Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses female head of fire control pipeline meet soon.

Example 1:

referring to fig. 1 and 2, a female head of fire control pipeline meet soon is including being pipe form connecting pipe 1, offers the spout 2 that the cross-section is the rectangle on connecting pipe 1 tip lateral wall, and the one end that spout 2 is close to connecting pipe 1 inside wall is uncovered setting. The end part of the connecting pipe 1 close to the chute 2 is provided with a connecting baffle 3 with a rectangular section, and the connecting baffle 3 extends along the length direction of the chute 2. A notch 4 is arranged at the end part of the connecting baffle 3 close to the chute 2. In use, the projection on the male moves from the notch 4 into the chute 2 and the male is rotated to slide the projection to the end of the chute 2 remote from the notch 4. The lateral wall of spout 2 and linking stop 3 carry on spacingly to the arch to make public head and female first interconnect.

A pair of mounting seats 5 are arranged on the circumferential side wall of the connecting pipe 1, a long circular truncated cone-shaped wrench 6 is rotatably arranged on the pair of mounting seats 5 through a rotating shaft, the cross section of the wrench 6 is gradually reduced along the direction far away from the connecting pipe 1, and a spherical stop block 7 is arranged at one end of the wrench 6 far away from the connecting pipe 1. The spanner 6 is provided with limiting cam 8 near one end of the connecting pipe 1, and the limiting cam 8 and the spanner 6 are vertically arranged along the rotating direction. The side wall of the sliding groove 2 far away from the connecting baffle 3 is provided with a notch, the notch penetrates through the side wall of the connecting pipe 1, and the limiting cam 8 is positioned on the connecting pipe 1 and slides in the notch.

When the wrench 6 is perpendicular to the wall of the connecting pipe 1, at this time, the limiting cam 8 is located in the notch, the protrusion on the male head is moved into the sliding groove 2 from the notch 4, and the male head is rotated to enable the protrusion to slide to one end of the sliding groove 2, which is far away from the notch 4. Rotate spanner 6 along the direction of keeping away from connection baffle 3, rotate spanner 6 to with connecting pipe 1's axial direction parallel time, spacing cam 8 rotates out from the incision, and spacing cam 8 rotates to spout 2 in, stops the bellied rotation of public head in the spout 2 to it is stable to make public head and female head keep connecting.

The connecting pipe 1 is provided with a U-shaped elastic steel sheet 9 on the peripheral side wall, the elastic steel sheet 9 is fixed between the pair of mounting seats 5, and the opening of the elastic steel sheet 9 faces the connecting baffle 3. An abutting block 10 in a rectangular shape is fixedly arranged at one end of the wrench 6 close to the connecting pipe 1, the abutting block 10 and the elastic steel sheet 9 are abutted against each other, and the abutting block 10 in the embodiment is a stainless steel block. When the wrench 6 is perpendicular to the connection pipe 1, a right-angle surface 11 of the abutting block 10 away from the wrench 6 abuts against the elastic steel sheet 9, and the wrench 6 is kept perpendicular to the connection pipe 1 under the elastic force of the elastic steel sheet 9. When spanner 6 rotated to with connecting pipe 1 axial direction parallel along the direction of keeping away from connecting baffle 3, another right angle face 11 supported tightly each other with elastic steel sheet 9 on the butt piece 10, and under the effect of elastic steel sheet 9 elastic force, made spanner 6 keep being on a parallel with connecting pipe 1 axial setting, and then made spacing cam 8 keep blockking public first bellied.

The juncture of the two right-angle surfaces 11 abutted against the elastic steel sheet 9 on the abutting block 10 is provided with an arc surface 12, when the spanner 6 rotates to drive the abutting block 10 to rotate on the elastic steel sheet 9, the arc surface 12 plays a certain guiding role for the abutting block 10, and the abutting block 10 is convenient to rotate on the elastic steel sheet 9.

The implementation principle of the embodiment 1 is as follows: when the spanner 6 is in and connecting pipe 1 is perpendicular, spout 2 is kept away from to spacing cam 8, removes the arch on the public head to spout 2 from breach 4, rotates public head and makes the arch keep away from breach 4 in spout 2, and the lateral wall of spout 2 is fixed with protruding with connection baffle 3 to make public head and female head keep connected. Rotate spanner 6 to parallel with 1 axial of connecting pipe along the direction of keeping away from connection baffle 3, at this moment, spacing cam 8 rotates in the incision to the lateral wall of spout 2, stops the arch in spout 2, improves the stability that public head and female head are connected. The limiting block on the wrench 6 and the elastic steel sheet 9 on the side wall of the connecting pipe 1 are mutually abutted tightly, so that the limiting cam 8 is kept away from the sliding groove 2 and is in one of two states in the sliding groove 2, and the connection stability of the male head and the female head is further improved.

Example 2:

referring to fig. 3 and 4, the difference between this embodiment and embodiment 1 is that a self-locking screw 13 is disposed to penetrate in an axial direction of the wrench 6, the self-locking screw 13 is in threaded connection with the wrench 6, one end of the self-locking screw 13 close to the connecting pipe 1 is located between the limit cam 8 and the abutment block 10, and one end of the self-locking screw 13 far from the connecting pipe 1 is fixedly connected to the stopper 7. The clamping plate 14 is arranged on the peripheral side wall of the connecting pipe 1, the clamping plate 14 is positioned between the pair of mounting seats 5 and close to one end of the connecting baffle 3, the clamping plate 14 is perpendicular to the connecting pipe 1, and the section of the clamping plate 14 is rectangular. A hemispherical engaging groove 15 is formed on the side wall of the engaging plate 14 close to the mounting seat 5.

When spanner 6 rotated to being parallel with connecting pipe 1 along the direction of keeping away from connecting baffle 3, rotated dog 7 and made auto-lock screw 13 rotate in spanner 6, auto-lock screw 13 rotate to with the joint groove 15 mutual joint on the joint board 14 to lock spanner 6, make spacing cam 8 keep blockking dog 7 to public head, thereby keep the stability that public head and female head are connected.

Set up compression elastic component 16 on auto-lock screw rod 13 between spanner 6 and dog 7, compression elastic component 16 in this embodiment can be compression spring, and under the effect of the elastic restoring force of compression elastic component 16, auto-lock screw rod 13 and spanner 6 keep supporting tight state, have reduced the not hard up condition of auto-lock screw rod 13 in spanner 6, and then have improved the stability that public head and female head are connected.

A plurality of hold-down bolts 17 are arranged on the side wall of the connecting baffle 3 far away from the connecting pipe 1, the hold-down bolts 17 are in threaded connection with the connecting baffle 3, and the number of the hold-down bolts 17 in this embodiment may be two. After the male head and the female head are stably connected, the compression bolt 17 is screwed to enable the compression bolt 17 to be tightly abutted to the protrusion, so that the male head is fixed in the groove of the female head, and the connection stability of the male head and the female head is improved.

The principle of the embodiment 2 is as follows: after the male head and the female head are stably connected, the self-locking screw 13 is rotated through the stop block 7, so that the self-locking screw 13 is mutually clamped with the clamping groove 15 on the clamping plate 14, and the wrench 6 is locked. And the compression bolts 17 on the connecting baffle 3 are screwed down, so that the compression bolts 17 fix the bulges on the male head, and the stability of connection between the male head and the female head is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
