A knob type suction cup support convenient to disassemble and replace

Abstract

This utility model discloses a knob-type suction cup bracket that is easy to disassemble and replace. It includes a bracket cover, a suction cup assembly, a fixing assembly, a knob, and upper and lower movable parts. The suction cup assembly and the bracket body can be separated and quickly connected, making disassembly and assembly convenient. In this patent, a gap is cleverly reserved in the pull-pressure concave ring of the pull-pressure head. When the pull-pressure head is inserted into the pull-pressure assembly, the pull-pressure assembly is pre-entered into the limiting lock groove to lock the pull-pressure clamping part. Thus, when the upper and lower movable parts are driven upward by the knob, they can first eliminate the gap and then pull the pull-pressure head upward, thereby pulling the suction cup below to complete the vacuuming. When the upper and lower movable parts are driven downward by the knob, the pull-pressure assembly disengages from the limiting lock groove and moves downward until the gap is re-established and continues to push the pull-pressure head downward. Thus, the bracket body and the suction cup assembly can be separated. The bracket cover in this patent can rotate relative to the bracket body and has a damped ticking stop rotation.

Description

Technical Field

[0001] This utility model relates to the field of suction cup mobile phone holder technology, and in particular to a knob-type suction cup holder that is easy to disassemble and replace. Background Technology

[0002] Currently, in most suction cup holder products, the suction cup and the holder body cannot be separated. This limits the application scenarios of the holder body located at the top of the suction cup holder and cannot meet the needs of multiple scenarios. In some applications, such as when users want to use the holder body without the suction cup as a base for movie viewing, the suction cup becomes a burden due to the inconvenience of taking it out and putting it back in. If users want to attach the holder directly to metal furniture surfaces (such as refrigerators), this cannot be done with the suction cup attached. Switching between magnetic and non-magnetic phone holders is also particularly troublesome if done using the traditional ball joint connector. Therefore, separating the suction cup from the holder body becomes essential. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a knob-type suction cup bracket that is easy to disassemble and replace, so as to solve the technical problems mentioned in the background art.

[0004] To solve the technical problem, this utility model adopts the following technical solution: A knob-type suction cup holder for easy disassembly and replacement includes: A bracket cover, wherein the bracket cover is provided with a connecting portion; A suction cup assembly, which is located below the bracket cover and is equipped with a suction cup pull rod, wherein the suction cup pull rod is provided with a pull head; A fixing component is located between the bracket cover and the suction cup assembly and includes an upper fixing member and a lower fixing member. A guide rod assembly is also provided between the upper fixing member and the lower fixing member. A knob, located between the bracket cover and the suction cup assembly, having a rotating part and a driving part, wherein a driving slide is provided in the driving part; The upper and lower movable parts are located between the upper fixed part and the lower fixed part, and have a guide groove and a driving block. The guide groove is in a limiting fit with the guide rod assembly, and the driving block is in a sliding fit with the driving slide. The upper and lower movable parts are also provided with a tension and compression assembly. The pull-press head can cooperate with the pull-press assembly to lock and unlock. When the pull-press head is pulled upward, the suction cup assembly is vacuumed to achieve adsorption. When the pull-press head is moved downward to release, the suction cup assembly is devastated and can be separated from the pull-press assembly.

[0005] Specifically, the tension-compression assembly includes a tension-compression clamping member and a tension-compression hole. The tension-compression hole passes through the upper and lower movable members. The tension-compression clamping member is located at the upper end of the tension-compression hole. The tension-compression head is provided with a tension-compression concave ring. A cover fixing member is provided below the bracket cover. A limiting locking groove is provided on one side of the cover fixing member. The tension-compression head can pass through the tension-compression hole and clamp tightly with the tension-compression clamping member. The tension-compression clamping member has a release characteristic. When the tension-compression clamping member moves upward with the upper and lower movable members and enters the limiting locking groove, the tension-compression head located inside the tension-compression clamping member is clamped by the tension-compression clamping member and cannot be released. When the tension-compression clamping member moves downward with the upper and lower movable members and disengages from the limiting locking groove, the tension-compression head located inside the tension-compression clamping member can be released from the tension-compression clamping member.

[0006] Specifically, the suction cup assembly includes a suction cup body, a sealing adhesive, and a pull rod. The inner side of the suction cup body is provided with a pre-embedded groove. The bottom end of the pull rod is pre-embedded in the pre-embedded groove and the upper end extends upward to form a pull head. The sealing adhesive is attached to the bottom of the suction cup body. The side of the suction cup body is also provided with an unlocking ear.

[0007] Specifically, the tensioning clamping component consists of several tensioning sheets arranged in a circle. Each set of tensioning sheets has a pressure block on its inner side. The pressure block can cooperate with the tensioning concave ring, and the longitudinal height of the tensioning concave ring is greater than the longitudinal height of the pressure block, so that there is a gap between the pressure block and the upper end face of the tensioning concave ring when the suction cup assembly is in a non-adsorption state.

[0008] Specifically, the drive slide includes an inlet area, a sliding area, and a locking area, with the heights of the inlet area, sliding area, and locking area decreasing sequentially. The inlet area is provided with an engagement part, the locking area is provided with a locking part, and the drive block is provided with a locking groove corresponding to the locking part.

[0009] Specifically, the cover fixing component includes a shaft rotating part and a seat rotating part. The upper fixing component is provided with a first through groove, and a first annular groove is provided on the inner side of the first through groove. A damping tooth is provided in the first annular groove. The shaft rotating part passes through the first through groove, and the seat rotating part is engaged with the first annular groove. A damping elastic element is provided at the position of the seat rotating part to engage with the damping tooth. The cover fixing component is fixed to the bracket cover vertically. By rotating the bracket cover, the cover fixing component can be rotated in a damped ticking motion.

[0010] Specifically, the upper end of the suction cup assembly is provided with an annular positioning locking tooth, and the lower end of the lower fixing member is provided with an annular positioning locking groove. When the suction cup rod of the suction cup assembly is pulled upward, the annular positioning locking tooth engages with the annular positioning locking groove upward to prevent the upper bracket component from rotating with the suction cup assembly.

[0011] Specifically, the engaging part is an elastic extension extending towards the center from the inner sidewall of the locking area. The elastic extension has an elastic protrusion on the side facing the center. When the elastic protrusion engages with the engaging groove of the drive block, the knob is locked in the unlocked position.

[0012] It also includes a magnetic phone holder, which includes a magnetic base and a rotating arm. One end of the rotating arm is rotatably connected to the magnetic base through a first damping mechanism, and the other end is connected to the connecting part through a second damping mechanism. The magnetic base includes a magnetic body, an annular magnet, and a cover. The inner side of the magnetic body is provided with an annular insertion groove, and the side wall of the annular insertion groove is provided with several locking mechanisms. Each locking mechanism includes an inlet groove and a locking groove. The outer side of the annular magnet is provided with several locking blocks corresponding to the locking mechanism. The locking blocks enter from the inlet groove, rotate, and then enter the locking groove to complete the installation of the annular magnet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) In this patent, the suction cup assembly and the bracket body can be separated and quickly connected, making disassembly and assembly convenient. After separation, it is easy for users to change to different application scenarios. (2) In this patent, a gap is cleverly reserved in the pull-pressing concave ring of the pull-pressing head, so that when the pull-pressing head is inserted into the pull-pressing assembly, the pull-pressing assembly is pre-entered into the limiting lock groove to lock the pull-pressing clamping part. Thus, when the upper and lower movable parts are driven to move upward by the knob, they can first eliminate the gap and then pull the pull-pressing head to move upward, thereby pulling the suction cup below to complete the vacuuming. When the upper and lower movable parts are driven to move downward by the knob, the pull-pressing assembly is disengaged from the limiting lock groove and moves downward until the gap is re-established and continues to push the pull-pressing head downward. Thus, the bracket body and the suction cup assembly can be separated.

[0014] (3) The bracket cover in this patent can rotate relative to the bracket body and has a damped ticking position for rotation.

[0015] (4) This patent also provides a magnetic mobile phone holder, which can be fixed in any position of the magnetic base by means of the swing arm. When installing the magnetic ring, it is also installed by overall screwing. The installation is simple and stable and not easy to fall off. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] refer to Figures 1 to 18 : This embodiment discloses a knob-type suction cup holder that is easy to disassemble and replace, including a holder body 10A and a suction cup assembly 20A. The holder body 10A includes a holder cover 1, a fixing component 3, a knob 4, and an up-and-down movable component 5. The holder cover 1 is provided with a connecting part 11 for connecting a mobile phone holder / magnetic mobile phone holder 7. The connecting part 11 can be a ball joint, a hinge joint, or other connecting mechanism. The suction cup assembly 20A is located below the holder cover 1 and is equipped with a suction cup pull rod 21. The suction cup pull rod 21 is provided with a pull head 211. By pulling the pull head 211 of the suction cup pull rod 21, the suction cup can be pulled up from the middle, thereby completing the vacuuming operation. The fixing component 3 is located between the holder cover 1 and the suction cup assembly 20A. The space between 0A includes an upper fixing member 31 and a lower fixing member 32. A guide rod assembly 301 is also provided between the upper fixing member 31 and the lower fixing member 32. The guide rod assembly 301 is located between the upper fixing member 31 and the lower fixing member 32. Simultaneously, the inner side of the guide rod assembly 301 also serves as the position for the fixing bolts of the upper fixing member 31 and the lower fixing member 32. Preferably, the guide rod assembly 301 of the lower fixing member 32 is sleeved onto the guide rod assembly 301 of the upper fixing member 31, forming a complete guide rod assembly 301. Through the spacing and guide rail action of the guide rod assembly 301, a gap is formed between the upper fixing member 31 and the lower fixing member 32. This gap serves as the stroke for the vertical displacement of the upper and lower movable member 5. The knob 4 is located on the bracket cover 1 and... The suction cup assembly 20A includes a rotating part 4A and a driving part 4B. The rotating part 4A is located outside the knob 4 and is usually square or round, with unlock and lock indicators. The driving part 4B is designed as a through groove that passes through the knob 4, making the knob 4 a ring-shaped component. A driving slide 41 is provided on the inner wall of the driving part 4B. The driving slide 41 is distributed along the side wall of the through groove inside the knob 4, generally in a spiral direction or with a vertical height difference design. Usually, multiple sets of driving slides 41 are provided in one through groove, and the multiple sets of driving slides 41 are arranged sequentially. The upper and lower movable parts 5 are located between the upper fixed part 31 and the lower fixed part 32, and have a guide groove 51 and a driving block 5. 2. The guide groove 51 is limited to the guide rod assembly 301, and the drive block 52 is slidably engaged with the drive slide 41. The drive block 52 is embedded in the drive slide 41. When the knob 4 is rotated, the sliding engagement between the drive block 52 and the drive slide 41 causes the rotation of the knob 4 to drive the upper and lower movable parts 5 to perform longitudinal displacement, that is, to convert horizontal rotation into longitudinal displacement. The upper and lower movable parts 5 are also provided with a tensioning assembly 53. The tensioning head 211 can cooperate with the tensioning assembly 53 to lock and unlock. When the tensioning head 211 is pulled up, the suction cup assembly 20A is vacuumed to achieve adsorption. When the tensioning head 211 is released down, the suction cup assembly 20A is devastated and can be separated from the tensioning assembly 53.

[0019] The tension-compression assembly 53 includes a tension-compression clamping member 531 and a tension-compression hole 532. The tension-compression hole 532 passes through the upper and lower movable members 5. The tension-compression clamping member 531 is located at the upper end of the tension-compression hole 532. The tension-compression head 211 is provided with a tension-compression concave ring 211a. A cover fixing member 6 is provided below the bracket cover 1. A limiting locking groove 601 is provided on one side of the cover fixing member 6. The tension-compression head 211 can pass through the tension-compression hole 532 and clamp tightly with the tension-compression clamping member 531. The tension-compression clamping member 531 has a release characteristic. When the tension-compression clamping member 531 moves upward with the upper and lower movable members 5 and enters the limiting locking groove 601, the tension-compression head 211 located inside the tension-compression clamping member 531 is tensioned and clamped. If the clamping member 531 is stuck and cannot be released, continue to turn the knob 4. The linkage will drive the pulling head 211 to pull upward, which can complete the vacuuming work of the suction cup assembly 20A. When the pulling clamping member 531 moves down with the upper and lower moving parts 5 and disengages from the limiting lock groove 601, the pulling clamping member 531 becomes elastic because it is no longer restrained by the limiting lock groove 601. It can be stretched open and formed a release characteristic. The pulling head 211 located inside the pulling clamping member 531 can be released from the pulling clamping member 531. At this time, the bracket body 10A can be separated from the suction cup assembly 20A by hand. Thus, different bracket bodies 10A can be replaced to adapt to different application scenarios.

[0020] Specifically, the suction cup assembly 20A includes a suction cup body 22, sealing adhesive 23, and a suction cup pull rod 21. The inner side of the suction cup body 22 has a pre-embedded groove 221. The bottom end of the suction cup pull rod 21 is pre-embedded in the pre-embedded groove 221, and its upper end extends upward to form a pull head 211. The sealing adhesive 23 is attached to the bottom of the suction cup body 22. One side of the suction cup body 22 also has an unlocking ear 222. Here, the sealing adhesive 23 is located at the bottom of the suction cup body 22, and it has sealing and adhesive properties. In some scenarios, such as the center console of a car, it does not have a light-sensitive surface. When the suction cup is slippery and the suction cup adsorption effect is poor, the first attachment point is formed by the sealing adhesive 23 at the bottom. A part of the area between the attachment point and the suction cup body 22 is reserved for the suction cup to be pulled upward. The suction cup assembly 20A serves as the second adsorption point, which is equivalent to having a double fixing mechanism. Once the sealing adhesive 23 is firmly attached to a certain area, it is usually not replaced frequently for the sake of the aesthetics of the attached part. Therefore, separating the upper support body 10A becomes particularly important. The traditional suction cup assembly 20A cannot be separated from the support body 10A, which cannot be adapted to this application scenario.

[0021] Specifically, the tension-grip clamping member 531 is composed of several tension plates 531a arranged in a circle. Each set of tension plates 531a has a pressure block 532b on its inner side. The pressure block 532b can cooperate with the tension-grip recess 211a, and the longitudinal height of the tension-grip recess 211a is greater than the longitudinal height of the pressure block 532b. This ensures that when the suction cup assembly 20A is in a non-adsorption state, there is a gap 1a between the pressure block 532b and the upper end face of the tension-grip recess 211a. Due to this gap 1a, when the suction cup assembly 20A is in a non-adsorption state, the tension-grip clamping member 531 lacks an upper end face. The restraint at the end allows direct removal of the bracket body 10A to separate the tension clamp 531 from the tension head 211. When the knob 4 rotates, it causes the upper and lower movable parts 5 to move upward. When the upper end of the tension clamp 531 enters the limiting lock groove 601, the pressure block 532b on the tension clamp 531 reaches the upper end face of the tension concave ring 211a. That is, the pressure block 532b and the tension concave ring 211a reach the uppermost end of the gap 1a (or it can be understood as eliminating the gap 1a). Therefore, when the upper and lower movable parts 5 continue to move upward, the pressure block 532b continues to lift the tension head 211 upward, thus achieving... The suction cup lever 21 is continuously pulled upwards until the suction cup is vacuumed and adsorption is complete. At this point, the action of the knob 4 is called locking. The rotation stroke of the knob 4 is limited by the cooperation stroke between the drive block 52 and the drive slide 41, and also by the stroke of the gap 1a between the upper fixing member 31 and the lower fixing member 32. If any point reaches the end, the turning action of the knob 4 is restricted. In the opposite action, the knob 4 rotates in the opposite direction, the upper and lower moving parts 5 move down, and the linked tension clamping member 531 disengages from the limiting lock groove 601. The suction cup lever 21 itself is subjected to suction. The downward pull of the disc body 22 will cause the tension clamp 531 to move downward. When the pressure block 532b of the tension clamp 531 reaches the lower end face of the tension concave ring 211a, the gap 1a between the upper end face of the tension concave ring 211a and the upper end face of the pressure block 532b reappears. As a result, the tension plate 531a of the tension clamp 531 is no longer restrained by the limiting locking groove 601. The tension head 211 can be pulled out from the tension clamp 531. The pulling action can directly grab the knob 4 to pull the entire bracket body 10A upward, completing the separation of the bracket body 10A from the suction cup assembly 20A.

[0022] Specifically, the drive slide 41 includes an entrance area 411, a sliding area 412, and a locking area 413. The heights of the entrance area 411, the sliding area 412, and the locking area 413 decrease sequentially. The entrance area 411 has a fitting portion 411a, and the locking area 413 has a locking portion 413a. The drive block 52 has a locking portion 413a corresponding to the locking portion 413a. Here, the fitting portion 411a of the entrance area 411 serves as the initial position of the drive block 52 when it enters the drive slide 41. There is a certain height difference between the fitting portion 411a and the sliding area 412. The joint forms a slope. When the knob 4 is in the locked state, the drive block 52 is located at the fitting part 411a of the entrance area 411. Due to the height difference between the fitting part 411a and the sliding area 412, the knob 4 will not actively unlock, and the suction cup assembly 20A will not loosen when it is in the suction state. When unlocking is required, the knob 4 is manually rotated, causing the drive block 52 to disengage from the fitting part 411a and enter the sliding area 412. As the knob 4 continues to rotate, the drive block 52 reaches the locking area 413 and is finally engaged by the engaging groove 521 of the drive block 52 with the elastic protrusion 413b (e.g., Figure 9 When the elastic protrusion 413b engages with the engaging groove 521 of the drive block 52, the knob 4 is locked in the unlocked position, thus completing the unlocking process. At this time, the suction force of the suction cup assembly 20A gradually decreases until the suction is released. Since the groove surface of the engaging groove 521 is set in an arc shape, when a person rotates the knob 4 in the opposite direction with a little force, the unlocked state can be released and the next locking cycle can be entered (the locking here is the suction cup assembly vacuuming and the unlocking is the release of the suction cup assembly). It should be understood that the drive block 52 itself does not rotate. It is due to the rotation of the knob 4 that the arrival or reaching here is the movement of the drive slide 41 of the knob 4.

[0023] Specifically, to achieve rotation between the faceplate bracket and the fixed component 3, the faceplate fixing member 6 includes a shaft rotating part 61 and a seat rotating part 62. The upper fixing member 31 is provided with a first through groove 311, and the inner side of the first through groove 311 is provided with a first annular groove 312. The first annular groove 312 is provided with a damping tooth 312a. The shaft rotating part 61 passes through the first through groove 311, and the seat rotating part 62 is engaged with the first annular groove 312. The seat rotating part 62 is provided with a damping elastic element 621 that engages with the damping tooth 312a to achieve elastic damping. The faceplate fixing member 6 is fixed vertically to the bracket faceplate 1. Preferably, the damping elastic element 621 is made of materials such as spring beads or elastic protrusions. Rotating the bracket faceplate 1 can cause the faceplate fixing member 6 to rotate in a damped ticking motion, which improves the rotation feel and lets the user know approximately how many angles or how many stops have been rotated.

[0024] Specifically, to prevent rotation between the suction cup and the support body 10A during the adsorption state (in some cases, when the user pulls the upper support cover 1, the support body 10A may rotate relative to the suction cup assembly 20A, which can easily damage the seal of the suction cup assembly 20A), the upper end of the suction cup assembly 20A is provided with an annular positioning locking tooth 222, and the lower end of the lower fixing member 32 is provided with an annular positioning locking groove 321. When the suction cup pull rod 21 of the suction cup assembly 20A is pulled upward, the annular positioning locking tooth 222 engages with the annular positioning locking groove 321, preventing rotation between the upper support component and the suction cup assembly 20A. (See reference...) Figure 1 As shown, both the annular positioning locking teeth 222 and the annular positioning locking grooves 321 are distributed in a circular array.

[0025] refer to Figure 10 The images, from left to right, are the first, second, third, and fourth images. The first image shows knob 4 in the unlocked state (same as above). Figure 15 The second image shows knob 4 locked at a 22.5-degree angle (same as above). Figure 16 The third image shows knob 4 locked at a 45-degree angle (same as above). Figure 17 The fourth image shows the knob locked at 90 degrees. Of course, this angle can be adjusted according to the travel of the drive slide. Figure 10 It is a two-way indicator, meaning that the unlocking process of knob 4 can be done from right to left.

[0026] Specifically, it also includes a magnetic phone holder 7, which includes a magnetic base 71 and a rotating arm 72. One end of the rotating arm 72 is rotatably connected to the magnetic base 71 via a first damping mechanism 701, and the other end is connected to the connecting part 11 via a second damping mechanism 702. The magnetic base 71 includes a magnetic body 711, an annular magnet 712, and a cover 713. The inner side of the magnetic body 711 is provided with an annular groove 711a, and the side wall of the annular groove 711a is provided with several locking mechanisms 7A. Each locking mechanism 7A includes an inlet groove 7A1 and a locking groove 7A2. The outer side of the annular magnet 712 is provided with several locking blocks 71 corresponding to the positions of the locking mechanisms 7A. 2a. The locking block 712a enters the locking groove 7A2 from the inlet groove 7A1 and rotates to complete the installation of the annular magnet 712. Since the annular magnet 712 is made as a single piece, the trouble of assembling each piece individually is eliminated. Here, it is only necessary to align the locking block 712a of the annular magnet 712 with the inlet groove 7A1 of the locking mechanism 7A and insert it, then rotate it to allow the locking block 712a to enter the locking groove 7A2, and then complete the installation. After the installation is completed, the cover 713 is installed to complete the installation of this magnetic mobile phone holder 7. As mentioned above, the first damping mechanism 701 and the second damping mechanism 702 adopt the combination of bolts and rubber pads in the prior art. After the bolts are tightened, the presence of the rubber pads forms rotational damping.

[0027] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
