Description

The slope roof window spring lock

Technical field

The utility model relates to the switch control structure of slope roof window, more precisely is a kind of slope roof window spring lock.

Background technology

Slope roof window can directly be installed on the inclined slope roof of sky, it has good daylighting position, regardless of the angle at sunshine, all can provide sufficient sunshine for loft, the old man and the children that are fit to needs sunlight live, its adopt in outstanding opening ways, for indoor diverse location is provided change the wind passage, made things convenient for the replacement of room air and extraneous new wind.Window position and the special sound insulation processing of slope roof window towards sky make the privacy of the interior space, quiet degree that great improvement all be arranged, and be suitable to work-at-home space or study.

Slope roof window not only can play decoration function, and can well daylighting.Slope roof window has been called for sunlight and air, give between stiff pitched roof and brought vitality, it has given the light in our dark, give us the chances of getting close to nature more, and thus simultaneously, we have increased the eyes that a pair of is observed the world seemingly again, and as long as its rational setting height(from bottom) makes you lifting eyes and just can enjoy gently: pure and fresh bright and clear blue sky and white cloud in the daytime; Blurred it was studded with stars in flicker in the night sky; The poetic and pictorial splendor that water droplet strikes window when raining; And the disorderly graceful dancing posture of snowflake when snowing.You can have a panoramic view beautiful scenery outside window at any time like a dream, and all similarly are at arm's length, and its good air-tightness and watertightness then make you not worry that outdoor weather can influence indoor life and work.

The rated wind velocity of door and window is that door and window section and window type design main foundation, also is one of Main physical performance of door and window.The wind load ability that the main bearing member of door and window can bear in allowing deformation range is called the resisting wind press capacity of door and window

Traditional slope roof window spring lock design is gone up loosely organized, and noise is bigger, by design improved, and the novel spring lock of the described slope roof window of this utility model, compact conformation, volume is little, and profile is more attractive in appearance, has reduced noise greatly.

The utility model content

Technical problem to be solved in the utility model provides a kind of compact conformation, and volume is little, and profile is more attractive in appearance, the slope roof window spring lock that noise is little.

In order to address the above problem, the utility model is taked following technical scheme:

A kind of slope roof window spring lock, comprise base, dead bolt, the dead bolt ball, semicircle connecting rod, the control rocking arm, base, shell, and return spring, the described shape shell that partly wraps is set on the first half of described base, partly wrap the shape outer casing inner wall and each side arrange a transverse slipway, in load onto and state dead bolt, it is hinged that described dead bolt stretches out an end and the dead bolt ball of shell, the other end and described semicircle rod hinge connection, open a short groove on the described connecting rod, with a hinge it is connected with the shape shell that partly wraps of base, described semicircle connecting rod is fixed on the control rocking arm, control rocking arm and base are hinged, described return spring is installed in the interior groove of base, and return spring one end is fixed on the base, and the other end is fixed on the control rocking arm.

Described outer cover suit forms interference fit with the control rocking arm, and is fixed on the control rocking arm outside the control rocking arm.

Described spring lock adopts the POM material.

The beneficial effects of the utility model are: the utility model links together dead bolt and shell by semicircle connecting rod, thereby controlled the flexible distance of dead bolt, and dead bolt can slide in partly wrapping the shape shell, than before rotational structure dwindled the volume of spring lock, make structure compact more, in conjunction with above-mentioned 2 points, the compact conformation of whole spring lock, volume is little, and profile is more attractive in appearance, and, reduced noise greatly in slideway because dead bolt slides.

The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to Fig. 7, the utility model slope roof window spring lock comprises base shown in Figure 11, first half on the base 1 is provided with the shape shell 2 that partly wraps shown in Figure 5, partly wrap shape shell 2 inwalls and each side arrange a transverse slipway 3, in adorn dead bolt shown in Figure 24, limit its upper and lower displacement with the both sides slideway, it is hinged that dead bolt 4 stretches out an end and the dead bolt ball 5 of shell 1, the other end and semicircle connecting rod 6 are hinged, open a short groove 7 on the connecting rod 6 shown in Figure 3, with a hinge it is connected with the shape shell 2 that partly wraps of base 1, control dead bolt 4 flexible distances, semicircle connecting rod 6 is fixed on the control rocking arm 8 shown in Figure 4, control rocking arm 8 is hinged with base 1, return spring 9 shown in Figure 6 is installed in 10 li of grooves in the base 1, and return spring 9 one ends are fixed on the base 1, and the other end is fixed on the control rocking arm 8.Shell 2 is sleeved on outside the control rocking arm 8, forms interference fit with control rocking arm 8, is fixed on the control rocking arm 8, can rotate with rocking arm.Spring lock of the present utility model is selected for use corrosion-resistant, aging-resistant high-quality POM material has good weatherability, characteristics such as not yielding.

The unlatching of spring lock is by the control of control rocking arm, apply a power backward for the control rocking arm, make it around the axle rotation hinged, compression retracteding position spring during rotation with base, drive the motion rearward together of semicircle connecting rod and dead bolt, finish the action that spring lock is opened, dead bolt shrinks.The power that applies before removing when closing spring lock promotes the control rocking arm forward under the elastic force effect of return spring, promote semicircle connector and slip dead bolt by the control rocking arm again, makes it return to initial state, has promptly finished closing of spring lock.

The utility model links together dead bolt and shell by semicircle connecting rod, thereby controlled the flexible distance of dead bolt, and dead bolt can slide in partly wrapping the shape shell, than before rotational structure dwindled the volume of spring lock, make structure compact more, in conjunction with above-mentioned 2 points, the compact conformation of whole spring lock, volume is little, and profile is more attractive in appearance, and, reduced noise greatly in slideway because dead bolt slides.

Spring lock of the present utility model has improved old-fashioned horizontally pivoted window spring lock, makes the slope roof window switch lighter, for the user brings more convenience.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
