Description

Technical Field

[0001] The utility model relates to the technical field of window frames, in particular to a window frame with a hidden bottom drainage device. Background Art

[0002] The problem of water accumulation at the bottom of the window frame is an unavoidable problem for most casement aluminum alloy doors and windows. This is because the opening and closing gap of casement aluminum alloy doors and windows cannot be completely sealed. If it is completely sealed, it will directly increase the damping feeling when the casement window is opened, making the window difficult to open;

[0003] At present, there are many drainage parts used at the bottom of window frames that can achieve the function of automatic drainage. However, due to impurities such as dust and sand on the outside of the window frame, it is easy to flow into the drainage parts along with rainwater, thus causing blockage. Secondly, due to the special installation structure of the drainage parts, once installed, when the inside is blocked and cannot drain, and silt removal is urgently needed at this time, the window frame body needs to be disassembled, and then the drainage structure needs to be disassembled, which is very troublesome.

[0004] Therefore, we improve the current window frame to meet the demand of dredging the window frame drainage parts without disassembling the window frame. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a window frame with a hidden bottom drainage device, which can clear the inside of the drainage piece without disassembling the window frame when the drainage piece of the window frame is blocked.

[0006] The technical problem to be solved by the utility model is achieved through the following technical solutions, including a window frame body and a drainage device, a mounting opening is opened at the bottom of the window frame body, the drainage device is embedded in the mounting opening on the window frame body, and the drainage device includes an outer cover, a drainage groove and a filter;

[0007] The outer cover is provided with a plurality of bolt holes I, one side of the outer cover is used for bolt fasteners to be screwed into the bolt holes I and is set as the outer cover mounting surface, and the other side can be used for the bolt fasteners in the bolt holes I to abut against the edge of the mounting opening and is set as the outer cover abutting surface;

[0008] The drainage groove is placed in the bottom of the window frame, and has a cavity inside. A drainage groove water inlet is vertically opened at the top for receiving the accumulated water in the window frame, and a drainage groove outlet is horizontally opened at the bottom facing the installation port for facilitating the drainage of the accumulated water. A bolt hole II corresponding to the position of the bolt hole I is opened at the edge of the drainage groove outlet.

[0009] One end of the filter element is hinged on the middle inner wall of the drain trough and is set as the filter element hinge end, and the other end does not contact the middle inner wall of the drain trough and is set as the filter element swing end. A filter element reset mechanism is set between the middle inner wall of the drain trough and the filter element hinge end.

[0010] Preferably, the initial swing direction of the filter element swing end of the filter element is vertically downward, and the final swing direction is horizontally toward the drain outlet of the drain trough, and the included angle of the swing stroke is 90°.

[0011] Preferably, the filter element resetting mechanism is a torsion spring.

[0012] Preferably, the outer cover is provided with a plurality of drainage holes.

[0013] Preferably, the filter element is provided with a plurality of filter holes.

[0014] Preferably, the bolt holes I and II are respectively provided with two pairs of upper and lower pairs.

[0015] Compared with the prior art, the beneficial technical effects of the utility model are:

[0016] (1) In order to desilt the drainage device at the bottom of the window frame without removing the window frame, we separated the outer cover and the drainage trough so that the outer cover can be removed from the outside of the window frame. In addition, since a filter is hinged in the drainage trough and a filter reset mechanism is installed between the filter and the drainage trough, the filter can be manually pulled to swing the swing end 90 degrees to clean the sludge and impurities blocked in the drainage trough to the outside of the drainage trough, thus avoiding the problem of having to dismantle the window frame before desilting.

[0017] (2) The drainage holes on the outer cover can not only drain water, but also block large impurities from entering the drainage groove and causing unnecessary blockage.

[0018] (3) The filter element is provided with filter holes, which can block impurities and dirt in the accumulated water during the discharge of the accumulated water. The personnel can then regularly clear the impurities and dirt to prevent the impurities and dirt from being discharged naturally and causing erosion to the outer wall at the bottom of the window frame.

DETAILED DESCRIPTION

[0024] The specific technical solutions of the present invention are further described below with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and do not constitute any limitation to the rights thereof.

[0025] Example 1, reference Figure 1-4 A window frame with a hidden bottom drainage device comprises a window frame body 1 and a drainage device. A mounting opening 2 is provided at the bottom of the window frame body 1. The mounting opening 2 is generally set as a square opening, and its size can be customized according to the size of the window frame. The drainage device is embedded in the mounting opening 2 on the window frame body 1. The drainage device comprises an outer cover, a drainage groove and a filter.

[0026] The outer cover is provided with a plurality of bolt holes Ⅰ3, one side of the outer cover is used for bolt fasteners to be screwed into the bolt holes Ⅰ3 and is set as the outer cover mounting surface 4, and the other side can be used for the bolt fasteners in the bolt holes Ⅰ3 to abut against the edge of the mounting opening 2 and is set as the outer cover abutting surface 5;

[0027] The outer cover is formed into a roughly square plate-shaped structure, and a plurality of drainage holes 6 are opened on the outer cover. The drainage holes 6 can be square holes opened at vertical intervals;

[0028] The drainage groove 7 is placed in the bottom of the window frame, and has a cavity inside. A drainage groove water inlet 8 is vertically opened at the top for receiving the accumulated water in the window frame, and a drainage groove outlet 9 is horizontally opened at the bottom facing the installation opening 2 for facilitating the drainage of the accumulated water. A bolt hole II 10 corresponding to the position of the bolt hole I 3 is opened at the edge of the drainage groove outlet 9.

[0029] The drain trough water inlet 8 and the drain trough outlet 9 can be formed as substantially square openings, and the design purpose is to facilitate the discharge of accumulated water;

[0030] In order to improve the connection stability between the outer cover and the drain trough 7, we respectively set two pairs of upper and lower bolt holes on the outer cover and the drain outlet 9 of the drain trough, that is, the bolt holes Ⅰ3 and the bolt holes Ⅱ10 are respectively set in two pairs of upper and lower pairs, so that the upper, lower, left and right four corners of the outer cover can be fixed to the four corners of the drain outlet 9 of the drain trough, so that the structural stability of the drainage device is stronger, and the loose structure or leakage is avoided;

[0031] One end of the filter element is hinged on the middle inner wall of the drain groove 7 and is set as the filter element hinge end 11, and the other end does not contact the middle inner wall of the drain groove 7 and is set as the filter element swing end 12;

[0032] The filter element is formed into a roughly square plate-shaped structure, and a plurality of filter holes 13 are opened on the filter element. The filter holes 13 can be transverse waist-shaped holes arranged at intervals from top to bottom.

[0033] In order to facilitate the removal of dirt blocked on the filter element, a filter element reset mechanism 14 is provided between the middle inner wall of the drain groove 7 and the filter element hinge end 11 of the filter element. The filter element reset mechanism 14 can be a torsion spring, and the initial swing direction of the filter element swing end 12 of the filter element is vertically downward, and the end swing direction is horizontally toward the drain outlet 9 of the drain groove, and the included angle of the swing stroke is 90°;

[0034] That is to say, when the drainage device needs to be desilted, it is only necessary to manually pull the swing end 12 of the filter element and push it outward 90° to remove the impurities and dirt around the swing end 12 of the filter element, which is convenient for daily maintenance of the drainage device and prevents the impurities and dirt from being naturally discharged from the drainage device and causing erosion to the wall under the window frame.

[0035] The use process of the window frame with a hidden bottom drainage device is as follows:

[0036] Installation: First, place the drain trough 7 at the installation opening 2 at the bottom of the window frame body 1, then place the outer cover outside the installation opening 2 at the bottom of the window frame body 1, and screw the bolt fasteners into the bolt holes Ⅰ3 and Ⅱ10, so that the outer cover and the drain opening 9 of the drain trough are tightly clamped on the installation opening 2 at the bottom of the window frame body 1;

[0037] Regular dredging: Without disassembling the window frame, we only need to disassemble the outer cover, and then manually pull the filter element swing end 12 and swing it 90 degrees, so as to clean the sludge impurities blocked in the drainage trough 7 to the outside of the drainage trough drain port 9, and the dredging process of the drainage trough 7 can be completed. After the dredging is completed, we can tightly connect the outer cover to the drainage trough drain port 9 through bolt fasteners.

[0038] Compared with the traditional integrated drainage parts, the window frame with the hidden bottom drainage device can dredge the drainage device at the bottom of the window frame without removing the window frame, which is more convenient to use.
