Detailed Description

Various embodiments of the present invention are described below with reference to the accompanying drawings, which form a part hereof. It should be understood that the same or similar reference numerals are used throughout this disclosure to designate the same components as possible.

Fig. 1 shows a perspective structural view of a first embodiment of a fastening assembly in a fastened state according to the present invention, and fig. 2 shows an exploded view of fig. 1.

As shown in fig. 1-2, the cylindrical part 13 is secured by the fastening assembly 10 into an opening 121 formed in the base plate 12. The fastening assembly 10 includes a clip assembly 11, the clip assembly 11 being provided with a first clip 14 and a second clip 15 in a circumferential direction, the first clip 14 and the second clip 15 partially surrounding the cylindrical part 13. The inside of the clip assembly 11 (i.e., the first clip 14 and the second clip 15) encloses at least a portion of the cylindrical surface of the cylindrical part 13. The inside of the clip assembly 11 of the fastening assembly 10 includes an accommodation space 111 for accommodating the cylindrical part 13. The outer side surface of the first clip 14 is provided with a mounting space 143 for receiving a portion of the substrate 12 near the opening 121, thereby preventing the first clip 14 from moving in the axial direction of the opening 121. The first clip 14 is divided into an upper portion 141 and a lower portion 142 in the axial direction, and a mounting space 143 is disposed between the upper portion 141 and the lower portion 142 (see fig. 3A to 3F). The mounting space 143 has a height H for being able to accommodate the thickness D of the substrate 12. The second clip 15 of the clip assembly 11 is a mirror image of the first clip 14. In other embodiments, the second clip 15 may be a different structure than the first clip 14 (see fig. 14 and 15A-15B). Also, the clip assembly 11 may not have the second clip 15 (see fig. 16A-16B).

The size of the receiving space 111 inside the first and second clips 14 and 15 can be adjusted by adjusting the positions of the first and second clips 14 and 15, thereby enabling the clip assembly 11 to fix the cylindrical part 13 into the opening 121 of the base plate 12. The outer surface of the cylindrical part 13 shown in fig. 1-2 is cylindrical. In other embodiments, the cylindrical part 13 has other suitable profiles.

The fastening assembly 10 also includes a securing structure for maintaining the position of the clip assembly 11. For example, the fixing structure is used to keep the relative positions of one end of the first clip 14 and one end of the second clip 15 unchanged. When the clip assembly 11 secures the cylindrical part 13 in the opening 121 of the base plate 12, the securing structure serves to hold the clip assembly 11 in this secured position without loosening, thereby preventing the cylindrical part 13 from coming out of the opening 121 of the base plate 12. As shown in fig. 1-2, the securing structure of the first embodiment includes fasteners, such as screws 161 and nuts 162, for connecting one end of the first clip 14 and one end of the second clip 15 together to maintain the relative position. In other embodiments, the securing structure may include other forms of structure (see fig. 6A-6B, 7A-7C, and 11C-11D).

In one embodiment, in operation, the first clip 14 is inserted into the opening 121 of the base plate 12 and moved radially toward the opening 121 such that the mounting space 143 of the first clip 14 accommodates the base plate 12, i.e., the upper portion 141 and the lower portion 142 of the first clip 14 sandwich the base plate 12, such that the first clip 14 does not disengage from the base plate 12 in the axial direction of the opening 121 and the cylindrical part 13 cannot be fixed to the base plate 12 by the first clip 14. Similarly, the second clip 15 is mounted to the base plate 12, and then the cylindrical part 13 is inserted into the receiving space 111 of the inside of the clip assembly 11. Then, the screw 161 and the nut 162 are mounted to one end of the first clip 14 and one end of the second clip 15, and the first clip 14 and the second clip 15 of the clip assembly 11 are moved toward each other by tightening the screw 161 and the nut 162 so that the receiving space 111 of the inner sides of the first clip 14 and the second clip 15 becomes gradually smaller, and finally the first clip 14 and the second clip 15 fix the cylindrical part 13 into the opening 121 of the base plate 12. In the process of tightening the screw 161 and the nut 162 to bring the first clip 14 and the second clip 15 of the clip assembly 11 toward each other, the installation space 143 of the first clip 14 and the second clip 15 always accommodates the base plate 12 without disengaging the first clip 14 from the base plate 12 in the axial direction of the opening 121, thereby resulting in failure of fixing the cylindrical part 13 to the base plate 12 by the first clip 14. When the cylindrical part 13 is fixed into the opening 121 of the base plate 12, the tightening of the screw 161 and the nut 162 simultaneously keeps the first clip 14 and the second clip 15 of the clip assembly 11 in the tightened position without loosening, thereby keeping the cylindrical part 13 fixed to the base plate 12. In other embodiments, the various components described above may be assembled in other suitable sequences to secure the cylindrical part 13 into the opening 121 of the base plate 12.

The substrate may be a substrate made of plastic, metal, or the like, for example, a galvanized steel sheet, a PCB board. The clips of the present invention may be made of a suitable material, such as plastic, metal, etc., for engagement with the base plate to thereby secure the columnar elements to the base plate.

Fig. 3A illustrates a perspective view of a first embodiment of the clip of the fastening assembly of fig. 2, fig. 3B illustrates a perspective view of the clip of fig. 3A at another angle, fig. 3C illustrates a perspective view of a portion (with an upper portion removed) of the clip of fig. 3A, fig. 3D illustrates a top view of fig. 3C, and fig. 3E-3F illustrate left and right views, respectively, of the clip of fig. 3A.

For the sake of simplicity, fig. 3A-3F only show a schematic structural view of the first clip 14 in the clip assembly 11 of the fastening assembly 10. As shown in fig. 3A-3F, the first clip 14 includes an upper portion 141, a lower portion 142, and a wedge member 144 positioned between the upper portion 141 and the lower portion 142. The outer side surface of the first clip 14 is provided with a mounting space 143, and the mounting space 143 is disposed between the upper portion 141 and the lower portion 142. The mounting space 143 is used for enabling the first clamp 14 to clamp the edge of the opening 121 of the base plate 12, so that the base plate 12 and the clamp assembly 11 cannot move relatively along the axial direction of the opening 121, and the purpose of fixing the cylindrical part 13 in the opening 121 of the base plate 12 can be achieved. The height H of the mounting space 143 is greater than or equal to the thickness D of the substrate 12, so that the mounting space 143 can accommodate the substrate 12. At least one wedge member 144 is provided in the mounting space 143 of the first clip 14. By way of example, fig. 3C-3D show four wedge members 144 disposed in wedge space 143. The first clip 14 may be integrally formed or may be formed in other suitable manners.

The upper portion 141 of the first clip 14 includes a baffle member 1410 that includes a base plate 1411, an arcuate portion 1412, and a rib 1413, the arcuate portion 1412 being disposed perpendicular to the base plate 1411 and being "L" shaped. The rib 1413 is generally right triangular in shape with generally perpendicular sides connected to the arcuate portion 1412 and the base 1411, respectively, and neither of these sides has a length that exceeds the width of the arcuate portion 1412 and the base 1411. The rib 1413 increases the rigidity of the arcuate portion 1412 and the bottom 1411 of the upper portion 141 of the first clip 14, making the structure of the upper portion 141 more rigid. One end of the upper portion 141 is also provided with a mounting structure 1414 for mounting the screw 161 and nut 162. The mounting structure 1414 includes an upper side plate 1415 and a lower side plate 1416 disposed parallel to each other, and an intermediate plate 1417 disposed substantially perpendicular to the upper side plate 1415 and the lower side plate 1416. The lower side plate 1416 is part of the bottom plate 1411, and the upper side plate 1415 is flush with the top of the arcuate portion 1412 and is connected to the arcuate portion 1412. The intermediate plate 1417 includes holes 1418, wherein screws 161 can be inserted through the holes 1418 to mate with nuts 162 for tightening. The second clip 15 in the clip assembly 11 may be of the same construction as the first clip 14. As shown in fig. 1-2, the screw 161 may pass through a hole 1418 on one end of the upper portion 141 of the first clip 14 and a hole on one end of the corresponding upper portion of the second clip 15, and the nut 162 is mounted to the screw 161 from the end of the screw 161, and by tightening the screw 161 and the nut 162, one end of the first clip 14 and one end of the second clip 15 are brought close together and connected together. In other embodiments, the upper portion 141 of the first clip 14 may include other suitable structures, such as for mounting screws 161 and nuts 162, for making the structure stronger, and so forth.

The lower portion 142 of the first clip 14 is a mirror image of the upper portion 141. Specifically, the lower portion 142 of the first clip 14 includes a baffle member 1420 disposed parallel to the baffle member 1410 of the upper portion 141, the baffle member 1420 including a floor 1421, an arcuate portion 1422, a rib 1423, and a mounting structure 1424. The screw 161 and nut 162 may be mounted to the mounting structure 1414 of the upper portion 141 only, to the mounting structure 1424 of the lower portion 142 only, or to both the upper portion 141 and the lower portion 142.

The wedge member 144 is located between the bottom plate 1411 of the upper portion 141 and the bottom plate 1421 of the lower portion 142 and the top and bottom surfaces of the wedge member 144 are connected to the two bottom plates 1411, 1421, respectively. In one embodiment, the two bottom plates 1411, 1421 are disposed in parallel. As shown in fig. 3C-3D, the wedge member 144 has an arcuate pressing surface 140, the wedge member 144 further including a tail 145 and a head 146, the radius of the arcuate pressing surface 140 increasing from the tail 145 to the head 146 of the wedge member 144. The wedge member 144 has a height H, which defines a height H of the installation space 143. The wedge member 144 also has an inner surface that is on the same arcuate surface as the inner surfaces of the upper portion 141 and lower portion 142 of the first clip 14 (i.e., the inner surfaces of the arcuate portions 1412, 1422). The floor 1411 of the upper portion 141 and the floor 1421 of the lower portion 142 extend radially beyond the wedge members 144. Accordingly, when the mounting space 143 accommodates the substrate 12, the portions of the bottom plate 1411 of the upper portion 141 and the bottom plate 1421 of the lower portion 142 that protrude beyond the wedge members 144 can prevent the first clip 14 from moving in the axial direction of the opening 121.

In other embodiments, the wedge member 144 may include other suitable structures, such as providing a groove on an outer surface of the wedge portion to form the wedge member (see fig. 9A-9C and 12A-12C), the wedge member being formed from portions of the wedge portion (see fig. 10A-10C and 13A-13C).

As shown in fig. 1-2 and 3A-3D, the wedge member 144 of the first clip 14 is configured to engage the edge 122 of the opening 121 of the substrate 12, and the edge 122 of the opening 121 is provided with a first wedge surface 147 (see fig. 4B and 5B-5C) that mates with the outer surface (i.e., the arcuate pressing surface 140) of the wedge member 144 of the first clip 14. When the first clamp 14 is rotated in its preset locking direction (i.e., counterclockwise), the first wedge surface 147 of the base plate 12 can exert a radial force against the arcuate pressing surface 140 of the wedge member 144 of the first clamp 14, thereby pushing the first clamp 14 toward the center of the opening 121, thereby allowing the clamp assembly 11 to secure the cylindrical part 13 into the opening 121 of the base plate 12. Similarly, the edge 122 of the opening 121 is also provided with a second wedge surface 148 (see fig. 4B, 5B and 5C) that mates with the outer surface of the wedge member 154 (i.e., the arcuate pressing surface 150) of the second clip 15, the wedge member 154 of the second clip 15 and the second wedge surface 148 on the edge 122 of the opening 121 cooperating similarly as the wedge member 144 and the first wedge surface 147.

In other embodiments, the first clip 14 and the second clip 15 include other suitable forms of structure to form wedge members thereof and corresponding mounting spaces (see fig. 8, 9A-9C, and 10A-10C).

Fig. 4A shows a top view of the fastening assembly of fig. 1 in an initial state, and fig. 4B shows a cross-sectional view of fig. 4A. The cross-sectional view in fig. 4B is a cross-sectional view taken along a plane perpendicular to the axial direction of the cylindrical part, the plane being transverse to the wedge-shaped members in the clip assembly of the fastening assembly. Fig. 5A shows a top view of the fastening assembly of fig. 1 in a fastened state, fig. 5B shows a cross-sectional view taken along a section line A-A of fig. 1, and fig. 5C shows a partially enlarged view of fig. 5B.

As shown in fig. 4B and 5B, the arcuate pressing surface 140 of the wedge member 144 of the first clip 14 mates with the first wedge surface 147 of the edge 122 of the opening 121 and is adapted to engage the first wedge surface 147. The radius of the arcuate pressing surface 140 increases from the tail 145 to the head 146 of the wedge member 144. The radial width of the wedge member 144 becomes progressively greater from the tail 145 to the head 146 of the wedge member 144. The first wedge-face 147 includes a head end 1471 and a tail end 1472, with the radius of the first wedge-face 147 (e.g., from the first wedge-face 147 to the center of the opening 121) increasing from the tail end 1472 to the head end 1471. Similar to the first clip 14, the second clip 15 includes a wedge member 154 having an arcuate pressure applying surface 150. The arcuate pressing surface 150 mates with the second wedge surface 148 of the edge 122 of the opening 121 and is adapted to engage the second wedge surface 148. Second wedge face 148 includes a head end 1481 and a tail end 1482, with the radius of second wedge face 148 (e.g., from second wedge face 148 to the center of opening 121) becoming progressively larger from tail end 1482 to head end 1481.

As shown in fig. 4A to 4B, the fastening assembly 10 is in an initial state, one end of the first clip 14 and one end of the second clip 15 of the clip assembly 11 of the fastening assembly 10 are spaced farther from each other, and the screw 161 and the nut 162 of the fastening assembly 10 are also spaced farther from each other. At this time, the wedge member 144 of the first clip 14 is positioned near the head end 1471 of the first wedge surface 147, and the wedge member 154 of the second clip 15 is positioned near the head end 1481 of the second wedge surface 148, so that the receiving spaces 111 inside the first clip 14 and the second clip 15 are sufficiently large, and the cylindrical part 13 can be moved inside the clip assembly 11 to adjust the position.

In an initial state as shown in fig. 4A to 4B, when the screw 161 and the nut 162 are tightened toward each other to approach one end of the first clip 14 and one end of the second clip 15 toward each other, the first clip 14 is rotated in its preset locking direction (i.e., counterclockwise) and the second clip 15 is rotated in its preset locking direction (i.e., clockwise), and at this time the first wedge surface 147 of the opening 121 can apply a radial force to the arc-shaped pressing surface 140 of the wedge member 144 of the first clip 14 and the arc-shaped pressing surface 150 of the wedge member 154 of the second clip 15, so that the accommodation space 111 inside the first clip 14 and the second clip 15 becomes gradually smaller. Finally, the receiving space 111 inside the first clip 14 and the second clip 15 is minimized so that the fastening assembly 10 reaches the fastened state as shown in fig. 5A to 5B, when the wedge member 144 of the first clip 14 moves from a position near the head end 1471 of the first wedge-shaped surface 147 of the opening 121 (see fig. 4B) to a position near the tail end 1472 of the first wedge-shaped surface 147 (see fig. 5B to 5C), and the wedge member 154 of the second clip 15 moves from a position near the head end 1481 of the second wedge-shaped surface 148 of the opening 121 (see fig. 4B) to a position near the tail end 1482 of the second wedge-shaped surface 148 (see fig. 5B to 5C). In the fastened state shown in fig. 5A-5B, the first wedge surface 147 of the opening 121 secures the first clip 14 against the cylindrical part 13, and the second wedge surface 148 of the opening 121 secures the second clip 15 against the cylindrical part 13, such that the first clip 14 and the second clip 15 secure the cylindrical part 13 to the base plate 12.

In the fastened state shown in fig. 5A to 5B, when the fastening of the screw 161 and the nut 162 is released, the first clip 14 is rotated in a direction opposite to its preset locking direction (i.e., clockwise direction) and the second clip 15 is rotated in a direction opposite to its preset locking direction (i.e., counterclockwise direction), at which time the receiving spaces 111 inside the first clip 14 and the second clip 15 become gradually larger, for example, return to the initial state shown in fig. 4A to 4B, so that the clip assembly 11 enables the cylindrical part 13 to be separated from the base plate 12.

The screw 161 and the nut 162 also serve as fixing structures of the first embodiment for maintaining the positions of the first clip 14 and the second clip 15 of the clip assembly 11. When the first clip 14 and the second clip 15 are rotated from the initial position shown in fig. 4A to 4B to the fastened position shown in fig. 5B to 5C by tightening the screw 161 and the nut 162, the fastening of the screw 161 and the nut 162 to each other also keeps the first clip 14 and the second clip 15 at the fastened position without loosening, thereby preventing the first clip 14 and the second clip 1 from moving toward the initial position, and further keeps the cylindrical part 13 fastened to the opening 121 of the base plate 12 without loosening.

The fixing structure of the present invention also includes other embodiments such as a second embodiment fixing structure (see fig. 6A and 11C), a third embodiment fixing structure (see fig. 6B and 11D), and a fourth embodiment fixing structure (see fig. 7A to 7C) which are shown in detail below. As described in detail below, the securing structures of the second and third embodiments include a first ratchet tooth provided on the wedge-shaped member of the clip and a second ratchet tooth provided on the edge of the opening, the second ratchet tooth cooperating with the first ratchet tooth to limit rotation of the clip in a direction opposite the locking direction. The fixing structure of the fourth embodiment includes a first helical tooth provided on an end portion of the first clip and a second helical tooth provided on an end portion of the second clip, the second helical tooth and the first helical tooth being engaged with each other to restrict reverse rotation of the first clip and the second clip in a locking direction.

Fig. 6A shows a cross-sectional view of the fastening assembly of fig. 5C including the fixing structure of the second embodiment, and fig. 6B shows a cross-sectional view of the fastening assembly of fig. 5C including the fixing structure of the third embodiment. As shown in fig. 1 to 2, the fixing structure of the first embodiment includes a screw 161 and a nut 162.

The securing structure of the second embodiment shown in fig. 6A includes a first ratchet 17 disposed on the wedge member 144 of the first clip 14 and a corresponding second ratchet 18 disposed on the edge 122 of the opening 121. Similarly, the securing structure also includes a third ratchet tooth disposed on the wedge member 154 of the second clip 15 and a corresponding fourth ratchet tooth disposed on the edge 122 of the opening 121. More specifically, the first ratchet 17 is disposed on the arcuate pressing surface 140 of the wedge member 144 and the second ratchet 18 is disposed on the first wedge surface 147 on the edge 122 of the opening 121. A third ratchet tooth is provided on the arcuate pressing surface 150 of the wedge member 154 and a fourth ratchet tooth is provided on the second wedge surface 148 on the edge 122 of the opening 121.

As shown in fig. 6A, the respective teeth of the first ratchet 17 and the respective teeth of the second ratchet 18 are the same in number and cooperate with each other to restrict rotation of the first clip 14 in a direction opposite to the locking direction thereof, so that, for example, the first clip 14 can be held in its fastened position without being released. The tips of the respective teeth of the second ratchet 18 on the opening 121 are configured to restrict (prevent) the first clip 14 from rotating in a direction opposite to the locking direction thereof (i.e., clockwise direction), for example, the respective teeth of the second ratchet 18 are disposed to be inclined toward the locking direction of the first clip 14. The teeth of the second ratchet 18 are configured such that the teeth of the first ratchet 17 on the first clamp 14 are able to move past the teeth of the second ratchet 18 when the first clamp 14 is rotated in a locking direction therewith. The tips of the respective teeth of the fourth ratchet on the opening 121 are configured to restrict (prevent) the second clip 15 from rotating in a direction opposite to the locking direction thereof (i.e., counterclockwise), for example, the respective teeth of the fourth ratchet are disposed to be inclined toward the locking direction of the second clip 15. The teeth of the fourth ratchet are configured such that the teeth of the third ratchet on the second clamp 15 are able to move past the teeth of the fourth ratchet when the second clamp 15 is rotated in a locking direction therewith.

The fixing structure of the third embodiment shown in fig. 6B is similar to that of the second embodiment shown in fig. 6A. Unlike fig. 6A, in fig. 6B, the second ratchet teeth 19 on the opening 121 have one tooth 191, and a slit 192 is further provided on the base plate 12 from the front end of the tooth 191 toward the rear end of the tooth 191. When the first clamp 14 is rotated in the locking direction, the first ratchet teeth 17 on the first clamp 14 push the teeth 191 of the second ratchet teeth 19 on the opening 121 to bend toward the slit 192, so that the force applied to the teeth 191 by the first ratchet teeth 17 is relieved, and damage to the teeth 191 is avoided. The teeth 191 are elongated. Correspondingly, the fourth ratchet on the opening 121 has a similar structure to the second ratchet 19. The first ratchet 17 on the first clip 14 shown in fig. 6B is identical to the first ratchet 17 shown in fig. 6A. The tips of the teeth 191 of the second ratchet teeth 19 on the opening 121 are configured to restrict (prevent) the first clip 14 from rotating in a direction opposite to the locking direction thereof (i.e., clockwise direction), for example, the teeth 191 of the second ratchet teeth 19 are disposed to be inclined toward the locking direction of the first clip 14. The teeth 191 of the second ratchet teeth 19 are configured such that each tooth of the first ratchet teeth 17 on the first clamp 14 can move past the teeth 191 of the second ratchet teeth 19 when the first clamp 14 is rotated in a locking direction therewith.

When the fixing structure (including the first ratchet and the second ratchet) in fig. 6A to 6B is substituted for the fixing structure (including the screw and the nut) in fig. 1 to 2, the first clip 14 and the second clip 15 do not need to be provided with the mounting structure for mounting the screw and the nut as shown in fig. 3A and 3C, and may be provided with, for example, no rib and no arc. In one embodiment, the first clip 14 and the second clip 15 may comprise only two mutually parallel bottom plates and a wedge-shaped member between the bottom plates, with corresponding ratchet teeth provided on the edges of the wedge-shaped member and the opening to maintain the position of the clips and thereby the cylindrical part in the opening of the base plate.

In operation, an external force is applied to the first and second clips 14, 15 to rotate the first and second clips 14, 15 in their respective locking directions, and the first and second clips 14, 15 are rotated to a fastening position (see fig. 5B) to secure the cylindrical part 13 to the base plate 12. When the first and second clips 14, 15 are rotated to the secured position, the first clip 14 is restrained from rotating in a direction opposite to its locking direction (i.e., clockwise) and the second clip 15 is restrained from rotating in a direction opposite to its locking direction (i.e., counterclockwise) by the engagement of the first ratchet teeth 17 on the first clip 14 with the second ratchet teeth 18, 19 on the opening 121 and the engagement of the third ratchet teeth on the second clip 15 with the fourth ratchet teeth on the opening 121, thereby holding the first clip 14 and the second clip 15 in the secured position and thereby holding the cylindrical part 13 secured to the base plate 12.

Fig. 7A is a perspective view showing a fastening assembly including a fixing structure of a fourth embodiment in a fastened state according to the present invention, fig. 7B is an exploded view of fig. 7A, and fig. 7C is a sectional view taken along a sectional line B-B of fig. 7A. As shown in fig. 1 to 2, the fixing structure of the first embodiment includes a screw 161 and a nut 162.

The securing structure of the fourth embodiment shown in fig. 7A-7C includes a helical tooth 166 disposed on one end of the first clip 14 and a helical rack 165 disposed on one end of the second clip 15. The helical gear 166 and the helical rack 165 are configured to cooperate to limit rotation of the first and second clips 14, 15 in a direction opposite to the locking direction, thereby enabling the relative positions of one end of the first clip 14 and one end of the second clip 15 to be maintained. The diagonal teeth 166 and diagonal racks 165 are also configured to enable the first and second clips 14, 15 to rotate in a locking direction.

A mounting structure 167 for mounting the diagonal rack 165 is provided on one end of the first clip 14 in fig. 7A-7C, which is similar to the mounting structure 1414 for mounting the screw 161 on one end of the first clip 14 in fig. 3A-3F, except that a hole 169 in the mounting structure 167 is provided to enable the diagonal rack 165 of the second clip 15 to be inserted therethrough. In fig. 7A-7C, a mounting structure 168 is provided on one end of the second clip 15, which is similar to the mounting structure 167 on one end of the first clip 14, except that the diagonal rack 165 of the second clip 15 is connected to an intermediate plate 1681 of the mounting structure 168. The diagonal rack 165 may be integrally formed with the mounting structure 168.

As shown in fig. 7C, the diagonal teeth 166 on the first clip 14 include a first base 1661 and a first diagonal tooth 163, the first base 1661 being coupled to the intermediate plate 1671 of the mounting structure 167 to define a channel 1662 through which the diagonal rack 165 can pass. The first beveled tooth 163 extends from the first base 1661 toward the channel 1662 such that the tip of the first beveled tooth 163 is located within the channel 1662. The diagonal rack 165 on the mounting structure 168 of the second clip 15 includes a plurality of second diagonal teeth 164 and a second base 1651 coupled to the plurality of second diagonal teeth 164. When the diagonal rack 165 of the second clip 15 is inserted through the passageway 1662, the first diagonal teeth 163 on one end of the first clip 14 are inserted between adjacent two second diagonal teeth 164 of the diagonal rack 165, which intermesh to secure the first clip 14 and the second clip 15 together. Also, the first helical teeth 163 are also provided to restrict the helical rack 165 of the second clip 15 from moving out in a direction opposite to the insertion direction (locking direction).

The second helical teeth 164 and the first helical teeth 163 are configured to cooperate to limit rotation of the first clamp 14 and the second clamp 15 in a direction opposite to the locking direction, thereby enabling the relative positions of one end of the first clamp 14 and one end of the second clamp 15 to be maintained.

It should be noted that while the present invention shows the securing structure of the various embodiments described above, the present invention also includes other suitable securing structures for maintaining the position of the clamp assembly.

Fig. 8 shows a perspective view of a mounting space of a first clip of a fastening assembly according to the present invention including a second embodiment. As previously mentioned, fig. 3A-3F illustrate that the first clip 14 includes the mounting space of the first embodiment. In the first and second embodiments of the installation space, two baffle members parallel to each other are provided on the outer surface of the yoke, and the space between the two baffle members defines the installation space, wherein the two baffle members may be an upper portion and a lower portion of the yoke, respectively. The installation space of the present invention also includes other embodiments, for example, an installation space of a third embodiment (see fig. 9A to 9C and fig. 12A to 12C) and an installation space of a fourth embodiment (see fig. 10A to 10C and fig. 13A to 13C) which are described in detail below. As will be described in detail below, the installation space of the third embodiment is defined by grooves provided on the outer surface of the yoke, and the installation space of the fourth embodiment is defined by spaces between two rows of protrusions provided on the outer surface of the yoke.

The installation space 801 of the second embodiment shown in fig. 8 is similar to the installation space 143 of the first embodiment shown in fig. 3A to 3F. The first clip 802 shown in fig. 8 is similar to the first clip 14 shown in fig. 3A-3F. In contrast, the radial width of the bottom plate 805 of the upper portion 803 and the bottom plate 806 of the lower portion 804 of the first clip 802 in fig. 8 is smaller compared to the first clip 14 in fig. 3A-3F, while instead a plurality of spaced apart protrusions 807, 808 are provided on the outer edges of the bottom plates 805, 806, respectively. Thus, the bottom plate 805 and the protrusions 807 of the upper portion 803 and the bottom plate 805 and the protrusions 808 of the lower portion 804 define therebetween the mounting space 801 of the second embodiment, which can accommodate the portion of the substrate 12 near the opening 121 as the mounting space 143 of fig. 3A to 3F. Also, when the first clip 802 is rotated toward its locking direction, the mounting space 801 of the first clip 802 always accommodates the base plate 12, thereby preventing the first clip 802 from moving in the axial direction of the opening 121 and causing the first clip 802 to fail to fix the cylindrical part 13 to the base plate 12. Also, the first clip 802 in fig. 8 does not have the rib in the first clip 14 shown in fig. 3A-3F. The second clip may be constructed identically to the first clip 802 of fig. 8.

It should be noted that, in order to maintain the position of the clip, the clip in fig. 8 may further include a fixing structure in fig. 1-2 and 6A-6B, and the mounting structure on one end of the clip in fig. 8 may be modified to have the fixing structure in fig. 7A-7C. In other embodiments, the clip of FIG. 8 may include other suitable structures.

Fig. 9A is a perspective view showing a mounting space of a fastening assembly including a third embodiment in a fastened state according to the present invention, fig. 9B is an exploded view of fig. 9A, and fig. 9C is a perspective view showing a first clip of the fastening assembly of fig. 9B.

As shown in fig. 9A-9C, the first clip 902 includes a base 903 and a plurality of wedge portions 904, the base 903 connecting the plurality of wedge portions 904 together. The base 903 is a generally arcuate plate with the inner surface of the wedge 904 connected to the outer surface of the base 903. A groove 905 is provided on the outer surface of the wedge 904, the groove 905 defining the mounting space 901 of the third embodiment. The mounting space 901 is for accommodating the substrate 12 along the opening 121 such that the first clip 902 does not move in the axial direction of the opening 121. The axially extending portion 909 of the groove 905 is identical in structure to the arcuate pressing surface 140 of the wedge member 144 in fig. 3A-3F, 4B and 5B for engaging the inner surface (first wedge surface 147) of the opening 121. When the first clamp 902 is rotated toward its locking direction, the mounting space 901 of the first clamp 902 always accommodates the base plate 12, thereby preventing the first clamp 902 from moving in the axial direction of the opening 121 so that the first clamp 902 cannot fix the cylindrical part 13 to the base plate 12. The first clip 902 can be integrally formed. The second clip 906 is identical in construction to the first clip 902 and is a mirror image of the first clip.

The fastening assembly shown in fig. 9A-9C may also include the securing structure shown in fig. 6A-6B for maintaining the position of the clip assembly. In particular, a first ratchet 17 is provided on an axially extending portion 909 of the recess 905 on the wedge 904 of the first clamp 902, which cooperates with a second ratchet 18, 19 on the first wedge surface 147 of the opening 121 to limit the rotation of the first clamp 902 in a direction opposite to its locking direction, so that, for example, the first clamp 902 can be held in its fastened position (see fig. 9A) without being released, so that the cylindrical part 13 remains fixed to the base plate 12. Correspondingly, a third ratchet is provided on the corresponding part of the recess 908 on the wedge-shaped portion 907 of the second clamp 906, which cooperates with a fourth ratchet on the second wedge-shaped surface 148 of the opening 121 to limit the rotation of the second clamp 906 in a direction opposite to its locking direction, so that the second clamp 906 can be held in its fastened position (see fig. 9A) without loosening, for example, so that the cylindrical part 13 remains fixed to the base plate 12. It should be noted that the fastening assembly shown in fig. 9A-9C may also include other suitable securing structures for maintaining the position of the clamp assembly.

Fig. 10A is a perspective view showing a fastening assembly including an installation space of a fourth embodiment in a fastened state according to the present invention, fig. 10B is an exploded view of fig. 10A, and fig. 10C is a perspective view showing a first clip of the fastening assembly of fig. 10B.

The installation space 1001 of the fourth embodiment shown in fig. 10A to 10C is similar to the installation space 901 of the third embodiment shown in fig. 9A to 9C. The first clip 1002 shown in fig. 10A-10C is similar to the first clip 902 shown in fig. 9A-9C. In contrast, the radial width of the plurality of wedge portions 1004 of the first clip 1002 in fig. 10A to 10C is made smaller compared to the first clip 902 in fig. 9A to 9C, and instead two rows of protrusions 1006 are provided on the outer surface of the plurality of wedge portions 1004 of the first clip 1002, the space between the two rows of protrusions 1006 defining the installation space 1001 of the fourth embodiment. As shown in fig. 10A to 10C, two rows of protrusions 1006 are disposed parallel to each other to define the above-described installation space 1001. The mounting space 1001 is for accommodating the substrate 12 along the opening 121 so that the first clip 1002 does not move in the axial direction of the opening 121. The wedge 1004 in fig. 10A-10C is similar to the wedge member 144 in fig. 3A-3F, 4B, and 5B, except that the height of the wedge 1004 is greater than the wedge member 144. The portion 1005 of the outer surface of the wedge 1004 between the two rows of protrusions 1006 and extending in the circumferential direction is of the same structure as the arcuate pressing surface 140 of the wedge member 144 for engaging the inner surface (the first wedge surface 147) of the opening 121. The first clip 1002 can be integrally formed or can be formed in other suitable manners. The second clip 1007 is identical in construction to the first clip 1002 and is a mirror image of the first clip.

The fastening assembly shown in fig. 10A-10C may also include the securing structure shown in fig. 6A-6B for maintaining the position of the clip assembly. Specifically, a first ratchet 17 is provided on a portion 1005 of the outer surface of the wedge 1004 of the first clamp 1002 that cooperates with a second ratchet 18, 19 on the first wedge surface 147 of the opening 121 to limit rotation of the first clamp 1002 in a direction opposite to its locking direction, such that, for example, the first clamp 1002 may be held in its tightened position (see fig. 10A) without loosening, such that the cylindrical part 13 remains secured to the base plate 12. Correspondingly, a third ratchet tooth is provided on a corresponding portion 1009 of the outer surface of the wedge 1008 of the second clamp 1007, which cooperates with a fourth ratchet tooth on the second wedge surface 148 of the opening 121 to limit rotation of the second clamp 15 in a direction opposite to its locking direction, such that, for example, the second clamp 15 can be held in its fastened position (see fig. 10A) without being released, so that the cylindrical part 13 remains fixed to the base plate 12. It should be noted that the fastening assembly shown in fig. 10A-10C may also include other suitable securing structures for maintaining the position of the clamp assembly.

And, while the present invention shows the mounting spaces of the various embodiments described above, the present invention also includes other suitable mounting spaces for preventing axial movement of the clamp assembly along the opening during adjustment of the position.

Fig. 11A shows a cross-sectional view of a fastening assembly in an initial state including a wedge member of a second embodiment according to the present invention, fig. 11B shows a cross-sectional view of a fastening assembly in a fastened state including a wedge member of a second embodiment according to the present invention, fig. 11C shows a cross-sectional view of a fastening assembly in fig. 11B including a fixing structure of a second embodiment, and fig. 11D shows a cross-sectional view of a fastening assembly in fig. 11B including a fixing structure of a third embodiment.

As shown in fig. 11A-11B, the first clip 1101 of the fastening assembly may be similar to the first clip shown in fig. 3A-3F and 8. In contrast, the first clamp 1101 of FIGS. 11A-11B includes a wedge-shaped member 1102 for engaging the opening 121 of the base plate 12, the opening 121 being generally circular. The second clip 1103 is disposed as a mirror image of the first clip 1101, and the second clip 1103 includes a wedge member 1104. In an initial state (see fig. 11A) in which the fastening assembly is in, when the first clip 1101 is rotated in a preset locking direction (i.e., counterclockwise) and the second clip 1103 is rotated in the preset locking direction (i.e., clockwise), the inner surface of the opening 121 can apply a radial force to the outer surfaces of the wedge-shaped members 1102 of the first clip 1101 and the wedge-shaped members 1104 of the second clip 1103, so that the receiving space of the inner sides of the first clip 1101 and the second clip 1103 becomes gradually smaller. Finally, the accommodation space of the inner sides of the first and second clips 1101 and 1103 is minimized so that the fastening assembly reaches the fastened state as shown in fig. 11B, and the first and second clips 1101 and 1103 reach the fastened position. At this time, the inner surfaces of the opening 121 firmly hold the first and second clips 1101 and 1103 against the cylindrical part 13, so that the first and second clips 1101 and 1103 firmly fix the cylindrical part 13 to the base plate 12. In a fastened state (see fig. 11B) in which the fastening assembly is in, when the first clip 1101 is rotated in a direction opposite to a preset locking direction (i.e., clockwise) or the second clip 1103 is rotated in a direction opposite to the preset locking direction (i.e., counterclockwise), the receiving space of the inner sides of the first clip 1101 and the second clip 1103 becomes gradually larger, thereby enabling the clip assembly to separate the cylindrical part 13 from the base plate 12.

The first clip 1101 and the second clip 1103 shown in fig. 11C include the securing structure shown in fig. 6A for maintaining the position of the clip assembly. Specifically, the wedge-shaped member 1102 of the first clamp 1101 is provided with a first ratchet 17 on its outer surface that cooperates with a second ratchet 18 provided on the inner surface of the opening 121 to limit rotation of the first clamp 1101 in a direction opposite to its locking direction (i.e., clockwise) so that, for example, the first clamp 1101 can be held in its fastened position without being released, thereby allowing the cylindrical part 13 to remain secured to the base plate 12. Correspondingly, a third ratchet 20 is provided on the outer surface of the wedge-shaped member 1104 of the second clip 1103, which cooperates with a fourth ratchet 21 provided on the inner surface of the opening 121 to limit rotation of the second clip 1103 in a direction opposite to its locking direction (i.e. counter-clockwise) so that, for example, the second clip 1103 can be held in its fastened position without being released, so that the cylindrical part 13 remains fixed to the base plate 12.

The first clip 1101 and the second clip 1103 shown in fig. 11D include the securing structure shown in fig. 6B for maintaining the position of the clip assembly. Specifically, the first clamp 1101 is provided with a first ratchet 17 on the outer surface of the wedge-shaped member 1102 that cooperates with the teeth 191 of the second ratchet 19 provided on the inner surface of the opening 121 to limit rotation of the first clamp 1101 in a direction opposite to its locking direction (i.e., clockwise) so that, for example, the first clamp 1101 can be held in its fastened position without being released, thereby allowing the cylindrical part 13 to remain secured to the base plate 12. In addition, as in fig. 6B, a slit 192 is provided in the base plate 12 from the front end of the teeth 191 toward the rear end of the teeth 191. Correspondingly, a third ratchet 22 is provided on the outer surface of the wedge-shaped member 1104 of the second clip 1103, which cooperates with the teeth 231 of the fourth ratchet 23 provided on the inner surface of the opening 121 to limit the rotation of the second clip 1103 in a direction opposite to its locking direction, so that, for example, the second clip 1103 can be held in its fastened position without being released, so that the cylindrical part 13 remains fixed to the base plate 12. In addition, as in fig. 6B, a slit 232 is provided in the substrate 12 from the front end of the tooth 231 toward the rear end of the tooth 231.

It should be noted that the first clip and the second clip in fig. 11A to 11B may include the upper and lower portions shown in fig. 3A to 3F and 8 to have corresponding installation spaces, and may further include the fixing structures of the various embodiments shown in the present invention. The first and second clips of fig. 11A-11B may include other suitable structures.

Fig. 12A is a perspective view showing a mounting space of the fastening assembly of fig. 11B including a third embodiment, fig. 12B is an exploded view of fig. 12A, and fig. 12C is a perspective view showing a first clip of the fastening assembly of fig. 12B.

The fastening assembly shown in fig. 12A-12C is similar to the fastening assembly shown in fig. 9A-9C. In contrast, the first clip 1202 of the fastening assembly of fig. 12A-12C includes a wedge 1203 with a recess 1204 formed in an outer surface of the wedge 1203, the recess 1204 defining a mounting space 1201. The mounting space 1201 is for receiving the substrate 12 along the substantially circular opening 121 such that the first clamp 1202 does not move in the axial direction of the opening 121. An axially extending portion 1206 of the recess 1204 is for engaging an inner surface of the opening 121. The second clamp 1205 of the fastening assembly of fig. 12A-12C is identical in construction to the first clamp 1202 and is a mirror image of the first clamp.

Fig. 13A shows a perspective view of a mounting space of the fastening assembly of fig. 11B including the fourth embodiment, fig. 13B shows an exploded view of fig. 12A, and fig. 13C shows a perspective view of a first clip of the fastening assembly of fig. 13B.

The fastening assembly shown in fig. 13A-13C is similar to the fastening assembly shown in fig. 10A-10C. In contrast, the first clip 1302 of the fastening assembly of fig. 13A-13C includes a wedge-shaped member 1303 having two rows of protrusions 1304 disposed on an outer surface of the wedge-shaped member 1303, the space between the two rows of protrusions 1304 defining a mounting space 1301. The mounting space 1301 is for receiving the substrate 12 along the substantially circular opening 121 such that the first clamp 1302 does not move in the axial direction of the opening 121. A portion 1306 of the outer surface of wedge-shaped member 1303 between the two rows of protrusions 1304 and extending in the circumferential direction is adapted to engage the inner surface of opening 121. The second clip 1305 of the fastening assembly of fig. 13A-13C is identical in construction to the first clip 1302 and is a mirror image of the first clip.

The embodiments shown in fig. 11A-11D, 12A-12C and 13A-13C have the advantage over the embodiments shown in the previous figures that the structure of the clip is simpler and that the opening in the base plate can be designed as a circular hole without the need to redesign the shaped structure of the several embodiments described above. The machining cost of an opening designed as a round hole is lower, since the round hole means that it can be machined using a common drilling tool, resulting in a lower machining cost for the opening; the special-shaped hole means that a specially-shaped cutter or die is needed for machining, so that the machining cost is higher. The clip of the embodiment shown in fig. 11A-11D, 12A-12C and 13A-13C is simpler in construction, e.g. the clip is designed with a wedge-shaped member or a securing structure is provided on the outer surface of the wedge-shaped member (see fig. 6A-6B), and correspondingly a securing structure is provided on the opening to cooperate with the securing structure on the wedge-shaped member. The reduced number of wedge members and securing structures of the clip and corresponding securing structures on the opening results in a lower tooling cost and less time consuming processing of the clip.
