Description
Technical field
The present invention relates to mechanical spare and accessory parts technical field more particularly to a kind of flexible pins of special adjustable in length.
Background technology
Pin is one of common spare and accessory parts in mechanical equipment, and main function is the relative position of two parts in order to prevent
The changing of the relative positions.Different size of pin is needed to be fastened between different parts, it is therefore desirable to various sizes of pin.Especially
It is in same equipment, numerous pins can bring assembly working certain trouble, not only waste time but also cost of idleness.
Invention content
The object of the present invention is to provide a kind of flexible pins of special adjustable in length, when in use can be right as needed
The length of pin carries out free adjusting, enables it to be suitable for larger range of application demand, makes pin as far as possible in use
Nail type is reduced to minimum, makes worker be unlikely to take pin by mistake in assembling and wastes time, effectively increases in assembling process
Efficiency of assembling, this part can be adjusted when carrying out length adjustment by conventional tool, adjust more convenient, be made
It uses more flexible.
Technical scheme is as follows：
A kind of flexible pin of special adjustable in length, it is characterised in that：Including cylindrical pin shaft body, the right side
The connection of side center is connected with cylindrical end portion there are one cylindrical pin axle center on the left of the pin shaft body,
The diameter of the first end is more than the pin shaft body, and the pin axle center can do axis relative to the pin shaft body
To movement, the second main body of cylindrical pin is connected on the right side of the pin axle center, the right end of the second main body of the pin is equipped with
Integrally formed cylinder the second end, the diameter of the second end is identical as the diameter of the first end, the pin
The diameter of shaft body is identical as the diameter of the second main body of the pin, and the Left-side center position of the first end, which is equipped with, can control
Institute may be implemented by the rotation process to the pushing handle telescopic control mechanism in the pushing handle telescopic control mechanism of pin axle center collapsing length
State axial movement of the pin axle center relative to the pin shaft body.
Further, it is 50mm that the pushing handle telescopic control mechanism, which can control the minimum value of pin axle center collapsing length,
It is 200mm that the pushing handle telescopic control mechanism, which can control the maximum value of pin axle center collapsing length,.
Further, the external cylindrical surface upper and lower ends of the pin shaft body are respectively equipped with a rectangle positioning key,
The external cylindrical surface upper and lower ends of the second main body of the pin are also respectively equipped with a rectangle positioning key.
Beneficial effects of the present invention：
The present invention can carry out free adjusting to the length of pin as needed when in use, enable it to be suitable for bigger
The application demand of range is in use reduced to as far as possible pin type minimum, and worker is made to be unlikely to take by mistake in assembling
Pin and waste time, effectively increase the efficiency of assembling in assembling process, this part can pass through when carrying out length adjustment
Conventional tool is adjusted, and adjusts more convenient, uses more flexible.
Description of the drawings
Fig. 1 is the side structure schematic diagram of the present invention；
Fig. 2 is the positive structure schematic of the present invention；
In figure：1, pin shaft body, 2, pin axle center, 3, the second main body of pin, 4, first end, 5, the second end, 6,
Positioning key, 7, pushing handle telescopic control mechanism.
Specific implementation mode
As depicted in figs. 1 and 2, the flexible pin of a kind of special adjustable in length, it is different from traditional pin, is using
When can free adjusting be carried out to the length of pin as needed, it is more convenient in use, enable it to suitable for more
Large-scale application demand is in use reduced to as far as possible pin type minimum, and worker is made to be unlikely to take in assembling
Wrong pin and waste time, effectively increase the efficiency of assembling in assembling process.This part can lead to when carrying out length adjustment
Conventional tool is crossed to be adjusted, adjust get up it is more convenient, use more flexible.It includes cylindrical pin shaft body 1,
There are one cylindrical pin axle center 2 for the right center position connection, it can be being done as needed relative to pin main body
Relative position adjust.The left side of the pin shaft body 1 is connected with cylindrical end portion 4, the diameter of the first end 4
More than the pin shaft body 1, the pin axle center 2 can axially move relative to the pin shaft body 1, the pin
The right side in axle center 2 is connected with the second main body of cylindrical pin 3, and the right end of the second main body of the pin 3 is equipped with integrally formed circle
Cylindricality the second end 5, the diameter of the second end 5 is identical as the diameter of the first end 4, the pin shaft body 1
Diameter is identical as the diameter of the second main body of the pin 3, keeps the size at left and right sides of pin identical, structural strength when in use
More preferably, stress evenly, can make its stability in use more preferable, the service life is longer.The first end 4
Left-side center position is equipped with the pushing handle telescopic control mechanism 7 that can control 2 collapsing length of pin axle center, by the extension and contraction control
Axial movement of the pin axle center 2 relative to the pin shaft body 1 may be implemented in the rotation process of mechanism 7, is being grown
It is more convenient when degree is adjusted, the type of pin in use is effectively reduced, the efficiency of assembling in assembling process is improved.
Preferably, the controllable 2 collapsing length minimum value of the pin axle center of the pushing handle telescopic control mechanism 7 is
50mm, the controllable 2 collapsing length maximum value of the pin axle center of the pushing handle telescopic control mechanism 7 are 200mm.To make this pin
Nail can apply the demand of different length, use scope wider.
Preferably, the external cylindrical surface upper and lower ends of the pin shaft body 1 are respectively equipped with a rectangle positioning key
6, the external cylindrical surface upper and lower ends of the second main body of the pin 3 are also respectively equipped with a rectangle positioning key 6, make it into luggage
Timing can more preferably carry out assembly positioning, more efficient when making assembly, assemble up more convenient, the connective stability after assembly
Also relatively reliable.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements or replace, these improve or replace
It should be regarded as protection scope of the present invention.
