The fixing base comprises an installation groove, a blocking head is arranged at one end of the installation groove, a threaded hole is formed in the blocking head, the adjusting screw rod penetrates through the threaded hole, the installation wheel device is arranged in the installation groove, the rotary shaft is connected with the installation groove and the installation wheel device, the section of one end of the adjusting screw rod is a polished rod section, the diameter of the polished rod section is smaller than the diameter of the screw rod section of the adjusting screw rod, the polished rod section is sleeved with one end of the damping spring, the other end of the damping spring abuts against the installation wheel device, and the abutting position between the damping spring and the installation wheel device is located below the rotary shaft. The lower positioning wheel is easy to install, and the height of the lower positioning wheel can be adjusted after the lower positioning wheel is installed without disassembly. Due to the fact that the damping spring is arranged, the door can be opened and closed more smoothly, and the noise is lower. The lower positioning wheel can be suitable for door leaves with various widths.
Description
Technical field
The utility model relates to door and window assembly field, particularly a kind of lower locating wheel.
Background technology
Lower locating wheel now is that fixed head adds single-wheel device formation, and lower locating wheel has following shortcoming when door, window etc. is installed and used: 1, the wheel size must change with the width of door leaf, or the door leaf width is affected by the locating wheel size.Can cause door leaf to rock greatly if 2 wheels are too small, wheel and door leaf produce hard friction if wheel is excessive, affect smooth degree and noise is arranged.3, size specification is fixed, can not regulate height after the installation, and in order to make door or window result of use good, need to determine a suitable whole height, in order to determine that whole height often needs to regulate by the installation site of lower locating wheel, refitting was very inconvenient if improper needs are dismantled when existing door or window were installed.
The utility model content
The purpose of this utility model provides a kind of lower locating wheel.
According to an aspect of the present utility model, a kind of lower locating wheel is provided, comprise holder, rotating shaft, the mounting wheel device, damping spring and adjusting screw(rod), holder comprises mounting groove, mounting groove one end is provided with stopper and the stopper place is provided with screwed hole, adjusting screw(rod) passes screwed hole, the mounting wheel device is located in the mounting groove, rotating shaft connection groove and mounting wheel device, one section of adjusting screw(rod) termination is the polished rod section, polished rod section diameter is less than the spiro rod section diameter of adjusting screw(rod), damping spring one end is set on the polished rod section, the damping spring other end is against on the mounting wheel device, damping spring and the mounting wheel device place of offseting are positioned at the rotating shaft below, and the mounting wheel device forms lever under the effect of damping spring and adjusting screw(rod), need not dismantle and just can play the effect of regulating height, damping spring can play the function that reduces to vibrate, and the door leaf that lower locating wheel can corresponding plurality of specifications width and good stability are not prone to and rock or the problem such as friction.
In some embodiments, the mounting wheel device comprises movable part, roller, roller shaft, axis hole and supports point, roller shaft passes roller and connects movable part, supporting point is corresponding damping spring place on the movable part, and the mounting wheel device plays the purpose that reduces object friction of generation when mobile that lower locating wheel is installed.
In some embodiments, the middle part of roller outer annular surface is provided with U-lag, and U-lag can play locating effect, the convenient installation, and also easier track with plurality of specifications is corresponding.
In some embodiments, the external diameter of damping spring is less than the external diameter of the spiro rod section of adjusting screw(rod), and adjusting screw(rod) can push damping spring and make the stressed work of damping spring like this.
In some embodiments, holder is provided with installing hole, and installing hole can make things convenient for holder to be connected on other objects.
Description of drawings
Fig. 1 is the structural representation of the lower locating wheel of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of lower locating wheel, comprise holder 1, rotating shaft 2, mounting wheel device 3, damping spring 4 and adjusting screw(rod) 5, holder 1 comprises mounting groove 9, mounting groove 9 one ends are provided with stopper 10 and stopper 10 places are provided with screwed hole, adjusting screw(rod) 5 passes screwed hole, mounting wheel device 3 is embedded in the mounting groove 9, rotating shaft 2 connection grooves 9 and mounting wheel device 3, one section of adjusting screw(rod) 5 termination are the polished rod section, polished rod section diameter is less than the spiro rod section diameter of adjusting screw(rod) 5, damping spring 4 one ends are set on the polished rod section, and damping spring 4 other ends are against on the mounting wheel device 3, and damping spring 4 is positioned at rotating shaft 2 belows with mounting wheel device 3 places of offseting, the external diameter of damping spring 4 is less than the external diameter of the spiro rod section of adjusting screw(rod) 5, and adjusting screw(rod) 5 can push damping spring 4 and make damping spring 4 stressed work like this.Mounting wheel device 3 comprises movable part 6, roller 7, roller shaft, axis hole and supports point, roller shaft passes roller 7 and connects movable part 6, supporting point is corresponding damping spring 4 places on the movable part 6, and mounting wheel device 3 plays the purpose that reduces object friction of generation when mobile that lower locating wheel is installed.
Holder 1 is provided with installing hole 8, and installing hole 8 can make things convenient for holder 1 to be connected on other objects.
Lower locating wheel is provided with the below that installing hole 8 is fixedly connected on door or window by holder 1, the middle part of roller outer annular surface is provided with U-lag 11, the roller 7 of mounting wheel device 3 is on the protruding track of door leaf or sash below, the effect that roller 7 plays the location and rolls, such structure is convenient the installation not only, and roller 7 can be fit to the protruding track of multiple width, general so can the appearance causes door leaf to rock greatly because wheel is too small, or the excessive then wheel of wheel and door leaf generation hard friction, affect smooth degree and the situation of noise is arranged, the situation that causes regulating locating wheel because of the change width of door leaf or sash can be avoided in roller 7 automatic position of adjustment doors or window on the protruding track.
Lower locating wheel described in the utility model needn't be considered the door leaf width, and size is all applicable, and wheel and door leaf bottom close contact rock minimum, install simple and easyly, just need not dismantle after the installation and can regulate, debugging is convenient, wheel has shock-proof spring, and more smooth and easy during switching door, noise is less.
