Abstract
The present invention relates to a kind of handrail strap tensioning device, this handrail strap tensioning device relates to the truss and the handrail of escalator, described truss comprises second pole and first pole, described swelling device comprises pressure zone chain and the elasticity reset device that is linked in sequence between first pole and second pole, described pressure zone chain presses in the handrail top, hence one can see that, adopt handrail strap tensioning device of the present invention, handrail is when motion, because the existence of elasticity reset device, utilization swelling device provided by the invention makes pressure zone chain tensioner handrail all the time, so can avoid handrail to come off effectively.
Description
Technical field
The present invention relates to a kind of parts that are used for staircase, especially a kind of handrail strap tensioning device.
Background technology
In the prior art, used handrail strap tensioning device generally adopts bar linkage structure, as shown in Figure 1, this bar linkage structure is installed in the pull bar 32 on the truss 4 by one and is formed with pull bar 32 other end bonded assembly set squares 31, described set square 31 is connected with the tensioner roller set 2 that is used for tensioner handrail 1, thereby the tensioner that realizes 2 pairs of handrails 1 of tensioner roller set that vertically moves by control pull rod 32, know thus, the landing of handrail very easily takes place in this structure when the handrail long-term motion, influence the operation of staircase.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of handrail strap tensioning device is provided, can realize that handrail is not easy to come off.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of handrail strap tensioning device, the truss and the handrail that relate to escalator, described truss comprises second pole and first pole, described swelling device comprises pressure zone chain and the elasticity reset device that is linked in sequence between first pole and second pole, and described pressure zone chain presses in the handrail top.
Described elasticity reset device comprise spring, spring core and with both ends of the spring bonded assembly overhead gage and lower baffle plate, described spring core one end is connected with the pressure zone chain, the other end is movable to be provided with, described overhead gage arranged outside has the locking member that is used to compress overhead gage with spring core movable end bonded assembly, and lower baffle plate then is connected with second pole.
Adopt between described spring core movable end and the locking member and be threaded.
Be connected with attaching parts between the described pressure zone chain and first pole.
Described attaching parts is L-shaped, and is described " L " shape attaching parts transverse end surface is connected with first pole by threaded connector, and its vertical top then is connected with the pressure zone chain.
According to above technical scheme, the present invention can realize following beneficial effect:
Since swelling device of the present invention comprise the pressure zone chain and with pressure zone chain bonded assembly elasticity reset device, know thus, handrail is when motion, because the existence of elasticity reset device, make pressure zone chain tensioner handrail all the time, so utilization swelling device provided by the invention can avoid handrail to come off effectively.
Description of drawings
Fig. 1 is a structural representation of using swelling device in the prior art;
Fig. 2 is a structural representation of using swelling device of the present invention.
The specific embodiment
Explain technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figure 2, handrail strap tensioning device of the present invention, the truss and the handrail that relate to escalator, described truss comprises second pole 4 and first pole 2, described swelling device comprises pressure zone chain 1 and the elasticity reset device that is linked in sequence between first pole 2 and second pole 4, described pressure zone chain 1 presses in the handrail top, described elasticity reset device comprises spring 63, spring core 64 and with spring 63 two ends bonded assembly overhead gage 62 and lower baffle plates 65, described spring core 64 1 ends are connected with pressure zone chain 1, the other end is movable to be provided with, described overhead gage 62 arranged outside have the locking member 61 that is used to compress overhead gage 62 with spring core 64 movable end bonded assemblys, lower baffle plate 65 then is connected with second pole 4, adopt between described spring core 64 movable ends and the locking member 61 and be threaded, then this locking member is a nut, be connected with attaching parts 3 between the described pressure zone chain 1 and first pole 2, this attaching parts 3 is L-shaped, described " L " shape attaching parts 3 transverse end surfaces are connected with first pole 2 by threaded connector, and its vertical top then is connected with pressure zone chain 1.
