Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a push-pull emergency stop button. Background Technology

[0002] An emergency stop switch is a type of master control electrical appliance. When a machine is in a dangerous state, the power supply is cut off by the emergency stop switch to stop the equipment and protect the safety of personnel and equipment. Emergency stop switches are usually manually controlled push-button switches that are connected in series with the control circuit of the equipment. They are used to directly disconnect the power supply to the control circuit in an emergency to quickly stop the equipment and avoid abnormal operation. They are one of the important components in various common electrical equipment.

[0003] Existing emergency stop buttons have the following drawbacks: Common emergency stop buttons typically use an internal cam and support rod to drive a bridge-type moving contact structure. Long-term friction can cause wear and deformation of the cam surface or the hinge point of the connecting rod, reducing power transmission efficiency and potentially leading to incomplete contact separation or response time delay. Furthermore, the cam positioning accuracy is easily affected by equipment vibration, which may cause malfunctions. Therefore, we propose a push-pull emergency stop button. Utility Model Content

[0004] The main purpose of this utility model is to provide a push-pull emergency stop button. By improving the internal structure of the emergency stop switch and adopting a spring-loaded self-locking structure, it can quickly trigger the emergency stop. At the same time, it can be reset by simply pulling it outward, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A push-pull emergency stop button includes an emergency stop button body and a cap. The emergency stop button body has a slot at its center and a rod inserted into the slot at the bottom of the cap. Grooves are symmetrically formed on both sides of the bottom of the slot. A horizontal groove is formed inside the rod. Steel balls are inserted into both ends of the horizontal groove, and a thrust spring is inserted between the steel balls. A micro switch is provided inside the emergency stop button body at the bottom of the rod.

[0007] Furthermore, a main spring is installed at the top of the emergency stop button body and connected to the bottom of the cap through the main spring; the main spring acts as a connection between the emergency stop button body and the cap and can apply a reset force to the cap.

[0008] Furthermore, a housing rib is integrally formed on one side of the inner wall of the emergency stop button body, and an anti-rotation plate is installed at the bottom end of the insertion rod, with a slot on the side of the anti-rotation plate. The slot corresponds to the position of the housing rib, and the housing rib is inserted into the slot. The housing rib and the slot structure on the side of the anti-rotation plate cooperate to prevent the cap structure from rotating and allow it to move only along the axis of the emergency stop button body.

[0009] Furthermore, an O-ring A is embedded inside the emergency stop button body near the cap, and an O-ring B is embedded at the bottom of the emergency stop button body; the O-ring A plays a sealing role at the connection between the cap and the emergency stop button body, and the O-ring B plays a sealing role at the bottom of the emergency stop button body.

[0010] Furthermore, a cable inlet tube is detachably connected to the side of the emergency stop button body, and a cable sealing ring is sleeved at the connection between the inside of the cable inlet tube and the emergency stop button body; the inside of the cable inlet tube is used to insert a cable, connect the micro switch and the machine circuit, so that the emergency stop button body can control the machine, and the cable sealing ring at the connection can play a sealing role at the connection.

[0011] Compared with the prior art, this utility model has the following advantages: A slot is provided inside the main body of the emergency stop button, and a cap structure is provided at the top of the slot. The insert rod is inserted into the slot and, in the normal state, is away from the groove. In the untriggered state, the steel ball is confined within the horizontal groove by the inner wall of the slot, the thrust spring is compressed, and the micro switch is in the normal circuit-connected state. When an emergency stop is required, tapping the cap causes the insert rod to move. When the horizontal groove aligns with the groove, the steel ball is locked into the groove under the action of the thrust spring, and the micro switch is simultaneously activated to disconnect the circuit, completing the stop operation. The groove limits the steel ball, maintaining the power-off state. When a reset is required, pulling the cap in the opposite direction compresses the steel ball, compressing the thrust spring, and the steel ball is retracted into the horizontal groove. Pulling the cap then moves the micro switch, resetting the circuit and restoring it. The spring-controlled self-locking structure allows for quick circuit disconnection and maintenance of the disconnected state. Reset is achieved by pulling in the opposite direction. The structure is simple and the effect is stable. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-6 As shown, a push-pull emergency stop button includes an emergency stop button body 1 and a cap 2. The emergency stop button body 1 has a slot 5 at its center, and the cap 2 has a rod 201 inserted into the slot 5 at its bottom. Grooves 501 are symmetrically formed on both sides of the bottom of the inner wall of the slot 5. A horizontal groove 202 is formed in the horizontal direction inside the rod 201. Steel balls 204 are inserted into both ends of the horizontal groove 202, and a thrust spring 203 is inserted between the steel balls 204 inside the horizontal groove 202. A micro switch 6 is provided inside the emergency stop button body 1 at the bottom of the rod 201.

[0021] The emergency stop button body 1 has a main spring 4 installed at its top and connected to the bottom of the cap 2. A housing rib 101 is integrally formed on one side of the inner wall of the emergency stop button body 1. An anti-rotation plate 9 is installed at the bottom of the insertion rod 201 and a slot 901 is opened on the side of the anti-rotation plate 9. The slot 901 corresponds to the housing rib 101 and the housing rib 101 is inserted into the slot 901. The main spring 4 plays a connecting role between the emergency stop button body 1 and the cap 2 and can apply a reset force to the cap 2. The housing rib 101 and the slot 901 on the side of the anti-rotation plate 9 cooperate to prevent the cap 2 from rotating and can only move along the axis of the emergency stop button body 1.

[0022] The emergency stop button body 1 has an O-ring A205 embedded inside near the cap 2, and an O-ring B7 embedded at the bottom. A cable inlet pipe 3 is detachably connected to the side of the emergency stop button body 1, and a cable sealing ring 8 is fitted at the connection between the cable inlet pipe 3 and the emergency stop button body 1. The O-ring A205 seals the connection between the cap 2 and the emergency stop button body 1, and the O-ring B7 seals the bottom of the emergency stop button body 1.
