Description

Technical Field

[0001] The utility model relates to the technical field of air outlet connecting hoses of air pumps, in particular to a connecting hose for a fire fighting air pump with anti-vibration function. Background Art

[0002] Fire trucks are essential rescue equipment for fire fighting. However, due to design defects of fire truck manufacturers: the air outlet connecting hose of the fire truck air pump is close to the engine of the fire truck. As long as the fire truck starts, the engine generates vibration, and the screw of the engine will rub against the air outlet hose of the air pump. After a long time, the hose will be worn and cracked, making the fire truck unable to be put into use (in actual use, from the factory to the fire brigade, when the fire truck travels 800 to 1000 kilometers, the hose will be worn through). Saving lives in case of fire, once a fire alarm is received and the fire truck cannot be used, the losses caused are immeasurable, which is undoubtedly a huge hidden danger to fire fighting and rescue work. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a connecting hose for a fire fighting air pump with anti-vibration function, which solves the technical problem that the existing air outlet connecting hose of the air pump is easy to contact and rub with the engine screw, resulting in easy wear and breakage of the hose.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0005] A connecting hose for a fire fighting air pump with anti-vibration function includes a fire truck engine, an engine screw and two fire truck frame fixing rods, and also includes a connecting hose body. Two fixing mechanisms are arranged on the surface of the connecting hose body.

[0006] Preferably: the connecting hose body includes a pipe body, and pipe heads are fixedly connected to both ends of the pipe body. The length of the pipe body is 80CM.

[0007] Preferably: the fixing mechanism includes a rubber sleeve, and a binding strap and a limit buckle are fixedly arranged on the surface of the rubber sleeve.

[0008] Preferably: the rubber sleeve is slidably sleeved on the surface of the pipe body.

[0009] Preferably: the pipe body is provided with a U-shaped bend, and the pipe body does not contact the fire truck engine and the engine screw.

[0010] Preferably: the binding strap and the limit buckle are adapted to each other, and the loops formed by the binding straps and the limit buckles of the two fixing mechanisms respectively sleeve the two fire truck frame fixing rods.

[0011] The utility model has the following beneficial effects:

[0012] 1. This application is provided with a pipe body with a length of 80 cm. When connecting, it bypasses the fire truck engine and the engine screw rod. At the same time, the pipe body is fixed on two fixed rods of the fire truck frame by a fixing mechanism, which can avoid the friction between the pipe body and the fire truck engine. When the fire truck engine works, it generates vibration but the pipe body does not contact the fire truck engine, which can improve the serviceability rate of the fire truck and solve the problem that the existing connecting hose body is prone to contact and friction with the engine screw rod, resulting in easy abrasion of the pipe body.

[0018] The embodiment of the present application provides a vibration-resistant connecting hose for a fire fighting air pump, which effectively solves the problem that the existing air pump outlet connecting hose is prone to contact and friction with the engine screw rod, resulting in easy abrasion of the hose.

[0019] As Figures 1-3 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing air pump outlet connecting hose is prone to contact and friction with the engine screw rod, resulting in easy abrasion of the hose. The general idea is as follows:

[0020] In view of the problems existing in the prior art, the present invention provides a vibration-resistant connecting hose for a fire fighting air pump, including a fire truck engine 1, an engine screw rod 2 and two fixed rods 3 of the fire truck frame, including a connecting hose body 4, and two fixing mechanisms 5 are arranged on the surface of the connecting hose body 4.

[0021] The connecting hose body 4 includes a pipe body 401, and pipe heads 402 are fixedly connected to both ends of the pipe body 401. The length of the pipe body 401 is 80 cm, and the longer pipe body 401 can obtain a larger movable range.

[0022] The fixing mechanism 5 includes a rubber sleeve 501. A strap 502 and a limit buckle 503 are fixedly arranged on the surface of the rubber sleeve 501. The fixing mechanism 5 fixes the connecting hose body 4 on the fixed rod 3 of the fire truck frame.

[0023] The rubber sleeve 501 is slidably sleeved on the surface of the pipe body 401. The rubber sleeve 501 can move its position according to actual needs, which is convenient for fixing.

[0024] The pipe body 401 is provided with a U-shaped bend. The pipe body 401 does not contact the fire truck engine 1 and the engine screw 2, so as to avoid friction between the pipe body 401 and the fire truck engine 1.

[0025] The strap 502 and the limit buckle 503 are adapted to each other. The loops formed by the straps 502 and the limit buckles 503 of the two fixing mechanisms 5 respectively sleeve the two fixed rods 3 of the fire truck frame.

[0026] Due to the air pump outlet steel mesh connecting hose (length 40CM) configured in the fire truck at the factory, limited by the length, it is close to the engine screw 2. Once the fire truck engine 1 starts, vibration occurs and friction occurs with the connecting hose. Just replace the steel mesh connecting hose with a connecting hose body 4 with a length of 80CM. When connecting, bypass the fire truck engine 1, and at the same time use the fixing mechanism 5 to fix the connecting hose body 4 on the fixed rod 3 of the fire truck frame, then it can avoid friction between the connecting hose body 4 and the fire truck engine 1 and improve the serviceability rate of the fire truck.

[0027] Working principle:

[0028] During the process of connecting the air pump and the air storage tank, a pipe body 401 with a length of 80 centimeters is used. In order to avoid friction between the pipe body 401 and the fire truck engine 1 during use, first of all, the pipe body 401 bypasses the fire truck engine 1 and the engine screw 2 during connection to ensure there is enough space between them. Then, in order to further ensure the stability and safety of the pipe body 401 during use, the fixing mechanism 5 is used to firmly fix the pipe body 401 on the two fixed rods 3 of the fire truck frame. In this way, even when vibration occurs during the operation of the fire truck engine 1, the pipe body 401 will not contact the fire truck engine 1, thus avoiding possible friction and damage. Through this ingenious design and installation method, we can effectively improve the serviceability rate of the fire truck, ensure its normal operation during long-term use, and thus better complete the rescue mission.

[0029] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
