Description

Technical Field

[0001] This utility model relates to the field of rod locking technology, and in particular to a telescopic rod locking structure. Background Technology

[0002] In traditional locking technology for thin and thick rods, the mating holes for the locking components and the mating holes for the washers are generally arranged axially, meaning the mating holes are distributed sequentially along the length of the thin rod. However, this design results in each locking segment of the thin rod being significantly shorter than the thick rod, leading to a low overall rod elongation. Furthermore, the more locking segments there are, the greater the impact on the rod's length. Utility Model Content

[0003] Therefore, it is necessary to provide a telescopic rod locking structure to address the problem that the traditional distribution of mating holes between thin and thick rods along the length results in each locking segment of the thin rod being significantly shorter than the thick rod, thus leading to a low overall elongation of the rod.

[0004] A telescopic rod locking structure includes: a first rod; a second rod disposed on the first rod, the second rod having a first mating hole and a second mating hole, the first mating hole and the second mating hole being arranged along the circumference of the second rod; a locking assembly disposed on the second rod and located at the first mating hole, the locking assembly being used to lock or unlock the first rod and the second rod; and a first washer disposed on the second rod, the first washer being located between the first rod and the second rod, a portion of the first washer being located at the second mating hole.

[0005] This application discloses a telescopic rod locking structure. The first rod is a thicker rod, and the second rod is a thinner rod. A first washer is positioned between the first and second rods, which enhances the rigidity and strength of the structure, thereby improving the overall stability. The first and second mating holes ensure a stable fit between the locking assembly and the first washer. By arranging the first and second mating holes circumferentially along the second rod, the limitation on the length of the thinner rod caused by traditional axial arrangement is avoided. This allows each section of the rod to extend more fully, significantly increasing the effective length of the overall telescopic rod. Products using this telescopic rod can achieve a smaller size and lower cost. This design allows the mating parts of the locking assembly and the first washer to be staggered, eliminating the problem of axial space occupation. While ensuring the overall rigidity and stability of the telescopic rod, it maximizes the extension rate, allowing the second rod to be shorter for the same extension length. This is significant for saving materials, reducing costs, and improving economic efficiency. This design can be applied to dryers or other products, with a wide range of applications.

[0006] In one embodiment, the first mating hole and the second mating hole are connected to form a through-hole, which is gourd-shaped. The gourd-shaped through-hole ensures that the mating points of the locking assembly and the first washer are adjacent, resulting in a more compact overall structure and better fit. Furthermore, the first and second mating holes can be formed by machining only one location, effectively improving the machining accuracy of the holes, simplifying the process, and reducing the scrap rate. This design significantly improves the overall extension rate of the telescopic rod, allowing products using this telescopic rod to have a smaller volume and reduced costs.

[0007] In one embodiment, the first mating hole and the second mating hole are arranged adjacent to each other. By arranging the first and second mating holes adjacently, their distribution can be axial or circumferential, minimizing the axial space occupied, resulting in a more compact overall structure and ensuring a good fit. This design significantly improves the overall extension rate of the telescopic rod, allowing products using this rod to achieve a smaller size and reduced costs.

[0008] In one embodiment, the first gasket is disposed around the second rod. By distributing the first gasket around the second rod, full circumferential contact is formed, effectively dispersing radial pressure during locking and avoiding localized stress concentration. This design increases the overall rigidity and strength of the structure, improving its resistance to deformation.

[0009] In one embodiment, there are multiple first gaskets, each disposed on the second member and spaced circumferentially along the second member, with each gasket located between the first member and the second member. By having multiple first gaskets located between the first member and the second member, the portion between the end of the first gasket and the second gasket can be reinforced, ensuring the rigidity and strength of the overall structure.

[0010] In one embodiment, the first gasket includes a first gasket body and a first snap-fit ​​portion. The first gasket body is disposed on the second rod, and the first snap-fit ​​portion is disposed on the first gasket body, engaging with the second mating hole. The engagement structure between the first snap-fit ​​portion and the second mating hole ensures precise fixation of the first gasket on the second rod, improving the stability of the first gasket on the second rod. Furthermore, the first snap-fit ​​portion is adjacent to the locking assembly, making the overall structure more compact.

[0011] In one embodiment, a support rib is formed on the inner side of the first gasket body, and the support rib abuts against the locking assembly, thus supporting the locking assembly. The abutment between the support rib formed on the first gasket body and the locking assembly makes the assembly of the locking assembly more stable, improving the overall stability and reliability of the product. This design has a positive effect on strengthening the product's strength and rigidity.

[0012] In one embodiment, the first gasket body has a through hole, which is disposed opposite to the first mating hole. A portion of the locking component can pass through the first mating hole and the through hole. By allowing a portion of the locking component to pass through the first mating hole and the through hole, displacement or loosening of the first gasket is effectively prevented, increasing the stability of the first gasket and preventing it from detaching.

[0013] In one embodiment, there are multiple first snap-fit ​​portions and multiple second mating holes. The number of first snap-fit ​​portions and second mating holes are the same, and the first snap-fit ​​portions and second mating holes are matched one-to-one. This design provides good mating effect, stability, and reliability.

[0014] In one embodiment, a second gasket is further included, disposed on the first member and located between the first member and the second member. By placing the second gasket on the first member and between the first and second members, the end of the first member and a portion of the second member can be reinforced, enhancing the compressive and deformation resistance of that area. The second gasket also shares some of the locking pressure, preventing excessive stress concentration at a single location and improving the overall structural reliability.

[0015] In one embodiment, one of the second washer and the first rod includes a second snap-fit ​​portion, and the other of the second washer and the first rod has a locking hole, with the second snap-fit ​​portion adapting to the locking hole. The adaptation of the second snap-fit ​​portion to the locking hole ensures that the second washer is securely fixed to the first rod, improving the stability and reliability of the second washer. This snap-fit ​​connection method simplifies the installation process of the second washer, achieving quick and accurate positioning without the need for additional fasteners, thus improving assembly efficiency.

[0016] In one embodiment, the second spacer is disposed around the second rod. By distributing the second spacer around the second rod, the overall strength and rigidity of the structure can be improved.

[0017] In one embodiment, there are multiple second gaskets, each disposed on the first member and spaced circumferentially along the second member, with each gasket located between the first and second members. By having multiple second gaskets positioned between the first and second members, the overall structural strength is improved. Preferably, the second gaskets are integral, and a design with multiple second gaskets similar to the first gasket is also within the scope of protection.

[0018] In one embodiment, the second gasket includes a second gasket body, a second snap-fit ​​portion, and a mating rib. The second gasket body is disposed on the first rod, the second snap-fit ​​portion is disposed on the second gasket body and is used to engage with the first rod, and the mating rib is disposed on the second gasket body and abuts against the first rod. The engagement of the second snap-fit ​​portion with the first rod improves the stability of the second gasket. The abutment of the mating rib against the first rod forms a tight fit structure, enhancing the overall rigidity and strength of the product and making it less prone to deformation under stress.

[0019] In one embodiment, the first rod is provided with a limiting hole. When the locking assembly locks the first rod and the second rod, a portion of the locking assembly passes through the first mating hole and the limiting hole in sequence. When the locking assembly unlocks the first rod and the second rod, the locking assembly exits from the limiting hole. By having the locking assembly pass through the first mating hole and the limiting hole, the first rod and the second rod can be stably locked. The locking method is simple, convenient, and highly reliable.

[0020] In one embodiment, the locking assembly includes a support base and a locking member. The support base is disposed on and inside the second rod, with its side abutting against the second rod and its bottom abutting against the first gasket. The locking member is disposed on the support base and is movable relative to the support base. The locking member can pass through the first mating hole and the limiting hole or exit from the limiting hole. The support base's tight abutment against the inner wall of the second rod and the first gasket, along with the side abutting against the second rod, forms a tight-fitting structure, ensuring the stability of each component. The movable locking member relative to the support base allows for locking or unlocking of the first and second rods, with simple and highly reliable locking and unlocking methods.

[0021] In one embodiment, there are two first latching parts and two second mating holes. The first latching parts and the second mating holes are matched one-to-one, and the two second mating holes are located on both sides of the first mating hole. This makes the fit more stable and improves the stability and reliability of the connection. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0049] Example 1

[0050] like Figure 1-19As shown, this embodiment discloses a telescopic rod locking structure, including: a first rod 1; a second rod 2, the second rod 2 being disposed on the first rod 1, the second rod 2 having a first mating hole 2011 and a second mating hole 2012, the first mating hole 2011 and the second mating hole 2012 being disposed along the circumference of the second rod 2; a locking assembly 3, the locking assembly 3 being disposed on the second rod 2 and located at the first mating hole 2011, the locking assembly 3 being used to lock or unlock the first rod 1 and the second rod 2; and a first washer 4, the first washer 4 being disposed on the second rod 2, the first washer 4 being located between the first rod 1 and the second rod 2, a portion of the first washer 4 being located at the second mating hole 2012.

[0051] This application discloses a telescopic rod locking structure. The first rod 1 is a thick rod, and the second rod 2 is a thin rod. A first washer 4 is positioned between the first rod 1 and the second rod 2, which enhances the rigidity and strength of the structure, thereby improving the overall stability. The first mating hole 2011 and the second mating hole 2012 ensure a stable fit between the locking assembly and the first washer 4. By arranging the first mating hole 2011 and the second mating hole 2012 circumferentially along the second rod 2, the limitation on the length of the thin rod caused by traditional axial arrangement is avoided. This allows each section of the rod to extend more fully, significantly increasing the effective length of the overall telescopic rod. This results in a smaller product size and reduced cost. This design allows the mating parts of the locking assembly 3 and the first washer 4 to be staggered, eliminating the problem of axial space occupation. While ensuring the overall rigidity and stability of the telescopic rod, it maximizes the extension rate, allowing the second rod 2 to be shorter for the same extension length. This is significant for saving materials, reducing costs, and improving economic efficiency. This design can be applied to dryers or other products, making it widely applicable.

[0052] like Figure 4 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first mating hole 2011 and the second mating hole 2012 are connected to form a mating through hole 201, which is gourd-shaped. Because the mating through hole 201 is gourd-shaped, the mating points of the locking assembly 3 and the first gasket 4 are adjacent, making the overall structure more compact and improving the mating effect. Simultaneously, the first mating hole 2011 and the second mating hole 2012 can be formed by machining only one location, effectively improving the machining accuracy of the holes, simplifying the process, and reducing the scrap rate. This design significantly improves the overall extension rate of the telescopic rod, allowing products using this telescopic rod to achieve a smaller volume and reducing costs.

[0053] In addition to the features of the above embodiments, this embodiment further specifies that the first mating hole 2011 and the second mating hole 2012 are arranged adjacent to each other. By arranging the first mating hole 2011 and the second mating hole 2012 adjacently, the distribution of the two mating holes can be axial or circumferential, minimizing the occupation of axial space, making the overall structure more compact, and ensuring the mating effect. This design can significantly improve the extension rate of the entire telescopic rod, enabling products using this telescopic rod to achieve a smaller volume and reduce costs.

[0054] like Figure 3 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first gasket 4 is arranged around the second rod 2. By arranging the first gasket 4 around the second rod 2, full circumferential contact is formed, effectively dispersing the radial pressure during locking and avoiding local stress concentration. This design enables greater rigidity and strength of the overall structure, improving the structure's resistance to deformation.

[0055] like Figure 8-12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of first gaskets 4 is multiple, and multiple first gaskets 4 are all disposed on the second rod 2 and spaced apart along the circumference of the second rod 2, and multiple first gaskets 4 are all located between the first rod 1 and the second rod 2. By having multiple first gaskets 4 located between the first rod 1 and the second rod 2, the portion between the end of the first gasket 4 and the second gasket 5 can be reinforced, ensuring the rigidity and strength of the overall structure.

[0056] like Figure 8-12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first gasket 4 includes a first gasket body 41 and a first snap-fit ​​portion 42. The first gasket body 41 is disposed on the second rod 2, and the first snap-fit ​​portion 42 is disposed on the first gasket body 41. The first snap-fit ​​portion 42 engages with the second mating hole 2012. The engaging structure between the first snap-fit ​​portion 42 and the second mating hole 2012 ensures the precise fixation of the first gasket 4 on the second rod 2, improving the stability of the first gasket 4 on the second rod 2. Moreover, the first snap-fit ​​portion 42 is adjacent to the locking assembly 3, making the overall structure more compact.

[0057] like Figure 7 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a support rib 411 is formed on the inner side of the first gasket body 41, the support rib 411 abuts against the locking assembly 3, and the support rib 411 is used to support the locking assembly 3. By having the support rib 411 formed on the first gasket body 41 abut against the locking assembly 3, the assembly of the locking assembly 3 is made more stable, improving the overall stability and reliability of the product. This design has a positive effect on strengthening the product's strength and rigidity.

[0058] like Figure 3-12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first gasket body 41 is provided with a through hole 401, the through hole 401 is disposed opposite to the first mating hole 2011, and a portion of the locking component 3 can pass through the first mating hole 2011 and the through hole 401. Because a portion of the locking component 3 can pass through the first mating hole 2011 and the through hole 401, displacement or loosening of the first gasket 4 is effectively prevented, increasing the stability of the first gasket 4 and preventing detachment.

[0059] In addition to the features of the above embodiments, this embodiment further specifies that: the number of first latching parts 42 is multiple, the number of second mating holes 2012 is multiple, the number of first latching parts 42 and second mating holes 2012 is the same, and the first latching parts 42 and the second mating holes 2012 are matched one-to-one. This design has good mating effect, stability, and reliability.

[0060] like Figure 3-4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further includes a second gasket 5, which is disposed on the first rod 1 and located between the first rod 1 and the second rod 2. By disposing of the second gasket 5 on the first rod 1 and located between the first rod 1 and the second rod 2, the end of the first rod 1 and a portion of the second rod 2 can be reinforced, enhancing the compressive and deformation resistance of that portion. The second gasket 5 shares part of the locking pressure, preventing excessive stress concentration at a single location and improving the overall structural reliability.

[0061] like Figure 15 and Figure 16As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one of the second gasket 5 and the first rod 1 includes a second snap-fit ​​portion 52, and the other of the second gasket 5 and the first rod 1 is provided with a snap-fit ​​hole 101, the second snap-fit ​​portion 52 being adapted to the snap-fit ​​hole 101. By adapting the second snap-fit ​​portion 52 to the snap-fit ​​hole 101, the second gasket 5 is securely fixed to the first rod 1, improving the stability and reliability of the second gasket 5. This snap-fit ​​connection method simplifies the installation process of the second gasket 5, achieving quick and accurate positioning without additional fasteners, thus improving assembly efficiency.

[0062] like Figure 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second gasket 5 is located inside the second rod 2. By surrounding the second rod 2 with the second gasket 5, the strength and rigidity of the overall structure can be better improved.

[0063] In addition to the features of the above embodiments, this embodiment further specifies that: the number of second gaskets 5 is multiple, and the multiple second gaskets 5 are all disposed on the first rod 1 and spaced apart circumferentially along the second rod 2, and the multiple second gaskets 5 are all located between the first rod 1 and the second rod 2. By having multiple second gaskets 5 located between the first rod 1 and the second rod 2, the strength of the overall structure can be improved. The second gasket 5 is preferably a single piece, and a design with multiple second gaskets 5 similar to the first gasket 4 is also within the scope of protection.

[0064] like Figure 6 and Figure 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second gasket 5 includes a second gasket body 51, a second snap-fit ​​portion 52, and a mating rib 53. The second gasket body 51 is disposed on the first rod 1, the second snap-fit ​​portion 52 is disposed on the second gasket body 51, and the second snap-fit ​​portion 52 is used to cooperate with the first rod 1. The mating rib 53 is disposed on the second gasket body 51 and abuts against the first rod 1. By using the second snap-fit ​​portion 52 to cooperate with the first rod 1, the stability of the second gasket 5 can be improved. By using the mating rib 53 to abut against the first rod 1, a tight-fitting structure is formed, improving the overall rigidity and strength of the product, making it less prone to deformation under stress.

[0065] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first rod 1 is provided with a limiting hole 102; when the locking assembly 3 locks the first rod 1 and the second rod 2, a portion of the locking assembly 3 passes through the first mating hole 2011 and the limiting hole 102 in sequence; when the locking assembly 3 unlocks the first rod 1 and the second rod 2, the locking assembly 3 exits from the limiting hole 102. By having the locking assembly 3 pass through the first mating hole 2011 and the limiting hole 102, the first rod 1 and the second rod 2 can be stably locked, the locking method is simple and convenient, and the locking reliability is high.

[0066] like Figure 18 and Figure 19 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the locking assembly 3 includes a support base 31 and a locking member 32. The support base 31 is disposed on the second rod 2 and located inside the second rod 2. The side of the support base 31 abuts against the second rod 2, and the bottom of the support base 31 abuts against the first gasket 4. The locking member 32 is disposed on the support base 31 and is movable relative to the support base 31. The locking member 32 can pass through the first mating hole 2011 and the limiting hole 102 or exit from the limiting hole 102. The support base 31 abuts tightly against the inner wall of the second rod 2 and the first gasket 4, and the side of the support base 31 abuts against the second rod 2, forming a tight-fitting structure, ensuring the stability of each component. The locking member 32 is movable relative to the support base 31, allowing locking or unlocking of the first rod and the second rod by moving the locking member 32. The locking and unlocking methods are simple and highly reliable.

[0067] Example 2

[0068] like Figure 5 , Figure 11-12 and Figure 14 As shown, there are two first latching parts 42 and two second mating holes 2012. The first latching parts 42 and the second mating holes 2012 are mated in a one-to-one correspondence, and the two second mating holes 2012 are located on both sides of the first mating hole 2011. This makes the mating more stable and improves the stability and reliability of the connection.

[0069] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
