Detailed Description

The invention will be further described with reference to the following specific embodiments:

example 1:

as shown in fig. 1-3, the utility model discloses a magnetism is inhaled, stealthy fast-assembling connecting piece, the connecting piece includes sleeve 1, sets up expansion portion 14 on the sleeve 1 front end, can insert bolt 2, shaping on the sleeve 1 rear end are in connecting portion 21 and the setting of bolt 2 rear end are in make between sleeve 1 and the bolt 2 fixed connection is inhaled to magnetism in sleeve 1 fixed knot and is constructed 3, the front end of sleeve 1 is fixed on the panel I6 that needs to connect through expansion portion 14 connection, the rear end of bolt 2 is fixed on the panel II 7 that needs to connect through connecting portion 21 connection, the connecting portion 21 of bolt 2 can be called bolt or screw pattern, the connecting piece passes through magnetism is inhaled fixed knot and is constructed 3 and make bolt 2 can be quick assembly disassembly in sleeve 1, can save and use traditional connection fixed mode such as bolt, nut, eccentric wheel, nut, swiftly more convenient, connect panel I6 and panel II 7, makes the outside cleaner and tidier, pleasing to the eye, reaches the stealthy effect of hiding connection structure simultaneously.

Example 2:

the difference from example 1 is that: the magnetic attraction fixing structure 3 comprises a metal key pin 31 which can enter from the slot hole 11 and is clamped between the annular recess 22 and the slot hole 11, the key pin 31 is clamped between the slot hole 11 of the sleeve 1 and the annular recess 22 of the bolt 2, the pin and the slot hole 11 cannot move relative to each other, and the bolt 2 is connected and fixed in the sleeve 1.

Example 3:

the difference from example 2 is that: in order to prevent the key pin 31 from easily falling into the sleeve 1, a stop step 12 for limiting the key pin 31 is formed in the groove hole 11, and both sides of the key pin 31 are engaged with the stop step 12, so that the key pin 31 cannot fall into the sleeve 1.

Example 4:

the difference from example 3 is that: the magnetic attraction fixing structure 3 further comprises an elastic ferrule 32 for enabling the key pin 31 to automatically return, the elastic ferrule 32 can be a rubber ring, a rubber belt or the like, the elastic ferrule 32 is sleeved on the slotted hole 11 of the sleeve 1 and the key pin 31, and the elastic ferrule 32 is in contact connection with the key pin 31.

When the key pin 31 moves upwards under the action of magnetic attraction and is separated from the original clamping position, the key pin 31 stretches the elastic ferrule 32; when the key pin 31 loses the magnetic attraction function, the key pin moves downwards under the elastic force of the elastic ferrule 32 and returns to the clamping position or the stop step 12 again.

Example 5:

the differences from example 4 are: the sleeve 1 and the slot 11 thereof are formed with an annular groove 13 for positioning the elastic ferrule 32, the key pin 31 is formed with a groove 311 for positioning the elastic ferrule 32, the positions of the annular groove 13 on the sleeve 1 and the groove 311 on the key pin 31 are on the same radial plane, the elastic ferrule 32 can be limited to be positioned in the annular groove 13 on the sleeve 1 and the slot 11 and the groove 311 on the key pin 31, and the return of the key pin 31 cannot be influenced by displacement.

Example 6:

the difference from example 2 is that: the rear end of the key pin 31 is formed with a guide inclined plane 312, the front end of the bolt 2 is formed with a top block 23 matched with the guide inclined plane 312, the guide inclined plane 312 enables the key pin 31 to move upwards under the action of the top block 23, and the original clamping position is separated, namely when the bolt 2 is inserted into the sleeve 1, the top block 23 at the front end of the bolt 2 acts on the guide inclined plane 312, so that the key pin 31 moves upwards, the insertion of the bolt 2 is not hindered, and after the bolt 2 reaches a certain depth position for connection, the key pin 31 moves downwards again and is clamped between the slotted hole 11 of the sleeve 1 and the annular recess 22 of the bolt 2, so that the bolt 2 is fixedly connected with the sleeve 1, and cannot be separated under the action of no external magnetic attraction force.

Example 7:

the difference from example 1 is that: the rear end shaping of sleeve 1 has the internal diameter to be greater than the reaming groove 15 in sleeve 1's aperture, the shaping has the external diameter to be greater than before the rear end connecting portion 21 of bolt 2 the step axle 24 of the axle footpath of bolt 2, the external diameter of step axle 24 is greater than sleeve 1's aperture is less than the internal diameter in reaming groove 15 makes step axle 24 plug bush can in reaming groove 15, works as step axle 24 plug bush is in behind the reaming groove 15, bolt 2 can promote sleeve 1 moves forward, finally step axle 24 plays spacing effect with reaming groove 15.

Example 8:

the differences from examples 1 or 7 are: the expansion part 14 at the front end of the sleeve 1 comprises a spring fork tine molded at the front end of the sleeve 1 and an expansion piece 4 inserted into the spring fork tine and used for expanding the spring fork tine, the expansion piece 4 is molded into a trapezoid, a plurality of barbs 41 are molded on the outer surface of the expansion piece 4, a plurality of latch teeth 141 connected with the barbs 41 in a clamping manner are molded on the inner surface of the spring fork tine, and after the spring fork tine is connected with the expansion piece 4, the spring fork tine is connected with the latch teeth 141 through the matching of the barbs 41. The resilient tines expand and resist within the sheet material i 6 to be joined as the enlarged section 4 is inserted, and the greater the extent of the enlargement, the greater the strength of the resistance.

Example 9:

the difference from example 8 is that: a plurality of inverted teeth 142 are formed on the outer surface of the elastic fork tooth, so that the elastic fork tooth is connected with the inner part of the plate I6 to be connected more firmly.

The working principle is as follows:

as shown in fig. 4, a key pin 31 and an elastic ferrule 32 are put into the slotted hole 11 of the sleeve 1, the expanding piece 4 and the assembled sleeve 1 are put into the preset hole of the plate I6 in sequence, and the front end of the sleeve 1 is inserted into the preset hole; fixing the rear end of the bolt 2 in a preset hole of the plate II 7; and connecting the plate II 7 with the bolt 2 with the plate I6 with the sleeve 1.

As shown in fig. 5-7, the front end of the bolt 2 is inserted from the rear end of the sleeve 1, after the front end of the bolt 2 reaches the guide slope 312 of the key 31, the bolt 2 jacks up the key 31 and continues to insert forwards, and when a certain depth is reached (the front end of the bolt 2 resists against the expansion part 14 and the expanding piece 4 at the front end of the sleeve 1 to make the expansion part expand and be clamped in the plate material i 6), the key 31 falls back to the annular recess 22 of the bolt 2 under the action of the elastic ferrule 32, so that the bolt 2 and the sleeve 1 are clamped and fixed.

As shown in fig. 8-11, to remove the plate, the magnet 5 is placed on the plate i 6 at the position where the key 31 is provided, the key 31 is attracted, and the key 31 is separated from the locking position of the plug 2 and the sleeve 1, so that the plug 2 can be pulled out from the sleeve 1, even if the plate ii 7 and the plate i 6 are separated from each other.
