DETAILED DESCRIPTION

[0038] The core of the utility model is to provide a ball head seat buckle installation structure. The structural design of the ball head seat buckle installation structure makes it easy to assemble the dimming bracket, the ball head screw and the ball head seat buckle, thereby improving the yield rate.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] The utility model discloses a ball head seat buckle installation structure in an embodiment. The ball head seat buckle installation structure comprises a first clamping component 1, a ball head seat buckle 2 and a ball head component 3.

[0042] Among them, the first clamping component 1 can be the dimming bracket itself or a component of the dimming bracket, the first clamping component 1 includes a plurality of first clamping structures 120 arranged at intervals along the circumferential direction; the ball head seat buckle 2 is provided with a second clamping component and a third clamping component, the second clamping component includes a plurality of second clamping structures 220 arranged at intervals along the circumferential direction, the first clamping component 1 and the ball head seat buckle 2 can move relative to each other in the axial direction to a preparation position where each first clamping structure 120 and each second clamping structure 220 are alternately arranged in the circumferential direction, the first clamping component 1 and the ball head seat buckle 2 can rotate relative to each other at a preset angle from the preparation position to a clamping position where the first clamping structure 120 and the second clamping structure 220 are mutually clamped, so as to limit the first clamping component 1 and the ball head seat buckle 2 in the circumferential direction and the axial direction.

[0043] See also Figure 2 and Figure 4 In the embodiment of the present application, four first clamping structures 120 and four second clamping structures 220 are respectively provided. Figure 2 After turning 45° from the preparation position, you can reach Figure 4 until the snap-on connection is complete.

[0044] The third clamping component is used to cooperate with the ball head component 3. The second clamping component and the third clamping component are two independent components and do not affect each other. The ball head of the ball head component 3 is clamped and cooperated with the third clamping component. The ball head component 3 can be any component with a ball head structure and is not limited to a ball head screw.

[0045] Compared with the prior art, the ball head seat buckle installation structure provided by the embodiment of the utility model first moves the first clamping member 1 and the ball head seat buckle 2 axially relative to each other to the preparatory position during assembly, and then rotates the two relative to each other at a preset angle at the preparatory position, so that the first clamping structure 120 and the second clamping structure 220 are mutually clamped, and the assembly of the first clamping member 1 and the ball head seat buckle 2 is completed, and finally the ball head member 3 is matched with the third clamping member. Due to the mutual clamping of the first clamping structure 120 and the second clamping structure 220 at this time, the first clamping member 1 and the ball head seat buckle 2 are closely matched and relatively limited, so that the axial directions of the ball head seat buckle 2 and the ball head member 3 are almost parallel and the relative position is easier to control. During the press-fitting process, there will be no sudden position change between the ball head seat buckle 2 and the ball head member 3, so that the ball head seat buckle 2 is not easily crushed, thereby effectively improving the assembly yield. .

[0046] like Figures 7 to 9 As shown, the first clamping member 1 includes a sleeve portion 110, on the inner surface of the sleeve portion 110, a plurality of first clamping structures 120 are arranged circumferentially and spaced apart, and two adjacent first clamping structures 120 are spaced apart to form a first escape space 130, and the first escape space 130 is used for the second clamping structure 220 to pass through, so as to enter the preparation position. Figures 10 to 13 As shown, the second clamping member includes a central portion 210, and a plurality of second clamping structures 220 are arranged circumferentially on the outer surface of the central portion 210 at intervals, and a second avoidance space is correspondingly provided between two adjacent second clamping structures 220 for avoiding the first clamping structure 120, so that the first clamping structure 120 and the second clamping structure 220 can be arranged alternately along the circumferential direction. Based on the above structural setting, in the embodiment of the present application, during assembly, the ball head seat buckle 2 is inserted into the sleeve portion 110 of the first clamping member 1 serving as the dimming bracket. Of course, in other embodiments, the reverse can be applied, so that the second clamping member has the sleeve portion 110, and the first clamping member 1 includes the central portion 210.

[0047] To facilitate the setting of the third clamping component, in the embodiment of the present application, the center portion 210 and / or at least part of the second clamping structure 220 is connected with a clamping ring 250, and the inner surface of the clamping ring 250 is provided with a third clamping component, that is, in the embodiment of the present application, the second clamping component and the third clamping component are coaxially staggered, the second clamping component is clamped and matched with the first clamping component 1 radially outward, and the third clamping structure is clamped and matched with the ball head component 3 radially inward, without interfering with each other.

[0048] Specifically, Fig.10 and Fig.13 As shown, Fig.10 This is a structural schematic diagram of a ball head seat buckle 2 of a ball head seat buckle installation structure provided by an embodiment of the utility model. Fig.13 A bottom view of a ball seat buckle 2 of the ball seat buckle installation structure provided in an embodiment of the utility model.

[0049] The third clamping component includes a plurality of clamping plates 230 arranged at intervals along the circumferential direction, and the clamping plates 230 extend radially along the clamping ring 250. The ends of each clamping plate 230 away from the clamping ring 250 form an accommodating space 240. The diameter of the accommodating space 240 is smaller than the diameter of the ball head of the ball head component 3. The clamping plates 230 can produce a certain degree of elastic deformation. When the ball head component 3 is pressed into the ball head seat buckle 2, each clamping plate 230 is squeezed by the ball head of the ball head component 3 and elastically deforms, so that the diameter of the accommodating space 240 is expanded to allow the ball head of the ball head component 3 to pass through. After the ball head passes through, each clamping plate 230 is no longer squeezed by the ball head, and is reset under the action of its own elasticity. Each clamping plate 230 cooperates with the thinner neck structure behind the ball head of the ball head component 3 to achieve a clamping fit with the ball head component 3.

[0050] Further optimize the above technical solution, such as Figures 10 to 12As shown, in the embodiment of the present application, the clamping plate 230 is tilted along the direction in which the ball head of the ball head component 3 is inserted into the third clamping component, so that each clamping plate 230 forms a funnel-shaped guide structure connected to the accommodating space 240. The funnel-shaped guide structure can guide the ball head of the ball head component 3 to move in the direction of the accommodating space 240, and try to ensure that the ball head can apply the same force to each clamping plate 230, so that the ball head component 3 is easier to match with the third clamping component. At the same time, after the ball head component 3 is matched with the third clamping component, since the tilting direction of each clamping plate 230 is opposite to the direction in which the ball head component 3 is separated from the third clamping component, it can also prevent the ball head component 3 from being separated from the third clamping component, so that the connection between the third clamping component and the ball head component 3 is more stable.

[0051] To facilitate the relative rotation of the first clamping member 1 and the ball head seat buckle 2, as shown in FIG. Figures 10 to 12 As shown, a rotary wrench 270 is provided at one end of the center portion 210 away from the retaining ring 250, and the rotary wrench 270 is used by the assembler to hold the ball head seat buckle 2. The shape of the rotary wrench 270 includes but is not limited to a plate shape, a cross shape, a cylindrical shape, etc., and stripes, concave-convex structures, etc. can be provided on the outer surface of the rotary wrench 270 to increase the friction of the rotary wrench 270.

[0052] Please refer to Figure 7 and Figure 8 , Figure 7 This is a structural schematic diagram of the first clamping member 1 of the ball head seat buckle installation structure provided by the embodiment of the utility model, Figure 8 A top view of the first clamping member 1 of the ball head seat buckle installation structure provided in an embodiment of the utility model.

[0053] One of the first clamping structure 120 and the second clamping structure 220 includes a first limiting portion 121, an intermediate connecting portion 122 and a second limiting portion 123 which are connected in sequence along the circumferential direction. The two circumferentially opposite surfaces of the first limiting portion 121 and the second limiting portion 123 are circumferential stop limit surfaces, and the two circumferential stop limit surfaces are used to limit the second clamping structure 220 in the circumferential direction. The upper and lower surfaces of the intermediate connecting portion 122 are axial stop limit surfaces, and the two axial stop limit surfaces are used to limit the second clamping structure 220 in the axial direction, so that the first clamping structure and the ball head seat buckle 2 remain relatively stable in the axial and circumferential directions.

[0054] The other of the first clamping structure 120 and the second clamping structure 220 includes a clamping portion 221, and a plurality of clamping portions 221 are arranged around the center portion 210 at intervals along the circumferential direction, and the clamping portions 221 extend radially along the radial direction of the center portion 210. A clamping groove 222 is arranged at one end of the clamping portion 221 away from the center portion 210. The clamping portion 221 is provided with a clamping groove 222, and two groove walls of the clamping groove 222 opposite to each other in the axial direction are respectively used to cooperate with two axial stop limit surfaces. In the embodiment of the present application, the other of the first clamping structure 120 and the second clamping structure 220 is a clamping portion 221 with two surfaces opposite to each other in the circumferential direction, which are respectively used to cooperate with two axial stop limit surfaces.

[0055] In the embodiment of the present application, the first clamping structure 120 includes a first limiting portion 121, an intermediate connecting portion 122 and a second limiting portion 123, and the second clamping structure 220 includes a clamping portion 221 having a clamping slot 222. Of course, it should be noted that in other embodiments, the first clamping structure 120 can include a clamping portion 221 having a clamping slot 222, and the second clamping structure 220 can include a first limiting portion 121, an intermediate connecting portion 122 and a second limiting portion 123.

[0056] In order to improve the strength of each clamping part 221 and reduce the deformation of the clamping part 221 during the assembly process, in an embodiment of the present application, each clamping part 221 is connected as a whole through a clamping ring 250. This can ensure that the clamping part 221 will not be excessively deformed during the assembly process, thereby avoiding the clamping part 221 from breaking.

[0057] To further optimize the above technical solution, in one embodiment of the present application, Figures 10 to 12 As shown, one axial end face of the above-mentioned retaining ring 250 is flush with one of the two axially opposite groove walls of the retaining groove 222, and a limiting boss 260 is provided between two circumferentially adjacent clamping portions 221 on the axial end face of the retaining ring 250 that is flush with the groove wall of the retaining groove 222. The other of the two axially opposite groove walls of the retaining groove 222 and the limiting bosses 260 on both sides form a clamping space that cooperates with the first limiting portion 121, the middle connecting portion 122 and the second limiting portion 123.

[0058] like Figure 7 and Figure 8As shown, a first guide surface is provided at one end of the first limiting portion 121 away from the second limiting portion 123, and the first guide surface causes the axial dimension of the first limiting portion 121 to gradually increase from the end away from the second limiting portion 123, and the minimum axial dimension of the first limiting portion 121 is smaller than the gap between the two axially opposite surfaces of the slot 222; and / or, a second guide surface is provided at one end of the second limiting portion 123 away from the first limiting portion 121, and the second guide surface causes the axial dimension of the second limiting portion 123 to gradually increase from the end away from the first limiting portion 121, and the minimum axial dimension of the second limiting portion 123 is smaller than the gap between the two axially opposite surfaces of the slot 222.

[0059] It should be noted that the first position limiting portion 121 and the second position limiting portion 123 may adopt the same structure, the same structure, or different structures. In one embodiment of the present application, the first position limiting portion 121 and the second position limiting portion 123 are two different structures, that is, only the first position limiting portion 121 is provided with a first guide surface, and the height of the circumferential stop-rotation limit surface of the first position limiting portion 121 is smaller than the height of the circumferential stop-rotation limit surface of the second position limiting portion 123, so that the clamping portion 221 of the second clamping structure 220 can only cooperate with the first clamping structure 120 from one side of the first position limiting portion 121.

[0060] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0061] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
