[0002] With the continuous development of building door and window technology, lift windows, as a common type of window that combines ventilation and lighting functions, are widely used in various buildings. At present, the mainstream lift windows on the market generally use guide wheel mechanisms to achieve the smooth lifting and positioning of the window sash. Specifically, the guide mechanism is usually composed of guide wheels set in the window frame. Through the cooperation between the guide wheels and the frame, the window sash slides along a predetermined trajectory during opening and closing, ensuring the stability and reliability of its movement.

[0003] However, in actual use, due to the need for aesthetics, sealing, and compactness in the overall structural design of the lift window, the space inside the window frame for the installation of the guide mechanism is relatively limited. After long-term and frequent use, the bearings of the guide wheels are prone to wear due to friction, requiring regular lubrication to reduce friction and ensure smooth movement. However, in actual operation, due to the limited space inside the frame, it is often difficult for operators to replenish the lubricant to the guide wheels, especially when the guide wheels are in a deep position or are obstructed by other structures. The difficulty of replenishing the lubricant increases significantly, thus affecting the performance of the lift window. Utility Model Content

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: a guide mechanism for lifting windows, including a frame 1, a glass window 2, and a drive gear 3. The drive gear 3 is driven by a motor, which is prior art and will not be described in detail here. Movable grooves 6 are provided on both the left and right sides of the inner wall of the frame 1. Movable plates 4 are fixedly installed on both the left and right sides of the rear glass window 2. Bearings 7 are installed on the upper part of the movable plates 4, and guide wheels 5 are fixedly installed on the inner ring wall of the bearings 7. A storage groove 8 is provided on the upper side of the interior of the movable plates 4, and an output hole 11 is provided at the bottom of the inner wall of the storage groove 8. An input hole 19 is provided on the top wall; the front side of the movable plate 4 is meshed with the drive gear 3 and slidably connected to the inner wall of the movable groove 6, so that the two movable plates 4 are driven to move upward by the drive gear 3, thereby driving the rear glass window 2 to rise. The drive gear 3 is rotatably connected to the inside of the frame 1. The lower part of the output holes 11 on the left and right sides is in contact with the bearing 7 at one end. The guide wheel 5 is movably connected to the inner wall of the movable groove 6, so that the lubricant is guided to one side of the bearing 7 through the output hole 11, increasing its lubricity, thereby improving the lubricity of the guide wheel 5.

[0026] In use, the blocking component is first driven to keep the output hole 11 unobstructed. Then, the lubricant in the storage tank 8 is guided to one side of the bearing 7 through the output hole 11 to increase its lubricity and maintain the smooth rotation of the guide wheel 5. After completion, the blocking component is inserted into the inner wall of the output hole 11 to block it for subsequent replenishment. This allows the lubricant to be replenished without the need for operators to use additional tools. When the rear glass window 2 rises, its drive gear 3 meshes with the front side of the moving plate 4, driving the moving plate 4 to rise along the inner wall of the moving groove 6. The guide wheel 5 guides its movement trajectory, increasing the stability of the rear glass window 2 during the rising process, thereby improving the overall performance of the lift window.

[0027] Example 2: Based on Example 1, in order to block the output hole 11, a groove 10 is provided on the upper part of the side of the movable plate 4 near the glass window 2. A lever 9 is slidably connected to the upper side of the inner wall of the groove 10, and a slide plate 13 is slidably connected to the lower side of the inner wall. Elastic members 12 are fixedly installed on the adjacent side of the left and right slide plates 13, and rubber plugs 14 are fixedly installed on the lower part of the opposite side. Guide holes 15 are provided on the opposite part of the left and right rubber plugs 14. The rubber plugs 14 are inserted into the lower inner wall of the output hole 11, and the left and right sides are... The adjacent ends of the elastic element 12 are fixedly installed on the inner wall of the slide groove 10, so that the elastic force of the elastic element 12 pushes the rubber plug 14 to always be in the plugged state with the output hole 11 for subsequent opening and use; the bottom of the dial plate 9 is fixedly installed between the slide plate 13 and the top penetrates the slide groove 10. When the dial plates 9 on both sides move to the maximum stroke, they use the guide hole 15 on one side of the rubber plug 14 to keep the output hole 11 unobstructed. Conversely, after the dial plate 9 is reset, the rubber plug 14 is reset and inserted into the output hole 11 to block it.

[0028] Pulling the levers 9 on both sides moves them towards each other along the inner wall of the slide groove 10, and drives the slide plate 13 to move synchronously. This compresses the elastic element 12, causing it to be in a compressed state within the inner wall of the slide groove 10, while simultaneously moving the rubber plug 14. At this time, the levers 9 move to their maximum stroke, thus using the guide hole 15 to keep the output hole 11 unobstructed. This guides the lubricant in the storage tank 8 to one side of the bearing 7 to increase its lubrication and maintain the smooth rotation of the guide wheel 5. After completion, the levers 9 are released, and the elastic force of the elastic element 12 pushes the slide plate 13 back to its original position, causing the rubber plug 14 to return to its original position and insert into the inner wall of the output hole 11 to block it for subsequent replenishment. This allows for replenishment of lubricant without the need for additional tools from the operator.

[0029] Example 3: Based on Example 2, in order to facilitate the replenishment of lubricant into the storage tank 8, a fitting groove 18 is provided on the inner wall of the input hole 19, a rubber cover plate 16 is installed on the top of the movable plate 4, a rubber protrusion 20 is fixedly installed on the lower outer side of the rubber cover plate 16, and a fastener 17 is fixedly installed on the adjacent side of the left and right rubber cover plates 16; the lower part of the rubber cover plate 16 is inserted into the inner wall of the input hole 19, and the rubber protrusion 20 is inserted into the inner wall of the fitting groove 18, so that the input hole 19 is blocked by the cooperation of the rubber cover plate 16 and the rubber protrusion 20, and the fastener 17 is inserted into the top of the movable plate 4, so that the rubber cover plate 16 is opened by pressing the fastener 17 upward, so that lubricant can be injected into the storage tank 8 through the input hole 19.

[0030] When injecting lubricant into the storage tank 8, first pull the latch 17 to disengage from the top of the moving plate 4. At the same time, move the rubber cover 16 upward and disengage the rubber protrusion 20 from the mating groove 18. At this time, replenish the lubricant into the storage tank 8 through the input hole 19. After completion, reset the rubber cover 16 and insert it into the inner wall of the input hole 19. At the same time, push the rubber protrusion 20 to gradually connect with the mating groove 18 and deform it to increase the stability of the rubber cover 16 connection and facilitate subsequent opening and use.

[0031] The working process of this utility model is as follows:

[0032] In use, the two levers 9 are pulled and moved towards each other along the inner wall of the slide 10, which in turn moves the slide plate 13 synchronously. This compresses the elastic element 12, causing it to be in a compressed state within the inner wall of the slide 10, while simultaneously moving the rubber plug 14. At this point, the levers 9 move to their maximum stroke, thus using the guide hole 15 to keep the output hole 11 unobstructed. This allows the lubricant in the storage tank 8 to be guided to one side of the bearing 7 to increase its lubrication and maintain the smooth rotation of the guide wheel 5. After this is completed, the levers 9 are released, and the elastic force of the elastic element 12 pushes the slide plate 13 back to its original position, causing the rubber plug 14 to be inserted back into the inner wall of the output hole 11 to block it for subsequent use. This allows the lubricant to be replenished without the need for additional tools. When the rear glass window 2 rises, its drive gear 3 meshes with the front of the moving plate 4, causing the moving plate 4 to rise along the inner wall of the moving groove 6. The guide wheel 5 guides its movement trajectory, increasing the stability of the rear glass window 2 during the rising process and thus improving the overall performance of the lift window.

[0033] When injecting lubricant into the storage tank 8, first pull the latch 17 to disengage from the top of the moving plate 4. At the same time, move the rubber cover 16 upward and disengage the rubber protrusion 20 from the mating groove 18. At this time, replenish the lubricant into the storage tank 8 through the input hole 19. After completion, reset the rubber cover 16 and insert it into the inner wall of the input hole 19. At the same time, push the rubber protrusion 20 to gradually connect with the mating groove 18 and deform it to increase the stability of the rubber cover 16 connection and facilitate subsequent opening and use.
