Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Referring to figs. 1 to shown in Fig. 5, a kind of reinforcement type doorframe horizontal bar, including telescopic rod 1, support holder assembly.
Telescopic rod 1 includes adjusting section 11 and two extended segments 12, and two extended segments 12, which are respectively arranged on, adjusts 11 both ends of section, and two
A extended segment 12 is connect by positive and negative screw thread with section 11 is adjusted respectively, and adjusting section 11 by rotation can make two extended segments 12 same
Shi Shenchang is shunk simultaneously.
Supporting holder assembly includes the first support base 2, the second support base 3, supporting sleeve 4, support rod 5.
First support base 2 and the second support base 3 include top pressure face, two side walls face, and top pressure face is located at the outer of support base
Side, top pressure face are equipped with elastic cushion 6, and top pressure face is plane and offers several mounting holes thereon, and 6 medial surface of elastic cushion offers
The mounting blocks 61 of several protrusions, elastic cushion 6 are packed into mounting hole by mounting blocks 61 and are bonded installation, 61 end of mounting blocks with top pressure face
Equipped with retaining ring 62, mounting blocks 61 are in clamping connection after being inserted into mounting hole by retaining ring 62；The side wall surface of first support base 2 is equipped with
Coaxially arranged through hole, 3 side wall surface of the second support base offer coaxially arranged through hole.
The end sleeve of the extended segment 12 of telescopic rod 1 is set in supporting sleeve 4, and the outer diameter of extended segment 12 is equal to supporting sleeve
4 internal diameter, the tube wall of supporting sleeve 4 are set there are two coaxial through hole, and the extended segment 12 of telescopic rod 1 sets that there are two coaxial to pass through
Perforation, the through hole of 2 side wall surface of the first support base, the through hole on 4 tube wall of supporting sleeve, 1 extended segment 12 of telescopic rod are run through
Hole, which is coaxially disposed and passes through bolt, passes through connection, so that supporting sleeve 4 and the first support base 2 realize rotation connection, and limits
Relative rotation between the extended segment 12 of supporting sleeve 4 and telescopic rod 1.
5 one end of support rod is fixedly connected by welding with 4 bottom of supporting sleeve, and the other end and the second support base 3 are rotatable
Connection；The axis of support rod 5 and the axis of supporting sleeve 4 are generally aligned in the same plane, the axis of support rod 5 and the axis of supporting sleeve 4
Line is in 10 ° of -60 ° of angles settings, preferably 25 °, 30 °, 35 ° of settings；One end side wall that support rod 5 is connect with the second support base 3 opens up
Have a through hole, support rod 5,3 side wall surface of the second support base each through hole be coaxially disposed and pass through bolt and pass through connection, realize branch
Strut 5 is rotatably connected with the second support base 3.
This kind of doorframe horizontal bar working principle is as follows: the doorframe horizontal bar be horizontally placed on the inside of doorframe, the axis of support rod 5,
