In addition, a plurality of fixing members 400 may be uniformly disposed around the circumference of the door frame body 200, so that a multi-point pressure can be applied to the door frame body 200, and the pressure is uniformly distributed, which is more advantageous in maintaining the sealing effectiveness.
When the door frame body 200 is detached, only the fixing assembly 400 is required to be operated reversely, and the description is omitted. Further, by the above-described operation method, the extension reed 440 can be engaged with the fourth cavity 209, and the door frame body 200 can be pulled out from the panel frame body 100 by the fixing unit 400, and at this time, the fixing unit 400 functions as a handle.
In the present embodiment, a retainer 450 is provided on the retraction operation member 430, and the retainer 450 abuts against the rear end surface of the hollow stud 410, so that an axial force can be transmitted between the hollow stud 410 and the retraction operation member 430.
In this embodiment, the outer side of the hollow stud 410 is provided with an external thread 411, the internal thread 422 of the fastening nut 420 is screwed with the external thread 411, the fastening nut 420 is preferably provided with a tab 421, and the fastening nut 420 and the hollow stud 410 can be screwed by the tab 421, so that the fixing assembly 400 is mounted.
In this embodiment, the rear end of the hollow stud 410 is provided with a first clamping portion 412, and the rear end of the retractable operating member 430 is provided with a second clamping portion 432. The cross sections of the first clamping portion 412 and the second clamping portion 432 may be quadrangular or hexagonal.
In one embodiment of the present invention, referring to fig. 10 and 11, the front end of the hollow stud 410 is uniformly provided with a plurality of second cylindrical blocking portions 414 around the central axis of the hollow stud 410, a gap is formed between the first cylindrical blocking portion 413 and the second cylindrical blocking portion, a telescopic reed 440 corresponding to the first cylindrical blocking portion 413 passes through the gap, and the free end of the first cylindrical blocking portion 413 is connected with the end of the second cylindrical blocking portion 414 through a shaft end fastening portion 415. The shaft end fastening portion 415 can provide support for the expansion reed 440 in the axial direction, and since the shaft end fastening portion 415 is closer to the hook body portion, a greater supporting force can be provided for the hook body portion.
In an embodiment of the present invention, referring to fig. 12, a radial through slot is formed on the dragging portion 431, and the second fixing portion 441 of the telescopic reed 440 passes through the through slot, and when the retractable operating member 430 is rotated, the dragging portion 431 can drive the second fixing portion 441 of the telescopic reed 440 to rotate, so that the telescopic reed 440 is retracted.
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the invention, but any modifications, equivalents, and simple improvements made within the spirit of the present invention should be included in the scope of the present invention.
