[0038] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0039] The quick-install transmission rod of the utility model is used to be installed in the C-shaped groove of the door and window frame, and is combined with a transmission device, a handle, etc. to realize the locking of the door and window. Figure 2As shown, the C-shaped groove 30 of the door and window frame includes a groove, a bottom wall 31, two opposite groove walls 32 and two opposite groove walls 33, wherein the two groove walls 32 are respectively connected to the bottom wall 31, and the two groove walls 33 are respectively located on both sides of the groove, that is, the C-shaped groove 30 is located in the semi-enclosed area of the bottom wall 31, the two groove walls 32 and the two groove walls 33, and the spacing W11 of the two groove walls 33 is smaller than the spacing W12 of the two groove walls 32. The bottom wall 31, the two groove walls 32 and the two groove walls 33 can be planar, respectively. In practical applications, one or more of the bottom wall 31, the two groove walls 32 and the two groove walls 33 can be curved, and in particular, the two groove walls 33 can also be straight (i.e., the height of the groove walls 33 is extremely small). The C-shaped groove is a conventional structure in the art and will not be described in detail here.
[0040] like Figure 1 , which is a schematic diagram of a quick-release transmission rod provided by an embodiment of the utility model. The quick-release transmission rod of this embodiment includes a metal rod 10 and a plurality of blocks 20. The number of blocks 20 can be set according to the length of the metal rod 10. The longer the metal rod 10 is, the more blocks 20 there are. Similar to the existing transmission rod, the metal rod 10 can be made of aluminum alloy, stainless steel and other materials and is in a flat strip shape. It can have a plurality of locking points (the locking points can cooperate with the locking structure on the door frame or window frame to achieve door and window locking). The metal rod 10 can be installed in the C-shaped groove 30 with the cooperation of the blocks 20, and slide in the C-shaped groove 30 along the length direction X under the drive of the transmission, so that the locking points are engaged with the corresponding locking structure of the door frame or window frame.
[0041] Combination Figure 3 , Figure 4As shown, the metal rod 10 includes a first main body portion 11 and a strip-shaped protrusion portion 12, wherein the height of the first main body portion 11 (i.e., the dimension perpendicular to the XY plane direction) is adapted to the height of the groove wall 32 (for example, the height of the first main body portion 11 is slightly smaller than the height of the groove wall 32), and the strip-shaped protrusion portion 12 is located on the upper surface of the first main body portion 11 and is arranged along the length direction of the metal rod 10. It can be understood that the width of the strip-shaped protrusion portion 12 is smaller than the width of the first main body portion 11, and the two side edges of the strip-shaped protrusion portion 12 are respectively located on the inner sides of the two side edges of the first main body portion 11. The above-mentioned first main body portion 11 includes a first vertical side wall 111 and a second vertical side wall 112 respectively perpendicular to the width direction Y, and accordingly, the strip-shaped protrusion portion 12 includes a third vertical side wall 121 and a fourth vertical side wall 122 respectively perpendicular to the width direction Y, wherein the first vertical side wall 111 is adjacent to the third vertical side wall 121 and has the same orientation, the second vertical side wall 112 is adjacent to the fourth vertical side wall 122 and has the same orientation, and the spacing W21 between the first vertical side wall 111 and the third vertical side wall 121 is greater than the spacing W22 between the second vertical side wall 112 and the fourth vertical side wall 122. The spacing W24 between the first vertical side wall 111 and the fourth vertical side wall 122 is greater than the width of the slot of the C-shaped slot 30 (i.e., the spacing W11 between the two slot walls 33), the spacing W25 between the third vertical side wall 121 and the fourth vertical side wall 122 is less than the width of the slot of the C-shaped slot 30, and the spacing W23 between the third vertical side wall 121 and the second vertical side wall 112 is less than the spacing W13 between one of the slot walls 33 of the C-shaped slot 30 and the opposite slot wall 32 (i.e., the slot wall with a longer distance). Specifically, the first vertical side wall 111 and the second vertical side wall 121 are not limited to planes, and may also be micro-arc surfaces, etc.
[0042] The block 20 can be made of non-metallic materials such as plastic and resin with relatively low hardness, so that it can be deformed to a certain extent by extrusion, etc. The block 20 is mounted on the metal rod 10, and each block 20 includes an elastic portion 22. When the metal rod 10 is mounted to the C-shaped groove 30, the elastic portion 22 of the block 20 pushes the metal rod 10 so that the fourth vertical side wall 122 abuts against one of the notch walls 33 of the C-shaped groove 30.
[0043] In this way, Figure 5As shown, when the metal rod 10 is installed in the C-shaped groove 30, the block 20 can be first fixed to the metal rod 10, and then one side of the first vertical side wall 111 of the first main body 11 is first installed into the C-shaped groove 30 through the notch of the C-shaped groove 30, until the third vertical side wall 121 of the strip-shaped protrusion 12 is in contact with the corresponding notch wall 33. Since the distance W23 between the third vertical side wall 121 and the second vertical side wall 112 is smaller than the distance W11 between the notch wall 33 of the C-shaped groove 30 and the opposite groove wall 32, The other side of the first main body 11 can also be inserted into the C-shaped groove 30 through the notch. After the lower surface of the first main body 11 is in contact with the bottom wall 31 of the C-shaped groove 30, the elastic portion 22 of the block 20 pushes the metal rod 10 along the width direction Y, so that the fourth vertical side wall 122 of the strip-shaped protrusion 12 is in contact with the notch wall of the C-shaped groove 30. Since the distance W24 between the first vertical side wall 111 and the fourth vertical side wall 122 is greater than the width of the notch of the C-shaped groove 30, the metal rod 10 cannot escape from the C-shaped groove 30. Figure 6 In particular, to facilitate the metal rod 10 to be inserted into the C-shaped groove 30 , the bottoms of the first vertical side wall 111 and the second vertical side wall 112 of the first main body portion 11 may have arc-shaped chamfers.
[0044] The above-mentioned quick-release transmission rod makes the distance between one of the second vertical side walls 121 on the metal rod 10 and the first vertical side wall 111 opposite thereto smaller than the distance between the slot wall 33 adjacent to the second vertical side wall 121 in the C-shaped slot 30 and the opposite slot wall 32, so that the metal rod 10 can be obliquely inserted into the C-shaped slot 30, and then the two clamping plate parts 21 of the clamping block 20 limit its movement in the width direction to prevent it from escaping from the C-shaped slot 30, which greatly facilitates the assembly and subsequent maintenance of the transmission rod.
[0045] like Figure 4 As shown, in one embodiment of the utility model, each block 20 includes a second main body 21, and the elastic part 22 is composed of an arc-shaped strip with two ends integrally connected (for example, integrally injection molded) to the outer edge of the second main body 21. In a natural state (i.e., when not subjected to pressure), the middle part of the elastic part 22 is away from the second main body 21; when subjected to pressure along the width direction, the elastic part 22 is compressed (i.e., the middle part of the elastic part 22 is close to the second main body 21, and a thrust is applied to the second main body 21. The above-mentioned elastic part 22 has a simple structure, and because it is integrally connected with the second main body 21, the production, processing and assembly are relatively simple.
[0046] like Figure 1 , Figure 3As shown, in one embodiment of the utility model, the elastic part 22 (i.e., the outer edge of the arc strip) of the clamping block 20 installed on the metal rod 10 protrudes from the first vertical side wall 111 in a natural state, and the distance between the outer edge of the elastic part 22 in a natural state and the fourth vertical side wall 122 is greater than the distance between one of the slot walls 33 of the C-shaped groove 30 and the opposite slot wall 32, and the distance between the outer edge of the elastic part 22 in a maximum compression state and the fourth vertical side wall 122 is less than the distance between one of the slot walls 33 of the C-shaped groove 30 and the opposite slot wall 32. Through the above structure, the metal rod 10 equipped with the clamping block 20 can be placed obliquely in the C-shaped groove 30, and the metal rod 10 will not fall out of the C-shaped groove 30 after being placed in the C-shaped groove 30.
[0047] like Figure 4 As shown, in one embodiment of the utility model, the block 20 can be fixed on the metal rod 10 in the following manner: a first assembly groove 13 is provided on the lower surface of the metal rod 10, and both sides of the first assembly groove 13 penetrate the upper surface of the metal rod 10; a second assembly groove 23 is provided on the upper surface of the second main body of the block, and the block 20 is assembled to the metal rod 10 in a manner that the second assembly groove 23 and the first assembly groove 13 are embedded, that is, the block 20 and the metal rod 10 are assembled together in a manner similar to mortise and tenon joints. Through the above structure, the block 20 can be assembled to the metal rod 10 very conveniently.
[0048] Furthermore, the edges of the block 20 mounted on the metal rod can be made to protrude from the edges of the metal rod 10, so that the metal rod 10 does not contact the inner wall of the C-shaped groove 30. Since the block 20 is made of non-metallic materials such as plastic and resin with relatively low hardness, this structure can also reduce the noise when the transmission rod slides in the C-shaped groove 30.
[0049] Of course, in practical applications, the block 20 may also be fixed on the metal rod 10 by other existing structures, which will not be described in detail here.
[0050] like Figure 7-10 As shown, in one embodiment of the present invention, the elastic part 22 of the clamping block 20 mounted on the metal rod 10 protrudes from the third vertical side wall 121 of the metal rod 10 in a natural state, and the distance between the outer edge of the elastic part 22 in a natural state and the fourth vertical side wall 122 is greater than the width of the notch of the C-shaped groove 30, and the distance between the outer edge of the elastic part 22 in a maximum compression state and the fourth vertical side wall 122 is less than or equal to the width of the notch of the C-shaped groove 30. The above structure also facilitates the metal rod 10 equipped with the clamping block 20 to be obliquely placed in the C-shaped groove 30, and the metal rod 10 will not fall out of the C-shaped groove 30 after being placed in the C-shaped groove 30.
[0051] like Figure 8As shown, in one embodiment of the utility model, the block 20 can be fixed on the metal rod 10 in the following manner: a strip-shaped through groove 16 is provided on the lower surface of the first main body 11 of the metal rod 10 (that is, the metal rod 10 is in an eccentric "J" shape), a first through hole 14 connected to the strip-shaped through groove 16 is provided on the third vertical side wall 121, and a clearance notch 15 is provided at a position corresponding to the first through hole 14 on the metal rod 10; on the block 20, the elastic part 22 protrudes from the upper surface of the second main body 21, and the block 20 also includes a protrusion 24 protruding from the upper surface of the second main body 21, and the block 20 is fixed on the metal rod 10 in a manner that the second main body 21 is embedded in the strip-shaped through groove 16, the elastic part 22 passes through the first through hole 14 and protrudes from the third vertical side wall 121, and the protrusion 24 is embedded in the clearance notch 15. The above structure makes the block 20 and the metal rod 10 relatively firmly combined.
[0052] In addition, the block 20 can also be fixed to the metal rod 10 in the following manner: a third assembly groove is set on the lower surface of the metal rod 10, and a second through hole connected to the third assembly groove is provided on the third vertical side wall 121; the block 20 is fixed to the metal rod 10 in such a manner that the second main body portion 21 is embedded in the third assembly groove, and the elastic portion 22 passes through the second through hole and protrudes from the third vertical side wall 121.
[0053] In one embodiment of the utility model, on the metal rod 10, the height of the strip-shaped protrusion 12 protruding from the first main body 11 is adapted to the height of the slot wall 33, so that when the metal rod 10 is installed in the C-shaped slot 30, the upper surface of the metal rod 10 is basically flush with the slot edge of the C-shaped slot 30.
[0054] The utility model also provides a door and window transmission assembly, including a transmission device and the quick-install transmission rod as described above, wherein the transmission device can adopt any existing structure, and the transmission device is connected to the metal rod in a transmission manner, thereby driving the metal rod to slide in the C-shaped groove of the door and window frame.
[0055] The utility model also provides a door and window structure, including a door and window frame and the door and window transmission assembly as described above, the door and window frame includes a C-shaped groove, and the metal rod of the door and window transmission assembly is installed in the C-shaped groove, the clamping block is fixed on the metal rod and pushes the metal rod through the elastic part, so that the fourth vertical side wall of the metal rod abuts against the corresponding notch wall of the C-shaped groove.
[0056] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
