Technical Field

[0001] This utility model is a recording device for engineering cost, belonging to the field of engineering cost recording equipment. Background Technology

[0002] Construction cost recording devices typically refer to devices used to record and manage various expenses and costs during the construction process of a construction project. These devices help project managers to neatly display cost records and assist them in the orderly settlement of construction costs, ensuring that the project proceeds smoothly within the budget.

[0003] In the existing technology, the recording surface of the existing engineering cost recording device is a plate, and the paper report is fixed to the plate by magnetic attraction. When the device is used outdoors, it cannot be protected from wind, dust and water. Moreover, when the management personnel pass by the recording device, external objects can easily scratch the paper report, resulting in damage to the cost report and reducing the efficiency of engineering cost recording.

[0004] In summary, this utility model provides a device for recording engineering costs to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a recording device for engineering cost, so as to solve the problem mentioned in the background technology that paper reports cannot be effectively protected, the cost reports are easily damaged by accidents, and the efficiency of engineering cost is reduced.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a recording device for engineering costs, comprising a display frame, a display window on the front of the display frame, a magnetic plate embedded in the back of the inner wall of the display window, lighting strips fixedly installed at the top and bottom of the inner wall of the display window, a waterproof curtain fixedly connected to the top of the display frame, three clips evenly embedded from left to right on the front of the display frame and below the display window, each clip being covered with a rubber sleeve, and a ring fixedly connected to the front end of each clip, and mounting bases fixedly connected to the top and bottom of both sides of the display frame.

[0007] Furthermore, each mounting base has a threaded hole on its front side, the rubber sleeve is hollow and elliptical, and the locking rod is engaged with the display frame through the rubber sleeve.

[0008] Furthermore, the waterproof curtain includes a mounting box, which is fixedly connected to the top of the display frame. A mounting shaft is rotatably connected between the two sides of the inner wall of the mounting box. A rubber curtain is wound around the shaft surface of the mounting shaft, which is directly above the display window. Coil springs are wound around both sides of the shaft surface of the mounting shaft. One end of each of the two coil springs extends to the bottom of the inner wall of the mounting box. One end of the rubber curtain passes through the front side of the bottom of the inner wall of the mounting box and extends to the bottom of the mounting box. A limit strip is fixedly connected to one end of the rubber curtain, which is located at the top of the front of the display frame. Pull rods are rotatably connected to both sides of the bottom of the limit strip.

[0009] Furthermore, the limiting strip is attached to the display frame, and the rubber curtain is in contact with the mounting box.

[0010] Furthermore, the other end of the coil spring is fixedly connected to the axial surface of the mounting shaft, and the other end of the rubber curtain is fixedly connected to the axial surface of the mounting shaft.

[0011] Furthermore, the front of the limiting strip is evenly provided with multiple through holes from left to right for the connecting rods to pass through, and both of the pull rods are bent at right angles.

[0012] The beneficial effects of this utility model are:

[0013] Pull the limiting strip down with the lever and pull the rubber curtain out of the mounting box. Align the locking rod with the locking hole and through hole and insert it. The rubber sleeve completes the reinforcement connection between the locking rod and the limiting strip and the display frame. The display window can then be quickly closed by unfolding the rubber curtain. The rubber curtain is made of white transparent rubber and will not affect the normal display of the project cost record report inside the display window. It can protect the project cost record report from wind, dust and water, thus improving the efficiency of project cost estimation.

[0014] Pull out the lever by the ring to release the limiting strip from the display frame. Then rotate each lever 180° so that the bent end of the lever is no longer engaged with the bottom of the display frame. Release the lever, and the spring's rebound force will cause the mounting shaft to reverse, allowing the rubber curtain to be rolled up and stored. This effectively saves space occupied during the opening or closing of the construction cost recording device, reduces the space required for installation and use, and improves the ease of use of the construction cost recording device.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a recording device for engineering cost, including a display frame 1, a display window 2 on the front of the display frame 1, and a magnetic plate 3 embedded in the back of the inner wall of the display window 2. The magnetic plate 3 is made of magnetic material, which facilitates connection or fixation with other objects with metal or magnetic materials. The engineering cost record sheet can be clamped and fixed between the metal block and the magnetic plate 3 by magnetically attracting an external metal block. Lighting strips 4 are fixedly installed at the top and bottom of the inner wall of the display window 2. Both lighting strips 4 are connected to an external power source and are equipped with power control switches. The lighting strips 4 can clearly display the engineering cost record sheet fixed inside the display window 2. As shown, a waterproof curtain 5 is fixedly connected to the top of the display frame 1. Three locking rods 6 are evenly embedded from left to right on the front of the display frame 1 and below the display window 2. Each locking rod 6 is covered with a rubber sleeve 7. A ring 8 is fixedly connected to the front end of each locking rod 6. Mounting seats 9 are fixedly connected to the top and bottom of both sides of the display frame 1. The ring 8 makes it easy to pull the locking rods 6 and perform the locking operation between the locking rods 6 and the display frame 1. Each mounting seat 9 has a threaded hole on its front. The rubber sleeve 7 is hollow and elliptical. The locking rods 6 are locked to the display frame 1 through the rubber sleeve 7. The device can be fixedly installed on the wall by using the threaded hole on the mounting seat 9 in conjunction with the external bolt.

[0025] Please see Figure 2-6 The waterproof curtain 5 includes a mounting box 51, which is fixedly connected to the top of the display frame 1. A mounting shaft 52 is rotatably connected between the two sides of the inner wall of the mounting box 51. A rubber curtain 54 is wound around the shaft surface of the mounting shaft 52, directly above the display window 2. Coil springs 53 are wound around both sides of the shaft surface of the mounting shaft 52, with one end of each coil spring 53 extending to the bottom of the inner wall of the mounting box 51. One end of the rubber curtain 54 passes through the front side of the bottom of the inner wall of the mounting box 51 and extends to the bottom of the mounting box 51. A limit strip 55 is fixedly connected to one end of the rubber curtain 54, located at the top of the front of the display frame 1. Pull rods 56 are rotatably connected to both sides of the bottom of the limit strip 55. The limit strip 55 is in contact with the display frame 1, and the rubber curtain 54 is in contact with the mounting box 51. The coil springs 53... The other end is fixedly connected to the shaft surface of the mounting shaft 52. When the limit strip 55 is pulled down by the pull rod 56 and the rubber curtain 54 is pulled out from the inside of the mounting box 51, the rubber curtain 54 is made of white transparent rubber. The rubber curtain 54 can drive the mounting shaft 52 to rotate inside the mounting box 51. The mounting shaft 52 simultaneously drives the two coil springs 53 to unwind and deform. When the limit strip 55 is released, the coil springs 53 can elastically deform and reset, thereby driving the mounting shaft 52 to reverse, so that the rubber curtain 54 can be rolled up and stored. The width of the rubber curtain 54 is greater than the width of the display window 2. After being pulled out from the inside of the mounting box 51, the back of the rubber curtain 54 can fit against the front of the display frame 1.

[0026] Please see Figure 2-6 The front of the limiting strip 55 has multiple through holes evenly spaced from left to right to accommodate the locking rod 6. The width of the limiting strip 55 is greater than the width of the rubber curtain 54, thus limiting the rubber curtain 54 and preventing excessive rebound force of the coil spring 53, which could cause the rubber curtain 54 to be completely rolled into the installation box 51. Both pull rods 56 are bent at right angles. The bottom of the front of the display frame 1 has locking holes for engaging the locking rod 6. When the pull rod 56 is pulled down, the bent end of the pull rod 56 is positioned below the display frame 1. Rotating the pull rod 56 180° causes the bent end of the pull rod 56 to fit against the bottom of the display frame 1, thereby quickly fixing and unfolding the pulled-out rubber curtain 54. The through holes on the limiting strip 55 are aligned with the locking holes at the bottom of the front of the display frame 1, allowing the locking rod 6 to be aligned with the locking holes and through holes and inserted, completing the reinforced connection between the limiting strip 55 and the display frame 1.

[0027] Detailed implementation: The magnetic plate 3 is made of magnetic material, which makes it easy to connect or fix with other objects with metal or magnetic materials. The project cost record sheet can be clamped and fixed between the metal block and the magnetic plate 3 by magnetically attracting the external metal block. The project cost sheet can be displayed and recorded through the display window 2.

[0028] When the recording device is installed outdoors, the limit strip 55 can be pulled down by the pull rod 56 to pull the rubber curtain 54 out of the mounting box 51. The rubber curtain 54 can drive the mounting shaft 52 to rotate inside the mounting box 51. The mounting shaft 52 simultaneously drives the two coil springs 53 to unwind and deform, pulling the bent end of the pull rod 56 to the bottom of the display frame 1. Rotating the pull rod 56 180° makes the bent end of the pull rod 56 fit against the bottom of the display frame 1, thereby quickly pulling out the rubber curtain 54. Once the fixed extension is completed and the through hole on the limiting strip 55 is aligned with the card hole at the bottom front of the display frame 1, the card rod 6 can be aligned with the card hole and the through hole and inserted. The card rod 6 completes the reinforcement connection between the limiting strip 55 and the display frame 1 through the rubber sleeve 7. Thus, the display window 2 can be quickly closed through the unfolded rubber curtain 54. The rubber curtain 54 is made of white transparent rubber and will not affect the normal display of the engineering cost record report inside the display window 2. It can protect the engineering cost record report from wind, dust and water.

[0029] When it is necessary to open the display window 2 to replace or adjust the project cost record sheet, the locking rod 6 can be pulled out directly through the ring 8 to release the fixing strip 55 from the display frame 1. Then, rotate each pull rod 56 180° so that the bent end of the pull rod 56 is no longer locked to the bottom of the display frame 1. Release the pull rod 56, and the rebound force of the coil spring 53 can drive the mounting shaft 52 to reverse, so that the rubber curtain 54 can be rolled up and stored. This effectively saves the space occupied by the opening or closing operation of the project cost record device, saves the space required for the installation and use of the project cost record device, and improves the convenience of using the project cost record device.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
