Description

Technical Field

[0001] This utility model relates to the field of core geological logging technology, and in particular to an adjustable support for facilitating core box photography. Background Technology

[0002] A rock core is a cylindrical rock sample drilled from the ground using core drilling technology. When carrying out geological work such as core logging and sampling, macroscopic and microscopic photographs are taken of the rock core in the core box to effectively record geological phenomena and important information. In practice, geologists usually use handheld cameras or mobile phones to take pictures.

[0003] However, when taking photos using handheld cameras or mobile phones, problems such as shaky hands, uneven equipment, and dim lighting are inevitable, resulting in unclear, distorted, or tilted photos that cannot fully, truthfully, and effectively record and reflect geological phenomena. Furthermore, when using such images in reports, the tilted or distorted photos often lead to inconsistent cropping, affecting the quality of the report and the results. Therefore, we propose an adjustable support for taking photos of core boxes to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where traditional handheld devices are prone to shaky hands, uneven equipment, and poor lighting when photographing core boxes, resulting in unclear and skewed photos that fail to accurately record geological phenomena and affect report quality. Therefore, this invention proposes an adjustable support for facilitating core box photography.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable bracket for facilitating core box photography includes a base, a connecting block fixedly disposed on one side of the base, a support tube rotatably connected to the connecting block, an extension rod slidably disposed inside the support tube, a slider slidably disposed on the extension rod, a transverse fixing bracket rotatably connected to the slider, and a mobile phone holder for fixing the photography device detachably connected to the transverse fixing bracket. The support tube is provided with a locking assembly, which includes a fixed ring, a movable ring and a spring I. The fixed ring is fixedly sleeved on the support tube, the movable ring is slidably sleeved on the support tube and located below the fixed ring, the spring I is sleeved on the support tube and its two ends abut against the fixed ring and the movable ring respectively, a positioning pin is fixedly provided at the bottom of the movable ring, and a positioning hole adapted to the positioning pin is opened on the connecting block; A lighting component is provided at the bottom of the horizontal fixing bracket; The base is equipped with an expansion component for increasing the support area.

[0006] In one possible design, the locking assembly further includes a rubber sleeve fitted onto the support tube, with the spring I housed inside the rubber sleeve.

[0007] In one possible design, the transverse fixing bracket has a sliding cavity at one end near the slider, and a stop pin is slidably connected in the sliding cavity. The slider has a socket adapted to the stop pin on one side near the transverse fixing bracket. A spring II is provided in the sliding cavity, and the spring II provides elastic force to the stop pin to insert it into the socket.

[0008] In one possible design, two slide rods are fixedly installed inside the slide cavity, the stop pin is slidably sleeved on the slide rods, and the spring II is sleeved on the slide rods.

[0009] In one possible design, the support tube, the slider, and the transverse fixing bracket are all threaded with locking bolts for locking the extension rod, the slider, and the mobile phone mounting bracket.

[0010] In one possible design, the lighting assembly includes an LED light and a damping omnidirectional ball joint, the ball joint of which is connected to the LED light, and its base is connected to the lateral fixing bracket.

[0011] In one possible design, the extension component includes a storage compartment on one side of the base and a pull-out panel slidably disposed within the storage compartment, the pull-out panel being fixed to the base by a pin.

[0012] In one possible design, guide grooves are provided on the inner walls of both sides of the storage compartment, and guide wheels that roll in cooperation with the guide grooves are rotatably connected to both sides of the pull-out plate.

[0013] In one possible design, a bubble level is embedded in the top of the base, and both the top surfaces of the base and the pull-out plate are provided with scale lines.

[0014] In one possible design, the base has multiple casters with braking function mounted on its bottom.

[0015] In this application, firstly, when using the bracket, the bracket is moved to a suitable shooting position by using the universal wheels with brakes at the bottom of the base. The brake device of the universal wheels is then pressed to fix the bracket, enabling convenient movement and stable placement of the bracket. Next, depending on the placement requirements of the core box, if it is necessary to expand the support area of ​​the base, the pull-out plate can be pulled out so that the guide wheels on both sides roll in the guide grooves on the inner wall of the storage compartment. The pull-out plate is then pulled out of the storage compartment. The pull-out plate is slightly lifted so that the pin on the pull-out plate is aligned with the hole on the base and inserted. The magnets on the hole and the pin attract each other to fix the pull-out plate, expanding the support area and improving the stability of the bracket. Then, the core box is placed on the base and the pull-out plate, and the core box is accurately positioned according to the scale line on the top. Next, pull the support tube upwards to rotate it around the connecting block until it is upright. At this point, release the moving ring on the support tube. Under the elastic force of spring I, the moving ring will drive the bottom positioning pin to insert into the corresponding positioning hole at the top of the connecting block, thus fixing the support tube in an upright position. If it needs to be folded and stored later, pull the moving ring upwards to compress spring I, causing the positioning pin to disengage from the positioning hole. Rotate the support tube to a horizontal position, then release the moving ring to allow the positioning pin to insert into the positioning hole on one side of the connecting block. Next, bend the stop pin to retract it into the slide cavity. After rotating the horizontal fixed bracket to a horizontal position, loosen the stop pin. Under the elastic force of spring II, the stop pin inserts into the slot of the slider to fix the angle of the horizontal fixed bracket. Then, loosen the locking bolts on the support tube and the slider respectively to adjust the height of the extension rod and the position of the slider. After that, tighten the locking bolts on the support tube and the slider respectively. Finally, loosen the locking bolts on the horizontal fixed bracket, insert the phone holder into one end of the horizontal fixed bracket, and tighten the locking bolts on the fixed bracket to fix the phone holder. Finally, observe the bubble level on the base to confirm that the bracket is level and make adjustments. Then, place the core box according to the scale lines on the base or pull-out plate. If the ambient light is dim, the LED light angle can be adjusted by the damping universal ball to turn on the LED light for supplementary lighting, achieving the beneficial effect of flexible supplementary lighting and improving the clarity of the photos. After completing all adjustments, operate the photography equipment to take pictures of the core inside the core box.

[0016] Beneficial effects: In this utility model, the adjustable bracket for facilitating core box photography, through the adjustable support tube and extension rod structure, combined with the horizontal fixing bracket, can stably fix the shooting equipment and flexibly adjust its position, making the shooting process more stable and the obtained images clearer; In this utility model, the adjustable bracket that facilitates core box photography, through the base extension component and the pull-out plate with scale lines, not only meets the placement needs of core boxes of different sizes, but also provides a proportional reference during shooting, thereby enhancing the practicality of image data. In this utility model, the adjustable bracket that facilitates core box photography integrates lighting components and a convenient locking structure, which not only improves the lighting conditions for shooting, but also makes the operation and storage of the bracket more convenient, adapting to various environmental requirements of field work. In this invention, the adjustable support tube, extension rod, and horizontal fixing bracket can stably fix the shooting equipment and flexibly adjust its position, making shooting more stable and images clearer.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In one embodiment: Refer to Figure 1-5 A photo stand includes a base 1, a connecting block 2 fixedly disposed on one side of the base 1, a support tube 3 rotatably connected to the top of the connecting block 2, an extension rod 4 slidably disposed inside the support tube 3, a slider 5 slidably disposed through the extension rod 4, a horizontal fixing bracket 6 rotatably connected to one side of the slider 5 above the base 1, a mobile phone holder 8 inserted into one end of the horizontal fixing bracket 6, and a clamp on the mobile phone holder 8 for holding a mobile phone or other photography device for taking pictures. The support tube 3 is equipped with a locking assembly, which includes a movable ring 11 that is slidably sleeved on the support tube 3 and two positioning pins 12 that are symmetrically fixed at the bottom of the movable ring 11. The top and one side of the connecting block 2 are provided with positioning holes 201 corresponding to the two positioning pins 12. When the support tube 3 is used upright, the two positioning pins 12 are inserted into the corresponding positioning holes 201 on the top of the connecting block 2. When the support tube 3 is folded and stored, the two positioning pins 12 are inserted into the corresponding positioning holes 201 on the side of the connecting block 2. Through this locking assembly design, the switching between the upright and folded states of the support tube 3 can be quickly realized, making the operation and storage of the bracket more convenient and adaptable to various outdoor working environments.

[0021] The locking assembly also includes a fixing ring 10 fixedly sleeved on the support tube 3, with the fixing ring 10 positioned above the moving ring 11. A spring I 13 is sleeved on the support tube 3 between the fixing ring 10 and the moving ring 11. The top and bottom ends of the spring I 13 abut against the bottom of the fixing ring 10 and the top of the moving ring 11, respectively. Pulling the moving ring 11 upwards compresses the spring I 13. After releasing the moving ring 11, the spring I 13's elastic force causes the moving ring 11 to automatically insert the positioning pin 12 into the positioning hole 201, eliminating the need for manual alignment and improving operational convenience. A rubber sleeve 14 is sleeved on the support tube 3 between the fixing ring 10 and the moving ring 11, with the spring I 13 located inside the rubber sleeve 14. The rubber sleeve 14 protects the spring I 13, preventing dust and impurities from adhering to its surface during fieldwork, thus extending its service life.

[0022] A sliding cavity is provided at one end of the transverse fixed bracket 6 near the slider 5. A stop pin 16 is slidably connected inside the sliding cavity. An insertion port 501 is provided on the side of the slider 5 near the transverse fixed bracket 6. One end of the stop pin 16 extends to the outside of the transverse fixed bracket 6 and is inserted into the insertion port 501. Two sliding rods 17 are fixedly connected to one side of the inner wall of the sliding cavity. Both sliding rods 17 slide through the stop pin 16. Springs II 18 are sleeved on both sliding rods 17. The two ends of the two springs II 18 abut against one side of the stop pin 16 and one side of the inner wall of the sliding cavity, respectively. A clearance opening is provided at the top of the transverse fixed bracket 6. The top end of the stop pin 16 passes through the clearance opening and extends to the top of the transverse fixed bracket 6. By bending the top of the stop pin 16, the stop pin 16 will slide along the slide bar 17 and compress the spring II 18. At this time, the horizontal fixing bracket 6 can be rotated so that it can be folded and stored or unfolded horizontally. After releasing the stop pin 16, under the elastic force of the spring II 18, the stop pin 16 can automatically insert into the socket 501 to fix the horizontal fixing bracket 6, so that the horizontal fixing bracket 6 can be fixed after being unfolded horizontally. With the help of the sliding extension rod 4 and the slider 5, the position of the camera can be flexibly adjusted to make the shooting process more stable.

[0023] Locking bolts 7 are threaded through the support tube 3, slider 5, and horizontal fixing bracket 6 to lock the corresponding extension rod 4, slider 5, and phone holder 8. Loosening the locking bolts 7 on the support tube 3 allows the extension rod 4 to slide and adjust its height within the support tube 3; tightening them secures the extension rod 4. Loosening the locking bolts 7 on the slider 5 allows the slider 5 to move and adjust its lateral position on the extension rod 4; tightening them secures the slider 5. Loosening the locking bolts 7 on the horizontal fixing bracket 6 allows the insertion position of the phone holder 8 to be adjusted; tightening them secures the phone holder 8. This design of locking bolts 7 ensures that the camera remains stable after the position and angle are adjusted, preventing shaking during shooting and resulting in clearer images.

[0024] A lighting assembly is installed at the bottom of the horizontal fixing bracket 6. The lighting assembly includes an LED light 9 installed at the bottom of the horizontal fixing bracket 6 and a damping universal ball joint 15 fixedly installed at the bottom of the horizontal fixing bracket 6. The ball joint of the damping universal ball joint 15 is fixedly connected to a mounting base, and the horizontal fixing bracket 6 is fixedly connected to the mounting base. The LED light 9 can provide supplementary lighting in low-light environments, improving the lighting conditions for shooting. The damping universal ball joint 15 can flexibly adjust the illumination angle of the LED light 9, and can precisely adjust the light direction according to the shooting needs of the core box, further improving the clarity of the image and ensuring that the geological information of the core is fully presented.

[0025] The base 1 is provided with an expansion component for expanding the support area of ​​the base 1. The expansion component includes a storage compartment 101 on one side of the base 1 and a pull-out plate 20 disposed in the storage compartment 101. It also includes guide grooves 102 on the inner walls of both sides of the storage compartment 101. Guide wheels 19 are rolled in both guide grooves 102. The two guide wheels 19 are rotatably connected to the two sides of the pull-out plate 20 respectively. Multiple pins 21 are fixedly connected to one side of the pull-out plate 20. The base 1 has a hole corresponding to the pins 21 on one side. When the pull-out plate 20 is used, the pull-out plate 20 is pulled out and slightly lifted so that the multiple pins 21 are aligned with the corresponding holes and inserted. Magnets that attract each other are provided on the inner walls of the multiple holes and on the pins 21. The guide wheel 19 reduces friction between the pull-out plate 20 and the storage compartment 101, making the pull-out plate 20 easier to pull out and push in. The pulled-out plate 20 expands the support area of ​​the base 1, adapting to the placement needs of core boxes of different sizes. The pin 21 and the magnet in the socket attract each other, which can stably fix the pull-out plate 20, preventing the pull-out plate 20 from sliding during use and improving the overall stability of the bracket.

[0026] This application can be used in the field of core geological logging technology, or in other fields applicable to this application.

[0027] In another embodiment: Reference Figure 1-5 Based on Embodiment 1, an adjustable support for facilitating core box photography is proposed. Applied to the field of core geological logging technology, both the base 1 and the pull-out plate 20 have scale lines 22 on their tops. When the core box is placed on the base 1 and pull-out plate 20, the scale lines 22 provide a proportional reference, allowing operators to accurately position the core box and ensuring accurate positioning during photography. This enhances the practicality of the image data and makes the dimensional relationships of the core more clearly apparent when citing photos in subsequent reports. A bubble level 23 is fixedly embedded in the top of the base 1. Observing the bubble level 23 allows the operator to determine whether the support is level. The operator can adjust the support according to the display of the bubble level 23 to ensure that the photographing equipment and the core box are level, avoiding tilted or distorted photos and ensuring the quality of reports and results. The base 1 is fixedly equipped with multiple casters 24 with brakes at the bottom. The casters 24 can be used to easily move the bracket to a suitable shooting position. After moving to the target position, stepping on the brake device can fix the bracket, realizing the function of convenient movement and stable placement of the bracket, which is especially suitable for the needs of frequently changing shooting locations when working in the field.

[0028] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
