Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] See also Figure 1 , Figure 2 The figure shows a multifunctional follow-up rope grabber, comprising a fixed plate 1, the front side of the fixed plate 1 is rotatably mounted on the movable plate 2, a collar 3 and a cam 4 are installed between the fixed plate 1 and the movable plate 2, and the collar 3 and the cam 4 are an integrated structure, the collar 3 and the cam 4 are rotatably connected to the fixed plate 1 through a positioning shaft, a coil spring 7 is fixedly sleeved on the outer side of the positioning shaft, a fixed block 11 is installed between the fixed plate 1 and the movable plate 2 on the lower side of the collar 3, and the connection between the fixed block 11 and the movable plate 2 is a fixed connection, a bolt 2 10 is threadedly installed on the front end of the movable plate 2, and the connection between the bolt 2 10 and the fixed plate 1 is a threaded connection, a blocking structure 5 is installed on the left side of the cam 4 between the fixed plate 1 and the movable plate 2, a connecting seat 8 is fixedly connected to the rear end of the collar 3 and the cam 4 positioning shaft, and the connecting seat 8 is located on the rear side of the fixed plate 1, and a limiting component 6 is installed on the outer side of the connecting seat 8 at the rear end of the fixed plate 1.
[0023] See also Figure 2 , Figure 3The blocking structure 5 includes a blocking block 501 that is slidably connected to the fixed plate 1 and the movable plate 2. Two symmetrically distributed limit pins 502 are fixedly installed at the rear end of the blocking block 501. The limit pins 502 can prevent the blocking block 501 from separating from the fixed plate 1. A limit straight groove 503 is provided on the fixed plate 1 corresponding to the limit pin 502, and the limit pin 502 is slidably connected to the fixed plate 1 through the limit straight groove 503. A sleeve 504 is fixedly installed at the center of the side of the blocking block 501 away from the cam 4.
[0024] See also Figure 3 A bolt 505 is movably embedded inside the sleeve 504, and the connection between the bolt 505 and the fixed plate 1 is a threaded connection. The bolt 505 is located inside the sleeve 504 and one end is fixedly connected to a limiting plate 506, and the bolt 505 is rotatably connected to the sleeve 504 through the limiting plate 506. The limiting plate 506 can prevent the bolt 505 from detaching from the sleeve 504.
[0025] The working principle that can be adjusted according to the rope model is as follows: the user first rotates the movable plate 2 to open, places the rope between the cam 4 and the blocking block 501, and then rotates the bolt 1 505 to move the blocking block 501, so that the blocking block 501 and the cam 4 are close to the rope, but the rope can still move between the cam 4 and the blocking block 501. The position of the blocking block 501 can be adjusted by the bolt 1 505, which is conducive to the use of the rope grab with various types of ropes, effectively expanding the use range of the rope grab. The user then rotates the movable plate 2 to close, locks the fixed plate 1 and the movable plate 2 by the bolt 2 10, and buckles the lock of the safety rope on the ring 3 through the fixed plate 1 and the movable plate 2. When a fall occurs, the ring 3 will drive the cam 4 to rotate, and the rotation of the cam 4 cooperates with the blocking block 501 to clamp the rope, preventing the rope grab from continuing to move on the rope, thereby avoiding a fall accident.
[0026] Embodiment 2
[0027] See also Figure 4 This embodiment further explains the first embodiment. Two symmetrically distributed rollers 9 are rotatably embedded on one side of the blocking block 501 close to the cam 4 , and the two rollers 9 are close to the two ends of the blocking block 501 .
[0028] In this embodiment, the roller 9 installed on the blocking block 501 can reduce the friction between the blocking block 501 and the rope, so that the rope grab can be used as a pulley in a safe environment, and the rope grab has other practical functions.
[0029] Embodiment 3
[0030] See also Figure 4 , Figure 5This embodiment further explains the second embodiment. The limit assembly 6 includes a mounting seat 601 fixedly connected to the fixing plate 1. A limit block 602 that can move up and down is movably embedded at the lower end of the mounting seat 601. The limit block 602 is plugged and unplugged with the connecting seat 8 through a plug-in slot. The limit block 602 is inserted into the plug-in slot on the connecting seat 8 to prevent the ring 3 and the cam 4 from rotating. The outer side of the limit block 602 is located inside the mounting seat 601 and two symmetrically distributed top beads 603 are installed. The top bead 603 is located inside the mounting seat 601 and is fixedly connected to a spring 604 at one end.
[0031] See also Figure 5 Two rows of symmetrically distributed spherical slots 605 are provided on the outer side of the limit block 602, and the top ball 603 is movably connected with the limit block 602 through the spherical slot 605. The top ball 603 is inserted into the spherical slot 605 to position the limit block 602. A dial button 606 is fixedly installed on the outer side of the limit block 602, and the connection between the dial button 606 and the mounting seat 601 is a sliding connection.
[0032] In this embodiment, when the rope grab is used as a pulley in a safe environment, the user moves the limit block 602 downward by the dial button 606, so that the limit block 602 is inserted into the insertion groove on the connecting seat 8. The connecting seat 8 and the cam 4 are limited by the limit block 602, which is helpful to prevent the cam 4 from rotating and jamming the rope when the rope grab is used as a pulley, and the top ball 603 is embedded in the spherical groove 605 on the limit block 602, which can lock the position of the limit block 602.
