Abstract
Description
Technical Field
[0001] The utility model relates to the field of firefighting and rescue, in particular to a small cart used for firefighting and rescue. Background Art
[0002] With the development of society, high-rise buildings are everywhere. Therefore, when a fire occurs and elevators are no longer in use, fire rescue often uses stretchers or manpower to rescue the elderly, the weak, the sick and the disabled to escape from the fire stairs. The use of a stretcher not only requires the cooperation of two people, affecting the rescue speed, but the corners of the stairs are more likely to be unable to maneuver due to the narrow corridors, and the use of manpower rescue is laborious and affects the speed. Summary of the invention
[0003] One purpose of the utility model is to provide: a small cart for fire rescue, which solves the technical problems in the prior art that various factors such as stretchers and manpower lead to slow rescue speed, waste of rescue personnel and labor.
[0004] The technical solution of the utility model is achieved as follows: a small cart for fire rescue, including a base frame, a rotatable roller connected to the front end of the base frame, a connecting rod hinged to the front end of the base frame, a folding handle rod hinged to the rear end of the base frame, the folding handle rod including a forearm hinged to the base frame and a rear arm hinged to the forearm, a clamping piece for fixing the forearm and the rear arm is provided at the connection between the forearm and the rear arm, and the rear end of the connecting rod is hinged to the rear arm of the folding handle rod.
[0005] Furthermore, a slide plate is installed at the bottom of the front end of the chassis, and a brake rubber strip is installed at the bottom of the rear end of the chassis.
[0006] Furthermore, a supporting cloth is installed on the connecting rod to support the weight of a human body.
[0007] Furthermore, the clamping member includes a main body, a spring pin is installed in the main body, a handle is installed at one end of the spring pin, a clamping head engaged with the main body is installed on the rear arm, and a clamping hole cooperating with the spring pin is provided on the clamping head.
[0008] Furthermore, a handle is extended from the tail of the rear arm.
[0009] Furthermore, a chassis handle is provided at the rear end of the chassis.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model arranges a pulley at the front end of the base frame, and hinges a folding handle rod at the rear end of the base frame. The folding handle rod folds the front arm and the rear arm of the folding handle rod through a clamping piece. The folded volume is small, and after opening, it can be moved quickly through the pulley and the skateboard, which is labor-saving and more convenient. The vehicle speed can also be controlled by the brake rubber strip, which is in line with human mechanics and there is no need to bend over. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] like Figures 1 to 5 As shown, this embodiment provides: a small cart for fire rescue, including a base frame 1, a rotatable roller 2 is connected to the front end of the base frame 1, a connecting rod 3 is hinged to the front end of the base frame 1, and a folding handle rod 4 is hinged to the rear end of the base frame 1. The folding handle rod 4 includes a front arm 41 hinged to the base frame 1 and a rear arm 42 hinged to the front arm 41. A clamping member 43 for fixing the front arm 41 and the rear arm 42 is provided at the connection between the front arm 41 and the rear arm 42, and the rear end of the connecting rod 3 is hinged to the rear arm 42 of the folding handle rod 4. The utility model: by installing the folding handle rod 4 on the base frame 1, when the small cart is not in use, the rear arm 42 of the folding handle rod 4 is folded toward the front arm 41 through the engagement of the clamping member 43.
[0018] Furthermore, a slide plate 11 is installed at the bottom of the front end of the chassis 1, and a brake rubber strip 12 is installed at the bottom of the rear end of the chassis 1. After the slide plate 11 is installed, the front end surface of the chassis 1 is smooth, the friction is small, and the pushing resistance when going down the stairs is reduced. After the brake rubber strip 12 is installed at the rear end of the chassis 1, it can play an anti-skid role. When deceleration is required, the brake rubber strip is lowered to contact the step to form a braking force.
[0019] Furthermore, a supporting cloth 31 is installed on the connecting rod 3 to support the weight of a human body.
[0020] Furthermore, the clamping member 43 includes a main body 431, a spring pin 432 is installed in the main body 431, a handle 433 is installed at one end of the spring pin 432, a clamping head 434 engaged with the main body 431 is installed on the rear arm 42, and a clamping hole 435 matched with the spring pin 432 is provided on the clamping head 434. After pressing the handle 433, the spring pin 432 shrinks into the main body 431, and the rear arm 42 is pushed toward the front arm 41, so that the folding handle rod 4 can be folded up. When it is needed, the clamping hole 435 can be engaged with the spring pin 432 by simply pulling the rear arm 42 toward the rear end of the base frame 1.
[0021] Furthermore, a handle 421 extends from the rear end of the rear arm 42. When used in the state of going down stairs, since the pulley 2 and the slide 11 are installed at the front end of the base frame 1, the pulley 22 and the slide 11 can be used to quickly go down the stairs, which is more labor-saving. The handle 421 is held to lower the trolley until the brake rubber strip 12 contacts the step, which plays a braking role, preventing slipping and saving labor.
[0022] Further, the rear end of the chassis 1 is also provided with a chassis handle 13. When used on a flat ground, the handle 13 of the chassis 1 can be held to lift the trolley, and the roller 2 at the front end of the chassis 1 can be pushed forward, which can save effort and move quickly, and is more convenient.
[0023] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are included in the protection scope of the present invention.
