Abstract
The utility model relates to a top support angle adjuster for a mosquito net support frame, which composed of two screw rods and a sleeve barrel with both ends provided with inner screw threads, wherein, the two screw rods respectively have left hand screw threads and right hand screw threads and are respectively connected with the sleeve barrel with one end provided with left hand inner screw threads and the other end provided with right hand inner screw threads; the two top support angle adjusters are respectively fixedly arranged between the upper parts of back columns on both sides of the back part of a mosquito net support frame and the back part of a side frame of the top support. Simultaneously, the two sleeve barrels are rotated in the same direction and then the size of an elevation angle of the top support corresponding to the horizontal plane can be synchronously adjusted. The utility model has the advantages of convenient adjustment, labor saving, beautiful appearance, etc.
Description
The utility model relates to the mosquito net frame class, the upper frame angle demodulator that particularly a kind of mosquito net frame is used.
Mosquito net employed telescopic square tube support in existing a kind of imperial palace is made up of two square tube rear pillars, square tube upper frame, the flexible draw off gear of mosquito net and connector.Between upper frame side frame rear portion and the corresponding auxiliary angle bar that is packed in the square tube rear pillar, the upper frame angle demodulator is housed, this angle demodulator is made up of upper and lower sleeve pipe and bolt and nut, upper and lower sleeve pipe one end is inserted in bolt two respectively, the last sleeve pipe other end and upper frame side frame rear portion flexibly connect, and the setting of casing other end is dynamically connected with the auxiliary angle ironwork that is packed in the square tube rear pillar.When adjusting the upper frame plane, prop up upper frame, move on the nut with the another hand-screw then and move or move down, put down upper frame, just can obtain the size at the elevation angle with hand to the elevation angle of horizontal plane.This upper frame angle demodulator structure is simple and crude, needs two hands to move together during monolateral adjusting, when both sides are regulated, needs a people constantly to regulate in turn on both sides or needs two people to regulate simultaneously, thereby regulate very trouble, and outward appearance is also very simple and crude, lacks aesthetic feeling.
It is a kind of easy to adjust, laborsaving that the purpose of this utility model is to provide, the upper frame angle demodulator that the mosquito net frame of good looking appearance is used.
The purpose of this utility model is achieved in that the upper frame angle demodulator that a kind of mosquito net frame is used, two side frames that comprise two rear pillars and upper frame, between the side frame rear portion of described rear pillar top and upper frame, the upper frame angle demodulator is housed, this angle demodulator is made up of two screw rods and double headed roller inner thread sleeve, two screw rods are respectively left hand thread, right-handed thread, with a headband levogyrate inner thread, the sleeve of another headband dextrorotation internal thread is connected.Rotational sleeve just can make the protruding or inside contraction simultaneously of connected two screw rods, thereby, regulated the elevation angle size of upper frame to horizontal plane.
Advantage of the present utility model is to regulate very convenient, and is laborsaving, and good looking appearance is generous.
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation that the utility model is used for extendible square tube guide rail mosquito net frame.
By following embodiment the utility model is further elaborated.
Referring to Fig. 1, shown in Figure 2, the upper frame angle demodulator of present embodiment is loaded on the square tube guide rail mosquito net frame that mosquito net can actuate.This upper frame angle demodulator 15 is made up of upper and lower screw rod 1,5 and double headed roller inner thread sleeve 3, and upper and lower screw rod 1,5 is respectively right-handed thread 2, left hand thread 4, is connected with the sleeve 3 of a headband dextrorotation internal thread, another headband levogyrate inner thread.Sleeve 3 appearance annular knurls form with brass car system.When mosquito net frame is installed, with two rear pillars 16, after-frame 14, two band guide rail side frames 13 and before frame 11 be connected and fixed, then two shore frame angle demodulators 15 are separately fixed between the side frame 13 and rear pillar 16 of both sides, mosquito net frame rear, with two hands elevation angle size that rotational sleeve 3 just can the relative horizontal plane of adjusted in concert upper frame in the same way respectively.Regulate very conveniently, effect is also fine.
