Description

Structure improved door locators for poles

The utility model relates to the positioner of door, particularly locator.

At present common door locators for poles (as shown in Figure 1, 2) A is the appropriate location that is embedded in the floor, and its primary structure comprises: the sleeve of an external screw thread B1, a spring C and a roof pressure piece D.This locator A is embedded under the floor of appropriate location, iron gate limit, by being usually located at the suitably iron gate in area of building, for example the iron gate of the import and export of the import and export of mansion or other large areas is normally detained by day and is opened, and be to close in night, when iron gate cuts out, iron gate must have a location device, usually the backstay E that will be attached to iron gate side lower end by operating personnel shuttles back and forth to press to give as security and contracts after roof pressure piece D makes roof pressure piece D, backstay E stretches among the locator A, again with the button structure (not shown) of backstay E clip on iron gate then iron gate effectively located.When iron gate was opened, operating personnel were pulled upwardly backstay E, made backstay E break away from locator A, upwards withstood openend because the effect roof pressure piece D of spring C restores to the original state, yet this locator has following defective after permanent the use:

1, when backstay E does not act on the locator A, because people or thing run over that locator A goes up or when sweeping ground, article such as foreign material are packed on the roof pressure piece D, cause roof pressure piece D to sink, the backstay E of iron gate inserts among the locator A as stone among Fig. 2, roof pressure piece D can't be risen, so can't articulate fixing with locator A.

2, this locator A also can be contained in (not shown) in the corresponding aperture of doorframe key nose bar, door can comprise automatic door or other has the key door of locating with nose bar, when door must open or close often, has a kind of situation to take place usually, that is: this must be in situation of unlatching, for example still at the StoreFront of business, by (may think and close) under the outer situation of people's will door is locked admittedly, promptly the nose bar of key (the quite backstay E of iron gate) stretches among the locator A, cause door to open, personnel can't pass in and out.Tracing it to its cause is that the roof pressure piece D of locator A is stressed to intrinsic displacement, and the nose bar that can't select to maintain static to prevent key stretches in the locator unexpectedly.

The purpose of this utility model is to provide a kind of structure improved door locators for poles that overcomes above-mentioned defective, is not packed into locator to improve the application life of locator by foreign material when the performance locator does not use.

Another purpose of the present utility model is when being used for the nose bar jack locator of door key, has and can select to prevent that nose bar from entering the effect in the locator holes.

The structure improved door of the utility model locators for poles, by one externally threaded outer sleeve is arranged, its bottom can affixed base plate, be provided with the fixed head of screw in the middle of one, plate face two sides are respectively equipped with perforation, the external screw thread of outer sleeve can be screwed in this screw, and a spring is to be inserted in the sleeve pipe, and one is positioned at that socket one roof pressure piece is formed by combining on the spring.The tube wall that it is characterized in that intermediate casing is provided with straight trough longitudinally, the straight trough top forms a bigger breach, cause and form upper and lower two gulde edges, and the side of roof pressure piece is provided with a small convex pillar and can selects to be positioned on the upper and lower gulde edge, plane, roof pressure piece top is provided with horizontal groove.

The utility model has the advantages that:

1, when using with iron gate backstay location, the top pressing board that is embedded in iron gate appropriate location underfloor door locators for poles is provided with small convex pillar, as long as turn roof pressure piece groove gets final product lock in place, crushed stone, foreign material can not be packed into locator sinks the roof pressure piece.

2, when the door locators for poles was packed on the doorframe, particularly suitable included automatic door or has the key door use of nose bar location, as long as turn roof pressure piece groove can reach location or mobile status.

The utility model is described in further detail below in conjunction with accompanying drawing.

Structure improved locator (seeing also Fig. 3,4) comprises:

One has external screw thread 12 and is the outer sleeve 10 of hollow, and its bottom can affixed base plate 14;

Be provided with the fixed head 50 of screw 52 in the middle of one, its plate face two sides are respectively equipped with

perforation

53,54, and the external screw thread 12 of outer sleeve 10 can be screwed in the screw 52;

One intermediate casing 20 is close allocating in the outer sleeve 10;

One spring 30 is to be inserted in the sleeve pipe 20;

One is positioned at socket one roof pressure piece 40 on the spring 30.The tube wall that it is characterized in that intermediate sleeve 20 is provided with straight trough 22 longitudinally, straight trough 22 tops form a bigger breach 24, the side that causes upper and lower two gulde edges 241,221 of formation and roof pressure piece 40 is provided with small convex pillar 42 and can selects to be positioned on the upper and lower gulde edge 241,221, and the plane, top of roof pressure piece 40 is provided with horizontal groove 45.

(see also Fig. 4 when the door locators for poles of improvement tangerine structure and the backstay location of iron gate, 5), the door locators for poles is embedded under the appropriate location of floor F, outer sleeve 10 is become one with the concrete embedding, pass the perforation 53 of fixed head 50 again with

screw

58,54 backs are fixed with floor F, when the user will be positioned at the backstay 82 of iron gate 80 in the intermediate sleeve 20, as long as go into turn in the groove 45 with a coin 60 or with the bottle opener correspondence, small convex pillar 42 on the roof pressure piece 40 can embed in the straight trough 22 and (see also Fig. 6), with backstay 82 roof pressure roof pressure pieces 40, then spring 30 compressions, roof pressure piece 40 sinks, again with backstay 82 clips (not shown) on iron gate 80, backstay 82 is positioned in the intermediate sleeve 20, can reach iron gate cuts out and locating effect.

After iron gate 80 is opened, behind user's pull-up backstay 82, go into turn again in the groove 45 with coin 60 or with the bottle opener correspondence again, roof pressure piece 40 is by spring 30 jack-up, and the small convex pillar 42 on the roof pressure piece 40 just is positioned at after being rotated and (sees also Fig. 7) on the gulde edge 241, so roof pressure piece 40 can't be to bottom offset, therefore, after iron gate 80 is opened, do not have the foreign material spreading on roof pressure piece 40 yet, roof pressure piece 40 is descended and enter in the intermediate sleeve 20.

Whether admittedly when structure improved door locators for poles is loaded on the door lock (seeing also shown in Figure 8), the door locators for poles is fixedly connected on the doorframe 90, and the nose bar 94 of door lock 92 can be selected to enter in the intermediate sleeve 20, reach door lock 92 purpose of lock.After door is opened, especially refer to automatic door, in the current process of people, cause people to pass in and out for preventing that door lock from not locked unexpectedly admittedly, as long as coin 60 correspondences are gone into turn in the groove 45, the small convex pillar 42 on the roof pressure piece 40 just is positioned on the gulde edge 241, makes roof pressure piece 40 be positioning states, even cause the nose bar 94 pleasant solid locks of door lock 92 to move, also can't stretch in the locator.In the time will locking admittedly, as long as the user is turn groove 45, and the small convex pillar 42 on the roof pressure piece 40 can displacement in straight trough 22, and nose bar 94 can be locked admittedly easily and stretches in the locators for poles.
