Description

Technical Field

[0001] This utility model belongs to the technical field of container accessories, and more specifically, it relates to anti-theft electroplated galvanized door hinges for containers. Background Technology

[0002] The anti-theft electro-galvanized door hinge is a key component used in container doors. It mainly connects the container door to the container body, allowing the door to open and close smoothly. Structurally, the door hinge is generally installed on the edge of the container door and at the corresponding position on the container body. It is a hinge-like device that connects the two parts through a pivot pin, allowing the door to rotate around the pivot. To prevent the hinge from rusting and corroding and to extend its service life, the hinge is usually electroplated. Electro-galvanizing is the process of forming a zinc layer on its surface.

[0003] The existing application number is CN03148121.3. This invention discloses a container with a safety door hinge and the safety door hinge, including a container body, a container door, and a safety door hinge. The safety door hinge is set between the container body and the container door. The safety door hinge includes a hinge body, two door ears, and a through pin. The hinge body is connected to the container door, and the door ears are connected to the container body. The through pin passes through the door ears and the inner pin hole of the hinge body to form a hinge structure. A pin cap is provided at the upper end of the through pin, and the pin cap extends to form a locking part. A stop is also provided above the pin cap. The stop is installed on the hinge body or the container door and rotates with the container door between the closed and open positions. The locking part and the stop form a locked state in the closed position of the container door and an open state in the open position of the container door.

[0004] Based on the above, the existing container security door hinges are prone to wear of the galvanized layer on the surface of the hinges due to friction between the hinges and the side panels during long-term use. In order to extend the service life of the hinges, users need to add lubricating oil to the hinges frequently for maintenance. However, the operation of adding lubricating oil regularly is cumbersome and affects the performance of the hinges. Utility Model Content

[0007] The container anti-theft electro-galvanized door hinge includes a fixed mounting plate, a mounting connecting shaft, a mounting connecting side plate, mounting bolts, a mounting lubrication box, a mounting anti-loosening mechanism, and a maintenance lubrication mechanism. The mounting connecting shaft is fixedly connected between two sets of fixed mounting plates.

[0009] Furthermore, the installation anti-loosening mechanism also includes: anti-loosening limiting sliders and anti-loosening compression springs; two sets of anti-loosening limiting sliders are provided, and the two sets of anti-loosening limiting sliders are slidably connected to the front of the anti-loosening groove, and a "C"-shaped groove structure is provided on the right side of both sets of anti-loosening limiting sliders; two sets of anti-loosening compression springs are provided, and the two sets of anti-loosening compression springs are fixedly connected to the left side of the anti-loosening limiting sliders, and the left end of both sets of anti-loosening compression springs is fixedly connected to the installation connection side plate.

[0010] Furthermore, the maintenance and lubrication mechanism includes: a lubrication adding groove and a lubrication connecting groove; the lubrication adding groove is provided in multiple sets, and the multiple sets of lubrication adding grooves are respectively opened on the outside of the mounting connecting shaft; the lubrication connecting groove is opened inside the mounting connecting shaft, and the lubrication connecting groove communicates with the lubrication adding groove.

[0011] Furthermore, the maintenance and lubrication mechanism also includes: a lubrication limiting disc, a lubrication driving component, a lubrication transmission slider, and a lubrication driving rod; the lubrication limiting disc is rotatably connected above the fixed mounting plate, and a circular hole structure is opened on the inner side of the lubrication limiting disc, with the upper end face of the lubrication limiting disc in frictional contact with the lower end of the lubrication box; the lubrication driving component is fixedly connected to the left side of the lubrication limiting disc, and a rectangular groove structure is opened on the inner side of the lubrication driving component; the lubrication transmission slider is slidably connected to the left side of the fixed mounting plate; the lubrication driving rod is fixedly connected to the upper end of the lubrication transmission slider, and the upper end of the lubrication driving rod is located inside the rectangular groove of the lubrication driving component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model, through the installation of an anti-loosening mechanism, allows the anti-loosening limiting slider to slide to the left, and then the mounting bolt is passed through the mounting connection side plate and connected to the container door. After the mounting bolt is installed, the anti-loosening limiting slider is released. Under the action of the anti-loosening compression spring, the anti-loosening limiting slider achieves the limitation of the mounting bolt, preventing the mounting bolt from rotating during use, avoiding the mounting bolt from loosening, and ensuring the installation stability of the hinge lug.

[0015] This utility model, through the setting of a maintenance lubrication mechanism, allows the anti-theft door to rotate, causing the mounting and connecting side plate to rotate. The rotation of the mounting and connecting side plate pulls the lubrication trigger rod, which in turn moves the lubrication transmission slider forward. This forward movement of the lubrication transmission slider moves the lubrication drive rod forward, causing it to swing. The swinging of the lubrication drive rod then causes the lubrication limiting disc to rotate. Once the circular hole of the lubrication limiting disc aligns with the circular hole of the lubrication box, the lubricating oil inside the lubrication box flows into the lubrication addition groove through the lubrication connecting groove. This achieves lubrication maintenance of the hinge, avoiding manual maintenance of the hinge, facilitating maintenance operations, reducing the frequency of maintenance, ensuring stable use of the hinge, and improving its performance.

After the mounting bolt 4 is installed, release the anti-loosening limit slider 102. Under the action of the anti-loosening compression spring 103, the anti-loosening limit slider 102 achieves the limitation of the mounting bolt 4, preventing the mounting bolt 4 from rotating during use, avoiding the mounting bolt 4 from loosening, and ensuring the installation stability of the hinge lug. Example 2:

[0028] This utility model provides anti-theft electro-galvanized door hinges for containers, based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a maintenance and lubrication mechanism, which is located above the fixed mounting plate 1.

[0029] The maintenance and lubrication mechanism includes: a lubrication adding groove 501, a lubrication connecting groove 502, a lubrication limiting plate 503, a lubrication driving component 504, a lubrication transmission slider 505, a lubrication driving rod 506, a lubrication reset spring 507, and a lubrication trigger rod 508.
