DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] In order to solve the technical problem of how to reduce the external space occupied by the chip removal trolley while ensuring that the chip removal trolley has sufficient internal space, the utility model provides a retractable chip removal trolley, which can expand its internal space when dragging chips and reduce its internal space when storing the retractable chip removal trolley, thereby reducing the external space it occupies.

[0025] It should be noted that the retractable chip removal trolley of the present invention is used for but not limited to the field of towing trolleys, etc. For the sake of convenience, in the present invention, only the application of the retractable chip removal trolley in the field of towing trolleys is used as an example for explanation, and the principle of the retractable chip removal trolley applied to other types of equipment is essentially the same as the principle applied to the field of towing trolleys, so they will not be described one by one here.

[0026] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a retractable chip removal trolley according to one embodiment of the present invention. The retractable chip removal trolley includes a body assembly 100 and a limiting assembly 200. The body assembly 100 includes a first body 110 and a second body 120. The second body 120 is slidably mounted on the first body 110. The second body 120 and the first body 110 together form a receiving space. The size of the receiving space can be adjusted by changing the relative position of the second body 120 and the first body 110. The limiting assembly 200 is mounted on the first body 110 and has a first state in which it is connected to the second body 120 to limit the movement of the second body 120 relative to the first body 110, and a second state in which it is detached from the second body 120 to allow the second body 120 to move relative to the first body 110.

[0027] In this embodiment, the limiting assembly 200 is first adjusted from the second state to the first state, thereby fixing the relative position of the first car body 110 and the second car body 120. At this time, the storage space can be used to hold debris, and the above-mentioned retractable chip removal trolley can be used to haul the debris. When more debris needs to be hauled, the relative position of the first car body 110 and the second car body 120 can be adjusted, thereby expanding the storage space to hold more debris. When the retractable chip removal trolley needs to be stored, the relative position of the first car body 110 and the second car body 120 can be adjusted, thereby reducing the external space occupied by the first car body 110 and the second car body 120, saving the space occupied by the retractable chip removal trolley.

[0028] In some embodiments, the first body 110 is provided with a first connecting hole (not shown in the figure), the second body 120 is provided with a plurality of second connecting holes 121, and the limiting assembly 200 includes a limiting pin 230. When the limiting assembly 200 is in the first state, the limiting pin 230 sequentially passes through the first connecting hole (not shown in the figure) and any second connecting hole 121.

[0029] In this embodiment, when the relative position of the first vehicle body 110 and the second vehicle body 120 needs to be fixed, a stop pin 230 can be used to sequentially penetrate the first connection hole (not shown) and any second connection hole 121. This can fix the relative position of the first vehicle body 110 and the second vehicle body 120. When the relative position of the first vehicle body 110 and the second vehicle body 120 needs to be adjusted, the stop pin 230 can be disengaged from the second connection hole 121.

[0030] In some embodiments, the limiting assembly 200 further includes a mounting seat 210 and a spring 220. The mounting seat 210 is mounted on the first vehicle body 110. One end of the spring 220 is connected to the limiting pin 230, and the other end thereof is connected to the mounting seat 210. The spring 220 has an elastic force that causes the limiting pin 230 to move into the second connecting hole 121.

[0031] In this embodiment, when it is necessary to drag the limit pin 230 out of the second connecting hole 121, the elastic force of the spring 220 will be overcome. When the operator stops dragging the limit pin 230, since the spring 220 has the elastic force to move the limit pin 230 into the second connecting hole 121, under the action of the elastic force of the spring 220, the limit pin 230 will be inserted into the second connecting hole 121.

[0032] In some embodiments, the mounting seat 210 defines a mounting hole 211 , and the limiting pin 230 is movably disposed in the mounting hole 211 .

[0033] In this embodiment, since the limiting pin 230 is movably disposed in the mounting hole 211 , the limiting pin 230 can slide relative to the mounting seat 210 .

[0034] In some embodiments, the limiting pin 230 has a protrusion 231, and the mounting hole 211 has a notch around its periphery, so that the protrusion 231 can only pass through the mounting hole 211 through the notch.

[0035] In the present embodiment, when the limiting pin 230 is disengaged from the second connecting hole 121, the protrusion 231 can only pass through the mounting hole 211 through the notch, and then the limiting pin 230 is rotated, so that the protrusion 231 can be prevented from passing through the mounting hole 211, and the limiting pin 230 is prevented from being reinserted into the second connecting hole 121. When it is necessary to fix the relative positions of the first vehicle body 110 and the second vehicle body 120 again, the limiting pin 230 can be rotated so that the protrusion 231 can pass through the mounting hole 211 again, and the limiting pin 230 is reinserted into the second connecting hole 121, thereby finally fixing the relative positions of the first vehicle body 110 and the second vehicle body 120.

[0036] On the basis of the above-mentioned embodiments, in some embodiments, the limiting pin 230 has a knob 232 at the end away from the second vehicle body 120.

[0037] In the present embodiment, the operator can rotate the limiting pin 230 through the knob 232.

[0038] In some embodiments, a guide groove is formed in the first vehicle body 110, and a guide rail 122 is formed on the outer wall of the second vehicle body 120, and the guide rail 122 is movably inserted into the guide groove, so that the second vehicle body 120 slides relative to the first vehicle body 110.

[0039] In the present embodiment, since the guide rail 122 is movably inserted into the guide groove, the second vehicle body 120 has a stable sliding track relative to the first vehicle body 110.

[0040] In some embodiments, the vehicle body assembly 100 further has a plurality of guide wheels 130, which are rotatably installed on the first vehicle body 110 or the second vehicle body 120.

[0041] In some embodiments, the vehicle body assembly 100 further has a towing handle 140, which is connected to the first vehicle body 110.

[0042] In the present embodiment, the operator can pull the towing handle 140 to move the telescopic chip removal trolley.

[0043] On the basis of the above-mentioned embodiments, in some embodiments, one end of the towing handle 140 is hingedly connected to the first vehicle body 110, so that the towing handle 140 can rotate relative to the first vehicle body 110.

[0044] In this embodiment, since the traction handle 140 can rotate relative to the first vehicle body 110, the inclination angle of the traction handle 140 changes, thereby improving the comfort of the operator when dragging the retractable chip removal trolley.

[0045] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0046] The limit pin 230 can be used to sequentially pass through the first connecting hole (not shown in the figure) and any second connecting hole 121. This allows the relative positions of the first car body 110 and the second car body 120 to be fixed. At this time, the storage space can be used to hold debris, and the above-mentioned retractable chip removal trolley can be used to haul the debris. When more debris needs to be hauled, when the relative positions of the first car body 110 and the second car body 120 need to be adjusted, the limit pin 230 can be disengaged from the second connecting hole 121. The relative positions of the first car body 110 and the second car body 120 can then be adjusted, thereby expanding the storage space and accommodating more debris. When the retractable chip removal trolley needs to be stored, the relative positions of the first car body 110 and the second car body 120 can also be adjusted, thereby reducing the external space occupied by the first car body 110 and the second car body 120, saving the space occupied by the retractable chip removal trolley.

[0047] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
