Abstract
The invention relates to the technical field of pulleys, and discloses a derailing prevention pulley. The derailing prevention pulley comprises a clamping assembly, a pulley support connected with the clamping assembly, at least two fixed pulleys which are arranged on the pulley support and at least one movable pulley which can move up and down. The derailing prevention pulley is simple in structure and convenient to mount. The at least one movable pulley is arranged, so that when the fixed pulleys slide along the lower end face of a guide rail, the movable pulley abuts against the upper end face of the guide rail, and the pulleys are effectively prevented from derailing.
Description
Technical field
The present invention relates to pulley technical field, specifically a kind of derailing pulley.
Background technology
The sliding door of shower house is generally opened the door by pulley mobile realization on guide rail or is closed the door.Inconvenience installed by existing pulley, and pulley is when slide on rails, is easy to split away off from guide rail.Therefore, a kind of derailing pulley is needed badly.
Summary of the invention
The present invention is directed to above-mentioned Problems existing, a kind of derailing pulley is provided.
The present invention for achieving the above object, takes following technical scheme to be achieved:
A kind of derailing pulley, comprises nip assemblies, the pulley bracket be connected with nip assemblies, is arranged at least two fixed blocks on pulley bracket and at least one movable pulley moving up and down.
Preferably, described movable pulley is arranged on holder, and described holder is screwed on pulley bracket, and described holder is provided with the screwed hole matched with screw, and described screw is fixed on pulley bracket by nut.
Only need rotary screw, holder just can be made to rise with movable pulley or decline.During installation, can movable pulley be declined rotary screw, allow movable pulley and fixed block be on same level line, now be convenient to pulley to be fit into guide rail; After pulley loads guide rail, reversely rotate screw, make movable pulley increase, withstand guide rail upper surface, can effectively avoid pulley to derail in moving process.
Preferably, described fixed block is two, and described movable pulley is one, and described movable pulley is arranged in the middle part of two fixed blocks.Now, pulley structure triangular in shape, two fixed blocks slide along guide rail lower surface, and movable pulley withstands guide rail upper surface, not easily derails.
Preferably, described fixed block is two, and described movable pulley is two, described two fixed blocks and two movable pulleys parallel to each other.Compared with triangular structure, this structure makes dodge gate more steady.
Compared with prior art, beneficial effect of the present invention is as follows: structure of the present invention is simple, easy for installation, and by arranging at least one movable pulley, when fixed block slides along guide rail lower surface, movable pulley withstands guide rail upper surface, effective anti-limited slip wheel derailing.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of derailing pulley of the present invention;
Fig. 2 is the sectional drawing of a kind of derailing pulley of the present invention;
Fig. 3 is the using state figure of a kind of derailing pulley of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
See Fig. 1 ~ 3, a kind of derailing pulley, comprise nip assemblies 1, the pulley bracket 2 be connected with nip assemblies 1, be arranged at least two fixed blocks on pulley bracket 23 and at least one movable pulley 4 moving up and down, nip assemblies 1 is for being fixed on sliding door 8 by pulley.
Movable pulley 4 is arranged on holder 5, and holder 5 is fixed on pulley bracket 4 by screw 6, and holder 5 is provided with the screwed hole matched with screw 6, and screw 6 is fixed on pulley bracket 4 by nut 7.
Only need rotary screw 6, holder 5 just can be made to rise with movable pulley 4 or decline.During installation, can movable pulley 4 be declined rotary screw 6, allow movable pulley 4 and fixed block 3 be on same level line, be now convenient to pulley to be fit into guide rail 9; After pulley loads guide rail 9, reversely rotate screw 6, make movable pulley 4 increase, withstand guide rail upper surface, can effectively avoid pulley to derail in moving process.
As one of preferred version of the present invention: fixed block 3 is two, movable pulley 4 is one, and movable pulley 4 is arranged in the middle part of two fixed blocks 3.Now, pulley structure triangular in shape, two fixed blocks 3 slide along guide rail lower surface, and movable pulley 4 withstands guide rail upper surface, not easily derails.
As another preferred version of the present invention: fixed block 3 is two, movable pulley 4 is two, two fixed blocks and two movable pulleys parallel to each other.Compared with triangular structure, this structure makes dodge gate more steady.
Compared with prior art, beneficial effect of the present invention is as follows: structure of the present invention is simple, easy for installation, and by arranging at least one movable pulley, when fixed block slides along guide rail lower surface, movable pulley withstands guide rail upper surface, effective anti-limited slip wheel derailing.
Only as described above, be only the preferred embodiment of the present invention, when can not limit the scope of the invention process with this, namely generally according to equivalence change simple done by the content described in the claims in the present invention and description of the invention and modification, be all still covered by the claims of the invention.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the present invention.
