Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, in the adaptive slider disclosed in the present embodiment, the slider 1 includes a first support 11, a second support 12, an elastic member 13, a connecting member 14, and a rolling member 15.

An elastic part 13 is arranged on the connecting part 14 or between the first support 11 and the second support 12. The distance between the first support 11 and the second support 12 can be adjusted through the elastic piece 13 and/or the connecting piece 14, and the first support 11 and/or the second support 12 can rotate by taking the connecting piece 14 as an axis.

The first support 11 and the second support 12 are integrally installed through the connecting piece 14, so that the first support 11, the second support 12 and the rolling piece 15 slide simultaneously. Rolling members 15 are respectively installed on both sides of the first support 11 and the second support 12, and the rolling members 15 are used for contacting with the sliding surface 21 to realize the integral movement of the sliding block 1.

The rolling members 15 may be rollers, steel balls or bearings. In this embodiment, a bearing is used. The bearing is provided with 4 sets of bearings which are respectively arranged on two sides of the first support 11 and the second support 12. Because the bearing needs to be in contact with the sliding surface 21, the outermost sides of the 4 sets of bearings structurally protrude out of the first support 11 and the second support 12.

In this embodiment, the first support 11 and the second support 12 are symmetrically arranged, and both sides are sloping plates. The structural strength of the first support 11 and the second support 12 can be enhanced by the inclined plate, and the space for installing the rolling members 15 is increased.

The inclined plates on the same side of the first support 11 and the second support 12 incline outwards, namely the two inclined plates on the same side are opposite to each other to form a flaring shape. The inclined plate is arranged, so that an included angle is formed between the rolling parts 15 on the same side of the first support 11 and the second support 12, and the left side, the right side, the upper side and the lower side of the sliding block 1 can be limited.

Besides, the first support 11 and the second support 12 can be integrally manufactured by adopting an integral structure such as an arc plate and a bent plate without arranging an inclined plate, and can also realize the self-adaptive adjustment and the limit of the sliding block 1 and the sliding surface. Even when the first support 11 and the second support 12 are of flat plate structures, the self-adaptive adjustment, the limiting function and the effect of the sliding block 1 can be realized by combining the installation position and the angle adjustment of the rolling element 15.

The rolling members 15 are mounted on the opposite surfaces of the two swash plates while shifting the mounting positions in this embodiment. So as to save the installation space of the rolling element 15 and make the structure of the sliding block 1 more compact. However, the mounting position of the rolling elements 15 may not be offset, but can also be realized in a completely symmetrical position.

The connecting member 14 may be engaged with a nut using a screw or a bolt. In this embodiment, a screw and a nut are used. The first support 11 and the second support 12 are provided with mounting holes matched with the connecting piece 14, and a gap is arranged between the mounting holes and the connecting piece 14. When sliding, the first support 11 and the second support 12 can rotate relatively around the screw to drive the rolling members 15 to perform adaptive adjustment until all the rolling members 15 contact the sliding surface 21.

The elastic member 13 may be a spring, a leaf spring or a leaf spring. In this embodiment, a reed is used. The leaf spring is also called a leaf spring. The reed is sleeved on the connecting piece 14 between the first support 11 and the second support 12, so that a larger adjusting distance can be realized between the first support 11 and the second support 12, the structure of the sliding block 1 is more compact, and the self-adaptive adjusting performance of the sliding block 1 is ensured.

Specifically, according to the self-adaptive sliding block of the embodiment, through improving the structure, the elastic element 13 is additionally arranged between the first support 11 and the second support 12 on the sliding block 1, and before installation, the connecting element 14 is fastened to reduce the distance between the first support 11 and the second support 12, and at this time, the sliding block 1 can be easily put into the sliding groove of the sliding rail 2; then the connecting piece 14 is loosened, namely the nut of the connecting piece 14 rotates back from the tightened state, the first support 11 and the second support 12 move outwards under the pushing of the elastic piece 13, so that the distance between the first support 11 and the second support 12 is increased, the rolling piece 15 is driven to move outwards, and the left position, the right position and the up-down position of the sliding block 1 are all restrained in the sliding groove. Therefore, even if the sliding groove of the sliding rail 2 is not completely straight or the sliding surface has errors, the first support 11, the second support 12 and the rolling element 15 can be automatically adjusted in real time under the action of the elastic element 13, so that the rolling element 15 is completely contacted with the sliding surface of the sliding rail 2.

The rolling elements 15 on the sliding block 1 are arranged in more than 4 sets, so that the sliding stability of the sliding block 1 can be enhanced; a certain gap is left between the mounting hole and the connecting piece 14, so that the first support 11 and the second support 12 rotate by taking the connecting piece 14 as an axis, and the effect of self-adapting to a guide rail sliding groove or a sliding surface is achieved.

In addition, the bearings may also be increased by multiples of 2, i.e., 6, 8, 10, 12, etc.

The connecting piece 14 adopts a screw and nut component, 2 sets of the connecting piece are arranged and are arranged at the middle part of the sliding block 1 at intervals. The 2-set connecting piece 14 can enable the connection between the first support 11 and the second support 12 to be more stable, and a better overall sliding effect is formed.

Because certain gaps are reserved between the 2 sets of connecting pieces 14 and the mounting holes on the first support 11 and the second support 12, the embodiment has the effect of the first embodiment, and the rotating ranges of the first support 11 and the second support 12 can be limited by utilizing the gaps between the 2 sets of mounting holes and the connecting pieces 14, namely the limit of the self-adaptive adjusting range is realized, and the sliding performance and the accuracy of the sliding block 1 are improved.
