Description

Technical Field

[0001] This utility model relates to the field of hinge devices, and in particular to a hinge-type fixing device. Background Technology

[0002] In the field of refrigeration equipment manufacturing, hinge-type fixing devices are key components connecting the main body of the freezer to the door. Their installation stability and structural reliability directly affect the service life of the whole machine and the user experience. Traditional hinge fixing devices generally adopt direct welding or bolt hard connection methods, which have the following significant defects.

[0003] When using the device, the existing structure requires high installation precision, and the position needs to be repeatedly adjusted during assembly, which is particularly inefficient in mass production and makes it difficult to achieve rapid alignment. Furthermore, due to the frequent opening and closing of the hinges, stress is concentrated at the fixed point, which can easily lead to loose screws or deformation of the mounting plate, affecting the sealing performance and structural strength. At the same time, the traditional installation method occupies a lot of space, which is not conducive to the compact design of the overall structure of the freezer and also increases the difficulty of later maintenance. Although some existing hinge structures have attempted to alleviate the above problems by adding buffers or improving the bushing connection method, they still have not fundamentally solved the problem of balancing the matching stability between the mounting base and the cabinet, stress distribution and assembly convenience. Utility Model Content

[0004] The main objective of this invention is to provide a hinge-type fixing device that can effectively solve the technical problems raised in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hinge-type fixing device includes a lower bushing and an upper bushing. The lower bushing is located on one side of the upper bushing. A lower mounting plate is integrally formed on the outer side of the lower bushing, and an upper mounting plate is integrally formed on the outer side of the upper bushing. A shaft rod passes through the interior of the lower bushing. A spring top block is movably installed on the outer side of the shaft rod and inside the lower bushing. A limit groove is formed inside the upper bushing.

[0007] As a further embodiment of this utility model, the lower bushing and the upper bushing are arranged in parallel and movably connected.

[0008] As a further embodiment of this utility model, the lower mounting plate has a lower mounting screw hole inside, and the upper mounting plate has an upper mounting screw hole inside.

[0009] As a further embodiment of this utility model, a locking sleeve is embedded at the end of the upper bushing away from the lower bushing, and the shaft rod passes through the center of the upper bushing, with the locking sleeve and the end of the shaft rod being fixedly connected.

[0010] As a further embodiment of this utility model, the end of the spring top block is inserted into the upper seat bushing and connected with the limiting groove.

[0011] As a further embodiment of this utility model, the bottom surface of the lower mounting plate is connected in parallel to the freezer body, and the rear end surface of the upper mounting plate is connected in perpendicularly to the freezer door.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The lower mounting plate is placed in parallel and fits into the parallel mounting groove of the freezer body. It is then fixed with screws using the lower mounting screw holes, which effectively enhances the stability and mechanical strength of the installation, avoids loosening due to vibration or frequent opening and closing, and ensures stable and reliable installation. The parallel placement design allows the mounting plate to be quickly aligned with the groove of the freezer body, reducing the difficulty of adjustment during installation. The positioning is accurate and convenient, improving assembly efficiency. It is especially suitable for mass production or on-site installation scenarios. The parallel connection between the lower mounting plate and the freezer body reduces the additional space occupation, making the hinge part fit more closely with the overall structure of the freezer, achieving optimized structural compactness. This helps maintain the clean appearance of the equipment and the utilization of internal space. The installation method disperses the stress generated when the hinge rotates, reducing wear on individual connection points. At the same time, the screw fixing structure also facilitates later disassembly, maintenance, or replacement, improving durability and maintainability. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-9 As shown, a hinge-type fixing device is described; please refer to it carefully. Figures 1-9 It includes a lower bushing 1 and an upper bushing 4. The lower bushing 1 is located on one side of the upper bushing 4. A lower mounting plate 2 is integrally formed on the outer side of the lower bushing 1. An upper mounting plate 5 is integrally formed on the outer side of the upper bushing 4. A shaft rod 7 passes through the interior of the lower bushing 1.
