Description

Technical Field

[0001] This invention belongs to the field of elevator component measuring ruler technology, specifically relating to an elevator door slider engagement depth detection device. Background Technology

[0002] The elevator door slider is detachably installed on the elevator landing door and engages in the sill groove. Its function is to guide the lateral movement of the elevator landing door and hold the bottom of the elevator landing door.

[0003] If the engagement depth between the door slider and the sill groove is insufficient, when the elevator door is impacted by external force, the elevator door will undergo significant deformation, causing the door slider to move upward relative to the sill groove. This can lead to the door slider detaching from the sill, causing the lower retaining device to fail, and resulting in a fall into the shaft accident. Therefore, research on the engagement depth of the elevator door slider (i.e., the depth to which the door slider extends into the sill groove) and its detection technology is particularly necessary.

[0004] Chinese utility model patent (publication number: CN212475727U) discloses an elevator landing door guide shoe engagement depth detector. It is equipped with a long measuring claw that can be inserted into the sill groove, and a main scale body that is perpendicularly connected to the long measuring claw. The sliding horizontal claw on the main scale body is used to locate the top position of the sill groove. The depth of the landing door guide shoe (door slider) inserted into the sill groove, i.e., the engagement depth, can be directly read on the digital display screen on the horizontal measuring claw.

[0005] However, in actual use, after extending the long measuring jaw of the detector into the gap between the bottom of the door slider and the bottom of the sill groove, and then moving the detector upward so that the upper edge of the long measuring jaw directly contacts the door slider, it is still necessary to manually slide the horizontal measuring jaw downward until it contacts the edge of the sill groove, which is inconvenient to use. Summary of the Invention

[0006] The purpose of this invention is to provide an elevator door slider engagement depth detection device to solve the problem of inconvenience caused by structural defects in existing detection devices.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0008] An elevator door slider engagement depth detection device includes:

[0009] A base, on which a connecting rod is vertically mounted, and a measuring ruler is horizontally connected to the bottom of the base;

[0010] A base, which is located above the base and is vertically slidably mounted on the connecting rod, with a vertical rod provided at the end of the base away from the base;

[0011] Mounting base, which is fixedly installed on the free end of the connecting rod and located above the base;

[0012] A lifting frame, which is vertically slidably mounted on a base;

[0013] A first elastic element that causes the base to have an upward tendency to move relative to the base;

[0014] A transmission mechanism is installed between the vertical rod and the lifting frame. The transmission mechanism is rotatably mounted on the mounting base. The transmission mechanism is used to drive the vertical rod to move in the opposite direction to the lifting frame when the lifting frame moves vertically relative to the transmission mechanism.

[0015] A travel indication mechanism for displaying the distance between the upper end face of the measuring scale and the lower end face of the base.

[0016] Further specifying, the transmission mechanism includes a gear, a first rack, and a second rack;

[0017] The gear is located between the first rack and the second rack, and meshes with both the first rack and the second rack simultaneously. The length directions of both the first rack and the second rack are parallel to the length direction of the connecting rod.

[0018] The gear is rotatably mounted on the mounting base;

[0019] The first rack is fixedly installed on the vertical rod;

[0020] The second rack is fixedly installed on the lifting frame.

[0021] This structural design, which uses gears, a first rack, and a second rack to form a transmission mechanism, is compact and highly stable.

[0022] Further specifying, the first elastic element is a first compression spring installed between the base and the pedestal.

[0023] This structural design uses a first compression spring installed between the base and the pedestal as the first elastic element, which makes the pedestal tend to move upward relative to the base. The structure is simple, easy to install, and highly practical.

[0024] Further specifying, the travel indicator mechanism includes a pointer and scale lines;

[0025] The pointer is fixedly mounted on the mounting base;

[0026] The scale lines are set on the lifting frame.

[0027] This structural design uses a pointer fixed on the mounting base and scale lines set on the lifting frame to form a stroke indication mechanism. The relative position between the lifting frame and the mounting base is used to display the relative position between the base and the pedestal, thereby measuring the distance between the upper end face of the measuring scale and the lower end face of the pedestal. This achieves the purpose of displaying the engagement depth between the door slider and the sill groove. The structure is simple and easy to use.

[0028] Further specifying, the lifting frame includes a frame body and a slider;

[0029] The slider is slidably mounted on the frame along the length of the connecting rod, and the scale lines are set on the slider;

[0030] The frame is equipped with a synchronization mechanism that drives the slider to move upward synchronously;

[0031] A connecting block is fixedly provided on the mounting base, and a top block is rotatably mounted on the connecting block. The top block is inclined from top to bottom away from the slider.

[0032] A pressure block is fixedly provided on the top block, and a second elastic element is installed between the pressure block and the connecting block. The second elastic element is used to drive the top block to press against the slider through the pressure block.

[0033] This structural design, through the cooperation of the frame, slider, synchronization mechanism, top block, pressure block and second elastic element, when the lifting frame is pulled upward, the frame drives the slider to overcome the friction between the slider and the top block and move upward synchronously until the base moves downward to contact the top edge of the sill groove.

[0034] At this point, the lifting frame can be moved downwards to make the measuring tape and the base move apart. After releasing the clamp on the door slider, the detection device can be taken out of the sill groove.

[0035] During this process, the top block pushes against the slider, ensuring that the relative position between the slider and the mounting base remains unchanged. This, combined with the pointer fixed on the mounting base, makes it easier to take readings after the detection device is removed from the groove.

[0036] Further specifying, the travel indicator mechanism includes a pointer and scale lines;

[0037] The pointer is fixedly mounted on the base;

[0038] The scale lines are set on the lifting frame.

[0039] This structural design uses a pointer fixedly installed on the base and a scale line set on the lifting frame to form a stroke indication mechanism. The relative position between the lifting frame and the base is used to display the relative position between the base and the base, thereby completing the measurement of the distance between the upper end face of the measuring scale and the lower end face of the base, thus achieving the purpose of displaying the engagement depth between the door slider and the sill groove.

[0040] The lifting frame moves twice the distance of the base relative to the base, which increases the unit size on the scale line. That is, 1mm on the scale line is equivalent to 2mm in actual length, thus reducing the difficulty of observation, improving measurement accuracy, and making it highly practical.

[0041] Further specifying, the lifting frame includes a frame body and a slider;

[0042] The slider is slidably mounted on the frame along the length of the connecting rod, and the scale lines are set on the slider;

[0043] The frame is equipped with a synchronization mechanism that drives the slider to move upward synchronously;

[0044] A connecting block is fixedly provided on the base, and a top block is rotatably installed on the connecting block. The top block is inclined from top to bottom away from the slider.

[0045] A pressure block is fixedly provided on the top block, and a second elastic element is installed between the pressure block and the connecting block. The second elastic element is used to drive the top block to press against the slider through the pressure block.

[0046] This structural design, through the cooperation of the frame, slider, synchronization mechanism, top block, pressure block and second elastic element, when the lifting frame is pulled upward, the frame drives the slider to overcome the friction between the slider and the top block and move upward synchronously until the base moves downward to contact the top edge of the sill groove.

[0047] At this point, the lifting frame can be moved downwards to make the measuring tape and the base move apart. After releasing the clamp on the door slider, the detection device can be taken out of the sill groove.

[0048] During this process, the top block pushes against the slider, ensuring that the relative position between the slider and the base remains unchanged. This, combined with the pointer fixed on the base, makes it easier to take readings after the detection device is removed from the groove.

[0049] Further specified, the synchronization mechanism is a sliding groove formed on the frame, and the slider is slidably mounted in the sliding groove;

[0050] The bottom of the sliding groove forms a support surface for supporting the slider.

[0051] This structural design, through the cooperation of the slider and the sliding groove, not only completes the sliding installation between the slider and the frame, but also forms a support surface for supporting the slider from the bottom of the sliding groove. The structure is simple and highly practical.

[0052] Furthermore, a third elastic element is provided between the frame and the slider to drive the slider to move downward.

[0053] This structural design, through the setting of the third elastic element, allows the pressure block to be pressed after the reading is completed, overcoming the elastic force of the second elastic element. This allows the top block to detach from the slider, and the slider can automatically reset under the action of the third elastic element, making it more convenient to use.

[0054] Furthermore, the lifting frame also includes a crossbar, which is fixedly installed on the frame body and located above the transmission mechanism;

[0055] The free end of the horizontal bar is slidably connected to the vertical bar;

[0056] The crossbar is equipped with a handle, which is located above the transmission mechanism.

[0057] This structural design, through the setting of the crossbar, provides installation space for the handle, making it more convenient to lift the lifting frame upwards;

[0058] At the same time, the crossbars can also provide a second sliding connection between the lifting frame and the base, improving the overall structural stability of the device and making it highly practical.

[0059] The invention employing the above technical solution has the following advantages:

[0060] 1. Through the cooperation of the base, base, mounting base, lifting frame and transmission mechanism, the first elastic element pushes the base to make the base and base open before measurement. Then, using the transmission mechanism, after the measuring scale is inserted into the gap between the bottom of the door slider and the bottom of the sill groove, the lifting frame can be pulled upward to drive the measuring scale of the base to fit against the bottom of the door slider. At the same time, the base moves downward to contact the upper edge of the sill groove. With the help of the stroke indicator mechanism, the distance between the upper end face of the measuring scale and the lower end face of the base is displayed, thereby obtaining the depth of the door slider inserted into the sill groove, that is, the measurement of the engagement depth of the door slider, which is more convenient to use.

[0061] 2. A stroke indication mechanism is formed by a pointer fixedly installed on the base and a scale line set on the lifting frame. The relative position between the lifting frame and the base is used to display the relative position between the base and the base, thereby completing the measurement of the distance between the upper end face of the measuring scale and the lower end face of the base, thus completing the purpose of displaying the engagement depth between the door slider and the sill groove.

[0062] The distance the lifting frame moves relative to the base is twice the distance the base moves relative to the base. This increases the unit size on the scale line, meaning that 1mm on the scale line is equivalent to 2mm in actual length. This reduces the difficulty of observation, improves measurement accuracy, and is highly practical.

[0063] 3. Through the cooperation of the frame, slider, synchronization mechanism, top block, pressure block and second elastic element, during the process of pulling the lifting frame upward, the frame drives the slider to overcome the friction between the slider and the top block and move upward synchronously until the base moves downward to contact the top edge of the sill groove.

[0064] At this point, the lifting frame can be moved downwards to make the measuring tape and the base move apart. After releasing the clamp on the door slider, the detection device can be taken out of the sill groove.

[0065] During this process, the top block pushes against the slider, so that the relative position between the slider and the base does not change. This, combined with the pointer fixed on the base, makes it easier to take the reading after the detection device is removed from the sill groove.

[0066] 4. By setting the third elastic element, after the reading is completed, the pressure block is pressed to overcome the elastic force of the second elastic element, so that after the top block is separated from the slider, the slider can automatically reset under the action of the third elastic element, making it more convenient to use.

[0082] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0083] Example 1:

[0084] like Figures 1-2 As shown, an elevator door slider engagement depth detection device of the present invention includes:

[0085] Base 1, with a connecting rod 11 vertically installed on the base 1, and a measuring ruler 12 horizontally connected to the bottom of the base 1;

[0086] The base 2 is located above the base 1 and is vertically slidably mounted on the connecting rod 11. The end of the base 2 away from the base 1 is vertically provided with a vertical rod. In this embodiment, it is preferred that there are two connecting rods 11, so as to achieve the purpose of vertically sliding the base 2 on the connecting rod 11 and to prevent the base 2 from rotating about the connecting rod 11 as the central axis. Alternatively, a single rod with a polygonal cross-section can be directly selected as the connecting rod 11.

[0087] Mounting base 3 is fixedly installed on the free end of connecting rod 11 and located above base 2;

[0088] Lifting frame 4 is vertically slidably mounted on base 2;

[0089] A first elastic element that gives the base 2 an upward tendency to move relative to the base 1;

[0090] The transmission mechanism is installed between the vertical rod and the lifting frame 4. The transmission mechanism is rotatably mounted on the mounting base 3. The transmission mechanism is used to drive the vertical rod to move in the opposite direction to the lifting frame 4 when the lifting frame 4 moves vertically relative to the transmission mechanism.

[0091] A travel indication mechanism for displaying the distance between the upper end face of the measuring scale 12 and the lower end face of the base 2.

[0092] In this embodiment, before use, the base 1 and the base 2 are in an open state under the pushing action of the first elastic element;

[0093] When in use, place the detection device into the sill groove 102 and fix it to the side of the door slider 101 on the elevator landing door until the base 1 reaches the bottom of the sill groove 102. Then push the detection device horizontally so that the measuring ruler 12 is inserted into the gap between the bottom of the door slider 101 and the bottom of the sill groove 102.

[0094] Pull the lifting frame 4 upwards again, causing the entire detection device to move upwards until the upper surface of the measuring scale 12 is against the bottom of the door slider 101, as shown. Figure 1 As shown;

[0095] Continue pulling the lifting frame 4 to overcome the prestress of the first elastic element, causing the lifting frame 4 to move upward relative to the mounting base 3. Through the transmission mechanism, this simultaneously drives the base 2 downward until the base 2 moves downward and contacts the upper edge of the groove 102. Figure 2 As shown;

[0096] At this point, the distance between the upper end face of the measuring scale 12 and the lower end face of the base 2 can be determined by reading the data on the stroke indicator mechanism, and then the depth of the door slider 101 inserted into the sill groove 102 can be obtained, that is, the engagement depth of the door slider 101.

[0097] After the measurement is completed, move the lifting frame 4 downward a certain distance so that the measuring ruler 12 is no longer attached to the door slider 101 and the base 2 is no longer in contact with the groove edge of the sill groove 102. Then move it laterally so that the measuring ruler 12 is no longer attached to the door slider 101. Finally, pull it upward.

[0098] Example 2:

[0099] like Figures 1-4 As shown, an elevator door slider engagement depth detection device of the present invention includes:

[0100] Base 1, with a connecting rod 11 vertically installed on the base 1, and a measuring ruler 12 horizontally connected to the bottom of the base 1;

[0101] Base 2, which is located above base 1 and is vertically slidably mounted on connecting rod 11, with a vertical rod provided at the end of base 2 away from base 1;

[0102] Mounting base 3 is fixedly installed on the free end of connecting rod 11 and located above base 2;

[0103] Lifting frame 4 is vertically slidably mounted on base 2;

[0104] A first elastic element that gives the base 2 an upward tendency to move relative to the base 1;

[0105] The transmission mechanism is installed between the vertical rod and the lifting frame 4. The transmission mechanism is rotatably mounted on the mounting base 3. The transmission mechanism is used to drive the vertical rod to move in the opposite direction to the lifting frame 4 when the lifting frame 4 moves vertically relative to the transmission mechanism.

[0106] A travel indication mechanism for displaying the distance between the upper end face of the measuring scale 12 and the lower end face of the base 2.

[0107] The transmission mechanism includes a gear 50, a first rack 51, and a second rack 52;

[0108] The gear 50 is located between the first rack 51 and the second rack 52, and meshes with both the first rack 51 and the second rack 52. The length directions of the first rack 51 and the second rack 52 are both parallel to the length direction of the connecting rod 11.

[0109] Gear 50 is rotatably mounted on mounting base 3;

[0110] The first rack 51 is fixedly installed on the vertical rod;

[0111] The second rack 52 is fixedly installed on the lifting frame 4.

[0112] In practice, depending on the actual situation, a rotating rod with grooves at both ends can be selected for rotational mounting on the mounting base. Then, protrusions passing through the grooves can be set on the vertical rod and the lifting frame 4 respectively. The lifting action of the lifting frame 4 is driven by the protrusions on the lifting frame 4 to rotate the rotating rod. Then, by utilizing the cooperation between the protrusions on the vertical rod and the grooves at the other end of the rotating rod, the base 2 is driven to move downwards until it contacts the upper edge of the groove of the sill 102. In this embodiment, the transmission mechanism is formed by the gear 50, the first rack 51 and the second rack 52, which has a compact structure and strong stability.

[0113] The first elastic element is a first compression spring 110 installed between the base 1 and the base 2. In this application, the first compression spring 110 is preferably sleeved on the connecting rod 11. Alternatively, the two ends of the first compression spring 110 can be directly fixed to the base 1 and the base 2 respectively.

[0114] In practice, depending on the actual situation, a tension spring installed between the base 2 and the mounting base 3 can be selected as the first elastic element. In this embodiment, a first compression spring 110 installed between the base 1 and the base 2 is used as the first elastic element, so that the base 2 has an upward movement tendency relative to the base 1. The structure is simple, easy to install, and highly practical.

[0115] The travel indication mechanism includes a pointer 31 and a scale 310;

[0116] Pointer 31 is fixedly mounted on mounting base 3;

[0117] The scale line 310 is set on the lifting frame 4.

[0118] The stroke indication mechanism is formed by the pointer 31 fixedly installed on the mounting base 3 and the scale line 310 set on the lifting frame 4. The relative position between the lifting frame 4 and the mounting base 3 is used to display the relative position between the base 1 and the base 2, thereby completing the measurement of the distance between the upper end face of the measuring scale 12 and the lower end face of the base 2. This completes the purpose of displaying the engagement depth between the door slider 101 and the sill groove 102. The structure is simple and easy to use.

[0119] The lifting frame 4 includes a frame body 41 and a slider 42;

[0120] The slider 42 is slidably mounted on the frame 41 along the length of the connecting rod 11, and the scale line 310 is set on the slider 42;

[0121] The frame 41 is equipped with a synchronization mechanism that drives the slider 42 to move upward synchronously;

[0122] A connecting block 30 is fixedly provided on the mounting base 3, and a top block 421 is rotatably mounted on the connecting block 30. The top block 421 is tilted from top to bottom away from the slider 42.

[0123] A pressure block 422 is fixedly provided on the top block 421. A second elastic element is installed between the pressure block 422 and the connecting block 30. The second elastic element is used to drive the top block 421 to press against the slider 42 via the pressure block 422.

[0124] Through the cooperation of the frame 41, slider 42, synchronization mechanism, top block 421, pressure block 422 and second elastic element, during the process of pulling the lifting frame 4 upward, the frame 41 drives the slider 42 to overcome the friction between the slider 42 and the top block 421 and move upward synchronously until the base 2 moves downward to contact the groove edge of the sill 102.

[0125] At this time, the lifting frame 4 can be moved downwards, so that the measuring scale 12 and the base 2 move away from each other. After releasing the clamp on the door slider 101, the detection device can be taken out from the sill groove 102.

[0126] During this process, the top block 421 pushes against the slider 42, so that the relative position between the slider 42 and the mounting base 3 does not change. In turn, in conjunction with the pointer 31 fixedly installed on the mounting base 3, the reading is taken after the detection device is removed from the sill groove 102, making the reading more convenient.

[0127] A guide block is installed on the base 2, and a slide rail fitted on the guide block is fixedly installed on the frame 41.

[0128] In practice, depending on the actual situation, a guide hole can be directly opened on the base 2, and the frame 41 itself can be used as a slide rail to pass through the guide hole to complete the vertical sliding installation of the lifting frame 4 on the base 2 through the cooperation of the guide block and the slide rail. The structure has high stability and strong practicality.

[0129] The synchronization mechanism is a sliding groove 410 opened on the frame 41, and the slider 42 is slidably installed in the sliding groove 410;

[0130] The bottom of the sliding groove 410 forms a support surface for supporting the slider 42.

[0131] In practice, depending on the actual situation, a support block can be set on the frame 41 below the slider 42 to support the slider 42. The support block supports the slider 42, which drives the slider 42 to move upward synchronously with the frame 41. In this embodiment, through the mutual cooperation between the slider 42 and the sliding groove 410, on the basis of completing the sliding installation between the slider 42 and the frame 41, a support surface for supporting the slider 42 can also be formed from the bottom of the sliding groove 410. The structure is simple and has strong practicality.

[0132] A third elastic element 411 is provided between the frame 41 and the slider 42 to drive the slider 42 to move downward. The third elastic element 411 is preferably a compression spring installed at the top of the slider 42 and the top of the sliding groove 410. Alternatively, mounting blocks can be provided on the frame 41 and the slider 42 respectively, with the mounting block of the frame 41 located below the mounting block of the slider 42, and a tension spring can be installed between the two mounting blocks as the third elastic element 411.

[0133] In practice, the third elastic element 411 can be omitted. After pressing the pressure block 422 to disengage the top block 421 from the slider 42, the slider 42 can be manually reset. In this embodiment, by setting the third elastic element, after the reading is completed, pressing the pressure block 422 overcomes the elastic force of the second elastic element, so that after the top block 421 disengages from the slider 42, the slider 42 can automatically reset under the action of the third elastic element 411, making it more convenient to use.

[0134] In this embodiment, the top block 421 is covered with a rubber sleeve, which replaces the slider 42 in contact with the top block 421. This reduces the maintenance cost of the detection device by replacing the rubber sleeve when it wears out.

[0135] At the same time, the characteristic of the rubber sleeve deforming under pressure can be used to increase the contact area with the slider 42, thereby making the friction between the top block 421 and the slider 42 greater. This avoids the slider 42 automatically resetting under the elastic force of the third elastic element 411 when the pressure block 422 is not pressed because the elastic force of the third elastic element 411 is greater than the friction between the top block 421 and the slider 42. This is highly practical.

[0136] Of course, the prestress of the second elastic element can also be increased to make the pressure between the top block 421 and the slider 42 greater, thereby avoiding the problem that the slider 42 automatically resets when the pressure block 422 is not pressed.

[0137] The lifting frame 4 also includes a crossbar 43, which is fixedly installed on the frame body 41 and located above the transmission mechanism;

[0138] The free end of the horizontal bar 43 is slidably connected to the vertical bar;

[0139] A handle 44 is provided on the crossbar 43, and the handle 44 is located above the transmission mechanism.

[0140] In fact, the lifting frame 4 can also be lifted directly according to the actual situation. In this embodiment, the setting of the crossbar 43 can provide installation space for the handle 44, which makes it more convenient to lift the lifting frame 4 upward.

[0141] At the same time, the crossbar 43 can also provide a second sliding connection structure between the lifting frame 4 and the base 2, improving the overall structural stability of the device and making it highly practical.

[0142] In this embodiment, before use, the base 1 and the base 2 are in an open state under the pushing action of the first compression spring 110.

[0143] Slider 42 is located at the bottom of sliding groove 410 under the action of the third elastic element 411;

[0144] When in use, place the detection device into the sill groove 102 and fix it to the side of the door slider 101 on the elevator landing door until the base 1 reaches the bottom of the sill groove 102. Then push the detection device horizontally so that the measuring ruler 12 is inserted into the gap between the bottom of the door slider 101 and the bottom of the sill groove 102.

[0145] Then, by pulling the lifting frame 4 upwards using handle 44, the entire detection device moves upwards until the upper surface of the measuring scale 12 is against the bottom of the door slider 101. Figure 1 As shown;

[0146] Continue pulling the lifting frame 4 to overcome the prestress of the first compression spring 110, causing the lifting frame 4 to move upward relative to the mounting base 3. This, in turn, drives the gear 50 to rotate counterclockwise via the second rack 52, which in turn drives the first rack 51 to move downward, thereby causing the base 2 to move downward until it contacts the upper edge of the groove in the sill 102. Figure 2 As shown;

[0147] During this process, the top block 421, under the action of the pressure block 422 and the second elastic element, always presses against the slider 42, and the bottom of the sliding groove 410 serves as the support surface, driving the slider 42 to move upward synchronously with the lifting frame 4, so that relative movement occurs between the top block 421 and the slider 42.

[0148] Then, the lifting frame 4 is moved downward a certain distance so that the measuring scale 12 is disengaged from the door slider 101 and the base 2 is in contact with the groove edge of the sill groove 102. Then it is moved laterally so that the measuring scale 12 is disengaged from below the door slider 101. Finally, it is pulled upward so that the detection device is disengaged from the sill groove 102.

[0149] During this process, the top block 421, under the action of the pressure block 422 and the second elastic element, always presses against the slider 42, restricting the slider 42 from moving downward relative to the mounting base 3, thereby ensuring that the relative position of the pointer 31 mounted on the mounting base 3 via the connecting block 30 and the scale line 310 on the slider 42 does not change.

[0150] At this point, the distance between the upper end face of the measuring scale 12 and the lower end face of the base 2 can be determined by reading the scale line on the slider 42 with the pointer 31 outside the sill groove 102, thereby obtaining the depth dimension of the door slider 101 inserted into the sill groove 102, that is, the engagement depth of the door slider 101.

[0151] After the reading is completed, the pressure block 422 is pressed, causing the top block 421 to disengage from the top block of the slider 42. The slider 42 can then be reset under the action of the third elastic element 411 for secondary use.

[0152] Example 3:

[0153] like Figure 5 As shown, the structural difference between this embodiment and Embodiment 1 lies in the following:

[0154] The travel indication mechanism includes a pointer 31 and a scale 310;

[0155] Pointer 31 is fixedly mounted on base 2;

[0156] The scale line 310 is set on the lifting frame 4.

[0157] The stroke indication mechanism is formed by the pointer 31 fixedly installed on the base 2 and the scale line 310 set on the lifting frame 4. The relative position between the lifting frame 4 and the base 2 is used to display the relative position between the base 1 and the base 2, thereby completing the measurement of the distance between the upper end face of the measuring scale 12 and the lower end face of the base 2, thus completing the purpose of displaying the engagement depth between the door slider 101 and the sill groove 102.

[0158] The moving distance of the lifting frame 4 relative to the base 2 is twice the moving distance of the base 1 relative to the base 2. This can increase the unit size on the scale line 310. That is, the 1mm length marked on the scale line 310 is equivalent to the actual length of 2mm. This reduces the difficulty of observation, improves the measurement accuracy, and is highly practical.

[0159] The lifting frame 4 includes a frame body 41 and a slider 42;

[0160] The slider 42 is slidably mounted on the frame 41 along the length of the connecting rod 11, and the scale line 310 is set on the slider 42;

[0161] The frame 41 is equipped with a synchronization mechanism that drives the slider 42 to move upward synchronously;

[0162] A connecting block 30 is fixedly provided on the base 2, and a top block 421 is rotatably mounted on the connecting block 30. The top block 421 is inclined from top to bottom away from the slider 42.

[0163] A pressure block 422 is fixedly provided on the top block 421. A second elastic element is installed between the pressure block 422 and the connecting block 30. The second elastic element is used to drive the top block 421 to press against the slider 42 via the pressure block 422. The second elastic element is one of a compression spring, a torsion spring, or a spring sheet. In this embodiment, a compression spring is preferred.

[0164] Through the cooperation of the frame 41, slider 42, synchronization mechanism, top block 421, pressure block 422 and second elastic element, during the process of pulling the lifting frame 4 upward, the frame 41 drives the slider 42 to overcome the friction between the slider 42 and the top block 421 and move upward synchronously until the base 2 moves downward to contact the groove edge of the sill 102.

[0165] At this time, the lifting frame 4 can be moved downwards, so that the measuring scale 12 and the base 2 move away from each other. After releasing the clamp on the door slider 101, the detection device can be taken out from the sill groove 102.

[0166] During this process, the top block 421 pushes against the slider 42, so that the relative position between the slider 42 and the base 2 does not change. In conjunction with the pointer 31 fixedly installed on the base 2, the reading is taken after the detection device is removed from the sill groove 102, making the reading more convenient.

[0167] The above provides a detailed description of the elevator door slider engagement depth detection device provided by the present invention. The specific embodiments are described only to help understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
