[0019] Example

[0020] like Figure 1-9 As shown, a descent protector comprises a protector body 1 and a rope control part 2, wherein the rope control part 2 comprises a base 2a and a control mechanism 2b, wherein the control mechanism 2b is pivotally arranged on the base 2a; the base 2a can be slidably arranged on the protector body 1 up and down, and a reset tension spring 4 is arranged between the protector body 1 and the base 2a, and the protector body 1 and the base 2a are provided with a hook hole 3; the protector body 1 and the rope control part 2 can be in a closed or open state by controlling the base 2a and rotating the control mechanism 2b; when the protector body 1 and the rope control part 2 are in a closed state, a curved rope walking channel S is formed between the protector body 1 and the rope control part 2, and when the protector body 1 and the rope control part 2 are in an open state, a rope can be loaded into or taken out of the curved rope walking channel S.

[0021] like Figure 6 As shown, in the actual design process, a plurality of long rows of grooves (2a1) can be designed on the base 2a and fixed to the protector body 1 with a pin, so that the base 2a and the protector body 1 can be slidably connected up and down.

[0022] Preferably, the control mechanism 2b includes a crescent-shaped bridge plate 2b1 and a control handle 2b3, the crescent-shaped bridge plate 2b1 is movably set on the control mechanism body through a bolt shaft 2b4, and a rope clamping protrusion 2b1-1 is provided on the crescent-shaped bridge plate 2b1 at the lower side of the pivot position of the bolt shaft 2b4, and a control movable block 2b2 is pivotally set on the crescent-shaped bridge plate 2b1 at the upper side of the pivot position of the bolt shaft 2b4, and the control handle 2b3 is pivotally set at a position close to the control movable block 2b2.

[0023] More preferably, a control convex point 2b2-1 is provided at the movable connection position between the control movable block 2b2 and the crescent-shaped bridge plate 2b1, and the control convex point 2b2-1 is higher than the outer curved surface of the crescent-shaped bridge plate 2b1 in a natural state.

[0024] More preferably, the protector body 1 is provided with a first engaging position 1a cooperating with the bolt shaft 2b4, and when the protector body 1 and the rope control part 2 are in a closed state, the bolt shaft 2b4 is engaged in the first engaging position 1a.

[0025] More preferably, a second engaging position 1 b is further provided at the upper end of the protector body 1 , and when the protector body 1 and the rope control part 2 are in a closed state, the control mechanism body is engaged with the second engaging position 1 b .

[0026] More preferably, the control handle 2b3 is in the shape of a bird's head, and the bird's beak of the control handle 2b3 is located close to the control movable block 2b2. The control handle 2b3 can drive the control movable block 2b2 and then drive the crescent-shaped bridge plate 2b1 to rotate along the bolt shaft 2b4, and further drive the rope clamping protrusion 2b1-1 to release or lock the rope in the curved rope walking channel S.

[0027] More preferably, the control handle 2b3 is further provided with a limit rod 2b3-1, and the control handle 2b3 is also provided with a reset torsion spring, and the limit rod 2b3-1 can prevent the control handle 2b3 from driving at an excessive angle.

[0028] More preferably, a V-shaped rope-gripping groove 1c is provided on the protector body 1 at the position of the rope outlet S1 of the curved rope-walking channel S. The V-shaped rope-gripping groove 1c can effectively prevent the rope outlet S1 from being mistaken for the rope inlet when in use, and the free end of the hand rope will be stuck in the V-shaped rope-gripping groove 1c during rappelling and the rappelling operation cannot be completed, so that the operator needs to use it in the correct assembly mode before normal rappelling operation can be performed, thereby improving the safety of the descent protector.

[0029] The working principle and the description of the usage are as follows: during operation, the control mechanism 2b is mainly used to continuously lock and release the rope in the curved rope walking channel S to achieve the purpose of slow descent and improve safety.

[0030] like Figure 1 As shown, hold the protector body 1 with your left or right hand, press the control mechanism 2b of the rope control part 2 with your index finger and middle finger to move the base 2a of the rope control part 2 and the control mechanism 2b downward to the nearby Figure 2 The state shown in the figure is made so that the bolt shaft 2b4 is disengaged from the first engaging position 1a, and the rotating control mechanism 2b and the base 2a are at a certain angle, such as Figure 3 or Figure 4As shown, at this time, the rope can be loaded into or removed from the curved rope channel S; after loading or removing the rope from the curved rope channel S, the rotating control mechanism 2b returns to the initial position, and the rope control part 2 moves upward as a whole under the action of the reset spring 4, and the bolt shaft 2b4 is smoothly inserted into the first clamping position 1a again; this operation can complete the opening and closing work of the protector body 1 and the rope control part 2, and the rope can be loaded into or removed from the curved rope channel S smoothly.

[0031] like Figure 5-Figure 9 As shown, the rope is locked and released during the use of the descent protector to achieve a slow descent process.

[0032] like Figure 5 The state shown is A, the user connects the hook 5 to the hook hole 3, the hook 5 is also connected to the safety belt worn by the operator, and the rappelling rope is loaded into the curved rope channel S. The rope at one end of the rope outlet S1 of the curved rope channel S is a fixed end connected to the high-altitude object, and the rope at one end of the rope inlet S2 of the curved rope channel S is the free end of the rappelling rope, which is controlled by the operator to achieve rappelling. Before rappelling, the rope is in a stretched and relaxed state, the control handle 2b3 is in a closed state, and the crescent-shaped bridge plate 2b1 and the control movable block 2b2 are also in a free and unstressed state.

[0033] like Figure 6 The figure shows the state B, when the user starts the rappelling activity. Due to the weight of the human body on the hook 5, it is quickly pulled downwards. At this time, the crescent-shaped bridge plate 2b1 is moved to the right by the force of the rappelling rope at the position of the pivoted control movable block 2b2. Figure 6 The middle rope 6 is in position; the crescent-shaped bridge plate 2b1 further rotates around the bolt axis 2b4. Due to the lever principle, the rope-locking protrusion 2b1-1 is set on the crescent-shaped bridge plate 2b1 to lock the descent rope in the curved rope channel S. At this time, the control handle 2b3 is still in a closed state, and the operator stays in mid-air.

[0034] like Figure 7 The C state is shown, the operator opens the control handle 2b3 and prepares to control the rope descent. The control protrusion 2b2-1 of the control movable block 2b2 is pressed to the right by the position of the rope 6, causing the control movable block 2b2 to rotate a certain angle and abut against the control handle 2b3 until the control movable block 2b2 is flush with the outer arc surface of the crescent-shaped bridge plate 2b1.

[0035] like Figure 8In the D state shown, the operator starts to hold the protector body 1 and pinches the control handle 2b3 with the middle finger and index finger, and continuously pinches or releases the bird's beak position of the bird's head-shaped control handle 2b3 to drive the control movable block 2b2 to move to the left, and then drives the upper end of the crescent-shaped bridge plate 2b1 to move to the left, and further the crescent-shaped bridge plate 2b1 rotates along the bolt shaft 2b4 to drive the rope-locking protrusion 2b1-1 to continuously release or lock the rope in the curved rope walking channel S to realize the function of slow descent, which is safe and reliable.

[0036] like Fig. 9 The E state is shown. When the operator feels that the rope is descending too fast and panics during the rappelling process, the first reaction is to hold the control handle 2b3 tightly. At this time, the bird's beak position of the bird's head-shaped control handle 2b3 is convenient for controlling the movable block 2b2 to disengage and return to the position of the movable block 2b2. Figure 6 In the B state shown, the rope-locking protrusion 2b1-1 provided on the crescent-shaped bridge plate 2b1 locks the descent rope in the curved rope-walking channel S and stops the slow descent, and stays in mid-air. If it is necessary to continue the slow descent, the operation of the C state and the D state can be repeated. Therefore, the safety is high, the operation can be performed by both hands, and the operation is convenient, which overcomes the problem that the traditional descent protector is easy to panic and cause misoperation or inconvenience in operation during use.
