Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator handle design, and in particular to a connection strength detection device for refrigerator handle production. Background Art

[0002] Most of the existing refrigerators use hidden door handles, which are basically made of hard plastic. The handle is flush with the outer wall of the refrigerator door. The edge of the refrigerator door is grooved, and the handle covers the groove to provide space for manually opening the refrigerator door.

[0003] Since the material of the refrigerator handle is relatively thin, it may become loose when the refrigerator door is pulled hard. If the refrigerator handle has not been tested for strength before leaving the factory, it will affect the overall yield rate of the refrigerator. Utility Model Content

[0004] The purpose of the present application is to provide a connection strength detection device for refrigerator handle production to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0007] Preferably, a fixing rod is fixedly installed between the support plate and the fixing block, a fixing plate is fixedly installed on the outer wall of the fixing rod, the fixing plate is fixedly connected to the outer wall of the double-axis cylinder, and a pushing block is fixedly installed on the output end of the double-axis cylinder. The pushing block is made of plastic material, a contact plate is fixedly installed on one side of the pushing block, and the contact plate is installed on the side of the pushing block away from the fixing block.

[0008] Preferably, a limit plate is provided on the outside of the contact plate away from the dual-axis cylinder, the limit plate is fixedly connected to the outer wall of the support plate, and a contact switch is installed on the outer wall of the limit plate facing the contact plate. The limit plate is arranged parallel to the contact plate, and the installation position of the contact switch corresponds to the contact plate.

[0009] The beneficial effect of the utility model is that by providing a detection component, if the refrigerator handle and the connection are deformed, the contact plate will contact the contact switch, and the contact switch starts and stops the double-axis cylinder, and the operator observes the bending of the refrigerator handle. The detection component helps the refrigerator handle to quickly detect the strength of the handle before leaving the factory. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0015] like Figure 1-3 A connection strength detection device for refrigerator handle production shown in the figure includes a base 1 and a detection component installed on the base 1, the detection component includes a double-axis cylinder 7 and a fixed block 3, the fixed block 3 is fixedly installed on the base 1, a support plate 2 is fixedly installed on the side of the base 1 away from the fixed block 3, the double-axis cylinder 7 is installed on the side of the support plate 2 facing the fixed block 3, a threaded hole 4 is opened on the side of the fixed block 3 away from the support plate 2, and the output end of the double-axis cylinder 7 faces the fixed block 3.

[0016] A fixing rod 5 is fixedly installed between the support plate 2 and the fixing block 3, a fixing plate 6 is fixedly installed on the outer wall of the fixing rod 5, the fixing plate 6 is fixedly connected to the outer wall of the double-axis cylinder 7, and a push block 8 is fixedly installed on the output end of the double-axis cylinder 7. The push block 8 is made of plastic material, and a contact plate 9 is fixedly installed on one side of the push block 8, and the contact plate 9 is installed on the side of the push block 8 away from the fixing block 3.

[0017] A limit plate 10 is arranged outside the contact plate 9 on one side away from the dual-axis cylinder 7, the limit plate 10 is fixedly connected to the outer wall of the support plate 2, and a contact switch 11 is installed on the outer wall of the limit plate 10 facing the contact plate 9. The limit plate 10 is arranged parallel to the contact plate 9, and the installation position of the contact switch 11 corresponds to the contact plate 9.

[0018] Embodiment: The shape of the fixing block 3 is consistent with the internal shape of the refrigerator handle. The inner wall of the refrigerator handle is fitted with the outer wall of the fixing block 3. The hole on the handle is aligned with the threaded hole 4. The bolt is inserted into the refrigerator handle and the threaded hole 4 to fix the refrigerator handle and the fixing block 3. The thickness and material of the fixing block 3 correspond to the refrigerator door. At this time, the edge of the grip of the refrigerator handle is fitted with the pushing block 8 on the output end of the double-axis cylinder 7. Then the double-axis cylinder 7 is started, and the pushing block 8 pushes the edge of the refrigerator handle at a constant speed to test the strength of the refrigerator handle itself and the connection.

[0019] After a certain period of time, if the refrigerator handle is not deformed and the connection with the fixed block 3 is not loose, the contact plate 9 will not contact the contact switch 11 on the side wall of the limit plate 10. If the refrigerator handle and the connection are deformed, the contact plate 9 will contact the contact switch 11, and the contact switch 11 will start and stop the dual-axis cylinder 7, and the operator will observe the bending of the refrigerator handle.
