The locking member 205 is used to lock the two forms of the seat 201, and the sliding member 206 is used to cooperate with the ladder to achieve up and down movement.

[0036] Specifically, guardrails 201 a are provided on the backrest 203 and the cushion plate 204 ; the guardrails 201 a are convenient for fixing the injured person and preventing the injured person from falling when sitting on the seat 201 .

[0037] Example 2

[0038] Reference Figure 2 to Figure 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the backrest 203 is provided with a middle groove 203a, a side groove 203b, a notch 203c, a column groove 203d, and a side plate 203e. The middle groove 203a is provided in the middle of the backrest 203 and runs through the top of the backrest 203. The side grooves 203b are staggered on the side walls of the backrest 203. The middle grooves 203a are connected. The notch 203c is provided below the bottom side groove 203b. The column groove 203d is provided below the notch 203c. The side plate 203e is provided below the side wall of the backrest 203; a rotation groove 203f is formed between the side plate 203e and the side wall of the backrest 203; the pad 204 is provided with a connecting block 204a, and the connecting block 204a is located in the rotating groove 203f and rotates with the rotating groove 203f.

[0040] Torsion springs (not shown in the figure) are arranged in the pad 204 and the rotating groove 203f, so that the backrest 203 and the pad 204 are at 90 degrees in the initial state, that is, the chair shape.

[0041] Specifically, the sliding member 206 includes a gear 206a, a first clamping plate 206b, a tooth plate 206c, and a second clamping plate 206d. The gear 206a is rotatably arranged in the middle groove, the first clamping plate 206b and the second clamping plate 206d are slidably arranged in the side groove 203b, and the tooth plate 206c is slidably matched with the middle groove 203a and meshes with the gear 206a.

[0042] Specifically, the first clamping plate 206b is L-shaped, and the first clamping plate 206b is provided with a rack 206f and a roller 206g. The rack 206f is arranged at one end of the first clamping plate 206b and meshes with the gear 206a; the roller 206g is rotatably arranged on a side of the first clamping plate 206b close to the side wall of the ladder 202; the side wall of the ladder 202 is provided with a groove 202a, and the groove 202a is slidably matched with the roller 206g; the roller 206g is used to improve the smoothness of the seat 201 during the lifting process.

[0043] The upper part of the tooth plate 206c is connected to the rope 104, and the tooth plate 206c is pulled upward. Since the tooth plate 206c is meshed with the gear 206a, the tooth plate 206c moves upward so that the first clamping plate 206b and the second clamping plate 206d of the armrest located on both sides of the backrest 201 move closer to each other until the ladder 202 is clamped. After the ladder 202 is clamped by the first clamping plate 206b and the second clamping plate 206d, the first clamping plates 206b and the second clamping plates 206d on both sides cannot move closer; at this time, the gear 206a and the tooth plate 206c cannot move either, and finally the entire seat 201 is lifted under the pulling force of the rope 104. After the seat 201 is transported and landed, the tooth plate 206c moves downward under its own gravity, causing the gear 206a to rotate clockwise, so that the first clamping plate 206b and the second clamping plate 206d on both sides move away from each other, and the seat 201 is separated from the ladder 202, so that the conveyor frame can be quickly installed and detached, so that the workers who are injured in the high-altitude environment such as the top of the tower can be quickly transported down and rescued in time.

[0044] Specifically, the second clamping plate 206d is provided with a connecting rod 206e on the basis of the first clamping plate 206b. The connecting rod 206e is arranged below the second clamping plate 206d and slidably cooperates with the notch 203c.

[0045] Specifically, the locking member 205 includes a rotating column 207 and a locking rod 205a, the rotating column 207 is rotatably disposed in the column groove 203d; a straight groove 204b is penetrated through the side wall of the connecting block 204a, and the locking rod 205a is slidably disposed in the straight groove 204b;

[0046] The connecting rod 206e is used to drive the rotating column 205a to rotate. The rotation of the rotating column 205a is used to drive the locking rod 205a to move. The locking rod 205a moves to different positions to lock and unlock the shape of the seat 201.

[0047] Specifically, the rotating column 207 is provided with an annular groove 207a, a spiral groove 207b, an arc groove 207c, and an oblique groove 207d. The annular groove 207a, the spiral groove 207b, and the arc groove 207c are all provided on the side wall of the rotating column 207. The oblique groove 207d is provided on the end surface of the rotating column 207 and is slidably matched with the locking rod 205a. The spiral groove 207b is connected to one end of the annular groove 207a and is slidably matched with the connecting rod 206e. The backrest 203 is also provided with a torsion spring 203g and a stopper 203h. The stopper 203h is provided in the column groove 203d and is slidably matched with the arc groove 207c. The torsion spring 203g is provided between the arc groove 207c and the end surface of the stopper 203h.

[0048] The annular groove 207a is arranged at one end of the spiral groove 207b close to the side plate 203e, and the distances between the two ends of the inclined groove 207d and the axis of the rotating column 207 are not equal. The axis of the rotating column 207 is colinear with the rotating axis of the backrest 203 and the pad 204. It is worth noting that in the initial state, the torsion spring 203g is at its original length. At this time, the connecting rod 206e is located in the annular groove 207a, at the intersection with the spiral groove 207b, and the locking rod 205a is located at one end of the inclined groove 207d close to the axis.

[0049] Specifically, the side plate 203e is further provided with a slide groove 205b, which is slidably matched with an end of the locking rod 205a away from the rotating column 207; the slide groove 205b includes a horizontal section 205c, an arc section 205d, and a vertical section 205e, and the horizontal section 205c and the vertical section 205e are arranged at both ends of the arc section 205d;

[0050] It is worth noting that the horizontal section 205c and the vertical section 205e are both extended along the end of the arc segment 205d away from its center, and the center of the arc segment 205d is concentric with the rotating column 207 and the rotating axis of the backrest 203 and the pad 204. In the initial state, the locking rod 205a is located at the intersection of the arc groove 205d and the horizontal groove 205c.

[0051] When the seat 201 is connected to the ladder 202, the second clamping plate 206d moves inward, causing the connecting rod 206e to move into the spiral groove 207b, thereby driving the rotating column 207 to rotate, so that the locking rod 205a moves along the horizontal groove 205c driven by the inclined groove 207d. When the seat 201 is connected to the ladder 202, the connecting rod 206e moves to the end of the spiral groove 207b, one side of the locking rod 205a moves to the end of the inclined groove 207d away from the axis, and the other side moves to the end of the horizontal groove 205c. At this point, the backrest 203 and the pad 204 cannot rotate, and the chair form is locked. After the seat 201 is disengaged from the ladder 202, each component is reset, and the locking rod 205a moves back to the initial position. At this time, the pad 204 is rotated to 180° with the backrest 203. At this time, the seat 201 becomes a bracket form, and the straight groove 204b and the vertical section 2 05e overlaps, during this process, the locking rod 205a is located in the arc segment 205d and moves, and can drive the rotating drum 207 to rotate in the opposite direction (in this process, the connecting rod 206e is located in the annular groove 207a and will not limit the rotation of the rotating drum 207). When the pad 204 is 180° with the backrest 203, the rotating drum 207 is reset. At this time, the inclined groove 205d drives the locking rod 205a to move to the end of the vertical section 205e and the straight groove 204b. At this point, the backrest 203 and the pad 204 cannot rotate, and the bracket form is locked, thereby realizing the rapid state of the chair form and the bracket form, saving rescue time. When the bracket form needs to be released, it is only necessary to manually move the locking rod 205a to the intersection of the vertical section 205a and the arc segment 205d, and the seat 201 can be reset to the initial state under the drive of the torsion spring (not shown in the figure) arranged in the pad 204 and the rotating groove 203f.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
