[0025] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In the embodiment of the present utility model, Figure 1-Figure 3 As shown, the tool for temporarily plugging a reserved hole comprises a baffle 1, a plurality of supporting legs 2 and a plurality of collars 4; the baffle 1 is formed with a plurality of through holes 101, each of the through holes 101 is provided with a notch 102 connected thereto; a plurality of supporting legs 2 are respectively inserted into the through holes 101; a plurality of collars 4 are respectively sleeved on the supporting legs 2 with gaps, and a protrusion 5 adapted to the notch 102 is extended outward from the surface of the collar 4, so that when the collar 4 links the protrusion 5 to rotate, the protrusion 5 and the corresponding notch 102 are formed in an overlapping state or a staggered state; in the overlapping state, the baffle 1 and the protrusion 5 can move relative to each other to open the reserved hole; in the staggered state, the protrusion 5 restricts the movement of the baffle 1 to cover the reserved hole.

[0027] Specifically, in the embodiment of the utility model, the reserved opening is a rectangular structure, the baffle 1 is used to cover the reserved opening, and its edges protrude outside the reserved opening. On the one hand, it can prevent the baffle 1 from falling and play a role in closing the reserved opening. On the other hand, it can replace the traditional protective railings to facilitate passage.

[0028] In the embodiment of the utility model, in order to prevent the baffle 1 from moving or losing, the baffle 1 is provided with a plurality of through holes 101 (the number of through holes 101 can be selected according to actual conditions and is not limited here), and each through hole 101 is pierced with a support leg 2; during installation, a part of the support leg 2 is used to be suspended in the reserved hole and abut against the inner wall of the reserved hole, and the other part of the support leg 2 protrudes above the baffle 1 for installing the collar 4; the collar 4 is an annular structure and is gap-mounted outside the support leg 2 so as to slide axially along the support leg 2 and rotate circumferentially along the support leg 2; the outer surface of the collar 4 is provided with an integrated protrusion 5, and each through hole 101 is provided with a notch 102, the through holes 101 and the notch 102 are connected one by one, and the protrusion 5 is adapted to the notch 102; in this way, when the collar 4 is rotated, it can The protrusion 5 is moved so that the protrusion 5 and the notch 102 form an overlapping state or a staggered state. In the overlapping state, since there is a clearance fit between the notch 102 and the protrusion 5, and between the through hole 101 and the supporting leg 2, the baffle 1 can be put into or taken out of the supporting leg 2, so as to realize quick installation and disassembly, and facilitate storage; in the staggered state, since the ring 4 can slide along the axial direction of the supporting leg 2, the protrusion 5 can be slid to the top of the baffle 1, and rotated to stagger the protrusion 5 and the notch 102. On the one hand, the supporting leg 2 can be fixed on the baffle 1, and the baffle 1 can be limited to the reserved hole under the action of the supporting leg 2 and the inner wall of the reserved hole, so as to avoid the baffle 1 from shifting or losing. On the other hand, the protrusion 5 can press the baffle 1 to the ground, so as to isolate dust and prevent falling objects from high altitude.

[0029] When in use, insert each support leg 2 into the corresponding through hole 101, then rotate the ring 4 to stagger the protrusion 5 and the corresponding notch 102, and finally place the tool as a whole at the reserved hole so that the support leg 2 abuts against the inner wall of the reserved hole.

[0030] In the utility model, the baffle plate 1 and the supporting leg 2 are detachably connected through the cooperation of the protrusion 5 and the notch 102. Installing the tool at the reserved hole can not only prevent falling objects from high altitude, but also facilitate passage; at the same time, the movable protrusion 5 can realize the quick installation and disassembly of the tool, and it does not take up space after disassembly, which is convenient for storage; of course, selecting baffle plates 1 with different hole positions to adapt to holes of different calibers can improve the versatility of the tool.

[0031] like Figure 3As shown, in one embodiment, the support leg 2 is provided with an annular groove 3, and the collar 4 is sleeved in the annular groove 3. Specifically, in order to specify the rotation path and sliding distance of the collar 4, this embodiment provides an annular groove 3 on the surface of the support leg 2, and the annular groove 3 is used to avoid the collar 4, so that the collar 4 can slide and rotate in the annular groove 3, that is, the width of the annular groove 3 is greater than the width of the collar 4, and the diameter of the annular groove 3 is smaller than the diameter of the collar 4, so as to prevent the protrusion 5 from completely sinking into the notch 102 without a fulcrum.

[0032] Furthermore, in one embodiment, a spring 6 is sleeved in the annular groove 3, and the spring 6 supports the collar 4, so that in the staggered state, the collar 4 at least partially protrudes out of the corresponding through hole 101. Specifically, in order to enable the protrusion 5 to rotate above the baffle 1, this embodiment sleeves the spring 6 on the support leg 2, and the spring 6 is located in the annular groove 3 and is used to support the collar 4, so that the protrusion 5 can stay above the baffle 1 in the staggered state.

[0033] like Figure 2 As shown, in one embodiment, each of the via holes 101 is arranged near the corresponding vertex corner of the baffle 1. Specifically, in order to improve the stability of the baffle 1, this embodiment arranges each of the via holes 101 near the corresponding vertex corner of the baffle 1 so that the force on the baffle 1 is balanced and the support leg 2 is also convenient for abutting against the inner wall of the reserved hole. In other embodiments, if the reserved hole is circular, the baffle 1 can also choose the same circular structure, and the via holes 101 can be arranged near the edge of the baffle 1; or the baffle 1 with a rectangular structure as in this embodiment can also be used.

[0034] like Figure 1 , Figure 2 As shown, in one embodiment, two adjacent support legs 2 are connected by a connecting rod. Specifically, in order to improve the stability of each support leg 2, this embodiment arranges a connecting rod between two adjacent support legs 2, that is, the support legs 2 and the connecting rod are staggered and enclosed to form a closed cavity for contacting with the inner wall of the reserved hole.

[0035] Furthermore, in one embodiment, the connecting rod includes a first connecting section 7 and a second connecting section 8 respectively provided on two adjacent supporting legs 2, and a threaded section 9 connecting the first connecting section 7 and the second connecting section 8. Specifically, in order to fix each supporting leg 2 to the inner wall of the reserved hole, the connecting rod includes a first connecting section 7, a threaded section 9 and a second connecting section 8 connected in sequence, and the elongation or retraction of the threaded section 9 is changed to change the spacing between the two adjacent supporting legs 2. During installation, the supporting legs 2 can be abutted against the inner wall of the reserved hole by adjusting the connecting rod, further preventing the baffle 1 from shifting; on the other hand, changing the spacing between the two adjacent supporting legs 2 can also adapt to the installation requirements of different calibers, and combined with the replaceable baffle 1, the versatility of the tool is improved. Of course, the number of through holes 101 can be in multiples with the number of supporting legs 2, and the support legs 2 can also be inserted into the through holes 101 at different positions.

[0036] When in use, the position of each support leg 2 at the reserved hole is adjusted by the connecting rod until the two are in contact, and then each support leg 2 is inserted into the corresponding through hole 101, and finally the protrusion 5 is rotated to be offset from the notch 102.

[0037] like Figure 1-Figure 3 As shown, in one embodiment, the support leg 2 is arranged in the up-down direction, and a positioning column 10 extending in the left-right direction is arranged at the lower end thereof. Specifically, in order to position the support leg 2, the present embodiment arranges a positioning column 10 at the lower end of the support leg 2, and the positioning column 10 and the support leg 2 together form an L-shaped structure, which is used to be clamped on the floor, and the tool is fixed at the reserved hole with the floor as a reference.

[0038] Preferably, the outer surface of the supporting leg 2 is provided with a friction layer to increase the friction between the supporting leg 2 and the inner wall of the floor / reserved opening.

[0039] Preferably, the baffle plate 1 is provided with a sealing gasket (not shown). In the staggered state, the sealing gasket is pressed between the baffle plate 1 and the reserved hole to achieve the purpose of waterproofing and reduce the risk of water seepage.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
