Description

Technical Field

[0001] This application relates to the field of telescopic pole technology, and in particular to a telescopic pole adjustment mechanism and an electric fan. Background Technology

[0002] Telescopic rods are a common device in people's daily lives. The common solution is to use screws to lock the telescopic rod in place. This is done by rotating the screws inward, squeezing the metal rod, reducing the gap, and increasing friction. This solution requires the user to operate with both hands, resulting in a poor user experience. In addition, the screws are large and protrude, which has a significant impact on the appearance. Summary of the Invention

[0003] To address the aforementioned issues, this application provides a telescopic rod adjustment mechanism that uses a snap ring locking structure to achieve telescopic rod adjustment, making it convenient for users to operate. Furthermore, the snap ring is designed inside the outer tube, eliminating exposed structures and enhancing the aesthetic appeal of the telescopic rod.

[0004] This application embodiment provides a telescopic rod adjustment mechanism, the telescopic rod adjustment mechanism comprising:

[0005] The inner tube and the outer tube sleeved on the outside of the inner tube are characterized in that:

[0006] The inner tube sidewall is provided with positioning holes;

[0007] A retaining spring component is coupled between the inner tube and the outer tube. The retaining spring component is fixed to different positioning holes on the inner tube for telescopic adjustment by rotating the outer tube relative to the inner tube.

[0008] As a further improvement of the present invention, a retaining ring limiting groove is provided inside the outer tube for fixing the retaining ring component.

[0009] As a further improvement of the present invention, the retaining spring component is bent inward in the middle to form a triangular support position, which facilitates the retaining spring component to be inserted into the positioning hole.

[0010] As a further improvement of the present invention, a spring is provided between the retaining ring and the outer tube to cooperate with the retaining ring component to rebound.

[0011] As a further improvement of the present invention, a spring limiting hole is provided inside the outer tube for fixing the spring.

[0012] As a further improvement of the present invention, a cover is installed on one end of the outer tube where the retaining ring and the spring are mounted, and a limiting groove is provided on the cover for fixing the retaining ring and the spring.

[0013] As a further improvement of the present invention, the outer tube is provided with a screw post, and the cover is provided with a screw through hole, so that the cover is fixed to the outer tube by the screw passing through the screw through hole and entering the screw post.

[0014] As a further improvement of the present invention, the positioning holes are symmetrically arranged along the diameter of the inner tube sidewall, and the snap ring components are symmetrically arranged about the center of the outer tube, thereby improving the stability of the connection between the outer tube and the inner tube.

[0015] This application also provides an electric fan, which includes the telescopic rod adjustment mechanism described above.

[0016] As a further improvement of the present invention, the telescopic rod adjustment mechanism is made of a rigid, low-density material, which can improve the overall stability of the electric fan.

[0017] The technical problem solved by this invention is:

[0018] Most existing telescopic poles are fixed with screws, which are exposed and extend a considerable distance, significantly impacting the overall appearance and resulting in a lower-quality look. Furthermore, existing screw-based telescopic structures are inconvenient to operate, requiring both hands and leading to a poor user experience.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention features a spring-loaded locking structure, with the spring designed inside the outer tube, eliminating any exposed components and enhancing the aesthetic appeal of the telescopic rod. The telescopic rod is adjusted via a reciprocating rotation, providing convenient operation and effectively improving the user experience. Attached Figure Description

[0059] Based on the problems existing in related technologies, this application provides a telescopic rod adjustment mechanism, which can solve the problems of poor user experience when adjusting the height of existing telescopic rods, requiring users to bend over with both hands, and the problem of exposed screws affecting the appearance and texture.

[0060] Example 1:

[0061] Reference Figure 2 The diagram shown illustrates a telescopic rod adjustment mechanism according to an embodiment of the present invention. The telescopic rod adjustment mechanism includes:

[0062] Inner tube 4 and outer tube 1 sleeved on the outside of the inner tube;

[0063] A positioning hole 41 is provided on the side wall of the inner tube;

[0064] A retaining ring 3 is coupled between the inner tube 4 and the outer tube 1. The retaining ring 3 is fixed to different positioning holes 41 on the inner tube 4 by rotating the outer tube 1 relative to the inner tube 4 for telescopic adjustment.

[0065] Reference Figure 3 The figure shown is an assembly diagram of a telescopic rod adjustment mechanism provided in an embodiment of the present invention, including: an outer tube 1, an inner tube 4, and a retaining spring 3.

[0066] Reference Figure 4 The diagram shows the assembly parts of a telescopic rod adjustment mechanism provided by the present invention. In this embodiment, the telescopic rod adjustment mechanism includes: an inner tube 4, a positioning hole 41, an outer tube 1, a retaining spring limiting groove 12, a retaining spring 3, a triangular support 31, and a limiting post 32.

[0067] In detail, during the assembly of the telescopic rod adjustment mechanism, the two retaining rings 3 are fixed inside the outer tube 1 through the retaining ring limiting groove 12. After the outer tube 1 is assembled, the positioning hole 41 on the inner tube 4 is aligned with the triangular support position 31 of the retaining ring 3, so that the retaining ring is inserted into the positioning hole 41, and the extension and retraction of the telescopic rod is restricted by fixing the position of the retaining ring 3.

[0068] Reference Figure 5 The figure shown is a cross-sectional view of a telescopic rod adjustment mechanism with the retaining spring 3 in its normal state, according to an embodiment of the present invention. The telescopic rod adjustment mechanism with the retaining spring 3 in its normal state includes:

[0069] Outer tube 1, snap ring limiting groove 12, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31;

[0070] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0071] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 corresponds to the position of the triangular support 31.

[0072] Reference Figure 6 The figure shown is a cross-sectional view of a telescopic rod adjustment mechanism with the retaining spring 3 in a retracted state, according to an embodiment of the present invention. The telescopic rod adjustment mechanism with the retaining spring 3 in a retracted state includes:

[0073] Outer tube 1, snap ring limiting groove 12, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31;

[0074] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0075] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 is offset from that of the triangular support 31.

[0076] Working principle:

[0077] When the triangular support is engaged in the positioning hole 41, the retaining spring 3 is in its normal state. When the user needs to adjust the telescopic rod, the outer tube 1 rotates relative to the inner tube 4. The triangular support 31 on the retaining spring 3 is squeezed by the positioning hole 41. Since the outer tube 1 fixes the limiting post 32 through the retaining spring limiting groove 12, thereby fixing the retaining spring 3, the retaining spring 3 is compressed and contracts, and the retaining spring 3 is in a contracted state.

[0078] Furthermore, when the retaining spring 3 is in the retracted state, the telescopic rod is adjusted to a suitable height, causing the outer tube 1 to rotate in the opposite direction to the inner tube 4. When the triangular support 31 coincides with the positioning hole 41, the retaining spring 3 springs back, the triangular support 31 re-engages into the positioning hole, and the retaining spring 3 returns to its normal state, completing the telescopic rod adjustment.

[0079] In this embodiment of the invention, by using the retaining spring 3 to lock the adjustment mechanism of the positioning hole 41 on the inner tube 4, the user can adjust the telescopic rod without bending over, which improves the user experience. In addition, the retaining spring 3 is set inside the outer tube 1, which enhances the appearance and texture of the telescopic rod.

[0080] Example 2:

[0081] Since the telescopic rod is adjusted by only pressing the retaining spring 3 and its own elasticity during use, the retaining spring 3 is prone to deformation or even breakage after repeated use.

[0082] Reference Figure 7 As shown in the figure, a cross-sectional view of a telescopic rod adjustment mechanism with a spring is provided in an embodiment of the present invention. The telescopic rod adjustment mechanism with a spring includes:

[0083] Inner tube 4 and outer tube 1 sleeved on the outside of the inner tube;

[0084] The inner tube 4 has a positioning hole 41 on its side wall;

[0085] A retaining ring 3 and a spring 2 are coupled between the inner tube 4 and the outer tube 1. The retaining ring 3 is fixed to different positioning holes 41 on the inner tube 4 by rotating the outer tube 1 relative to the inner tube 4 for telescopic adjustment.

[0086] Reference Figure 8 The figure shown is an assembly diagram of a telescopic rod adjustment mechanism with a spring provided in an embodiment of the present invention, including: an outer tube 1, an inner tube 4, a retaining ring 3, and a spring 2.

[0087] Reference Figure 9 The diagram shows an assembly of a spring-loaded telescopic rod adjustment mechanism according to the present invention. In this embodiment, the spring-loaded telescopic rod adjustment mechanism includes: an inner tube 4, a positioning hole 41, an outer tube 1, a retaining ring limiting groove 12, a spring limiting hole 13, a retaining ring 3, a triangular support 31, a limiting post 32, and a spring 2.

[0088] In detail, during assembly, the spring-loaded telescopic rod adjustment mechanism is assembled by fixing two retaining rings 3 inside the outer tube 1 through the retaining ring limiting groove 12, and fixing two springs 2 between the retaining rings 3 and the inner wall of the outer tube 1 through the spring limiting hole. After the outer tube 1 is assembled, the positioning hole 41 on the inner tube 4 is aligned with the triangular support position 31 of the retaining ring 3, so that the retaining ring is engaged in the positioning hole 41, thereby limiting the extension and retraction of the telescopic rod by fixing the position of the retaining ring 3.

[0089] Reference Figure 10 The diagram shows a cross-sectional view of a spring-loaded telescopic rod adjustment mechanism with the retaining ring 3 in its normal state, according to an embodiment of the present invention. The spring-loaded telescopic rod adjustment mechanism with the retaining ring 3 in its normal state includes:

[0090] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0091] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0092] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0093] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 corresponds to the position of the triangular support 31.

[0094] Reference Figure 11 The diagram shows a cross-sectional view of a spring-loaded telescopic rod adjustment mechanism assembly with the retaining spring 3 in a retracted state, according to an embodiment of the present invention. The spring-loaded telescopic rod adjustment mechanism assembly with the retaining spring 3 in a retracted state includes:

[0095] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0096] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0097] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0098] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 is offset from that of the triangular support 31.

[0099] Working principle:

[0100] When the triangular support 31 is engaged in the positioning hole 41, the retaining spring 3 and the spring 2 are in their normal state. When the user needs to adjust the telescopic rod, the outer tube 1 rotates relative to the inner tube 4. The triangular support 31 on the retaining spring 3 is squeezed by the positioning hole 41. Since the outer tube 1 fixes the limiting post 32 through the retaining spring limiting groove 12, thereby fixing the retaining spring 3, the retaining spring 3 is compressed and contracts. The retaining spring 3 is in a contracted state, and the spring 2 is in a compressed state.

[0101] Furthermore, when the retaining ring 3 is in the retracted state and the spring 2 is in the compressed state, adjust the telescopic rod to a suitable height so that the outer tube 1 rotates in the opposite direction to the inner tube 4. When the triangular support 31 coincides with the positioning hole 41, the spring 2, together with the retaining ring 3, rebounds, and the triangular support 31 re-engages into the positioning hole 41. The retaining ring 3 and the spring 2 return to their normal state, completing the telescopic rod adjustment.

[0102] In this embodiment of the invention, by using the retaining spring 3 to lock the adjustment mechanism of the positioning hole 41 on the inner tube 4, the user can adjust the telescopic rod without bending over, improving the user experience. Furthermore, the retaining spring 3, located inside the outer tube 1, enhances the appearance and texture of the telescopic rod. By adding the spring 2 between the retaining spring 3 and the inner wall of the outer tube, the spring 2 can cooperate with the retaining spring 3 to rebound, increasing the rebound speed of the retaining spring 3 and extending its service life.

[0103] Example 3:

[0104] When the outer tube 1 rotates relative to the inner tube 4, the retaining ring 3 is compressed and in a contracted state, and the spring 2 is in a compressed state. At this time, the spring 2 and the retaining ring 3 have elastic potential energy. It is not stable to fix the spring 2 and the retaining ring 3 only through the spring limiting hole 13 and the retaining ring limiting groove 12 on the outer tube 1. The spring 2 and the retaining ring 3 may pop out from the outer tube 1, causing a safety problem.

[0105] Reference Figure 12 As shown in the figure, an embodiment of the present invention provides a schematic diagram of a telescopic rod adjustment mechanism with a cover, the telescopic rod adjustment mechanism comprising:

[0106] Inner tube 4 and outer tube 1 sleeved on the outside of the inner tube, cover 5;

[0107] A positioning hole 41 is provided on the side wall of the inner tube 1;

[0108] A retaining ring 3 and a spring 2 are coupled between the inner tube 4 and the outer tube 1. The retaining ring 3 is fixed to different positioning holes 41 on the inner tube 4 by rotating the outer tube 1 relative to the inner tube 4 for telescopic adjustment.

[0109] The cover 5 is provided with a limiting groove 52;

[0110] The cover 5 is installed on one end of the outer tube 1 where the retaining ring 3 and the spring 2 are fixed;

[0111] The cover 5 fixes the spring 2 and the retaining ring 3 through the limiting groove 52.

[0112] Reference Figure 13 The figure shown is an assembly diagram of a telescopic rod adjustment mechanism with a cover provided in an embodiment of the present invention, including: an outer tube 1, an inner tube 4, a retaining ring 3, a spring 2, and a cover 5.

[0113] Reference Figure 14The diagram shows an assembly of a telescopic rod adjustment mechanism with a cover provided by the present invention. In this embodiment, the telescopic rod adjustment mechanism includes: an inner tube 4, a positioning hole 41, an outer tube 1, a screw post 11, a retaining spring limiting groove 12, a spring limiting hole 13, a retaining spring 3, a triangular support 31, a limiting post 32, a spring 2, a cover 5, a screw through hole 51, and a limiting groove 52.

[0114] In detail, during assembly, the telescopic rod adjustment mechanism with a cover involves fixing two retaining rings 3 inside the outer tube 1 via the retaining ring limiting groove 12, fixing two springs 2 between the retaining rings 3 and the inner wall of the outer tube 1 via the spring limiting hole, aligning the limiting groove 52 on the cover 5 with the positions of the spring limiting hole 13 and the retaining ring limiting groove, and fixing the cover 5 to the outer tube 1 by screw engagement through the screw post 11 and the screw through hole 51. After the outer tube 1 is assembled, align the positioning hole 41 on the inner tube 4 with the triangular support position 31 of the retaining ring 3, so that the retaining ring is engaged in the positioning hole 41, thereby restricting the extension and retraction of the telescopic rod by fixing the position of the retaining ring 3.

[0115] Reference Figure 15 The diagram shows a cross-sectional view of a telescopic rod adjustment mechanism with a spring in the normal state of the retaining spring 3, and a telescopic rod adjustment mechanism with a cover in the retracted state of the retaining spring 3, comprising:

[0116] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0117] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0118] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0119] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 corresponds to the position of the triangular support 31.

[0120] Reference Figure 16 The diagram shows a cross-sectional view of a telescopic rod adjustment mechanism assembly with a spring in the retracted state, provided by an embodiment of the present invention. The telescopic rod adjustment mechanism assembly with a cover in the retracted state includes:

[0121] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0122] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0123] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0124] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 is offset from that of the triangular support 31.

[0125] Working principle:

[0126] When the triangular support 31 is engaged in the positioning hole 41, the retaining spring 3 and the spring 2 are in their normal state. When the user needs to adjust the telescopic rod, the outer tube 1 rotates relative to the inner tube 4. The triangular support 31 on the retaining spring 3 is squeezed by the positioning hole 41. Since the outer tube 1 fixes the limiting post 32 through the retaining spring limiting groove 12, thereby fixing the retaining spring 3, the retaining spring 3 is compressed and contracts. The retaining spring 3 is in a contracted state, and the spring 2 is in a compressed state.

[0127] Furthermore, when the retaining ring 3 is in the retracted state and the spring 2 is in the compressed state, the telescopic rod is adjusted to a suitable height, causing the outer tube 1 to rotate in the opposite direction to the inner tube 4. The spring 2, together with the retaining ring 3, rebounds, and the triangular support 31 re-engages into the positioning hole 41. The retaining ring 3 and the spring 2 return to their normal state, completing the telescopic rod adjustment.

[0128] In this embodiment of the invention, by using the retaining spring 3 to lock the adjustment mechanism of the positioning hole 41 on the inner tube 4, the user can adjust the telescopic rod without bending over, improving the user experience. Furthermore, the retaining spring 3, located inside the outer tube 1, enhances the appearance and texture of the telescopic rod. By adding the spring 2 between the retaining spring 3 and the inner wall of the outer tube, the spring 2 can cooperate with the retaining spring 3 to rebound, increasing the rebound speed of the retaining spring 3 and extending its service life. By installing the cover 5 at the end of the outer tube where the spring 2 and the retaining spring 3 are fixed, the outer tube 1, together with the spring 2 and the retaining spring 3, fixes the spring 2 and the retaining spring 3, increasing the stability of the spring 2 and the retaining spring 2 under compressed conditions and improving safety.

[0131] For details, refer to Figure 1 The diagram shown is a schematic representation of an electric fan with a telescopic rod adjustment mechanism according to an embodiment of the present invention. In this embodiment, the electric fan includes: a fan head 6, an outer tube 1, an inner tube 4, and a base 7.

[0132] Reference Figure 2 The diagram shown illustrates a telescopic rod adjustment mechanism according to an embodiment of the present invention. The telescopic rod adjustment mechanism includes:

[0133] Inner tube 4 and outer tube 1 sleeved on the outside of the inner tube;

[0134] A positioning hole 41 is provided on the side wall of the inner tube;

[0135] A retaining ring 3 is coupled between the inner tube 4 and the outer tube 1. The retaining ring 3 is fixed to different positioning holes 41 on the inner tube 4 by rotating the outer tube 1 relative to the inner tube 4 for telescopic adjustment.

[0136] In this embodiment of the invention, the telescopic rod adjustment mechanism is made of a rigid, low-density material (such as aluminum alloy, iron-aluminum alloy, stainless steel, etc.), which can improve the overall stability of the electric fan.

[0137] In detail, the telescopic rod adjustment mechanism is made of a rigid, low-density material, which can improve the stability of the connection of the telescopic rod adjustment mechanism, while lowering the center of gravity of the electric fan, thereby improving the overall standing stability of the electric fan.

[0138] Reference Figure 3 The figure shown is an assembly diagram of a telescopic rod adjustment mechanism provided in an embodiment of the present invention, including: an outer tube 1, an inner tube 4, and a retaining spring 3.

[0139] Reference Figure 4 The diagram shows the assembly parts of a telescopic rod adjustment mechanism provided by the present invention. In this embodiment, the telescopic rod adjustment mechanism includes: an inner tube 4, a positioning hole 41, an outer tube 1, a retaining spring limiting groove 12, a retaining spring 3, a triangular support 31, and a limiting post 32.

[0140] In detail, during the assembly of the telescopic rod adjustment mechanism, the two retaining rings 3 are fixed inside the outer tube 1 through the retaining ring limiting groove 12. After the outer tube 1 is assembled, the positioning hole 41 on the inner tube 4 is aligned with the triangular support position 31 of the retaining ring 3, so that the retaining ring is inserted into the positioning hole 41, and the extension and retraction of the telescopic rod is restricted by fixing the position of the retaining ring 3.

[0141] Reference Figure 5 The figure shown is a cross-sectional view of a telescopic rod adjustment mechanism with the retaining spring 3 in its normal state, according to an embodiment of the present invention. The telescopic rod adjustment mechanism with the retaining spring 3 in its normal state includes:

[0142] Outer tube 1, snap ring limiting groove 12, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31;

[0143] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0144] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 corresponds to the position of the triangular support 31.

[0145] Reference Figure 6 The figure shown is a cross-sectional view of a telescopic rod adjustment mechanism with the retaining spring 3 in a retracted state, according to an embodiment of the present invention. The telescopic rod adjustment mechanism with the retaining spring 3 in a retracted state includes:

[0146] Outer tube 1, snap ring limiting groove 12, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31;

[0147] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0148] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 is offset from that of the triangular support 31.

[0149] Working principle:

[0150] When the triangular support is engaged in the positioning hole 41, the retaining spring 3 is in its normal state. When the user needs to adjust the telescopic rod, the outer tube 1 rotates relative to the inner tube 4. The triangular support 31 on the retaining spring 3 is squeezed by the positioning hole 41. Since the outer tube 1 fixes the limiting post 32 through the retaining spring limiting groove 12, thereby fixing the retaining spring 3, the retaining spring 3 is compressed and contracts, and the retaining spring 3 is in a contracted state.

[0151] Furthermore, when the retaining spring 3 is in the retracted state, the fan head 6 is manually adjusted to a suitable height, causing the outer tube 1 to rotate in the opposite direction to the inner tube 4. When the triangular support 31 coincides with the positioning hole 41, the retaining spring 3 springs back, the triangular support 31 re-engages into the positioning hole, and the retaining spring 3 returns to its normal state, completing the telescopic rod adjustment.

[0152] In this embodiment of the invention, by using the retaining spring 3 to lock the adjustment mechanism of the positioning hole 41 on the inner tube 4, the user can adjust the height of the fan without bending over, which improves the user experience when adjusting the height of the fan. In addition, the retaining spring 3 is set inside the outer tube 1, which enhances the appearance and integrity of the electric fan.

[0153] Since the telescopic rod is adjusted by only pressing the retaining spring 3 and its own elasticity during use, the retaining spring 3 is prone to deformation or even breakage after repeated use.

[0155] Inner tube 4 and outer tube 1 sleeved on the outside of the inner tube;

[0156] The inner tube 4 has a positioning hole 41 on its side wall;

[0157] A retaining ring 3 and a spring 2 are coupled between the inner tube 4 and the outer tube 1. The retaining ring 3 is fixed to different positioning holes 41 on the inner tube 4 by rotating the outer tube 1 relative to the inner tube 4 for telescopic adjustment.

[0158] Reference Figure 8 The figure shown is an assembly diagram of a telescopic rod adjustment mechanism with a spring provided in an embodiment of the present invention, including: an outer tube 1, an inner tube 4, a retaining ring 3, and a spring 2.

[0159] Reference Figure 9 The diagram shows an assembly of a spring-loaded telescopic rod adjustment mechanism according to the present invention. In this embodiment, the spring-loaded telescopic rod adjustment mechanism includes: an inner tube 4, a positioning hole 41, an outer tube 1, a retaining ring limiting groove 12, a spring limiting hole 13, a retaining ring 3, a triangular support 31, a limiting post 32, and a spring 2.

[0160] In detail, during assembly, the spring-loaded telescopic rod adjustment mechanism is assembled by fixing two retaining rings 3 inside the outer tube 1 through the retaining ring limiting groove 12, and fixing two springs 2 between the retaining rings 3 and the inner wall of the outer tube 1 through the spring limiting hole. After the outer tube 1 is assembled, the positioning hole 41 on the inner tube 4 is aligned with the triangular support position 31 of the retaining ring 3, so that the retaining ring is engaged in the positioning hole 41, thereby limiting the extension and retraction of the telescopic rod by fixing the position of the retaining ring 3.

[0161] Reference Figure 10The diagram shows a cross-sectional view of a spring-loaded telescopic rod adjustment mechanism with the retaining ring 3 in its normal state, according to an embodiment of the present invention. The spring-loaded telescopic rod adjustment mechanism with the retaining ring 3 in its normal state includes:

[0162] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0163] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0164] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0165] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 corresponds to the position of the triangular support 31.

[0166] Reference Figure 11 The diagram shows a cross-sectional view of a spring-loaded telescopic rod adjustment mechanism assembly with the retaining spring 3 in a retracted state, according to an embodiment of the present invention. The spring-loaded telescopic rod adjustment mechanism assembly with the retaining spring 3 in a retracted state includes:

[0167] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0168] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0169] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0170] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 is offset from that of the triangular support 31.

[0171] Working principle:

[0172] When the triangular support 31 is engaged in the positioning hole 41, the retaining spring 3 and the spring 2 are in their normal state. When the user needs to adjust the telescopic rod, the outer tube 1 rotates relative to the inner tube 4. The triangular support 31 on the retaining spring 3 is squeezed by the positioning hole 41. Since the outer tube 1 fixes the limiting post 32 through the retaining spring limiting groove 12, thereby fixing the retaining spring 3, the retaining spring 3 is compressed and contracts. The retaining spring 3 is in a contracted state, and the spring 2 is in a compressed state.

[0173] Furthermore, when the retaining ring 3 is in the retracted state and the spring 2 is in the compressed state, the height of the fan head 6 is adjusted by hand, causing the outer tube 1 to rotate in the opposite direction to the inner tube 4. When the triangular support 31 coincides with the positioning hole 41, the spring 2 and the retaining ring 3 rebound, and the triangular support 31 re-engages into the positioning hole 41. The retaining ring 3 and the spring 2 return to their normal state, completing the adjustment of the telescopic rod.

[0174] In this embodiment of the invention, by using the retaining spring 3 to lock the adjustment mechanism of the positioning hole 41 on the inner tube 4, the user can adjust the fan height without bending over, improving the user experience when adjusting the fan height. Furthermore, the retaining spring 3, located inside the outer tube 1, enhances the overall aesthetic appearance of the electric fan. By adding the spring 2 between the retaining spring 3 and the inner wall of the outer tube, the spring 2 can cooperate with the retaining spring 3 to rebound, increasing the rebound speed of the retaining spring 3 and extending its service life.

[0175] When the outer tube 1 rotates relative to the inner tube 4, the retaining ring 3 is compressed and in a contracted state, and the spring 2 is in a compressed state. At this time, the spring 2 and the retaining ring 3 have elastic potential energy. It is not stable to fix the spring 2 and the retaining ring 3 only through the spring limiting hole 13 and the retaining ring limiting groove 12 on the outer tube 1. The spring 2 and the retaining ring 3 may pop out from the outer tube 1, causing a safety problem.

[0177] Inner tube 4 and outer tube 1 sleeved on the outside of the inner tube, cover 5;

[0178] A positioning hole 41 is provided on the side wall of the inner tube 1;

[0179] A retaining ring 3 and a spring 2 are coupled between the inner tube 4 and the outer tube 1. The retaining ring 3 is fixed to different positioning holes 41 on the inner tube 4 by rotating the outer tube 1 relative to the inner tube 4 for telescopic adjustment.

[0180] The cover 5 is provided with a limiting groove 52;

[0181] The cover 5 is installed on one end of the outer tube 1 where the retaining ring 3 and the spring 2 are fixed;

[0182] The cover 5 secures the spring 2 and the retaining ring 3 together through the limiting groove 52.

[0183] Reference Figure 13 The figure shown is an assembly diagram of a telescopic rod adjustment mechanism with a cover provided in an embodiment of the present invention, including: an outer tube 1, an inner tube 4, a retaining ring 3, a spring 2, and a cover 5.

[0184] Reference Figure 14 The diagram shows an assembly of a telescopic rod adjustment mechanism with a cover provided by the present invention. In this embodiment, the telescopic rod adjustment mechanism includes: an inner tube 4, a positioning hole 41, an outer tube 1, a screw post 11, a retaining spring limiting groove 12, a spring limiting hole 13, a retaining spring 3, a triangular support 31, a limiting post 32, a spring 2, a cover 5, a screw through hole 51, and a limiting groove 52.

[0185] In detail, during assembly, the telescopic rod adjustment mechanism with a cover involves fixing two retaining rings 3 inside the outer tube 1 via the retaining ring limiting groove 12, fixing two springs 2 between the retaining rings 3 and the inner wall of the outer tube 1 via the spring limiting hole, aligning the limiting groove 52 on the cover 5 with the positions of the spring limiting hole 13 and the retaining ring limiting groove, and fixing the cover 5 to the outer tube 1 by screw engagement through the screw post 11 and the screw through hole 51. After the outer tube 1 is assembled, align the positioning hole 41 on the inner tube 4 with the triangular support position 31 of the retaining ring 3, so that the retaining ring is engaged in the positioning hole 41, thereby restricting the extension and retraction of the telescopic rod by fixing the position of the retaining ring 3.

[0186] Reference Figure 15 The diagram shows a cross-sectional view of a telescopic rod adjustment mechanism with a spring in the normal state of the retaining spring 3, and a telescopic rod adjustment mechanism with a cover in the retracted state of the retaining spring 3, comprising:

[0187] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0188] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0189] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0190] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 corresponds to the position of the triangular support 31.

[0191] Reference Figure 16The diagram shows a cross-sectional view of a telescopic rod adjustment mechanism assembly with a spring in the retracted state, provided by an embodiment of the present invention. The telescopic rod adjustment mechanism assembly with a cover in the retracted state includes:

[0192] Outer tube 1, snap ring limiting groove 12, spring limiting hole 13, inner tube 4, positioning hole 41, snap ring 3, limiting post 32, triangular support position 31, spring 2;

[0193] Two retaining rings 3 are installed inside the outer tube 1. The outer tube 1 fixes the retaining post 32 by means of the retaining ring limiting groove 12, thereby fixing the retaining rings 3.

[0194] The spring 2 is fixed between the snap ring 3 and the inner wall of the outer tube 1 through the spring limiting hole 13;

[0195] The inner tube 4 is located inside the outer tube 1, and the position of the positioning hole 41 is offset from that of the triangular support 31.

[0196] Working principle:

[0197] When the triangular support 31 is engaged in the positioning hole 41, the retaining spring 3 and the spring 2 are in their normal state. When the user needs to adjust the telescopic rod, the outer tube 1 rotates relative to the inner tube 4. The triangular support 31 on the retaining spring 3 is squeezed by the positioning hole 41. Since the outer tube 1 fixes the limiting post 32 through the retaining spring limiting groove 12, thereby fixing the retaining spring 3, the retaining spring 3 is compressed and contracts. The retaining spring 3 is in a contracted state, and the spring 2 is in a compressed state.

[0198] Furthermore, when the retaining ring 3 is in the retracted state and the spring 2 is in the compressed state, the height of the fan head 6 is adjusted by hand, causing the outer tube 1 to rotate in the opposite direction to the inner tube 4. The spring 2, together with the retaining ring 3, rebounds, and the triangular support 31 re-engages into the positioning hole 41. The retaining ring 3 and the spring 2 return to their normal state, completing the adjustment of the telescopic rod.

[0199] In this embodiment of the invention, by using the retaining spring 3 to lock the adjustment mechanism of the positioning hole 41 on the inner tube 4, the user can adjust the fan height without bending over, improving the user experience when adjusting the fan height. Furthermore, the retaining spring 3, located inside the outer tube 1, enhances the overall appearance of the electric fan. By adding the spring 2 between the retaining spring 3 and the inner wall of the outer tube, the spring 2 can cooperate with the retaining spring 3 to rebound, increasing the rebound speed of the retaining spring 3 and extending its service life. By installing the cover 5 at the end of the outer tube where the spring 2 and the retaining spring 3 are fixed, the outer tube 1, together with the spring 2 and the retaining spring 3, fixes the spring 2 and the retaining spring 3, increasing the stability of the spring 2 and the retaining spring 2 under compressed conditions and improving safety.
