Description

Technical Field

[0001] This utility model relates to the field of wall-mounted hook and loop fastener technology, and more specifically, to a wall-mounted hook and loop fastener. Background Technology

[0002] In the field of wall-mounted hook and loop fasteners, the reliability of the fixing method, the convenience of the air extraction operation, and the stability of the sealing structure are key factors affecting the performance. However, wall-mounted hook and loop fasteners on the market still have many technical defects in practical applications. These problems not only affect the performance of the product, but may also reduce its service life and installation reliability.

[0003] The primary problem is the significant lack of reliability in the fixing methods. Existing fixing methods have significant defects: First, when using glue, not only are difficult-to-remove residues left on the wall, but the fixing strength may also decrease due to glue aging; second, the adhesive force of the glue changes with changes in ambient temperature and humidity, affecting the fixing effect; third, although fixing with nails is secure, it can cause permanent damage to the wall surface, affecting its aesthetics. These shortcomings of traditional fixing methods not only reduce the practicality of the product, but may also cause the main tape to fall off due to unstable fixing, failing to meet the needs of long-term use.

[0004] More notably, the ease of operation of the suction cup is severely lacking. Existing suction cup structures have significant operational problems: First, the suction cup uses a simple nut-sealed design, lacking a scientific operating mechanism; second, repeated operation is required to achieve the desired negative pressure effect during the suction process, increasing installation time; third, the simple nut-sealed structure is not only cumbersome to operate, but may also cause the negative pressure effect to gradually weaken due to poor sealing. These shortcomings of traditional suction methods not only affect installation efficiency, but may also lead to poor fixation due to improper operation, reducing the user experience of the product.

[0005] Most critically, the sealing structure is severely unstable. Although some devices have achieved negative pressure maintenance by adding a one-way sealing mechanism, this design still has obvious defects: First, the simple spring-driven mechanism lacks reliable sealing protection; second, during the reset process after the air extraction is completed, outside air can easily seep into the suction cup through the gaps in the sealing structure; third, the single thrust of the spring is difficult to cope with pressure changes under different operating environments. This structural design deficiency not only affects the durability of the adsorption effect, but may also cause the suction cup to fall off due to seal failure, reducing the reliability of the product.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a wall-mounted hook and loop fastener, which has the following advantages:

[0019] 1. The bonding device constructs a reliable fixing system through the reasonable combination of the fixing chamber and suction cups. The fixing chamber provides a stable installation base for the mother tape, and the design of multiple suction cups increases the contact area with the wall. Negative pressure adsorption achieves non-destructive fixing. This design not only avoids the problem of residual glue caused by traditional glue fixing and the damage to the wall caused by nail fixing, but also ensures the durability of the fixing effect through scientific negative pressure adsorption, effectively solving the problem of unreliability of traditional fixing methods.

[0020] 2. The one-way device constructs a highly efficient one-way system through the precise cooperation of components such as the fixed pipe, connecting pipe, and one-way plate. The design of the air inlet groove, connecting groove, and central through groove on the fixed rod forms a scientific airflow channel. The concave structure of the one-way plate achieves excellent airflow guidance. The cooperation between the push spring and the fixed plate enables the precise use of the one-way plate. The setting of multiple air inlet grooves and connecting grooves not only improves the pumping efficiency, but also ensures smooth airflow through the connecting design of the central through groove, effectively solving the problem of cumbersome traditional pumping operation.

[0021] 3. The protective mechanism, through the ingenious cooperation of the control sleeve, screw sleeve, and screw rod, constructs a reliable protective locking system. The meshing transmission of the internal and external gears provides a synchronous control basis for the overall structure. The setting of multiple screw sleeves and screw rods ensures uniform force on the one-way plate. The design of the connecting sleeve realizes the synchronous movement of the screw rod. This structure not only provides precise control through threaded transmission to achieve active locking and sealing, but also prevents deformation of the sealing structure through a multi-point synchronization mechanism, effectively solving the problem of instability in traditional sealing structures.

[0031] Please see Figures 1-5A wall-mounted hook and loop fastener includes a main strap 1. An adhesive device is installed on one side of the main strap 1. The adhesive device includes a fixing chamber 2 and a suction cup 3. The main strap 1 is installed on one side of the fixing chamber 2, and the suction cup 3 is also installed on one side of the fixing chamber 2. A one-way device is installed on one side of the fixing chamber 2. The one-way device includes a fixing tube 4, a connecting tube 5, a one-way plate 6, an air inlet groove 7, a push spring 8, an air outlet groove 9, a connecting groove 10, a central groove 11, a fixing plate 12, and a fixing rod 13. The fixing tube 4 is fixedly installed on one side of the fixing chamber 2. The one-way plate 6 is slidably sleeved on the outside of the fixing rod 13. The air inlet groove 7 is formed on the side wall of the fixing rod 13. The two ends of the push spring 8 are respectively connected to the one-way plate 6 and the fixing plate 12. The air outlet groove 9... A connecting groove 10 is formed at one end of the connecting pipe 5, a connecting groove 10 is formed on the side wall of the fixing rod 13, a through groove 11 is formed inside the fixing rod 13, a fixing plate 12 is fixedly set inside the fixing pipe 4, and the fixing rod 13 is fixedly installed inside the connecting pipe 5. A protective mechanism is provided inside the fixing pipe 4. The protective mechanism includes a control sleeve 14, a screw sleeve 15, a screw 16, an internal gear 17, and an external gear 18. The two ends of the control sleeve 14 are rotatably connected to the connecting pipe 5 and the fixing pipe 4, respectively. The screw sleeve 15 is rotatably installed on the fixing plate 12. The screw 16 is movably installed inside the screw sleeve 15 through a thread. The internal gear 17 is fixedly installed inside the control sleeve 14, and the external gear 18 meshes with the internal gear 17.

[0032] A sub-belt 19 is detachably provided on one side of the mother belt 1.

[0033] There are multiple suction cups 3.

[0034] In this embodiment, when the device is to be used, first ensure that the wall is smooth and clean, then fix the main tape 1 to one side of the fixing chamber 2, then attach multiple suction cups 3 to the wall, then connect the external air pump to the connecting pipe 5, then draw the pressure inside the fixing chamber 2 and the suction cups 3 to a negative pressure state, so that the suction cups 3 are firmly attached to the wall, then seal the fixing pipe 4 and the connecting pipe 5, then remove the external air pump, and then attach the sub-tape 19 to one side of the main tape 1.

[0035] Please see Figures 3-5 As a further implementation of the overall equipment: multiple air inlet slots 7, connecting slots 10 and air outlet slots 9 are provided.

[0036] The air intake slot 7 and the connecting slot 10 are connected by the central through slot 11.

[0037] One side of the one-way panel 6 has a concave structure design.

[0038] Multiple external gears 18, threaded sleeves 15, and screws 16 are provided, and the external gears 18 are fixedly installed on the outside of the threaded sleeves 15.

[0039] A connecting sleeve 20 is movably provided on one side of the fixing plate 12, and the connecting sleeve 20 is fixedly connected to multiple screws 16.

[0040] More specifically, when a vacuuming operation is required, first, the input end of the vacuum pump is securely connected to the connecting pipe 5. Then, the control sleeve 14 is rotated forward, causing the control sleeve 14 to drive the internally fixed gear 17 to rotate. The internal gear 17 then drives each meshing external gear 18 to rotate synchronously. The external gears 18 then drive multiple screw sleeves 15 to rotate synchronously in the same direction on the fixed plate 12. Due to the setting of the connecting sleeve 20, and the fixed connection between the multiple screws 16 and the connecting sleeve 20, and simultaneously due to the screw sleeve 1... 5 and screw 16 are connected by threads. Screw 16 then drives connecting sleeve 20 to slide. At the same time, one end of screw 16 no longer presses against one-way plate 6. Then, the air pump is turned on, causing it to draw air. The inside of connecting pipe 5 and fixed pipe 4 is in a negative pressure state, which pulls one-way plate 6, causing it to slide along fixed rod 13. One-way plate 6 and fixed plate 12 cooperate to compress the push spring 8 sleeved on the outside of screw 16. Then, one-way plate 6 moves to the other side of air inlet groove 7, and air inside suction cup 3 enters. The air enters the fixed chamber 2, then follows the air in the fixed chamber 2 into the fixed pipe 4, then through the air inlet slot 7 into the through slot 11 inside the fixed rod 13, then through multiple connecting slots 10 into the connecting pipe 5, and finally through the air outlet slot 9 into the suction pump and then discharged. After the suction cup 3 is firmly attached to one side of the wall, the control sleeve 14 is rotated in the reverse direction. Through the cooperation of the internal gear 17 and the external gear 18, the screw sleeve 15 is driven to rotate in the reverse direction on the fixed plate 12. Then the screw 16 will drive the connecting sleeve 20 to rotate in the reverse direction. The slide resets the screw 16, which then pushes the one-way plate 6 to slide along the fixed rod 13. The one-way plate 6 then pulls the push spring 8 to reset, and the one-way plate 6 is pressed against the air inlet 7, causing it to move to the original side. This allows the one-way plate 6 to re-close the fixed pipe 4 and the connecting pipe 5. Then, the rotation control sleeve 14 is stopped, the air pump is turned off, and the air pump can be removed. This effectively prevents the entry of outside air, ensuring the stable adsorption of the suction cup 3, and thus ensuring the stable installation of the mother tape 1 and the daughter tape 19.

[0041] In summary, when using or operating the entire device: First, ensure the wall is smooth and clean. Then, fix the main tape 1 to one side of the fixing chamber 2. Next, attach the multiple suction cups 3 to the wall. Then, connect the external air pump to the connecting pipe 5. Then, create a negative pressure inside the fixing chamber 2 and the suction cups 3, so that the suction cups 3 are firmly attached to the wall. Then, seal the fixing pipe 4 and the connecting pipe 5. Then, remove the external air pump. Finally, attach the sub-tape 19 to one side of the main tape 1.

[0042] When a vacuuming operation is required, first securely connect the vacuum pump input end to the connecting pipe 5. Then, rotate the control sleeve 14 forward, causing the control sleeve 14 to drive the internally fixed gear 17 to rotate. The internal gear 17 then drives each meshing external gear 18 to rotate synchronously. The external gears 18 then drive multiple screw sleeves 15 to rotate synchronously in the same direction on the fixed plate 12. Due to the setting of the connecting sleeve 20 and the fixed connection between the multiple screws 16 and the connecting sleeve 20, and the screw sleeves 15 and screws... 16 is connected via a thread, and then the screw 16 will drive the connecting sleeve 20 to slide. At the same time, one end of the screw 16 will no longer press against the one-way plate 6. Then, the air pump is turned on, so that the air pump draws air, and then the inside of the connecting pipe 5 and the fixed pipe 4 is in a negative pressure state, which pulls the one-way plate 6, so that the one-way plate 6 slides along the fixed rod 13. The one-way plate 6 and the fixed plate 12 cooperate to compress the push spring 8 sleeved on the outside of the screw 16. Then the one-way plate 6 moves to the other side of the air inlet groove 7, and then the air inside the suction cup 3 enters the fixed plate 13. In chamber 2, the air then enters the fixed pipe 4 along with the air in the fixed chamber 2, then enters the through-hole 11 inside the fixed rod 13 through the air inlet slot 7, then enters the connecting pipe 5 through multiple connecting slots 10, and finally is drawn into the air pump through the air outlet slot 9 and discharged. After the suction cup 3 is firmly attached to one side of the wall, the control sleeve 14 is rotated in the opposite direction. Through the cooperation of the internal gear 17 and the external gear 18, the screw sleeve 15 is driven to rotate in the opposite direction on the fixed plate 12. Then the screw 16 will drive the connecting sleeve 20 to rotate in the opposite direction. After sliding reset, screw 16 pushes one-way plate 6 to slide reset along fixed rod 13. Then one-way plate 6 pulls push spring 8 to reset. One-way plate 6 is then pressed, causing it to move to the original side of air inlet slot 7, so that one-way plate 6 re-closes fixed pipe 4 and connecting pipe 5. Then stop rotating control sleeve 14, turn off air pump, and then remove air pump. This effectively prevents the entry of outside air, ensures stable adsorption of suction cup 3, and thus ensures stable installation of mother tape 1 and daughter tape 19.
