Technical Field

[0001] The present application relates to the field of refrigerator equipment manufacturing, and in particular to a refrigerator guide rail installation device. Background Art

[0002] In the manufacturing process of refrigerators, the refrigerator liner needs to be installed to facilitate the installation of storage boxes for refrigeration and freezing of items. The main function of the refrigerator liner is to keep warm and maintain the internal temperature of the refrigerator. Therefore, in order to obtain a good insulation effect, the refrigerator liner needs to be accurately installed. In the prior art, the refrigerator liner is mainly installed through guide rails.

[0003] However, the existing punching accuracy of the guide rail mounting holes on the refrigerator box is poor, which generally leads to the following problems: 1. The deviation is large and the guide rail cannot be installed into the guide rail mounting groove; 2. The gap around the guide rail is poorly uniform, affecting the product appearance; 3. Frequent rework leads to increased waste; 4. The labor intensity of workers is high. Under this background, the process department requires operators to measure each box with a caliper or use a homemade inspection tool for inspection to ensure that the position of each box rail mounting hole is accurate. Although this process can enable the refrigerator box to be accurately installed, this process method seriously affects production efficiency and increases the labor intensity of operators, resulting in production bottlenecks in the blister production line and increased operator mobility.

[0004] Therefore, how to achieve efficient and accurate installation of the guide rails of the refrigerator is an important technical problem that needs to be solved urgently. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a refrigerator guide rail installation device, which can efficiently and accurately install the guide rail of the refrigerator by arranging punching marking points and self-checking positions.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0007] The present application provides a refrigerator rail installation device, comprising:

[0008] A guide rail mounting plate, wherein the guide rail mounting plate is provided with a guide rail mounting groove, and the guide rail mounting groove is formed with punching marking points;

[0009] The guide rail is detachably mounted on the guide rail mounting plate, and positioning pins and buckles are provided at positions on the guide rail corresponding to the punching mark points. The positioning pins and the buckles are matched and connected with the punching mark points so that the guide rail is installed in the guide rail mounting groove. The guide rail is used to support a refrigerator storage box so that the refrigerator storage box can be pushed and pulled by the guide rail.

[0010] Optionally, in some embodiments of the present application, the punching mark point presents a raised structure in the guide rail mounting groove, and the raised direction of the punching mark point is the direction of the guide rail mounting plate toward the refrigerator storage box.

[0011] Optionally, in some embodiments of the present application, the raised height of the punching mark point is 0.3mm-0.6mm.

[0012] Optionally, in some embodiments of the present application, the punching mark point is composed of a group of mounting holes, and a punching mark boss is provided on the mounting hole, and the shape of the punching mark boss is adapted to the shape of the positioning pin and the buckle so that the guide rail is connected to the guide rail mounting groove;

[0013] In the above, when the punching mark point is cut, the position corresponding to the punching mark boss is the mounting hole, and the positioning pin and the buckle are connected through the mounting hole.

[0014] Optionally, in some embodiments of the present application, a plurality of self-inspection positions are further provided in the guide rail mounting groove, and the plurality of self-inspection positions are located on both sides of the punching mark point. The self-inspection positions are provided with transverse ribs and vertical ribs, and the transverse ribs and the vertical ribs present a concave structure in the guide rail mounting groove.

[0015] Optionally, in some embodiments of the present application, the indentation depths of the transverse ribs and the vertical ribs are both 1 mm-2 mm.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model can visually check whether the punching accuracy of the guide rail mounting hole meets the design requirements by setting the punching mark point and the self-checking position, thereby improving production efficiency and reducing the labor intensity of workers' inspection. After the guide rail mounting hole is punched, the guide rail mounting hole is visually checked according to the punching mark and the self-checking position to judge whether the punching accuracy meets the requirements. If the punching mark boss is completely punched and falls off, the punching accuracy meets the requirements. On the contrary, it does not meet the requirements and it is necessary to readjust the punching mold until the punching mark is completely punched and falls off. When the punching mark is completely punched and falls off, the self-checking position is further used to visually check whether the punching tolerance directions of the left and right guide rail mounting holes are consistent, so as to avoid the guide rail mounting hole having a positive difference on one side and a negative difference on the other side, thereby avoiding the left and right guide rails being not in the same horizontal plane after installation or having a large distance between the front and the back.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0026] Specifically, Figure 1 As shown, an embodiment of the present application provides a refrigerator guide rail installation device, which mainly includes a guide rail installation plate 100 and a guide rail 200, wherein the guide rail installation plate 100 is a part of the refrigerator box, and the guide rail installation plate 100 is formed by the guide rail installation groove 110 and the punching mark point 111 and the self-inspection position 112. In the embodiment of the present application, for the convenience of description, the area about the guide rail installation groove 110 and the punching mark point 111 and the self-inspection position 112 in the refrigerator box is described as the guide rail installation plate 100, so that the structure can be clearly displayed.

[0027] In the embodiment of the present application, the guide rail 200 is installed in the guide rail mounting groove 110 on the guide rail mounting plate 100, so that the guide rail 200 can be removably fixed on the refrigerator box. The function of the guide rail 200 is to support the refrigerator storage box. The refrigerator storage box can be pushed and pulled in the refrigerator box by cooperating with the guide rail 200, so that the items in the storage box can be refrigerated or frozen.

[0028] To facilitate the installation of the guide rail 200, a positioning pin 210 and a buckle 220 are provided at the position corresponding to the punching mark point 111 on the guide rail 200. The positioning pin 210 and the buckle 220 can enable the guide rail 200 to be installed on the box. Specifically, in the embodiment of the present application, there are three punching mark points 111, namely a positioning pin installation point and two buckle installation points. The positioning pin installation point cooperates with the positioning pin 210, and the buckle installation point cooperates with the buckle 220 to install the guide rail 200 on the guide rail mounting plate 100, that is, on the box. Among them, the positioning pin installation point is mainly used to position the guide rail 200 to avoid misinstallation of the guide rails 200 on the left and right sides of the refrigerator, and the positioning pin 210 can maintain the assembly accuracy of the guide rail 200. The buckle installation point is mainly used to fix the guide rail 200 to prevent the guide rail from falling off during installation in the box.

[0029] The positioning pin 210 and the buckle 220 are both connected through the mounting hole 1111 .

[0030] Among them, in the traditional structure, the guide rail mounting groove 110 is generally provided with a mounting hole 1111, and the installation is performed through the matching relationship between the guide rail 200 and the mounting hole 1111. After the punching of the guide rail mounting hole 1111 of the traditional structure box liner is completed, the operator needs to use a gauge or a caliper to detect the punching holes on each box liner, so the punching production efficiency is low and the operator's detection labor intensity is high. In the present application, a punching mark boss 1112 corresponding to the positioning pin 210 and the buckle 220 is provided in the guide rail mounting groove 110, and the punching mark boss 1112 can be used by the operator to visually check whether the position of the guide rail mounting hole 1111 is correct. The shape of the punching mark boss 1112 is the same as the shape of the guide rail mounting hole 1111, and the punching mark boss 1112 is a part of the punching mark point 111, that is, the punching mark point 111 is mainly composed of the mounting hole 1111 and the punching mark boss 1112.

[0031] The protruding direction of the punching mark point 111, that is, the protruding direction of the punching mark boss 1112, is the direction of the guide rail mounting plate 100 toward the refrigerator storage box.

[0032] Among them, the punching mark boss 1112 protrudes 0.3mm-0.6mm in the direction of the center of the box, the size of the punching mark point 111 is offset by equidistant reduction from the guide rail mounting hole 1111 inward (that is, the punching mark size is smaller than the size of the mounting hole 1111), and the single-side spacing is preset to be 0.3mm-0.6mm smaller. After the box is punched, the operator only needs to visually check whether the punching mark boss 1112 exists on the box to determine whether the accuracy of the mounting hole 1111 is qualified. If the punching mark boss 1112 is completely punched out, that is, there is no punching mark boss in the guide rail mounting hole 1111, then the punching accuracy is qualified; if the punching mark boss 1112 has residue around the mounting hole 1111, that is, no matter which side of the mounting hole 1111 has residue, it is unqualified, and the residue indicates that the punching accuracy is unqualified, and the punching die needs to be adjusted until the punching mark boss 1112 is completely punched out. In order to prevent the left and right guide rails 200 from being not aligned in the same horizontal plane and depth direction due to the fact that one side of the left and right guide rail mounting holes 1111 has a positive difference in punching accuracy while the other side has a negative difference in punching accuracy under the premise of satisfying the punching accuracy, the embodiment of the present application is provided with a self-inspection position 112 around the guide rail mounting hole 1111, so that the operator can visually inspect the distance between the left and right guide rail mounting holes 1111 and the self-inspection position 112 to determine whether the tolerance direction of the left and right guide rails 200 is consistent.

[0033] The self-inspection position 112 is provided with a plurality of vertical ribs 1122 and transverse ribs 1121, which are respectively located on both sides of the guide rail mounting hole 1111, and the transverse ribs 1121 and the vertical ribs 1122 present a concave structure in the guide rail mounting groove 110. The concave structure can prevent the rib protrusion from blocking the installation of the guide rail 200. The main function of the ribs is to form a judgment identification area. The transverse rib 1121 can determine whether the guide rail 200 is installed in the center, and the vertical rib 1122 can determine whether the position of the guide rail 200 is correct. At the same time, it is convenient for the operator to randomly check and measure the specific size of the guide rail mounting hole 1111 after punching. The depth of the transverse ribs 1121 and the vertical ribs 1122 are both 1mm-2mm, which can provide a good judgment identification area, which is conducive to improving the forming clarity and convenient for the operator to visually observe the punching position.

[0034] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
