Description

Door opening pulley assembly Technical Field The utility model belongs to the field of doors, in particular to the field of pulleys for opening doors. Background The inventor's door occasionally fails to lock, appears to be closed, actually is virtually hidden, which makes the inventor very unsecure, and the inventor thinks that there is a pull rope to pull the door all the time, if the door is not locked, the door is opened, not in a hidden state, so that the inventor finds that the door is not locked, and a simpler method is to pull the door all the time by using an elastic pull rope, but has a problem that the elastic rope is always pulled, if being a rubber rope, is easy to age, if being a spring, because personnel are injured due to possible falling. The inventors contemplate that the above problems can be solved simultaneously by having a non-rubber rope that is pulled all the way through the pulley. But is limited to space arrangements and rotation of the pulley during opening of the pull door can cause the pull cord to disengage from the pulley groove, thus requiring a mating pulley assembly. The inventors have found a plurality of netpin platforms, none of which have been found to be on sale. Disclosure of utility model In order to overcome the defects of the prior art, the utility model provides a door opening pulley assembly, which comprises a pulley, a horizontal bracket for installing a pulley shaft and a vertical bracket vertical to the horizontal bracket, wherein the vertical bracket is vertical to the horizontal bracket, one side surface of the vertical bracket is fixedly connected with the horizontal bracket, The other side surface of the vertical bracket is fixedly connected with an internal screw cap, the axis of the internal screw cap is in the horizontal direction, A horizontal rod is also arranged, one end of the horizontal rod is provided with a thread which is used for adapting to the internal thread nut, the other end of the horizontal rod is provided with a vertical rotating shaft in the vertical direction, The vertical rotating shaft is fixedly connected with the middle part of the horizontal rod, and is vertical to the horizontal rod, The wall surface is also provided with a vertical plate which is used for being fixed on the wall surface, the vertical plate is fixedly connected with an upper sleeve and a lower sleeve, the lower end of the upper sleeve and the upper end of the lower sleeve are provided with a space, The upper part of the vertical rotating shaft stretches into the upper sleeve, the lower part of the vertical rotating shaft stretches into the lower sleeve, and the upper sleeve and the lower sleeve can restrict the vertical rotating shaft to rotate only on the vertical axis. Further, still include the horizontal plate, the horizontal plate sets up in lower telescopic below, horizontal plate and perpendicular version fixed connection, and the horizontal plate is equipped with the screw hole, has the jack-up screw in screw hole that suits with the screw hole, and the top of jack-up screw is the pointed end to the bottom of vertical pivot is supported to this pointed end. Further, the pulley is a V-shaped pulley. The utility model can change the direction of the axis of the pulley, so that the stay rope crossing the pulley is always attached to the pulley groove and cannot fall off. Drawings Fig. 1 is a schematic diagram of the structure of the present utility model. In the drawing, a pulley 1, a pulley shaft 2, a horizontal bracket 3, a vertical bracket 4, an internal screw nut 5, a horizontal rod 6, an upper sleeve 7, a lower sleeve 8, a vertical rotating shaft 9, a vertical plate 10, a horizontal plate 11, a threaded hole 12 and a jacking screw 13.
