Detailed Implementation
[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0032] A specific embodiment of this utility model discloses a seat for escaping fire stairs, which can be connected to a slide rail used for connecting sliding escape seats in existing stairwells. For example... Figures 1-2 As shown, it includes a foldable base 1, a connecting box 2, and a clamping unit 3 for connecting to the slide. The base 1 is connected to the clamping unit 3 through the connecting box 2, so that the base 1 can slide along the slide with the clamping unit 3.
[0033] A trigger block 11 is provided on the seat body 1, and a contact element 21, a pushing component 22, and a first positioning hole 23 are provided on the connecting box 2. The clamping unit 3 includes an upper clamp 31 fixed on the connecting box 2 and a lower clamp 32 that can move along the connecting box 2. The upper clamp 31 and the lower clamp 32 cooperate to connect the seat to the slide.
[0034] In some embodiments, the base 1 is rotatably connected to the connecting box 2. By rotating the base 1, the base 1 can be unfolded or folded, and the trigger block 11 can rotate with the base 1.
[0035] When the base 1 is in the folded state, the trigger block 11 does not contact the contact member 21. One end of the contact member 21 abuts against the lower clamp 32 in the first positioning hole 23, and the other end protrudes from the connecting box 2. At this time, when the upper clamp 31 is connected to the slide, the lower clamp 32 does not contact the slide.
[0036] When the seat 1 is in the unfolded state, the trigger block 11 rotates with the seat 1, pushing the contact member 21 to push the lower clamp 32 out of the first positioning hole 23, causing the pushing component 22 to push the lower clamp 32 to move, so that the lower clamp 32 contacts the slide rail, thereby connecting the seat to the slide rail through the cooperation of the upper clamp 31 and the lower clamp 32.
[0037] In some embodiments, the connecting box 2 is also provided with a second positioning hole 24. When the lower clamp 32 is connected to the slide, the lower clamp 32 enters the second positioning hole 24, thereby fixing the position of the lower clamp 32 and making the lower clamp 32 and the slide stablely connected.
[0038] Furthermore, such as Figure 3 As shown, the lower clamp 32 includes a lower jaw 321, a positioning rod 322, and a second spring 323. The lower jaw 321 is used to connect to the slide rail. One end of the positioning rod 322 is connected to the lower jaw 321, and the other end enters the connecting box 2. A positioning head 3221 is provided on the positioning rod 322. The second spring 323 is provided between the positioning head 3221 and the connecting box 2. The second spring 323 is arranged around the positioning rod 322. The positioning head 3221 can enter the first positioning hole 23 or the second positioning hole 24 under the action of the second spring 323.
[0039] The contact element 21 includes a push head 211 and a third spring 212. The push head 211 enters the first positioning hole 23, and the third spring 212 is disposed between the push head 211 and the first positioning hole 23. When the trigger block 11 pushes the contact element 21, the push head 211 moves along the first positioning hole 23, causing the third spring 212 to be compressed. When the positioning head 3221 is in the first positioning hole 23, the push head 211 abuts against the positioning head 3221, and both the second spring 323 and the third spring 212 are in an unforced state.
[0040] Furthermore, such as Figures 1-2 As shown, the pushing assembly 22 includes a pushing head 221 and a first spring 222. One end of the pushing head 221 abuts against the positioning rod 322, and the other end is connected to the connecting box 2 through the first spring 222. The first spring 222 is in a compressed state.
[0041] In practical applications, when the seat is needed for escape, after connecting the upper clamp 31 to the slide, the seat body 1 is unfolded, causing the trigger block 11 to push the contact member 21, which pushes the positioning head 3221 out of the first positioning hole 23, releasing the fixation of the lower clamp 32. This causes the second spring 323 to be compressed, and the first spring 222 to return to its original position, driving the push head 221 to push the positioning rod 322 to move. This causes the lower clamp 321 to move along the connecting box 2 with the positioning rod 322 until the lower clamp 321 contacts the slide. At this time, the position of the positioning head 3221 corresponds to the second positioning hole 24. Under the action of the second spring 323 returning to its original position, the positioning head 3221 enters the second positioning hole 24, fixing the position of the lower clamp 32 and keeping the lower clamp 32 connected to the slide.
[0042] Preferably, multiple rollers are provided on the upper clamp 31 and the lower clamp 32. The rollers contact the slide rail, thereby reducing the friction between the clamp unit 3 and the slide rail and improving the smoothness of the seat sliding along the slide rail.
[0043] Furthermore, such as Figure 4 As shown, the connecting box 2 also includes a reset rod 25. One end of the reset rod 25 is inside the second positioning hole 24, and the other end protrudes from the connecting box 2. When the positioning head 3221 enters the second positioning hole 24, the reset rod 25 abuts against the positioning head 3221.
[0044] When the seat needs to be folded, the seat body 1 is folded, causing the trigger block 11 to release the pressure on the contact member 21. The push head 211 is reset under the action of the third spring 212. The end of the reset rod 25 protruding from the connecting box 2 is pressed, causing the reset rod 25 to push the positioning head 3221 out of the second positioning hole 24, compressing the second spring 323. The lower clamp 32 is moved until the position of the positioning head 3221 corresponds to the first positioning hole 23. Under the reset action of the second spring 323, the positioning head 3221 enters the first positioning hole 23, fixing the position of the lower clamp 32. This disconnects the clamp unit 3 from the slide rail, allowing the seat to be folded.
[0045] Compared with existing technologies, the seat for fire escape staircases of this invention features a connectable box 2 that allows the seat body 1 to connect to the clamping unit 3, enabling the seat body 1 to slide along the track with the clamping unit 3. A trigger block 11 on the seat body 1 pushes the lower clamp 32 out of the first positioning hole 23 when the seat body 1 is in the unfolded state. This causes the pushing component 22 to move the lower clamp 32, bringing it into contact with the track. The upper clamp 31 and lower clamp 32 then work together to connect the seat to the track. This design is simple to operate and allows the clamping unit 3 to connect to the track simultaneously during the unfolding of the seat body 1. The foldable seat body 1 saves space. A second positioning hole 24 fixes the position of the lower clamp 32, ensuring a stable connection between the lower clamp 32 and the track. A reset rod 25 allows the lower clamp 32 to leave the second positioning hole 24, separating it from the track and facilitating the storage and folding of the seat.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
