Description

Technical Field

[0001] The invention relates to the technical field of laser line projectors, in particular to a laser line projector for surveying and mapping. Background Art

[0002] The laser line projector battery pack currently used in the market is not firmly installed and is easy to fall when connected to the host. There is no anti-falling and easy-to-disassemble device, or there is a battery pack limit device, but the structure is complicated and inconvenient to use, which affects the overall experience of the user.

[0003] The weight assembly in the laser line projector is the core component, which swings through two mutually perpendicular shafts with bearings. This structure ensures that the weight can swing freely forward, backward, left and right, and always remain in a vertical state. However, it is precisely because of this structural setting that once it falls, the weight assembly will shake and collide, which will cause damage to the internal components of the laser line projector. For this reason, we have launched a laser line projector for surveying and mapping. Summary of the invention

[0004] The purpose of the present invention is to provide a laser line projector for surveying and mapping to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A surveying laser line projector, comprising an upper shell and a battery pack, wherein after the battery pack is inserted downward into a mounting slot at the rear of the upper shell, an output conductive sheet at the bottom of the inner side of the battery pack is plugged and connected with a powered conductive sheet at the bottom of the mounting slot, and a limit button assembly at the top of the mounting slot is popped out and stuck on the top of the battery pack;

The connecting column at the upper end of the annular rotating seat extends through the arc groove on the annular end cover and is inserted into the U-shaped seat of the conductive component.

[0011] When the sliding switch is pushed forward, the square conductive sheet on the conductive assembly is no longer in contact with the corresponding circular conductive sheet, and the battery pack no longer supplies power to the laser light assembly. At the same time, the annular rotating seat is driven to rotate clockwise, so that the inner end of the buffer clamping assembly is clamped on the bottom side of the heavy hammer assembly, thereby fixing the heavy hammer assembly.

[0012] When the sliding switch is pushed backward, the square conductive sheet on the conductive assembly contacts the corresponding circular conductive sheet, and the battery pack supplies power to the laser light group. At the same time, it drives the annular rotating seat to rotate counterclockwise, so that the inner end of the buffer clamping assembly no longer clamps the bottom side of the weight assembly, thereby releasing the weight assembly.

[0013] Preferably, a buckle block is provided on the inner side of the battery pack, and protruding blocks for being clamped on the side edges of the buckle block are provided on both sides of the mounting groove.

[0014] Preferably, a button slot is provided at the top of the installation slot, and buckle slots are provided at the bottom of both sides of the button slot;

[0021] The weight assembly comprises a top column and a bottom column whose lower end is fixed by a connecting platform, and a second pin shaft is fixed to the left and right outer sides of the top column, and the second pin shaft is inserted into a second pin hole on the annular connecting seat;

[0022] The laser light group includes a top laser light fixed on the upper end of the top column and a side laser light fixed on the side of the connecting platform, and a counterweight block is also fixed on the side of the connecting platform.

[0023] Preferably, the bottom column extends into the bottom tube, and magnet blocks are evenly distributed on the sides of the bottom of the bottom tube.

[0024] Preferably, L-shaped grooves are provided on both sides of the top of the reserved groove, and the buffer clamping assembly includes a movable plate slidably connected to the corresponding two groups of L-shaped grooves, a sliding seat fixed at the bottom of the movable plate and slidably connected to the reserved groove, an abutment wheel movably connected to the middle of the outer end of the sliding seat through a convex plate, a connecting cylinder fixed in the middle of the inner end of the movable plate, a piston slidably connected inside the connecting cylinder, and an arc-shaped clamping seat connected to the middle of the inner end of the piston through a support rod;

[0025] The abutting wheel abuts against the corresponding slope surface.

[0026] Preferably, a sealing cover is fixed to the outer end of the connecting cylinder, the support rod passes through and extends out of the sealing cover, and a first buffer spring is fixed to the inner end of the middle part of the piston;

[0027] The outer side walls at both ends of the movable plate are connected to the inner end root of the L-shaped groove through a second buffer spring.

[0028] Preferably, the U-shaped seat is fixed to the middle of the inner side of the sliding switch;

[0029] The conductive component includes a metal limiting rod fixed at the inner end of the U-shaped seat, and both ends of the metal limiting rod extend through the inner end of the vertical plate.

[0030] Preferably, the square conductive sheets are respectively located in front of the corresponding vertical plates, and the square conductive sheets are fixed by metal connecting plates and metal limiting rods.

[0031] Compared with the prior art, the present invention has the following beneficial effects: the present invention can realize the rapid installation or removal of the battery pack through the limit button assembly, and after the battery pack is installed, the limit button assembly limits the upper end surface of the battery pack, at this time, whether the upper shell part or the battery pack part is held, the upper shell and the battery pack will not be separated, so that the battery pack and the upper shell are installed more firmly;

[0032] When closed, when the sliding switch is pushed forward, the square conductive sheet on the conductive component no longer contacts the corresponding circular conductive sheet, and the battery pack no longer supplies power to the laser light assembly, thereby increasing the service life of the battery pack. At the same time, the annular rotating seat is driven to rotate clockwise, so that the inner end of the buffer clamping component is clamped on the bottom side of the heavy hammer component, thereby fixing the heavy hammer component and preventing the heavy hammer component from shaking and colliding in the inner cavity of the upper shell when falling, thereby avoiding damage to components in the inner cavity of the upper shell;

[0033] When turned on, when the sliding switch is pushed backward, the square conductive sheet on the conductive component contacts the corresponding circular conductive sheet, and the battery pack supplies power to the laser light group. At the same time, the annular rotating seat is driven to rotate counterclockwise, so that the inner end of the buffer clamping component no longer clamps the bottom side of the heavy hammer component, thereby releasing the heavy hammer component. This can improve the working efficiency of the laser line projector and facilitate the laser line projector to quickly turn on to the working state;

[0034] After the weight assembly is released, the inner end of the arc-shaped clamp seat always extends to the inner side of the bottom tube, which prevents the laser line projector from accidentally falling during use. The weight assembly shakes, and the bottom column of the weight assembly first contacts the arc-shaped clamp seat, so that the arc-shaped clamp seat drives the piston to further retract into the connecting tube through the support rod. At this time, since the first buffer spring is fixed to the inner end of the middle part of the piston, the first buffer spring plays a buffering role, thereby further playing a buffering role for the shaking of the bottom column, preventing the weight assembly from shaking and colliding in the inner cavity of the upper shell, and avoiding damage to components in the inner cavity of the upper shell.

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Example:

[0058] See also Figure 1-20 , the present invention provides a technical solution:

[0059] A surveying and mapping laser line projector comprises an upper shell 1 and a battery pack 5. A leg frame 4 is provided at the bottom of the upper shell 1. A prism cover 2 is provided at the top and side of the upper shell 1. A top laser light 1403 extends into the top prism cover 2, and a side laser light 1402 extends into the corresponding side prism cover 2.

[0060] After the battery pack 5 is inserted downward into the mounting slot 103 at the rear of the upper housing 1, the output conductive sheet 502 at the bottom of the inner side of the battery pack 5 is plugged and connected with the energized conductive sheet 101 at the bottom of the mounting slot 103, and the limit button assembly 6 at the top of the mounting slot 103 pops out and is stuck on the top of the battery pack 5;

[0061] A buckle block 501 is provided inside the battery pack 5, and protrusions 102 are provided on both sides of the mounting groove 103 for being clamped on the sides of the buckle block 501. This arrangement allows the battery pack 5 to be clamped with the mounting groove 103 at the rear of the upper housing 1 after the bottom of the battery pack 5 is placed into the mounting groove 103 and the battery pack 5 is pressed downward, so that the battery pack 5 can be quickly installed.

[0062] A button slot 104 is provided at the top of the installation slot 103, and buckle slots 105 are provided at the bottom of both sides of the button slot 104;

[0063] The limit button assembly 6 includes a limit button 601 and a limit seat 602;

[0064] A button spring 6011 is fixed inside the limit button 601, two sets of limit plates 6012 are symmetrically arranged at the lower end of the limit button 601, a positioning pin 106 is arranged at the upper part of the button slot 104, and the button spring 6011 is sleeved on the positioning pin 106;

[0065] like Figure 5 As shown, the two sides of the limit seat 602 are symmetrically provided with side buckles 6022 that are snapped into the buckle grooves 105. Such a setting is conducive to the rapid installation, disassembly and replacement of the limit seat 602;

[0066] A U-shaped groove 6021 for clamping the limiting plate 6012 is provided on the inner side of the side buckle 6022, so that after the button spring 6011 pops the rear part of the limiting button 601 out of the button groove 104, the limiting button 601 can be limited to prevent the limiting button 601 from falling off after completely popping out of the button groove 104.

[0067] The upper shell 1 plays a guiding and supporting role during the forward and backward movement of the limit button 601 , facilitates the positioning of the button spring 6011 , and constrains the travel range of the limit button 601 .

[0068] The limit button 601 is also provided with a positioning pin 106 inside, so that the front and rear ends of the button spring 6011 are respectively sleeved on the corresponding positioning pins 106, which facilitates the installation of the button spring 6011.

[0069] The two ends of the limit seat 602 rely on elastic deformation to clip the side buckles 6022 at both ends into the buckle groove 105, and rely on the U-shaped groove 6021 to limit the limit plate 6012, so as to limit the limit button 601 and prevent the limit button 601 from falling.

[0070] A base 8 is fixed to the bottom of the inner cavity of the upper shell 1, and an annular end cover 7 is fixed to the upper end of the base 8. A weight assembly 14 is installed on the bracket assembly at the upper end of the annular end cover 7 through a cross-axis swing frame 11, and the cross-axis swing frame 11 realizes the front and back left and right swing of the weight assembly 14;

[0071] The bracket assembly includes a column 9 fixed to the upper end of the annular end cover 7 and a support 10 fixed to the top of the column 9;

[0072] The cross-axis swing frame 11 includes an annular connecting seat 1101 and a first connecting pin 1102 fixed to the front and rear outer sides of the annular connecting seat 1101. The first connecting pin 1102 is inserted into the first pin hole 1001 on the support 10.

[0073] The weight assembly 14 includes a top column 1406 and a bottom column 1407 whose lower end is fixed by a connecting platform 1405. A second pin shaft 1404 is fixed to the left and right outer sides of the top column 1406. The second pin shaft 1404 is inserted into a second pin hole 1103 on the annular connecting seat 1101.

[0074] The bottom column 1407 extends into the bottom tube 802, and magnet blocks 803 are evenly spaced on the bottom side of the bottom tube 802. Under the suction of the magnet blocks 803 on the bottom column 1407, the weight assembly 14 swings back and forth and then stops immediately, so that the weight assembly 14 stops quickly, so that the laser line projector can quickly enter the use state;

[0075] The laser light assembly includes a top laser light 1403 fixed on the upper end of a top column 1406 and a side laser light 1402 fixed on the side of a connecting platform 1405 , and a counterweight block 1401 is also fixed on the side of the connecting platform 1405 .

[0076] The base 8 includes a bottom tube 802 fixed to the bottom of the inner cavity of the upper shell 1 and an annular seat 801 connected to the outer side of the top of the bottom tube 802. An annular rotating seat 15 is provided in an annular groove 804 on the annular seat 801. A buffer clamping assembly 12 is provided in a reserved groove 805 provided at equal intervals inside the annular groove 804.

[0077] L-shaped grooves 806 are provided on both sides of the top of the reserved groove 805, and the buffer clamping assembly 12 includes a moving plate 1201 slidably connected to the corresponding two groups of L-shaped grooves 806, a sliding seat 1206 fixed at the bottom of the moving plate 1201 and slidably connected to the reserved groove 805, a supporting wheel 1208 movably connected to the middle of the outer end of the sliding seat 1206 through a convex plate 1207, a connecting cylinder 1202 fixed at the middle of the inner end of the moving plate 1201, a piston 1210 slidably connected inside the connecting cylinder 1202, and an arc-shaped clamping seat 1205 connected to the middle of the inner end of the piston 1210 through a support rod 1204;

[0078] A cover 1203 is fixed to the outer end of the connecting cylinder 1202, a support rod 1204 extends through the cover 1203, and a first buffer spring 1209 is fixed to the inner end of the middle part of the piston 1210;

[0079] The outer side walls at both ends of the moving plate 1201 are connected to the inner end root of the L-shaped groove 806 through the second buffer spring 807 .

[0080] The inner end of the buffer clamping assembly 12 extends into the annular seat 801 , and the outer end of the buffer clamping assembly 12 abuts against the corresponding slope surface 1501 inside the annular rotating seat 15 , that is, the abutting wheel 1208 abuts against the corresponding slope surface 1501 surface.

[0081] The upper housing 1 is slidably connected with a sliding switch 3, and the inner side of the sliding switch 3 is provided with a conductive component 13 extending into the inner cavity of the upper housing 1. The connecting column 1502 at the upper end of the annular rotating seat 15 extends through the arc groove 701 on the annular end cover 7 and is inserted into the U-shaped seat 301 of the conductive component 13;

[0082] The annular end cover 7 is also provided with vertical plates 702 located on both sides of the arc groove 701, and a circular conductive sheet 704 is fixed in the inner groove 705 on the front end surface of the vertical plate 702;

[0083] One circular conductive sheet 704 (i.e., the circular conductive sheet 704 at the rear) is electrically connected to the corresponding powered conductive sheet 101 (the powered conductive sheet 101 at the negative pole) through a wire, and another circular conductive sheet 704 (i.e., the circular conductive sheet 704 at the front) is electrically connected to the corresponding laser light group (i.e., the top laser light 1403 and the side laser light 1402) on the weight assembly 14 through a wire, and the laser light group is then connected in series with the powered conductive sheet 101 at the positive pole through a wire;

[0084] In this way, when the slide switch 3 is pushed forward to Fig.10 and 18 In the state shown, the square conductive sheet 1303 is out of contact with the front and rear two groups of circular conductive sheets 704, so that the top laser light 1403 and the side laser light 1402 are no longer connected to the energized conductive sheet 101, so that the battery pack 5 no longer supplies power to the laser light group;

[0085] When the slide switch 3 is pushed back to Fig.19 and 20 In the state shown, the square conductive sheet 1303 contacts the front and rear two groups of circular conductive sheets 704, so that the top laser light 1403 and the side laser light 1402 are connected to the powered conductive sheet 101, and the battery pack 5 supplies power to the laser light group.

[0086] like Fig.10 , 16 As shown in 19, the U-shaped seat 301 is fixed to the middle of the inner side of the slide switch 3;

[0087] The conductive component 13 includes a metal limiting rod 1301 fixed to the inner end of the U-shaped seat 301 , and both ends of the metal limiting rod 1301 extend through the inner end of the vertical plate 702 .

[0088] The square conductive sheets 1303 are respectively located in front of the corresponding vertical plates 702 , and the square conductive sheets 1303 are fixed by using metal connecting plates 1302 and metal limiting rods 1301 .

[0089] When the sliding switch 3 moves forward and backward along the side surface of the upper housing 1, the metal limit rod 1301 also moves forward and backward along the vertical plate 702. This arrangement can ensure the horizontal movement of the sliding switch 3, so that the movement of the sliding switch 3 is smooth and stable.

[0090] When the sliding switch 3 moves forward and backward, the connecting column 1502 moves accordingly along the U-shaped through groove inside the U-shaped seat 301 , so that the U-shaped seat 301 drives the annular rotating seat 15 to rotate counterclockwise and clockwise through the connecting column 1502 .

[0091] The through connection between the metal limit rod 1301 and the vertical plate 702 has a certain damping, and the connection between the sliding switch 3 and the side surface of the upper shell 1 also has a certain damping, so that after the sliding switch 3 moves back and forth, the sliding switch 3 will not reset, thereby avoiding unnecessary movement and reset of the conductive component 13 and the annular rotating seat 15.

[0092] When the slide switch 3 is pushed forward, the conductive component 13 disconnects the laser light group from the energized conductive sheet 101, so that the battery pack 5 no longer supplies power to the laser light group. At the same time, the inner end of the buffer clamping component 12 is clamped on the bottom side of the weight component 14, and after the weight component 14 is fixed, it is prevented from shaking and hitting in the inner cavity of the upper shell 1 when it falls, thereby avoiding damage to the components in the inner cavity of the upper shell 1.

[0093] That is, when the slide switch 3 is pushed forward, the square conductive sheet 1303 on the conductive component 13 is no longer in contact with the corresponding circular conductive sheet 704, and the battery pack 5 no longer supplies power to the laser light assembly. At the same time, the annular rotating seat 15 is driven to rotate clockwise, so that the inner side end of the buffer clamping component 12 is clamped on the bottom side of the heavy hammer component 14, thereby fixing the heavy hammer component 14;

[0094] When the slide switch 3 is pushed backward, the conductive component 13 is connected to the power-carrying conductive sheet 101 through the laser light group, so that the battery pack 5 supplies power to the laser light group. At the same time, the inner end of the buffer clamping component 12 no longer clamps the bottom side of the weight component 14, so that the weight component 14 is released. After the weight component 14 swings back and forth and left and right, it stops, so as to achieve the level of the laser light group on the weight component 14.

[0095] That is, when the sliding switch 3 is pushed backward, the square conductive sheet 1303 on the conductive component 13 contacts the corresponding circular conductive sheet 704, and the battery pack 5 supplies power to the laser light group. At the same time, it drives the annular rotating seat 15 to rotate counterclockwise, so that the inner end of the buffer clamping component 12 no longer clamps the bottom side of the weight component 14, thereby releasing the weight component 14.

[0096] Specifically, when in use, the battery pack 5 is fitted with the mounting groove 103 at the rear of the upper housing 1, the bottom of the battery pack 5 is placed into the mounting groove 103, and the battery pack 5 is pressed downward so that the buckle block 501 inside the battery pack 5 is engaged with the protruding blocks 102 on both sides of the mounting groove 103, thereby realizing the rapid installation of the battery pack 5;

[0097] When the battery pack 5 is pressed downward, the battery pack 5 exerts a forward pressure on the limit button 601, and the limit button 601 overcomes the elastic force of the button spring 6011, so that the limit button 601 completely enters the button slot 104, and the button spring 6011 is in a compressed state.

[0098] When the battery pack 5 drops to the lowest position, the upper part of the battery pack 5 no longer rests against the rear end of the limit button 601. At this time, under the elastic force of the button spring 601, the rear part of the limit button 601 pops out of the button slot 104, and the limit button 601 is stuck on the top of the limit button 601 to limit the upper end surface of the battery pack 5. At this time, no matter whether the upper shell 1 or the battery pack 5 is held by hand, the upper shell 1 and the battery pack 5 will not be separated.

[0099] After the battery pack 5 is installed in place, the output conductive sheet 502 at the bottom inner side of the battery pack 5 is plugged into and connected with the powered conductive sheet 101 at the bottom of the installation slot 103, that is, the powered conductive sheet 101 of the positive pole is inserted into the output conductive sheet 502 of the positive pole, and the powered conductive sheet 101 of the negative pole is inserted into the output conductive sheet 502 of the negative pole.

[0100] When the battery pack 5 needs to be removed, the limit button 601 is first pressed, and the limit button 601 is fully pressed into the button slot 104 , and then the battery pack 5 is gently pushed upward to remove the battery pack 5 .

[0101] In the initial state, the slide switch 3 is in the front off position. Fig.10 and 18 In the state shown, the square conductive sheet 1303 is out of contact with the front and rear two groups of circular conductive sheets 704, so that the top laser light 1403 and the side laser light 1402 are no longer connected to the energized conductive sheet 101, so that the battery pack 5 no longer supplies power to the laser light group;

[0102] At the same time, the U-shaped seat 301 drives the annular rotating seat 15 to rotate clockwise through the connecting column 1502, and the abutting wheel 1208 gradually rolls toward the inner surface of the slope surface 1501. The slope surface 1501 pushes the abutting wheel 1208 inward, so that the movable plate 1201 moves toward the inner end root along the L-shaped groove 806. The movable plate 1201 gradually compresses the second buffer spring 807. At this time, the arc clamp seat 1205 further extends inward until the arc clamp seat 1205 completely clamps and fixes the bottom column 1407.

[0103] When starting to use, the slide switch 3 is in the on position at the rear. Fig.19 and 20 In the state shown, the square conductive sheet 1303 is in close contact with the front and rear two groups of circular conductive sheets 704, so that the top laser light 1403 and the side laser light 1402 are connected to the powered conductive sheet 101, and the battery pack 5 supplies power to the laser light group;

[0104] At the same time, the U-shaped seat 301 drives the annular rotating seat 15 to rotate counterclockwise through the connecting column 1502, and the abutting wheel 1208 rolls down along the inner surface of the slope surface 1501. At this time, under the elastic force of the second buffer spring 807 on the movable plate 1201, the movable plate 1201 moves to its outer end along the L-shaped groove 806 to reset, and the arc-shaped clamping seat 1205 retracts outward until the arc-shaped clamping seat 1205 is no longer in contact with the side of the bottom column 1407;

[0105] At this time, as the bottom column 1407 is released, the entire weight assembly 14 swings back and forth and left and right under the action of gravity until the entire weight assembly 14 is stationary, so as to achieve the level of the laser light group on the weight assembly 14;

[0106] The laser light generated by the top laser light 1403 passes through the top prism cover 2, and the laser light generated by the side laser light 1402 passes through the corresponding side prism cover 2.

[0107] And when the arc clamp seat 1205 is not in contact with the side of the bottom column 1407, the inner end of the arc clamp seat 1205 always extends into the inner side of the bottom tube 802, so as to prevent the laser line projector from accidentally falling during use and the weight assembly 14 from shaking. The bottom column 1407 of the weight assembly 14 first contacts the arc clamp seat 1205, so that the arc clamp seat 1205 drives the piston 1210 to further retract into the connecting tube 1202 through the support rod 1204. At this time, since the first buffer spring 1209 is fixed to the inner end of the middle part of the piston 1210, the first buffer spring 1209 plays a buffering role, thereby further playing a buffering role for the shaking of the bottom column 1407, preventing the weight assembly 14 from shaking and colliding in the inner cavity of the upper shell 1, and avoiding damage to the components in the inner cavity of the upper shell 1.

[0108] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
