Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a horizontal bar 10 according to a preferred embodiment of the present invention includes: the horizontal bar comprises a horizontal bar body 100, two embedded boxes 300 and two supporting bars 200; first ends 201 of the two support rods 200 are respectively connected with two ends of the horizontal bar body 100, fixing parts 210 are respectively arranged at positions, close to the end parts, of second ends 202 of the two support rods 200 in a protruding mode towards the outside, and buffering cushions 220 are sleeved on the outside of the fixing parts 210; each of the pre-embedded boxes 300 is provided with a fixing cavity 301, the fixing cavity 301 is provided with an opening 302, the width of the opening 302 is smaller than that of the fixing cavity 301, the second end of each support rod 200 is inserted into the fixing cavity 301 of one of the pre-embedded boxes 300 through the opening, the side wall of the fixing cavity 301 is concavely provided with a fixing groove 302, the fixing portion 210 is arranged in the fixing groove 302, and the cushion pad 220 abuts against the side wall of the fixing groove 302.

In this embodiment, the horizontal bar body 100 is made of stainless steel, the support rod 200 and the embedded box 300 are made of metal, and the support rod 200 is of a cylinder structure, for example, the support rod 200 and the embedded box 300 are made of stainless steel. The first end of one support rod 200 is connected with the first end of the horizontal bar body 100, the first end of the other support rod 200 is connected with the second end of the horizontal bar body 100, and the second ends of the two support rods 200 are used for being inserted into the ground. The outside surface butt of the second end of bracing piece 200 is in the lateral wall of fixed chamber 301, just the second end width of bracing piece 200 is greater than the width at the middle part of bracing piece 200, like this, can make the second end of bracing piece 200 can fully contact with pre-buried box 300 for connection between them is more inseparable. It should be noted that the first end of the support rod 200 can be connected to the horizontal bar body 100 by using the existing horizontal bar connection method, which is not described redundantly in this embodiment.

Specifically, pre-buried box 300 installs in the subaerial, digs a mounting groove on ground during the installation promptly for pre-buried box 300 is placed in the installation, and after pre-buried box 300 installed, then covers pre-buried box 300 with cement, and cement covers in the outside that is close to the second end of bracing piece 200, makes the second end of bracing piece 200 and pre-buried box 300 be located the below on cement ground.

In this embodiment, since the embedded box 300 is installed under the ground and covered by the cement layer, the embedded box 300 can be stably fixed on the ground, and the embedded box 300 can support the supporting rod 200. Specifically, the fixing portion 210 and the supporting rod 200 are integrally formed, and the width of the fixing portion 210 is greater than that of the supporting rod 200, so the fixing portion 210 can be inserted into the fixing groove 302, and tightly abut against the side wall and the bottom of the fixing groove 302 through the cushion pad 220, so the fixing groove 302 can well limit the fixing portion 210, and the fixing portion 210 is prevented from shaking, in addition, the end surface of the second end of the supporting rod 200 abuts against the bottom of the fixing cavity 301, and the outer side surface of the second end of the supporting rod 200 abuts against the side wall of the fixing cavity 301, so that the inner side surface of the embedded box 300 can support the supporting rod 200, and the displacement of the supporting rod 200 is effectively limited, and further the second end of the supporting rod 200 can be stably fixed in the embedded. In addition, because the width of fixed part 210 is greater than the width of bracing piece 200, and then make the area of fixed part 210 at radial cross section be greater than the area of the radial cross section of bracing piece 200, like this, the lateral wall butt of fixed part 210 and fixed slot 302 can increase the bracing piece 200 at the footpath with the area of contact of pre-buried box 300, that is to say, increased the bracing piece 200 in the horizontal direction with the area of contact of pre-buried box 300, can make the bracing piece 200 receive bigger support on the radial direction, make the bracing piece 200 more firm.

In the above-mentioned embodiment, during the installation, install pre-buried box 300 in the subaerial, support the second end of bracing piece 200 through pre-buried box 300 for bracing piece 200 can be fixed subaerial firmly, in addition, because pre-buried box 300 is installed in the subaerial, the hookup location of effectively having avoided bracing piece 200 and pre-buried box 300 exposes outside, and need not to adopt screw or bolt to be connected bracing piece 200 and pre-buried box 300, can effectively avoid the rainwater to erode and the rust that arouses like this. On the other hand, through setting up blotter 220, can for providing the buffering between bracing piece 200 and the pre-buried box 300, effectively for horizontal bar 10 provides the buffering when receiving the impact of user's motion, and then improve the stability of being connected between bracing piece 200 and the pre-buried box 300, and then make horizontal bar 10 still can fix on ground firmly after long-time the use, effectively improve life.
