[0023] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0024] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0026] The embodiment of the utility model provides a dovetail slide rail structure which is convenient for controlling oil supply. Figure 1-3 As shown, it includes a static slide rail 100 and a movable slide rail 200. The static slide rail 100 includes a dovetail-shaped insert block 110 located at the top thereof, and the bottom surface of the movable slide rail 200 is provided with a dovetail groove adapted to the insert block 110. Specifically, the shape and size of the dovetail groove are respectively adapted to the shape and size of the insert block 110. The insert block 110 is embedded in the dovetail groove and slidably cooperates with the dovetail groove. The movable slide rail 200 can slide relative to the static slide rail 100, and the insert block 110 slides relatively in the dovetail groove.

[0027] The insert 110 is provided with an oil collecting tank 111 for loading oil, and the oil collecting tank 111 plays a role of temporarily storing oil. Both sides of the insert 110 are provided with oil drop grooves 112 connected to the oil collecting tank 111, and the height of the bottom wall of the oil drop groove 112 gradually decreases in the direction extending to the outside of the insert 110. The connection position between the bottom wall of the oil drop groove 112 and the oil collecting tank 111 is located at the preset overflow position of the oil collecting tank 111. The preset overflow position is a position of the oil collecting tank 111 in its height direction, which can be set in advance by those skilled in the art. When the oil in the oil collecting groove 111 exceeds the preset overflow position, the oil will naturally overflow from the connection position between the bottom wall of the oil dropping groove 112 and the oil collecting groove 111, and the overflowed oil will flow to the bottom wall of the oil dropping groove 112. Since the height of the bottom wall of the oil dropping groove 112 gradually decreases in the direction extending toward the outside of the insert 110, the oil in the oil dropping groove 112 will flow out from the side of the insert 110 along the bottom wall of the oil dropping groove 112, and finally flow to between the insert 110 and the inner wall of the dovetail groove.

[0028] When controlling the oil supply, it is only necessary to supply oil to the oil collecting tank 111 at a uniform speed, and the oil can be uniformly removed from the oil collecting tank 111, and then flow evenly between the insert block 110 and the inner wall of the dovetail groove, which reduces the difficulty of oil supply and facilitates the control of oil supply. There is continuous oil input between the insert block 110 and the movable slide rail 200, which ensures the lubricity between the movable slide rail 200 and the static slide rail 100.

[0029] In some embodiments, a liquid storage material that can absorb and store oil is provided in the oil collecting tank 111. When the movable slide rail 200 slides relative to the static slide rail 100 and the static slide rail 100 is affected by external vibration, the oil in the oil collecting tank 111 will also vibrate slightly, and this vibration will cause a small amount of excessive oil to overflow, thereby causing the oil to flow unevenly between the insert 110 and the inner wall of the dovetail groove. In this embodiment, the liquid storage material can make the oil in the oil collecting tank 111 less susceptible to vibration, and the oil can remain relatively stable to improve the uniformity of the oil flow.

[0030] Further, the liquid storage material is a sponge, which can absorb oil and has a good storage effect on the oil. Of course, the liquid storage material can also be made of cotton, cloth or other materials.

[0031] In some embodiments, the oil collecting groove 111 and the oil dropping groove 112 are both located at the top of the insert 110. The oil can flow down from the top of the side of the insert 110 and then adhere to the side of the insert 110. This utilizes the natural flow of liquid under the action of gravity, so that the oil can adhere to the side of the entire insert 110 to ensure the lubrication effect.

[0032] Furthermore, the oil collecting groove 111 is opened on the top surface of the insert 110, and the oil dropping groove 112 runs through the top surface of the insert 110. This allows the oil collecting groove 111 and the oil dropping groove 112 to be directly processed on the top surface of the insert 110, which facilitates the overall manufacturing and simplifies the processing difficulty.

[0033] In some embodiments, the surface of the static slide rail 100 is further provided with an oil inlet hole 113 connected to the oil collecting tank 111 , and an external supply device can supply oil to the oil collecting tank 111 through the oil inlet hole 113 to ensure that the oil collecting tank 111 is continuously loaded with oil.

[0034] In some embodiments, two oil collecting tanks 111 are provided, and the two oil drop tanks 112 are respectively connected to the two oil collecting tanks 111, and the oil in the two oil collecting tanks 111 falls from the two oil drop tanks 112 respectively. The size of a single oil collecting tank 111 can be smaller, and the connection path between the oil drop tank 112 and the oil collecting tank 111 is smaller, which facilitates the rapid outflow of the oil.

[0035] In some embodiments, a preset gap 120 is formed between the top surface of the insert 110 and the movable slide rail 200 , that is, the top surface of the insert 110 does not contact the movable slide rail 200 , so the top surface of the insert 110 and the movable slide rail 200 do not need to use oil.

[0036] In some embodiments, a groove 114 is disposed on the top surface of the insert 110 . The existence of the groove 114 can reduce the material used for the insert 110 , thereby reducing the manufacturing cost of the entire product.

[0037] In some embodiments, both the oil drop groove 112 and the oil collection groove 111 may extend along the sliding direction of the movable slide rail 200 relative to the static slide rail 100, so as to apply the oil as evenly as possible between the insert block 110 and the inner wall of the dovetail groove. The direction in which the oil drop groove 112 extends toward the outside of the insert block 110 is perpendicular to the sliding direction of the movable slide rail 200 relative to the static slide rail 100, so as to shorten the path of the oil drop groove 112 extending toward the outside of the insert block 110, so as to facilitate the oil to flow out of the oil drop groove 112 quickly.

[0038] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
