Abstract
The utility model discloses a safety window device, which comprises a safety limiting unit. The safety limiting unit comprises a main body, a connecting piece, a roller and an elastic piece. One end of the connecting piece is pivoted with the main body, and the other end of the connecting piece is connected with the roller. The elastic piece is connected with the main body and is butted with the connecting piece. The roller is connected with the connecting piece through a shaft.
Description
Technical field
The utility model relates to elevator field, relates in particular to a kind of security window device of lift car.
Background technology
The security window device of tradition car, when safe sash lock rotates, lock pin inserts limit switch, thereby plays the effect of close circuit.Yet the bending of lock pin often causes lock pin not stick into smoothly limit switch and trigger circuit.
Utility model content
The technical matters that the utility model solves is to provide a kind of comparatively simple and safe security window device.
A kind of security window device, it comprises safe spacing unit and security window, described safe spacing unit comprises main body, attaching parts, roller, elastic component and switch ring, described attaching parts one end is articulated in described main body, the other end connects described roller, described elastic component be connected with described main body and butt described in attaching parts, described roller shaft is connected to described attaching parts, described switch ring is arranged on described security window, described switch ring has breach and the contiguous described roller setting of circular arc, and the breach of the circular arc of described switch ring can block described roller.
Further, described security window is provided with turning cylinder, and described switch ring is to be welded on the turning cylinder of described security window.
Further, described security window device also comprises safe sash lock, and the contiguous described security window of described safe sash lock edge arranges.
Compared with prior art, security window device of the present utility model comprises safe spacing unit, and when described security window is opened, described safe spacing unit tightens up thereupon, and car circuit disconnects.And described security window is when closing, described safe spacing unit resets thereupon and unclamps, car circuit turn-on.The utility model operates comparatively simple and safety.
Accompanying drawing explanation
Fig. 1 is the plan sketch of an embodiment of security window device of the present utility model;
Fig. 2 is a side schematic view of the device of security window shown in Fig. 1, and wherein, security window is closed;
Fig. 3 is a side schematic view of the device of security window shown in Fig. 1, and wherein, security window is opened.
The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, an embodiment of the utility model security window device comprises security window 1, safe sash lock 2 and safe spacing unit 3.Described security window 1 is arranged on car top, and it has rectangular configuration.The contiguous described security window of described safe sash lock edge is arranged on described security window.The corner of described safe spacing unit 3 contiguous described security windows 1 arranges.
Described safe spacing unit 3 comprises main body 30, attaching parts 31, roller 32, elastic component 33 and switch ring 34.Described main body 30 is connected with the circuit of car.Described attaching parts 31 one end are articulated in described main body, and the other end connects described roller 32.Described elastic component 33 be connected with described main body 30 and butt described in attaching parts 31.Described roller 32 is coupling in described attaching parts 31.The contiguous described roller of described switch ring 34 is arranged on the outside, corner of described security window 1, described switch ring 34 has the breach of circular arc, when described security window 1 is closed, and roller 32 described in the breach butt of described switch ring 34, described elastic component 33 is in releasing orientation, and car circuit is connected.In the present embodiment, described security window 1 is provided with turning cylinder, and described switch ring 34 is welded on the turning cylinder of described security window 1.
When rotating described safe sash lock 2 and opening described security window 1, described switch ring 34 is exerted pressure to car direction displacement and to described roller 32, make described roller 32 drive described attaching parts 31 to compress to described main body 30 directions, thus described elastic component 33 in tightening up state, car circuit disconnects.When described security window 1 is closed again, described switch ring 34 resets, and drives described roller 32 and attaching parts 31 together to reset, and described switch ring 34 blocks described roller 32.Described elastic component 33 is got back to releasing orientation, the conducting again of car circuit.
In above-mentioned embodiment, described safe spacing unit 3 is as limit switch, and when described security window 1 is opened, described safe spacing unit 3 tightens up thereupon, and car circuit disconnects.And described security window 1 is when closing, described safe spacing unit 3 resets thereupon and unclamps, car circuit turn-on.Compared to prior art, adopt lock pin to insert the mode of limit switch, the utility model operates comparatively simple and safety.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
