[0027] Specific implementation method.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 5 The tent-type police fence includes a cylinder 2, a pressing plate 1 is installed on the top of the cylinder 2, and four supporting legs are installed at the edge of the pressing plate 1, that is, a plurality of spaced slots 11 are opened at the edge of the pressing plate 1, and a rotating shaft 12 is vertically installed on both sides of the slot 11, so that the supporting legs can be rotated and adjusted on the side of the pressing plate 1, and each supporting leg includes a first support rod 17, and a first connecting seat 18 is installed at one end of the first support rod 17. The first connecting seat 18 is placed in the slot 11 and is rotatably connected to the rotating shaft 12, and a second connecting seat 19 is installed at the other end of the first support rod 17. The second connecting seat 19 is rotatably installed in a "U"-shaped first fixed seat 20 through a rotating shaft, and a second support rod 21 is installed on the other end of the first fixed seat 20, so that the support rods can be bent for storage, and at the same time, the support rods can be supported on the ground after being unfolded, so that an upward arched state is formed between the entire supporting leg and the cylinder 2.

[0030] Among them, when the first support rod 17 and the second support rod 21 are bent, after being bent to a suitable angle, a locking bolt is spirally connected to the first fixing seat 20, and the end of the locking bolt corresponds to the second connecting seat 19 placed in the first fixing seat 20. The locking bolt can be screwed to fix the first support rod 17 and the second support rod 21 to prevent the rotational connection between the first support rod 17 and the second support rod 21 from affecting the support of the support tripod.

[0031] In order to facilitate the carrying of the police enclosure, the first support rod 17 and the second support rod 21 are both hollow tubes, which reduces the weight of the support rods and improves the lightweight of the supporting tripod.

[0032] The bottom of the cylinder 2 is open, and a through groove 3 is provided on the side of the cylinder 2. The through groove 3 is provided along the axial direction of the cylinder 2. A sleeve 5 is provided at the bottom of the cylinder 2. A gap is left between the bottom of the sleeve 5 and the bottom of the cylinder 2. A first compression spring 4 is also provided in the cylinder 2. One end of the first compression spring 4 is fixed to the top of the cylinder 2, and the other end of the first compression spring 4 is fixed to the bottom of the sleeve 5. A drive frame connected to the support bracket is provided on the side of the sleeve 5. A plurality of spaced connecting shafts 16 are provided on the side of the sleeve 5. The end of the connecting shaft 16 is fixed to the mounting seat 15. The mounting seat 15 is fixed on the outer wall of the sleeve 5, and the driving frame includes a third support rod 23. The ends of the third support rod 23 are each installed with a third connecting seat 24, one of the third connecting seats 24 is rotatably connected to the connecting shaft 16, and the other third connecting seat 24 is rotatably mounted on a "U"-shaped second fixing seat 25, and the second fixing seat 25 is fixed on the connecting tube 22, and the connecting tube 22 is coaxially fixed on the first support rod 17, so that the sleeve 5 can slide on the cylinder 2, that is, when the sleeve 5 slides on the cylinder 2, the driving frame can be pulled or pushed, so that the supporting leg can be switched between the retracted and deployed states;

[0033] Among them, under the elastic action of the first compression spring 4, the sleeve 5 can be pushed outward from the cylinder 2, and at this time, the driving frame can be driven to push the supporting leg, so that the supporting leg can be unfolded. At least one bayonet hole 6 is opened on the side of the sleeve 5, and the bayonet hole 6 passes through the side wall of the sleeve 5, and a through hole 7 is opened at the upper end of the side of the cylinder 2, and a accommodating tube 8 corresponding to the through hole 7 is installed on the inner wall of the cylinder 2, and a fixing pin 9 is built into the through hole 7. The fixing pin 9 corresponds to the bayonet hole 6, and when the fixing pin 9 is close to the A second compression spring 10 is connected to one end near the accommodating tube 8, and the other end of the second compression spring 10 is fixed to the end of the accommodating tube 8. When the sleeve 5 is pulled upward, the fixing pin 9 is placed in the bayonet hole 6, thereby limiting and fixing the sleeve 5 on the cylinder 2, so that the foldable support leg can be stored and the compressed state of the first compression spring 4 can be fixed, so that the elasticity of the first compression spring 4 will not act on the sleeve 5, thereby unfolding the support leg and maintaining the stored state of the support leg.

[0034] The present invention also includes a tarpaulin 26, the top of the tarpaulin 26 is fixed to the bottom of the sleeve 5, and the side of the tarpaulin 26 is fixed to the support frame; a plurality of straps 27 are installed on the side of the tarpaulin 26, and the straps 27 correspond to the first support rod 17 and the second support rod 21 respectively, and are used to fix the tarpaulin 26 on the support frame.

[0035] Specifically, during use, when the tarpaulin 26 is not opened, the first compression spring 4 is in a compressed state, and the fixing pin 9 on the cylinder 2 is inserted into the bayonet hole 6 on the sleeve 5. When the fixing pin 9 is pressed to retract into the accommodating tube 8, the sleeve 5 can slide down from the cylinder 2, allowing the first compression spring 4 to return to its original state and push the sleeve 5 to move downward. At this time, the tarpaulin 26 is in an expanded state; when retracting, the sleeve 5 is pulled upward, and the upper end surface of the sleeve 5 contacts the fixing pin 9 when moving upward. The fixing pin 9 is retracted under force until it rises to the point where the fixing pin 9 corresponds to the bayonet hole 6. The elastic force of the second compression spring 10 will push the fixing pin 9 into the bayonet hole 6 and limit and fix the sleeve 5. The first compression spring 4 is in a compressed state, and the support rod loses the supporting force of the drive frame and can be fully retracted.

[0036] It should be noted that a handle 13 is provided above the pressing plate 1 , and slots 14 are provided on the inner sides of both ends of the bottom of the handle 13 , and the slots 14 correspond to the rotating shaft 12 , so as to facilitate the carrying and transport of the police enclosure.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
