[0025] In order to enable those skilled in the art in this technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0026] As Figure 1 and Figure 2 shown, to solve the above - mentioned problems, the present invention provides a fastening structure, including: a sealing tube 1, an assembly housing 11, and a tapered sleeve 5. Among them, the sealing tube 1 is used to fix the push - shaft window opener 4, and the push - shaft window opener 4 is coaxially arranged with the sealing tube 1.

[0027] It should be noted that a front cover is disposed at the left end of the sealing tube 1, and a rear cover is disposed at the right end of the sealing tube 1. The front cover and the rear cover are thread - connected to the sealing tube 1 to form a sealing tube passage. In addition, a connecting member is integrally provided on the left side surface of the front cover. The connecting member is mainly used for rotatably connecting and fixing the frame body. The frame body serves as a stable force - bearing carrier and plays a role in stably fixing one end of the sealing tube 1. At the same time, a through - hole is provided at the center of the rear cover, and the through - hole is used for passing through the push - shaft window opener 4.

[0028] An assembly housing 11 is integrally provided on the outer side wall of the push - shaft window opener 4. That is, the assembly housing 11 is a structural component of the push - shaft window opener 4. A first end cover 2 is provided at the left end of the assembly housing 11, and a second end cover 3 is provided at the right end of the assembly housing 11. Among them, both the first end cover 2 and the second end cover 3 are fixedly connected to the assembly housing 11. Preferably, the left end of the assembly housing 11 is thread - connected to the first end cover 2, and the right end of the assembly housing 11 is thread - connected to the second end cover 3. Of course, other connection methods can also be selected, and the connection methods of the first end cover 2, the second end cover 3 and the assembly housing 11 are not specifically limited.

[0029] As Figure 3 and Figure 4As shown in the figure, the first end cover 2 and the second end cover 3 are respectively sleeved and connected to the tapered sleeves 5, and the outer peripheral sides of the two tapered sleeves 5 are respectively abutted against the inner peripheral side of the sealing tube 1. The position state of the assembly housing 11 is locked by the tapered sleeves 5, so that the assembly housing 11 is stably limited. On the other hand, by using the tapered sleeves 5 to assist in limiting the position of the assembly housing 11, the accuracy of the processing lengths of the sealing tube 1 and the assembly housing 11 can be appropriately reduced, and the production and processing costs can be reduced.

[0030] During use, the push-rod window opener 4 is installed into the sealing tube 1, and the two tapered sleeves 5 are respectively fixed to the end faces of the first end cover 2 and the second end cover 3. The two tapered sleeves 5 are respectively stably sleeved on the end faces of the first end cover 2 and the second end cover 3. At the same time, the inner peripheral sides of the two tapered sleeves 5 respectively abut against the outer peripheral sides of the first end cover 2 and the first end cover 2, forming a stable limit on the assembly housing 11, thereby ensuring that the push-rod window opener 4 does not slip or rotate relative to the sealing tube 1, and avoiding the failure of the push-rod window opener 4.

[0031] Specifically, a plurality of screw through holes 6 are arranged in an array on the end face of the tapered sleeve 5. Specifically, two screw through holes 6 are provided, and the two screw through holes 6 are arranged at equal angles on the end face of the tapered sleeve 5. The screw through holes 6 are used for passing through countersunk head screws 7. Further, a plurality of threaded holes 8 are arranged in an array on the end faces of the first end cover 2 and the second end cover 3, and each threaded hole 8 is connected to a countersunk head screw 7. The countersunk head screws 7 pass through the screw through holes 6 to fix the tapered sleeves 5 to the first end cover 2 and the second end cover 3 respectively.

[0032] The inner peripheral side of the tapered sleeve 5 is provided with a first tapered inclined surface 9, and the outer peripheral sides of the first end cover 2 and the second end cover 3 are provided with a second tapered inclined surface 10. The first tapered inclined surface 9 and the second tapered inclined surface 10 are mutually attached. When the tapered sleeve 5 moves from contacting the first end cover 2 to being gradually further sleeved on the outer peripheral side of the first end cover 2, that is, when the tapered sleeve 5 moves to the right relative to the first end cover 2, the inner peripheral side of the tapered sleeve 5 can always remain attached to the outer peripheral side of the first end cover 2, effectively improving the attachment strength between the tapered sleeve 5 and the first end cover 2, and assisting in enhancing the circumferential relative position of the tapered sleeve 5 and the first end cover 2. Similarly, when the tapered sleeve 5 moves from contacting the second end cover 3 to being gradually further sleeved on the outer peripheral side of the second end cover 3, that is, when the tapered sleeve 5 moves to the left relative to the second end cover 3, the inner peripheral side of the tapered sleeve 5 can always remain attached to the outer peripheral side of the first end cover 2, effectively improving the attachment strength between the tapered sleeve 5 and the first end cover 2, and assisting in enhancing the circumferential relative position of the tapered sleeve 5 and the first end cover 2. It effectively ensures that the push-rod window opener 4 does not rotate relative to the sealing tube 1, and avoids the failure of the push-rod window opener 4.

[0033] In one embodiment of the present utility model, the tapered sleeve 5 is provided with a through notch 501 along the axial direction. The notch 501 is used to assist the overall expansion of the tapered sleeve 5. When the contact area between the tapered sleeve 5 and the second tapered slope 10 gradually increases, the overall diameter of the tapered sleeve 5 will continuously increase, and the notch 501 will open by a certain amplitude, enabling the tapered sleeve 5 to be further advanced and engaged with the tapered sleeve 5 under the drive of the countersunk head screw 7.

[0034] In addition, several limiting strips are provided on the inner wall of the sealing tube 1, and several limiting grooves 502 are provided on the outer wall of the tapered sleeve 5. Each limiting strip is snap-connected to a limiting groove 502. Through the mutual cooperation of the limiting strip and the limiting groove 502, the position state of the assembled housing 11 is assisted in being limited, further ensuring that the window opener will not rotate relative to the sealing tube 1 and avoiding the failure of the push-rod window opener 4.

[0035] Sealing gaskets are provided between the first end cap 2 and the sealing tube 1 and between the second end cap 3 and the sealing tube 1. The sealing gaskets can seal the gaps existing between the first end cap 2 and the sealing tube 1. Similarly, the sealing gaskets can seal the gaps existing between the second end cap 3 and the sealing tube 1, improving the sealing effect on the push-rod window opener 4 and effectively avoiding the problem of internal corrosion caused by rainwater and the like entering during use, resulting in functional failure.

[0036] When the present utility model is in use, the push-rod window opener 4 is installed into the sealing tube 1. The two tapered sleeves 5 are respectively fixed to the end faces of the first end cap 2 and the second end cap 3 through the countersunk head screws 7 passing through the screw through holes 6. Each limiting groove 502 is slidably connected to a limiting strip. The countersunk head screws 7 are rotated forward, and the two tapered sleeves 5 are respectively stably sleeved on the end faces of the first end cap 2 and the second end cap 3. At the same time, the tapered sleeve 5 is fixed to the end face of the first end cap 2 through the countersunk head screw 7 passing through the screw through hole 6. The countersunk head screw 7 is rotated forward, and the first tapered slope 9 and the second tapered slope 10 are mutually attached. Each limiting groove 502 is slidably connected to a limiting strip to lock the assembled housing 11. Finally, the front cover and the rear cover are rotated to complete the fastening of the push-rod window opener 4.

[0037] In summary, the outer peripheral side of the tapered sleeve 5 is used to seal the inner peripheral side of the sealing tube 1, the position state of the assembled housing 11 is locked, the assembled housing 11 is stably limited, the assembled housing 11 and the sealing tube 1 are integrated into one body, ensuring that the push-rod window opener 4 will not rotate relative to the sealing tube 1 and avoiding the problem of failure of the push-rod window opener 4.
