Description

Technical Field

[0001] This utility model relates to the field of industrial tool technology, and more specifically, to a locking variable cavity suction cup device. Background Technology

[0002] Currently, adsorption tools are widely used in industrial production, engineering construction, and maintenance operations, primarily relying on adsorption force to grasp, transport, or fix objects. These tools typically employ a sealed structure and internal pressure adjustment principle, achieving effective adsorption onto the work surface by creating a pressure difference between the inside and outside. In many industries, adsorption tools are widely used due to their ease of operation and minimal risk of damaging the target object, especially in environments requiring frequent disassembly and assembly.

[0003] However, existing adsorption tools still have many shortcomings in practical applications. For example, when dealing with complex structures or objects requiring minimal surface damage, traditional adsorption tools may fail due to insufficient adsorption force, poor sealing performance, and unstable operation. Furthermore, in scenarios requiring stable adsorption force, the lack of a reliable self-locking function makes the tool's adsorption state susceptible to interference from external factors. These technical deficiencies severely impact the effectiveness of adsorption tools, especially in situations requiring frontal disassembly or assembly, or in complex environments.

[0004] At present, there is a need for an adsorption tool that can achieve reliable adsorption under complex operating conditions and has a self-locking function, in order to solve the technical problems of insufficient adsorption force and poor operational stability in the existing technology, and meet the high standard requirements of non-destructive disassembly and assembly of the work object.

[0007] The suction cup device has a cavity space inside the main body for achieving the adsorption function by adjusting the pressure. Its front end has a dovetail groove for fixing the contact rubber sealing ring, the middle part provides an installation platform for the locking device cap, and the rear end is connected to the rear end cover of the suction cup device by bolts.

[0010] The lower end of the locking pin is provided with a boss to cooperate with the spring, and the front end is tapered so as to be inserted into the locking hole of the pusher rod;

[0011] The rear end cover of the suction cup device is located at the tail end of the main body of the suction cup device and is used to support the pusher rod to ensure the stability of its longitudinal movement.

[0012] The release handle moves the locking pin out of the locking hole by pulling, thereby releasing the self-locking state;

[0013] The rubber slider fits tightly against the inner wall of the suction cup device body to ensure the sealing of the cavity;

[0014] The contact rubber sealing ring is fixed to the front end of the suction cup device body through the dovetail groove, and is used to form an airtight seal with the surface of the object to be adsorbed.

[0015] Furthermore, when the pusher rod moves under the pull of the air intake handle, the internal pressure is reduced by the change in the volume of the cavity, thus forming an adsorption force.

[0016] Furthermore, the locking pin is driven by the spring force and automatically inserts into the locking hole to achieve mechanical self-locking when the pusher rod moves to the set position.

[0017] Furthermore, the relief handle is used to pull the locking pin away from the locking hole of the pusher rod to release the pressure inside the cavity.

[0018] Furthermore, the cavity of the suction cup device body changes volume by moving the pusher rod, thereby adjusting the internal pressure to form or release suction force.

[0019] Furthermore, the contact rubber sealing ring forms an airtight seal when it comes into contact with the surface of the object to be adsorbed, thereby ensuring the stability of the adsorption process.

[0020] The beneficial effects of the technical solution provided by this utility model embodiment are:

[0021] This invention provides a locking variable cavity suction cup device. Through a reasonable structural design, it achieves reliable adsorption and non-destructive assembly / disassembly of target objects under complex working conditions, overcoming problems such as insufficient adsorption force, poor sealing performance, and lack of self-locking function in existing technologies. The cavity structure of the suction cup device body, combined with the movement of the pusher rod, can effectively adjust the internal pressure, thereby providing a strong and stable adsorption force. The cooperation between the locking pin and the pusher rod ensures the mechanical self-locking function in the adsorption state, maintaining a stable adsorption effect even under external disturbances. The contact rubber sealing ring further improves the sealing performance of the device through airtight design, ensuring the safety and reliability of the adsorption process. This invention is not only simple in structure and easy to operate, but also meets the needs of high-precision and high-requirement working scenarios, possessing wide applicability and high practical value.

This device, through optimized adsorption mechanism and mechanical self-locking structure, solves the problems of difficult frontal inspection and easy damage to lamps using traditional tools in existing technologies.

[0027] This embodiment specifically describes the structural design and working principle of the device, in conjunction with the appendix. Figure 1 and attached Figure 2 The technical solution is explained.

[0028] I. Overall Structure of the Device

[0029] The locking variable cavity suction cup device consists of the following components: suction cup device body 9, pusher rod 3, locking device cap 8, locking pin 4, suction cup device rear end cover 10, spring 5, release handle 7, suction handle 11, rubber slider 2, and contact rubber sealing ring 1.

[0030] 1. Suction cup device main body 9

[0031] The suction cup device is the main load-bearing part of the entire device. It is made of high-strength wear-resistant material and its structure includes a front end, a middle part, and a rear end.

[0032] The front end is provided with a dovetail groove to fix the contact rubber sealing ring 1, so that it can form a stable sealing contact with the surface of the object to be adsorbed.

[0033] The middle section is the mounting platform for the locking device cap 8, and also provides guidance for the pusher rod 3 through the internal slide.

[0034] The rear end is connected to the rear end cover 10 of the suction cup device by bolts to ensure that the pusher rod 3 has sufficient support and balance when moving longitudinally.

[0035] The suction cup device has a cavity inside. When the pusher rod 3 is pulled, the volume of the cavity changes, thereby adjusting the internal pressure.

[0036] 2. Thruster lever 3

[0037] The thruster rod is the core moving component that realizes the pressure change in the cavity, and its structure includes:

[0038] The front end is provided with a rubber mounting groove for installing the rubber slider 2 to ensure the sealing of the cavity during the movement of the lever;

[0039] A shoulder is provided in the middle, and a locking hole is machined on the shoulder to cooperate with the locking pin 4 to achieve mechanical self-locking;

[0040] An air intake handle 11 is installed at the tail end, which allows the operator to pull or push the lever to adjust the pressure.

[0041] The design of the thruster rod ensures stable pressure control and reliable locking function during use.

[0042] 3. Locking device cap 8

[0043] The locking device cap is fixed to the middle of the suction cup device body 9 and is tightly connected to the body by bolts.

[0044] The bottom is provided with a spring fixing groove for installing spring 5. One end of the spring is embedded in the fixing groove, and the other end cooperates with the locking pin 4.

[0045] The compact structural design ensures that the spring and locking pin are subjected to uniform force during longitudinal movement.

[0046] 4. Locking pin 4

[0047] The locking pin is a mechanical self-locking component of the device, and its structural design includes:

[0048] The lower end is provided with a boss, which cooperates with the spring 5 to withstand its elastic force and drive the pin to move forward.

[0049] The front end is tapered, which facilitates quick insertion into the locking hole when the shoulder of the pusher rod 3 moves to the set position, thus achieving self-locking.

[0050] The locking pin is used to lock the movement position of the pusher rod, maintain the low pressure inside the cavity, and prevent errors during operation.

[0051] 5. Suction cup device rear end cover 10

[0052] The suction cup device's rear end cap is located at the tail end of the main body and supports the tail structure of the pusher rod. The design of the rear end cap provides precise guidance and support, preventing the pusher rod from becoming unstable due to misalignment.

[0053] 6. Spring 5

[0054] The spring is installed between the locking device cap 8 and the locking pin 4 and is in a compressed state.

[0055] The spring force drives the locking pin to move longitudinally, so that it can quickly insert into the locking hole when the pull rod moves to the set position, thus achieving the locking effect.

[0056] 7. Relieve the discomfort of the handle 7

[0057] The release handle is used to release the self-locking state of the device. It is designed as a lever structure. By pulling the release handle, the locking pin 4 can be moved out of the locking hole, thereby releasing the low pressure state in the cavity.

[0058] 8. Inhalation handle 11

[0059] The suction handle is connected to the tail end of the pusher rod 3, allowing the operator to precisely control the rod. By pulling or pushing the suction handle, the volume of the cavity can be changed, thereby adjusting the suction force of the device.

[0060] 9. Rubber slider 2

[0061] The rubber slider is installed in the rubber mounting groove of the pusher rod 3 and fits tightly with the inner wall of the suction cup device body 9 to ensure the sealing of the cavity.

[0062] 10. Contact rubber seal 1

[0063] The contact rubber sealing ring is fixed to the front end of the suction cup device body 9 through a dovetail groove, forming an airtight seal when it comes into contact with the surface of the object to be adsorbed, thereby ensuring the stability of the adsorption process.

[0064] II. Working Principle of the Device

[0065] 1. Adsorption process

[0066] Make the contact rubber sealing ring 1 contact the surface of the snap ring lamp, so that the suction cup device body 9 is perpendicular to the lamp;

[0067] Pull the suction handle 11 to move the thruster lever 3 backward, gradually increasing the cavity volume and reducing the internal pressure;

[0068] Under low pressure, a pressure difference is formed inside and outside the cavity, which generates a strong adsorption force, allowing the device to be firmly adsorbed onto the surface of the lamp.

[0069] 2. Self-locking pressure holding process

[0070] When the pusher rod 3 moves to the set position, the locking hole on its shoulder aligns with the locking pin 4;

[0071] The locking pin automatically springs into the locking hole under the action of spring 5, realizing mechanical self-locking and locking the low-pressure state of the cavity.

[0072] The self-locking process requires no additional operation, ensuring stable and long-lasting adsorption.

[0073] 3. Pressure release process

[0074] Operate the release handle 7 to move the locking pin 4 out of the locking hole and release the self-locking state;

[0075] Push the inhalation handle 11 to push the thruster lever 3 back to the initial position, the cavity volume decreases, and the internal pressure returns to the same state as the outside;

[0076] Once the adsorption force disappears, the device detaches from the surface of the lamp.

[0077] III. Application Scenarios of the Device

[0078] 1. Installation and removal of spring-loaded lamps on high-speed trains

[0079] This device is mainly used for the disassembly and assembly of spring-loaded lamps inside the passenger compartment of high-speed trains. It simplifies the operation process by using a front-view inspection method, avoiding scratches or damage to the lamps that may be caused by traditional tools.

[0080] The suction cup device allows for quick adsorption and removal of the lamps, solving the problem of cumbersome operation from the back.

[0081] 2. Glass or tile installation in the decoration industry

[0082] In glass or tile installation operations, this device can effectively assist in the handling and fixing of objects through its strong adsorption force and mechanical self-locking function.

[0083] It is easy to operate and suitable for a variety of surface materials.

[0084] IV. Technological Advantages

[0085] Mechanical self-locking function: The device automatically locks the low-pressure state inside the cavity through the cooperation of the locking pin and the pusher rod, ensuring stable adsorption force without the need for continuous external force operation.

[0086] Wide applicability: Suitable for the maintenance of lights on high-speed trains and other scenarios requiring adsorption assistance, such as glass installation and tile handling.

[0087] Simple structure and easy operation: The device has a compact design and is easy to operate, allowing users to quickly master its use.
