Description

Technical Field

[0001] This utility model belongs to the technical field of screw-type window openers, specifically a nut guide seat for a screw-type window opener. Background Technology

[0002] Screw-type window openers, as the core device for realizing automated window opening and closing, are widely used in construction, industry, smart home and other fields. They use a motor to drive the screw rod to rotate, and use a nut to convert the rotational motion into linear motion to push the window sash to open or close. The nut guide seat, as a key component of the screw-type window opener, is mainly used to guide the nut to make stable linear motion along the axis of the screw rod, while bearing radial load and preventing the nut from rotating synchronously with the screw rod. It plays a decisive role in the operating accuracy, stability and service life of the window opener.

[0003] However, the existing screw-type window opener nut guide seat still has many shortcomings: traditional guide seats are mostly integral structures, which are cumbersome and inefficient to assemble, and the entire nut guide seat needs to be replaced during maintenance, increasing the later maintenance cost; in dusty environments such as outdoors and industrial plants, dust and sand can easily penetrate and come into direct contact with the threaded rod, which not only accelerates the wear of transmission components, but also easily leads to the failure of lubricating grease and shortens the service life of the device.

[0004] Therefore, a nut guide seat for a screw-type window opener is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a nut guide seat for a screw-type window opener, which features a split design for easy disassembly and maintenance, reduced costs, an elastic liner and guide structure to improve operational stability and accuracy, and a dust scraper assembly to effectively prevent foreign objects, enhance environmental adaptability, and extend service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nut guide seat for a screw-type window opener, comprising a split seat body, a positioning groove formed on the inner wall of the split seat body, an elastic liner provided on the inner wall of the positioning groove, a nut provided on the inner side of the elastic liner, a threaded rod connected to the nut, dust scraping components connected to both the front and rear sides of the split seat body, and two symmetrically arranged fixing ears fixedly connected to the split seat body, each fixing ear having a guide hole, and a guide rod slidably fitting against the inner wall of the guide hole.

[0007] Preferably, the split-type base includes an upper base and a lower base arranged vertically, and the upper base and the lower base are fixed with corresponding side ears on their left and right sides, and the corresponding side ears are connected by fasteners.

[0008] Preferably, the fastener consists of a fixing bolt and a fixing nut, wherein the fixing bolt is threadedly connected to the fixing nut.

[0009] Preferably, the side ear has a through hole corresponding to the fixing bolt, and the bolt thread passes through the through hole to connect to the fixing nut.

[0010] Preferably, the dust scraping assembly includes a fixing ring, a dust scraping ring is connected to the inner side of the fixing ring, and a plurality of evenly distributed ear plates are fixedly connected to the outer side of the fixing ring. Connecting bolts are provided on the ear plates, and the connecting bolts are movably connected to the split-type base.

[0011] Preferably, the thickness of the dust scraper ring decreases from the outside to the inside, and the inner wall of the dust scraper ring slides against the threaded rod.

[0012] Preferably, a threaded groove is provided on the split-type base at the position corresponding to the connecting bolt, and the threaded groove is threaded to the connecting bolt.

[0013] Preferably, the inner diameter of the nut is smaller than the inner diameter of the split-type base, and the inner diameter of the fixing ring is larger than the inner diameter of the split-type base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model adopts a split base design, and the upper and lower bases can be quickly disassembled and assembled through side ears and fasteners, which solves the problem that the traditional integral structure needs to be replaced as a whole. After wear, only the nut can be replaced, reducing maintenance costs. At the same time, the elastic liner can buffer the radial stress when the nut moves. Combined with the sliding fit between the guide hole on the fixing ear and the guide rod, it effectively limits the nut offset, reduces jamming caused by processing or installation errors, and improves the overall stability and accuracy of operation.

[0016] 2. The dust scraping components on the front and rear sides of this utility model can remove dust and impurities from the surface of the threaded rod in real time through the sliding contact between the dust scraping ring and the threaded rod. It can also effectively prevent foreign objects from entering the inner wall of the nut. At the same time, this structure reduces the wear of impurities on the mating surface between the nut and the threaded rod. With the stable connection of each component, it significantly enhances the adaptability of the guide seat in complex environments such as dust and humidity, and extends the overall service life of the screw-type window opener.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a nut guide seat for a screw-type window opener, including a split seat body 1. The split design allows for quick disassembly and maintenance, effectively solving the problem of needing to replace the entire structure in traditional integral structures. After wear, only the core component needs to be replaced, reducing maintenance costs. The inner wall of the split seat body 1 has a positioning groove 2, and the inner wall of the positioning groove 2 is provided with an elastic liner 3. The elastic liner 3 can buffer the radial stress generated when the nut 4 moves, reducing component wear and improving operational stability. The nut 4 is provided inside the elastic liner 3, and the nut 4 is threadedly connected to a threaded rod 5. Dust scraping components 6 are connected to both the front and rear sides of the split seat body 1. The dust scraping components 6 can remove dust and impurities from the surface of the threaded rod 5 in real time, preventing foreign objects from entering the mating surface and reducing wear. The split seat body 1 is fixedly connected with two symmetrically arranged fixing ears 7, and the fixing ears 7 have guide holes 8. The inner wall of the guide holes 8 is slidably fitted with a guide rod 9. The cooperation of the two can effectively limit the offset of the nut 4, reduce jamming caused by processing or installation errors, and improve the overall operating accuracy.

[0028] Specifically, the split-type base 1 includes an upper base 101 and a lower base 102 arranged correspondingly on the upper and lower sides. Side ears 103 are fixed on the left and right sides of the upper base 101 and the lower base 102, and the upper and lower side ears 103 are connected by fasteners 104. The cooperation between the side ears 103 and the fasteners 104 makes the connection between the upper base 101 and the lower base 102 stable and easy to assemble and disassemble.

[0029] Furthermore, the fastener 104 consists of a fixing bolt 1041 and a fixing nut 1042. The fixing bolt 1041 is threadedly connected to the fixing nut 1042, and the structural connection is reliable, which facilitates the quick disassembly and assembly of the split-type base 1 through tightening and loosening operations.

[0030] Furthermore, the side ear 103 has a through hole 105 corresponding to the fixing bolt 1041. The screw of the fixing bolt 1041 passes through the through hole 105 and is threaded to connect to the fixing nut 1042. The through hole 105 provides an assembly channel for the fixing bolt 1041, ensuring that the fastener 104 can be accurately assembled to achieve a stable connection.

[0031] It is worth noting that the dust scraper assembly 6 includes a fixing ring 601, with a dust scraper ring 602 connected to the inner side of the fixing ring 601, and multiple evenly distributed ear plates 603 fixedly connected to the outer side of the fixing ring 601. A connecting bolt 604 is provided on the ear plate 603, and the connecting bolt 604 is movably connected to the split-type base 1. The cooperation between the ear plate 603 and the connecting bolt 604 enables the dust scraper assembly 6 to be stably installed on the split-type base 1, and facilitates disassembly and replacement in the future.

[0032] It is worth noting that the thickness of the dust scraper ring 602 decreases from the outside to the inside. The inner wall of the dust scraper ring 602 slides against the threaded rod 5, which can enhance the fit between the dust scraper ring 602 and the threaded rod 5, improve the dust and impurity removal effect, and reduce the resistance to the movement of the threaded rod 5.

[0033] It is worth mentioning that a threaded groove 605 is provided on the split base 1 at the position corresponding to the connecting bolt 604. The threaded groove 605 is threaded to the connecting bolt 604. The threaded connection method makes the installation and disassembly of the dust scraper assembly 6 more convenient and facilitates maintenance and replacement.

[0034] It is worth emphasizing that the inner diameter of the nut 4 is smaller than the inner diameter of the split-type base 1, and the inner diameter of the retaining ring 601 is larger than the inner diameter of the split-type base 1. This size design ensures that the nut 4 can be stably limited within the split-type base 1, while reserving sufficient space for the cooperation between the dust scraping assembly 6 and the threaded rod 5, ensuring that the dust scraping function is effectively realized.

[0035] Working principle and process: First, the upper seat 101 and lower seat 102 of the split-type seat 1 are assembled into an integral support structure through the side lugs 103 and fasteners 104. The elastic liner 3 in the positioning groove 2 provides elastic restraint for the nut 4. When the threaded rod 5 is driven to rotate, the nut 4, which is threaded to it, avoids excessive radial stress under the buffering effect of the elastic liner 3. At the same time, the guide hole 8 on the fixing lug 7 slides with the guide rod 9, restricting the nut 4 to rotate synchronously with the threaded rod 5 and ensuring that it makes a stable linear motion along the axial direction. During this process, the dust scraping components 6 on the front and rear sides of the split-type seat 1 are fixed by the connecting bolts 604. The dust scraping ring 602 on the inner side of the fixing ring 601 slides and fits with the threaded rod 5, removing dust and impurities from its surface in real time and preventing foreign objects from entering the mating area between the nut 4 and the threaded rod 5. Finally, the nut 4 achieves precise, stable and clean linear motion in the guide seat, providing reliable transmission guidance for the opening and closing of the window opener.
