Embodiment Construction

[0039] like figure 1 Schematic diagram of the installation structure of the flexible safety gear linkage mechanism of the household ladder; figure 2 The schematic diagram of the right safety gear is as follows:

[0040] A flexible safety tongs linkage mechanism for household ladders. The left and right safety tongs 2 with a tong body and a lifting rod are installed on the left and right vertical beams 6 and 7 of the car respectively, and are linked by the linkage rod. The pull rod is linked with the crank through the linkage shaft to form a universal linkage mechanism. The linkage rod 3 has left and right pull rods 31, 32. One end of the left pull rod 31 is connected to the left crank 51 linked with the pull rod of the left safety gear. One end is connected to the blue screw 10; one end of the right pull rod 32 is connected to the right crank 52 linked with the pull rod 21 of the right safety gear, and the other end is connected to the left pull rod 31 through the blue screw...

Abstract

The invention discloses a flexible safety gear linkage mechanism for a home elevator. Left and right safety gears with gear bodies and lifting rods are arranged on left and right vertical beams of a cage respectively, and are linked through a linkage rod, wherein the lifting rods are linked with cranks to form a universal linkage mechanism through a linkage shaft; the linkage rod is provided with left and right pull rods; one end of the left pull rod is connected with the left crank linked with the lifting rod of the left safety gear, and the other end of the left pull rod is connected with a turnbuckle; one end of the right pull rod is connected with the right crank linked with the lifting rod of the right safety gear, and the other end of the right pull rod is connected with the left pull rod through the turnbuckle. The linkage mechanism has the advantages that the linkage mechanism is flexible and reliable in structure and higher in safety; the linkage mechanism is simple in design and high in practicability; the linkage mechanism is convenient to operate, and gaps between the safety gears and guide rails are relatively easy to regulate; the linkage mechanism is smaller in size and applicable to the home elevator; the linkage mechanism can be regulated leftwards and rightwards, and is difficult to lock.

Description

technical field [0001] The invention relates to a flexible safety gear linkage mechanism for a household ladder, which relates to a linkage mechanism that can be flexibly lifted and pulled on the household ladder safety gear, and the distance between the guide rail and the brake block of the safety gear is relatively easy to adjust and is not easy to be stuck. Background technique [0002] The elevator safety gear device is under the control of the speed limiter. When the elevator speed exceeds the limit speed set by the elevator speed limiter, or when the suspension rope breaks and relaxes, it will stop the car in an emergency and clamp it on the guide rail. A safety device on the It provides effective protection for the safe operation of the elevator, and is generally installed on the car frame or counterweight frame. Safety gear is divided into one-way safety gear and two-way safety gear, but due to the complicated manufacturing process, two-way safety gear has not yet b...
