DETAILED DESCRIPTION
[0030] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] refer to Figures 1 to 12 :
[0032] The utility model discloses a double-hook air outlet bracket, including a fixing seat 10, an adjustment component 20, a bracket connector 30 and a hook 40. One side of the adjustment component 20 is provided with a bracket connector 30, and the other side is provided with a fixing seat 10, wherein the bracket connector 30 is preferably a ball head connector for subsequent connection with a substantial bracket such as a mobile phone bracket, a tablet holder, etc., and one side of the fixing seat 10 extends Hook 40 The adjustment component 20 can adjust the extension and extension of the hook 40 relative to the fixing seat 10. Extension means retraction, and extension means outward extension. When the hook 40 is extended, it can be used to position the grille blades of the automobile air-conditioning outlet (hereinafter referred to as grille blades). When retracted, the hook 40 can just hook the grille blades, thereby fixing the bracket. Specifically, as a difference from the traditional air outlet bracket, in this case, the hook 40 includes a first hook 1 and a second hook 2 arranged in sequence in the longitudinal direction, and a spacing adjustment component 50 is connected to the hook at at least one end, that is, the inner side of the first hook 1 is connected to the spacing adjustment component 50, or the inner side of the second hook 2 is connected to the spacing adjustment component 50, or the inner sides of the first hook 1 and the second hook 2 are both connected to the spacing adjustment component 50. As a control link, the control end of the spacing adjustment component 50 passes out of the fixing seat 10.
[0033] Example 1: In this embodiment, the adjustment assembly 20 includes a knob 3, a movable part 4 and a guide rod. A limit guide rod 301 extends from one side of the bracket connector 30. The limit guide rod 301 extends into the inner side of the knob 3. The inner side of the knob 3 is hollowed out and has an internal thread 31 on the inner wall. The movable part 4 is arranged on the inner side of the knob 3 and the outer side of the movable part 4 is provided with an external thread 41 that is screwed together with the internal thread 31. The movable part 4 is provided with a limit guide groove 42 that slides with the limit guide rod 301. As a result, the movable part 4 is limited by the sliding limit of the limit guide rod 301. It can only slide in the cavity inside the knob 3, and the driving source for sliding comes from the internal thread 31 of the knob 3 and the external thread 41 of the movable part 4. When the knob 3 is rotated, the knob 3 and the movable part 4 are threadedly matched to drive the movable part 4 to move along the axial direction of the knob 3. One end of the first hook 1 and the second hook 2 are fixedly connected to the movable part 4, and the other end extends outward through the slot on the fixed seat 10. Therefore, rotating the knob 3 can move the first hook 1 and the second hook 2. Specifically, the first hook 1 and the second hook 2 both include a fixing part 401, a hook part 402 and a supporting part 403.
[0034] Specifically, the spacing adjustment component 50 includes a pressing member 51, a return spring 52, a first guide pin 53 (movable member) and a second guide pin 54. One side of the pressing member 51 abuts against the first hook 1. The abutment here is preferably a non-fixed abutment, that is, the pressing member 51 abuts against the first hook 1 when pressed downward, driving the first hook 1 to move downward, but is rebounded upward by the return spring 52. When the pressing member 51 lacks pressing force, the first hook 1 abuts upward against the pressing member 51. At the same time, when the knob 3 is turned to cause the movable member 4 to move, it will move the first hook 1 and the second hook 2 inward or outward. Therefore, the pressing member 51 here does not affect the horizontal extension and retraction action of the first hook 1, which is thus interpreted as a non-fixed abutment. A first guide groove 55 is provided on one side of the fixed seat 10, and the pressing member 51 is slidably arranged on the first guide groove. The movable part 4 is provided with a first guide pin 53 (movable part), and one side of the fixed part 401 of the first hook part 1 is just passed through by the first guide pin 53 (movable part) and is longitudinally guided by the first guide pin 53 (movable part). The inner side of the fixed seat 10 is provided with a second guide pin 54, and the second guide pin 54 is used for the reset spring 52 to be sleeved and reset.
[0035] Specifically, the support portion 403 of the first hook member 1 close to the hook side is provided with a first avoidance groove 58, and the support portion 403 of the second hook member 2 is provided with a second avoidance groove 59. The first avoidance groove 58 and the second avoidance groove 59 correspond in longitudinal position. The second guide pin 54 passes through the first avoidance groove 58 and the second avoidance groove 59 respectively. The first avoidance groove 58 and the second avoidance groove 59 are both horizontally opened along their respective support portions 403, so as to facilitate the first hook member 1 and the second hook member 2 to avoid the second guide pin 54 when moving. The return spring 52 is sleeved on the second guide pin 54 and is arranged between the first hook member 1 and the second hook member 2. In this embodiment, the second hook member 2 is arranged at the bottom, and the first hook member 1 is arranged at the upper end of the second hook member 2. The second hook 2 cannot be displaced longitudinally The first hook 1 can slide up and down in the longitudinal direction by relying on the pressing piece 51 and the return spring 52, as well as the guiding effect of the first guide pin 53 (movable piece). When it needs to be inserted into the blade grille, it is inserted through the holes between several adjacent or spaced blade grilles, and then the pressing piece 51 is pressed to make the first hook 1 move closer to the second hook 2. When it just abuts against a certain blade grille, the knob 3 is turned to retract the first hook 1 and the second hook 2, and the two hooks are completely hooked on the inside of the two blade grilles. Because of the longitudinal displacement adjustment of the first hook, the two hooks can be adjusted to the middle of their respective blade grilles and then retracted, so their hooked positions are all in the center, which is more stable and not easy to slip or loosen.
[0036] Specifically, in order to limit the up and down stroke of the pressing member 51, an inner slide groove 511 is provided on the inner side of the pressing member 51, and a limiting protrusion 551 is provided on the inner side of the first guide groove 55. The inner slide groove 511 cooperates with the limiting protrusion 551 to limit the up and down stroke.
[0037] Example 2: Specifically, the single-side hook in the aforementioned disclosed Example 1 can be adjusted longitudinally, and the adjustment range achieved is limited. It is difficult to adapt to some large-diameter and large-span air-conditioning vents. Or when fixing heavy electronic products, the user may choose to fix two hooks 40 across multiple blade grilles at the same time. The technical solution of Example 1 is difficult to meet the requirements. Therefore, Example 2 is provided. In this embodiment, the adjustment component 20 includes a knob 3, a movable part 4, a driving part 6, a limit guide rod 301 and a guide sleeve 9, and the bracket connector 3 0 and the fixed seat 10 are sequentially provided with a knob 3 and a guide sleeve 9, the inner sides of the knob 3 and the guide sleeve 9 are both hollowed out, the driving member 6 and the movable member 4 are arranged on the inner sides of the knob 3 and the guide sleeve 9, and the movable member 4 and the guide sleeve 9 are guided and limited. Preferably, the inner side of the guide sleeve 9 has a guide groove or a guide track, and the outer side of the movable member 4 has a sliding guide component that cooperates with the guide groove or the guide track, or the outer contour of the simple movable member 4 is just equivalent to the inner contour of the guide sleeve 9, so that the limited guide cooperation can also be achieved. One side of the bracket connector 30 is provided with The limiting guide rod 301 is provided with an inner tooth pattern 32 on the annular surface of the inner wall of the knob 3. The driving member 6 includes a driving head 61 and a driving rod 62. The outer side of the driving head 61 is provided with an outer tooth pattern 611 that meshes with the inner tooth pattern 32. The driving rod 62 is provided with an external thread 41. The movable member 4 is provided with an inner screw hole 621 and a limiting guide groove 42 in sequence, wherein the inner screw hole 621 is screwed with the driving rod 62, and the limiting guide groove 42 is matched with the limiting guide rod 301. One end of each of the first hook 1 and the second hook 2 is connected to the inner screw hole 621. The movable part 4 is fixedly connected, and the other end extends outward through the slot on the fixing seat 10. The first hook 1 and the second hook 2 both include a fixing portion 401, a hook portion 402 and a supporting portion 403, wherein the fixing portion 401 is used to be fixedly connected to the movable part 4, and the hook portion 402 is used to hook tightly with the blade grille. The difference here from Example 1 is that this embodiment provides an embodiment in which both the first hook 1 and the second fastener can be longitudinally adjusted. In this way, a larger stroke of adjustment can be achieved, and it can be adapted to the use of air-conditioning outlets with more blade grille specifications.
[0038] As mentioned above, there are two normal limiting guide rods 301, one of which cooperates with the limiting guide groove 42. Here, the other limiting guide rod 301 can be passed through the driving rod 62 to provide a limit for the driving rod 62 or act as a rotating shaft, so that the driving rod 62 can be stabilized at one side.
[0039] Specifically, the spacing control component 50 includes a first pressing member 7, a second pressing member 8, a first guide pin 53 (movable member), a second guide pin 54 and a return spring 52. The inner sides of the first pressing member 7 and the second pressing member 8 are respectively in a passable abutment with the first hook 1 and the second hook 2. There are two implementation schemes here. Taking the first hook 1 and the first pressing member 7 as an example, one is that the support portion 403 of the first hook 1 passes through one side of the first pressing member 7 and can move inside the first pressing member 7. The second is that the first hook 1 does not pass through one side of the first pressing member 7, but is just located on the inner side of the first pressing member 7. In this way, the first pressing member 7 can abut the upper end surface of the first hook 1 when pressed inward, and the first hook 1 moves with the movable member 4. It will not be affected by the first pressure piece 7. A first guide pin 53 (movable piece) is provided on the inner side of the movable piece 4, and a second guide pin 54 is provided on the inner side of the fixed seat 10. One side of the fixed portion 401 of the first hook piece 1 and the second hook piece 2 is just passed through the upper and lower ends of the first guide pin 53 (movable piece) and guided by the first guide pin 53 (movable piece). The support portion 403 of the first hook piece 1 is provided with a first avoidance groove 58, and the support portion 403 of the second hook piece 2 is provided with a second avoidance groove 59. The second guide pin 54 passes through the first avoidance groove 58 and the second avoidance groove 59 respectively. The reset spring 52 is sleeved on the second guide pin 54 and is arranged between the first hook piece 1 and the second hook piece 2 or the first pressure piece 7 and the second pressure piece 8.
[0040] Specifically, the fixing parts 401 of the first hook 1 and the second hook 2 are each provided with a guide opening 57, the upper and lower ends of the inner side of the fixing seat 10 are each provided with a first guide groove 55, the upper and lower ends of the inner side of the movable part 4 are each provided with a second guide groove 56 (movable part), the guide opening 57 just cooperates with the second guide groove 56 (movable part) for positioning, the first pressing part 7 and the second pressing part 8 just cooperate with the longitudinal limit guide in the first guide groove 55, the inner side of the first pressing part 7 and the second pressing part 8 are both provided with an inner slide groove 511, the inner side of the first guide groove 55 is provided with a limit protrusion 551, the inner slide groove 511 cooperates with the limit protrusion 551 for up and down travel limiting.
[0041] Specifically, in order to make the first pressure piece 7 and the second pressure piece 8 more stable during the up and down pressing process, an inner guide groove 552 is provided on the side wall of the first guide groove 55, and the side of the first pressure piece 7 and the second pressure piece 8 is provided with an outer guide block 703 that slides with the inner guide groove 552. The inner horizontal ends of the first pressure piece 7 and the second pressure piece 8 are both provided with a cross groove 801, and the support parts 403 of the first hook 1 and the second pressure piece 8 can be arranged in a pass-through manner in the cross groove 801. The setting of the cross groove 801 can provide an additional stable support point for the first hook 1 and the second hook 2 when they move again, making the first hook 1 and the second hook 2 more stable when they move horizontally. The inner longitudinal ends of the first pressure piece 7 and the second pressure piece 8 are both provided with a longitudinal through hole 802, and the first guide pin 53 (movable part) passes through the longitudinal through hole 802. With this setting, the first pressure piece 7 and the second pressure piece 8 also have an additional limiting guide component during the process of longitudinal clamping and being reset by the reset spring 52.
