Description

Technical Field

[0001] The utility model relates to the technical field of life test, in particular to a blackboard push-pull life test device. Background Art

[0002] Blackboard is a very important teaching tool in modern education. Blackboard is usually installed on the guide rail. By pushing and pulling the blackboard, the blackboard can slide on the guide rail to improve the convenience and flexibility of the blackboard. As the use time increases, pushing and pulling will cause the guide rail to wear and deform, resulting in push-pull jams, etc., affecting normal teaching activities. Therefore, the push-pull life of the blackboard is one of the important indicators of the performance of the blackboard. It is of great significance to test the push-pull life of the blackboard before leaving the factory.

[0003] At present, the method for detecting the push-pull life of the blackboard usually relies on manual testing, that is, manually pushing and pulling the blackboard back and forth and counting the number of push-pull times until the blackboard can no longer be pushed to obtain the push-pull life of the blackboard.

[0004] However, manual testing usually takes a long time to complete, resulting in extremely high labor and time costs for testing. It is also prone to human errors such as omissions and miscalculations of the number of push and pull times, which affects the accuracy of the test. Utility Model Content

[0005] The embodiment of the utility model aims to provide a blackboard push-pull life test device to solve the technical problem that the blackboard push-pull life in the prior art relies on manual testing and has a high testing cost.

[0037] In order to facilitate the understanding of the utility model, the utility model is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connecting" another element, it can be directly on another element, or there can be one or more centered elements therebetween.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] At present, the method of testing the push-pull life of the blackboard usually relies on manual testing, that is, manually pushing and pulling the blackboard back and forth, and counting the number of push-pull times until the blackboard can no longer be pushed to obtain the push-pull life of the blackboard. However, manual testing usually takes a long time to complete, resulting in extremely high labor and time costs for the test, and is prone to human errors such as omissions and miscalculations of the number of push-pull times, affecting the accuracy of the test.

[0040] In order to solve the above problems existing in the prior art, the embodiment of the utility model provides a blackboard push-pull life test device, which clamps the blackboard handle through a clamping module, drives the clamping module to do reciprocating linear motion through a driving module, and then pushes the blackboard to do push-pull motion, and records the number of times the blackboard is pushed and pulled through a counting module, thereby realizing the automatic detection of the blackboard push-pull life, reducing the cost and error of manual testing, and improving the test efficiency and the accuracy of the test data. In addition, through the sliding cooperation of the fastener and the first slide groove, the installation height of the clamping assembly on the mounting seat can be adjusted, so as to meet the push-pull life test of blackboards with different installation heights, and through the sliding cooperation of the fastener and the second slide groove, the spacing between the two clamps can be adjusted to meet the clamping of blackboard handles of different sizes, thereby improving the versatility of the blackboard push-pull life test device.

[0041] The following will be combined with the attached Figures 1 to 6 The blackboard push-pull life test device provided in the embodiment of the utility model is elaborated in detail.

[0042] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the decomposition structure of the blackboard push-pull life test device. Figure 2 It is a structural schematic diagram of the clamping module.

[0043] An embodiment of the utility model provides a blackboard push-pull life test device 100, including a clamping module 10, a driving module 20 and a counting module 30. The clamping module 10 includes a mounting seat 11 and a clamping assembly 12 arranged on the mounting seat 11. The clamping assembly 12 is slidably matched with the mounting seat 11 to adjust the installation height of the clamping assembly 12 on the mounting seat 11. The clamping assembly 12 is used to clamp the blackboard. The driving module 20 is matched with the mounting seat 11 to drive the clamping module 10 to perform reciprocating linear motion, and the clamping module 10 drives the blackboard to perform push-pull motion. The counting module 30 is arranged on the driving module 20 to record the number of push-pull times of the blackboard.

[0044] The blackboard push-pull life test device 100 includes a driving module 20, a clamping module 10 and a computing module. The driving module 20 can be a slide module. Optionally, the slide module is a synchronous belt linear slide module or a ball screw linear slide module, etc. These slide modules have high transmission accuracy and can drive the clamping module 10 and the blackboard to perform high-precision linear reciprocating motion to ensure stability during the blackboard life test.

[0045] The clamping module 10 includes a mounting seat 11 and a clamping assembly 12. The mounting seat 11 is mounted on a driving module 20. The clamping assembly 12 is mounted on the mounting seat 11. The driving module 20 drives the mounting seat 11 to make reciprocating linear motion, thereby driving the entire clamping assembly 12 to make reciprocating linear motion. The clamping assembly 12 is used to clamp the blackboard, so that the blackboard can make reciprocating direct motion together with the clamping assembly 12, that is, to achieve the push-pull action of the blackboard. For example, the clamping assembly 12 has a clamping space 120. By clamping the handle of the blackboard in the clamping space 120, the blackboard can make reciprocating linear motion together with the clamping assembly 12.

[0046] The counting module 30 is arranged on the driving module 20, and is used for recording the number of times the blackboard is pushed and pulled. Specifically, each time the clamping assembly 12 drives the blackboard to complete a pushing and pulling action, the number of pushing and pulling recorded by the counting module 30 is accumulated once until the clamping assembly 12 can no longer push the blackboard. At this time, the number of pushing and pulling recorded by the counting module 30 represents the pushing and pulling life of the blackboard.

[0047] In this embodiment, the blackboard is clamped on the clamping module 10, and then the driving module 20 is started. The driving module 20 drives the clamping module 10 to perform reciprocating linear motion, and then pushes the blackboard to perform a push-pull action. During this process, the counting module 30 records the number of push-pull actions of the blackboard. The push-pull life of the blackboard can be obtained when the blackboard can no longer be pushed, thereby realizing automatic detection of the push-pull life of the blackboard, reducing manual testing costs and errors, and improving testing efficiency and the accuracy of test data.

[0048] In addition, since the clamping assembly 12 is slidably matched with the mounting seat 11, the installation height of the clamping assembly 12 on the mounting seat 11 is adjustable. In this way, by adjusting the installation height of the clamping assembly 12 on the mounting seat 11, the push-pull life test of the blackboard with different installation heights can be performed, thereby improving the versatility of the blackboard push-pull life test device 100.

[0049] like Figure 2 As shown, in some embodiments, the clamping module 10 also includes a fastener 13, and the clamping assembly 12 is fixedly connected to the mounting seat 11 through the fastener 13. One of the mounting seat 11 and the clamping assembly 12 is provided with a first slide groove 110. The fastener 13 is loosened, and the fastener 13 slides in cooperation with the first slide groove 110 to adjust the installation height of the clamping assembly 12 on the mounting seat 11.

[0050] Optionally, the fastener 13 includes a bolt and a nut, and one of the mounting seat 11 and the clamping assembly 12 is provided with a first slide groove 110, the length direction of the first slide groove 110 is the vertical direction (height direction), and the other may be provided with a through hole for the bolt to pass through. During assembly, the rod of the bolt is passed through the through hole and the first slide groove 110, and then the nut is tightened to complete the fixation of the clamping assembly 12 on the mounting seat 11.

[0051] When it is necessary to adjust the installation height of the clamping assembly 12 on the mounting base 11, loosen the nut. At this time, the bolt can slide relative to the first slide groove 110, and drive the clamping assembly 12 to slide relative to the first slide groove 110, thereby adjusting the installation height of the clamping assembly 12. After the clamping assembly 12 is adjusted to an appropriate height, tighten the nut to complete the adjustment of the installation height of the clamping assembly 12, thereby meeting the push-pull life test of blackboards with different installation heights.

[0052] In some embodiments, the clamping assembly 12 includes two clamping members 121, which are fixedly connected to the mounting base 11 via fasteners 13 respectively. The handle of the blackboard can be clamped between the two clamping members 121, and one of the mounting base 11 and the clamping member 121 is provided with a first sliding groove 110.

[0053] Specifically, the clamping assembly 12 includes two clamping members 121 , each of which can be fixedly mounted on the mounting base 11 by a fastener 13 , and there is a distance between the two clamping members 121 , so as to facilitate clamping the blackboard handle in the clamping space 120 between the two clamping members 121 .

[0054] One of the mounting seat 11 and the clamping member 121 is provided with a first slide groove 110. For example, the mounting seat 11 is provided with two first slide grooves 110, and the two clamping members 121 are provided with through holes respectively. The two through holes correspond to and communicate with the two first slide grooves 110. During assembly, the rod of the bolt is passed through the through hole and the corresponding first slide groove 110, and then the nut is tightened to install the clamping member 121 on the mounting seat 11. When it is necessary to adjust the installation height of the clamping assembly 12 on the mounting seat 11, the nut is loosened, and the bolt can slide relative to the first slide groove 110, and drive the clamping member 121 to slide relative to the first slide groove 110, thereby adjusting the installation height of the clamping member 121.

[0055] It is understandable that in other embodiments, the mounting base 11 may be provided with a through hole for the bolt to pass through, and the two clamping members 121 may be respectively provided with a first slide groove 110. Since the installation heights of the two clamping members 121 on the mounting base 11 are adjustable, the two clamping members 121 may be adjusted to an appropriate height to meet the requirements of clamping blackboard handles of different installation heights.

[0056] See also Figure 3 and Figure 4 , and refer back to Figure 2 , Figure 3 It is a schematic diagram of the three-dimensional structure of the clamping part. Figure 4 It is a schematic diagram of the three-dimensional structure of the adjustment plate.

[0057] In some embodiments, the other of the mounting base 11 and the clamping member 121 is provided with a second slide groove 1210, and the first slide groove 110, the second slide groove 1210 and the fastener 13 are fastened together to fix the connection between the clamping member 121 and the mounting base 11, and the fastener 13 is loosened, and the fastener 13 and the second slide groove 1210 are slidably matched to adjust the distance between the two clamping members 121, so that the two clamping members 121 can clamp blackboard handles of different thicknesses.

[0058] One of the mounting seat 11 and the clamping member 121 is provided with a first sliding groove 110, and the other is provided with a second sliding groove 1210, that is, when the mounting seat 11 is provided with a first sliding groove 110, the clamping member 121 is provided with a second sliding groove 1210, and when the mounting seat 11 is provided with a second sliding groove 1210, the clamping member 121 is provided with a first sliding groove 110.

[0059] The fastener 13 includes a bolt and a nut. During assembly, after the bolt passes through the first slide groove 110 and the second slide groove 1210, the nut is tightened to complete the fixing of the clamping member 121 on the mounting seat 11. For ease of description, the first slide groove 110 is provided on the mounting seat 11, and the second slide groove 1210 is provided on the clamping member 121 for illustration.

[0060] On the one hand, after loosening the nut, the bolt can slide with the first slide groove 110, the bolt can slide along the first slide groove 110, and drive the clamping member 121 to slide relative to the first slide groove 110, thereby adjusting the installation height of the clamping member 121 on the mounting seat 11; on the other hand, after loosening the nut, the bolt can also slide with the second slide groove 1210, so that the clamping member 121 can move relative to the bolt, thereby, the two clamping members 121 can move toward or away from each other, thereby adjusting the distance between the two clamping members 121, so that it can clamp blackboard handles of different thicknesses, thereby improving the adaptability to the size of the blackboard handles.

[0061] It is understandable that in other embodiments, the second slide groove 1210 may be provided on the mounting seat 11 and the first slide groove 110 may be provided on the clamping member 121 , which can also achieve the above-mentioned effect, and will not be described in detail here.

[0062] like Figure 3 As shown, in some embodiments, each clamping member 121 includes a connecting portion 1211 and a clamping portion 1212, the connecting portion 1211 is fixedly connected to the mounting base 11 by a fastener 13, the clamping portion 1212 is arranged at an angle to the connecting portion 1211, and the two clamping portions 1212 are relatively spaced apart to form a clamping space 120 for clamping a handle of the blackboard.

[0063] The clamping member 121 includes a connecting portion 1211 and a clamping portion 1212 that are fixedly connected. For example, the connecting portion 1211 and the clamping portion 1212 can be an integrally formed structure to improve the structural strength. The connecting portion 1211 and the mounting seat 11 are both plate-like structures and are arranged at an angle. The connecting portion 1211 fits well with the mounting seat 11 to facilitate the fixed connection between the connecting portion 1211 and the mounting seat 11. The clamping portion 1212 is arranged at an angle to the connecting portion 1211 so that a clamping space 120 for clamping the blackboard handle can be formed between the two clamping portions 1212.

[0064] Optionally, the mounting seat 11 is provided with a first slide groove 110, the connecting portion 1211 is provided with a second slide groove 1210, and the fastener 13 is tightly matched with the first slide groove 110 and the second slide groove 1210 to achieve a fixed connection between the connecting portion 1211 and the mounting seat 11. Optionally, the clamping portion 1212 is arranged at an angle to the connecting portion 1211, so that the two clamping portions 1212 are parallel to each other, so that they can better fit with the square blackboard handle.

[0065] In some embodiments, the length direction of the second slide groove 1210 is perpendicular to the length direction of the first slide groove 110 .

[0066] Specifically, the length direction of the first slide groove 110 corresponds to the vertical direction, which makes it convenient to adjust the installation height of the clamping member 121 through the first slide groove 110, so that the two clamping members 121 can clamp the blackboard handles of different installation heights. The length direction of the second slide groove 1210 corresponds to the length direction of the blackboard (that is, the thickness direction of the blackboard handle), which makes it convenient to adjust the two clamping members 121 through the second slide groove 1210, so that the two clamping members 121 can clamp the blackboard handles of different thicknesses.

[0067] In some embodiments, at least three first sliding grooves 110 arranged in parallel with each other are arranged on the mounting seat 11 , and two adjacent first sliding grooves 110 are arranged with relative spacing.

[0068] A second slide groove 1210 is respectively provided on the two clamping members 121. By respectively cooperating the two clamping members 121 with the first slide grooves 110 at different positions on the mounting seat 11, the installation positions of the two clamping members 121 on the mounting seat 11 can be changed, so as to facilitate further adjustment of the distance between the two clamping members 121, so that the adjustable range of the distance between the two clamping members 121 is larger, and the two clamping members 121 can clamp thicker and thinner blackboard handles, further improving the adaptability of clamping the blackboard handles.

[0069] In some embodiments, the clamping module 10 also includes an adjustment plate 14, which is arranged between the two clamping members 121 and the mounting seat 11. A connecting hole 140 is opened on the adjustment plate 14, and the first slide groove 110, the connecting hole 140, the second slide groove 1210 and the fastener 13 are fastened together.

[0070] The adjustment plate 14 is located between the clamping member 121 and the mounting seat 11. The adjustment plate 14 is provided with connection holes 140 corresponding to the first slide groove 110 and the second slide groove 1210. It can be understood that there are at least two connection holes 140, so that the two clamping members 121 can be fixed to the mounting seat 11 through the adjustment plate 14. During assembly, the first slide groove 110, the connection hole 140 and the second slide groove 1210 are aligned, and then one end of the bolt is passed through the first slide groove 110, the connection hole 140 and the second slide groove 1210 and fixed with the nut, so that the clamping member 121 can be assembled and fixed to the mounting seat 11.

[0071] When it is necessary to adjust the installation height of the clamping member 121 on the mounting seat 11, loosen the fastener 13, and the fastener 13 slides in the first slide groove 110, driving the adjustment plate 14 and the two clamping members 121 to slide relative to the first slide groove 110, thereby adjusting the installation height of the two clamping members 121.

[0072] In this embodiment, the setting of the adjustment plate 14, on the one hand, facilitates the adjustment of the installation position of the two clamps 121, so that the two clamps 121 can be maintained at the same height, thereby improving the assembly position accuracy of the two clamps 121; on the other hand, the adjustment plate 14 can also act as a gasket to ensure the assembly stability of the clamps 121 on the mounting seat 11.

[0073] In some embodiments, at least three connection holes 140 are provided on the adjustment plate 14. Figure 4 As shown, three connecting holes 140 are opened on the adjustment plate 14, and three first sliding grooves 110 are opened on the mounting seat 11, wherein two connecting holes 140 and two first sliding grooves 110 are respectively used for fixed connection with two clamping members 121, and another connecting hole 140 and the first sliding groove 110 are fastened together by fasteners 13 to realize direct fixation of the adjustment plate 14 and the mounting seat 11, thereby improving the assembly stability of the adjustment plate 14 on the mounting seat 11.

[0074] Refer to 5 and 6, and refer again to Figure 1 , Figure 5 is a schematic diagram of the three-dimensional structure of the substrate. Figure 6 It is a three-dimensional structural schematic diagram of the mounting plate.

[0075] In some embodiments, the driving module 20 includes a movable panel 21 (see Figure 1 ), the mounting seat 11 includes a vertically arranged base plate 111 and a mounting plate 112, the base plate 111 is fixedly connected to the movable panel 21, and the mounting plate 112 is slidably matched with the clamping assembly 12.

[0076] like Figure 1 As shown, the driving module 20 (such as a slide module) has a movable panel 21 that can drive the clamping module 10 to perform reciprocating linear motion. The mounting seat 11 includes a base plate 111 and a mounting plate 112 that are perpendicular to each other. Optionally, the base plate 111 and the mounting plate 112 are an integrally formed structure.

[0077] The substrate 111 and the mounting plate 112 are both roughly plate-like structures. The substrate 111 is fixedly connected to the movable panel 21. Optionally, the substrate 111 is arranged in a horizontal direction and fits with the movable panel 21, so that it is convenient to be fixed to the movable panel 21 by fasteners 13 such as screws. The mounting plate 112 is arranged in a vertical direction to facilitate sliding cooperation with the clamping member 121, thereby adjusting the installation position of the clamping member 121 on the mounting plate 112.

[0078] like Figure 2 As shown, a first slide groove 110 for adjusting the installation height of the clamping member 121 is provided on the mounting plate 112, and a second slide groove 1210 for adjusting the distance between the two clamping members 121 is respectively provided on the two clamping members 121. During assembly, the clamping member 121 is fixedly assembled on the mounting plate 112 by fastening the fastener 13 with the first slide groove 110, the connecting hole 140 and the second slide groove 1210.

[0079] It is understandable that in other embodiments, a second slide groove 1210 for adjusting the distance between the two clamping members 121 may be provided on the mounting plate 112 , and the two clamping members 121 may each be provided with a first slide groove 110 for adjusting their own mounting height.

[0080] Optionally, a first threaded hole 1110 is provided on the substrate 111, and a second threaded hole 210 is provided on the movable panel 21. When the substrate 111 and the movable panel 21 are assembled, screws or other fasteners 13 are screwed into the first threaded hole 1110 and the second threaded hole 210 in sequence to complete the fixed assembly of the substrate 111 on the movable panel 21.

[0081] In some embodiments, the substrate 111 and the mounting plate 112 are fixedly connected by countersunk screws, which can be sunken into the interior of the substrate 111 to prevent the fastener 13 from protruding from the surface of the substrate 111 and thereby hindering the substrate 111 from fitting with the movable panel 21. Optionally, a countersunk hole 1111 is provided on the substrate 111, and a third threaded hole 1120 is provided on the side of the mounting plate 112 facing the substrate 111. During assembly, the countersunk screws are screwed into the countersunk hole 1111 and the third threaded hole 1120 in turn to complete the fixed connection between the mounting plate 112 and the substrate 111.

[0082] In some embodiments, the counting module 30 includes a proximity switch 31 and a counter 32. The proximity switch 31 is installed on the driving module 20 and is electrically connected to the counter 32. Every time the moving panel 21 passes the proximity switch 31, the counter 32 counts once, indicating that the moving panel 21 drives the blackboard through the clamping assembly 12 to complete a push-pull action, until the clamping assembly 12 can no longer push the blackboard. At this time, the number of push-pull times recorded by the counter 32 represents the push-pull life of the blackboard.
