Description

Technical Field

[0001] This application relates to the field of electronic remote control equipment technology, and more specifically to a page turner. Background Technology

[0002] In today's multimedia teaching, business presentations, conference reports, and various public speaking occasions, presentations often rely on the speaker manually operating the buttons on the computer or projector to switch slides. This requires the speaker to frequently return to the computer, affecting the presentation's effectiveness and the audience's concentration. Therefore, a slide turner has emerged. A slide turner is a portable, wireless presentation aid that connects wirelessly to a computer or other presentation equipment, allowing the speaker to easily control slides, pause, and play them using simple button operations, even when away from the device. This provides the speaker with a more free and fluid presentation experience. For example, Chinese utility model patent CN209118237U discloses a detachable laser page turner, including a first outer shell, a second outer shell at the bottom of the first outer shell, a circuit board installed inside the second outer shell, and a battery located at one end of the circuit board inside the second outer shell. Four screws are embedded in a rectangle at the bottom of the second outer shell, and a laser probe is embedded in the inner side of the first and second outer shells near the laser cap. In this technical solution, the first and second outer shells are fixed together by screws passing through the threaded groove and the internal threaded post in sequence, so that they can be disassembled and repaired. However, the first and second outer shells are connected by screws, which requires multiple screw tightening operations during the production process. This not only increases the assembly steps, but also easily leads to uneven screw tightening force, which may cause the shell to loosen or be damaged. Although the detachable design facilitates maintenance, the disassembly process of the screw connection is also cumbersome. Maintenance personnel need to loosen the screws one by one, which is not only time-consuming, but may also increase the difficulty of disassembly due to screw corrosion or damage. Therefore, there is a need for a page-turning pen that can achieve quick and reliable connection between the shells. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a page turner pen that achieves quick assembly by inserting the second housing into the opening of the first housing and connecting it with the buckle of the latch using a locking structure. This simplifies the assembly steps, eliminates the need for additional materials such as screws, nuts or glue, reduces assembly time, and lowers production costs.

[0004] This application provides a page turner pen, including a first housing and a second housing. One end of the first housing is provided with a first opening for the second housing to pass through. The second housing passes through the first opening to be sleeved with the first housing. The second housing is provided with a locking structure. The first housing is provided with a buckle adapted to the locking structure. The locking structure and the buckle are snapped together in the insertion direction to lock the second housing and the first housing.

[0005] In this technical solution, a first opening is provided on the first housing, and the second housing is inserted into the first housing through the first opening to achieve a sleeve connection between the two. A locking structure is provided on the second housing, while a latching position is provided on the first housing. During the insertion of the second housing into the first housing, the locking structure and the latching position are engaged along the insertion direction to lock the first and second housings. This snap-fit ​​connection method allows for rapid assembly without the need for screws or other fasteners, greatly reducing assembly time and operational complexity, and improving production efficiency. By inserting the second housing into the opening of the first housing and utilizing the snap-fit ​​connection between the locking structure and the latching position, rapid assembly is achieved, simplifying the process. The assembly process is streamlined, reducing reliance on tools and eliminating the need for additional materials such as screws, nuts, or glue. This reduces manual operation time and lowers production costs. The snap-fit ​​connection has high stability under normal use conditions and will not loosen due to vibration or frequent operation, maintaining a good connection state during long-term use. The page turner of this application also includes a third housing. One side of the second housing is sleeved with the first housing, and the other side of the second housing is sleeved with the third housing. The first and third housings are both outer housings of the page turner, while the second housing is the internal structure of the page turner, used to fix internal components. The overall structure is more reliable and aesthetically pleasing.

[0006] As an improvement, the first housing is a metal housing, and the second housing is a plastic housing. In this technical solution, the first housing is the outer housing of the page turner, made of metal. Metal has high strength and durability, providing better protection and structural stability for the page turner as a whole. The second housing is the internal structure of the page turner, used to fix internal components. The second housing is made of plastic, which has good processing performance and elasticity, allowing for complex structural designs through injection molding. Since metal housings cannot be processed into complex elastic structures, while plastic housings can be injection molded into complex elastic structures, combining the metal and plastic housings allows the elasticity of the plastic housing to be used to fix the two, thus achieving rapid assembly and locking of the two housings. This not only solves the problem of metal housings being unable to process complex structures but also provides a simple, reliable, and efficient fixing method, offering advantages such as reduced production costs, improved assembly efficiency, enhanced product reliability, and improved user experience.

[0007] As an improvement, the second housing is provided with a first protrusion, and the first housing is provided with a first limiting part adapted to the first protrusion. The first protrusion abuts against the first limiting part to restrict the movement of the second housing within the first housing along the insertion direction. In this technical solution, by providing a mutually cooperating first protrusion and first limiting part on the second housing and the first housing respectively, the first protrusion contacts and is blocked by the first limiting part during insertion, preventing the second housing from moving excessively within the first housing along the insertion direction. The cooperation between the first protrusion and the first limiting part plays a positioning role during assembly, ensuring that the second housing can be accurately inserted into the first housing and restricted at a predetermined position, ensuring the relative position between the two housings is stable, avoiding assembly problems caused by positional deviations, and also preventing the second housing from moving along the insertion direction due to vibration or other external forces during use, thereby enhancing the stability of the overall structure, improving assembly accuracy and structural stability, and simplifying the assembly process.

[0008] As an improvement, a guide strip adapted to the second housing is provided inside the first housing. The guide strip guides the insertion of the second housing and is connected to the second housing to restrict the circumferential movement of the second housing within the first housing. In this technical solution, the guide strip inside the first housing primarily guides the insertion of the second housing, ensuring it can be smoothly inserted into the first housing along a predetermined direction, avoiding misalignment or jamming during insertion, and improving assembly consistency and reliability. The guide strip is designed to match the outer circumferential shape of the second housing; that is, the second housing typically has grooves or tracks corresponding to the guide strip, allowing the second housing to be smoothly inserted into the first housing along the guide strip. Guided by the guide strip, the second housing can be quickly and accurately inserted into the first housing, reducing assembly time and improving production efficiency. The connection between the guide strip and the second housing restricts the movement of the second housing within the first housing in the circumferential direction. The circumferential movement within the housing ensures the relative position stability between the two housings, preventing the second housing from rotating during use and thus enhancing the overall structural stability. Preferably, two guide bars are provided, offering more stable guidance and support. These two guide bars are typically symmetrically distributed inside the first housing and are adapted to corresponding structures (such as grooves or tracks) on the second housing. This ensures that the second housing can move smoothly along a predetermined path during insertion, making the insertion process smoother and more accurate, reducing the possibility of skewing, and more effectively preventing the second housing from moving circumferentially within the first housing, thereby enhancing the overall structural stability.

[0009] As an improvement, the locking structure is an elastic snap-fit ​​on the second housing, and the latching position is a groove on the first housing. In this technical solution, by setting the locking structure as an elastic snap-fit, the locking structure can undergo elastic deformation during insertion and return to its original shape when it reaches the latching position, thereby achieving locking. The latching position is a groove, the shape and size of which are adapted to the elastic snap-fit ​​to accommodate and fix it. During the insertion of the second housing into the first housing, the elastic snap-fit ​​will contact the inner wall of the first housing and undergo elastic deformation. When the elastic snap-fit ​​reaches the groove position, it returns to its original shape and embeds itself in the groove, thereby achieving locking between the second housing and the first housing. The cooperation between the elastic snap-fit ​​and the groove allows for quick assembly without the need for tools or screws, greatly reducing assembly time and operational complexity. It also eliminates the need for screws, nuts, or other fasteners, reducing material costs.

[0010] As an improvement, the locking structure is provided with a guide ramp adapted to the latching position. The guide ramp is used to guide the connection between the locking structure and the latching position. In this technical solution, the guide ramp on the locking structure plays a guiding role during the insertion of the locking structure into the latching position, ensuring that the locking structure can smoothly enter the latching position during insertion, reducing resistance during insertion, improving assembly efficiency, avoiding hard collisions between the locking structure and the latching position, thereby enhancing the stability of the overall structure, reducing damage to the locking structure or latching position caused by impacts during insertion, and extending the service life of the product.

[0011] As an improvement, the second housing is provided with a clearance groove surrounding the locking structure, and the locking structure is elastic through the clearance groove. In this technical solution, the clearance groove surrounds the locking structure, so that part of the locking structure is separated from the second housing. The locking structure is elastic through the clearance groove, and the design of the clearance groove provides space for elastic deformation of the locking structure, so that the locking structure can smoothly engage with the latch during insertion and locking, reducing assembly difficulties caused by hard collisions, improving assembly accuracy and reliability. The clearance groove design allows the locking structure to undergo elastic deformation during insertion, reducing insertion resistance.

[0012] As an improvement, the first protrusion is disposed on the outer wall of the second housing and extends circumferentially along the second housing, and the first limiting part is a stepped structure disposed on the inner wall of the first housing. In this technical solution, the first protrusion forms an annular protrusion on the outer surface of the second housing, and the first limiting part is a stepped structure, which is a horizontal protrusion. The first limiting part abuts against the first protrusion, restricting the movement of the second housing within the first housing along the insertion direction, ensuring the relative position between the two housings is stable. The structural design is simple and ingenious, and the fit is more reliable.

[0013] As an improvement, a second protrusion is provided at the other end of the first housing, and a positioning groove adapted to the second protrusion is provided on the second housing. The second protrusion connects with the positioning groove to position the second housing within the first housing. In this technical solution, the second protrusion is provided at the other end of the first housing to cooperate with the positioning groove on the second housing. The main function of the second protrusion is to restrict the movement of the second housing within the first housing after it is inserted into the first housing, ensuring stable installation. The cooperation between the second protrusion and the positioning groove ensures that the second housing can be precisely aligned after being inserted into the first housing, reducing human error during assembly, improving assembly consistency and reliability, guiding the second housing into the predetermined position, reducing assembly time, and improving production efficiency.

[0014] As an improvement, the positioning groove is trapezoidal in shape. In this technical solution, the positioning groove is trapezoidal, meaning that its two sides are of different lengths, with one end being wider and the other narrower. The trapezoidal positioning groove provides a larger insertion space, facilitating the smooth entry of the second protrusion. The trapezoidal positioning groove can quickly guide the second protrusion into the predetermined position, further simplifying the assembly process, reducing assembly time, and improving production efficiency.

[0027] like Figures 1 to 7As shown, this application discloses a page turner pen, including a first housing 1 and a second housing 2. One end of the first housing 1 has a first opening 11 through which the second housing 2 passes. The second housing 2 passes through the first opening 11 to engage with the first housing 1. The second housing 2 is provided with a locking structure 21, and the first housing 1 is provided with a latching position 12 adapted to the locking structure 21. The locking structure 21 and the latching position 12 are snapped together in the insertion direction to lock the second housing 2 and the first housing 1. The first opening 11 allows the second housing 2 to be inserted into the first housing 1, achieving the engagement. The locking structure 21 on the second housing 2 and the latching position 12 on the first housing 1 allow for quick assembly during insertion. The absence of screws or other fasteners significantly reduces assembly time and operational complexity, improving production efficiency. Quick assembly is achieved by inserting the second housing 2 into the opening of the first housing 1 and connecting it to the latch 12 using the locking structure 21. This simplifies assembly steps, reduces reliance on tools, and eliminates the need for additional materials such as screws, nuts, or glue, thus reducing manual operation time and production costs. The latch connection exhibits high stability under normal use conditions, preventing loosening due to vibration or frequent operation and maintaining a good connection over long-term use. The page turner also includes a third housing 3. One side of the second housing 2 is fitted onto the first housing 1, and the other side of the second housing 2 is fitted onto the third housing 3. Both the first housing 1 and the third housing 3 are the outer housings of the page turner, while the second housing 2 is the internal structure used to secure internal components. The overall structure is more reliable and aesthetically pleasing.

[0028] More specifically, the first shell 1 is a metal shell, and the second shell 2 is a plastic shell. The first shell 1 is the outer shell of the page turner, and its metal material provides high strength and durability, offering better protection and structural stability for the page turner as a whole. The second shell 2 is the internal structure of the page turner, used to fix internal components. Its plastic material has good processing performance and elasticity, allowing for complex structural designs through injection molding. Since metal shells cannot be processed into complex elastic structures, while plastic shells can be injection molded to achieve complex elastic structures, combining the metal shell and the plastic shell utilizes the elasticity of the plastic shell to fix both, thus enabling rapid assembly and locking of the two shells. This not only solves the problem of metal shells being unable to process complex structures but also provides a simple, reliable, and efficient fixing method, offering advantages such as reduced production costs, improved assembly efficiency, enhanced product reliability, and improved user experience.

[0029] More specifically, such as Figures 2 to 4 and Figure 6 As shown, a first protrusion 22 is provided on the second housing 2, and a first limiting part 13 adapted to the first protrusion 22 is provided inside the first housing 1. The first protrusion 22 abuts against the first limiting part 13 to restrict the movement of the second housing 2 in the first housing 1 along the insertion direction. By providing the first protrusion 22 and the first limiting part 13 that cooperate with each other on the second housing 2 and the first housing 1 respectively, the first protrusion 22 will contact and be blocked by the first limiting part 13 during the insertion process, preventing the second housing 2 from moving excessively in the first housing 1 along the insertion direction. The cooperation of the first protrusion 22 and the first limiting part 13 plays a positioning role during the assembly process, ensuring that the second housing 2 can be accurately inserted into the first housing 1 and restricted at a predetermined position, ensuring the relative position between the two housings is stable, avoiding assembly problems caused by position deviation, and also preventing the second housing 2 from moving along the insertion direction due to vibration or other external forces during use, thereby enhancing the stability of the overall structure, improving the assembly accuracy and structural stability, and simplifying the assembly process.

[0030] More specifically, such as Figure 3 and Figure 7 As shown, a guide strip 14 adapted to the second housing 2 is provided inside the first housing 1. The guide strip 14 is used to guide the insertion of the second housing 2. The guide strip 14 is connected to the second housing 2 to restrict the movement of the second housing 2 in the circumferential direction within the first housing 1. The main function of the guide strip 14 is to guide the insertion of the second housing 2, ensuring that the second housing 2 can be smoothly inserted into the first housing 1 in a predetermined direction, avoiding deviation or jamming during the insertion process, and improving the consistency and reliability of assembly. The design of the guide strip 14 is adapted to the outer circumferential shape of the second housing 2, that is, the second housing 2 usually has a groove or track corresponding to the guide strip 14, so that the second housing 2 can be smoothly inserted into the first housing 1 along the guide strip 14. With the guidance of the guide strip 14, the second housing 2 can be quickly and accurately inserted into the first housing 1. The first housing 1 is inserted into the first housing 1, reducing assembly time and improving production efficiency. The connection between the guide bar 14 and the second housing 2 restricts the movement of the second housing 2 in the circumferential direction within the first housing 1, ensuring the relative position between the two housings is stable and preventing the second housing 2 from rotating during use, thereby enhancing the stability of the overall structure. Two guide bars 14 are provided, which provide more stable guidance and support. The two guide bars 14 are usually symmetrically distributed inside the first housing 1 and are adapted to the corresponding structures (such as grooves or tracks) on the second housing 2, ensuring that the second housing 2 can move smoothly along the predetermined path during insertion, ensuring a smoother and more accurate insertion process, reducing the possibility of deflection, and more effectively preventing the second housing 2 from moving in the circumferential direction within the first housing 1, thus enhancing the stability of the overall structure.

[0031] More specifically, such as Figure 3 , Figure 4 and Figure 6 As shown, the locking structure 21 is an elastic buckle set on the second housing 2, and the buckle position 12 is a groove set on the first housing 1. By setting the locking structure 21 as an elastic buckle, the locking structure 21 can undergo elastic deformation during insertion and return to its original shape when it reaches the buckle position 12, thereby achieving locking. The buckle position 12 is a groove, the shape and size of which are adapted to the elastic buckle to accommodate the elastic buckle and achieve fixation. During the process of the second housing 2 being inserted into the first housing 1, the elastic buckle will contact the inner wall of the first housing 1 and undergo elastic deformation. When the elastic buckle reaches the groove position, the elastic buckle returns to its original shape and is embedded in the groove, thereby achieving locking between the second housing 2 and the first housing 1. The cooperation between the elastic buckle and the groove can achieve quick assembly without the use of tools or screws, greatly reducing assembly time and operational complexity. It also eliminates the need for screws, nuts or other fasteners, reducing material costs.

[0032] More specifically, such as Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the locking structure 21 is provided with a guide slope 211 adapted to the latch 12. The guide slope 211 is used to guide the connection between the locking structure 21 and the latch 12. The guide slope 211 on the locking structure 21 plays a guiding role during the insertion of the locking structure 21 into the latch 12, ensuring that the locking structure 21 can smoothly enter the latch 12 during the insertion process, reducing the resistance during the insertion process, improving the assembly efficiency, avoiding hard collisions between the locking structure 21 and the latch 12, thereby enhancing the stability of the overall structure, reducing the damage to the locking structure 21 or the latch 12 caused by the impact during the insertion process, and extending the service life of the product.

[0033] More specifically, such as Figure 4 , Figure 6 and Figure 7 As shown, the second housing 2 is provided with a clearance groove 23 surrounding the locking structure 21. The locking structure 21 is elastic through the clearance groove 23. The clearance groove 23 surrounds the locking structure 21 so that part of the locking structure 21 is separated from the second housing 2. The design of the clearance groove 23 provides space for the locking structure 21 to deform elastically, so that the locking structure 21 can smoothly cooperate with the latch 12 during insertion and locking, reducing assembly difficulties caused by hard collisions and improving assembly accuracy and reliability. The clearance groove 23 design allows the locking structure 21 to undergo elastic deformation during insertion, reducing insertion resistance.

[0034] More specifically, such as Figure 3 and Figure 4 As shown, the first protrusion 22 is disposed on the outer wall of the second housing 2 and extends circumferentially along the second housing 2. The first limiting part 13 is a stepped structure disposed on the inner wall of the first housing 1. The first protrusion 22 forms an annular protrusion on the outer surface of the second housing 2. The first limiting part 13 is a stepped structure, which is a horizontal protrusion. The first limiting part 13 abuts against the first protrusion 22, restricting the movement of the second housing 2 in the first housing 1 along the insertion direction, ensuring the relative position between the two housings is stable. The structural design is simple and ingenious, and the fit is more reliable.

[0035] More specifically, such as Figure 3 , Figure 4 and Figure 7 As shown, a second protrusion 15 is provided at the other end of the first housing 1, and a positioning groove 24 adapted to the second protrusion 15 is provided on the second housing 2. The second protrusion 15 is connected to the positioning groove 24 so that the second housing 2 is positioned and installed in the first housing 1. The second protrusion 15 is provided at the other end of the first housing 1 and is used to cooperate with the positioning groove 24 on the second housing 2. The main function of the second protrusion 15 is to cooperate with the positioning groove 24 after the second housing 2 is inserted into the first housing 1, restrict the movement of the second housing 2 in the first housing 1, and ensure its stable installation. The cooperation between the second protrusion 15 and the positioning groove 24 can ensure that the second housing 2 can be accurately aligned after being inserted into the first housing 1, reduce human error in the assembly process, improve the consistency and reliability of assembly, guide the second housing 2 into the predetermined position, reduce assembly time, and improve production efficiency.

[0036] More specifically, such as Figure 7 As shown, the positioning groove 24 has a trapezoidal structure. The positioning groove 24 with a trapezoidal structure means that the lengths on both sides are different, with one end being wider and the other end being narrower. The positioning groove 24 with a trapezoidal structure provides a larger insertion space, which facilitates the smooth entry of the second protrusion 15. The positioning groove 24 with a trapezoidal structure can quickly guide the second protrusion 15 into the predetermined position, further simplifying the assembly process, reducing assembly time, and improving production efficiency.

[0037] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
