Description

Technical Field

[0001] The utility model relates to the technical field of hardware, in particular to a modular transmission component for doors and windows. Background Art

[0002] The transmission component of doors and windows is related to the locking and airtightness of window sashes. For the transmission of some doors or tall windows, long transmission rods are required. However, long transmission rods are often not conducive to transportation. Slender transmission rods are extremely easy to bend, deform, and break. A bent transmission rod cannot be inserted into the transmission slot of the sash, and a broken transmission rod cannot be used at all. When doors and windows are designed and simulated, they are theoretical dimensions. However, during actual installation, there are often errors between the actual dimensions and the designed dimensions, either more or less. When there are problems with the installation dimensions of the lock nails, the doors and windows cannot be locked or are not airtight (poor airtightness, leaking air and water). There is a shaking phenomenon in a large number of door and window transmission components, bringing a very poor experience to users. In view of the above problems, a set of modular transmission components is designed. The length of each module is within a reasonable transportation range. No matter how long the transmission component is required, it can be spliced. The publication number is CN110242159A, which provides a quick-installation connector, a transmission rod, a connection component, and a door and window structure. Among them, the connection component includes a quick-installation connector and a transmission rod. The transmission rod is connected to the adjustment section of the quick-installation connector through a chute. Among them, the connection position of the adjustment section or the chute can be adjusted within its length range. The beneficial effect of the present invention is that the adjustment section of the quick-installation connector is connected to the transmission rod. Since the connection position of the transmission rod connecting the adjustment section or the connection position of the adjustment section connecting the transmission rod is adjustable, when there is an error in the length of the transmission rod, the influence of the error can be solved by adjusting the connection position of the transmission rod or the connection position of the adjustment section, without re-cutting the transmission rod. However, the transmission rod is integrally formed and is prone to deviation during actual installation, making it difficult to adapt to the installation of doors and windows in different scenarios. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a practical and reliable modular transmission component for doors and windows.

[0004] To achieve the above purpose, the solution provided by the present invention is: a modular transmission component for doors and windows, including a transmission rod and at least two lock nail components. The front and rear ends of the transmission rod are respectively connected to the lock nail components by buckling. When the number of the lock nail components is at least three, an adapter rod is detachably connected between two adjacent lock nail components.

[0005] The beneficial effects of the present utility model are as follows: The transmission component modularizes the traditional transmission rod. The component adopts a splicing design. By setting the transmission rod, a plurality of locking pin components, and the connecting rod, under normal length, the transmission rod can be snap-connected to the two locking pin components. When a longer length is required, the connecting rod is connected to the locking pin components until the set length is spliced. The overall operation is simple, and the overall structure is practical and reliable. In this way, the problems of bending deformation and transportation of long transmission rods are solved. Traditional long transmission rods are often not conducive to transportation. The slender transmission rods are extremely prone to bending deformation and fracture. The bent transmission rod cannot be inserted into the transmission slot of the fan, and the fractured transmission rod cannot be used at all. Moreover, the modular splicing design of the transmission rod can adapt to the existing door and window transmissions in the market, and any length of transmission component can be spliced.

[0035] In this embodiment, a plurality of first mounting grooves 14 are respectively formed on the left and right side walls of the transmission rod 1. First damping strips 15 are commonly connected to the front and rear inner side walls of the first mounting grooves 14. The first damping strips 15 protrude from the first mounting grooves 14. The first damping strips 15 are in an arc structure and protrude along the obliquely outer lower side.

[0036] In this embodiment, a plurality of second mounting grooves 22 are respectively formed in the left and right side walls of the connecting block 21.

[0037] In this embodiment, the first damping strip 15 and the second damping strip 23 are respectively made of rubber and plastic materials.

[0038] In this embodiment, a third mounting hole 26 is formed in the middle of the connecting block 21. A second locking nut 25 is arranged in the third mounting hole 26. The locking screw 24 enters the third mounting hole 26 and is connected with the second locking nut 25. A fixing nut 27 is arranged on the top surface of the connecting block 21. The fixing nut 27 is located directly above the third mounting hole 26. The locking screw 24 is sequentially connected with the fixing nut 27 and the second locking nut 25.

[0039] In this embodiment, the first connecting boss 111, the first connecting groove 213, the second connecting boss 214, and the second connecting groove 311 all have a fishbone-like structure. The splicing mode of this embodiment adopts a concave-convex structure and is connected by a fishbone interlocking structure, so that the transmission rod 1 and the connecting block 21, and the connecting block 21 and the connecting rod 3 are firmly buckled.

[0040] This embodiment adopts a modular design. Under normal conditions, this embodiment is composed of a transmission rod and a locking nail assembly. Among them, the transmission rod 1 and the locking nail assembly are each independent modules, and are assembled into the required length by assembling. Among them, the first docking boss 211 of a connecting block 21 is inserted into the first docking groove 11 at the front end of the transmission rod 1, and the first connecting groove 213 of the first docking boss 211 is buckled downward and connected to the first connecting boss 111 in the first docking groove 11. Then, the first docking boss 211 of a connecting block 21 is inserted into the first docking groove 11 at the rear end of the transmission rod 1, and the first connecting groove 213 of the first docking boss 211 is buckled downward and connected to the first connecting boss 111 in the first docking groove 11. In this way, the two connecting blocks 21 are respectively connected to the transmission rod 1. Then, the two first locking nuts 121 are respectively installed in the two first mounting holes 12. Finally, the second locking nut 25 is installed in the third mounting hole 26, the fixing nut 27 is installed on the third mounting hole 26, and the locking screw 24 is screwed in, so that the locking screw 24 is sequentially connected with the fixing nut 27 and the second locking nut 25, and the assembly of the transmission component of this embodiment is completed.

[0041] If this embodiment needs to be longer, a plurality of connecting rods 3 are matched and connected. According to the actual length, a set number of locking nail assemblies and a set number of connecting rods 3 are selected, such as Figure 5 and Figure 6As shown in the figure, specifically, the second docking boss 31 of the connecting rod 3 is inserted into the second docking groove 212 of the connecting block 21, and the third connecting groove 311 of the second docking boss 31 is buckled downward to connect the second connecting boss 214 in the second docking groove 212. Also, the first docking boss 211 of the connecting block 21 is inserted into the third docking groove 32 of the connecting rod 3, and the first connecting groove 211 of the first docking boss 211 is buckled downward to connect the first connecting boss 111 in the third docking groove 32, so as to realize the snap connection of the connecting rod 3 and the connecting block 21 until it is spliced into a set length. This modular form is convenient for packaging and transportation, making each component not bend or break. It can be spliced according to the required transmission length of the doors and windows, and is convenient for replacement and maintenance.

[0042] The locking screw 24 of this embodiment makes up for the fitting overlap amount and can prevent the window sash from not closing tightly. Specifically, by rotating the locking screw 24, the locking screw 24 can be retracted or extended into the third mounting hole 26, realizing the elongation or shortening of the locking screw 24, and better matching with the connecting block 24, so that the airtightness meets the requirements when the doors and windows are closed, without air leakage or water leakage. To ensure that the locking screw 24 does not loosen during use, a fixing nut 27 is used to reinforce the locking screw 24 to prevent loosening and make the connecting block 3 and the locking screw 24 fit tightly.

[0043] After this embodiment is installed in the transmission groove 41 of the door and window profile 4, since the first damping strip 15 protrudes along the oblique outer lower side and the second damping strip 23 protrudes along the oblique outer lower side, the multiple first damping strips 15 and the multiple second damping strips 23 plastically deform in the transmission groove 41. Thus, the multiple first damping strips 15 fill the gap between the transmission groove 41 and the transmission rod 1, and the multiple second damping strips 23 fill the gap between the transmission groove 41 and the connecting block 21, effectively preventing the transmission rod 1 and the connecting block 21 from shaking. During installation, due to the effect of damping, the transmission rod 1 and the connecting block 21 are not easy to slide in the transmission groove 41. When installing, the transmission rod 1 and the connecting block 21 components of this embodiment can be arbitrarily positioned, which is convenient for installing other matching parts.

[0044] The above-described embodiments are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art can make more possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention.
