Description

Technical Field

[0001] The utility model relates to the field of door and window transmission systems, and particularly to an annular transmission system. Background Art

[0002] The corner fitting is one of the commonly used hardware fittings for doors and windows. As a part of the door and window transmission system, it is installed in the window sash. Its function is to connect other hardware parts on two sides of the window sash to realize the linkage of the door and window hardware system. The existing door and window transmission systems have closed-loop designs and non-closed-loop designs; however, they all drive the entire transmission system by pulling or pushing one end of the transmission belt; and, because the transmission belt of the existing corner fitting has a large resistance when being pushed, a greater pushing force is required, so generally a transmission rod with a larger size (better strength) is needed to ensure normal and effective pushing; and the installation groove (also called "C" groove) for installing the transmission rod on the existing window sash profile is usually made according to the standard (European standard), and the installation space is fixed. Therefore, when other hardware fittings need to be installed in the installation groove, the transmission rod often needs to be cut off, and then the hardware fitting is installed at the cut-off position and correspondingly connected to the transmission rod at the cut-off position, and the installation steps are very troublesome.

[0003] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

[0004] In order to solve the defects and deficiencies of the above-mentioned prior art, the utility model provides an annular transmission system. By designing a door and window transmission system, which is a closed-loop design and realizes more labor-saving and smoother transmission by pulling the two ends of the transmission device; and based on the design of the entire annular transmission system, the size of the transmission rod can be made smaller, so that it is not necessary to cut off the transmission rod of the present application, and the installation of the entire door leaf system structure can be completed by passing the transmission rod through the hardware fitting (such as a transmission slider), and the installation is more convenient.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] An annular transmission system includes 4 corner fittings and 4 transmission rods. The 4 corner fittings and 4 transmission rods are alternately connected and enclose a ring shape; the corner fitting has a flexible component, and the corner fitting is connected to the corresponding transmission rod through the two ends of the flexible component.

[0007] At least one of the 4 transmission rods is a handle rod, and a handle for driving the movement of the handle rod is installed on the handle rod. When the handle rod moves towards one end of it, the handle rod pulls the other 3 transmission rods and 4 flexible components towards one end of itself. When the handle rod moves towards the other end of it, the handle rod pulls the other 3 transmission rods and 4 flexible components towards the other end of itself.

[0008] As a preferred solution, at least one of a side extrusion module, a support module, a lateral locking module, and a tightening module is installed on the annular drive system.

[0009] As a preferred solution, the tightening module includes a first tightening block, a second tightening block, and an adjustment screw for pushing the two blocks closer to or away from each other. One of the first tightening block and the second tightening block is connected to one end of the flexible component, and the other is connected to one end of the transmission rod.

[0010] As a preferred solution, the four corner turners are arranged at the four corners of a rectangle, and the four transmission rods are arranged along the four sides of the rectangle. The ends of the transmission rods are directly connected to one end of the flexible components of the corresponding corner turners.

[0011] The transmission rod is installed with a transmission slider, and the transmission slider has an installation through groove for the transmission rod to pass through the transmission slider.

[0012] As a preferred solution, the corner turner includes a base, and the base has a through channel for the flexible component to pass through. At least one end of the flexible component is partially exposed outside the base.

[0013] As a preferred solution, at least one end of the flexible component is installed with a connection head for connecting the transmission rod; the connection head has a first connection structure for connecting with the flexible component and a second connection structure for connecting with the transmission rod.

[0014] As a preferred solution, the first connection structure is a buckle post arranged on the connection head, and the flexible component has a buckle hole adapted to the buckle post.

[0015] As a preferred solution, the second connection structure is a connection groove arranged on the connection head. A connection hole is arranged on the outer surface of the connection head and communicates with the connection groove. The transmission rod is made of aluminum.

[0016] As a preferred solution, the flexible component is a metal strip.

[0017] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, it mainly designs a door and window drive system, which is a closed-loop design. By pulling the two ends of the actuator, it is more labor-saving and the transmission is smoother; and based on the design of the entire annular drive system, the size of the transmission rod can be made smaller, so that it is not necessary to cut off the transmission rod of this application, and the installation can be completed by passing the transmission rod through the hardware fittings (such as the transmission slider), and the installation of the entire door leaf system structure is also more convenient.

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings. Obviously, the described embodiments are only the preferred embodiments of the present utility model.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0043] Referring to the attached Figures 1 to 19 , in an annular drive system in an embodiment of this utility model, it includes 4 corner deflectors 40 and at least 4 drive rods 31 for connecting the corner deflectors 40. The drive rods 31 and the corner deflectors 40 are sequentially connected to form a ring; the corner deflector 40 has a flexible member 42, and both ends of the flexible member 42 of the corner deflector 40 are connected to the corresponding drive rod 31; preferably, the 4 corner deflectors 40 are arranged at the four corners of a rectangle, and the 4 drive rods 31 are arranged along the four sides of the rectangle. The ends of the drive rods 31 are directly or indirectly installed and connected to the corresponding corner deflectors 40, thereby connecting the 4 corner deflectors 40 to form a ring (closed-loop system);

[0044] At least 1 of the 4 drive rods 31 is a handle rod, and a handle 32 for driving the movement of the handle rod is installed on the handle rod. When the handle rod moves towards one of its ends, the handle rod pulls the other 3 drive rods 31 and the 4 flexible members 42 towards one of its ends. When the handle rod moves towards the other end of it, the handle rod pulls the other 3 drive rods and the 4 flexible members 42 towards the other end of it.

[0045] As a preferred embodiment, the end of the drive rod 31 is directly connected to one of the connection heads 43 of the corresponding corner deflector 40; in practical applications, the size of the drive rod 31 is appropriate so that the flexible member 42 of the corner deflector 40 remains in a taut state, thereby ensuring the working accuracy of the drive system 30. Preferably, a tightening module is also installed on the annular drive system 30 to keep the flexible member 42 in a taut state; such as Figures 17 to 19As shown, the tightening module includes a first tightening block 331, a second tightening block 332, and an adjustment screw 333. The first tightening block 331 is provided with a slide rail 3311, and the second tightening block 332 is provided with a chute adapted to the slide rail 3311. A pushing space 3312 is provided between the first tightening block 331 and the second tightening block 332. The adjustment screw 333 is installed in the pushing space 3312, and an internal thread adapted to the adjustment screw 333 is provided in the pushing space 3312. By turning the adjustment screw 333, the first tightening block 331 and the second tightening block 332 can move towards or away from each other. It can be added that one end of the flexible component 42 connecting the first tightening block 331 to the corner adapter 40 can be the first tightening block 331, and one end of the transmission rod 31 connected to the second tightening block 332 can be the second tightening block 332; alternatively, one of the transmission rods 31 of the annular transmission system 30 can be truncated, and then the tightening module can be installed at the truncated position for corresponding connection to ensure the tension of the annular system 30. Of course, the tension state of the annular system 30 can also be further ensured through other structures.

[0046] Preferably, the annular transmission system 30 further includes a side extrusion module, a support module, a limit module, a lateral locking module, etc. The specific structure can be seen below.

[0047] Preferably, a transmission slider is installed on the transmission rod 31, and the transmission slider has an installation through groove for the transmission rod 31 to pass through the transmission slider. It can be added that the transmission slider includes, but is not limited to, the side shift lock block 122, the auxiliary slider 61, the drive lock block 154, etc. described below.

[0048] In actual application, the annular transmission system 30 is installed in the window sash 50. The window sash 50 is usually formed by installing multiple aluminum alloy profiles, and the glass is installed in the rectangular area formed by the profiles of the window sash 50. A transmission groove 51 (also called a C-shaped groove) for installing the transmission rod 31 and other hardware is also provided in the profiles of the window sash 50. The annular transmission system 30 is installed in the transmission groove 51. Four of the aforementioned corner adapters 40 are arranged corresponding to the four corners of the window sash 50, and four of the aforementioned transmission rods 31 are arranged corresponding to the four sides of the window sash 50. The transmission rod 31 can only move along the extension direction of the corresponding side in the transmission groove 51.

[0049] Further, the aforementioned side extrusion module, support module, and limit module are arranged on the transmission rod 31 on the lower side of the window sash 50 (annular transmission system 30). An auxiliary module is also arranged on the transmission rod 31 on the upper side of the annular transmission system 30. The auxiliary module is used to further improve the smoothness of the side shift of the window sash 50; such as Figures 14 to 16As shown, the auxiliary module includes an auxiliary slider 61, and the auxiliary slider 61 is provided with a third guide groove, and the third guide groove has an auxiliary locking point 62, and the auxiliary locking point 62 is located in the third guide groove; it should be noted that the auxiliary module and the driving principle are roughly the same as the lateral locking module (also having a corresponding fixed seat 153), which will not be repeated here. The difference is that: the upper end of the auxiliary locking point 62 has a laterally arranged roller 621, and the window frame 20 has a guide groove 22 adapted to the roller 621; at the same time, when shifting sideways, the auxiliary locking point 62 is equivalent to the window frame 20 not moving forward and backward, while the auxiliary slider 61 (and the window sash 50) installed on the transmission rod moves forward and backward.

[0050] Specifically, the angler 40 further includes a base 41 and connectors 43 located at both ends of a flexible component 42. The base 41 has a through channel 411 for the flexible component 42 to pass through, and at least one end of the flexible component 42 is exposed outside the base 41. Specifically, the through channel 411 can be arranged in the middle of the base 41, that is, the through channel 411 can be a "口"-shaped through hole, or a non-closed groove arranged on the upper surface or lower surface of the base 41, that is, the through channel 411 can be a through groove approximately in the shape of "凵" located on the upper surface of the base 41, or a through groove approximately in the shape of "冂" located on the lower surface of the base 41; of course, the through channel 411 can also be a combination of two or more of the above different forms of through channels 411, that is, the through channel 411 can include a closed "口"-shaped through hole and a "冂"-shaped through groove at the same time.

[0051] The base 41 is "L"-shaped, and includes a first base 412 and a second base 413 that are perpendicular to each other. The base 41 is usually installed at the corner of the window sash 50; preferably, the base 41 is extended with a mounting buckle 414, and the mounting buckle 414 is used to buckle and install the base 41 in the transmission groove 51 (C-shaped groove) of the window sash 50. Preferably, the inner sides of the first base 412 and the second base 413 are extended with the mounting buckle 414 to ensure the stability of the installation. The mounting buckle 414 is preferably integrally formed on the base 41.

[0052] The flexible component 42 is usually a flexible belt or a flexible belt, such as a hardware belt such as a steel belt or an aluminum belt. The flexible component 42 can also be an accessory such as a rope, as long as the two ends of the flexible component 42 can be pulled freely and can move back and forth in the curved passage 411.

[0053] Preferably, the connector 43 has a fastening post 431, and the flexible member 42 has a fastening hole adapted to the fastening post 431; the connector 43 is further provided with a connection groove 432 for connecting the transmission rod 31. The connection groove 432 is in a "concave" shape. Specifically, the connection groove 432 includes two parallel first vertical grooves and a horizontal groove connecting the two first vertical grooves. A connection hole extends downward from the upper surface of the connector 43, and the connection hole communicates with the horizontal groove. The connection hole can be a threaded hole. The transmission rod 31 is usually made of aluminum, with relatively weak stiffness. During installation, a fastening screw 433 is inserted into the connection hole. Since the end of the fastening screw 433 is a tip, it can directly penetrate downward from the connection hole into the transmission rod 31, thus achieving a firm connection and omitting the process of pre-drilling (screw holes) in the transmission rod 31, improving production efficiency.

[0054] Generally, a pulley frame 10 is provided below the window sash 50. One side of the pulley frame 10 is provided with a pulley 11 or a track 21 adapted to the pulley 11. Among them, the side extrusion module is installed on the pulley frame 10. The side extrusion module includes a side shift locking point 121 and a side shift locking block 122. The side shift locking block 122 is provided with a first guiding groove 1221, and the first guiding groove 1221 extends obliquely along the length direction (i.e., the left-right direction) of the pulley frame 10. The side shift locking point 121 is located in the first guiding groove 1221. Through the cooperation of the first guiding groove 1221 and the side shift locking point 121, the side shift locking block 122 and the side shift locking point 121 can move relatively forward and backward. In actual application, the pulley frame 10 is usually installed on the lower side of the window sash 50 to assist the left-right translation of the window sash 50. One of the side shift locking point 121 and the side shift locking block 122 is used for installation and connection on the pulley frame 10, and the other is used for installation and connection on the window sash 50.

[0055] In actual application, it further includes a window frame body 20 for installing the window sash 50. For comparison Figure 7 and Figure 8 , when the track 21 is installed below the pulley frame 10, the window frame body 20 is provided with a corresponding pulley 11. This embodiment mainly takes the case where the pulley 11 is installed below the pulley frame 10 and the corresponding track 21 is provided on the window frame body 20 for detailed description.

[0056] Refer to Figure 5, the first guiding groove 1221 is generally inclined and curved in the left-right direction, rather than parallel to the length direction of the pulley 11 bracket 10, so as to ensure the pushing effect of the inner wall of the first guiding groove 1221 on the side shift locking point 121, so that the side shift locking point 121 can move forward and backward relative to the side shift locking block 122 in the first guiding groove 1221, realizing the extrusion of the window sash 50 against the window frame body 20. In this embodiment, the side shift locking point 121 is fixedly installed on the pulley bracket 10, and the side shift locking block 122 is used for fixedly installing on the window sash 50. In actual application, the window sash 50 is provided with a transmission system 30 for driving the movement of the side shift locking block 122 (the specific structure of the transmission system 30 can be referred to below). The transmission system 30 has a transmission rod 31, and the transmission rod 31 is drivingly connected to the side shift locking block 122 (preferably, the side shift locking block 122 has an installation through groove, and the transmission rod 31 passes through the installation through groove and is fixed to the transmission rod 31 by a connecting screw), and the transmission system 30 further includes a handle 32 (and a corresponding handle transmission box). The handle 32 is linked to the transmission rod 31, and the movement of the side shift locking block 122 is driven by the action of the handle 32. Further, the side shift locking point 121 moves in the first guiding groove 1221 of the side shift locking block 122. Preferably, one end of the first guiding groove 1221 has a first opening, which is convenient for the assembly of the side shift locking block 122 and the side shift locking point 121.

[0057] Further, the support module is used to improve the smoothness of the side shift of the window sash 50; specifically: the support module may include a track needle 131 and a sliding plate 132. One of the track needle 131 and the sliding plate 132 is used for installing on the window sash 50, and the other is used for installing on the pulley bracket 10, and the sliding plate 132 can move back and forth on the track needle 131. In this embodiment, the track needle 131 is installed in the pulley bracket 10, and the sliding plate 132 is fixedly installed on the window sash 50. The arrangement direction of the track needle 131 is the same as the length direction of the pulley bracket 10 (i.e., arranged in the left-right direction). The track needle 131 is cylindrical or tubular, and the track needle 131 is rotatably (self-rotating) installed on the pulley bracket 10 around its central axis. Specifically, the pulley bracket 10 is provided with a track needle 131 groove adapted to the track needle 131. Preferably, there are 2 track needles 131, and the 2 track needles 131 are arranged at intervals in the front-rear direction, so as to support the front side and the rear side of the sliding plate 132, improving the stability and smoothness of the side shift movement.

[0058] In other embodiments, the support module may also include a guide post and a catheter sleeved around the guide post. One of the guide post and the catheter is installed on the window sash 50, and the other is installed on the pulley 11 bracket 10. Through the relative movement of the guide post and the catheter, the smoothness of the front-back movement of the window sash 50 is improved.

[0059] Further, the limiting module includes a limiting slider 141 and a limiting locking point 142. One of the limiting slider 141 and the limiting locking point 142 is used to be installed on the window sash 50, and the other is used to be installed on the pulley 11 bracket 10. The limiting slider 141 is provided with a limiting sliding groove adapted to the limiting locking point 142; the limiting sliding groove extends in the front-rear direction. In this embodiment, the limiting locking point 142 is installed on the pulley bracket 10, and the limiting slider 141 is installed on the window sash 50. Preferably, the front end of the limiting sliding groove is a second opening, so as to facilitate the assembly of the limiting locking point 142; the rear end of the limiting sliding groove is closed (forming a limiting end / closed end).

[0060] It can be supplemented that: in this embodiment, the pulley bracket 10 is arranged on the lower side of the window sash 50. In actual application, the quantity and positions of the pulleys 11, the side extrusion module, the support module, the limiting module, etc. can be reasonably set according to the load-bearing capacity of the pulley bracket 10. In this embodiment, there are 2 pulleys 11, 2 side extrusion modules, and 2 support modules; there is 1 limiting module, and 1 limiting module is arranged between 2

[0061] Further, the pulley bracket 10 is preferably an "I"-shaped aluminum profile. The pulley bracket 10 has parallel lower side plates 101 and upper side plates 102, and the lower side plates 101 and the upper side plates 102 are connected by vertical vertical side plates 103. Flanges extend downward from the front side and the rear side of the lower side plate 101. The upper side plate 102 is provided with a lock point groove 1021 for installing the side shift locking point 121 (the aforementioned limiting locking point 142 is also fixedly installed in the lock point groove 1021). There are 2 track needle grooves, and the 2 track needle grooves 1022 are respectively located on the front side and the rear side of the lock point groove 1021; thus, it has many advantages such as reasonable structure, light overall weight, and simple manufacturing process.

[0062] Further refer to Figure 9 and Figure 10, the lateral locking module includes a lateral locking point 151 and a lateral locking seat 152. The lateral locking point 151 (also called a locking pin) is usually installed on the window sash 50, and the lateral locking seat 152 is usually installed on the window frame body 20. Specifically, a fixed seat 153 is fixedly installed on the window sash 50, the lateral locking point 151 is movably installed back and forth on the fixed seat 153, an avoidance channel is provided inside the fixed seat 153, the transmission rod 31 of the transmission system 30 passes through the avoidance channel, and a driving slider 154 is installed on the transmission rod 31 corresponding to the avoidance channel. The driving slider 154 is provided with a second guiding groove 1541, and the lateral locking point 151 has a guiding post 1511 adapted to the second guiding groove 1541. The guiding post 1511 is located in the second guiding groove 1541, and the second guiding groove 1541 extends obliquely (not linearly), so as to push the guiding post 1511 (and the lateral locking point 151) to move back and forth (extend or retract). When the window sash 50 is in a side-squeezing state, the lateral locking point 151 is located in the lateral locking seat 152 to achieve locking.

[0063] When corresponding actions of the operating handle 32 are performed, the side-shifting lock block 122 installed on the transmission rod 31 moves laterally (backward) relative to the sliding 1 frame 10 under the action of the side-shifting locking point 121 (the side-shifting locking point 121 is fixedly installed on the pulley 11 frame 10), so as to achieve side-squeezing of the window frame body 20. At the same time, during the lateral movement process, the aforementioned sliding plate 132 also rolls on the track needle 131, so as to improve the smoothness of side-shifting. And, after the lateral movement of the side-shifting lock block 122 (window sash 50) is in place, the limit locking point 142 is located at the limit end of the limit sliding groove. As Figure 6 shown, it is a guiding schematic diagram of the side-shifting principle (from top to bottom in sequence: initial installation state, window sash 50 opening state, window sash 50 locking state). When the transmission member 31 drives the side-shifting lock block to move leftward, the entire window sash 50 moves backward.

[0064] The design focus of the present utility model is that it mainly designs an annular transmission system. By pulling the two ends of the transmission device, it is more labor-saving and the transmission is smoother. And based on the design of the entire annular transmission system, the size of the transmission rod can be made smaller. Furthermore, without truncating the transmission rod of this application, the installation can be completed by passing the transmission rod through the hardware fittings (such as the transmission slider), and the installation of the entire door leaf system structure is also more convenient.

[0065] Secondly, a plurality of modules are correspondingly arranged on the transmission system of the present utility model, further improving the function of the transmission system, enhancing the practicability, better meeting the needs of modern consumers, and each module also has many advantages such as ingenious structure and easy implementation.

[0066] The above are only the preferred embodiments of the present utility model, and do not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
