DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In the related art, a striking logo is hung on the surface of the integrated machine, but there is a visual blind spot during the reversing process and the integrated machine is prone to collision.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an anti-collision box inverter all-in-one machine. When it is needed, it only needs to squeeze the airbag to exhaust the air when a collision occurs, so that a whistle sounds to remind the operator.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-Figure 4 The embodiment of the present application provides an anti-collision box inverter integrated machine, including a chassis 1, a limiting sleeve 2 is fixedly installed on the inner top wall and the inner bottom wall of the chassis 1, the inner sliding connection of the limiting sleeve 2 is connected with a sliding rod 3, the sliding rod 3 extends to the outside of the chassis 1, and a connecting plate 4 is fixedly installed on one end of the sliding rod 3 located on the outside of the chassis 1, an elastic airbag 5 is fixedly installed on the side of the connecting plate 4 away from the chassis 1, and a pressure plate 6 is fixedly installed on the end of the elastic airbag 5 away from the connecting plate 4, and the air inlet end and the exhaust end of the elastic airbag 5 are both connected with a one-way valve 7, wherein the one-way valve 7 at the exhaust end is connected with a whistle 8.

[0032] In some embodiments, an extrusion friction sleeve 15 is fixedly embedded inside the limiting sleeve 2, and an extrusion friction block 9 is slidably connected to the middle part of the extrusion friction sleeve 15. The extrusion friction block 9 is fixedly connected to the sliding rod 3. Through such a setting, the resistance of the sliding rod 3 when sliding can be increased, so that the elastic airbag 5 can be compressed and exhausted.

[0033] Specifically, the cross-sectional shape of the extrusion friction sleeve 15 is a "V" shape, and the shape of the extrusion friction block 9 is a trapezoid. With such an arrangement, the further the extrusion friction block 9 moves backward, the greater the friction force it is subjected to, thereby being able to offset the impact of a collision.

[0034] In some embodiments, a base 10 is provided under the chassis 1, rollers 11 are fixedly installed at the four corners of the bottom end of the base 10, and a supporting friction block 12 is fixedly installed at the bottom end of the base 10. Through such a setting, the chassis 1 can play a buffering role by sliding after a collision.

[0035] Specifically, support sleeves 13 are fixedly installed on both sides of the base 10, and ground nails 14 with breaking grooves are sleeved inside the support sleeves 13. Through such an arrangement, the position of the chassis 1 can be fixed, and the chassis 1 can still be displaced after the ground nails 14 are broken.

[0036] Specifically, the limiting sleeves 2 are divided into two groups, an upper group and an lower group, and each group of limiting sleeves 2 includes two symmetrical front and rear groups. Through such an arrangement, the connecting plate 4 can be subjected to uniform force.

[0037] Specifically, wing plates are provided on both sides of the limiting sleeve 2, and the wing plates are connected to the chassis 1 by bolts. Such an arrangement can facilitate the connection of the device.

[0038] Specifically, the cross-sectional shape of the extrusion friction sleeve 15 is "H"-shaped, and a protrusion connected to the limit sleeve is provided in the middle of the extrusion friction sleeve 15. The two extrusion friction blocks 9 are respectively located in the inclined grooves of the extrusion friction sleeve 15. Through such an arrangement, the extrusion on both sides can be symmetrically handled in a single limit sleeve 2 at the same time, thereby saving space.

[0039] When a collision occurs, due to the friction resistance between the extrusion friction block 9 and the extrusion friction sleeve 15, the elastic airbag 5 can be exhausted by squeezing the pressure plate 6, and a sound is emitted through the whistle 8 for reminder. When the collision continues, the extrusion friction block 9 can be used to squeeze the friction sleeve 15 to deform, allowing the sliding rod 3 to slide for buffering. When the collision is not paused, the ground nail 14 with the breaking groove breaks, and the chassis 1 slides as a whole for buffering.

[0040] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.
