[0025] The front of the full text is Figure 1 In the direction indicated by the arrow.

[0026] See also Figures 1 to 6Now, the fire hydrant box for clean room provided by the utility model is described. A fire hydrant box for a clean room includes a box body 10, two guide rods 20, a box door 30, a lock plug-in 40 and a drive member 50. The box body 10 has a forward opening, and a locking groove 11 is provided on the inner side wall of the box body 10; the two guide rods 20 are arranged in the box body 10 and are respectively arranged near the two opposite inner side walls of the box body 10, and the guide rods 20 extend in the up and down directions; the box door 30 is arranged at the front side of the box body 10 and is used to block the opening of the box body 10, and a sliding sleeve 31 is provided on the inner side wall of the box door 30, which is slidably sleeved on the outer periphery of the guide rod 20, and a sliding groove 32 is provided on one side edge of the box door 30 close to the locking groove 11, which is arranged opposite to the locking groove 11, and the sliding groove 32 extends in the horizontal direction; the lock plug-in 40 is slidably connected in the sliding groove 32, and is used to be plugged into and cooperated with the locking groove 11 to lock the position of the box door 30; the drive member 50 is arranged on the box door 30 and is used to drive the lock plug-in 40.

[0027] The embodiment of the present application provides a fire hydrant box for a clean room. During its actual use, it is only necessary to drive the driving member 50 to drive the lock plug 40 to disengage the locking groove 11, and slide the box door 30 downward to avoid the opening of the box body 10, thereby avoiding the restricted opening of the box door 30 in a narrow space, making it convenient to take water from the fire hydrant to extinguish the fire, and eliminating safety hazards.

[0028] When the door 30 needs to be closed, the driving member 50 is first driven to drive the lock plug-in 40 to retract into the sliding groove 32, and then the door 30 is slid upward until the lock plug-in 40 is aligned with the locking groove 11. Finally, the driving member 50 is driven to drive the lock plug-in 40 to insert into the locking groove 11, and the door 30 can be quickly closed.

[0029] Compared with the prior art, the fire hydrant box for a clean room provided in this embodiment drives the lock plug 40 out of the locking groove 11 by driving the driving member 50, and slides the box door 30 downward to avoid the opening of the box body 10, thereby avoiding the restricted opening of the box door 30 in a narrow space, facilitating the use of water for fire extinguishing in the fire hydrant, and eliminating safety hazards.

[0030] In a possible implementation, the door 30 is Figure 1 and Figure 6 The structure shown, see Figure 1 and Figure 6 The box door 30 is provided with a connecting cavity 33 connected to the sliding groove 32, the lock plug 40 is a rack, and the driving member 50 includes a gear 52 and a knob 51. The gear 52 is rotatably connected to the connecting cavity 33 and meshes with the rack; the knob 51 is rotatably connected to the front side wall of the box door 30 and extends into the connecting cavity 33. The extended end of the knob 51 is connected to the gear 52.

[0031] Specifically, the communication cavity 33 is located above or below the sliding groove 32 , and the extended end of the rack has no teeth. The transmission of the gear 52 and the rack facilitates the connection between the rack and the locking groove 11 .

[0032] When the rack needs to be driven to move, it is only necessary to rotate the knob 51 so that the knob 51 drives the gear 52 to rotate, and the rack is driven to move under the rotation of the gear 52. The driving principle of the gear 52 and the rack is relatively stable, which improves the stability of the rack movement.

[0033] In some embodiments, see Figure 1 and Figure 6 Two sliding grooves 32 are provided at intervals along the up and down directions, and the opening directions are opposite. Locking grooves 11 are provided on the two opposite inner walls of the box body 10. The two locking grooves 11 are arranged in a one-to-one correspondence with the two sliding grooves 32. The connecting cavity 33 is located between the two sliding grooves 32 and is respectively connected to the two sliding grooves 32. Two racks are provided, and are respectively arranged in a one-to-one correspondence with the two sliding grooves 32. The gear 52 is engaged with the two racks respectively, and is used to drive the two racks to move toward or away from each other.

[0034] Specifically, a gear 52 is used to simultaneously drive the two racks to move in opposite directions and to be plugged and locked into the two locking grooves 11 one by one, or to drive the two racks to move toward each other and disengage from the locking grooves 11, thereby further improving the connection stability between the door 30 and the box body 10 without increasing the operating steps.

[0035] In some embodiments, see Figure 6 A first elastic member 60 extending toward the open end of the sliding groove 32 is connected to the inner bottom wall of the sliding groove 32. The extended end of the first elastic member 60 is connected to the inner end of the rack. The first elastic member 60 can elastically push the rack to be inserted into the locking groove 11.

[0036] Specifically, through the elastic pushing action of the first elastic member 60, the rack can be elastically inserted into the locking groove 11, that is, the rack can be automatically inserted into the locking groove 11 without turning the knob 51. When unlocking, it is only necessary to rotate the knob 51 to move the two racks toward each other and out of the locking groove 11, thereby improving practicality.

[0037] In some embodiments, see Figure 1 and Figures 3 to 5 A slot 34 is provided on the front side wall of the box door 30 , and a sealing cap 70 is provided on the knob 51 . The sealing cap 70 is provided with an inserting platform 71 which is plugged into and matched with the slot 34 .

[0038] Specifically, the sealing cap 70 is used to cover the knob 51 , and the insertion of the insert 71 and the slot 34 is used to limit the rotation of the sealing cap 70 , thereby preventing others from accidentally touching the knob 51 and causing the door 30 to open.

[0039] When the door 30 needs to be opened, the sealing cap 70 only needs to be pulled outward and the knob 51 rotated.

[0040] In some embodiments, see Figure 1 A magnet 80 for adsorbing the inserting platform 71 is provided on the inner bottom wall of the slot 34 .

[0041] Specifically, the magnet 80 adsorbs the inserting platform 71 , so that the inserting platform 71 is stably inserted into the slot 34 , thereby preventing the sealing cap 70 from accidentally falling off.

[0042] In some embodiments, see Figure 1 Two slots 34 are provided at intervals along the up-down direction, and the slots 34 are located on the side of the sliding groove 32 away from the communicating cavity 33 .

[0043] Specifically, the slot 34 is arranged at a position that completely avoids the sliding groove 32 and the connecting cavity 33 , thereby preventing the insertion of the inserting platform 71 into the slot 34 from affecting the use of the knob 51 and the lock plug 40 .

[0044] In a possible implementation, the guide rod 20 is Figure 2 The structure shown, see Figure 2 The outer periphery of the guide rod 20 is provided with a second elastic member 90 located between the sliding sleeve 31 and the inner bottom wall of the box body 10 .

[0045] Specifically, the second elastic member 90 is slidably sleeved on the guide rod 20. In a natural state, the second elastic member 90 is located at the lower part of the guide rod 20. When the lock plug 40 is disengaged from the locking groove 11, the box door 30 can be released directly without manual support. The box door 30 falls freely until the sliding sleeve 31 contacts the second elastic member 90, so that the second elastic member 90 cushions it, avoiding a hard collision between the sliding sleeve 31 and the box body 10, and effectively protecting the box body 10 and the box door 30.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
