Abstract
The utility model discloses a square-tube joint for a supporting frame of a mosquito net. Both ends of the joint are inserted into square tubes which are connected. The utility model is characterized in that the cross section of the joint is also square; the side length of the cross section is in accordance with the side length of the inner diameter of each of the square tubes; the side length from the side length L1 of one end which is inserted into the square tubes to the side length L2 of the other end which is not inserted into the square tubes is gradually enlarged. The joint can be integral and also two joints can be nested. The side length L3 of a boss on the joint is slightly bigger than the inner diameter of each of the square tubes. Because of the sufficient contact of the joint with the structure and the inner diameters of the square tubes, the combination is firmer and the integral supporting frame can not be deformed. Simultaneously, because injection molding production is adopted, the processing more simple and convenient. The utility model is an ideal joint for a supporting frame of square tubes of a mosquito net.
Description
The utility model relates to a kind of pipe joint that the two stands square tube is joined that is used for, in particular for the square tube joint of mosquito net frame.
Mosquito net frame firmly be the key factor that directly influences the mosquito net practicality, therefore how to make each arm of mosquito net frame be combined, seek one preferably pipe joint be to be engaged in the problem that the mosquito net frame manufacturer considers.At present the mosquito net frame square tube of the known technology joint that is adopted that joins mostly is this form: respectively put a pipe and stretch out one section in the side cross tube end that need join, pipe and square tube riveted fixing, two pipe thicknesses differ, tubule stretches out one section of square tube, the tubule that exposes can insert in the extra heavy pipe just, thereby finishes joining of square tube.The shortcoming of said structure is built on the sand gapped between pipe and square tube, make the square tube of joining built on the sand, yielding, and processing is complicated.
The purpose of this utility model provides and a kind ofly makes square tube join firmly indeformable and process square tube joint simple, easy to use.
For achieving the above object, the utility model adopts following scheme: square tube joint cross section adopts square, and the internal diameter length of side of its cross section length of side and square tube adapts, and that end length of side to that end length of side near the square tube end of inserting square tube the inside strengthens gradually.
The square tube joint can adopt an integral body, and the joint medial side is grown up, and diminishes gradually to the two ends length of side.
The square tube joint also can adopt split type, adopts thickness two pipes, and it is square injection molded layers that cross section is arranged on two pipe external diameters, and extra heavy pipe can all be filled with in the outer end and not expose, and tubule exposes one section in the outer end, and the tubule that exposes can insert in the extra heavy pipe just.
After adopting said structure, touch because joint is fully tied with the square tube internal diameter, the centre is gapped not resemble pipe, thereby combination is more firm, makes entire bracket indeformable; Simultaneously owing to need not rivet, can direct forming, process relatively also easyly, it insertion square tube need only be got final product in the using process, easy to use.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the utility model one routine structural representation;
Fig. 2 is the another routine part-structure schematic representation of the utility model;
Fig. 3 is Fig. 2 embodiment another part structural representation.
The utility model shown in Figure 1 adopts integral molded plastic to be shaped, the joint cross section is square, middle cross section length of side L2 is big, the length of side diminishes gradually to two ends, wherein length of side L1 in two ends is slightly smaller than square tube internal diameter length of side L, middle length of side L2 is a bit larger tham square tube internal diameter length of side L, and the step about a 4mm also can be arranged in the middle of joint, and its length of side L3 is equal to or slightly greater than the square tube external diameter length of side.
Fig. 2, the utility model square tube joint shown in Figure 3 adopts thickness two pipes 1,2, injecting cross section on two pipe external diameters is square injection molded layers 3, one end cross section length of side L1 is slightly smaller than square tube internal diameter length of side L, the length of side that the other end cross section length of side L2 is a bit larger tham the square tube internal diameter, extra heavy pipe 1 is that the big slightly end of the length of side can all be filled with and do not expose in the outer end, tubule 2 exposes one section, the tubule 2 that exposes can insert in the extra heavy pipe 1 just, that end that the length of side is big slightly can have the step 5 about a wide 4mm of being, its length of side L3 is equal to or slightly greater than the square tube external diameter length of side, and it can play barrier effect in case joint all inserts in the square tube.
For joint is combined with square tube better, the striped 4 of protrusion also can be arranged in joint outer surface upper edge direction of insertion, this striped also play the guiding role when inserting.
Claims (6)
1. mosquito net frame square tube joint, insert in the square tube of joining at the two ends of joint, it is characterized in that, the joint cross section is square, the internal diameter length of side of its cross section length of side and square tube adapts, and that end cross section length of side to that end cross section length of side of inserting the square tube end of inserting square tube the inside strengthens gradually.
2. mosquito net frame square tube joint according to claim 1 is characterized in that this square tube joint is as a whole, the middle cross section length of side is big, the two ends cross section length of side is little, and wherein the cross section length of side in two ends is slightly smaller than the square tube internal diameter length of side, and the middle cross section length of side is a bit larger tham the square tube internal diameter length of side.
3. mosquito net frame square tube joint according to claim 2 is characterized in that, also can have a cross section length of side to be equal to or slightly greater than the step of the square tube external diameter length of side in the middle of joint.
