[0036] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0037] The utility model discloses the slide rail 4 mounting structure, apply to the slide on, the slide includes slide 1 and base 2, the base 2 is groovy, the slide 1 is placed in the groove, and the two inner side walls of base 2 and the two side walls of slide 1 are opened respectively corresponding mounting groove 3, and the slide rail 4 body is set in mounting groove 3, the groove bottom of mounting groove 3 includes a plurality of first datum surface 31 and a plurality of first reinforcing portion 32, and first datum surface 31 and first reinforcing portion 32 interval arrangement, first reinforcing portion 32 includes at least two first reinforcing surface 321, and the interval of two adjacent first datum surface 31 is less than the width of first reinforcing surface 321 in first reinforcing portion 32 sum, and the two side groove walls of mounting groove 3 form the horn mouth shape, and the opening of horn mouth is towards the groove bottom of mounting groove 3, so that mounting groove 3 whole is dovetail groove shape, the section of slide rail 4 body is similar with the section of mounting groove 3, and it includes interval arrangement a plurality of second datum surface 41 and a plurality of second reinforcing portion 42, second reinforcing portion 42 includes a plurality of with first reinforcing surface 321 in first reinforcing portion 32 corresponding second reinforcing surface 421, and the slide rail 4 body can be inserted in mounting groove 3, and when the slide rail 4 body inserts mounting groove 3, first reinforcing surface 321 and second reinforcing surface 421 are attached, first datum surface 31 and second datum surface 41 are attached, because the interval of two adjacent first datum surface 31 is less than the width of first reinforcing surface 321 in first reinforcing portion 32 sum and the interval of adjacent second datum surface 41 is less than the width of second reinforcing surface 421 in second reinforcing portion 42 sum, therefore the contact area between slide rail 4 body and mounting groove 3 increases, when the slide rail 4 body is installed in mounting groove 3, the contact surface of gluing between slide rail 4 and mounting groove 3 also increases, and because the bending effect of each face of first reinforcing portion 32 and second reinforcing portion 42, the glue is more easily attached on the part, prevents the degumming, and therefore improves the reliability of the connection between slide rail 4 body and mounting groove 3.

[0038] More specifically, in the embodiment, the first reinforcing part 32 has three first reinforcing surfaces 321, i.e. a first supporting surface 321a, a first limiting surface 321b and a first connecting surface 321c, and the second reinforcing part 42 has second supporting surfaces 421a, second limiting surfaces 421b and second connecting surfaces 421c corresponding to the first reinforcing surfaces 321 respectively. The first supporting surface 321a is arranged obliquely to form an angle with the horizontal plane, and faces outward above the mounting groove 3. The second supporting surface 421a is arranged obliquely downward. When the slide rail 4 is placed in the mounting groove 3, the first supporting surface 321a and the second supporting surface 421a are in close contact. Since the two surfaces are arranged obliquely, the mounting groove 3 of the base 2 can more easily bear the pressure received by the slide 1. The first limiting surface 321b and the second limiting surface 421b are arranged vertically to limit the slide rail 4 in the horizontal direction together with the first reference surface 31 and the second reference surface 41. The first connecting surface 321c is arranged between the first limiting surface 321b and the first reference surface 31, and the second connecting surface 421c is arranged opposite to the first connecting surface 321c. Optionally, in other embodiments, the skilled in the art can arrange two, four or five reinforcing surfaces in the first reinforcing part 32 and the second reinforcing part 42 according to the needs, such as the three first reinforcing surfaces 321 arranged in a trapezoidal shape in the embodiment, two reinforcing surfaces arranged in a V shape, and four reinforcing surfaces arranged in a rectangular shape.

[0039] The base 2 and the slide 1 are also provided with a riveting groove 5 arranged on one side of the mounting groove 3. In the embodiment, in order to facilitate the application of external force during processing, the riveting groove 5 is arranged on the side of the mounting groove 3 away from the groove bottom of the base 2. A pressing block 6 is arranged between the riveting groove 5 and the mounting groove 3. When the groove wall on the side of the riveting groove 5 close to the mounting groove 3 is subjected to an external force, the pressing block 6 can deform in the direction of the mounting groove 3, so that the groove wall on the side of the mounting groove 3 close to the riveting groove 5 moves inward, thereby clamping the slide rail 4 in the mounting groove 3.

[0040] The two groove walls of the riveting groove 5 are arranged with an acute angle, and the sharp corner of the acute angle faces the direction of the mounting groove 3, thereby reducing the strength of the root of the pressing block 6, facilitating the deformation of the pressing block 6, and making the upper edge of the pressing block 6 protrude upward, which is easier to apply force to the upper edge of the pressing block 6 during processing.

[0041] The two sides of the slide rail 4 body are respectively provided with limiting portions 43, and at least two ball grooves 45 are left between the two limiting portions 43, and a supporting portion 44 is arranged between every two adjacent ball grooves 45. In the embodiment, the slide base 1 is arranged opposite to the slide rail 4 on the base 2, and the cross sections of the two slide rails 4 are the same, and the two ball grooves 45 arranged opposite to each other enclose a slide for the ball 7 to roll on. More specifically, in the embodiment, two slide grooves are formed by the two sets of ball grooves 45 arranged opposite to each other on each slide rail 4, and the two sets of balls 7 are arranged in the two slide grooves respectively. A backflow channel 14 is opened on each side of the slide base 1 along the movement direction, the backflow channel 14 corresponds to the slide groove one by one, and the end cover 8 is connected between the end of the backflow channel 14 and the slide groove. Specifically, the end cover 8 is provided with a U-shaped ball 7 rotation channel 81, one end of the ball 7 rotation channel 81 is communicated with the slide rail 4 on the slide base 1, and the other end is communicated with the backflow channel 14. In the working process, each set of balls 7 is arranged in the slide groove, the rotation channel 81 and the backflow channel 14 in turn, forming a ring. When the slide base 1 moves, the ball 7 can enter the backflow channel 14 through the rotation channel 81 after moving to the limit position of the slide groove, so that the ball 7 rolls with the movement of the slide base 1, preventing the ball 7 from being stuck after moving to the limit position of the slide groove. In the embodiment, in order to prevent the ball 7 from being pulled out of the slide groove in the vertical direction due to external force in the movement process, a maintaining gap 46 is left between the two sets of balls 7. After the two slide rails 4 on the slide base 1 and the base 2 are installed, the supporting portions 44 of the two slide rails 4 respectively extend into the maintaining gap 46, separating the two sets of balls 7 in the slide groove, preventing the ball 7 from being pulled out of the slide groove range due to external force, causing the structure to move unsmoothly.

[0042] The slide table is provided with a threaded sleeve 11 fixed in the slide base 1, the threaded sleeve 11 is provided with a threaded blind hole at the top, the slide table is provided with a through hole, the threaded sleeve 11 and the slide base 1 are fixedly connected through bolts, one end of the base 2 is provided with a motor 12, the output shaft of the motor 12 is connected with a lead screw 13, the threaded sleeve 11 is screwed with the lead screw 13, and the movement of the slide table is controlled through the motor 12.

[0043] The above only describes the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
