Description

Technical Field

[0001] This invention relates to the field of speaker equipment technology, and in particular to a pull rod structure and a device having a pull rod structure. Background Technology

[0002] For easy portability, heavier speakers are usually equipped with a handle and wheels. The handle can be retracted when not in use, without affecting the appearance. When needed, the handle can be pulled out to move the speaker, greatly reducing the user's burden.

[0003] In related technologies, the inner and outer tubes of the pull rod structure are fixed by a ball that can move left and right and a through hole opened at different heights in the outer tube. However, this method requires holes to be made in the outer tube. Without holes, the ball cannot be inserted, resulting in the pull rod being pulled out only to a few fixed heights. Moreover, the holes will affect the strength of the outer tube. Summary of the Invention

[0004] The main objective of this invention is to provide a tie rod structure and a device having the tie rod structure, with the aim of providing a tie rod structure that can be adjusted in multiple levels of height.

[0005] To achieve the above objectives, the present invention proposes a tie rod structure, including a telescopic rod structure, wherein the telescopic rod structure comprises:

[0006] The outer sleeve extends along a first direction, with one end in the first direction being open to allow the inner tie rod to pass through.

[0007] The inner tie rod is slidably disposed within the outer sleeve along the first direction;

[0008] A locking structure includes a rotating part and a rotating mating part. The rotating part is rotatably mounted to one end of the inner tie rod along the radial direction of the outer sleeve. The rotating mating part is disposed on the inner wall of the outer sleeve. The rotating part has a rotating state and a non-rotating state. In the rotating state, the rotating part and the rotating mating part can move relative to each other. In the non-rotating state, the rotating part and the rotating mating part can be fixed relative to each other.

[0009] The limiting structure includes a limiting part movably installed relative to the inner tie rod and an anti-rotation fitting part provided on the rotating part. The limiting part has a limiting position and an avoidance position in its active stroke. Corresponding to the limiting position, the limiting part and the anti-rotation fitting part engage to prevent rotation, so that the rotating part is in the anti-rotation state. Corresponding to the avoidance position, the limiting part avoids the anti-rotation fitting part, so that the rotating part is in the rotating state.

[0010] Optionally, the limiting part is slidably disposed relative to the inner pull rod along a first direction.

[0011] Optionally, the anti-rotation fitting part includes an anti-rotation protrusion protruding along the axial direction of the rotating part, and an anti-rotation flat part is formed on the side of the anti-rotation protrusion.

[0012] The limiting part has an abutting flat part that faces the anti-rotation fitting part and extends along a first direction. During the active stroke of the limiting part, the abutting flat part abuts against the anti-rotation flat part so that the rotating part is in the anti-rotation state.

[0013] Optionally, multiple anti-rotation leveling parts are provided and are distributed around the anti-rotation protrusion.

[0014] Optionally, the anti-rotation protrusion is coaxially arranged with the rotating part.

[0015] Optionally, the telescopic rod structure further includes a mounting bracket, which is fixed to one end of the inner pull rod by screws, and the rotating part is rotatably mounted on the mounting bracket.

[0016] Optionally, the tie rod structure further includes:

[0017] A handle is fixedly connected to the inner pull rod, and a receiving groove is formed on the handle.

[0018] A pressing member is movably disposed within the receiving groove, the pressing member abutting against the side wall of the receiving groove facing the inner pull rod, and is fixedly connected to the limiting portion; and,

[0019] An elastic element connects the pressing element to the side wall of the handle element.

[0020] Optionally, two telescopic rod structures are provided;

[0021] The handle is fixedly connected to both of the inner pull rods;

[0022] The pressing component is fixedly connected to both of the limiting parts.

[0023] Optionally, the rotating engagement portion includes a rack, and the rotating portion includes a gear that meshes with the rack.

[0024] Optionally, the outer sleeve is provided with a guide member for guiding the inner tie rod to slide along a first direction.

[0025] Optionally, the guide includes:

[0026] A guide portion, disposed within the outer sleeve, has guide cavities extending in a first direction and open at both ends; and,

[0027] A cover portion is provided on the guide portion and covers the opening of the outer sleeve;

[0028] The inner tie rod is slidably connected to the side wall of the guide cavity.

[0029] The present invention also proposes a device with a tie rod structure, the device having a tie rod structure including a telescopic rod structure, the telescopic rod structure including:

[0030] The outer sleeve extends along a first direction, with one end in the first direction being open to allow the inner tie rod to pass through.

[0031] The inner tie rod is slidably disposed within the outer sleeve along the first direction;

[0032] A locking structure includes a rotating part and a rotating mating part. The rotating part is rotatably mounted to one end of the inner tie rod along the radial direction of the outer sleeve. The rotating mating part is disposed on the inner wall of the outer sleeve. The rotating part has a rotating state and a non-rotating state. In the rotating state, the rotating part and the rotating mating part can move relative to each other. In the non-rotating state, the rotating part and the rotating mating part can be fixed relative to each other.

[0033] The limiting structure includes a limiting part movably installed relative to the inner tie rod and an anti-rotation fitting part provided on the rotating part. The limiting part has a limiting position and an avoidance position in its active stroke. Corresponding to the limiting position, the limiting part and the anti-rotation fitting part engage to prevent rotation, so that the rotating part is in the anti-rotation state. Corresponding to the avoidance position, the limiting part avoids the anti-rotation fitting part, so that the rotating part is in the rotating state.

[0034] Optionally, the device with the pull rod structure includes a speaker.

[0035] In the technical solution of this invention, the inner pull rod is slidably disposed within the outer sleeve along a first direction, and the rotating part is rotatably mounted on one end of the inner pull rod along the radial direction of the outer sleeve. The rotating mating part is disposed on the inner wall of the outer sleeve, and the limiting part is movably mounted relative to the inner pull rod. Thus, when the inner pull rod slides relative to the outer sleeve, the rotating part engages with the rotating mating part, allowing the rotating part to rotate relative to the inner pull rod during its sliding motion, achieving a rolling posture. This enables multi-level adjustment of the length of the telescopic rod structure to adapt to different usage requirements. The limiting part is movable relative to the inner pull rod; when the limiting part moves to the limiting position, it engages with the anti-rotation mating part to restrict the rotation of the rotating part, thereby limiting the sliding of the inner pull rod, and the overall telescopic rod structure remains fixed.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] For easy portability, heavier speakers are usually equipped with a handle and wheels. The handle can be retracted when not in use, without affecting the appearance. When needed, the handle can be pulled out to move the speaker, greatly reducing the user's burden.

[0051] In related technologies, the inner and outer tubes of the pull rod structure are fixed by a ball that can move left and right and a through hole opened at different heights in the outer tube. However, this method requires holes to be made in the outer tube. In places without holes, the ball cannot be inserted, resulting in the pull rod being pulled out only to a few fixed heights. Moreover, the holes will affect the strength of the outer tube.

[0052] To address the aforementioned problems, this invention proposes a tie rod structure and a device having the tie rod structure, aiming to provide a tie rod structure that can be adjusted in multiple levels of height.

[0053] Figures 1 to 6 This is a schematic diagram of an embodiment of a tie rod structure 100 provided by the present invention.

[0054] Please refer to Figures 1 to 3This invention proposes a pull rod structure 100, including a telescopic rod structure 1. The telescopic rod structure 1 includes an outer tube 11, an inner pull rod 12, a locking structure 13, and a limiting structure 14. The outer tube 11 extends along a first direction, with one end in the first direction being open to allow the inner pull rod 12 to pass through. The inner pull rod 12 is slidably disposed within the outer tube 11 along the first direction. The locking structure 13 includes a rotating part 131 and a rotating mating part 132. The rotating part 131 is rotatably mounted to one end of the inner pull rod 12 along the radial direction of the outer tube 11. The rotating mating part 132 is disposed on the inner wall of the outer tube 11. The rotating part 131 has a rotating state and a non-rotating state. In the rotating part 131 and the rotating mating part 132 are movable relative to each other in the anti-rotation state, and in the anti-rotation state, the rotating part 131 and the rotating mating part 132 are fixed relative to each other. The limiting structure 14 includes a limiting part 141 movably installed relative to the inner pull rod 12 and an anti-rotation mating part 142 provided on the rotating part 131. The limiting part 141 has a limiting position and an avoidance position in its active stroke. Corresponding to the limiting position, the limiting part 141 and the anti-rotation mating part 142 engage in anti-rotation mating so that the rotating part 131 is in the anti-rotation state. Corresponding to the avoidance position, the limiting part 141 avoids the anti-rotation mating part 142 so that the rotating part 131 is in the rotating state.

[0055] It should be noted that the rotation state refers to the state in which the rotating part 131 can rotate relative to the inner pull rod 12. The relative rotation between the rotating part 131 and the inner pull rod 12 is caused by the movement of the inner pull rod 12 along the first direction. Therefore, when the rotating part 131 is in the rotation state, the inner pull rod 12 can slide relative to the outer sleeve 11, that is, the length of the entire pull rod structure 100 can be adjusted. The anti-rotation state refers to the state in which the rotating part 131 cannot rotate relative to the inner pull rod 12. That is, when the rotating part 131 is in the anti-rotation state, the inner pull rod 12 cannot slide inside the outer sleeve, and the length of the entire pull rod structure 100 is in a non-adjustable state.

[0056] Wherein, the first direction is the length direction of the outer sleeve 11.

[0057] It should be noted that the limiting position and the avoidance position refer to the relative positions of the limiting part 141 and the inner pull rod 12. When the limiting part 141 is in the limiting position, it cooperates with the anti-rotation fitting part 142 on the rotating part 131, thereby restricting the rotation of the rotating part 131, and thus keeping the inner pull rod 12 and the outer tube 11 in a fixed state. When the limiting part 141 is in the avoidance position, the limiting part 141 and the anti-rotation fitting part 142 are in contact, the rotating part 131 can rotate, and the inner pull rod 12 can slide in the outer tube 11.

[0058] It is understood that the inner diameter of the outer sleeve 11 is larger than the outer diameter of the inner tie rod 12, so that the inner tie rod 12 can be fitted into the outer sleeve 11 from the opening of the outer sleeve 11.

[0059] Furthermore, the outer sleeve 11 and the inner pull rod 12 are made of materials with a certain degree of hardness to prevent the outer sleeve 11 and the inner pull rod 12 from breaking due to their weak load-bearing capacity when the speaker is pulled.

[0060] In the technical solution of this invention, the inner pull rod 12 is slidably disposed within the outer sleeve 11 along a first direction, the rotating part 131 is rotatably mounted on one end of the inner pull rod 12 along the radial direction of the outer sleeve 11, the rotating mating part 132 is disposed on the inner wall of the outer sleeve 11, and the limiting part 141 is movably mounted relative to the inner pull rod 12. Thus, when the inner pull rod 12 slides relative to the outer sleeve 11, the rotating part 131 and the rotating mating part 132 are movably mounted on the inner wall of the outer sleeve 11. The engaging part 132 engages with the inner pull rod 12, allowing the rotating part 131 to rotate relative to the inner pull rod 12 during the sliding process, thus achieving a rolling posture and adjusting the length of the telescopic rod structure 1. The limiting part 141 is movable relative to the inner pull rod 12. When the limiting part 141 moves to the limiting position, it engages with the anti-rotation engaging part 142 to restrict the rotation of the rotating part 131, thereby restricting the sliding of the inner pull rod 12, and keeping the entire telescopic rod structure 1 fixed.

[0061] Please refer to Figures 4 to 6 In this embodiment, the pull rod structure 100 further includes a handle 2, a pressing member 3, and an elastic member 4. The handle 2 is fixedly connected to the inner pull rod 12, and a receiving groove 21 is formed on the handle 2. The pressing member 3 is movably disposed in the receiving groove 21, and the pressing member 3 abuts against the side wall of the receiving groove 21 facing the inner pull rod 12, and is fixedly connected to the limiting part 141. The elastic member 4 connects the pressing member 3 and the side wall of the handle 2.

[0062] Thus, when the speaker is dragged by the handle 2, the pressing member 3 is pressed, causing the limiting part 141 to move from the limiting position to the avoidance position, thereby removing the restriction on the rotating part 131. This allows the inner pull rod 12 to slide relative to the outer tube 11, thereby adjusting the length to suit different users. The elastic member 4 ensures that after the pressing member 3 is released, its elasticity allows the limiting part 141 to return from the avoidance position to the limiting position, thereby locking the inner pull rod 12 and the outer tube 11, making it convenient to use.

[0063] The elastic element 4 can be a spring, or other elastic structures or components.

[0064] To facilitate the user pressing the pressing member 3, a portion of the pressing member 3 protrudes from the receiving groove 21.

[0065] To improve the stability of the handle 2 when pulling the speaker, in this embodiment, two telescopic rod structures 1 are provided. The handle 2 is fixedly connected to both inner pull rods 12, and the pressing member 3 is fixedly connected to both limiting parts 141. In this way, the handle 2 is supported by the two telescopic rod structures 1, resulting in better stability.

[0066] Please refer to Figure 3 In this embodiment, the rotating engagement part 132 includes a rack, which is fixedly installed on one side wall of the outer sleeve 11. The rotating part 131 includes a gear that meshes with the rack. When the inner pull rod 12 slides along the first direction, the meshing of the gear and the rack causes the gear to rotate relative to the inner pull rod 12, and the gear as a whole is in a rolling posture. In another embodiment, the rotating engagement part 132 and the rotating part 131 adopt a ratchet structure; other structures that can convert the linear motion of the inner pull rod 12 into the rotational motion of the rotating part 131 are also acceptable.

[0067] Due to the arrangement of the rotating mating part 132 and the rotating part 131, there will inevitably be a gap between the inner tie rod 12 and the outer sleeve 11, which may cause the inner tie rod 12 to tilt during sliding. In order to improve the stability of the inner tie rod 12 sliding in the outer sleeve 11, a guide 16 is provided on the outer sleeve 11. The guide 16 is used to guide the inner tie rod 12 to slide along the first direction, thereby improving the stability of the overall structure.

[0068] For further information, please refer to [link / reference]. Figure 4The guide 16 is disposed near the opening of the outer tube 11. This arrangement ensures that the guide 16 can guide the inner pull rod 12 at any position within the outer tube 11.

[0069] Specifically, the guide member 16 includes a guide portion 161 and a cover portion 162. The guide portion 161 is disposed inside the outer sleeve 11 and has a guide cavity extending in a first direction with open ends. The cover portion 162 is disposed on the guide portion 161 and covers the opening of the outer sleeve 11. The inner pull rod 12 is slidably connected to the side wall of the guide cavity. In this way, the guide portion 161 guides the sliding of the inner pull rod 12, while the cover portion 162 can cover the opening of the outer sleeve 11, thereby reducing the possibility of external impurities falling into the outer sleeve 11.

[0070] The guide portion 161 is a sleeve.

[0071] It is understandable that when the inner pull rod 12 needs to be slid to adjust the length of the overall telescopic rod structure 1, there must be a force acting on the inner pull rod 12 in the first direction. In order to facilitate the user to operate the inner pull rod 12 and the limiting part 141 at the same time, in this embodiment, the limiting part 141 is slidably arranged relative to the inner pull rod 12 in the first direction. In this way, the operation is more convenient and the assembly is more convenient.

[0072] In another embodiment, the limiting part 141 is slidably disposed radially along the outer sleeve 11 relative to the inner pull rod 12, thereby reducing the possibility of accidental contact with the limiting part 141.

[0073] In order to restrict the rotation of the rotating part 131 when the limiting part 141 is in the limiting position, in this embodiment, the anti-rotation fitting part 142 includes an anti-rotation protrusion protruding along the axial direction of the rotating part 131, and an anti-rotation flattening part 1421 is formed on the side of the anti-rotation protrusion; the limiting part 141 has an abutting flattening part 1411 extending toward the anti-rotation fitting part 142 and along a first direction, and the abutting flattening part 1411 is positioned during the active stroke of the limiting part 141. The abutting flattening part 1411 abuts against the anti-rotation flattening part 1421, thereby restricting the rotation of the rotating part 131, so that the rotating part 131 is in the anti-rotation state; thus, by the abutting flattening part 1411 abutting against the anti-rotation flattening part 1421, the rotation of the anti-rotation flattening part 1421 can be restricted, thereby restricting the rotation of the rotating part 131, so that the rotating part 131 is in the anti-rotation state. When the abutting flattening part 1411 separates from the anti-rotation flattening part 1421, the limiting part 141 is in the rotation state.

[0074] In another embodiment, a portion of the rotating part 131 forms the anti-rotation engagement part 142. Specifically, when the rotating part 131 is the gear, the limiting part 141 is provided with corresponding teeth. When the limiting part 141 moves to the point where the teeth mesh with the side of the gear away from the rack, it can also limit the rotation of the gear.

[0075] Furthermore, multiple anti-rotation leveling parts 1421 are provided and are distributed around the anti-rotation protrusion. With this arrangement, when the anti-rotation protrusion rotates with the rotating part 131, it does not need to rotate one full turn, thereby increasing the number of adjustment levels of the overall telescopic rod structure 1.

[0076] Specifically, in this embodiment, the anti-rotation protrusion is coaxially arranged with the rotating part 131, and the anti-rotation mating part 142 is set as a regular polygon, with its multiple sides forming multiple anti-rotation flat parts 1421.

[0077] Furthermore, it can be understood that the more sides the anti-rotation fitting part 142 has, the more adjustment levels the overall telescopic rod structure 1 has. However, when the size of the anti-rotation fitting part 142 is limited, the shorter its sides are, the smaller the contact area with the abutting flat part 1411 may be, which may lead to unstable contact. Therefore, in this embodiment, the anti-rotation fitting part 142 is preferably set as a regular quadrilateral.

[0078] To facilitate the assembly of the limiting structure 14 with the inner pull rod 12, the telescopic rod structure 1 also includes a mounting bracket 15. The mounting bracket 15 is fixed to one end of the inner pull rod 12 by screws. The rotating part 131 is rotatably mounted on the mounting bracket 15, and the limiting part 141 is slidably connected to the mounting bracket 15. This facilitates installation and allows for the replacement of easily worn parts such as the rotating part 131 and the anti-rotation fitting part 142 as a whole.

[0079] Please refer to Figure 7 The present invention also proposes a device 1000 having a pull rod structure 100. The device 1000 having a pull rod structure 100 includes a pull rod structure 100. The specific structure of the pull rod structure 100 is as described in the above embodiments. Since the device having a pull rod structure 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0080] The device 1000 with the pull rod structure 100 includes a speaker or a suitcase.

[0081] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
