Description

Technical Field

[0001] The utility model relates to the technical field of door frame manufacturing, in particular to a spliced ​​door frame. Background Art

[0002] The door frame mainly includes a vertical vertical bar and a horizontal head frame. The door frame is embedded in the wall and is used to install the door leaf. The door frame is generally made of wood or metal. For the door frame made of metal materials, when the wall thickness is large, if it is produced as an integral door frame, it will increase the labor intensity of the workers and also have higher requirements on the production equipment. Although it is easier to process the door frame by welding, it is still more troublesome in the transportation and handling process, occupies a large space, and has low transportation efficiency.

[0003] Some existing technologies are to first process the two vertical rails and the head frame and transport them, and then assemble and install the two vertical rails and the head frame into the door opening when in use. However, the existing spliced ​​door frames have more or less the following shortcomings: low structural strength, greater assembly difficulty, and more troublesome installation into the door opening, etc., and the current wooden door frames basically adopt a single-layer wooden structure, and their sound insulation effect is poor. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a spliced ​​door frame which is convenient for splicing and installing the door frame and can achieve sound insulation of the door frame.

[0005] The utility model is implemented by the following method: a spliced ​​door frame, comprising a first door frame plate, a second door frame plate, a third door frame plate and a fourth door frame plate, wherein the first door frame plate, the second door frame plate, the third door frame plate and the fourth door frame plate are connected via a connecting piece to form a door frame body, and the inner side surfaces of the first door frame plate, the second door frame plate, the third door frame plate and the fourth door frame plate are provided with a first sound insulation layer.

[0006] Furthermore, the connecting member includes an extension plate, and the left and right ends of the first door frame plate and the fourth door frame plate are both extended outward with an extension plate, and a limiting groove is provided at the end of the upper surface of the extension plate, and the upper and lower surfaces of the second door frame plate and the third door frame plate are both provided with connecting grooves corresponding to the extension plate, and a first threaded hole is provided on the connecting groove, and a second sound insulation layer is provided on the right side of the extension plate, and a second threaded hole corresponding to the first threaded hole is provided on the extension plate, a third sound insulation layer is provided on the inner bottom surface of the connecting groove, and an opening matching the limiting groove is provided on the upper surface of the connecting groove.

[0007] The beneficial effects of the utility model are as follows: the utility model adds a connecting piece and a first sound insulation layer to the device, which can realize the installation and splicing of the door frame, and is convenient for transportation and handling. Through the effect of the first sound insulation layer, the sound insulation effect of the door frame can be achieved; the utility model has a simple structure and is easy to operate, and can effectively save manpower and material resources and improve work efficiency.

[0010] The utility model is further described below in conjunction with the accompanying drawings.

[0011] See also Figure 1 and Figure 2 As shown, the utility model provides an embodiment: a spliced ​​door frame, comprising a first door frame plate 1, a second door frame plate 2, a third door frame plate 3 and a fourth door frame plate 4, wherein the first door frame plate 1, the second door frame plate 2, the third door frame plate 3 and the fourth door frame plate 4 are connected via a connecting member 5 to form a door frame body, and a first sound insulation layer 6 is provided on the inner side of the first door frame plate 1, the second door frame plate 2, the third door frame plate 3 and the fourth door frame plate 4. The connecting member 5 enables connection between the plates, thereby facilitating splicing and installation of the door frame, and then the first sound insulation layer 6 enables sound insulation effect of the door frame.

[0012] Please continue reading Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the connecting member 5 includes an extension plate 51, and the first door frame plate 1 and the fourth door frame plate 4 are both extended outwards with an extension plate 51 at both left and right ends, and a limiting groove 52 is provided at the end of the upper surface of the extension plate 51, and the second door frame plate 2 and the third door frame plate 3 are both provided with a connection groove 53 corresponding to the extension plate 51 on the upper and lower surfaces, and a first threaded hole 54 is provided on the connection groove 53, and a second sound insulation layer 55 is provided on the right side of the extension plate 51, and a second threaded hole 56 corresponding to the first threaded hole 54 is provided on the extension plate 51, and a third sound insulation layer 57 is provided on the inner bottom surface of the connection groove 53, and an opening 58 matching with the limiting groove 52 is provided on the upper surface of the connection groove 53. Through the matching of the extension plate 51 and the connection groove 53, the connection and fixation of the first door frame plate 1 and the fourth door frame plate 4 can be realized, and the sound insulation effect of the door frame can be achieved through the second sound insulation layer 55 and the third sound insulation layer 57.

[0013] The sound insulation layer in the present invention is a prior art, which can be clearly understood by those skilled in the art and will not be described in detail here.

[0014] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
