A pull rod 140 is installed in either the first box section 110 or the second box section 120 of the box 100.

[0038] like Figure 2 and Figure 4 As shown, the lock frame 200 includes a first lock frame portion 210 and a second lock frame portion 220. The first lock frame portion 210 and the second lock frame portion 220 are generally rectangular frames. The first lock frame portion 210 and the second lock frame portion 220 are movably connected. Specifically, the first lock frame portion 210 and the second lock frame portion 220 are movably connected by two hinges 230. That is, the first ends of the two hinges 230 are fixedly connected to the outer side of the first lock frame portion 210 by screws, and the second ends of the two hinges 230 are fixedly connected to the outer side of the second lock frame portion 220 by screws, so that the first lock frame portion 210 rotates relative to the second lock frame portion 220 about the central axis of the two hinges 230.

[0039] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first lock frame portion 210 and the second lock frame portion 220 of the lock frame 200 are fixedly connected to the first housing portion 110 and the second housing portion 120, respectively. Specifically, the first lock frame portion 210 includes a first mounting position 211, which is a groove, and a portion of the first housing portion 110 is located within the first mounting position 211 for mounting the first housing portion 110.

[0040] like Figures 1-4As shown, the first locking frame portion 210 further includes a first fixing component 212, which is used to fix the first housing portion 110; the second locking frame portion 220 further includes a second fixing component 222, which is used to fix the second housing portion 120; specifically, the first fixing component 212 consists of multiple screws and multiple nuts, with the multiple screws sequentially penetrating the first housing portion 110 and the first locking frame portion 210 and extending into the housing 100 to engage with the corresponding nuts, thereby fixing the first housing portion 110 to the first locking frame portion 210. Currently, the first fixing component 212 can also be glue, and the first housing portion 110 and the first locking frame portion 210 can be fixed together. The first locking frame 210 is fixed with glue. Alternatively, the first fixing component 212 can be a combination of the two fixing methods mentioned above. Similarly, the second fixing component 222 consists of multiple screws and multiple nuts. The multiple screws pass through the second housing 120 and the second locking frame 220 in sequence and extend into the housing 100 to engage with the corresponding nuts, thereby fixing the second housing 120 and the second locking frame 220. Currently, the second fixing component 222 can also be glue, and the second housing 120 and the second locking frame 220 are fixed with glue. Alternatively, the second fixing component 222 can be a combination of the two fixing methods mentioned above.

[0041] like Figure 5 and Figure 6 As shown, the support portion 300 is used to support the lock frame 200 so that the lock frame 200 remains in an open posture. Specifically, the support portion 300 includes a first support frame 310 and a second support frame 320. The first support frame 310 and the second support frame 320 are generally rectangular frames. The first support frame 310 and the second support frame 320 can be steel wire frames. The first support frame 310 is used to support the first lock frame portion 210 of the lock frame 200 so that the first lock frame portion 210 remains in an open posture and avoids the first lock frame portion 210 from being severely deformed by force. Similarly, the second support frame 320 is used to support the second lock frame portion 220 of the lock frame 200 so that the second lock frame portion 220 remains in an open posture and avoids the second lock frame portion 220 from being severely deformed by force.

[0042] In one alternative implementation, such as Figure 5 and Figure 6 As shown, the first lock frame portion 210 includes a third mounting position 213 for mounting the first support frame 310; the first lock frame portion includes a fourth mounting position 223 for mounting the second support frame 320. Specifically, the third mounting position 213 is an L-shaped groove, and the first support frame 310 is entirely located within the L-shaped groove for mounting the first support frame 310; similarly, the fourth mounting position 223 is an L-shaped groove, and the second support frame 320 is entirely located within the L-shaped groove for mounting the second support frame 320.

[0043] like Figure 5 and Figure 6 As shown, the first lock frame portion 210 further includes a third fixing component 214, which is used to fix the first support frame 310; the second lock frame portion 220 further includes a fourth fixing component 224, which is used to fix the second support frame 320; specifically, the third fixing component 214 includes a first mating part 2141 and a first fixing part (not shown in the figure). The first mating part 2141 is fixed to the first lock frame portion 210, and the first fixing part cooperates with the first mating part 2141 to fix the first support frame 310 to the first lock frame portion 210. The first mating part 2141 consists of multiple screw seats, which together with the L-shaped groove form a recess. The first fixing part consists of multiple screws, which are screwed into the corresponding screw seats, and the screw heads of the multiple screws are used to fix the first support frame 310. A support frame 310 is positioned to ensure that the first support frame 310 is located within the third mounting position 213 of the first locking frame portion 210. Similarly, the fourth fixing component 224 includes a second mating member 2241 and a second fixing member (not shown in the figure). The second mating member 2241 is fixed to the second locking frame portion 220, and the second fixing member cooperates with the second mating member 2241 to fix the second support frame 320 to the second locking frame portion 220. The second mating member 2241 consists of multiple screw seats, which together with the L-shaped groove form a recess. The second fixing member consists of multiple screws, which are screwed into the corresponding screw seats. The screw heads of the multiple screws limit the second support frame 320 to ensure that the second support frame 320 is located within the fourth mounting position 223 of the second locking frame portion 220.

[0044] like Figure 1 and Figure 3As shown, a locking assembly 240 is installed on the first locking frame portion 210 and the second locking frame portion 220. The locking assembly 240 is used to lock the first locking frame portion 210 and the second locking frame portion 220. Specifically, there are two locking assemblies 240, which are spaced apart. The portions of the first locking frame portion 210 and the second locking frame portion 220 corresponding to the mounting portions of the locking assemblies 240 are recessed inward to form mounting positions. The locking assemblies 240 are installed in the mounting positions. At this time, since the length of the locking assembly 240 is greater than the height of the first locking frame portion 210 and the second locking frame portion 220, the two ends of the locking assembly 240 face the first housing portion 110 and the second housing portion 120, respectively. The first housing portion 110 includes a first positioning groove 111, which is used to position the first end of the locking assembly 240. The second housing portion 120 includes a second positioning groove 121, which is used to position the second end of the locking assembly 240. When it is necessary to open the housing 100, the locking assembly 240 is used to unlock it, and the first locking frame 210 and the second locking frame 220 can rotate around the central axis of the hinge 230. At this time, the first housing 110 and the second housing 120 are opened as the first locking frame 210 and the second locking frame 220 rotate. Conversely, when it is necessary to close the housing 100, the locking assembly 240 locks the first locking frame 210 and the second locking frame 220, and the first locking frame 210 and the second locking frame 220 cannot rotate, and the housing 100 is closed.

[0045] like Figure 5 and Figure 6 As shown, the first locking frame portion 210 includes a limiting groove 215, and the second locking frame portion 220 includes a limiting protrusion 225. The limiting groove 215 and the limiting protrusion 225 cooperate to limit the first locking frame portion 210 to the second locking frame portion 220, so as to prevent the first locking frame portion 210 from being misaligned relative to the second locking frame portion 220 when the box 100 is closed.

[0046] like Figures 1-4 As shown, a handle portion 250 is also installed on the first lock frame portion 210 or the second lock frame portion 220. Specifically, there are two handle portions 250. The first handle portion 250 is located on the top of the first lock frame portion 210 or the second lock frame portion 220, and the second handle portion 250 is located between the two lock components 240. The handle portion 250 can be installed by fixing it to the first lock frame portion 210 or the second lock frame portion 220 with screws. Alternatively, the handle portion 250 can be integrally formed with the first lock frame portion 210 or the second lock frame portion 220.

[0047] The trolley case with the sunken injection-molded lock frame in this embodiment supports the lock frame 200 through the support part 300, so that the lock frame 200 is kept in an open posture, which can effectively prevent the lock frame 200 from deforming.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
