DETAILED DESCRIPTION

[0024] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0025] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0027] The embodiment of the utility model provides a conveniently adjustable upper hinge shaft installation structure, such as Figure 1-6As shown, the door body 10, the upper rotating seat 300 and the upper hinge shaft 370 are included. The top surface of the door body 10 is provided with a fixing groove 101, and the upper rotating seat 300 is embedded in the fixing groove 101, so as to achieve the effect of hiding the upper rotating seat 300. The top surface of the upper rotating seat 300 is provided with a hinge shaft installation groove 314 extending in the vertical direction, the lower end of the upper hinge shaft 370 is arranged in the hinge shaft installation groove 314 and can move along the hinge shaft installation groove 314, and the upper end of the upper hinge shaft 370 extends out of the hinge shaft installation groove 314 to be inserted into the rotating hole on the door frame. Since the hinge shaft installation groove 314 extends in the vertical direction, when the upper hinge shaft 370 moves in the hinge shaft installation groove 314, the upper hinge shaft 370 can move in the vertical direction relative to the upper rotating seat 300, thereby adjusting the position of the upper hinge shaft 370 in the vertical direction, so that the upper hinge shaft 370 can adapt to the rotating hole on the door frame, and can then be accurately inserted into the rotating hole.

[0028] The side of the upper rotating seat 300 is provided with an upper rotating seat embedding groove 302 communicating with the hinge shaft mounting groove 314, and the side of the door body 10 is provided with a first side mounting hole 104 communicating with the fixing groove 101, the first side mounting hole 104 is connected with the upper rotating seat embedding groove 302, and a locking member (not shown in the figure) is inserted through the first side mounting hole 104 and the upper rotating seat embedding groove 302, and the locking member is used to lock and fix the upper hinge shaft 370 in the hinge shaft mounting groove 314. Therefore, after the upper hinge shaft 370 is adjusted to a suitable position, the locking member can lock and fix the upper hinge shaft 370 in the hinge shaft mounting groove 314, so that the upper hinge shaft 370 maintains the adjusted position, and then is fastened to the upper rotating seat 300, to ensure the stable rotation of the door body 10. Of course, before the upper hinge shaft 370 is adjusted, the locking member is not used to lock and fix the upper hinge shaft 370. At the same time, since the side of the door body 10 is also provided with an opening, after the upper hinge shaft 370 is adjusted to a suitable position, the locking member can be inserted from the outside of the door body 10 to lock and fix the upper hinge shaft 370, which makes the operation more convenient.

[0029] In some embodiments, the upper hinge shaft 370 is provided with a through-hole 373, and the locking member passes through the through-hole 373 and is fixed on the upper rotating seat 300. After the locking member passes through the through-hole 373, the locking member will block the upper hinge shaft 370 from moving in the vertical direction, so that the upper hinge shaft 370 can be locked and fixed in the hinge shaft installation groove 314. During operation, it is only necessary to accurately align the locking member with the through-hole 373, which makes the operation simpler and more convenient. When it is necessary to release the locking of the upper hinge shaft 370, the locking member can be withdrawn from the through-hole 373, and the upper hinge shaft 370 can continue to move in the vertical direction.

[0030] Furthermore, the inner side wall of the fixing groove 101 opposite to the first side mounting hole 104 is provided with a second side mounting hole 105 that is docked with the upper rotating seat embedding groove 302, and the locking member passes through the upper rotating seat 300 and is fixed in the second side mounting hole 105. The locking member of this embodiment can not only lock and fix the upper hinge shaft 370, but also fasten the upper rotating seat 300 in the fixing groove 101, thereby achieving the effect of simultaneously fixing the upper rotating seat 300 and the upper hinge shaft 370 through the same fixing structure, which can simplify the fixing structure and facilitate quick assembly.

[0031] Furthermore, the door body 10 includes an inner frame 11, a fixing groove 101 is arranged in the inner frame 11, and a second side mounting hole 105 passes through the side wall of the inner frame 11. The locking member is a screw, a nut is sleeved on the screw, and the nut is located on the outer side of the inner frame 11, thereby, the upper rotating seat 300 is locked and fixed in the fixing groove 101 through the cooperation of the screw and the nut.

[0032] In some embodiments, an upper rotating seat insert 340 is embedded in the first side mounting hole 104 and the upper rotating seat embedding groove 302, and a locking member passes through the upper rotating seat insert 340. The upper rotating seat insert 340 can fill the first side mounting hole 104 and the upper rotating seat embedding groove 302, and the locking member passing through the upper rotating seat insert 340 is not easy to loosen in the first side mounting hole 104 and the upper rotating seat embedding groove 302, so that it can be fastened to the upper rotating seat 300, and the upper rotating seat insert 340 can block the opening, so that the appearance of the door body 10 is relatively beautiful.

[0033] In other embodiments, the locking member provided in the first side mounting hole 104 and the upper rotating seat embedding groove 302 can abut against the upper hinge shaft 370, and the upper hinge shaft 370 is clamped and fixed by the locking member and the side wall of the hinge shaft mounting groove 314, thereby locking and fixing the upper hinge shaft 370 in the hinge shaft mounting groove 314. Of course, the locking member can also be used to lock and fix the upper hinge shaft 370 in other ways.

[0034] In some embodiments, the upper hinge shaft 370 includes a shaft body 371 and a shaft body base plate 372 connected to the lower end of the shaft body 371, and the hinge shaft installation groove 314 includes a shaft body portion 315 and a base plate portion 316 connected to the shaft body portion 315. The lower end of the shaft body 371 is located in the shaft body portion 315, and the shaft body base plate 372 is arranged in the base plate portion 316. Since the area of ​​the shaft body base plate 372 is relatively larger, it is easy to open a hole in the shaft body base plate 372, and the locking member can easily lock and fix the upper hinge shaft 370. At the same time, the cooperation between the shaft body base plate 372 and the base plate portion 316 can limit the rotation of the shaft body 371 relative to the upper rotating seat 300, and the upper hinge shaft 370 can be stably maintained in the hinge shaft installation groove 314.

[0035] In some embodiments, the inner side wall of the fixed groove 101 is provided with an inner embedded plate 106 parallel to the width direction of the door body 10, and the upper rotating seat 300 is also provided with an embedded plug-in groove 313 adapted to the inner embedded plate 106; when the upper rotating seat 300 is embedded in the fixed groove 101, the inner embedded plate 106 is embedded in the embedded plug-in groove 313 to position the upper rotating seat 300 and limit its movement in the thickness direction of the door body 10.

[0036] In some embodiments, the inner side wall of the fixing groove 101 is also provided with a positioning panel 103 parallel to the thickness direction of the door body 10, and the upper rotating seat 300 is also provided with a positioning groove 320 adapted to the positioning panel 103; the positioning panel 103 is inserted into the positioning groove 320 to limit the movement of the upper rotating seat 300 relative to the door body 10 in the width direction of the door body 10, thereby ensuring the accuracy of its installation position.
