Description

Technical Field

[0001] The present application relates to the technical field of auxiliary tools for fire detection equipment, and particularly to a laser rangefinder bracket. Background Art

[0002] A laser rangefinder is a commonly used measuring instrument in modern measurement work and is increasingly widely used in the field of fire detection. It can quickly measure key data such as the height and distance of buildings. During operation, in order to improve the accuracy and stability of measurement, a laser rangefinder is usually equipped with a bracket for support and fixation.

[0003] Existing laser rangefinder brackets usually include a platform for placing the laser rangefinder and several feet. For example, referring to the Chinese patent document with the publication number CN218295180U, a laser rangefinder bracket is disclosed, which includes an occlusion member, a placement rack, and feet. The placement rack is rotatably connected to the occlusion member, and three feet are arranged on the occlusion member to support the occlusion member.

[0004] Regarding the above related technologies, when the laser rangefinder bracket is used in outdoor complex environments, the bottom of the feet is likely to come into contact with dirty substances such as soil, dust, and oil stains. Especially in construction sites or undeveloped wild areas, the ground conditions are poor, and the feet will inevitably be contaminated during the placement process. After the measurement work is completed, the laser rangefinder bracket often needs to be temporarily placed in the trunk, back seat of the vehicle, or other relatively clean places. In the case where the user does not have cleaning tools, when placing the bracket, the dirt on the feet is likely to rub against the vehicle interior or other clean placement surfaces, causing secondary pollution, which not only affects the cleanliness of the placement point but also may make the stains difficult to clean, bringing an additional cleaning burden to the user. Summary of the Invention

[0005] In order to prevent the dirt on the feet from causing secondary pollution to the placement point when the bracket is stored, the present application provides a laser rangefinder bracket.

[0006] The present application provides a laser rangefinder bracket, adopting the following technical solutions: A laser rangefinder bracket, comprising: A main shaft; An installation platform, arranged at one end of the main shaft; An occlusion member, including a chassis and a fence; the chassis is fixedly arranged at the end of the main shaft away from the installation platform, the fence is arranged on the chassis and is evenly spaced circumferentially along the main shaft; and the fence forms a receiving cavity with an opening facing the installation platform; The support assembly includes a main hinge seat, a secondary hinge seat, a support leg, and a connecting rod; both the main hinge seat and the secondary hinge seat are sleeved on the main shaft, capable of moving circumferentially and axially along the main shaft, and the secondary hinge seat is located between the main hinge seat and the shielding member; one end of the support leg is hinged to the main hinge seat, and the support legs correspond to the enclosures one by one; the connecting rods correspond to the support legs one by one, and the connecting rods are hinged between the secondary hinge seat and the corresponding support leg. Wherein, the support assembly has usage states, a retracted state, and a stored state corresponding to itself and realized in sequence; when the support assembly is in the usage state, the support legs expand outwards in a direction away from the installation platform; when the support assembly moves to the retracted state, the main hinge seat moves in a direction away from the secondary hinge seat to drive the support legs to move parallel to the main shaft; when the support assembly moves to the stored state, the main hinge seat and the secondary hinge seat rotate relative to the main shaft together and then move closer to the chassis to drive the ends of the support legs away from the installation platform into the accommodation cavities of the corresponding enclosures.

[0007] By adopting the above technical solution, through the three-state switching design of the support assembly, it is realized that the support legs completely enter the accommodation cavities of the enclosures in the stored state. It can prevent dirt such as mud and oil stained on the support legs outdoors from easily contacting the vehicle interior or the cleaning surface, reduce the problem of secondary pollution, and at the same time improve the overall structural compactness of the bracket during storage, facilitating carrying and storage.

[0008] Optionally, the inner wall of the secondary hinge seat has a limiting protrusion, and the main shaft has a first limiting groove and a second limiting groove for the limiting protrusion to slide; the first limiting groove extends along the axial direction of the main shaft, the second limiting groove is located at one end of the first limiting groove away from the chassis, and the second limiting groove extends along the circumferential direction of the main shaft; When the support assembly is in the retracted state, the limiting protrusion is located in the second limiting groove; when the support assembly is in the stored state, the limiting protrusion abuts against one end of the first limiting groove away from the second limiting groove.

[0009] By adopting the above technical solution, the movement of the limiting protrusion in the first limiting groove and the second limiting groove can guide the movement of the secondary hinge seat.

[0010] Optionally, the inner wall of the main hinge seat has a guiding protrusion, and the main shaft has a first guiding groove, a second guiding groove, and a third guiding groove for the guiding protrusion to slide and sequentially communicate; both the first guiding groove and the second guiding groove extend along the axial direction of the main shaft, the second guiding groove extends along the circumferential direction of the main shaft, and the second guiding groove communicates between one end of the first guiding groove and the second guiding groove close to the installation platform; When the support assembly switches between the use state and the recovery state, the guide protrusion slides in the third guide groove; when the support assembly moves from the recovery state to the storage state, the guide protrusion slides from the third guide groove into the second guide groove and then into the first guide groove.

[0011] By adopting the above technical solution, the linkage between the guide protrusion and the three guide grooves realizes the smooth switching of the support assembly between different states. The first and third guide grooves control the linear movement of the main hinge seat, and the second guide groove guides the rotational movement, so that the movement trajectory of the support leg during the unfolding, retracting and storage process is controllable, and the operation is more convenient.

[0012] Optionally, the support leg comprises an outer rod and an inner rod, the outer rod is hinged on the main hinge seat, the inner rod is slidably inserted into the outer rod along the length direction of the outer rod, and the end of the inner rod away from the main hinge seat is a spike end, and a reset elastic member is provided between the outer rod and the inner rod, and the reset elastic member is used to give the inner rod an elastic force to retract the spike end into the outer rod; The support assembly also includes a base sleeved on the main shaft, the base moves axially on the main shaft along the main shaft, and the base is coaxially rotatably connected to the main hinge seat; the base is communicated with the main hinge seat, and a linkage assembly is provided between the base and the main hinge seat, and when the guide protrusion slides from an end of the second guide groove close to the first guide groove to an end of the second guide groove close to the third guide groove, the linkage assembly pushes the inner support rod to move relative to the outer rod, so that the spike end extends out of the outer rod.

[0013] By adopting the above technical solution, the support leg adopts an inner and outer rod telescopic structure, and the spike end is automatically retracted through the reset elastic member. Combined with the cooperation of the linkage component and the base, the spike end can be automatically retracted into the outer rod during the storage process, making it difficult for the spike end to scratch the user and hiding the dirt on the spike end. At the same time, the spike end can enhance the grip of the support leg on soft ground when in use, improving the stability of the bracket.

[0014] Optionally, the linkage component includes An abutment piece is axially movable in the main hinge seat along the main axis, the abutment piece corresponds to the inner support rod one by one, and one end of the inner support rod away from the spike end abuts against a side of the abutment piece away from the base; An auxiliary column extending axially in parallel with the main axis in the main hinge seat, and the abutment sheet is slidably sleeved on the auxiliary column; and A pressing seat, fixed in the base, corresponding to the contact piece one by one, and having a guide slope; When the main hinge seat rotates to drive the guiding convex position to move from one end of the second guiding groove close to the first guiding groove to one end close to the third guiding groove, the pressing seat gradually presses the abutting piece towards the direction away from the base through the guiding inclined surface, so as to drive the spiked end to extend out of the outer sleeve rod.

[0015] By adopting the above technical solution, the linkage assembly converts the rotational movement of the main hinge seat into the axial movement of the abutting piece through the cooperation of the guiding inclined surface of the pressing seat and the abutting piece, thereby pushing the inner support rod to extend out the spiked end.

[0016] Optionally, the abutting piece is arc-shaped with the arc opening facing the inner support rod, and the axis of the abutting piece is parallel to the rotation axis of the support leg.

[0017] By adopting the above technical solution, the arc-shaped abutting piece makes the displacement distance of the inner support rod relative to the outer sleeve rod small when the support leg rotates, improving the stability of the inner support rod.

[0018] Optionally, one end of the outer sleeve rod away from the main hinge seat is smooth. The main shaft has a fourth guiding groove and a fifth guiding groove for the guiding convex to slide. The fourth guiding groove communicates with the first guiding groove and extends along the circumferential direction of the main shaft, and the fourth guiding groove extends towards the direction away from the second guiding groove; the fifth guiding groove communicates with one end of the fourth guiding groove away from the first guiding groove, and the fifth guiding groove extends together with the third guiding groove; when the guiding convex slides to the fifth guiding groove, the spiked end remains in the state of being received in the outer sleeve rod.

[0019] By adopting the above technical solution, through the cooperation of the guiding convex with the fourth guiding groove and the fifth guiding groove, the support leg can keep the spiked end received in the outer sleeve rod during use to adapt to the ground that needs to prevent scratching.

[0020] Optionally, the depth of the first guiding groove is greater than the depths of the second guiding groove and the fourth guiding groove, and the guiding convex has a ball head plunger. When the guiding convex faces the first guiding groove, the ball head of the ball head plunger abuts into the first guiding groove.

[0021] By adopting the above technical solution, through the cooperation of the ball head plunger and the first guiding groove, it can give a prompt when the guiding convex slides into the first guiding groove.

[0022] Optionally, the main shaft includes a sleeve, an inner shaft and a locking member. The inner shaft slides in the sleeve along the length direction of the sleeve, and the locking member is threadedly connected to the sleeve for pressing against the inner shaft; one end of the inner shaft extends out of the sleeve and installs the installation platform, and the shielding member and the support assembly are both arranged on the sleeve.

[0023] By adopting the above technical solution, the spindle adopts a telescopic structure of a sleeve and an inner shaft, and cooperates with a locking member to enable the height of the mounting platform to be adjustable. This design enables the bracket to adapt to measurement requirements of different heights.

[0024] In summary, the present application includes at least one of the following beneficial effects: 1. By adjusting the state of the support assembly, the bottom of the support leg can enter the accommodation cavity during storage, so as to isolate the dirt at the bottom of the support leg from the external environment, and thus it is not easy to cause secondary pollution during the process of transporting the bracket; 2. By selecting the rotation direction of the main hinge seat, it is possible to select whether the spiked end extends when the support leg is unfolded for use, improving the applicability of the bracket.

[0027] The following is further described in detail in conjunction with the attached Figure 1 to the attached Figure 9 This application.

[0028] An embodiment of this application discloses a laser rangefinder bracket. Refer to Figure 1 , the laser rangefinder bracket includes a main shaft 1, a mounting platform 2, a shielding member 3 and a support assembly 5. The main shaft 1 serves as a mounting base, the mounting platform 2 is mounted on the top end of the main shaft 1 for mounting a laser rangefinder. The shielding member 3 is fixedly mounted at the bottom end of the main shaft 1 for accommodating and shielding dirty parts, and the support assembly 5 moves on the main shaft 1 to realize the support of the bracket.

[0029] Refer to Figure 1 and Figure 2 , the main shaft 1 is in the shape of a round rod. The shielding member 3 includes a chassis 31 and an enclosure 32. The chassis 31 is fixed to the bottom surface of the main shaft 1. There are three enclosures 32, and all three enclosures 32 are fixed on the upper surface of the chassis 31, and the three enclosures 32 are evenly spaced along the circumferential direction of the main shaft 1. The chassis 31 is alternately provided with protruding portions 20 and concave portions 21 along the circumferential direction of the main shaft 1. The protruding portions 20 protrude radially from the main shaft 1 relative to the concave portions 21, and the protruding portions 20 correspond to the enclosures 32 one by one, so that the chassis 31 is in the shape of a clover. Each enclosure 32 and the protruding portion 20 together enclose an accommodating cavity 4 with an upward opening.

[0030] Refer to Figure 1 and Figure 3, the support assembly 5 includes a main hinge seat 51, a secondary hinge seat 52, a support leg 53, and a connecting rod 54. Both the main hinge seat 51 and the secondary hinge seat 52 are sleeved on the main shaft 1, and the secondary hinge seat 52 is located between the main hinge seat 51 and the chassis 31. One end of the support leg 53 is hinged to the bottom of the main hinge seat 51, and three support legs 53 are evenly spaced along the circumferential direction of the main shaft 1. The connecting rods 54 correspond to the support legs 53 one by one, and the connecting rods 54 are hinged between the support legs 53 and the secondary hinge seat 52.

[0031] Referring to Figure 2 , Figure 3 and Figure 4 , specifically, the main hinge seat 51 is annular, a guiding convex 9 is fixed on the inner wall of the main hinge seat 51, and first guiding grooves 10, second guiding grooves 11, and third guiding grooves 12 for the guiding convex 9 to slide are formed on the outer wall of the main shaft 1 to guide the movement of the main hinge seat 51 on the main shaft 1. Both the first guiding grooves 10 and the third guiding grooves 12 extend along the axial direction of the main shaft 1, the second guiding grooves 11 extend along the circumferential direction of the main shaft 1, and the second guiding grooves 11 communicate between the tops of the first guiding grooves 10 and the third guiding grooves 12. The central angle of the second guiding grooves 11 for the guiding convex 9 to slide is 60°.

[0032] The secondary hinge seat 52 is annular and has a counterweight. A limiting convex 6 is fixed on the inner wall of the secondary hinge seat 52, and a first limiting groove 7 and a second limiting groove 8 for the limiting convex 6 to slide are formed on the outer wall of the main shaft 1 to guide the movement of the secondary hinge seat 52 on the main shaft 1. The first limiting groove 7 extends along the axial direction of the main shaft 1 and is in the same straight line as the first guiding groove 10, and the extension length of the first limiting groove 7 is the same as the extension length of the first guiding groove 10. The second limiting groove 8 extends along the circumferential direction of the main shaft 1, the middle of the second limiting groove 8 communicates with the top of the first limiting groove 7, and the central angle of the second limiting groove 8 for the limiting convex 6 to slide is 120°.

[0033] Referring to Figure 3 , the top end of the support leg 53 is spherically hinged to the bottom end of the main hinge seat 51, and the two ends of the connecting rod 54 away from each other are respectively hinged to the secondary hinge seat 52 and the corresponding support leg 53 through a pin shaft. Through the movement of the main hinge seat 51 relative to the secondary hinge seat 52 in the axial direction of the main shaft 1 and the limiting effect of the connecting rod 54 on the support leg 53, the free end of the support leg 53 can rotate around its hinged end towards or away from the main shaft 1.

[0034] It should be noted that the support assembly 5 has corresponding use states, recovery states, and storage states to realize the use and storage of the bracket.

[0035] Referring to Figure 2 , Figure 4 and Figure 5, specifically, when the support assembly 5 is in use, the three feet 53 are all deployed away from the main shaft 1, the main hinge seat 51 is close to the secondary hinge seat 52, the guiding protrusion 9 abuts against the bottom end of the third guiding groove 12, and at the same time, the limiting protrusion 6 abuts against one end of the second limiting groove 8 away from the first limiting groove 7. To improve the stability of the main hinge seat 51, the main hinge seat 51 can be threadedly moved radially along itself with a threaded handle (not shown in the figure) that can abut against the outer wall of the main shaft 1, so as to relatively position the main hinge seat 51 and the main shaft 1.

[0036] Refer to Figure 2 , Figure 4 and Figure 6 , when the support assembly 5 is adjusted from the use state to the retracted state, the main hinge seat 51 moves upward relative to the secondary hinge seat 52 along the third guiding groove 12 until the guiding protrusion 9 is located at the junction of the third guiding groove 12 and the second guiding groove 11, the axis of the foot 53 is parallel to the axis of the main shaft 1, and the bottom of the foot 53 faces the recessed portion 21 of the chassis 31 and is higher than the top of the enclosure 32. Combining Figure 3 , and at the same time, the secondary hinge seat 52 maintains the state where the limiting protrusion 6 abuts against one end of the second limiting groove 8 away from the first limiting groove 7.

[0037] Refer to Figure 1 , Figure 2 and Figure 4 , when the support assembly 5 is adjusted from the retracted state to the storage state, the main hinge seat 51 first rotates around the main shaft 1 to move the guiding protrusion 9 to the junction of the second guiding groove 11 and the first guiding groove 10, and at the same time drives the secondary hinge seat 52 to rotate together, and the limiting protrusion 6 slides to the junction of the first limiting groove 7 and the second limiting groove 8. At this time, the bottom of the foot 53 faces the protruding portion 20 of the chassis 31 and is located above the enclosure 32. Then the main hinge seat 51 moves downward relative to the main shaft 1 to slide the guiding protrusion 9 to the bottom end of the first guiding groove 10, and at the same time drives the secondary hinge seat 52 to move downward by the gravity of the foot 53, the connecting rod 54 and the secondary hinge seat 52 itself, so that the limiting protrusion 6 slides into the bottom end of the first limiting groove 7. At this time, the bottom of the foot 53 extends into the accommodating cavity 4, and the bottom of the foot 53 is surrounded by the enclosure 32 and the protruding portion 20, so that the dirt at the bottom of the foot 53 is not easily dropped into the external environment.

[0038] Refer to Figure 6 and Figure 7, Further, the supporting leg 53 includes an outer sleeve rod 531 and an inner supporting rod 532. The outer sleeve rod 531 is in the shape of a round rod and has a hinged ball 22 at its top end. The outer sleeve rod 531 is ball-hinged to the bottom of the main hinge seat 51 through the hinged ball 22, and the top of the hinged ball 22 enters the main hinge seat 51. The inner supporting rod 532 is in the shape of a round rod with an outer diameter smaller than that of the outer sleeve rod 531. The bottom end of the inner supporting rod 532 is a spike end 13, and the spike head of the spike end 13 faces away from the main hinge seat 51. The inner supporting rod 532 axially and coaxially slides through the outer sleeve rod 531, and the top end of the inner supporting rod 532 passes through the hinged ball 22 and enters the main hinge seat 51.

[0039] At the same time, there is a reset elastic member 14 between the outer sleeve rod 531 and the inner supporting rod 532. The reset elastic member 14 includes a spring 141 and a moving convex 142. The moving convex 142 is fixed to the outer wall of the inner supporting rod 532. A moving groove 23 for the moving convex 142 to slide along its own axis is provided on the inner wall of the outer sleeve rod 531. The two ends of the spring 141 away from each other are respectively connected to the moving convex 142 and one end of the moving groove 23 close to the main hinge seat 51. The elastic force of the spring 141 gives the inner supporting rod 532 a tendency to move towards the main hinge seat 51, so that the spike end 13 is retracted into the outer sleeve rod 531.

[0040] Refer to Figure 3 and Figure 6 , The supporting assembly 5 further includes a base 55. The base 55 is in the shape of a circular ring and is coaxially sleeved on the main shaft 1. The inner wall of the base 55 has a travel convex 24. A travel groove 25 for the travel convex 24 to slide is provided on the outer circumference of the main shaft 1 along its own axis to limit the relative rotation of the base 55 with respect to the main shaft 1. At the same time, the main hinge seat 51 is rotatably connected to the bottom of the base 55.

[0041] Refer to Figure 7 and Figure 8 , There is a linkage assembly 15 between the base 55 and the main hinge seat 51 that cooperates with the inner supporting rod 532. Combining Figure 2 and Figure 4 , During the process of the guiding convex 9 sliding from one end of the second guiding groove 11 close to the first guiding groove 10 to one end of the second guiding groove 11 close to the third guiding groove 12, the linkage assembly 15 pushes the inner supporting rod 532 to move away from the base 55, so as to push the spike end 13 out of the outer sleeve rod 531. The spike end 13 extending out of the outer sleeve rod 531 can assist the supporting leg 53 to insert into the muddy or dirt road surface and improve the stability of the supporting leg 53. And when the supporting assembly 5 moves from one end of the second guiding groove 11 close to the third guiding groove 12 to one end of the second guiding groove 11 close to the first guiding groove 10, that is, during the process of the supporting assembly 5 moving from the retracted state to the stored state, the spike end 13 can be retracted back into the outer sleeve rod 531 under the action of the spring 141 to hide the dirt of the spike end 13.

[0042] Refer to Figure 8 andFigure 9 Specifically, the linkage assembly 15 includes an abutment sheet 151, an auxiliary column 152 and an abutment seat 153. The main hinge seat 51 has an operation chamber 26 connected to the hinge ball 22 and the inner support rod 532. The auxiliary column 152 corresponds to the inner support rod 532 one by one. The auxiliary column 152 is in the shape of a square column and is fixed in the operation chamber 26 of the main hinge seat 51. The length direction of the auxiliary column 152 is parallel to the axial direction of the main shaft 1. The abutment sheet 151 corresponds to the inner support rod 532 one by one. The abutment sheet 151 is in the shape of a circular arc sheet with an arc opening facing downward and is slidably sleeved on the auxiliary column 152 up and down. The top size of the auxiliary column 152 is enlarged to limit the abutment sheet 151 from escaping upward. The top of the inner support rod 532 abuts against the lower surface of the abutment sheet 151 under the drive of the spring 141. When the spike end 13 is received in the outer rod 531, the abutment sheet 151 is coaxial with the hinge axis at the top of the inner support rod 532.

[0043] The pressing seat 153 is fixed on the base 55 and extends into the operating cavity 26. The pressing seat 153 corresponds to the abutment sheet 151 one by one, and the side of the pressing seat 153 facing the corresponding abutment sheet 151 is a guide slope 16, which gradually slopes downward along the circumference of the base 55 away from the corresponding abutment sheet 151.

[0044] Reference Figure 2 , Figure 4 and Figure 8 When the guide protrusion 9 is located in the first guide groove 10, the pressing seat 153 and the corresponding contact piece 151 are in a separated state. When the main hinge seat 51 rotates to drive the guide protrusion 9 to move from the end of the second guide groove 11 close to the first guide groove 10 to the end of the second guide groove 11 close to the third guide groove 12, the contact piece 151 gradually contacts the guide bevel 16 and gradually moves downward under the guidance of the guide bevel 16 to press the spike end 13 of the inner support rod 532 downward out of the outer rod 531. It should be noted that when the main hinge seat 51 slides along the third guide groove 12 to drive the support leg 53 to rotate relative to the main hinge seat 51, the inner support rod 532 always contacts the contact piece 151, so that the spike end 13 can keep extending out of the outer rod 531.

[0045] Reference Figure 2 , Figure 4 and Figure 6 Furthermore, in order to enable the support leg 53 to be supported on the ground that needs to be protected from scratches, the bottom end of the outer rod 531 is arc-shaped and smooth, and the main shaft 1 is provided with a fourth guide groove 17 and a fifth guide groove 18 for the guide protrusion 9 to slide, so that when the support leg 53 is deployed and supported, the spiked end 13 is kept retracted in the outer rod 531.

[0046] Specifically, the fourth guide groove 17 communicates with the junction of the first guide groove 10 and the second guide groove 11. The fourth guide groove 17 extends circumferentially around the main shaft 1 in a direction away from the second guide groove 11, and the central angle of the extension of the fourth guide groove 17 is smaller than the central angle of the extension of the second guide groove 11. The fifth guide groove 18 communicates with one end of the fourth guide groove 17 away from the first guide groove 10. The fifth guide groove 18 extends axially along the main shaft 1 towards the bottom of the support leg 53, and the extension length of the fifth guide groove 18 is the same as the extension length of the third guide groove 12.

[0047] When the support assembly 5 is adjusted to the use state and there is no need to extend the spiked end 13, the adjustment path is that after the main hinge seat 51 drives the guiding protrusion 9 out of the first guide groove 10, the main hinge seat 51 rotates in a direction away from the second guide groove 11, so that the guiding protrusion 9 turns into the fourth guide groove 17. Then the main hinge seat 51 drives the guiding protrusion 9 to slide into the fifth guide groove 18, and the main hinge seat 51 drives the support leg 53 to unfold by moving relative to the main shaft 1 along the extension direction of the fifth guide groove 18. Among them, during the sliding process of the guiding protrusion 9 in the fourth guide groove 17, the pressing seat 153 never touches the adjacent abutting piece 151, so that the spiked end 13 remains in the part of the outer sleeve rod 531 for storage.

[0048] Refer to Figure 2 and Figure 4 Furthermore, the opening depth of the second guide groove 11 is the same as the opening depth of the fourth guide groove 17. The opening depth of the first guide groove 10 and the junction of the first guide groove 10 and the second guide groove 11 is greater than the opening depth of the second guide groove 11. A ball plunger 19 with a ball head embedded on the surface of the guiding protrusion 9 abuts against the surface of the guide groove. When the guiding protrusion 9 slides to face the first guide groove 10, the ball head of the ball plunger 19 abuts into the first guide groove 10 to indicate the state of the guiding protrusion 9 reaching the first guide groove 10. When the guiding protrusion 9 slides out of the first guide groove 10, the ball can be guided by its own arc surface and retracted into the guiding protrusion 9.

[0049] Refer to Figure 5 In addition, in order to improve the flexibility of the bracket, the main shaft 1 includes a sleeve 101, an inner shaft 102 and a locking member 103. The sleeve 101 is in a cylindrical shape, the inner shaft 102 is in a round shaft shape and slides coaxially in the sleeve 101, and the top end of the inner shaft 102 penetrates upward through the sleeve 101. The locking member 103 is a threaded handle that moves radially along the sleeve 101 in a threaded manner. The locking member 103 can abut against the outer wall of the inner shaft 102 to position the inner shaft 102 relative to the sleeve 101. The mounting platform 2 is installed at the top end of the inner shaft 102, and the laser rangefinder is installed on the mounting platform 2 through bolts. The shielding member 3 and the support assembly 5 are both installed on the sleeve 101.

[0050] Refer to Figure 1, moreover, a protruding moving handle 27 is fixed to the outer periphery of the main hinge seat 51 to assist in the movement of the hinge seat of the auxiliary column 152, and the moving handle 27 corresponds to the protruding part 20 one by one. When the bracket is placed flat in the storage state so that the outer periphery of the main hinge seat 51 and the outer peripheries of two adjacent protruding parts 20 are both in contact with the placement surface, the center of the main hinge seat 51 is higher than the center of the chassis 31, so that the accommodating cavity 4 is tilted upward toward the opening, so that the dirt in the accommodating cavity 4 is not easily dropped out.

[0051] The implementation principle of the laser rangefinder bracket according to the embodiment of the present application is as follows: when the bracket is used, the supporting feet 53 are unfolded outward by moving the main hinge seat 51, and the bottom of the supporting feet 53 is inserted into the corresponding accommodating cavity 4 when the bracket is stored. When it is necessary for the spiked end 13 to protrude when the bracket is in use, the moving path of the main hinge seat 51 driving the guiding convex 9 is the first guiding groove 10, the second guiding groove 11 to the third guiding groove 12. When it is not necessary for the spiked end 13 to protrude when the bracket is in use, the moving path of the main hinge seat 51 driving the guiding convex 9 is the first guiding groove 10, the fourth guiding groove 17 to the fifth guiding groove 18.

[0052] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
