Detailed implementation manners

[0026] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0027] As Figures 1-3 shown, the present utility model provides a quick release device applied to a safety evacuation system, including an outer shell 1, an electromagnet 2, a dial block 3, a push-pull rod 4, a first spring 5, a locking member 6 and a pull ring 7; the dial block 3 is rotatably connected to the outer shell 1; the push-pull rod 4 is slidably arranged along a first direction and has a farthest travel point and a nearest travel point relative to the pull ring 7; the first spring 5 is arranged along the first direction and can contact the locking member 6; the locking member 6 is located inside the outer shell 1 and is connected to the push-pull rod 4, and the locking member 6 has a clamping form and a release form as the push-pull rod 4 moves; wherein, when the push-pull rod 4 is at the farthest travel point, the first spring 5 is deformed, the dial block 3 abuts against the push-pull rod 4, the locking member 6 is in the clamping form, and the locking member 6 locks the pull ring 7, when the electromagnet 2 drives the dial block 3 to rotate, the first spring 5 returns to its original shape, the push-pull rod 4 slides from the farthest travel point to the nearest travel point, the locking member 6 is in the release form, and the locking member 6 releases the pull ring 7.

[0028] With the attached Figure 2Based on the positional relationship in it, the first spring 5 is horizontally arranged, and the push-pull rod 4 slides left and right. The linkage process of this embodiment is as follows: In the initial state, the pull ring 7 and the housing 1 are respectively connected to different ropes, the pull ring 7 is separated from the locking member 6, and the locking member 6 is in a tripped state; when the pull ring 7 is gradually inserted into the housing 1 to the left and cooperates with the locking member 6, the locking member 6 drives the push-pull rod 4 to move from the nearest point of travel to the farthest point of travel to the left. The push-pull rod 4 gradually compresses the first spring 5 to increase its elastic force. At the same time, the push-pull rod 4 gradually contacts the right end of the block 3 and drives the block 3 to rotate clockwise until the push-pull rod 4 abuts against the left end of the block 3 and the block 3 is reset. At this time, the push-pull rod 4 cannot cross the block 3, ensuring that the locking member 6 switches to the clamping state and realizing the locking and fixing of the pull ring 7; when rapid tripping is required, the electronic control system connected to the electromagnet 2 controls the electromagnet 2 to be energized, so that the electromagnet 2 pushes the block 3 to rotate clockwise. The push-pull rod 4 gradually disengages from the block 3 and moves from the farthest point of travel to the nearest point of travel to the right under the elastic force of the first spring 5, so that the locking member 6 switches from the clamping state to the tripped state, and the pull ring 7 is tripped from the locking member 6.

[0029] Specifically, the block 3 is hinged to the output rod of the electromagnet 2. When the electromagnet 2 is energized, the iron core on the electromagnet 2 moves towards the block 3, driving the block 3 to rotate through the output rod, thereby releasing the elastic force of the first spring 5.

[0030] This application combines the electronic control method of the electromagnet 2 with the mechanical linkage structure to achieve the rapid tripping of the vehicle, with rapid action response and good structural safety.

[0031] In this embodiment, a chamber 101 is provided inside the housing 1, the locking member 6 is hidden in the chamber 101, sliding grooves 102 are respectively provided on the upper and lower sides of the housing 1, and the push-pull rod 4 is slidably connected to the sliding grooves 102; specifically, the electromagnet 2 and the block 3 are respectively located on the upper side of the housing 1, the push-pull rod 4 extends into the housing 1 and is connected to the locking member 6, and at the same time, some components are hidden by the chamber 101, making the structure of the entire tripping device more compact.

[0032] In this embodiment, the top of the push-pull rod 4 is configured as a triangular block portion 401. When the push-pull rod 4 slides from the nearest point of travel to the farthest point of travel, the hypotenuse of the triangular block portion 401 contacts the bottom of the block 3. When the push-pull rod 4 is at the farthest point of travel, the right-angled side of the triangular block portion 401 contacts the side portion of the block 3.

[0033] To attach Figure 2Based on the positional relationship in [reference], when the push rod 4 slides to the left, the triangular block portion 401 contacts the bottom of the dial block 3 and pushes the dial block 3 to rotate clockwise until the triangular block portion 401 passes over the dial block 3. Finally, under the elastic force of the first spring 5, its right-angled side contacts the left side surface of the bottom of the dial block 3 to achieve the locking effect.

[0034] In this embodiment, in order to reserve a sliding space for the push rod 4 and provide a carrier for other components at the same time, a bracket 103 is erected on the top of the housing 1, and the electromagnet 2 and the dial block 3 are respectively arranged on the bracket 103. Specifically, the transverse ends of the push rod 4 extend outward to both sides of the bracket 103. In this way, the shape of the push rod 4 is roughly T-shaped, and the convenience of the structure of the bracket 103 is used to provide a stable sliding track for the push rod 4 to avoid shaking during the sliding process of the push rod 4.

[0035] In this embodiment, as shown in the appendix Figure 3 As shown, the locking member 6 includes two clamping plate portions; any one of the clamping plate portions includes a first clamping plate 601 and a second clamping plate 602. One end of the first clamping plate 601 is hinged to the push rod 4, the other end of the first clamping plate 601 is hinged to one end of the second clamping plate 602, and the other end of the second clamping plate 602 is configured as a clamping end 6021. The second clamping plate 602 is rotatably connected to the housing 1 through a fixed shaft 603; wherein, when the locking member 6 is in the clamping state, the two clamping ends 6021 are closest, and when the locking member 6 is in the unclamping state, the two clamping ends 6021 are farthest. The leftward sliding of the push rod 4 drives the first clamping plate 601 to expand outward, the second clamping plate 602 to rotate clockwise, and the clamping end 6021 to clamp the pull ring 7 inward to achieve the purpose of locking the pull ring. The rightward sliding of the push rod 4 drives the first clamping plate 601 to retract inward, the second clamping plate 602 to rotate counterclockwise, and the clamping end 6021 to loosen the pull ring 7 outward to achieve the purpose of unclamping the pull ring.

[0036] To facilitate connecting two first clamping plates 601 to the same push rod 4, the bottom of the push rod 4 is configured as a connecting rod portion 402, and the connecting rod portion 402 is hinged to the first clamping plate 601.

[0037] In this embodiment, based on the positional relationship in the appendix Figure 2 In order to facilitate the reset of the dial block 3 after rotation, a second spring 8 is connected between the housing 1 and the dial block 3, and the second spring 8 is deformed when the dial block 3 rotates. Specifically, one end of the second spring 8 is connected to the dial block 3 and the other end is connected to the bracket 103. When the dial block 3 rotates clockwise, the second spring 8 is stretched, and the second spring 8 helps the dial block 3 to reset, achieving the effect of preventing jamming.

[0038] In this embodiment, based on the appendix Figure 2Based on the positional relationship in it, a polished rod 9 is provided on the outer shell 1, and the first spring 5 is sleeved on the polished rod 9. The polished rod 9 is hidden inside the bracket 103 and arranged in the left-right direction. When the first spring 5 is sleeved on the polished rod 9, its left end abuts against the side surface of the bracket 103 and its right end is a free end.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
