A fixing device for a wall hanging

Abstract

This invention discloses a wall-mounted fastening device, including a fixing base, a base shell covering the fixing base, an adhesive component inside the base shell, and a sealing sleeve fitted at the bottom end of the fixing base. The sealing sleeve and the fixing base form a closed adsorption space. This fastening device combines adhesive fastening and adsorption fastening. The adhesive component seals the fixing base and adheres to the wall surface, while simultaneously expelling air from the adsorption space formed by the sealing sleeve and the bottom end of the fixing base. This allows the fixing base to adhere to the wall surface. On the one hand, when the adhesive component is not fully cured and adhered to the wall surface, adsorption fastening isolates air in a negative pressure environment, providing more time for curing. On the other hand, when the adhesive component is fully cured and adhered to the wall surface, the force of the adhesive component can counteract the elastic rebound force of the sealing sleeve, ensuring a longer period of negative pressure adsorption capacity.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment 1

[0024] like Figure 1-3 As shown, a fixing device for a wall hanging comprises a fixing base 1, a base shell 2 is provided on the fixing base 1, an adhesive member 3 for bonding and fixing to the wall base surface is provided in the shell of the base shell 2, the bottom end surface of the adhesive member 3 is coated with a colloid, and the colloid in this embodiment is a liquid or semi-solid glue, and at the same time, a first fitting channel 1-1 is opened on the fixing base 1, the adhesive member 3 is sealed and fitted in the first fitting channel 1-1, and the bottom end surface of the adhesive member 3 extends at least to the fixing At the bottom base surface of the base 1, an adhesive member 3 is passed through the fixed base 1 and bonded to the wall base surface. At the same time, a sealing gasket can be arranged between the adhesive member 3 and the first fitting channel 1-1 to ensure that the adhesive member 3 can be sealed and fitted in the first fitting channel 1-1, and the sealing between the adhesive member 3 and the bottom base surface of the fixed base 1 can also be improved. Then, a second card groove 15 is opened at the bottom end of the outer wall of the fixed base 1, and a sealing rubber sleeve 4 is sleeved at the second card groove 15. The sealing rubber sleeve 4 and the bottom end of the fixed base 1 are sealed. The base surface forms an adsorption space of a suction cup. For this reason, the bottom base surface of the adhesive member 3 cannot exceed the lowest end of the sealing rubber sleeve 4, so that the bottom end of the fixed base can be adsorbed and fixed with the wall base surface through the adsorption space formed by the sealing rubber sleeve 4 and the ground of the fixed base 1 to form a suction cup. The sealing rubber sleeve 4 is composed of a sleeve portion 4-1 and a skirt portion 4-2. The sealing rubber sleeve 4 is sleeved on the second card groove 15 of the fixed base 1 through the sleeve portion 4-1. The skirt portion 4-2 is arranged around the bottom base surface of the fixed base 1. ; This fixing device combines the bonding fixation of the bonding parts 3 and the suction fixation of the suction space formed by the sealing rubber sleeve 4. When the bonding part 3 is pressed down to contact the wall base surface, the air in the suction space is also discharged. Then the suction space formed by the sealing rubber sleeve 4 is adsorbed on the wall base surface, and it also assists the bonding fixation of the bonding part 3 and the wall base surface. The colloid on the bonding part 3 falls off before it dries. The bonding fixation of this fixing device and the suction fixation of the suction cup complement each other, so that the fixing device can be firmly fixed on the wall base surface. Specific embodiment 2

[0026] like Figure 4-6As shown, the difference between this specific embodiment and specific embodiment 1 is that a second interlocking channel 1-2 is opened on the fixed base 1, and an annular groove 5 in which the adhesive member 3 can be embedded is integrally formed in the base shell 2 corresponding to the adhesive member 3, and the annular groove 5 is located in the second interlocking channel 1-2.

The connecting ring 6 is threadedly sleeved on the annular groove 5 integrally formed with the base shell 2, so that the connecting ring 6 performs a lifting movement when the base shell 2 is rotated, thereby achieving the effect of secondary exhausting the adsorption space when the connecting ring 6 rises in the second interlocking channel 1-2, further enhancing the negative pressure adsorption capacity and also improving the load-bearing capacity;

[0027] Specifically, the second interlocking channel 1-2 includes an upper interlocking channel 1-2-1 and a lower interlocking channel 1-2-2, the inner diameter of the upper interlocking channel 1-2-1 is larger than the inner diameter of the lower interlocking channel 1-2-2, and the inner wall of the upper interlocking channel 1-2-1 is a polygonal structure, and the outer wall of the upper end of the connecting ring 6 is integrally provided with a limiting ring 6-1, and the shape of the limiting ring 6-1 matches the upper interlocking channel 1-2-1; the connecting ring 6 is integrally provided with a limiting ring groove 6-2 on the outer wall corresponding to the lower interlocking channel 1-2-2, and the sealing ring 8 is provided with a limiting ring groove 6-2, and the polygonal structure of the limiting ring 6-1 can prevent the connecting ring 6 from rotating when it is lifted or lowered in the second interlocking channel 1-2, and the setting of the limiting ring 6-1 can limit the space for the connecting ring 6 to be lifted or lowered in the second interlocking channel 1-2, thereby avoiding excessive lifting or lowering that affects the adsorption capacity.

[0028] At the same time, the base shell 2 can be rotatably covered on the fixed base 1, and its specific implementation structure is that a first clamping groove 12 is integrally opened at the upper end of the outer wall of the fixed base 1, and a clamping ring 13 is embedded in the upper half of the first clamping groove 12. An "L"-shaped clamping ring 14 is integrally provided on the periphery of the fixed base 1 corresponding to the inside of the base shell 2, and the clamping ring 13 is half-clamped on the clamping ring 14, so that the base shell 2 is covered on the fixed base 1. At the same time, the clamping ring 13 is a corrugated clamping ring, so that the base shell 2 emits a rotation prompt sound when it rotates. Specific embodiment 3

[0030] like Figure 7-8 As shown, this specific embodiment is based on the specific embodiment 2, and a docking groove 9 communicating with the annular groove 5 is opened at the top of the base housing 2 corresponding to the annular groove 5, and a pressing member 10 is embedded in the docking groove 9, and the pressing member 10 is threadedly connected to the end of the adhesive member 3, and a sealing member 11 is provided between the pressing member 10 and the docking groove 9;

[0033] The bottom base surface of the adhesive member 3 may also be provided with a glue groove, which can increase the filling amount of the colloid, as well as the contact area between the colloid and the adhesive member 3 and the wall base surface, thereby enhancing the bonding and fixing ability.

[0034] In addition, in addition to being fixedly installed on a wall base surface, the fixing device can also be fixedly installed on other base surfaces, such as door panels, glass surfaces, other furniture surfaces, etc.
