Description

Technical Field

[0001] This utility model relates to the field of foam gun technology, specifically a portable fire-fighting foam gun. Background Technology

[0002] Foam guns, as portable firefighting equipment, are mainly composed of components such as barrel, handwheel, gun body, ball valve, and suction pipe. They generate air foam by creating a negative pressure mixture of foam liquid and air through high-pressure water flow. The equipment can also be connected to fire hoses or foam hydrants.

[0003] However, in actual use, the barrel length of existing foam guns is often too long, making it difficult to fully insert the foam gun into narrow containers, thus making the foam gun difficult to carry. In view of this, we propose a portable fire-fighting foam gun. Utility Model Content

[0004] The purpose of this invention is to provide a portable fire-fighting foam gun to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable fire-fighting foam gun, comprising a gun body, a water inlet at the side end of the gun body, a foam inlet at the lower outer wall of the gun body, a water outlet pipe threadedly connected to the end of the gun body away from the water inlet, a handle fixedly connected to the outer wall of the gun body, a retaining ring fixedly connected to the lower outer wall of the water outlet pipe, and a connecting assembly provided on the outside of the water outlet pipe, the connecting assembly comprising:

[0006] A threaded sleeve is fixedly connected to the outer wall of the water outlet pipe. A threaded groove is provided on the outer wall of the gun body. A plug is fixedly connected to the lower outer wall of the water outlet pipe.

[0007] A fixing block is fixedly connected to the outer wall of the gun body. A locking block is fixedly connected to the outer wall of the insertion block. The locking block passes through the outer wall of the fixing block and is slidably connected to the inner wall of the fixing block. A locking plate is slidably connected to the inner wall of the fixing block. The locking plate passes through the outer wall of the locking block.

[0008] A spring is fixedly connected to the end of the locking plate away from the locking block. A pull rod is fixedly connected to the end of the locking plate away from the locking block. The end of the pull rod away from the locking plate passes through the fixing block and is fixedly connected to a pull plate.

[0009] Preferably, the outer wall of the fixing block has a through slot that matches the size of the locking block, and the locking block is slidably connected to the inner wall of the slot, so that the water outlet pipe that is separated from the gun body can be fixed by inserting the locking block into the slot.

[0010] Preferably, the outer wall of the card block has a locking groove that matches the locking plate. The locking plate penetrates the inner wall of the card groove and engages with the locking groove, so that when the card block is inserted into the card groove, the locking plate can be inserted into the locking groove to fix the card block and keep the card block in the fixed block.

[0011] Preferably, the end of the locking block away from the insert block has an inclined surface, and the end of the locking plate near the locking block has an inclined surface with the same slope as the insert block. The inclined surface on the locking plate fits into the inclined surface on the locking block. When the locking block is directly inserted into the slot, the inclined surface of the locking block pushes the inclined surface on the locking plate, causing the locking plate to push the spring to contract. When the locking slot is directly opposite the locking plate, the locking plate pops out and engages with the locking slot, thus fixing the locking block in place.

[0012] Preferably, the end of the spring away from the locking plate is fixedly connected to the inner wall of the fixing block, and the spring is sleeved on the outer wall of the pull rod. When the pull plate is pulled, the pull rod can drive the locking plate to compress the spring. At this time, the locking plate leaves the locking groove on the locking block, so that the locking block can disengage from the fixing block.

[0013] Preferably, a fixing ring is fixedly connected to the outer wall of the gun body, and a threaded groove is formed on the outer wall of the fixing ring. The threaded sleeve is threadedly connected to the inner wall of the threaded groove. The threaded sleeve and the threaded groove are respectively set on the arc-shaped outer wall of the water outlet pipe and the arc-shaped outer wall of the gun body, so that the water outlet pipe can be threadedly connected to the gun body through the cooperation of the threaded sleeve and the threaded groove. The threaded sleeve and the threaded groove are respectively set on the arc-shaped outer wall of the water outlet pipe and the arc-shaped outer wall of the gun body.

[0014] Preferably, the opening diameter of the retaining ring is the same as the diameter of the handle, and the retaining ring engages with the outer wall of the handle, so that when the water pipe is fixed, one end of the water pipe is fixed to the gun body and the other end of the water pipe is fixed to the handle, so that both ends of the water pipe can be fixed.

[0015] Compared with the prior art, the present invention provides a portable fire-fighting foam gun, which has the following advantages:

[0016] 1. This portable fire foam gun allows the water outlet pipe to detach from the gun body by rotating it. At this point, the locking block can be inserted into the fixing block, and the locking plate pops out and engages with the locking groove, allowing the locking plate to fix the locking block and secure the water outlet pipe to the gun body. This reduces the length of the foam gun, making it more convenient to carry. It also prevents the water outlet pipe from being dislodged by vibration during transportation, thus preventing the detached water outlet pipe from being lost. During installation, the pull plate can be pulled to move the pull rod and drive the locking plate away from the locking block, allowing the water outlet pipe to be easily connected to the gun body.

[0017] 2. This portable fire-fighting foam gun has threaded sleeves and threaded grooves respectively set on the arc-shaped outer wall of the water outlet pipe and the arc-shaped outer wall of the gun body, so that the gap between the water outlet pipe and the gun body can be blocked, preventing water leakage when the foam gun is connected, and making the connection of the foam gun more stable.

The connecting assembly 7 includes a threaded sleeve 71, a threaded groove 72, an insert block 73, a fixing block 74, a retaining block 75, a locking plate 76, a spring 77, a pull rod 78, and a pull plate 79.

[0024] In one embodiment of this utility model, a threaded sleeve 71 is fixedly connected to the outer wall of the water outlet pipe 4, a threaded groove 72 is provided on the outer wall of the gun body 1, and an insert block 73 is fixedly connected to the lower outer wall of the water outlet pipe 4.

[0025] In one embodiment of the present invention, the fixing block 74 is fixedly connected to the outer wall of the gun body 1, the outer wall of the insert block 73 is fixedly connected to the locking block 75, the locking block 75 penetrates the outer wall of the fixing block 74 and is slidably connected to the inner wall of the fixing block 74, and the inner wall of the fixing block 74 is slidably connected to the locking plate 76, the locking plate 76 penetrates the outer wall of the locking block 75.

[0026] In one embodiment of this utility model, a threaded sleeve 71 is fixedly connected to the outer wall of the water outlet pipe 4, a threaded groove 72 is provided on the outer wall of the gun body 1, and an insert block 73 is fixedly connected to the lower outer wall of the water outlet pipe 4.

[0027] In addition, the outer wall of the fixing block 74 is provided with a through slot that matches the size of the locking block 75. The locking block 75 is slidably connected to the inner wall of the slot, so that the water outlet pipe 4 that is separated from the gun body 1 can be fixed by inserting the locking block 75 into the slot, so that the position of the water outlet pipe 4 can be fixed and the separated water outlet pipe 4 can be prevented from being lost.

[0028] In an embodiment of this utility model, the outer wall of the card block 75 is provided with a locking groove that matches the locking plate 76. The locking plate 76 penetrates the inner wall of the card groove and engages with the locking groove, so that when the card block 75 is inserted into the card groove, the locking plate 76 can be inserted into the locking groove to fix the card block 75, so that the card block 75 is kept in the fixing block 74 and prevents the water outlet pipe 4 from being dislodged due to vibration during transportation.

[0029] In this embodiment of the utility model, the end of the locking block 75 away from the insertion block 73 has an inclined surface, and the end of the locking plate 76 near the locking block 75 has an inclined surface with the same slope as the inclined surface of the insertion block 73. The inclined surface on the locking plate 76 fits with the inclined surface on the locking block 75. When the locking block 75 is directly inserted into the slot, the inclined surface of the locking block 75 will push the inclined surface on the locking plate 76, so that the locking plate 76 can push the spring 77 to retract. When the locking slot is facing the locking plate 76, the locking plate 76 pops out and engages with the locking slot, so that the locking plate 76 can fix the locking block 75, making the water outlet pipe 4 more secure.

[0030] In this embodiment of the utility model, the end of the spring 77 away from the locking plate 76 is fixedly connected to the inner wall of the fixing block 74, and the spring 77 is sleeved on the outer wall of the pull rod 78. When the pull plate 79 is pulled, the pull rod 78 can drive the locking plate 76 to compress the spring 77. At this time, the locking plate 76 leaves the locking groove on the locking block 75, so that the locking block 75 can be separated from the fixing block 74, thereby allowing the water outlet pipe 4 to be released from fixation and connected to the gun body 1.

[0031] In this embodiment of the utility model, a fixing ring is fixedly connected to the outer wall of the gun body 1. The outer wall of the fixing ring is provided with a threaded groove 72.

The threaded sleeve 71 and the threaded groove 72 are respectively set on the arc-shaped outer wall of the water outlet pipe 4 and the arc-shaped outer wall of the gun body 1 so that the gap between the water outlet pipe 4 and the gun body 1 can be blocked to prevent the foam gun from leaking water when connected.

[0032] In this embodiment of the utility model, the opening diameter of the retaining ring 6 is the same as the diameter of the handle 5. The retaining ring 6 is engaged with the outer wall of the handle 5, so that when the water pipe 4 is fixed, one end of the water pipe 4 is fixed to the gun body 1 and the other end of the water pipe 4 is fixed to the handle 5, so that both ends of the water pipe 4 can be fixed, making the fixing of the water pipe 4 more stable.

[0033] In this invention, when the foam gun needs to be carried, the water outlet pipe 4 can be rotated to detach it from the gun body 1. At this time, the locking block 75 can be directly inserted into the fixing block 74. The locking block 75 pushes the locking plate 76 to retract. When the locking groove is aligned with the locking plate 76, the locking plate 76 pops out and engages with the locking groove, thus fixing the locking block 75 and securing the water outlet pipe 4 to the gun body 1. This reduces the length of the foam gun, making it more convenient to carry. This also prevents the water outlet pipe 4 from being dislodged by vibration during transportation, thus preventing the loss of the separated water outlet pipe 4. During installation, the pull plate 79 can be pulled to make the pull rod 78 drive the locking plate 76 away from the locking block 75. At this time, the water outlet pipe 4 can be released from the fixation and connected to the gun body 1. During connection, the threaded sleeve 71 and the threaded groove 72 are respectively set on the arc-shaped outer wall of the water outlet pipe 4 and the arc-shaped outer wall of the gun body 1, so that the gap between the water outlet pipe 4 and the gun body 1 can be blocked, preventing the foam gun from leaking water during connection.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
