Technical field
This utility model relates to sun blind parts machining technical field, a kind of stay cord lockset for wooden louvres curtain.
Background technology
Sun blind are available for covering the opening of window and door, in order to intercept light and keep privacy.Vane type sun blind are to be made up of some blades or impeller, and respectively this blade all can rotate independently about a rotating shaft and be opened by shutter and Guan Bi.It is typically the holding rod turn utilizing to be mounted connected on a gear mechanism, or pulls a chain engaged with a gear mechanism, and use control and make these blades rotate.Sun blind are made up of numerous blades, when blade all closes, are had by shutter blind pull rope, pull bracing wire, get final product rollup blades, pull the most to the right bracing wire, and blade answers auto lock, keep corresponding roll-up state, neither continue upper volume, and the most do not get loose downslide.Existing sun blind lockset, is made up of lock body, copper wheel etc., it be by stay cord by the fixing seat of upper beam directly to lockset, the copper wheel in utilizing lockset blocks stay cord and completes the folding and unfolding positioning function of blade.
At present, traditional lockset mostly uses copper wheel or other metallic sheaves to be fixed on the inside of housing by axle, this results in during using, owing to the friction between metal can bring bigger noise, affect work or the life of people, simultaneously, traditional metallic sheave is fixed by axle, there is also card rope phenomenon, drastically reduce the service life causing lockset, motility and versatility are low；Furthermore, metal material is replaced with traditional plastic material, although can have greatly improved in terms of noise, but, the wearability extreme difference of plastic material, growth over time, it is easy to that the phenomenon that abrasion is the most serious occurs, it is unfavorable for the life-time service of product, needs being replaced of timing, this adds increased the acquisition cost of product.It addition, traditional rope Locking device mostly uses gear structure, manufacturing procedure is more complicated, and the cycle of processing is longer, relatively costly, and keeps in repair replacing inconvenience.
Utility model content
The purpose of utility model: in order to overcome above deficiency, this utility model discloses a kind of stay cord lockset for wooden louvres curtain, has that noise is little, anti-wear performance good, and installs the features such as replacing is convenient, structural strength is big.
Technical scheme: in order to realize object above, the utility model discloses a kind of stay cord lockset for wooden louvres curtain, including U-shaped housing, pulley, interior U-shape lock sheet, outer U-shape lock sheet, pulley rotation pin and locking plate rotational pin；Described pulley is fixed between U-shaped housing by pulley rotation pin；Described interior U-shape lock sheet is located at inside outer U-shape lock sheet, and the two is fixed between U-shaped housing by described locking plate rotational pin；Described pulley rotation pin is vertical at the top of locking plate rotational pin；It is provided with plastic bushing between described pulley and U-shaped housing；Described plastic bushing is formed by the left and right two parts docking run through within pulley axis hole.
A kind of stay cord lockset for wooden louvres curtain described in the utility model, it is provided with plastic bushing between described pulley and U-shaped housing, described plastic bushing is formed by the left and right two parts docking run through within pulley axis hole, by increasing plastic bushing, on the one hand avoid pulley to contact with U-shaped housing and the direct of pulley rotation pin, the noise reducing contact between metal and produce, on the other hand also reduces the friction noise between pulley rotation pin, and described pulley can rotate around plastic bushing.It addition, realize the locking of stay cord by described interior U-shape lock sheet and cooperating of outer U-shape lock sheet, simple in construction, installation are changed conveniently, the process-cycle is short, reduce the processing cost of product.
Further, a kind of stay cord lockset for wooden louvres curtain described in the utility model, the material of described pulley is metal material.Owing to pulley needs long-time and stay cord contact slide, using metal material, improve the anti-wear performance of pulley, service life is long, reduces pulley repair and replacement cost.
Further, a kind of stay cord lockset for wooden louvres curtain described in the utility model, described interior U-shape lock sheet is provided with conductor rope groove.Carried out the arrangement of stay cord by conductor rope groove, and carry out pressing locking by outer U-shape lock sheet, it is achieved the locking of stay cord, simple in construction, easy care, processing cost are low.
Further, a kind of stay cord lockset for wooden louvres curtain described in the utility model, the bottom of described U-shaped housing is provided with waist type rope guiding hole；The bottom of described waist type rope guiding hole sets with raised edge.For waist-shaped hole compares circular port, range of activity is bigger, and is fixedly connected by the edge protruded so that connects fixing more firm, does not haves rotation phenomenon, good stability.
Further, a kind of stay cord lockset for wooden louvres curtain described in the utility model, the side of described U-shaped housing is provided with " one " font reinforcement.Improve the surface strength of U-shaped housing, prevent the phenomenon that torsional deformation occurs under by the pulling force effect of stay cord, it is ensured that the safety in utilization of product, improve service life.
Further, a kind of stay cord lockset for wooden louvres curtain described in the utility model, described pulley rotation pin and the riveting of locking plate rotational pin are fixed on U-shaped housing.By riveting process, on the one hand make fixing more firm, on the other hand ensure service life, cannot be loosened after.
Technique scheme is it can be seen that a kind of stay cord lockset for wooden louvres curtain described in the utility model has the advantages that
A kind of stay cord lockset for wooden louvres curtain described in the utility model, it is provided with plastic bushing between described pulley and U-shaped housing, described plastic bushing is formed by the left and right two parts docking run through within pulley axis hole, by increasing plastic bushing, on the one hand avoid pulley to contact with U-shaped housing and the direct of pulley rotation pin, the noise reducing between metal contact and produce, the friction noise between the least and pulley rotation pin, described pulley can rotate around plastic bushing.It addition, realize the locking of stay cord by described interior U-shape lock sheet and cooperating of outer U-shape lock sheet, simple in construction, installation are changed conveniently, the process-cycle is short, reduce the processing cost of product.The technical program is by using the technical scheme of metallic sheave collocation plastic bushing, both the demand of pulley anti-wear performance had been met, decrease the noise produced in sliding process, do not have card rope phenomenon simultaneously yet, simultaneously, arranging reinforcement on U-shaped housing, it is ensured that the structural strength of U-shaped housing, service life is long；This utility model also has that processing cost is low, easy care, easily change, and has the biggest market competitiveness.
