The component has four members, which are respectively located at the left front, right front, left rear, and right rear of the vehicle's cargo box. The ends of the four members have inclined surfaces, wherein the inclined surfaces of the ends of the two members located at the front of the cargo box face the upper front of the vehicle, and the inclined surfaces of the ends of the two members located at the rear of the cargo box face the upper rear of the vehicle. The limiting device includes:

[0006] A base is installed inside the cargo box;

[0007] A limiting member has a first end and a second end opposite to each other. The limiting member is arranged along the length direction of the limiting device, and the first end of the limiting member is connected to the base.

[0008] A fastener is adjustablely inserted into the second end of the limiting member. The fastener is inclined along the length direction perpendicular to the limiting device. The height of the first end of the fastener is lower than the height of the second end of the fastener. The first end of the fastener is provided with a working surface, and the working surface of the fastener is connected to the inclined surface of the end of the member.

[0009] The number of limiting devices is four, including two first limiting devices and two second limiting devices. The first limiting devices and the second limiting devices are arranged in a mirror image. In the direction from the first end to the second end of the fastener of the first limiting device, the base of the first limiting device is located on the left side of the fastener of the first limiting device. In the direction from the first end to the second end of the fastener of the second limiting device, the base of the second limiting device is located on the right side of the fastener of the first limiting device.

[0010] In some embodiments, the fastener is threadedly connected to the limiting member.

[0011] In some implementations, the working surface is a sphere.

[0012] In some embodiments, the base is bolted to the bottom of the cargo box.

[0013] In some embodiments, the limiting device further includes a connector surrounding the base on both sides of the limiting device in the width direction and on the top surface of the base, and a second end of the limiting device is connected to the connector.

[0014] In some embodiments, a first protrusion is provided on the base along the top surface of the base and on the side of the base away from the fastener;

[0015] The connector has a groove on the top surface of the base and on the side of the base away from the fastener, and the first protrusion is engaged in the groove.

[0016] In some embodiments, a second protrusion is provided on the side of the base near the fastener;

[0017] The connector has a groove on the side of the base near the fastener, and the second protrusion is engaged in the groove.

[0018] In some embodiments, the connector is connected to the base by fixing bolts.

[0019] In some embodiments, the limiting device further includes a support member that passes through the base along the width direction of the limiting device. The fixed end of the support member is disposed opposite to the first end of the fastener, and the fixed end of the support member is connected to the inner side of the cargo box.

[0020] In some embodiments, the support member is bolted to the cargo box.

[0021] The embodiments of this application have at least the following beneficial effects:

[0022] The limiting device proposed in this application comprises: a first limiting device disposed at the front left of the cargo box of a vehicle, with the working surface of the fastener of the first limiting device facing the rear of the cargo box and connected to the inclined surface of the end of a component on the rocket assembly located at the front left of the cargo box; a second limiting device disposed at the front right of the cargo box, with the working surface of the fastener of the first limiting device facing the front of the cargo box and connected to the inclined surface of the end of a component on the rocket assembly located at the rear right of the cargo box; a third limiting device disposed at the front right of the cargo box, with the working surface of the fastener of the second limiting device facing the rear of the cargo box and connected to the inclined surface of the end of a component on the front right of the cargo box; and a fourth limiting device disposed at the rear left of the cargo box, with the working surface of the fastener of the second limiting device facing the front of the cargo box and connected to the inclined surface of the end of a component on the rear left of the cargo box. Furthermore, since the position of the fastener is adjustable, the working surface of the fastener can be adjusted to press against the inclined surface of the component end. This allows for the positioning and fixing of rocket components through four limiting devices installed inside the cargo box.

[0023] In addition, the above-mentioned setup mainly restricts the movement of rocket components within the vehicle cargo box along the vehicle's direction of travel. To further restrict the movement of rocket components within the vehicle cargo box along the sides of the vehicle, it is also necessary to connect the side of the base near the fastener to the components of the rocket component, thereby achieving complete horizontal positioning and fixation of the rocket component and preventing damage to the component during transportation.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments:

[0037] In this embodiment, the rocket component 300 is provided with four components 310. When the component 300 is placed inside the cargo box 200 of the vehicle, the four components 310 on the component 300 are respectively located at the left front, right front, left rear, and right rear of the cargo box 200. The ends of the four components 310 have inclined surfaces 311. The inclined surfaces of the ends of the two components 310 located at the front of the cargo box 200 face the front upper part of the vehicle, and the inclined surfaces 311 of the ends of the two components 310 located at the rear of the cargo box 200 face the rear upper part of the vehicle. There is a gap between the component 300 and the inner side of the cargo box 200. Due to the lack of a device for limiting and fixing the component 300, the component 300 may collide with the cargo box 200 of the vehicle during transportation and be damaged.

[0038] In order to limit and fix the rocket component 300 being transported on the vehicle, this application embodiment proposes a limiting device. Figures 1-4 This is a schematic diagram of the structure of a limiting device according to an embodiment of this application, combined with... Figures 1-4 The limiting device 100 includes a base 130, a limiting member 140, and a fastener 150.

[0039] In this embodiment, the base 130 is disposed inside the cargo box 200 of the vehicle transporting the rocket component 300. The limiting member 140 has a first end and a second end opposite to each other. The limiting member 140 is disposed along the length direction of the limiting device 100. The first end of the limiting member 140 is connected to the base 130. The fastener 150 is disposed adjustablely on the second end of the limiting member 140. The fastener 150 is disposed inclined along the length direction perpendicular to the limiting device 100, and the height of the first end of the fastener 150 is lower than the height of the second end of the fastener 150. The first end of the fastener 150 is provided with a working surface 151, and the working surface 151 of the fastener 150 is connected to the inclined surface 311 of the end of the component 310 of the rocket component 300. The number of limiting devices 100 is four, including two first limiting devices 110 and two second limiting devices 120. The first limiting devices 110 and the second limiting devices 120 are arranged in a mirror image. In the direction from the first end to the second end of the fastener 150 of the first limiting device 110, the base 130 of the first limiting device 110 is located on the left side of the fastener 150 of the first limiting device 110. In the direction from the first end to the second end of the fastener 150 of the second limiting device 120, the base 130 of the second limiting device 120 is located on the right side of the fastener 150 of the first limiting device 110.

[0040] Specifically, such as Figure 2 as well as Figure 5As shown, a first limiting device 110 is disposed at the left front of the cargo box 200 of the vehicle, and the working surface 151 of the fastener 150 of the first limiting device 110 faces the rear of the cargo box 200 and is connected to the inclined surface 311 at the end of the component 310 on the rocket component 300 located at the left front of the cargo box 200. Another first limiting device 110 is disposed at the right rear of the cargo box 200, and the working surface 151 of the fastener 150 of the first limiting device 110 faces the front of the cargo box 200 and is connected to the inclined surface 311 at the end of the component 310 on the rocket component 300 located at the right rear of the cargo box 200. A second limiting device 120 is positioned at the front right of the cargo box 200 of the vehicle, with the working surface 151 of the fastener 150 of the second limiting device 120 facing the rear of the cargo box 200 and connected to the inclined surface 311 at the end of the component 310 on the rocket component 300 located at the front right of the cargo box 200. Another second limiting device 120 is positioned at the rear left of the cargo box 200, with the working surface 151 of the fastener 150 facing the front of the cargo box 200 and connected to the inclined surface 311 at the end of the component 310 on the rocket component 300 located at the rear left of the cargo box 200. Since the position of the fastener 150 is adjustable, the working surface 151 of the fastener 150 can be adjusted to press against the inclined surface 311 at the end of the component 310. Thus, the rocket component 300 is limited and fixed by the four limiting devices 100 positioned within the cargo box 200.

[0041] In addition, the above-mentioned arrangement mainly restricts the movement of the rocket component 300 within the vehicle cargo box 200 along the vehicle's running direction. To further restrict the movement of the rocket component 300 within the vehicle cargo box 200 along the sides of the vehicle, it is also necessary to connect the side of the base 130 near the fastener 150 to the component 310 of the rocket component 300, thereby achieving complete horizontal positioning and fixation of the rocket component 300 and preventing damage to the component 300 during transportation.

[0042] In some embodiments, the fastener 150 is threadedly connected to the limiting member 140 so that the position of the fastener 150 on the limiting member 140 can be adjusted by rotating the fastener 150. For example... Figure 6As shown, the fastener 150 has an external thread on its outer circumferential surface. The limiting member 140 has a through hole along the width direction of the limiting device 100. One end of the through hole of the limiting member 140 near the working surface 151 of the fastener 150 is a countersunk hole 141, and the other end of the through hole of the limiting member 140 away from the working surface 151 of the fastener 150 is a threaded hole 142. The fastener 150 is threadedly connected to the threaded hole 142 of the limiting member 140. At the same time, a fixing nut 152 is provided on the second end of the fastener 150. When the fastener 150 is rotated to the required position, the fixing nut 152 on the fastener 150 is tightened, so that the fixing nut 152 abuts against the surface of the limiting member 140 near the second end of the fastener 150, thereby fixing the fastener 150 and preventing the fastener 150 from loosening during vehicle operation.

[0043] In some implementations, such as Figure 6 As shown, the fastener 150 is inclined along the length direction perpendicular to the limiting device 100, and the height of the first end of the fastener 150 with the working surface 151 is lower than the height of the second end of the fastener 150, so that the working surface 151 of the fastener 150 and the inclined surface 311 of the end of the component 310 are on the same plane and abut against each other. However, in actual use, the working surface 151 of the fastener 150 and the inclined surface 311 of the end of the component 310 may not be on the same plane. Therefore, the working surface 151 of the fastener 150 is set as a sphere, generally a sphere with a small curvature, so that the working surface 151 of the fastener 150 can be better connected with the inclined surface 311 of the end of the component 310.

[0044] In some implementations, such as Figure 4 As shown, the base 130 is bolted to the bottom of the cargo box 200. A first flange 133 is provided at the bottom of the base 130, and a through hole is formed on the first flange 133. Of course, in order to allow the base 130 to have a certain adjustment range, the through hole on the first flange 133 is generally set as an elongated hole. A screw is welded to the corresponding position at the bottom of the cargo box 200, so that the through hole of the first flange 133 on the base 130 passes through the screw inside the cargo box 200. Then, the nut is tightened on the screw, thus realizing the bolted connection between the base 130 and the cargo box 200. Of course, the base 130 and the bottom of the cargo box 200 can also be connected together by welding. This embodiment of the application does not limit this.

[0045] In some implementations, such as Figures 1-4As shown, the limiting device 100 also includes a connector 160, which surrounds the sides of the base 130 located in the width direction of the limiting device 100 and the top surface of the base 130. The second end of the limiting member 140 is connected to the connector 160, thereby connecting the limiting member 140 to the base 130 via the connector 160. Furthermore, by surrounding the base 130 with the connector 160, the stability of the connection is improved. In addition, after surrounding the base 130 with the connector 160, the surface of the connector 160 near the fastener 150 needs to be connected to the component 310 of the rocket component 300 to restrict the movement of the rocket component 300 within the vehicle cargo box 200 along the sides of the vehicle.

[0046] In some implementations, such as Figures 1-4 As shown, a first protrusion 131 is provided on the top surface of the base 130 and on the side of the base 130 away from the fastener 150. A strip groove 161 is provided on the connector 160 at the corresponding part of the top surface of the base 130 and the side of the base 130 away from the fastener 150. The first protrusion 131 of the base 130 is engaged in the strip groove 161 of the connector 160 to ensure the connection stability of the connector 160 on the base 130.

[0047] In some implementations, such as Figure 7 As shown, a second protrusion 132 is provided on the side of the base 130 near the fastener 150. A groove 162 is provided on the part of the connector 160 corresponding to the side of the base 130 near the fastener 150. The second protrusion 132 of the base 130 is engaged in the groove 162 of the base 130 to ensure the connection stability of the connector 160 on the base 130.

[0048] In some implementations, such as Figures 1-4 as well as Figure 7 As shown, the connector 160 and the base 130 are connected by fixing bolts 170 to achieve a fixed connection between the connector 160 and the base 130. Two fixing bolts 170 are provided: one fixing bolt 170 passes between the connector 160 and the first protrusion 131 of the base 130, and the other fixing bolt 170 passes between the connector 160 and the second protrusion 132 of the base 130. Furthermore, a through hole is formed in the fixing bolt 170 along its radial direction, and a cotter pin 171 is provided to prevent the nut on the fixing bolt 170 from loosening and falling off.

[0049] In some implementations, such as Figures 1-4As shown, the limiting device 100 also includes a support member 180, which is installed on the base 130 along the width direction of the limiting device 100. The fixed end of the support member 180 is disposed opposite to the first end of the fastener 150, and the fixed end of the support member 180 is connected to the inner side of the cargo box 200, so as to improve the force-bearing effect of the limiting device 100 in its width direction through the support member 180.

[0050] In some embodiments, the support member 180 may be a telescopic structure. The support member 180 may be a hydraulic cylinder, with the cylinder barrel passing through the base 130 along the width direction of the limiting device 100. The hydraulic rod is positioned opposite to the first end of the fastener 150. The support member 180 may be composed of a cylinder with internal threads and a rod with external threads. The rod is threadedly connected to the cylinder, and the telescopic function of the support member 180 is achieved by rotating the rod.

[0051] In some implementations, such as Figures 1-4 As shown, the support member 180 is bolted to the cargo box 200. A second flange 181 is provided at the fixed end of the support member 180, and a through hole is formed in the second flange 181. A screw is welded to the corresponding position on the inner side of the cargo box 200, so that the through hole of the second flange 181 on the support member 180 passes through the screw inside the cargo box 200. Then, the nut is tightened on the screw, thus realizing the bolted connection between the support member 180 and the cargo box 200. Of course, the support member 180 and the inner side of the cargo box 200 can also be connected together by welding. This embodiment of the application does not limit this method.

[0052] In some implementations, such as Figures 1-4 As shown, the limiting device 100 also includes a handle 190, one end of which is connected to the connector 160 and the other end of which is connected to the limiting member 140, so as to move the limiting device 100 through the handle 190.
