Description

Technical Field

[0001] The utility model belongs to the field of daily hardware products, in particular to a hook or rack product which is installed on a flat wall and used for hanging objects. Background Art

[0002] Hooks and racks are common tools in life. They can meet the needs of hanging and storing various objects. They are beautiful, can be disassembled and replaced at will, and do not damage the hanging wall. At present, the detachable hooks and racks that are widely used mainly include adhesive type and vacuum adsorption type. The adhesive type uses a fixed frame coated with adhesive as the installation structure; the vacuum adsorption type uses a suction cup component that can be deformed by its own elasticity to generate a close pressure to fix the hanging component to the flat wall. Adhesives cannot be reused, and it is often difficult to maintain a stable fixing force. They are disposable and difficult to clean. The vacuum adsorption type hook racks currently on the market have a relatively complicated structure. Most of them are designed to improve the convenience of adsorption installation operations. Although some of them also have a large initial adsorption force, they are easy to slide after long-term use, and the stability must be improved. At the same time, due to the complex structure and high production cost, it lacks appeal to improve the user's daily use experience and is not conducive to market promotion. Providing a hook rack product with a more scientific structure, simplified structure and improved product fixing force and stability is what the industry pursues. Utility Model Content

[0003] The purpose of the utility model is to provide an enhanced and stable adsorption type suspension frame, which uses a suction cup as a fixing device and is provided with a suction cup cover that is reasonably matched with the suction cup structure, so as to enable the suction cup to form a vacuum adsorption force of appropriate size during use, and keep the suction cup permanently fixed and stable on the installation wall surface, and better meet the user's requirements for product performance and price.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is a suction-type suspension bracket with enhanced stability, comprising a suspension bracket, a suction cup and a knob. The knob has an internal threaded mounting hole. The suspension bracket comprises a suction cup cover and a suspension bracket body, and the suction cup is composed of a threaded mounting shaft connected to a suction piece, and the mounting shaft is matched and connected with the knob mounting hole. The suction cup cover has a shell, a through hole is generated in the middle, and at least three annular support rib structures are evenly and petal-shaped on the inner wall of the shell, and there is a gap between the support ribs. The support ribs are composed of an outer arc and straight edges connected at an angle, and the extension lines of each outer arc form a circular ring with the rotation axis of the shell as the center. The height of the straight edge of the support rib gradually decreases from the outer arc to the angle direction, forming a slope. The suction piece is a circular soft rubber sheet-like piece, in an umbrella shape or a spherical crown shape, and the diameter is between the connecting line of the outer arc of the suction cup cover shell and the support rib. The thickness of the suction piece is 2 mm to 4 mm, and the edge of its bottom surface forms an annular lip with a width of 1 mm to 2 mm.

[0005] The support ribs generated on the inner wall of the suction cup cover can also be composed of an outer arc and an inner arc, that is, a section of arc-shaped ribs replaces two straight edges, the inner arc is connected end to end with the outer arc, the two ends of the inner arc are high, and the middle part is low, forming a slope. The utility model adopts a plurality of support ribs with a slope, which has the following advantages: 1. The support ribs serve as a limit and extrusion structure for the suction piece, which can keep the suction piece fixed to the installation wall: when in use, first loosen the knob, stretch the suction piece on the wall and make its bottom surface fit the wall, and then turn the knob to make the installation shaft drive the middle part of the suction piece to pull upward. Since the suction piece is an elastic soft rubber sheet, after the middle part is pulled, a vacuum cavity is formed between the suction piece and the wall. When the suction piece rises to contact with the support ribs, it stops moving to maintain a vacuum cavity of appropriate size. At the same time, the outer edge of the suction piece is pressed against the wall by the outer arc of the support ribs, forming a circle of fixing force. This structure is different from other vacuum hook products on the market: they either have no limiting structure, the vacuum cavity is infinitely expanded, and it is very easy to damage the seal of the edge; or because there are other structures in the structure as a foil for the suction piece, excessive pressure is formed on the suction piece, and the vacuum cavity cannot be formed, thus affecting the hook to form a lasting adsorption force. The structural characteristics of the suspension rack of the utility model can maintain a vacuum cavity of appropriate size to form an appropriate and balanced air pressure outside the suction piece, so that the product can maintain a large adsorption force and stability, thereby increasing its suspension capacity. At the same time, the annular lip on the edge of the suction piece can be completely fitted with the wall surface to form a more rigorous sealing effect, further enhancing the stability of the suspension rack after installation, and will not slip under the weight of the object. 2. The knob has its own internal thread to cooperate with the installation shaft to adjust the structure of the installation shaft to lift the suction piece, making the installation and disassembly of the suspension rack convenient, which is very suitable for daily use. As mentioned above, tightening the knob will lift the suction piece and generate adsorption force. When you need to disassemble the hanger, loosen the knob, move the installation axis downward, and the suction piece will return to its original state under the action of its own elastic force. Then turn the hanger slightly to remove it from the wall. It can be seen that the operation is very simple and even family women can use it easily. 3. Compared with other vacuum hook products on the market, the product structure is simpler and does not require more adjustment structures. It has more advantages in reducing production and assembly costs, and even use costs, than other hook products.

[0006] Furthermore, in the enhanced and stable adsorption-type suspension frame of the above structure, the outer side of the through hole of the suction cup cover is connected to a cylindrical support, which contacts the threaded hole of the knob to support the knob.

[0007] A base structure is generated on the outside of the suction cup as a support member in contact with the threaded hole of the knob, so that the edge of the knob is separated from the hook frame, which can stabilize the control of the knob when operating the lifting suction piece, and is more conducive to forming a vacuum cavity of appropriate size, making the adsorption of the hook more stable.

[0008] Better yet, in the enhanced and stable adsorption-type suspension frame of the above structure, the suction cup mounting shaft cooperates with the through hole of the suction cup cover to be in the shape of a regular polygonal column.

[0009] The through holes of the mounting shaft and the suction cup are set as regular polygonal columns, so that the mounting shaft is continuously straightened during the lifting process, overcoming the torsional effect of the knob rotation on the suction piece, ensuring that the suction piece is adsorbed and fixed to the wall without moving, which helps to improve the adhesion and stability of the suction piece.

[0010] Preferably, in the enhanced stable adsorption type suspension frame of the above structure, the outer arcs of the supporting ribs of the suction cup cover are connected to form a circular ring structure.

[0011] The outer arcs of the supporting ribs are connected to form a ring, so that the suction piece can be more closely contacted with the wall surface under the pressure of the complete ring, forming a stronger sealing effect and improving the suspension capacity of the suspension frame.

[0012] Optionally, in the enhanced stable adsorption type suspension frame of the above structure, the shape of the suction plate is the same as the shape of the suction cup cover shell, and its annular lip is arranged at the lower end of the shell.

[0013] As mentioned above, the suction piece is the adsorption and fixing structure of the utility model product. The above structural setting makes the product have the following advantages: 1. The lip of the suction piece is used as the part to enhance the seal for stable adsorption. When it is pressed against the wall by the shell of the suction cup cover, the sealing effect of its edge can be further improved and play a role in maintaining stability; 2. After the suction piece is pulled up to form a vacuum cavity in the middle, the pressed and thinner lip of the suction piece can maintain a better sealing effect, which has a significant effect on improving the load-bearing capacity of the suspension frame.

[0014] As another optional structure, in the enhanced stable adsorption type suspension frame of the above structure, the supporting ribs of the suction cup cover are composed of straight edges and connecting ribs located at the outer arc connection position, forming an annular structure supporting the suction plate.

[0015] By changing the closed ring structure of the supporting ribs, arranging the straight edges in a radial or nearly radial pattern, combining them with a regularly changing slope and an outer arc of a higher wall, the suction cup cover provides the same enhanced effect on the support of the suction piece and the limiting effect after adsorption. At the same time, the internal structure of the suction cup cover is simplified, the cost of molds in production is reduced, and consumer needs are better met.

[0016] The utility model discloses an enhanced and stable adsorption type hanging rack, which comprises a hook product with a hook-shaped piece.

[0017] The utility model adopts a specific supporting rib structure on the inner side of the suction cup cover, an enhanced sealing structure on the edge of the suction piece, and a knob assembly with a pulling and releasing function. The combination of the three increases the stability of the suction cup combination structure, making it easier to operate the hanging rack product to complete the adsorption process on the wall. The adsorption capacity is balanced and stable. On the one hand, it can meet the adsorption fixing force and improve the load-bearing capacity. On the other hand, it also has a more superior adsorption stability than other current products. Compared with other existing hook products, the practicality and service life are significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Several preferred embodiments of the present utility model are described below with reference to the accompanying drawings.

[0025] Example 1

[0026] A mop hanging rack, as shown in the figure Figure 1 As shown, it includes a square hanger body A1, a suction piece A2 and a fixed knob A3. The hanger body is composed of a square suction cup frame A10 and a mop clip A11 and a hanging hook A12 connected to the front of the hanger body.

[0027] The structure of the components is shown in the attached Figure 2A square through hole A101 is generated in the middle recessed portion of the inner wall of the square suction cup frame A10. Four supporting rib structures A102 are generated around the recessed portion, symmetrically distributed in a petal shape, with intervals between the structures. The supporting rib structure is composed of an outer arc and two straight edges connected at an angle, and the height of the straight edges gradually decreases from the outer arc to the angle to form a slope. The suction piece A2 is a spherical crown-shaped silicone soft piece with a thickness of 4 mm in the middle and gradually thinning at the edge to form a 2 mm lip piece A20. The center of the suction piece is connected to the installation axis of the square column, and the installation axis extends from the through hole A101 of the suction cup frame A10 to the front of the frame, and its end has a thread. The through hole A101 limits and aligns the installation axis, and adjusts the degree of mobility of the installation axis, so that the size of the vacuum cavity between the suction piece and the installation wall is appropriate during the adsorption operation to maintain a more stable fixing effect.

[0028] The front part of the suction cup frame is connected to the mounting shaft with a fixing knob A3. The inner side of the fixing knob has a threaded hole. By rotating the knob, the suction piece can be pulled forward and backward. Due to the positive effect of the through hole, during the adsorption process, the mounting shaft can only move forward and backward. Even if it is subjected to the torque of the knob in the lateral direction, it will not be twisted. Therefore, the suction piece is locked and stably adsorbed on the wall.

[0029] When this embodiment is used, the hanging bracket is placed against the installation wall surface so that the suction piece fits the smooth surface of the wall surface. At this time, the outer arcs of the supporting ribs press the edge and lip portion A20 of the suction piece. The knob can also be rotated to move the installation shaft backward so that the suction piece fits closely to the wall surface and exhausts the air. The knob is then rotated to move the installation shaft forward, pulling the middle part of the suction piece so that a vacuum chamber is formed between it and the wall surface. The compressed lip portion of the suction piece serves as a sealing structure to keep the vacuum chamber stable. At this time, the outside of the suction piece is subjected to air pressure, and the pressure difference between the inside and outside generates a force that fixes the suction piece and the hanging bracket to the wall surface, so that the hanging bracket remains adsorbed on the wall surface and is used as a mop hanging. When the hanging bracket needs to be disassembled, the knob is loosened, the installation shaft moves backward, and the suction piece returns to its initial state under the action of its own elastic force. Then the hanging bracket is gently turned to be detached from the wall surface.

[0030] Example 2

[0031] A suction type vacuum hook, as attached Figure 3 As shown, it includes a circular hanger body B1 with a hook, a suction piece B2 and a fixing knob B3.

[0032] The structure of the components is shown in the attached Figure 4, five supporting rib structures B102 are generated on the inner wall of the circular bracket body B1, which are evenly distributed in the shape of petals, and there are intervals between each structure. The supporting rib structure is composed of an outer arc and two straight edges connected at an angle. The height of the straight edges gradually decreases from the outer arc to the angle, forming a slope. A square through hole B101 is generated in the middle of the inner wall of the circular bracket body B1, and a square cylindrical support B103 is generated on the outer side of the bracket body. The suction sheet B2 is a spherical crown-shaped silicone soft sheet with a larger thickness in the middle and gradually thinning at the edges to form a lip-shaped sheet. The center of the suction sheet B2 is connected to a square columnar mounting shaft B20, which extends from the through hole of the bracket body B1 to its front, and the end of the mounting shaft has a threaded structure.

[0033] The front part of the bracket body is connected to the mounting shaft B20 with a fixed knob B3, and the inner side of the fixed knob has a threaded hole, and the suction piece can be pulled forward and backward by rotating the knob. The threaded hole part of the fixed knob contacts the cylindrical support B103 of the bracket body, and the support supports the knob so that it has a certain gap with the bracket body, which is convenient for rotation operation.

[0034] In this embodiment, the hanger together with the suction piece is placed against a smooth wall surface, and the suction piece can be tightly attached to the wall surface by pressure or rotating the knob, and then the knob is rotated to move the middle part of the suction piece forward to form a vacuum cavity, and the atmospheric pressure difference between the inside and outside of the suction piece generates adsorption force, and the hook product is fixed on the wall surface, which acts as a hanging tool. The operation and effect are basically the same as those of embodiment 1.

[0035] Example 3

[0036] A mop hanging bracket clip product, such as the attached Figure 5 As shown, it includes a square hanger body C1, a suction piece C2 and a fixed knob C3. The hanger body is composed of a square suction cup frame C10 and a mop clip C11 and a hanging hook C12 connected to the front of the hanger body.

[0037] The structure of the components is shown in the attached Figure 6 , and Example 1, in this embodiment, a through hole C101 is also formed in the middle recessed portion of the inner wall of the square suction cup frame C10, and a ring-shaped supporting rib plate structure C102 is formed around the recessed portion. The supporting rib plate structure C102 is composed of four rib walls C1020 with inward right-angle turns and an outer arc C1021 connecting each right-angle turn. The height of each rib wall C1020 gradually decreases from the outer arc to the angle direction, forming a slope, which supports and limits the suction piece C2.

[0038] The suction sheet C2 is a spherical cap-shaped silicone soft sheet, and its shape and structure are the same as those of Example 1. The other structures and operation methods of this embodiment are also the same as those of Example 1, and please refer to the description of Example 1.

[0039] The above describes several preferred embodiments of the present invention with reference to the accompanying drawings, but does not mean that it is limited to the structure of the embodiments. All modifications, equivalent substitutions and additions within the technical scope of the claims of the present invention, such as increasing the size of the suction piece to the same shape as the outer shell of the product hanging frame / suction cup cover, setting the straight edge of the supporting rib structure in an arc shape, and other similar structural changes, of course, also belong to the technical scope of the present invention.
