Description

Technical Field

[0001] This application relates to the field of stationery technology, and in particular discloses a book clip. Background Technology

[0002] A book clip is a widely used stationery item designed to help readers hold the pages of a book in place while reading, thus freeing their hands. It is especially useful in situations where reading sheet music or writing while reading is required.

[0003] However, existing book clips have several problems in practical use: First, different books vary greatly in size, from pocketbooks to large picture books, and many book clips have fixed or limited adjustment openings, making them unable to effectively adapt to books of different sizes and lacking versatility; second, in order to solve the clamping problem, some products have designed complex adjustment mechanisms, but these structures are often cumbersome to operate and require a lot of time to complete the adjustment, resulting in a poor user experience; finally, considering portability and storage, many book clips with complex structures or excessive sizes are difficult to easily fit into backpacks or pencil cases, causing inconvenience to users who need to carry them with them, and therefore need to be improved. Utility Model Content

[0004] The purpose of this application is to provide a book clip.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a reading clip, comprising: a first clamping assembly, the first clamping assembly including a first support arm and a clamp, the clamp being disposed at the lower part of the first support arm, the first support arm having a plurality of positioning grooves; and a second clamping assembly, the second clamping assembly being rotatably disposed on the first support arm, the second clamping assembly including a second support arm and another clamp, the clamp being disposed at the lower part of the second support arm, the second support arm having a suspension block, the end of the suspension block having a positioning pin, the positioning pin being adapted to the positioning groove, and by engaging the positioning pin with different positioning grooves, the included angle between the second clamping assembly and the first clamping assembly can be adjusted and locked.

[0006] As a preferred embodiment, the first support arm includes an integrally formed first connecting part and a first supporting part, the first connecting part having a first through hole, the second support arm including an integrally formed second connecting part and a second supporting part, a connecting seat being provided on the rear side of the second connecting part, the outer diameter of the connecting seat being the same as the diameter of the first through hole, and the connecting seat being assembled in the first through hole.

[0007] In a further preferred embodiment, the connecting seat passes through the first through hole and is connected to the screw, and a washer is also provided between the screw and the first connecting part.

[0008] Further preferably, the first connecting part and the first supporting part are connected by a first step structure, the inner surface of the first step structure is an arc surface, and its axis coincides with the axis of the first through hole. The second connecting part and the second supporting part are connected by a second step structure, the outer surface of the second step structure is an arc surface, and its axis coincides with the axis of the connecting seat. The diameter of the outer surface of the second step structure is the same as the diameter of the inner surface of the first step structure.

[0009] Further preferably, a plurality of the positioning grooves are arranged circumferentially around the axis of the first through hole, and a second through hole is provided on the second connecting part. The suspension block includes a first suspension block and a second suspension block symmetrically formed on both sides of the second through hole. The first suspension block and the second suspension block extend towards each other, and the ends of the first suspension block and the second suspension block are both free ends. The positioning pin includes a first positioning pin provided on the end of the first suspension block and a second positioning pin provided on the end of the second suspension block. When the first positioning pin engages with any of the positioning grooves, the second positioning pin simultaneously engages with the other positioning groove. When the first clamping assembly and / or the second clamping assembly are rotated to disengage the first positioning pin and the second positioning pin from the positioning grooves, the first suspension block and the second suspension block undergo elastic deformation. When the first positioning pin and the second positioning pin engage with the corresponding positioning grooves, the first suspension block and the second suspension block return to their initial shape.

[0010] As a preferred embodiment, a first bearing seat is provided at the lower part of the first support portion. The clamp includes a clamping plate, a connecting shaft, and a torsion spring. The connecting shaft is mounted on the first bearing seat, the clamping plate is mounted on the connecting shaft, and the torsion spring is sleeved on the connecting shaft, with one end abutting against the first support portion and the other end abutting against the back side of the clamping plate. In the initial state, under the elastic force of the torsion spring, the clamping plate and the first support portion form a closed shape. Pressing the clamping plate to rotate it forms an open shape with the first support portion, and the torsion spring undergoes further deformation, accumulating elastic potential energy. After releasing the clamping plate, the torsion spring releases the elastic potential energy, causing the clamping plate to close and return to the initial state.

[0011] As a preferred embodiment, a second bearing seat is provided at the lower part of the second support portion. The clamp includes a clamping plate, a connecting shaft, and a torsion spring. The connecting shaft is mounted on the second bearing seat, the clamping plate is mounted on the connecting shaft, and the torsion spring is sleeved on the connecting shaft, with one end abutting against the second support portion and the other end abutting against the back side of the clamping plate. In the initial state, under the elastic force of the torsion spring, the clamping plate and the second support portion form a closed shape. Pressing the clamping plate to rotate it forms an open shape with the second support portion, and the torsion spring undergoes further deformation, accumulating elastic potential energy. After releasing the clamping plate, the torsion spring releases the elastic potential energy, causing the clamping plate to close and return to the initial state.

[0012] Further preferably, the clamping plate is provided with a clamping piece, one end of which is fixed to the clamping plate and the other end is suspended. There is a gap between the clamping piece and the clamping plate, and the opening direction of the clamping piece is the same as the opening direction of the clamping plate in its open state.

[0013] Further preferably, the clamp is provided with a plurality of anti-slip protrusions, the anti-slip protrusions being arranged in the same direction as the axis of the connecting shaft.

[0014] As a preferred embodiment, the first connecting portion is further provided with a plurality of protrusions, which are arranged in an array around the axis of the first through hole in a circumferential direction and are located between the first through hole and the positioning groove.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: (1) By setting multiple positioning slots on the first support arm and cooperating with the positioning pins on the suspension block of the second support arm, the user only needs to apply a small torsional force to make the positioning pin disengage from the current positioning slot. After rotating the first clamping component and / or the second clamping component to the required angle, the positioning pin will automatically be locked into the new positioning slot under the action of the elastic restoring force of the suspension block. This operation is extremely simple and quick. No tools are required to achieve stable switching of multiple preset angles, which greatly improves the versatility and ease of operation of the product.

[0016] (2) The positioning groove, suspension block and positioning pin are all integrated on the two support arms. The structure is compact and there are no complex connecting rods or large locking parts. This not only makes the operation intuitive, but also greatly reduces the overall size and redundant weight of the product, making it lighter and easier to carry and store in a schoolbag or pencil case. It perfectly solves the pain point of traditional complex adjustment mechanism reading clips being bulky and inconvenient to carry. Attached Figure Description

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] A preferred embodiment of this application, such as Figures 1 to 6 As shown, a book clip includes: a first clamping assembly, which includes a first support arm 1 and a clamp 5, the clamp 5 being disposed at the lower part of the first support arm 1, and the first support arm 1 having a plurality of positioning grooves 15; and a second clamping assembly, which is rotatably disposed on the first support arm 1, the second clamping assembly including a second support arm 2 and another clamp 5, the clamp 5 being disposed at the lower part of the second support arm 2, the second support arm 2 having a suspension block, the end of the suspension block having a positioning pin, the positioning pin being adapted to the positioning groove 15, and by engaging the positioning pin with different positioning grooves 15, the included angle between the second clamping assembly and the first clamping assembly can be adjusted and locked.

[0029] By setting multiple positioning slots 15 on the first support arm 1 and cooperating with the positioning pins on the suspension block of the second support arm 2, the user only needs to apply a small torsional force to make the positioning pin disengage from the current positioning slot 15. After rotating the first clamping component and / or the second clamping component to the desired angle, the positioning pin will automatically engage in the new positioning slot 15 under the action of the elastic restoring force of the suspension block, thus completing the locking. This operation is extremely simple and quick, and multiple preset angles can be stably switched without any tools, greatly improving the versatility and ease of operation of the product.

[0030] In this embodiment, the first support arm 1 includes an integrally formed first connecting part 11 and a first support part 12. The first connecting part 11 is provided with a first through hole 14. The second support arm 2 includes an integrally formed second connecting part 21 and a second support part 22. A connecting seat 24 is provided on the rear side of the second connecting part 21. The outer diameter of the connecting seat 24 is the same as the diameter of the first through hole 14. The connecting seat 24 is assembled in the first through hole 14.

[0031] It is understandable that the first support arm 1 and the second support arm 2 are rotatably connected by the assembly of the connecting seat 24 and the first through hole 14. In order to ensure the stability of the connection, the shape of the connecting seat 24 can be designed, and an anti-detachment protrusion ring can be set at the end of the connecting seat 24. This can ensure that the two can be connected smoothly, and that the two will not easily detach without applying a large force. This design can reduce the number of parts and make the product more portable.

[0032] In another embodiment, the connection between the first support arm 1 and the second support arm 2 can be as follows: the connecting seat 24 passes through the first through hole 14 and is connected to the screw 4. A washer 3 is also provided between the screw 4 and the first connecting part 11. The connection is stable by the screw 4, and the washer 3 is used to avoid the screw 4 from wearing on the surface of the first connecting part 11. This method is the most common in the prior art and has a simple structure.

[0033] Furthermore, the first connecting part 11 and the first supporting part 12 are connected by a first step structure. The inner surface of the first step structure is an arc surface, and its axis coincides with the axis of the first through hole 14. The second connecting part 21 and the second supporting part 22 are connected by a second step structure. The outer surface of the second step structure is an arc surface, and its axis coincides with the axis of the connecting seat 24. The diameter of the outer surface of the second step structure is the same as the diameter of the inner surface of the first step structure. During rotation, the outer surface of the second step structure and the inner surface of the first step structure can fit together, allowing the first supporting arm 1 and the second supporting arm 2 to be adjusted to the maximum angle. At the same time, it is easier to position during assembly. Of course, the diameter of the outer surface of the second step structure can also be smaller than the diameter of the inner surface of the first step structure. The specific size can be selected according to actual needs. If the diameter of the outer surface of the second step structure is larger than the diameter of the inner surface of the first step structure, the angle adjustment range of the first supporting arm 1 and the second supporting arm 2 will be reduced accordingly, but there is still a large adjustable range.

[0034] This embodiment discloses a specific configuration of an angle adjustment structure: a plurality of positioning grooves 15 are arranged circumferentially around the axis of the first through hole 14; a second through hole 215 is provided on the second connecting part 21; the suspension block includes a first suspension block 211 and a second suspension block 213 symmetrically formed on both sides of the second through hole 215; the first suspension block 211 and the second suspension block 213 extend towards each other; the ends of the first suspension block 211 and the second suspension block 213 are both free ends; the positioning pin includes a first positioning pin 212 provided on the end of the first suspension block 211 and a positioning pin 213 provided on the end of the second through hole 215. The second positioning pin 214 on the end of the two suspension blocks 213. When the first positioning pin 212 is engaged with any positioning groove 15, the second positioning pin 214 is simultaneously engaged with the other positioning groove 15. When the first clamping assembly and / or the second clamping assembly are rotated to disengage the first positioning pin 212 and the second positioning pin 214 from the positioning groove 15, the first suspension block 211 and the second suspension block 213 undergo elastic deformation. When the first positioning pin 212 and the second positioning pin 214 are engaged with the corresponding positioning groove 15, the first suspension block 211 and the second suspension block 213 return to their initial shape.

[0035] By setting a first suspension block 211 and a second suspension block 213, with one end fixed and the other end suspended as a free end, this design gives it the ability to elastically deform. Therefore, in the process of cooperating with different positioning slots 15, the first suspension block 211 and the second suspension block 213 play a role similar to a spring, ensuring that the positioning pin is smoothly lifted and lowered.

[0036] In this application, a first bearing seat 13 is provided at the lower part of the first support part 12. The clamp 5 includes a clamping plate 51, a connecting shaft 52, and a torsion spring 53. The connecting shaft 52 is mounted on the first bearing seat 13, the clamping plate 51 is mounted on the connecting shaft 52, and the torsion spring 53 is sleeved on the connecting shaft 52, with one end abutting against the first support part 12 and the other end abutting against the back side of the clamping plate 51. In the initial state, under the elastic force of the torsion spring 53, the clamping plate 51 and the first support part 12 form a closed state. After pressing the clamping plate 51 to make it rotate, it forms an open state with the first support part 12, and the torsion spring 53 undergoes further deformation, accumulating elastic potential energy. After releasing the clamping plate 51, the torsion spring 53 releases elastic potential energy, causing the clamping plate 51 to close and return to the initial state. State; The lower part of the second support 22 is provided with a second bearing seat 23. The clamp 5 includes a clamping plate 51, a connecting shaft 52 and a torsion spring 53. The connecting shaft 52 is installed on the second bearing seat 23, the clamping plate 51 is installed on the connecting shaft 52, and the torsion spring 53 is sleeved on the connecting shaft 52, with one end abutting against the second support 22 and the other end abutting against the back side of the clamping plate 51. In the initial state, under the elastic force of the torsion spring 53, the clamping plate 51 and the second support 22 form a closed state. After pressing the clamping plate 51 to make it rotate, it forms an open state with the second support 22. The torsion spring 53 undergoes further deformation and accumulates elastic potential energy. After releasing the clamping plate 51, the torsion spring 53 releases elastic potential energy, causing the clamping plate 51 to close and return to the initial state.

[0037] Furthermore, a clip 511 is provided on the clamp 51. One end of the clip 511 is fixed to the clamp 51, and the other end is suspended. There is a gap 512 between the clip 511 and the clamp 51. The opening direction of the clip 511 is the same as the opening direction of the clamp 51 when it is in the open state. The design of the clip 511 facilitates reading for the user. During reading, without the clip 511, each page turn requires pressing the clamp 51, which is inconvenient. With the clip 511, the page can be placed between the clip 511 and the clamp 51. When a page needs to be turned, the corresponding page can be directly taken out from between the clip 511 and the clamp 51 on one side and placed between the clip 511 and the clamp 51 on the other side. The operation is simple and does not require pressing the clamp 51. Similarly, the clip 511 can be used directly for temporary reading, saving time.

[0038] Furthermore, the clamping plate 51 is also provided with several anti-slip protrusions 513. The anti-slip protrusions 513 are set in the same direction as the axis of the connecting shaft 52. The anti-slip protrusions 513 make pressing the clamping plate 51 more stable and smooth.

[0039] In this embodiment, the first connecting part 11 is also provided with a plurality of protrusions 16. The protrusions 16 are arranged in an array around the axis of the first through hole 14 in the circumferential direction. They are located between the first through hole 14 and the positioning groove 15. The design of the protrusions 16 can play a certain supporting role, making the first connecting part 11 and the second connecting part 21 more stable during rotation.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
