Abstract
The utility model discloses a stepless lifting device of a casement sash. The stepless lifting device comprises a window frame side frame and a casement sash side frame embedded in a sliding chute of the window frame side frame, wherein an inclined strut piece is arranged between the window frame side frame and the casement sash side frame and comprises a mounting part mounted and fixed in a mounting groove of the casement sash side frame and an inclined strut part obliquely extending toward the window frame side, and a roller tightly pressed at the bottom of the sliding chute through elasticity of the inclined strut part is mounted at the extending end of the inclined strut part. The stepless lifting device of the casement sash is simple in structure, the inclined strut piece and the roller are supported between the window frame side and the casement sash side frame, the roller is tightly pressed in the sliding chute by means of elasticity provided by the inclined strut piece, and the movable casement sash can be suspended in any position by means of rolling friction force of the roller, so that stepless lifting is realized; the roller and the sliding chute are in rolling contact, so that the casement sash is pulled easily for lifting, the operation is facilitated, and the work is reliable; and moreover, the abrasion between components is further reduced by means of rolling friction, and the service life is prolonged.
Description
Technical field
The utility model relates to window setting technique field, especially relates to the lifting gear for movable sashes is installed.
Background technology
In current movable sashes, have wherein can oscilaltion, especially Adjustable screen window, conventionally formed by fixed sash and movable sashes, movable sashes is inlaid in oscilaltion in the chute of window frame.Traditional movable sashes is normally carried out lifting location by some grades of location teeth groove to it, can only be elevated to limited several positions, and positioning tooth easy fatigue damage, makes it lose elevating function.Existing movable sashes can realize stepless lifting, and what it adopted is a kind of elasticity sliding wedge, and when external force rises sash, elasticity sliding wedge can slide easily in chute; While cancelling external force, utilize the deadweight of sash to strut elasticity sliding wedge, make the two side of two side compression chutes of elasticity sliding wedge, thereby sash is fixed up; When drop-down sash, in the time that external force is greater than the frictional force between sliding wedge and chute, can realize the decline of sash.Because this elasticity sliding wedge and chute are that sliding friction contacts, easily occur along with service time is long wearing and tearing affecting its application life, and when drop-down sash, need very large strength, operation inconvenience, even there will be friction self-locking and cannot be drop-down.
Utility model content
The technical problems to be solved in the utility model is to provide the stepless lifting erecting device of the sash of a kind of simple in structure, easy operating, long service life.
For solving the problems of the technologies described above adopted technical scheme: a kind of stepless elevating means for tables of sash, include window frame side frame and be inlaid in the sash side frame in the chute of window frame side frame, it is characterized in that: between window frame side frame and sash side frame, be provided with a bracing element, this bracing element has to be fixed on the installation portion in the mounting groove of sash side frame and the diagonal brace portion of tiltedly stretching towards window frame side frame, and the elongated end of diagonal brace portion is provided with the roller that relies on the elasticity of diagonal brace portion to be pressed on chute bottom land.
The beneficial effect that adopts the utility model to bring: the utility model is simple in structure, adopt bracing element and roller to support between window frame side and sash side frame, the elastic force providing by bracing element is pressed on roller in chute, utilizing the force of rolling friction of roller that movable sashes can be hanged fixes on optional position, realizes stepless lifting.Because roller and contacting of chute are the contacts of rolling, easily pull sash lifting, convenient operation, reliable operation.And rolling friction also significantly reduces the wearing and tearing between device, extend application life.
Brief description of the drawings
Fig. 1 is the structural representation (window frame side frame and sash side frame partial cutaway) of the stepless elevating means for tables of the utility model sash.
Detailed description of the invention
As shown in Figure 1, a kind of stepless elevating means for tables of sash, include window frame side frame 1 and be inlaid in the sash side frame 2 in the chute 11 of window frame side frame 1, between window frame side frame 1 and sash side frame 2, be provided with a bracing element 3, this bracing element 3 has to be fixed on the installation portion 31 in the mounting groove 21 of sash side frame 2 and the diagonal brace portion 32 of tiltedly stretching towards window frame side frame 1, and the elongated end of diagonal brace portion 32 is provided with the roller 4 that relies on the elasticity of diagonal brace portion 32 to be pressed on chute 11 bottom lands.
Concrete, bracing element 3 can adopt steel spring plate to be stamped to form, and roller 4 can adopt plastic cement roller.Bracing element 3 is arranged in the sash side frame 2 of sash both sides, can lay according to the size of sash multiplely, the installation portion of bracing element 3 31 is fastened in the mounting groove 21 of sash side frame 2 with threaded fastener 5, and roller 4 toward the outer side.When installation, sash is forced into along the chute of window frame, utilize the elastic force providing of bracing element to make roller 4 be pressed on the bottom land of chute 11, roller 4 can provide enough force of rolling frictions that movable sashes can be hanged and fix on optional position, while needing lifting movable sashes, only need external force to overcome the force of rolling friction sliding window sash of roller 4, just can realize the stepless lifting of sash.
