[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1 and Figure 2 The shown emergency stop pulling fork structure includes a dial plate 1, a support plate 2 and a flat plate 3, the dial plate 1 and the support plate 2 are both L-shaped and arranged correspondingly on the left and right sides, a slot 21 is provided at the corner of the support plate 2, the lower end of the dial plate 1 is inserted into the slot 21, and the dial plate 1 can rotate relative to the corner of the support plate 2, the support plates 2 on both sides are connected by the flat plate 3, the two ends of the flat plate 3 are provided with folding plates 31 at the connection between the support plate 2, and the folding plates 31 are fixed to the support plate 2, and the flat plate 3 is passed through a rotating core 4, and the tail of the rotating core 4 is sequentially provided with a first signal turntable 41 and a second signal turntable 42, and the lower end of the dial plate 1 is inserted into the gap between the first signal turntable 41 and the second signal turntable 42, the upper end of the dial plate 1 is provided with a notch 11, a socket 5 passes through the notch 11, and the upper end of the dial plate 1 extends into the open groove on the socket 5, and the sockets 5 on both sides are connected by tension springs 51.

[0018] As a preferred embodiment, a spacer 43 is provided on the rotating core 4 between the first signal rotating disk 41 and the second signal rotating disk 42 .

[0019] As a further improvement, a nut 44 is provided at the tail of the rotating core 4 , and the nut 44 is pressed tightly against the second signal rotating disk 42 .

[0020] As a further improvement, a flat washer 45 is provided between the corresponding nut 44 on the rotating core 4 and the second signal rotating disk 42 .

[0021] The emergency stop pulling fork structure mentioned in the present invention can realize displacement conversion in two mutually perpendicular directions by allowing the rotating plate to swing around the support plate through the coordination of the concave and convex features of three sheet metal parts.

[0022] Specifically, the sheet metal fork connector consists of a rotating plate 1, a support plate 2, and a flat plate 3. The rotating plate 1 is inserted into the slot 21 of the support plate 2, and the flat plate 3 connects the two support plates 2 into one. The rotating plate 1 can swing around the slot of the support plate 2 without falling off.

[0023] The first signal turntable 41, the spacer 43, and the second signal turntable 42 are locked at the tail end of the rotating core 4, and the dial plate 1 is stuck in the clamping groove formed by the first signal turntable 41 and the second signal turntable 42. When the socket 5 is pulled outward, the raised part in the opening groove at the tail end of the socket 5 drives the two ends of the notch of the dial plate 1 to move, forcing the dial plate 1 to rotate. The rotation of the dial plate 1 drives the first signal turntable 41, the second signal turntable 42, and the rotating core 4 to move upward, triggering the micro switch to send an emergency stop signal. In this way, the horizontal displacement is converted into vertical displacement through the fork structure. Pull out the rotating core 4, and the clamping groove formed by the first signal turntable 41, the spacer 43, and the second signal turntable 42 drives the rotation of the dial plate 1. Under the tension of the tension spring 13, the socket 11 returns to its original state.

[0024] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
