Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an adjustable telescopic rod, a horizontal handle and a vehicle. Background Art

[0002] As a means of transportation, scooters are energy-saving, environmentally friendly, lightweight and compact. They are becoming increasingly popular among people of all ages and are widely used in urban transportation.

[0003] Reference patent document CN00263396.5 proposes a folding structure of a scooter handlebar, which mentions: "The utility model mainly comprises a frame, a sleeve is provided above the frame, a through hole is passed through the two ends of the sleeve, and embedding holes are provided above the two ends of the through hole, the bottom of the sleeve is set as a flat surface, and a groove is cut at the two ends of the flat surface; two handles are respectively set in the through holes at the two ends of the sleeve, and the two handles are provided with fixing parts at the opposite ends, and an elastic rope passing through the two ends of the through hole of the sleeve is connected between the two fixing parts, and an elastically retractable embedding column is provided above the two fixing parts", "During assembly, the fixing parts of the two handles are set into the through holes at the two ends of the sleeve, so that the embedding columns of the fixing parts of the two handles can be embedded in the embedding holes at the two ends of the sleeve, and the two handles are firmly embedded in the through holes of the sleeve by the elastic tension of the elastic rope between the two handles".

[0004] In the prior art, the handle is provided at one end of the fixing portion, the fixing portion is retractable in the through hole, and the fixing portion and the sleeve are relatively fixed by inserting an elastically retractable embedded column on the fixing portion into the embedded hole above the through hole, so that the fixing portion and the sleeve are relatively fixed, and the handle is fixedly installed on the sleeve; however, in the actual use of the scooter, it is often necessary to meet the needs of various different groups of people, such as children and adults, and there are differences in arm lengths between different individuals; in the prior art, after the handle is installed on the sleeve through the fixing portion, the position of the fixing portion and the sleeve is not adjustable, so that the distance between the two handles is not adjustable. Therefore, it can be seen that the horizontal handle structure in the prior art cannot adjust the length of the horizontal handle according to individual differences because there are no multiple fixing mechanisms between the fixing portion and the sleeve.

[0005] Therefore, the disadvantage of the prior art is that there is a technical problem of how to set multiple fixing positions between the fixing part and the sleeve in the direction in which the fixing part is retractable relative to the sleeve. Summary of the invention

[0020] When the screw is at the first end of the through hole, the second groove is connected to the first groove, and any rib can move from the first groove to the second groove, or from the second groove to the first groove;

[0021] When the position of the screw relative to the through hole changes from the first end to the second end, the second groove and the first groove change from a connected state to a disconnected state.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limitations on the present invention. Example 1

[0042] like Figure 1-2 As shown, the present invention proposes an adjustable telescopic rod, comprising a first component 1 and a rod body 3, wherein the first component 1 is sleeved on the rod body 3, and the first component 1 is used to fix the rod body 3 in radial and circumferential directions; the second component 2 and the first component 1 form a connection structure that is inseparable in the axial and radial directions and can rotate coaxially, and an annular protrusion 205 is arranged on the second component 2, and one end of the first component 1 abuts against the end surface of one end of the annular protrusion 205; a plurality of fixing positions 303 are arranged on the rod body 3, and the plurality of fixing positions 303 are arranged in sequence along the axial direction of the rod body 3, and any fixing position 303 can be accommodated in the second component 2; when the annular protrusion 205 is inserted into the fixing position 303, the second component 2 and the rod body 3 are in a fixed state along the axial direction; when the annular protrusion 205 is disengaged from the fixing position 303, the second component 2 and the rod body 3 are in a non-fixed state along the axial direction.

[0043] The adjustable telescopic rod proposed in this embodiment is actually a telescopic structure composed of a first component 1 and a rod body 3 , and the second component 2 is actually used to connect and lock the first component 1 and the rod body 3 .

[0044] The first component 1 is configured to be tubular, wherein the first component 1 can accommodate the rod body 3 along the axial direction; specifically, at least one end of the first component 1 is provided with a tube hole, and one end of the rod body 3 can be inserted into the tube hole; the rod body 3 inserted into the tube hole can slide in the tube cavity of the first component 1, wherein a gap connection is formed between the rod body 3 and the inner wall of the tube cavity; thus, the rod body 3 and the first component 1 form a telescopic structure.

[0045] The second component 2 is configured to be tubular, and the second component 2 is sleeved on the first component 1 , and the second component 2 can be penetrated by the rod body 3 .

[0046] Specifically, Figure 2 , Figure 4 , an annular protrusion 205 is provided inside the second component 2, and the axis of the annular protrusion 205 is coaxial with the axis of the second component 2. The annular protrusion 205 and the second component 2 can form a detachable connection or a non-detachable connection; for example, a threaded hole is provided on the annular protrusion 205, and a through hole is provided on the wall of the second component 2, and a screw passes through the through hole on the wall of the second component 2 and is threadedly connected with the threaded hole of the annular protrusion 205, so that the second component 2 and the annular protrusion 205 form a detachable connection structure; for example, the second component 2 and the annular protrusion 205 are an integrally processed structure, and the annular protrusion 205 extends integrally from the inner wall of the second component 2 toward the axis direction of the second component 2, that is, the annular protrusion 205 and the second component 2 form a non-detachable connection structure.

[0047] The annular protrusion 205 can be arranged at one of the axial ends of the second component 2, or the annular protrusion 205 can be arranged between the axial ends of the second component 2; the annular protrusion 205 can be penetrated by the rod body 3, wherein the second component 2 can be penetrated by the rod body 3, and the annular protrusion 205 is also penetrated by the rod body 3, and when the rod body 3 penetrates the annular protrusion 205, a gap connection state is formed between the rod body 3 and the annular protrusion 205; the first component 1 cannot penetrate the annular protrusion 205, wherein, when the first component 1 is inserted into the second component 2, the first component 1 contacts or does not contact one of the end faces of the annular protrusion 205.

[0048] Preferably, the annular protrusion 205 is configured to be a straight tubular structure, and the inner wall diameter of the annular protrusion 205 is smaller than the inner wall diameter of the second component 2. The second component 2 and the annular protrusion 205 are integrally formed, and the annular protrusion 205 is formed by extending the inner wall of the second component 2 toward the axial direction of the second component 2; when the first component 1 is inserted into the second component 2, the first component 1 abuts against one of the end faces of the annular protrusion 205.

[0049] The rod body 3 is a linear rod-shaped structure. Preferably, a through channel is provided in the rod body 3 to remove part of the mass in the rod body 3 so as to reduce the weight of the rod body 3. At the same time, the overall weight of the adjustable telescopic rod is also reduced, which is convenient for taking, transporting and installing.

[0050] The first component 1 and the second component 2 form an axially and radially inseparable and coaxially rotatable connection structure; specifically, the second component 2 is sleeved on the circumferential outer surface of the first component 1, and the inner wall of the second component 2 and the circumferential surface of the first component 1 are clearance-matched, so that the second component 2 can be coaxially rotatable relative to the first component 1, and the circumferential outer surface of the first component 1 forms a radial restriction on the inner wall of the second component 2, so that the second component 2 cannot move radially; an axially inseparable structure is also formed between the first component 1 and the second component 2, for example: a connecting ring is provided on the inner wall of the second component 2, and a clamping groove is provided on the outer wall of the first component 1, and after the connecting ring is clamped into the clamping groove, an axially inseparable connection structure is formed between the second component and the first component; for another example: the second component 2 is provided with a connecting groove, and the connecting groove is set as a through hole, and a threaded hole is provided on the circumferential surface of the first component 1. When the second component 2 is sleeved on the first component 1, the axially inseparable connection structure between the second component 2 and the first component 1 can be achieved by simultaneously penetrating the connecting groove and the threaded hole with a screw.

[0051] The first component 1 is sleeved on the rod body 3, and a radial fixing structure can be formed between the first component 1 and the rod body 3; specifically, one end of the rod body 3 is inserted into the tube hole of the first component 1, and the inner wall of the first component 1 forms a gap connection with the circumferential outer wall of the rod body 3. The inner wall of the first component 1 limits the radial movement of the rod body 3, that is, the gap connection formed by the circumferential outer surface of the rod body 3 and the inner wall of the first component 1 is the radial fixing structure.

[0052] like Figure 2 , Figure 3 A circumferential fixed structure can also be formed between the first component 1 and the rod body 3. Specifically, a first groove 102 is provided on the first component 1, and the first groove 102 penetrates the first component 1 along the axial direction of the first component 1. It is worth noting that in order to facilitate the processing of the first groove 102 on the inner wall of the first component 1, the first component 1 should be set as a straight tubular structure; since the first component 1 is a straight tubular structure, in order to allow the rod body 3 to freely expand and contract in the first component 1, the rod body 3 is set as a rod-shaped structure extending along a straight line; a plurality of convex ribs 301 are arranged at intervals on the outer surface of the rod body 3, and any convex rib 301 is provided at intervals. The extension direction of the rib 301 is parallel to the axial direction of the rod body 3. When the rod body 3 is inserted into the first component 1 from the opening at one end of the first component 1 along the axial direction, the rod body 3 drives the convex rib 301 to be inserted into the first groove 102. The groove wall of the first groove 102 forms a restriction on the convex rib 301 along the circumferential direction of the rod body 3; and the convex rib 301 is connected to the rod body 3, so that the rod body 3 is fixed relative to the first component 1 along the circumferential direction; that is, a circumferential direction fixing structure is formed between the rod body 3 and the first component 1, and the circumferential direction fixing structure makes the rod body 3 non-rotatable relative to the first component in the circumferential direction.

[0053] The connection structure between the rod body 3 and the second component 2 is achieved by the following scheme: a plurality of fixing positions 303 are arranged on the outer surface of the rod body 3, and the plurality of fixing positions 303 are arranged in sequence along the axial direction of the rod body 3. The fixing positions 303 are in the shape of grooves, and the concave direction of the grooves points to the axial center line of the rod body 3. The annular protrusion 205 can be selectively inserted into one of the plurality of fixing positions 303, and a fixed state and a non-fixed state can be formed between the annular protrusion 205 and any fixing position 303. When the annular protrusion forms a fixed state with the fixing position, the annular protrusion 205 is inserted into the fixing position 303 and forms a snap fit with the fixing position 303. When the annular protrusion 205 forms a non-fixed state with the fixing position 303, the annular protrusion 205 is arranged outside the fixing position 303. When the annular protrusion 205 is inserted into the fixing position 303 and axially engages with the fixing position 303, the annular protrusion 205 and the fixing position 303 are in a fixed state, and the rod body 3 cannot move relative to the second component 2; when the annular protrusion 205 is set outside the fixing position 303, the annular protrusion 205 and the fixing position 303 form a non-fixed state, and the rod body 3 can move axially relative to the second component 2.

[0054] Formation of the fixing position 303: As mentioned above, a plurality of ribs 301 are arranged at intervals on the outer surface of the rod body 3, and a fixing position 303 is formed between any two adjacent ribs 301; in other words, when the rod body 3 is processed, a strip ridge extending along the axial direction of the rod body 3 is processed on the outer surface of the rod body 3, and a plurality of grooves are processed on the strip ridge along the axial direction of the rod body 3. Then, the groove is the aforementioned fixing position 303, and a plurality of ribs 301 are formed by removing the groove from the strip ridge.

[0055] Optionally, multiple grooves are processed on the strip ridges at equal intervals along the axial direction of the rod body 3, or multiple grooves are processed on the strip ridges at unequal intervals along the axial direction of the rod body 3. When multiple grooves are processed on the strip ridges at equal intervals, the distance between each two adjacent fixed positions 303 is equal, which results in the same distance that the rod body 3 moves in the axial direction when switching from one fixed position to the next fixed position between the rod body 3 and the first component 1; when multiple grooves are processed on the strip ridges at unequal intervals, the distance between each two adjacent fixed positions 303 is unequal, which results in different distances that the rod body 3 moves in the axial direction when switching from one fixed position to the next fixed position between the rod body 3 and the first component 1. However, regardless of whether the distance that the rod body 3 moves in the axial direction is the same when switching from one fixed position to the next fixed position between the rod body 3 and the first component 1, the adjustable telescopic rod can achieve axial length adjustment.

[0056] In summary, the rod body 3 has three movable directions: axial, circumferential, and radial; the first component 1 is sleeved on the rod body 3, and the first component 1 limits the movement of the rod body 3 in the circumferential and radial directions. At this time, the rod body 3 can only move axially relative to the first component 1, that is, the rod body 3 is retractable relative to the first component 1; the second component 2 is coaxially rotatably sleeved on the first component 1. During the process of the rod body 3 being retractable relative to the first component 1, the second component 2 and the rod body 3 can be in a fixed state or a non-fixed state along the axial direction. When the second component 2 and the rod body 3 are in a non-fixed state along the axial direction, the axial direction of the rod body 3 is not restricted, and the rod body 3 is still retractable relative to the first component 1. When the second component 2 and the rod body 3 are in a fixed state along the axial direction, the axial movement of the rod body 3 is restricted by the second component 2. Combined with the above, at this time, the movement of the rod body 3 in the axial, circumferential, and radial directions is restricted, and the rod body 3 is immovable relative to the first component 1 and the second component 2.

[0057] When the adjustable telescopic rod is in use, the second component 2 and the rod body 3 are in a fixed state along the axial direction. When the length of the adjustable telescopic rod needs to be adjusted, the second component 2 is rotated around the axis of the second component 2 so that the annular protrusion 205 is disengaged from the fixed position 303, and the second component 2 and the rod body 3 are in a non-fixed state along the axial direction. At this time, the rod body 3 can penetrate the second component 2 and be axially movable relative to the first component 1. The rod body 3 is moved axially and the annular protrusion 205 is radially opposite to one of the other multiple fixed positions 303. The second component 2 is rotated around the axis of the second component 2 so that the annular protrusion 205 is inserted into the other fixed position 303. The second component 2 and the rod body 3 are in a fixed state along the axial direction again. At this time, the rod body 3 is axially fixed relative to the first component 1, and the adjustable telescopic rod is adjusted.

[0058] In the prior art described in the background art, there are no multiple fixing mechanisms between the fixing part and the sleeve, which makes the position of the fixing part installed on the sleeve unadjustable in the telescopic direction of the fixing part relative to the sleeve.

[0059] The first component 1 in this scheme is equivalent to the sleeve in the prior art, the rod body 3 in this scheme is equivalent to the fixing part in the prior art, and the telescopic structure of the rod body 3 relative to the first component 1 in this scheme is equivalent to the telescopic structure of the fixing part relative to the sleeve in the prior art.

[0060] In this solution, a second component 2 is arranged between the first component 1 and the rod body 3, and the annular protrusion on the second component 2 and one of the multiple fixing positions 303 on the rod body 3 can respectively form a fixed state, thereby forming multiple positions between the first component 1 and the rod body 3 that can be used to adjust the distance between the first component 1 and the rod body 3; in the prior art, there is only one fixed position between the fixing portion and the sleeve. If one of the positions in the present application that can be used to adjust the distance between the first component 1 and the rod body 3 is equivalent to the fixed position between the fixing portion and the sleeve in the prior art, then the remaining fixed positions in the present application are equivalent to setting multiple fixed positions between the fixing portion and the sleeve in the prior art. Therefore, the technical problem of how to set multiple fixed positions between the fixing portion and the sleeve is solved.

[0061] In the aforementioned solution, it is mentioned that the second component 2 and the rod body 3 are in a fixed state or a non-fixed state along the axial direction, which is achieved through the following technical solution.

[0062] Reference Figure 5-6 A second groove 204 is provided on the annular protrusion 205, and the second groove 204 penetrates the annular protrusion 205 along the axial direction of the second component 2. The contour of the second groove 204 can accommodate the convex rib 301, and the contour of the second groove 204 can coincide with the contour of the fixing position 303; in the process of the convex rib 301 being inserted into the second groove 204, the fixing position 303 and the second groove 204 have a first overlapping state and a first non-overlapping state. When the fixing position 303 and the second groove 204 are in the first overlapping state, the annular protrusion 205 can be rotatably inserted into the fixing position 303. When the fixing position 303 and the second groove 204 are in the first non-overlapping state, the annular protrusion 205 is restricted outside the fixing position 303.

[0063] Specifically, the second groove 204 is recessed in a radial direction of the annular protrusion 205 and points from the axis of the annular protrusion 205 to the outside of the annular protrusion 205. The second groove 204 penetrates the annular protrusion 205 along the axial direction of the second component 2 and forms openings at both end surfaces of the annular protrusion 205.

[0064] The first groove 102 is connected to the second groove 204, and the rod body 3 can be inserted into the first component 1 along the axial direction. When at least one rib 301 on the rod body 3 penetrates the second groove 204 and is inserted into the first groove 102, the second groove 204 accommodates one of the plurality of fixing positions 303. At this time, the second groove 204 and the fixing position 303 are in a first overlapping state.

[0065] Before the rod body 3 is inserted into the second component 2, any fixed position 303 on the rod body 3 is in a first non-overlapping state relative to the second groove 204 of the second component 2; when the second groove 204 of the second component 2 overlaps with the first groove 102 of the first component 1 along the axial profile, the rod body 3 can be inserted into the first component 1 and the second component 2, wherein the rib 301 is first inserted into the second groove 204 and then into the first groove 102; according to the order in which all the ribs 301 on the rod body 3 are successively inserted into the second groove 204, all the ribs 301 are defined as the first rib, the second rib, ... the Nth rib, respectively, and when the first rib is inserted into the second groove 204, any fixed position 303 on the rod body 3 is relative to The second groove 204 of the second component 2 is in a first non-overlapping state; when the first rib is inserted into the intersection of the second groove 204 and the first groove 102, any fixed position 303 on the rod body 3 is in a first non-overlapping state relative to the second groove 204 of the second component 2; before the first rib is fully inserted into the first groove 102 and the second rib is not inserted into the second groove 204, the fixed position 303 located between the first rib and the second rib is in a first overlapping state with the second groove 204; when the first rib is fully inserted into the first groove 102 and the second rib is inserted into the second component 2, the fixed position 303 located between the first rib and the second rib is in a first non-overlapping state with the second groove 204.

[0066] The above process is the process of inserting the rod body 3 into the first component 1. When the rod body 3 is pulled out from the first component 1, the positional relationship formed between the various components is exactly the opposite order of the positional relationship formed in the above process; the process of the fixing position 303 and the second groove 204 forming the first non-overlapping state or the first overlapping state is exactly the opposite of the process of the aforementioned fixing position and the second groove 204 forming the first non-overlapping state or the first overlapping state, and the rest will not be repeated.

[0067] Except for the fixing position 303 between the first convex rib and the second convex rib, the process of forming the first overlapping state or the first non-overlapping state between the fixing position 303 located between the remaining adjacent convex ribs and the second groove 204 is the same as the process of forming the first overlapping state or the first non-overlapping state between the fixing position 303 between the first convex rib and the second convex rib and the second groove 204, and the rest will not be repeated.

[0068] It can be seen from the above that the technical solution solves the technical problem of how the second component 2 and the rod body 3 form a fixed state and a non-fixed state.

[0069] Furthermore, in the above technical solution, the technical problem of how to connect the second component 2 and the rod body 3 is detailed in the following technical solution.

[0070] Reference Figure 5 , Figure 7In the process of the annular protrusion 205 rotating around the axis, the fixed position 303 and the second groove 204 have a second overlapping state and a second non-overlapping state. When the fixed position 303 and the second groove 204 are in the second non-overlapping state, the rib 301 is restricted outside the second groove 204; when the fixed position 303 and the second groove 204 are in the second overlapping state, the rib 301 can be separated from the second groove 204 along the axial direction.

[0071] Specifically, the second groove 204 penetrates the annular protrusion 205 along the axial direction of the annular protrusion 205, and the intersection of the annular protrusion 205 and the second groove 204 forms a first end face and a second end face along the circumferential direction of the annular protrusion 205, so that the second groove 204 is located between the first end face and the second end face. The annular protrusion 205 can rotate around the axis, and during the rotation of the annular protrusion 205, the second groove 204 will also rotate synchronously with the annular protrusion 205 around the axis of the second component 2.

[0072] Any two adjacent convex ribs on the rod body 3 are defined as convex rib No. 1 and convex rib No. 2. When convex rib No. 1 is fully inserted into the first groove 102 and before convex rib No. 2 is inserted into the second groove 204, the annular protrusion 205 can rotate around the axis; during the rotation of the annular protrusion 205 around the axis, when the first end face and the second end face are both located on the same side of the circumferential direction of the fixed position 303, or one of the first end face and the second end face is located within the fixed position 303, the second groove 204 and the fixed position 303 are in a second non-overlapping state; when the first end face and the second end face are respectively located on both sides of the circumferential direction of the fixed position 303, the second groove 204 and the fixed position 303 are in a second overlapping state.

[0073] It is worth noting that when the fixing position 303 and the second groove 204 are in the first overlapping state and the second overlapping state respectively, the positional relationship between the fixing position 303 and the second groove 204 is the same.

[0074] In the aforementioned technical solution, the technical problem of how the second component 2 and the first component 1 are connected is detailed in the following technical solution.

[0075] Reference Figure 7-Figure 8 The second component 2 is provided with a through, strip-shaped through hole 201, and the two ends of the through hole 201 are respectively a first end 202 and a second end 203; the first component 1 is provided with a threaded hole 104, the rod of the screw 101 penetrates the through hole 201 and is threadedly connected with the threaded hole 104, the head of the screw 101 is located within the contour of the through hole 201, and forms a kinematic pair with the through hole 201.

[0076] In this solution, the rod of the screw 101 penetrates the through hole 201 and is threadedly connected to the threaded hole 104. The head of the screw 101 is located within the contour of the through hole 201 and forms a kinematic pair with the through hole 201. This makes the second component 2 axially restricted by the screw 101 relative to the first component 1, thereby preventing the second component 2 from detaching from the first component 1, thereby solving the technical problem of the unreliable connection between the second component 2 and the first component 1.

[0077] In the aforementioned technical solution, the first groove 102 and the second groove 204 have connection states of being connected and being disconnected; the first groove 102 is arranged on the inner wall of the first component 1, the second component 2 is sleeved on the first component 1, and the second groove 204 is arranged on the second component 2. However, due to the obstruction of the second component 2, the connection and disconnection states of the first groove 102 and the second groove 204 cannot be directly observed by the user; therefore, when the user uses the aforementioned technical solution, if the user needs to know whether the first groove 102 and the second groove 204 are connected, the user needs to constantly adjust the axial position of the rod body 3. When the rod body 3 is axially retractable relative to the first component, the first groove 102 and the second groove 204 are connected. When the rod body 3 is not axially retractable relative to the first component 1, the first groove 102 and the second groove 204 are not connected, which causes certain inconvenience to the user; that is, the aforementioned technical solution has: how to solve the technical problem of enabling the user to quickly know whether the first groove 102 and the second groove 204 are connected.

[0078] Reference Figure 7 , Figure 8 A first groove 102 is provided on the first component 1, and the extension direction of the first groove 102 is the axial direction of the first component 1; when the screw 101 is at the first end 202 of the through hole 201, the second groove 204 is connected with the first groove 102, and any rib 301 can move from the first groove 102 to the second groove 204, or from the second groove 204 to the first groove 102; in the process of the position of the screw 101 relative to the through hole 201 changing from the first end 202 to the second end 203, the second groove 204 and the first groove 102 change from a connected state to a non-connected state.

[0079] In the present solution, the second component 2 is rotated axially relative to the first component 1, so that the position of the screw 101 relative to the through hole 201 changes from the first end 202 to the second end 203, and the second groove 204 and the first groove 102 change from a connected state to a disconnected state. This allows the user to directly observe the position of the screw 101 relative to the through hole 201, and can quickly know whether the first groove 102 and the second groove 204 are connected at this time. Therefore, the present solution solves the technical problem of how to enable the user to quickly know whether the first groove 102 and the second groove 204 are connected.

[0080] In addition, it is worth noting that during the rotation of the second component 2 relative to the first component 1 around the axis, there should be no force acting on the screw 101 and the through hole 201 along the axial direction of the second component 2, otherwise the annular protrusion 205 will not be able to be inserted into the fixing position 303, and the annular protrusion 205 and the fixing position 303 will not be able to form a snap fit; a counterexample, there is a distance between the two ends of the through hole 201 (the first end 202 and the second end 203) in the axial direction of the second component 2, then, when the screw 101 is located at the first end 202, the fixing position 303 and the second groove 2 04 is in the second overlap state, at which time the second component 2 can rotate. During the rotation of the second component 2 relative to the first component 1, that is, during the sliding of the screw 101 from the first end 202 to the second end 203, due to the axial distance between the first end 202 and the second end 203, the second component 2 will move axially relative to the first component 1, which causes the aforementioned fixing position 303 to also move axially, thereby causing the annular protrusion 205 to be unable to be inserted into the aforementioned fixing position 303, that is, the annular protrusion 205 cannot form a snap fit with the fixing position 303. Therefore, the contour of the through hole 201 needs to extend along the circumferential outer surface of the second component 2, and during the rotation of the second component 2 relative to the first component 1, there is no force between the through hole 201 and the screw 101 in the axial direction of the second component 2.

[0081] In the aforementioned technical solution, along the axial direction of the second component 2, if the length of the fixing position 303 is much larger than the length of the annular protrusion 205, the annular protrusion 205 and the fixing position 303 will not be firmly engaged; therefore, in the aforementioned technical solution, there is a technical problem of how to firmly engage the annular protrusion 205 and the fixing position 303.

[0082] Preferably, along the axial direction of the first component 1 , the intervals between two adjacent ribs 301 are equal, and the interval between two adjacent ribs 301 is equal to the length of the annular protrusion 205 extending along the axial direction.

[0083] In the present solution, the lengths of the plurality of fixing positions 303 are all equal, and the length of each fixing position 303 is all equal to the length of the annular protrusion 205. Therefore, when the annular protrusion 205 is inserted into any fixing position 303, the annular protrusion 205 will form a tight engagement state with the fixing position 303. Even if the first component 1 is tilted in the vertical direction, or the adjustable telescopic rod is affected by external vibrations, the annular protrusion 205 is not easy to detach from the fixing position 303, thereby improving the tighter engagement between the annular protrusion 205 and the fixing position 303, thereby solving the technical problem of how to solve the firm engagement between the annular protrusion 205 and the fixing position 303 in the aforementioned technical solution.

[0084] In the above technical solution, the technical problem of how to reduce the length of the rod body 3 exposed outside the first component 1 as much as possible so that the expansion and contraction amount between the first component 1 and the rod body 3 is reasonable is solved by the following solution.

[0085] Any rib 301 can be accommodated inside the first component 1 .

[0086] In the aforementioned technical solution, if only part of the convex rib 301 can be accommodated in the first component 1, the length of the rod body 3 extending into the first component 1 is less than the length of the part of the rod body 3 where multiple convex ribs 301 are set, and the length of the rod body 3 relative to the first component 1 cannot be adjusted to the shortest, resulting in a technical problem of unreasonable expansion and contraction between the first component 1 and the rod body 3; whereas in the present solution, since any convex rib 301 can be accommodated inside the first component 1, that is, the rod body 3 can drive all the convex ribs 301 to be inserted into the first component 1, the length of the rod body 3 relative to the first component 1 can be adjusted to the shortest, making the expansion and contraction between the first component 1 and the rod body 3 more reasonable.

[0087] Example 2

[0088] In this embodiment, see Fig. 9 , a horizontal handle is proposed, which includes the adjustable telescopic rod in Example 1.

[0089] Specifically, the horizontal handle includes a vertical tube and a pair of adjustable telescopic rods, which are coaxially arranged and respectively installed at both ends of the vertical tube; it also includes a fourth component 4, which is cylindrical and made of rubber material. The fourth component 4 is sleeved on one end of the rod body 3 away from the first component 1, and the inner surface of the fourth component 4 is tightly fitted with the outer surface of the rod body 3.

[0090] In the technical solution of Example 1, the rod body 3 of the adjustable telescopic rod is a linear rod-shaped structure. When the user uses it, that is, when the user holds the horizontal handle, the circumferential outer surface of the rod body 3 is easy to slide between the user's palm;

[0091] In the technical solution of the horizontal handle of this embodiment, due to the setting of the fourth component 4, direct contact between the user's palm and the adjustable telescopic rod is avoided. When using the horizontal handle, the user can hold the palm on the fourth component. Since the fourth component 4 is made of rubber material, on the one hand, the rubber is soft and elastic, and elastic contact is formed between the fourth component 4 and the palm and the adjustable telescopic rod, respectively, making the user feel more comfortable. On the other hand, the rubber surface has a high friction coefficient, which is conducive to increasing the friction between the user's palm and the fourth component, and between the fourth component and the adjustable telescopic rod, so that it is not easy to slip between the user's palm and the adjustable telescopic rod, and between the fourth component and the adjustable telescopic rod, thereby solving the aforementioned technical problem of easy sliding between the user's palm and the adjustable telescopic rod when the user uses it.

[0092] The structure and effect of the adjustable telescopic rod used in the horizontal handlebar in this embodiment are exactly the same as the structure and effect of the adjustable telescopic rod in the aforementioned embodiment 1, and will not be repeated here. Example 3

[0093] In this embodiment, a vehicle is provided, comprising the above-mentioned adjustable telescopic rod; the vehicle is one of a bicycle, a scooter, an electric scooter, and an electric bicycle.

[0094] The structure and effect of the adjustable telescopic rod used in the vehicle in this embodiment are exactly the same as the structure and effect of the adjustable telescopic rod in the aforementioned embodiment 1, and will not be repeated here.

[0095] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
