Description

Technical Field

[0001] The invention relates to the technical field of transmission rods, in particular to a quick-install transmission rod. Background Art

[0002] Conventional transmission rods on the market need to be installed through grooves, and all installation holes must be punched out before they can be installed with accessories. In reality, the manufacturing process of many doors and windows does not meet the standards, and the actual size does not match the theoretical size. At this time, the prepared transmission rod does not match the accessories, and then the entire set of accessories needs to be removed, and the manufacturer needs to make a new transmission rod. This repeated assembly and disassembly of the transmission rod wastes both time and materials. Summary of the invention

[0003] The object of the present invention is to provide a quick-install transmission rod to solve the problems raised in the above background technology.

[0004] In view of the above problems, the technical solution proposed by the present invention is: A quick-install transmission rod comprises a transmission rod, a side surface of the transmission rod is provided with an opening, a pair of side surfaces of the opening are inclined surfaces, a top surface of the transmission rod is provided with a pair of limiting grooves, a pair of the limiting grooves are set as a clamped position on a side close to each other, a portion of the top surface of the transmission rod between the pair of limiting grooves is set as a screw-through position, one side of the transmission rod is higher than the other side, a pair of fulcrums are provided on the shorter side of the transmission rod, and a limiting surface is provided on the taller side of the transmission rod; a window frame, a first slide groove and a second slide groove are provided on the top surface of the window frame, and the second slide groove is located above the first slide groove and is connected to the first slide groove, the transmission rod slides in the first slide groove and the second slide groove, a pair of the fulcrums abut against the side surfaces of the first slide groove, and the limiting surface abuts against the side surfaces of the second slide groove, and when installing the transmission rod, it does not need to be installed through the groove, and direct insertion-type left-side installation or right-side installation can be achieved. Figure 3 When it is repaired or replaced, it can also be disassembled on the left or right side. The fulcrum of the transmission rod is tangent to the second slide slot. When the transmission rod is flipped, the transmission rod uses the installation gap with the first slide slot, that is, the transmission rod can be installed. After the transmission rod is installed in the first slide slot and the second slide slot, the transmission rod is placed straight in them, as shown in FIG. Figure 4 The limiting surface is used to be stuck in the first slide groove and the second slide groove. When in use, the transmission rod is in the first slide groove and the second slide groove, and the two interact with each other to prevent the transmission rod from shaking.

[0005] Furthermore, a pair of grooves is provided on the bottom surface of the transmission rod, and the pair of grooves divides the bottom surface of the transmission rod into three sections, and all three sections are contact points. When the transmission rod slides in the first slide groove and the second slide groove, in order to avoid friction deformation caused by the contact surface, the surface-to-surface contact is changed to surface-to-line contact.

[0006] Furthermore, the bottom surface of the transmission rod is set as an avoidance arc near the limiting surface. When the transmission rod is installed on the door and window profile, the avoidance arc allows the transmission rod to be smoothly installed in the groove.

[0007] Further, the hardware accessories are located in the first slide slot, the hardware accessories have a set screw, and the set screw passes through the screwing position and abuts against the inclined surface. Both sides of the screwing position are clamped positions. The hardware accessories are connected with a fixed block on the end face close to the transmission rod, the fixed block slides in the limit groove, the set screw and the fixed block are threaded and connected, and the top surface of the fixed block is provided with an observation hole. The transmission rod does not need to be punched for installation, and the window sash with size problems can be taken into account because the transmission rod is adjustable. When the transmission rod and the hardware accessories are installed, the set screws can be tightened in the debugging stage. During debugging, if the operation is not smooth, or the reset of each accessory is not correct, loosen the set screw with a tool, move the accessory horizontally, and check the position of the transmission rod through the observation hole during the movement to ensure that the amount of movement is known. After moving, tighten the set screw to clamp the clamped position of the transmission rod with the hardware accessories, and then operate the opening and closing. After multiple attempts at debugging, the position of the hardware accessories and the transmission rod can be confirmed. After debugging and opening and closing smoothly, use a tool to tighten the set screw until it penetrates the transmission rod. This ensures that the accessories and the transmission rod will not loosen during daily use. When the set screw penetrates the transmission rod, the designed bevel will prevent the set screw from being tightened further to avoid failure.

[0008] Furthermore, the transmission rod is made of metal.

[0009] Compared with the prior art, the invention has the following beneficial effects: the quick-release transmission rod does not need to be installed through a groove, and can be directly inserted into the left side or the right side for installation; the connection with the accessory is a clamping type, and there is no need to drill a hole on the transmission rod; during the installation and debugging phase, the set screw is loosened to move the position of the accessory, and there is an observation hole at the connection of the accessory, so that the position of the transmission rod in the accessory can be checked, which is convenient for debugging, and the screw is tightened after smooth operation or complete reset; after debugging is completed, the set screw is tightened with a tool until the transmission rod is screwed through, which can ensure that the accessory and the transmission rod will not loosen during daily use; the inclined surface on the transmission rod can prevent the screw from being over-tightened, thereby avoiding damage to the transmission rod or thread slippage.

DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1 - Figure 8 The present invention provides a technical solution: a quick-install transmission rod, comprising: Preparation before installation: prepare the quick-install transmission rod 100, window frame 200 and hardware accessories 300 of the present invention. Check the transmission rod 100 to ensure that its side opening 1002, inclined surface 1003, limit groove 1010, screw-through position 1001, fulcrum 1006, limit surface 1008, groove 1004, avoidance arc 1007 and other structures are intact. At the same time, confirm that the fixing block 3003, set screw 3004 and observation hole 3002 of the hardware accessories 300 are in good condition. Check the first slide groove 2001 and the second slide groove on the top surface of the window frame 200 to ensure that there is no debris in the slide groove and the surface is smooth to ensure that the transmission rod can slide smoothly.

[0014] Installation process: According to the installation requirements of the window frame, choose the left-side installation or right-side installation method. Taking the left-side installation as an example, align the pair of fulcrums 100 on the shorter side of the transmission rod 100 with the side of the first slide groove 2001 on the top surface of the window frame 200, and slowly insert the transmission rod into the first slide groove 2001. Since the relative position of the limiting surface 1008 of the transmission rod 100 and the second slide groove is reasonably designed, during the insertion process of the transmission rod, the limiting surface 1008 naturally enters the second slide groove, and the fulcrum 1006 abuts against the side of the first slide groove 2001. During the insertion process, the groove 1004 on the bottom surface of the transmission rod 100 changes the contact mode from surface contact to line contact, reducing friction and facilitating the smooth installation of the transmission rod. The avoidance arc 1007 of the transmission rod 100 close to the limiting surface 1008 avoids interference with the notch of the window frame, ensuring smooth installation of the transmission rod.

[0015] Connection and debugging with hardware accessories: Place the hardware accessory 300 into the first slide groove 2001, align the fixed block 3003 with the limit groove 1010 on the top surface of the transmission rod 100 and slide it into it. Pass the set screw 3004 through the fixed block 3003, align it with the transmission rod 100 and screw it through the position 1001. During the debugging stage, first gently tighten the set screw 3004 to make a preliminary connection between the hardware accessory 300 and the transmission rod 100. If it is found that the opening or closing is not smooth during the operation of the door and window, or the reset of each accessory is not normal, use a screwdriver or other tools to loosen the set screw 3004 and move the hardware accessory 300 horizontally. Observe the position change of the transmission rod 100 through the observation hole 3002 on the top surface of the fixed block 3003 to ensure accurate adjustment of the hardware accessory position. Try debugging several times until the door and window open and close smoothly and the accessories are reset normally.

[0016] Tightening and daily use: After debugging is completed, use a tool to further tighten the set screw 3004. As the set screw is gradually screwed in, it passes through the screw-through position 1001 and abuts against the inclined surface 1003. When the set screw 3004 is about to screw through the transmission rod 100, the inclined surface 1003 blocks the set screw from being screwed in further, preventing the set screw from being screwed in too far and causing the transmission rod to be damaged or stripped. At this time, the clamping position 1009 of the transmission rod 100 is tightly clamped with the hardware accessory 300, ensuring that the accessory and the transmission rod will not loosen during daily use.
