Abstract

An embodiment of the utility model discloses an inserted pin, which is designed to reduce the occupying outer space when being connected with mechanical parts. The inserted pin comprises an inserted pin body which is provided with screen. The screen which is used to limit the inserted pin body is disposed on the top of the inserted pin body. The inserted pin is applicable to the connection between different parts.

Description

A kind of latch

Technical field

The utility model relates to a kind of latch, relates in particular to the screens section of latch.

Background technique

Usually need two mechanical parts are linked together at mechanical field.Referring to shown in Figure 1, wherein a kind of Placement is to connect by latch 1, namely first offers the hole at each parts, and the hole on two parts is corresponding, with getting final product in the hole on latch 1 insertion described two mechanical parts 2 and 3.In order to prevent in use deviating from the hole of described latch 1 on described two mechanical parts, stretch out in the hole on two mechanical parts the lower end of latch 1, lower end at latch 1 is provided with pin hole, utilizes bayonet lock 4 to insert these pin holes to realize spacing to latch.

In realizing process of the present utility model, model utility people finds to stretch out in the hole of lower end on two mechanical parts of latch, although be convenient to offer pin hole and utilize bayonet lock to insert this pin hole to realize spacing to latch, but, stretch out in the hole on two mechanical parts the lower end of latch, has taken more space outerpace.，

The model utility content

The utility model provides a kind of latch, and the space outerpace that takies when connecting mechanical part is less.

For achieving the above object, embodiment of the present utility model adopts following technological scheme:

A kind of latch comprises: latch body, be provided with for latch body being carried out spacing screens section in latch body, and described screens section is located at the upper end portion of described latch body.

Alternatively, described screens section is the draw-in groove that is opened on the described latch body.

Alternatively, described screens section is the hole that is opened on the described latch body.

Preferably, described latch also comprises bayonet lock, and described bayonet lock matches with described screens section.

Preferably, described bayonet lock is the U-shaped bayonet lock.

The latch that the utility model provides, owing to be used for latch body is carried out the upper end portion that spacing screens section is located at latch body, like this when connecting mechanical part, the underpart of latch can be embedded in the hinge last of mechanical part and not stretch out, the underpart of latch is the outer space outerpace of occupying volume no longer, that is the space outerpace that this latch takies when connecting mechanical part is less.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment

Be described in detail below in conjunction with the embodiment of accompanying drawing to the utility model latch.

Should be clear and definite, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiments that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.

To shown in Figure 5, the embodiment of the utility model latch 5 comprises referring to Fig. 2: latch body 51, be provided with for the screens section 52 spacing to latch body in latch body, and described screens section is located at the upper end portion of described latch body.In the utility model, the underpart of latch body refers at first to insert an end of the attachment hole of connected element, and an end that does not insert the attachment hole of connected element is the upper end portion.

Owing to be used for latch body is carried out the upper end portion that spacing screens section is located at latch body, like this when connecting mechanical part, the underpart of latch can be embedded in the hinge last of mechanical part and not stretch out, the underpart of latch is the outer space outerpace of occupying volume no longer, that is the space outerpace that this latch takies when connecting mechanical part is less.

In aforementioned embodiments, described screens section 52 is for being opened in draw-in groove or the hole on the described latch body, and the screens section shown in the figure is the ring draw-in groove, and it is ring that certain described draw-in groove is not limited to, and also can be other forms of draw-in groove.

In order to prevent that latch 5 from deviating from from attachment hole, described latch 5 also comprises bayonet lock 6, and described bayonet lock 6 matches with described screens section 52, to realize spacing to latch body.

Preferably, described bayonet lock 6 is the U-shaped bayonet lock.When the screens section on the described latch body was the hole, described bayonet lock 6 was correspondingly for inserting the pivot pin in the described hole.

Embodiment:

Referring to Figure 6 and Figure 7, correspondence offers through hole on two

mechanical parts

2 and 3, in described through hole, be equipped with latch 5, upper end portion at the body of described latch 5 is provided with for the ring draw-in groove 52 spacing to latch body, in described draw-in groove 52, be arranged with U-shaped bayonet lock 6, this U-shaped bayonet lock 6 inserts and inserts again behind the described draw-in groove 52 in the positioning plate 7 that is fixed on the described mechanical part 2 and be fixed, thus so that the described latch 5 that inserts in the attachment hole of two

mechanical parts

2 and 3 can not automatically deviate from.The underpart of the body of described latch 5 is hidden in the attachment hole of mechanical part 3, do not stretch out and exposed externally, thus so that the underpart of latch 5 does not need the outer space outerpace of occupying volume.

The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
