Description

Technical Field

[0001] This invention relates to the field of photographic slide rail technology, specifically to a spliced ​​photographic slide rail with angle adjustment features. Background Technology

[0002] Camera sliders are commonly used in photography to allow the camera to pan within a certain range. When the camera moves, if the subject remains stationary, the camera's angle needs to be constantly rotated and adjusted to ensure the subject stays within the frame. However, since the camera angle is manually adjusted, it's difficult to guarantee the subject remains in the same position within the composition. Therefore, curved camera sliders have become available on the market. These sliders allow for close-up shooting at 1.5m-2.5m, simulating the human eye's actual close-up perspective and reproducing a sense of realism and intimacy without distortion.

[0003] However, existing curved camera sliders are all fixed curves and can only bend to one side. The overall curvature of the slider cannot be adjusted, thus failing to achieve diverse shooting options and cannot be adjusted according to the geographical conditions of the shooting location. Shooting is limited by geographical conditions, and the overall design has certain limitations in practical use. Summary of the Invention

[0004] The purpose of this invention is to provide a spliced ​​photographic slide rail with angle adjustment, in order to solve the problems mentioned in the background art, that existing curved photographic slide rails are all fixed curves and can only bend to one side, and the overall curvature of the slide rail cannot be adjusted, thus failing to achieve diversified shooting, unable to be adjusted according to the geographical conditions of the shooting location, and the shooting is limited by geographical conditions, and the overall use has certain limitations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a splicing photographic slide rail with angle adjustment, comprising a flexible guide rail, a photographic carriage base, a fixing block, a mounting base, and an elastic abutment frame. Positioning seats are evenly spaced on the bottom outer surface of the flexible guide rail. A fixing block is fixedly mounted on one side of the bottom of each positioning seat. A positioning post is fixedly installed at the middle position of the top outer surface of each positioning seat. A connecting plate is fixedly mounted through one side of each positioning post, and the other end of the connecting plate is rotatably mounted through one side of the positioning post at the top of another positioning seat. An elastic abutment frame is provided on one side of the top of each positioning post. Positioning holes are evenly spaced and embedded around the top outer surface of each positioning seat. The photographic carriage base is slidably engaged on one side of the top of the flexible guide rail.

[0006] Preferably, an auxiliary groove is embedded on one side of the outer surface of the positioning seat, and the auxiliary groove is arc-shaped, and the inner wall of one side of the auxiliary groove abuts and fits against the outer surface of one side of the positioning seat on the other side.

[0007] By adopting the above technical solution, when the positioning seat on one side rotates around the positioning seat on the other side during use, the overall contact area is larger, resulting in higher overall rotational and contact stability.

[0008] Preferably, the connecting plate has through holes on the side of the positioning hole at the top of the positioning seat near its rotating end. A contact rod is slidably disposed longitudinally through each through hole. The bottom end of the contact rod is installed against the inside of one of the positioning holes to restrict the rotation of the connecting plate.

[0009] By adopting the above technical solution, the entire unit can be used in a way that allows the abutment rod to contact the positioning hole at the top of the positioning seat, thereby preventing the two positioning seats from being rotated and adjusted, thus ensuring the stability of the entire unit after adjustment.

[0010] Preferably, an auxiliary handle is fixedly installed on the outer surface of the top end of the abutting rod, a limit rod is slidably installed through one side of the auxiliary handle, the bottom end of the limit rod is fixedly installed on the outer side of the top end of the connecting plate, a limit block is fixedly installed on the top end of the limit rod, and a return spring is sleeved through the outer surface of the limit rod between the limit block and the connecting plate.

[0011] By adopting the above technical solution, the auxiliary handle on one side can be pulled during use to disengage the bottom contact rod from the positioning hole, making the overall operation convenient.

[0012] Preferably, the two ends of the return spring are respectively embedded and installed on the outer side of the bottom end of the limiting block and the outer side of the top end of the connecting plate. The function of the return spring is to cause the auxiliary handle and the abutment rod to abut and descend simultaneously when the auxiliary handle loses its lifting force. The top outer surface of the positioning column is provided with a mounting seat.

[0013] By adopting the above technical solution, the whole unit can automatically reset during use through the setting of the reset spring, thus ensuring the stability of the abutment rod inserted into the positioning hole.

[0014] Preferably, the flexible guide rail is provided with a limiting mounting groove embedded around the inside of the side near the mounting base. The elastic abutment is sleeved and installed on the outer surface of the limiting mounting groove. The bottom end of the elastic abutment is provided with a positioning bolt, and the bottom end of the positioning bolt is installed on the outside of the top end of the mounting base to restrict the flexible guide rail.

[0015] By adopting the above technical solution, the flexible guide rail can be positioned by the elastic contact frame to ensure the integrity of the whole. When the positioning seat rotates, it drives the flexible guide rail at the top to bend and adjust at the same time, thereby adjusting the bending angle of the whole.

[0016] Preferably, the thickness of the limiting mounting groove is the same as the wall thickness of the elastic abutment frame, so that the surface of the flexible guide rail is flat.

[0017] The above technical solution ensures that the camera carriage base moves more smoothly on the surface of the flexible guide rail during use, and will not get stuck.

[0018] Preferably, a fixing ring is fixedly installed on the inner wall of the rotating end of the connecting plate, and an installation cavity is embedded in the inner wall of the fixing ring at equal intervals. A limit slider is installed inside the side of the installation cavity near the positioning column. Limit grooves are embedded in the inner walls of the two sides of the installation cavity near the limit slider. Both ends of the limit slider are slidably engaged in the limit groove on one side to limit the movement direction of the limit slider.

[0019] The above technical solution ensures that the limit slider is more stable during use, thus guaranteeing the overall performance.

[0020] Preferably, a compression spring is fixedly installed between one outer surface of the limiting slider and one inner wall of the mounting cavity. A fixing seat is fixedly installed on the outer surface of the limiting slider away from the compression spring. A ball is rotatably installed inside the fixing seat on the side away from the limiting slider. An arc-shaped groove is embedded on the outer surface of the positioning post near the ball. One side of the ball is engaged with the corresponding arc-shaped groove.

[0021] The above technical solution allows the ball bearings to contact the inside of the arc groove when not rotating, thanks to the resistance of the compression spring. When rotating, the compression spring compresses, causing the ball bearings to disengage from the inside of the arc groove. This also gives the whole unit a certain jerky feel when rotating, making overall rotation positioning more convenient and overall stability higher.

[0022] Compared with the prior art, the beneficial effects of the present invention are: it is equipped with an angle-adjustable splicing photographic slide rail.

[0023] 1. When in use, this photography slide rail is assembled with multiple positioning seats and connecting plates, and a flexible guide rail supported by a flexible rubber material at the top. This allows the overall curvature and curve of the slide rail to be adjusted arbitrarily, making it adaptable to different venues and photography needs. This broadens its applicability, expands its use beyond a single purpose, and improves its overall performance.

[0024] 2. When in use, this camera slide rail features equally spaced embedded positioning holes on the top surface of the positioning seat. Combined with a side limit rod, a stop rod, a through hole, an auxiliary handle, and a return spring, this design ensures the stability of the overall angle adjustment after the positioning seat is rotated. This guarantees the overall positioning effect, preventing changes after adjustment. Adjustment is also more convenient; simply raise the stop rod to disengage for rotation or lower it for positioning. Overall, it offers excellent performance.

[0025] 3. When the camera slide rail is in use, elastic abutment brackets are fixedly installed at equal intervals on the outer surface of the flexible guide rail. This allows the bottom positioning seat to rotate, causing the top flexible guide rail to rotate simultaneously. This adjusts the curvature of the flexible guide rail and ensures overall stability. At the same time, the embedded setting of the limiting installation groove ensures that the elastic abutment brackets do not protrude after installation, ensuring the flatness of the flexible guide rail surface. This results in better overall performance, smoother operation, and less likelihood of jamming.

[0026] 4. When the camera slide rail is in use, an arc-shaped auxiliary groove is embedded on one side of the positioning seat. This makes the overall fit between the positioning seats on one side and the positioning seats on the other side better, increases the contact area, and ensures the stability of the overall adjustment while rotating, resulting in a better overall performance.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-8This invention provides a technical solution: a splicing photographic slide rail with angle adjustment, comprising a flexible guide rail 1, a photographic carriage base 2, a positioning seat 3, a fixing block 4, an auxiliary groove 5, a positioning post 6, a connecting plate 7, a positioning hole 8, a limiting rod 9, an abutment rod 10, a through hole 11, an auxiliary handle 12, a return spring 13, a limiting block 14, a mounting seat 15, a limiting mounting groove 16, an elastic abutment frame 17, a positioning bolt 18, a fixing ring 19, a mounting cavity 20, a limiting slide groove 21, a limiting slider 22, a fixing seat 23, a ball bearing 24, an arc groove 25, and a compression spring 26. Positioning seats 3 are evenly spaced on the bottom outer surface of the guide rail 1. A fixing block 4 is fixedly installed on one side of the bottom of each positioning seat 3. A positioning post 6 is fixedly installed in the middle of the top outer surface of each positioning seat 3. A connecting plate 7 is fixedly installed through one side of each positioning post 6. The other end of the connecting plate 7 is rotatably installed through one side of the positioning post 6 at the top of another positioning seat 3. An elastic abutment bracket 17 is provided on one side of the top of the positioning post 6. Positioning holes 8 are evenly spaced and embedded around the top outer surface of the positioning seat 3. A camera carriage base 2 is slidably engaged on one side of the top of the flexible guide rail 1.

[0038] Each of the outer surfaces of one side of the positioning seat 3 is provided with an auxiliary groove 5, which is arc-shaped. The inner wall of one side of the auxiliary groove 5 is in contact with the outer surface of the other side of the positioning seat 3. By embedding the arc-shaped auxiliary groove 5 on one side of the positioning seat 3, the contact effect between the two positioning seats 3 is better when they are in contact with and rotated to adjust, increasing the contact area. This ensures the stability of the overall contact adjustment while rotating, resulting in a better overall performance.

[0039] On the side of the positioning seat 3 near the rotating end of the connecting plate 7, there are through holes 11 extending through one side of the positioning hole 8. Abutment rods 10 are slidably mounted longitudinally through each through hole 11. The bottom end of each abutment rod 10 is installed against the interior of one of the positioning holes 8 to restrict the rotation of the connecting plate 7. An auxiliary handle 12 is fixedly installed on the outer surface of the top of the abutment rod 10. A limit rod 9 is slidably mounted through one side of the auxiliary handle 12. The bottom end of the limit rod 9 is fixedly installed on the top of the connecting plate 7. On one side of the outside, a limit block 14 is fixedly installed at the top of the limit rod 9, and a return spring 13 is sleeved through the outer surface of the limit rod 9 between the limit block 14 and the connecting plate 7; the two ends of the return spring 13 are respectively embedded in the outer side of the bottom end of the limit block 14 and the outer side of the top end of the connecting plate 7. The function of the return spring 13 is that when the auxiliary handle 12 loses its lifting force, it will simultaneously push the auxiliary handle 12 and the abutment rod 10 to abut and descend. A mounting seat 15 is installed on the outer surface of the top end of the positioning column 6.

[0040] When using this camera slider as a whole, it combines... Figure 2 and Figure 3 As shown, when the overall curvature needs to be adjusted, firstly, the auxiliary handle 12 on one side is lifted and pulled. By pulling the auxiliary handle 12, the abutment rod 10 on one side is disengaged from the positioning hole 8 on the top side of the positioning seat 3, so that the two positioning seats 3 can rotate freely. Then, by the limiting sleeve of the connecting plate 7, the two positioning seats 3 can rotate, and the overall curvature is changed. The overall adjustment is convenient and effective.

[0041] After the overall adjustment is completed, the auxiliary handle 12 is loosened. With the loosening of the auxiliary handle 12, the elastic rebound of the return spring 13 will press the auxiliary handle 12 at the bottom and the abutment rod 10 on one side into the positioning hole 8 to engage. This will allow the two positioning seats 3 to rotate and be positioned, ensuring the stability of the overall curvature adjustment.

[0042] Following the steps described above, the subsequent positioning seats 3 can be rotated and adjusted as needed to change the overall curvature, such as... Figure 8 As shown, the curvature of the slide rail can be adjusted during use, thus enabling diverse shooting methods. It can be adjusted according to the geographical conditions of the shooting location, and is not limited by geographical conditions. After the overall adjustment is completed, the slide rail can be positioned and installed on the ground by the fixing blocks 4 on both sides of the bottom of the positioning base 3 to ensure the overall stability of use. Then, the photography equipment can be installed on the electrically driven photography carriage base 2, so that the photography carriage base 2 can drive the photography equipment to move stably on the surface of the flexible guide rail 1 for shooting. The overall use effect is good, the operation is simple and convenient, and the overall application range is wide.

[0043] The flexible guide rail 1 has a limiting mounting groove 16 embedded around the side of the mounting base 15. The elastic abutment frame 17 is sleeved on the outer surface of the limiting mounting groove 16, and a positioning bolt 18 is installed through the bottom side of the elastic abutment frame 17. The bottom ends of the positioning bolts 18 are installed on the outside of the top side of the mounting base 15 to restrict the flexible guide rail 1. The thickness of the limiting mounting groove 16 is the same as the wall thickness of the elastic abutment frame 17 to make the surface of the flexible guide rail 1 flat.

[0044] When using the whole, combine Figure 2 and Figure 4As shown, when the positioning seat 3 rotates to a certain angle, the flexible guide rail 1 at the top rotates due to the fixed installation of the elastic contact frame 17, thereby adjusting the overall curvature. The overall installation is highly stable. At the same time, when in use, the thickness of the limiting installation groove 16 is the same as the wall thickness of the elastic contact frame 17, so that the elastic contact frame 17 will not protrude after being installed, ensuring the flatness of the surface of the flexible guide rail 1. The overall performance is better, the overall operation is smoother, and it is not easy to jam, ensuring the overall operation and use effect.

[0045] A fixing ring 19 is fixedly installed on the inner wall of the rotating end of the connecting plate 7. The inner wall of the fixing ring 19 is embedded with an installation cavity 20 at equal intervals. A limit slider 22 is installed inside the side of the installation cavity 20 near the positioning post 6. A limit groove 21 is embedded on the inner wall of the two sides of the installation cavity 20 near the limit slider 22. Both ends of the limit slider 22 are slidably engaged in the limit groove 21 on one side to limit the movement direction of the limit slider 22. A compression spring 26 is fixedly installed between the outer surface of one side of the limit slider 22 and the inner wall of one side of the installation cavity 20. A fixing seat 23 is fixedly installed on the outer surface of the limit slider 22 away from the compression spring 26. A ball bearing 24 is rotatably installed inside the fixing seat 23 away from the limit slider 22. An arc groove 25 is embedded on the outer surface of the positioning post 6 near the ball bearing 24. One side of the ball bearing 24 is engaged in the arc groove 25 on the corresponding side.

[0046] When using the whole, combine Figure 6 and Figure 7 As shown, when the overall curvature is adjusted, the connecting plate 7 rotates outside the positioning post 6 at the top of the other positioning plate 3 via the positioning seat 3. Due to the rotation of the connecting plate 7, the ball 24 is pressed against one side of the arc groove 25, causing the limiting slider 22 on one side of the ball 24 to move inward, compressing the compression spring 26 on one side. Through the compression of the compression spring 26, the ball 24 is disengaged from the arc groove 25 on one side, causing the whole to rotate. When it rotates to a certain position, the ball 24 is aligned with the arc groove 25 on the other side. At this time, the spring 26 rebounds, pushing the limiting slider 22 outward, causing the ball 24 on one side to abut into the arc groove 25. According to the above working process, when the overall curvature is adjusted, the overall rotation has a certain sense of hesitation, which makes the positioning effect after the overall rotation better. It is not easy for the whole to be driven back to its original position by the rebound force formed by the twisted flexible guide rail 1, which facilitates the alignment and insertion of the abutment rod 10 and ensures the overall stability.

[0047] Working Principle: When using this spliced ​​photographic slide rail with angle adjustment, the entire slide rail is used in conjunction with multiple positioning seats 3 and connecting plates 7, and the flexible guide rail 1 supported by the flexible rubber material at the top. This allows for arbitrary rotation and adjustment of the overall curvature and curve of the slide rail, making it adaptable to different sites and photographic needs. This broadens its applicability and expands its use beyond a single application, resulting in better overall performance and increased practicality. Standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
