Description

Technical Field

[0001] This utility model belongs to the field of aluminum roller technology, specifically an aluminum roller that facilitates gravity adjustment. Background Technology

[0002] Aluminum rollers are used in many fields due to their light weight and durability. However, their light weight also limits their applicability in some areas. To improve ease of use, the weight of aluminum rollers needs to be adjustable.

[0003] However, the following problems were found in the implementation of the relevant technology: Although the existing aluminum rollers can adjust their own weight, the adjustment method is relatively complicated and not convenient to use. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an aluminum roller that facilitates gravity adjustment, which has the advantages of simple adjustment and convenient use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum roller for convenient gravity adjustment, comprising a roller sleeve and an adjustment assembly installed inside the roller sleeve. The adjustment assembly includes a connecting cylinder fixedly inserted into the middle of the inner side of the roller sleeve. Both ends of the connecting cylinder are threadedly connected to adjustment rods. A blocking plate is integrally formed at the end of the adjustment rod away from the roller sleeve, and the blocking plate abuts against the corresponding side of the roller sleeve. A plurality of first annular counterweights and second annular counterweights are sequentially sleeved on the side of the adjustment rod near the blocking plate, and the first annular counterweights are located between the second annular counterweights and the blocking plate. A limiting ring is sleeved on the side wall of the adjustment rod, and the limiting ring abuts against the corresponding side of the second annular counterweight.

[0006] Preferably, the limiting ring has two symmetrically integrally formed fixing pieces on one side, and each fixing piece has a fixing hole in the middle.

[0007] Preferably, a fastening screw is screwed between the two fixing holes, and a washer is fitted on the side wall of the fastening screw.

[0008] Preferably, the blocking plate has a circular structure, and the outer wall of the blocking plate is flush with the outer wall of the roller sleeve.

[0009] Preferably, a connecting rod is integrally formed in the middle of the side of the blocking plate away from the roller sleeve.

[0010] Preferably, the blocking plate and the connecting rod, and the blocking plate and the adjusting rod are both integrally cast structures.

[0011] Preferably, a label is adhered to the middle of one side of the outer wall of the roller sleeve, and the surface of the label is covered with a protective film.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adjusts the weight of the aluminum roller by adding or removing the first and second annular counterweights on the adjusting rod. After adjustment, the roller is limited by a limiting ring and then tightened to the inside of the connecting cylinder to complete the adjustment, making the weight adjustment more convenient.

[0014] 2. This utility model uses two types of counterweights, the first and the second, to adjust the self-weight. Since the two types of counterweights have different weights, the range of self-weight adjustment is more flexible after different combinations. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides an aluminum roller for convenient gravity adjustment, including a roller sleeve 1 and an adjustment assembly installed inside the roller sleeve 1. The adjustment assembly includes a connecting cylinder 2 fixedly inserted into the middle of the inner side of the roller sleeve 1. Both ends of the connecting cylinder 2 are threadedly connected to an adjustment rod 3. The side wall of the adjustment rod 3 near the connecting cylinder 2 is threaded, and the end of the adjustment rod 3 away from the roller sleeve 1 is integrally formed with a blocking plate 4, which abuts against the corresponding side of the roller sleeve 1 to ensure the sealing of the roller sleeve 1. A plurality of first... The first annular counterweight 5 and the second annular counterweight 6 are flexibly selected according to the need for counterweighting. The first annular counterweight 5 is located between the second annular counterweight 6 and the blocking plate 4, and the second annular counterweight 6 is close to the connecting cylinder 2. This makes the counterweighting more balanced. The side wall of the adjusting rod 3 is fitted with a limiting ring 7, and the limiting ring 7 abuts against the corresponding side of the second annular counterweight 6. The limiting ring 7 is used for limiting, so that the first annular counterweight 5 and the second annular counterweight 6 are stably abutting against the corresponding side of the blocking plate 4.

[0023] Specifically, the limiting ring 7 has two fixed pieces 8 integrally formed symmetrically on one side. The limiting ring 7 has a certain elasticity and can tighten the two fixed pieces 8 so that they fit together. The two fixed pieces 8 are provided with fixing holes in the middle.

[0024] Furthermore, a fastening screw 9 is screwed between the two fixing holes. Tightening the fixing screw 9 keeps the limiting ring 7 clamped, thus stably fixing it to the corresponding side of the adjusting rod 3. A washer (not shown in the figure) is sleeved on the side wall of the fastening screw 9 to prevent the corresponding sides of the fastening screw 9 and the fixing plate 8 from wearing each other.

[0025] Furthermore, the blocking plate 4 has a circular structure, and the outer wall of the blocking plate 4 is flush with the outer wall of the roller sleeve 1, ensuring the integrity and aesthetics of the aluminum roller.

[0026] It is worth noting that a connecting rod 10 is integrally formed in the middle of the side of the blocking plate 4 away from the roller sleeve 1. The connecting rod 10 is used to connect with the external structure.

[0027] It is worth noting that the connection between the blocking plate 4 and the connecting rod 10, and the connection between the blocking plate 4 and the adjusting rod 3 are both integrally cast structures. The integrally cast structure has high structural strength and is not easily damaged after long-term use.

[0028] It is worth mentioning that a label 11 is attached to the middle of the outer wall of one side of the roller sleeve 1. The label 11 is marked with the number of the current aluminum roller for easy identification. The label 11 is also covered with a protective film to prevent the number from becoming illegible due to wear.

[0029] Working principle: Multiple first annular counterweights 5 and second annular counterweights 6 are selected according to the required counterweight, and are fitted onto the side wall of the adjusting rod 3 and abut against the blocking plate 4 (e.g., Figure 2 Then, the limiting ring 7 is placed on the side wall of the adjusting rod 3 and abuts against the second annular counterweight 6. Next, the two fixing plates 8 are pressed tightly and the fastening screws 9 are tightened. Then, the adjusting rod 3 is continuously screwed into the connecting cylinder 2 until the blocking plate 4 abuts against the roller sleeve 1, making it easier to adjust the weight.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
