Description

[Technical field]

[0001] The utility model relates to the field of hooks, in particular to an adsorbable hook. [Background technology]

[0002] Suction cup hook is a tool that uses the suction cup principle to fix objects and is widely used in daily life. Suction cup hook fixes it on smooth surfaces such as glass, tiles or metal by generating negative pressure. During operation, the suction cup is pressed against the surface and the air is discharged to form a vacuum, so that the hook is firmly attached to the surface. Existing suction cups discharge air by pressing to form a negative pressure space. This method will cause the suction cup to deform after long-term use, which will affect the adsorption effect. At the same time, the existing other buckle-type suction cups have a complex structure and are inconvenient to assemble. [Contents of the utility model]

[0003] In order to solve the problems of poor adsorption effect and inconvenient assembly of the existing suction cup, the utility model provides an adsorbable hook, which includes a shell, a flexible suction cup, a connecting shaft and a pull rod. A receiving groove is arranged at one end of the shell, and the flexible suction cup is arranged corresponding to the receiving groove.

[0005] A connecting rod is arranged at one end of the pull rod, the connecting rod is engaged in the hook end, and the pull rod is rotatably connected through the connecting rod and the connecting shaft;

[0006] When the pull rod is perpendicular to the flexible suction cup, the flexible suction cup is in a natural state. After the pull rod is rotated to make it parallel to the flexible suction cup, the pull rod pulls the flexible suction cup through the connecting shaft, and the flexible suction cup at least partially protrudes toward the accommodating groove.

[0007] Preferably, one end of the pull rod on which the connecting rod is arranged comprises a first end face and a second end face, and the distance between the first end face and the connecting rod is smaller than the distance between the second end face and the connecting rod;

[0009] Preferably, the adsorbable hook further comprises a spring, the spring is sleeved on the connecting shaft, and two ends of the spring respectively abut against the flexible suction cup and the accommodating groove.

[0010] Preferably, the adsorbable hook further comprises an elastic flower pad, which is arranged in the receiving groove, and two ends of the elastic flower pad abut against the flexible suction cup and the receiving groove respectively.

[0011] Preferably, a connecting groove is provided in the flexible suction cup, and the fixed end of the connecting shaft is clamped in the connecting groove.

[0012] Preferably, an annular groove is further provided at one end of the flexible suction cup away from the accommodating groove, and a filling piece is provided in the annular groove.

[0013] Preferably, the adsorbable hook further comprises a sealing ring, a placement groove is arranged at one end of the flexible suction cup away from the accommodating groove, the sealing ring is arranged in the placement groove, and the sealing ring is arranged around the annular groove.

[0016] Preferably, a through hole is provided at one end of the shell away from the accommodating groove, the through hole is connected to the accommodating groove, and the hook end of the connecting shaft is exposed after passing through the through hole.

[0017] Compared with the prior art, the adsorbable hook provided by the utility model has the following advantages:

[0018] 1. The adsorbable hook provided by the utility model includes a shell, a flexible suction cup, a connecting shaft and a pull rod. A receiving groove is arranged at one end of the shell, and the flexible suction cup is arranged corresponding to the receiving groove. The connecting shaft includes a fixed end and a hook end, the fixed end is connected to the flexible suction cup, and the hook end is exposed after passing through the shell. A connecting rod is arranged at one end of the pull rod, the connecting rod is engaged in the hook end, and the pull rod is rotatably connected through the connecting rod and the connecting shaft.

[0019] When the pull rod is perpendicular to the flexible suction cup, the flexible suction cup is in a natural state. After the pull rod is rotated to make it parallel to the flexible suction cup, the pull rod pulls the flexible suction cup through the connecting shaft, and the flexible suction cup at least partially protrudes toward the accommodating groove.

[0020] When the adsorbable hook is used to adsorb on an object, one side of the flexible suction cup of the adsorbable hook is closely attached to the object. The utility model pulls up the flexible suction cup to make it partially convex, thereby forming a negative pressure space between the object and the flexible suction cup, so that the adsorbable hook can be adsorbed on the object under the action of atmospheric pressure. Since the middle area of ​​the flexible suction cup is pulled each time during adsorption, the part of the periphery of the flexible suction cup that contacts the external object will not affect the sealing of the negative pressure space due to deformation, thereby improving the adsorption effect of the adsorbable hook. At the same time, the hook end of the connecting shaft is connected with the pull rod by snapping, and the pull rod can be easily assembled and connected to the connecting shaft, so that the structure of the adsorbable hook is simple and the assembly is more convenient.

[0021] 2. One end of the pull rod of the utility model that is provided with the connecting rod includes a first end face and a second end face, and the distance between the first end face and the connecting rod is smaller than the distance between the second end face and the connecting rod;

[0022] When the pull rod is perpendicular to the flexible suction cup, the first end face abuts against the shell, and when the pull rod is parallel to the flexible suction cup, the second end face abuts against the shell.

[0023] Since the distance between the first end face and the connecting rod is smaller than the distance between the second end face and the connecting rod, the utility model controls the pulling up or releasing of the flexible suction cup by rotating the pull rod so that different end faces contact the shell. The deformation degree of the flexible suction cup can be accurately controlled by the first end face and the second end face, and a lever structure is approximately formed between the pull rod and the connecting shaft, which can make it easier to pull the flexible suction cup. At the same time, the difference between the first end face and the second end face can give the user a better feel for use, and the user can feel whether the pull is in place when rotating the pull rod.

[0024] 3. The adsorbable hook of the utility model further comprises a spring or an elastic flower pad, which is sleeved on the connecting shaft, and two ends of the spring or the elastic flower pad respectively abut against the flexible suction cup and the accommodating groove.

[0025] By arranging a spring or an elastic flower pad, the flexible suction cup can be helped to reset after the pull rod releases the flexible suction cup, thereby ensuring that the flexible suction cup can return to a natural state.

[0026] 4. The adsorbable hook of the utility model also includes a sealing ring, and a placement groove is provided at one end of the flexible suction cup away from the receiving groove, and the sealing ring is arranged in the placement groove. An annular groove is also provided at one end of the flexible suction cup away from the receiving groove, and a filling piece is arranged in the annular groove. The annular groove can make the flexible suction cup easier to deform and release and recover, and the sealing ring can be arranged around the annular groove to further improve the sealing effect of the negative pressure space.

[0027] The function of the filling piece is to reduce the residual air between the suction cup and the wall, so that at the moment the suction cup is close to the wall, due to the presence of the filling piece, no air will remain in the annular groove, which can reduce the initial air volume and accelerate the formation of negative pressure space. This not only speeds up the adsorption speed during installation, but also enhances the stability in the initial stage of adsorption, ensuring the immediate exertion of adsorption force.

[0028] 5. The housing of the utility model is provided with a avoiding groove at one end relative to the receiving groove, and the pull rod can be stored in the avoiding groove after rotating relative to the hook end, and the pull rod is flush with the outer surface of the housing. By providing the avoiding groove, the adsorbable hook is more compact and more beautiful in appearance when in use.

[0029] 6. The utility model has a storage end extending outward from the shell, a hook connected to the storage end, a slide groove arranged on the storage end, and the hook is engaged in the slide groove. The utility model makes it easier to hang items on the adsorbable hook by arranging the storage end connected to the hook on the shell, and the detachably connected hook can be easily replaced. By replacing different hooks, the adsorbable hook can be used to hang different items.

[0050] To solve the problem of poor adsorption effect and inconvenient assembly of existing suction cups, please refer to Figure 1 to Figure 3 The embodiment of the utility model provides an adsorbable hook 1, which includes a housing 11, a flexible suction cup 18, a connecting shaft 17 and a pull rod 12. A receiving groove 113 is arranged at one end of the housing 11, and the flexible suction cup 18 is arranged corresponding to the receiving groove 113;

[0051] The connecting shaft 17 includes a fixed end 171 and a hook end 172. The fixed end 171 is connected to the flexible suction cup 18. A through hole 115 is provided at one end of the housing 11 away from the receiving groove 113. The through hole 115 is connected to the receiving groove 113. The hook end 172 of the connecting shaft 17 is exposed after passing through the through hole 115.

[0052] A connecting rod 121 is provided at one end of the pull rod 12 . The connecting rod 121 is engaged in the hook end 172 , and the pull rod 12 is rotatably connected to the connecting shaft 17 via the connecting rod 121 .

[0053] When the user assembles the pull rod 12 and the connecting shaft 17, the user presses the flexible suction cup 18 to make it protrude toward the receiving groove 113, thereby increasing the portion of the hook end 172 driving the connecting shaft 17 exposed outside the housing. Since the exposed portion of the hook end 172 is large enough, the user can more easily snap the connecting rod 121 on the pull rod 12 into the hook end 172, which makes the absorbable hook 1 simple in structure and more convenient to assemble.

[0054] Specifically, when the pull rod 12 is perpendicular to the flexible suction cup 18, the flexible suction cup 18 is in a natural state. The pull rod 12 is rotated so that the pull rod 12 is roughly parallel to the flexible suction cup 18. During this process, the pull rod 12 gradually pulls the flexible suction cup 18 through the connecting shaft 17, and finally makes the flexible suction cup 18 at least partially protrude toward the accommodating groove 113.

[0055] When the adsorbable hook 1 is used to adsorb on an object, one side of the flexible suction cup 18 of the adsorbable hook 1 is placed close to the object, and the flexible suction cup 18 is pulled up by rotating the pull rod 12 to make it partially convex, thereby forming a negative pressure space between the object and the flexible suction cup 18, so that the adsorbable hook 1 can be adsorbed on the object under the action of atmospheric pressure. Since the connection area between the flexible suction cup 18 and the fixed end 171 is pulled each time during adsorption, the part of the periphery of the flexible suction cup 18 in contact with the external object will not affect the sealing of the negative pressure space due to deformation, thereby improving the adsorption effect of the adsorbable hook 1.

[0056] Specifically, see Fig. 9 The hook end 172 includes a hook groove 173 and a hook tip 174. The size of the hook groove 173 matches the connecting rod 121, and the connecting rod 121 is clamped in the hook groove 173. At the same time, the distance from the center of the hook groove 173 to the fixed end 171 is greater than the distance from the hook tip 174 to the fixed end 171.

[0057] The size of the hook groove 173 and the connecting rod 121 are adapted to each other so that the connecting rod 121 can be more stably clamped in the hook end 172, thereby preventing the pull rod 12 from loosening during use. At the same time, since the hook tip 174 is lower than the center of the hook groove 173, the hook tip 174 can further prevent the connecting rod 121 from coming out of the hook groove 173.

[0058] Specifically, the connecting shaft 17 is further provided with a weight-reducing groove 175 . By providing the weight-reducing groove 175 , the weight of the connecting shaft 17 can be reduced, thereby increasing the weight that the adsorbable hook 1 can carry.

[0059] For details, please refer to Figure 5 and Figure 8 The pull rod 12 is provided with a connecting rod 121 including a connected rod head 125 and a rod handle 126, and the rod head 125 includes a first end face 122 and a second end face 123. The first end face 122 is perpendicular to the second end face 123, and the distance between the first end face 122 and the connecting rod 121 is smaller than the distance between the second end face 123 and the connecting rod 121.

[0060] When the pull rod 12 is perpendicular to the flexible suction cup 18, the first end face 122 abuts against the shell 11, and when the pull rod 12 is parallel to the flexible suction cup 18, the second end face 123 abuts against the shell 11. Since the distance between the first end face 122 and the connecting rod 121 is smaller than the distance between the second end face 123 and the connecting rod 121, the utility model controls the pulling up or releasing of the flexible suction cup 18 by rotating the pull rod 12 so that different end faces contact the shell 11, and the deformation degree of the flexible suction cup 18 can be accurately controlled by the first end face 122 and the second end face 123. At the same time, the difference between the first end face 122 and the second end face 123 can give the user a better feel for use, and can feel whether the pulling is in place when rotating the pull rod 12.

[0061] Furthermore, an arc surface 124 is provided at the connection between the first end surface 122 and the second end surface 123, and the curvature of the arc surface 124 gradually increases from the first end surface 122 to the second end surface 123. The arc surface 124 makes the pull rod 12 smoother and gentler during the rotation process. And the arc surface 124 has a smaller curvature near the first end surface 122, so that the process of pulling up the flexible suction cup 18 is longer. As the flexible suction cup 18 is gradually pulled up with the curvature, the degree of mutation of the flexible suction cup 18 can be slowed down, and the pulling process is more labor-saving. The arc surface 124 has a larger curvature near the second end surface 123. When the pull rod 12 is rotated to release the flexible suction cup 18, it can be rotated to the first end surface 122 more quickly due to the larger curvature of the arc surface 124.

[0062] Specifically, the rod head 125 is perpendicular to the rod handle 126, and the rod head 125 and the rod handle 126 form an approximately L-shaped structure. This structure can reduce the weight of the pull rod 12, so that the adsorbable hook 1 can carry more weight. At the same time, the L-shaped pull rod 12 can play a lever role during the rotation process. The torque of the rotation force applied by the user to the rod handle 126 is much greater than the torque of the restoring force of the flexible suction cup 18, and the pull rod 12 can make the rotation more labor-saving.

[0063] For details, please refer to Figure 2 and Figure 5 The adsorbable hook 1 further includes a spring 15, which is sleeved on the connecting shaft 17, and the two ends of the spring 15 respectively abut against the flexible suction cup 18 and the receiving groove 113. Further, the adsorbable hook 1 further includes an elastic flower pad 16, which is arranged in the receiving groove 113, and the two ends of the elastic flower pad 16 respectively abut against the flexible suction cup 18 and the receiving groove 113.

[0064] The spring 15 or the elastic flower pad 16 can help the flexible suction cup 18 to return to its original position after the pull rod 12 releases the flexible suction cup 18, thereby ensuring that the flexible suction cup 18 can return to its natural state.

[0065] Specifically, see Figure 6 A holding ring 114 is disposed in the receiving groove 113, and the holding ring 114 abuts against the flexible suction cup 18. When the pull rod 12 pulls the flexible suction cup 18 through the connecting shaft 17, the holding ring 114 abuts against the flexible suction cup 18, so that the flexible suction cup 18 is only partially raised, thereby preventing the entire flexible suction cup 18 and the housing 11 from being displaced to affect the adsorption effect of the adsorbable hook 1.

[0066] Specifically, the flexible suction cup 18 is provided with a protrusion 124 facing the receiving groove 113, and the protrusion 124 is clamped between the housing 11 and the abutting ring 114. In this embodiment, the flexible suction cup 18 is further fixed by providing the protrusion 124, so as to avoid the relative displacement between the flexible suction cup 18 and the housing 11 when the pull rod 12 pulls and affects the sealing effect.

[0067] For details, please refer to Figure 3 and Figure 5 A connection groove 181 is provided in the flexible suction cup 18, and the fixed end 171 of the connecting shaft 17 is clamped in the connection groove 181. By clamping the fixed end 171 in the connection groove 181, the connecting shaft 17 can be more stable when pulling the flexible suction cup 18. Optionally, the fixed end 171 of the connecting shaft 17 and the flexible suction cup 18 are integrally formed by injection molding, which can make the connection between the fixed end 171 and the flexible suction cup 18 more stable.

[0068] Specifically, see Figure 6 , an annular groove 182 is further provided at one end of the flexible suction cup 18 away from the receiving groove 113. When the connecting shaft 17 pulls the flexible suction cup 18, the annular groove 182 is stretched and enlarged so that the flexible suction cup 18 can bulge toward the receiving groove 113. By providing the annular groove 182, the flexible suction cup 18 can be more easily deformed and released and restored. In addition, the negative pressure space between the annular groove 182, the flexible suction cup 18 and the external object is further enlarged, which can improve the adsorption effect of the adsorbable hook 1.

[0069] Further, please combine Figure 5 and Figure 6 A filling piece 184 is placed in the annular groove 182 .

[0070] It can be understood that the role of the filling piece 184 is to reduce the residual air between the suction cup 1 and the wall, so that at the moment when the adsorbable hook 1 is close to the surface of an external object, due to the presence of the filling piece 184, no air will remain in the annular groove 182, which can reduce the initial air volume and accelerate the formation of the negative pressure cavity. This not only speeds up the adsorption speed during installation, but also enhances the stability in the initial stage of adsorption, ensuring the immediate exertion of the adsorption force.

[0071] Specifically, before the adsorbable hook 1 is installed on an external object, the filler 184 is pre-placed in the annular groove 182, and its outer surface is closely fitted with the inner wall of the annular groove 182. The layout design at this time is intended to reduce the volume of air in the initial contact between the adsorbable hook 1 and the external object, laying the foundation for the subsequent formation of a negative pressure space. The existence of the filler 184 is like a pre-set sealing pad, which helps to quickly remove part of the air when the adsorbable hook 1 first contacts the external object, thereby promoting the rapid formation of negative pressure. When the user operates the control member to move the connecting shaft 17 of the adsorbable hook 1 away from the external object, the flexible suction cup 18 begins to deform. Since the flexible suction cup 18 is provided with an annular groove 182, it can be easily bent and expanded, thereby increasing the volume of the annular groove 182. As the annular groove 182 expands, the outer surface of the filler 184, which was originally fitted with the inner wall of the groove, gradually separates from the groove wall. This process effectively increases the cavity volume inside the flexible suction cup 18, forming a larger negative pressure space. At this time, due to the reduction of air volume, a large pressure difference is quickly formed between the flexible suction cup 18 and the external object, that is, the difference between the external atmospheric pressure and the negative pressure formed inside the flexible suction cup 18. This pressure difference generates a strong inward suction force, which firmly adsorbs the adsorbable hook 1 on the surface of the external object.

[0072] For further information, please refer to Figure 2 and Figure 5 The adsorbable hook 1 further includes a sealing ring 19. The end of the flexible suction cup 18 away from the receiving groove 113 is provided with a placement groove 112. The sealing ring 19 is arranged in the placement groove 112. The sealing ring 19 is arranged around the annular groove 182. The sealing ring 19 is arranged around the annular groove 182 to further improve the sealing effect of the negative pressure space.

[0073] For details, please refer to Figure 1 and Figure 6 The housing 11 is provided with a avoiding groove 111 at one end thereof relative to the receiving groove 113, and the pull rod 12 can be received in the avoiding groove 111 after rotating relative to the hook end 172, and the pull rod 12 is flush with the outer surface of the housing 11. By providing the avoiding groove 111, the adsorbable hook 1 is more compact and more beautiful in appearance when in use.

[0074] For further information, see Figure 7 A limit plate 116 is provided in the avoidance groove 111, and the pull rod 12 rotates relative to the hook end 172 in the avoidance groove 111 and abuts against the limit plate 116. The limit plate 116 can give the user a sense of rotation, which is more convenient for the user to use. At the same time, the limit plate 116 can limit the pull rod 12 from further rotation, avoiding excessive stretching of the flexible suction cup 18, so that the adsorbable hook 1 maintains the best use mode.

[0075] Specifically, the through hole 115 is disposed in the avoidance groove 111 , and the hook end 172 passes through the through hole 115 and is engaged with the pull rod 12 in the avoidance groove 111 , so that the structure of the adsorbable hook 1 is more compact and the volume is smaller.

[0076] Specifically, see Figure 1 A storage end 13 is extended outward from the shell 11, and a hook 14 is connected to the storage end 13. By providing the storage end 13 connected to the hook 14 on the shell 11, the hook 14 is extended to the outside away from the shell 11, so as to avoid the shell 11 interfering with the hook 1 for hanging items.

[0077] Furthermore, a slide groove 131 is provided on the storage end 13, and the hook is clamped in the slide groove 131. The detachably connected hook 14 can be easily replaced, and by replacing different hooks 14, the adsorbable hook 1 can be used to hang different items.

[0078] In the embodiment of the utility model, the pull rod 12 and the connecting shaft 17 of the adsorbable hook 1 are engaged with each other through the hook end 172 and the connecting rod 121, so that the structure of the adsorbable hook 1 is simpler and easier to assemble. At the same time, the pull rod 12 pulls the flexible suction cup 18 through the connecting shaft 17 to deform, so that a negative pressure space is formed between the flexible suction cup 18 and the external object, and the flexible suction cup 18 can then be adsorbed on the object. By pulling the flexible suction cup 18 to deform, the stability and adsorption effect of the adsorbable hook 1 are improved.

[0079] Compared with the prior art, the adsorbable hook provided by the utility model has the following advantages:

[0080] 1. The adsorbable hook provided by the utility model includes a shell, a flexible suction cup, a connecting shaft and a pull rod. A receiving groove is arranged at one end of the shell, and the flexible suction cup is arranged corresponding to the receiving groove. The connecting shaft includes a fixed end and a hook end, the fixed end is connected to the flexible suction cup, and the hook end is exposed after passing through the shell. A connecting rod is arranged at one end of the pull rod, the connecting rod is engaged in the hook end, and the pull rod is rotatably connected through the connecting rod and the connecting shaft.

[0081] When the pull rod is perpendicular to the flexible suction cup, the flexible suction cup is in a natural state. After the pull rod is rotated to make it parallel to the flexible suction cup, the pull rod pulls the flexible suction cup through the connecting shaft, and the flexible suction cup at least partially protrudes toward the accommodating groove.

[0082] When the adsorbable hook is used to adsorb on an object, one side of the flexible suction cup of the adsorbable hook is closely attached to the object. The utility model pulls up the flexible suction cup to make it partially convex, thereby forming a negative pressure space between the object and the flexible suction cup, so that the adsorbable hook can be adsorbed on the object under the action of atmospheric pressure. Since the middle area of ​​the flexible suction cup is pulled each time during adsorption, the part of the periphery of the flexible suction cup that contacts the external object will not affect the sealing of the negative pressure space due to deformation, thereby improving the adsorption effect of the adsorbable hook. At the same time, the hook end of the connecting shaft is connected with the pull rod by snapping, and the pull rod can be easily assembled and connected to the connecting shaft, so that the structure of the adsorbable hook is simple and the assembly is more convenient.

[0083] 2. One end of the pull rod of the utility model that is provided with the connecting rod includes a first end face and a second end face, and the distance between the first end face and the connecting rod is smaller than the distance between the second end face and the connecting rod;

[0084] When the pull rod is perpendicular to the flexible suction cup, the first end face abuts against the shell, and when the pull rod is parallel to the flexible suction cup, the second end face abuts against the shell.

[0085] Since the distance between the first end face and the connecting rod is smaller than the distance between the second end face and the connecting rod, the utility model controls the pulling up or releasing of the flexible suction cup by rotating the pull rod so that different end faces contact the shell. The deformation degree of the flexible suction cup can be accurately controlled by the first end face and the second end face, and a lever structure is approximately formed between the pull rod and the connecting shaft, which can make it easier to pull the flexible suction cup. At the same time, the difference between the first end face and the second end face can give the user a better feel for use, and the user can feel whether the pull is in place when rotating the pull rod.

[0086] 3. The adsorbable hook of the utility model further comprises a spring or an elastic flower pad, which is sleeved on the connecting shaft, and two ends of the spring or the elastic flower pad respectively abut against the flexible suction cup and the accommodating groove.

[0087] By arranging a spring or an elastic flower pad, the flexible suction cup can be helped to reset after the pull rod releases the flexible suction cup, thereby ensuring that the flexible suction cup can return to a natural state.

[0088] 4. The adsorbable hook of the utility model also includes a sealing ring, and a placement groove is provided at one end of the flexible suction cup away from the receiving groove, and the sealing ring is arranged in the placement groove. An annular groove is also provided at one end of the flexible suction cup away from the receiving groove. The annular groove can make the flexible suction cup more convenient to deform and release and recover, and the sealing ring is arranged around the annular groove to further improve the sealing effect of the negative pressure space.

[0089] 5. The housing of the utility model is provided with a avoiding groove at one end relative to the receiving groove, and the pull rod can be stored in the avoiding groove after rotating relative to the hook end, and the pull rod is flush with the outer surface of the housing. By providing the avoiding groove, the adsorbable hook is more compact and more beautiful in appearance when in use.

[0090] 6. The utility model has a storage end extending outward from the shell, a hook connected to the storage end, a slide groove arranged on the storage end, and the hook is engaged in the slide groove. The utility model makes it easier to hang items on the adsorbable hook by arranging the storage end connected to the hook on the shell, and the detachably connected hook can be easily replaced. By replacing different hooks, the adsorbable hook can be used to hang different items.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
