Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of brush for archaeology, specifically to a new brush for archaeology beneficial to the protection of cultural relics. BACKGROUND

[0002] In the archaeological work, cleaning cultural relics is a crucial and delicate work. Since cultural relics have very high historical, cultural and artistic value, they may be fragile, so extra care is needed in the cleaning process to avoid damaging the cultural relics.

[0003] At present, the traditional brush for archaeology has many deficiencies. First, the brushing force of most traditional brushes for archaeology is fixed and cannot be flexibly adjusted according to the material quality, fragility and surface impurity adhesion of cultural relics. It is completely operated according to the operator's feeling, which is not suitable for beginners. When cleaning some cultural relics with fragile texture, the larger brushing force may scratch, wear or even damage the surface of the cultural relics. When cleaning cultural relics with firmly attached impurities, the smaller brushing force is difficult to achieve the desired cleaning effect. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides a new brush for archaeology beneficial to the protection of cultural relics.

[0005] In order to achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] A new brush for archaeology beneficial to the protection of cultural relics comprises:

[0007] A brush handle has a hollow shell connected at one end, and a longitudinal through slot is formed in the side of the shell;

[0008] A movable column is axially slidably arranged in the interior of the brush handle and the shell, and the first end of the movable column extends into the interior of the shell and is provided with an archaeology brush head;

[0009] A threaded rod is rotatably connected to the second end of the movable column, and the threaded rod is threadedly connected with the end wall of the brush handle;

[0010] An auxiliary assembly comprises an L-shaped plate rotatably connected to the shell by a rotating shaft, a torsional spring is sleeved on the rotating shaft, the free end of the L-shaped plate is provided with a plurality of spaced-apart clamping teeth, the clamping teeth extend into the through slot of the shell, and the gap between adjacent clamping teeth is equal to the diameter of the brush bristles of the brush head.

[0011] Preferably, the clamping teeth are made of hard rubber, and the bottom end of the clamping teeth is provided with a pointed end, and the width of the outer side of the clamping teeth is slightly larger than the width of the inner side.

[0012] Preferably, the L-shaped plate is provided with a pressing part inclined to the brush handle, and the L-shaped plate is separated from the shell by rotating around the rotating shaft against the pre-tightening force of the torsional spring when the pressing part is pressed.

[0013] Preferably, the moving column is a polygonal column, and the diameter of the circumscribed circle of the polygonal column is greater than the diameter of the threaded rod.

[0014] Preferably, the moving column is a polygonal column with a regular hexagonal cross section, and the diameter of the circumscribed circle of the polygonal column is 1.2-1.5 times greater than the diameter of the threaded rod, and the inner cavity of the brush handle is provided with a guide sliding groove matched with the polygonal column.

[0015] Preferably, the threaded rod is connected with the moving column through a bearing.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] 1. The brush force can be adjusted: the moving column is driven to move axially in the brush handle and the shell by rotating the threaded rod, so that the length of the brush head extending out of the shell can be adjusted, thereby changing the length of the brush hairs extending out of the brush head, and the length of the brush hairs extending out of the brush head is negatively correlated with the brush force, so that the brush force can be flexibly adjusted according to the actual archaeological cleaning requirements.

[0018] 2. The structure is stable: the moving column is a polygonal column (such as a regular hexagonal polygonal column), and the diameter of the circumscribed circle of the polygonal column is 1.2-1.5 times greater than the diameter of the threaded rod, and the inner cavity of the brush handle is provided with a matched guide sliding groove, which can ensure the stable sliding of the moving column and prevent it from rotating in the brush handle, thereby ensuring the stability of the entire structure and the precision of the operation.

[0019] 3. The brush head can be automatically cleaned: during the process of the brush head entering the shell, the clamping teeth can extrude and clean the brush hairs of the brush head, thereby removing the dirt and other impurities on the brush hairs, ensuring the cleanliness of the brush head for next use, reducing the trouble of manual cleaning, and maintaining good cleaning effect.

[0020] 4. The operation is convenient: the L-shaped plate of the auxiliary assembly is provided with a pressing part, and the L-shaped plate can be separated from the shell by rotating around the rotating shaft against the pre-tightening force of the torsional spring when the pressing part is pressed, so that the brush head can be conveniently extended out when needed, the clamping teeth do not affect the brush head, and the operation is simple and convenient.

[0021] 5. The components are protected: the hollow shell accommodates part of the structure of the moving column and the brush head, thereby protecting and supporting the internal components and prolonging the service life of the archaeological brush. BRIEF DESCRIPTION OF DRAWINGS

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1-4 As shown, a new type of archaeological brush that is beneficial for protecting cultural relics includes:

[0031] Brush handle 1: One end is connected to a hollow housing 2, which is the handheld part and provides a grip for the entire tool. Its interior has a structure that mates with the moving column 3, ensuring that the moving column 3 can slide axially within it.

[0032] Housing 2: A longitudinal through groove is provided on the side for cooperation with auxiliary components. The internal space accommodates part of the structure of the movable column 3 and the brush head 6, serving to protect and support the internal components.

[0033] The moving column 3 is axially slidably arranged in the brush handle 1 and the shell 2. The first end of the moving column 3 extends into the shell 2 and is provided with the brush head 6 for archeological use. By sliding in the brush handle 1 and the shell 2, the length of the brush head 6 extending out of the shell 2 can be adjusted, so that the length of the bristles of the brush head 6 extending out is different, and the longer the length of the bristles extending out, the smaller the brushing force of the brush, that is, the length of the bristles extending out is negatively correlated with the brushing force. The moving column 3 has a polygonal structure, for example, a polygonal structure with a hexagonal cross section, and the diameter of the circumscribed circle of the polygonal structure is 1.2-1.5 times larger than the diameter of the threaded rod 4, and the inner cavity of the brush handle 1 is provided with a guide sliding groove matched with the polygonal structure, so that the moving column 3 can stably slide and is prevented from rotating in the brush handle 1.

[0034] The threaded rod 4 is rotationally connected to the second end of the moving column 3. By cooperating with the threads of the end wall of the brush handle 1, when the threaded rod 4 is rotated, the moving column 3 can be driven to axially move in the brush handle 1 and the shell 2, so as to adjust the position of the brush head 6. The threaded rod 4 is connected to the moving column 3 through the bearing 5, so that when the threaded rod 4 is rotated, the moving column 3 is not rotated, and it is ensured that the moving column 3 only axially moves.

[0035] The brush head 6 is mounted on the first end of the moving column 3 extending into the shell 2, and is the part directly contacting the cultural relics for cleaning work. The brush head 6 is specially designed according to the requirements of archeological work, and can effectively clean the impurities on the surface of the cultural relics while minimizing the damage to the cultural relics. During the process of the brush head 6 entering the shell 2, the L-shaped plate 21 and the clamping teeth 24 do not need to be turned open. During the process of the brush head 6 entering the shell 2, the clamping teeth 24 can extrude and clean the bristles of the brush head 6, so as to remove the dirt and other impurities on the bristles of the brush head 6 and ensure the cleanliness of the next use. When the brush head 6 needs to be extended, the L-shaped plate 21 needs to be turned open to avoid the influence of the clamping teeth 24 on the brush head 6.

[0036] The auxiliary assembly includes the L-shaped plate 21 rotationally connected to the shell 2 through the rotating shaft 22, and the torsional spring 23 is sleeved on the rotating shaft 22. The free end of the L-shaped plate 21 is provided with a plurality of clamping teeth 24 arranged at intervals, and the clamping teeth 24 extend into the through slot of the shell 2. The gap between adjacent clamping teeth 24 is equal to the diameter of the bristles of the brush head 6. The clamping teeth 24 are made of hard rubber, the bottom end is provided with a pointed end, and the width of the side facing outward is slightly larger than the width of the side facing inward. The L-shaped plate 21 is provided with a pressing portion inclined to the brush handle 1. When the pressing portion is pressed, the L-shaped plate 21 can rotate around the rotating shaft 22 and separate from the shell 2 by overcoming the pre-tightening force of the torsional spring 23.

[0037] Holding and overall structure support: The user holds the brush handle 1, and the brush handle 1 serves as the holding basis of the whole tool and provides a stable force point for operation. The internal structure cooperates with the moving column 3 to ensure that the moving column 3 can smoothly axially slide therein. The hollow shell 2 is connected to one end of the brush handle 1, and not only accommodates part of the structure of the moving column 3 and the brush head 6, but also protects and supports the internal components. The longitudinal through slot on the side is used in cooperation with the auxiliary assembly.

[0038] Brush head 6 length adjustment: when the length of the brush head 6 extending out of the shell 2 needs to be adjusted to change the length of the bristles exposed to adjust the brushing force, rotate the threaded rod 4. Since the threaded rod 4 is threadedly connected with the end wall of the brush handle 1 and connected with the moving column 3 through the bearing 5, when the threaded rod 4 is rotated, the moving column 3 will not be rotated, but will be driven to move axially in the brush handle 1 and the shell 2. The moving column 3 adopts a polygonal structure (such as a polygonal prism with a hexagonal cross section), and the diameter of the circumscribed circle is 1.2-1.5 times larger than the diameter of the threaded rod 4, and at the same time, the inner cavity of the brush handle 1 is provided with a matching guide sliding groove, which not only ensures that the moving column 3 can stably slide axially, but also prevents it from rotating in the brush handle 1, and ensures that the moving column 3 adjusts the position of the brush head 6 in the expected manner.

[0039] Cultural relic cleaning operation: after adjusting the position of the brush head 6, the brush head 6 installed on the first end of the moving column 3 and extending out of the shell 2 is used to contact the surface of the cultural relic to perform cleaning work. The brush head 6 is specially designed according to the requirements of archaeological work, and can effectively clean the impurities on the surface of the cultural relic while minimizing the damage to the cultural relic.

[0040] Brush head 6 cleaning: during the process of the brush head 6 entering the shell 2, the L-shaped plate 21 and the clamping teeth 24 do not need to be turned open. Since the gap between adjacent clamping teeth 24 is equal to the diameter of the bristles of the brush head 6, and the clamping teeth 24 are made of hard rubber, the bottom end is provided with a sharp end, and the width of the side facing the outside is slightly larger than the width of the side facing the inside, when the brush head 6 enters, the clamping teeth 24 can extrude and clean the bristles of the brush head 6 to remove the dirt and other impurities on the bristles, and ensure the cleanliness of the next use. When the brush head 6 needs to be extended, press the pressing part of the L-shaped plate 21 inclined to the brush handle 1, the L-shaped plate 21 overcomes the pre-tightening force of the torsional spring 23 and rotates around the rotating shaft 22 to separate from the shell 2, so as to avoid the influence of the clamping teeth 24 on the extension of the brush head 6.

[0041] The technical scope of the present application is not limited to the content described in the above description, and those skilled in the art can make various modifications and modifications to the above embodiments without departing from the technical concept of the present application, and these modifications and modifications should be within the protection scope of the present application.
