[0030] The utility model will be explained in further detail in combination with the drawings. These drawings are all simplified schematic views, only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the structure related to the utility model.

[0031] In the description of the utility model, it is understood that the orientation or position relation indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" are based on the orientation or position relation shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as the limitation of the utility model. In addition, the features limited as "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more. ​​

[0032] In the description of the utility model, it needs to explain, unless another explicit provision and limitation, the term "installation", "link", "connection" should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the communication. For ordinary skilled in the art, the above-mentioned term can be understood in the utility model with the concrete meaning of the specific situation.

[0033] Embodiment 1, as shown in Figure 1 And Figure 2 A dummy rail, including the body 1, the body 1 is connected by two connecting bodies to form a whole rectangle, the body 1 is regarded as a whole in the following description. The body 1 has a rolling groove 2 for movably arranging the rolling body. The rolling groove 2 is a plane rolling groove or an arc surface rolling groove, so as to better support the rolling body, and the arc rolling groove is selected in the embodiment. The width of the body 1 gradually decreases from the middle to both sides in the length direction, so that the end of the body 1 forms a tapered gap with the sliding block, facilitating the installation of the dummy rail into the sliding block.

[0034] The body 1 is connected with an integral deformation part, the deformation part has a hollow and closed inner deformation cavity, and a part of the side of the deformation part is connected with the body 1 to form a pressure receiving part 3 in the width direction. The rolling groove 2 directly extrudes the body 1 by assembling the rolling body, and the body 1 is extruded to further extrude the pressure receiving part 3. When the rolling body is installed in the rolling groove 2, the rolling body will generate pressure on the body 1, and the body 1 will be deformed under pressure, and the pressure is also transmitted to the pressure receiving part 3 through the body 1, and the deformation cavity in the deformation part provides sufficient deformation space.

[0035] The cavity region between the outer side of the deformation part and the inner side of the body 1 forms an outer deformation cavity c. Therefore, when the body 1 is extruded by the rolling body, the side of the body 1 also has sufficient deformation space due to the effect of the outer deformation cavity c.

[0036] Under the joint action of the inner deformation cavity and the outer deformation cavity c, the dummy rail has more hollow areas inside, so that the dummy rail has better deformation space, the deformation force is also larger, and the stability of the rolling body is more easily guaranteed, the performance is guaranteed, and the structure is simplified, and the manufacturing process is simplified.

[0037] Preferably, the deformation part includes at least two first parts A and at least one second part B, the first parts A are connected by the second part B to form an integral deformation part. The deformation part is connected inside the body 1, and the deformation part and the body 1 are connected as a whole, so that the connection strength of the deformation part and the body 1 is better.

[0038] Specifically, the first component A has a first cavity a1, and the first cavity a1 has a first deformation opening a2. The second component B has a second deformation opening b. The first cavity a1 is connected to the second deformation opening b through the first deformation opening a2 to form a hollow and closed inner deformation cavity. The two first cavities a1 and the second deformation opening b form an integral inner deformation cavity, so that the deformation part has complete deformation space in the length direction.

[0039] Further, the first component A includes symmetrically arranged first connecting portions a4, so that the whole dummy rail is a symmetric structure. One end of the first connecting portion a4 is connected to the body 1, and the other end is connected to the second component B. The first connecting portion a4 is an arc-shaped connecting portion, and the angle of the first connecting portion a4 is preferably 90°-150°. The top of the first connecting portion a4 is connected to the body 1. The arc-shaped first connecting portion a4 has a simple structure and is easy to process, and can increase elasticity and improve deformation force. Meanwhile, the connecting portion increases the connecting position of the connecting portion and the body 1, so as to ensure that the deformation part has higher strength.

[0040] As shown in Figure 3 and Figure 4 , when the dummy rail is inserted into the slider, the dummy rail is pressed and deformed under the action of the force F1. Since the dummy rail is made of an elastic material, the dummy rail generates a reaction force F2. Under the actions of the forces F1 and F2, the rolling body is firmly held and cannot fall off.

[0041] As shown in Figure 5 , the direction of the force F1 is perpendicular to the rolling groove (i.e., 45° direction), and the force F1 is decomposed into a force F3 in the axial direction. The force F3 causes the dummy rail to deform in the axial direction, and the arc-shaped first connecting portion a4 inhibits the deformation and generates a reaction force F4. Since the second component B also inhibits the deformation, a reaction force F5 is generated. The reaction forces F4 and F5 jointly generate the reaction force F2 of the above-mentioned 1.

[0042] Embodiment 2, as shown in Figure 6 and Figure 7 , the first component A has a hollow and closed second cavity a3, and the component B is a solid structure. The inner deformation cavity includes a plurality of independent second cavities a3. The deformation part with this structure has basically the same action as the deformation part of embodiment 1, and has similar effects.

[0043] Embodiment 3, three first components A and two second components B can be arranged in the body, and the first components A are connected through the second components B to form an integral deformation part, and the rest is the same as embodiment 1.

[0044] Embodiment 4, three first components A and two second components B can be arranged in the body, and the first components A are connected through the components B to form an integral deformation part, and the rest is the same as embodiment 2.

[0045] Of course, the number of component A and component B can be selected according to actual needs, here no longer exhaust.

[0046] In summary, the present application ensures that the dummy rail and the rolling body are kept in a tight state, which can stably keep the rolling body and avoid the problem of rolling body falling off.

[0047] The above is based on the ideal embodiment of the present application, through the above description, the relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined by the scope of the claims.
