Detailed implementation manners

[0035] One of the cores of the present utility model is to provide a threaded fastener installation structure. The structural design of this threaded fastener installation structure enables it to meet the installation requirements of multiple hole pitch installation platforms, reduce repetitive development work, reduce the types of products, thereby increasing the demand for a single product and reducing product costs.

[0036] Another core of the present utility model is to provide a radiator adopting the above-mentioned threaded fastener installation structure.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0038] Please refer to Figures 1 to 5 , Figure 1 which is a top view of the base body of the threaded fastener installation structure provided by an embodiment of the present utility model, Figure 2 which is a partial structural schematic diagram of the base body of the threaded fastener installation structure provided by an embodiment of the present utility model, Figure 3 which is a structural schematic diagram of the threaded fastener of the threaded fastener installation structure provided by an embodiment of the present utility model, Figure 4 which is an exploded view of the threaded fastener installation structure provided by an embodiment of the present utility model, Figure 5 which is a cross-sectional view of the threaded fastener installation structure provided by an embodiment of the present utility model when in the first installation position.

[0039] An embodiment of the present utility model discloses a threaded fastener installation structure, which includes a base body 1, a threaded fastener 3, and an elastic member 4.

[0040] Among them, the base body 1 is provided with an installation structure 2 penetrating the base body 1. The installation structure 2 includes at least two installation holes 210 and a channel 220 connecting the installation holes 210 in sequence. The diameter of the installation hole 210 is D1, and the width of the channel 220 is D2. The width D2 of the channel 220 is less than the diameter D1 of the installation hole 210. During the design process, the hole pitch can be adjusted by adjusting the length and shape of the channel 220. When the installation structure 2 includes three or more installation holes 210, along the arrangement direction, the axial pitch between adjacent two installation holes 210 can be the same or different.

[0041] The threaded fastener 3 includes a rod portion 310 and a nut connected to one end of the rod portion 310. The rod portion 310 is sequentially provided with a threaded portion 311, a first mating portion 312, and a second mating portion 313 starting from the end away from the nut. The diameter of the first mating portion 312 is greater than the diameter of the second mating portion 313 and the width of the channel 220. The first mating portion 312 is adapted to the mounting hole 210. The first mating portion 312 being adapted to the mounting hole 210 means that the diameter d1 of the first mating portion 312 is less than or equal to the diameter D1 of the mounting hole 210. The second mating portion 313 is adapted to the channel 220. The second mating portion 313 being adapted to the channel 220 means that the diameter d2 of the second mating portion 313 is less than or equal to the width D2 of the channel 220. In this way, the second mating portion 313 can slide from one mounting hole 210 along the channel 220 into another mounting hole 210.

[0042] The elastic member 4 is disposed between the nut and the base body 1. The elastic member 4 includes, but is not limited to, a cylindrical helical spring, a conical spring, a plate spring, a torsion spring, etc. Of course, it is not limited to the above several types. The elastic member 4 can also be other parts that deform after an external force is applied and return to their original state after the external force is removed, which is not limited here.

[0043] In the initial state, the threaded fastener 3 is inserted through one of the mounting holes 210 of the mounting structure 2, and under the action of the elastic member 4, the first mating portion 312 is engaged with one of the mounting holes 210, as Figure 5 shown. At this time, since the diameter of the first mating portion 312 is greater than the width of the channel 220, the threaded fastener 3 cannot enter another mounting hole 210 through the channel 220. When it is necessary to adjust the position of the threaded fastener 3, pressure is applied to the nut of the threaded fastener 3 to make the nut move towards the base body 1 against the elastic force of the elastic member 4 until the second mating portion 313 enters the mounting hole 210. At this time, since the second mating portion 313 is adapted to the channel 220, the second mating portion 313 can leave one of the mounting holes 210, as Figure 6 shown, and slide along the channel 220 into another mounting hole 210. After the threaded fastener 3 moves into place, the nut is released, and under the action of the elastic member 4, the threaded fastener 3 resets, and the first mating portion 312 is engaged with another mounting hole 210, as Figure 7 shown, realizing the limitation of the threaded fastener 3.

[0044] Compared with the prior art, the installation structure 2 of the threaded fastener 3 provided by the embodiment of the present utility model can adjust the installation position of the threaded fastener 3, thereby changing the spacing between two adjacent threaded fasteners 3. And during the adjustment process, no tools are required, and no components need to be removed or replaced. It can be adjusted at the work site, which is very flexible. Moreover, through the design of the relative positions of multiple mounting holes 210, precise control of the spacing of the threaded fasteners 3 can be achieved. And the installation structure 2 of the threaded fastener 3 is simple, without adding any special processing techniques, with low cost, can realize the sharing of products with different hole spacings, greatly improve the design reusability, reduce the types of products, increase the demand for a single product, and reduce the product cost.

[0045] To prevent the threaded fastener 3, the elastic member 4, etc. from falling off the base body 1 during production, transportation, and installation, as Figures 3 to 5 shown, in an embodiment of the present application, the installation structure 2 of the threaded fastener 3 further includes a limit retaining ring 5. A clamping groove 315 is provided on the first mating portion 312. The limit retaining ring 5 is clamped and fitted with the clamping groove 315 from the side of the base body 1 away from the nut. The diameter of the retaining ring is larger than the diameter of the mounting hole 210. The limit retaining ring 5 cooperates with the nut and the elastic member 4, which can limit the threaded fastener 3 while ensuring that the threaded fastener 3 can reciprocate along its own axis relative to the base body 1, so as to prevent the threaded fastener 3 from detaching from the base body 1, thus achieving the effect of preventing the loss of the threaded fastener 3. And because the installation structure 2 of the threaded fastener 3 provided by the present application does not require the threaded fastener 3 to be removed from the base body 1 when adjusting the position of the threaded fastener 3, the limit retaining ring 5 basically does not need to be disassembled and replaced during use. Specifically, the above-mentioned limit retaining ring 5 is Figure 4 the snap ring shown, or the circumferentially closed O-ring.

[0046] As Figure 3 shown, in an embodiment of the present application, the rod portion 310 further includes a third mating portion 314 connecting the second mating portion 313 and the nut. The diameter of the third mating portion 314 is larger than the diameter of the second mating portion 313. The diameter of the third mating portion 314 can be equal to or different from the diameter of the first mating portion 312. In the Figure 3 shown embodiment, the diameter of the first mating portion 312 is equal to the diameter of the third mating portion 314. The third mating portion 314 can be used to guide and limit the elastic member 4 during the compression process.

[0047] It can be seen from the above description that when the user releases the nut, it is required that the threaded fastener 3 makes the first mating portion 312 re-enter the mounting hole 210 under the action of the elastic member 4. And since the diameters of the first mating portion 312 and the second mating portion 313 are different, a stepped structure will be formed between the two, and this stepped structure may interfere with the base body 1 and thus affect the reset of the threaded fastener 3. Therefore, in an embodiment of the present application, asFigure 3 As shown, a conical guiding portion is provided between the first engaging portion 312 and the second engaging portion 313. The cross-section of the conical guiding portion gradually expands in the direction from the second engaging portion 313 to the first engaging portion 312. That is, the stepped structure between the first engaging portion 312 and the second engaging portion 313 is processed into a conical guiding portion, so as to ensure that the threaded fastener 3 can be reset smoothly and avoid jamming.

[0048] The installation structure 2 can adopt various structures according to the hole pitch requirements, such as Figure 2 As shown, in an embodiment of the present application, the axial distance between two adjacent mounting holes 210 of the mounting structure 2 is less than the diameter of the mounting hole 210. That is, the shape of the cross-section of the mounting structure 2 perpendicular to the axis of the mounting hole 210 is the shape of two intersecting circles. This structure makes the length of the channel 220 shorter and is suitable for the case where the difference in the two hole pitches is not large, such as Figure 1 In the shown embodiment, the base body 1 is a rectangular structure, and the center connection line of the two mounting holes 210 of the mounting structure 2 is arranged along the diagonal of the base body 1. Of course, it should be noted that the center connection line of the mounting holes 210 of the mounting structure 2 does not necessarily have to be arranged along the diagonal of the base body 1 and needs to be adjusted according to the center distance of the mounting holes 210 and the required hole pitch, which is not limited here. Figure 1 In the first direction (the left-right direction in the figure), the hole pitch of one of the mounting holes 210 is W1, and the hole pitch of the other mounting hole 210 is W2. In the second direction (the up-down direction in the figure), the hole pitch of one of the mounting holes 210 is L1, and the hole pitch of the other mounting hole 210 is L2.

[0049] Of course, in order to provide two hole pitches with a large difference, it can be achieved by increasing the length of the channel 220, that is, as Figure 8 shown, the axial distance between two adjacent mounting holes 210 of the mounting structure 2 is greater than the diameter of the mounting hole 210.

[0050] To further optimize the above technical solution, as Figure 9 shown, the axial distance between at least two adjacent mounting holes 210 of the mounting structure 2 is less than the diameter of the mounting hole 210, and the axial distance between the remaining adjacent mounting holes 210 is greater than the diameter of the mounting hole 210. That is, when the mounting structure 2 includes 3 or more mounting holes 210, the axial distances between the respective mounting holes 210 can be different, and the axes of the respective mounting holes 210 can be on the same straight line or not on the same straight line.

[0051] In the embodiment of the present application, the above channel 220 can be as Figure 2 and Figure 8The straight channel 220 shown may also be a curved channel 220, such as an arc-shaped channel 220 or a combined channel 220 formed by connecting multiple arc-shaped channels 220 with different diameters and smooth connections, or it may also be, for example, Figure 9 a combined channel 220 formed by connecting the straight channel 220 and the curved channel 220 as shown.

[0052] For example, Figure 4 and Figure 5 As shown, in an embodiment of the present application, the elastic member 4 is a cylindrical helical spring. To prevent the two ends of the cylindrical helical spring from moving radially during compression or extension, resulting in the distortion of the cylindrical helical spring, in an embodiment of the present application, a first limiting groove adapted to the outer diameter of the cylindrical helical spring is provided on the surface of the base 1 facing the nut side. The first limiting groove is arranged around the mounting structure 2, and the limiting groove is used to limit the elastic member 4, and / or, a limiting boss adapted to the inner diameter of the cylindrical helical spring is provided on the surface of the nut facing the base 1, or a second limiting groove adapted to the outer diameter of the cylindrical helical spring is provided.

[0053] Please refer to Figure 10 , Figure 10 which is a schematic structural diagram of the radiator provided by the embodiment of the present invention. In an embodiment of the present application, a radiator is provided. The radiator includes a substrate and heat dissipation fins 6 arranged on the substrate, and the radiator also adopts the threaded fastener 3 mounting structure 2 as described in the above embodiment. The substrate serves as the base 1 of the threaded fastener 3 mounting structure 2. Since the radiator adopts the threaded fastener 3 mounting structure 2 in the above embodiment, the technical effects of the radiator can be referred to the above embodiment. It should be noted that the radiator with the above threaded fastener 3 mounting structure 2 is only a preferred application solution provided by the present application. In fact, the threaded fastener 3 mounting structure 2 is not limited to being applied to the radiator, and can also be applied to the installation of other devices with the need to adjust the hole spacing.

[0054] It should be noted that the embodiments in this specification are all described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0055] Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The descriptions of the above embodiments are only used to help understand the core idea of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
