Abstract

The utility model relates to an assembly tool, and provides a base dismantling device for solving the technical problems. The base dismantling device can uniformly dismantle and remove a base assembly of some product from a shell and is conveniently and reliably operated. The base dismantling device is characterized by mainly comprising three pull rods (1), three connecting rods (2), a threaded connecting ring (3), a connecting ring (4) and a locking pull nail (5). The base dismantling device is of a three-jaw puller structure and is used for dismantling a base through three screw holes on the base, thus the whole structure is light and convenient, and one person can operate the base dismantling device.

Description

A kind of base provision for disengagement

Technical field

The utility model relates to assembling and uses frock.

Technical background

Certain type product bottom is connected through three place's screws with shell by the unsplit bedplate assembly, shown in Fig. 1, Fig. 2 (a), Fig. 2 (b).In the accompanying drawing: 11 is shell; 12 is base assembly.

Final products are in place after putting the sealing of " O " type circle by base assembly, and trip bolt and gluing.Like accompanying drawing 2 (a), Fig. 2 (b), 13 is " O " type circle among the figure.

Owing to after assembly is installed, need repeat debugging, therefore, often need base be dismantled in the use; In the base part, except that three place's screw holes, remainder is all shiny surface; The no point of application, after therefore in a single day " O " type circle was in place, extremely difficulty was dismantled base assembly.Therefore, need design one cover provision for disengagement, can exert oneself uniformly base assembly to be taken apart to debug, and require operation convenient, safe and reliable.

The utility model content

The utility model technical problem to be solved is to provide a kind of base provision for disengagement, can uniformly certain type product base assembly be peeled off by the shell dismounting, and operation is convenient reliable.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of base provision for disengagement is characterized in that: said device mainly is made up of three pull bars 1, three connecting rods 2, screw shackle 3, connecting ring 4, a locking blind rivet 5; Said device is a central shaft with locking blind rivet 5; Connecting ring 4 is installed on said locking blind rivet 5 tops, and connecting ring 4 centers are provided with tapped through hole, is connected with locking blind rivet 5 through screw thread; Screw shackle 3 is installed in said locking blind rivet 5 bottoms; The upper end of said three pull bars 1 is connected through the edge movable of rotating shaft with connecting ring 4; The middle part of said three pull bars 1 is connected to form the Three-claw pull-horse structure through the edge movable of three connecting rods 2 and screw shackle 3 respectively, and the lower end of said three pull bars 1 is for going deep into the drag hook shape of screw hole.

The utility model can bring following beneficial effect:

This device design Three-claw pull-horse structure is carried out the base dismounting by 3 place's screw holes on the base, and overall structure is lightly convenient, and a people can operate.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

Because certain type product base bottom is smooth, except that screw mounting hole, does not have the point of application capable of using, dismounting can only be used this three places point of application; So the design drag hook gos deep into screw hole, and lock fastening; Version is used and is drawn the horse structure, and design 3 pawls and draw horse, the locking base, and dismantle separation.

Shown in Fig. 3 (a), Fig. 3 (b), Fig. 3 (c), 1 is pull bar among the figure, and 2 is connecting rod, and 3 is screw shackle, and 4 is connecting ring, and 5 are the locking blind rivet.

Referring to Fig. 4 (a), Fig. 4 (b), dismounting is during base, three pull bars colluded stretch into that three place's screw hole to baseplanes contact on the base earlier.The locking blind rivet of screwing draws three pulling claws in, and evenly locking is on disassembly mechanism with base, and shift mechanism evenly takes out base.

Claims
