Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ball guardrail, specifically relates to the ball guardrail convenient to assemble. BACKGROUND

[0002] In the modern logistics, warehousing, production line and other scenes, the ball guardrail is widely used because of its low friction, easy conveying, high bearing and other characteristics. The traditional ball guardrail usually adopts a fixed installation mode. Once damaged or needs to be replaced, the whole needs to be disassembled, which not only increases the complexity of maintenance, but also affects the overall production efficiency, and even causes high maintenance cost. Therefore, how to improve the assembly convenience of the ball guardrail, reduce the maintenance difficulty and realize the modular replacement has become one of the important directions of the optimization of industrial conveying system.

[0003] The traditional ball guardrail usually adopts a whole fixed structure, and the ball assembly is closely connected with the guardrail frame. Once a ball is damaged or worn, the whole needs to be disassembled, which not only increases the maintenance time, but also increases the labor and material cost. In addition, due to the limitation of the ball installation mode, high installation precision is usually required, otherwise the ball may be jammed and the conveying may not be smooth, which affects the use effect. Such fixed structure is difficult to maintain in daily use, especially in the conveying system with high frequency operation. If the maintenance is not timely, the whole production line may be shut down, causing economic loss.

[0004] In view of the above, the ball guardrail convenient to assemble is provided to solve the above problems. Through the cooperation between the connecting piece and the inner frame, the installation mode of the ball is optimized, so that the ball is not restricted too much during the fixing process, and only needs to ensure that the edge of the ball outward is flush to complete the installation. At the same time, it is also convenient to disassemble, which is beneficial to the subsequent maintenance problem. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the ball guardrail convenient to assemble is provided to solve the problems in the above background technology.

[0006] To achieve the above purpose, the utility model realizes the following technical scheme:

[0031] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] In the description of this utility model, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] This application proposes a ball bearing guardrail that is easy to assemble, as detailed below:

[0034] For reference Figure 1 This application mainly consists of an outer frame 1, an inner recessed frame 2 provided on the outer frame 1, a slide rail 21 provided on the inner recessed frame 2, a connector 3 provided in the slide rail 21, a ball bearing 4 connected to the inner recessed frame 2 through the connector 3, and a positioning block 5 for limiting the connector 3; through the mutual cooperation between the structures, the device is more convenient to assemble and disassemble. Furthermore, when the ball bearing 4 is worn out and cannot be used again, the damaged ball bearing 4 can be removed and replaced.

[0035] For reference Figure 1 and Figure 2 The outer frame 1 is a square plate with a T-shaped cutout in the middle. The T-shape is set on the square plate in a state of being rotated 90 degrees counterclockwise, thus forming the shape of the outer frame 1.

[0036] For referenceFigure 1 and Figure 3 The recessed frame 2 is U-shaped, rotated 90 degrees clockwise, and fits the T-shaped cutout of the outer frame 1. It is inserted into the outer frame 1. Due to the U-shape of the recessed frame 2, there is still a cutout area in the middle, which is the area for installing the ball bearing 4. The edge of the ball bearing 4 is set to extend beyond the edge of the outer frame 1 towards the outside.

[0037] To facilitate the connection and positioning of the outer frame 1 after it is positioned inside the recessed frame 2, mounting holes 6 are provided on the front and back of the outer frame 1 and the recessed frame 2 respectively. By inserting screws into the mounting holes 6, the recessed frame 2 is stably connected to the outer frame 1.

[0038] Furthermore, the middle of the recessed frame 2 is recessed inward, that is, the middle position of the U shape. A slide 21 is provided on both sides of the recess. The connector 3 is set in the slide 21 and connected to the ball 4. The ball 4 is set in the recessed frame 2. It should be noted that each end of the ball 4 is connected to a connector 3 and connected to the slide 21 on both sides.

[0039] For reference Figure 1 and Figure 4 To avoid requiring larger ball bearings 4 due to excessively large outer frame 1 and inner recessed frame 2, and to prevent the ball bearings 4 from being positioned in the connection gap between the outer frame 1 and inner recessed frame 2, multiple connectors 3 are used, each connecting to one ball bearing 4. This ensures that each ball bearing 4 is individually positioned, facilitating the removal of a single faulty ball bearing 4 during maintenance. Furthermore, to further eliminate the need to consider connection gaps during installation, the connector 3 includes a roller 31 and a support shaft 32. The roller 31 is located at the midpoint of both ends of the ball bearing 4, providing support. One end of the shaft 32 is detachably mounted on the roller 31, and the other end is connected to the slide rail 21 and can move along the direction of the slide rail 21. The roller 31 is located in the middle of both ends of the ball 4, which makes the ball 4 maintain a rotatable effect. The upper surface of the support shaft 32 only needs to be connected to the end of the roller 31 away from the ball 4 to match the setting of the ball 4. Therefore, the connection between the support shaft 32 and the roller 31 makes the installation of the ball 4 convenient and reduces the limitations of the installation of the ball 4. Relatively speaking, it is not necessary to consider whether the connection gap between the outer frame 1 and the inner recessed frame 2 will affect the ball 4.

[0040] For reference Figure 1 and Figures 4-5Each ball bearing 4 is individually connected to a connector 3 for easy subsequent installation. Each ball bearing 4 is connected to a roller 31 and a support shaft 32 at one end. Furthermore, the number of ball bearings 4 corresponds to the number of support shafts 32 connected to the slide rail 21 at one end. To prevent the support shafts 32 from wobbling when working within the slide rail 21, three types of support shafts 32 are provided: A-shaped blocks 321, B-shaped blocks 322, and C-shaped blocks 323. Multiple B-shaped blocks 322 are provided and are flat. The blocks are connected in a row-to-row, interlocking manner to reduce the frequency of shaking. Each block has one A-shaped block 321 and one C-shaped block 323, which are respectively fitted to both ends of multiple connected B-shaped blocks 322. One side of the B-shaped block 322 protrudes outward, and the other side is recessed inward. One side of the A-shaped block 321 is recessed inward, fitting with the outward protruding part of the B-shaped block 322. One side of the C-shaped block 323 protrudes outward, fitting with the inward recessed part of the B-shaped block 322. The total number of A-shaped blocks 321, B-shaped blocks 322, and C-shaped blocks 323 matches the total number of balls 4.

[0041] In view of the above, the ends of the mounting shaft A-shaped block 321 and C-shaped block 323 that are far away from B-shaped block 322 are flat, which better promotes the positioning block 5 to fit against its surface for clamping and fixing.

[0042] For reference Figure 6 The middle part of the slide 21 is protruded outward, and the distance between the bottom of both ends and the bottom of the recessed frame 2 is smaller than the distance between the bottom of the middle protrusion and the bottom of the recessed frame 2, thus causing the two ends to form an L-shaped notch; the positioning block 5 is set to adapt to the shape of the notch, and is set to L-shape. It is fitted and installed at both ends of the slide 21. After the positioning block 5 is connected, it is flush with the surface of the outer frame 1, filling the gap and making the contact surface between the positioning block 5 and the slide 21 more stable after connection.

[0043] For reference Figure 1 The positioning block 5 and the recessed frame 2 are both provided with positioning holes 7. The positioning holes 7 on the positioning block 5 and the recessed frame 2 correspond to each other, so the positioning block 5 can be connected and fixed by bolts passing through the recessed frame 2.

[0044] In view of the above, when setting up ball bearing guardrails, it is not necessary for all the balls 4 to be of the same size. For aesthetic reasons, balls 4 of different diameters can be used. It is only necessary that the outer edges of all balls 4 are flush. At this time, the support shafts 32 of different lengths can be replaced.

[0045] In this invention, the working steps of the device are as follows:

[0046] 1. First, install rollers 31 on the bottom of multiple balls 4, and connect rollers 31 of appropriate size under each roller 31;

[0047] 2. Then, first fix one of the positioning blocks 5 to one side of the slide 21, and then set the ball 4 with the C-shaped block 323 along the slide 21 and press it against the positioning block 5 after positioning.

[0048] 3. Then, connect all the ball bearings 4 with B-shaped blocks 322 to the slide rail 21 in sequence. A B-shaped block 322 close to the C-shaped block 323 forms a snap-fit ​​between the two. Then connect the ball bearings 4 with A-shaped blocks 321 to it, and fix it at the other end by another positioning block 5.

[0049] 4. Finally, insert the recessed frame 2 into the outer frame 1, and connect the corresponding mounting holes 6 with bolts to form a fixed structure.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
