The two ends of described rope are engaged with respectively an erection loop for the rope connection.
Described rope stretches out on this end in gap positioning piece is installed, and is used for preventing retracting after rope is inserted in the upper end line of rabbet joint of window frame inner slide and breaking away from slide block.
The installation position, bottom of described strip groove seat is open type groove position, and, be provided with mild circular lead angle in this open type groove position.
Described connector is the molding type metalwork.
Described spring is piano wire level spring.
The utility model has the following advantages after having adopted such scheme:
1, load-bearing precisely, to need not adjustment, service free, location and installation and maintenance simple, and efficient is high;
When 2, lifting lightly freely, smooth noiselessness, without frictional resistance, feel is splendid.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of drawing device of the present utility model.
Fig. 3 is the structural representation of strip groove seat of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
1 to shown in the accompanying drawing 3 with reference to the accompanying drawings, the present embodiment is described for the pulley type handle system of vertical sliding window up and down, the interior drawing device 2 of groove that it includes the strip groove seat 1 of the galvanized steel that is installed between window frame and the sash and is assemblied in this strip groove seat 1, described drawing device 2 includes spring 3, rope 4, connector 5, this leading block 6 of leading block 6(is through unique design, can not only eliminate the noise and can prevent that limited slip wheel twists) and separate the first rotating pulley 7 and the second rotating pulley 8(rotating pulley is smooth, low frictional properties and prevent the performance such as distortion, guaranteed the smooth-going and uniformity of operation), wherein, it is to be engaged on rope 4 two ends with special technique that the two ends of the described rope 4 of the present embodiment are engaged with respectively this stainless steel erection loop 11 of stainless steel erection loop 11(that connects for rope 4, it is pulled out used intensity of force from rope 4 must be greater than the twice of its institute's load-bearing, namely be the twice of its maximum load, guaranteed like this its reliability); Described leading block 6 correspondences are plugged on the connector 5, simultaneously, the first rotating pulley 7 is assemblied on this connector 5 by rotating dog, and, this connector 5 is near an end of leading block 6 and an end hook joint of spring 3, and this connector 5 is near an end of the first rotating pulley 7 and stainless steel erection loop 11 hook joints of rope 4 one ends; The other end correspondence of described spring 3 is colluded on the top of strip groove seat 1 pin 9, simultaneously, the second rotating pulley 8 is installed on the installation position, bottom 10 of this strip groove seat 1 by the rotating dog correspondence, and, be formed with the gap of passing for rope 4 between the groove bottom land of this second rotating pulley 8 and strip groove seat 1; The other end of described rope 4 stretches out from above-mentioned gap after walking around successively the circumferential annular groove of the second rotating pulley 8 and the first rotating pulley 7, simultaneously, this end at rope 4 is equipped with positioning piece 12, be used for preventing that rope 4 is inserted into interior rear the retraction and the disengaging slide block of the upper end line of rabbet joint of window frame inner slide, satisfy matching requirements.The installation position, bottom 10 of the described strip groove seat 1 of the present embodiment is open type groove position, and simultaneously, for the safety that operates, the present embodiment is provided with mild circular lead angle in this open type groove position, causes installation and maintenance simple.In addition, the described connector 5 of the present embodiment is the molding type metalwork, and this part is compressing through the high pressure punch die by metal, and metal defect is few, and durability strengthens greatly.In addition, the described spring 3 of the present embodiment is piano wire level spring, and this high-quality metal has the anti-fatigue performance of superelevation, the performance that it has, higher with cold bundle steel and the spring produced through oil-quenched ordinary steel than other, thus can effectively guarantee total quality and the performance of drawing device.Also have because strip groove seat of the present utility model 1 adopts the galvanized steel manufacturing, for the characteristic of galvanized steel, so that it has maximum intensity, corrosion resistance, thereby the durability of product is maximized.In a word, after adopting above scheme, because the pulley structure of setting up, this pulley type handle system is in the process that sash is closed, and external force required when spring 3 is stretched is little, and moves smoothly, and noise is low, and feel is splendid; And when sash was raised, the power that stores in spring 3 was released, by native system design so that it can provide the 40%-50% fan heavy auxiliary pulling force, thus when effectively having realized lifting up and down lightly freely.
The examples of implementation of the above are the preferred embodiment of the utility model only, are not to limit practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
