Description

A kind of heat shield connection structure

Technical field

The utility model relates to a kind of heat shield connection structures, the assembly connection especially between flexible and special-shaped heat shield When, connection member quantity can be effectively reduced, simplifies connection type, has many advantages, such as that assembling structure is simple, securely durable company Binding structure belongs to Standard technical field.

Background technique

Existing conventional heat shields connection is most to arrange a fairly large number of connection member using in heat shield surface, passes through The assembly connection realized between different heat shields, aforementioned company are mutually tightened between wire tensioning connection member or structural member It is cumbersome in heat shield connection, disassembly, maintenance to connect structure type, the time is tediously long, and there is damage in connection member The risk of heat shield.

Summary of the invention

The purpose of this utility model is: a kind of heat shield connection structure is provided, structurally reasonable, connection member quantity is few, It is easy to operate.

To achieve the goals above, the utility model uses following technical scheme:

A kind of heat shield connection structure, including locking key, lock pin and guide base；

The guide base is fixedly connected on heat shield body surface comprising a bottom being connected with heat-insulated cover body Face is provided with hole on bottom surface, a pair of of guide groove is additionally provided on bottom surface；

The lock pin include one be located at its surface annular groove, lock pin be placed in the hole of guide base bottom surface and with it is heat-insulated Cover body is connected；

The locking key includes a pair of deformable bifurcation structure, and the width of bifurcation structure is less than the width of guide groove, bifurcated Structure front end has a head, and the width on head is greater than the width of guide groove, the bending of bifurcation structure rear end, bending section and bifurcation structure Between have an angle, the bifurcation structure is matched with guide groove so that locking key along guide groove slide.Bifurcation structure also is understood as Bayonet arrangement, it can it opens or shrinks along guiding slot width direction in the slip plane of guide groove building, when contraction, bifurcated Structure is slided by guide groove, realize when opening bifurcation structure and detent surface annular groove locking limit (when opening, bifurcated knot Limit in the stuck lock pin annular groove of structure head, after head is opened, width is greater than guiding groove width, avoids rollback).

Preferably, the guide base is welded on heat shield body surface.

Preferably, there is a blind hole in the lock pin lower end surface, and lock pin is riveted by blind hole and heat-insulated cover body.

Preferably, the bifurcation structure of the locking key is in U-shape, and U-shaped rear end bending and with two side (examples in a certain angle As vertically), respectively there is an abducent head in two sides front end.

Preferably, two guide grooves of the guide base are parallel to each other, and section is in [font.

Compared with prior art, the structure of the utility model changes previous heat shield connection structure form, structure Rationally, reduce heat shield connection structural member quantity, have the advantages that easy to operate.

Specific embodiment

This structure utility model is further described in the following with reference to the drawings and specific embodiments, but not that should not understand with regard to this It is only limitted to embodiment below for the range of theme described in this structure utility model, is not departing from the above-mentioned skill of this structure utility model Under the art state of mind, all various modifications made according to ordinary skill knowledge and customary means, replacement and change are wrapped It includes in the range of this structure utility model.

As shown in Fig. 1, Fig. 1-1 and Fig. 2, the utility model includes belt variable shape bifurcated (also being understood as elastic bayonet lock) 2 structure of locking key, 4 structure of guide base with guiding and limit function, 3 structure of lock pin that can be riveted.

If 2 structure of locking key of Fig. 3, belt variable shape bifurcated (also being understood as elastic bayonet lock) are located in guide base 4, rear end Forward and backward pulling locking key 2 is convenient in bending, and the deformable bifurcated in front end (also being understood as elastic bayonet lock) is used for clamping lock pin 3.

Such as Fig. 4,4 structure rear end sides of guide base form guide groove in " [font " crimp, lead to the movement of locking key 2 To and limit, opened round through-hole is for the loading of lock pin 3 among the front end of bottom surface.

As shown in figure 5,3 structure of lock pin that can be riveted, lower blind bore is used to rivet with heat-insulated cover body 1, upper, annular slot Cooperate with locking key 2 and realizes locking.

The utility model use process is as follows:

1, as shown in Fig. 1, Fig. 1-1, there is the guide base 4 of limit and guide function to be welded on heat-insulated cover body 1；

2. as shown in Figure 1, shown in Figure 5,3 lower part of lock pin that can be riveted is riveted on heat-insulated cover body 1；

3. as shown in FIG. 1 to 3, lock pin 3 is packed into from 4 front end tapping of guide base, locking key 2 is from guide base

After 4 rear side is packed into, the bending section by being pulled along 2 rear end of locking key makes the deformable bifurcated of locking key 2 be caught in lock pin 3 Top annular groove, realize the connection of heat shield.
