Description

Technical Field

[0001] The utility model relates to the technical field of door and window hinges, and more specifically to a tractor door and window hinge. Background Art

[0002] Hinge mechanism, i.e. hinge, is usually composed of two folding parts, which is a component that connects two parts of an object and enables them to move. Structures such as doors, windows, and cabinet doors that need to be opened and closed frequently usually have hinges set on the main structure to achieve their opening and closing functions. For example, the connection between the window sash and the window frame is achieved by fixing one side of the hinge to the window frame and the other side to the window sash, and then hinge the two. The hinge mechanism usually consists of two hinges, a shaft cylinder set on the two hinges, and a rotating shaft passing through the shaft cylinder.

[0003] In the existing tractor door and window hinge mechanisms, due to the high frequency of use, deformation may occur after repeated use for a period of time, and the rotating shaft may fall off, the hinge device may be damaged, and the rotating shaft resistance may increase after a period of use, and the door and window sashes may not open and close smoothly, so they need to be disassembled and repaired. However, since most of the current tractor door and window hinge mechanisms are fixed and locked with bolts, when the bolts are rusted due to air corrosion, the entire door and window hinge mechanism will be difficult to disassemble or cannot be disassembled. Therefore, this scheme proposes a tractor door and window hinge. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-3 The tractor door and window hinge comprises a shell 1 and a shell 2 6 fixed on the tractor door and window, the upper end of the shell 1 is provided with two mutually symmetrically distributed placement grooves 2, a protective shell 3 is rotatably connected between the inner walls of the two placement grooves 2, a connecting seat 4 is fixedly connected to the side end of the placement groove 2, the connecting seat 4 is located at the lower side of the protective shell 3, and a slot 5 is provided at the upper ends of the protective shell 3 and the connecting seat 4;

[0024] A slide groove 61 is provided at the upper end of the shell 2 6, and a rotating shaft 62 is slidably connected between the inner walls of the slide groove 61. Two symmetrically distributed positioning grooves 63 are provided at the upper end of the shell 2 6. The positioning grooves 63 and the slide groove 61 are connected to each other. A connecting rod 64 is fixedly connected to the side end of the rotating shaft 62, and two mutually symmetrical annular grooves 65 are provided at the upper end of the rotating shaft 62.

[0025] During use of the present solution, in order to avoid the phenomenon in the prior art that the bolts of the tractor door and window hinges are rusted and difficult to remove when they need to be replaced and disassembled due to damage, in the present embodiment, the existing tractor door and window hinges are improved by connecting the bolts and the buckles, so that after the tractor door and window hinges are subsequently worn, the hinges can be replaced without removing the bolts, thereby avoiding the phenomenon that the bolts fixing the door and window hinges are difficult to remove or cannot be removed due to rust, resulting in slow disassembly efficiency;

[0026] During use, the personnel can first fix the shell 1 to one side of the door and window, then rotate and open the protective shell 3, and then bend the connecting rod 64 to make it rotate out of the positioning groove 63, and then push the rotating shaft 62 to make the rotating shaft 62 continuously move into the slot 5 opened in the protective shell 3 and the connecting seat 4 until it is located at the lower side of the protective shell 3, and then rotate the protective shell 3 to make the protective shell 3 snap onto the upper side of the rotating shaft 62, thereby completing the installation of the hinge rotating shaft, and the other side of the door and window can be installed and connected with the connecting rod 64. At this time, since the rotating shaft 62 is limited while moving to the lower side of the protective shell 3, the rotating shaft 62 cannot move forward and backward, thereby completing the position limitation of the rotating shaft 62 inside the slot 5;

[0027] When personnel need to disassemble the door and window hinges, they can open the protective shell 3 so that the rotating shaft 62 is no longer limited by the protective shell 3. At this time, the rotating shaft 62 can move freely to be pulled out from the slot 5, thereby removing the door and window hinges, which is convenient for personnel to replace.

[0028] See also Figure 1-2 The lower end of the protective shell 3 is fixedly connected to two symmetrically distributed support seats 31 , and two positioning rods 32 are fixedly connected between the inner walls of the two support seats 31 , respectively. The two positioning rods 32 are respectively matched with the two annular grooves 65 .

[0029] During use of the present solution, when the rotating shaft 62 is inserted into the slot 5 and is located at the lower side of the protective shell 3, when the personnel flips over the protective shell 3, the support seat 31 is flipped synchronously until the support seat 31 contacts the base of the shell 1, and at the same time, the two positioning rods 32 are respectively engaged between the inner walls of the annular groove 65, thereby limiting the front and rear position of the rotating shaft 62 without affecting the free rotation of the rotating shaft 62.

[0030] See also Figure 1-3 The shape of the shell 1 is set as a fighter model shape.

[0031] Furthermore, one side end of the shell 1 and one side end of the shell 2 6 match each other and are serrated.

[0032] During use of the present invention, by setting the sides of the shell 1 and the shell 2 6 that are close to each other to fit together, the two can fit better when spliced ​​together and have a more beautiful appearance.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
