Example (b):

referring to fig. 1-3, the present invention provides a technical solution: a distance measuring protective structure for an automobile chassis comprises an upper mounting plate 1, a sleeve 2 and a scale 5, wherein the sleeve 2 and the scale 5 are connected to the lower side of the upper mounting plate 1 through screws, a movable rod 3 is inserted into the lower side of an inner cavity of the sleeve 2, an adjusting groove 6 is formed in the outer wall of the sleeve 2 along the axis direction of the sleeve 2, a press type switch assembly 7 is arranged in the adjusting groove 6, an alarm 8 and a storage battery 9 are arranged on the side wall of the sleeve 2, the press type switch assembly 7 comprises a sliding block 71 transversely clamped in the adjusting groove 6, a screw 72 is arranged at one end, located outside the sleeve 2, of the sliding block 71, a friction pad 73 and a clamping spring 74 are sleeved on the outer wall of the screw 72, a fastening nut 75 is screwed at the outer end of the outer wall of the screw 72, a mounting plate 76 is arranged at one, the alarm 8 and the storage battery 9 are connected in series through a lead.

The bottom of the movable rod 3 is provided with a roller 4, the roller 4 is a universal roller, and the movement of the movable rod 3 on the ground is smooth through the arrangement of the roller 4, so that the measurement effect on different positions is convenient;

the inner cavity of the sleeve 2 is provided with a supporting spring 10, the upper end and the lower end of the supporting spring 10 are respectively supported on the bottom of the upper mounting plate 1 and the upper surface of the movable rod 3, and the supporting spring 10 is supported between the mounting plate 1 and the movable rod 3, so that the movable rod 3 can be tensioned, and the movable rod 3 is always kept in contact with the ground;

the cross section of the sliding block 71 is rectangular, so that the sliding block 71 is prevented from rotating relative to the sleeve 2, and the contact of the press-contact switch 77 always faces to the top end of the movable rod;

the transverse width of the sliding block 71 is smaller than the thickness of the side wall of the sleeve 2, the friction pad 73 is clamped on the outer wall of the sleeve 2 through the elastic action of the clamping spring 74, the sliding block 71 is positioned through friction force, when the movable rod 3 moves upwards to touch the pressure contact switch 77, the movable rod 3 continuously moves upwards to drive the mounting plate 76 to move upwards, and the design mode that the transverse width of the sliding block 71 is smaller than the thickness of the side wall of the sleeve 2 cannot influence the movement of the sliding block in the adjusting groove 6.

The working principle is as follows: when the height of a position, such as an oil tank on the lower side of an automobile chassis, from the ground is required to be measured, the upper mounting plate 1 is fixedly mounted at the bottom of the position, which is required to be measured, of the chassis through a screw, at the moment, the automobile is required to be unloaded, the sliding block 71 slides in the adjusting groove 6 to an alert position (the alert position is a minimum allowable value from the ground, if the measured distance value is smaller than the minimum allowable value, the chassis is considered to be too small from the ground), the fastening nut 75 is screwed with the screw 72, so that the clamping spring 74 is compressed, the friction pad 73 is tightly attached to the outer wall of the sleeve 2 under the elastic force of the clamping spring 74, and the pressing type switch assembly 7 is kept fixed on the adjusting groove 6;

when the movable rod 3 rises to the position of the press-contact switch 77 relative to the sleeve 2, the press-contact switch 77 is closed through pressure (the press-contact switch 77 is set to be in a normally open state and is closed after being subjected to pressure, conductor contacts are separated again under the action of an internal elastic piece after the pressure is removed), a circuit where the alarm 8 is located is conducted, the alarm function is started, the alarm 8 adopts a warning lamp or a loud-speaker alarm (the alarm 8 alarms that the height of the full-load chassis is lower than the warning position and the alarm 8 does not alarm as normal), the press-type switch assembly 7 is pushed to overcome the friction force between the friction pad 73 and the side wall of the sleeve 2 to rise under the continuous upward moving action of the movable rod 3 to indicate that the movable rod 3 stops rising, the position H of the press-type switch assembly 7 away from the upper mounting plate 1 is measured through the scale 5, the height of the measuring position from the ground can be obtained, namely H + the axial length of the movable rod 3 + the height of the roller 4.

Having shown and described the basic principles and principal features of the invention and advantages thereof, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof; the present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
