Description

Technical Field

[0001] This utility model relates to the field of door and window hardware, and more specifically, to a transmission rod feeding adjustment structure and an inward opening and tilting window. Background Technology

[0002] Traditional transmission rod feeding adjustment mechanisms consist of a threaded fixed block on the main rod, which is then assembled with a movable block connected to the transmission rod using screws. During use, tightening the screws allows the movable block and fixed block to slide relative to each other within a certain range along the screw's axial direction, thus resolving dimensional errors in the transmission rod feeding.

[0003] Because the fixed and movable blocks need to be stacked together, their dimensions cannot be too thick, resulting in insufficient strength for high-impact destructive power. Furthermore, due to the limitation of the slot size, the screw specifications that can be used are too small, often leading to stripped screw threads or deformation of the drive groove of the nut. In addition, the above structure also has the problem of exposed screws. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] like Figure 1-3 The diagram shows a schematic of the transmission rod feeding adjustment structure provided in this embodiment of the present invention. This transmission rod feeding adjustment structure can be applied to door and window hardware and realizes the connection between the transmission rod (i.e., the aluminum rod assembled in the sash frame profile) 10 in the door and window hardware and other parts (such as corner pieces, transmission boxes, etc.). The transmission rod 10 has an assembly hole 12 (the assembly hole 12 is usually a round hole with a smooth inner wall). The transmission rod feeding adjustment structure of this embodiment includes a main rod 20 and a movable connecting assembly 30. The main rod 20 can be a corner piece, transmission box, etc. in door and window hardware. The movable connecting assembly 30 is assembled between the main rod 20 and the transmission rod 10 and can slide relative to the main rod 20 in a straight line direction (the length direction of the transmission rod 10) within a certain range.

[0039] The aforementioned main rod 20 can be made of sheet metal, aluminum alloy, or other metal materials. One end of the main rod 20 has a sliding groove 21, a strip-shaped hole 22, and a strip-shaped slot 23 respectively arranged along a first direction X, where X is the length direction of the transmission rod 10. The opening of the sliding groove 21 is located on the end face of the main rod 20 (i.e., the end face facing the transmission rod 10). The strip-shaped hole 22 extends from the top of the main rod 20 into the sliding groove 21, while the strip-shaped slot 23 extends from the sliding groove 21 to the bottom of the main rod 20. That is, the strip-shaped hole 22 is located above the sliding groove 21, and the strip-shaped slot 23 is located below the sliding groove 21, with both the strip-shaped hole 22 and the strip-shaped slot 23 communicating with the sliding groove 21. The opening of the strip-shaped slot 23 is also located on the end face of the main rod 20 (i.e., the end face facing the transmission rod 10). In practical applications, the end face of the main rod 20 (i.e. the end face facing the transmission rod 10) may not have an opening for the slot 23, that is, the slot 23 may be replaced by a slot hole.

[0040] The movable connection assembly 30 includes a columnar body 31, a clamping piece 32, and a screw 33. The cross-sectional shape of the columnar body 31 is the same as that of the mounting hole 12 on the transmission rod 10; for example, its cross-section can be circular. The diameter of the cross-section of the columnar body 31 is slightly smaller than the diameter of the mounting hole 12, so that the columnar body 31 can be easily inserted into the mounting hole 12 and connected to the transmission rod 10. The columnar body 31 also has an axially arranged threaded hole 311. The threaded hole 311 can be a through hole with internal threads that penetrates the columnar body 31 axially, or a blind hole with internal threads that opens on the top surface of the columnar body 31. The screw 33 is threaded into the threaded hole 311, and the radial dimension of the screw head of the screw 33 is greater than the width of the slotted hole 22, meaning that the screw 33 placed in the groove 21 cannot be dislodged from the slotted hole 22.

[0041] The clamping piece 32 is sheet-shaped and fixedly connected to the columnar body 31. After being connected to the columnar body 31, the clamping piece 32 is substantially perpendicular to the axial direction of the columnar body 31. For example, the clamping piece 32 can be vertically connected to the top of the columnar body 31. The dimension of the clamping piece 32 in at least one direction in the radial direction of the columnar body 31 is greater than the width of the strip groove 23 on the main body member 20, so that after the clamping piece 32 is placed in the sliding groove 21, the clamping piece 32 will not come out of the sliding groove 21 by rotating the columnar body 31.

[0042] The movable connecting assembly 30 is slidably assembled into the groove 21 of the main body rod 20, and the bottom of the columnar main body 31 passes through the strip groove 23 and is inserted into the assembly hole 12 of the transmission rod 10 below the main body rod 20. The screw head of the screw 33 is located below the strip hole 22, and by driving the screw 33 to rotate in the threaded hole 311, the screw head presses against the top wall of the groove 21, and the clamping piece 32 presses against the bottom wall of the groove 21, thereby locking and fixing the movable connecting assembly 30 in the groove 21.

[0043] When it is necessary to adjust the connection length between the transmission rod 10 and the main body rod 20, a tool can be passed through the slot 22 to tighten the screw 33, causing it to descend (i.e., move along the second direction Y) until there is a gap between it and the top wall of the slide groove 21. Figure 5 As shown, the transmission rod 10 can be moved along the first direction X at this time; after the transmission rod 10 is moved into place, the screw 33 is tightened again through the tool passing through the strip hole 22 to make it rise, and the screw head presses against the top wall of the slide groove 21. At the same time, the columnar body 31 drives the clamping piece 32 to press down on the bottom wall of the slide groove 21 under the reaction force of the screw 33, thereby locking the movable connecting assembly 30 in the slide groove 21, that is, the movable connecting assembly 30 is locked with the main body rod 20, as shown. Figure 6 As shown.

[0044] The aforementioned transmission rod feeding adjustment structure secures the movable connection assembly 30 by installing the sliding connection component 30 within the groove 21 of the main rod 20. The screw head of the screw 33 and the clamping piece 32 within the sliding connection component 30 abut against the top and bottom walls of the groove 21, respectively. The screw 33 has a relatively large axial length within the threaded hole 311, reducing the risk of stripping. Furthermore, since the sliding connection component 30 is essentially enclosed by the main rod 20, its structural strength is relatively high. In addition, this structure prevents the screw 33 from being exposed, improving product consistency.

[0045] In one embodiment of this utility model, the width of the strip groove 23 on the main body 20 is greater than the width (diameter) of the screw head of the screw 33, and the dimension of the clamping piece 32 in at least one direction of the radial direction of the columnar body 31 is smaller than the width of the strip groove 23. For example, the clamping piece 32 can be a parallelogram or an ellipse. In this way, by adjusting the angle of the clamping piece 32 (i.e., the columnar body 31), the entire movable connecting assembly 30 can be placed into the slide groove 21 from below the main body 20 and through the strip groove 23. Then, by rotating the clamping piece 32 so that its larger radial dimension is perpendicular to the first direction X, the screw 33 can be rotated to lock and fix the movable connecting assembly 30.

[0046] Of course, in practical applications, the width of the strip groove 23 can be made only greater than the diameter of the columnar body 31, and the movable connecting component 30 can be inserted into the slide groove 21 from the end of the main body rod 20, but the operation is relatively inconvenient.

[0047] In one embodiment of this utility model, the above-mentioned transmission rod feeding adjustment structure further includes a fixing mold 40, which can be made of a polymer material with a certain hardness, such as engineering plastics. The fixing mold 40 includes two parallel clamping rods 41, and the two clamping rods 41 are inserted through the opening of the slide groove 21 between the screw head of the screw 33 and the clamping piece 32 in the slide groove 21, and clamp the screw from both sides of the screw 33 to prevent the screw 33 from loosening (i.e., the screw head moves towards the clamping piece 32), thereby improving the stability of the movable connecting assembly 30 in the locked state. Specifically, when the length needs to be adjusted, the clamping rods 41 can be removed from the slide groove 21, and after the adjustment is completed (after the movable connecting assembly 30 is locked), the clamping rods 41 can be inserted back into the slide groove 21.

[0048] In particular, such as Figure 4As shown, a first inclined surface 211 is formed between the top surface and the side surface of the groove 21 of the main rod 20. Correspondingly, each clamping rod 41 has a second inclined surface 411 corresponding to the first inclined surface 211 and a third inclined surface 412 corresponding to the lower conical surface of the screw head of the screw 33. When the clamping rods 41 are inserted into the groove 21, the second inclined surfaces 411 of the two clamping rods 41 are respectively in contact with the two first inclined surfaces 211 of the groove 21, and the third inclined surfaces 412 of the two clamping rods 41 are respectively in contact with the lower conical surface of the screw head of the screw 33. Through the above structure, the surface pressure between the clamping rods 41 and the screw 33 can be increased, thereby better preventing the screw 33 from loosening.

[0049] In one embodiment of this utility model, the fixed template 40 further includes a sealing plate 42, with two clamping rods 41 respectively vertically connected to the inner side of the sealing plate 42. The size of the sealing plate 42 is adapted to the size of the end faces of the openings of the sliding groove 21 and the strip groove 23 on the main body rod 20. When the clamping rods 41 are inserted into the sliding groove 21, the sealing plate 42 is in contact with the end face of the main body rod 20. Through the sealing plate 42, the two clamping rods 41 can be inserted into the sliding groove 21 simultaneously, and the surface uniformity of the product can be improved by sealing the opening of the sliding groove 21.

[0050] Furthermore, the inner surface of the aforementioned sealing plate 42 may also have a plug head 43, the size of which is adapted to the size of the opening of the slide groove 21 and the strip groove 23, and when the clamping rod 41 is inserted into the slide groove 21, the plug head 43 seals the opening of the slide groove 21 and the strip groove 23. The plug head 43 can improve the stability of the clamping rod 41 in the slide groove 21 and prevent it from coming out of the slide groove 21.

[0051] In one embodiment of this utility model, the main rod 20 has a clearance position 25 below the strip groove 23, and the cross-sectional dimensions of the clearance position 25 are adapted to the cross-sectional dimensions of the transmission rod 10. With this structure, the transmission rod 10 can be embedded into the clearance position 25 when connected to the main rod 20, improving product consistency.

[0052] In one embodiment of the present invention, one end of the main rod 20 includes a top plate, two side plates that are vertically connected to the two sides of the top plate, and two support plates that are vertically connected to the inner sides of the two side plates. The sliding groove 21 is located in the area enclosed by the top plate, the two side plates and the two support plates, the strip groove 23 is located between the two support plates, and the strip hole 22 is located on the top plate.

[0053] In addition, the transmission rod 10 includes two first wing plates 11 protruding from the sides, and the main rod 20 includes two second wing plates 24 protruding from the two side plates. When the transmission rod feeding adjustment structure is assembled to the fan frame profile, the first wing plates 11 and the second wing plates 24 are respectively embedded in the C-shaped groove of the fan frame profile.

[0054] This utility model also provides an inward-opening and inward-tilting door / window, including the transmission rod feeding adjustment structure as described above.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
