Description
Technical Field
The invention relates to an escape window opening and closing force measuring tool and an escape window opening and closing force measuring device.
Background
The accident frequently occurs, and there are fire hazards caused by artificial internal fire and Wen Ziran high, and accidents such as collision, turning over, sinking into water, and even terrorist hijacking caused by various reasons. If the personnel in the car cannot escape from the carriage in time or cannot be rescued from the outside, the personnel often cause fatal hazard. Therefore, the quick, smooth and convenient escape window of the vehicle is very important. In the prior art, escape windows of various buses, buses and the like are mostly designed as fully-closed windows, particularly more and more buses adopt LNG as automobile power fuel, and if a fire accident occurs, the circuit system of an automatic door of the bus is extremely easy to damage, so that the door is difficult to open or even cannot open in a short time, and the escape difficulty is further increased. Therefore, in the prior art, an escape window arranged on a vehicle roof appears, and when the escape window is opened upwards by force of personnel in the vehicle, the personnel in the vehicle escapes through the escape window.
Such escape window in the prior art, for example, a top wind window is disclosed in the specification of Chinese patent application publication No. CN204095473U, which is actually equivalent to the escape window, and comprises a top cover and an inner cover, wherein a push-pull device and an opening device are respectively arranged at the front end and the rear end of the top cover, a rain shield and a rain shield ring are arranged at the upper part of the top cover, a buckle structure is arranged at the middle part of the inner cover, an inner opening device is arranged at one end of the inner cover, and an outer opening device is arranged at one end of the top cover. The national standard GB/T2334-2009 requires that the safety roof window be opened and closed flexibly under normal use conditions. The time for manually opening the emergency exit is not more than 5s, the opening and closing force when the safety roof window is opened to a ventilation state is not more than 196N, and the opening and closing force when the safety roof window is opened to the emergency exit state is not more than 50N. Therefore, the opening force of the escape window of the passenger car is in a moderate state, when the opening force of the escape window is too large, personnel in the passenger car are difficult to open, escape is not facilitated, and when the opening force of the escape window is too small, the escape window is easy to automatically pop open when the passenger car walks on a steep-lying road section, so that the tightness of the escape window is poor. The escape windows of the passenger cars are various in specification, and currently, no measuring tool for measuring the opening and closing forces of the escape windows with various specifications exists.

Embodiments of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 4, a specific embodiment of the escape window opening and closing force measuring tool of the present invention includes a transverse plate 2 and pull arms 1 located at two ends of the transverse plate in a length direction, the transverse plate 2 has a long strip structure, two connecting holes 21 penetrating through the thickness direction of the transverse plate 2 are formed in the long strip transverse plate 2, and the aperture of the connecting holes 21 in the embodiment is 8.5mm, however, in other embodiments, the aperture of the connecting holes 21 may be arbitrarily set according to needs.
The pull arm 1 is of an L-shaped plate-shaped structure, long holes 12 extending along the length direction of the transverse plate 2 are formed in the horizontal edge of the L-shaped plate, and the long holes 12 are through holes. The upper end of the pull arm 1 is provided with a bending structure, the bending structure forms a hook 11 hooked with the handle 31 on the escape window 3, and the upper surface and the lower surface of the hook 11 are both planes, so that the hook is firmly connected with the handle 31 on the escape window. It can be seen that the pull arm 1 is integrally formed with the hook 11 in this embodiment, and in other embodiments, the hook 11 may be separately formed from the pull arm 1, that is, the pull arm 1 is L-shaped, the horizontal edge of the L-shaped pull arm 1 is provided with a long hole 12, the end of the vertical portion of the L-shaped pull arm 1 is connected with the hook 11, and the hook 11 and the pull arm 1 may be connected by welding, riveting, or the like.
The cross plate 2 has a bearing structure for supporting the pressure sensor between the positions where the two tie arms 1 are connected, the bearing structure being a supporting plane.
When the escape window opening and closing force measuring tool is assembled, the long holes 12 on the two pull arms 1 are opposite to the connecting holes 21 on the transverse plate 2, fastening bolts are penetrated into the connecting holes 21 of the transverse plate 2 and the long holes 12 of the pull arms 1, and the two pull arms 1 are respectively fixedly connected with the transverse plate 2 through the fastening bolts.
Referring to fig. 4, when the tool for measuring the opening and closing force of the escape window of the present invention measures the closing force of the escape window, the two pull arms 1 can move along the length direction of the transverse plate 2 through the long holes 12, for the escape windows with different widths, the two pull arms 1 can be hooked on the handles 31 at the two ends of the escape window 3 along the width direction by adjusting the distance between the two pull arms, then the pressure sensor is placed on the transverse plate 2, the pressure sensor and the transverse plate 2 are held by hands, and the opening and closing force of the escape window can be measured by pulling the escape window downwards with force.
When the escape window opening and closing force measuring tool disclosed by the invention is used for measuring the opening force of the escape window, the pull arm only needs to have an action plane with a proper size with the escape window, and the pull arm is irrelevant to the position of the buckle. In order to facilitate measurement, an escape window opening force measuring point is set at a plane position where the intersection point of the connecting line of the buckle and the symmetry axis of the escape window is located.
The escape window has three use states, namely a closed state (the escape window is in a completely closed state), a single open state (the escape window is in a single ventilation state) and an emergency exit state. When the escape window is in a closed state, the pressure sensor is matched with the escape window opening and closing force measuring tool to measure the required thrust applied by the escape window from the closed state to the single-open state, and the measurement is repeated for three times, so that an average value is obtained. When the escape window is in a single-open state, the opening and closing force measuring tool of the escape window is used for measuring the required pulling force when the escape window is pulled to a closed state at the front end and the rear end of the escape window respectively in cooperation with the pressure sensor, and the pulling force is tested for three times respectively to obtain an average value. When the escape window is in a double-opening state, the pressure sensor is matched with the escape window opening and closing force measuring tool to measure the required thrust when the escape window is pushed to the maximum opening state, the measurement is repeated for three times, and the average value is obtained.
