[0005] The utility model adopts the technical scheme as follows: a slide rail of pullable extension desktop, characterized by: including the table main body, the table main body lower side is connected with the expansion desktop plate and slides, the expansion desktop plate both sides are connected with the table main body through the slide rail mechanism, the slide rail mechanism includes the fixed frame setting in the table main body lower side and two sliding frames setting in the expansion desktop plate bottom and two sliding frames are located fixed frame both sides respectively, the fixed frame is fixedly connected with the table main body through two I-shaped frame, the sliding frame is fixedly connected with the sliding block in fixed frame one side close, the fixed frame both sides are equipped with the slide groove that the sliding block slides.

[0006] As a further improvement of the utility model, the table main body bottom is fixedly connected with four rectangularly distributed support columns.

[0007] As a further improvement of the utility model, the slide groove front end extends to U type and the fixed frame side wall is located at the slide groove edge and is designed as a round angle.

[0008] As further improvement of the utility model, the sliding block is clamped at the sliding groove of the fixed frame side wall and the middle part is designed as a round corner.

[0009] The utility model discloses the beneficial effect is: (1) the utility model discloses the sliding block is clamped at the sliding groove of the fixed frame side wall, and the fixed frame can effectively prevent the derailment of sliding block in the sliding process, avoids the table board to shake or slip when drawing, thereby improve the user's use experience. (2) the middle part of the utility model discloses the sliding block adopts the round corner design, and the round corner edge of the sliding groove is matched, reduces the friction when sliding, ensures the smooth sliding of sliding block in the sliding groove, not only improves the smoothness of sliding, but also prolongs the service life of the sliding rail, reduces the abrasion problem after long -term use.

[0018] The orientation terms mentioned or possibly mentioned in the present specification, such as up, down, left, right, front, back, front side, back side, top, bottom, etc., are defined relative to the configuration thereof, and are relative concepts. Therefore, it is possible to change accordingly according to different positions, different use states, and therefore these or other orientation terms should not be interpreted as restrictive terms.

[0019] The singular forms "a", "said", and "the" used in the present specification are intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means and includes any or all possible combinations of one or more associated listed items.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved in the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present application and do not limit the present application.

[0021] The utility model provides a kind of slide rail of pullable extension desktop as shown in the drawings Figures 1-7 As shown in the drawings, the utility model discloses a kind of slide rail of pullable extension desktop, including table main body 1, four rectangular distribution support columns 8 are fixedly connected in the bottom of table main body 1, expansion desk plate 2 is slidably connected in the lower of table main body 1, expansion desk plate 2 both sides are connected with table main body 1 by slide rail mechanism, the slide rail mechanism includes the fixed frame 3 being arranged in the lower of table main body 1 and the two sliding frames 4 being arranged in the bottom of expansion desk plate 2 and two sliding frames 4 are located at the two sides of fixed frame 3 respectively, the fixed frame 3 is fixedly connected with table main body 1 by two I-shaped frame 5, the sliding block 6 is fixedly connected on the side of fixed frame 3 close to the sliding block 6, the fixed frame 3 both sides are equipped with the sliding groove 7 for the sliding of sliding block 6.

[0022] As shown in the drawings, Figures 4-7 The front end of the sliding groove 7 in the utility model extends to U type and the side wall of fixed frame 3 is designed as round angle at the edge of sliding groove 7, one end of sliding block 6 is clamped in the sliding groove 7 of the side wall of fixed frame 3 and the middle is designed as round angle, which can avoid sliding block 6 from sliding out of sliding groove 7, avoid expansion desk plate 2 from shaking or slipping when pulling, improve stability, the round angle design of sliding block 6 and sliding groove 7 is matched, not only improve the fluency of sliding, but also effectively reduce the noise in the sliding process, provide more comfortable use environment for user
