The present utility model may be further configured in a preferred example to: the cross section diameter of the first through hole is 0.1-0.25 times of the cross section diameter of the cylindrical pin.
In summary, the present utility model includes at least one of the following beneficial technical effects:
1. through having seted up first through-hole on the cylindric lock, when making the cylindric lock install in the blind hole structure, inside outside atmospheric pressure of blind hole structure is the same, makes things convenient for operating personnel to install the cylindric lock in place fast, and avoids the cylindric lock after the installation to take place to pop out the phenomenon of blind hole structure, improves the success rate of assembly and the intensity of this structure after the assembly.
2. Screw threads are formed on the inner peripheral wall of the first through hole, a screw is arranged in the first through hole, the cylindrical pin is assembled in the blind hole structure, the screw seals the first through hole, so that a closed space is formed inside the first through hole, dust impurities and the like are prevented from entering the blind hole structure through the first through hole, and the connection firmness of the cylindrical pin and the blind hole structure is enhanced again.
3. Through being provided with the sealant, inside screw rod and screw in first through-hole, make the area that the sealant occupied enlarge, and then plug up the gap between screw thread and the screw rod, further improve the leakproofness of the inside space of first through-hole.
Drawings
FIG. 1 is a schematic view of the overall structure of the present embodiment;
fig. 2 is a schematic view of the semi-sectional structure of fig. 1.
In the figure, 1, a cylindrical pin; 11. a threaded blind hole; 2. a first through hole; 3. a stabilizing assembly; 31. and (3) a screw.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
Examples:
referring to fig. 1-2, the cylindrical pin 1 with stable assembly disclosed by the utility model comprises the cylindrical pin 1. A threaded blind hole 11 is formed in the center of the top of the cylindrical pin 1.
The bottom of the inner wall of the threaded blind hole 11 is provided with a first through hole 2. The cross section of the first through hole 2 is circular, and the projection of the horizontal plane of the center of the cross section of the first through hole 2 coincides with the projection of the horizontal plane of the circular cross section of the cylindrical pin 1. The inside of the first through hole 2 is communicated with the inside of the threaded blind hole 11.
The first through hole 2 is provided with a stabilizing component 3.
The upper half of the inner peripheral wall of the first through hole 2 is threaded. The length of the thread segments in the first through hole 2 is 0.3-0.5 times the length of the first through hole 2. The cross-sectional diameter of the first through hole 2 is 0.1-0.25 times of the cross-sectional diameter of the cylindrical pin 1.
The stabilizing assembly 3 comprises a screw 31, the screw 31 is completely located in the first through hole 2, and the screw 31 is in threaded connection with the first through hole 2.
The thread of the first through hole 2 is coated with sealant.
The implementation principle of the embodiment is as follows:
when the operator needs to fit the cylindrical pin 1 into the fitting hole, the screw 31 is not in the first through hole 2 at this time. When the cylindrical pin 1 is placed in the matching hole by an operator, the air extruded in the matching hole moves to the outside of the matching hole along the inside of the first through hole 2 and the inside of the threaded blind hole 11.
After the cylindrical pin 1 is fully positioned in the mating hole, an operator uses a tool to screw the screw 31 into the first through hole 2. When the screw 31 is screwed into the first through hole 2, the sealant is filled into the gap between the internal thread of the first through hole 2 and the screw 31, so that the tightness of the space in the sealed hole is ensured.
When the operator needs to take out the cylindrical pin 1, the operator first uses a tool to take out the screw 31 from the first through hole 2, and then uses a specialized tool to take out the cylindrical pin 1 from the assembly hole.
The embodiments of the present utility model are all preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
