DETAILED DESCRIPTION

[0034] The utility model will be further described below in combination with the drawings and specific implementation scheme:

[0035] As Figures 1-8As shown, the embodiment provides a distance-adjustable corner code, which comprises an inner corner block 1 and an outer corner block 2 combined together, and the inner corner block 1 and the outer corner block 2 are movably connected, so that the distance between the inner corner block 1 and the outer corner block 2 can be changed, that is, the distance between the inner corner block 1 and the outer corner block 2 can be adjusted as needed.

[0036] Exemplarily, the inner corner block 1 and the outer corner block 2 are both made of aluminum profile.

[0037] Exemplarily, the movably connecting of the inner corner block 1 and the outer corner block 2 includes the following two connecting modes, that is, the movably connecting of the inner corner block 1 and the outer corner block 2 can adopt any one of the following two connecting modes:

[0038] Mode 1: The inner corner block 1 and the outer corner block 2 are arranged at intervals, that is, there is no connection between the inner corner block 1 and the outer corner block 2, and the inner corner block 1 and the outer corner block 2 can be stacked together, so that the inner corner block 1 and the outer corner block 2 can be directly abutted together. When it is needed to separate the inner corner block 1 and the outer corner block 2, any one of the inner corner block 1 and the outer corner block 2 can be directly taken out to separate the inner corner block 1 and the outer corner block 2.

[0039] Mode 2: The inner corner block 1 and the outer corner block 2 are connected by an elastic member, and the two ends of the elastic member are connected to the inner corner block 1 and the outer corner block 2 respectively, so that the distance between the inner corner block 1 and the outer corner block 2 can be adjusted, and the distance includes the case that the inner corner block 1 and the outer corner block 2 can be attached together.

[0040] Exemplarily, the inner corner block 1 comprises a first inner corner block part 11 and a second inner corner block part 12, and the first inner corner block part 11 and the second inner corner block part 12 are connected together. The outer corner block 2 comprises a first outer corner block part 21 and a second outer corner block part 22, and the first outer corner block part 21 and the second outer corner block part 22 are connected together. When the inner corner block 1 and the outer corner block 2 are combined together, the first inner corner block part 11 and the first outer corner block part 21 are combined together to form a first end part of the distance-adjustable corner code, and the second inner corner block part 12 and the second outer corner block part 22 are combined together to form a second end part of the distance-adjustable corner code.

[0041] In actual use, when it is needed to connect the first cut profile 8 and the second cut profile 9 through the distance-adjustable corner code, the first end part can be extended into the cavity of the first cut profile 8, and the second end part can be extended into the cavity of the second cut profile 9, so as to connect the first cut profile 8 and the second cut profile 9 together through the distance-adjustable corner code.

[0042] Exemplarily, according to the angle size of the included angle formed by connecting the first cut profile 8 and the second cut profile 9 together, the first end part and the second end part are matched with the same angle of the included angle. For example, when it is needed to assemble the first cut profile 8 and the second cut profile 9 into a right angle, that is, the included angle is 90°, as shown in Figures 5-8The first cut profile 8 and the second cut profile 9 are assembled into a right angle. For this purpose, the first end portion and the second end portion are arranged at an angle of 90°, i.e. the first end portion and the second end portion are connected together at right angles, so that the distance-adjustable corner brace is in the shape of an L. Correspondingly, the first outer corner block portion 21 and the second outer corner block portion 22 are assembled into a right angle, and the inner corner block 1 is also in the shape of an L. Similarly, the first outer corner block portion 21 and the second outer corner block portion 22 are also assembled into a right angle, and the outer corner block 2 is also in the shape of an L.

[0043] The first outer corner block portion 21 and the second outer corner block portion 22 of the outer corner block 2 are each provided with a second threaded hole 4, which is a through hole, i.e. the second threaded hole 4 on the first outer corner block portion 21 penetrates through the first outer corner block portion 21 in the direction in which the first outer corner block portion 21 points to the first inner corner block portion 11, and the second threaded hole 4 on the second outer corner block portion 22 penetrates through the second outer corner block portion 22 in the direction in which the second outer corner block portion 22 points to the second inner corner block portion 12.

[0044] The second threaded hole 4 is fitted with a second screw 7, which passes through the first cut profile 8 or the second cut profile 9 and then passes through the second threaded hole 4, so that one end of the second screw 7 that passes through the second threaded hole 4 abuts against the inner corner block 1, and the inner corner block 1 can be driven away from the outer corner block 2, so as to adjust the distance between the inner corner block 1 and the outer corner block 2. Thus, the distance between the inner corner block 1 and the outer corner block 2 can be adjusted by tightening or loosening the second screw 7 in the second threaded hole 4, so that the distance-adjustable corner brace can be adapted to cut profiles of different sizes, i.e. the distance between the outer side surface of the outer corner block 2 and the outer side surface of the inner corner block 1 is adapted to the width of the cavity into which the distance-adjustable corner brace extends.

[0045] In the case that the second screw 7 is not strictly screwed along the central axis of the second thread hole 4, i.e. the second screw 7 is not completely perpendicular to the second thread hole 4 at 90°, but is screwed at an angle to the second thread hole 4, in this case, in order to ensure that the second screw 7 is screwed into the second thread hole 4 and the end of the second screw 7 can abut against the inner corner block 1, and the inner corner block 1 and the outer corner block 2 can abut against the two inner side walls of the cavity of the cutting profile respectively, the length of the thread of the second screw 7 is greater than the length of the second thread hole 4, and is also greater than the difference between the width a of the cavity of the cutting profile and the thickness b of the adjustable angle bracket in the combined state of the inner corner block 1 and the outer corner block 2, i.e. the length of the thread of the second screw 7 > a-b, so that the end of the second screw 7 can abut against the inner corner block 1 after the second screw 7 is screwed into the second thread hole 4 and passes through the second thread hole 4, and the inner corner block 1 is driven to the one inner side wall of the cavity of the cutting profile, and similarly, the outer corner block 2 can also abut against the other opposite inner side wall of the cavity of the cutting profile under the reaction force, so that the adjustable angle bracket can be well clamped in the cavity of the cutting profile to adapt to cutting profiles of different cavity widths.

[0046] According to the needs, the length of the thread of the second screw 7 also needs to be less than a preset length threshold, for example, the preset length threshold is set to 5mm (millimeters), and the length of the thread of the second screw 7 needs to be less than 5mm in addition to meeting the above conditions.

[0047] For example, the outer corner block 2 is also provided with a material reducing hole 5 to save materials and reduce the weight of the outer corner block 2, thereby reducing the cost and making the adjustable angle bracket lightweight.

[0048] For example, the outer corner block 2 is also provided with a first thread hole 3, which can be a through hole or a blind hole. The first thread hole 3 corresponds in position to the material reducing hole 5, and the first thread hole 3 is located on one side of the material reducing hole 5.

[0049] It also includes a first screw 6 matched with the first thread hole 3, and the first screw 6 is also provided with a thread so that the first screw 6 can be screwed into the first thread hole 3. By screwing the first screw 6 into the first thread hole 3, the first screw 6 makes the first outer corner block part 21 and the second outer corner block part 22 of the outer corner block 2 tightly combined with the first cutting profile 8 and the second cutting profile 9 respectively, so that the first cutting profile 8 and the second cutting profile 9 are spliced more tightly. Figure 5Under the action of the first screw 6, the 45° inclined end face on the first cutting profile 8 is more closely fitted with the 45° inclined end face on the second cutting profile 9.

[0050] It should be noted that without the first screw 6 and the first threaded hole 3, the first cutting profile 8 and the second cutting profile 9 can be connected together only by the second screw 7 and the second threaded hole 4. The cooperation of the first screw 6 and the second threaded hole 4 plays a role of more closely fitting the first cutting profile 8 and the second cutting profile 9.

[0051] For example, the joint 23 of the first outer corner block 21 and the second outer corner block 22 is provided with a notch 231, which is located at one end of the joint 23 close to the inner corner block 1. The joint of the first inner corner block 11 and the second inner corner block 12 is provided with a protrusion 13, which is matched with the notch 231, so that the protrusion 13 is slidably embedded in the notch 231. In order to avoid the inner corner block 1 and the outer corner block 2 being separated at will and thus the matching inner corner block 1 and outer corner block 2 cannot be found, when the inner corner block 1 and the outer corner block 2 are in the combined state, the protrusion 13 is embedded in the notch 231, so as to clampingly connect the inner corner block 1 and the outer corner block 2 together.

[0052] In actual use, first, the second screw 7 is threadedly connected to the second threaded hole 4, and when the end of the second screw 7 abuts against the inner corner block 1 and the inner corner block 1 and the outer corner block 2 are in contact with the two opposite inner side walls of the cavity of the cutting profile, the second screw 7 is stopped from being screwed. Then, the first screw 6 is threadedly connected to the first threaded hole 3, so that the first cutting profile 8 and the second cutting profile 9 are closely fitted together, and the first screw 6 is completely tightened (cannot be screwed further), and then the second screw 7 is continued to be screwed until the second screw 7 is also completely tightened on the second threaded hole 4. Of course, according to needs, corner glue can also be applied for processing, so as to further enhance the stress strength of the cutting profile connected together. The corner glue is a prior art, and thus will not be described here.

[0053] The utility model can adjust the spacing between the outer corner block 2 and the inner corner block 1, so as to adapt to cutting profiles of different cavity sizes, and can well connect the first cutting profile 8 and the second cutting profile 9 together, so as to reduce the number of inventories and warehouse costs, improve production efficiency and development design efficiency, and have higher user experience.

[0054] The embodiments disclosed in the specification are only an example of one-sided features of the utility model, and the protection scope of the utility model is not limited to this embodiment, and any other functionally equivalent embodiment falls within the protection scope of the utility model. For those skilled in the art, according to the above described technical scheme and conception, other various corresponding changes and deformations can be made, and all these changes and deformations should belong to the protection scope of the utility model claim.
