[0032] Example 1:
[0033] like Figures 1-5As shown, the present invention provides a feeler gauge assembly 1, comprising: a feeler gauge body, a force measuring device, and a laser device. The feeler gauge body includes a measuring scale and a handle 12, which are connected to each other in the length direction. The force measuring device is connected to the handle 12 and has a pushing part adapted to move in the length direction. The pushing part is adapted to cooperate with and be pushed by the object to be measured when the measuring scale is inserted into the gap. The force measuring device is adapted to determine the force required for the measuring scale to be inserted into the gap based on the moving distance of the pushing part. The laser device is connected to the handle 12 and is adapted to emit a laser beam to the object to be measured. The laser device is adapted to determine the distance of the gap based on the distance of the laser beam and the measuring scale.
[0034] In some embodiments, the feeler gauge body includes a measuring scale and a handle 12, which are connected to each other in the longitudinal direction so that a user can hold the handle 12 and insert the measuring scale into the gap to be measured. A force measuring device is connected to the handle 12 and is equipped with a pusher that can move in the longitudinal direction. When the measuring scale is inserted into the gap, the pusher contacts the object to be measured and moves as the measuring scale goes deeper. The force measuring device can calculate the force required to insert the measuring scale into the gap based on the displacement of the pusher. A laser device is also connected to the handle 12 and can emit a laser beam to the surface of the object to be measured. By analyzing the distance of the laser beam and combining it with the data of the measuring scale, the distance of the gap can be accurately determined.
[0035] It is understood that the feeler gauge assembly 1 of this application can be used for safety measurement of elevator doors. When measuring the safety of elevator doors, it is necessary to measure the closure degree of elevator door 2. At this time, a pushing or pulling force needs to be applied to elevator door 2 to make elevator door 2 tend to open or even open elevator door 2 (in actual work, a force of 150N needs to be applied to elevator door 2, and then the gap formed between elevator door 2 is measured through the feeler gauge body).
[0036] When the feeler gauge assembly 1 of this application is working, the measuring gauge is first inserted into the gap between the elevator doors 2 and continues to go deeper. During the process of the measuring gauge going deeper, the value of the force measuring device is read. When the value of the force measuring device reaches 150N, the data of the laser device is observed. The data of the laser device is the gap between the elevator doors when a force of 150N is applied to the elevator doors 2.
[0037] In some embodiments, the laser device is equipped with a first display screen 31 located on the outer peripheral wall of the handle 12. The first display screen 31 can display the distance dimension of the gap, thereby facilitating user reading and improving the ease of use of the feeler gauge assembly 1.
[0038] According to the feeler gauge assembly 1 of the present invention, compared with carrying both feeler gauge and force gauge at the same time during work, carrying the feeler gauge assembly 1 of the present application can reduce the tools required during work, improve the convenience of work. At the same time, the feeler gauge assembly 1 of the present application has a simple working principle and is easy to operate, which can improve the work efficiency for measuring the gap of elevator door 2, thereby shortening the working time required to measure the gap of elevator door 2. Moreover, a single person can complete the safety measurement of elevator door 2 using the feeler gauge assembly 1 of the present application, reducing labor costs.
[0039] Example 2:
[0040] Based on Embodiment 1, the force measuring device in this embodiment includes: a housing 21, a force measuring spring 22, a push rod 23, and a push plate 24. The housing 21 is connected to the handle 12. The force measuring spring 22 is disposed inside the housing 21 and one end is connected to the housing 21. One end of the push rod 23 is movably disposed inside the housing 21 and connected to the other end of the force measuring spring 22. The push plate 24 is located outside the housing 21 and connected to the other end of the push rod 23.
[0041] In some embodiments, when a user uses the feeler gauge assembly 1 for measurement, the push plate 24 first contacts the object to be measured and receives a reaction force as the measuring gauge is inserted into the gap. This reaction force is transmitted to the push rod 23 through the push plate 24, causing the push rod 23 to move within the housing 21 and compress or stretch the force-measuring spring 22. The deformation of the force-measuring spring 22 reflects the magnitude of the force applied to it. Preferably, the force-measuring device is also equipped with a digital display device, which includes a second display screen 25 and a displacement sensor, etc. The displacement sensor can acquire the deformation of the force-measuring spring 22, and then the second display screen 25 can display the force value through the deformation, thereby facilitating the ease of use of the feeler gauge assembly 1 of this application.
[0042] It is understandable that this application utilizes the characteristics of the force-measuring spring 22 to accurately measure the force encountered during insertion, providing additional data support in addition to the gap size. Moreover, the addition of the force-measuring function makes the feeler gauge assembly 1 not only limited to size measurement, but also applicable to application scenarios that require evaluation of insertion force, such as quality inspection, mechanical assembly and other fields.
[0043] According to some embodiments of the present invention, a movable channel extending in the length direction is provided in the handle 12, and an open opening communicating with the movable channel is provided at one end of the handle 12 facing the measuring scale. The measuring scale includes: a wedge measuring scale 111, a rotating rod 112 and a moving rod 113. One end of the rotating rod 112 is fixedly connected to one end of the wedge measuring scale 111 in the length direction. The moving rod 113 is movably disposed in the movable channel and located at one end of the rotating rod 112 away from the wedge measuring scale 111. The other end of the rotating rod 112 is rotatably and movably engaged with the moving rod 113. The moving rod 113 rotates to drive the rotating rod 112 to move and rotate in the movable channel.
[0044] In related technologies, elevators are equipped with elevator doors 2, which can be single-door or double-door. For single-door elevators, when elevator door 2 is closed, it contacts the door frame 3, forming an angle (usually 90°) between them. In this case, for traditional digital feeler gauges (which include a measuring scale and a sliding rod), the sliding rod can interfere with the insertion of the measuring scale, thus preventing the traditional digital feeler gauge from performing safety measurements on single-door elevators or resulting in inaccurate measurements.
[0045] In the feeler gauge assembly 1 of this application, the wedge measuring scale 111 is a component that is directly inserted into the gap. The two sides of the wedge measuring scale 111 in the width direction are a straight side and an inclined side, respectively (for traditional digital feeler gauges, the straight side is close to the slide bar, which causes the slide bar to affect the contact between the straight side and the door frame, thus making it impossible to measure the safety of a single-door elevator). When measuring the safety of a single-door elevator, the user can move the moving rod 113 to move and rotate the rotating rod 112 in the movable channel, thereby driving the wedge measuring scale 111 to rotate relative to the handle 12 to adjust the orientation of the straight side of the wedge measuring scale 111. Then, the user can make the straight side of the wedge measuring scale 111 contact the door frame 3 (the side surface of the door frame 3 that forms an angle with the elevator door 2), and the push plate 24 contact the elevator door 2. At this time, the user pushes the wedge measuring teeth 111 to insert into the gap to measure the safety of the elevator door 2.
[0046] It should be noted that during the above measurement process, the contact between the flat side and the door frame 3 ensures that the wedge measuring ruler 111 is inserted into the gap at the correct angle, thereby ensuring the accuracy of the gap measurement. At the same time, the contact between the push plate 24 and the elevator door 2 assists the wedge measuring ruler 111 in being inserted into the gap at a stable angle (the flat side of the wedge measuring ruler 111 is in contact with the door frame 3, and the push plate 24 is in contact with the elevator door 2. Thus, during the measurement, both sides of the wedge measuring ruler 111 in the radial direction can be stabilized, making the movement of the wedge measuring ruler 111 more stable when it is inserted, and avoiding the insertion angle deviation from affecting the measurement result).
[0047] Of course, since the flat side of the wedge measuring ruler 111 is in contact with the door frame 3, the door frame 3 can limit the wedge measuring ruler 111, so that the feeler gauge assembly 1 can stably cooperate with the elevator door 2, thereby assisting the push plate 24 to stably cooperate with the elevator door 2. In turn, when the wedge measuring ruler 111 is inserted into the gap, the push plate 24 can stably drive the force measuring spring 22 to deform through the push rod 23, so as to improve the measurement accuracy of the force value.
[0048] Therefore, through the cooperation between the straight side of the wedge measuring ruler 111 and the door frame 3, and the cooperation between the push plate 24 and the elevator door 2, the push plate 24 and the wedge measuring ruler 111 can assist each other, thereby improving their stability during operation, and thus improving the accuracy of force measurement and gap measurement, and improving the measurement accuracy of the feeler gauge assembly 1.
[0049] Example 3:
[0050] Based on Embodiment 2, this embodiment features multiple limiting blocks spaced circumferentially and protruding radially on the inner peripheral wall of the movable channel. A slide rail is defined between any two adjacent limiting blocks. Each limiting block has a first helical tooth at its end facing the rotating rod 112. Multiple moving blocks 1121 are spaced circumferentially on the outer peripheral wall of the rotating rod 112 facing the moving rod 113. Each moving block 1121 has a second helical tooth 1122 at its end facing the rotating rod 112. The moving rod 113 is adapted to move within the movable channel to selectively engage the first and second helical teeth 1122 axially (parallel to the length direction), or to movably accommodate the moving blocks 1121 within the slide rail. Notably, the outer peripheral wall of the moving rod 113 has multiple mating blocks extending in the length direction, which are movably accommodated within the slide rail, thereby ensuring stable movement of the moving rod 113 in the length direction.
[0051] In some embodiments, a plurality of circumferentially spaced and radially protruding limiting blocks are provided on the inner peripheral wall of the active channel. The plurality of limiting blocks can enhance the structural strength of the handle 12. A slide is also formed between any two adjacent limiting blocks. The inner peripheral wall of the slide can restrict the outer peripheral wall of the moving block 1121, thereby allowing the moving block 1121 to move stably within the slide (the moving block 1121 is provided on the outer peripheral wall of the rotating rod 112 and extends in the length direction. The outer peripheral wall of the moving block 1121 abuts against the inner peripheral wall of the slide in the circumferential direction, thereby preventing the rotating rod 112 from rotating when the moving block 1121 is located within the slide, thereby preventing the wedge measuring ruler 111 from rotating when no adjustment is needed, ensuring the positional stability of the wedge measuring ruler 111, and thus ensuring the measurement accuracy of the feeler gauge assembly 1).
[0052] Each limiting block has a first helical tooth at one end facing the rotating rod 112. Multiple moving blocks 1121 are arranged on the outer peripheral wall of the end of the rotating rod 112 facing the moving rod 113. These moving blocks 1121 are spaced apart circumferentially, and each moving block 1121 has a second helical tooth 1122 at one end facing the rotating rod 112. When the moving rod 113 drives the rotating rod 112 to move, causing the moving block 1121 of the rotating rod 112 to move outside the slide rail, the first helical tooth and the second helical tooth 1122 abut against each other axially. At this time, the tooth flank of the second helical tooth 1122 can guide (sliding guide) the tooth flank of the first helical tooth, allowing the rotating rod 112 to enter an adjacent slide rail when moving towards the moving rod 113, thereby realizing the angle of the wedge measuring ruler 111.
[0053] According to some embodiments of the present invention, the rotating rod 112 has a first tooth 1123 at one end facing the moving rod 113, and the moving rod 113 has a second tooth 1131 at one end facing the rotating rod 112. The tooth lateral surface of the first tooth 1123 and the tooth lateral surface of the second tooth 1131 are axially slidingly engaged. The moving rod 113 moves axially and has a first position and a second position. When the moving rod 113 moves from the first position to the second position, it pushes the rotating rod 112 toward the wedge-shaped measuring scale 111 until the first helical tooth engages with the second helical tooth 1122. The tooth lateral surface of the first tooth 1123 contacts the tooth lateral surface of the second helical tooth 1122.
[0054] In some embodiments, when the moving rod 113 moves toward the rotating rod 112 while inside the slide, it can drive the rotating rod 112 to move (when inside the slide, the tooth lateral surface of the first tooth 1123 and the tooth lateral surface of the second tooth 1131 abut against each other axially). When the moving block 1121 moves outside the slide, the moving rod 113 continues to move toward the rotating rod 112, which can cause the tooth lateral surface of the first tooth 1123 to slide against the tooth lateral surface of the second tooth 1131 (sliding until the tooth tip of the first tooth 1123 and the tooth of the second tooth 1131 are aligned). The root contact, and during the sliding process, can drive the first tooth 1123 to rotate, thereby realizing the rotation of the rotating rod 112), thereby realizing the rotation of the rotating rod 112 and making the tooth flank of the first helical tooth and the tooth flank of the second helical tooth 1122 axially aligned. Then, the rotating rod 112 moves toward the moving rod 113, which can make the tooth flank of the first helical tooth and the tooth flank of the second helical tooth 1122 abut against each other axially, and under the action of the first helical tooth and the second helical tooth 1122, the moving block 1121 is accommodated in an adjacent slide.
[0055] According to some embodiments of the present invention, the feeler gauge assembly 1 further includes a return spring 13, which is sleeved on the outer periphery of the rotating rod 112, and one end of the return spring 13 cooperates with the handle 12, and the other end of the return spring 13 cooperates with the rotating rod 112.
[0056] Understandably, when the moving rod 113 moves toward the rotating rod 112 and causes the rotating rod 112 to move, the movement of the rotating rod 112 will compress the return spring 13. When the moving block 1121 moves outside the slide and the tooth flanks of the first helical tooth and the tooth flanks of the second helical tooth 1122 are axially aligned, the return force of the return spring 13 can first drive the tooth flanks of the first helical tooth and the tooth flanks of the second helical tooth 1122 to stop axially. Then, the return force of the return spring 13 can continue to drive the rotating rod 112 to move toward the moving rod 113 (the tooth flanks of the first helical tooth and the tooth flanks of the second helical tooth 1122 cooperate with each other for guidance, so that the rotating rod 112 can be driven to rotate and move under the return force of the return spring 13), thereby allowing the moving block 1121 to be accommodated in an adjacent slide.
[0057] Therefore, this application can achieve the following through the above-mentioned settings: moving the moving rod 113 once will cause the rotating rod 112 to rotate by a certain angle, thereby causing the wedge measuring ruler 111 to rotate by an angle, making the angle adjustment of the wedge measuring ruler 111 more convenient and improving the ease of use of the feeler gauge assembly 1.
[0058] Example 4:
[0059] Based on Embodiment 3, the feeler gauge assembly 1 further includes a locking member, which is movably connected to the handle 12. The handle 12 is provided with a moving groove 121 that extends in the length direction and communicates the movable channel with the outside. The locking member is provided with a locking part, which is adapted to move in the radial direction to selectively engage the moving rod 113 with the push rod 23. The push rod 23 moves to drive the moving rod 113 to move in the length direction through the locking part.
[0060] In some embodiments, the locking member is movably connected to the handle 12. The movement of the locking member can cause the locking part to move radially. One end of the locking part in the radial direction engages with the moving rod 113, and when the locking part moves, its other end can optionally engage with the push rod 23.
[0061] When the other end of the locking part is not engaged with the push rod 23, the movement of the push rod 23 can achieve normal force measurement, and at this time, the feeler gauge assembly 1 is in working condition. When the other end of the locking part is engaged with the push rod 23, the movement of the push rod 23 can drive the moving rod 113 to move through the locking part. The movement of the moving rod 113 can drive the wedge measuring scale 111 to rotate, thereby realizing that the angle of the wedge measuring scale 111 can be adjusted by moving the push rod 23. At this time, the feeler gauge assembly 1 is in adjustment condition.
[0062] According to some embodiments of the present invention, the locking element includes: a toggle block 41 and a locking block 42, the toggle block 41 being connected to the handle 12, the locking block 42 extending radially, one end of the locking block 42 engaging with a moving rod 113, the toggle block 41 moving radially to drive the other end of the locking block 42 optionally engaging with a push rod 23 so that the movement of the push rod 23 can drive the moving rod 113 to move via the locking block 42.
[0063] In some embodiments, the actuating block 41 is movably connected to the handle 12. The top of the actuating block 41 protrudes from the handle 12, and the bottom of the actuating block 41 extends into the movable channel and is provided with a slide groove extending in the length direction. A portion of the locking block 42 is located in the movable channel, and another portion of the locking block 42 is located outside the movable channel. The portion of the locking block 42 located in the movable channel is provided with a slider extending in the length direction. The slider is movably received in the slide groove. Thus, the radial movement of the actuating block 41 can drive the locking block 42 to move radially. The other portion of the locking block 42 moves into the housing 21 and cooperates with the push rod 23. At this time, the movement of the push rod 23 can drive the locking block 42 to move in the length direction, and the movement of the push rod 23 in the length direction can drive the moving rod 113 to move in the length direction.
[0064] It is worth mentioning that the housing 21 is connected to the handle 12, and the movable channel inside the handle 12 communicates with the housing 21 through the moving groove 121. The moving groove 121 extends in the length direction, meaning that the inner peripheral wall of the moving groove 121 can restrict part of the outer peripheral wall of the locking block 42, allowing the locking block 42 to move stably in the length direction. This allows the push rod 23 to stably drive the wedge measuring ruler 111 to rotate. Of course, since the inner peripheral wall of the slide groove and the outer peripheral wall of the slider abut in the radial direction, the inner peripheral wall of the slide groove can also restrict the outer peripheral wall of the slider, allowing the slider and the slide groove to slide relative to each other stably and smoothly in the length direction.
[0065] According to some embodiments of the present invention, the push plate 24 is rotatably connected to the push rod 23, the push plate 24 is adapted to rotate relative to the push rod 23 in the axial direction, the projection of the push plate 24 and the wedge measuring ruler 111 in the length direction at least partially overlaps, the push plate 24 is provided with a movable groove that passes through in the length direction, and at least a portion of the wedge measuring ruler 111 is movably disposed in the movable groove.
[0066] In some embodiments, a portion of the wedge measuring ruler 111 is movably housed within a movable groove. Thus, during the insertion of the wedge measuring ruler 111 into the gap, the inner peripheral wall of the movable groove can restrict a portion of the outer peripheral wall of the wedge measuring ruler 111, thereby ensuring stable movement of the wedge measuring ruler 111. Alternatively, the wedge measuring ruler 111 can be disengaged from the movable groove by pulling and rotating the push plate 24. In this case, the user can drive the push rod 23 to rotate by moving the push plate 24.
[0067] It is worth mentioning that the push plate 24 rotates relative to the push rod 23 in the axial direction, which allows the push plate 24 to adapt to more stopping scenarios. This allows the user to rotate the push plate 24 according to different scenarios so that the push plate 24 can stably stop with the object to be measured, thereby ensuring measurement accuracy.
[0068] It should be noted that when no measurement work is being performed, the sharp part of the wedge measuring ruler 111 is housed in the movable groove, which can prevent the feeler gauge assembly 1 from accidentally injuring the staff.
[0069] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
