Description

Technical Field

[0001] The present invention relates to law enforcement equipment, and in particular to a law enforcement recorder with a protective device. Background Art

[0002] In order to standardize law enforcement, enhance the fairness of law enforcement activities, fix evidence, and safeguard the legitimate rights and interests of law enforcement personnel, law enforcement personnel will wear law enforcement recorders to film and collect evidence during their daily law enforcement process.

[0003] Chinese patent CN 110165763 A discloses an automatically charging law enforcement recorder, including a shell, a law enforcement recorder body and a charging device. The shell includes a front shell made of a solar panel. The charging device includes a solar panel, a solar converter connected to the solar panel and a battery. The solar panel includes a rectangular front shell and two solar panels connected to the side of the law enforcement recorder body. The law enforcement recorder has the performance of automatically storing electricity, providing power to terminal equipment and saving costs, solving the technical defect of the inability to automatically charge in the existing technical problems.

[0004] However, there are still some problems in this technical solution. In the actual law enforcement process, such as when traffic police maintain traffic order, police officers mediate disputes, and customs officers inspect goods, some people often refuse to cooperate with law enforcement, push law enforcement officers, or even violently resist the law, tearing off and breaking the law enforcement recorder. In order to facilitate wearing, existing law enforcement recorders are generally fixed directly on the epaulettes with simple plastic clips, which are easy to be torn off. In addition, the recorder has no effective protection device after falling, which can easily cause key components such as the lens and battery in the recorder to be damaged, increasing the loss and use cost of the recorder. The above technical solution has not effectively solved these problems. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology and provide a law enforcement recorder with a protective device. By arranging a pop-up elastic plate in the recorder, when an illegal person pulls the recorder, the elastic plate pops outward, causing impact on the illegal person's hand, causing pain and disturbance, causing him to let go, and at the same time providing buffering protection for the fallen recorder. By arranging a sliding slide and a card plate, after the slide drives the elastic plate to extend outward, the card plate clamps the slide, preventing the elastic plate from being completely squeezed into the recorder after colliding with the ground.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A law enforcement recorder with a protective device, comprising a recorder body and further comprising:

[0008] A retractable protective portion installed inside the recorder body, the protective portion including an elastic plate for buffering and protecting the recorder body;

[0009] a control unit for controlling the extension and retraction state of the protection unit, the control unit comprising a sealing plate that blocks the protection unit;

[0010] A mounting portion provided on the recorder body, the mounting portion including a clamping member;

[0011] a detection portion provided on the mounting portion for detecting a stress state of the recorder body, the detection portion comprising a pressure plate mounted on the clamping member; and

[0012] A transmission unit connects the detection unit and the control unit.

[0013] Specifically, the elastic plate is an elastic plastic plate or an elastic metal plate that can be bent, deformed and automatically reset; an open groove for placing the elastic plate is opened on the recorder body; a lens assembly and a battery assembly are provided in the recorder body. Depending on the specific usage, the elastic plate can be installed near the lens and battery to provide buffering protection for these key structures.

[0014] In the initial state, the protective plate is retracted inside the recorder body to prevent the protective plate from being extended outward and easily obstructing the camera shooting or pressing against the body of the law enforcement officer, causing discomfort. The sealing plate blocks the opening slot to play a sealing and protective role, preventing external debris from entering the recorder body.

[0015] Before enforcing the law, the staff clamps the clamp on the epaulette to fix the recorder body on the body of the law enforcement officer. The clamp can also be adjusted according to the specific equipment worn by the law enforcement officer and installed on other devices. When someone tries to illegally tear off the recorder body, they will pull the recorder body hard, causing the pressure plate on the recorder body to be subjected to excessive pressure. At this time, the control unit starts to open the sealing plate, causing the elastic plate to pop outward. The elastic plate extending to the outside of the recorder body can cause impact on the hand of the illegal person, causing him to feel pain and disturbance, thereby loosening the recorder body. It can also serve as a buffer protection for the recorder body when the recorder is torn off by the illegal person and is still on the ground, so as to prevent key structures such as the lens and battery in the recorder body from being damaged.

[0016] As a preferred embodiment, the protection part further includes:

[0017] a slide seat slidably mounted inside the recorder body, the elastic plate being mounted on the slide seat; and

[0018] A sleeve is slidably mounted on the slide seat and is used to constrain the elastic plate.

[0019] As a preferred embodiment, the elastic plate includes:

[0020] a straight edge section fixedly mounted on the slide; and

[0021] A curved section is provided at the end of the straight edge section and can extend outward, and the sleeve is sleeved on the outside of the curved section.

[0022] Specifically, the straight edge section is fixedly mounted on a slide, a compression spring is mounted on the slide, and a tension spring is mounted on the sleeve. In the initial state, the slide and the sleeve are both retracted inside the recorder body, and the curved section is compressed inside the sleeve. At this time, the compression spring is in a compressed state, and the tension spring is in a stretched state. When the elastic plate extends to the outside of the recorder body, the curved section extends from the sleeve and expands outward.

[0023] In the initial state, the bent section of the elastic plate is straightened by the sleeve so that the elastic plate can be retracted into the interior of the recorder body and the elastic plate can be smoothly extended from the recorder body;

[0024] When the elastic plate extends to the outside of the recorder body, the bent section separates from the sleeve and begins to expand outward. In this way, when the recorder body falls to the ground, the contact area between the elastic plate and the ground can be increased, allowing the elastic plate to contact the ground more easily and better protect the recorder body.

[0025] As another preferred embodiment, the control unit further includes:

[0026] a guide plate inserted into the sleeve, the guide plate being fixed on the slide; and

[0027] A positioning rod is provided on the sealing plate and is used to fix the sleeve on the guide plate.

[0028] Specifically, both the sleeve and the positioning rod are provided with positioning grooves corresponding to the positioning rod; the guide plate can slide on the slide seat through the positioning rod.

[0029] As a preference, an edge plate is provided on the outer side of the sleeve, and a step for clamping the edge plate is provided inside the recorder body.

[0030] Specifically, when the protective portion is installed inside the recorder body, the slide is moved along the negative direction of the Z axis. After the slide and the sleeve move rightward for a certain distance, the edge plate on the sleeve is blocked by the step. Therefore, the sleeve cannot move rightward any further, while the slide can continue to move rightward. As a result, the sleeve and the slide are relatively displaced. The sleeve moving leftward relative to the slide can straighten the bent section on the elastic plate. In this process, the tension spring on the sleeve is also stretched.

[0031] After the slide moves to the rightmost end, the sealing plate is started to move downward and block the opening groove. At this time, the positioning rod on the sealing plate is inserted into the inside of the guide plate, thereby fixing the sleeve on the slide. The sleeve remains fixed under the joint action of the edge plate and the positioning rod, which can reduce the force on the edge plate and increase the service life of the edge plate. At the same time, the positioning rod also fixes the slide, improves the position stability of the slide, and prevents the slide from being pushed by the compression spring and driving the sleeve to always squeeze the sealing plate, thereby increasing the service life of the sealing plate.

[0032] As another preferred embodiment, the control unit further includes:

[0033] A card plate for fixing the slide to the recorder body, the card plate being movably inserted into the interior of the slide;

[0034] a center plate provided on the sleeve and inserted into the interior of the sleeve; and

[0035] A wedge plate is provided on the center plate for pushing the clamping plate to move.

[0036] Specifically, a card slot corresponding to the card board is opened inside the recorder body. In the initial state, the card board is retracted inside the slide, and the card board is separated from the card slot.

[0037] When the pop-up plate extends outward to protect the recorder body, as shown in the figure, the slide moves to the left and extends, and the sleeve moves to the right and approaches the slide under the action of the tension spring. At this time, the wedge plate on the center plate pushes the card plate upward, so that the card plate is inserted into the card slot, thereby fixing the slide. In this way, after the recorder body falls to the ground, the elastic plate and the slide move back to the right due to the force of the ground. However, the slide will not move completely to the rightmost end, so that the elastic plate will not be completely retracted into the recorder body, so as to avoid the recorder body being easily damaged after the elastic plate is completely retracted, thereby improving the protection effect.

[0038] As a preferred embodiment, the transmission part includes:

[0039] A rack plate fixedly arranged on the sealing plate;

[0040] A gear assembly installed inside the recorder body, the pressure plate is driven by the rack plate through the gear assembly, and the pressure plate is provided with a tooth segment meshing with the gear assembly; and

[0041] A support spring is provided on the pressure plate, and the pressure plate is slidably mounted on the clamping member.

[0042] Specifically, the pressure plate is pushed by the support spring to maintain a stable relative position with the clamping member; when the clamping member is installed on the epaulette, the pressure plate presses against the epaulette;

[0043] One of the ways to support the spring is: Under normal circumstances, the recorder is light in weight and the pressure on the support spring is small, so the support spring is compressed and the pressure plate remains stable;

[0044] When an illegal person pulls the recorder body, excessive pressure is generated between the pressure plate and the epaulettes, causing the support spring to be squeezed and deformed, and the pressure plate moves relative to the clamping part, and drives the sealing plate to move through the gear assembly, opening the sealing plate and causing the elastic plate to pop outward;

[0045] By providing the gear assembly, according to the amplifying effect of the gear structure, even if the displacement amplitude of the pressure plate is small, the sealing plate can move a large distance, so that the elastic plate can be ejected smoothly.

[0046] As a preferred embodiment, the clamping member includes:

[0047] a fixed clamping plate provided on the recorder body, the pressure plate being movably mounted on the fixed clamping plate; and

[0048] The movable splint mounted on the fixed splint is rotatably mounted.

[0049] As another preferred embodiment, the mounting portion further comprises:

[0050] A mounting base fixedly provided on the recorder body, wherein the fixing clamp is installed in the mounting base;

[0051] A buckle provided on the mounting seat for clamping the movable splint inside the mounting seat; and

[0052] A button for ejecting the buckle is provided on the mounting seat.

[0053] Specifically, when wearing the recorder, the law enforcement officer passes the movable splint through the epaulette and fixes it on the mounting base, so that the clamping piece will not be easily separated from the epaulette; when removing the recorder, the law enforcement officer presses the button to pop out the buckle, and the movable splint can be smoothly removed from the epaulette, thereby removing the clamping piece from the epaulette;

[0054] Through this setting, when the recorder is worn, the clamping parts become a fixed structure that is stuck together, which not only improves the problem of the recorder falling off due to running during the law enforcement process; but also enables the epaulettes to contact the pressure plate more stably, and the pressure plate can perform pressure detection more smoothly.

[0055] As a preference, the sealing plates are connected as a whole via connecting rods.

[0056] Specifically, through this arrangement, after the pressure plate is subjected to pressure, it can drive all the sealing plates to open synchronously.

[0057] The beneficial effects of the present invention are:

[0058] The present invention provides a pop-up elastic plate in the recorder. When an illegal person pulls the recorder, the elastic plate pops outward, causing an impact on the illegal person's hand, causing pain and disturbance, causing him to let go, thereby playing a protective role. In addition, when the recorder falls, the elastic plate can play a buffering and protective role, having a dual protective effect, thereby improving the safety of the recorder.

[0059] The present invention provides a relatively movable sleeve on the slide. After the elastic plate is extended, the sleeve is separated from the curved section on the elastic plate, so that the curved section is opened. When the recorder falls to the ground, the contact area between the elastic plate and the ground can be increased, thereby better protecting the recorder.

[0060] The present invention provides a slidable slide and a clamping plate. After the slide drives the elastic plate to extend outward, the clamping plate clamps the slide to prevent the slide from falling out of the recorder. At the same time, it can prevent the elastic plate on the slide from being completely squeezed into the recorder after colliding with the ground. This improves the problem that the recorder is easily damaged after the elastic plate is fully retracted, thereby improving the protection effect.

[0061] The present invention provides a first layer of buffer protection by arranging an elastic plate with elasticity, a second layer of buffer protection by a tension spring on the sleeve, and a third layer of buffer protection by a compression spring on the slide seat. The three layers of protection are automatically triggered, and the protection effect is better.

[0062] The present invention detects the pressure state of the recorder by setting a pressure plate. When the recorder is pulled by an illegal person, the pressure on the pressure plate is too large, thereby opening the sealing plate and automatically releasing the elastic plate for protection. It is automatically triggered, has a simple structure, and is easy to use.

[0063] In summary, the present invention has the advantages of automatically triggering the elastic plate to pop out according to the stress condition of the recorder, being able to provide multi-layer protection, having a simple structure, and being easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0076] Example 1

[0077] like Figure 1-3 As shown, this embodiment provides a law enforcement recorder with a protective device, including a recorder body 7, and further comprising:

[0078] A retractable protection portion 1 is installed inside the recorder body 7, and the protection portion 1 includes an elastic plate 11 for buffering and protecting the recorder body 7;

[0079] A control unit 2 for controlling the extension and retraction state of the protection unit 1, wherein the control unit 2 includes a sealing plate 21 for blocking the protection unit 1;

[0080] A mounting portion 3 provided on the recorder body 7, wherein the mounting portion 3 includes a clamping member 31;

[0081] a detection portion 4 provided on the mounting portion 3 for detecting a stress state of the recorder main body 7 , the detection portion 4 comprising a pressure plate 41 mounted on the clamping member 31 ; and

[0082] The transmission unit 5 connects the detection unit 4 and the control unit 2.

[0083] Specifically, the elastic plate 11 is an elastic plastic plate or an elastic metal plate that can be bent, deformed and automatically reset; an open groove for placing the elastic plate 11 is opened on the recorder body 7; a lens assembly and a battery assembly are provided in the recorder body 7. Depending on the specific usage, the elastic plate 11 can be installed near the lens and battery to provide buffering protection for these key structures.

[0084] In the initial state, the protective plate is retracted inside the recorder body 7 to prevent the protective plate from being extended outward and easily obstructing the shooting of the lens or pressing against the body of the law enforcement officer to cause discomfort. The sealing plate 21 blocks the opening groove to play a sealing and protective role to prevent foreign matter from entering the recorder body 7.

[0085] Before enforcing the law, the staff clamps the clamp 31 on the epaulette to fix the recorder body 7 on the body of the law enforcement officer. The clamp 31 can also be adjusted according to the specific equipment worn by the law enforcement officer and installed on other devices. When someone tries to illegally pull off the recorder body 7, they will pull the recorder body 7 with force, causing the pressure plate 41 on the recorder body 7 to be subjected to excessive pressure. At this time, the control unit 2 is activated to open the sealing plate 21, so that the elastic plate 11 pops outward. The elastic plate 11 extending to the outside of the recorder body 7 can cause an impact on the hand of the illegal person, causing him to feel pain and disturbance, thereby loosening the recorder body 7. It can also provide buffer protection for the recorder body 7 when the recorder is pulled off by the illegal person and is still on the ground, so as to prevent key structures such as the lens and battery in the recorder body 7 from being damaged.

[0086] like Figure 2-5 As shown, further, the protection part 1 also includes:

[0087] A slide 12 slidably mounted inside the recorder body 7 , the elastic plate 11 being mounted on the slide 12 ; and

[0088] A sleeve 13 is slidably mounted on the slide seat 12 and is used to constrain the elastic plate 11 .

[0089] like Figure 4-5 As shown, further, the elastic plate 11 includes:

[0090] A straight edge segment 111 fixedly mounted on the slide 12; and

[0091] A curved section 112 is provided at the end of the straight section 111 and can extend outward, and the sleeve 13 is sleeved on the outside of the curved section 112 .

[0092] Specifically, the straight edge section 111 is fixedly mounted on the slide 12, a compression spring 121 is mounted on the slide 12, and a tension spring 132 is mounted on the sleeve 13. In the initial state, the slide 12 and the sleeve 13 are both retracted inside the recorder body 7, and the curved section 112 is compressed inside the sleeve 13. At this time, the compression spring 121 is in a compressed state, and the tension spring 132 is in a stretched state. When the elastic plate 11 extends to the outside of the recorder body 7, the curved section 112 extends from the sleeve 13 and expands outward.

[0093] In the initial state, the bent section 112 of the elastic plate 11 is straightened by the sleeve 13 so that the elastic plate 11 can be retracted into the interior of the recorder body 7 and the elastic plate 11 can be smoothly extended from the recorder body 7;

[0094] When the elastic plate 11 extends to the outside of the recorder body 7, the bent section 112 separates from the sleeve 13, and the bent section 112 begins to expand outward. In this way, when the recorder body 7 falls to the ground, the contact area between the elastic plate 11 and the ground can be increased, so that the elastic plate 11 can contact the ground more easily and better protect the recorder body 7.

[0095] like Figure 2-4 As shown, further, the control unit 2 also includes:

[0096] a guide plate 22 inserted into the sleeve 13, wherein the guide plate 22 is fixed on the slide 12; and

[0097] A positioning rod 23 is provided on the sealing plate 21 for fixing the sleeve 13 on the guide plate 22 .

[0098] Specifically, both the sleeve 13 and the positioning rod 23 are provided with positioning grooves corresponding to the positioning rod 23 ; the guide plate 22 can slide on the slide 12 through the positioning rod 23 .

[0099] like Figure 2-3 As shown, further, an edge plate 131 is provided on the outer side of the sleeve 13 , and a step for clamping the edge plate 131 is provided inside the recorder body 7 .

[0100] Specifically, when the protection part 1 is installed inside the recorder body 7, the slide 12 is moved in the negative direction along the Z axis to Figure 2 For example, this movement can be achieved by providing a pull rod extending to the outside of the recorder body 7 on the right side of the slide 12, or by using a thimble to push the slide 12 from left to right. After the slide 12 and the sleeve 13 move rightward together for a distance, the edge plate 131 on the sleeve 13 is blocked by the step. Therefore, the sleeve 13 cannot continue to move rightward while the slide 12 can continue to move rightward, thereby causing the sleeve 13 and the slide 12 to be relatively displaced. The sleeve 13 that moves leftward relative to the slide 12 can straighten the bent section 112 on the elastic plate 11. In this process, the tension spring 132 on the sleeve 13 is also stretched.

[0101] After the slide 12 moves to the rightmost end, the sealing plate 21 is started to move downward and block the opening groove. At this time, the positioning rod 23 on the sealing plate 21 is inserted into the guide plate 22, thereby fixing the sleeve 13 on the slide 12. The sleeve 13 remains fixed under the joint action of the edge plate 131 and the positioning rod 23, which can reduce the force on the edge plate 131 and improve the service life of the edge plate 131. At the same time, the positioning rod 23 also fixes the slide 12, improves the position stability of the slide 12, and prevents the slide 12 from being pushed by the compression spring 121, driving the sleeve 13 to always squeeze the sealing plate 21, thereby improving the service life of the sealing plate 21.

[0102] like Figure 2-3 As shown, further, the control unit 2 also includes:

[0103] A clamping plate 24 for fixing the slide 12 to the recorder body 7, the clamping plate 24 being movably inserted into the interior of the slide 12;

[0104] A center plate 25 provided on the sleeve 13 and inserted into the interior of the sleeve 13; and

[0105] A wedge plate 26 is provided on the center plate 25 for pushing the clamping plate 24 to move.

[0106] Specifically, a card slot 71 corresponding to the card plate 24 is formed inside the recorder body 7. The length of the card slot 71 is greater than the length of the card plate 24. In the initial state, the card plate 24 is retracted inside the slide 12, and the card plate 24 is separated from the card slot 71.

[0107] When the pop-up plate extends outward to protect the recorder body 7, Figure 3As shown, the slide 12 moves to the left and extends out, and the sleeve 13 moves to the right and approaches the slide 12 under the action of the tension spring 132. At this time, the wedge plate 26 on the center plate 25 pushes the card plate 24 upward, so that the card plate 24 is inserted into the card slot 71, thereby fixing the slide 12. In this way, after the recorder body 7 falls to the ground, the elastic plate 11 and the slide 12 are moved back to the right by the force of the ground. However, the slide 12 will not move completely to the rightmost end, so that the elastic plate 11 will not be completely retracted into the recorder body 7, so as to avoid the recorder body 7 being easily damaged after the elastic plate 11 is completely retracted, thereby improving the protection effect; in addition, the card plate 24 can also prevent the slide 12 from falling off from the recorder body 7 due to excessive outward extension.

[0108] like Figure 6-8 As shown, further, the transmission part 5 includes:

[0109] A rack plate 51 fixedly mounted on the sealing plate 21;

[0110] A gear assembly 52 installed inside the recorder body 7, the pressure plate 41 is driven by the rack plate 51 through the gear assembly 52, and the pressure plate 41 is provided with a tooth segment meshing with the gear assembly 52; and

[0111] A support spring 53 is provided on the pressure plate 41 , and the pressure plate 41 is slidably mounted on the clamping member 31 .

[0112] Specifically, the pressure plate 41 is pushed by the support spring 53 to maintain a stable relative position with respect to the clamping member 31; when the clamping member 31 is installed on the epaulette, the pressure plate 41 presses against the epaulette;

[0113] One way of supporting the spring 53 is as follows: Under normal circumstances, the recorder is light in weight and the pressure exerted on the supporting spring 53 is small, so the supporting spring 53 is compressed and the pressure plate 41 remains stable;

[0114] When an illegal person pulls the recorder body 7, excessive pressure is generated between the pressure plate 41 and the epaulettes, causing the support spring 53 to be squeezed and deformed, and the pressure plate 41 moves relative to the clamping member 31, and drives the sealing plate 21 to move through the gear assembly 52, opening the sealing plate 21 and causing the elastic plate 11 to pop outward;

[0115] By providing the gear assembly 52 , due to the amplification effect of the gear structure, even if the displacement amplitude of the pressure plate 41 is small, the sealing plate 21 can move a large distance, so that the elastic plate 11 can be ejected smoothly.

[0116] Example 2

[0117] like Figure 7-8As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0118] In this embodiment, further, the clamping member 31 includes:

[0119] A fixed clamping plate 311 provided on the recorder body 7, and the pressure plate 41 is movably mounted on the fixed clamping plate 311; and

[0120] The movable clamping plate 312 mounted on the fixed clamping plate 311 is rotated.

[0121] like Figure 2-8 As shown, further, the mounting portion 3 further includes:

[0122] A mounting base 32 is fixedly provided on the recorder body 7, and the fixing clamp 311 is installed in the mounting base 32;

[0123] A buckle 33 provided on the mounting seat 32 for clamping the movable splint 312 inside the mounting seat 32; and

[0124] A button 34 for ejecting the buckle 33 is provided on the mounting seat 32 .

[0125] Specifically, when the law enforcement officer wears the recorder, the movable splint 312 is passed through the epaulette and fixedly clamped on the mounting base 32, so that the clamping member 31 will not be easily separated from the epaulette; when removing the recorder, the button 34 is pressed to pop out the buckle 33, and the movable splint 312 can be smoothly removed from the epaulette, thereby removing the clamping member 31 from the epaulette;

[0126] Through this arrangement, when the recorder is worn, the clamping part 31 becomes a fixed structure that is stuck together, which not only improves the problem of the recorder falling off due to running during the law enforcement process; but also enables the epaulettes to contact the pressure plate 41 more stably, and the pressure plate 41 can perform pressure detection more smoothly.

[0127] Example 3

[0128] like Figure 9 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The differences between the third embodiment and the first embodiment are:

[0129] In this embodiment, further, the sealing plates 21 are connected as a whole via a connecting rod 6 .

[0130] Specifically, through this arrangement, after the pressure plate 41 is subjected to pressure, it can drive all the sealing plates 21 to open synchronously.

[0131] Working steps

[0132] Step 1: When wearing the recorder, the law enforcement officer installs the clamping member 31 into the mounting seat 32, then passes the movable splint 312 through the epaulette, and fixes the clamping member 31 to the mounting seat 32 through the buckle 33, and the pressure plate 41 is clamped above the epaulette;

[0133] Step 2: During the law enforcement recording process, if an illegal person forcibly pulls the recorder, the pressure between the pressure plate 41 and the epaulettes will be too large, causing the pressure plate 41 to move and open the sealing plate 21 through the transmission part 5;

[0134] Step 3: After the sealing plate 21 is opened, the positioning rod 23 separates from the guide plate 22, releasing the restraint on the slide 12. The slide 12 and the elastic plate 11 pop outward, causing an impact on the hands of the illegal person, causing pain and disturbance, causing the illegal person to let go.

[0135] Step 4: As the slide 12 moves outward, the sleeve 13 and the slide 12 are relatively displaced, so that the sleeve 13 and the curved section 112 on the elastic plate 11 are offset, and the curved section 112 expands outward to increase the contact area;

[0136] Step 5: When the sleeve 13 and the slide 12 are relatively displaced, the clamping plate 24 is pushed out by the center plate 25 and the wedge plate 26, and the clamping plate 24 is clamped in the clamping groove 71, thereby fixing the slide 12;

[0137] Step 6: When the recorder body 7 falls to the ground, the curved section 112 on the elastic plate 11 first contacts the ground. Since the curved section 112 is made of elastic material, the compressive deformation ability of the curved section 112 itself can provide the first layer of buffering protection for the recorder;

[0138] Step 7: The impact force of the ground on the elastic plate 11 is transmitted to the tension spring 132, and the tension spring 132 is squeezed and deformed, playing the role of a second layer of buffer protection;

[0139] Step 8. The impact force of the ground on the elastic plate 11 is simultaneously transmitted to the compression spring 121. By designing the slot 71, the length of the slot 71 is greater than the length of the card plate 24, and the card plate 24 can slide in the slot 71. Therefore, the compression spring 121 on the slide 12 is squeezed and deformed, playing the role of a third layer of buffer protection. In addition, the card plate 24 and the slot 71 can prevent the elastic plate 11 and the slide 12 from completely retracting into the recorder body 7, effectively protecting the recorder.

[0140] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
