In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0054] For the convenience of description, the present embodiment introduces the X, Y, and Z directions for description. The X, Y, and Z directions are perpendicular to each other.

[0055] like Figures 1 to 7 As shown, this embodiment provides a photoelectric tester, including a shell 1, an outer cover 2 and a tester body 3. The shell 1 is provided with an installation cavity, the outer cover 2 can be opened and closed at the cavity opening of the installation cavity, and the tester body 3 is detachably arranged in the installation cavity.

[0056] like Figure 1 , Figure 2 as well as Figure 3 As shown, two fixing blocks 4 are arranged on the outer cover 2 at intervals along the X direction, and pin grooves are provided on the sides of the two fixing blocks 4 facing each other; a locking assembly is arranged on the outer shell 1, and the locking assembly is located between the two fixing blocks 4. The locking assembly includes a knob 7, a linkage assembly and two pins 10. The knob 7 is rotatably arranged on the outer shell 1, and the two pins 10 are arranged on both sides of the linkage assembly along the X direction. The knob 7 is used to drive the two pins 10 to move toward each other through the linkage assembly so that the pins 10 are out of the pin grooves.

[0057] The housing 1 and the outer cover 2 of the photoelectric tester are locked by the insertion and matching of the pin 10 and the pin groove. When the photoelectric tester needs to be used for testing, the knob 7 is first turned. The knob 7 drives the two pins 10 to move toward each other along the X direction through the linkage assembly, so that the pins 10 are disengaged from the corresponding pin grooves, and the outer cover 2 is unlocked on the housing 1. After that, the outer cover 2 can be opened, and the tester body 3 inside the installation cavity can be used for photoelectric testing. After use, the two pins 10 are driven to move away from each other along the X direction, so that the two pins 10 are inserted into the corresponding pin grooves, and the outer cover 2 is locked and fixed on the housing 1. At this time, due to the insertion of the pin 10 and the pin groove, the outer cover 2 can be limited to prevent the outer cover 2 from separating from the housing 1, and ensure the firmness of the outer cover 2 sealed on the housing 1.

[0058] like Figure 4 and Figure 5 As shown, two side plates 15 movable along the X direction are arranged in the installation cavity at intervals, and trapezoidal slots are arranged on the sides of the two side plates 15 facing each other, and trapezoidal pin blocks 23 are arranged on the two opposite outer walls of the tester body 3, and the trapezoidal pin blocks 23 can be inserted into the trapezoidal slots along the Z direction; an elastic buffer component is arranged between the two side plates 15 and the cavity wall of the installation cavity, and the two side plates 15 can move toward each other under the elastic force of the elastic buffer component. Furthermore, two trapezoidal slots are arranged on each side plate 15, and two trapezoidal pin blocks 23 are arranged on the two opposite outer walls of the tester body 3. A total of four trapezoidal pin blocks 23 are engaged with the corresponding four trapezoidal slots to ensure the stability of the limit of the tester body 3.

[0059] A disassembly assembly is provided on the outer shell 1, and the disassembly assembly includes a pressing plate 26 and a transmission assembly. A pressing groove 110 and a transmission cavity 120 are provided on the outer shell 1. The pressing plate 26 is slidably provided in the pressing groove 110 along the Z direction. The transmission assembly is provided in the transmission cavity 120 and is used to push the two side plates 15 to move away from each other under the drive of the pressing plate 26 so that the trapezoidal pin block 23 is separated from the trapezoidal slot.

[0060] When disassembling the tester body 3, press down the pressing plate 26, and the pressing plate 26 drives the two side plates 15 to move in opposite directions through the transmission assembly, so that the trapezoidal pin block 23 is separated from the trapezoidal slot. After that, the tester body 3 can be taken out from the installation cavity, and the disassembly operation is simple and quick. When installing the tester body 3 in the housing 1, place the tester body 3 in the installation cavity and align the trapezoidal pin block 23 with the trapezoidal slot in the Z direction, press down the tester body 3 to make the two side plates 15 move in opposite directions, and when the trapezoidal pin block 23 and the trapezoidal slot are aligned in the X direction, the two side plates 15 can move toward each other under the elastic force of the elastic buffer assembly, so that the trapezoidal pin block 23 and the trapezoidal slot are completely engaged, and the tester body 3 is limited in the installation cavity. That is, when installing the tester body 3, you only need to press down the tester body 3, and the operation is simple and quick.

[0061] like Figure 6 and Figure 7 As shown, the bottom wall of the installation cavity is provided with a shock absorbing assembly, which is used to support the tester body 3. During the use of the photoelectric tester, the tester body 3 is buffered and protected by the shock absorbing assembly at the bottom and the elastic buffer assembly at the side to prevent the tester body 3 from being damaged by rigid collision with the wall of the installation cavity.

[0062] like Figure 1 , Figure 2 as well as Figure 3 As shown, the locking assembly further includes a rectangular plate 5, which is disposed on the housing 1 and is provided with a rectangular cavity 510, and a knob 7 is rotatably disposed on the outer wall of the rectangular plate 5. The linkage assembly further includes a rotating shaft 6 located in the rectangular cavity 510, a bidirectional protrusion 8, a first connecting rod 13, a partition plate 9, and a reset unit.

[0063] Specifically, the rotating shaft 6 is coaxially connected with the knob 7; the bidirectional protrusion 8 is rotatably arranged on the cavity wall of the rectangular cavity 510 and connected to the rotating shaft 6. A first connecting rod 13 is rotatably connected to the opposite sides of the bidirectional protrusion 8, and the end of the first connecting rod 13 away from the bidirectional protrusion 8 is rotatably connected to the corresponding pin 10. Two partitions 9 are fixedly arranged at intervals in the rectangular cavity 510, and the two partitions 9 extend along the Z direction, and the partitions 9 are located on the side of the first connecting rod 13 away from the bidirectional protrusion 8. The pin 10 is movably inserted into the corresponding partition 9 along the X direction. A fixing ring 11 is circumferentially arranged on the pin 10, and the reset unit is sleeved on the pin 10 and is located between the partition 9 and the fixing ring 11.

[0064] When the operator turns the knob 7, the knob 7 can drive the two-way projection 8 to rotate through the rotating shaft 6. When the two-way projection 8 rotates, the two first connecting rods 13 drive the two pins 10 to move toward each other along the X direction. During this period, the two pins 10 slide and cooperate with the corresponding partitions 9. The first connecting rod 13 rotates relative to the two-way projection 8 and the pins 10. When the two pins 10 move toward each other along the X direction, the fixing ring 11 moves accordingly and compresses the reset unit, so that the reset unit accumulates potential energy. When the pin 10 moves to be separated from the pin groove, the tester body 3 can be disassembled.

[0065] When the knob 7 is released, the reset unit releases potential energy and pushes the two pins 10 to move away from each other through the fixing ring 11. When the two pins 10 move away from each other, the first connecting rod 13 drives the two-way protrusion 8 to rotate in the opposite direction. The two-way protrusion 8 then drives the knob 7 to rotate in the opposite direction through the rotating shaft 6 until it is reset.

[0066] In this embodiment, the two first connecting rods 13 , the two pins 10 , and the two partitions 9 on both sides of the bidirectional protrusion 8 are all symmetrical with respect to the axis of the rotating shaft 6 .

[0067] Furthermore, in this embodiment, the connecting ends of the bidirectional projection 8 and the two first connecting rods 13 are symmetrical about the axis of the rotating shaft 6, so that when the bidirectional projection 8 drives the pin 10 to move, the moving strokes of the two pins 10 are consistent.

[0068] like Figure 3 As shown, optionally, the reset unit includes a reset spring 12. One end of the reset spring 12 is fixedly mounted on the side of the fixing ring 11, and the other end of the reset spring 12 is fixedly mounted on the side of the partition 9. By providing the reset spring 12, after the knob 7 is loosened, the pin 10 can be reset by the elastic action of the reset spring 12.

[0069] like Figure 3 As shown, a protective pad 14 is provided in each of the two pin grooves, and the protective pad 14 is used to contact the end of the pin 10. By providing the protective pad 14, the pin 10 can be protected when the pin 10 is reset, and it can be prevented from colliding with the inner wall of the pin groove and causing damage. The protective pad 14 is preferably a rubber pad.

[0070] like Figure 4 and Figure 5 As shown, the transmission assembly includes a telescopic sleeve 27 , a fixing column 28 , an elastic unit, a square block 30 , a second connecting rod 31 and a sliding block 25 .

[0071] Specifically, the telescopic sleeve 27 is connected to the bottom of the pressing plate 26 and movably penetrates the bottom wall of the pressing groove 110, and the lower end of the telescopic sleeve 27 extends into the transmission cavity 120. The fixed column 28 is fixedly arranged on the cavity wall of the transmission cavity 120, and the upper end of the fixed column 28 extends into the telescopic sleeve 27 and is slidably matched with the telescopic sleeve 27. The elastic unit is arranged in the telescopic sleeve 27 and is located between the top inner wall of the telescopic sleeve 27 and the top surface of the fixed column 28. The square block 30 is fixedly sleeved outside the telescopic sleeve 27, and the opposite sides of the square block 30 are rotatably connected to a second connecting rod 31, and each second connecting rod 31 is rotatably connected to a slider 25 at one end away from the square block 30. The slider 25 can slide along the X direction in the transmission cavity 120.

[0072] When the operator presses the pressing plate 26 downward, the telescopic sleeve 27 and the square block 30 can move downward with the push of the pressing plate 26. The square block 30 drives the two sliders 25 to move in opposite directions through the two second connecting rods 31. When the two sliders 25 move in opposite directions, they push the two side plates 15 to move in opposite directions, so that the trapezoidal slot is separated from the trapezoidal pin block 23. During this period, the telescopic sleeve 27 compresses the elastic unit, the elastic unit accumulates elastic potential energy, and the second connecting rod 31 rotates relative to the square block 30 and the slider 25. After the tester body 3 is disassembled, the pressing plate 26 is released, and the elastic unit releases the elastic potential energy to drive the telescopic sleeve 27 and the pressing plate 26 to move up and reset. At the same time, the two sliders 25 move toward each other under the drive of the square block 30, and no longer push the side plate 15. The side plate 15 moves back to its original position under the elastic force of the elastic buffer assembly.

[0073] Further, see Figure 4 and Figure 5 , the housing 1 is provided with a slide groove 130 on both sides of the transmission cavity 120, and the side plate 15 is provided with a connecting block 24, which is slidably arranged in the slide groove 130 along the X direction, and the connecting block 24 is connected to the slider 25. When the two sliders 25 move in opposite directions along the X direction, the slider 25 pushes the connecting block 24 to move the side plate 15; when the side plate 15 moves under the elastic force of the elastic buffer assembly, the side plate 15 can push the two sliders 25 to move toward each other through the connecting block 24. That is, the elastic unit and the elastic buffer assembly both provide a force to reset the transmission assembly. The setting of the slide groove 130 provides guidance for the movement of the side plate 15 along the X direction to prevent the side plate 15 from moving skewed.

[0074] In this embodiment, a pressing groove 110 and a transmission cavity 120 are provided at both ends of the outer shell 1 along the Y direction, a pressing plate 26 is provided in each pressing groove 110, and the above-mentioned transmission component is provided in each transmission cavity 120. Corresponding to both ends of each side plate 15 along the Y direction, there is a slider 25 for pushing it to move, thereby ensuring the movement stability of the side plate 15 and preventing the side plate 15 from moving deflected.

[0075] Optionally, the elastic unit includes a pressing spring 29, one end of which is fixedly mounted on the top of the fixing column 28, and the other end of which is fixedly mounted on the top inner wall of the telescopic sleeve 27. By providing the pressing spring 29, when the pressing plate 26 is released, the elastic action of the pressing spring 29 can drive the pressing plate 26 to achieve a reset function.

[0076] Alternatively, see Figure 6 and Figure 7 The elastic buffer component includes a damping telescopic sleeve 16 , a damping telescopic rod 17 and a compression spring 18 .

[0077] Specifically, the damping telescopic sleeve 16 is embedded in the side plate 15; one end of the damping telescopic rod 17 is connected to the cavity wall of the installation cavity, and the other end of the damping telescopic rod 17 extends into the damping telescopic sleeve 16 and is slidably matched with the damping telescopic sleeve 16; the compression spring 18 is arranged in the damping telescopic sleeve 16 and is located between the inner bottom wall of the damping telescopic sleeve 16 and the end face of the damping telescopic rod 17. When the side plate 15 moves, the damping telescopic sleeve 16 slides relative to the damping telescopic rod 17, and the compression spring 18 inside the damping telescopic sleeve 16 deforms adaptively. The two side plates 15 can move toward each other under the elastic force of the compression spring 18, so that the trapezoidal slot is engaged with the trapezoidal pin block 23.

[0078] Alternatively, see Figure 6 and Figure 7 The shock absorbing assembly includes a shock absorbing pad 21, a base plate 20 and a plurality of shock absorbing springs 19.

[0079] Specifically, the bottom wall of the installation cavity is provided with a plurality of circular grooves, and the bottom ends of the plurality of shock absorbing springs 19 are installed in the plurality of circular grooves in a one-to-one correspondence; the bottom plate 20 is installed on the top ends of the plurality of shock absorbing springs 19; the shock absorbing pad 21 is arranged on the side of the bottom plate 20 facing away from the shock absorbing spring 19, and the shock absorbing pad 21 is used to contact the tester body 3. The arrangement of the shock absorbing spring 19 can play a good shock absorbing function when installing the tester body 3, and play a protective role for the tester body 3. The shock absorbing pad 21 contacts the tester body 3, and can avoid hard contact with the tester body 3 and damage to the tester body 3.

[0080] See also Figure 5 , the two side panels 15 are provided with guide grooves 22 on the sides facing each other, and the guide grooves 22 are located above the trapezoidal slots and communicated with the trapezoidal slots. In this embodiment, two trapezoidal slots are provided on each side panel 15, and a guide groove 22 is provided above each trapezoidal slot. The trapezoidal pin block 23 can be inserted into the trapezoidal slot along the guide grooves 22. The guide grooves 22 are used to guide the movement of the trapezoidal pin block 23 inserted into the trapezoidal slots. The guide grooves 22 can be observed when the outer cover 2 is opened. When installing the tester body 3, it is only necessary to align the trapezoidal pin block 23 with the guide grooves 22 in the Z direction.

[0081] See also Figure 5 The side of the trapezoidal pin block 23 facing away from the tester body 3 is a guiding slope, which gradually inclines from top to bottom toward the direction close to the tester body 3, so that the lower end of the trapezoidal pin block 23 can be smoothly inserted into the corresponding guide groove 22, and then smoothly inserted into the corresponding trapezoidal slot.

[0082] In this embodiment, a hinge is provided on the outer cover 2, and the outer cover 2 is rotatably connected to the outer shell 1 through the hinge to cover the cavity opening of the installation cavity. The fixing block 4 and the hinge are respectively arranged at both ends of the outer cover 2 along the Y direction.

[0083] This embodiment also provides a method for using a photoelectric tester, which is applied to the photoelectric tester as described above. The method for using the photoelectric tester includes the following steps: unlocking the outer cover 2, locking the outer cover 2, disassembling the tester body 3, and installing the tester body 3.

[0084] The step of unlocking the outer cover 2 includes: rotating the knob 7 along a first direction, and the knob 7 drives the two pins 10 to move toward each other through a linkage assembly, so that the pins 10 are disengaged from the corresponding pin grooves, thereby releasing the lock of the outer cover 2 on the housing 1.

[0085] The step of locking the outer cover 2 includes: driving the two pins 10 to move in opposite directions, so that the two pins 10 are inserted into the corresponding pin grooves, and the outer cover 2 is locked and fixed on the housing 1. Specifically in this embodiment, the two pins 10 are moved in opposite directions by the elastic force of the reset spring 12, and the two pins 10 then drive the knob 7 to rotate in the second direction through the first connecting rod 13, the two-way protrusion 8 and the rotating shaft 6. The second direction is opposite to the first direction (for example, one is clockwise and the other is counterclockwise).

[0086] The steps of disassembling the tester body 3 include: pressing down the pressing plate 26, which drives the two side plates 15 to move away from each other through the transmission assembly to separate the trapezoidal pin block 23 from the trapezoidal slot, and then taking out the tester body 3 from the installation cavity.

[0087] The steps of installing the tester body 3 include: placing the tester body 3 in the installation cavity and aligning the trapezoidal pin block 23 with the trapezoidal slot in the Z direction, and pressing down the tester body 3 to complete the engagement of the trapezoidal pin block 23 with the trapezoidal slot.

[0088] In summary, the use process of the photoelectric tester provided in this embodiment is roughly as follows:

[0089] When in use, first turn the knob 7, which in turn drives the rotating shaft 6 and the bidirectional projection 8 to rotate synchronously, and drives the two pins 10 to move toward each other under the action of the two first connecting rods 13, so that the two pins 10 are released from the limit of the two pin grooves, and then open the outer cover 2, start the tester body 3 to test. After opening the outer cover 2, the knob 7 can be loosened, and the knob 7 is reset under the action of the reset spring 12 (not plugged into the pin groove).

[0090] After use, the knob 7 is turned to drive the two pins 10 to move toward each other to avoid interference between the pins 10 and the fixing block 4. Then, the outer cover 2 is closed, and the knob 7 is loosened to drive the two pins 10 to move away from each other under the action of the two return springs 12 to lock and fix the outer cover 2.

[0091] When the tester body 3 is hit, the damping telescopic sleeves 16, the damping telescopic rods 17 and the compression springs 18 on both sides jointly achieve side shock absorption, and the shock absorbing springs 19 at the bottom achieve bottom shock absorption, thereby protecting the tester body 3 and preventing it from being damaged by collision.

[0092] When the tester body 3 needs to be disassembled, the two pressing plates 26 are pressed down, and the two pressing plates 26 drive the two telescopic sleeves 27 to move downward, and then drive the four sliders 25 to move away from each other under the action of the four second connecting rods 31, and the four sliders 25 push the four connecting blocks 24 to move away from each other in a one-to-one correspondence, and drive the two side plates 15 to move away from each other under the action of the four connecting blocks 24, thereby releasing the limitations of the four trapezoidal slots and the four trapezoidal pin blocks 23, and realizing the quick disassembly function of the tester body 3.

[0093] When the tester body 3 needs to be installed, it is only necessary to align the four trapezoidal pin blocks 23 with the four guide grooves 22, press the tester body 3 downward, and the tester body 3 squeezes the two side plates 15 to move away from each other. When the four trapezoidal pin blocks 23 and the four guide grooves 22 are facing each other in the X direction, the compression spring 18 releases the elastic force to drive the two side plates 15 to reset, thereby realizing the connection between the four trapezoidal pin blocks 23 and the four trapezoidal slots.
