本发明的组装：附图4中的箭头指的是吸盘吸附的过程；组装时如图4所示，由上到下依次是外壳1、定位圈4、主体支架2、吸片3；使吸片3上的挂齿32穿过主体支架2上的卡孔25，挂齿32的内齿321卡置在卡孔25上边缘形成卡接，然后将定位圈4套在主体支架2的内圈23上，再将外壳1扣合在外圈22上，外壳1上的止脱齿13通过外圈22上的脱齿让位槽26向齿环槽28滑去，止脱齿13继续向下克服绊舌齿27的阻力，划入齿环槽28形成稳定的卡接结构，避免松脱；扣合的同时将拨齿12对准定位圈4上的拨孔41并***；扣合完毕后，主体支架2中心的固定柱24与外壳1上的让位孔11重合。完成安装。Assembly of the present invention: the arrow in Fig. 4 refers to the process of sucking the suction cup; as shown in Fig. 4, the outer casing 1, the positioning ring 4, the main body bracket 2, and the suction piece 3 are sequentially arranged from top to bottom; The hanging teeth 32 on the sheet 3 pass through the card holes 25 in the main body bracket 2, and the inner teeth 321 of the hanging teeth 32 are snapped on the upper edges of the card holes 25 to form a snap, and then the positioning ring 4 is placed on the inner ring 23 of the main body bracket 2. Then, the outer casing 1 is fastened to the outer ring 22, and the retaining teeth 13 on the outer casing 1 are slid away from the tooth ring groove 28 by the tooth removing groove 26 on the outer ring 22, and the retaining teeth 13 continue to overcome the tongue downward. The resistance of the tooth 27 is divided into the ring groove 28 to form a stable snap-fit structure to avoid loosening; the buckle 12 is aligned with the dial hole 41 of the positioning ring 4 and inserted while being engaged; after the fastening is completed, the main body bracket The center fixing post 24 coincides with the retaining hole 11 on the outer casing 1. finish installation.
本发明的工作过程，参考图6和图7的细节结构，安装时使拨台42和外齿322在竖直方向不重叠，手握外壳1将吸片3的吸板31按压在光滑的墙面上，旋拧外壳1，使 拨齿12拨动定位圈4随之旋转，这样拨台42和外齿322借助设置的倾斜面发生接触；此时外齿322受到力向径向提升，而其反作用力通过定位圈4施加在主体支架2上，主体支架2的底板21向下压置吸板31，与此同时吸板31中心部位被挂齿32提起，这样吸板31与墙面之间形成真空，完成基本吸附。The working process of the present invention, with reference to the detailed structure of Figs. 6 and 7, is such that the dial 42 and the external teeth 322 do not overlap in the vertical direction during installation, and the handle housing 1 presses the suction plate 31 of the suction pad 3 against the smooth wall. On the surface, screw the outer casing 1 so that The tooth 12 is moved with the positioning ring 4 to rotate, so that the dial 42 and the external tooth 322 are contacted by the disposed inclined surface; at this time, the external tooth 322 is radially urged by the force, and the reaction force is applied through the positioning ring 4 On the main body bracket 2, the bottom plate 21 of the main body bracket 2 presses the suction plate 31 downward, and at the same time, the central portion of the suction plate 31 is lifted by the hanging teeth 32, so that a vacuum is formed between the suction plate 31 and the wall surface to complete the basic adsorption.
外壳1继续旋转，使外齿322越过止退棱44，到达限位筋43和止退棱44之间，此时完成吸附。吸板31与底板21的接触位置设置凸圈，增加压力效果，凸圈位于吸板31的外延。The outer casing 1 continues to rotate so that the outer teeth 322 pass over the retaining ribs 44 to between the retaining ribs 43 and the retaining ribs 44, at which point the suction is completed. The contact position of the suction plate 31 and the bottom plate 21 is provided with a bead to increase the pressure effect, and the bead is located at the extension of the suction plate 31.
外壳1的旋钮方向是根据拨台42和外齿322的相对倾斜方向确定的，如附图6、7设置，就是按照图4中的方向旋拧。The direction of the knob of the outer casing 1 is determined according to the relative inclination direction of the dial 42 and the outer teeth 322, as shown in Figs. 6, 7 and is screwed in the direction of Fig. 4.
本方案中提到的内侧、外侧指的是吸盘的部件都是圆形，面向圆心一侧是内侧，另一侧是外侧。The inner side and the outer side mentioned in the present scheme mean that the components of the suction cup are all circular, the inner side facing the center of the circle is the inner side, and the other side is the outer side.
实施例一，如附图1-3所示，与实施例二区别之处在于，拨齿12是三个，定位圈4外壁设置有三个弹片45，每个弹片45末端外侧都设置一个卡位凸起46，外圈22的内壁设置三个凸棱29与弹片45上的卡位凸起46对应，并且内齿321设置在挂齿32的两侧，挂齿32顶部的内齿321安装后卡置在卡孔25顶部两侧。并且限位筋43与拨台42一体成型，结构紧凑可靠稳定，组装完成后弹片45与卡位凸起46抵触。The first embodiment, as shown in FIG. 1-3, is different from the second embodiment in that the teeth 12 are three, and the outer wall of the positioning ring 4 is provided with three elastic pieces 45, and one end of each end of the elastic piece 45 is provided with a card position. The inner wall of the outer ring 22 is provided with three ribs 29 corresponding to the latching projections 46 on the elastic piece 45, and the inner teeth 321 are disposed on both sides of the hanging teeth 32. The inner teeth 321 at the top of the hanging teeth 32 are mounted and then placed. On both sides of the top of the card hole 25. Moreover, the limiting rib 43 is integrally formed with the dial 42 and has a compact and reliable structure. After the assembly is completed, the elastic piece 45 is in contact with the latching projection 46.
其余的机构和安装于实施例二相同，在使用时，旋拧外壳1时弹片45会在卡位凸起46上滑动，当弹片45上的卡位凸起46滑过凸棱29会有咔哒声，这样预示着外齿322的前端与限位筋43抵触，并且外齿322已经滑过止退棱44，这样避免旋转过位用力过猛导至的损坏。The rest of the mechanism is the same as that of the second embodiment. In use, when the outer casing 1 is screwed, the elastic piece 45 will slide on the latching projection 46. When the latching projection 46 on the elastic piece 45 slides over the rib 29, there will be a flaw. The sound indicates that the front end of the outer tooth 322 is in contact with the limiting rib 43, and the outer tooth 322 has slid over the retaining rib 44, so as to avoid the damage caused by the excessive rotation force.
本技术方案中的内齿321无论在内侧或是两侧，都是起到在吸盘不受力时防止吸片3松脱，在实施例一中内齿321在挂齿32两侧，此时在卡孔25上边缘固定柱24一侧设 置挡块251，使用时挂齿32与卡孔25卡接完成后，挂齿32上部分内侧与挡块251对应，可以避免挂齿32顶端受力变形向固定柱24一侧偏移，但是挡块251的设置会使挂齿32始终保持竖直运动，避免外齿322脱扣。The inner teeth 321 in the technical solution are used to prevent the suction piece 3 from being loosened when the suction cup is unstressed, in the inner side or the two sides. In the first embodiment, the inner teeth 321 are on both sides of the hanging teeth 32. The upper edge of the card hole 25 is fixed on the side of the column 24 When the latching block 251 is engaged with the latching hole 25 in use, the inner side of the upper portion of the hanging tooth 32 corresponds to the stopper 251, so that the top end of the hanging tooth 32 can be prevented from being deformed toward the side of the fixing post 24 by the force deformation, but the blocking block 251 The setting will keep the hanging teeth 32 in vertical motion and avoid the external teeth 322 from tripping.
实施例一、二中的在外壳1外侧壁设置多组竖直的外观筋14，一个是美观，一个是防滑。In the first and second embodiments, a plurality of sets of vertical appearance ribs 14 are disposed on the outer side wall of the outer casing 1, one is beautiful and the other is non-slip.
以上显示和描述了本发明的基本原理和主要特征。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。 The basic principles and main features of the present invention have been shown and described above.
