Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to an anti-fall-off component and a door or window sash incorporating the anti-fall-off component. Background Technology

[0002] Currently, door and window sashes mainly consist of sash frame profiles 10 and glass panels 20. When installing and fixing the sash frame profiles 10 and glass panels 20, both are generally secured using glass sealing strips 30. Figure 1 and Figure 2 As shown. However, the door and window sashes of this structure have the following defects:

[0003] 1. When the door and window sash is large, the locking force of the glass sealant strip 30 to the glass panel 20 and the sash frame profile 10 is obviously insufficient. This can easily lead to loosening and deformation between the glass sealant strip 30, the glass panel 20 and the sash frame profile 10 during the handling or sliding and opening / closing of the door and window sash. This can cause the width of the door and window sash to exceed the standard, resulting in poor sealing and overlapping at the hook part of the door and window sash, which in turn affects the product performance of the door and window sash.

[0004] Specifically, such as Figure 3a As shown, the width W of the door and window sashes is within the reference range; at this time, after the two door and window sashes overlap, as shown... Figure 4a As shown, AT material 40 (i.e., waterstop line) is embedded in the hook part of both door and window sashes. The inner and outer sides of the hook parts of the two door and window sashes are the same, so the AT material 40 of one door and window sash and the sash frame profile 10 of the other door and window sash are effectively sealed and overlapped, so that outdoor air, water, temperature and other factors cannot penetrate into the indoor side, and the performance of the door and window sashes is guaranteed.

[0005] When loosening and deformation occur between the glass sealing strip 30, the glass panel 20, and the sash frame profile 10, such as Figure 3b As shown, the width of the door and window sashes has increased from the original W to W+α, exceeding the baseline; at this time, after the two door and window sashes overlap, as... Figure 4b As shown, the two door and window sashes are misaligned at the hook-up part, and the inner and outer surfaces at this point are not the same. This causes the sealing overlap between the AT material 40 of one door and window sash and the sash frame profile 10 of the other door and window sash to fail, resulting in the inability to seal. This allows outdoor air, water, and temperature to enter the indoor side, which in turn makes it impossible to guarantee the product performance of the door and window sashes.

[0006] 2. When installing the glass panel 20, it is necessary to adjust the distance L between the glass panel 20 and the sash frame profile 10, such as... Figure 2 As shown, the glass sealing strip 30 can only be installed after the spacing L is adjusted, which reduces the assembly efficiency of the door and window sashes.

[0007] 3. When installing the glass sealant strip 30, if... Figure 2 As shown, when the pressing force of the glass sealant strip 30 in the pressing direction is too large, it is easy to cause the sash frame profile 10 to bulge, which may cause the two door and window sashes to fail to seal at the AT material 40, thus failing to guarantee the performance of the product. Summary of the Invention

[0008] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an anti-detachment component that effectively improves the fixing reliability of the frame profile and the face material.

[0009] To achieve the above objectives, the present invention provides an anti-detachment component for preventing the face material and the frame profile holding the face material from detaching from each other. The anti-detachment component is disposed between the face material and the frame profile holding the face material. The anti-detachment component includes a face material abutment portion and a profile abutment portion fixed to each other. The face material abutment portion is disposed on the outer periphery of the face material and abuts against it. The profile abutment portion is disposed in an installation opening in the frame profile for installing the face material and abuts against the frame profile. In the anti-detachment component of this application, the tight abutment between the face material abutment portion and the face material, and the tight abutment between the profile abutment portion and the frame profile, effectively locks the face material and the frame profile, improving their fixing reliability. This effectively prevents the face material and frame profile from loosening and detaching from each other during handling or pushing / pulling / closing of goods equipped with the anti-detachment component, thus preventing the product dimensions from exceeding the reference and ultimately reliably ensuring the airtight performance of the product. Meanwhile, after the face material is installed into the frame profile, the anti-detachment component has already tightly locked the face material and the frame profile together. In this way, on the one hand, there is no need to adjust the spacing between the face material and the frame profile before installing the fixing strip, which greatly improves the assembly efficiency of the product. On the other hand, when installing the fixing strip, the contact point between the anti-detachment component and the frame profile can generate a reverse force opposite to the pressing force of the fixing strip, which limits the frame profile from bulging outward due to excessive pressing force of the fixing strip, thus ensuring the airtight performance of the product.

[0010] The preferred embodiment of the above technical solution is as follows: the face material abutting part includes a front abutting part, which is used to abut against the front of the face material and to be fixedly connected with the front of the face material, so as to ensure that the anti-detachment component firmly fixes the face material and increases the locking force of the anti-detachment component on the face material and the frame profile.

[0011] A preferred embodiment of the above technical solution is as follows: the profile abutment extends integrally and obliquely from the outer surface of the front abutment and is disposed between the front abutment and the frame profile along the thickness direction of the face material. The frame profile has a profile protrusion located in the installation opening, and the profile abutment is used to abut against the side of the profile protrusion. In this way, the anti-detachment component is tightly abutted against the frame profile through the profile abutment and is also tightly engaged with the frame profile through the profile abutment. This not only increases the locking force of the anti-detachment component on the face material and the frame profile, preventing loosening, but also plays a certain role in positioning during installation and limiting after installation.

[0012] The preferred embodiment of the above technical solution is as follows: the face material abutting part further includes a side abutting part, the side abutting part is integrally bent and extended from the end of the front abutting part, the side abutting part is used to abut against the side of the face material and to be fixedly connected with the side of the face material, thereby strengthening the fixation between the anti-detachment component and the face material, further ensuring the fixation reliability between the anti-detachment component and the face material, and thus improving the reliability of preventing loosening.

[0013] A preferred embodiment of the above technical solution is that a fixing tape is fixedly provided on both the surface of the front abutment portion facing the face material and the surface of the side abutment portion facing the face material. Preferably, double-sided tape can be used to facilitate the fixed connection between the front abutment portion and the side abutment portion and the face material, and also to reduce costs.

[0014] A preferred embodiment of the above technical solution is as follows: the anti-detachment component further includes a pad portion, which extends integrally and obliquely from the outer surface of the side abutment portion and is disposed between the side abutment portion and the frame profile along the insertion direction of the face material insertion and installation opening. The pad portion is used to abut against the frame profile. This eliminates the need for a separate pad between the face material and the frame profile, reducing the number of parts in the product and thus lowering the product cost.

[0015] This invention also provides a door / window sash, comprising a sash frame profile with an installation opening, a sash surface material held in the installation opening, and an anti-detachment component as described above. The anti-detachment component is disposed between the sash frame profile and the sash surface material. The surface material abutting portion of the anti-detachment component is located on the outer periphery of the sash surface material and abuts against it. The profile abutting portion of the anti-detachment component is located in the installation opening of the sash frame profile and abuts against it. By providing the anti-detachment component in the door / window sash, the fixing reliability of the sash frame profile and the sash surface material is effectively improved, and the sash frame profile is prevented from bulging, thereby ensuring the performance of the door / window sash. Simultaneously, there is no need to adjust the spacing between the sash frame profile and the sash surface material, thus improving the assembly efficiency of the door / window sash.

[0016] The preferred embodiment of the above technical solution is as follows: the door and window sash further includes a fixing strip, which is located in the installation opening of the sash frame profile and is pressed and fixed between the sash frame profile and the sash surface material along the thickness direction of the sash surface material, thereby further increasing the locking force on the sash frame profile and the sash surface material and ensuring the performance of the door and window sash.

[0017] The preferred embodiment of the above technical solution is: the anti-detachment component is provided on both the indoor and outdoor sides of the sash material to further increase the locking force on the sash frame profile and the sash material, and to ensure the performance of the door and window sash.

[0018] As described above, the anti-fall-off components and door / window sashes of the present invention have the following beneficial effects:

[0019] This application achieves a tight fit between the face material and the frame material of the anti-detachment component through the tight fit between the face material abutting part and the profile abutting part of the anti-detachment component, effectively locking the face material and frame material together. This effectively prevents the face material and frame material from loosening during handling or pushing / pushing / closing of the product equipped with the anti-detachment component, reliably ensuring the airtightness of the product. Furthermore, after the anti-detachment component tightly locks the face material and frame material together, the fixing strip can be installed without adjusting the spacing between the face material and frame material, improving the assembly efficiency of the product and preventing the frame material from bulging outward due to excessive pressure from the fixing strip, thus ensuring the airtightness of the product.

[0061] like Figure 5 and Figure 6 As shown, this application provides an anti-fall-off component 50 and a door / window sash equipped with the anti-fall-off component 50. For ease of description, the directions in the following embodiments are defined as follows: the interior and exterior directions of the door / window sash are defined as the front-to-back direction, with the exterior side being the front direction and the interior side being the rear direction; the front-to-back direction is also the thickness direction of the door / window sash; the width direction of the door / window sash is defined as the left-to-right direction; and the height direction of the door / window sash is defined as the up-to-down direction. Based on this, Figure 7In the view shown, the top and bottom sides of the paper are the front and back directions, respectively; the left and right sides of the paper are the left and right directions, respectively; and the front and back sides of the paper are the top and bottom directions, respectively.

[0062] like Figures 5 to 7 As shown, the anti-detachment component 50 of this application is used to be disposed between the face material 60 and the frame profile 80, with the face material 60 held in the mounting opening 11 of the frame profile 80. By providing the anti-detachment component 50, the locking force between the face material 60 and the frame profile 80 is improved, that is, the firmness of the fixed connection between the face material 60 and the frame profile 80 is improved, preventing the face material 60 and the frame profile 80 holding the face material 60 from detaching from each other. Figure 8 and Figure 9 As shown, the anti-detachment component 50 involved in this application includes a face material abutment portion 51 and a profile abutment portion 52 fixed to each other; after the anti-detachment component 50 is disposed between the face material 60 and the frame profile 80, as... Figures 5 to 7 As shown, the surface material abutting part 51 of the anti-detachment component 50 is disposed on the outer periphery of the surface material 60 and abuts against the surface material 60, and the profile abutting part 52 of the anti-detachment component 50 is disposed in the mounting opening 11 of the frame profile 80 and abuts against the frame profile 80.

[0063] When the anti-fall-off component 50 involved in this application is applied in, for example... Figure 5 In the case of the door and window sash shown, the aforementioned surface material 60 is the sash surface material 70 of the door and window sash, and the aforementioned frame profile 80 is the sash frame profile 10 of the door and window sash. The following description, taking the installation of the anti-detachment component 50 in the door and window sash as an example, will elaborate on the preferred structure of the anti-detachment component 50 and the preferred structure of the door and window sash with the anti-detachment component 50 installed. Figures 5 to 7 As shown, the door and window sash involved in this application includes a sash frame profile 10 having an installation opening 11, a sash surface material 70 held in the installation opening 11, and the aforementioned anti-detachment component 50. The anti-detachment component 50 is disposed between the sash frame profile 10 and the sash surface material 70. The surface material abutting portion 51 of the anti-detachment component 50 is located on the outer periphery of the sash surface material 70 and abuts against the sash surface material 70. The profile abutting portion 52 of the anti-detachment component 50 is located in the installation opening 11 of the sash frame profile 10 and abuts against the sash frame profile 10.

[0064] When the aforementioned anti-fall-off component 50 is used in door and window sashes, it has the following beneficial effects:

[0065] 1. Through the tight contact between the face material abutment part 51 and the sash face material 70, and the tight contact between the profile abutment part 52 and the sash frame profile 10, the sash face material 70 and the sash frame profile 10 can be locked in place. Even when the door and window sash is large, the sash face material 70 and the sash frame profile 10 can still be reliably locked, thereby improving the connection firmness between the sash face material 70 and the sash frame profile 10. The sash face material 70 is reliably fixed and locked in the installation opening 11 of the sash frame profile 10, effectively preventing the sash face material 70 and the sash frame profile 10 from loosening and falling off each other during the handling or sliding opening and closing of the door and window sash equipped with the anti-fall-off component 50, thus playing a role in preventing the door and window sash from loosening and deforming. In this way, the dimensions of the door and window sashes are effectively prevented from exceeding the standard. When two adjacent door and window sashes overlap, the AT material 40 of one door and window sash and the sash frame profile 10 of the other door and window sash can effectively seal the overlap, preventing outdoor air, water, temperature, etc. from entering the indoor side, and ultimately reliably ensuring the airtight performance of the door and window sashes. The anti-fall-off component 50 is very suitable for sliding doors, sliding sashes and other products, especially for panoramic sliding doors.

[0066] 2. During the assembly of the door and window sashes, after the sash panel 70 is inserted into the sash frame profile 10, the anti-detachment component 50 has already tightly locked the sash panel 70 and the sash frame profile 10 together. When subsequently installing the fixing strip 90, firstly, there is no need to adjust the distance between the sash panel 70 and the sash frame profile 10 in the left-right direction before installing the fixing strip 90, thus greatly improving the assembly efficiency of the door and window sashes; secondly, when subsequently installing the fixing strip 90, the fixing strip 90 is pressed between the sash panel 70 and the sash frame profile 10 along the width direction of the door and window sash. During the pressing process of the fixing strip 90, the contact point between the anti-detachment component 50 and the sash frame profile 10 can generate a reverse force opposite to the pressing force of the fixing strip 90, preventing the sash frame profile 10 from bulging outwards in the pressing direction due to excessive pressing force of the fixing strip 90, thereby preventing the dimensions of the door and window sash from exceeding the standard and ensuring the airtight performance of the door and window sash.

[0067] Preferably, such as Figure 7 As shown, the sash frame profile 10 is an aluminum profile, and the sash surface material 70 is at least one glass panel 20. When the sash surface material 70 includes multiple glass panels 20, the multiple glass panels 20 are arranged side by side in the thickness direction of the door and window sash, and a separating pad 21 is provided between the outer edges of two adjacent glass panels 20. Figures 5 to 7 The door and window sash shown includes a sash material 70 comprising two glass panels 20 arranged side by side; and anti-fall-off components 50 are provided on both the indoor and outdoor sides of the sash material 70, that is, anti-fall-off components 50 are provided on the left and right sides of the rear glass panel 20 and the left and right sides of the front glass panel 20, which further increases the locking force on the sash frame profile 10 and the sash material 70, and ensures the performance of the door and window sash.

[0068] Figure 7 In the view, the anti-falling component 50 on the indoor side of the fan-shaped material 70 and the anti-falling component 50 on the outdoor side are arranged as a mirror image. The following... Figure 7 Taking the anti-fall-off component 50 on the left side of the interior of the fan-shaped material 70 in the view as an example, the following description will be elaborated.

[0069] like Figures 6 to 9 As shown, in the anti-fall-off component 50, the surface material abutment portion 51 includes a front abutment portion 511, which abuts against the front of the fan surface material 70, that is, against the indoor rear surface of the rear glass panel 20 in the fan surface material 70. The front abutment portion 511 extends horizontally and vertically. Furthermore, the front abutment portion 511 is fixedly connected to the front of the fan surface material 70, playing a major fixing role, ensuring that the anti-fall-off component 50 firmly fixes the fan surface material 70, and increasing the locking force of the anti-fall-off component 50 on the fan surface material 70 and the fan frame profile 10.

[0070] Furthermore, such as Figures 6 to 9 As shown, the face material abutment portion 51 also includes a side abutment portion 512. The side abutment portion 512 extends forward from the left end of the front abutment portion 511, bending forward towards the outdoor side. The side abutment portion 512 extends straight back and forth and is perpendicular to the front abutment portion 511. The side abutment portion 512 abuts against the left side of the fan face material 70 and is fixedly connected to the left side of the fan face material 70, playing an auxiliary fixing role. By adding the side abutment portion 512, the anti-falling component 50 is fixed to the side surface of the fan face material 70 in the width direction, which strengthens the fixing firmness between the anti-falling component 50 and the fan face material 70, further ensuring the fixing reliability between the anti-falling component 50 and the fan face material 70, and thus improving the reliability of preventing the fan face material 70 and the fan frame profile 10 from loosening.

[0071] Preferably, a fixing tape is fixed on the front surface of the front abutment portion 511 facing the fan material 70 and on the right surface of the side abutment portion 512 facing the fan material 70. The fixing tape can be double-sided tape. The double-sided tape on the front surface of the front abutment portion 511 adheres to the front of the fan material 70, and the double-sided tape on the right surface of the side abutment portion 512 adheres to the left side of the fan material 70. This facilitates the fixed connection between the front abutment portion 511 and the side abutment portion 512 of the anti-detachment component 50 and the fan material 70. The operation is convenient, easy to implement, and can also reduce costs.

[0072] Preferably, such as Figure 9 As shown, the anti-detachment component 50 is also provided with an arc-shaped connecting part 54, which is connected between the front abutment part 511 and the side abutment part 512, so that the corners of the anti-detachment component 50 are smooth and without sharp edges.

[0073] Furthermore, such as Figures 6 to 9As shown, in the anti-detachment component 50, the profile abutment portion 52 extends obliquely from the rear surface of the front abutment portion 511, and the profile abutment portion 52 is obliquely positioned such that it gets closer to the sash frame profile 10 as it moves towards the center in the width direction of the door / window sash. That is, the profile abutment portion 52 extends obliquely to the right rear from the rear surface of the front abutment portion 511. Thus, the profile abutment portion 52 is positioned between the front abutment portion 511 and the sash frame profile 10 in the front-rear direction, and the end of the profile abutment portion 52 away from the front abutment portion 511 abuts against the sash frame profile 10. Preferably, the sash frame profile 10 has a profile protrusion 12 located in the mounting opening 11 at the end of the profile abutment portion 52, and the end of the profile abutment portion 52 abuts against the left side of the profile protrusion 12. In this way, while the anti-detachment component 50 is tightly abutted and engaged with the fan frame profile 10 through the profile abutment part 52, it is also tightly locked with the fan frame profile 10 through the profile abutment part 52. This can not only increase the locking force of the anti-detachment component 50 on the fan surface material 70 and the fan frame profile 10 to prevent loosening, but also play a certain role in positioning during installation and limiting after installation.

[0074] Furthermore, such as Figures 6 to 9 As shown, the fan frame profile 10 includes a main profile 13, a secondary profile 14, and a connecting profile 15. The main profile 13 is L-shaped and has a longitudinal section 131 extending forward and backward and a horizontal section 132 extending left and right. The secondary profile 14 extends forward and backward and is arranged opposite to the longitudinal section 131 of the main profile 13. The connecting profile 15 extends left and right and is engaged between the longitudinal section 131 of the main profile 13 and the secondary profile 14. The inner areas of the main profile 13, the secondary profile 14, and the connecting profile 15 are installation openings 11. Figure 7 In the embodiment shown, the sub-profile 14 is distributed on the outdoor side of the fan-shaped profile 70, and the horizontal section 132 of the main profile 13 is distributed on the indoor side of the fan-shaped profile 70. The profile protrusion 12 on the outdoor side of the fan frame profile 10 protrudes integrally to the left from the rear end of the sub-profile 14 and abuts against the profile abutting part 52 of the anti-falling component 50 on the outdoor side. The profile protrusion 12 on the indoor side of the fan frame profile 10 protrudes integrally forward from the front surface of the horizontal section 132 of the main profile 13 and abuts against the profile abutting part 52 of the anti-falling component 50 on the indoor side. Of course, in other embodiments, the sub-profile 14 may be distributed on the indoor side of the fan-shaped profile 70, and the horizontal section 132 of the main profile 13 may be distributed on the outdoor side of the fan-shaped profile 70. In this case, the profile protrusion 12 on the outdoor side of the fan frame profile 10 protrudes backward integrally from the rear surface of the horizontal section 132 of the main profile 13 and abuts against the profile abutting part 52 of the anti-falling component 50 on the outdoor side. The profile protrusion 12 on the indoor side of the fan frame profile 10 protrudes to the right integrally from the front end of the sub-profile 14 and abuts against the profile abutting part 52 of the anti-falling component 50 on the indoor side.

[0075] Preferably, such as Figures 6 to 9As shown, in the anti-fall-off component 50, the end of the profile abutment portion 52 away from the front abutment portion 511 has a first abutment section 55 extending straight towards the center in the width direction of the door / window sash. The first abutment section 55 continues to extend straight to the right along the extending direction of the profile abutment portion 52. For the anti-fall-off component 50 on the indoor side: the rear end face of the first abutment section 55 contacts and engages with the front surface of the horizontal section 132 of the main profile 13 in the sash frame profile 10, and the right end face of the first abutment section 55 contacts and engages with the left side face of the profile protrusion 12 on the main profile 13 in the sash frame profile 10. For the anti-fall-off component 50 on the outdoor side: the right end face of the first abutment section 55 contacts and engages with the left side face of the profile protrusion 12 on the secondary profile 14 in the sash frame profile 10. The first abutting section 55, which extends in a straight line, increases the contact surface between the profile abutting part 52 and the fan frame profile 10, improves the reliability of the engagement between the profile abutting part 52 and the fan frame profile 10, ensures that the two are always tightly engaged, and further improves the reliability of preventing the fan surface material 70 and the fan frame profile 10 from loosening.

[0076] Furthermore, such as Figures 6 to 9 As shown, the anti-fall-off component 50 also includes a pad portion 53, which extends integrally and obliquely from the outer surface of the side abutment portion 512 and is disposed between the side abutment portion 512 and the fan frame profile 10 along the insertion direction of the fan frame 70 into the installation opening 11. Therefore, for the indoor anti-fall-off component 50: the pad portion 53 extends integrally and obliquely to the left front from the rear end of the side abutment portion 512 near the front abutment portion 511; for the outdoor anti-fall-off component 50: the pad portion 53 extends integrally and obliquely to the left rear from the front end of the side abutment portion 512 near the front abutment portion 511. Furthermore, one end of the pad portion 53 away from the side abutment portion 512 abuts against the right surface of the longitudinal section 131 of the main profile 13 in the fan frame profile 10. By providing a pad 53 on the anti-fall-off component 50 that abuts against the left end of the sash material 70 and the sash frame profile 10, it is possible to eliminate the need to provide an additional pad between the sash material 70 and the sash frame profile 10, thereby reducing the number of parts in the door and window sash and thus lowering the cost of the door and window sash.

[0077] Preferably, such as Figures 6 to 9 As shown, in the anti-fall-off component 50, the end of the pad portion 53 away from the side abutment portion 512 has a second abutment section 56 extending straight towards the center in the thickness direction of the door / window sash. In the indoor anti-fall-off component 50, the second abutment section 56 continues to extend straight forward along the extending direction of the pad portion 53, and in the outdoor anti-fall-off component 50, the second abutment section 56 continues to extend straight backward along the extending direction of the pad portion 53. The left end face of the pad portion 53 contacts and engages with the right surface of the longitudinal section 131 of the main profile 13 of the sash frame profile 10, increasing the contact area between the pad portion 53 and the sash frame profile 10 and improving structural stability.

[0078] Furthermore, such as Figure 5 and Figure 7 As shown, the window sash also includes a fixing strip 90, which is disposed on the side of the anti-detachment component 50 facing away from the longitudinal section 131 of the main profile 13 of the sash frame profile 10. The fixing strip 90 is also located in the mounting opening 11 of the sash frame profile 10 and is pressed and fixed between the sash frame profile 10 and the sash surface material 70 along the thickness direction. Therefore, on the indoor side of the sash surface material 70, the fixing strip 90 is pressed and fixed between the horizontal section 132 of the main profile 13 of the sash frame profile 10 and the sash surface material 70; on the outdoor side of the sash surface material 70, the fixing strip 90 is pressed and fixed between the secondary profile 14 of the sash frame profile 10 and the sash surface material 70. The fixing strip 90 is also known as a glass sealing strip. By setting the fixing strip 90, the locking force on the sash frame profile 10 and the sash surface material 70 is further increased, ensuring the performance of the window sash. Furthermore, after the fixing strip 90 is pressed in, the left end of the fixing strip 90 engages between the front abutment portion 511 and the profile abutment portion 52 of the anti-detachment component 50.

[0079] In summary, the anti-detachment component 50 involved in this application adopts a double-sided snap-fit ​​structure: a profile abutment part 52 is provided on the front side of the sash panel 70 to abut against the sash frame profile 10, which serves to prevent the sash panel 70 from detaching from the sash frame profile 10; a pad part 53 is provided on the side side of the sash panel 70 to abut against the sash frame profile 10, which serves as a glass pad, thereby reducing the number of door and window sash components and achieving the purpose of reducing costs. In addition, the front-to-back distance between the end of the profile abutment part 52 on one side of the anti-detachment component 50 and the front abutment part 511, and the left-to-right distance between the end of the pad part 53 on the other side of the anti-detachment component 50 and the side abutment part 512 are set according to actual needs to meet different sizes of installation openings 11.

[0080] Furthermore, the anti-detachment component 50 with the above structure is an integrally molded part, which can be a sheet metal part or an injection molded part. The profile abutment part 52 and the pad part 53 on both sides of the anti-detachment component 50 are elastic buckle functional parts with a certain elasticity, which improves the tight engagement effect with the fan frame profile 10.

[0081] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
