Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost tools, in particular to an auxiliary inspection tool. Background Art

[0002] Project cost refers to the total cost of a project. Its core content is investment estimation, design budget, revised budget, construction drawing budget, project settlement, completion settlement, etc. The main task of project cost is to calculate the direct costs (labor, materials and equipment, construction machinery and tools), enterprise management fees, measures fees, fees, profits and taxes, etc. included in the project according to drawings, quotas and list specifications. When checking the project cost, it is necessary to check it against the drawings and show it to the staff for review.

[0003] At present, the conventional method is to check the drawings by placing them on a display board. In order to ensure the support stability and convenient movement of the display board, a support rod and a universal wheel are usually set at the bottom of the display board. However, this will increase the overall volume of the display board, making it difficult to store the display board and taking up more space. For this reason, we propose an auxiliary inspection tool. Utility Model Content

[0004] The purpose of the utility model is to provide an auxiliary inspection tool to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: an auxiliary inspection tool, comprising a display board and a bracket, a supporting device is arranged at the bottom of the bracket, the supporting device comprises a fixed block, a support rod, a sleeve and a universal wheel, a fixing member is arranged on the fixed block and the support rod, a limiting member is arranged inside the sleeve and on the support rod, and the limiting member comprises:

[0006] A connecting block, wherein the connecting block is fixed to one end of the support rod away from the fixing block, a connecting spring is fixed to one side of the connecting block close to the bracket, and one end of the connecting spring away from the connecting block is fixed to the inner wall of the sleeve;

[0007] A groove is provided on the top of the connecting block, a clamping knife is slidably mounted on the inner side of the groove, a return spring is fixed on the bottom of the clamping knife, and one end of the return spring away from the clamping knife is fixed on the inner side of the groove;

[0008] An L-shaped rod, the inner wall of the sleeve is fixed with the L-shaped rod, one end of the L-shaped rod away from the sleeve is fixed with a clamping block, the L-shaped rod passes through the slider and is slidably connected with the slider;

[0009] An embedding groove is provided on the side of the block close to the slider, and a spring is fixed to the end of the slider away from the block, and the end of the spring away from the slider is fixed to the L-shaped rod. When the sleeve is pushed to move to the side close to the bracket, the sleeve moves with the L-shaped rod, the block and the slider. When the block moves to the position of the knife, the block contacts the knife to make it move downward. When the block moves to the other side of the knife, the knife pops out and contacts the block under the action of the reset spring, thereby limiting the sleeve and completing the storage of the sleeve.

[0010] Preferably, the fixing block is fixed to the side of the bracket, one end of the support rod is hinged to the fixing block, the other end of the support rod passes through the sleeve and is slidably connected to the sleeve, and a universal wheel is fixed to the bottom of the sleeve.

[0011] Preferably, the display board is connected to the bracket by bolts, and the angle of the display board can be adjusted by loosening the bolts. The drawings of the project cost can be fixed on the display board by magnets for display.

[0012] Preferably, the fixing member includes a push rod, which passes through the connecting block and the support rod and is slidably connected to the connecting block and the support rod, a second spring is fixed on the inner wall of the support rod, one end of the second spring away from the support rod is fixed to the surface of the push rod, a connecting rod is hinged on the inner wall of the support rod, and one end of the support rod close to the fixing block is passed through by a limiting rod and is slidably connected to the limiting rod.

[0013] Preferably, a cam is fixed on the inner side of the fixed block. When the sleeve is pushed to move toward the side close to the fixed block, the sleeve can abut against the push rod, pushing the push rod to retract into the support rod. The push rod can abut against the connecting rod, causing the connecting rod to rotate at the position where it is hinged with the support rod. The connecting rod abuts against the limit rod, pulling the limit rod to retract into the support rod.

[0014] Preferably, the surface of the cam is provided with a first card slot and a second card slot. When the support rod is perpendicular to the bracket, the limit rod can be inserted into the first card slot, thereby limiting the support rod so that the support rod cannot rotate, thereby ensuring the stability of the overall placement of the device; when the support rod is rotated at a position hinged with the fixed block, the support rod moves with the limit rod; when the limit rod is rotated to the protruding part of the cam, the limit rod is resisted and continues to move toward the inner side of the support rod; when the limit rod moves to the position of the second card slot, the limit rod is no longer resisted, and the resisting rod is reset under the action of the second spring, thereby pushing the limit rod to be inserted into the second card slot through the connecting rod, thereby ensuring the stability when the support rod and the sleeve are stored.

[0015] Compared with the prior art, the utility model provides an auxiliary inspection tool with the following beneficial effects:

[0016] 1. This auxiliary inspection tool, through the support equipment, fixing parts and limit parts, when the device needs to be stored as a whole, it only needs to push the sleeve to the side close to the bracket, and then rotate the support rod to keep it flush with the bracket to complete the storage, which is convenient for the staff to store the whole device.

[0017] 2. When the auxiliary inspection tool is needed, just push the sleeve to release the limit of the sleeve, and at the same time rotate the support rod to keep it vertical with the bracket to complete the opening of the supporting equipment, and fix the drawing on the display board with a magnet for display inspection.

[0026] like Figure 1-Figure 7As shown, the utility model provides a technical solution: an auxiliary inspection tool, including a display board 1 and a bracket 2, a supporting device 3 is arranged at the bottom of the bracket 2, the supporting device 3 includes a fixed block 31, a support rod 32, a sleeve 33 and a universal wheel 34, a fixing member 4 is arranged on the fixed block 31 and the support rod 32, a limiting member 5 is arranged inside the sleeve 33 and on the support rod 32, and the limiting member 5 includes: a connecting block 51, a connecting spring 52, a groove 53, a clamping knife 54, a reset spring 55, an L-shaped rod 56, a clamping block 57, a slider 58, an embedding groove 59, and a spring 510.

[0027] A connecting block 51 is fixed to one end of the support rod 32 away from the fixing block 31, a connecting spring 52 is fixed to one side of the connecting block 51 close to the bracket 2, and one end of the connecting spring 52 away from the connecting block 51 is fixed to the inner wall of the sleeve 33, a groove 53 is provided on the top of the connecting block 51, a clamping knife 54 is slidably mounted on the inner side of the groove 53, a return spring 55 is fixed to the bottom of the clamping knife 54, and one end of the return spring 55 away from the clamping knife 54 is fixed to the inner side of the groove 53, an L-shaped rod 56 is fixed to the inner wall of the sleeve 33, and one end of the L-shaped rod 56 away from the sleeve 33 A block 57 is fixed, an L-shaped rod 56 passes through the slider 58 and is slidably connected to the slider 58, an embedding groove 59 is provided on the side of the block 57 close to the slider 58, a spring 510 is fixed to the end of the slider 58 away from the block 57, and the end of the spring 510 away from the slider 58 is fixed to the L-shaped rod 56. When the sleeve 33 is pushed to move to the side close to the bracket 2, the sleeve 33 moves with the L-shaped rod 56, the block 57 and the slider 58. When the block 57 moves to the position of the knife 54, the block 57 contacts the knife 54 to make it move downward. After the block 57 moves to the other side of the knife 54, the knife 54 pops out and abuts on the block 57 under the action of the return spring 55, thereby limiting the sleeve 33 and completing the storage of the sleeve 33. When the sleeve 33 is pushed to move to the side close to the bracket 2 again, the sleeve 33 moves with the L-shaped rod 56, the block 57 and the slider 58. The slider 58 abuts against the knife 54, and the slider 58 pushes the knife 54 downward. When the slider 58 moves to the other side of the knife 54, the knife 54 pops out and abuts on the slider 58. The L-shaped rod 56 is slidably connected. When the sleeve 33 is released, the sleeve 33 moves to the side away from the fixed block 31 under the action of the connecting spring 52. The sleeve 33 moves with the L-shaped rod 56, the block 57 and the slider 58. The knife 54 abuts against the slider 58, causing it to slide on the surface of the L-shaped rod 56. When the slider 58 is embedded in the embedding groove 59 on the block 57, the slider 58 and the block 57 abut against the knife 54, causing the knife 54 to move downward, thereby separating the knife 54 from the slider 58 and the block 57, and releasing the limit on the sleeve 33.

[0028] The fixing block 31 is fixed to the side of the bracket 2, one end of the support rod 32 is hinged to the fixing block 31, the other end of the support rod 32 passes through the sleeve 33 and is slidably connected to the sleeve 33, a universal wheel 34 is fixed to the bottom of the sleeve 33, the display board 1 is connected to the bracket 2 by bolts 6, and the angle of the display board 1 can be adjusted by loosening the bolts 6, and the drawings of the engineering cost can be fixed on the display board 1 by magnets for display and inspection.

[0029] The fixing member 4 includes a push rod 41, which passes through the connecting block 51 and the support rod 32 and is slidably connected with the connecting block 51 and the support rod 32. A spring 2 42 is fixed on the inner wall of the support rod 32, and one end of the spring 2 42 away from the support rod 32 is fixed to the surface of the push rod 41. A connecting rod 43 is hinged on the inner wall of the support rod 32. One end of the support rod 32 close to the fixing block 31 is penetrated by a limit rod 44 and is slidably connected with the limit rod 44. A cam 45 is fixed on the inner side of the fixing block 31. When the sleeve 33 is pushed to move toward the side close to the fixing block 31, the sleeve 33 can abut against the push rod 41, pushing the push rod 41 to retract into the support rod 32, and the push rod 41 can abut against the connecting rod 43, so that the connecting rod 43 rotates at the position hinged with the support rod 32, and the connecting rod 43 abuts against the limit rod 44, pulling the limit rod 44 to retract into the support rod 32.

[0030] A slot 1 451 and a slot 2 452 are provided on the surface of the cam 45. When the support rod 32 is perpendicular to the bracket 2, the limit rod 44 can be inserted into the slot 1 451, thereby limiting the support rod 32 so that the support rod 32 cannot rotate, thereby ensuring the stability of the overall placement of the device. When the support rod 32 is rotated at the position hinged with the fixing block 31, the support rod 32 moves with the limit rod 44. When the limit rod 44 is rotated to the raised part of the cam 45, the limit rod 44 is resisted and continues to move toward the inner side of the support rod 32. When the limit rod 44 moves to the position of the slot 2 452, the limit rod 44 is no longer resisted, and then the resisting rod 41 is reset under the action of the spring 2 42, thereby pushing the limit rod 44 to be inserted into the slot 2 452 through the connecting rod 43, thereby ensuring the stability when the support rod 32 and the sleeve 33 are stored.

[0031] Based on the above embodiment, when the supporting device 3 needs to be stored, the sleeve 33 is pushed to move to the side close to the bracket 2, and the sleeve 33 moves with the L-shaped rod 56, the block 57 and the slider 58. When the block 57 moves to the position of the knife 54, the block 57 abuts against the knife 54 to move it downward. When the block 57 moves to the other side of the knife 54, the knife 54 pops out and abuts against the block 57 under the action of the reset spring 55, thereby limiting the sleeve 33 and completing the storage of the sleeve 33.

[0032] At this time, the sleeve 33 abuts against the abutting rod 41, and the abutting rod 41 retracts into the support rod 32. The abutting rod 41 can abut against the connecting rod 43, so that the connecting rod 43 rotates at the position hinged with the support rod 32. The connecting rod 43 abuts against the limiting rod 44, pulling the limiting rod 44 to retract into the support rod 32, so that the limiting rod 44 withdraws from the slot 451, thereby releasing the limit on the support rod 32.

[0033] The support rod 32 is rotated, and the support rod 32 moves with the limiting rod 44. When the limiting rod 44 is rotated to the raised part of the cam 45, the limiting rod 44 is resisted and continues to move toward the inner side of the support rod 32. When the limiting rod 44 moves to the position of the second card slot 452, the limiting rod 44 is no longer resisted, and then the resisting rod 41 is reset under the action of the second spring 42, so that the limiting rod 44 is pushed to be inserted into the second card slot 452 through the connecting rod 43, thereby ensuring the stability of the support rod 32 and the sleeve 33 when they are stored, completing the storage of the entire device, and making it convenient for the user to place it.

[0034] When it is needed, the sleeve 33 is pushed to move toward the side close to the fixed block 31, and the sleeve 33 moves with the L-shaped rod 56, the block 57 and the slider 58, and the slider 58 contacts the knife 54, and the slider 58 pushes the knife 54 downward. When the slider 58 moves to the other side of the knife 54, the knife 54 pops out and contacts the slider 58. Since the slider 58 is slidably connected with the L-shaped rod 56, when the sleeve 33 is released, the sleeve 33 moves to the side away from the fixed block 31 under the action of the connecting spring 52, and the sleeve 33 moves with the L-shaped rod 56, the block 57 and the slider 58, and the knife 54 contacts the slider 58, so that it slides on the surface of the L-shaped rod 56. When the slider 58 is embedded in the embedding groove 59 on the block 57, the slider 58 and the block 57 contact the knife 54, so that the knife 54 moves downward, thereby separating the knife 54 from the slider 58 and the block 57, and releasing the limit on the sleeve 33.

[0035] When the sleeve 33 is pushed to move toward the side close to the fixed block 31, the sleeve 33 abuts against the abutting rod 41, so that the abutting rod 41 is retracted into the support rod 32 again. The abutting rod 41 abuts against the connecting rod 43, so that the limiting rod 44 is retracted into the support rod 32 and withdraws from the second card slot 452. The support rod 32 is rotated so that the support rod 32 is rotated to a state perpendicular to the bracket 2. The sleeve 33 is released. Under the action of the connecting spring 52, the sleeve 33 pops out. The sleeve 33 no longer abuts against the abutting rod 41. Under the action of the second spring 42, the abutting rod 41 is reset, so that the limiting rod 44 is reset and inserted into the first card slot 451, thereby ensuring the stability of the overall placement of the device. The angle of the display board 1 can be adjusted by loosening the bolt 6, and the drawings of the engineering cost can be fixed on the display board 1 by magnets for display.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
