In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model comprises a front shell, a through rod, a sealing ring and a guide rod nut; the guide rod nut is in a step shape, a through hole is formed in the middle of the guide rod nut, a thread is arranged at one end in the hole, the other end of the guide rod nut is close to the front shell and is machined into a V-shaped conical surface groove, the front shell is provided with a through hole, and the periphery of the through hole is a plane; the sealing ring is arranged in the V-shaped conical surface groove and is positioned among the penetrating rod, the guide rod nut and the front shell.
The surfaces of the front shell and the V-shaped conical surface groove of the guide rod nut are in interference fit with the sealing ring, so that a sealing effect is achieved.
The sealing ring is of an O-shaped or rectangular annular structure.
The penetrating rod threads are matched with the guide rod nuts in a threaded mode and then fixed through anaerobic adhesive.
The utility model has the advantages that:
the utility model discloses compare with the tradition and run through the pole structure, relative position accessible helicitic texture between guide-bar nut and the guide arm is adjusted to can be used for the booster of different thickness. The utility model discloses can save material, improve the part range of application, reduce cost.
The utility model discloses commonality is high, cost reduction, material saving.
Drawings
The invention will be further described with reference to the accompanying drawings and specific embodiments:
fig. 1 is the overall structure assembly diagram of the present invention.
Fig. 2 is a partial view of the structure of the present invention.
In the figure: 1. the booster comprises a front shell, a sealing ring, a penetrating rod, a guide rod nut, a booster assembly and a shell, wherein the front shell 2 is provided with a sealing ring, 3 is provided with a penetrating rod, 4 is provided with a guide rod nut, and 5 is provided with a booster assembly.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the booster assembly 5 includes a front case 1 and a through rod 3 therein; the booster assembly 5 also comprises a sealing ring 2 and a guide rod nut 4; the penetrating rod 3 is a straight rod and is penetratingly installed in the booster assembly 5, and one end of the penetrating rod is connected to the front case 1.
As shown in fig. 2, the outer wall of the penetrating rod 3 near the front shell 1 is provided with a thread, the leader nut 4 is sleeved outside the thread of the penetrating rod 3, the leader nut 4 is in a step shape, the middle of the leader nut is provided with a through hole, one end of the through hole is provided with a thread, the other end of the leader nut is near the front shell 1 and is processed into a V-shaped conical groove, the front shell 1 is provided with a through hole, and the periphery of the through hole is a plane; sealing washer 2 is installed in V type conical surface groove, is located between penetrating rod 3, guide-bar nut 4 and procapsid 1, guide-bar nut 4V type conical surface groove surface are in interference fit with sealing washer 2, play sealed effect.
During installation, a section of the middle thread of the penetrating rod 3 is matched with a threaded hole of the guide rod nut 4, the sealing ring 2 is sleeved into the penetrating rod and is placed into a V-shaped groove of the guide rod nut 4 to be matched with a V-shaped groove surface, then the front shell 1 is sleeved into the penetrating rod 3 through a through hole of the front shell 1, so that the inner surface of the front shell 1 is matched with the sealing ring 2 and is abutted against one end plane of the V-shaped groove of the guide rod nut 4.
The utility model discloses a concrete implementation working process:
when the booster runs through the pole assembly, with guide arm nut 4 through the hole screw thread packing in the middle of non-V profile one end in running through pole 3, with run through pole 3 go up screw-thread fit, later embolia through pole 3 and with guide arm nut 4V profile cooperation with sealing washer 2, then embolia through the through-hole with procapsid 1 in running through pole 3 to with the laminating of guide arm nut 4V type groove one end terminal surface, make procapsid 1 surface and guide arm nut 4V profile be in interference fit with sealing washer 2, reach sealed effect. Wherein the relative position of the through rod 3 and the front case 1 is adjusted by the screw thread between the leadscrew nut 4 and the through rod 3.
The above detailed description is provided for illustrative purposes, and is not intended to limit the present invention, and any modifications and variations of the present invention are within the spirit and scope of the following claims.
