As shown in fig. 2 to 4, the present embodiment relates to a display adjusting base, which includes a bracket 1 connected to a rack, and a fixing plate 2 connected to the bracket 1 through an adjusting mechanism. The adjusting mechanism comprises an adjusting link rod 3 and a plurality of groups of elastic locking assemblies 4, and the upper end part of the bracket 1 and the fixing plate 2 are respectively connected with the two end parts of the adjusting link rod 3 through at least one group of elastic locking assemblies 4. Based on the elastic locking assembly 4, the adjusting link 3 can be rotated or locked along the hinged end thereof with respect to the upper end portion of the bracket 1, and the fixing plate 2 can be rotated or locked along the hinged end thereof with respect to the adjusting link 3. The support 1 in the display adjusting seat is used for being connected to a frame of the body-building equipment, and the fixing plate 2 is used for fixedly mounting the display. Different from the prior art, the fixing plate 2 and the bracket 1 are connected by means of an adjusting mechanism in the scheme, the fixing plate 2 and the display thereon can rotate relative to the adjusting link 3 to perform first-stage adjustment, and the adjusting link 3 can also rotate relative to the bracket 1 to perform second-stage adjustment. Through the two-stage adjustment, the display can be adjusted in a larger range, and users with different body types and different exercise habits can adjust the height and the angle of the display according to the visual field positions of the users when using the fitness equipment, so that the fitness is wider. On the basis, whether the two parts connected with each other can be controlled to rotate or be locked with each other based on the elastic locking assembly 4, so that the display adjusting seat can be in a positioning state when not adjusted, namely, the display is locked after being highly positioned, and the problems of unstable and loose display position are avoided.

Thus, the position of the fixing block 41 moving axially can control whether the adjusting link 3 and the bracket 1 are locked or unlocked; the adjustment between the adjusting link 3 and the fixing plate 2 is performed in the same manner. The elastic member 42 is a spring as shown in the figure, a deformation end of the elastic member 42 axially acts on an inner end side of the fixed block 41, and the button 43 abuts against an outer end side of the fixed block 41. When the fixing block 41 is only subjected to the elastic force of the elastic member 42, the adjusting link 3 and the bracket 1, or the adjusting link 3 and the fixing plate 2 are locked by the fixing block 41. When an external force is applied to the button 43 to drive the fixing block 41 to move axially, the adjusting link 3 and the bracket 1, or the adjusting link 3 and the fixing plate 2, can rotate relative to each other. On the basis of the above solution, the elastic locking assembly 4 further includes an elastic member 42 and a button 43, and the external force applied to the button 43 and the elastic force of the elastic member 42 are used to control the axial position of the fixing block 41. When no external force is applied, the fixing block 41 locks the adjusting link 3 and the bracket 1, or the adjusting link 3 and the fixing plate 2, under the elastic support of the elastic member 42. While when an external force is applied to the button 43, unlocking and rotational adjustment can be achieved.

When at least part of the fixing block 41 extends into the second positioning slot 32, the adjusting link 3 is locked with the bracket 1. When an external force is applied to the button 43 to drive the fixing block 41 to move axially out of the second positioning slot 32, the adjusting link 3 and the bracket 1 can rotate relative to each other. In the scheme, the first positioning groove 31 of the adjusting link 3 and the fixed block 41 are always positioned circumferentially but can move axially relative to each other, and when at least part of the fixed block 41 extends into the second positioning groove 32, the adjusting link 3 is locked with the bracket 1. When the fixing block 41 exits from the second positioning slot 32, the adjusting link 3 and the bracket 1 can rotate relative to each other, and because the fixing block 41 is limited to be circumferentially symmetrical along the center point thereof in the above scheme, the adjusting link 3 can still be circumferentially positioned with the second positioning slot 32 after rotating for a certain angle.

Specifically, as shown in fig. 2, the second end of the adjusting link 3 is provided with a second insertion groove 34, the rear end of the fixed plate 2 is provided with a hinge block 21, and the hinge block 21 is inserted into the second insertion groove 34. The side wall of the hinged block 21 is provided with a first positioning groove 31, the side wall of the second embedded groove 34 is provided with a second positioning groove 32 corresponding to the first positioning groove 31, and a shaft hole 33 is arranged in the second positioning groove 32. The fixing block 41 is located in the first positioning groove 31, is circumferentially positioned with the first positioning groove 31, and can axially move relatively, the elastic component 42 is located in the first positioning groove 31 in the fixing block 41, and the button 43 is arranged in the shaft hole 33 in a penetrating manner. When at least part of the fixing block 41 extends into the second positioning slot 32, the adjusting link 3 is locked with the fixing plate 2. When an external force is applied to the button 43 to drive the fixing block 41 to move axially out of the second positioning groove 32, the adjusting link 3 and the fixing plate 2 can rotate relative to each other. The engagement structure between the adjustment link 3 and the fixing plate 2 is described in the embodiment, and the embodiment is identical to the engagement structure between the adjustment link 3 and the bracket 1, and the engagement manner of the first positioning groove 31, the second positioning groove 32 and the fixing block 41 can be referred to in the above description.

In the above technical solution, the fixing block 41 is always circumferentially positioned with the first positioning groove 31, but can axially move to enter or exit the second positioning groove 32, and when it exits the second positioning groove 32, the two components can rotate relative to each other. The second positioning groove 32 and the fixing block 41 can still be butted and positioned after rotating relatively, and the fixing block 41 is inevitably required to be symmetrical along the circumferential direction of the central point thereof. In this case, it is more preferable that the fixing block 41 is a fixed gear, and the first positioning groove 31 and the second positioning groove 32 are both tooth-shaped grooves adapted to an outer profile of the fixed gear. Adopt fixed gear and the mode of tooth-shaped groove complex, its minimum turned angle requirement is lower, and minimum turned angle only need be for the contained angle between two adjacent tooth portions of fixed gear can, so be convenient for realize the quick location of fixed gear and second constant head tank 32. In addition, the shaft hole 33 is a circular hole, the shaft hole 33 is located at the center of the second positioning groove 32, and the circumferential section of the key is circular.
