Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a support kit, a pull rod assembly, and a pull rod speaker. Background Technology

[0002] Currently, the principle behind the lever mechanism of speakers with pull rods on the market is as follows: when the lever needs to be pulled out, pressing the switch or button transmits the movement through a transmission rod to the locking mechanism at the bottom of the tube, unlocking the lock and allowing the lever to be pulled out. When the lever needs to be retracted, the same process is required: pressing the switch or button to unlock the lever and retracting it.

[0003] Because the inner tube of the movable pull rod is relatively long, a longer transmission rod is required. As the length of the transmission rod increases, the overall strength decreases, and the axial force generated during pressing can easily cause deformation of the transmission rod. Prolonged use may even lead to damage to the transmission rod, affecting the product's lifespan. Utility Model Content

[0015] This utility model proposes a support kit 200. Figure 1 This is one embodiment of the present utility model.

[0016] In this embodiment of the utility model, combined with Figure 2 The support kit 200 is applied to the tie rod structure 100, which includes an inner tube 101 and a transmission rod 102 movably disposed within the inner tube 101. The support kit 200 has a sleeve hole 11 for sleeved with the transmission rod 102, and the outer edge of the support kit 200 in the diameter direction of the sleeve hole 11 is used to abut against the inner wall of the inner tube 101.

[0017] In the technical solution of this utility model, the support kit 200 is provided on the transmission rod 102 of the pull rod structure 100, so that the support kit 200 provides support between the transmission rod 102 and the inner tube 101, preventing the transmission rod 102 from bending and deforming under pressure, thereby improving the strength of the transmission rod 102 and ensuring the service life of the transmission rod 102.

[0018] When a speaker with a pull rod structure 100 is playing music, the transmission rod 102 is easily driven by sound waves, causing it to swing and impact the inner wall of the inner tube 101, producing abnormal noise and affecting the speaker's acoustic performance. In this invention, the support kit 200 abuts against the inner wall of the inner tube 101 to prevent the transmission rod 102 from impacting the inner wall of the inner tube 101.

[0019] Furthermore, in the prior art, the transmission rod 102 is generally made of fiberglass. By adopting the solution of this embodiment, since a support is added to the transmission rod 102, the support thickness can be reduced from the commonly used 4mm to 2.5mm, further controlling costs and reducing the necessary space in the inner tube 101 for installing the transmission rod 102. The specific size of the support kit 200 can be set according to the space available in the inner tube 101.

[0020] To reduce the friction between the support kit 200 and the inner wall of the inner tube 101, and to make the transmission rod 102 operate more smoothly, in one embodiment, such as Figure 1 As shown, the support kit 200 has an abutment protrusion 12 located on the outer edge of the support kit 200 and used to abut against the inner wall of the inner tube 101. By providing the abutment protrusion 12, only a portion of the outer edge of the support kit 200 actually abuts against the inner wall of the inner tube 101; that is, the abutment protrusion 12 abuts against the inner wall of the inner tube 101. This reduces the contact area between the support kit 200 and the inner wall of the inner tube 101, significantly reducing the friction between them.

[0021] In one embodiment, the width of the abutting protrusion 12 gradually decreases in the direction away from the sleeve hole 11, so as to further reduce the contact area between the abutting protrusion 12 and the inner wall of the inner tube 102, thereby reducing friction. This gradually narrowing or gradually sharpening design of the abutting protrusion 12 ensures that the end of the abutting protrusion 12 near the sleeve hole 11 still has a large contact area, and can also ensure the strength of the abutting protrusion 12 itself, preventing it from falling off due to long-term friction with the inner wall of the inner tube 101 during use. This strengthens the structural strength of the support kit 200 itself, ensures structural integrity, reduces the probability of replacing the support kit 200, and makes the product more durable.

[0022] The specific shape of the abutting protrusion 12 is not limited and can be a cone, a frustum or other shapes. When the abutting protrusion 12 is a cone or a frustum, the smaller bottom surface contacts the inner wall of the inner tube 101.

[0023] To prevent the outer edge of the support kit 200 from scratching the inner wall of the inner tube 101 when it moves with the transmission rod 102, the support kit 200 is made of an elastic material, so that the support kit 200 has a certain amount of elastic contraction, preventing scratches or even damage caused by rigid contact with the inner wall of the inner tube 101. The specific material of the support kit 200 is not limited and can be natural latex, rubber, etc.

[0024] To ensure a more secure fit of the support kit 200 onto the transmission rod 102, in one embodiment, the diameter of the sleeve hole 11 is smaller than the diameter of the transmission rod 102, with an interference fit between them. This design ensures a more secure connection, preventing the support kit 200 from easily shifting relative to the transmission rod 102 and becoming loose during long-term use, thus reducing replacement rates and ensuring product quality. Furthermore, it guarantees the support function for the transmission rod 102. If relative movement occurs between the transmission rod 102 and the support kit 200, the support function will be reduced to varying degrees depending on the position of the shifted support kit 200.

[0025] In one embodiment, the difference between the diameter of the sleeve hole 11 and the radius of the transmission rod 102 is α, where 0.05mm ≤ α ≤ 0.15mm. This ensures an interference fit between the sleeve hole 11 and the transmission rod 102, and that the interference amount is moderate. This prevents assembly difficulties or tearing of the support kit 200 due to a large diameter difference, and also prevents relative movement between the support kit 200 and the transmission rod 102 due to a small diameter difference. More specifically, α is preferably 0.1mm.

[0026] To ensure a secure connection between the support sleeve and the transmission rod 102, and to further prevent relative movement between the support kit 200 and the transmission rod 102, in one embodiment, the support kit 200 includes a sleeve body 1 and an augmentation kit 2. In the depth direction of the sleeve hole 11, the augmentation kit 2 connects to the sleeve body 1 and is disposed at at least one end of the sleeve body 1. The sleeve body 1 and the augmentation kit 2 together form the sleeve hole 11. The augmentation kit 2 increases the area of ​​the hole wall of the sleeve hole 11, thereby increasing the contact area between the sleeve hole 11 and the transmission rod 102, thus increasing the friction between them, and making the support kit 200 more securely fitted onto the transmission rod 102.

[0027] Furthermore, the connection method between the sleeve body 1 and the growth kit 2 is not limited. It can be achieved through hot-melt connection, bonding, or other methods. In this embodiment, the sleeve body 1 and the growth kit are integrally formed, eliminating the connection process between the sleeve body 1 and the growth kit 2. Compared with the separate configuration, this reduces the risk of breakage and damage at the connection between the sleeve body 1 and the growth kit 2. The friction between the sleeve body 1, the growth kit 2, and the transmission rod 102 can also be kept uniform, preventing separation during long-term use due to differences in gaps or interference fits between the two, thus ensuring structural integrity and completing the production process in one step.

[0028] This utility model also provides a pull rod assembly 1000, which includes the pull rod structure 100 and at least two support kits 200, with each support kit 200 spaced apart along the length direction of the transmission rod 102 of the pull rod structure 100. By supporting the transmission rod 102 at different positions along its length direction with at least two support kits 200, the strength of the transmission rod 102 is further improved, and the possibility of the transmission rod 102 shaking due to the influence of sound waves is further reduced.

[0029] The pull rod assembly 1000 includes the support kit 200. The specific structure of the support kit 200 is as described in the above embodiments. Since the pull rod assembly 1000 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.

[0030] In one embodiment, such as Figure 3As shown, the pull rod assembly 1000 includes three support kits 200. The appropriate number of support kits ensures the strength of the transmission rod 102 while avoiding the problems of structural complexity and increased cost caused by redundant support kits 200. Specifically, the preferred positions of the three support kits 200 are near either end of the transmission rod 102 and in the middle, respectively, to provide the best support.

[0031] This utility model also proposes a trolley speaker, which includes a speaker and a trolley assembly 1000. The trolley assembly 1000 is connected to the speaker and is used to lift and move the speaker. The trolley speaker with the trolley structure 100 has the beneficial effects of high strength of the trolley assembly 1000 and the audio played not being affected by the transmission rod 102.

[0032] The trolley speaker includes the trolley assembly 1000. The specific structure of the trolley assembly 1000 is as described in the above embodiments. Since this trolley speaker 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.
