[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4 As shown, a protective net with a variable interception range is mainly composed of a No. 1 side plate 3, a No. 1 extension mechanism 8, a No. 2 extension mechanism 9 and a No. 2 side plate 10.

[0024] A shell 1 is fixedly provided on the upper end surface of the No. 1 side plate 3, a shaft rod 15 is rotatably provided inside the No. 1 side plate 3, a shaft rod 15 is fixedly provided inside the No. 2 side plate 10, a protective net 11 is wrapped around the outer side of the shaft rod 15 located inside the No. 1 side plate 3 among the two shaft rods 15, and the other end of the protective net 11 is fixedly provided on the shaft rod 15 located in the No. 2 side plate 10, and a gear 17 is fixedly sleeved on the upper end of the shaft rod 15 located in the No. 1 side plate 3 among the two shaft rods 15.

[0025] A limiting mechanism 2 is installed on one side of the housing 1 close to the upper end surface. The limiting mechanism 2 is mainly composed of a limiting rod 201 and a limiting block 202 .

[0026] The first extension mechanism 8 is composed of a first fixing plate 801, a first extension plate 802 and a first outer plate 803. The second extension mechanism 9 is composed of a second fixing plate 901, a second extension plate 902 and a second outer plate 903. A side block 6 is fixedly arranged on one side of the first fixing plate 801 and the first outer plate 803, a connection block 13 is fixedly arranged on one side of the rear end face of one of the two side blocks 6, and a splicing block 5 is fixedly arranged on one side of the front end face of the other side block 6.

[0027] Specifically, the two ends of the protective net 11 are respectively installed on two shafts 15, one of which is located in the No. 1 side panel 3, and the other is located in the No. 2 side panel 10. When the lateral interception range needs to be adjusted, the distance between the No. 1 side panel 3 and the No. 2 side panel 10 can be changed to prompt the shaft 15 in the No. 2 side panel 10 to pull the protective net 11 wrapped around the shaft 15 in the No. 1 side panel 3 to extend and open.

[0028] A clamping block 14 is fixedly arranged at the rear end of the lower end surface of the splicing block 5 , and a splicing groove 12 is opened at the rear end of the upper end surface of the connecting block 13 , and the clamping block 14 is embedded in the splicing groove 12 .

[0029] Specifically, when splicing and using, the two protection nets can be placed left and right, and then the connection blocks 13 and the splicing blocks 5 on one side of the two protection nets are spliced, and the card blocks 14 are embedded in the splicing grooves 12 to complete the splicing and combination use.

[0030] like Figure 2 As shown, cones 7 are fixedly provided on the lower end surfaces of the two side blocks 6, the No. 1 fixed plate 801 and the No. 1 outer plate 803, and there are multiple cones 7 on the lower end surfaces of the No. 1 fixed plate 801 and the No. 1 outer plate 803.

[0031] The second fixed plate 901 is fixedly arranged on the upper end of the first fixed plate 801, the second outer plate 903 is fixedly arranged on the upper end of the first outer plate 803, the first side plate 3 is fixedly arranged on one side of the upper end surface of the second fixed plate 901, and the second side plate 10 is fixedly arranged on one side of the upper end surface of the second outer plate 903.

[0032] Specifically, the multiple cones 7 arranged at the lower end can be quickly embedded in the soil for auxiliary fixation during installation, thereby improving the stability and convenience of installation; the No. 1 side panel 3 is fixed to the No. 2 fixing plate 901 and the No. 2 fixing plate 901 is connected to the No. 1 fixing plate 801, thereby realizing the linkage relationship among the three. Similarly, the No. 2 side panel 10 is fixed to the No. 2 outer panel 903 and the No. 2 outer panel 903 is connected to the No. 1 outer panel 803, thereby also completing the linkage relationship among the three.

[0033] like Figure 4A rectangular through hole 16 is opened on one side of the upper end surface of the housing 1, and a limiting rod 201 is arranged through the through hole 16. A limiting block 202 is fixedly arranged at the lower end of the limiting rod 201 and embedded between the teeth of the gear 17.

[0034] Specifically, when in use, the limiting rod 201 can be pulled upward to drive the limiting block 202 at the lower end to move upward. At this time, the limiting block 202 disengages from the locking teeth of the gear 17 and no longer restricts the rotation of the gear 17, so that the shaft 15 at the lower end of the gear 17 can rotate; and when the limiting block 202 is stuck between the locking teeth of the gear 17, the limiting effect on the gear 17 and the lower end shaft 15 is completed.

[0035] Combination Figure 1-3 As shown, the first extension plate 802 is fixedly arranged on one side of the first fixed plate 801, and the side of the first extension plate 802 away from the first fixed plate 801 is slidably embedded in the first outer plate 803. The second extension plate 902 is fixedly arranged on one side of the second fixed plate 901, and the adjustment rod 4 is rotatably arranged inside the second extension plate 902, and the second fixed plate 901 is threadedly sleeved with the adjustment rod 4, and the end of the second extension plate 902 away from the second fixed plate 901 is slidably arranged in the second outer plate 903.

[0036] Specifically, when in use, the outer adjusting rod 4 is rotated to push the No. 2 extension plate 902 with the outer threaded sleeve outward. At this time, the distance between the No. 2 fixed plate 901 and the No. 2 outer plate 903 changes, and the distance between the No. 1 fixed plate 801 at the lower end and the No. 1 outer plate 803 also changes; and when the distance between the No. 2 fixed plate 901 and the No. 2 outer plate 903 changes, the distance between the No. 1 side plate 3 and the No. 2 side plate 10 at the upper end also changes. At this time, the limiting mechanism 2 does not limit the shaft 15 with the gear 17, so as to complete the extended use of the wrapped protective partition net 11.

[0037] Working principle: When the protective net is in use and the lateral interception range needs to be adjusted, the limiting mechanism 2 can be first moved upward so that it no longer restricts the shaft 15 with the gear 17, and then the adjusting rod 4 is rotated to drive the No. 2 fixed plate 901 and the No. 2 extension plate 902 to move outward, causing the distance between the No. 2 fixed plate 901 and the No. 2 outer plate 903 to change, and the distance between the No. 1 side plate 3 and the No. 2 side plate 10 at the upper end to change accordingly, and then in the process of the distance between the No. 1 side plate 3 and the No. 2 side plate 10 changing accordingly, the protective partition net 11 wrapped around the outside of the shaft 15 with the gear 17 will be pulled to extend, thereby realizing the adjustment of the lateral interception range;

[0038] Secondly, the two protective nets can also be spliced ​​together in the horizontal direction, and the splicing blocks 5 and the connecting blocks 13 on both sides can be used for rapid splicing, thereby also playing the role of splicing and expanding the horizontal interception range.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
