Description

Technical Field

[0001] This utility model relates to the field of suction cup device technology, specifically a suction cup base device. Background Technology

[0002] Suction cup base devices, due to their ability to achieve adsorption and fixation without additional power, are widely used in various fields such as hanging household items, handling industrial parts, and equipment installation and positioning. Their core working mechanism involves changing the internal air pressure of the suction cup to achieve adsorption and detachment of objects. In the prior art, a search reveals that application number "CN202320037003.7" discloses a transmission structure that uses a threaded rod and a pressure transmission nut for threaded connection. This device includes a soft rubber suction cup, a threaded rod, a pressure transmission nut, and an upper cover for the suction cup. Rotating the pressure transmission nut causes the threaded rod to rise and fall, thereby pulling the soft rubber suction cup to create negative pressure for adsorption. It also features a toothed engagement structure between the soft rubber suction cup's convex ring and the upper cover to enhance connection stability.

[0003] However, this existing technology has many shortcomings that cannot be ignored in practical applications:

[0004] 1) The transmission structure is too complex, relying on the meshing of the three-threaded rod and the internal thread of the pressure transmission nut for transmission, and at the same time, the tooth meshing is used to connect the components. This not only increases the precision requirements for the parts processing, but also makes the assembly process cumbersome, directly increasing the product cost.

[0005] 2) After long-term and repeated use, the threaded meshing and tooth meshing structures are prone to problems such as thread wear and tooth deformation, which leads to an increase in transmission clearance. It is difficult to maintain a stable locking pressure of the soft rubber suction cup, resulting in a decrease in suction force and affecting the reliability of use. The support structure design is relatively simple, relying only on the rigidity of the suction cup cover itself for support, lacking special reinforced support components. The overall structural strength is insufficient. After bearing a certain weight or long-term use, the suction cup cover is prone to deformation and uneven force on the soft rubber suction cup, which further aggravates the decrease in suction force and shortens the service life of the device. Utility Model Content

[0006] The purpose of this invention is to provide a suction cup base device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a suction cup base device, comprising a soft rubber suction cup for adsorption, a suction cup upper cover being pressed against the top edge of the soft rubber suction cup, two sets of support columns being symmetrically fixedly connected to the top edge of the suction cup upper cover, and an upper cover connecting cover being fixedly connected to the top of the four support columns by screws, a soft rubber suction cup skeleton being provided inside the suction cup upper cover, the bottom end of the soft rubber suction cup skeleton being connected to the middle of the top end of the soft rubber suction cup, a connecting rod being fixedly connected to the top end of the soft rubber suction cup skeleton, the connecting rod passing through a through hole provided in the suction cup upper cover and positioned between the suction cup upper cover and the upper cover connecting cover, a pin hole being opened at the top of the connecting rod, and a pin being inserted into the pin hole; a pressure device is also provided between the suction cup upper cover and the upper cover connecting cover, which is fitted outside the connecting rod and the pin. The transmission sleeve has two curved baffles symmetrically fixedly connected inside. One end of each baffle has a straight section. A rotation guide groove is formed between the baffle and the inner wall of the curved bottom of the pressure transmission sleeve. The two ends of the pin are respectively guided and slidably connected to the two rotation guide grooves. Two limiting plates for limiting the rotation range of the pin are also symmetrically fixedly connected inside the pressure transmission sleeve. Two suction cup switch handles passing through adjacent support columns are fixedly connected to the outside of the pressure transmission sleeve. When the pin rotates to the straight section of the baffle, the connecting rod drives the soft rubber suction cup frame to the bottom, allowing the soft rubber suction cup to expel air and adhere to the object. When the pin rotates to the other end of the baffle away from the straight section, the connecting rod drives the soft rubber suction cup frame to the top, allowing the soft rubber suction cup to intake air and detach from the object.

[0008] As a preferred embodiment of this utility model: the bottom of the pressure transmission sleeve is symmetrically provided with mounting blind holes, and positioning glass beads are rotatably embedded inside the two mounting blind holes.

[0009] As a preferred embodiment of this utility model: the top of the soft rubber suction cup skeleton is also provided with an annular groove, and the surface of the annular groove is provided with a plurality of positioning holes at equal intervals. The bottom of the positioning glass bead is rolled and connected to the annular groove, and the positioning glass bead is positioned after rolling into the positioning hole.

[0010] As a preferred embodiment of this utility model: the connecting rod is a non-cylindrical rod, and the shape of the through hole is adapted to the shape of the connecting rod.

[0011] As a preferred embodiment of this utility model: the top of the upper cover connecting cover is provided with an opening opposite to the position of the connecting rod, and the surface of the upper cover connecting cover is also engraved with unlocking and locking marking grooves.

[0012] As a preferred embodiment of this utility model: the top edge of the soft rubber suction cup is provided with a plurality of evenly distributed first teeth, and the bottom edge of the upper cover of the suction cup is provided with a plurality of evenly distributed second teeth. When the soft rubber suction cup and the upper cover of the suction cup are pressed together, the second teeth engage with the first teeth.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This utility model sets a baffle inside the pressure transmission sleeve. The baffle and the inner wall of the arc-shaped bottom of the pressure transmission sleeve form a rotating guide groove. This structure can accurately constrain the movement trajectory of the pin, so that the pin always slides smoothly along the preset trajectory during the transmission process. This effectively reduces the friction loss between the transmission components. Even after repeated use, the matching accuracy between the pin and the rotating guide groove can still be guaranteed. This ensures that the locking pressure of the soft rubber suction cup is always consistent with the new device. This effectively solves the problem of suction force attenuation caused by component wear in the prior art. At the same time, the four sets of support columns symmetrically fixedly connected to the top edge of the suction cup cover adopt a uniformly distributed layout design, which can evenly distribute the pressure generated during the adsorption process to each support point. This not only significantly enhances the connection stability between the suction cup cover and the upper cover connecting cover, but also greatly improves the structural strength of the entire device. This effectively avoids structural deformation during long-term use or under load, and ensures the durability of the adsorption effect.

[0015] 2) This utility model adopts a lifting transmission method using a pressure transmission sleeve and a connecting rod. Compared with the complex structure of threaded rod and tooth meshing combined in the prior art, it greatly simplifies the composition of the transmission system, eliminates cumbersome processes such as high-precision thread processing and tooth processing, and reduces the number of key components. This not only reduces the difficulty and cost of parts processing, but also simplifies the product assembly process, significantly improves production efficiency, and effectively reduces product cost. At the same time, the simple transmission structure reduces the contact friction points in the transmission process, reduces the probability of failure, and improves the smoothness of transmission. Combined with the precise limitation of the pin rotation range by the limit plate, it makes operation more convenient and reliable. While ensuring that the product performance is superior to the prior art, it also takes into account economic practicality and service life, and has stronger market competitiveness.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0026] Please see Figures 1-8A suction cup base device includes a soft rubber suction cup 100 for adsorption. A suction cup upper cover 110 is pressed against the top edge of the soft rubber suction cup 100. Two sets of support columns 120 are symmetrically fixedly connected to the top edge of the suction cup upper cover 110. The top of the four support columns 120 is fixedly connected to the upper cover connecting cover 140 by screws 130. A soft rubber suction cup skeleton 150 is provided inside the suction cup upper cover 110. The bottom end of the soft rubber suction cup skeleton 150 is connected to the middle of the top end of the soft rubber suction cup 100. A connecting rod 151 is fixedly connected to the top end of the soft rubber suction cup skeleton 150. The connecting rod 151 passes through a through hole 111 provided in the suction cup upper cover 110 and is placed between the suction cup upper cover 110 and the upper cover connecting cover 140. A pin hole 152 is opened at the top of the connecting rod 151. A pin 160 is inserted and connected inside the pin hole 152.

[0027] Between the upper cover 110 of the suction cup and the upper cover connecting cover 140, there is also a pressure transmission sleeve 200 that is sleeved on the outside of the connecting rod 151 and the pin 160. Two curved baffles 210 are symmetrically fixedly connected inside the pressure transmission sleeve 200. One end of the baffle 210 is provided with a straight section 211. A rotation guide groove 220 is formed between the baffle 210 and the inner wall of the curved bottom of the pressure transmission sleeve 200. The two ends of the pin 160 are respectively guided and slidably connected to the two rotation guide grooves 220. Two limiting plates 230 for limiting the rotation range of the pin 160 are also symmetrically fixedly connected inside the pressure transmission sleeve 200. Two suction cup switch handles 240 that pass through the adjacent support column 120 are fixedly connected to the outside of the pressure transmission sleeve 200.

[0028] When pin 160 rotates to the straight section 211 of baffle 210, connecting rod 151 drives soft rubber suction cup frame 150 to the bottom, allowing air to be expelled from soft rubber suction cup 100 and adsorbing the object. When pin 160 rotates to the other end of baffle 210 away from the straight section 211, connecting rod 151 drives soft rubber suction cup frame 150 to the top, allowing air to be inhaled from soft rubber suction cup 100 and detaching from the object.

[0029] Specifically, in scenarios such as adsorption, after the soft rubber suction cup 100 adheres to the surface of the object to be adsorbed, the user turns the suction cup switch handle 240, causing the pressure transmission sleeve 200, which is sleeved around the connecting rod 151 and the pin 160, to rotate. When the pressure transmission sleeve 200 rotates, the two symmetrically fixed curved baffles 210 inside it rotate synchronously. The rotation guide groove 220 formed by the baffles 210 and the inner wall of the curved bottom of the pressure transmission sleeve 200 causes the pin 160 to slide along the groove. Since the pin 160 is inserted into the pin hole 152 at the top of the connecting rod 151, and the lower end of the connecting rod 151 is connected to the soft rubber suction cup frame... The frame 150 is fixedly connected, and the soft rubber suction cup skeleton 150 is connected to the top center of the soft rubber suction cup 100. When the pin 160 slides to the straight section 211 of the baffle 210, the rotating guide groove 220 forms downward pressure on the pin 160, pushing the connecting rod 151 to move downward along the through hole 111 of the upper cover 110 of the suction cup, thereby driving the soft rubber suction cup skeleton 150 to move down to the bottom, squeezing the soft rubber suction cup 100 to expel the internal air, so that the soft rubber suction cup 100 forms a negative pressure with the surface of the object to achieve stable adsorption. At this time, the limiting plate 230 inside the pressure transmission sleeve 200 restricts the pin 160 from continuing to rotate, avoiding excessive squeezing.

[0030] The support column 120 at the top edge of the suction cup cover 110 is fixed to the upper cover connecting cover 140 by screws 130, providing stable support for the entire transmission structure. When it is necessary to detach from the object, the suction cup switch handle 240 is reversed, the pressure transmission sleeve 200 rotates in the opposite direction, and the pin 160 slides along the rotation guide groove 220 to the other end of the baffle 210 away from the straight section 211. The rotation guide groove 220 drives the pin 160 to move upward, and the soft rubber suction cup frame 150 is pulled up to the top by the connecting rod 151. Air enters the soft rubber suction cup 100, the negative pressure is released, and the object is detached smoothly.

[0031] In this embodiment: the bottom of the pressure transmission sleeve 200 is symmetrically provided with mounting blind holes 250, and positioning glass beads 251 are rotatably embedded inside the two mounting blind holes 250.

[0032] Specifically, as the user repeatedly rotates the suction cup switch handle 240, causing the pressure transmission sleeve 200 to rotate, the positioning glass bead 251 embedded inside the blind hole 250 rotates and continuously contacts the top surface of the soft rubber suction cup frame 150 below as the pressure transmission sleeve 200 rotates. The positioning glass bead 251 uses a rolling contact method instead of sliding contact, which greatly reduces the frictional resistance between the pressure transmission sleeve 200 and the soft rubber suction cup frame 150 when the pressure transmission sleeve 200 rotates. This makes it easier and smoother for the user to rotate the suction cup switch handle 240, avoids jamming, improves the operating feel, reduces wear between parts, and effectively extends the service life of the pressure transmission sleeve 200 and the soft rubber suction cup frame 150.

[0033] In this embodiment: the top of the soft rubber suction cup skeleton 150 is also provided with an annular groove 153, and a plurality of positioning holes 154 are equally spaced on the surface of the annular groove 153. The bottom of the positioning glass bead 251 is rolled and connected to the annular groove 153, and the positioning glass bead 251 is positioned after rolling into the positioning hole 154.

[0034] Specifically, when the user operates the suction cup switch handle 240 to rotate the pressure transmission sleeve 200, the positioning glass bead 251 in the blind hole 250 at the bottom of the pressure transmission sleeve 200 forms a rolling engagement with the annular groove 153 at the top of the soft rubber suction cup frame 150. The annular design of the annular groove 153 is perfectly matched with the rotation trajectory of the pressure transmission sleeve 200, ensuring that the positioning glass bead 251 always rolls smoothly along the annular groove 153 during rotation and will not deviate from the preset trajectory. When the pin 160 slides to the straight section 211 of the baffle 210 and the soft rubber suction cup 100 completes the exhaust adsorption, the positioning glass bead 251 rolls exactly onto one of the surfaces of the annular groove 153. Within the positioning hole 154, under the pressure of the pressure transmission sleeve 200, the positioning glass bead 251 is embedded in the positioning hole 154, achieving precise positioning of the pressure transmission sleeve 200 and preventing accidental rotation during the adsorption state that would cause the suction to fail. When the suction cup switch handle 240 is reversed and the soft rubber suction cup 100 completes the air intake and disengagement, the positioning glass bead 251 rolls to another corresponding positioning hole 154, achieving positioning again. This allows the user to clearly perceive the adsorption and disengagement status, while ensuring that the locking pressure of the soft rubber suction cup 100 is stable during the adsorption process. Even if subjected to slight external force, it will not easily loosen, significantly improving the reliability of the device.

[0035] In this embodiment: the connecting rod 151 is a non-cylindrical rod, and the shape of the through hole 111 is adapted to the shape of the connecting rod 151.

[0036] Specifically, during the entire transmission process of the soft rubber suction cup 100 adsorbing and detaching from the object, the design of the non-cylindrical rod body is precisely matched with the shape of the through hole 111 of the upper cover 110 of the suction cup, playing a key role. When the pressure transmission sleeve 200 drives the pin 160 to move through the rotating guide groove 220, the pin 160 exerts a vertical force on the connecting rod 151, pushing or pulling the connecting rod 151 up and down along the through hole 111. Since the connecting rod 151 is a non-cylindrical structure, the shape of the through hole 111 matches it, which can effectively limit the rotation of the connecting rod 151 during the lifting process, ensuring that the connecting rod 151 always moves smoothly in the vertical direction. This ensures that the soft rubber suction cup frame 150 can evenly drive the soft rubber suction cup 100 to exhaust or intake air, avoiding transmission deviation caused by the rotation of the connecting rod 151, preventing jamming or accelerated wear between the pin 160 and the rotating guide groove 220, and making the force on the soft rubber suction cup 100 more uniform, reducing damage caused by excessive local compression or pulling, improving the accuracy and smoothness of the transmission system, and ensuring the stability and service life of the device in long-term repeated use.

[0037] In this embodiment: the top of the upper cover connecting cover 140 is provided with an opening 141 opposite to the position of the connecting rod 151, and the surface of the upper cover connecting cover 140 is also engraved with an unlocking and locking mark groove 142.

[0038] Specifically, in actual use, the upper cover connecting cover 140 is fixedly connected to the support column 120 by screws 130 to form a closed transmission space. The opening 141 at the top corresponds to the position of the connecting rod 151, providing sufficient space for the lifting and lowering movement of the connecting rod 151, avoiding collision or friction between the connecting rod 151 and the upper cover connecting cover 140 when the connecting rod 151 moves up and down, thus ensuring smooth transmission.

[0039] The unlocking and locking indicator grooves 142 engraved on the surface of the upper cover connecting cover 140 provide users with intuitive operation guidance. When the user moves the suction cup switch handle 240, they can quickly determine whether the device is in the suction-locked state or the unlocked state by observing the corresponding position of the suction cup switch handle 240 and the indicator groove 142. No additional inspection is required, which greatly improves the convenience of operation.

[0040] In this embodiment: the top edge of the soft rubber suction cup 100 is provided with a plurality of evenly distributed first teeth 170, and the bottom edge of the suction cup cover 110 is provided with a plurality of evenly distributed second teeth 180. When the soft rubber suction cup 100 and the suction cup cover 110 are pressed together, the second teeth 180 and the first teeth 170 are engaged and connected.

[0041] Specifically, during the assembly and use of the soft rubber suction cup 100 and the upper cover 110, when the upper cover 110 is pressed against the top edge of the soft rubber suction cup 100, the first tooth 170 and the second tooth 180 mesh together, effectively limiting the relative sliding between the soft rubber suction cup 100 and the upper cover 110, enhancing the sealing and stability of the connection. When the soft rubber suction cup 100 exhausts and adsorbs, a negative pressure is formed inside, and the external air pressure will exert inward pressure on the soft rubber suction cup 100. At this time, the meshing structure of the first tooth 170 and the second tooth 180 can effectively resist the relative displacement caused by the pressure, prevent gaps from appearing between the soft rubber suction cup 100 and the upper cover 110, avoid air entering and causing the negative pressure to fail, ensure the stability of the adsorption force, and make the adsorption effect of the soft rubber suction cup 100 more durable and stable.
