Description

Technical Field

[0001] The utility model relates to the technical field of laser methane detectors, and particularly relates to a handheld laser methane detector. Background Art

[0002] With the advancement of laser methane detection technology, the detection speed, accuracy, and convenience of natural gas leakage have been improved, and it has been widely promoted and applied. For handheld or portable laser methane detectors, they generally include a housing, and a laser sighting module, a circuit module, a display module, a power module, etc. assembled in the housing. The laser sighting module generally includes a sighting scope, a laser emission and reception channel, and a laser body part, and this module is generally installed at the front end of the housing;

[0003] As shown in the reference case "A Handheld Laser Methane Detector" with the publication number "CN218036383U", when the control switch is turned on, the controller is controlled to start the searchlight and the servo motor to work. The controller is connected to each device. After the device detects, the detection data is transmitted to above the display screen through the controller, making the device easy to carry and improving the detection quality of the device. The air enters the detection chamber through the baffle, and the quality of methane in the air is detected through gas flow, further improving the detection effect of the device and the practicality of the device;

[0004] When the existing handheld laser methane detector is carried and moved, the laser detection end of the detector is usually directly connected to the outside. If the detector is bumped during the movement, it is easy to directly damage the laser detection end, resulting in economic losses.

[0005] Therefore, a handheld laser methane detector is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a handheld laser methane detector to solve the above problems, improving the problem that when the existing handheld laser methane detector is carried and moved, the laser detection end of the detector is usually directly connected to the outside. If the detector is bumped during the movement, it is easy to directly damage the laser detection end, resulting in economic losses.

[0007] The utility model realizes the above object through the following technical solutions. A handheld laser methane detector includes: a laser methane detector, a handle fixedly installed on one side of the laser methane detector, a light-shielding cover fixedly installed on one side of the laser methane detector, and a protection and positioning mechanism. The protection and positioning mechanism for protecting the laser methane detector during carrying and moving is arranged on one side of the light-shielding cover. Among them, the protection and positioning mechanism includes a protection plate rotatably installed on one side of the light-shielding cover. A protection component is arranged on one side of the protection plate, and a positioning component is arranged on the other side of the protection plate. When it is necessary to carry and move the laser methane detector, the protection component can be used to quickly shield and protect its laser detection end, so that the laser detection end of the laser methane detector is effectively protected during carrying and moving, avoiding damage caused by external impacts or other physical factors. The positioning component ensures that the protection plate can be stably maintained at the required position during movement or use, preventing displacement due to vibration or misoperation.

[0008] Preferably, the protection component includes a rubber plate fixedly installed on one side of the protection plate. The rubber plate is triangular in shape, and the volume of the rubber plate is smaller than that of the light-shielding cover. When protection is required, the protection plate can be rotated to drive the rubber plate into the interior of the light-shielding cover and be clamped with the inner wall of the light-shielding cover, thereby completing the shielding and protection of the laser detection end of the laser methane detector and preventing external objects from directly hitting the laser detection end during transportation or carrying.

[0009] Preferably, the protection component further includes a pressing frame slidably installed inside the light-shielding cover. The pressing frame is located on one side of the rubber plate. A plurality of support rods are fixedly installed on one side of the pressing frame. One ends of the plurality of support rods are all slidably connected to the laser methane detector. A spring is sleeved on the outer side of the support rod. The two ends of the spring are respectively fixedly connected to the pressing frame and the laser methane detector. When an external impact occurs, the rubber plate can absorb the impact. When the rubber plate enters the interior of the light-shielding cover, one side of the rubber plate abuts against the pressing frame, and the support rods push the pressing frame to slide inside the light-shielding cover. The spring provides the necessary resilience to ensure that the pressing frame can maintain a relatively static state without external impact, and when suffering from an external impact, the spring can absorb part of the impact force and at the same time push the pressing frame against the rubber plate, thereby forming a strong protection barrier.

[0010] Preferably, the interior of the rubber plate is a hollow structure, and a plurality of buffer plates are fixedly installed inside the rubber plate. The plurality of buffer plates are evenly distributed. When the rubber plate is in use, it can cooperate with the internal cavity and the plurality of buffer plates. When an external impact occurs, the impact force can be dispersed to different areas, thereby reducing the pressure on a single point and improving the overall protection efficiency.

[0011] Preferably, the positioning component includes a fixed block fixedly installed on one side of the protective plate. The fixed block is triangular in shape, and a card slot is formed on one side of the fixed block. When the protective plate is opened, one side of the fixed block contacts one side of the light-shielding cover to support the protective plate and prevent the protective plate from rotating excessively.

[0012] Preferably, a clamping block is fixedly installed on one side of the light-shielding cover. The shape of the clamping block is adapted to the card slot. When the fixed block contacts one side of the light-shielding cover, the card slot and the clamping block can be clamped with each other, so as to realize the stable positioning of the protective plate and prevent the protective plate from shaking during the use of the laser methane detector, which affects the use.

[0013] Preferably, a plurality of pressing blocks are fixedly installed on one side of the rubber plate, and a plurality of friction grooves are formed on the surfaces of the plurality of pressing blocks. When the rubber plate enters the inside of the light-shielding cover, the plurality of pressing blocks can be squeezed to press against the inner wall of the light-shielding cover, providing additional friction force, so as to ensure that the rubber plate is stably fixed inside the light-shielding cover and prevent it from sliding or falling off due to vibration or movement. The friction grooves on the pressing blocks can increase the friction of the contact surface, and even in the case of intense movement or impact, the rubber plate can be prevented from falling off the inner wall of the light-shielding cover.

[0014] The beneficial effects of the present utility model are:

[0015] 1. When it is necessary to carry and move the laser methane detector, the protection component can be used to quickly shield and protect the laser detection end of the detector. When the laser detection end of the laser methane detector is carried and moved, it can be effectively protected to avoid damage caused by external impact or other physical factors. The positioning component ensures that the protective plate can be stably maintained at the required position during movement or use, preventing displacement due to vibration or misoperation;

[0016] 2. When the fixed block contacts one side of the light-shielding cover, the card slot and the clamping block can be clamped with each other, so as to realize the stable positioning of the protective plate and prevent the protective plate from shaking during the use of the laser methane detector. When the rubber plate enters the inside of the light-shielding cover, the plurality of pressing blocks can be squeezed to press against the inner wall of the light-shielding cover, providing additional friction force, so as to ensure that the rubber plate is stably fixed inside the light-shielding cover and prevent it from sliding or falling off due to vibration or movement.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1 - 5 shown, a handheld laser methane detector includes: a laser methane detector 1, a grip 11 fixedly installed on one side of the laser methane detector 1, a light-shielding cover 2 fixedly installed on one side of the laser methane detector 1, and a protection and positioning mechanism 3 for protecting and positioning when the laser methane detector 1 is carried and moved is arranged on one side of the light-shielding cover 2. Among them, the protection and positioning mechanism 3 includes a protection plate 31 rotatably installed on one side of the light-shielding cover 2, a protection component 32 is arranged on one side of the protection plate 31, and a positioning component 33 is arranged on the other side of the protection plate 31. When it is necessary to carry and move the laser methane detector 1, the protection component 32 can be used to quickly block and protect its laser detection end, so that the laser detection end of the laser methane detector 1 is effectively protected during carrying and moving, and damage caused by external impact or other physical factors is avoided. The positioning component 33 ensures that the protection plate 31 can be stably maintained in the required position during movement or use, preventing displacement due to vibration or misoperation.

[0025] As Figure 2 and Figure 3As shown, the protection component 32 includes a rubber plate 321 fixedly installed on one side of the protection plate 31. The rubber plate 321 is triangular in shape, and the volume of the rubber plate 321 is smaller than that of the light-shielding cover 2. When protection is needed, the protection plate 31 can be rotated to drive the rubber plate 321 into the interior of the light-shielding cover 2 and be clamped against the inner wall of the light-shielding cover 2, thus completing the shielding protection of the laser detection end of the laser methane detector 1, avoiding direct impact of external objects on the laser detection end during transportation or carrying. The protection component 32 also includes a pressing frame 323 slidably installed inside the light-shielding cover 2. The pressing frame 323 is located on one side of the rubber plate 321. A plurality of support rods 324 are fixedly installed on one side of the pressing frame 323. One ends of the plurality of support rods 324 are all slidably connected to the laser methane detector 1. A spring 325 is sleeved outside the support rod 324. Two ends of the spring 325 are respectively fixedly connected to the pressing frame 323 and the laser methane detector 1. When an external impact occurs, the rubber plate 321 can absorb the impact. And when the rubber plate 321 enters the interior of the light-shielding cover 2, one side thereof abuts against the pressing frame 323, and the support rod 324 pushes the pressing frame 323 to slide inside the light-shielding cover 2, while the spring 325 provides the necessary resilience to ensure that the pressing frame 323 can maintain a relatively static state without external impact. And when suffering from an external impact, the spring 325 can absorb part of the impact force and at the same time push the pressing frame 323 to closely adhere to the rubber plate 321, thus forming a strong protection barrier. The interior of the rubber plate 321 is a hollow structure, and a plurality of buffer plates 322 are fixedly installed inside the rubber plate 321. The plurality of buffer plates 322 are evenly distributed. When the rubber plate 321 is in use, it can cooperate with the internal cavity and the plurality of buffer plates 322. When an external impact occurs, the impact force can be dispersed to different areas, thereby reducing the pressure on a single point and improving the overall protection efficiency.

[0026] As Figure 2 , Figure 4 and Figure 5As shown in the figure, the positioning component 33 includes a fixed block 331 fixedly installed on one side of the protection plate 31. The fixed block 331 is triangular in shape. A clamping groove 332 is formed on one side of the fixed block 331. When the protection plate 31 is opened, one side of the fixed block 331 contacts one side of the light-shielding cover 2 to support the protection plate 31 and prevent the protection plate 31 from rotating excessively. A clamping block 333 is fixedly installed on one side of the light-shielding cover 2. The shape of the clamping block 333 is adapted to that of the clamping groove 332. When the fixed block 331 contacts one side of the light-shielding cover 2, the clamping groove 332 and the clamping block 333 can be clamped with each other, so as to realize the stable positioning of the protection plate 31 and prevent the protection plate 31 from shaking during the use of the laser methane detector 1 and affecting the use. A plurality of pressing blocks 334 are fixedly installed on one side of the rubber plate 321. A plurality of friction grooves 335 are formed on the surfaces of the plurality of pressing blocks 334. When the rubber plate 321 enters the interior of the light-shielding cover 2, the plurality of pressing blocks 334 can be squeezed to press against the inner wall of the light-shielding cover 2, providing additional friction force, so as to ensure that the rubber plate 321 is stably fixed inside the light-shielding cover 2 and prevent it from sliding or falling off due to vibration or movement. The friction grooves 335 on the pressing blocks 334 can increase the friction of the contact surface, and even in the case of intense movement or impact, the rubber plate 321 can be prevented from falling off the inner wall of the light-shielding cover 2.

[0027] When the utility model is in use, when protection is needed, the protection plate 31 can be rotated to drive the rubber plate 321 into the interior of the light-shielding cover 2 and be clamped with the inner wall of the light-shielding cover 2, so as to complete the shielding protection of the laser detection end of the laser methane detector 1, avoiding direct impact of external objects on the laser detection end during transportation or carrying. When an external impact occurs, the rubber plate 321 can absorb the impact. When the rubber plate 321 enters the interior of the light-shielding cover 2, one side thereof abuts against the abutting frame 323, and the support rod 324 pushes the abutting frame 323 to slide inside the light-shielding cover 2, while the spring 325 provides the necessary resilience to ensure that the abutting frame 323 can maintain a relatively static state without external impact. When suffering from an external impact, the spring 325 can absorb part of the impact force and at the same time push the abutting frame 323 against the rubber plate 321, thereby forming a solid protection barrier. When the rubber plate 321 is in use, it can cooperate with a plurality of buffer plates 322 through the internal cavity, and can disperse the impact force to different areas when an external impact occurs, thereby reducing the pressure on a single point and improving the overall protection effect. When the fixed block 331 contacts one side of the light-shielding cover 2, the card slot 332 and the card block 333 can be engaged with each other to realize the stable positioning of the protection plate 31 and prevent the protection plate 31 from shaking when the laser methane detector 1 is in use. When the rubber plate 321 enters the interior of the light-shielding cover 2, it can squeeze a plurality of abutting blocks 334 to abut against the inner wall of the light-shielding cover 2, providing additional friction force, so as to ensure the stable fixation of the rubber plate 321 inside the light-shielding cover 2 and prevent it from sliding or falling off due to vibration or movement. The friction grooves 335 on the abutting blocks 334 can increase the friction of the contact surface, and even in the case of intense movement or impact, the rubber plate 321 can be prevented from falling off the inner wall of the light-shielding cover 2.

The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
