Abstract
The utility model provides a detection tool for a comb plate of an escalator, which comprises a handheld part, a pressure sensor, a connecting seat and a tension plate; two ends of the pressure sensor are respectively fixed between the handheld part and the connecting seat; one end of the tension plate is hinged with the connecting seat, and the other end of the tension plate is provided with a back-off of a comb structure; the utility model discloses a during the recess of step was gone into to the back-off correspondence card of broach structure, the tip of back-off was contradicted on the fishback of staircase, then artifical pulling handheld portion for fishback backward moves in order to trigger safety switch, can detect out through pressure sensor and trigger the fishback and move required dynamics, this simple structure, convenient to use, direct card go into and stimulate can.
Description
Technical Field
The utility model relates to a staircase detection device technical field, in particular to staircase fishback detects instrument.
Background
Staircase present wide use is in various markets, the fishback is all installed to the end of present staircase, when the object card between step and fishback, can give an extrusion force of fishback, drive the fishback backward movement, trigger inside safety switch, thereby signals lets staircase stop work, avoid causing the accident, the security performance is improved, and all need test the fishback before the staircase uses, present detection device installs on the step, along with the operation of step, when the conflict is on the fishback, detect out the fishback atress size through the tensiometer, this structure is complicated, still need install during the use, use inconveniently, consequently, still need improve.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an escalator fishback detection tool carries and solves the problem of mentioning in the background art.
In order to achieve the above object, the present invention provides the following technical solutions:
a comb plate detection tool for an escalator comprises a hand-held part, a pressure sensor, a connecting seat and a tension plate; two ends of the pressure sensor are respectively fixed between the handheld part and the connecting seat; one end of the tension plate is hinged with the connecting seat, and the other end of the tension plate is provided with a back-off of a comb structure.
To the further description of the present invention, the handle portion is a pull ring structure.
For further description of the utility model, the tension plate is in a horizontal state, and the upper right side of the tension plate is provided with a connecting lug; the reverse buckle is arranged at the left lower part of the tension plate; the tension plate is hinged with the connecting seat through the connecting lug.
To the further description of the present invention, the reverse buckle is a "V" shaped structure, and the "V" shaped opening faces the right.
The utility model has the advantages that:
the utility model discloses a during the recess of step was gone into to the back-off correspondence card of broach structure, the tip of back-off was contradicted on the fishback of staircase, then artifical pulling handheld portion for fishback backward moves in order to trigger safety switch, can detect out through pressure sensor and trigger the fishback and move required dynamics, this simple structure, convenient to use, direct card go into and stimulate can.
Drawings
Fig. 1 is an overall structure diagram of the present invention.
Detailed Description
The invention is further explained below with reference to the drawings:
as shown in fig. 1, the escalator comb plate detection tool comprises a hand-held part 1, a pressure sensor 2, a connecting seat 3 and a tension plate 4; two ends of the pressure sensor 2 are respectively fixed between the handheld part 1 and the connecting seat 3; one end and the connecting seat 3 of pulling force board 4 are articulated, and the other end is equipped with the back-off 41 of broach structure, during the use, correspond through back-off 41 and go into the recess of step tail end, and the tip of back-off 41 is contradicted on the fishback of staircase, then manual pulling handheld portion 1 for the fishback moves in order to trigger safety switch, can detect out through pressure sensor 2 and trigger the fishback and move required dynamics.
In this embodiment, the handheld portion 1 is a pull ring structure, which facilitates manual pulling.
The tension plate 4 is provided with a connecting lug 42 at the upper right part in a horizontal state; the reverse buckle 41 is arranged at the lower left of the tension plate 4; the tension plate 4 is hinged to the connecting seat 3 through the connecting lug 42, the reverse buckle 41 is of a V-shaped structure, the V-shaped opening faces the right, force can be conveniently generated through the arrangement, and the tooth-disengaging imagination in the pulling process is prevented.
The above description is not intended to limit the technical scope of the present invention, and any modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
