Description

Technical Field

[0001] This utility model relates to the field of safety pedal technology, and in particular to an anti-slip safety pedal. Background Technology

[0002] Machine tool safety pedals, as an important safety protection device in the machining field, typically employ a dual-pedal linkage structure. Operators must simultaneously depress both pedals with both feet to start the equipment. This design effectively prevents accidental start-up with one hand through limb restraint, while also forcing operators to maintain a standard working posture, keeping both hands stable within the equipment's control area. Currently, mainstream dual-pedal systems are widely used in industrial settings such as stamping machines and forging equipment, becoming a standardized configuration for ensuring personnel safety.

[0003] Existing safety pedals have revealed significant anti-cheating defects in actual use. Since the pedal triggering mechanism only uses mechanical sensing through pressure threshold, some operators use counterweights, metal clamps, or other foreign objects to press down one side of the pedal for a long time in order to simplify the operation process, and can start the equipment with only one foot. This violation renders the inherent safety function of the dual-pedal design ineffective, causing the equipment to start abnormally when the operator does not maintain the standard posture, which greatly increases the risk of work-related injuries. Therefore, we propose an anti-slip safety pedal. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-slip safety pedal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-slip safety pedal includes a base, a housing fixed to the top of the base, the housing being a hollow cuboid structure, a baffle fixed to the top of the housing, cushioning pads installed at both ends of the top of the housing, anti-slip posts fixed on the cushioning pads, and pedal mechanisms installed at both ends of the top of the housing. The pedal mechanisms penetrate the cushioning pads and are inserted into the interior of the housing, and are slidably connected to the housing. A pressure sensor, a limit switch, a hydraulic damper, and a support spring are installed between the pedal mechanism and the inner bottom of the housing.

[0007] Preferably, the number of anti-slip posts is several groups, and the anti-slip posts pass through the pedal mechanism and are slidably connected to it.

[0008] Preferably, the pedal mechanism includes a connecting post that passes through the buffer pad and the top of the housing. The connecting post is inserted into the interior of the housing and connected to a movable plate. A pedal body is installed on the top of the connecting post, and a sleeve is fixed on the pedal body.

[0009] Preferably, the sleeves are in several sets, and the sleeves are slidably connected to the anti-slip posts.

[0010] Preferably, the pressure sensor, limit switch, hydraulic damper, and support spring are installed between the movable plate and the inner bottom of the housing, with the support spring sleeved on the hydraulic damper.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention achieves the coordinated operation of pressure sensors and limit switches by setting up a linkage detection mechanism for the pedal mechanism, enabling accurate detection of the synchronous triggering state of both pedals and effectively preventing cheating by having one pedal pressed down by foreign objects for a long time. By setting up a composite buffer structure of hydraulic damper and support spring, the invention achieves the effect of dynamically adjusting the pedal rebound force, realizing flexible feedback of the operator's foot pressure. By setting up an array of anti-slip columns with sleeves, the invention achieves multi-dimensional limiting and anti-slip effects, realizing dual locking of the pedal block in the vertical and horizontal directions. Combined with the protective boundary formed by the baffle, the invention comprehensively improves the stability and safety of equipment operation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3A non-slip safety pedal includes a base 1, a housing 2 fixed to the top of the base 1, the housing 2 being a hollow cuboid structure, a baffle 3 fixed to the top of the housing 2, buffer pads 4 installed at both ends of the top of the housing 2, anti-slip posts 5 fixed on the buffer pads 4, and pedal mechanisms 6 installed at both ends of the top of the housing 2. The pedal mechanisms 6 penetrate the buffer pads 4 and are inserted into the interior of the housing 2, and are slidably connected to the housing 2. A pressure sensor 7, a limit switch 8, a hydraulic damper 9, and a support spring 10 are installed between the pedal mechanisms 6 and the inner bottom of the housing 2. The number of anti-slip posts 5 is several sets, and the anti-slip posts 5 penetrate the pedal mechanisms 6 and are slidably connected to them. The pedal mechanism 6 includes a connecting post 61 penetrating the buffer pads 4 and the top of the housing 2, the connecting post 61 being inserted into the interior of the housing 2 and connected to a movable plate 62, a pedal body 63 installed on the top of the connecting post 61, and a sleeve 64 fixed on the pedal body 63. The sleeves 64 are in several sets, and the sleeves 64 are slidably connected to the anti-slip columns 5. The pressure sensor 7, limit switch 8, hydraulic damper 9, and support spring 10 are installed between the movable plate 62 and the inner bottom of the housing 2. The support spring 10 is sleeved on the hydraulic damper 9. By setting a linkage detection mechanism for the pedal mechanism, the pressure sensor and limit switch work together to achieve accurate detection of the synchronous triggering state of the two pedals, effectively preventing cheating behavior such as the pedal being pressed by foreign objects for a long time. By setting a composite buffer structure of hydraulic damper and support spring, the pedal rebound force is dynamically adjusted, achieving flexible feedback of the operator's foot pressure. By setting an array of anti-slip columns with sleeves, a multi-dimensional limiting and anti-slip effect is achieved, realizing the dual locking of the pedal block in the vertical and horizontal directions. Combined with the protective boundary formed by the baffle, the stability and safety of the equipment operation are comprehensively improved.

[0019] When the operator simultaneously presses both pedal bodies 63 with both feet, the connecting column 61 drives the movable plate 62 to move downward. At this time, the pressure sensor 7 detects the downward pressure of the pedal block in real time, and the limit switch 8 senses the displacement stroke synchronously. The hydraulic damper 9 generates progressive resistance during the pedal pressing process. Together with the elastic deformation of the support spring 10, it forms a controllable buffer stroke to ensure that the pedal will not be falsely triggered due to instantaneous impact. The sliding pair formed by the anti-slip column 5 and the sleeve 64 generates lateral restraint force when the pedal is in motion. Through the distributed cooperation of multiple anti-slip column arrays, the risk of horizontal displacement of the pedal block is eliminated, and the angle of the user is supported. When one side of the pedal is abnormally pressed, the detection data of the pressure sensor 7 and the limit switch 8 will exceed the set threshold range, and the system will automatically lock the equipment start function. After the pedal is released, the support spring 10 drives the movable plate 62 to reset, and the hydraulic damper 9 controls the rebound speed to prevent the pedal block from vibrating violently.

[0020] In summary, compared with existing technologies, this utility model achieves the effect of coordinated operation of pressure sensors and limit switches by setting a linkage detection mechanism for the pedal mechanism, realizing accurate detection of the synchronous triggering state of the two pedals and effectively preventing cheating behavior such as long-term suppression of one pedal by foreign objects; by setting a composite buffer structure of hydraulic damper and support spring, the effect of dynamically adjusting the pedal rebound force is achieved, realizing flexible feedback of the operator's foot pressure; by setting an anti-slip column array with sleeves, a multi-dimensional limiting and anti-slip effect is achieved, realizing the dual locking of the pedal block in the vertical and horizontal directions, and together with the protective boundary formed by the baffle, the stability and safety of equipment operation are comprehensively improved.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
