Description

Technical Field

[0001] The present application relates to the field of brackets, and in particular to an auxiliary bracket for photographing cultural relics. Background Art

[0002] After the cultural relics are retrieved, they are usually photographed in all directions to preserve the image data. Among them, when photographing some cultural relics such as ceramics or pottery jars, auxiliary brackets are usually used for shooting. These auxiliary brackets generally include a turntable that can rotate 360 degrees. Taking pottery jars as an example, when photographing, in order to be able to capture the image of the pottery jar in all directions, the pottery jar is generally placed in two positions: The first method is to place the pottery jar directly on the turntable with the bottom facing down and let the turntable drive it to rotate in a circular motion, so as to capture a full-scale image of the circumference of the pottery jar. In this method, since the bottom of the pottery jar is on the turntable, the bottom of the pottery jar cannot be photographed, so it is necessary to further switch to the second method to place the pottery jar and continue shooting.

[0003] The second method is to place the cultural relics upside down on the turntable, that is, the mouth of the jar falls on the turntable. At this time, the bottom of the jar is facing upwards, so it can be photographed completely.

[0004] However, in actual work, the mouths of some pottery jars may be irregular or defective, so that in the second method mentioned above, the mouths of the pottery jars cannot be stably seated on the turntable, and thus there is room for improvement. Summary of the Invention

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of this application is to provide an auxiliary bracket for photographing cultural relics.

[0006] To achieve the above objectives, this application provides the following technical solutions.

[0007] An auxiliary bracket for photographing cultural relics, comprising: A base, wherein the base is provided with a turntable capable of rotating circumferentially relative to the base about a first axis; the first axis extends vertically; A support rod is provided on the turntable and extends vertically. In the circumferential direction, the support rod rotates coaxially with the turntable. In the vertical direction, the support rod is movable between a first position and a second position relative to the turntable. In the first position, the support rod does not extend beyond the top surface of the turntable. In the second position, the support rod at least partially protrudes from the top surface of the turntable for supporting the cultural relic. The locking component is used to lock the support rod in the second position; the locking component can be unlocked.

[0008] As an optional embodiment of the present application, a guide structure is provided between the support rod and the turntable. Under the action of the guide structure, the support rod and the turntable maintain relative positioning in the circumferential direction and can move relative to each other in the vertical direction.

[0009] As an optional embodiment of the present application, the guide mechanism includes a convex key and a keyway both extending vertically, the convex key is embedded in the keyway and can move vertically along the keyway; one of the convex key and keyway is provided on the turntable, and the other is provided on the support rod.

[0010] As an optional embodiment of the present application, the turntable includes a rotating shaft extending vertically; the rotating shaft is rotatably connected to the base, the central axis of the rotating shaft constitutes a first axis, and the rotating shaft at least partially extends from the bottom of the base to form an extension section; the support rod is vertically arranged in the rotating shaft.

[0011] As an optional embodiment of the present application, the locking component includes a bolt, which is threadedly connected to the extension section, and the inner end of the bolt is pressed against the support rod to lock the support rod.

[0012] As an optional embodiment of the present application, the bracket further includes a driving mechanism for driving the turntable to rotate.

[0013] As an optional embodiment of the present application, the driving mechanism includes a motor, and the motor and the extension section of the rotating shaft are driven by a belt or a gear.

[0014] As an optional embodiment of the present application, a supporting portion is provided on the top of the support rod, and a receiving groove capable of accommodating the supporting portion is provided on the top surface of the turntable at a position corresponding to the supporting portion.

[0015] As an optional embodiment of the present application, the supporting portion includes a substrate and a flexible component provided on the top of the substrate.

[0016] As an optional embodiment of the present application, the flexible component includes a rubber pad or an airbag.

[0017] Compared with the prior art, this application has the following beneficial effects: The present application provides a support rod on the turntable that is relatively positioned with the turntable in the circumferential direction and can be relatively movable in the vertical direction, so that the support can be placed in two different ways on the cultural relics, thereby achieving all-round photography of the cultural relics. Taking the pottery jar as an example, the two different placement methods are: The first one is that the support rod is retracted to the first position, and the pottery pot is placed directly on the turntable with its bottom facing downward. At this time, it is equivalent to directly supporting the pottery pot by relying on the turntable. When shooting, the pottery pot is driven to rotate circumferentially by the turntable, so that the surrounding wall of the pottery pot can be photographed.

[0018] The second method is to extend the support rod to the second position and lock it, then turn the pot upside down on the support rod, that is, the support rod is directly inserted into the pottery pot, and the inner bottom wall of the pottery pot is supported from the inside of the pottery pot. At this time, the bottom of the pottery pot is facing upward to photograph the bottom area of the pottery pot.

[0019] It can be seen that in the second method, it is not necessary to place the mouth of the pottery jar on the turntable, so even if the mouth of the jar is damaged or irregular, it will not affect the placement of the pottery jar.

[0024] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0025] Reference Figure 1-6 As shown, this embodiment provides an auxiliary bracket for photographing cultural relics, which is mainly suitable for photographing cultural relics such as ceramic bottles or pottery jars. In order to facilitate understanding of this embodiment, the following embodiment is specifically described using the pottery jar as an example, where the pottery jar is shown in part M in the accompanying drawings.

[0026] The bracket provided in this embodiment mainly includes a base 1, a support rod 3 and a locking component, and each component is described separately below.

[0027] like Figure 1 As shown, a plurality of legs 11 for supporting the base 1 are provided at the bottom of the base 1 , and the base 1 is raised to a certain height relative to the ground by the legs 11 .

[0028] A turntable 2 is provided on the base 1 and can rotate circumferentially relative to the base 1 around a first axis. The turntable 2 is a circular disc structure, and its top surface is a plane serving as a carrying surface for supporting the pottery jar, wherein the first axis extends vertically, or in other words, the first axis is arranged vertically.

[0029] In some embodiments, the specific rotational installation method of the turntable 2 relative to the base 1 is as follows: Figure 6 As shown, the turntable 2 includes a rotating shaft 22 extending vertically, wherein the rotating shaft 22 and the turntable 2 can be an integrally formed structure, or can be fixed to the turntable 2 in a fixed connection manner.

[0030] In addition, the rotating shaft 22 is connected to the base 1 through a bearing so as to rotate around the first axis, wherein the center axis of the rotating shaft 22 constitutes the first axis, so that the turntable 2 can rotate relative to the base 1 around the first axis with the rotating shaft 22 as the rotation center.

[0031] The turntable 2 can be rotated manually or electrically. For example, this embodiment further includes a driving mechanism 4 for driving the turntable 2 to rotate. Specifically: like Figure 3As shown, the driving mechanism 4 includes a motor 41, and the rotating shaft 22 at least partially extends from the bottom of the base 1 to form an extension section; the motor 41 and the extension section of the rotating shaft 22 are driven by a belt drive or gear drive mechanism 4. Taking belt drive as an example, the motor 41 is fixed on the base 1, and a driving pulley 42 is provided on the main shaft of the motor 41, and a driven pulley 43 is provided on the extension section. A transmission belt 44 is sleeved between the driving pulley 42 and the driven pulley 43. When working, the motor 41 drives the rotating shaft 22 to rotate through the transmission belt 44, and then drives the turntable 2 to rotate.

[0032] The support rod 3 is mainly used to be inserted into the pottery pot to support the pottery pot vertically. The support rod 3 is provided on the turntable 2 and extends vertically. In the circumferential direction, the support rod 3 and the turntable 2 rotate coaxially, that is, the support rod 3 can rotate synchronously with the turntable 2 around the first axis; In the vertical direction, the support rod 3 can move between a first position and a second position relative to the turntable 2: In the first position, Figure 1 As shown, the support rod 3 does not exceed the top surface of the turntable 2, so as to prevent the support rod 3 from protruding from the top surface of the turntable 2 and hindering the bottom of the pottery pot from being placed stably on the turntable 2.

[0033] In the second position, Figure 2 As shown, the support rod 3 at least partially protrudes from the top surface of the turntable 2 to support the artifact; the support rod 3 is vertically inserted into the rotating shaft 22. A locking member is used to lock the support rod 3 in the second position; the locking member can be unlocked. It is worth noting that the second position here is not a fixed position; it is determined by the specific height of the pottery jar being photographed. In short, as long as the support rod 3 is extended to a height that can lift the pottery jar, it is considered to be in the second position.

[0034] In actual use, the pottery jar can be placed in two different ways: The first one, such as Figure 4 As shown, the support rod 3 is retracted to the first position, and the pottery pot is directly placed on the turntable 2 with its bottom facing downward. At this time, it is equivalent to directly supporting the pottery pot by relying on the turntable 2. When shooting, the pottery pot is driven to rotate circumferentially by the turntable 2, so that the peripheral wall of the pottery pot can be photographed.

[0035] The second type, such as Figure 5 As shown, the support rod 3 is extended to the second position and locked, and then the pot is turned upside down on the support rod 3, that is, the support rod 3 is directly inserted into the pot, and the inner bottom wall of the pot is supported from the inside of the pot. At this time, the bottom of the pot is facing upward to photograph the bottom area of the pot.

[0036] It can be seen that in the second method, it is not necessary to place the mouth of the pottery pot on the turntable 2, so even if the mouth of the pot is damaged or irregular, it will not affect the placement of the pottery pot.

[0037] In order to keep the support rod 3 and the turntable 2 relatively positioned in the circumferential direction and relatively movable in the vertical direction, in some embodiments, such as Figure 6 As shown, the support rod 3 is vertically inserted into the rotating shaft 22, and a guide structure is provided between the support rod 3 and the rotating disk 2. Figure 2 As shown, the guide mechanism includes a convex key 31 and a key slot 221 both extending vertically, the convex key 31 is embedded in the key slot 221 and can move vertically along the key slot 221; one of the convex key 31 and the key slot 221 is provided on the turntable 2, and the other is provided on the support rod 3.

[0038] For example, as specifically shown in this embodiment, the key groove 221 is arranged on the outer peripheral wall of the support rod 3, and the key groove 221 is arranged in the rotating shaft 22. With the cooperation of the key groove 221 and the convex key 31, the support rod 3 and the turntable 2 maintain relative positioning in the circumferential direction and can move relative to each other in the vertical direction.

[0039] The reason why the support rod 3 and the turntable 2 are kept relatively positioned in the circumferential direction is that the turntable 2 can drive the support rod 3 to rotate together when it rotates. In this way, even if the pottery pot is placed in the second way mentioned above, the pottery pot can still be rotated, so that the pottery pot can be photographed in a rotating form.

[0040] like Figure 6 As shown, the locking component includes a bolt 5, which is threadedly connected to the extension section. The inner end of the bolt 5 is pressed against the support rod 3 to lock the support rod 3. When unlocking, just loosen the bolt 5.

[0041] In order to increase the support surface of the support rod 3 when supporting the pottery pot, in some embodiments, as shown in FIG. Figure 2 As shown, a supporting portion 32 is provided at the top of the support rod 3. It is worth noting that the supporting portion 32 radially protrudes from the support rod 3, and the diameter of the supporting portion 32 is smaller than the diameter of the jar mouth to ensure that the supporting portion 32 can be normally inserted into the ceramic jar from the jar mouth.

[0042] The top surface of the turntable 2 has a receiving groove 21 corresponding to the supporting portion 32 , which can accommodate the supporting portion 32 . When the support rod 3 is in the first position, the supporting portion 32 is accommodated in the receiving groove 21 and does not protrude from the receiving groove 21 .

[0043] In order to avoid the support portion 32 from hard contact with the tank bottom, Figure 2 As shown, the supporting portion 32 includes a base plate 321 and a flexible component 322 provided on the top of the base plate 321. The flexible component 322 can be a rubber pad or an air bag.

[0044] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this application can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this application can be achieved. This is not a limitation herein.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0046] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
