[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0029] See Figures 1-7 A treadmill frame assembly structure includes a treadmill frame 1, which has a plurality of first receiving slots 2 and a plurality of second receiving slots 3.

[0030] As one option, at least four first receiving slots 2 are provided, respectively arranged at: the left front position of the treadmill frame 1, the right front position of the treadmill frame 1, the left rear position of the treadmill frame 1, and the right rear position of the treadmill frame 1, such as... Figure 1 , Figure 3 As shown.

[0031] As one option, at least three sets of second receiving slots 3 are provided, respectively arranged at the front end of the treadmill frame 1, the middle of the treadmill frame 1 and the rear end of the treadmill body 1. Each set includes two second receiving slots 3, which are respectively arranged on the left side strip 11 and the right side strip 12 of the treadmill frame 1, and their positions correspond to each other, such as being on the same horizontal line.

[0032] Specifically, corresponding second receiving slots 3 are arranged at the front, middle, and rear ends of the left side strip 11 of the treadmill frame 1, and corresponding second receiving slots 3 are arranged at the front, middle, and rear ends of the right side strip 12 of the treadmill frame 1. The two second receiving slots 3 located at the same end (e.g., the two second receiving slots located at the front ends of the left and right side strips are located at the same end) correspond one-to-one. Figure 1 , Figure 3 As shown.

[0033] In this embodiment, the first receiving groove 2 is fitted with a matching connector 4. The connector 4 is used to install the roller. Specifically, the connectors 4 arranged in the two first receiving grooves 2 at the front end of the treadmill frame 1 are used to install the two ends of the front roller, and the connectors 4 arranged in the two first receiving grooves 2 at the rear end of the treadmill frame 1 are used to install the two ends of the rear roller.

[0034] In this embodiment, a first clearance opening 21 for the roller end to pass through is provided on the inner sidewall of the first receiving groove 2, and a second clearance opening 22 for avoiding fasteners is provided on the front and / or rear sidewalls of the first receiving groove 2. Figure 4 As shown.

[0035] Correspondingly, such as Figure 7 As shown, the connector 4 includes a main body portion 41 arranged on the bottom surface of the first receiving groove 2 and a side body portion 42 formed by bending the two ends of the main body portion 41 upwards. The side body portion 42 is provided with a mating hole 43 that cooperates with the fastener and corresponds to the second clearance opening 22.

[0036] The state of connector 4 when it is assembled in the first receiving groove 2 is as follows Figure 2 As shown, after installation, the two side body parts 42 abut against the front and rear side walls of the first receiving groove 2, respectively, and the mating holes 43 on the two side body parts 42 correspond to the corresponding second clearance openings 22, so that when the fastener is assembled on the mating hole 43, the second clearance opening 22 provides the space required for its movement, and the fastener is used to connect the end of the roller to support the roller.

[0037] The main body 41 rests against the bottom surface of the first receiving groove 2. To further improve the stability of the connector 4 installation, the main body 41 of the connector 4 is provided with several holes 44, such as two holes distributed on the left and right sides, and then fixed to the treadmill frame 1 by fasteners.

[0038] The second receiving groove 3 is used to embed the reinforcing rod 5 that is compatible with it. The two second receiving grooves 3 located at the same end are used to embed the two ends of the reinforcing rod 5 respectively. The state of the reinforcing rod 5 after installation is as follows. Figure 1 As shown.

[0039] As one option, reinforcing rod 5 is made of metal square tubing.

[0040] The installation of the reinforcing bar 5 helps to connect the left side bar 11 and the right side bar 12 of the treadmill frame 1 into a whole, thereby enhancing the rigidity of the treadmill frame 1.

[0041] In this embodiment, a positioning hole 31 is provided on the bottom surface of the second receiving groove 3, and a nut 32 is disposed in the positioning hole 31. For example, the shape of the positioning hole 31 is a hexagon that matches the shape of the nut 32. The nut 32 is embedded in the positioning hole 31. At the same time, several support feet 33 are installed at the bottom of the treadmill frame 1. The upper end of the support foot 33 is threaded onto the nut 32. Figure 6 As shown, a support foot 33 is provided at the corresponding position of each second receiving slot 3.

[0042] As one option, the end of the reinforcing rod 5 is fitted with a fastener that is threaded into the nut 32. In this way, not only can the reinforcing rod 5 be positioned, but the nut 32 can also be positioned longitudinally to prevent the nut 32 from falling out of the positioning hole 31. Similarly, the support foot 33 is also locked.

[0043] Of course, the nut 32 can also be directly fixed to the positioning hole 31 by means of adhesive or welding. Regardless of whether the reinforcing rod 5 is fixed to the treadmill frame 1, or whether the reinforcing rod 5 is fixed to the treadmill frame 1 at other positions that do not correspond to the nut 32, the nut 32 will still not fall off from the positioning hole 31.

[0044] As one option, at least three reinforcing bars 5 are provided, respectively located at the front, middle and rear ends of the treadmill frame 1.

[0045] As one option, the treadmill frame 1 is integrally formed, and the first receiving groove 2 and the second receiving groove 3 are both formed during the integral forming of the treadmill frame 1.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
