Description

Technical Field

[0001] This invention relates to reliability testing technology, specifically to reliability testing technology for the safety cap of a horizontal spray type tear gas sprayer. Background Technology

[0002] As one of the essential pieces of equipment for police officers, tear gas sprayers have stringent requirements regarding their performance and reliability.

[0003] In August 2018, the Ministry of Public Security of the People's Republic of China issued public security industry standards for police single-officer equipment (five categories of products). Among them, the standard "GA884-2018 Police Single-Officer Equipment Tear Gas Sprayer" involves the reliability test of the safety cover of the tear gas sprayer. It requires opening and closing the safety cover of the horizontal spray type tear gas sprayer 100 times to test whether the safety cover and the pressure handle can work normally.

[0004] The testing process requires unscrewing the safety cap and pushing the handle horizontally back. Current testing procedures are generally performed manually by the testing personnel. According to the standard, the safety cap of the horizontal spray tear gas sprayer must be opened and closed at least 100 times, which is repetitive mechanical labor. Manual counting is prone to errors. Furthermore, the testing process is inherently dangerous. If the safety cap is unreliable or if the handle is accidentally pressed down during the horizontal push-back test, tear gas will be sprayed, causing severe irritation and discomfort to the testing personnel.

[0005] Currently, there is no device for testing the reliability of the safety cap of a horizontally spraying tear gas sprayer. Therefore, providing a testing device that can effectively test the reliability of the safety cap of a horizontally spraying tear gas sprayer is a problem that urgently needs to be solved in this field. Summary of the Invention

[0006] To address the problems with existing methods for manually verifying the reliability of the safety caps on horizontally spraying tear gas sprayers, a testing device is needed that can effectively verify the reliability of the safety caps on horizontally spraying tear gas sprayers.

[0007] Therefore, the purpose of this invention is to provide a reliability testing device for the safety cap of a horizontally spraying tear gas sprayer. Based on this reliability testing device, this invention also provides a reliability testing method for the safety cap of a horizontally spraying tear gas sprayer, thereby achieving automatic testing of the safety cap of the horizontally spraying tear gas sprayer, reducing the workload of test personnel, and effectively protecting the safety of test personnel.

[0008] To achieve the above objectives, the present invention provides a reliability testing device for the safety cap of a horizontal spray type tear gas sprayer, comprising:

[0009] A sample fixing assembly is used to fix the horizontal spray tear gas sprayer to be tested, and to limit the movement and rotation of the horizontal spray tear gas sprayer to be tested;

[0010] A safety cap rotating assembly is provided relative to a sample fixing assembly. It can be fitted onto the safety cap of the horizontal spray tear gas sprayer to be tested, which is fixed by the sample fixing assembly, and drive the safety cap to rotate.

[0011] The pressure handle pushing assembly is set relative to the sample fixing assembly. The pressure handle pushing assembly cooperates with the safety cover rotating assembly. When the safety cover rotating assembly drives the safety cover on the horizontal spray tear gas sprayer to be tested to rotate and close, it synchronously drives the pressure handle on the horizontal spray tear gas sprayer to be tested, so that the pressure handle is pushed back and retracted.

[0012] A drive assembly that drives the safety cover rotation assembly and the pressure handle push-in assembly to operate;

[0013] The control component controls the connected drive component and counts the number of times the safety cover rotation component drives the safety cover of the horizontal spray tear gas sprayer under test to open and close.

[0014] Furthermore, the sample fixing assembly includes a base plate, a vertical rod, and a sample fixing quick-release clamp, wherein the vertical rod is disposed on the base plate and the sample fixing quick-release clamp is disposed on the vertical rod.

[0015] Furthermore, the sample fixing assembly also includes a support ring, which is disposed on the upright and cooperates with the safety cover rotating assembly.

[0016] Furthermore, the sample fixing quick-release chuck mainly includes two semi-circular ring clamping bodies and a fastening assembly. One end of the two semi-circular ring clamping bodies is hinged, and the other end is connected through the fastening assembly.

[0017] Furthermore, the drive component synchronously drives the safety cover rotation component and the pressure handle push-in component to operate.

[0018] Furthermore, the safety cover rotating assembly includes a safety cover sleeve and a first gear disposed on the safety cover sleeve. The safety cover sleeve can be fitted onto the safety cover of the horizontal spray tear gas sprayer to be tested, and can rotate the safety cover between the open and closed states under the drive of the drive assembly. When the safety cover is rotated to the open state, the pressure handle on the horizontal spray tear gas sprayer can be normally ejected.

[0019] Furthermore, the pressure handle pushing assembly includes a second gear and a cam. The second gear meshes with the first gear in the safety cover rotating assembly and drives the cam to rotate. The cam is configured to correspond to the safety cover sleeve in the safety cover rotating assembly. When the safety cover on the horizontal spray tear gas sprayer to be tested is rotated and closed, the pressure handle on the horizontal spray tear gas sprayer to be tested is simultaneously driven, so that the pressure handle is pushed back in.

[0020] Furthermore, the driving component is a rotating electromagnet, which rotates in a first direction when energized and rotates in a second direction when de-energized.

[0021] To achieve the above objectives, the present invention provides a reliability testing method for the safety cap of a horizontal spray type tear gas sprayer, comprising:

[0022] Insert the safety cap on the horizontal spray tear gas sprayer to be tested into the safety cap rotating assembly, and fix the horizontal spray tear gas sprayer to be tested.

[0023] When the controller is activated, the drive assembly drives the safety cover rotation assembly to rotate the safety cover between the open and closed states. When the safety cover is rotated to the open state, the pressure handle on the horizontal spray tear gas sprayer pops out normally. When the safety cover rotation assembly drives the safety cover to rotate and close, it synchronously drives the pressure handle on the horizontal spray tear gas sprayer under test, causing the pressure handle to retract.

[0024] The controller counts the number of times the safety cover of the horizontal spray tear gas sprayer to be tested is opened and closed, and stops the testing operation after the required number of tests is reached.

[0025] Furthermore, the controller controls the driving direction of the drive component by energizing and de-energizing it, so as to rotate the safety cover between the open and closed states; and records the number of times the energizing and de-energizing operations are completed.

[0026] The solution provided by this invention can replace manual inspection of the safety cap of horizontal spray tear gas sprayers, effectively reducing the repetitive mechanical labor of testing personnel and effectively protecting the safety of testing personnel. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Figure 1 This is an example diagram of the overall structure of the reliability testing device for the safety cap of the horizontal spray type tear gas sprayer in an embodiment of the present invention.

[0029] Figure 2 This is a structural example diagram of the sample fixing assembly in an embodiment of the present invention;

[0030] Figure 3 for Figure 2 The diagram shows an example of the structure of the sample fixing quick-release chuck in the sample fixing assembly. Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0032] The standard for reliability testing of the safety cover of a horizontal spray tear gas sprayer stipulates that the safety cover of the horizontal spray tear gas sprayer should be opened and closed, and the pressure handle should be observed to pop out and reset normally. This action should be repeated 100 times to test whether the safety cover and pressure handle can work normally.

[0033] Accordingly, this example provides a reliability testing device for the safety cap of a horizontal spray tear gas sprayer, which can replace manual testing of the safety cap reliability of the horizontal spray tear gas sprayer.

[0034] See Figure 1 The diagram shows an example of the composition of a reliability testing device for the safety cap of a horizontal spray tear gas sprayer, as given in this example.

[0035] Combination Figure 1 As shown, the reliability testing device 100 is mainly composed of a sample fixing assembly 110, a safety cover rotating assembly 120, a pressure handle pushing assembly 130, a drive assembly 140, and a control assembly 150 working together.

[0036] The sample fixing component 110 is used to fix the horizontal spray tear gas sprayer to be tested, and to limit the movement and rotation of the horizontal spray tear gas sprayer to be tested.

[0037] As an example, the sample fixing assembly 110 fixes the horizontal spray tear gas spray to be tested in a positive vertical position, restricts the vertical horizontal spray tear gas spray to be tested in the axial and radial directions, and restricts the rotation of the vertical horizontal spray tear gas spray to be tested, so that the horizontal spray tear gas spray to be tested is completely vertically fixed in the sample fixing assembly 110.

[0038] The safety cover rotating assembly 120 is positioned relative to the sample fixing assembly 110 and can be fitted onto the safety cover of the horizontal spray tear gas sprayer to be tested, which is fixed by the sample fixing assembly 110. It can also drive the safety cover to rotate between the open and closed states. When the safety cover is rotated to the open state, the pressure handle on the horizontal spray tear gas sprayer can be ejected normally.

[0039] Based on the above example scheme, the safety cap rotating assembly 120 can be set above the sample fixing assembly 110, thereby driving the rotation of the safety cap on the vertically set horizontal spray tear gas sprayer to be tested in the sample fixing assembly 110.

[0040] The pressure handle push-in assembly 130 is positioned relative to the safety cover rotation assembly 120 to cooperate with the safety cover rotation assembly. When the safety cover rotation assembly 120 drives the safety cover on the horizontal spray tear gas sprayer under test to rotate and close, it synchronously drives the pressure handle that pops out on the horizontal spray tear gas sprayer under test, so that the pressure handle is pushed back in, so that the safety cover rotation assembly 120 can drive the safety cover on the horizontal spray tear gas sprayer under test to rotate and close.

[0041] The drive assembly 140 is used to drive the safety cover rotation assembly 120 and the pressure handle push assembly 130 to move, and to drive the two to cooperate with each other.

[0042] The control component 150 is used to control the working state of the connection drive component 140 and to count the number of times the safety cover rotation component drives the safety cover of the horizontal spray tear gas sprayer under test to complete the opening and closing operation.

[0043] Based on this, this example also adds a cover 160 to the reliability testing device 100, which forms a sealed testing space to place the sample fixing assembly 110, the safety cover rotating assembly 120, and the pressure handle pushing assembly 130 therein, so as to ensure the safety of the testing process.

[0044] Furthermore, in this example, the drive component 140 and the control component 150 are placed outside the housing 160, which facilitates control and maintenance during device operation. In case of device failure, the control component can be stopped immediately, thus ensuring the reliability of the entire device operation.

[0045] The following example illustrates the specific implementation process of the above solution.

[0046] In its specific implementation, this example takes into account the cylindrical structural characteristics of the horizontal spray tear gas sprayer and adopts... Figure 2 The sample fixing assembly 110 shown is used to provide stable fixation for the horizontal spray tear gas sprayer.

[0047] Combination Figure 2 As shown, the sample fixing assembly 110 is a support frame structure, mainly including a base plate 111, a vertical rod 112, a sample fixing quick-release clamp 113, a support ring 114, and a top plate 115.

[0048] The base plate 111 serves as the base of the entire sample fixing assembly 110. To ensure reliability, it adopts a flat plate structure, and the flat plate 111 fits into the inner cavity of the cover 160.

[0049] The upright pole 112 is vertically mounted on the base plate 111. The specific configuration of the upright pole 112 is not limited here, as long as it provides stable and reliable support. Furthermore, the height of the upright pole 112 corresponds to the height of the horizontal spray tear gas sprayer to be tested.

[0050] Meanwhile, a top plate 115 is provided at the top of the upright 112. This top plate 115 serves as a platform for placing other components in this device, and a flat plate structure is preferably adopted to ensure reliability. The flat plate 115 is arranged parallel to the bottom plate 111, and its surface serves as a mounting surface for placing other components.

[0051] The sample fixing quick-release clamp 113 and the support ring 114 are respectively set on the upright 112 for fixing the horizontal spray tear gas sprayer to be tested.

[0052] The support ring 114 is located above the sample fixing quick-release clamp 113, which can support and limit the safety cover rotating assembly 120 located below the top plate 115, ensuring the reliability of the rotating assembly's movement. Furthermore, the support ring 114 can also limit the upper end of the horizontal spray tear gas sprayer to be tested.

[0053] As shown in the figure, the support ring 114 here has a stepped structure 114a on its inner side to cooperate with the safety cover rotating assembly 120, to limit the safety cover rotating assembly 120 and prevent it from falling out, thereby providing stable support and limiting the safety cover rotating assembly 120.

[0054] The sample fixing quick-release clamp 113 is used to clamp and secure the canister of the horizontal spray type tear gas sprayer. For example, such as... Figure 3 As shown, the sample fixing quick-release chuck 113 in this example mainly consists of two semi-circular ring clamping bodies 113a, a hinge bolt 113b, a pin 113c, and a wing nut 113d.

[0055] One end of the two semi-circular ring clamping bodies 113a is hinged, allowing the two semi-circular ring clamping bodies 113a to rotate relative to each other; the other end of the two semi-circular ring clamping bodies 113a is detachably connected by a fastening assembly consisting of a hinge bolt 113b, a pin 113c, and a wing nut 113d.

[0056] The sample fixing quick-release chuck 113, with its annular clamping body, is fixedly connected to the upright 112 via a connecting short rod, achieving a horizontal setting on the upright 112. During operation, simply loosening the wing nut and moving the hinge bolt outwards opens the quick-release chuck 113, allowing the installation of the horizontal spray tear gas sprayer to be tested.

[0057] This example addresses the structural characteristics of the safety cap on a horizontal spray tear gas sprayer by employing a corresponding safety cap sleeve 121 and a first gear 122 to construct a safety cap rotating assembly 120. The safety cap rotating assembly 120 is controlled by a drive assembly 140 and can rotate relative to the sample fixing quick-release clamp 113 under the drive of the drive assembly 140.

[0058] The safety cap sleeve 121 adopts an internal toothed sleeve structure, which can be integrally fitted onto the safety cap; and the tooth shape of the safety cap sleeve matches the tooth shape of the edge of the tear gas spray safety cap, which can drive the safety cap to rotate synchronously with it. Furthermore, in order to ensure that the pressure handle on the horizontal spray type tear gas spray can pop out when the safety cap is rotated to the open state, this example also has a corresponding notch on the safety cap sleeve 121 corresponding to the notch on the safety cap, so as to allow the pressure handle on the horizontal spray type tear gas spray to pop out normally.

[0059] The safety cover sleeve 121 with this structure is set on the bottom surface of the top plate 115 relative to the sample fixing quick-release clamp 113, with the open end facing the sample fixing quick-release clamp 113, and cooperates with the support ring 114, which provides support and limit.

[0060] The safety cap sleeve 121 is positioned to correspond to the height of the horizontal spray tear gas sprayer, ensuring that when the horizontal spray tear gas sprayer is vertically fixed in the sample fixing assembly 110 via the sample fixing quick-release clamp 113, its safety cap is precisely inserted into the safety cap sleeve 121. Thus, by rotating the safety cap sleeve 121, the safety cap on the horizontal spray tear gas sprayer can be rotated, opening and closing it. Because the safety cap sleeve 121 has a notch that mates with the safety cap, the pressure handle on the horizontal spray tear gas sprayer can pop out normally when the safety cap is rotated to the open position.

[0061] Furthermore, the first gear 122 is disposed on the safety cover sleeve 121 to drive the safety cover sleeve 121 to rotate synchronously and to drive the pressure handle pushing assembly 130 synchronously, thereby realizing the synchronous driving of the safety cover rotation assembly 120 and the pressure handle pushing assembly 130 through a driving assembly 140.

[0062] The first gear 122 is specifically mounted on the safety cover sleeve 121, and the specific mounting location can be determined according to actual needs. For example, the first gear 122 can be fixedly mounted on the top of the safety cover sleeve 121 by welding.

[0063] To cooperate with the aforementioned safety cover rotating assembly 120, the pressure handle pushing assembly 130 in this example is mainly composed of a pin 131, a second gear 132, and a cam 133 working together.

[0064] The second gear 132 is located below the top plate 115 via a pin 131 and meshes with the first gear 122, so that the pin 131 can be rotated synchronously with the drive of the first gear 122.

[0065] Cam 133 is correspondingly set at the lower end of pin 131 and cooperates with the safety cover sleeve 121 on the safety cover rotating assembly 120. Cam 133 can rotate synchronously with pin 131 and drive the pressure handle that pops out on the horizontal spray tear gas sprayer to be tested during the rotation process, so that the pressure handle is pressed back into the horizontal spray tear gas sprayer.

[0066] When the safety cover is rotated open, the pressure handle on the horizontal spray tear gas sprayer pops out of the cover, at which point the cover cannot be rotated to close. The safety cover can only be rotated to close when the pressure handle is pushed back into the horizontal spray tear gas sprayer.

[0067] This example uses the meshing design of the second gear 132 and the first gear 122, combined with the design of the cam 133, so that the cam 133 can be matched with the safety cover sleeve 121 and rotate synchronously to complete the rotation opening and rotation closing of the safety cover on the horizontal spray tear gas sprayer.

[0068] Specifically, when the safety cover sleeve 121 drives the safety cover to rotate to the open state, the pressure handle pops out normally; during this process, based on the synchronous drive of the meshing gears, the cam 133 will also rotate synchronously, at which time the cam 133 does not move any component.

[0069] When the safety cover sleeve 121 drives the safety cover to rotate and close, in the initial stage, the cam 133 will also rotate synchronously. During the rotation, the cam 133 abuts against the popped-out pressure handle and pushes the pressure handle in at the highest point of its stroke, pushing the pressure handle horizontally into the horizontal spray tear gas sprayer. After the safety cover sleeve 121 drives the safety cover to continue rotating (facing the closing direction) by a certain angle, the safety cover will abut against the pressure handle that has been pressed into the horizontal spray tear gas sprayer by the cam 133. During this process, the safety cover sleeve 121 synchronously drives the cam to continue rotating, which causes the cam to disengage from the pressure handle. At this time, the safety cover can continue to rotate to the end to achieve closure.

[0070] The specific configuration of cam 133 in this example is not limited here, as long as it can achieve the above-mentioned functions.

[0071] In this example, the drive assembly 140, which is the power component of the device, is preferably constructed using a rotating electromagnet. The corresponding safety cover sleeve 121 is disposed on the top plate 115, and the safety cover sleeve 121 in the drive safety cover rotation assembly 120 on the top plate 115 is used to drive the safety cover sleeve 121 and the first gear 122 to rotate.

[0072] Because the safety cover sleeve 121 needs to rotate back and forth within a certain angle to drive the safety cover inserted therein to rotate back and forth between the open and closed states.

[0073] Therefore, the rotating electromagnet in this example is a DC rotating electromagnet, and the DC rotating electromagnet is configured to rotate a certain angle when energized and to rotate and reset when de-energized.

[0074] Preferably, the DC rotary electromagnet can be a self-resetting rotary electromagnet, which provides the necessary restoring force to drive the safety cover and pressure handle back to their initial positions after power failure.

[0075] For example, the DC rotary electromagnet can be configured such that when energized, it drives the safety cover sleeve 121 to rotate in the direction of opening the safety cover, and the rotation angle is such that the safety cover sleeve 121 can drive the safety cover to rotate to the open state; when the DC rotary electromagnet is de-energized, it rotates in the opposite direction to reset, and then drives the safety cover sleeve 121 to rotate in the direction of closing the safety cover, and the rotation angle is such that the safety cover sleeve 121 can drive the safety cover to rotate to the closed state.

[0076] This DC rotary electromagnet design features a simple structure, stable and reliable performance, and ease of control, while also facilitating subsequent inspection and counting operations. Furthermore, it can be powered by dry-cell batteries located in the battery compartment, ensuring safety and reliability, and eliminating the need for an external power source or air supply.

[0077] When the DC rotary electromagnet is de-energized and rotates to reset, it needs to synchronously drive the cam 133 in the push-in assembly 130 to horizontally push the ejected push-in handle into the horizontal spray tear gas sprayer, so that the safety cover sleeve 121 can drive the safety cover to rotate and close normally. In this example, it is preferable that the rotation angle of the rotary electromagnet is greater than the opening angle of the tear gas sprayer safety cover. In this way, when the rotary electromagnet is de-energized and rotates to reset, it initially rotates a certain angle (the angle value is the angle value of the rotation angle of the rotary electromagnet being greater than the opening angle of the tear gas sprayer safety cover). During this process, the cam 133, driven by the rotary electromagnet (as described above), abuts against the ejected push-in handle and pushes the push-in handle in at the highest point of its stroke, horizontally pushing the push-in handle into the horizontal spray tear gas sprayer. Subsequently, the tear gas sprayer safety cover continues to rotate under the drive of the safety cover sleeve and covers the push-in handle.

[0078] Regarding the above-described scheme using a DC rotating electromagnet as the drive component 140, the control component 150 in this example is preferably constructed using a corresponding counting controller. This counting controller is mounted on the top plate 115, controls the connected DC rotating electromagnet, and is configured to control the energization and de-energization states of the DC rotating electromagnet. The counting controller counts the number of times the DC rotating electromagnet completes one energization and de-energization operation, thereby representing the number of times the safety cover is inspected.

[0079] As needed, the counting controller is also equipped with a corresponding display that can show the specific number of counts.

[0080] Finally, in this example, the housing 160 is preferably made of transparent plexiglass to form the overall housing of the device, without a bottom or top surface. This housing 160, with this structure, is placed between the top plate 115 and the bottom plate 111 of the sample fixing assembly 110, thereby housing the sample fixing assembly 110, the safety cap rotating assembly 120, and the pressure handle pushing assembly 130. This allows for convenient observation of the device's operating status and the display of the number of tests, while also ensuring the test device remains sealed, preventing injury to test personnel in the event of tear gas spray. Furthermore, during the test, test personnel can adjust the drive assembly 140 and the control assembly 150 located outside the housing 160 at any time, ensuring safe and reliable operation.

[0081] The reliability testing device 100 based on the above scheme can perform reliability testing of the safety cap of a horizontal spray tear gas sprayer, replacing manual testing. The following describes the implementation process of using this device to perform reliability testing of the safety cap of a horizontal spray tear gas sprayer.

[0082] Combination Figure 1 When using the reliability testing device 100 based on the above scheme, first lift the cover 160 upwards, and put the upper end of the sample to be tested (horizontal spray type tear gas sprayer) into the safety cover sleeve 121, so that the notch of the safety cover is consistent with the notch of the safety cover sleeve 121 (without affecting the protrusion of the pressure handle).

[0083] Then, use the sample fixing quick-release clamp 113 to fix the anti-slip ring on the outer can of the sample to be tested.

[0084] Next, pressing the power switch on the controller 150 energizes the rotating electromagnet 140, causing it to rotate to a fixed angle. Simultaneously, this rotation drives the first gear 122 and the safety cover sleeve 121 to rotate. The safety cover sleeve 121 then rotates the safety cover inserted within it, causing the safety cover of the horizontal spray tear gas sprayer to open, at which point the pressure handle pops out. During this process, the second gear 132, meshing with the first gear 122, rotates accordingly, driving the cam 133 to rotate.

[0085] Next, the controller 150 de-energizes the rotating electromagnet 140. After the rotating electromagnet 13 is de-energized, it rotates to its reset position, causing the first gear 122 and the safety cover sleeve 121 to rotate in the opposite direction. At the same time, the second gear 132 and the cam 133 rotate synchronously in the opposite direction. At this time, in the initial stage of directional rotation, the protrusion of the cam 133 pushes the spring-loaded pressure handle on the horizontal spray tear gas sprayer back horizontally. Afterward, the safety cover sleeve 121 drives the tear gas sprayer safety cover to continue rotating to a certain angle. The cam 133 continues to rotate synchronously, and its protrusion disengages from the horizontal spray tear gas sprayer pressure handle, allowing the tear gas sprayer safety cover to continue rotating to the end (the specific process is as described above, and will not be repeated here).

[0086] Finally, the controller counts and displays the number of times the rotating electromagnet 13 completes one power-on and power-off operation, and automatically terminates the test after displaying 100 times.

[0087] As can be seen from the above, the reliability testing device scheme for the safety cap of the horizontal spray tear gas sprayer presented in this example can effectively replace manual testing of the safety cap of the horizontal spray tear gas sprayer, effectively reducing the mechanical repetitive workload of the testing personnel.

[0088] Furthermore, this reliability testing device design incorporates a clever and innovative design of a pair of meshing gears and a cam. The cam pushes the pressure handle at the highest point of its stroke, and after the safety cover rotates a certain angle, the cam disengages from the pressure handle. The safety cover then continues to rotate to the bottom, achieving two-step operation that can be completed with a single input.

[0089] Furthermore, this reliability testing device uses a DC rotary electromagnet to control the rotation of the safety cover and the pushing in of the pressure handle. Combined with a counter, it can achieve the requirement of 100 tests. The structure is simple, the control method is straightforward, and the test speed and pushing force are uniform. It can also use dry batteries in the battery compartment as a power source, ensuring safety and reliability, and eliminating the need for an external power supply or air source connection.

[0090] Finally, this reliability testing device design adopts a transparent enclosure structure, which not only facilitates observation of the device's operating status and the display of the number of tests, but also ensures the closed state of the testing device, avoiding harm to test personnel in the event of tear gas spraying.

[0091] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
