Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.

The present embodiment relates to a bracket base with adjustable clamping force, as shown in fig. 1 and 2, comprising: the connecting head 1, first arm lock 2, connecting seat 3, second arm lock 4 and clamp force adjusting part 5.

Wherein, the connector 1 is a universal head. The connecting seat 3 is fixedly connected between the connecting head 1 and the first clamping arm 2, and an accommodating cavity a is arranged on the connecting seat 3. The second clamping arm 4 is movably assembled in the accommodating cavity a through the connecting end 41 and is matched with the first clamping arm 2 for use. The clamp force adjusting part 5 passes through the connecting seat 3 and is connected with the connecting end 41, and the clamp force adjusting part 5 is used for controlling the first clamping arm 2 and the second clamping arm 4 to clamp and open and adjust the clamp force to be applicable to the air outlet of different types and not cause the injury and the phenomenon that the centre gripping is not firm to the air outlet.

Further, in order to facilitate the installation of the second clamping arm 4, the connecting seat 3 comprises: a first housing 31 and a second housing 32. The two ends of the first housing 31 are respectively fixedly connected with the connecting end 41 and the first clamping arm 2. The second housing 32 is detachably mounted on the first housing 31. Specifically, the first housing 31 and the second housing 32 are semi-cylindrical, and the first housing 31 and the second housing 32 are clamped.

It should be noted that the first clamping arm 2, the connector 1 and the first housing 31 are integrally formed. The second clamping arm 4 and the connecting end 41 are of an integrally formed structure.

Further, the clamping force adjusting assembly 5 includes: a pull rod 51, a locking member, a spring 53 and a nut 54. One end of the pull rod 51 movably penetrates through the connecting seat 3 and is connected with the connecting end 41, and the pull rod 51 is used for driving the connecting end 41 to move so as to enable the second clamping arm 4 to approach the first clamping arm 3 for clamping. The locking piece is assembled at the other end of the pull rod 51 and is matched with the outer wall of the connecting seat 3 to lock the pull rod. The spring 53 is sleeved on the pull rod 51 and located between the connecting end 41 and the inner wall of the connecting seat 3, and is used for resetting the connecting end 41 and the second clamping arm 4.

The pull rod 51 movably penetrates through the connecting end 41 to be in threaded connection with the nut 54, and a nut guide anti-rotation groove is formed in the connecting seat 3 corresponding to the nut 54. The locking piece can be rotated to drive the pull rod 51 to rotate, so that the distance between the wrench 52 and the nut 54 can be adjusted to finely adjust the clamping force, and a better clamping effect is realized. Preferably, the nut is a hand-threaded nut.

Further, the first clamping arm 2 and the second clamping arm 4 abut against each other near one end of the connector 1. In this embodiment, the locking member is a wrench 52, the wrench 52 is rotatably mounted at the other end of the pull rod 51 through a rotating shaft 55, and the side surface of the wrench and the outer wall of the connecting base 3 are pressed against each other by a spring 53. The vertical distance between the side surfaces of the wrench 52 parallel to the rotating shaft 55 and the rotating shaft 55 decreases from the front side to the rear side, so that the clamping force can be quickly adjusted by switching the side surfaces abutting against the connecting socket 3. In other embodiments, the retaining member is a hand nut and the retaining member is a hand nut that is threadably coupled to the pull rod 51.

Preferably, the wrench 52 has four shift positions for adjusting the clamping force, and the four shift positions are sequentially arranged from front to back. When pulling the wrench 52 backward, the wrench 52 rotates around the rotating shaft 55 and switches the side face abutting against the connecting seat 3, the pull rod 51 drives the connecting end 41 to move towards the side close to the wrench 52, and the second clamping arm 4 of the corresponding second clamping arm 4 swings towards the side close to the first clamping arm 2 by taking the side abutting against the first clamping arm 2 as a fulcrum, so as to increase the clamping force of the first gear. The reverse pulling reduces the clamping force of the first gear.

Preferably, to save the space occupied by the compressed spring 53, the ends of the spring 53 are directly tapered toward the middle.

Further, in order to improve the clamping reliability of the bracket base, a lantern ring 6 is sleeved between the connecting seat 3 and each clamping arm. The first clamping arm 2 and the second clamping arm 4 are provided with a first arc-shaped limiting part 22 and a second arc-shaped limiting part 43 which are used for preventing the lantern ring 6 from sliding out, and one end of the lantern ring 6 is close to one end of the lantern ring 6. One side of the lantern ring 6 is connected with a support arm 7 for supporting around the air outlet, and one side of the support arm 7 far away from the connecting end 41 is provided with a first anti-skid pad 71. The collar 6, the arm 7 and the first anti-skid pad 71 together form a support.

When this support base is out of work, the support can carry out 360 degrees rotations in order to carry out the regulation of angle to be applicable to different kinds of automobile air outlets. When the pull rod 51 drives the connecting end 41 to move towards the side close to the wrench 52, the second clamping arm 7 swings towards the side close to the first clamping arm 7 to clamp on the automobile air outlet, meanwhile, the connecting end 41 generates great pressure on the inner wall of the sleeve ring 6, and the support is locked, so that the support is effectively prevented from loosening in the using process and the installation stability of the support base is prevented from being influenced.

During installation, place the nut in nut 54 direction rotation-proof slot c earlier, then overlap the lantern ring 6 on first arm lock 2, be located between first arc spacing portion 22 connecting seat 3, pass lantern ring 6 with the link of second arm lock 7 again and insert and hold in cavity an, finally, install spring 53 and glue and fix second casing 32 admittedly. Preferably, the connecting end 41 is provided with a limiting lug 411, a limiting block 321 is arranged in the second housing 32 corresponding to the limiting lug 411, and the connecting end 41 is matched with the limiting block 321 through the limiting lug 411 to prevent slipping out. The thickness of stopper 321 is greater than the interval of the notch of stopper 321 direction anti-rotation groove and link 41 to prevent falling out after dismantling pull rod 51, the user is difficult to reinstall, and leads to this support base to be useless.

Furthermore, a second anti-slip pad 21 and a third anti-slip pad 42 are respectively arranged on the clamping surfaces of the first clamping arm 2 and the second clamping arm 4 to prevent scratching of the air outlet of the automobile.

The working principle of the utility model is as follows: during the use, only need insert first arm lock 2 and second arm lock 4 on the air outlet, then pull spanner 52 backward until first arm lock 2 and second arm lock 4 press from both sides tightly in air outlet department, can further twist spanner 5 and finely tune second arm lock 4 according to the demand to realize better centre gripping effect. Therefore, the clamping force can be adjusted according to the size of the automobile air outlet, so that the support base is stably fixed at the air outlet.

The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
