Problems solved by technology

[0006] In order to overcome the problem that the descender in the prior art cannot realize the coexistence of the one-handed operation function and the automatic protection function, it is difficult for the user to operate in special occasions such as fire rescue, and the user has no grip feeling when turning the control handle. It is difficult to judge whether the control handle is turned in place, and it is difficult for operators without professional training to quickly grasp the technical problems of the method of use. A multi-mode eccentric wheel anti-panic descender is provided. The descender can realize when the hands are off the rope. The automatic protection function and one-handed operation function coexist, which can effectively improve the rescue efficiency in special occasions such as fire rescue. In addition, when the handle is turned in place, the user will feel the step change of the rotation resistance, which is not suitable for operators without professional training. extremely friendly

Embodiment 1

[0041] Such as Figure 1 to Figure 9 As shown, a multi-mode eccentric wheel anti-panic descender includes a descender base plate 1, an auxiliary friction wheel 2 and an eccentric brake friction wheel 3 are installed on the descender base plate, and a first lock hole 4 is provided on the descender base plate. The first lock hole is located on the side of the eccentric brake friction wheel away from the auxiliary friction wheel. The eccentric brake friction wheel is provided with a limit chute 5, and the bottom plate of the descender is fixed with the eccentric wheel limit shaft matched with the limit chute. 6. The side of the eccentric wheel limit shaft close to the auxiliary friction wheel is provided with an eccentric wheel fixed rotation shaft 7. The eccentric brake friction wheel can rotate relative to the bottom plate of the descender through the eccentric wheel fixed rotation shaft. The auxiliary friction wheel and the eccentric brake friction A braking gap 8 for threadin...

Embodiment 2

[0051] Figure 10 Shown is a schematic diagram of the descender in the descending state in the second mode of use, and the second mode of use is more suitable for users with good professionalism. When adopting the second mode of use, the upper end of the rope is connected to a fixed anchor point or a protection station, and the lower end of the rope passes through the descender to form a grip end. The eccentric brake friction wheel is located above the auxiliary friction wheel, and the rope After winding upwards from the lower edge of the eccentric braking friction wheel, then winding downwards along the upper edge of the auxiliary friction wheel and passing through, the part of the rope in contact with the eccentric braking friction wheel and the auxiliary friction wheel rotates approximately 45 degrees counterclockwise. ° "S" type. The second use mode can realize one-hand operation. Compared with the first use mode, the contact friction parts between the rope and the eccent...

Embodiment 3

[0054] Figure 11 Shown is a rock-climbing protector, which includes a lemon-shaped installation base plate, on which a state switching component is arranged. The rock-climbing protector can realize the anti-panic function, and cannot realize the second descent mode described in Embodiment 2. When the limit boss of the trigger is embedded in the limit groove of the trigger force member, the downward mode can be maintained by maintaining an appropriate grip on the handle. When the user grips the handle tightly due to panic, the trigger and the trigger force member will When disengagement occurs, it will automatically enter the self-locking protection state, thereby realizing the anti-panic function.

Abstract

In order to solve the technical problems that in the prior art, a descender cannot achieve coexistence of a single-hand operation function and an automatic protection function, and the operation difficulty of a user is large when the descender is applied to special occasions such as fire rescue, the invention provides a multi-mode eccentric wheel anti-panic descender. The multi-mode eccentric wheel anti-panic descender comprises a descender bottom plate, an auxiliary friction wheel and an eccentric brake friction wheel are installed on the descender bottom plate, a first lock hole is formed in the descender bottom plate, a limiting sliding groove is formed in the eccentric brake friction wheel, an eccentric wheel limiting shaft cooperating with the limiting sliding groove is fixed to the descender bottom plate, an eccentric wheel fixing rotating shaft is arranged on the side, close to the auxiliary friction wheel, of the eccentric wheel limiting shaft, the eccentric brake friction wheel can rotate relative to the descender bottom plate through the eccentric wheel fixing rotating shaft, a brake gap used for allowing a rope to penetrate through is formed between the auxiliary friction wheel and the eccentric brake friction wheel, and the eccentric brake friction wheel is provided with a state switching assembly assisting the descender in being switched from a self-locking state to a descending state.

Description

technical field [0001] The invention relates to the technical field of high-altitude slow-descent devices, in particular to a multi-mode eccentric wheel anti-panic descent device. Background technique [0002] The descender is a protective device used in outdoor training, mountaineering, extreme, outdoor and other sports scenes or rescue scenes to protect the operator. [0003] The Chinese patent with the application number CN201020216676.1 discloses a rope brake descender, which includes a fixed side plate and a movable side plate that is rotatably connected to the fixed side plate through a first pin shaft, and the first pin shaft is covered with There is a movable wheel with a groove on the outer periphery that can rotate with the movement of the rope and a control handle, the movable wheel is located between the fixed side plate and the movable side plate, the control handle is connected to the movable Wheel linkage; the fixed side plate on the upper part of the movable...
