With the continuous development of technology, the performance requirements for signal source devices are getting higher and higher, including signal accuracy, stability, flexibility, and versatility. In such a technical background, the measurement and control circuit signal source technology of existing signal source devices has been continuously evolving to meet the growing application requirements. However, the structural design of existing signal source devices has always adopted the structure of conventional instruments. When in use, the device needs to be placed on a plane and supported by four legs at the bottom. In this way, the device has high requirements for the use environment, low use flexibility, and also reduces the calibration efficiency. Moreover, when the existing signal source device is bumped or toppled during use, it is easy to cause impact damage to the internal electronic components, and its anti-impact ability is low. In addition, for the existing signal source device, its structural layout is not compact enough, resulting in a large external volume of the device, which is not convenient for storage and transportation. Therefore, it is necessary to optimize the structure design of the existing signal source device. Summary of the Invention

[0042] In this way, the device structure layout is compact, and the external shape and volume of the device are small, which is convenient for storage and carrying.

[0043] A lower foot 31 is provided at each of the left and right corner positions at the lower end of the body. The lower foot 31 has a support portion 311 extending horizontally.

[0044] The bracket 4 is made of aerospace-grade aluminum alloy material. The upper end of the bracket 4 is hinged to the upper side of the rear end face of the body through a hinge 41. The lower end of the bracket 4 can swing relative to the body to a set angle, and moreover, the hinge 41 can keep the lower end of the bracket 4 relative to the body at the set angle. Among them, the hinge 41 can keep the lower end of the bracket 4 relative to the body at 0° (at this time, the lower end of the bracket 4 fits the body), 45° and 90°. When the bracket 4 is in the folded state (the lower end of the bracket 4 fits the body), the device has a small volume and is convenient for storage and transportation; in the unfolded state of the bracket 4, it provides a stable support for the body and can withstand a high-frequency vibration environment.

[0045] A bracket limiting member 5 is provided at the lower side of the rear end surface of the machine body, and when the lower end of the bracket 4 is attached to the machine body, the bracket limiting member 5 is detachably connected to the lower end of the bracket 4. The bracket limiting member 5 is provided as a bayonet, and the lower end of the bracket 4 is provided as a rod, and the rod is engaged with the bayonet to realize the detachable connection between the lower end of the bracket and the bracket limiting member 5.

[0046] The lower end of the bracket 4 is wrapped with an anti-slip member 42, which is made of a material with a high friction coefficient, specifically made of rubber with a high friction coefficient. By wrapping the anti-slip member 42 at the lower end of the bracket 4, the lower end of the bracket 4 is prevented from sliding between the position where the device is to be placed, thereby improving the support stability. In addition, the anti-slip member 42 is also engaged with the bayonet to achieve a detachable connection between the lower end of the bracket and the bracket limiter 5.

[0047] When the device is in use, if the position where the device is to be placed is a plane, the lower guard foot 31 can directly contact the position where the device is to be placed, and the support portion 311 of the lower guard foot 31 can be used to achieve stable support for the body. If the position where the device is to be placed is not a plane, the lower end of the bracket 4 is swung to a set angle (such as 45°) relative to the body, and the hinge 41 keeps the lower end of the bracket 4 at the set angle relative to the body, so that the rear ends of the two lower guard feet 31 and the lower end of the bracket 4 form three support points to achieve stable support for the body. In this way, the device has good adaptability to the use environment, is flexible to use, and also improves the efficiency of measurement and calibration.

[0048] The left and right sides of the machine body are each wrapped with a sheath 30, the lower end of the sheath 30 protrudes outward to form a lower foot 31, and the upper end of the sheath 30 protrudes outward to form an upper foot 32. The sheath 30 wraps and protects the left and right sides of the machine body, and the lower foot 31 and the upper foot 32 wrap and protect the four corners of the machine body. The outer contours of the lower foot 31 and the upper foot 32 are both semi-cylindrical in longitudinal section. When the position where the equipment is to be placed is a plane, the support portion 311 of the lower foot 31 and the contact area with the position where the equipment is to be placed are in the shape of a line, so that the support portion 311 of the lower foot 31 can achieve stable support for the machine body. When the position where the equipment is to be placed is a non-plane, the support portion 311 at the rear end of the two lower feet 31 and the contact area with the position where the equipment is to be placed are in the shape of a point, which can form three support points with the lower end of the bracket 4 to achieve stable support for the machine body.

[0049] The middle position of the sheath 30 is provided with an assembly groove 301, which matches the outer contours of the left and right sides of the machine body, and the edge position of the sheath 30 is assembled and connected to the machine body by screws. In this way, the sheath 30 is firmly matched with the machine body, and the sheath 30 wraps the left and right sides of the machine body.

[0050] The sheath 30, the lower foot guard 31 and the upper foot guard 32 are integrally formed. The three are made of a composite high-strength material, with anti-collision, anti-slip and wear-resistant functions, effectively preventing damage to the equipment caused by mechanical impact or accidental damage during transportation and use, and at the same time enhancing the durability and service life of the equipment.

[0051] The sheath 30 is provided on the left and right sides of the body, and the foot guards (the lower foot guard 31 and the upper foot guard 32) are provided at the four corners of the equipment. When the equipment is bumped or tilted during use, the anti-impact ability of the equipment is improved, the impact on the internal electronic components is weak, and the service life of the internal electronic components is extended.

[0052] A handle 6 is connected to the sheath 30 on the left side of the body. The user holds the handle 6 to facilitate carrying the equipment. The handle 6 is made of aluminum alloy material and has been subjected to anti-corrosion treatment, conforming to the ergonomic design, facilitating the lifting and moving of the equipment, and is suitable for scenarios that require frequent movement such as field exploration.

[0053] So far, this embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the radar calibration signal source equipment of the present invention. When the radar calibration signal source equipment described in the present invention is in use, if the position where the equipment is to be placed is a plane, the lower foot guard 31 can directly contact the position where the equipment is to be placed, and the support portion 311 of the lower foot guard 31 is used to achieve stable support for the body; if the position where the equipment is to be placed is a non-plane, the lower end of the bracket 4 is swung relative to the body to a set angle, and the hinge 41 is used to keep the lower end of the bracket 4 relative to the body at the set angle, so that the rear ends of the two lower foot guards 31 and the lower end of the bracket 4 form three support points to achieve stable support for the body; in this way, the equipment has good adaptability to the use environment, is flexible in use, and also improves the calibration efficiency. The sheath 30 is provided on the left and right sides of the body, and the foot guards are provided at the four corners of the equipment.
