Description
Technical Field
[0001] This invention relates to the field of doors and windows, and in particular to an integrated structure of a corner bracket and a pulley seat. Background Technology
[0002] Existing door and window transmission systems typically include pulley blocks, corner mechanisms, and door and window handles. The pulley blocks have a side-moving function, allowing the window sash to be moved to the side via the door and window handles, and also enabling the window sash to be locked and unlocked via the door and window handles. The existing connection structure of pulley block modules and corner brackets is usually as follows: one end of the actuating piece of the pulley block module is connected to the transmission rod of the door and window system, and the other end is connected to one end of the actuating rod, the other end of which is connected to the corner bracket. Furthermore, since the actuating piece is inside the pulley block, a pressure plate needs to be installed inside the pulley block to press the actuating piece into the groove to prevent it from falling off. This structure is complex and inconvenient for subsequent maintenance and replacement of the actuating piece. At the same time, during installation, the corner bracket is often installed first in the groove of the window sash profile. Then, the positions of the pulley block and the actuating piece need to be aligned. This alignment method is inflexible and prone to errors. After alignment, the installer needs to hold down the pulley block module with one hand while tightening the screws with the other, making installation difficult.
[0003] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention
[0004] To address the shortcomings and deficiencies of the prior art, this invention provides an integrated structure for the corner mechanism and the pulley base. By integrating the pulley module base and the corner mechanism into a single structure, installation can be performed by first installing the corner mechanism and then installing the pulley base module, eliminating the need to adjust the position of the actuating piece, thus saving the alignment step and making installation more convenient.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An integrated structure of a corner mechanism and a pulley base includes a corner mechanism and a pulley module, wherein the pulley module and the corner mechanism are fixedly connected; the pulley module includes a pulley base and a fixed base that can move relative to each other, the fixed base is provided with a groove, a slidable actuating piece is installed in the groove, and the pulley base is provided with an actuating post that is adapted to the actuating piece;
[0007] The cornering device has a toggle lever that passes through the slide groove, the toggle piece is provided with a first pushing part, and the toggle lever has a second pushing part that is adapted to the first pushing part.
[0008] As a preferred embodiment, the lever is located on the back of the lever and presses the lever into the groove.
[0009] As a preferred solution, one of the first pushing part and the second pushing part is a pushing column, and the other is a pushing groove matched with the pushing column.
[0010] As a preferred solution, the toggle piece is rectangular, the first pushing part has two, and correspondingly, the second pushing part on the toggle lever also has two; the two pushing grooves are centrally symmetric about the center point of the toggle piece.
[0011] The toggle piece has a toggle groove matched with the toggle column, and the toggle column is located in the toggle groove; the toggle groove extends in a strip shape, and the toggle groove is centrally symmetric about the center point of the toggle piece.
[0012] As a preferred solution, the fixing seat is provided with a positioning groove, and the corner adjuster has a shell, one end of the shell is matched with the positioning groove.
[0013] As a preferred solution, the shell is provided with a connecting lug at the position corresponding to the positioning groove, the connecting lug is provided with a screw hole, the corner adjuster is fixed with the window sash profile through the connecting lug, and the toggle lever has an outwardly extending part corresponding to the sliding groove.
[0014] As a preferred solution, the corner adjuster has a shell, and the toggle lever is partially located inside the corner adjuster.
[0015] As a preferred solution, the pulley seat is provided with a guide groove extending in a lateral direction, and the fixing seat is provided with a guide column matched with the guide groove.
[0016] A retainer is arranged between the pulley seat and the fixing seat, and a roller shaft is mounted on the retainer.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0034] Reference will now be made to the drawings, wherein Figures 1 to 9 In an embodiment of the present application, an integrated structure of a corner turner and a pulley base comprises a corner turner 10 and a pulley module 20, wherein the pulley module 20 is fixedly connected to the corner turner 10. The pulley module 20 comprises a movable pulley base 21 and a fixed base 22, wherein the fixed base 22 is provided with a sliding groove 221, and a sliding piece 222 is installed in the sliding groove 221 and is slidable. The sliding piece 222 is provided with a sliding groove 2221, and the pulley base 21 is provided with a sliding column 211 which is adapted to the sliding groove 2221.
[0035] The corner turner 10 is connected to a sliding rod 11, the sliding rod 11 penetrates the sliding groove 221, and the sliding piece 222 is provided with a first pushing part 2222. The sliding rod 11 is provided with a second pushing part 111 which is adapted to the first pushing part 2222.
[0036] In actual application, one of the first pushing part 2222 and the second pushing part 111 is a pushing column, and the other is a pushing groove. The pushing column and the pushing groove are adapted to each other, i.e. the positions of the pushing column and the pushing groove can be exchanged. In this embodiment, the first pushing part 2222 is a pushing groove provided on the sliding piece 222, and the second pushing part 111 is a pushing column provided on the sliding rod 11. In actual application, the pushing groove can be a through hole provided on the sliding piece 222 or a notch provided on the side of the sliding piece 222. In this embodiment, the pushing groove is a semicircular notch provided on the side of the sliding piece 222, and the pushing column is a cylinder provided on the sliding rod 11. Of course, the first pushing part 2222 and the second pushing part 111 can also be other shapes of cooperation, which will not be described here.
[0037] As a preferred embodiment, the knob 211 comprises a circular rotating wheel arranged at the center of the pulley base 21, which can rotate around its center, improving the knob effect of the knob groove 2221 on the knob 211, thereby improving the smoothness of the lateral movement of the fixing base 22.
[0038] Preferably, the fixing base 22 is provided with a positioning groove 223, and the corner adjuster 10 has a shell 101, one end of which is adapted to the positioning groove 223. During installation, the end is first placed in the positioning groove 223, and the shell 101 of the corner adjuster 10 is fixedly connected with the fixing base 22 of the pulley module 20 through a connecting screw to form an installation module (forming an integral structure), and then the entire installation module is installed on the door and window profile; in actual application, a transmission belt is usually arranged in the shell 101, which is a flexible belt body that can reciprocate in the curved channel in the corner adjuster 10, which is a prior art and will not be described here.
[0039] One end of the knob rod 11 is fixedly connected with the transmission belt inside the shell 101 of the corner adjuster 10 through a connecting piece, that is, the knob rod 11 of the present embodiment has been used as one of the components of the corner adjuster 10, and can be directly fixedly connected when leaving the factory, which is more convenient for the operation of the installer; as a preferred solution, the knob rod 11 and the transmission belt inside the shell 101 of the corner adjuster 10 are integrally formed, and the connecting piece is also omitted as a connection, which is more convenient for the subsequent installer to assemble the door and window transmission system.
[0040] Here, it can be supplemented that: the installation module of the present application only needs to place the corner adjuster 10 part of the installation module into the slot of the sash profile 40 during installation, and then fix the corner adjuster 10 first through a connecting screw; at this time, no matter where the knob rod 11 of the corner adjuster 10 is located (in what state), it does not affect the next step of installing the pulley module 20, that is, the pulley module 20 can be directly installed and fixed on the sash profile 40 through a fixing screw; the installation structure and installation steps of the prior art are that the corner adjuster 10 and the pulley module 20 are separately arranged, and during installation, the corner adjuster 10 is first fixedly installed on the sash profile 40, and then the pulley module 20 is installed; at this time, the installation position of the pulley module 20 needs to be determined according to the position and length of the knob rod 11 and the knob piece 222 (otherwise, the installation position is not correct, which will cause the entire sash system to be unable to be normally used, and this positioning method is difficult to position); after determining the installation position of the pulley module 20, the installer needs to hold the pulley module 20 with one hand or a tool to prevent dislocation, and operate the screw with the other hand; after installation is completed, the knob rod 11 is installed on the corner adjuster 10, and finally the knob rod 11 is connected with the knob piece 222, and the installation is completed. As can be seen from the above, the installation steps of the present application are more simple and the installation difficulty is lower.
[0041] Meanwhile, the push rod 11 of the present application is inserted through the sliding groove 221 of the base, and is located at the back of the push piece 222, the front of which is directed to the sliding groove 221; here, the front and back of the push piece 222 are opposite surfaces, so that the push piece 222 can be stably pressed in the sliding groove 221, avoiding the falling of the push piece 222; in the prior art, the connecting and matching rod of the corner turner 10 and the pulley module 20 is often provided in multiple sections. Specifically: one end of the transmission belt in the corner turner 10 of the prior art is connected to one end of the push rod 11, the other end of the push rod 11 is connected to one end of the push piece 222, and the other end of the push piece 222 is connected to the external transmission rod, which is very complicated to install, and such an installation structure cannot guarantee the stability of the movement of the push piece 222, and is prone to jamming, so a pressing piece needs to be installed on the sliding groove 221 to press the push piece 222 in the sliding groove 221; while in the present application, one end of the push rod 11 is first fixedly connected to the transmission belt inside the corner turner 10, and the other end of the push rod 11 is directly inserted through the pulley module 20 and connected to the external transmission rod; compared with the two installation methods, the present application not only simplifies the multi-section design of the transmission system, making the installation steps simpler, but also omits the pressing piece, which is more convenient and economical to install; and the subsequent maintenance and disassembly of the push piece 222 are also more convenient.
[0042] As a preferred embodiment, the push piece 222 is rectangular, the push grooves are two, and the push rod 11 is also provided with two corresponding push columns; wherein the two push grooves are symmetric about the center line of the length direction (left-right direction) of the rectangle (also symmetric about the center point of the rectangle); as mentioned before, the push piece 222 has a push groove 2221, and the push column 211 is located in the push groove 2221 during use; wherein the push groove 2221 extends in a strip shape, and the push groove 2221 is symmetric about the center point of the rectangle. In this way, when assembling the pulley module 20, if it is necessary to change the movement direction relationship between the push piece 222 and the door handle, it is only necessary to assemble the push piece 222 by turning it over, which is very convenient. However, in the prior art, due to the presence of the pressing piece, the movement direction relationship between the pulley module 20 and the door handle is fixed, and when a pulley module 20 that moves in another direction is needed, the pressing plate must be disassembled first, and then the push piece 222 must be replaced; or another pulley module 20 must be directly replaced to achieve the change of the movement direction, so the present application has the advantage of being convenient to change direction compared with the prior art. It should be noted that the rectangle mentioned in the present specification includes both a right-angled rectangle and a rounded rectangle; of course, in other embodiments, the push piece 222 can also be of other shapes, which will not be described here.
[0043] Further, the toggle lever 11 has an outwardly expanded portion 112 corresponding to the sliding groove 221, i.e. the width of the toggle lever 11 at the sliding groove 221 is greater than the width of other sections, thereby increasing the mechanical strength of the toggle lever 11 at the sliding groove 221, enhancing the toggle effect and ensuring the effectiveness of the toggle.
[0044] Preferably, the housing 101 has a pair of connecting ears 1011 extending adjacent to the positioning groove 223, and screw holes are provided on the connecting ears 1011, and the corner adjuster 10 is fixed to the sash profile through the connecting ears 1011; and on the fixed seat 22, screw holes are also provided adjacent to the positioning groove 223, and the fixed seat 22 is fixed to the sash profile through the screw holes. In this way, the screw holes (connecting holes) are provided at the connecting position of the fixed seat 22 and the corner adjuster 10, which can ensure that the center lines of the toggle lever 11 and the toggle piece 222 are on a straight line (and the straight line is parallel to the left-right direction of the sash), thereby ensuring the accuracy of the installation connection and ensuring the pushing effect of the toggle lever 11 on the toggle piece 222.
[0045] It can be supplemented that: the fixed seat 22 is provided with an avoiding groove on the opposite side of the positioning groove 223 for the toggle lever 11 to pass through, and the avoiding groove also has a positioning effect on the toggle lever 11, thereby further facilitating the positioning and cooperation of the toggle lever 11 and the toggle piece 222; preferably, the fixed seat 22 is also provided with screw holes adjacent to the avoiding groove for connecting the fixed seat 22 to the sash profile, thereby effectively ensuring the installation stability of the pulley module 20 by providing screw holes (connecting holes) on the two sides of the pulley module 20.
[0046] Preferably, the pulley seat 21 has an extension ear 212 extending on the two sides, the extension ear 212 is formed with a guide groove 213 through a stamping process, and the fixed seat 22 is provided with a guide column 23 matched with the guide groove 213; the guide groove 213 and the guide column 23 cooperatively constitute a left-right limiting mechanism of the pulley module 20, so as to avoid the left-right movement of the pulley seat 21 or the fixed seat 22 during the side movement, thereby affecting the smoothness of the side movement; compared with the dovetail groove and the dovetail column provided on the sliding block in the prior art, the limiting mechanism has a simpler manufacturing process and can further reduce the cost.
[0047] In the embodiment, the guide groove 213 is a linear strip groove; the guide column 23 is a standard part with a mushroom head (or other hardware connecting parts with a limiting head, such as a bolt), which can be easily purchased from the market and has a manufacturing advantage. The guide column 23 is preferably detachably installed on the fixed seat 22.
[0048] The fixed seat 22 comprises a frame body and a cover body, and the frame body and the cover body are assembled to form the aforementioned sliding groove 221; the frame body and the cover body are fixedly connected by screws / bolts, which simplifies the design of the mold and facilitates the rapid production of the fixed seat 22; and the guide column 23 is connected to the cover body.
[0049] The pulley seat 21 is provided with a first rotating shaft 214 arranged in a lateral direction on one side of the pulley 215, that is, the axial direction and the lateral direction of the first rotating shaft 214 are parallel (the indoor side-outdoor side); the pulley 215 is installed on the first rotating shaft 214, and the first rotating shaft 214 can be provided with two or more than two, and is kept at a certain distance, and each first rotating shaft 214 can be provided with two or more than two pulleys 215;
[0050] Further, a second rotating shaft 216 can also be arranged between the two first rotating shafts 214, and the second rotating shaft 216 is provided with a positioning wheel 217, which is located in the wheel groove of the profile in use; the positioning wheel 217 is used to contact the two inner side walls of the wheel groove, further improving the smoothness of the door and window when moving left and right. The positioning wheel 217 can be arranged to move a small distance in the lateral direction on the second rotating shaft 216, that is, the positioning wheel 217 is movably arranged on the second rotating shaft 216, so as to ensure the effective contact of the positioning wheel 217 and at least one inner side wall of the wheel groove.
[0051] Further, a roller 30 is arranged between the pulley seat 21 and the fixed seat 22, and when the fixed seat 22 and the pulley seat 21 move relatively, the roller 30 converts the sliding friction between the two into rolling friction, thereby improving the smoothness when the two move relatively. Specifically, a retainer 31 is installed on the pulley seat 21, and a plurality of rollers 30 are arranged in a row on the retainer 31, and the rollers 30 are preferably made of stainless steel. Further, the retainer 31 can be fixedly arranged on the pulley seat 21, or can be slidably arranged in the lateral direction on the pulley seat 21.
[0052] The design of the present application focuses on that it is integrated with the corner turner, so that the corner turner is directly installed first, and then the pulley seat module is installed, without the need to adjust the position of the push piece, thereby saving the alignment step and making the installation more convenient.
[0053] Secondly, through the specific arrangement of the pulley seat module, such as the push rod passing through the pulley seat, the pressing piece part is omitted, and maintenance and installation are more convenient; and through the specific structure design of the push piece, the installer only needs to place the push piece upside down to change the pushing direction relationship of the push rod to the push piece, which is very convenient.
[0054] The above merely describes preferred embodiments of the present application, and is not intended to limit the technical scope of the present application in any way. Any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application shall still fall within the technical scope of the present application.
