Technical Field

[0001] The utility model relates to the technical field of shared bicycle production and processing, in particular to a locking nut installation mechanism. Background Technique

[0002] With the improvement of the national living standard, the number of private cars has been increasing, resulting in difficult parking. While shared bicycles only need half a square meter of space to park and lock, effectively solving the parking problem. In addition, shared bicycles are affordable, without the need for fuel or charging fees, reducing the travel cost. At the same time, cycling can also keep fit and is low-carbon and environmentally friendly, which is a convenient, economical and healthy way of traveling.

[0003] At present, in the production and processing of shared bicycles, the bicycle basket is fixedly installed on the bicycle frame through bolts. Therefore, it is necessary to first fixedly install the locking nuts on the injection-molded basket, and then assemble the basket and the frame through bolts. The current method of fixing the nuts is to manually use tools to position the nuts into the reserved installation holes on the basket one by one, with low production efficiency.

[0004] Therefore, the utility model proposes a locking nut installation mechanism to solve the above problems. Content of the Utility Model

[0005] According to the above existing technical problems, the utility model provides a locking nut installation mechanism, which is characterized by including a bottom plate, a support rod, a top plate, a downward pressing cylinder, a downward pressing plate, a downward pressing column, a guiding column, and a limiting component. The two ends of the bottom plate are respectively welded and fixed with support rods. The upper ends of the support rods are fixedly connected with the top plate through bolts. The top plate is provided with a downward pressing cylinder, and the telescopic end of the downward pressing cylinder is connected with the downward pressing plate. The guiding holes arranged at both ends of the downward pressing plate are penetrated and connected by guiding columns. The bottom of the guiding column is connected to the limiting component, and the limiting component is installed on the bottom plate.

[0006] The limiting component is composed of a positioning plate and positioning blocks. The positioning plate is fixedly installed on the bottom plate, and two positioning blocks are fixedly connected to the positioning plate through screws.

[0007] The bottom end of the guiding column is fixedly connected to the positioning plate, and the upper end of the guiding column is connected to the top plate.

[0008] The positioning blocks are arranged in an "L" shape, and the upper ends of the opposite surfaces of the two positioning blocks are arranged as arc surfaces.

[0009] Specifically, rubber pads are arranged on the arc surfaces of the positioning blocks to protect the side surface of the basket when positioning the basket.

[0010] Specifically, the position of the pressing column corresponds to the position of the reserved installation hole on the basket, and the cross-section of the reserved installation hole on the basket is set as a rhombus structure. The diameter of the pressing column is smaller than the diameter of the reserved installation hole, and the diameter of the locking nut is slightly larger than the diameter of the reserved installation hole. During the pressing process, the locking nut is pressed into the reserved installation hole.

[0011] Advantages of the utility model:

[0012] When installing the locking nut of the utility model, first place the basket between the two positioning blocks of the positioning plate. The two sides and the rear side of the basket are in contact with the positioning blocks, which completes the positioning of the basket. Then place the locking nut on the reserved installation hole on the basket, start the pressing cylinder, and the pressing cylinder quickly pushes the lower pressing plate downward. The pressing column corresponding to each reserved installation hole presses the locking nut into the reserved installation hole on the basket, which completes the installation of the locking nut.

[0021] Embodiment 1

[0022] As shown in the figure, support rods 2 are welded and fixed at both ends of the bottom plate 1. The upper ends of the support rods 2 are fixedly connected to the top plate 3 by bolts. A downward pressure cylinder 4 is installed on the top plate 3. The telescopic end of the downward pressure cylinder 4 is connected to the downward pressure plate 5. The guide holes provided at both ends of the downward pressure plate 5 are penetrated and connected by guide posts 7. The upper ends of the guide posts 7 are connected to the top plate 3, and the bottom ends of the guide posts 7 are fixedly connected to the positioning plate 81. The positioning plate 81 is fixedly installed on the bottom plate 1. Two positioning blocks 82 are fixedly connected to the positioning plate 81 by screws 821.

[0023] As Figure 1 and 2 shown, the two positioning blocks 82 are arranged in an "L" shape, and the upper ends of the opposite faces of the two positioning blocks 82 are arranged as arc surfaces, and rubber pads 83 are arranged on the arc surfaces, which play a protective role in the side of the basket when positioning the basket 100.

[0024] Embodiment 2

[0025] When using the present utility model, when installing the locking nut 102, first place the basket 100 between the two positioning blocks 82 of the positioning plate 81. The two sides of the basket 100 are in contact with the arc-shaped surfaces of the positioning blocks 82, and push the basket 100 inward until the rear side surfaces of the basket 100 are in contact with the transverse plates of the positioning blocks 82. At this time, the rear side surface and the two side surfaces of the basket 100 are in contact with the positioning blocks 82, that is, the positioning of the basket 100 is completed. Then place the locking nut 102 on the reserved installation hole 101 on the basket 100. Start the downward pressing cylinder 4, and the downward pressing cylinder 4 quickly pushes the lower pressing plate 5 downward. The downward pressing columns 6 corresponding to the positions of each reserved installation hole 101 press the locking nut 102 into the reserved installation hole 101 of the basket 100, that is, the installation of the locking nut 102 is completed. The mechanical processing has high efficiency, convenient operation and saves labor.

[0026] It should be noted that the position of each downward pressing column 6 corresponds to the position of the reserved installation hole 101 on the basket 100. As Figure 4 shown, the cross-section of the reserved installation hole 101 of the basket 100 is set as a diamond structure. The diameter of the downward pressing column 6 is smaller than the diameter of the reserved installation hole 101, and the diameter of the locking nut 102 is slightly larger than the diameter of the reserved installation hole 101. Therefore, placing the locking nut 102 on the reserved installation hole 101 will not enter the reserved installation hole 101 by itself. During the downward pressing process of the downward pressing column 6, the locking nut 102 will be squeezed and pressed into the reserved installation hole 101. The reserved installation hole 101 is a reserved installation hole in the previous process of manufacturing the basket 100. And the basket 100 is made of plastic material and has certain elasticity. Therefore, the locking nut 102 can be squeezed into the reserved installation hole 101.

[0027] It should be noted that the downward pressing cylinder 4 is connected to the pneumatic source and the control switch to control the operation of the downward pressing cylinder 4. This is a control means of the prior art. Therefore, the pneumatic source and the control switch are not shown in this application and are not described in detail.
