Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities hooks, and particularly refers to a wall-mounted bracket for widely adjusting the bottle mouth size. Background Art

[0002] Currently, there is a type of bracket for hanging a packaging bottle containing washing supplies on the wall and adjusting the size of the bottle mouth. The bracket is provided with a slider that can be moved back and forth for adjustment. The lock cap with a pressing pump is unscrewed to remove the pressing pump. The bottle mouth of the packaging bottle is sleeved into the bracket from bottom to top, and then the pressing pump is reinstalled into the packaging bottle. The slider moves forward to clamp the bottle mouth, and the lock cap is screwed tightly. The lock cap tightly presses against the bracket support and the adjusting slider to complete the installation. The adjustment range of the bottle mouth size of the existing bracket structure is limited. Usually, for the washing supplies bought, the bottle mouth of the packaging bottle often cannot be installed on the bracket, either being too large or too small. The reason for this embarrassing situation is that there are many different specifications of bottle mouth sizes, commonly used ones are different specifications from 20 teeth to 50 teeth (international or national standard teeth). The washing supplies manufacturers design the pressing pump according to the maximum amount of liquid pumped out by the pressing pump at one time, the production and filling speed of the packaging bottle, the amount of foam generated, etc. The pressing pump matches the bottle mouth of the packaging bottle, and then designs the bottle mouth size of the packaging bottle. The most commonly used bottle mouth tooth types for shower gel, shampoo, and dishwashing liquid are 33 teeth, 30 teeth, and 28 teeth. The foaming pump for hand sanitizer or shower gel generates relatively large and virtual foam, and the size of the foaming chamber must be made larger, so the bottle mouth size has to be made larger accordingly. Commonly seen ones are also from 35 teeth to 50 teeth. Currently, the existing adjustable bottle mouth size brackets in the prior art cannot adapt to such a large range of changes in tooth sizes. In addition, for the existing adjustable brackets, the adjusting slider moves back and forth in the slot according to the bottle mouth size for adjustment. The adjusting slider is not fixed, and the washing supplies bottle is prone to slipping out of the bracket and falling during pressing. The existing plastic bracket structure is prone to breakage due to insufficient strength. These defects are confirmed from the feedback of online sales. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a wall-mounted bracket for widely adjusting the bottle mouth size, and make improvements in fixing the adjusting block and further strengthening the strength of the bracket. This application focuses on technical improvements in these three aspects.

[0004] The following directions such as up and down, left and right, front and back refer to the directions when the bracket is hung on the wall.

[0005] Improvement in the adjustment range of the bottle mouth size of the bracket: The packaging materials of bottled or bagged washing products are hung on the support of the bracket with adjustable size. The size of the bottle mouth is adjusted by moving the slider back and forth. The farther the center distance (the center distance refers to the distance from the center of the bottle inlet of the bracket to the back of the bracket), the longer the lever arm (the lever arm refers to the distance from the center of gravity of the hanging part to the front of the bracket), and the greater the bending moment borne by the bracket. This is an unfavorable factor for the bracket to break due to long-term hanging of heavy objects. For the same hanging weight, the bending moment and the lever arm are in a positive linear correlation. Therefore, the lever arm should be shortened as much as possible (that is, the center distance should be shortened) to reduce the bending moment. However, when the center distance is shortened, larger bottles cannot be hung. And to accommodate larger bottles, for bottles with an elliptical or rectangular cross-section, hanging the short axis diameter or width direction in the front-back direction and the long axis diameter or length direction in the left-right direction can reduce the center distance. From the existing production of packaging bottles, a center distance of 60 mm, that is, a short axis diameter of 60 mm, can meet the hanging space of most packaging bottles; when the center distance increases, the adjustment range can also increase, but the bending moment also increases, and the strength of the bracket must be strengthened, otherwise the weak parts of the bracket are prone to break during use. Usually, the stress is concentrated at the corner of the front of the bracket and the support, and this part needs to be strengthened more.

[0006] The adjusting block stops at the front of the bracket. Although a relatively long adjustment distance can be obtained, it is not the longest adjustment distance. Through optimization in this application, the longest adjustment distance can be obtained under the condition of determining the center distance, that is, a through hole is further extended from the front of the bracket to the back of the bracket, and the adjusting block penetrates into the through hole and reaches the back of the bracket. If only one adjusting block is used for large-range adjustment, the center distance must be increased, and the bending moment borne by the bracket also becomes larger, making the bracket bulky and occupying a large space. If both reducing the bending moment and occupying less space are taken into account, multiple adjusting blocks can be selected for multi-stage adjustment. For example, for the commonly used bottle mouths from 50 teeth to 20 teeth, it is preferred to use two adjusting blocks for two-stage adjustment. The first-stage adjustment short block adjusts from 50 teeth to 35 teeth, and the second-stage adjustment long block adjusts from 33 teeth to 20 teeth. The second stage starts from 33 teeth because the tooth profile from 33 teeth to 28 teeth is the most commonly used bottle mouth tooth profile in households. Compared with the adjusting short block, the adjusting long block in the second stage reduces the arc degree of the bearing surface, and the area of the bearing surface of the adjusting block can be increased. The area of the bearing surface of other tooth profiles below 33 teeth also increases accordingly. The bearing surface of the adjusting block at the front end of the adjusting block and the bearing surface of the support are in the same plane. In this way, almost all commonly used packaging bottle tooth sizes are covered, eliminating the trouble that the packaging bottle cannot be installed on the bracket after buying washing products. The material of the adjusting block can be either plastic or metal to increase its strength. Of course, the upper limit of the bottle mouth size of the present invention is not limited to 50 teeth only, and it can also be used for adult shower gel foam pumps with more than 50 teeth or those that have not yet been popularized with 60 teeth.

[0007] The adjusting block fixing device is composed of a nut seat, a through hole, an adjusting nut and an adjusting screw that mates with it. Usually, the adjusting screw is used on the upper part and the adjusting nut is used on the lower part. It is also possible to use the adjusting nut on the upper part and the adjusting screw on the lower part. A moving groove that mates with the nut seat and an adjusting hole for the adjusting block to move back and forth to avoid the adjusting screw are provided on the adjusting block. A through hole that penetrates the nut seat vertically and allows the adjusting screw to pass through is provided on the nut seat. The front of the support and the corner of the support are already stress-concentrated. Opening a through-hole further weakens the strength of the support. The hole wall extending to the back of the support can strengthen the weakened strength of the support. The adjusting block can move freely back and forth in the through-hole to achieve stepless adjustment. The adjusting screw passes through the through hole. Tighten the adjusting screw to fix the adjusting block to the nut seat, preventing the adjusting block from retracting backward when pressing the pressure pump and causing the packaging bottle to slide out of the support from the bearing surface and fall.

[0008] A storage groove is opened above the through-hole entrance, and the hole wall extends to the front end of the storage groove. It has two purposes. One of the two adjusting blocks that are not in use is placed on the storage groove. If it is stored elsewhere, there may be an embarrassing situation where it cannot be found when needed. In addition, since the through-hole is opened, the hole wall extending to the front end of the storage groove can also strengthen the strength of the through-hole entrance.

[0009] A bottle inlet is opened on the support, a bearing surface is opened around the bottle inlet, and strengthening ribs for increasing the strength of the support are opened around the periphery of the bearing surface on the left and right sides of the front of the support to increase the strength of the support. In the embodiment, an inverted U-shaped cross-section is opened. Of course, it can also be a regular U-shaped cross-section. As the hanging weight increases, inverted double U-shaped cross-sections, regular double U-shaped cross-sections and other structures can also be used to further strengthen the strength of the support.

[0010] Criss-crossing strengthening ribs are opened on the back of the support, under the support and inside the strengthening ribs so that the strength of the support can be increased without increasing the wall thickness of the support.

[0011] To solve the technical problems to be solved by the present invention, the present invention adopts the following technical solutions: A wall-mounted support for widely adjusting the bottle mouth size, including a support and a support fixing device. The support includes a support seat, a bearing surface, a bottle inlet, the front of the support, the back of the support, a storage groove and a bottom surface. A vertically penetrating bottle inlet is opened on the support seat, a bearing surface is opened around the bottle inlet, a storage groove is opened on the upper part of the support seat and extends forward from the front of the support, at least including an adjusting block for adjusting the bottle mouth size and an adjusting block fixing device, and also including a through-hole. A through-hole is opened on the upper surface of the support seat, extends from below the storage groove to the back of the support and allows the adjusting block to move freely back and forth.

[0012] Preferably, the hole wall of the through-hole extends from the front of the support to the front end of the storage groove and from the bottom surface to the back of the support.

[0013] Preferably, reinforcing ribs for increasing the strength of the bracket are formed around the periphery of the bearing surface starting from the left and right sides of the front surface of the bracket.

[0014] Preferably, the adjusting block includes an adjusting long block and an adjusting short block. The front end of the adjusting block is provided with an adjusting block bearing surface that is in the same plane as the bearing surface on the support. An adjusting hole is formed in the adjusting block for the adjusting block to move back and forth to avoid the adjusting screw, and a moving groove is formed on the back surface of the adjusting block for the adjusting block to move freely on the nut seat.

[0015] Preferably, the adjusting block fixing device includes an adjusting screw and an adjusting nut. A nut seat is formed on the support, and a through hole for the adjusting screw to pass through is formed in the nut seat. A nut groove for placing and tightly fitting the adjusting nut is formed on the bottom surface of the nut seat, and the depth of the nut groove is equivalent to the thickness of the adjusting nut.

[0016] Preferably, reinforcing ribs for increasing the strength of the bracket are formed vertically and horizontally in the back surface of the bracket, the bottom surface of the support and the reinforcing ribs.

[0017] Preferably, the bracket fixing device includes a suction sticker, a force transmission hole, a force transmission pin, a support tube, a pin hole and a seat groove; a seat groove is formed in the back surface of the upper part of the bracket, at least one group of horizontally penetrating force transmission holes are formed in the upper part of the bracket, a support tube is formed on the suction sticker, the support tube is embedded in the seat groove above the bracket, the force transmission pin is sleeved in the force transmission hole and the pin hole, and the force transmission pin is inserted into the force transmission hole from one end, passes through the pin hole, and is inserted out from the other end of the force transmission hole, so as to fix the bracket on the suction sticker.

[0019] In summary, the structure of the present invention is simple, the adjustment range of the adjusting block is large, almost covering most of the existing outer diameter sizes of the bottle necks of packaging bottles, eliminating the trouble that the packaging bottles for containing washing products cannot be assembled on the bracket, and eliminating the risk that the packaging bottles slide out of the bracket and fall to the ground during the pressing process of the pressing pump; at the same time, the strength around the bearing surface of the support is strengthened, and there is no need to worry about the bracket breaking caused by long-term hanging of heavy objects or being pressed during transportation.
