[0002] With the continuous updating of modern equipment, civilian ejection devices such as fire extinguishers, tube-type launch folding aircrafts and civilian ammunition boxes (such as rainfall ammunition boxes launched by artificial rainfall) emerge in endlessly. Due to the different structural characteristics of different types of equipment, the installation methods of their installation interfaces also have great differences.

[0003] The traditional equipment installation interface is generally designed on the front and vertical side or tail of the equipment. The separation method is generally that the plug and the socket are separated during launching. The installation method of the plug and the socket is particularly important when installing the cable. The stress direction of the cable as a whole should be consistent with the launching direction of the ammunition. However, with the diversification of the design of the equipment interface, the design position of the interface is often affected by the internal structure of the equipment, and it is often difficult to find a reasonable fixing position for installation, resulting in a tricky interface angle and narrow space.

[0004] Therefore, for different types of equipment, how to reasonably install the equipment interface has become a difficult problem to be solved in the installation of electrical and mechanical interfaces. SUMMARY

[0005] The present application provides an adjustable pull-off bracket, which can solve the technical problem that different types of intelligent equipment cannot be reasonably installed with an equipment interface in the prior art.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] The embodiment of the present application provides an adjustable pull-off support which can solve the technical problem that different types of intelligent devices cannot be reasonably installed with device interfaces in the prior art.

[0031] With reference to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic diagram of an adjustable pull-off support according to an embodiment of the present application, Figure 2 FIG. 2 is a schematic diagram of the adjustable pull-off support according to an embodiment of the present application, wherein an interface 6 is installed on the adjustable pull-off support. Figure 1 and Figure 2 As shown in FIGS. 1 and 2, the adjustable pull-off support includes a base 1, a height adjustment mechanism 2, an angle adjustment mechanism 3 and a mounting rack 4.

[0032] The base 1 can be installed on a platform or fixed on the ground and mainly serves as a support. The height adjustment mechanism 2 is installed on the base 1 and serves to adjust the height of the base 1. The angle adjustment mechanism 3 is installed on the height adjustment mechanism 2, for example, at the top end of the height adjustment mechanism 2, so that the angle adjustment mechanism 3 can freely adjust the angle around a part or a point of the height adjustment mechanism 2 to adapt to the installation angle of different interfaces 6 corresponding to different devices. The mounting rack 4 is installed on the angle adjustment mechanism 3 and mainly serves to install the interface 6. In addition, different types of interfaces 6 are required for different devices, and different sizes of mounting holes 4211 can be formed in the mounting rack 4 to install different types of interfaces 6.

[0033] Specifically, the bottom end of the height adjustment mechanism 2 is arranged on the base 1 and can adjust the height in the vertical direction. The angle adjustment mechanism 3 is installed at the top end of the height adjustment mechanism 2 and includes a connecting rod 31 which can rotate around the top end of the height adjustment mechanism 2 to adjust the angle. The mounting rack 4 includes a rack body 41 and a mounting plate 42 which are fixed to each other. The other end of the connecting rod 31 penetrates through the rack body 41 and is connected to the mounting plate 42 through a steel cable 5. The mounting plate 42 is further provided with mounting holes 4211 for installing the interface 6.

[0034] The height adjusting mechanism 2 can be formed by several hollow rods nested together, and is adjusted in the vertical direction to achieve height adjustment. One end of the connecting rod 31 is rotatably installed at the top end of the height adjusting mechanism 2, and the other end passes through the frame body 41 and is connected to the mounting plate 42 through the steel cable 5. Meanwhile, to avoid interference between the installation positions of the steel cable 5 and the interface 6, the installation position of the steel cable 5 is staggered with the installation position of the interface 6. The mounting hole 4211 can be used to directly fix the interface 6, and according to the type of the interface 6 required by different devices, the appropriate size of the mounting hole 4211 is drilled on the mounting plate 42. The steel cable 5 can be formed by several steel rings connected in series, or only one “elliptical” steel cable 5, and the two ends can be fixed on the connecting rod 31 and the mounting plate 42 through a draw pin and a draw buckle respectively.

[0035] In this embodiment, the bottom end of the height adjusting mechanism 2 is arranged on the base 1 to achieve height adjustment in the vertical direction, and the angle adjusting mechanism 3 is installed at the top end of the height adjusting mechanism 2, and one end of the connecting rod 31 of the angle adjusting mechanism 3 can rotate around the top end of the height adjusting mechanism 2, and the other end passes through the frame body 41 and is connected to the mounting plate 42 through the steel cable 5. The mounting plate 42 is also provided with a mounting hole 4211 for installing the interface 6. First, the height adjusting mechanism 2 is adjusted in the vertical direction relative to the base to adjust the height of the mounting bracket 4, so that the interface 6 on the mounting bracket 4 is close to the corresponding position on the device, and then one end of the connecting rod 31 is rotated, and at the same time the mounting bracket 4 can also be rotated around the top end of the height adjusting mechanism 2 through the connecting rod 31, so that the interface 6 on the mounting bracket 4 is connected with the device, and the connection can communicate. The height adjusting mechanism 2 can adjust the height in the vertical direction relative to the base 1, and one end of the connecting rod 31 of the angle adjusting mechanism 3 can rotate around the top end of the height adjusting mechanism 2, and the other end passes through the frame body 41 and is connected to the mounting plate 42 through the steel cable 5, to achieve different angle adjustment of the mounting bracket 4 in the four directions. In this way, the interface 6 arranged on the mounting bracket 4 can be adjusted to a reasonable fixed position and connected with the device, and the adaptive installation of the interface can be completed in a narrow space. Through this embodiment, the technical problem that the device interface 6 cannot be reasonably installed for different types of devices in the prior art is effectively solved.

[0036] In addition, when the device is transmitting, the device will exert a pulling force on the mounting bracket 4 towards the transmission direction, but since the mounting bracket 4 can be freely adjusted in angle at the top end of the height adjusting mechanism 2 through the connecting rod 31, the mounting bracket 4 can temporarily adjust its own angle following the device, and then the interface 6 on the mounting bracket 4 is disconnected with the device.

[0037] Further, in an embodiment, as shown in FIG. 6, the height adjusting mechanism 2 is arranged on the base 1 to achieve height adjustment in the vertical direction, and the angle adjusting mechanism 3 is installed at the top end of the height adjusting mechanism 2, and one end of the connecting rod 31 of the angle adjusting mechanism 3 can rotate around the top end of the height adjusting mechanism 2, and the other end passes through the frame body 41 and is connected to the mounting plate 42 through the steel cable 5. The mounting plate 42 is also provided with a mounting hole 4211 for installing the interface 6. First, the height adjusting mechanism 2 is adjusted in the vertical direction relative to the base to adjust the height of the mounting bracket 4, so that the interface 6 on the mounting bracket 4 is close to the corresponding position on the device, and then one end of the connecting rod 31 is rotated, and at the same time the mounting bracket 4 can also be rotated around the top end of the height adjusting mechanism 2 through the connecting rod 31, so that the interface 6 on the mounting bracket 4 is connected with the device, and the connection can communicate. The height adjusting mechanism 2 can adjust the height in the vertical direction relative to the base 1, and one end of the connecting rod 31 of the angle adjusting mechanism 3 can rotate around the top end of the height adjusting mechanism 2, and the other end passes through the frame body 41 and is connected to the mounting plate 42 through the steel cable 5, to achieve different angle adjustment of the mounting bracket 4 in the four directions. In this way, the interface 6 arranged on the mounting bracket 4 can be adjusted to a reasonable fixed position and connected with the device, and the adaptive installation of the interface can be completed in a narrow space. Through this embodiment, the technical problem that the device interface 6 cannot be reasonably installed for different types of devices in the prior art is effectively solved. Figure 1As shown, the top end of the height adjusting mechanism 2 is provided with a mounting seat 32, a rotatable ball 33 is installed in the mounting seat 32, and one end of the connecting rod 31 is fixedly connected with the ball 33. In this embodiment, the mounting seat 32 can be provided with an inner cavity with an opening for installing the ball 33, the ball 33 can rotate in the inner cavity, and one end of the connecting rod 31 is fixedly connected with the ball 33. At this time, the ball 33 can be entirely arranged in the mounting seat 32, or part of the volume of the ball 33 can be exposed outside the mounting seat 32. By providing the mounting seat 32 at the top end of the height adjusting mechanism 2, installing the rotatable ball 33 in the mounting seat 32, and fixedly connecting one end of the connecting rod 31 with the ball 33, the connecting rod 31 can better rotate around the top end of the height adjusting mechanism 2, the adjusting direction is more convenient, and the operation is simple.

[0038] Further, in an embodiment, as shown in Figure 1 the mounting seat 32 is provided with an inner cavity with an opening, and the ball 33 is installed in the inner cavity, and a friction pair is formed between the cavity wall of the inner cavity and the ball 33. In this embodiment, by providing the mounting seat 32 with an inner cavity with an opening, and installing the ball 33 in the inner cavity, and forming a friction pair between the cavity wall of the inner cavity and the ball 33, the ball 33 and the cavity wall of the inner cavity are in direct contact and relative friction motion, which not only effectively prevents the ball 33 from falling out of the inner cavity, but also easily corrects the position of the interface 6 on the mounting frame 4 without the aid of other fixing tools, is convenient to operate, and has high practicability.

[0039] Further, in an embodiment, as shown in Figure 1 part of the volume of the ball 33 is protruded outside the cavity opening and fixedly connected with the connecting rod 31, and the volume of the ball 33 outside the cavity opening is smaller than the volume of the ball 33 inside the cavity opening. In this embodiment, by protruding part of the volume of the ball 33 outside the cavity opening and fixedly connecting it with the connecting rod 31, and making the volume of the ball 33 outside the cavity opening smaller than the volume of the ball 33 inside the cavity opening, the adjusting angle of the connecting rod 31 can be wider, and the adjusting flexibility is higher while ensuring that the ball 33 does not fall out of the inner cavity.

[0040] Further, in an embodiment, as shown in Figure 1 the cavity opening is provided with a reinforcing ring 34 for preventing the ball 33 from falling out. In this embodiment, by providing the cavity opening with the reinforcing ring 34 for preventing the ball 33 from falling out, the ball 33 can be further limited in the inner cavity, which is equivalent to adding an “insurance” to the ball 33, preventing the ball 33 from falling out of the inner cavity due to excessive amplitude or force of the connecting rod 31.

[0041] Further, in an embodiment, as shown in Figure 2As shown, the base 1 and the height adjustment mechanism 2 are provided with a cable accommodating channel 11, one end of which is arranged on the base 1 and the other end is arranged on the height adjustment mechanism 2. In this embodiment, the cable needs to be connected with the interface 6 on the mounting frame 4. By arranging the cable accommodating channel 11 on the base 1 and the height adjustment mechanism 2, one end of which is arranged on the base 1 and the other end is arranged on the height adjustment mechanism 2, a clear path for the cable is provided, so that the cable can be arranged in an orderly and tidy manner, avoiding the disorderly and random pulling of the cable, and improving the reliability and safety of the cable. At the same time, it also reduces the damage and failure risk of the cable caused by random pulling or stepping.

[0042] Further, in an embodiment, as shown in Figure 1 The height adjustment mechanism 2 is formed by stacking several hollow rods and is fixed by a height nut. The port is arranged on the innermost hollow rod 21, and the protruding end of the innermost hollow rod 21 is fixedly provided with a mounting seat 32. In use, the innermost hollow rod 21 is preferentially extended. In this embodiment, the height adjustment mechanism 2 is formed by stacking several hollow rods and is fixed by a height nut, so that flexible height adjustment can be achieved while maintaining a compact structure, which is conducive to precise fixing of the height position, thereby meeting different use requirements. By arranging the port of the cable accommodating channel 11 on the innermost hollow rod 21 and fixing the mounting seat 32 of the foregoing embodiment on the protruding end of the innermost hollow rod 21, the innermost hollow rod 21 is preferentially extended in use. This can ensure that the protruding end of the innermost hollow rod 21 is always supported by the mounting seat 32, and when the innermost telescopic rod is extended, the cable inside the hollow rod can also be moved synchronously.

[0043] In addition, in other embodiments, the surfaces of the several hollow rods are each provided with a height identification scale. The height identification scale can provide an intuitive and quantitative height reference, so that the user can more accurately measure and adjust the height of the hollow rod.

[0044] Further, in an embodiment, as shown in Figure 1As shown, the mounting plate 42 includes a first mounting plate 421 for mounting the interface 6 and a second mounting plate 422 for connecting with the steel cable 5, and the first mounting plate 421 and the second mounting plate 422 are connected through the frame 41. In this embodiment, by arranging the first mounting plate 421 for mounting the interface 6 and the second mounting plate 422 for connecting with the steel cable 5, and connecting the first mounting plate 421 and the second mounting plate 422 through the frame 41, a stable whole is formed among the first mounting plate 421, the second mounting plate 422 and the frame 41, and greater external force and load can be borne, and meanwhile, the steel cable 5 and the interface 6 are mounted on different mounting plates 42, so that their mounting positions do not interfere with each other, which is beneficial to adapt to some tricky installation angles.

[0045] Further, in an embodiment, as shown, the frame 41 is in a door frame structure, the first mounting plate 421 is mounted at the opening of the door frame structure, the second mounting plate 422 is located in the door frame structure and is parallel to the first mounting plate 421, and the two ends of the steel cable 5 are connected to the mounting plate 42 and the frame 41 through a draw pin and a draw buckle respectively. Figure 1 In this embodiment, through the above structure, the structure of the frame 41 is more stable, which is beneficial to resist external forces such as wind force and vibration. In addition, the steel cable 5 is closely connected to the mounting plate 42 and the frame 41 through the draw pin and the draw buckle, so that the load can be effectively transmitted and dispersed, and local overload and damage can be avoided.

[0046] Further, in an embodiment, the interface 6 is connected with the device, and the pulling force of the device during emission is greater than the plug-in force between the interface 6 and the device. In this embodiment, the interface 6 on the mounting rack 4 is connected with the device, so that communication can be realized, but when the device emits, the pulling force of the device during emission is greater than the plug-in force between the interface 6 and the device, so that the device and the interface 6 on the mounting rack 4 can be separated.

[0047] When the device emits, under normal circumstances, the device will exert a pulling force on the mounting rack 4 towards the emission direction, but since the mounting rack 4 can be freely adjusted in angle at the top end of the height adjusting mechanism 2 through the connecting rod 31, the mounting rack 4 can temporarily adjust its own angle following the device, and then the interface 6 on the mounting rack 4 is disconnected with the device. However, there is an extreme case that when the interface 6 on the mounting rack and the device are too tightly matched, the plug-in force will be too large, and even greater than the bearing force of the steel cable 5, at this time the steel cable 5 will be pulled off, causing the mounting rack 4 and the angle adjusting mechanism 3 to be separated, and the cable will be pulled off, so that the mounting rack 4 is emitted together with the device, ensuring the smooth emission of the device.

[0048] In addition, in other embodiments, the interface 6 on the mounting rack 4 and the device can also be connected through an adapter wire, but the pulling force of the device during emission needs to be greater than the plug-in force between the interface on the adapter wire and the device.
