Abstract

The utility model relates to a positioning device for fixing a moving body at a certain position. The utility model adopts a biasing tongue and a narrow groove which are two position automatic changing and locking structures and is composed of a movable body (1) and a static body (2). The movable body (1) is composed of a fixed tongue wheel (11), a movable tongue wheel (12), a spring (13), and accessories, the static body (2) is composed of a cylindrical cavity body (21) and an elastic body (22), and the movable body (1) and the static body (2) are respectively installed on the moving body and at a set fixed position. The utility model with the advantages of large positioning force and small force for the disengagement from position is suitable for being used as a door holder and can also be used as a stopping or locking device for windows and cabinets, as a door lock for refrigerators, and as a built-in lock for drawers.

Description

Autonavigator

The utility model autonavigator relates to the positioning devices that mobile object is fixed in a certain position, belongs to mechanical locking.

Existing locator, having that for example the pivoted door holder is common is magnetic-type, soft or hard ball-and-spigot, friction-type etc. are several, and their common drawback is: the power of fixed door and to break away from fixed power the same big, promptly, desire to make the power of fixed door very big, the power of closing the door so is big too, and it is very inconvenient to close the door; Otherwise, to close the door conveniently for making, the power of fixed door can not be very big, and door tends to be blown accident by strong wind and closes the door and send loud noise so, and fixed door effect is bad.This is the requirement of a pair of contradiction each other.

The purpose of this utility model is exactly in order to solve this a pair of contradiction, it is very big to reach both feasible strength of locating, and makes that again the power that breaks away from the location is very little, easy to use, produce simple in structure, lower-cost locator, for example Ding Men and the door holder of closing the door and all feeling quite pleased.

The purpose of this utility model is to realize like this, the a pair of positioning devices that employing is made of kinetoplast and quiet body two parts, kinetoplast, quiet body are installed in mobile object respectively and intend on the fixing position, this positioning devices constitutes one group of two position and changes locking mechanism automatically, mobile object is pinned by mechanism when operating for the first time, can't withdraw from; Afterwards, when operating for the second time, mobile object is taken off lock automatically by mechanism.

The concrete structure that two positions are changed locking mechanism automatically is a lot, and one of them embodiment is called biasing tongue-narrow groove two positions exactly and changes latch-up structure automatically.The positioning devices of this kind structure is made of kinetoplast [1] and quiet body [2] two parts, and the two is installed in mobile object respectively and intends on the fixing position.

Kinetoplast [1] is by fixing tongue wheel [11], movable tongue wheel [12] and kinetoplast spring [13] and annex are formed, fixedly the base of tongue wheel [11] is installed on the mobile object, movable tongue wheel [12] and kinetoplast spring [13] are enclosed within fixedly, and the axial region of tongue wheel [11] also can sway and move up and down, but can not break away from fixedly tongue wheel [11], fixedly the circumference cylinder of tongue wheel [11] and movable tongue wheel [12] has X five equilibrium tongue (this routine X=4), their contact end face respectively has 2X five equilibrium tooth, and fixedly tongue wheel [11] and movable tongue wheel [22] tongue has certain biasing with respect to the position of their tooth.Be subjected to the compressing of kinetoplast spring [13], fixedly tongue wheel [11] and movable tongue are taken turns [22] and are meshed by tooth and constitute the biasing tongue.

Quiet body [2] is made up of the cylindrical cavity [21] and the elastic body [22] of the hollow of a band base, be installed on the position of intending fixing by base, 2X groove arranged on the internal chamber wall of cavity [21], wherein X open channel and X undercut arranged spaced, the opening of open channel is at the end face of cavity [21] and certain fillet is arranged, undercut is at the end face imperforation, open channel is over against the tongue of fixing tongue wheel [11] and slightly wideer than tongue, so that tongue enters quiet body [2] smoothly, but than kinetoplast [1] when not being subjected to external force fixedly total groove width of tongue and movable tongue be narrow, thereby constitute narrow groove.Elastic body [22] can be spring.

Below in conjunction with drawings and Examples the utility model autonavigator is described further.

Fig. 1 is the scantling plan of the utility model autonavigator.

Fig. 2 is kinetoplast in the autonavigator shown in Figure 1 [a 1] parts drawing.

Fig. 3 is quiet body [a 2] structure chart in the autonavigator shown in Figure 1.

Fig. 4 is tongue, the tooth on kinetoplast in the autonavigator shown in Figure 1 [1] and the quiet body [2], the plane outspread drawing of groove.

Among the figure, 1---kinetoplast, 2---quiet body, 11---fixedly tongue is taken turns, and 12---movable tongue wheel, 13---the kinetoplast spring, 21---cylindrical cavity, 22---elastic body.

In Fig. 1, because the effect of kinetoplast spring [13], fixedly tongue wheel [11] and movable tongue wheel [12] on the kinetoplast [1] mesh by tooth, but the tooth of at this time movable tongue wheel [12] be with quiet body [2] on open channel the biasing of certain distance is arranged, when kinetoplast [1] has just entered quiet body [2], the effect that the lower inclined plane of movable tongue wheel [12] and quiet body [2] are gone up the angle, garden of open channel mouth makes [12] horizontal deflection of movable tongue wheel, just can make kinetoplast [1] enter the open channel of quiet body [2] together, after movable tongue wheel [12] is all walked out the lower port of open channel, kinetoplast spring [13] resets movable tongue wheel [12], movable tongue wheel [12] is subjected to the undercut that effect at angle enters quiet body [2] on it, kinetoplast [1] is return by the effect of elastic body [22] also, and pinned by quiet body [2], any big pulling force that is lower than fracture strength all can't make kinetoplast [1] withdraw from from quiet body [2].

When promoting kinetoplast [1] once more, based on the operating principle identical with last time, movable tongue wheel [12] is subjected to the effect at angle on it to enter another open channel of quiet body [2], is subjected to the effect of elastic body [22], and kinetoplast [1] can freely withdraw from from quiet body [2].

Dependence is changed locking mechanism automatically by this two positions that kinetoplast [1] and quiet body [2] constitute, and positioning devices of the present utility model has been realized lock, put alternate functions.

In use, as needs, the installation site of kinetoplast and quiet body can exchange, and promptly kinetoplast is installed in and intends fixing position, and quiet body is installed on the mobile object.

The utility model compared with prior art has following advantage:

1, as long as just can make mobile object automatically be locked to desired location with very little thrust, big pulling force also can't take off again Lock, bed knife is big;

2, as long as just can make the motive objects that is locked to desired location take off lock with very little thrust, mobile object can be again extensive Multiple freely-movable state, easy to use;

3, with very simple method solved big bed knife and little recovery locomotivity this to contradiction;

4, select suitable spring force, device also has the effect of built-in lock;

5, when locking at every turn and taking off lock, all can hear " click rattles away " the sound, play good indicative function.

The utlity model has multiple use, for example:

Kinetoplast is by being loaded on the pivoted door and window, and quiet body is installed on the wall, plays the purposes of automatic door holder or window fixing device.Kinetoplast and quiet body are respectively by being loaded on the drawer and in the cabinet, playing the effect of built-in lock.In addition, this locator is as the door lock of refrigerator doors, and the power of then closing the door is bigger, and it is little to smoke power than existing magnetic door when opening the door, and each all sound snap of open and close door shows, uses more reliable convenience.
