Description

Technical Field

[0001] This utility model belongs to the field of auxiliary devices for press bottles, and specifically relates to a fastening component for press bottles. Background Technology

[0002] Currently, daily chemical products are appearing more and more frequently in people's lives. Washing and care products have become deeply integrated into people's lives, making it convenient for people to use them for cleaning and washing their belongings and bodies. These daily chemical products are generally stored in the form of pump bottles. When needed, a fixed amount of daily chemical product can be dispensed by pressing the pump head at the top of the bottle. While these products are very convenient to use, they also take up a lot of space. In today's homes where every inch of space is precious, when these daily chemical products are neatly placed in the kitchen and bathroom, the space will appear bloated and take up too much space. In addition, it is inconvenient to use them promptly, and there is rarely a dedicated place to store them. Therefore, fixing the pump bottle to the wall can make it convenient to use. However, when the pump bottle is fixed to the wall, it is more cumbersome to replace the daily chemical product after use. If the storage bottle is designed with a detachable structure, it is easier to open the cap for replacement. However, the ease of opening the cap also means that it is easy for outsiders to disassemble, which may pose a certain safety hazard to children. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a fastening component for a press-type bottle. By setting a first protrusion and a second protrusion on the upper and lower parts of the split storage bottle, which can be aligned during twisting, a complete limiting post is formed after they are joined together. The limiting post is embedded in the slot hole. Firstly, it can prevent the vertical axial displacement of the upper and lower parts of the bottle after twisting is completed. Secondly, it can limit the twisting of the upper part of the bottle in the circumferential direction, thereby ensuring that the storage bottle embedded in the slot hole can be well fixed, and it can also be easily removed during the removal of the storage bottle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fastening assembly for a press-type bottle includes a housing bottle, a fixing frame, and a mounting plate. The housing bottle is detachably connected to an upper bottle and a lower bottle. The inner side of the bottom of the upper bottle has an abutment post, and the outer side of the upper end of the lower bottle has a 7-shaped limiting portion. The upper end of the limiting portion is horizontally oriented, and the lower end of the limiting portion is vertically downward and connected to the lower bottle. The upper end face of the abutment post can abut against the lower end face of the upper end. The upper bottle has a first protrusion, and the lower bottle has a second protrusion. After the upper and lower bottles are connected, the first and second protrusions abut against each other and align to form a limiting post. The limiting post is fitted into a slot on the fixing frame. The connection between the upper and lower bottles restricts axial displacement between them, and the connection between the limiting post and the slot restricts the circumferential movement of the first and second protrusions. The outer side of the lower bottle has a liquid level inspection elongated hole penetrating the inner cavity.

[0006] The slot on the fixing frame has an opening at the top and side. The slot is trapezoidal on the upper surface of the fixing frame. The cross-section of the limiting post is a trapezoidal structure with a wide outer end and a small contact surface with the bottle. The limiting post is embedded in the slot from top to bottom.

[0007] The mounting plate is detachably connected to the fixing frame. The mounting plate is provided with a limiting piece, which is inclined downwards and toward the slot on the side of the fixing frame. The end of the limiting piece abuts against the upper end face of the first protrusion. The second protrusion is provided with a buffer groove, which is abuttingly connected to the limiting piece. The lower end face of the second protrusion is provided with an upwardly inclined buffer part. The mounting plate is provided with mounting holes for mounting on the wall.

[0008] The fastening assembly of the press-type bottle with this structure consists of an upper bottle and a lower bottle screwed together. An inner bottle is inserted into the lower bottle, and the upper bottle is fitted onto the inner bottle. Daily chemical products are placed inside the inner bottle. Therefore, the combination of the upper and lower bottles can effectively protect the inner bottle, ensuring that the daily chemical products inside are double-isolated, and also allowing for quick replacement of the inner bottle. In addition, the outer side of the lower bottle has a liquid level inspection hole that penetrates the inner cavity. After the inner bottle is inserted into the lower bottle, when the daily chemical products inside are almost used up, the liquid level can be observed in time through the liquid level inspection hole to determine when the inner bottle needs to be replaced.

[0009] With the engagement of the abutment post and the limiting part, the upper bottle and the lower bottle are tightly connected in the axial direction, making it impossible to separate them axially. They can only be separated axially by misalignment during the circumferential twisting motion of the upper bottle. When the upper bottle and the lower bottle are screwed together, the first protrusion on the upper bottle and the second protrusion on the lower bottle abut and align to form a continuous limiting post. After the limiting post is inserted into the slot on the fixing frame, the first protrusion cannot be freed from the constraint of the slot during circumferential twisting. Therefore, the circumferential movement of the first and second protrusions can be restricted, making it impossible to open the upper bottle after the bottle is inserted into the slot.

[0010] The upper end face of the slot is designed as a trapezoid, and the cross-section of the limiting post is also trapezoidal. Therefore, during the process of the limiting post being inserted into the slot, the smaller contact area between the limiting post and the bottle can be held in place by the slot, thus preventing the limiting post from detaching radially from the slot and achieving a more secure connection. To ensure that after the limiting post is inserted into the slot from top to bottom, the bottle is lifted upwards for positioning, preventing the bottle from detaching from the slot when pushed upwards, a limiting plate is provided on the mounting plate. The limiting plate is inclined downwards. The limit post extends into the projection surface of the trapezoidal structure on the upper end face of the slot. Therefore, during the process of the limit post being inserted into the slot from top to bottom, the buffer part provided on the lower end face of the second protrusion will first abut against the limit piece, causing the limit piece to deform. The end of the limit piece moves upward along the outer end face of the second protrusion until it is embedded in the buffer groove on the second protrusion, achieving initial fitting and fixation. Then, the bottle is pressed down further. At this time, the limit piece is released from the constraint of the buffer groove and continues to move upward until it abuts against the upper end face of the first protrusion, thus achieving the restriction of the up and down movement of the bottle.

[0011] Furthermore, it also includes an ejector, the upper end face of the fixing frame is provided with an ejector hole facing the limiting piece, the ejector is fitted into the ejector hole and is abuttingly connected to the upper end face of the limiting piece; the ejector is provided with a tube column, the tube column abutting against the side of the fixing frame; the tube column includes two sets, the two sets of tube columns are arranged opposite each other with the ejector as the center of symmetry, and the two sets of tube columns abut against the two end sides of the fixing frame respectively.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the screwing of the upper and lower bottles achieves a tight connection in the axial direction. It can only be separated axially by misalignment during the circumferential twisting of the upper bottle. When the upper and lower bottles are screwed together, the first and second protrusions abut and align to form a continuous limiting post. After the limiting post is inserted into the slot on the fixing frame, the first protrusion cannot be freed from the constraint of the slot during circumferential twisting. With the assistance of the limiting plate, the up and down movement of the limiting post in the slot can be restricted. Therefore, when it is necessary to replace the daily chemical products in the storage bottle, press down on the limiting plate, lift up the storage bottle to get it free from the constraint of the slot, and then twist the upper bottle to open the storage bottle for replacement.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0023] like Figure 1-6 As shown, a fastening assembly for a press-type bottle includes a container bottle 1, a fixing frame 2, and a mounting plate 3. The container bottle 1 is detachably connected to an upper bottle 11 and a lower bottle 12. An abutment post 112 is provided on the inner side of the bottom of the upper bottle 11. A 7-shaped limiting part 122 is provided on the outer side of the upper end of the lower bottle 12. The upper end of the limiting part 122 is horizontally oriented, and the lower end of the limiting part 122 is vertically downward and connected to the lower bottle 12. The upper end face of the abutment post 112 can abut against the lower end face of the upper end. A first protrusion 111 is provided on the upper bottle 11. The lower bottle 12 is provided with a second protrusion 121. After the upper bottle 11 and the lower bottle 12 are connected, the first protrusion 111 and the second protrusion 121 abut against each other and form a limiting post 13. The limiting post 13 is connected to the slot 21 on the fixing frame 2. The connection between the upper bottle 11 and the lower bottle 12 restricts the axial displacement between the upper bottle 11 and the lower bottle 12. The connection between the limiting post 13 and the slot 21 restricts the circumferential movement of the first protrusion 111 and the second protrusion 121. The outer side of the lower bottle 12 is provided with a liquid level inspection elongated hole that penetrates the inner cavity.

[0024] The slot 21 on the fixing frame 2 has an opening at the top and side. The slot 21 has a trapezoidal structure on the upper surface of the fixing frame 2. The cross-section of the limiting post 13 is a trapezoidal structure with a wide outer end face and a small contact surface with the container bottle 1. The limiting post 13 is embedded in the slot 21 from top to bottom.

[0025] The mounting plate 3 is detachably connected to the fixing frame 2. The mounting plate 3 is provided with a limiting piece 31, which is inclined downward and toward the slot 21 on the side of the fixing frame 2. The end of the limiting piece 31 abuts against the upper end surface of the first protrusion 111. The second protrusion 121 is provided with a buffer groove 123, which is abuttingly connected to the limiting piece 31. The lower end surface of the second protrusion 121 is provided with an upwardly inclined buffer part 124. The mounting plate 3 is provided with mounting holes 32 for mounting on the wall.

[0026] Furthermore, it also includes an ejector 4. The upper end face of the fixing frame 2 is provided with an ejector hole 22 facing the limiting piece 31. The ejector 4 is fitted into the ejector hole 22 and is in contact with the upper end face of the limiting piece 31. The ejector 4 is provided with a tube column 41, which abuts against the side of the fixing frame 2. The tube column 41 includes two sets, which are arranged opposite each other with the ejector 4 as the center of symmetry. The two sets of tube columns 41 abut against the two end sides of the fixing frame 2 respectively.

[0027] Description of the working principle of this utility model:

[0028] The fastening assembly of the press bottle with this structure is formed by screwing together an upper bottle 11 and a lower bottle 12. An inner bottle is inserted into the lower bottle 12, and the upper bottle 11 is fitted onto the inner bottle. Daily chemical products are placed inside the inner bottle. Therefore, the storage bottle 1 formed by the upper bottle 11 and the lower bottle 12 can effectively protect the inner bottle inside, ensuring that the daily chemical products inside are double-layered and can also be quickly replaced. In addition, the outer side of the lower bottle 12 is provided with a liquid level inspection hole that penetrates the inner cavity. After the inner bottle is inserted into the lower bottle 12, when the daily chemical products inside are almost used up, they can be observed in time through the liquid level inspection hole to know when the inner bottle needs to be replaced.

[0029] With the engagement of the abutment post 112 and the limiting part 122, the upper bottle 11 and the lower bottle 12 are tightly connected in the axial direction, making it impossible to separate the upper bottle 11 and the lower bottle 12 in the axial direction. They can only be separated in the axial direction by misalignment during the circumferential twisting motion of the upper bottle 11. When the upper bottle 11 and the lower bottle 12 are engaged, the first protrusion 111 on the upper bottle 11 and the second protrusion 121 on the lower bottle 12 abut and align to form a continuous limiting post 13. After the limiting post 13 is inserted into the slot 21 on the fixing frame 2, the first protrusion 111 cannot be freed from the constraint of the slot 21 during the circumferential twisting process. Therefore, the circumferential movement of the first protrusion 111 and the second protrusion 121 can be restricted, so that the upper bottle 11 cannot be opened after the container bottle 1 is inserted into the slot 21.

[0030] The upper end face of the slot 21 is designed as a trapezoid, and the cross-section of the limiting post 13 is also trapezoidal. Therefore, during the process of the limiting post 13 being inserted into the slot 21, the smaller contact area between the limiting post 13 and the container bottle 1 can be held in place by the slot 21, thus preventing the limiting post 13 from detaching radially from the slot 21 and achieving a more secure connection. In order to limit the container bottle 1 by lifting it upward after the limiting post 13 is inserted into the slot 21 from top to bottom, and to prevent the container bottle 1 from detaching from the slot 21 when it is pushed up from bottom to top, a limiting piece 31 is provided on the mounting plate 3. The limiting piece 31 is inclined downward and extends into the slot. Within the projection plane of the trapezoidal structure on the upper end face of the hole 21, during the process of the limiting post 13 being inserted into the slot 21 from top to bottom, the buffer part 124 provided on the lower end face of the second protrusion 121 will first abut against the limiting piece 31, causing the limiting piece 31 to deform. The end of the limiting piece 31 moves upward along the outer end face of the second protrusion 121 until it is embedded in the buffer groove 123 on the second protrusion 121, achieving initial fitting and fixation. Then, the bottle 1 is pressed down further, at which point the limiting piece 31 is released from the constraint of the buffer groove 123 and continues to move upward until it abuts against the upper end face of the first protrusion 111, thus achieving the restriction of the up and down movement of the bottle 1.

[0031] To release the limiting effect of the limiting piece 31, the limiting piece 31 needs to be pressed to disengage from the projection surface of the trapezoidal structure on the upper end face of the slot 21 before the limiting post 13 can be released from the slot 21. However, manual pressing is difficult, so an ejector 4 is added. At the same time, an ejector hole 22 facing the limiting piece 31 is provided on the upper end face of the fixing frame 2. After inserting the ejector 4 from top to bottom into the ejector hole 22 and abutting against the limiting piece 31, the limiting piece 31 is pushed down forcefully, causing the limiting piece 31 to deform. Freed from the restriction of the limiting piece 31, the bottle 1 can be quickly pulled out. Since the ejector 4 is inserted into the ejector hole 22 for backup without pushing down the limiting piece 31, the ejector 4 is easy to loosen and fall off. Therefore, a tube post 41 is added to both ends of the ejector 4. The tube post 41 abuts against the two ends of the fixing frame 2, making the entire ejector 4 have a fork-shaped structure. Therefore, the ejector 4 can be inserted into the fixing frame 2 without downward force. Moreover, this ejector 4 is a special item and can only be used on this model.

[0032] When installing the fastening assembly, first, the mounting plate 3 is abutted against the wall. After fixing the mounting plate 3 to the wall by screwing screws into the mounting hole 32, the rear opening of the fixing bracket 2 is pressed and abutted against the outer contour of the mounting plate 3. During the installation of the fixing bracket 2, the limiting piece 31 on the mounting plate 3 extends into the projection surface of the trapezoidal structure on the upper end face of the slot hole 21. After the daily chemical products are placed into the lower bottle 12, the upper bottle 11 is screwed onto the lower bottle 12. The first protrusion 111 and the second protrusion 121 are aligned and form a limiting post 13. The limiting post 13 is inserted into the slot hole 21 from top to bottom until the limiting piece 31 abuts against the upper end face of the first protrusion 111. When disassembly is required, the ejector 4 in the ejection hole 22 is pushed downwards to forcefully push the limiting plate, and the bottle 1 can be pulled out.

[0033] The beneficial effects of this utility model are as follows: by screwing the upper bottle 11 and the lower bottle 12 together, a tight connection is achieved in the axial direction. The bottles can only be separated axially by misalignment during the circumferential twisting motion of the upper bottle 11. When the upper bottle 11 and the lower bottle 12 are screwed together, the first protrusion 111 and the second protrusion 121 abut and align to form a continuous limiting post 13. After the limiting post 13 is inserted into the slot 21 on the fixing frame 2, the first protrusion 111 cannot be freed from the constraint of the slot 21 during the circumferential twisting process. With the assistance of the limiting piece 31, the up and down movement of the limiting post 13 in the slot 21 can be restricted. Therefore, when it is necessary to replace the daily chemical products in the storage bottle 1, the limiting piece 31 is pushed down by the ejector 4, the storage bottle 1 is lifted to get free from the constraint of the slot 21, and the upper bottle 11 is twisted to open the storage bottle 1 for replacement.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
