Embodiment

[0022] Example: such as Figure 1 to Figure 5 Shown:

[0023] A buckle adjustment mechanism for telescopic feet, comprising a positioning hole 11 opened on a telescopic foot 1 and a buckle 21 correspondingly installed on a fixed foot 2 .

[0024] The telescopic foot 1 is slidably embedded in the fixed foot 2 along the length direction.

[0025] The positioning holes 11 are two parallel rows of positioning holes, each row of positioning holes 11 is arranged along the length direction of the telescopic foot 1, and the two rows of positioning holes 11 are misaligned in the length direction of the telescopic foot 1, see figure 2 and Figure 5 .

[0026] The buckle 21 is composed of a support 211, a first pin 212, a first elastic element 213, a second pin 214, a second elastic element 215 and a pull ring 216. The support 211 is fixed on the fixed foot 2, The first pin 212 and the second pin 214 are arranged side by side on the support 211, the first elastic element 213 acts on...

Abstract

The invention relates to a stretching foot lock catch adjusting mechanism which comprises positioning holes (11) formed in a stretching foot (1) and lock catches (21) correspondingly arranged on a fixed foot (2). The stretching foot lock catch adjusting mechanism is characterized in that the positioning holes (11) are two rows of parallel positioning holes, and the two rows of positioning holes (11) are displaced in the length direction of the stretching foot (1); each lock catch (21) consists of a support (211), a first pin (212), a first elastic element (213), a second pin (214), a second elastic element (215) and a pull ring (216); the first pins (212) and the second pins (214) are matched with the positioning holes (11) alternatively to form a locking state; the pull ring (216) is pulled by an external force so that the heads of the first pin (212) and the second pin (214) are withdrawn out of the positioning holes (11) to be unlocked. The stretching foot lock catch adjusting mechanism is many in adjustment gear, convenient to operate and high in locking reliability.

Description

technical field [0001] The invention relates to the fields of ladders, scaffolding and workbenches, in particular to a telescopic foot lock adjustment mechanism for ladders, scaffolding and workbenches. Background technique [0002] In order to adapt to conditions such as uneven ground, the feet of ladders, scaffolding, and workbenches are often designed as telescopic feet, that is, a fixed foot is embedded with a telescopic foot, and the telescopic foot can slide and stretch along the length of the fixed foot. A locking mechanism is used to realize the locking of the telescopic position of the telescopic foot relative to the fixed foot. [0003] For the prior art, please refer to the utility model patent whose Chinese patent announcement number is CN202157739U. This patent discloses a three-leg telescopic ladder, the telescopic foot structure is composed of a casing (i.e. a fixed foot), a telescopic foot and a hook pin positioning mechanism. , elastic elements and multipl...
