It is commonly used in industrial automated production lines to improve work efficiency and ensure operator safety.

[0003] The patent application CN221488087U discloses an LEL safety controller, including a fixed base, a controller body inserted into the outer surface of a limiting block, a limiting groove at the bottom of the controller body, sliding grooves on both the front and rear ends of the fixed base, a fixed block fixedly connected to the end of the limiting post away from the inner wall of the sliding groove, a spring sleeved on the outer surface of the limiting post, rectangular grooves on both the upper and lower ends of the mounting plate, the end of the spring fitting against the inner wall of the rectangular groove, a locking block on the side surface of the mounting plate, and a locking groove on the side surface of the fixed base. This invention, by setting the limiting post, spring, and mounting plate, improves the convenience of the fixed base connection; by setting the limiting block, limiting groove, and limiting frame, improves the stability of the controller body connection; and by removing the restriction of the limiting frame on the controller body, it facilitates disassembly and maintenance of the controller body.

[0004] The aforementioned patent improves the stability of the controller body connection and removes the restriction of the limit frame on the controller body, facilitating disassembly and maintenance. However, due to the lack of necessary protective measures in the button structure or the imperfect operation linkage mechanism, operators may start the equipment without being fully prepared or by accidentally touching the switch button. This accidental touch may cause the fixture to move suddenly, resulting in improper workpiece clamping, equipment damage, or even personal injury to the operator. Utility Model Content

[0005] The purpose of this utility model is to provide a safe pneumatic clamp controller, which aims to solve the problem in the prior art that such accidental touch behavior may cause the clamp to move suddenly, resulting in workpiece not being clamped properly, equipment damage, or even personal injury to the operator.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A safety pneumatic clamp controller, comprising:

[0008] Pneumatic clamp starter controller;

[0009] A switch button is located on one side of the pneumatic clamp starter controller;

[0010] The contact mechanism includes an anti-accidental contact housing, a contact operating sleeve, a contact threaded groove, a threaded rotating cylinder, a polygonal slide, a rotating block, and a button pressing block. The anti-accidental contact housing is fixedly connected to one side of the pneumatic clamp start controller. The contact operating sleeve is fixedly connected to one side of the anti-accidental contact housing. The contact threaded groove is fixedly connected to the inner wall of one side of the contact operating sleeve. The threaded rotating cylinder is threadedly connected to the contact threaded groove. The polygonal slide is opened at one side of the threaded rotating cylinder. The rotating block is slidably connected to the polygonal slide. The button pressing block is located at one side of the rotating block and contacts the switch button.

[0011] As a preferred embodiment of this utility model, a pressing sleeve is fixedly connected to one side of the rotating block, and a compression return spring is fixedly connected to one side of the pressing sleeve and one side of the inner wall of the threaded rotating cylinder.

[0012] As a preferred embodiment of this utility model, a rotating extrusion block is fixedly connected to one side end of the pressing sleeve, and the rotating extrusion block is elongated.

[0013] As a preferred embodiment of this utility model, a threaded cylinder reset airbag is fixedly connected to the inner side wall of the contact operating sleeve, and an airbag compression block is fixedly connected to one side end of the threaded rotating cylinder. When the threaded rotating cylinder rotates, the airbag compression block squeezes the threaded cylinder reset airbag to one side.

[0014] As a preferred embodiment of this utility model, a limiting groove is provided on one side of the rotating block, and a rotating plate is rotatably connected in the limiting groove. The button pressing block is fixedly connected to one side of the rotating plate.

[0015] As a preferred embodiment of this utility model, a button return spring is fixedly connected to one side of the rotating plate and one side of the switch button.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this solution, by setting up an anti-accidental activation shell, a threaded rotating cylinder, and a button pressing block, the operator must complete two actions, rotation and pressing, to trigger the start, thus avoiding accidental start-up caused by accidental contact or improper operation, and significantly improving operational safety.

[0018] 2.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A safety pneumatic clamp controller, comprising:

[0030] Pneumatic clamp starter controller 1;

[0031] Switch button 2 is located on one side of the pneumatic clamp start controller 1;

[0032] The contact mechanism includes an anti-accidental contact housing 3, a contact operating sleeve 4, a contact threaded groove 5, a threaded rotating cylinder 6, a polygonal slide 7, a rotating block 8, and a button pressing block 10. The anti-accidental contact housing 3 is fixedly connected to one side of the pneumatic clamp start controller 1. The contact operating sleeve 4 is fixedly connected to one side of the anti-accidental contact housing 3. The contact threaded groove 5 is fixedly connected to the inner wall of one side of the contact operating sleeve 4. The threaded rotating cylinder 6 is threadedly connected to the contact threaded groove 5. The polygonal slide 7 is opened on one side of the threaded rotating cylinder 6. The rotating block 8 is slidably connected to the polygonal slide 7. The button pressing block 10 is located on one side of the rotating block 8 and is in contact with the switch button 2.

[0033] In a specific embodiment of this utility model, a safety pneumatic clamp controller is provided, including a pneumatic clamp start controller 1, a switch button 2 located on one side of the pneumatic clamp start controller 1, a contact mechanism located on one side of the pneumatic clamp start controller 1 and cooperating with the switch button 2, an anti-accidental contact housing 3 fixedly connected to one side of the pneumatic clamp start controller 1, a contact operation sleeve 4 fixedly connected to one side of the anti-accidental contact housing 3, a contact threaded groove 5 fixedly connected to one side of the inner wall of the contact operation sleeve 4, a threaded rotating cylinder 6 threadedly connected to the contact threaded groove 5, a polygonal slide groove 7 opened on one side of the threaded rotating cylinder 6, a rotating block 8 slidably connected to the polygonal slide groove 7, and a button pressing block 10 located on one side of the rotating block 8 and in contact with the switch button 2. In specific operation, when the operator needs to start the pneumatic clamp, they first need to rotate the screw... The rotating cylinder 6 aligns the button pressing block 10 with the switch button 2, placing it in a pressable state. At this point, the operator must manually press the button pressing block 10 to trigger the switch button 2, thus controlling the pneumatic clamp. If the operator does not rotate the cylinder, the distance between the button pressing block 10 and the trigger switch button 2 will be too long, preventing alignment with the switch button 2 and effectively preventing accidental activation. This invention forms a physical isolation structure by setting an anti-accidental activation shell 3 and a contact operation sleeve 4, avoiding accidental activation caused by unintentional contact. The cooperation between the contact threaded groove 5 and the threaded rotating cylinder 6 enables adjustable positioning control of the button pressing block 10, ensuring that the activation action can only be completed under correct operating procedures. The sliding connection of the rotating block 8 within the polygonal slide groove 7 ensures the structural stability of the button pressing block 10 during rotation, improving the accuracy and reliability of the operation.

[0034] Please refer to the details. Figures 1-5A pressing sleeve 9 is fixedly connected to one side of the rotating block 8, and a compression return spring 14 is fixedly connected to one side of the pressing sleeve 9 and one side of the inner wall of the threaded rotating cylinder 6.

[0035] In this embodiment: when the operator rotates the threaded rotating cylinder 6 to align the button pressing block 10 with the switch button 2, and continues to press the pressing sleeve 9, the pressing return spring 14 is compressed, and the button pressing block 10 pushes the switch button 2 to complete the start operation; when the operator releases the pressing action, the pressing return spring 14 returns to its original shape, pushes the pressing sleeve 9 to reset, and drives the button pressing block 10 to disengage from the switch button 2, thereby realizing the automatic reset function and preventing misoperation caused by prolonged button pressing. This structural design not only improves the convenience of operation, but also enhances the safety and stability of the device, and is suitable for industrial automation equipment with high requirements for operational safety.

[0036] Please refer to the details. Figures 1-5 A rotating extrusion block 11 is fixedly connected to one side end of the pressing sleeve 9. The rotating extrusion block 11 is long and narrow.

[0037] In this embodiment, the rotating squeezing block 11 is designed as a long strip structure, which makes it easy for the operator to hold and apply rotation and pressing pressure, improving the convenience and stability of operation. At the same time, this structure can effectively prevent accidental operation caused by finger slippage, enhancing the safety of operation. Through the dual operation mechanism of rotation and pressing of the rotating squeezing block 11, the button squeezing block 10 can only trigger the switch button 2 after the complete operation process is executed, further preventing the possibility of accidental activation.

[0038] Please refer to the details. Figures 1-5 A threaded cylinder reset airbag 12 is fixedly connected to the inner side wall of the contact operating sleeve 4, and an airbag compression block 13 is fixedly connected to one side end of the threaded rotating cylinder 6. When the threaded rotating cylinder 6 rotates, the airbag compression block 13 squeezes the threaded cylinder reset airbag 12 to one side.

[0039] In this embodiment: when the operator rotates the squeezing block 11 to drive the threaded rotating cylinder 6 to rotate, the threaded rotating cylinder 6 moves inward along the contact threaded groove 5. At this time, the airbag squeezing block 13, which is fixedly connected to the threaded rotating cylinder 6, moves accordingly and squeezes the threaded cylinder reset airbag 12, causing it to deform and store elastic potential energy. When the operator releases the squeezing block 11, the threaded cylinder reset airbag 12 returns to its original state, releases the stored energy, and pushes the airbag squeezing block 13 and the threaded rotating cylinder 6 to reset, returning them to their initial positions. This causes the button squeezing block 10 to disengage from the switch button 2, realizing the function of automatically disconnecting the control signal.

[0040] Please refer to the details. Figures 1-5A limiting groove 16 is provided on one side of the rotating block 8, and a rotating plate 17 is rotatably connected in the limiting groove 16. The button pressing block 10 is fixedly connected to one side of the rotating plate 17.

[0041] In this embodiment, the limiting groove 16 limits the rotation angle of the rotating plate 17 to prevent the button pressing block 10 from deviating from the pressing position of the switch button 2 due to excessive rotation, thereby ensuring the accuracy and safety of operation. This structure also enhances the adaptability of the button pressing block 10 during the pressing process. Even if there is a slight positional deviation of the switch button 2 or an angle error during operation, effective pressing can be achieved through the adaptive rotation of the rotating plate 17.

[0042] Please refer to the details. Figures 1-5 A button return spring 15 is fixedly connected to one side of the rotating plate 17 and one side of the switch button 2.

[0043] In this embodiment: when the operator rotates the pressing block 11 to align the button pressing block 10 with the switch button 2, and continues to press the pressing sleeve 9, the button pressing block 10 pushes the switch button 2 to complete the start action. At this time, the button return spring 15 is stretched and stores elastic potential energy. When the operation is completed, the operator releases the pressing action, the button return spring 15 returns to its deformation, pulls the switch button 2 and the button pressing block 10 to reset, so that they quickly disengage from contact, ensuring that the controller disconnects signal transmission and preventing abnormal operation of the equipment due to button jamming or accidental pressing.

[0044] The working principle and usage process of this utility model are as follows: By setting up a contact mechanism consisting of an anti-accidental contact shell 3, a contact operation sleeve 4, a threaded rotating cylinder 6, a rotating block 8, a button pressing block 10, and multiple reset structures, multiple safety guarantees are achieved for the start-up operation of the pneumatic clamp. During operation, the operator must first rotate the pressing block 11 to align the button pressing block 10 with the switch button 2, and then trigger the controller to start by pressing. During this process, the pressing reset spring 14, the threaded cylinder reset airbag 12, and the button return spring 15 work together to ensure that the button automatically resets and disconnects after being pressed, preventing safety hazards caused by accidental contact or prolonged pressing, thereby improving the safety, stability, and automation of equipment operation.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
