Description

Technical Field

[0001] The present application relates to the technical field of magnetic switches, and in particular to a magnetic switch performance testing device. Background Art

[0002] The magnetic switch is a passive electronic switch device. The magnetic switch is used to start the car. If a fault occurs, the car will not start. Therefore, the magnetic switch needs to be tested by a detection device before leaving the factory to avoid defective magnetic switches that cause the car to fail to start.

[0003] In the related art, the testing device includes a base, a detection structure and a mounting structure on the base, the detection structure can detect the magnetic switch, and the mounting structure includes a mounting seat, and the mounting seat is provided with a mounting groove for detecting the magnetic switch.

[0004] Since the sizes of magnetic switches are different, it is difficult for the test device to adapt to magnetic switches of different sizes, so the adaptability of the test device is low, which affects the use of the test device. Summary of the invention

[0005] In order to improve the problem that the testing device is difficult to adapt to magnetic switches of different sizes, the present application provides a magnetic switch performance testing device.

[0006] The present application provides a magnetic switch performance testing device, which adopts the following technical solution: A magnetic switch performance testing device comprises a base, on which a detection structure and a mounting structure are provided, the detection structure is used to detect the magnetic switch, the mounting structure comprises a mounting seat, on which a mounting rod is provided, on which two mounting plates are slidably connected, and on which a limiting structure for limiting the movement of the mounting plate is provided, and the magnetic switch is placed between the two mounting plates.

[0007] By adopting the above technical solution, the staff slides the mounting plate to make the distance between the two mounting plates different, and uses a limiting structure to fix the two mounting plates, so that magnetic switches of different sizes can be placed between the two mounting plates, and the magnetic switch can be fixed on the mounting base, so that magnetic switches of different sizes can be tested by the test device, increasing the applicability of the test device.

[0008] Optionally, the limiting structure includes a rotating rod and a plurality of limiting blocks, the rotating rod is rotatably connected to the mounting seat, the limiting blocks are fixedly connected to the rotating rod, the limiting blocks are distributed along the length direction of the rotating rod, and different limiting blocks have different orientations, and a limiting groove for inserting the limiting blocks is provided on the mounting plate; when the limiting block is inserted into the limiting groove, the limiting plate is fixed on the mounting rod.

[0009] By adopting the above technical solution, the staff rotates the rotating rod so that the rotating rod can drive the limit block to move. Since the limit block is distributed along the length direction of the rotating rod, the limit groove and the limit block in the mounting plate can be aligned, so that the limit block can be located in the limit groove, so that the mounting plate can be fixed on the mounting rod, reducing the possibility of the mounting plate sliding on the mounting rod, so that the magnetic switch can be more stably located between the two mounting plates.

[0010] Optionally, a stop spring is provided on the mounting seat, a stop strip is provided on the stop spring, a stop block is provided on the stop strip, and the stop spring drives the stop block to be located on the moving path of the detection structure; when the stop block is located on the moving path of the detection structure, the detection structure cannot detect the magnetic switch.

[0011] By adopting the above technical solution, the stop strip is driven to move by the stop spring, and the stop strip drives the stop block to move, so that the stop block is located on the moving path of the detection structure, making it difficult for the detection structure to detect the magnetic switch, thereby preventing the staff from accidentally touching the switch and causing the detection structure to be activated; when the magnetic switch is installed in place, the staff presses the stop strip to make the stop block leave the moving path of the detection structure. At this time, the detection structure can detect the magnetic switch, thereby realizing the detection of the magnetic switch by the detection structure.

[0012] Optionally, the limit block is located on the moving path of the stop bar; when the limit block is inserted into the limit groove, the other limit block abuts against the stop bar, and at this time the stop block is not on the moving path of the detection structure.

[0013] By adopting the above technical solution, when the limit block is inserted into the limit groove, the limit block is located on the moving path of the stop bar, so that another limit block abuts the stop bar, so that the stop bar stops moving due to the abutment of the limit block, so that the stop block is not on the moving path of the detection structure, so that the subsequent detection structure can detect the magnetic switch; when the magnetic switch is not installed, the limit block is not in the limit groove. At this time, the limit block does not limit the movement of the stop bar, so that the stop bar can drive the stop block to limit the movement of the detection structure, thereby avoiding the danger to the staff when the detection structure is activated when the staff is installing the magnetic switch.

[0014] Optionally, an operating groove is provided on the rotating rod for inserting a tool, a mounting hole is provided on the mounting seat for the rotating rod to pass through, and a mounting cover is slidably connected to the mounting seat, and the mounting cover is used to block the opening of the mounting hole.

[0015] By adopting the above technical solution, the staff slides the installation cover so that the installation cover does not block the opening of the installation hole. At this time, the staff can insert the tool into the operating groove and rotate the rotating rod with the tool; when there is no need to rotate the rotating rod, the staff removes the tool from the rotating rod and then slides the installation cover so that the installation cover can block the opening of the installation hole, making it difficult for the rotating rod to rotate, thereby making it difficult for the limit block to disengage from the limit groove, thereby further strengthening the limit of the limit block on the mounting plate.

[0016] Optionally, a receiving block is rotatably connected to the mounting cover, and a receiving groove is provided on the mounting seat; when the receiving block is located in the receiving groove, the mounting cover blocks the mounting hole.

[0017] By adopting the above technical solution, the staff rotates the accommodating block to insert the accommodating block into the accommodating groove. At this time, the mounting cover blocks the mounting hole, so that the mounting cover can block the mounting hole more stably.

[0018] Optionally, a placement plate is detachably connected to the mounting seat, and a placement hole is formed on the placement plate, and the placement hole is used to support the magnetic switch.

[0019] By adopting the above technical solution, a placement hole is opened on the placement plate, so that the magnetic switch can be placed on the placement hole. The magnetic switch can abut the hole wall of the placement hole and the two mounting plates, thereby increasing the stability of the installation of the magnetic switch. At the same time, different placement plates can be replaced to allow placement holes of different sizes to adapt to different magnetic switches.

[0020] Optionally, a moving bar is slidably connected to the mounting seat, the moving bar and the rotating rod are engaged with each other, the moving bar is provided with a moving groove for inserting a placement plate, and a plurality of moving grooves are provided, and the mounting seat is provided with a through hole for inserting the placement plate; when the placement plate is inserted into the moving groove through the through hole, the limit block is located in the limit groove.

[0021] By adopting the above technical solution, when the rotating rod rotates, the rotating rod and the moving bar are engaged with each other, so that the rotating rod can drive the moving bar to slide on the mounting seat, allowing the placement plate to be inserted into the moving groove to achieve mutual fixation of the placement plate and the moving bar; the placement plate is passed through the through hole, and the placement plate is located in the through hole and the moving groove, so that the placement plate can restrict the moving bar to prevent the moving bar from sliding, and the moving bar and the rotating rod are engaged with each other, so that the rotating rod cannot rotate.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The staff slides the mounting plates to make the distance between the two mounting plates different, and fixes the two mounting plates with a limit structure, so that magnetic switches of different sizes can be placed between the two mounting plates, and the magnetic switches can be fixed on the mounting base, so that magnetic switches of different sizes can be tested by the test device, increasing the applicability of the test device.

[0023] 2. When the limit block is inserted into the limit groove, the limit block is located on the moving path of the stop strip, so that another limit block abuts the stop strip, so that the stop strip stops moving due to the abutment of the limit block, so that the stop block is not on the moving path of the detection structure, so that the subsequent detection structure can detect the magnetic switch; when the magnetic switch is not installed, the limit block is not in the limit groove. At this time, the limit block does not limit the movement of the stop strip, so that the stop strip can drive the stop block to limit the movement of the detection structure, thereby avoiding danger to the staff when the detection structure is activated when the staff is installing the magnetic switch.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] Example 1 This embodiment discloses a magnetic switch performance testing device. Figure 1 A magnetic switch performance testing device includes a detection structure 1 and a mounting structure 2. The detection structure 1 can detect the magnetic switch, and the mounting structure 2 is used to install the magnetic switch.

[0028] Reference Figure 2 The mounting structure 2 includes a mounting seat 21, to which two mounting rods 22 are fixedly connected, and two mounting plates 23 are provided on the mounting seat 21, and both mounting plates 23 are slidably connected to the mounting rods 22. A magnetic switch is placed between the two mounting plates 23. A mounting bevel 231 is provided on the surface of the mounting plate 23 facing the other mounting plate 23, and the distance between the mounting bevel 231 and the other mounting plate 23 gradually decreases in the vertical downward direction, and the mounting bevel 231 is abutted against the outer surface of the magnetic switch.

[0029] Reference Figure 2 A limiting structure 3 is provided on the mounting seat 21, and the limiting structure 3 is used to limit the movement of the mounting plate 23. The limiting structure 3 includes an operating rod 31 and an operating block 32, the operating rod 31 is rotatably connected to the mounting seat 21, and the operating block 32 is fixedly connected to the end surface of the operating rod 31. The operating rod 31 is threadedly connected to the two mounting plates 23, and the thread directions at both ends of the operating rod 31 are different. One mounting plate 23 is threadedly connected to one side of the operating rod 31, and the other mounting plate 23 is threadedly connected to the other side of the operating rod 31. When the operating rod 31 rotates, the operating rod 31 drives the mounting plate 23 to move in a direction away from or close to the other mounting plate 23, thereby realizing the movement of the two mounting plates 23.

[0030] The implementation principle of Example 1 is: the staff manually rotates the operating block 32 to allow the operating block 32 to drive the operating rod 31 to rotate, and the operating rod 31 can drive the two mounting plates 23 to move so that magnetic switches of different sizes can be installed between the two mounting plates 23.

[0031] Example 2 Reference Figure 3 and Figure 4 The difference between this embodiment and the embodiment 1 is that the limiting structure 3 includes a rotating rod 33 and eight limiting blocks 34. The rotating rod 33 is rotatably connected to the mounting seat 21, and the eight limiting blocks 34 are fixedly connected to the outer surface of the rotating rod 33. The eight limiting blocks 34 are divided into two groups, and each group of limiting blocks 34 is arranged in an array along the length direction of the rotating rod 33, and different limiting blocks 34 in the same group have different directions.

[0032] Reference Figure 4The mounting plate 23 is provided with a limiting groove 24 for the limiting block 34 to be inserted, and the limiting groove 24 penetrates to the side of the mounting plate 23. When the limiting block 34 is located in the limiting groove 24, the mounting plate 23 and the rotating rod 33 are fixed to each other.

[0033] Reference Figure 5 The mounting seat 21 is fixedly connected with a receiving plate, which extends in a direction perpendicular to the length of the mounting rod 22. A plurality of retaining springs 25 are fixedly connected with the receiving plate. The mounting seat 21 is provided with a retaining bar 251, which extends in the length direction of the receiving plate. A connecting bar 252 is fixedly connected to the surface of the retaining bar 251 facing the ground, which extends in the length direction of the mounting rod 22. The length direction of the connecting bar 252 and the length direction of the retaining bar 251 are perpendicular to each other. The retaining spring 25 is fixedly connected to the end surface of the connecting bar 252 away from the retaining bar 251, and a plurality of retaining springs 25 are distributed in an array along the length direction of the connecting bar 252.

[0034] Reference Figure 3 and Figure 5 Two stop blocks 253 are fixedly connected to the surface of the stop bar 251 away from the ground, and the stop blocks 253 are located on the moving path of the detection structure 1. The stop spring 25 drives the stop bar 251 to move in the direction away from the ground, that is, the stop spring 25 drives the stop bar 251 to rise, so that the stop blocks 253 are located on the moving path of the detection structure 1. When the stop bar 251 falls, the stop spring 25 is in a compressed state, and at this time, the stop blocks 253 are not on the moving path of the detection structure 1.

[0035] Reference Figure 3 , Figure 4 and Figure 5 When the limit block 34 is inserted into the limit groove 24, the other limit block 34 abuts against the stop bar 251. At this time, the stop spring 25 is in a compressed state, and the stop block 253 is not on the moving path of the detection structure 1, so that the detection structure 1 can smoothly detect the magnetic switch. When the limit block 34 is not in the limit groove 24, the stop spring 25 drives the stop bar 251 to move, so that the stop block 253 is located on the moving path of the detection structure 1, preventing the detection structure 1 from detecting the magnetic switch when the magnetic switch is not fixed.

[0036] Reference Figure 6 An operation slot 35 is provided on the end surface of the rotating rod 33, and a tool is inserted into the operation slot 35. A mounting hole 26 is provided on the surface of the mounting seat 21 for the rotating rod 33 to pass through, and the rotating rod 33 is located in the mounting hole 26. A mounting cover 261 is slidably connected to the surface of the mounting seat 21, and the mounting cover 261 can block the opening of the mounting hole 26.

[0037] Reference Figure 6After the staff rotates the rotating rod 33 , the staff disengages the tool from the operating slot 35 , and then slides the mounting cover 261 to allow the mounting cover 261 to block the mounting hole 26 to prevent the rotating rod 33 from rotating.

[0038] Reference Figure 6 The mounting cover 261 is rotatably connected with a receiving block 262, and a receiving groove 263 communicating with the mounting hole 26 is provided on the surface of the mounting seat 21, and the receiving groove 263 is for the receiving block 262 to be inserted. When the receiving block 262 is inserted into the receiving groove 263, the mounting cover 261 can block the opening of the mounting hole 26.

[0039] Reference Figure 6 and Figure 7 The mounting seat 21 is provided with a moving cavity 27, into which the rotating rod 33 is inserted. The rotating rod 33 is fixedly connected with a first gear 271. The moving cavity 27 is slidably connected with a moving bar 272, which is meshedly connected with the first gear 271. When the rotating rod 33 rotates, the moving bar 272 slides in the moving cavity 27.

[0040] Reference Figure 7 The mounting seat 21 is provided with a placement plate 28, the mounting seat 21 is provided with a through hole 281 for the placement plate 28 to pass through, and the placement plate 28 is provided with a placement hole 282 for installing the magnetic switch. A moving groove 273 is provided on the surface of the moving bar 272 for the placement plate 28 to be inserted, and a plurality of moving grooves 273 are provided, and the plurality of moving grooves 273 are arranged in an array along the length direction of the moving bar 272.

[0041] Reference Figure 4 and Figure 7 When the rotating rod 33 rotates, the limit block 34 is located in the limit groove 24, and the rotating rod 33 drives the moving bar 272 to move through the first gear 271, so that the moving groove 273 is aligned with the through hole 281. At this time, the staff can install the placement plate 28 in the through hole 281 to achieve mutual fixation between the placement plate 28 and the moving bar 272. The placement plate 28 locks the moving bar 272 to prevent the rotating rod 33 from rotating.

[0042] The implementation principle of Example 2 is as follows: the staff first rotates the accommodating block 262, slides the installation cover 261, and rotates the rotating rod 33 through a tool to allow the limit block 34 to disengage from the limit slot 24. At this time, the staff slides the installation plate 23 to a suitable position, and then rotates the rotating rod 33 to allow the limit block 34 to be inserted into the limit slot 24, and inserts the placement plate 28 through the through hole 281 into the movable slot 273 to place the magnetic switch. Finally, the staff slides the installation cover 261 and rotates the accommodating block 262 to the accommodating slot 263.
