Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and fig. 2, a description will now be given of a sleeper box of a heavy truck with a widening function according to the present invention. The heavy truck sleeper box with widen function includes: sleeping berth case body 1, upset backup pad 2, slider 3 and connecting rod 4. A sliding groove 101 is longitudinally arranged on one side of the sleeping berth box body 1, and a first clamping groove 102 is arranged on the upper part of the sliding groove 101; the overturning supporting plate 2 is rotatably arranged on one side of the sleeping berth box body 1 close to the sliding chute 101; the sliding block 3 is arranged in the sliding groove 101 in a sliding mode, and a top pin 5 in clamping fit with the first clamping groove 102 is arranged on the sliding block 3; the two ends of the connecting rod 4 are respectively connected with the overturning supporting plate 2 and the sliding block 3 in a rotating way.

The utility model provides a pair of heavy truck sleeping berth case with widen function, compared with the prior art, vertically be equipped with spout 101 along one side of sleeping berth case body 1, be equipped with first draw-in groove 102 on the upper portion of

spout

101, 2 rotation of upset backup pad are installed in one side that is close to spout 101 on sleeping berth case body 1, slider 3 slides in spout 101 to be equipped with on slider 3 with first draw-in groove 102 joint complex knock pin 5, be connected through connecting rod 4 between upset backup pad 2 and the slider 3. When the sleeper box needs to be widened, the slide block 3 is driven to move along the vertical direction, the turnover supporting plate 2 is driven to rotate through the connecting rod 4 to be flush with the top surface of the sleeper box body 1, and the slide block 3 is relatively fixed with the sleeper box body 1 in the sliding groove 101 by means of clamping and matching of the top pin 5 and the first clamping groove 102, so that the sleeper box is widened; when not needing to use the sleeping berth case, thereby preceding movable slide block 3 removes the spacing between slide block 3 and the sleeping berth case body 1, then rotates upset backup pad 2 to being in and packs up the state to reduced the shared space of sleeping berth case, promoted space utilization. This joint structure easy operation for upset backup pad 2 is more convenient when opening or packing up.

In this embodiment, the connecting rod 4 is hinged to the turnover supporting plate 2 and the sliding block 3. The spout 101 is seted up on the lateral wall of sleeping berth case body 1 along vertical direction, and when upset backup pad 2 rotated to being in operating condition (upset backup pad 2 is in the horizontality promptly), the top surface of upset backup pad 2 and the top surface parallel and level of sleeping berth case body 1, connecting rod 4 played the supporting role to upset backup pad 2. The number of connecting rods 4 can adopt one, and is located the center of upset backup pad 2, also can evenly arrange many, and every connecting rod 4 corresponds a slider 3 to improve the support intensity to upset backup pad 2. When needs are packed up upset backup pad 2, will overturn backup pad 2 and rotate 90 downwards, upset backup pad 2 just laminates with the lateral wall of sleeping berth case body 1 this moment to make space utilization reach the biggest.

As a specific embodiment of the utility model provides a heavy truck sleeping berth case with widen function, please refer to fig. 2, knock pin 5 is the elasticity knock pin, is equipped with the chamber 301 that holds that is used for holding the elasticity knock pin on the slider 3.
