DETAILED DESCRIPTION

[0044] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0045] See Figures 1 to 3 , Figure 1 1 shows a structural diagram of a glass bracket assembly in an embodiment of the present application. Figure 2 and Figure 3 They respectively indicated Figure 1 Enlarged views of two different examples of the structure shown at A. An embodiment of the present application provides a glass holder assembly, which includes: glass 11, a holder 12 and an injection molding glue 13. The holder 12 includes a bracket portion 121 and a retaining portion 122 connected to the bracket portion 121. A slot 1220 extending toward the bracket portion 121 is formed on the side of the retaining portion 122 away from the bracket portion 121, and the edge of the glass 11 is inserted into the slot 1220. A sealing portion 123 is provided on the holder 12, which is circumferentially arranged around the notch of the slot 1220. The sealing portion 123 is used to abut and cooperate with the molding mold of the glass holder assembly. When the sealing portion 123 abuts the molding mold, the notch of the slot 1220 is in a closed state. The injection molding glue 13 is filled in the slot 1220, and the edge of the glass 11 is integrally injection molded with the retaining portion 122 by the injection molding glue 13.

[0046] The above-mentioned glass bracket assembly is provided with a sealing portion 123 circumferentially arranged around the notch of the slot 1220 on the bracket 12. Therefore, during the production process, after the sealing portion 123 abuts against the molding mold, it can accurately position the bracket 12 and the glass 11, and can make the notch of the slot 1220 in a completely closed state. Then, the glass 11 and the bracket 12 are made into a whole through the PU edging one-piece injection molding process, thereby achieving the advantages of reducing process steps, improving product performance strength and precision, and having a short production cycle and a high yield rate. In addition, the assembly of the bracket 12 and the glass 11 adopts one-piece injection molding, which can eliminate the gluing and curing process and greatly reduce the manufacturing cost.

[0047] In some embodiments, the material of the injection molding glue 13 includes but is not limited to thermoplastic elastomer (TPE), polyurethane (PU), etc., which can be flexibly selected and set according to actual conditions and is not specifically limited in this embodiment.

[0048] See also Figure 1 、 Figure 4 and Figure 5 In one embodiment, the retaining portion 122 includes two clamping plates 1221 spaced apart from each other. One end of each clamping plate 1221 is connected to the bracket portion 121, and the two clamping plates 1221 and the bracket portion 121 together form a slot 1220. The sealing portion 123 includes two first sealing strips and two second sealing strips. The two first sealing strips are respectively arranged at the edges of the clamping plates 1221, and the two second sealing strips are respectively arranged on opposite sides of the bracket portion 121. One end of the two first sealing strips is connected by one of the second sealing strips, and the other ends of the two first sealing strips are connected by the other second sealing strip. In this arrangement, the two first sealing strips and the two second sealing strips are connected end to end, so that the sealing portion 123 has a closed annular structure. In this way, the sealing portion 123 is circumferentially arranged around the notch of the slot 1220. Furthermore, during the production process, after the sealing portion 123 abuts the forming mold, it not only accurately positions the bracket 12 and the glass 11, but also ensures that the notch of the slot 1220 is in a completely sealed state.

[0049] It should be noted that, in one embodiment, the "sealing portion 123" can be "a part of the bracket 12", that is, the "sealing portion 123" is integrally formed with the "other parts of the bracket 12"; it can also be an independent component that is separable from the "other parts of the bracket 12", that is, the "sealing portion 123" can be manufactured independently and then combined with the "other parts of the bracket 12" into a whole. In another embodiment, the "first sealing strip" can be "a part of the retaining portion 122", that is, the "first sealing strip" is integrally formed with the "other parts of the retaining portion 122"; it can also be an independent component that is separable from the "other parts of the retaining portion 122", that is, the "first sealing strip" can be manufactured independently and then combined with the "other parts of the retaining portion 122" into a whole. In another embodiment, the "second sealing strip" can be "a part of the bracket portion 121", that is, the "second sealing strip" and the "other parts of the bracket portion 121" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the bracket portion 121", that is, the "second sealing strip" can be manufactured independently and then combined with the "other parts of the bracket portion 121" into a whole.

[0050] In this embodiment, the sealing portion 123, the retaining portion 122, and the bracket portion 121 are, for example, an integrated structure. Furthermore, the bracket 12 can be made of either metal or non-metallic materials. For example, the bracket 12 is made of plastic and is integrally injection molded. For another example, the bracket 12 is made of metal and is integrally molded using die-casting or sheet metal molding.

[0051] In addition, the cross-sectional profile of the sealing portion 123 along its circumferential direction includes but is not limited to a triangle (such as Figure 2 As shown), arc (as Figure 3 As shown in the figure), rectangle, pentagon and other regular shapes and other irregular shapes can be flexibly adjusted and set according to actual needs.

[0052] In some embodiments, see Figure 1 and Figure 2 The sealing portion 123, the retaining portion 122, and the bracket portion 121 are an integrated structure. The bracket 12 is a plastic frame. The sealing portion 123 has a triangular cross-sectional profile along its circumferential direction, and the tip of the sealing portion 123 abuts against the forming mold. As a result, when the sealing portion 123 abuts against the forming mold, due to the triangular cross-sectional profile of the sealing portion 123 along its circumferential direction, the sealing portion 123 is easily deformed by pressure, which facilitates interference with the forming mold, thereby achieving better sealing performance.

[0053] When the tip of the sealing portion 123 contacts the mold, the height of the sealing portion 123 protruding from the end surface of the retaining portion 122 affects the amount of interference with the mold. The greater the height of the sealing portion 123 protruding from the surface of the retaining portion 122, the greater the interference between the sealing portion 123 and the mold, thereby enhancing sealing performance. Conversely, the smaller the height of the sealing portion 123 protruding from the end surface of the retaining portion 122, the less interference between the sealing portion 123 and the mold.

[0054] Of course, as some optional solutions, when the bracket 12 is a plastic part, the cross-sectional profile of the sealing portion 123 along its circumferential direction can also be set to be arc-shaped. Compared with the method of setting the cross-sectional profile to be arc-shaped, the cross-sectional profile is set to be triangular, which has better sealing performance.

[0055] In some embodiments, see Figure 2 The distance h1 between the tip of the sealing portion 123 and the surface of the retaining portion 122 includes, but is not limited to, 0.1 mm ≤ h1 ≤ 0.5 mm, and specifically, for example, 0.1 mm, 0.3 mm, or 0.5 mm. Furthermore, the angle a of the tip of the sealing portion 123 is 20° ≤ a ≤ 60°, and specifically, for example, 20°, 30°, 40°, 50°, or 60°. Furthermore, the bottom width b of the sealing portion 123 is 0.3 mm ≤ b ≤ 1.5 mm, and specifically, for example, 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, or 1.5 mm.

[0056] Based on the above embodiment, the tip of the sealing portion 123 is chamfered to form a rounded corner. In this way, when the tip of the sealing portion 123 contacts the forming mold, the rounded corner contacts the forming mold, which can reduce the damage to the forming mold. Optionally, the radius R1 of the rounded corner includes but is not limited to 0 <R1≤0.1mm。

[0057] In some embodiments, refer to Figure 1 and Figure 3 , the sealing portion 123, the holding portion 122, and the bracket portion 121 are an integrated structure. The bracket 12 is a metal frame, and the cross-sectional profile of the sealing portion 123 along its circumferential direction is arc-shaped. Thus, when the sealing portion 123 abuts against the molding die, due to the relatively high hardness of the material of the metal frame and the arc-shaped cross-sectional profile of the sealing portion 123 along its circumferential direction, it not only has good sealing performance but also can reduce the damage caused to the molding die, thereby avoiding the defect that the sealing performance is weakened due to the contact between the sharp corners and the molding die.

[0058] Based on the foregoing embodiments, taking the surface of the holding portion 122 as the reference surface, the maximum height h2 of the outer surface of the sealing portion 123 relative to the reference surface includes but is not limited to 0.05 mm ≤ h2 ≤ 0.35 mm, specifically, for example, 0.05 mm, 0.1 mm, 0.2 mm, or 0.35 mm, etc. In addition, the radius R2 of the arc includes but is not limited to 1 mm < R2 ≤ 5 mm, such as 1 mm, 3 mm, or 5 mm, etc.

[0059] In some embodiments, the wall thickness W of the slot 1220 includes but is not limited to 1 mm < W ≤ 4 mm, specifically, for example, 1 mm, 2 mm, 3 mm, or 4 mm, etc. The wall thickness of the slot 1220 is also the thickness of the clamping plate 1221. When the wall thickness W of the slot 1220 is greater than or equal to 1 mm, the structural strength is relatively large, which can ensure the structural strength of the connection with the glass 11 and enhance the stability; when the wall thickness W of the slot 1220 is less than or equal to 4 mm, it can avoid material waste caused by excessive wall thickness W of the slot 1220.

[0060] Refer to Figure 4 and Figure 5 , in some embodiments, at least one reinforcing rib 1222 is provided on the inner wall of the slot 1220. The reinforcing rib 1222 extends from one end close to the bracket portion 121 inside the slot 到另一端。具体而言,两个夹持板1221彼此相对的侧面上均设有至少一个加强筋1222。如此,加强筋1222不仅能增加保持部122的结构强度,还能起到卡设玻璃11的作用,从而能提高玻璃11与保持部122组合在一起的结构稳定性。

[0061] Specifically, a first guiding surface 1223 is provided at one end of the reinforcing rib 1222 away from the bracket portion 121. Optionally, the first guiding surface 1223 includes but is not limited to a bevel surface or an arc surface, etc., as long as it can play a guiding role for the edge of the glass 11. During the process of inserting the edge of the glass 11 into the inside of the slot 1220, when the edge of the glass 11 contacts the first guiding surface 1223, it is beneficial to smoothly insert the edge of the glass 11 into the inside of the slot 1220 and reduce the collision and friction damage. It should be noted that there seems to be an incomplete sentence in the original text for item where it says "The reinforcing rib 1222 extends from one end close to the bracket portion 121 inside the slot to the other end." The translation is based on the best understanding of the overall context, but this part might need further clarification in the original text for a more accurate translation.

[0062] See also Figure 6 In some embodiments, the retaining portion 122 is provided with at least one through-hole 1224. The injection molding adhesive 13 is provided with a first protrusion 131 that fills the through-hole 1224. And / or, the inner wall of the slot 1220 is provided with at least one second protrusion, which is embedded and fixed inside the injection molding adhesive 13. In this way, after the integral injection molding, the first protrusion 131 of the injection molding adhesive 13 is still fixed in the through-hole 1224, and / or the second protrusion is embedded and fixed inside the injection molding adhesive 13, thereby enhancing the bonding stability between the injection molding adhesive 13 and the retaining portion 122 and preventing the retaining portion 122 from loosening from the edge of the glass 11.

[0063] See also Figure 6 In a specific embodiment, each clamping plate 1221 is provided with at least two through holes 1224 . At least two first protrusions 131 are respectively provided on opposite sides of the injection molded plastic 13 , and each first protrusion 131 is fixed in each through hole 1224 .

[0064] See also Figures 7 to 16 , Figures 7 to 16 The diagram shows the structure of the glass bracket assembly in different states according to the molding process sequence.

[0065] For example, see Figure 9 In some embodiments, an embodiment of the present application provides a forming mold for manufacturing the glass bracket assembly of any of the above embodiments, and the forming mold includes a lower mold 20 and an upper mold 30.

[0066] The lower mold 20 is provided with a first pressing portion 21 for abutting against the first side surface of the glass 11. A first recess 211 is provided on one side of the first pressing portion 21, facing away from the first side surface. Furthermore, the upper mold 30 is provided with a second pressing portion 31 for abutting against the second side surface of the glass 11. A second recess 311 is provided on one side of the second pressing portion 31, facing away from the second side surface.

[0067] When the upper mold 30 and the lower mold 20 are closed, the first pressing portion 21 abuts against the first side surface, the second pressing portion 31 abuts against the second side surface, and the first recess 211 and the second recess 311 cooperate to form a groove 40 that is adapted to the outer shape of the retaining portion 122; that is, the first recess 211 extends to the edge position of one side of the first pressing portion 21, and the second recess 311 extends to the edge position of one side of the second pressing portion 31, so that the retaining portion 122 can be inserted into the groove 40, and the sealing portion 123 is sealed and abutted against the inner wall of the groove 40.

[0068] When the above-mentioned molding mold of the glass holder assembly is in use, after the retaining part 122 is inserted into the groove 40, the edge of the glass 11 is correspondingly inserted into the slot 1220 of the retaining part 122. Since the sealing part 123 is sealed and abutted against the inner wall of the groove 40, the notch of the slot 1220 is in a closed state, with good sealing performance. Moreover, after the injection molding glue 13 is injected into the interior of the slot 1220, it can effectively prevent the injection molding glue 13 from overflowing, prevent flash defects, and effectively improve product quality and production efficiency, thereby achieving the advantages of reducing process steps, improving product performance strength and precision, and having a short production cycle and a high yield rate.

[0069] In some embodiments, in order to enable the injection molding glue 13 to be injected into the interior of the slot 1220, an injection hole is provided on the upper mold 30 and / or the lower mold 20. The specific opening position of the injection hole can be flexibly adjusted and set according to actual needs, as long as the injection molding glue 13 can enter the interior of the slot 1220 through the injection hole after the upper mold 30 and the lower mold 20 are closed.

[0070] See also Figure 10 and Figure 11 In one embodiment, the lower mold 20 further includes a first seal 22 mounted on the first pressing portion 21. The first seal 22 is arranged on the periphery of the first recess 211, and the first seal 22 abuts against the first side surface. In addition, the upper mold 30 further includes a second seal 32 mounted on the second pressing portion 31. The second seal 32 is arranged on the periphery of the second recess 311, and the second seal 32 abuts against the second side surface. In this way, the first seal 22 plays a sealing role, which can prevent the injection molding glue 13 inside the slot 1220 from overflowing through the gap between the first pressing portion 21 and the first side surface during the injection molding process; in addition, the second seal 32 plays a sealing role, which can prevent the injection molding glue 13 inside the slot 1220 from overflowing through the gap between the second pressing portion 31 and the second side surface, thereby improving the product processing quality.

[0071] In some embodiments, the first seal 22 extends, for example, along the edge of the first recess 211 and is disposed around the periphery of the first recess 211. This arrangement surrounds the circumference of the slot 1220, facilitating a complete sealing of the slot 1220. Alternatively, the first seal 22 includes, but is not limited to, a sealing strip or a sealing block. Similarly, the second seal 32 extends, for example, along the edge of the second recess 311 and is disposed around the periphery of the second recess 311. This arrangement surrounds the circumference of the slot 1220, facilitating a complete sealing of the slot 1220. Alternatively, the second seal 32 includes, but is not limited to, a sealing strip or a sealing block.

[0072] In some embodiments, the first pressing portion 21 is provided with a first mounting groove 212, and the first sealing member 22 is installed within the first mounting groove 212. A portion of the material of the first sealing member 22 protrudes outside the first mounting groove 212, and the distance of the protruding portion relative to the pressing surface of the first pressing portion 21 is, for example, 1 mm to 3 mm. When abutting against the first side surface, the first sealing member 22 is deformed by force, with an interference margin of 1 mm to 3 mm, thereby achieving a sealing effect. Similarly, the second pressing portion 31 is provided with a second mounting groove 312, and the second sealing member 32 is installed within the second mounting groove 312. A portion of the material of the second sealing member 32 protrudes outside the second mounting groove 312, and the distance of the protruding portion relative to the pressing surface of the second pressing portion 31 is, for example, 1 mm to 3 mm. When abutting against the second side surface, the second sealing member 32 is deformed by force, with an interference margin of 1 mm to 3 mm, thereby achieving a sealing effect.

[0073] Based on the aforementioned embodiment, a third recess 213 is further provided on one side of the first pressing portion 21, facing away from the first side surface. The depth d3 of the third recess 213 is less than the depth d1 of the first recess 211. The third recess 213 is disposed adjacent to the first recess 211 and surrounds the periphery of the first recess 211. Thus, the third recess 213 and the first recess 211 form a stepped shape on one side of the first pressing portion 21. The third recess 213 is connected to the slot 1220, and the injection molding compound 13 is not only injected into the slot 1220 but also fills the third recess 213, allowing more injection molding compound 13 to bond with the first side surface. This improves the structural stability of the glass holder assembly.

[0074] In order to improve the sealing performance, the first installation groove 212 is specifically arranged on the periphery of the third recess 213. In this way, the first sealing member 22 is arranged on the periphery of the third recess 213, so that during the injection molding process, it has higher sealing performance and higher molding quality.

[0075] Similarly, a fourth recess 313 is provided on one side of the second pressing portion 31, facing away from the second side surface. The depth d4 of the fourth recess 313 is less than the depth d2 of the second recess 311. The fourth recess 313 is disposed adjacent to the second recess 311 and surrounds the periphery of the second recess 311. Thus, the fourth recess 313 and the second recess 311 form a stepped shape on one side of the second pressing portion 31. The fourth recess 313 is connected to the slot 1220, and the injection molding compound 13 is not only injected into the slot 1220 but also fills the fourth recess 313, allowing more injection molding compound 13 to bond with the second side surface. This improves the structural stability of the glass holder assembly.

[0076] In order to improve the sealing performance, the second installation groove 312 is specifically arranged on the periphery of the fourth recess 313. In this way, the second sealing member 32 is arranged on the periphery of the fourth recess 313, so that during the injection molding process, it has higher sealing performance and higher molding quality.

[0077] See also Figure 12 and Figure 13 In some embodiments, the lower mold 20 further includes a third sealing member 23 mounted on the first pressing portion 21. The first recess 211 is formed on the third sealing member 23, that is, the first recess 211 is indirectly formed on the first pressing portion 21. The third sealing member 23 is made of an elastic material with a hardness lower than that of the first pressing portion 21. It has good sealing performance when abutting against the sealing portion 123, especially when abutting against the sealing portion 123 made of a metal material, it can ensure that the sealing performance does not deteriorate. In addition, the third sealing member 23 also abuts against the first side surface, which can further improve the sealing performance and prevent the injection molding compound 13 from overflowing through the gap between the first pressing portion 21 and the first side surface during the injection molding process. In addition, similarly, the upper mold 30 further includes a fourth sealing member 33 mounted on the second pressing portion 31. The second recess 311 is formed on the fourth sealing member 33. The fourth sealing member 33 also abuts against the second side surface.

[0078] Based on the aforementioned embodiment, the third sealing member 23 is further provided with a fifth recess 231, which is recessed in a direction away from the first side surface. The depth d5 ​​of the fifth recess 231 is less than the depth d1 of the first recess 211. The fifth recess 231 is disposed adjacent to the first recess 211 and surrounds the periphery of the first recess 211. Thus, the fifth recess 231 and the first recess 211 form a stepped shape for the third sealing member 23. The fifth recess 231 is connected to the slot 1220, and the injection molding compound 13 is not only injected into the slot 1220 but also fills the fifth recess 231, allowing more injection molding compound 13 to bond with the first side surface, thereby improving the structural stability of the glass holder assembly. Similarly, the fourth sealing member 33 is further provided with a sixth recess 331, which is recessed in a direction away from the second side surface. The depth d6 of the sixth recess 331 is less than the depth d2 of the second recess 311. The sixth recess 331 is positioned adjacent to the second recess 311 and surrounds the periphery of the second recess 311. Together, the sixth recess 331 and the second recess 311 form a stepped shape for the fourth seal 33. The sixth recess 331 communicates with the slot 1220, allowing the injection molding compound 13 to not only be injected into the slot 1220 but also fill the sixth recess 331. This allows more of the injection molding compound 13 to bond with the second side surface, thereby enhancing the structural stability of the glass holder assembly.

[0079] Please refer to Figures 7 to 9In one embodiment, the molding die further includes a slider 50 slidably disposed on the lower mold 20 along the insertion direction F of the bracket 12, and a push-pull mechanism (not shown) connected to the slider 50. The slider 50 is provided with a seventh recess 51 for receiving the bracket 12. The seventh recess 51 conforms to the shape of the bracket 12. When the push-pull mechanism drives the slider 50 in the insertion direction F, the slider 50 can drive the bracket 12, which is placed in the seventh recess 51, to be inserted into the groove 40. In this way, on the one hand, in the step of inserting and docking the bracket 12 and the glass 11 with each other, the bracket 12 is placed in the seventh recess 51, and the slider 50 drives the bracket 12 to be inserted into the groove 40 along the insertion direction F, so that the bracket 12 can be quickly inserted into the groove 40, with high positioning accuracy and high assembly efficiency; on the other hand, after the injection molding glue 13 is injected into the interior of the slot 1220 and the injection molding glue 13 is solidified, in the mold opening step, the upper mold 30 can be moved upward to separate from the lower mold 20, and then the glass bracket assembly can be taken out upward, so that the unloading efficiency is high.

[0080] See also Figure 9 and Figure 10 In some embodiments, the first pressing portion 21 has a first positioning surface 214 facing the slider 50, and the slider 50 has a second positioning surface 52 facing the first pressing portion 21. When the slider 50 drives the bracket 12 placed in the seventh recess 51 to be inserted into the groove 40, the first positioning surface 214 and the second positioning surface 52 abut against each other, thereby performing a positioning and sealing function. In addition, the inner wall of the seventh recess 51 adjacent to the first recess 211 is aligned with the inner wall of the first recess 211 along the insertion direction F, thereby achieving a high degree of sealing at the junction of the first recess 211 and the seventh recess 51. This also facilitates the smooth insertion of the retaining portion 122 of the bracket 12 into the groove 40. In addition, the front portion of the retaining portion 122 along the insertion direction F is located within the groove 40, and the remaining portion of the retaining portion 122 along the insertion direction F is located in the seventh recess 51. That is, the front portion of the sealing portion 123 on the lower clamping plate 1221 along the insertion direction F is in sealing contact with the inner wall of the first recess 211, and the remaining portion of the sealing portion 123 on the lower clamping plate 1221 along the insertion direction F is in sealing contact with the inner wall of the seventh recess 51. This can improve the sealing performance of the slot 1220. In addition, after the injection molding glue 13 is cured, it is easy to remove the glass holder assembly during the demoulding process. For details, please refer to Figures 14 to 16 , Figure 15 The status shown is compared to Figure 14 In the state shown, it is a schematic diagram showing the upper mold 30 opening upward; Figure 16 The status shown is compared to Figure 15 As for the state shown, it illustrates the structure of the glass bracket assembly being separated upward from the lower mold 20 and the slider 50.

[0081] Based on the above embodiment, in order to smoothly insert the retaining portion 122 of the bracket 12 into the groove 40, a second guide surface 2111 is provided at the end of the first recess 211 close to the slider 50. The second guide surface 2111 may include, but is not limited to, an inclined surface or an arcuate surface, etc., to guide the retaining portion 122. Similarly, a third guide surface 3111 is provided at the end of the second recess 311 close to the slider 50. The third guide surface 3111 may include, but is not limited to, an inclined surface or an arcuate surface, etc., to guide the retaining portion 122.

[0082] Please refer to Figure 9 In one embodiment, the lower mold 20 further includes a support surface 24 for supporting the slider 50 . The bottom of the slider 50 includes a sliding surface 53 slidably disposed on the support surface 24 along the insertion direction F. Thus, when the push-pull mechanism pushes the slider 50 along the insertion direction F, the sliding surface 53 slides along the support surface 24 , providing greater stability and facilitating the precise insertion of the bracket 12 into the groove 40 .

[0083] Specifically, the support surface 24 and the sliding surface 53 include, but are not limited to, planes. Optionally, a first guide member is provided on the support surface 24, and a second guide member is provided on the sliding block to cooperate with the first guide member. The cooperation between the first and second guide members can further improve the operational stability of the bracket 12 and enable the bracket 12 to be accurately inserted into the groove 40.

[0084] See also Figure 9 In one embodiment, a first anti-slip portion 1211 is provided on the outer wall of the bracket portion 121, and a second anti-slip portion 511 that cooperates with the first anti-slip portion 1211 is provided on the inner wall of the seventh recess 51. The first anti-slip portion 1211 and the second anti-slip portion 511 are independently provided, and both include but are not limited to anti-slip grooves. Optionally, the first anti-slip portion 1211 and the second anti-slip portion are, for example, concave and convex, and when the bracket 12 is placed inside the seventh recess 51, the first anti-slip portion 1211 and the second anti-slip portion 511 match each other, thereby achieving a better anti-slip effect. The bracket 12 is stably placed on the slider 50, and in the step of inserting the bracket 12, it is helpful to drive the bracket 12 into the groove 40 along the insertion direction F.
