Description

Technical Field

[0001] This utility model relates to the field of container hinge technology, and in particular to an enhanced container hinge plate. Background Technology

[0002] Containers are important logistics tools. To facilitate loading and unloading of goods, a door is usually installed at the rear end of the container. The door is connected to the corner post of the rear frame of the container by hinges, so that the door can be opened and closed. Existing hinges usually include a hinge plate, a hinge pin, and two hinge ears. The two hinge ears are welded to the corner post and are distributed vertically. The hinge plate is fixed to the door and has a pin sleeve. The pin sleeve is placed between the two hinge ears. The hinge pin passes through the holes on the two hinge ears and the pin sleeve, pivotally connecting the hinge plate and the two hinge ears together. After long-term use, the inner surfaces of the hinge pin and the pin sleeve wear, resulting in an increased clearance between the hinge pin and the pin sleeve. In addition, due to the excessive weight of the container door itself, it is difficult to turn. To solve the above problems, an enhanced container hinge plate is provided, which reduces the clearance between the hinge pin and the pin sleeve by using a thrust bearing. Utility Model Content

[0003] In order to solve the problems mentioned in the background art, the present invention provides an enhanced container hinge plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An enhanced container hinge plate includes a hinge lug, a hinge pin, and a hinge plate. The hinge lug is fixedly connected to the container door frame, and the hinge plate is fixed to the container door. The hinge lug and the hinge plate are rotatably connected by the hinge pin.

[0006] A hinge pin is rotatably connected to a hinge lug. One end of the hinge pin is a threaded section, which is threadedly connected to a fixing sleeve. A first thrust bearing is provided on the circumferential sidewall of the hinge pin, located inside the hinge lug, and abuts against the lower end of the pin sleeve. A second thrust bearing is provided on the circumferential sidewall of the fixing sleeve, located inside the hinge lug, and abuts against the upper end of the pin sleeve.

[0007] Preferably, the other end of the hinge pin is provided with a lower limiting protrusion ring, and the end of the fixing sleeve located outside the hinge lug is provided with an upper limiting protrusion ring.

[0008] Preferably, the hinge plate has a pin sleeve on its side end, which is sleeved on the hinge pin and rotatably connected to the hinge pin.

[0009] Preferably, the hinge pin has a ball groove, and a ball is provided inside the ball groove, and the ball is in rolling connection with the pin sleeve.

[0010] Preferably, the hinge plate sidewall is provided with horizontal reinforcing ribs to increase the strength of the hinge plate, and the sidewall bends of the hinge plate are provided with reinforcing blocks to further enhance the strength of the hinge plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The first thrust bearing abuts against the lower end of the pin sleeve, and the second thrust bearing abuts against the upper end of the pin sleeve. At this time, the pressure of the hinge plate is applied to the end faces of the first and second thrust bearings. By rotating the first and second thrust bearings, the wear of the pin sleeve and the hinge pin can be reduced, avoiding the container door from becoming misaligned. Furthermore, the container door can be rotated with a smaller force because the pin sleeve and the hinge pin are connected by the thrust bearing.

[0013] 2. The hinge plate sidewall is horizontally reinforced with reinforcing ribs to increase the strength of the hinge plate. Reinforcing blocks are provided at the bends of the hinge plate sidewall to further enhance the strength of the hinge plate.

[0014] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, and connects the pin sleeve and hinge pin through a thrust bearing, reducing the wear of the pin sleeve and hinge pin. It has high social use value and application prospects. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Reference Figure 1-4 An enhanced container hinge plate includes a hinge ear 1, a hinge pin 2, and a hinge plate 3. The hinge ear 1 is fixedly connected to the container door frame, and the hinge plate 3 is fixed to the container door. The hinge ear 1 and the hinge plate 3 are rotatably connected through the hinge pin 2. The hinge plate 3 can rotate relative to the hinge ear 1, and the container door frame and the container door are rotatably connected.

[0025] The hinge pin 2 is rotatably connected to the hinge ear 1. One end of the hinge pin 2 is a threaded section 201, which is threadedly connected to a fixed sleeve 204. The other end of the hinge pin 2 is provided with a lower limit protrusion ring 202. The fixed sleeve 204 is provided with an upper limit protrusion ring 205 at the end located outside the hinge ear 1. During installation, the hinge pin 2 can be directly inserted into the pin hole on the hinge ear 1, and the fixed sleeve 204 is threadedly connected to the threaded section 201. At this time, the hinge pin 2 can be limited by the upper limit protrusion ring 205 and the lower limit protrusion ring 202, retaining only the degree of freedom of rotation.

[0026] The hinge plate 3 has a pin sleeve 31 on its side end. The pin sleeve 31 is sleeved on the hinge pin 2 and rotates to connect with the hinge pin 2, which facilitates the assembly and disassembly of the hinge plate 3.

[0027] A first thrust bearing 21 is provided on the circumferential side wall of the hinge pin 2, located inside the hinge ear 1. The first thrust bearing 21 abuts against the lower end of the pin sleeve 31. A second thrust bearing 26 is provided on the circumferential side wall of the fixed sleeve 204, located inside the hinge ear. The second thrust bearing 26 abuts against the upper end of the pin sleeve 31. At this time, the pressure of the hinge plate 3 is applied to the end faces of the first thrust bearing 21 and the second thrust bearing 26. By rotating the first thrust bearing 21 and the second thrust bearing 26, the wear of the pin sleeve 31 and the hinge pin 2 can be reduced, avoiding a certain degree of misalignment of the container door. Furthermore, the pin sleeve 31 and the hinge pin 2 can be connected through the thrust bearing, allowing the container door to be rotated with a smaller force.

[0028] Furthermore, a ball groove 22 is provided on the hinge pin 2, and a ball 221 is provided inside the ball groove 22. The ball 221 is in rolling connection with the pin sleeve 31. By providing the ball 221 between the hinge pin 2 and the pin sleeve 31, the friction between the hinge pin 2 and the pin sleeve 31 can be further reduced.

[0029] Furthermore, the hinge plate 3 has horizontally arranged reinforcing ribs 32 on its side wall to increase the strength of the hinge plate 3, and reinforcing blocks 33 are provided at the bends of the side wall of the hinge plate 3 to further enhance the strength of the hinge plate 3.

[0030] Working principle: During installation, align the pin sleeve 31 with the pin hole on the hinge ear 1, and directly insert the hinge pin 2 into the pin hole on the hinge ear 1. Thread the fixing sleeve 204 to the threaded section 201. At this time, the upper limit convex ring 205 and the lower limit convex ring 202 can limit the hinge pin 2. The first thrust bearing 21 abuts against the lower end of the pin sleeve 31, and the second thrust bearing 26 abuts against the upper end of the pin sleeve 31. At this time, the pressure of the hinge plate 3 is applied to the end faces of the first thrust bearing 21 and the second thrust bearing 26. By rotating the first thrust bearing 21 and the second thrust bearing 26, the wear between the pin sleeve 31 and the hinge pin 2 can be reduced, avoiding a certain degree of misalignment of the container door. Furthermore, the connection between the pin sleeve 31 and the hinge pin 2 through the thrust bearing allows the container door to be rotated with a smaller force.
