Description

Technical Field

[0001] This utility model relates to the field of safety helmet testing technology, and more specifically to a safety helmet antistatic performance testing device. Background Technology

[0002] Currently, most existing safety helmet antistatic performance testing instruments are of the carrying case type, consisting of the testing instrument and the case lid. When not in use, the lid can be closed to protect the internal structure. The lid needs to be locked when closed. Most existing safety helmet antistatic performance testing instruments use a flat-mouth latch to lock the lid, which mainly consists of a hook, a flat-mouth lever, and a hanging rod. The hook is located on the lid, the flat-mouth lever is located on the testing instrument, and the hanging rod is located inside the flat-mouth lever. To unlock, the flat-mouth lever must first be pushed upward to disengage the hanging rod from the hook, and then the flat-mouth lever must be pushed downward to move the hanging rod away from the hook. To lock, the hanging rod must first be pressed into the hook, and then the flat-mouth lever must be pushed downward to lock the hanging rod and the hook together. The operation is quite inconvenient. Therefore, there is an urgent need to design a safety helmet antistatic performance testing device to solve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety helmet antistatic performance testing device to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a safety helmet antistatic performance testing device, comprising a testing instrument body and a cover rotatably mounted on the testing instrument body, and further comprising...

[0005] Two hooks are symmetrically fixed on one side of the box lid;

[0006] Two mounting components, including mounting rods, are symmetrically and laterally slidably mounted on one side of the detector body, and hooks can be attached to the bottom of the mounting rods;

[0007] The unlocking component is rotatably mounted on one side of the detector body and is located between two hook rods. Both hook rods are slidably connected to the unlocking component. The unlocking component can drive the two hook rods to slide closer to each other, thereby disengaging from the two hooks.

[0008] Two elastic components are symmetrically fixedly installed on one side of the detector body, and the hanging rod is slidably installed on the elastic components. The elastic components push the hanging rod to contact the hook.

[0009] Two ejector components are symmetrically and vertically elastically slidably installed inside the detector body, which can lift the box cover when the hook component is detached from the hook.

[0010] Furthermore, the hook is L-shaped with a semi-circular bottom, and the ends of the two hook rods that are far apart from each other are fan-shaped.

[0011] Furthermore, the elastic component includes a fixing block, which is fixedly installed on one side of the detector body. A strip-shaped hole is provided on the hanging rod, and the hanging rod is slidably installed on the fixing block through the strip-shaped hole.

[0012] Furthermore, the elastic component also includes two first springs, one end of each of the two first springs is fixedly installed on one end of the fixing block, and the other end of each of the two first springs is fixedly installed on the inner wall of one end of the strip hole.

[0013] Furthermore, the unlocking component includes a rotating rod and a rotating plate. The rotating rod is rotatably mounted on one side of the detector body, and the rotating rod is fixedly mounted on the rotating rod. Two arc-shaped grooves are equidistantly formed on the circumference of the rotating plate.

[0014] Furthermore, the mounting assembly also includes a fixing rod with a slot on it. The fixing rod is fixedly installed in the slot and slidably installed in the arc-shaped groove.

[0015] Furthermore, the ejection assembly includes an ejection rod and a second spring. Two vertical slots are symmetrically opened on the top of the detector body. The ejection rod is slidably installed in the vertical slots. A circular slot is opened at the bottom of the ejection rod. The second spring is fixedly installed between the inner wall of the top of the circular slot and the inner wall of the bottom of the vertical slot.

[0016] Furthermore, it also includes two contact plates, which are symmetrically fixed inside the cover.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This utility model, through the setting of hooks, hooking components, unlocking components, elastic components, and ejection components, allows the detector body to be used only by rotating the rotating rod and rotating plate counterclockwise when needed. This causes the two fixed rods to slide along the two arc-shaped grooves, bringing them closer together. This, in turn, causes the two hooking rods to slide closer together, disengaging them from the two hooks and unlocking the lid. At this time, the two second springs are released and push the two ejection rods upward, thereby pushing the two contact plates and the lid upward a certain distance, making it easy to open the lid.

[0019] After use, simply rotate the lid downwards to slide the two hooks downwards. As the two hooks slide downwards, they will press against the ends of the two connecting rods that are far apart, causing the two connecting rods to slide closer together and compress the four first springs respectively. When the lid rotates to fit against the detector body, the bottoms of the two hooks will also slide to disengage from the ends of the two connecting rods. At this time, the four first springs will be released and push the two connecting rods away from each other. The connecting rods will then slide into the L-shaped bend of the hooks, thus limiting the hooks and locking the two hooks and the lid. Attached Figure Description

[0026] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 4 The present invention will be further described below.

[0027] The safety helmet antistatic performance testing device includes a testing instrument body 1 and a cover 2 rotatably mounted on the testing instrument body 1, and also includes...

[0028] Two hooks 3 are symmetrically fixedly installed on one side of the box cover 2;

[0029] Two hanging components 4, including hanging rods 401, are symmetrically and laterally slidably installed on one side of the detector body 1, and hooks 3 can be hung below the hanging rods 401.

[0030] Unlocking component 5 is rotatably installed on one side of the detector body 1 and is located between two hook rods 401. Both hook rods 401 are slidably connected to unlocking component 5. Unlocking component 5 can drive the two hook rods 401 to slide closer to each other and thus disengage from the two hooks 3.

[0031] Two elastic components 6 are symmetrically fixedly installed on one side of the detector body 1. The hanging rod 401 is slidably installed on the elastic components 6. The elastic components 6 push the hanging rod 401 to contact the hook 3.

[0032] Two ejector components 8 are symmetrically and vertically elastically slidably installed inside the detector body 1, which can lift the box cover 2 when the hook component 4 is disengaged from the hook 3.

[0033] In this embodiment, when the lid 2 is locked, the two elastic components 6 push the two hook components 4 to contact the two hooks 3, thereby locking the two hooks 3 and the lid 2. When the detector body 1 needs to be used, rotating the unlocking component 5 can drive the two hook components 4 to slide closer to each other, thereby disengaging the two hook components 4 from the two hooks 3, thus unlocking the lid 2. At this time, the two ejecting components 8 will pop out, thereby lifting the lid 2 a certain distance.

[0034] Specifically, hook 3 is L-shaped with a semi-circular bottom, and the ends of the two hook rods 401 that are far apart from each other are fan-shaped.

[0035] In this embodiment, when the lid 2 is locked, the two hook rods 401 are respectively located at the L-shaped bends of the two hooks 3, which can block the hooks 3. When the lid 2 is closed, the bottom of the semi-circular hook 3 can smoothly press one end of the fan-shaped hook rod 401.

[0036] Specifically, the elastic component 6 includes a fixing block 601 and two first springs 602. The fixing block 601 is fixedly installed on one side of the detector body 1. The hanging rod 401 has a strip hole 404. The hanging rod 401 is slidably installed on the fixing block 601 through the strip hole 404. One end of each of the two first springs 602 is fixedly installed on one end of the fixing block 601, and the other end of each of the two first springs 602 is fixedly installed on the inner wall of one end of the strip hole 404.

[0037] In this embodiment, when the lid 2 is locked, the first spring 602 is released, and the four first springs 602 respectively cause the two hook rods 401 to be at the L-shaped bends of the two hooks 3.

[0038] Specifically, the unlocking component 5 includes a rotating rod 501 and a rotating plate 502. The rotating rod 501 is rotatably mounted on one side of the detector body 1. The rotating rod 501 is fixedly mounted on the rotating rod 501. Two arc-shaped grooves 503 are equidistantly opened on the circumference of the rotating plate 502. The hanging component 4 also includes a fixing rod 403. The hanging rod 401 has a hollow groove 402. The fixing rod 403 is fixedly installed in the hollow groove 402 and slidably installed in the arc-shaped groove 503.

[0039] In this embodiment, when the detector body 1 is needed, rotating the rotating rod 501 counterclockwise causes the rotating plate 502 to rotate counterclockwise. When the rotating plate 502 rotates counterclockwise, it causes the two fixed rods 403 to slide along the two arc-shaped grooves 503 respectively, which allows the two fixed rods 403 to slide closer to each other. The sliding of the two fixed rods 403 can cause the two hook rods 401 to slide closer to each other. The sliding of the two hook rods 401 will disengage from the two hooks 3 and compress the four first springs 602 respectively, thereby unlocking the two hooks 3 and unlocking the box cover 2.

[0040] Specifically, the ejector assembly 8 includes an ejector rod 801 and a second spring 803. The top of the detector body 1 has two vertical grooves 7 symmetrically opened. The ejector rod 801 is slidably installed in the vertical grooves 7. The bottom of the ejector rod 801 has a circular groove 802. The second spring 803 is fixedly installed between the top inner wall of the circular groove 802 and the bottom inner wall of the vertical groove 7. It also includes two contact plates 9, which are symmetrically fixedly installed in the box cover 2.

[0041] In this embodiment, when the lid 2 is locked, the contact plate 9 is in contact with the top of the ejector rod 801, and the second spring 803 is in a compressed state. After the lid 2 is unlocked, the two second springs 803 will release and push the two ejector rods 801 to slide upward. The ejector rods 801 sliding upward will push the two contact plates 9, thereby lifting the lid 2.

[0042] Working principle: When the detector body 1 needs to be used, rotate the rotating rod 501 counterclockwise, which will drive the rotating plate 502 to rotate counterclockwise. When the rotating plate 502 rotates counterclockwise, it will drive the two fixed rods 403 to slide along the two arc grooves 503 respectively, so that the two fixed rods 403 can slide closer to each other. The two fixed rods 403 sliding closer to each other will drive the two hook rods 401 to slide closer to each other. The two hook rods 401 sliding closer to each other will disengage from the two hooks 3 and compress the four first springs 602 respectively, thereby unlocking the two hooks 3 and unlocking the box cover 2. At this time, the two second springs 803 will be released and push the two push rods 801 to slide upward. The push rods 801 will push the contact plate 9 to lift the box cover 2 a distance, making it convenient for the user to open the box cover 2. At this time, the rotating rod 501 can be released, and the four first springs 602 will be released and push the two hook rods 401 to reset respectively.

[0043] After use, the lid 2 can be rotated downwards. During the rotation, the lid 2 will cause the two hooks 3 to slide downwards. When the bottom of the two hooks 3 slides downwards, it will press the ends of the two hook rods 401 that are far apart from each other, causing the two hook rods 401 to slide closer to each other and compress the four first springs 602 respectively. When the lid 2 rotates to fit against the detector body 1, the bottom of the two hooks 3 will also slide to disengage from the ends of the two hook rods 401. At this time, the four first springs 602 will be released and push the two hook rods 401 to slide away from each other. At this time, the hook rods 401 will slide into the L-shaped bend of the hook 3 to limit the hook 3, thereby locking the two hooks 3 and the lid 2. During the downward rotation, the lid 2 will also cause the two contact plates 9 to press down the two push rods 801, causing the two push rods 801 to retract into the vertical groove 7 and compress the two second springs 803.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
