Abstract
The utility model relates to a novel armrest belt tensioning device which relates to a truss and an armrest of escalator, wherein the truss comprises a first support rod and a second support rod, thetensioning device comprises a press belt chain and an elastic reset device which are sequentially connected between the second support rod and the first support rod, the press belt chain is tightly pressed on the armrest belt; thereby, when the armrest belt tensioning device is in use, the armrest belt is continuously tensioned by the press belt chain because of the elastic reset device during themoving process of armrest belt so that the novel armrest belt tensioning device is utilized to effectively avoid armrest belt from falling off.
Description
Technical field
The utility model relates to a kind of parts that are used for staircase, especially a kind of novel 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 forms with pull bar 32 ' other end bonded assembly set square 31 ' institute, described set square 31 ' is connected with the tensioner roller set 2 ' that is used for tensioner handrail 1 ', thereby realize the tensioner of tensioner roller set 2 ' to handrail 1 ' by vertically moving of 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.
The utility model content
The utility model provides a kind of novel handrail strap tensioning device at the deficiencies in the prior art, can realize that handrail is not easy to come off.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of novel handrail strap tensioning device, the truss and the handrail that relate to escalator, described truss comprises first pole and second pole, described swelling device comprises pressure zone chain and the elasticity reset device that is linked in sequence between second pole and first 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 second pole.
Described attaching parts is the lock clasp structure.
According to above technical scheme, the utility model can be realized following beneficial effect:
Since swelling device described in the utility model 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 the swelling device that utilization the utility model provides 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 described in the utility model.
The specific embodiment
Explain the technical solution of the utility model below with reference to accompanying drawing.
As shown in Figure 2, handrail strap tensioning device described in the utility model, relate to moving staircase girders and handrail, described truss comprises first pole 4 and second pole 2, described swelling device comprises pressure zone chain 1 and the elasticity reset device that is linked in sequence between second pole 2 and first pole 4, and pressure zone chain 1 presses in the handrail top, described elasticity reset device comprises spring 53, spring core 54 and with spring 53 two ends bonded assembly overhead gage 52 and lower baffle plates 55, described spring core 54 1 ends are connected with pressure zone chain 1, the other end is movable to be provided with, described overhead gage 52 arranged outside have the locking member 51 that is used to compress overhead gage 52 with spring core 54 movable end bonded assemblys, lower baffle plate 55 then is connected with second pole 4, adopt between described spring core 54 movable ends and the locking member 51 and be threaded, then this locking member is a nut, be connected with attaching parts 3 between the described pressure zone chain 1 and second pole 2, because not stopping transport of handrail is moving, the motion that elasticity reset device is not stopped, thereby the tensioner handrail that the pressure zone chain is not stopped, therefore attaching parts 3 is also ceaselessly being done extensional motion, so the used attaching parts 3 of the utility model is the lock clasp structure, can guarantee that then the suffered power of attaching parts 3 is pressure longitudinally, therefore the intensity of attaching parts 3 can not be affected, and promptly it does not have the danger of fracture.
