that there will be no tilting or jamming during the pressing process, thereby improving the accuracy and stability of the operation. The travel range of the balancing ring limited by the limit end cover and the positioning ring also provides a guiding effect for the nylon rod, and the spring provides the necessary restoring force for resetting the nylon rod.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] See also Figure 1-4 The present invention is a sophisticated emergency stop safety barrier rod, comprising a circuit barrel 100 and sleeves 200 correspondingly arranged at both ends of the circuit barrel 100; the circuit barrel 100 comprises a barrel body 101, an annular barrel 102 threadedly mounted at both ends of the barrel body 101, and a push switch 103 mounted inside the annular barrel 102. The barrel body 101 serves as the basic supporting structure of the entire emergency stop safety barrier rod. The barrel body 101 not only provides necessary physical protection, but also ensures the stability and safety of internal components. The annular barrel 102 is fixed at both ends of the barrel body 101 by threading, which not only simplifies the assembly process, but also enhances the sealing performance, preventing external factors such as dust and moisture from damaging internal electronic components.

[0027] The sleeve 200 includes an outer cylinder 201 threadedly connected to the outer end of the annular cylinder 102, a limit end cover 202 threadedly connected to the end of the outer cylinder 201, a nylon rod 203 movably inserted into the center of the limit end cover 202, a balance ring 205 fixed to the circumference 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 press switch 103, and the balance ring 205 assists in maintaining the verticality of the rod body to ensure that there will be no tilting or jamming during the pressing process, thereby improving the accuracy and stability of the operation; the travel range of the balance ring 205 limited by the limit end cover 202 and the positioning ring 206 also provides a guiding effect for the nylon rod 203.

[0028] Specifically, the push switch 103 includes a housing 103b, a threaded connection portion 103e integrally arranged on the periphery of the housing 103b, a connection base 103c located at the rear of the housing 103b, a metal connection terminal 103d connected to the internal components of the connection base 103c, and a button 103a elastically embedded in the front of the housing 103b. The push switch 103 is used to replace the current sensor detection, which is more durable and can reduce the cost of equipment. The housing 103b is made of high-strength material to resist external impact and protect Internal mechanical structure: The threaded connection part 103e enables the push switch 103 to be firmly installed in the annular tube 102 to avoid loosening due to vibration or accidental collision. The connection seat 103c and the metal connection 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, and reduces the response time. The button 103a is elastically embedded in the front part 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 sleeved with a protective sleeve 204, and the inner end of the nylon rod 203 is integrally provided with an annular protrusion 203a, and the circumference of the annular protrusion 203a is in contact with the inner wall of the outer cylinder 201. The middle part of the positioning ring 206 is provided with a circular opening for the nylon rod 203 to pass through, and the inner diameter of the circular opening is smaller than the outer diameter of the annular protrusion 203a, so as to prevent the nylon rod 203 from being separated from the outer cylinder 201 during the movement. The spring 207 is located between the positioning ring 206 and the balance ring 205, and the outer side of the balance ring 205 is in contact with the inner wall of the outer cylinder 201. The spring 207 provides the necessary restoring force. When the nylon rod 203 loses the external thrust, the spring 207 recovers its deformation, and restores the nylon rod 203 to its original position, so that the ring at its inner end The annular protrusion 203a is disengaged from the push switch 103. Conversely, when the nylon rod 203 is subjected to external thrust, the nylon rod 203 contracts toward the inside of the outer tube 201. During this process, the balance ring 205 fixed to the nylon rod 203 moves synchronously until the annular protrusion 203a at the inner end of the nylon rod 203 is separated from the push switch 103. During this process, the balance ring 205 pushes the spring 207 to compress, and the spring 207 can also produce motion buffering 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 tube 201 to ensure the stable linear movement of the nylon rod 203. The protective sleeve 204 sleeved on the end of the nylon rod 203 effectively realizes collision protection.

[0030] Furthermore, a saddle seat is symmetrically fixed on the circumference of the cylinder 101, and the saddle seat is fixed to the external mounting surface via fasteners. A threading hole is opened on the circumference of the cylinder 101, and the connecting wire of the push switch 103 is passed through the threading hole, and the threading hole has a gasket for sealing and protecting the connecting wire. The opening of the threading hole depends on actual usage requirements, but the two push switches 103 are connected in parallel.

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

[0032] In the absence of external force, the nylon rod 203 is in the initial position, the button 103a is not triggered, and the entire system remains in operation; when the nylon rod 203 is forced to move inward, it drives the balance ring 205 to move synchronously, compressing the spring 207, and 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 connecting end 103d and the connecting seat 103c. After the external force applied to the protective cover 204 is removed, due to the restoring force of the spring 207, the nylon rod 203 will return to its original position, the annular protrusion 203a will separate from the push switch 103, and the button 103a will pop out.
