Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

The following disclosure provides many different embodiments or examples for implementing different features of the application. To simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

Before describing the technical solution of the present application, it is necessary to explain the following background of the invention of the present application.

It is common in the related art that the projection is performed by using a laser projector, and the stability of the support device for the laser projector mainly depends on the self weight of the support device. To obtain a high stability, the weight of the support device is usually configured to be heavy. The heavier support means obviously increase the mobility flexibility during the erection operation, i.e. it is decided that the self-weight of the support means is limited by the flexibility of the erection operation, and the support stability obtained is very limited. Particularly susceptible to external forces. Here, the external force may be generated by an operation touch of a button or a knob for operating the laser projector, or wind force applied to a construction site, or the like, or by an inadvertent collision of a third party, which may cause a slight shake of the laser projector, and may eventually cause the laser to be scattered or shifted in a long-distance transmission.

In view of the above-mentioned problems of insufficient erection stability due to the influence of external force in the related art, the present inventors have surprisingly proposed a supporting device for laser projection and a laser positioning apparatus. When erection of the laser instrument is to be performed, an operator preassembles the mounting member 200 and the first fastening member 300 on a base material surface (for example, a poured concrete surface), places the adjustment foot stand 120 on the base material surface, and inserts the mounting member 200 into the first mounting groove 121a and the first fastening member 300 into the second mounting groove 122 a. Then, the second fastening member 400 is simultaneously inserted into the mounting hole 200a of the mounting member 200 and the third mounting groove 130a of the laser emission base 130 to achieve the mounting of the laser emission base 130 on which the laser emitter 500 is placed at the adjustment foot stand 120, thereby conveniently completing the erection. Since the fixing of the supporting means to the base material surface is achieved by means of the mounting member 200 and the first fastening member 300, the supporting means can maintain a firm connection to the base material surface without significant shaking even if being touched by an external force, providing stability of the support. Therefore, the invention is created.

Referring to fig. 1, fig. 2 and fig. 3, a supporting device for laser projection according to an embodiment of the present application includes:

An adjusting foot stand 120, including a fixing plate 121 and at least one positioning element 122 fixedly disposed on the fixing plate 121, wherein the fixing plate 121 is provided with a first mounting groove 121a, and the positioning element 122 is provided with a second mounting groove 122 a; the first mounting groove 121a is used for inserting a mounting piece 200 pre-mounted on a base material surface, the second mounting groove 122a is used for inserting a first fastener 300 pre-mounted on the base material surface, and the mounting piece 200 is provided with at least one mounting hole 200 a;

at least one laser emitting base 130 having a third mounting groove 130a, the third mounting groove 130a being adapted to be fitted with the mounting hole 200a, so that a second fastening member 400 can be simultaneously inserted into the third mounting groove 130a and the mounting hole 200a, thereby mounting the laser emitting base 130 on the adjusting foot stand 120.

It should be noted that although reference is made herein to "a support device for laser projection" with "laser projection," this limitation is merely an exemplary illustration and does not constitute a limitation on the use of the support device of the present application. That is, any other apparatus similar to a laser projector, that is, an apparatus required to provide stable support, such as an apparatus with a camera function (a smart terminal, a video camera, a video recorder, etc.), is suitable for the supporting device of the present application. "to project with laser light" is to be understood as an expression of an environment of use. For convenience of description, the laser projector is used as an example hereinafter, and descriptions of other non-ground-polishing operations are omitted to avoid conciseness.

Please refer to fig. 2 again. As an implementation manner of the fixed disk 121, the fixed disk 121 includes an inner disk 1211 and an outer disk 1212 rotatably disposed on the inner disk 1211, and the first mounting groove 121a is opened on the inner disk 1211.

Thus, during installation, the positioning member 122 can be rotated relative to the inner disk 1211, that is, the first installation groove 121a is rotated relative to the second installation groove 122a, so as to adjust the angle posture of the first installation groove 121a relative to the second installation groove 122a, and finally, the first fastening member 300 is inserted into the second installation groove 122a in a proper posture and the installation member 200 is inserted into the first installation groove 121a in a proper posture, so that the first fastening member 300 and the installation member 200 cannot be inserted in place (for example, incomplete insertion is not achieved, or the first fastening member 300 and the installation member 200 are not contacted with the groove walls of the first installation groove 121a and the second installation groove 122a sufficiently after insertion, etc.) due to the limitation of the preassembly position of the first fastening member 300 and the installation member 200.

It should be noted that the first fastener 300 and the mounting member 200 are previously mounted on the base material surface. Although the first fastening member 300 and the mounting member 200 are arranged according to the positions of the first and second mounting

grooves

121a and 122a of the adjusting horse 120 at the time of the pre-mounting operation. However, in this preliminary operation, it is generally necessary to open holes (i.e., pre-buried holes) in the substrate face. For some hard base material surfaces, such as strong concrete, the drilling operation usually requires a heavy manual drilling tool such as an electric pick or an electric hammer, which results in poor accuracy and reliability of the manual drilling, and inevitably generates certain errors, which may result in that the first fastening member 300 and the mounting member 200 cannot be completely inserted into the first mounting groove 121a and the second mounting groove 122a after being embedded into the embedded holes of the base material surfaces.

Here, it should be appreciated that the implementation structure of the rotatable arrangement may be a bearing, a bushing, or the like. As regards the manner of mounting these rotatable parts, it is common knowledge and will not be described again.

The number of the positioning members 122 can be selected according to actual needs, and the number of the positioning members 122 can be a plurality, such as three as shown in fig. 1, based on a better fixing effect on the fixing disc 121. A plurality of positioning members 122 may be arranged on the fixed disk 121 at uniform angular intervals.

As one implementation manner of the positioning member 122, the positioning member 122 includes a telescopic supporting rod 1221 and an installation seat disposed at an end of the supporting rod 1221, and the second installation groove 122a is opened in the installation seat.

Here, the telescopic supporting rod 1221 is configured such that the distance between the second mounting groove 122a with respect to the first mounting groove 121a is adjusted to ensure that the position of the second mounting groove 122a is better aligned with the first fastening member 300 pre-mounted on the base material surface, thereby improving the insertion thoroughness of the first fastening member 300 into the second mounting groove 122 a.

It should be noted that the reason why the insertion of the first fastener 300 into the second mounting groove 122a does not completely occur has been discussed previously.

For the telescopic implementation structure of the supporting rod 1221, any form known in the art may be used, such as a telescopic rod of an umbrella or a telescopic rod of a selfie stick, etc.

As a more convenient implementation, the retractable implementation is an adjusting solenoid 1222. Specifically, the positioning member 122 further includes an adjusting coil 1222 disposed on the supporting rod 1221, and the adjusting coil 1222 is used for installing at least two segments constituting the supporting rod 1221.

Here, the term "at least two segments for constituting the strut 1221" may be two segments as shown in fig. 1, or a plurality of segments, etc.

The adjusting screw 1222 is a pipe having two screw parts, wherein the two

screw parts

210 and 310 are respectively provided for the screw connection of the ends of two sections of the support rod 1221. Thus, when the telescopic adjustment is performed, one of the two sections of the adjusting rod 1221 is screwed, so as to adjust the length of the rod 1221 extending into the threaded portion, thereby achieving the length adjustment.

As for the connection manner of the positioning member 122 and the fixed disk 121, it may be an insertion connection manner so as to facilitate the detachment and installation of the positioning member 122 from the fixed disk 121, where the easy detachment and installation of the positioning member 122 and the fixed disk 121 can greatly improve the operation convenience of the insertion and installation of the second mounting groove 122a and the first fastening member 300, so as to prevent the fixing of the fixed disk 121 from causing a snag on the positioning rod and hindering the alignment of the second mounting groove 122a on the first fastening member 300 after the fixed disk 121 has been fixed on the base material surface by the mounting member 200. Thus, in the implementation manner of inserting the positioning element 122 into the fixed disk 121, after the second mounting groove 122a is aligned with the first fastening element 300 and the mounting element 200 is aligned with the first mounting groove 121a, the fixed disk 121 and the positioning element 122 are inserted and combined, so that the smoothness of the whole operation process is improved.

In an exemplary embodiment, the fixing plate 121 is provided with a horizontal direction indicator 123 to indicate the levelness or verticality of the fixing plate 121 with respect to the surface of the base material, thereby ensuring the levelness or verticality of the laser emitting base 130 after being assembled to the adjusting foot stand 120.

The horizontal orientation indicator 123 may be in the form of a bubble level, or a level gauge, or the like.

Please refer to fig. 3. As for the implementation manner of the laser emitting base 130, it may include a base body 132, and the base body 132 is opened with the third mounting groove 130 a. The configuration number and the configuration vertical position relationship of the third mounting grooves 130a can be, for example, two in fig. 3, that is, one in the middle and one in the lower, according to the actual requirement.

The base body 132 may further be provided with a placement structure 131 for placing the laser emitter 500.

Please refer to fig. 4. As an implementation of the mounting device 200, the mounting device 200 includes screw-coupling

portions

210 and 310 for screw-coupling to the surface of the substrate, and a coupling portion 220 having the mounting hole 200 a.

Thus, the arrangement of the threaded portions 210,310 of the mounting member 200 facilitates the mounting robustness of the pre-buried holes of the mounting member 200 on the substrate surface, reducing the risk of hole-dropout.

Of course, the mounting member 200 may be other conventional bolts or expansion bolts.

In order to reduce the interference of the connection part 220 of the mounting member 200 with the insertion of the second fastening member 400 when the connection part 220 enters the pre-buried hole, the mounting member 200 may further include a protrusion part 240,340 for connecting the connection part 220 and the

screw connection parts

210, 310.

The protruding

portions

240 and 340 prevent the connecting portion 220 from being inserted into the pre-buried holes by the protruding positions thereof, thereby ensuring that the connecting portion 220 is exposed on the surface of the base material and preventing the connecting portion 220 from being hidden by the pre-buried holes.

Please refer to fig. 5. As an implementation manner of the first fastening member 300, a roller 1223 is disposed in the second mounting groove 122a, the first fastening member 300 includes screw-coupling

portions

210 and 310 to be screw-coupled to the surface of the substrate, and a retainer ring 320 to be fixedly coupled to the screw-coupling

portions

210 and 310, and the retainer ring 320 is engaged with the roller 1223.

In this implementation manner of the first fastening member 300, the snap ring 320 only needs to be hooked on the outer surface of the roller 1223 during the insertion and engagement operation of the second mounting groove 122a and the first fastening member 300. The threaded portion of the first fastener 300 facilitates the installation firmness of the pre-buried hole of the first fastener 300 on the surface of the base material, and reduces the risk of hole falling.

In order to reduce the interference of the insertion of the snap ring 320 of the first fastening member 300 into the pre-buried hole and the second mounting groove 122a, the first fastening member 300 may further include a protrusion portion 240,340 connecting the snap ring 320 and the screw-

coupling portion

210, 310.

The protruding

portions

240 and 340 prevent the snap ring 320 from being inserted into the pre-buried holes by the protruding positions, so that the snap ring 320 of the first fastening member 300 is exposed on the surface of the base material, and the snap ring 320 is prevented from being hidden by the pre-buried holes.

Please refer to fig. 6. The second fastening member 400 may be a connecting member such as a pin or a pin. As an implementation manner, please refer to fig. 6, which includes an insertion portion 420 and an operation portion 440, wherein the operation portion 440 is used for being held by hand or by a tool during an insertion operation, and the insertion portion 420 is used for being inserted into the third mounting groove and the mounting hole 200a at the same time.

The insertion portion 420 may be rounded to reduce resistance to insertion, facilitating insertion. The handle portion 440 may be square to facilitate hand-holding or tool-holding.

The embodiment further provides a laser positioning apparatus, which includes the supporting device as described above, and two laser transmitters 500 disposed on the supporting device, where the two laser transmitters 500 are respectively disposed on two laser emitting bases and are respectively used to generate vertical laser and horizontal laser.

Therefore, through the two laser transmitters 500 of the laser in the vertical direction and the laser in the horizontal direction, the laser emission of the horizontal plane and the vertical plane is realized, and the comprehensiveness and the rapidness of laser measurement are improved.

Here, the specific structure of the placement of the laser transmitter 500 on the supporting device may be a fixing member such as a holder of a selfie stick or other holder fixing device.

It should be noted that the laser emitter 500 may be of a type commonly used in the art, and the specific structure thereof does not affect the effect of the support device described above. In view of this, the detailed structure of the laser transmitter 500 will not be described.

While the invention has been described with reference to specific preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
