Accompanying drawing explanation
accompanying drawing 1 is the main TV structure schematic diagram of most preferred embodiment of the present invention.
accompanying drawing 2 is the plan structure schematic diagram of accompanying drawing 1.
accompanying drawing 3 is accompanying drawing 1 looks up structural representation.
coding in accompanying drawing is respectively: 1 is firm banking, and 2 is guide spiro rod, and 3 is hand holding lock lock mouth frame, and 4 is fore shaft, and 5 is adjustable limiting nut, and 6 pull groove for hand, and 7 is spacing fixture block, and 8 is screw rod righting seat, and 9 is base installing hole, and 10 is drag reduction nut ring platform.
The specific embodiment
the present invention is not subject to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
in the present invention, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the invention will be further described:
as shown in Figure 1, this T shape handle is locked adjustable snap close and is comprised firm banking 1, guide spiro rod 2, hand holding lock lock mouth frame 3 and adjustable limiting nut 5; On firm banking 1, interval is provided with two vertical guide spiro rods 2, and the hand holding lock lock mouth frame 3 of energy up-down adjustment is installed on guide spiro rod 2, is useful on the fore shaft 4 of the handle hook limitation locking of T shape handle on hand holding lock lock mouth frame 3; On the guide spiro rod 2 of the top and bottom of hand holding lock lock mouth frame 3, by screw thread, be installed with adjustable limiting nut 5 respectively.The present invention is arranged on the doorframe and window frame corresponding with T shape handle; Bar, when closing, can screw in fore shaft 4 its handle hook by manual rotation T shape handle, makes between bar and doorframe and window frame spacingly, realizes door and window sealing locking; At this, cross Cheng Qian, user can pass through up-down adjustment hand holding lock lock mouth frame 3, when making to lock between bar and doorframe and window frame, leaves certain ventilation voids, thereby plays the effect that regulates interior temperature; Bar can not held by wind, and reliability is high, safe; For guaranteeing the wind pressure resistant strength of hand holding lock lock mouth frame 3, the height of hand holding lock lock mouth frame 3 is more than or equal to 21 millimeters.
can according to actual needs, above-mentioned T shape handle be locked to adjustable snap close and make further optimization and/or improvements:
as shown in Figure 1, on firm banking 1, be interval with two screw rod installing holes that communicate up and down, in the lower end of guide spiro rod 2, be fixed with the corresponding columniform screw rod righting seat 8 of screw rod installing hole internal diameter, guide spiro rod 2 is radially installed in screw rod installing hole by screw rod righting seat 8.Guide spiro rod 2 and firm banking 1 are respectively individual components and the form by assembling is installed together, and when guide spiro rod 2 or firm banking 1 are damaged, can again use by changing these damage parts, reduces maintenance cost of the present invention; 8 pairs of screw rod righting seats are arranged on the effect that guide spiro rod 2 in screw rod installing hole plays radially spacing and righting.
as shown in accompanying drawing 1,3, bottom the outer ring surface of each screw rod righting seat 8, circle distribution has at least two spacing fixture blocks 7 that are centrosymmetric respectively, on the screw rod installing hole inner edge of firm banking 1 bottom, be distributed with the radially draw-in groove corresponding with spacing fixture block 7, spacing fixture block 7 is arranged on radially in draw-in groove.Spacing fixture block 7 is arranged on radially in draw-in groove, makes guide spiro rod 2 rotary stoppers, is convenient to adjustable limiting nut 5 to carry out screw thread rotation adjusting.
as shown in Figure 1, on the firm banking 1 of the left and right sides of two guide spiro rods 2, there is respectively base installing hole 9; Or/and, on the firm banking 1 between two guide spiro rods 2, be laterally distributed with at least one base installing hole 9.
as required, base installing hole is Y shape counter sink wide at the top and narrow at the bottom.
as shown in Figure 1, in the upper end of firm banking 1, be the low ramp shapes in high both sides, middle part; Screw rod installing hole lateral separation is distributed in firm banking 1 middle part.
as shown in Figure 1, the upper end of adjustable limiting nut 5 is or/and lower end is provided with the drag reduction nut ring platform 10 that end face is less than adjustable limiting nut 5.Because the face area of drag reduction nut ring platform 10 is little, can reduce adjustable limiting nut 5 and the contact area contacting between end face, reduce frictional resistance, conveniently manually exchanging stop nut 5 carries out degree of tightness adjusting.
as shown in Figure 1, adjustable limiting nut 5 is round nut, and in the outer rim of adjustable limiting nut 5, circle distribution has the hand of at least four circular arcs to pull groove 6, and the adjustable limiting nut 5 between adjacent forms nut spanners.With finger, put into hand and pull groove 6 and fasten nut spanner, the rotation application of force, adjustable limiting nut 5 can be realized and screws on or back off with hand-screw, easy to adjust, easy to use.
as shown in Figure 1, fore shaft 4 comprises hole, the narrow footpath section of hole, wide footpath section, middle part reducing transitional pore section and the right part of left part; Hole, narrow footpath section is corresponding with the thickness of the handle hook of T shape handle.Because the hole width of hole, the wide footpath section of left part is larger, the handle hook that can be convenient to T shape handle screws in; Screw-in by reducing transitional pore section to hole, narrow footpath section, the thickness of the handle hook of the Kong Kuanyu T shape handle of hole, narrow footpath section is corresponding, reduces transverse shifting gap, while preventing from blowing in locking, because transverse shifting gap shakes bar greatly, improve the application life of bar.
above technical characterictic has formed most preferred embodiment of the present invention, and it has stronger compliance and best implementation result, can increase and decrease according to actual needs non-essential technical characterictic, meets the demand of different situations.
