[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model discloses a portable signal jammer, comprising a signal jammer 1, a sliding assembly 2 which can be moved and locked along the length direction of the signal jammer 1 is provided at the bottom of the signal jammer 1, and a rotatable and foldable tripod stand 3 is provided at one end of the sliding assembly 2 away from the signal jammer 1;

[0023] A sliding groove is provided at the bottom of the signal jammer 1 for the sliding component 2 to move. One end of the sliding groove is located at the center of gravity of the bottom of the signal jammer 1. When the sliding component 2 is located at the other end of the sliding groove, the length of the tripod bracket 3 after folding does not exceed the length of the signal jammer 1.

[0024] The utility model integrates the tripod 3 into the bottom of the signal jammer 1 by providing a sliding component 2, so that the tripod 3 can be folded at the bottom of the signal jammer 1 when not in use and can be carried together with the signal jammer 1. At the same time, because the sliding component 2 can slide and lock at the bottom of the signal jammer 1, the tripod 3 can be folded so as not to exceed the bottom area of ​​the signal jammer 1, and can ensure that the tripod 3 has sufficient telescopic length after being unfolded, thereby achieving the purpose of being able to be quickly deployed and stored and carried.

[0025] During specific implementation, a sink is provided on the top of the signal jammer 1, and a handle is provided in the sink for rotation, which is convenient for users to carry and move. At the same time, an antenna external interface is also provided on the signal jammer 1 for connecting different types of antennas to improve environmental applicability.

[0026] In one embodiment, the sliding assembly 2 includes a connecting tube 21, one end of which is inserted into the sliding groove, and the other end is rotatably connected to the tripod 3. A rotating groove is provided on the connecting tube 21 for the tripod 3 to rotate toward the center of gravity of the bottom of the signal jammer 1. A screw sleeve 22 is threadedly connected on the connecting tube 21 for sealing the rotating groove after the tripod 3 is unfolded.

[0027] With this design, when the screw sleeve 22 is rotated to block the rotating groove, the tripod stand 3 cannot be folded to one side along the rotating groove, so that the tripod stand 3 after being unfolded can remain in the unfolded state. Conversely, when the tripod stand 3 needs to be folded, it is only necessary to rotate the screw sleeve 22 in the opposite direction to expose the rotating groove, and then the tripod stand 3 can be rotated and folded, making the folding and unfolding operation of the tripod stand 3 quick and convenient.

[0028] In one embodiment, at least one rectangular positioning block 23 is provided at one end of the connecting tube 21 located in the slide groove and plugged into the signal jammer 1. A guide groove 4 is provided in the signal jammer 1 for the rectangular positioning block 23 to move.

[0029] The guide groove 4 includes a horizontal groove in the same direction as the slide groove and two vertical grooves arranged at both ends of the horizontal groove. The vertical groove close to the center of gravity of the bottom of the signal jammer 1 is located at the top of the horizontal groove, and the vertical groove away from the center of gravity of the bottom of the signal jammer 1 is located at the bottom of the horizontal groove.

[0030] With this design, when the connecting tube 21 is moved to the vertical groove near the center of gravity of the bottom of the signal jammer 1 through the rectangular positioning block 23, the tripod 3 is unfolded and placed on the ground. Due to the gravity of the signal jammer 1 itself, the rectangular positioning block 23 will be stably inserted into the vertical groove, so that the tripod 3 can maintain its center of gravity position unchanged during use. When the tripod 3 is folded, the connecting tube 21 is moved to the vertical groove away from the center of gravity of the bottom of the signal jammer 1 through the rectangular positioning block 23. Due to the weight of the tripod 3 itself, the rectangular positioning block 23 can also be maintained in the vertical groove, preventing the tripod 3 from shaking at will when carrying. The entire locking process utilizes the equipment's own gravity, effectively improving operational efficiency.

[0031] In a specific implementation, a screw rod for locking the rectangular positioning blocks 23 in the two vertical grooves can be added to the signal jammer 1. By adjusting the tightness of the screw rod, the connection stability of the rectangular positioning blocks 23 can be further improved.

[0032] In one embodiment, at least two support plates 5 are provided at the bottom of the signal jammer 1, and a support bar 6 located at the bottom of the folded tripod 3 is detachably provided between the two support plates 5, and the support bar 6 is also located between the two vertical grooves.

[0033] With this design, the support bar 6 is used to support the folded tripod 3, so that the tripod 3 will not rotate downward to unfold when carried. When the tripod 3 needs to be unfolded, it is only necessary to manually lift the tripod 3 to move the rectangular positioning block 23 from the vertical groove to the horizontal groove, and then move it along the horizontal groove to the other vertical groove, so that it can cross the supporting area of ​​the support bar 6 and smoothly rotate and unfold the tripod 3.

[0034] In one embodiment, the height of the support plate 5 is not less than the maximum distance between the tripod stand 3 and the signal jammer 1 after folding.

[0035] This design ensures that when the signal jammer 1 is placed on the ground, it contacts the ground through the support plate 5 and will not affect the folded tripod 3, thereby avoiding the tripod 3 being mis-locked due to the lowering operation of the signal jammer 1.
