Description

Technical Field

[0001] The utility model relates to the technical field of treadmills, in particular to a supporting chassis of a treadmill and the treadmill. Background Art

[0002] As attached Figure 5 As shown, a support base frame for a treadmill in the prior art includes two oppositely arranged side tubes 1' and two cross bars 2' connected between the two side tubes 1'. In this structure, the two cross bars 2' are respectively abutted between the front end positions and the middle inner positions of the two side tubes 1', and are fixedly connected by welding. In this way, since the two ends of the cross bars 2' are only abutted against the inner sides of the two side tubes 1' and then fixed by welding, the overall firmness and stability of the support base frame are poor, and the treadmill cannot be stably supported. As a result, after the main structure of the treadmill is assembled with the support base frame, the treadmill body may sway left and right under some working conditions where the treadmill handrails are used, affecting the user experience of the treadmill and even causing safety hazards in the use of the treadmill. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a support base for a treadmill, which mainly solves the technical problem that the support base of the prior treadmill has poor overall firmness and stability.

[0004] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0005] A support base for a treadmill includes two oppositely arranged side tubes and at least two first and second cross bars respectively welded between the front ends and the middle portions of the two side tubes. The ends of the second cross bars penetrate the inner and outer edges of the two side tubes and are welded and fixed at the interpenetrating connections between the inner and outer edges of the side tubes and the ends of the second cross bars. The ends of the first cross bars penetrate at least the front ends of the inner edges of the two side tubes and are welded and fixed at least at the interpenetrating connections between the inner edges of the side tubes and the ends of the first cross bars.

[0006] Furthermore, corresponding central inner openings and central outer openings are opened at the middle positions of the inner and outer edges of the two side tubes, and the ends of the second crossbar pass through the central inner openings and the central outer openings and are connected with the side tubes.

[0007] Furthermore, the end of the first cross bar passes through the front ends of the inner sides of the two side tubes and abuts against the inner walls of the corresponding outer sides, and is welded and fixed at the interpenetrating connection between the first cross bar and the inner sides of the side tubes.

[0008] Furthermore, a front end inner opening is opened at the front end position of the inner side edge of the two side tubes, and the end of the first cross bar passes through the front end inner opening and abuts against the inner wall of the corresponding outer side edge.

[0009] Furthermore, the end of the first cross bar passes through the front ends of the inner and outer sides of the two side tubes, and is welded and fixed at the interpenetrating connection between the inner and outer sides of the side tubes and the end of the first cross bar.

[0010] Furthermore, a third cross bar is included, and both ends of the third cross bar are respectively connected between the rear ends of the two side tubes.

[0011] Furthermore, two ends of the third crossbar are respectively in contact with the rear ends of the inner sides of the two side tubes and are welded and fixed together.

[0012] Furthermore, foot pads are installed at the front and rear ends of the bottom of the two side tubes.

[0013] Furthermore, rollers are provided at the rear ends of the two side tubes.

[0014] Based on the same inventive concept, the present invention also provides a treadmill, comprising any one of the above-mentioned support base frames of the treadmill.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] In the support base frame and treadmill described in the utility model, a first cross bar and a second cross bar are respectively provided between the front end and the middle position of the two side tubes, and the ends of the second cross bar pass through the inner side edges and the outer side edges of the two side tubes, and are welded and fixed at the interlaced connections between the inner and outer edges of the side tubes and the ends of the second cross bar. The plug-in connection formed by the cross bar passing through the side tubes is combined with the connection structure of the inner and outer sides to further improve the connection firmness between the side tubes and the second cross bar. At the same time, the ends of the first cross bar at least pass through the front ends of the inner side edges of the two side tubes, and are welded and fixed at least at the interlaced connections between the inner edges of the side tubes and the ends of the first cross bar. Compared with the existing connection structure in which the cross bars are only welded to the inner sides of the side tubes, the mutual cooperation between the first cross bar and the second cross bar can greatly improve the overall firmness and stability of the support base.

[0026] Please refer to the attached Figure 1 To the attached Figure 4 An embodiment of the present invention provides a support base for a treadmill, comprising two oppositely arranged side tubes 1 and at least two first cross bars 2 and second cross bars 3 respectively welded between the front end and the middle of the two side tubes 1, the ends of the second cross bars 3 pass through the inner side edges 11 and the outer side edges 12 of the two side tubes 1, and are welded and fixed at the interpenetrating connection between the inner side edges 11 and the outer side edges 12 of the side tubes 1 and the ends of the second cross bars 3, and the ends of the first cross bars 2 pass through at least the front end of the inner side edges 11 of the two side tubes 1, and are welded and fixed at least at the interpenetrating connection between the inner side edges 11 of the side tubes 1 and the ends of the first cross bars 2. It can be understood that in this embodiment, a first cross bar 2 and a second cross bar 3 are respectively provided between the front end and the middle position of the two side tubes 1, and the ends of the second cross bar 3 pass through the inner side edges 11 and the outer side edges 12 of the two side tubes 1, and are welded and fixed at the interpenetrating connection between the inner side edges 11 and the outer side edges 12 of the side tubes 1 and the ends of the second cross bar 3. The plug-in connection formed by the cross bar passing through the side tubes is combined with the inner and outer welded fixed connection structure to further improve the connection firmness between the side tubes 1 and the second cross bar 3. At the same time, the ends of the first cross bar 2 at least pass through the front ends of the inner side edges 11 of the two side tubes 1, and are welded and fixed at least at the interpenetrating connection between the inner side edges 11 of the side tubes 1 and the ends of the first cross bar 2. Compared with the existing connection structure in which the cross bars are only welded to the inner sides of the side tubes, the mutual cooperation between the first cross bar 2 and the second cross bar 3 can greatly improve the overall firmness and stability of the support frame.

[0027] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, corresponding central inner openings 13 and central outer openings 14 are provided at the middle positions of the inner side edges 11 and the outer side edges 12 of the two side tubes 1, and the ends of the second crossbar 3 pass through the central inner openings 13 and the central outer openings 14 and are connected to the side tubes 1.

[0028] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the side tubes 1 are preferably square hollow tube structures, and the first crossbar 2, second crossbar 3, and third crossbar 4 are all square rod structures. This allows the support frame formed by the side tubes 1 and the first crossbar 2, second crossbar 3, and third crossbar 4 to be placed more stably.

[0029] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the end of the first crossbar 2 passes through the front end of the inner side edge 11 of the two side tubes 1 and abuts against the inner wall of the corresponding outer side edge 12, and is welded and fixed at the interpenetrating connection between the first crossbar 2 and the inner side edge 11 of the side tube 1. Preferably, a front end inner opening 15 is opened at the front end of the inner side edge 11 of the two side tubes 1, and the end of the first crossbar 2 passes through the front end inner opening 15 and abuts against the inner wall of the corresponding outer side edge 12. In this embodiment, by opening the front end inner opening 15 at the front end of the inner side edge 11 of the two side tubes 1, and the end of the first crossbar 2 only passes through the front end inner opening 15 and abuts against the inner wall of the corresponding outer side edge 12, on the one hand, the connection stability between the crossbar and the side tube can be effectively improved. On the other hand, under the premise of ensuring sufficient connection strength and stability between the front ends of the two side tubes 1, it is not necessary to machine openings on both the inner and outer sides of the front end of the side tube 1, which helps to reduce its processing difficulty and improve processing efficiency. However, those skilled in the art will appreciate that, in other embodiments, to further enhance the overall stability of the support frame, the ends of the first crossbar 2 may be passed through the front ends of the inner and outer sides 11, 12 of the side tubes 1, and welded to the inner and outer sides 11, 12 of the side tubes 1 and the ends of the first crossbar 2. In this manner, both the first crossbar 2 and the second crossbar 3 are welded to the inner and outer sides 11, 12 of the side tubes 1, greatly enhancing the stability of their connection.

[0030] Please refer to the attached Figure 1 To the attached Figure 3In one preferred embodiment, a third crossbar 4 is further included, with both ends of the third crossbar 4 connected between the rear ends of the two side tubes 1. Specifically, both ends of the third crossbar 4 abut against the rear ends of the inner side edges 11 of the two side tubes 1 and are welded together. Based on the force conditions at the rear end of the support frame, the two ends of the third crossbar 4 are cleverly arranged to abut against the rear ends of the inner side edges 11 of the two side tubes 1 and are welded together. This can reduce the difficulty of processing and improve processing efficiency, and enhance the strength and stability of the connection between the rear ends of the two side tubes 1.

[0031] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, foot pads 5 are installed at the front and rear ends of the bottom of the two side tubes 1. Preferably, rollers 6 are provided at the rear ends of the two side tubes 1.

[0032] Please refer to the attached Figure 1 To the attached Figure 4 , a connecting piece for fixedly connecting to the column of the treadmill is provided near the front end of the two side tubes 1 of the supporting frame (specifically, the area between the connection positions of the side tube 1 and the first cross bar 2 and the second cross bar 3). In this embodiment, since the two ends of the second cross bar 3 are connected and welded to the inner side edges 11 and the outer side edges 12 of the two side tubes 1, and the two ends of the first cross bar 2 are at least connected and welded to the inner side edges of the two side tubes 1, the column of the treadmill can be connected to a relatively stable position in the supporting frame structure, which greatly ensures the stability of the treadmill during use and greatly reduces the possibility of the treadmill shaking during use.

[0033] Please refer to the attached Figure 4 An embodiment of the present invention further provides a treadmill, comprising the support base of the treadmill of any of the above embodiments.
