Abstract
A steel ball fabrication hole plug comprises a fabrication hole, a threaded hole A, at least one steel ball and a headless screw, wherein the bottom hole of the threaded hole A is larger than the fabrication hole, the diameter of the steel ball is larger than that of the fabrication hole and smaller than that of the bottom hole of the threaded hole A, an installation slotted hole is formed in the top end of the headless screw, and the bottom of the screw is a planar bottom. The utility model discloses a radial dimension of end cap is very little, dismouting moreover can be repeated.
Description
Technical Field
The utility model belongs to the technical field of the valve block, concretely relates to steel ball fabrication hole end cap.
Background
In the process of valve block, fabrication holes are often needed to be processed, and the fabrication holes need to be blocked by plugs.
In some relatively compact locations it is desirable that the radial dimension of the plug be as small as possible and that the plug be capable of repeated disassembly and assembly.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a steel ball fabrication hole end cap adopts technical scheme as follows:
a steel ball fabrication hole plug comprises a fabrication hole, a threaded hole A, at least one steel ball and a headless screw, wherein the bottom hole of the threaded hole A is larger than the fabrication hole, the diameter of the steel ball is larger than that of the fabrication hole and smaller than that of the bottom hole of the threaded hole A, an installation slotted hole is formed in the top end of the headless screw, and the bottom of the headless screw is a planar bottom.
Preferably, the bottom of the headless screw is a circular arc-shaped bottom.
Preferably, the mounting slot hole is a cross-shaped counter bore or a countersunk threaded hole B.
The utility model has the advantages that:
1. the radial dimension of the plug is very small and the plug can be repeatedly disassembled and assembled.
2. The steel ball and the headless screw can both use standard parts, so that the cost can be reduced.
Drawings
Fig. 1 is a schematic structural view of embodiment 1 of the present invention;
fig. 2 is a schematic structural view of embodiment 2 of the present invention;
in the figure: 1. a threaded hole A; 2. headless screws; 3. a circular arc-shaped bottom; 4. steel balls; 5. a fabrication hole; 6. a countersunk head threaded hole B; 7. a cross-shaped counter bore; 8. a planar bottom.
Detailed Description
The present invention will be further described with reference to specific embodiments.
Example 1
As shown in fig. 1, the steel ball fabrication hole plug comprises a fabrication hole, a threaded hole a, a steel ball and a headless screw, wherein a bottom hole of the threaded hole a is larger than the fabrication hole, the diameter of the steel ball is larger than the diameter of the fabrication hole and smaller than the diameter of the bottom hole of the threaded hole a, a countersunk head threaded hole B is formed in the top end of the headless screw, and the bottom of the headless screw is an arc-shaped bottom.
Specifically, after a fabrication hole is machined in a valve block, a threaded hole A with a bottom hole larger than the fabrication hole is machined, and a steel ball larger than the fabrication hole and smaller than a threaded bottom hole is placed in the threaded hole A; and then a screwdriver is used for propping against the countersunk head threaded hole B to screw down the headless screw, and the steel ball is pressed tightly.
Example 2
The difference between the embodiment and the embodiment 1 is that the number of the steel balls is 2, the top end of the headless screw is provided with a cross-shaped counter bore, and the bottom of the headless screw is a plane bottom.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Claims (3)
