Description

Technical Field

[0001] This utility model relates to the field of building fire protection tools, specifically a height adjustment structure and measuring device for building fire protection. Background Technology

[0002] Measuring instruments generally refer to tools or equipment used to measure physical quantities, which can include basic physical quantities such as length, mass, time, temperature, electric current, and amount of matter. In the field of building fire protection, fire hydrant boxes are an important component of the fixed fire extinguishing system inside a building, mainly used to store and protect fire-fighting equipment so that it can be quickly accessed in the event of a fire.

[0003] Precise height measurement is essential when installing fire hydrant boxes, as their installation height directly affects the usability, ease of operation, and fire extinguishing efficiency of fire protection facilities. However, in actual construction, due to factors such as terrain undulations, decoration errors, or building structural deviations, the actual installation position of the fire hydrant box often deviates from the design requirements, necessitating a re-measurement and adjustment of the height.

[0004] Especially when fire hydrant boxes need to be installed on uneven ground such as slopes, the height of the two ends of the box from the ground is inconsistent, which increases the difficulty of measurement. In order to ensure the levelness, it is necessary to repeatedly compare and measure on the left and right sides. At the same time, the stability of the box must be taken into account to prevent tilting or displacement. This process is not only cumbersome and time-consuming, but also brings great inconvenience to on-site construction. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a height adjustment structure and measuring device for building fire protection, which can achieve leveling more quickly, and the fire hydrant box will not tilt or shift during the leveling process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable structure for building fire protection, comprising a base plate located below a fire hydrant box, with external columns fixedly connected to both ends of the upper surface of the base plate, each external column having a lifting chamber inside, a T-shaped opening at the upper end of each external column, a T-shaped ring rotatably connected inside each T-shaped opening, a knob fixedly connected to one end of each T-shaped ring at the T-shaped opening, threaded rods threadedly connected to the inner walls of each knob, the lower ends of each threaded rod being located within the lifting chamber, and the upper ends of each threaded rod being connected to the bottom of the fire hydrant box.

[0007] Furthermore, anti-detachment blocks are fixedly connected to one end of each of the two threaded rods located inside the lifting cavity.

[0008] Furthermore, the two threaded rods are simultaneously fixedly connected to an upper plate at one end near the fire hydrant box, with the upper surface of the upper plate abutting against the bottom surface of the fire hydrant box.

[0009] Furthermore, the upper plate is fastened to the fire hydrant box by bolts.

[0010] Furthermore, a connecting rod is fixedly connected to the middle of the bottom surface of the upper plate, and a lower plate is fixedly connected to the lower end of the connecting rod. The two ends of the lower plate are respectively sleeved and slidably connected to the outer walls of the two outer columns.

[0011] Furthermore, a bubble level is fixedly connected to the front side of the upper plate.

[0012] This utility model also provides a measuring device, including the above-mentioned height adjustment structure for building fire protection, wherein a set of scale lines is provided on the outer wall of each of the two outer columns, and the two sets of scale lines are respectively aligned with the two ends of the lower plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of height adjustment structure and measuring device for fire protection in buildings can adapt to slightly concave or uneven ground by setting a base plate. For sloping or raised ground, it is only necessary to raise the lower side of the base plate, without the need for complicated adjustments to the fire hydrant box itself.

[0015] This type of height adjustment structure and measuring device for building fire protection can monitor the level of the fire hydrant box in real time and intuitively through the bubble level on the front side of the upper plate, eliminating the need for repeated manual measurement and comparison, and greatly improving installation efficiency;

[0016] This type of height adjustment structure and measuring device for building fire protection has its upper plate bolted to the fire hydrant box. After the height adjustment is completed and the box is fixed, the adjustment structure can be easily separated without affecting the subsequent wall fixing process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-3 A height-adjustable structure for building fire protection includes a base plate 2 located below a fire hydrant box 1. Both ends of the upper surface of the base plate 2 are fixedly connected to outer columns 3. Each of the two outer columns 3 has a lifting cavity 302. The upper end of each of the two outer columns 3 has a T-shaped opening 303. A T-shaped ring 8 is rotatably connected inside each of the two T-shaped rings 303. A knob 7 is fixedly connected to one end of each of the two T-shaped rings 8 located at the T-shaped opening 303. Threaded rods 10 are threadedly connected to the inner walls of each of the two knobs 7. The lower ends of each of the two threaded rods 10 are located inside the lifting cavity 302, and the upper ends of each of the two threaded rods 10 are connected to the bottom of the fire hydrant box 1.

[0023] like Figures 1 to 3 As shown, when using the height adjustment structure for building fire protection in this utility model, simply place the base plate 2 flat on the ground. If the ground is only slightly concave or has pits, the planar support of the base plate 2 will not affect the vertical support of the two outer columns 3. However, if the ground is raised or sloping, the base plate 2 will be in an overall tilted state when placed on the ground. Therefore, the fire hydrant box 1 will remain parallel to the base plate 2. At this time, it is only necessary to measure the height and then raise the side of the base plate 2 that is touching the ground. There is no need to measure repeatedly, and the fire hydrant box 1 will not tilt or shift during the adjustment.

[0024] If the height of the fire hydrant box 1 is lower or higher than the standard, simply turn the two knobs 7. The two knobs 7 can rotate inside the T-shaped opening 303 through the T-shaped ring 8. During the rotation of the knobs 7, because the lower end of the outer column 3 and the upper end of the threaded rod 10 are fixed and limited by the base plate 2 and the fire hydrant box 1 respectively, the threaded rod 10 will gradually rise or fall from the lifting cavity 302 of the outer column 3 as the knobs 7 are turned, thereby adjusting the fire hydrant box 1 to a suitable height.

[0025] As a preferred embodiment of this utility model, one end of each of the two threaded rods 10 located in the lifting cavity 302 is fixedly connected with an anti-detachment block 9.

[0026] More specifically, by setting the anti-detachment block 9, the threaded rod 10 can be prevented from falling out of the lifting cavity 302.

[0027] As a preferred embodiment of this utility model, the two threaded rods 10 are simultaneously fixedly connected to an upper plate 6 at one end near the fire hydrant box 1, and the upper surface of the upper plate 6 abuts against the bottom surface of the fire hydrant box 1.

[0028] More specifically, by setting the upper plate 6, the support effect and stability between the two threaded rods 10 and the fire hydrant box 1 can be improved.

[0029] As a preferred embodiment of this utility model, the upper plate 6 is fastened to the fire hydrant box 1 by bolts.

[0030] More specifically, by setting bolt connections, the adjustment structure in this utility model can be separated after the fire hydrant box 1 has been adjusted and is stably fixed to the wall.

[0031] As a preferred embodiment of this utility model, a connecting rod 5 is fixedly connected to the middle of the bottom surface of the upper plate 6, and a lower plate 4 is fixedly connected to the lower end of the connecting rod 5. The two ends of the lower plate 4 are respectively sleeved and slidably connected to the outer walls of the two outer columns 3.

[0032] More specifically, by connecting a lower plate 4 to the lower part of the upper plate 6 via a connecting rod 5, and connecting the lower plate 4 to the two outer columns 3, an additional connection can be added between the two outer columns 3 through the lower plate 4, thereby improving the lateral strength.

[0033] As a preferred embodiment of this utility model, a bubble level 11 is fixedly connected to the front side of the upper plate 6.

[0034] More specifically, by setting up a bubble level 11, it is possible to know in real time and intuitively whether the fire hydrant box 1 is tilted.

[0035] This utility model also provides a measuring device, including the above-mentioned height adjustment structure for building fire protection, wherein a set of scale lines 301 are provided on the outer walls of the two outer columns 3, and the two sets of scale lines 301 are respectively aligned with the two ends of the lower plate 4.

[0036] More specifically, by setting the scale line 301, when adjusting the lower plate 4, one can clearly understand the current height by observing the indication of the lower plate 4 and the scale line 301, which is more convenient.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
