Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a safety switch action distance detection fixture for a pulsator washing machine. Background Art

[0002] When a pulsator washing machine is dehydrating, the spin drum rotates at high speed. At this time, if the cover is opened, there will be certain safety risks. If the spin drum is subjected to unbalanced force, it will produce abnormal vibrations and collide with the cabinet. This will not only make unpleasant noises, but may also cause mechanical failures or cause the washing machine to shift.

[0003] At present, in order to avoid this situation, a safety switch is usually set on the cabinet of the pulsator washing machine for detection. When the cover is opened to a certain angle, the safety switch generates a corresponding signal to stop the dehydration action. When the dehydration drum is subjected to unbalanced force, the dehydration drum hits the cabinet and hits the safety switch at the same time, thereby triggering the safety switch to generate a corresponding signal to stop the dehydration action, thereby providing safety protection for the pulsator washing machine.

[0004] For example, the washing machine disclosed in the prior art CN1254578C comprises: a washing machine body; an upper box body disposed on the upper part of the body and having an opening; a cover mounted on the upper box body through a mounting portion of the upper box body and covering the opening; a safety switch placed in the upper box body and connected and disconnected in conjunction with the opening and closing of the cover; a switch operating portion extending rearwardly from the rear wall of the cover; a cover opening and closing detection rod disposed on the safety switch; a linkage component that links the cover opening and closing detection rod and the switch operating portion, wherein the above-mentioned box body has a The upper box body is extended to have a first rib with a groove on the upper part, the first end of the linkage member is clamped on the cover opening and closing detection rod, and the second end of the linkage member is formed by bending at a substantially right angle at the first bending portion to form a hook portion. When the cover is opened, the hook portion is embedded in the groove and the cover opening and closing detection rod is lowered, thereby disconnecting the safety switch. When the cover is closed, the hook portion is hooked on the switch operating part and is pulled upward while the trajectory is restricted by the groove, so that the cover opening and closing detection rod is lifted and the safety switch is turned on.

[0005] However, in the actual inspection process of the pulsator washing machine, a safety switch is usually placed on the washing machine to detect whether a corresponding signal is generated when the safety switch moves to a preset distance, to detect whether the action distance of the safety switch meets the requirements, thereby detecting whether the safety switch is qualified. However, this detection method is inefficient and the detection result is inaccurate, which can easily cause the safety switch to fail. When the machine cover is opened or the spin drum vibrates abnormally, the pulsator washing machine cannot be shut down in time, which poses a great safety hazard and can easily cause mechanical failure of the pulsator washing machine, affecting its service life. Utility Model Content

[0006] The purpose of the utility model is to provide a safety switch action distance detection fixture for a pulsator washing machine, so as to solve the problem of low efficiency in detecting whether the safety switch action distance is qualified in the prior art, and to improve the detection efficiency and detection accuracy of whether the safety switch is qualified.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a safety switch action distance detection fixture for a pulsator washing machine, comprising a base, a mounting platform, a cover opening and closing detection component and an abnormal vibration detection component, the safety switch comprising a cover opening and closing detection rod for detecting the opening and closing of the upper cover and a swing rod for detecting the swing amplitude of the inner drum of the pulsator washing machine, the mounting platform is fixed above the base and used to fix the safety switch to be detected, so that the cover opening and closing detection rod faces the cover opening and closing detection component and the swing rod is suspended downwardly below the mounting platform, the cover opening and closing detection component is slidably connected to the top of the mounting platform and supports the cover opening and closing detection rod upward to simulate the open cover state of the pulsator washing machine, the abnormal vibration detection component is arranged below the mounting platform and can move relative to the mounting platform, and the abnormal vibration detection component acts on the swing rod to simulate the swing condition of the inner drum of the pulsator washing machine.

[0008] After adopting the above technical scheme, the utility model has the following advantages: through the safety switch action distance detection fixture, the cover opening state and the inner drum deflection of the pulsator washing machine can be simulated, so as to accurately detect the action distance of the safety switch, and it is easy to judge whether the action distance of the safety switch to be detected is qualified, improve the sensitivity and reliability of the safety switch, effectively reduce safety hazards, and ensure that the safety switch can be activated in time when the cover is opened or the inner drum is abnormally deflected, so that the pulsator washing machine can be shut down in time. The detection stroke of the cover opening and closing detection component and the abnormal vibration detection component is fixed, which ensures that the detection results are more accurate. In addition, the detection operation of the safety switch action distance detection fixture is simple and easy to use. The safety switch only needs to be installed once to realize two tests. There is no need to place the safety switch in the pulsator washing machine for detection. It is easier to get the test results, which is conducive to improving the detection efficiency.

[0009] Furthermore, the cover opening and closing detection assembly includes a detection platform slidably connected to the mounting platform, the detection platform is used to support the cover opening and closing detection rod upward to simulate the open state of the upper cover, and the detection platform slides relative to the mounting platform to adjust the distance between the detection platform and the cover opening and closing detection rod. By adopting the above-mentioned technical scheme, by adjusting the distance between the detection platform and the cover opening and closing detection rod, adjusting the upward lifting angle of the cover opening and closing detection rod to simulate the open state of the pulsator washing machine, the accurate detection of the action distance of the safety switch can be achieved. The detection platform can be slid and adjusted, and the operation is simple, which makes the detection process of the safety switch simpler and faster, which is conducive to improving the detection efficiency and saving the detection time. The detection platform slides relative to the mounting platform to adjust the distance between the detection platform and the cover opening and closing detection rod. The detection stroke is relatively fixed, which ensures that the detection accuracy is more accurate. It can also be used to detect whether the action distance of the safety switch of different models of pulsator washing machines is qualified, thereby improving the flexibility and applicability of the detection.

[0010] Furthermore, the height difference of adjacent detection surfaces is no more than 2mm. The above technical solution can more accurately simulate different opening states of the pulsator washing machine, which helps to improve the accuracy of the detection results and the detection precision; if the height difference of adjacent detection surfaces is greater than 2mm, the height difference is too large, which reduces the accuracy of the safety switch action distance of the pulsator washing machine in different opening states, and the detection result is unreliable, resulting in the pulsator washing machine not being able to stop in time when the cover is opened to the preset angle, which poses a greater safety hazard.

[0011] Furthermore, the detection table is provided with a plurality of detection surfaces at different heights at one end facing the cover opening and closing detection rod, and the cover opening and closing detection rod is placed on the detection surfaces at different heights to simulate the opening state of the upper cover at different angles. By adopting the above technical solution, by setting a plurality of detection surfaces at different heights, the action distance of the cover opening and closing detection rod at different angles can be detected, and the opening state of the pulsator washing machine can be more comprehensively simulated, thereby more accurately detecting the sensitivity and reliability of the safety switch in different opening states.

[0012] Furthermore, the cover opening and closing detection component includes a sliding member fixed on the mounting platform, the sliding member is located on both sides of the mounting platform, a sliding groove is provided on the inner side surface of the sliding member, and the two sides of the detection platform are inserted into the sliding groove for cooperation; or, the cover opening and closing detection component includes a sliding member fixed on the mounting platform, the sliding member is located on both sides of the mounting platform, the sliding member is provided with a slide rail, and the two sides of the detection platform are connected to the slide rail. By adopting the above-mentioned technical solution, by connecting the detection platform with the slide groove or the slide rail, the sliding of the detection platform is guided, the detection platform can be easily slid to adjust the distance between the detection platform and the cover opening and closing detection rod, and the distance between the detection platform and the cover opening and closing detection rod can be more accurately controlled, which can improve the stability of the simulated cover opening state and make the detection result more reliable.

[0013] Furthermore, the mounting table is provided with a mounting groove for accommodating the safety switch to be tested, and positioning columns are provided on both sides of the mounting groove. The positioning columns are inserted into the lugs of the safety switch, and there is a gap between the positioning columns and the side walls of the mounting groove to accommodate the lugs. The side walls of the mounting groove fit with the outer side of the lugs. With the aforementioned technical solution, the positioning columns are inserted into the lugs of the safety switch to stably fix the safety switch in the mounting groove, ensuring that the safety switch does not shake in the mounting groove, thereby ensuring the accuracy of detection. The side walls of the mounting groove fit with the outer side of the lugs, further ensuring that the safety switch is stably and reliably installed in the mounting groove. The gap between the positioning columns and the side walls of the mounting groove is used to accommodate the lugs, and also provides a limit and guide for the installation of the safety switch. The safety switch can be reliably fixed by simply placing the lugs of the safety switch into the mounting groove, without the need for other clamping operations, which facilitates convenient and quick fixing of the safety switch.

[0014] Furthermore, the base and the mounting platform are connected via a vertical plate, and the abnormal vibration detection assembly includes a striker rod, which is movably connected to the vertical plate and movably pushes the swing rod relative to the vertical plate to simulate the deflection of the inner drum of the pulsator washing machine. By adopting the above technical solution, the deflection caused by the imbalance of the inner drum of the pulsator washing machine can be simulated by pushing the swing rod with the striker rod. When the striker rod pushes the swing rod to swing to a preset amplitude, whether the safety switch is qualified can be judged by whether the safety switch is actuated. The action distance of the swing rod under abnormal vibration can also be more accurately detected. The detection result is more accurate and reliable, the detection method is simple, easy to operate, and conducive to improving the detection efficiency.

[0015] Furthermore, two parallel vertical plates are vertically fixed on the base, and the impact rod passes through the two vertical plates. One end of the impact rod is the impact end of the push-up swing rod, and the other end is the hand-held end, and the hand-held end is provided with a handle. With the aforementioned technical solution, the hand-held end is convenient for the tester to hold and perform the impact action. Pushing the impact rod forward causes the impact end to push the swing rod to trigger the action of the safety switch, which makes the operation more convenient and helps to improve the detection efficiency. The impact rod passes through the two vertical plates, so that the impact rod is movably connected to the vertical plates, which can not only limit the impact rod and ensure the movement stability of the impact rod, but also provide a push-up guide for the impact rod, ensuring the accuracy of the movement trajectory of the impact rod, so that the impact rod can only move along a fixed trajectory, ensuring the detection accuracy.

[0016] Furthermore, the abnormal vibration detection component includes a guide rod, which is fixed between the two vertical plates and parallel to the impact rod, and a guide slider is fixed on the impact rod, and the guide slider is slidably connected to the guide rod. With the above technical solution, the guide slider cooperates with the guide rod to provide guidance and positioning for the impact rod, and the guide slider slides along the guide rod to ensure that the impact rod will not deviate or shake during the movement, thereby triggering the safety switch action more accurately and improving the detection accuracy. At the same time, the guide slider can also position the impact rod to ensure that the impact rod performs the impact action along the same trajectory, thereby improving the accuracy of the simulation.

[0017] Furthermore, the guide slider can adjust its position relative to the impact rod, and the distance between the guide slider and the vertical plate near the impact end of the impact rod is the detection stroke of the impact rod. By adopting the above-mentioned technical solution, the handheld end is pushed to make the impact end push the swing rod, and the guide slider moves from the set position to the vertical plate near the impact end of the impact rod. The movement distance of the guide slider is the detection stroke of the impact rod, and the action distance of the swing rod of the safety switch to be tested can be obtained. Moreover, only one detection fixture is needed to accurately detect different types of safety switches, thereby improving the flexibility and use efficiency of the equipment.

[0026] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0027] like Figures 1 to 5 As shown, the utility model provides a safety switch action distance detection fixture for a pulsator washing machine, comprising a base 1, a mounting platform 2, a cover opening and closing detection component and an abnormal vibration detection component, the safety switch 3 comprises a cover opening and closing detection rod 31 for detecting the opening and closing of the upper cover and a swing rod 32 for detecting the swing amplitude of the inner drum of the pulsator washing machine, the mounting platform 2 is fixed above the base 1 and is used to fix the safety switch 3 to be detected, so that the cover opening and closing detection rod 31 faces the cover opening and closing detection component, and the swing rod 32 is suspended downwardly below the mounting platform 2, the cover opening and closing detection component is slidably connected to the top of the mounting platform 2 and supports the cover opening and closing detection rod 31 upward to simulate the open cover state of the pulsator washing machine, the abnormal vibration detection component is arranged below the mounting platform 2 and can move relative to the mounting platform 2, and the abnormal vibration detection component acts on the swing rod 32 to simulate the swing condition of the inner drum of the pulsator washing machine.

[0028] In this embodiment, the detection strokes of the cover opening and closing detection component and the abnormal vibration detection component are fixed to ensure that the detection results are more accurate. The cover opening and closing detection component is slidably connected to the top of the mounting platform 2, and supports the cover opening and closing detection rod 31 upward to simulate the open state of the pulsator washing machine. The sliding cover opening and closing detection component can adjust the distance between the sliding cover opening and closing detection component and the cover opening and closing detection rod 31, thereby adjusting the upward lifting angle of the cover opening and closing detection rod 31. In the process of simulating the opening of the upper cover, the sliding cover opening and closing detection component moves away from the cover opening and closing detection rod 31, so that the cover opening and closing detection rod 31 gradually decreases. When the upward lifting angle of the cover opening and closing detection rod 31 gradually decreases to a certain angle, the safety switch 3 is actuated. Therefore, it is easy to judge whether the action distance of the cover opening and closing detection rod 31 of the safety switch 3 to be detected meets the requirements, and the action distance of the cover opening and closing detection rod 31 of the safety switch 3 to be detected can be obtained. The abnormal vibration of the inner drum of the pulsator washing machine hits the swing rod 32, and the swing rod 32 swings relatively greatly accordingly, so that the safety switch 3 is actuated. The abnormal vibration detection component acts on the swing rod 32, so that the swing rod 32 swings relatively greatly to trigger the safety switch 3. When the swing amplitude of the swing rod 32 reaches a certain amplitude, the safety switch 3 is actuated, and it can be judged whether the action distance of the swing rod 32 of the safety switch 3 to be detected meets the requirements, and the action distance of the swing rod 32 is obtained. Through the safety switch action distance detection fixture, it is easy to judge whether the action distance of the safety switch 3 to be detected is qualified, and the cover opening state and the inner drum deflection of the pulsator washing machine can be simulated, so as to accurately detect the action distance of the safety switch 3, improve the sensitivity and reliability of the safety switch 3, effectively reduce safety hazards, and ensure that the safety switch 3 can be actuated in time when the cover is opened or the inner drum is abnormal, so that the pulsator washing machine can be stopped in time. In addition, the detection operation of the safety switch action distance detection fixture is simple and easy to use. There is no need to place the safety switch 3 in the pulsator washing machine for detection, and the detection result can be obtained more easily, which is conducive to improving the detection efficiency.

[0029] In order to adjust the distance between the cover opening and closing detection assembly and the cover opening and closing detection rod 31, in one embodiment, the cover opening and closing detection assembly includes a detection platform 41 slidably connected to the mounting platform 2, the detection platform 41 is used to support the cover opening and closing detection rod 31 upward to simulate the opening state of the upper cover, and the detection platform 41 slides relative to the mounting platform 2 to adjust the distance between the detection platform 41 and the cover opening and closing detection rod 31. By adjusting the distance between the detection platform 41 and the cover opening and closing detection rod 31, adjusting the upward lifting angle of the cover opening and closing detection rod 31 to simulate the opening state of the pulsator washing machine, the accurate detection of the action distance of the safety switch 3 can be achieved. The detection platform 41 can be slidably adjusted, and the operation is simple, so that the detection process of the safety switch 3 is simpler and faster, which is conducive to improving the detection efficiency and saving the detection time. It can also be used to detect whether the action distance of the safety switch 3 of different models of pulsator washing machines is qualified, and improve the flexibility and applicability of the detection.

[0030] like Figure 5 As shown, in order to improve the detection accuracy, a plurality of detection surfaces 411 at different heights are provided on the detection platform 41 at one end facing the cover opening and closing detection rod 31, and the cover opening and closing detection rod 31 is placed on the detection surfaces 411 at different heights to simulate the opening state of the upper cover at different angles. By providing a plurality of detection surfaces 411 at different heights, the movement distance of the cover opening and closing detection rod 31 at different angles can be detected, and the opening state of the pulsator washing machine can be more comprehensively simulated, thereby more accurately detecting the sensitivity and reliability of the safety switch 3 in different opening states.

[0031] Among them, the height difference H of adjacent detection surfaces 411 is not greater than 2mm, and the height difference H of adjacent detection surfaces 411 can be designed to be 0.5mm, 1mm, 1.5mm or 2mm, etc., which can more accurately simulate the different opening states of the pulsator washing machine, help to improve the accuracy of the detection results, and improve the detection accuracy; if the height difference H of adjacent detection surfaces 411 is greater than 2mm, the height difference H is too large, which reduces the accuracy of the action distance of the safety switch 3 of the simulated pulsator washing machine in different opening states, and the detection result is unreliable, resulting in the pulsator washing machine cannot be stopped in time when the cover is opened to the preset angle, which poses a great safety hazard.

[0032] In order to make the detection platform 41 slidably connected to the mounting platform 2, in one embodiment, the cover opening and closing detection assembly includes a sliding member 42 fixed on the mounting platform 2, the sliding member 42 is located on both sides of the mounting platform 2, and the inner side of the sliding member 42 is provided with a sliding groove, and the two sides of the detection platform 41 are inserted into the sliding groove for matching; in another embodiment, the cover opening and closing detection assembly includes a sliding member 42 fixed on the mounting platform 2, the sliding member 42 is located on both sides of the mounting platform 2, and the sliding member 42 is provided with a slide rail, and the two sides of the detection platform 41 are connected to the slide rail. By inserting the two sides of the detection platform 41 into the slide groove for matching or connecting with the slide rail, the detection platform 41 can be easily slid to adjust the distance between the detection platform 41 and the cover opening and closing detection rod 31, and the distance between the detection platform 41 and the cover opening and closing detection rod 31 can be more accurately controlled, so that the stability of the simulated cover opening state can be improved, and the detection result is more reliable.

[0033] In order to stably fix the safety switch 3 to be tested on the mounting platform 2, in one embodiment, a mounting groove 21 for accommodating the safety switch 3 to be tested is provided on the mounting platform 2, and positioning columns 22 are provided on both sides of the mounting groove 21. The positioning columns 22 are inserted into the lugs 33 of the safety switch 3. There is a gap between the positioning columns 22 and the side walls of the mounting groove 21 for accommodating the lugs 33, and the side walls of the mounting groove 21 are in contact with the outer side surfaces of the lugs 33. The positioning column 22 is inserted into the lug 33 of the safety switch 3 to stably fix the safety switch 3 in the mounting groove 21, ensuring that the safety switch 3 does not shake in the mounting groove 21, thereby ensuring the detection accuracy. The side wall of the mounting groove 21 fits with the outer side of the lug 33, further ensuring that the safety switch 3 is stably and reliably installed in the mounting groove 21. The gap between the positioning column 22 and the side wall of the mounting groove 21 is used to accommodate the lug 33, and also provides a limit and guide for the installation of the safety switch 3. The safety switch 3 can be reliably fixed by simply placing the lug 33 of the safety switch 3 in the mounting groove 21, without the need for other clamping operations, so that the safety switch 3 can be fixed conveniently and quickly.

[0034] In order to realize that the abnormal vibration detection component acts on the swing rod 32 to simulate the deflection of the inner drum of the pulsator washing machine, in one embodiment, the base 1 and the mounting platform 2 are connected by the vertical plate 5, and the abnormal vibration detection component includes a striker rod 61, which is movably connected to the vertical plate 5 and pushes the swing rod 32 relative to the vertical plate 5 to simulate the deflection of the inner drum of the pulsator washing machine. By pushing the swing rod 32 by the striker rod 61, the deflection caused by the imbalance of the inner drum of the pulsator washing machine can be simulated. When the striker rod 61 pushes the swing rod 32 to swing to a preset amplitude, the safety switch 3 is judged to be qualified by whether it is actuated. The action distance of the swing rod 32 under abnormal vibration can also be more accurately detected. The detection result is more accurate and reliable, and the detection method is simple and easy to operate, which is conducive to improving the detection efficiency.

[0035] In order to facilitate the control of the impact stroke of the impact rod 61, two parallel vertical plates 5 are vertically fixed on the base 1. The impact rod 61 passes through the two vertical plates 5. One end of the impact rod 61 is the impact end 611 that pushes the top swing rod 32, and the other end is the hand-held end. The hand-held end is provided with a handle 612. The handle 612 is convenient for the tester to hold the impact action. Pushing the impact rod 61 forward causes the impact end 611 to push the top swing rod 32 to trigger the action of the safety switch 3. The operation is more convenient and is conducive to improving the detection efficiency. The impact rod 61 passes through the two vertical plates 5, so that the impact rod 61 is movably connected to the vertical plates 5, which can not only limit the impact rod 61 to ensure the movement stability of the impact rod 61, but also provide a push-up guide for the impact rod 61, ensuring the accuracy of the movement trajectory of the impact rod 61, so that the impact rod 61 can only move along a fixed trajectory to ensure the detection accuracy.

[0036] In order to further ensure the stability of the impact rod 61, the abnormal vibration detection assembly includes a guide rod 62, which is fixed between the two vertical plates 5 and parallel to the impact rod 61. A guide slider 613 is fixed on the impact rod 61, and the guide slider 613 is slidably connected to the guide rod 62. The guide slider 613 cooperates with the guide rod 62 to provide guidance and positioning for the impact rod 61. The guide slider 613 slides along the guide rod 62 to ensure that the impact rod 61 will not deviate or shake during the movement, thereby more accurately triggering the action of the safety switch 3 and improving the detection accuracy. At the same time, the guide slider 613 can also position the impact rod 61 to ensure that the impact rod 61 performs the impact action along the same trajectory, thereby improving the accuracy of the simulation.

[0037] In order to fix the guide slider 613 on the impact rod 61, in one embodiment, the guide slider 613 is a U-shaped structure, the impact rod 61 and the guide rod 62 are arranged on the inner side of the U-shaped structure, and a fastening bolt is arranged on the outer side of the U-shaped structure. The fastening bolt 614 is located on one side of the impact rod 61. By tightening the fastening bolt 614, the guide slider 613 can be fixed on the impact rod 61. The fixing method is simple and convenient for adjusting the position of the guide slider 613.

[0038] In order to obtain the detection stroke D of the impact rod 61, the guide slider 613 can be adjusted relative to the impact rod 61, and the distance between the guide slider 613 and the vertical plate 5 close to the impact end 611 of the impact rod 61 is the detection stroke D of the impact rod 61. Push the handheld end to make the impact end 611 push the swing rod 32, and the guide slider 613 moves from the set position to the vertical plate 5 close to the impact end 611 of the impact rod 61. The movement distance of the guide slider 613 is the detection stroke D of the impact rod 61, and the action distance of the swing rod 32 of the safety switch 3 to be detected can be obtained. And only one detection fixture is needed to accurately detect different types of safety switches 3, which improves the flexibility and use efficiency of the equipment.

[0039] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
