Description

Technical Field

[0001] The invention relates to the technical field of refrigerator guide rails, and in particular to a refrigerator with a sheet metal guide rail structure. Background Art

[0002] Most of the existing sheet metal rail French refrigerators in the industry are drawer-type door assemblies. In order to improve the competitiveness of the products in the market, the slide rails of the drawer-type door assemblies all use simple slide rails, and the drawers are opened and closed by sliding the main slide rail assembly fixed on the door body; Figure 1 As shown, the main slide rail assembly includes two guide rails, and a U-shaped connecting rod is arranged between the two guide rails. The U-shaped connecting rod and the guide rails are installed by riveting, and the main slide rail assembly is generally transported after being installed by the parts manufacturer. The U-shaped connecting rod is easily bent by force during transportation, which causes deviation in the parallelism of the two guide rails and affects the pushing and pulling of the drawer. At the same time, the U-shaped connecting rod and the guide rail are not convenient to transport after installation.

[0003] In view of this, the existing technology still needs to be improved and developed. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a refrigerator with a sheet metal guide rail structure, aiming to solve the problem in the prior art that the U-shaped connecting rod of the main slide rail assembly is easily bent under force, resulting in deviation in the parallelism of the slide rail and inconvenient transportation.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0006] A refrigerator with a sheet metal guide rail structure, comprising:

[0007] a housing having an opening;

[0008] Two slot plates are provided on the inner wall of the shell and are symmetrically arranged along the opening;

[0009] Two slide rails are respectively slidably arranged on the opposite sides of the two slot plates; the opposite sides of the two slide rails are respectively provided with open slots, and the open slots are provided with bent fixing plates;

[0010] A connecting straight rod is detachably arranged between the two bending fixing plates;

[0011] The drawer door is arranged on one side of the two slide rails.

[0012] According to the above technical solution, by arranging a bending fixing plate on the two slide rails and arranging a detachable connecting straight rod between the two bending fixing plates, it is not only convenient to disassemble and transport, but also the strength of the slide rails can be improved through the structure of the bending fixing plate to avoid parallelism deviation caused by external force.

[0013] Furthermore, the bent fixing plate is in a U shape, and the bent fixing plate protrudes from one side of the slide rail so that the bent fixing plate is spaced apart from a side wall of the slide rail.

[0014] According to the above technical solution, the bent fixing plate protrudes from one side of the slide rail, and the two side edges of the bent fixing plate form a certain angle with the middle side edge, which can not only increase the strength of the slide rail, but also facilitate fixed connection to the straight rod.

[0015] Furthermore, a slide groove is provided on the side facing each other of the two groove plates, a guide groove is provided on the side opposite to each other of the two slide rails, a first roller is rotatably provided on the side facing each other of the two groove plates, the first roller cooperates with the guide groove, and a second roller is provided on the side opposite to each other of the two slide rails, the second roller cooperates with the slide groove.

[0016] According to the above technical solution, by cooperating between the slide groove and the second roller, and the guide groove and the first roller, the friction between the slide rail and the groove plate can be effectively reduced, thereby improving the push-pull efficiency.

[0017] Furthermore, a convex plane is provided on the opposite sides of the two slide rails, and the second roller is arranged on the convex plane.

[0018] According to the above technical solution, by providing the convex plane, it can be ensured that the second roller and the convex plane are in a parallel state, thereby ensuring the parallelism of the slide rail and the groove plate when sliding.

[0019] Furthermore, chamfers are provided on both sides of the slide groove, a rounded corner is provided on the top of one end of the guide groove close to the opening of the shell, and two limit platforms are provided on the top of one end of the guide groove away from the opening of the shell, and the two limit platforms are arranged at intervals.

[0020] According to the above technical solution, the inclination direction of the drawer can be changed by setting the chamfer, and the drawer provides a force to slide inward as the chamfer tilts, thereby improving the sealing and stability of the drawer door; at the same time, a rounded corner is provided at the top of the end of the guide groove close to the opening of the shell, and the rounded corner of the guide groove is bent upward, which can not only effectively avoid interference between the first roller and the guide groove, affecting the pulling of the drawer door, but also when the drawer door is closed, the rounded corner acts on the first roller, so that the drawer provides a force to slide inwardly of the shell, and at the same time, the drawer can be slightly tilted inwardly of the shell, further improving the stability of the drawer.

[0021] Furthermore, the outer side wall of the slide groove and the outer side wall of the guide groove are both provided with a rib.

[0022] According to the above technical solution, the provision of the retaining edge can effectively prevent the first roller from being separated from the guide groove and the second roller from being separated from the slide groove.

[0023] Furthermore, the first roller rolls along the center line of the guide groove, and the second roller rolls along the center line of the slide groove.

[0024] According to the above technical solution, the first roller rolls along the center line of the guide groove and the second roller rolls along the center line of the slide groove, thereby ensuring parallel sliding between the slide rail and the groove plate to avoid interference between the two and affecting the drawing out of the drawer.

[0025] Furthermore, a plurality of buckles are provided on the opposite sides of the two slot plates, and a plurality of slots are provided on the inner wall of the shell. The buckles correspond to the slots one by one and cooperate with each other.

[0026] According to the above technical solution, by setting the buckle and the slot, not only can the slot plate be fixed conveniently, but the slot plate can also be positioned, thereby avoiding deviation between the two slot plates, resulting in parallelism deviation and affecting the push-pull effect of the drawer.

[0027] Furthermore, the slot plate is connected to the shell by screws.

[0028] According to the above technical solution, the slot plate can be easily disassembled and replaced by installing screws.

[0029] Furthermore, the corner diameter of the guide groove is smaller than the rounded corner diameter of the first roller.

[0030] According to the above technical solution, the angle diameter of the guide groove is smaller than the rounded corner diameter of the first roller, which can effectively avoid interference between the first roller and the angle of the guide groove, thereby ensuring the rolling smoothness of the first roller.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, an opening is provided on one side of the shell, and groove plates are respectively provided on two inner walls adjacent to the opening inside the shell, the two groove plates are symmetrically arranged, and a slide rail is slidably provided on the opposite sides of the two groove plates, and an opening groove is provided on the opposite sides of the two slide rails, and a bending fixing plate is provided in the opening groove, and a connecting hole is provided on the bending fixing plate, and a connecting straight rod is provided between the two bending fixing plates, and the two ends of the connecting straight rod are respectively connected to the two bending fixing plates by bolts, and a drawer door is provided on one side of the two slide rails; by arranging the bending fixing plates on the two slide rails and arranging a detachable connecting straight rod between the two bending fixing plates, it is not only convenient to disassemble and transport, but also the strength of the slide rail can be improved through the structure of the bending fixing plates to avoid deviation in parallelism caused by external force.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figure 1 As shown, the main slide rail assembly in the prior art includes two guide rails and a U-shaped connecting rod, and the U-shaped connecting rod is fixed to the two guide rails by riveting at the manufacturer, and then transported after installation. This is not only inconvenient for transportation, but also easily affected by external forces, causing the U-shaped connecting rod to bend or be damaged, thereby causing deviations in the parallelism of the two guide rails; the U-shaped connecting rod is fixed to the two guide rails by riveting, which is not convenient for subsequent disassembly and replacement after fixation, and it is also inconvenient to adjust the installation position of the U-shaped connecting rod, so as to achieve the problem of adjusting the parallelism of the two guide rails.

[0045] In view of the shortcomings of the prior art, this embodiment provides a refrigerator with a sheet metal guide rail structure, which can be specifically referred to as follows:

[0046] As attached Figure 2 , Attachment Figure 3 and attached Figure 4As shown, a refrigerator with a sheet metal guide rail structure includes a shell 1, two groove plates 2, two slide rails 3, a connecting straight rod 4 and a drawer door; the shell 1 is the inner shell of the refrigerator (the outer shell of the refrigerator is not shown), and an opening 11 is provided on one side of the shell 1, and the opening 11 is used to install the refrigerator door and facilitate the drawer door to slide and open. A groove plate 2 is provided on the inner walls of the shell 1 on both sides adjacent to the opening 11, and the two groove plates 2 are symmetrically arranged on the two inner walls of the shell 1, that is, the two groove plates 2 are symmetrically arranged along the opening 11 to facilitate the support of the drawer door to slide; a slide rail 3 is slidably provided on the opposite side of the two groove plates 2, that is, the slide rail 3 can slide on the surface of the groove plate 2, and an opening groove 31 is provided on the opposite side of the two slide rails 3, and the opening groove 31 is located at the end of the slide rail 3 away from the opening 11 of the shell 1. A bending fixing plate 32 is provided on the inner wall of 31, and the bending fixing plate 32 is U-shaped, and the two sides of the bending fixing plate 32 are arranged at a certain angle to the middle, and a connecting hole is provided on the bending fixing plate 32, and a detachable connecting straight rod 4 is provided between the two bending fixing plates 32; a drawer door is provided on the side of the two slide rails 3 close to the opening 11 of the shell 1; by providing a bending fixing plate 32 on the two slide rails 3 and providing a detachable connecting straight rod 4 between the two bending fixing plates 32, the two slide rails 3 and the connecting straight rod 4 can be disassembled during transportation, thereby facilitating transportation, and the slide rail 3 and the connecting straight rod 4 can be detachably arranged, which is also convenient for replacement after the slide rail 3 or the connecting straight rod 4 is damaged, and the structure of the bending fixing plate 32 can also improve the strength of the slide rail 3 to avoid deviation in parallelism caused by external force.

[0047] Specifically, the slide rail 3 is a sheet metal part, and the slide rail 3 and the connecting straight rod 4 are produced by the same manufacturer and transported to the refrigerator manufacturer in a disassembled state; when assembly is required, the two slot plates 2 can be first installed on the inner wall of the shell 1, and then the two slide rails 3, the connecting straight rod 4 and the drawer door can be assembled to form a quadrilateral structure, and then the two slide rails 3 can be slidably matched with the corresponding slot plates 2 respectively to complete the installation of the guide rail assembly; the present application can facilitate transportation by setting the slide rail 3 and the connecting straight rod 4 to be detachable, and at the same time, a bent fixing plate 32 is set at the position of the connecting straight rod 4, which can not only increase the stability of the slide rail 3 and avoid the problem of parallelism deviation caused by external force hitting the connecting straight rod 4 or the slide rail 3, but also facilitate the installation of the connecting straight rod 4 to avoid the protrusion of the installation position to affect the overall sliding of the slide rail 3.

[0048] In this embodiment, as shown in the attached Figure 4As shown, the bent fixing plate 32 is U-shaped, and the bent fixing plate 32 protrudes from one side of the slide rail 3 so that the bent fixing plate 32 and the side wall gap of the slide rail 3 are arranged, and the two side edges of the bent fixing plate 32 are arranged in the open groove 31, and the two side edges of the bent fixing plate 32 form a certain angle with the middle side edge, thereby increasing the stability of the bent fixing plate 32 and preventing it from deforming; at the same time, a connecting hole is opened in the middle position of the bent fixing plate 32, and threaded holes are respectively provided at both ends of the connecting straight rod 4, and the two threaded holes correspond to the two connecting holes one by one, and the connecting straight rod 4 can be fixed to the two bent fixing plates 32 by bolts The diameter of the threaded end of the bolt is smaller than the diameter of the connecting hole, while the diameter of the big head end of the bolt is larger than the diameter of the connecting hole. At the same time, a gasket and a spring sheet can be arranged between the big head end of the bolt and the bent fixing plate 32 to increase the stability after the bolt is fixed; while fixing, the installation condition can be observed through the gap between the side of the bent fixing plate 32 and the side of the slide rail 3 to increase the installation speed, and it is also convenient to fine-tune the connecting straight rod 4; the two bent fixing plates 32 protrude from the surface of the slide rail 3 on the opposite side, which can effectively prevent the connecting straight rod 4 from being deformed when being hit by external force, thereby avoiding deformation of the bent fixing plate 32 and the connecting straight rod 4.

[0049] When the two bent fixing plates 32 protrude from the surface of the slide rail 3 toward each other, a recessed groove will be formed on the other side of the slide rail 3, and the connecting straight rod 4 is fixed to the two bent fixing plates 32 by bolts, and the bolts are located in the recessed groove and do not protrude from the surface of the slide rail 3, which can effectively prevent the end of the bolt from affecting the sliding of the slide rail 3.

[0050] In this embodiment, as shown in the attached Figure 3 and attached Figure 5 As shown, a slide groove 21 is provided on the opposite side of the two slot plates 2, and the slide groove 21 is arranged along the length direction of the slot plate 2; a guide groove 33 is provided on the opposite side of the two slide rails 3, and the two guide grooves 33 are arranged along the length direction of the slide rail 3; a first roller 22 is rotatably provided on the opposite side of the two slot plates 2, and the first roller 22 is located at the top of one end of the slot plate 2 close to the opening 11 of the shell 1, so as to facilitate the first roller 22 to abut against the top wall of the guide groove 33 to provide a sliding effect; a second roller 34 is provided on the opposite side of the two slide rails 3, and the second roller 34 is located at the bottom of the end of the slide rail 3 away from the opening 11 of the shell 1, so as to facilitate the second roller 34 to abut against the bottom wall of the slide groove 21; through the cooperation between the slide groove 21 and the second roller 34, and the cooperation between the guide groove 33 and the first roller 22, the friction between the slide rail 3 and the slot plate 2 can be effectively reduced, and the push-pull efficiency can be improved.

[0051] Furthermore, the first roller 22 and the second roller 34 may be rubber wheels, which can effectively reduce the noise when the slide rail 3 and the groove plate 2 slide.

[0052] In this embodiment, as shown in the attached Figure 3As shown, a convex plane 35 is provided on the opposite side of the two slide rails 3, and the second roller 34 is arranged on the convex plane 35; specifically, a connecting rod is provided on one side of the second roller 34, and the connecting rod is arranged on the convex plane 35, so as to ensure that the second roller 34 and the convex plane 35 are in a parallel state, thereby ensuring the parallelism of the slide rail 3 and the groove plate 2 when sliding.

[0053] Furthermore, the convex plane 35 is 0.1 mm higher than the surface of the slide rail 3 , and the convex plane 35 is in a flat state.

[0054] Furthermore, a through hole is provided on the convex plane 35, and the through hole passes through the slide rail 3. A concave plane is provided on the side of the slide rail 3 away from the convex plane 35. A thread is provided at one end of the connecting rod and passes through the through hole. A nut is provided on the concave plane, and the nut cooperates with the connecting rod thread to further strengthen the stability of the second roller 34. At the same time, the parallelism of the second roller 34 can also be improved through the concave plane; the connecting rod is provided with a circular rib on one side of the convex plane 35, and the circular rib abuts against the convex plane 35, which can be used for limiting and confirming the position of the second roller 34, and also facilitates the fixation between the nut and the connecting rod.

[0055] Furthermore, the nut and the concave plane are fixed by welding, thereby preventing the nut from loosening.

[0056] In this embodiment, as shown in the attached Figure 5 As shown, both sides of the slide groove 21 are provided with chamfers 23, and the chamfers 23 are inclined from the middle of the slide groove 21 to the bottom of both sides, and the second rollers 34 cooperate with the slide groove 21 and the chamfers 23; when the drawer door is closed, the second rollers 34 are located inside the shell 1, and the second rollers 34 cooperate with the chamfers 23 at one end of the slide groove 21 away from the opening 11 of the shell 1. Under the gravity of the slide rail 3 and the drawer, the second rollers 34 abut against the chamfers 23, and provide a force to slide inward as the chamfers 23 tilt, thereby improving the sealing and stability of the drawer door; when the refrigerator shakes, the drawer door can also effectively avoid falling off the refrigerator; and the slide groove 21 close to the opening 11 of the shell 1 The chamfer 23 at the end can facilitate the insertion of the second roller 34 of the slide rail 3 into the slide groove 21 and play a guiding role; the top of the end of the guide groove 33 close to the opening 11 of the shell 1 is provided with a rounded corner, and the rounded corner of the guide groove 33 is bent upward, which can not only effectively avoid interference between the first roller 22 and the guide groove 33 and affect the pulling of the drawer door, but also when the drawer door is closed, the rounded corner of the guide groove 33 can abut on the first roller 22. Since the first roller 22 is fixed to the groove plate 2, the groove plate 2 is in a fixed state, with the effect of the rounded corner, the drawer can provide a force to slide toward the inside of the shell 1, and at the same time, the drawer can be slightly tilted toward the inside of the shell 1, thereby further improving the stability of the drawer.

[0057] Further, as attached Figure 4As shown, two limit platforms 36 are arranged at intervals on the top of one end of the guide groove 33 away from the opening 11 of the shell 1; specifically, the guide groove 33 is formed by bending sheet metal, and two grooves are arranged on the top of one end of the guide groove 33 away from the opening 11 of the shell 1, and the grooves protrude into the guide groove 33, thereby forming two limit platforms 36 in the guide groove 33, and the two limit platforms 36 are arranged at intervals; when the drawer door is opened to a certain limit, the first roller 22 will roll along the guide groove 33 and hold on the first limit platform 36, that is, the drawer is informed of the pulling state, and the drawer can be further pulled at this time, so that the first limit platform 36 is at the first limit platform 36. The drawer slides on a roller 22, and the guide groove 33 between the two limit platforms 36 cooperates with the first roller 22. The two limit platforms 36 can effectively limit the drawer, which can facilitate manual loading and unloading of goods in the drawer; and the second limit platform 36 located inside the guide groove 33 is horizontally arranged. When the drawer is pulled to the second limit platform 36 and contacts the first roller 22, the inside of the drawer will be raised under the action of the first roller 22, thereby notifying that the drawer is about to be pulled out of the refrigerator; at the same time, the second limit platform 36 is horizontally arranged, and the guide groove 33 is provided with a disassembly port at the second limit platform 36 to facilitate the drawer to be separated from the refrigerator for cleaning and replacement.

[0058] In this embodiment, the guide groove 33 is formed by bending the side wall of the slide rail 3, and the guide groove 33 is U-shaped. The first roller 22 is located in the guide groove 33, and both sides of the guide groove 33 can be used to limit the first roller 22 to prevent the first roller 22 from escaping from the guide groove 33 during operation; and the angle of the guide groove 33 is smaller than the rounded corner of the first roller 22, thereby avoiding the influence of the angle of the guide groove 33 on the rolling of the first roller 22.

[0059] Further, as attached Figure 4 and attached Figure 5 As shown, the outer wall of the slide groove 21 and the outer wall of the guide groove 33 are both provided with a retaining edge 5 for covering the one side notch of the slide groove 21 and the guide groove 33. The outer wall retaining edge 5 of the slide groove 21 is used to limit the lateral movement direction of the second roller 34. The outer wall retaining edge 5 of the guide groove 33 is a folded edge, which is also used to limit the lateral movement direction of the first roller 22, so that the first roller 22 and the second roller 34 can roll normally.

[0060] In this embodiment, the first roller 22 rolls along the center line of the guide groove 33, and the second roller 34 rolls along the center of the slide groove 21. The first roller 22 and the second roller 34 are not on the same line, but the guide groove 33 and the slide groove 21 are parallel to each other. The first roller 22 and the second roller 34 are parallel to the side wall of the groove plate 2, thereby ensuring parallel sliding between the slide rail 3 and the groove plate 2 to avoid interference between the two and affecting the withdrawal of the drawer.

[0061] Furthermore, the distance between the first roller 22 and the guide groove 33 away from the side wall of the groove plate 2 is 1.5 mm, and the distance between the second roller 34 and the slide groove 21 away from the side wall of the slide rail 3 is also 1.5 mm. The gaps before and after the slide rail 3 are uniform, which can ensure the stability of the slide rail 3 when pushing and pulling, and at the same time, the slide rail 3 will not cause too much shaking when sliding.

[0062] Furthermore, foam is filled between the outer side of the shell 1 and the outer shell of the refrigerator. As the foam expands and contracts, the distance between the inner walls of the two groove plates 2 set in the shell 1 will also change. When it changes, since the first roller 22 and the second roller 34 are in a parallel state in the initial state, when the inner wall of the shell 1 expands or contracts, there is a gap between the first roller 22 and the two side walls of the guide groove 33, and there is also a gap between the second roller 34 and the retaining edge 5 and the inner wall of the slide groove 21, so that it will not affect the sliding between the slide rail 3 and the groove plate 2.

[0063] In this embodiment, as shown in the attached Figure 6 and attached Figure 7 As shown, a plurality of buckles 6 are provided on the opposite sides of the two slot plates 2, and the plurality of buckles 6 are arranged at intervals. A plurality of slots are provided on the inner wall of the shell 1, and the buckles 6 correspond to the slots one by one and cooperate with each other. After the buckles 6 are fixed with the slots, the slot plates 2 can be further fixed by screws; when installing the slot plates 2, the buckles 6 can be first matched with the slots to preliminarily fix the slot plates 2, and then the slot plates 2 can be further fixed by screws; through the arrangement of the buckles 6 and the slots, not only can the slot plates 2 be fixed conveniently, but also the slot plates 2 can be positioned, thereby avoiding deviations between the two slot plates 2, resulting in deviations in their parallelism, and affecting the push-pull effect of the drawer.

[0064] Furthermore, a plurality of opening grooves 31 are provided on one side of the slide rail 3, each of the opening grooves 31 is provided with a bending fixing plate 32, and a plurality of reinforcing grooves are also provided on the slide rail 3. The overall stability of the slide rail 3 can be further improved by the plurality of bending fixing plates 32 and the plurality of reinforcing grooves.

[0065] Furthermore, a mounting plate is provided on one side of the slide rail 3 close to the opening 11 of the shell 1, and the mounting plate is connected to the drawer door by screws; the mounting plate is formed by bending one end of the slide rail 3, thereby improving the connectivity and stability between the mounting plate and the slide rail 3.
