Description

Technical Field

[0001] The utility model relates to the technical field of sucker brackets, in particular to a sucker bracket base. Background Art

[0002] At present, sucker brackets are mainly used as fixed accessories for mobile phones, camera devices or other intelligent devices and are widely used in daily life. Existing sucker brackets are mainly fixed by sucking on an object with a sucker having an adhesive.

[0003] For example, in the technical solution disclosed in a sucker bracket of a Chinese utility model patent with the application number 202320683949.0, which uses a sucker to adsorb and has a protruding piece for taking on the side end of the sucker. Although this technical solution can utilize the sucker to adsorb and realize the disassembly and assembly of the sucker bracket by pulling the protruding piece to remove the sucker, since the protruding piece is arranged on the edge of the sucker, there is a problem that the adsorption of the sucker may fail due to accidental contact with the protruding piece during use.

[0004] Therefore, it is urgent to research and develop a sucker bracket base to solve the problem that the sucker bracket is prone to failure due to accidental contact. Summary of the Invention

[0005] The purpose of the utility model is to provide a sucker bracket base, which can improve the adsorption stability of the sucker bracket base.

[0006] In order to achieve the above purpose, a sucker bracket base provided by the utility model has the following specific implementation schemes:

[0007] A sucker bracket base includes:

[0008] A seat body;

[0009] A sucker, arranged at the bottom of the seat body;

[0010] A connecting rod, arranged on the seat body and connected to the sucker, and a pin shaft is also connected to the connecting rod; and

[0011] A climbing track, arranged on the seat body, and the pin shaft is in limit fit with the climbing track;

[0012] Wherein, the relative climbing movement of the pin shaft along the climbing track drives the connecting rod and the sucker to lift to form a vacuum negative pressure cavity, or the relative descending movement of the pin shaft along the climbing track drives the connecting rod and the sucker to reset to release the vacuum negative pressure in the vacuum negative pressure cavity.

[0013] A sucker bracket base of the present utility model, compared with the prior art, by arranging a connecting rod on the seat body, connecting the connecting rod with a sucker arranged at the bottom of the seat body, and connecting a pin shaft on the connecting rod which is in limit fit with a climbing track on the seat body. During use, the relative climbing movement of the pin shaft along the climbing track is used to drive the lifting of the connecting rod and the sucker on the connecting rod, so that the sucker generates an upward deformation, thereby forming a vacuum negative pressure cavity between the sucker and the object it contacts, realizing the adsorption of the sucker and the contacted object. Conversely, the relative descending movement of the pin shaft along the climbing track is used to drive the connecting rod and the sucker on the connecting rod to reset, releasing the vacuum negative pressure cavity, and realizing the separation of the sucker and the adsorbed object. Compared with the structure of arranging protruding pieces on the edge of the sucker, the present utility model requires driving the pin shaft to move on the climbing track to realize the adsorption or separation of the sucker, which can effectively prevent the adsorption failure caused by accidental touch and improve the adsorption stability of the sucker bracket seat body.

[0014] In some of the embodiments, a rotating member capable of rotating relative to the seat body is provided on the seat body, the climbing track is formed on the rotating member, the pin shaft is mounted on the rotating member, and the end extends into the climbing track;

[0015] Wherein the climbing track includes a first limit point and a second limit point, the first limit point is higher than the second limit point, and the pin shaft is in limit fit with both the first limit point and the second limit point.

[0016] By arranging a rotating member on the base that can rotate relative to the seat body, forming the climbing track on the rotating member, mounting the pin shaft of the connecting rod on the rotating member, and the end extending into the climbing track, it is ensured that the pin shaft can perform a relative climbing movement along the climbing track. And different height first limit point and second limit point are set on the climbing track. In the initial state, the pin shaft is located within the lower second limit point. When the sucker needs to adsorb the object it contacts, the rotating member rotates relative to the base, causing the pin shaft to displace to the higher first limit point while driving the connecting rod and the sucker to lift, so that the sucker deforms to form a vacuum negative pressure cavity to realize the adsorption with the object; conversely, the rotating member rotates reversely and resets on the base, the pin shaft moves downward along the climbing track and returns to the second limit point again, and the connecting rod and the sucker reset to release the vacuum negative pressure cavity, so that the sucker is separated from the adsorbed object, improving the convenience of adsorption and separation between the sucker bracket base and the object.

[0017] In some of the embodiments, the sucker and the seat body are movably matched to form a first state or a second state, and the rotating member rotates relative to the seat body to form a first position and a second position;

[0018] In the first state, the rotating member rotates relative to the base from a first position to a second position, and the pin shaft relatively climbs from a second limit point in the climbing track to a first limit point, driving the connecting rod and the suction cup to lift. The suction cup deforms to form a vacuum negative pressure cavity, forming an adsorption state.

[0019] In the second state, the rotating member rotates relative to the seat body from the second position back to the first position, and the pin shaft relatively descends from the first limit point of the climbing track back to the second limit point, driving the connecting rod and the suction cup to reset, releasing the vacuum negative pressure in the vacuum negative pressure cavity, forming a detachment state.

[0020] By adopting a rotating member that can rotate relative to the seat body, the pin shaft relatively climbs or relatively descends along the climbing track. The switching of the pin shaft between the first limit point and the second limit point realizes the switching of the adsorption state or the detachment state of the suction cup, improving the disassembly and assembly convenience of the base of the suction cup bracket.

[0021] In some embodiments, there are two climbing tracks, which are oppositely arranged at the top position of the rotating member.

[0022] By arranging the climbing tracks in a structure of two oppositely arranged at the top of the rotating member, the stability of the pin shaft switching the limit point in the climbing track when the rotating member rotates is improved.

[0023] In some embodiments, a first cover is provided on the seat body, the rotating member, the connecting rod and the pin shaft are located inside the first cover, and a swinging groove is opened on the first cover.

[0024] A swinging rod is connected to the rotating member, and the end of the swinging rod passes through the swinging groove and extends outside the first cover.

[0025] By adopting a structure in which a swinging rod is arranged on the rotating member and the end of the swinging rod passes through the swinging groove of the first cover and extends outside the first cover, the user can realize the disassembly and assembly of the suction cup by simply rotating the swinging rod within the range formed by the swinging groove. On the one hand, the disassembly and assembly convenience can be improved. On the other hand, the swinging rod needs to break through the limit of the first limit point or the second limit point on the pin shaft and the climbing track to rotate. Even if there is an accidental touch during use, it will not cause the adsorption failure of the suction cup, improving the use stability.

[0026] In some embodiments, an installation groove is provided on the top surface of the seat body, and the rotating member is arranged in the installation groove.

[0027] At least one rubber ring is provided between the bottom of the rotating member and the installation groove, and the rubber ring abuts against the rotating member and the installation groove respectively.

[0028] By providing an installation groove on the base body and installing a rotating member on the installation groove, the connection stability between the rotating member and the base is improved. Moreover, a rubber ring is provided between the bottom of the rotating member and the installation groove, and the rotational friction of the rotating member is increased by using the rubber ring, further preventing the rotating member from rotating due to accidental touch and improving the adsorption stability.

[0029] In some embodiments, a first limiting rod is provided on the top surface of the base body, and a first arc-shaped limiting groove is formed in the rotating member. The first limiting rod passes through the first arc-shaped limiting groove and is in limiting cooperation with both ends of the first arc-shaped limiting groove.

[0030] By providing a first limiting rod on the base body and forming a first arc-shaped limiting groove in the rotating member, and using the limiting cooperation between the first limiting rod and both ends of the first arc-shaped limiting groove, and in combination with the climbing track of the rotating member, the rotation angle of the rotating member is limited, avoiding the situation of damage to the suction cup caused by excessive rotation angle.

[0031] In some embodiments, a return spring is sleeved on the connecting rod. One end of the return spring abuts against the suction cup, and the other end abuts against the rotating member.

[0032] By sleeving a return spring on the connecting rod, when the rotating member rotates to drive the pin shaft to climb, the suction cup is lifted to compress the return spring, so that during the process of canceling the vacuum negative pressure chamber, the return spring can provide assistance, improving the convenience of the separation between the suction cup support base and the object.

[0033] In some embodiments, a second cover body is provided on the base body. The second cover body rotates relative to the base body. The rotating member, the connecting rod and the pin shaft are located inside the second cover body, and a connecting sleeve is provided inside the second cover body;

[0034] A connecting convex block is provided on the outer wall of the rotating member, and a connecting groove is provided on the inner wall of the connecting sleeve. The connecting convex block is in plug-in fit with the connecting groove.

[0035] By sleeving the connecting sleeve on the second cover body that rotates relative to the base body on the rotating member, and the rotating member and the connecting sleeve are fixedly connected through the plug-in fit of the connecting convex block and the connecting groove, so that the second cover body can drive the rotating member to rotate during the rotation process, improving the convenience of adsorption and separation of the suction cup support base.

[0036] In some embodiments, at least one second limiting rod is provided on the top surface of the base body, and a second arc-shaped limiting groove corresponding to the second limiting rod is provided on the second cover body. The second limiting rod passes through the second arc-shaped limiting groove and is in limiting cooperation with both ends of the second arc-shaped limiting groove.

[0037] By providing at least one second limiting rod on the seat body and a second arc-shaped limiting groove corresponding to the second limiting rod on the second cover body, the limiting cooperation at both ends of the second limiting rod and the second arc-shaped limiting groove, as well as the limiting cooperation between the pin shaft and the two limiting points of the climbing track, are used to limit the rotation angle of the second cover body, avoiding the situation that the lifting height of the connecting rod is too high due to excessive rotation angle, resulting in damage to the suction cup.

[0038] Based on the above technical solutions, the present utility model has the following beneficial effects compared with the prior art:

[0039] By providing a connecting rod on the seat body, using the connecting rod to connect with the suction cup arranged at the bottom of the seat body, and connecting a pin shaft on the connecting rod that is in limiting cooperation with the climbing track on the seat body, during use, the relative climbing movement of the pin shaft along the climbing track is used to drive the connecting rod and the suction cup on the connecting rod to lift, causing the suction cup to deform upward, so that a vacuum negative pressure cavity is formed between the suction cup and the object it contacts, realizing the adsorption of the suction cup to the contacted object. Conversely, the relative downward movement of the pin shaft along the climbing track is used to drive the connecting rod and the suction cup on the connecting rod to reset, releasing the vacuum negative pressure cavity, and realizing the separation of the suction cup from the adsorbed object. Compared with the structure of providing protruding pieces on the edge of the suction cup, the present utility model requires driving the pin shaft to move on the climbing track to achieve the adsorption or separation of the suction cup, which can effectively prevent the adsorption failure caused by accidental touch and improve the adsorption stability of the suction cup support seat body.

[0051] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0052] It should be noted that the "fixed to" and "connected to" herein can be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0053] Embodiment 1:

[0054] As Figures 1-3 shown, a suction cup bracket base 100 provided in this embodiment includes a base body 100. A first cover body 500 is provided on the base body 100. The first cover body 500 is fixedly connected to the base body 100 and forms a cavity with the base body 100. An installation groove 130 is provided at the top of the base body 100. A hollow rotating member 300 is provided on the installation groove 130. The rotating member 300 can rotate relative to the base body 100, and at least one climbing track 310 is formed at the top of the rotating member 300. In this embodiment, it is preferably set that two climbing tracks 310 are arranged oppositely.

[0055] A connecting rod 400 is provided on the base body 100. The connecting rod 400 penetrates through the base body 100, and the bottom of the connecting rod 400 is connected with a suction cup 200, and the top penetrates through the rotating member 300.

[0056] A pin shaft 410 is provided on the connecting rod 400. The pin shaft 410 is erected on the rotating member 300, and the end of the pin shaft 410 extends into the climbing track 310.

[0057] The pin shaft 410 can be integrally formed with the connecting rod 400; alternatively, a perforation can be provided on the connecting rod 400, and the pin shaft 410 is press-fitted in the perforation.

[0058] On the rotating member 300, a groove body is provided, and the bottom groove wall of the groove body is arc-shaped to form the climbing track 310.

[0059] On the climbing track 310, a first limit point 311 and a second limit point 312 are provided. The height of the first limit point 311 is higher than that of the second limit point 312. The pin shaft 410 is displacement-limitedly matched with the first limit point 311 or the second limit point 312 within the climbing track 310.

[0060] On the first cover body 500, a swing groove 510 communicating with the internal cavity is provided. On the outer wall of the rotating member 300, a swing rod 320 is provided. The end of the swing rod 320 passes through the swing groove 510 and extends outside the first cover body 500. During actual use, rotating the swing rod 320 can drive the rotating member 300 to rotate on the seat body 100, and the rotation angle is limited by the angle between the swing rod 320 and the two end groove walls of the swing groove 510.

[0061] Moreover, at least one rubber ring 350 is provided at the bottom of the rotating member 300. When the rotating member 300 is arranged in the installation groove 130, the rubber ring 350 abuts against both the installation groove 130 and the rotating member 300, which is used to increase the friction force when the rotating member 300 rotates.

[0062] A return spring 700 is sleeved on the outer wall of the connecting rod 400. One end of the return spring 700 abuts against the suction cup 200, and the other end abuts against the rotating member 300, which is used to assist the connecting rod 400 and the suction cup 200 to return to their original positions.

[0063] Specifically, the rotating member 300 rotates under the drive of the swing rod 320, and the pin shaft 410 climbs relatively along the climbing track, entering from the second limit point 312 with a lower height into the first limit point 311 with a higher height. After the suction cup 200 is lifted to form a vacuum negative pressure cavity to adsorb an object, the connecting rod 400 drives the suction cup 200 to lift and compress the return spring 700; when the suction cup 200 needs to release the vacuum negative pressure of the vacuum negative pressure cavity to separate from the object, the rotating member 300 rotates reversely and returns to its original position under the reset drive of the swing rod 320, and the elastic force of the return spring 700 assists the suction cup 200 and the connecting rod 400 to return to their original positions.

[0064] A first limiting rod 110 is provided at the top of the base 100, and a first arc-shaped limiting groove 330 is provided on the first cover 500. The first limiting rod 110 passes through the first arc-shaped limiting groove 330 and is in limiting cooperation with the two end groove walls of the first arc-shaped limiting groove 330.

[0065] The suction cup 200 described in this embodiment preferably adopts any one of a TPE suction cup, a silica gel suction cup or a PVC suction cup.

[0066] A connecting rod structure is hinged at the top of the first cover 500 for connecting and fixing a bracket for a mobile phone, other intelligent devices or a photographic device.

[0067] The using steps of the suction cup bracket base 100 in this embodiment are as follows:

[0068] (1) When the suction cup bracket base 100 needs to be adsorbed on an object:

[0069] Press the suction cup 200 against the object to be adsorbed.

[0070] Dial the swing rod 320 to swing within the range of the swing groove 510 until the pin shaft 410 disengages from the second limit point 312 and enters the first limit point 311.

[0071] During this process, since the rotating member 300 rotates on the base 100 and the positions of the connecting rod 400 and the pin shaft 410 on the connecting rod 400 remain unchanged, the pin shaft 410 relatively climbs along the climbing track 310, driving the connecting rod 400 to drive the suction cup 200 to deform and lift, and at the same time compressing the return spring 700, forming a vacuum negative pressure cavity between the suction cup 200 and the object to adsorb on the object.

[0072] (2) When the suction cup bracket base 100 needs to be separated from the adsorbed object:

[0073] Dial the swing rod 320 in the reverse direction until the pin shaft 410 disengages from the first limit point 311 and enters the second limit point 312.

[0074] During this process, the rotating member 300 relatively descends along the climbing track 310 to reset and cooperate with the elastic force of the return spring 700 to drive the connecting rod 400 and the suction cup 200 to reset, releasing the vacuum negative pressure in the vacuum negative pressure cavity, so that the adsorption of the suction cup 200 fails and is separated from the object.

[0075] Embodiment 2:

[0076] As Figures 4-7As shown, the second cover 600 that can rotate relative to the base 100 is provided on the base 100 in this embodiment. A connecting sleeve 610 is provided on the second cover 600. The connecting sleeve 610 is sleeved on the rotating member 300, and a connecting groove 611 is provided on the inner wall of the connecting sleeve 610. A connecting convex block 340 is provided on the outer wall of the rotating member 300. When the connecting sleeve 610 is sleeved on the rotating member 300, the connecting convex block 340 is inserted into the connecting groove 611, so that the second cover 600 drives the rotating member 300 to rotate when rotating relative to the base 100, which can better prevent accidental contact with the detachment structure of the suction cup 200.

[0077] Correspondingly, at least one second limiting rod 120 is provided on the top surface of the base 100, and a second arc-shaped limiting groove 620 corresponding to the second limiting rod 120 is provided at a position on the second cover 600 on the side of the connecting sleeve 610. The second limiting rod 120 passes through the second arc-shaped limiting groove 620 and is in limiting cooperation with the two end groove walls of the second arc-shaped limiting groove 620.

[0078] A connecting rod structure is hinged to the top of the second cover 600 for connecting and fixing a bracket for a mobile phone, other intelligent devices or photographic devices.

[0079] Other structures of this embodiment are the same as those of Embodiment 1 and will not be repeated here.

[0080] The using steps of the suction cup bracket base 100 in this embodiment:

[0081] (1) When the suction cup bracket base 100 needs to be adsorbed on an object:

[0082] Press the suction cup 200 against the object to be adsorbed.

[0083] Rotate the second cover 600 to drive the rotating member 300 to rotate until the pin shaft 410 disengages from the second limit point 312 and enters the first limit point 311.

[0084] In this process, the pin shaft 410 moves relatively upward along the climbing track 310, drives the connecting rod 400 to drive the suction cup 200 to deform upward, and at the same time compresses the return spring 700, forming a vacuum negative pressure cavity between the suction cup 200 and the object to adsorb on the object.

[0085] (2) When the suction cup bracket base 100 needs to be detached from the adsorbed object:

[0086] Rotate the second cover 600 in the reverse direction until the pin shaft 410 disengages from the first limit point 311 and enters the second limit point 312.

[0087] In this process, the rotating member 300 rotates relative to the base body 100 and is reset in cooperation with the elastic force of the return spring 700 to drive the connecting rod 400 and the suction cup 200 to be reset, releasing the vacuum negative pressure in the vacuum negative pressure chamber, so that the adsorption of the suction cup 200 fails and disengages from the object.

[0088] According to the disclosure and teachings of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention.
