Description

Technical Field

[0001] This utility model belongs to the field of treadmill technology, and in particular relates to a two-section treadmill connection structure. Background Technology

[0002] Traditional treadmills typically use a one-piece running board design, meaning the entire running area is made of a single, continuous, rigid or slightly flexible board. This design is simple and inexpensive, and is widely used in mainstream treadmills. However, as users' demands for running experience, joint protection, and training effectiveness continue to increase...

[0003] However, the large size of an all-in-one treadmill makes it inconvenient to move, especially in home settings where space is limited. Furthermore, the large size increases logistics costs (such as additional fees for extra-long items), and it is easily damaged during transport. Additionally, the assembly and disassembly processes are complex and inefficient. Therefore, we offer a two-section treadmill connection structure to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a two-section treadmill connection structure. By using the assembly cylinder and tenon structure together, the running platform can be divided into two parts, which facilitates the quick assembly and disassembly of the running platform. Compared with traditional treadmills, the number of parts is reduced and the weight is reduced.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a two-section treadmill connection structure, including a first running platform and a second running platform connected to the end face of the first running platform. Grooves are provided on both the left and right sides of the end face of the first running platform connected to the second running platform. An assembly cylinder is provided inside each groove. Multiple sets of evenly distributed protrusions are fixed on the top surface of the assembly cylinder. Tenon structures that are inserted into the corresponding positions inside the assembly cylinder are fixed on the end face of the second running platform connected to the first running platform.

[0006] The present invention is further configured such that the upper and lower end faces of the tenon structure are provided with recesses at the positions of the corresponding protrusions, and each group of protrusions is inserted into the corresponding recess.

[0007] The present invention is further configured such that a screw hole 2 is provided through the middle position of each tenon structure, and a screw hole 1 is provided through the inner wall of the assembly cylinder at the position corresponding to the screw hole 2, which communicates with the inside of the groove. The screw hole 1 and the screw hole 2 are on the same axis.

[0008] The present invention is further configured such that an assembly groove is provided on the inner side wall of the bottom of the second running platform at the position corresponding to the first screw hole, and a screw rod is provided inside the assembly groove, which spirally passes through the inside of the first screw hole and the second screw hole.

[0009] The present invention is further configured such that a locking bolt is provided on the lower end face of the running platform corresponding to each assembly cylinder, and the running platform is spirally connected to the assembly cylinder through the locking bolt.

[0010] This utility model has the following beneficial effects: This invention aligns two sets of tenon structures on the two end faces of the running platform with the assembly cylinder position on the one end face of the running platform. During the connection process, the second running platform is lifted upwards, so that the second running platform and the first running platform are at a certain tilt angle. The second running platform is then moved towards the first running platform, thereby pushing the tenon structure into the assembly cylinder. Multiple sets of protruding parts on the inner side of the assembly cylinder are then inserted into the concave parts of the tenon structure, thus initially assembling the assembly cylinder and the tenon structure. This allows the running platform to be divided into two parts, facilitating quick assembly and disassembly of the running platform. Compared with traditional treadmills, this invention reduces the number of parts and the weight. Attached Figure Description

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figures 1 to 5 This utility model is a two-section treadmill connection structure. By using the assembly cylinder 103 and the tenon structure 201 together, the running platform is divided into two parts, which facilitates the quick assembly and disassembly of the running platform. Compared with traditional treadmills, the number of parts is reduced and the weight is reduced.

[0020] Specifically, running platform 1 and running platform 2 are connected at the end face of running platform 1. Grooves 101 are provided on both the left and right sides of the end face of running platform 1 where it is connected to running platform 2. Each groove 101 is provided with an assembly cylinder 103. Multiple sets of evenly distributed protrusions 106 are fixed on the top surface of the assembly cylinder 103. Each end face of running platform 2 where it is connected to running platform 1 is fixed with a tenon structure 201 that is inserted into the corresponding position inside the assembly cylinder 103. The upper and lower ends of the tenon structure 201 are provided with recesses 203 at the positions corresponding to the protrusions 106. Each set of protrusions 106 is inserted into the corresponding recesses 203. Locking bolts 105 are provided on the lower end face of running platform 1 at the position corresponding to each assembly cylinder 103. Running platform 1 is spirally connected to the assembly cylinder 103 by locking bolts 105.

[0021] The operation process of this embodiment is as follows: When it is necessary to assemble running platform 1 and running platform 2, the two sets of tenon structures 201 on the end face of running platform 2 are aligned with the assembly cylinder 103 on the end face of running platform 1. During the connection process, running platform 2 is lifted upward so that running platform 2 and running platform 1 are at a certain tilt angle. Running platform 2 is then moved towards running platform 1. As a result, running platform 2 pushes the tenon structure 201 into the assembly cylinder 103, and the multiple sets of protrusions 106 on the inner side of the assembly cylinder 103 are respectively inserted into the concave part 203 of the tenon structure 201. Thus, the assembly cylinder 103 and the tenon structure 201 are initially assembled and combined, thereby dividing the running platform into two parts, which facilitates the quick assembly and disassembly of the running platform. Compared with traditional treadmills, the number of parts is reduced and the weight is reduced.

[0022] Example 2 Please see Figure 3 , Figure 4 and Figure 5Based on Example 1, the screw rod 3 is spirally passed through the screw hole 104 and the screw hole 202 from the inside of the assembly groove 102, thereby improving the tightness of the connection between the tenon structure 201 and the assembly cylinder 103.

[0023] Specifically, screw holes 202 are provided through the middle of the tenon structure 201. Screw holes 104 are provided through the inner wall of the assembly cylinder 103 at the position corresponding to screw holes 202, and are connected to the inside of the groove 101. Screw holes 104 and screw holes 202 are on the same axis. Assembly grooves 102 are provided on the inner side wall of the bottom of the running platform 2 at the position corresponding to screw holes 104. Screw rods 3 are provided inside the assembly grooves 102, which spirally pass through the positions of screw holes 104 and screw holes 202.

[0024] The operation process of this embodiment is as follows: When the tenon structure 201 is inserted into the corresponding position inside the assembly cylinder 103, the screw hole 202 on the side wall of the tenon structure 201 will be directly aligned with the position of the screw hole 104. Therefore, in order to ensure the stable connection between the tenon structure 201 and the assembly cylinder 103, the screw rod 3 can be spirally inserted from the inside of the assembly groove 102 into the screw hole 104 and the screw hole 202, so that the tenon structure 201 is tightly connected and combined with the assembly cylinder 103.
