[0006] The technical problem to be solved by the utility model can also be realized by the following technical scheme, the pull apart assembly is equipped with connecting sleeve, and the connecting sleeve is equipped with safety pin convenient for pulling apart between the connecting sleeve and the left cross bar and between the connecting sleeve and the right cross bar.
[0007] The technical problem to be solved by the utility model can also be realized by the following technical scheme, the top and the bottom of the left cross bar and the right cross bar are symmetrically provided with movable port for safety pin movement, the safety pin penetrates from the movable port at the top of the left cross bar or the right cross bar to the movable port at the bottom, and the safety pin below the left cross bar or the right cross bar is provided with a nut.
[0008] The technical problem to be solved by the utility model can also be realized by the following technical scheme, the pull apart assembly includes a first ear plate fixed on the left cross bar, a second ear plate fixed on the right cross bar, and a pull apart pin inserted between the first ear plate and the second ear plate.
[0009] Compared with the prior art, the utility model discloses through the left and right symmetry of left horizontal pole and right horizontal pole that the horizontal pole is opened in the middle of horizontal pole, under the connection of hinge, make the horizontal pole and the vehicle impact and do not break and break down, through being equipped with the pull apart subassembly, under normal use for connecting left horizontal pole and right horizontal pole, when being hit, force breaks down, better protection horizontal pole. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is first kind structure diagram of safe anti -collision height limiting rod of the utility model,
[0011] Figure 2 It is second kind structure diagram of safe anti -collision height limiting rod of the utility model.
[0012] In the drawing: 1 - left stand, 2 - hinge, 3 - left horizontal pole, 4 - safety pin, 5 - connecting sleeve, 6 - ground, 7 - right stand, 8 - right horizontal pole, 9 - first ear plate, 10 - second ear plate, 11 - pull apart pin. DETAILED DESCRIPTION
[0013] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.
[0014] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0015] REFERENCE Figure 1 And Figure 2 A safe anti-collision height limiting rod with long service life, comprising a left stand 1 and a right stand 7, the bottom of the left stand 1 and the right stand 7 is fixed on the ground 6, the top of the left stand 1 is provided with a left horizontal pole 3, one end of the left horizontal pole 3 is connected with the left stand 1 through a hinge 2, the top of the right stand 7 is provided with a right horizontal pole 8 which is arranged at the same height as the left horizontal pole 3, one end of the right horizontal pole 8 is connected with the right stand 7 through a hinge 2, the length of the left horizontal pole 3 is equal to the length of the right horizontal pole 8, and a pull apart assembly is arranged between the other end of the left horizontal pole 3 and the other end of the right horizontal pole 8.
[0016] The structure of the pull apart assembly includes but is not limited to the following two kinds,
[0017] The first kind, provided with connecting sleeve 5, connecting sleeve 5 and left horizontal rod 3 between, connecting sleeve 5 and right horizontal rod 8 between are provided with the safety pin 4 of facilitating to pull off, the top and bottom of left horizontal rod 3 and right horizontal rod 8 are symmetrically provided with the movable mouth of safety pin, the safety pin is penetrated from the movable mouth of left horizontal rod or right horizontal rod top to the movable mouth of bottom, the safety pin below left horizontal rod or right horizontal rod is equipped with nut.
[0018] The second kind, including the first ear plate 9 fixed on left horizontal rod 3, the second ear plate 10 fixed on right horizontal rod 8 and the pull-off pin 11 threaded between the first ear plate 9 and the second ear plate 10.
