Description

Technical Field

[0001] The invention relates to the technical field of unpowered suction cups, in particular to a quick-detachable unpowered suction cup with a self-locking function. Background Art

[0002] The quick-release unpowered vacuum suction cup is a specially designed unpowered vacuum suction cup, which is characterized by rapid disassembly and installation. This design makes it very useful in situations where the adsorbent needs to be frequently replaced or where temporary fixation is required.

[0003] The disclosure discloses an aluminum non-powered vacuum suction cup with announcement number CN 212245285 U. The aluminum non-powered vacuum suction cup can create a negative pressure environment inside the device without using a vacuum pump, thereby ensuring that the aluminum is firmly fixed, has a simple structure, and is of low cost.

[0004] The aluminum unpowered vacuum suction cup utilizes a connecting rod to drive the piston to move, and then utilizes the gravity of the aluminum itself to cause the shell and the piston to move relative to each other, thereby automatically creating a negative pressure environment to absorb objects. When an external object pulls the connecting rod, there is no device to limit the position of the connecting rod, so that when the object sucked by the suction cup is moved, when the connecting rod is vibrated up and down, the object is easy to fall off the suction cup, causing the object to be easily damaged, and therefore improvement is needed. Summary of the invention

[0005] The object of the present invention is to provide a quick-release unpowered suction cup with a self-locking function to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the top of the first spring is fixedly connected to the top of the manual pump, and the bottom of the first spring is fixedly connected to the top of the sealing disk. When the pull plate drives the pull rod and the sealing disk to move upward, the sealing disk can squeeze the first spring. When the limiting rack is away from the fixed rack, the first spring can drive the sealing disk to move downward, so that the sucked objects can be separated from the suction cup body.

[0008] Preferably, the left side of the second spring is fixedly connected to the right side of the movable plate, and the right side of the second spring is fixedly connected to the left side of the fixed plate. When the fixed rack does not squeeze the limiting rack, the second spring can drive the limiting rack through the movable plate to be inserted between the fixed racks to limit the pull rod.

[0009] Preferably, the moving mechanism includes a base plate, which is fixedly connected to the top of the manual pump, a double-axis cylinder is fixedly connected to the middle of the top of the base plate, sliding plates are fixedly connected to the left and right sides of the double-axis cylinder, a push plate is provided on the left side of the sliding plate, the left side of the push plate and the right side of the sliding plate are fitted together, and the push plate is fixedly connected to the front side of the pull plate.

[0010] Preferably, a fixing groove corresponding to the movement track of the sliding plate is opened inside the bottom plate, and the sliding plate is slidably connected inside the fixing groove. The opening of the fixing groove makes the sliding plate more stable during the movement.

[0011] Preferably, the adjusting mechanism comprises a bidirectional threaded rod, which is rotatably connected to the inner side of the fixed frame, a rotating disk is fixedly connected to the left side of the bidirectional threaded rod, a movable frame is threadedly connected to the outer periphery of the bidirectional threaded rod, a limiting rod is slidably connected to the inner back end of the movable frame, a first threaded rod is slidably connected to the inside of the movable frame, a suction cup body is fixedly connected to the bottom of the first threaded rod, a transmission tube is fixedly connected to the inner side of the suction cup body, the top of the transmission tube is fixedly connected to the bottom of the manual pump, a nut is threadedly connected to the outer periphery of the bidirectional threaded rod, a partition is slidably connected to the outer periphery of the bidirectional threaded rod, and the partition is fixedly connected to the inner side of the fixed frame.

[0012] Preferably, there are four first threaded rods, and nuts are threadedly connected to the periphery of the four first threaded rods. There are eight nuts, and the eight nuts are respectively threadedly connected to the periphery of the four first threaded rods.

[0013] Preferably, a fixing hole corresponding to the size of the bidirectional threaded rod is opened on the left side inside the fixing frame, and the bidirectional threaded rod is rotatably connected to the inside of the fixing hole. Through the opened fixing hole, when the rotating disk rotates, the bidirectional threaded rod can be driven to rotate.

[0014] Compared with the prior art, the present invention provides a quick-release unpowered suction cup with a self-locking function, which has the following beneficial effects: 1. The quick-release non-powered suction cup with a self-locking function has a self-locking mechanism. When the suction cup body contacts the surface of an object, the pull plate drives the pull rod and the sealing plate to move upward, so that the sealing plate can squeeze the first spring. When the pull rod moves upward, the fixed rack can squeeze the limit rack, so that the limit rack drives the sliding rod to move through the moving plate, so that the moving plate can squeeze the second spring. When the fixed rack does not squeeze the limit rack, the second spring can drive the limit rack through the moving plate to be inserted between the fixed racks to limit the pull rod. After the device absorbs the object, when it is shaken up and down during transportation, the sucked object is not easy to separate from the suction cup body to cause damage to the object.

[0015] 2. The quick-release non-powered suction cup with a self-locking function, through the provided moving mechanism, when it is necessary to disassemble the object, open the double-axis cylinder, so that the double-axis cylinder drives the push plate to move through the sliding plate, so that the push plate can drive the fixed plate to move, and the fixed plate drives the moving plate to move through the sliding rod, so that the moving plate can drive the limiting rack away from the inside of the fixed rack, and the first spring drives the sliding rod to move downward through the sealing disk, so that the sucked object is away from the suction cup body, so that the object can be quickly disassembled.

[0016] 3. The quick-release non-powered suction cup with a self-locking function has an adjusting mechanism. When it is necessary to adjust the suction position of the suction cup body, the bidirectional threaded rod is driven to rotate by the rotating disk, so that the bidirectional threaded rod drives the suction cup body to move through the movable frame and the first threaded rod, so that the suction position of the suction cup body can be adjusted. When it is necessary to adjust the height of the suction cup body, the first threaded rod is moved upward and the nut is rotated so that the nut can limit the first threaded rod, so that the height of the suction cup body can be adjusted.
