[0002] In daily life, people need to store different things at home. Various types of storage furniture are basically essential items for every household. For example, cabinets, wardrobes and other storage furniture will use pull-out baskets to help with storage and improve efficiency. The different spaces between different storage furniture result in different specifications of pull-out baskets. This requires the use of a fixing device for the pull-out basket slide to connect and fix it to various types of furniture, and then adjust the extension distance of the connecting piece to ensure that the fixing device is suitable for different pull-out baskets. However, people have discovered a problem in long-term use. The connecting piece has two connection points. When people need to adjust the connecting piece, they need to control both sides of the connecting piece to prevent uneven force on both sides from causing the connecting piece to tilt and slide, thereby getting stuck and deformed.

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] See also Figure 1-5 The utility model provides a fixing device for a pull-out basket slide rail, including a fixing seat 1 and a connecting piece 2. The fixing seat 1 includes a vertical surface 3 and a horizontal surface 4 connected to the vertical surface 3. A fixing hole 30 is provided at the top of the vertical surface 3. Sliding grooves 40 are provided at both sides of the bottom of the horizontal surface 4. A protrusion 100 is provided between the sliding grooves 40. Both sides of the connecting piece 2 are movably arranged on the sliding grooves 40. A recess 101 cooperating with the protrusion 100 is provided in the middle of the connecting piece 2.

[0024] In the above structure, the fixing seat is connected to the specified position through the fixing hole. When different models of pull-out baskets need to use the fixing seat, the extension distance of the connecting piece can be adjusted, and the connecting piece can be pushed to move forward and backward through the sliding groove. During the movement of the connecting piece, the recessed portion arranged thereon is close to the protrusion on the fixing seat, and the protrusion plays a guiding role to prevent the connecting piece from tilting and deforming due to uneven force on the connecting piece, thereby greatly increasing the service life of the fixing device.

[0025] Specifically, the fixing holes 30 are at least one pair and are symmetrically arranged. The symmetrical arrangement can not only improve the stability of the fixing seat and prevent the fixing seat from tilting to one side, but also increase the aesthetic feeling and achieve a non-obtrusive visual effect.

[0026] Specifically, the protrusion 100 is in the shape of an elongated strip and has a triangular top, and the recess 101 is adjacent to the protrusion 100. The elongated protrusion has a better guiding effect, and the triangle allows the protrusion and the recess to fit tightly, preventing gaps from causing the overall position to shift.

[0027] Specifically, threaded through holes 20 are provided at both ends of the connecting piece 2, and a screw passes through the threaded through hole 20 and is arranged on the sliding groove 40. The fixing seat 1 is connected to the connecting piece 2. The threaded through hole has the advantages of better fastening, convenient installation and removal of screws, and the ability to accurately control the position of the screw.

[0028] Specifically, a connecting rib 5 is provided between the vertical surface 3 and the horizontal surface 4, and the connecting rib can prevent the fixing seat from being deformed due to force.

[0029] Specifically, the left end of the protrusion 100 does not exceed the left end of the sliding groove 40, and the right end of the protrusion 100 exceeds the right end of the sliding groove 40. The length of the left end of the protrusion below the left end of the sliding groove is less than the length of the recess. This can ensure that the guiding effect of the protrusion on the connecting piece is not affected while reducing the material required for the protrusion to save costs. The right end of the protrusion exceeds the sliding groove to ensure that the connecting piece does not leave the protrusion after sliding to the rightmost recess, thereby preventing the connecting piece from being displaced and causing damage to the connecting piece.

[0030] Specifically, a protrusion 6 is provided on the horizontal surface 4, and the protrusion 6 is horizontally placed at the right end of the protrusion 100. The function of the protrusion is to ensure that when the connecting piece slides to the right end, the slight tilt of the connecting piece caused by uneven force on the left and right sides when the user pushes the connecting piece is corrected, thereby increasing the stability of the overall movement of the connecting piece and preventing the connecting piece from tilting.

[0031] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
