Detailed implementation mode

[0023] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] In an embodiment of the present utility model, a laser rainproof device is provided. The laser rainproof device includes a front cover 10, a rear cover 20 and a body 30. The body 30 has a receiving cavity 310 for receiving a laser emitter 60. The receiving cavity 310 forms a front opening and a rear opening for entering and exiting the receiving cavity 310 on the body 30. The front cover 10 can cover the front opening, and the rear cover 20 can cover the rear opening; the front cover 10 has a glass 110 to facilitate the formation of the optical path of the laser emitter 60.

[0027] According to the laser rainproof device in the above embodiments, please refer to Figures 1 - 3Since the laser emitter 60 is contained in the body 30, the body 30 has a front cover 10 and a rear cover 20, and the front cover 10 has a glass 110, the optical path of the laser emitter 60 is not blocked. Therefore, the laser rainproof device in the utility model can better protect the laser emitter 60 from being corroded by rain in the air. The implementation of the laser rainproof device in the utility model can achieve the purpose of better waterproofing of the laser emitter 60 in outdoor environments.

[0028] Generally speaking, the material of the body 30 is preferably aluminum alloy. The power of the laser emitter 60 is generally high, and it needs to dissipate heat. Aluminum alloy is a corrosion-resistant material with high thermal conductivity, which can meet the heat dissipation requirements of the laser emitter 60 and withstand the test of the outdoor environment.

[0029] Furthermore, a plurality of heat dissipation patterns may be provided on the surface of the main body 30 , thereby increasing the contact area of ​​the main body 30 with air and enhancing the heat dissipation effect of the main body 30 .

[0030] In some specific embodiments, the material of the glass 110 is fused silica.

[0031] Fused silica is an amorphous (glassy) silicon oxide (quartz, silica). It not only has many excellent properties of quartz glass, such as small thermal expansion coefficient, good thermal stability, good electrical insulation, and good chemical corrosion resistance.

[0032] It should be noted that the glass 110 needs to be a flat glass with uniform material distribution, otherwise it will produce a certain refraction deviation, which will cause a lot of errors in the fields of outdoor laser level instruments and affect the use of the laser transmitter.

[0033] In some specific embodiments, please refer to Figure 2 and Figure 3 , and also includes a sealing ring 40, which is arranged between the front cover 10 and the body 30.

[0034] In this embodiment, the sealing ring 40 can further enhance the sealing effect of the front cover 10 , thereby preventing the outside air from communicating with the air in the receiving cavity 310 .

[0035] In some specific embodiments, the front cover 10 is screwed to the body 30 , and a slot 120 is provided on the front cover 10 facing away from the body 30 . After an insert is inserted into the slot 120 , the insert can be screwed to make the rear cover 20 and the body 30 rotate relative to each other.

[0036] In this embodiment, since the front cover 10 and the body 30 are screwed, the clamping groove 120 is required to limit the front cover 10 so as to facilitate the relative rotation of the front cover 10 and the body 30. The function of the clamping groove 120 is equivalent to the straight groove on the straight screw.

[0037] Of course, the front cover 10 and the main body 30 can also be connected in other ways, such as snap connection and gluing, etc.

[0038] The insert is generally some tools, mainly key-connected to the front cover 10 through an insertion action, so as to drive the rotation of the front cover 10.

[0039] In some specific embodiments, the rear cover 20 is screwed to the main body 30. A rotation hole 210 is provided in the direction of the rear cover 20 facing away from the front cover 10. After the insert is inserted into the rotation hole 210, turning the insert can rotate to make the rear cover 20 and the main body 30 rotate relative to each other.

[0040] In this embodiment, screwing the rear cover 20 and the main body 30 together has another function. Since the lengths of the laser emitters 60 are different, the distance between the rear cover 20 and the laser emitter 60 can be continuously adjusted by screwing until the rear cover 20 abuts against the laser generator to limit the laser emitter 60. Generally, there are more than two rotation holes 210. At the same time, inserting tools into the rotation holes 210 can limit the rear cover 20, so as to rotate the main body 30 to realize the screwing of the main body 30 and the rear cover 20.

[0041] In order to further ensure the sealing between the rear cover 20 and the main body 30, a sealing ring 40 can be provided between the rear cover 20 and the main body 30 to enhance the sealing effect. Or, apply thread sealant to the connection between the rear cover 20 and the main body 30, so as to realize that the rear cover 20 can seal the main body 30.

[0042] Similarly, the insert here is also for the rear cover 20 to be able to rotate relative to the main body 30.

[0043] In some specific embodiments, the rear cover 20 also has a power supply hole 220 for passing through the power cord 610.

[0044] The laser emitter 60 is a high-energy-consuming product and generally does not come with a battery. Usually, it is powered by an external power supply. The power supply hole 220 is reserved on the rear cover 20, which can allow the power cord 610 to pass through. Or arrange other power supply interfaces, such as two-hole sockets, three-hole sockets or USB sockets, etc.

[0045] In some specific embodiments, please refer to Figure 2 and Figure 3 , a waterproof interface 50 is also provided. The waterproof interface 50 is arranged at the power supply hole 220.

[0046] In this embodiment, the waterproof interface 50 can further ensure the tightness of the receiving cavity 310. The waterproof interface 50 is a commonly used part in the field of cable connection and is widely used in outdoor electronic products.

[0047] Specifically, a Gleason joint can be adopted. The Gleason joint is a commonly used mechanical sealing method, also known as radial sealing. It is applicable to application scenarios where effective sealing and leakage prevention are required between high-speed rotating or moving components. Since the laser emitter 60 generally has a power cord 610, the Gleason joint can meet the rotational requirements of the power cord 610 and prevent the power cord 610 from being damaged due to twisting.

[0048] In some specific embodiments, it further includes a shock-proof layer 320, which is fixed to the inner wall of the body 30 and contacts the laser emitter 60.

[0049] The shock-proof layer 320 is generally made of a flexible material with elastic deformation such as sponge or rubber. Its main function is to limit the shaking of the laser emitter 60 in the receiving cavity 310.

[0050] In some specific embodiments, fixing holes 330 are provided on the outer side of the body 30 for fixing the laser rain-proof device.

[0051] In an outdoor environment, it is often necessary to fix the laser emitter 60. In this embodiment, the laser rain-proof device is fixed through the fixing holes 330, thereby indirectly achieving the purpose of fixing the laser emitter 60.

[0052] Generally speaking, other methods can also be adopted to fix the laser rain-proof device in the present utility model. For example, double-sided tape can be used to fix the laser rain-proof device and the outdoor device. Or, a snap-fastener method can be adopted to achieve the rapid installation of the laser rain-proof device.

[0053] In some specific embodiments, the body 30 has an installation plane 340 around the fixing holes 330.

[0054] In this embodiment, the body 30 is generally in the shape of a hollow cylinder, so the outer side of the body 30 is a circumferential surface, which is not convenient for fixing the body 30. At this time, having an installation plane 340 around the fixing holes 330 can facilitate the positioning of the fixing holes 330, thereby achieving the purpose of rapidly installing the laser rain-proof device.

[0055] Finally, it should be noted that the installation steps of the laser rain-proof device of the present utility model are as follows:

[0056] 1. Place the sealing ring 40 on the front cover 10 and then thread it with the body 30. A tool can be used to be inserted into the card slot 120 to rotate the body 30 or the front cover 10.

[0057] 2. Place the laser emitter into the receiving cavity 310.

[0058] 3. Guide the power cord 610 through the power hole 220, and then screw the rear cover 20 to the main body 30. Thread sealant can be applied if necessary. A tool can be inserted into the rotation hole 210 to rotate the rear cover 20 or the main body 30.

[0059] 4. Guide the power cord 610 through the waterproof interface 50, and then install the waterproof interface 50 at the power hole 220.

[0060] 5. Use bolts to screw into the fixing holes 330 to fix the laser rain protection device somewhere outdoors.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
