Description

Technical Field

[0001] This utility model relates to a handrail opening detection fixture, and more particularly to a consistency fixture for detecting the opening of a double-opening handrail. Background Technology

[0002] In the field of production consistency testing for double-opening handrails, existing technologies have significant shortcomings and cannot meet the requirements of high-precision automated testing. Specifically, the testing device involved in the existing technology disclosed in CN208953296U, although employing an infrared sensor for time recording, still relies on manual pressing of the armrest to trigger the core opening action. This involves the user pressing and releasing the armrest, which directly introduces uncontrollable human error, causing the opening actions of the two handrails to be unable to achieve true synchronization, thus making it difficult to accurately measure their time consistency.

[0003] The prior art disclosed in CN214844037U provides a more automated opening time detection mechanism, which automatically triggers the button through a push rod module and a pressing head. However, the original design of this mechanism is to time the opening process of a single product. Even if it can be symmetrically arranged to detect two products simultaneously, its technical solution does not include a mechanism for directly comparing and judging the time difference between two independent opening units. Therefore, it cannot directly solve the core problem of the synchronous opening consistency of double-opening handrails.

[0004] In summary, the fundamental flaw in existing technologies lies in the lack of a solution capable of automatically and synchronously triggering double-opening handrails and accurately comparing their opening time differences. Manual triggering leads to asynchrony, while single automatic detection cannot directly determine consistency. This collectively results in a technical dilemma of low reliability of detection results and difficulty in guaranteeing product consistency, urgently requiring an innovative tooling solution to address this core technical problem. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a consistency tooling for detecting the opening of double-opening handrails, aiming to solve the problems of asynchronous opening and low detection accuracy caused by manual operation in the prior art.

[0006] The objective of this utility model can be achieved through the following technical solutions: This utility model provides a consistency fixture for detecting the opening of a double-opening handrail, enabling the detection of the consistency of the opening time of the two handrails. One side of each handrail is equipped with an opening push-button switch. The consistency fixture for detecting the opening of the double-opening handrail includes a base and a component mounted on the base: The opening cylinder is located on the side near the opening push switch; The push plate is connected to the output end of the opening cylinder; Two push rods are provided on the push plate, and the positions of the two push rods correspond to the opening push switch; Two position sensors are used to detect the state when the handrail is fully open; A timer, electrically connected to the opening cylinder and the position sensor, is used to start timing when the output end of the opening cylinder is pushed out, and to end timing when the position sensor detects that the handrail is fully open.

[0007] Furthermore, the position sensor is an infrared position sensor.

[0008] Furthermore, the position detected by the position sensor is the position of the end of the handrail when the handrail is fully open.

[0009] Furthermore, the opening cylinder, push plate, and push rod are all located on the side close to the opening push switch.

[0010] Furthermore, the position sensor is located on the side away from the activation button.

[0011] Furthermore, the pushing direction of the push rod is parallel to the axial direction of the handrail pivot.

[0012] Furthermore, the detection position of the position sensor is any position above half the height of the end of the handrail when the handrail is fully open.

[0013] Furthermore, the consistency fixture for detecting the opening of the double-opening handrail also includes a closing cylinder, a connecting plate connected to the output end of the closing cylinder, and a roller axially connected to the connecting plate; When the output rod of the closing cylinder is pushed out, the roller can press the handrail into the closed state.

[0014] Furthermore, the consistency fixture for detecting the opening of the double-opening handrail also includes a base bracket on the base, and the handrail is limited to the base bracket.

[0015] Furthermore, the handrail is detachably fixed to the base bracket by fasteners. or, The base support is provided with a limiting groove, and the bottom protrusion of the handrail matches the limiting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention significantly improves the accuracy and efficiency of detecting the consistency of opening time of double-opening handrails through an automated synchronous triggering and detection mechanism. Specifically, it utilizes an opening cylinder to drive a push plate and two push rods to synchronously press the handrail's opening switch, completely eliminating the problem of asynchronous triggering caused by differences in pressing sequence or force during manual operation. Simultaneously, two position sensors monitor the fully open state of the handrails in real time, and a timer automatically records the time difference from cylinder action to the handrail's full unfolding, enabling a quantitative assessment of the consistency of double handrail opening. Compared to existing technologies (such as CN208953296U which relies on manual triggering and CN214844037U which lacks dual-target synchronous comparison), this invention not only avoids human error but also simplifies the operation process through an integrated design, greatly improving the reliability and repeatability of the detection results, and providing key technical support for product quality control.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, circuit structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0020] Example 1 This embodiment uses a consistency fixture for detecting the opening of a double-opening handrail to detect the consistency of the opening time of the two handrails 1. One side of each handrail 1 is equipped with an opening push switch 2. The consistency fixture for detecting the opening of the double-opening handrail includes a base 0 and an opening cylinder 3, a push plate 4, two push rods 5, two position sensors 6, and a timer 7 mounted on the base 0. See details below. Figures 1 to 3 .

[0021] An opening cylinder 3 is located on the side near the opening push switch 2; a push plate 4 is connected to the output end of the opening cylinder 3; two push rods 5 are located on the push plate 4, and the positions of the two push rods 5 correspond to the opening push switch 2; two position sensors 6 are used to detect the state of the handrail 1 when it is fully open; a timer 7 is electrically connected to the opening cylinder 3 and the position sensors 6, and is used to start timing when the output end of the opening cylinder 3 is pushed out, and to end timing when the position sensors 6 detect the state of the handrail 1 when it is fully open.

[0022] The core principle lies in the coordinated operation of a pneumatic linkage structure and a sensing timing system to achieve synchronous triggering and precise measurement of the time difference between the two handrails. As shown in the attached diagram, the opening cylinder 3 serves as the power source, with its output rigidly connected to the push plate 4, driving two symmetrically arranged push rods 5 to move synchronously, ensuring that the opening buttons 2 of both handrails are triggered at the same moment. Position sensors 6 are aligned with the end positions of the handrails 1 when they are fully extended. When the handrails rotate to a preset angle, the position sensors 6 detect the change in state and send a signal to the timer 7. The timer uses built-in logic to synchronously capture the action signal of the opening cylinder 3 (timing start point) and the feedback signal of the position sensors 6 (timing end point), automatically calculating the opening time difference between the two handrails. Through the close integration of mechanical synchronization and electronic control timing, the technical challenge of detecting the consistency of dual-target actions is solved.

[0023] In the above technical solution, the timer 7 uses its built-in conventional timing logic (such as signal edge detection and timestamp comparison) to calculate the time interval between the start of cylinder 3 and the triggering of position sensor 6. This logic belongs to existing mature timing control technology and will not be elaborated here.

[0024] The aforementioned timer 7 uses a conventional timing module in the field, such as a timing control unit based on a microprocessor or programmable logic controller (PLC). Its interval calculation function, which receives the action signal of the opening cylinder 3 as the timing start point and the status signal of the position sensor 6 as the timing end point, is existing technology.

[0025] In specific implementation, the position sensor 6 is an infrared position sensor. The detection position of the position sensor 6 is the position of the end of the handrail 1 when it is fully open. The opening cylinder 3, push plate 4, and push rod 5 are all located on the side close to the opening push switch 2. The position sensor 6 is located on the side away from the opening push switch 2. The pushing direction of the push rod 5 is parallel to the axial direction of the rotating shaft of the handrail 1. The detection position of the position sensor 6 is any position above half the height of the end of the handrail 1 when it is fully open.

[0026] In specific implementation, the consistency fixture for detecting the opening of the double-opening handrail also includes a closing cylinder 9, a connecting plate 11 connected to the output end of the closing cylinder 9, and a roller 12 axially connected to the connecting plate 11; when the output rod of the closing cylinder 9 is pushed out, the roller 12 can press the handrail 1 to the closed state.

[0027] In specific implementation, the consistency fixture for detecting the opening of the double-opening handrail further includes a base bracket 8 disposed on the base 0, and the handrail 1 is limited to the base bracket 8. The handrail 1 is detachably fixed to the base bracket 8 by fasteners, or the base bracket 8 is provided with a limiting groove, and the bottom protrusion of the handrail 1 matches the limiting groove.

[0028] The electrical connection between the timer 7, the opening cylinder 3, and the position sensor 6 involved in this utility model is achieved, for example, through conventional wires or a standard industrial bus (such as the I / O module of a PLC) to transmit signals and synchronously trigger timing and status detection. This connection method is common knowledge in the field of industrial automation control and is widely seen in existing equipment (such as the electrical connection between the push rod module and the sensor in CN214844037U). Its communication logic, such as signal acquisition and timing matching, is based on mature technical solutions (such as the standard interface protocol of microprocessors or programmable controllers). Therefore, it is not the core innovation of the utility model, but merely an application of existing technical means to achieve functional integration.

[0029] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
