Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, and more specifically to a stable protection mechanism for indoor fire hydrants. Background Art

[0002] The stable protection mechanism of indoor fire hydrants refers to a series of designs that ensure that fire hydrants remain closed when not in use to prevent accidental opening, and can provide stable and safe water supply when in use. These mechanisms ensure the reliability and safety of fire-fighting facilities;

[0003] Generally, a locking device can be provided: through a structural component that prevents arbitrary opening, it is possible to prevent unauthorized personnel from opening and using it at will, so as to ensure that the fire hydrant remains closed and sealed in non-emergency situations (as shown in the publication (publication) number: CN220957066U, a fire hydrant valve);

[0004] The above-mentioned "fire hydrant valve" adopts a "fixed component" as a locking component to limit the rotation of the "turntable". This structure is too intuitive, that is, it is easy to be loosened by operation, and has the disadvantage of low limiting ability to prevent arbitrary opening. Utility Model Content

[0005] The purpose of the utility model is to solve the above technical problems and provide an indoor fire hydrant stabilization protection mechanism.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model proposes an indoor fire hydrant stable protection mechanism, comprising a hydrant body, a valve stem arranged on the hydrant body and a hand wheel arranged outside the hydrant body;

[0008] It also includes a through port provided on the hand wheel, the through port being rotatably connected to the valve stem;

[0009] A fastening assembly for fastening the hand wheel and the valve stem is provided between the valve stem and the through port, so that the valve stem can be rotated by rotating the hand wheel.

[0010] The fixed connection component includes a connecting disk connected to the internal thread of the through port, a rotating plate and a connecting block fixed outside the connecting disk, and a connecting groove connected to the connecting block thread. The rotating plate is located outside the through port, the connecting groove is arranged on the valve stem, and the connection depth between the connecting block and the connecting groove is less than the connection depth between the connecting disk and the through port.

[0011] As a preferred technical solution of the utility model, the rotating plate is provided with anti-slip grooves on the outside.

[0012] As a preferred technical solution of the utility model, a positioning component for blocking the rotation of the hand wheel is provided on the bolt body and the hand wheel.

[0013] As a preferred technical solution of the utility model, the positioning assembly includes an insertion rod, a grip rod fixed to one end of the insertion rod, and a stable through hole and a slot for the other end of the insertion rod to be inserted in sequence. The through hole is arranged on the hand wheel and the slot is arranged on the bolt body.

[0014] As a preferred technical solution of the utility model, the outside of the grip is fixedly provided with anti-slip grooves.

[0015] The beneficial effects of the utility model are as follows:

[0016] By setting a through port 4 on the hand wheel 3 and rotatably connecting it with the valve stem 2, a fixing component 5 is used therebetween to separate and connect the valve stem 2 and the hand wheel 3. The rotation of the rotating plate 52 can drive the connecting disk 51 to be screwed into the through port 4, and drive the connecting block 53 to be screwed into the connecting groove 54. At this time, rotating the hand wheel 3 can drive the valve stem 2 to rotate, which is easy to operate. After the connecting groove 54 rotates out of the connecting block 53, the connecting disk 51 is still connected to the through port 4 to form an integrated shape. However, when the hand wheel 3 is rotated, the valve stem 2 can no longer be driven to rotate. It is well concealed and not easy to be operated to open. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure numerals: bolt body -1, valve stem -2, hand wheel -3, port -4, fixing assembly -5, positioning assembly -6, connecting plate -51, rotating plate -52, connecting block -53, connecting groove -54, insert rod -61, grip rod -62, through hole -63, slot -64. DETAILED DESCRIPTION Embodiment 1:

[0019] like Figure 1 As shown, this embodiment proposes: an indoor fire hydrant stable protection mechanism, comprising a bolt body 1, a valve stem 2 arranged on the bolt body 1, and a hand wheel 3 arranged outside the bolt body 1 (the bolt body 1 is a fire hydrant opened and closed by rotating the hand wheel);

[0020] It also includes a through-port 4 provided on the hand wheel 3, and the through-port 4 is rotatably connected with the valve stem 2 (as shown in the figure, the through-port 4 is formed through the center of the top and bottom ends of the hand wheel 3, and a ring-shaped rotating member is adopted at the lower part of the inner wall of the through-port 4, and the ring-shaped rotating member can be a rolling bearing, such as a deep groove ball bearing, etc.);

[0021] A fastening assembly 5 for fastening the hand wheel 3 and the valve stem 2 is provided between the valve stem 2 and the opening 4, so that the valve stem 2 can be rotated by rotating the hand wheel 3;

[0022] In order to implement the above-mentioned fixed connection component 5, it is proposed that Figure 1As shown, the specific structure and composition of the fixed connection component 5 can be as follows: the fixed connection component 5 includes a connecting plate 51 connected to the inner thread of the through port 4 (as shown in the figure, the inner space on the rotating part inside the through port 4 is threadedly connected to the connecting plate 51);

[0023] The rotating plate 52 and the connecting block 53 are fixed to the outside of the connecting plate 51 (as shown in the figure, the rotating plate 52 and the connecting block 53 are respectively fixed to the top and bottom ends of the connecting plate 51, and can be integrally formed or welded);

[0024] The connecting groove 54 is threadedly connected to the connecting block 53, and the rotating plate 52 is located outside the through port 4. The connecting groove 54 is arranged on the valve stem 2 (as shown in the figure, the connecting groove 54 is arranged in the center of the top end of the valve stem 2). When the connecting plate 51 rotates, the connecting block 53 can be driven to rotate into the connecting groove 54. At this time, the valve stem 2 can be driven to rotate by rotating the hand wheel 3, which is easy to operate.

[0025] The connection depth between the connecting block 53 and the connecting groove 54 is less than the connection depth between the connecting disk 51 and the passage 4 (as shown in the figure, that is, the height of the connecting disk 51 moving downward in the passage 4 is greater than the height of the connecting block 53 moving downward in the connecting groove 54), so that during the operation, when the connecting block 53 falls off the connecting groove 54, the connecting disk 51 can still be stably threadedly connected to the passage 4 to form an integrated shape, but when the hand wheel 3 is rotated, it can no longer drive the valve stem 2 to rotate, and it is well concealed and not easy to be operated to open.

[0026] The rotating plate 52 is provided with anti-skid grooves on its outer surface to increase the friction force on the surface of the rotating plate 52 to help the rotating plate 52 to be grasped and rotated. Embodiment 2:

[0027] like Figure 1 As shown, the difference from Example 1 is that: it also includes that the bolt body 1 and the hand wheel 3 are provided with a positioning component 6 for blocking the rotation of the hand wheel 3, and a component for blocking the rotation of the hand wheel 3 is additionally provided to improve the anti-rotation capability of the hand wheel 3.

[0028] In order to implement the above positioning component 6, it is proposed that Figure 1 As shown, the specific structure and composition of the positioning component 6 can be as follows: the positioning component 6 includes an insertion rod 61, a gripping rod 62 fixed to one end of the insertion rod 61, and a through hole 63 and a slot 64 for the other end of the insertion rod 61 to be inserted into a stable state in sequence, the through hole 63 is arranged on the hand wheel 3, and the slot 64 is arranged on the bolt body 1 (as shown in the figure, it can be: the through hole 63 passes through the top and bottom ends of the hand wheel 3, and the slot 64 is formed by being sunken from top to bottom at the top of the bolt body 1, and the gripping rod 62 is held to insert the insertion rod 61 through the through hole 63 and then into the slot 64, so as to stabilize the hand wheel 3 and limit the rotation of the hand wheel 3).

[0029] The grip 62 is provided with anti-slip grooves on its outer surface to increase the friction force on the grip 62 surface, so as to assist the grip 62 in rotating operation;

[0030] Supplementary: After the position of the hand wheel 3 is stabilized, the above-mentioned rotating plate 52 can be rotated more conveniently. At the same time, the corresponding positions of the threads of the connecting groove 54 and the through-port 4 can also be positioned and limited, so that when the connecting plate 51 rotates in the through-port 4, it can continuously drive the connecting block 53 to rotate and connect in the connecting groove 54, thereby facilitating the ease of operation.

[0031] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
