Detailed Implementation
[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] See Figures 1-4 This utility model provides a technical solution:
[0026] Example:
[0027] like Figures 1-4 As shown, a safety protection device for cleaning outdoor building glass curtain walls includes a lock body 1 and a movable arm 2. The lock body 1 has a C-shaped structure and a locking plate 3 is provided at the first end of the lock body 1. The movable arm 2 has a column structure and the first end of the movable arm 2 is rotatably connected to the second end of the lock body 1 through a connecting shaft 13. The second end of the movable arm 2 is provided with a slot 4 that is adapted to the locking plate 3. The connecting shaft 13 is provided with a first reset member.
[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the movable arm 2 is provided with a self-locking sleeve 14 that can slide along the axial direction of the movable arm 2. When the locking piece 3 enters the slot 4, the upper end of the self-locking sleeve 14 automatically moves toward the locking piece 3 to be located outside the locking piece 3.
[0029] The self-locking sleeve 14 is a circular sleeve coaxial with the movable arm 2, and a second reset member 5 is provided between the self-locking sleeve 14 and the movable arm 2.
[0030] The self-locking sleeve 14 is provided with a first self-locking hole 6, and the movable arm 2 is provided with a second self-locking hole 9 coaxial with the first self-locking hole 6.
[0031] The first self-locking hole 6 is provided with a first self-locking post 7, and the first self-locking post 7 is provided with a third reset member 8 on the outside;
[0032] like Figure 3 and Figure 4 As shown, a second self-locking post 10 is provided inside the second self-locking hole 9, and a fourth reset member 11 is provided outside the second self-locking post 10. When the upper end of the self-locking sleeve 14 is located outside the locking plate 3, the first end of the second self-locking post 10 extends into the first self-locking hole 6 and the end face of the first end of the second self-locking post 10 is in close contact with the end face of the first self-locking post 7.
[0033] The first reset element is a torsion spring, and the second reset element 5 and the third reset element 8 are both springs.
[0034] The end of the first self-locking pin 7 that is away from the second self-locking pin 10 is a spherical structure.
[0035] The first self-locking hole 6 and the second self-locking hole 9 are both located on the inner side of the movable arm 2.
[0036] The self-locking sleeve 14 has anti-slip grooves 12 on its outside to facilitate sliding.
[0037] The lock plate 3 and the lock body 1 are an integrated structure.
[0038] Working principle: One end of the connecting rope is fixedly tied to the lock body 1, and the other end is connected to the safety rope. The connecting rope is connected to the operator's buckle or rope loop through the lock body 1. The specific operation is as follows: Press the first self-locking pin 7 with your finger. The first self-locking pin 7 squeezes the second self-locking pin 10, causing the second self-locking pin 10 to disengage from the first self-locking hole 6. At this time, the self-locking sleeve 14 can slide along the axis of the movable arm 2.
[0039] When the finger presses the first self-locking pin 7 until it enters the first self-locking hole 6, the finger (preferably the index finger, which is located on the inside of the first self-locking pin 7 when the hand is clenched) contacts the anti-slip groove 12 (the anti-slip groove 12 increases the friction between the self-locking sleeve 14 and the finger, thus facilitating the sliding of the self-locking sleeve 14). The finger moves downward, and the friction drives the self-locking sleeve 14 to move towards the connecting shaft 13. When the upper end of the self-locking sleeve 14 disengages from the locking piece 3 (slot 4), the movable arm 2 can rotate along the connecting shaft 13.
[0040] At this time, press the movable arm 2 / connecting sleeve with your finger (preferably your thumb) to apply an inward force to the movable arm 2, thereby driving the movable arm 2 to rotate around the connecting shaft 13; at this time, the buckle or rope loop can be put into the lock body 1. After the buckle or rope loop enters the lock body 1, release your thumb, the movable arm 2 returns to its original position, the locking piece 3 enters the slot 4 and then you release your index finger, the self-locking sleeve 14 automatically moves downward towards the locking piece 3. When the self-locking sleeve 14 moves to the point where the first self-locking hole 6 and the second self-locking hole 9 are coaxial, the self-locking sleeve 14 is in place, and the upper end of the self-locking sleeve 14 can prevent the locking piece 3 from disengaging from the slot 4; while the second self-locking pin 10 enters the first self-locking hole 6, which can axially limit the self-locking sleeve 14 to prevent the self-locking sleeve 14 from moving vertically.
[0041] Meanwhile, the first self-locking pin 7 is located on the inside, which can greatly reduce the risk of the self-locking pin being accidentally pressed.
[0042] This invention achieves self-locking between the movable arm and the lifting device by setting a self-locking sleeve, which can greatly reduce the risk of disengagement / hooking caused by accidental pressing of the movable arm during the use of the safety rope; at the same time, the self-locking sleeve can be used to load and unload the safety rope simply by sliding up and down, making the operation simple and quick.
