[0002] A refrigerator is a household appliance in people's lives. The refrigerator realizes the refrigeration and freezing storage operations of food. Usually, a pull-out storage box connected by a guide rail is arranged in the refrigerator freezer. The structure of the guide rail generally includes a slider, a chute, a spring, a fork, etc. When the pull-out storage box is pulled open, the slider starts to slide from the initial position until it moves to the end of the chute. At this time, the slider can be fixed at the end of the chute under the action of the pulling force of the spring. When the pull-out storage box is closed, the fork pushes the slider to slide in the direction of the head end of the chute until it returns to the initial position, thereby realizing the return of the guide rail. However, when the pull-out storage box is quickly pulled open, due to the too fast pulling speed, the slider will return to the initial position under the action of the spring pulling force, making it unable to be stable at the end of the chute, and thus the guide rail cannot return.

[0003] Therefore, it is necessary to research and develop a guide rail to solve the above problems. Summary of the Utility Model

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product, or equipment that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or equipment.

[0028] The following describes the embodiments with reference to the drawings. The drawings do not limit the disclosed content recorded in the claims in any way.

[0029] The following will introduce a guide rail provided by an embodiment of the present utility model in conjunction with the attached Figure 1 drawings. The guide rail includes a fixed rail 1 and a sliding rail 2 slidably connected to the fixed rail 1, and further includes a main bracket 3, a slider 4, a traction block 5 cooperating with the slider 4, and a tension mechanism fixedly connected to the slider 4;

[0030] One of the fixed rail 1 and the sliding rail 2 is provided with the slider 4, and the other is provided with the traction block 5;

[0031] The main bracket 3 is provided with a chute 31, and the chute 31 includes a first chute section 311 and a second chute section 312 that are connected. The length direction of the first chute section 311 is set along the sliding direction of the sliding rail 2, and the length direction of the second chute section 312 intersects with the sliding direction of the sliding rail 2;

[0032] The tension mechanism is arranged on the side of the main bracket 3 away from the chute 31 and is used to provide a return force to the slider 4. The direction of the return force points from the second chute section 312 to the first chute section 311 along the second chute section 312. When the sliding rail 2 slides relative to the fixed rail 1 in the direction towards the second chute section 312, the traction block 5 can drive the slider 4 to slide along the first chute section 311 to the second chute section 312. By adopting the above guide rail, when the pull-out storage box is quickly pulled open, the slider 4 can be stably at the end of the chute 31, and thus the guide rail can be quickly returned to its position.

[0033] In some embodiments, the shape of the chute 31 is L-shaped.

[0034] In some embodiments, the included angle between the first chute section 311 and the second chute section 312 is 85 - 90°. By limiting the above included angle, the slider 4 can enter the second chute section 312 more quickly, and thus the slider 4 can be stably in the second chute section 312 in time, and the guide rail can be quickly returned to its position.

[0035] Specifically, the included angle between the first chute section 311 and the second chute section 312 is 88 - 89°. By further limiting the above included angle, the stability of the slider 4 being stable in the second chute section 312 is increased.

[0036] In some embodiments, an arc section 313 is provided at the intersection of the first chute section 311 and the second chute section 312. By providing the arc section 313, the resistance for the slider to enter the second chute section 312 is reduced, and the phenomenon that the slider 4 is separated from the traction block 5 and the guide rail cannot be returned to its position is avoided.

[0037] In some embodiments, the radius of the arc section 313 does not exceed 1 mm. By further limiting the radius of the arc section 313, the time for the slider 4 to enter the second chute section 312 from the first chute section 311 is shortened, so that the slider 4 can enter the second chute section 312 in time.

[0038] Specifically, the radius of the arc segment 313 is less than 1 mm.

[0039] In some embodiments, a first guiding post 41 is provided on the slider 4. The first guiding post 41 is slidably connected to the sliding groove 31, and the first guiding post 41 has a clearance fit with the second sliding groove segment 312. Through the above arrangement, the resistance of the slider 4 entering the second sliding groove segment 312 is reduced.

[0040] In some embodiments, the clearance between the first guiding post 41 and the second sliding groove segment 312 is 0.6 - 1.2 mm. By further defining the range of the clearance, the resistance of the slider 4 and thus the second sliding groove segment 312 can be further reduced, enabling the slider 4 to enter the second sliding groove segment 312 in a timely manner.

[0041] In some embodiments, the slider 4 is further provided with a second guiding post 42 slidably connected to the sliding groove 31. The second guiding post 42 and the first guiding post 41 are spaced apart. When the first guiding post 41 slides to the second sliding groove segment 312, the second guiding post 42 is located in the first sliding groove segment 311. By providing the second guiding post 42, the slider 4 has better stability and smoother movement during operation.

[0042] Specifically, when the first guiding post 41 slides to the second sliding groove segment 312, the first guiding post 41 is located in the second sliding groove segment 312.

[0043] In some embodiments, the slider 4 is provided with a groove, and the towing block 5 is provided with a clamping portion that cooperates with the groove. By adopting the above arrangement, the assembly of the guide rail is made more convenient.

[0044] In some embodiments, when both the first guiding post 41 and the second guiding post 42 slide on the first sliding groove segment 311, both sides of the towing block are in contact with the inner wall of the groove. At this time, the towing block 5 can provide a thrust to the slider 4 to make the slider 4 slide in the direction of the second sliding groove segment 312.

[0045] In some embodiments, as shown in the attached Figure 3 figure, when the first guiding post 41 slides to the second sliding groove segment 312, one side of the towing block 5 is in contact with the inner wall of the groove. At this time, the towing block 5 can provide a thrust to the slider 4, thereby preventing the slider 4 from directly sliding from the second sliding groove segment 312 to the first sliding groove segment 311 under the action of the return force of the tension mechanism.

[0046] In some embodiments, the tension mechanism includes an elastic member and a damper. The slider 4 is provided with a first mounting position and a second mounting position. One end of the elastic member is fixedly connected to the first mounting position, and the other end is fixedly connected to the main bracket 3. One end of the damper is fixedly connected to the second mounting position, and the other end is fixedly connected to the main bracket 3. By adopting the above arrangement, the tension mechanism is detachably connected to the slider 4, making the installation of the guide rail convenient and faster, and at the same time improving the stability of the guide rail.

[0047] Specifically, the damper is provided with a telescopic rod, and one end of the telescopic rod is fixedly connected to the second mounting position of the slider 4.

[0048] In some embodiments, when the sliding rail 2 slides relative to the fixed rail 1 towards the second chute section 312, under the action of the return force of the tension mechanism, the slider 4 slides along the second chute section 312 to the first chute section 311.

[0049] In some embodiments, the main bracket 3 is provided with a first receiving groove and a second receiving groove. The first receiving groove is used to receive the elastic member, and the second receiving groove is used to receive the damper.

[0050] In some embodiments, the guide rail further includes an intermediate rail connected to the fixed rail. The intermediate rail is located between the fixed rail 1 and the sliding rail 2 and is slidably connected to the fixed rail 1 and the sliding rail 2 respectively.

[0051] This embodiment also provides a pull-out storage box, which includes the guide rail of any of the above embodiments. Using the guide rail on the pull-out storage box of the refrigerator enables the guide rail to return to its position in time, greatly improving the user experience.
