Description

Technical Field

[0001] This invention relates to the field of measuring equipment technology, and specifically to an automatic calibration device for a handheld laser rangefinder. Background Technology

[0002] A handheld laser rangefinder is an instrument that uses a laser to accurately measure the distance to a target. A thin laser beam is used, and a photoelectric element receives the laser beam reflected from the target. A timer measures the time from the emission of the laser beam to its reception, thereby calculating the distance from the observer to the target.

[0003] Existing handheld laser rangefinders are small in size, making heat dissipation difficult after prolonged use. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic calibration device for a handheld laser rangefinder, which solves the related problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides a handheld laser rangefinder automatic calibration device, including a housing assembly and a rangefinder body. The housing assembly is mainly composed of two half-shells joined together. The end of each half-shell is a connecting section, and a fixing ring is installed on the connecting section to fix the two half-shells. Each half-shell has a flat surface with a snap-fit ​​opening. Two symmetrical tube openings are provided on each half-shell. The rangefinder body has a columnar structure, and the end of the rangefinder body is located within the connecting section. The gap between the end of the rangefinder body and the connecting section is sealed by a sealing ring. The body has a protruding structure that mates with the bayonet. A channel is formed between the rangefinder body and the inner wall of the semi-shell. The channel is connected to two ports. A motor is installed in another connecting section of the semi-shell. A propulsion blade is installed on the output end of the motor. The propulsion blade is located in the channel. The heat generated inside the laser component during operation is not easy to dissipate. The propulsion blade is driven by the motor to rotate, so that the propulsion blade pushes the air in the channel formed between the rangefinder body and the inner wall of the semi-shell to one side, and it is discharged through one port and then enters through the other port. The air flowing through the channel completes the heat dissipation.

[0006] Furthermore, the connecting sections at both ends of the first half-shell form a narrowing structure. The connecting sections are provided with external threads, and the fixing rings are provided with internal threads that mesh with the external threads of the connecting sections. The two half-shells are fixedly installed by the fixing rings installed on the outside of the connecting sections. The narrowing structure of the connecting sections at both ends of the first half-shell facilitates increasing the volume of the channel formed between the rangefinder body and the inner wall of the first half-shell, thereby improving the heat exchange effect.

[0007] Furthermore, the bottom of the propulsion blade is a disc, on which several blades are arranged in a ring. The surrounding blades are fitted onto the end of the rangefinder body, which facilitates the flow of air from one end of the rangefinder body to the other, thereby improving the heat dissipation effect.

[0008] Furthermore, it also includes a heat dissipation channel, which is mainly composed of two half-shells joined together. Two pipe openings are symmetrically provided on the half-shells, and the pipe openings are connected to the pipe openings through a connecting pipe.

[0009] Furthermore, end caps are fitted onto the ports formed by the two semi-shells, and tubular components are installed inside the semi-shells. The ports of the tubular components are connected to the end caps, and a channel is formed between the tubular components and the semi-shells. The channel is connected to the channel through a connecting pipe. A propulsion blade is installed on the output end of the motor to push the air inside the channel into the channel, thereby realizing the air circulation between the channel and the channel and preventing external air from entering the interior of the channel. This effectively solves the problem of dust accumulation inside the equipment after long-term heat dissipation.

[0010] The main body of the tubular component is a tube, and the outer side of the tube is provided with an external spiral blade. The tube is connected to the outside through the port of the end cap.

[0011] Furthermore, the inner side of the tube body is provided with internal threads. The tube body is connected to the coolant pipe through the port of the end cap. Under the condition of high external ambient temperature, the heat exchange effect between the flowing air and the surrounding air is poor. The tube body is connected to the cooling water pipe through the port of the end cap. Since the inner side of the tube body is provided with internal threads, the passing cooling water drives the tube body to rotate. The outer spiral blades provided on the outside of the tube body push the air flow inside the second channel, thereby promoting the air flow inside the second channel and the first channel. Heat exchange is carried out through the tube body, improving the heat exchange effect and improving the heat dissipation effect on the rangefinder body.

[0012] Furthermore, a sealing strip can be installed at the joint of the semi-shell to improve the sealing effect.

[0013] Furthermore, several heat dissipation fins are provided on the outer surface of the rangefinder body to improve the heat exchange effect.

[0014] The present invention has the following beneficial effects:

[0015] 1. During the operation of the laser component of the present invention, the internal temperature generated is not easy to dissipate. The propulsion blade is driven by a motor to rotate, so that the propulsion blade pushes the air in the channel formed between the rangefinder body and the inner wall of the semi-shell to one side, and the air is discharged through one pipe and then enters through another pipe. The air flowing through the channel completes the heat dissipation.

[0016] 2. The present invention uses a propulsion blade installed on the output end of the motor to push the air inside the first channel into the second channel, thereby realizing the air circulation between the second channel and the first channel. This prevents external air from entering the first channel and effectively solves the problem of dust accumulation inside the equipment after long-term heat dissipation.

[0017] 3. Under conditions of high external ambient temperature, the heat exchange effect between the flowing air and the surrounding air is poor. The end cap is connected to the cooling water pipe. Since the inner side of the pipe is provided with internal threads, the passing cooling water drives the pipe to rotate. The outer side of the pipe is provided with external spiral blades to push the air inside the second channel, thereby promoting the air flow inside the second channel and the first channel. Heat exchange is carried out through the pipe, improving the heat exchange effect and improving the heat dissipation effect on the rangefinder body.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Example

[0027] Please see Figures 1-2 As shown, this invention is an automatic calibration device for a handheld laser rangefinder, comprising a housing assembly and a rangefinder body 4. The housing assembly is mainly composed of two half-shells 1 joined together. The ends of the half-shells 1 are connecting sections 102, on which fixing rings 2 are installed to fix the two half-shells 1. The half-shells 1 have a plane 101 with a bayonet 104. Two symmetrical tube openings 103 are provided on the half-shells 1. The rangefinder body 4 has a columnar structure. The end of the rangefinder body 4 is located in a connecting section 102. At the same time, the gap formed between the end of the rangefinder body 4 and the connecting section 102 is sealed by a sealing ring 3. The rangefinder body 4 is provided with a protruding structure 401 that cooperates with the bayonet 104. A channel is formed between the rangefinder body 4 and the inner wall of the half-shell 1. The channel is connected to two pipe openings 103. A motor 10 is installed in another connecting section 102 of the half-shell 1. A propulsion blade 8 is installed on the output end of the motor 10. The propulsion blade 8 is located in the channel.

[0028] During operation, the heat generated inside the laser component is difficult to dissipate. The motor 10 drives the propulsion blade 8 to rotate, which in turn pushes the air in the channel formed between the rangefinder body 4 and the inner wall of the semi-shell 1 to one side. The air is discharged through one port 103 and then enters through the other port 103. The air flowing through the channel is used to dissipate heat. Example

[0029] Please see Figures 1-3As shown, this invention is an automatic calibration device for a handheld laser rangefinder, comprising a housing assembly and a rangefinder body 4. The housing assembly is mainly composed of two half-shells 1 joined together. The ends of the half-shells 1 are connecting sections 102, on which fixing rings 2 are installed to fix the two half-shells 1. The half-shells 1 have a plane 101 with a bayonet 104. Two symmetrical tube openings 103 are provided on the half-shells 1. The rangefinder body 4 has a columnar structure. The end of the rangefinder body 4 is located in a connecting section 102. At the same time, the gap formed between the end of the rangefinder body 4 and the connecting section 102 is sealed by a sealing ring 3. The rangefinder body 4 is provided with a protruding structure 401 that cooperates with the bayonet 104. A channel is formed between the rangefinder body 4 and the inner wall of the half-shell 1. The channel is connected to two pipe openings 103. A motor 10 is installed in another connecting section 102 of the half-shell 1. A propulsion blade 8 is installed on the output end of the motor 10. The propulsion blade 8 is located in the channel.

[0030] During operation, the heat generated inside the laser component is difficult to dissipate. The motor 10 drives the propulsion blade 8 to rotate, which in turn pushes the air in the channel formed between the rangefinder body 4 and the inner wall of the semi-shell 1 to one side. The air is discharged through one port 103 and then enters through the other port 103. The air flowing through the channel is used to dissipate heat.

[0031] The connecting sections 102 at both ends of the half-shell 1 form a narrowing structure. The connecting sections 102 are provided with external threads, and the fixing ring 2 is provided with internal threads that mesh with the external threads of the connecting sections 102. The two half-shells 1 are fixedly installed by the fixing ring 2 installed on the outside of the connecting sections 102. The connecting sections 102 at both ends of the half-shell 1 form a narrowing structure, which makes it easier to increase the volume of the channel formed between the rangefinder body 4 and the inner wall of the half-shell 1, thereby improving the heat exchange effect.

[0032] The bottom of the propulsion blade 8 is a disc, on which several blades are arranged in a ring. The surrounding blades are fitted onto the end of the rangefinder body 4, which facilitates the flow of air from one end of the rangefinder body 4 to the other, thereby improving the heat dissipation effect.

[0033] It also includes a heat dissipation channel, which is mainly composed of two half-shells 26 spliced ​​together. Two pipe ports 2601 are symmetrically provided on the half-shells 26, and the pipe ports 2601 and the pipe port 103 are connected by a connecting pipe 5.

[0034] An end cap 7 is fitted onto the port formed by the two half-shells 2 6. A tubular component 9 is installed inside the half-shell 2 6. The port of the tubular component 9 is connected to the end cap 7. A channel 2 is formed between the tubular component 9 and the half-shell 2 6. The channel 2 is connected to the channel 1 by a connecting pipe 5.

[0035] The motor 10 has a propulsion blade 8 installed on its output end, which pushes the air inside the first channel into the second channel, realizing the air circulation between the second channel and the first channel. This prevents external air from entering the first channel and effectively solves the problem of dust accumulation inside the equipment after long-term heat dissipation. Example

[0036] Please see Figures 1-4 As shown, the main body of the tubular component 9 is a tube body 901, and an outer spiral blade 902 is provided on the outside of the tube body 901. The tube body 901 is connected to the outside through the port of the end cap 7.

[0037] The inner side of the tube body 901 is provided with internal threads, and the tube body 901 is connected to the coolant pipeline through the port of the end cap 7.

[0038] Under conditions of high external ambient temperature, the heat exchange effect between the flowing air and the surrounding air is poor. The end cap 7 is connected to the cooling water pipe. Since the inner side of the pipe body 901 is provided with internal threads, the passing cooling water drives the pipe body 901 to rotate. The outer spiral blades 902 provided on the outer side of the pipe body 901 push the air flow inside the second channel, thereby promoting the air flow inside the second channel and the first channel. Heat exchange is carried out through the pipe body 901, improving the heat exchange effect and improving the heat dissipation effect on the rangefinder body 4.

[0039] A sealing strip can be installed at the joint of the semi-shell 1 to improve the sealing effect.

[0040] Several heat dissipation fins are provided on the outer surface of the rangefinder body 4 to improve the heat exchange effect.

[0041] Working principle:

[0042] During operation, the rangefinder body 4 is calibrated and positioned by the auxiliary lines generated by the laser component. The heat generated inside the laser component during operation is not easy to dissipate. The motor 10 drives the propulsion blade 8 to rotate, so that the propulsion blade 8 pushes the air in the channel 1 formed between the rangefinder body 4 and the inner wall of the half shell 1 to one side, and discharges through one pipe port 103, and then enters through the other pipe port 103. The air is cooled by the air flowing through the channel 1.

[0043] The motor 10 has a propulsion blade 8 installed on its output end, which pushes the air inside the first channel into the second channel, realizing the air circulation between the second channel and the first channel. This prevents external air from entering the first channel and effectively solves the problem of dust accumulation inside the equipment after long-term heat dissipation.

[0044] Under conditions of high external ambient temperature, the heat exchange effect between the flowing air and the surrounding air is poor. The end cap 7 is connected to the cooling water pipe. Since the inner side of the pipe body 901 is provided with internal threads, the passing cooling water drives the pipe body 901 to rotate. The outer spiral blades 902 provided on the outer side of the pipe body 901 push the air flow inside the second channel, thereby promoting the air flow inside the second channel and the first channel. Heat exchange is carried out through the pipe body 901, improving the heat exchange effect and improving the heat dissipation effect on the rangefinder body 4.
