Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, and more specifically, to a suction cup device and suction cup holder that are easy to install. Background Technology

[0002] In daily life, sometimes it's necessary to hang or temporarily place items on the walls of rooms, kitchens, and bathrooms, but these locations are inconvenient or unsuitable for nailing. Suction cup hangers can effectively solve this problem. However, existing rotary press-type suction cup devices suffer from inconvenient production and installation. There are installation limitations between the suction cup body and the pin; the pin must be inserted only after the suction cup body is installed. Because the pin is small, internal parts can easily obstruct the worker's insertion, causing friction with fingers and making the process inconvenient. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides an easy-to-install suction cup device, comprising a suction cup body, a mounting base, and a knob. The front and rear ends of the mounting base are respectively connected to the knob and the suction cup body. A pin is connected to the suction cup body. The mounting base has an installation port. The knob has a through-mounting part. The inner wall of the mounting part has a guide groove connecting the front and rear ends. The end of the pin is slidably connected to the guide groove. The mounting part can undergo elastic deformation so that the pin passes through the installation port and the mounting part in sequence and abuts against the front end of the mounting part.

[0004] Optionally, the side wall of the mounting part is provided with a gap, which allows the mounting part to undergo elastic deformation when the pin passes through the mounting part.

[0005] Optionally, the width of the guide groove gradually decreases from back to front to limit the sliding trajectory of the pin.

[0006] Optionally, the suction cup body is provided with a connecting seat, and the outer wall of the pin is provided with knurled stripes. The connecting seat and the pin are tightly fitted and fixed after being inserted.

[0007] Optionally, the mounting port is cross-shaped and is used to avoid the pin and the connecting seat; when in the installation state, the cross-shaped horizontal segment of the mounting port corresponds to the position of the guide groove in the front-back direction to pre-position the pin.

[0008] Optionally, the knob has an arc-shaped rotating opening, and the mounting base has a connecting post that passes through the rotating opening and is slidably connected to it.

[0009] Optionally, it also includes a top cover assembly, which has a slot and a buckle at the upper end of the connecting post. The buckle and the slot engage to fix the mounting base and the top cover assembly together.

[0010] Optionally, the mounting part is provided with a sliding arc surface, the height of which gradually increases in the front-rear direction. The pin and the sliding arc surface are slidably connected. The two ends of the sliding arc surface are respectively provided with a first groove and a second groove. The bottom end of the suction cup body is recessed inward to form an adsorption cavity. When the knob is rotated in the forward direction and pressed, the pin slides from the first groove to the second groove. The pin drives the suction cup body to move forward relative to the mounting base. The rear end of the mounting base squeezes the suction cup body to expel the air in the adsorption cavity. When the knob is rotated in the reverse direction, the pin slides from the second groove to the first groove. The pin drives the suction cup body to move backward relative to the mounting base. The rear end of the mounting base releases the suction cup body to allow air to enter the adsorption cavity.

[0011] Optionally, the bottom of the mounting base is provided with an annular rib, which abuts against the suction cup body; when the knob is rotated in the forward direction and pressed, the annular rib squeezes the suction cup body to expel the air in the suction cavity, at which time the bottom of the outer wall of the mounting base abuts against the suction cup body.

[0012] Compared to existing technologies, the easy-to-install suction cup device in this utility model, by setting a guide groove, allows the suction cup body to be installed with the pin first, and then connected to the mounting base and knob together with the pin. When the pin is inserted into the mounting part along the guide groove, it smoothly passes through the mounting part and reaches the installation position at the front end of the mounting part under the guidance of the guide groove and the slight deformation of the mounting part, reducing installation limitations and making production and assembly more convenient and faster.

[0013] In addition, this utility model provides a suction cup holder, which includes the suction cup device described above that is easy to install.

[0014] Compared with the prior art, the suction cup holder described in this utility model has the same advantages as the aforementioned easy-to-install suction cup device, which will not be repeated here. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0026] This utility model embodiment provides a suction cup device that is easy to install, combined with Figures 1 to 7 As shown, the device includes a suction cup body 1, a mounting base 2, and a knob 3. The front and rear ends of the mounting base 2 are respectively connected to the knob 3 and the suction cup body 1. A pin 11 is connected to the suction cup body 1. The mounting base 2 is provided with a mounting port 21. The knob 3 is provided with a mounting part 31 that extends through the front and rear ends. The inner wall of the mounting part 31 is provided with a guide groove 311 that connects the front and rear ends. The end of the pin 11 is slidably connected to the guide groove 311. The mounting part 31 can undergo elastic deformation so that the pin 11 passes through the mounting port 21 and the mounting part 31 in sequence and then abuts against the front end of the mounting part 31.

[0027] like Figure 1 , 4 As shown in Figure 6, in this embodiment, the end of the suction cup body 1 away from the mounting base 2 is adapted to fit against a mounting surface such as a wall. The vertical cross-section of the mounting part 31 is approximately circular, and the diameter of the mounting part 31 gradually decreases from back to front. The pin 11 is cylindrical. When the pin 11 is inserted into the mounting part 31 from back to front, the two ends of the pin 11 will press against the side wall of the mounting part 31, causing the side wall of the mounting part 31 to fold outward and undergo slight elastic deformation until the pin 11 passes through the mounting part 31.

[0028] The suction cup device of this utility model, which is easy to install, is provided with a guide groove 311, which allows the suction cup body 1 to be installed with the pin 11 first, and then connected to the mounting base 2 and the knob 3 together with the pin 11. When the pin 11 is inserted into the mounting part 31 along the guide groove 311, it passes smoothly through the mounting part 31 and reaches the installation position at the front end of the mounting part 31 under the guidance of the guide groove 311 and the slight deformation of the mounting part 31. This reduces installation limitations and makes production and assembly more convenient and faster.

[0029] Optionally, the mounting part 31 is provided with a gap 312 on its side wall. When the pin 11 passes through the mounting part 31, the gap 312 makes it easy for the mounting part 31 to undergo elastic deformation.

[0030] like Figure 4 and 6 As shown, in this embodiment, two symmetrically arranged gaps 312 are provided. The gaps 312 are used to reduce the rigidity of the mounting part 31, so that the pin 11 is less likely to be damaged when passing through the mounting part 31.

[0031] Optionally, the width of the guide groove 311 gradually decreases from back to front to limit the sliding trajectory of the pin 11.

[0032] like Figure 4 As shown, in this embodiment, two guide grooves 311 are symmetrically provided, and the two ends of the pin 11 are slidably connected to the two guide grooves 311 respectively. The rear end of the guide groove 311 is wider to facilitate the alignment of the pin 11 and its entry into the guide groove 311, and the front end of the guide groove 311 is narrower to limit the pin 11, so that the pin 11 is not easy to rotate during insertion.

[0033] Optionally, the suction cup body 1 is provided with a connecting seat 12, and the outer wall of the pin 11 is provided with knurled stripes (not shown). The connecting seat 12 and the pin 11 are inserted and tightly fitted together.

[0034] like Figure 4As shown, optionally, the mounting port 21 is cross-shaped, and the mounting port 21 is used to avoid the pin 11 and the connecting seat 12; when in the installation state, the cross-shaped horizontal section of the mounting port 21 corresponds to the guide groove 311 in the front-back direction to pre-position the pin 11 for installation. The cross-shaped vertical section of the mounting port 21 is used to avoid the mounting seat 2.

[0035] like Figure 6 and 7 As shown, optionally, the knob 3 is provided with an arc-shaped rotating opening 32, and the mounting base 2 is provided with a connecting post 22, which passes through the rotating opening 32 and is slidably connected to the rotating opening 32.

[0036] Optionally, it also includes a top cover assembly 4, which has a slot 421 and a buckle 221 at the upper end of the connecting post 22. The buckle 221 and the slot 421 are engaged to fix the mounting base 2 and the top cover assembly 4 together.

[0037] like Figure 3 As shown, in this embodiment, the top cover assembly 4 includes a first top cover 41 and a second top cover 42 that are snapped together. A slot 421 is provided on the second top cover 42, and the second top cover 42 and the mounting base 2 are fixedly connected.

[0038] Optionally, the mounting part 31 is provided with a sliding arc surface 313, the height of which gradually increases in the front-rear direction. The pin 11 and the sliding arc surface 313 are slidably connected. The two ends of the sliding arc surface 313 are respectively provided with a first groove 314 and a second groove 315. The bottom end of the suction cup body 1 is recessed inward to form an adsorption cavity 13. When the knob 3 is rotated in the forward direction and pressed, the pin 11 slides from the first groove 314 to the second groove 315. The pin 11 drives the suction cup body 1 to move forward relative to the mounting base 2. The rear end of the mounting base 2 squeezes the suction cup body 1 to expel the air in the adsorption cavity 13. When the knob 3 is rotated in the reverse direction, the pin 11 slides from the second groove 315 to the first groove 314. The pin 11 drives the suction cup body 1 to move backward relative to the mounting base 2. The rear end of the mounting base 2 releases the suction cup body 1 to allow air to enter the adsorption cavity 13.

[0039] like Figure 2 , 6As shown in Figures 7 and 8, in this embodiment, when the pin 11 is located in the first groove 314, the suction cup body 1 is in a state of being ready for installation against the wall or mounting surface, and air is present in the adsorption cavity 13. When the pin 11 is located in the second groove 315, the air in the adsorption cavity 13 is expelled, and under the action of atmospheric pressure and pressure difference, the suction cup body 1 is adsorbed onto the wall or mounting surface. Limiting walls are provided beside both the first groove 314 and the second groove 315 to limit the rotational position of the pin 11.

[0040] After the pin 11 and the connecting seat 12 are first inserted, the pin 11 and the mounting part 31 are then installed. The mounting part 31 is provided with a limiting block 316, which is located outside a first groove 314. The width of the connecting seat 12 is smaller than the minimum diameter of the mounting part 31. In other embodiments, the connecting seat 12 can be passed through the mounting part 31 first, and then the pin 11 can be inserted into the connecting seat 12 until one end of the pin 11 abuts against the limiting block 316 to complete the installation. This is prior art and will not be elaborated further here. In other words, this application provides two installation methods, reducing limitations in production and assembly, and allowing for free selection.

[0041] Optionally, the bottom of the mounting base 2 is provided with an annular rib 23, which abuts against the suction cup body 1; when the knob 3 is rotated in the forward direction and pressed, the annular rib 23 squeezes the suction cup body 1 to expel the air in the suction cavity 13, at which time the bottom of the outer wall of the mounting base 2 abuts against the suction cup body 1.

[0042] like Figure 2 As shown, in this embodiment, the annular rib 23 and the outer wall of the mounting base 2 are spaced apart, and the length of the annular rib 23 in the front-back direction is greater than the length of the outer wall of the mounting base 2.
