DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5As shown, a budget result display board includes a base 1, a fixing plate 2 is bolted to one side of the top of the base 1, and the fixing plate 2 can display the cost budget to people. An air inlet groove 3 is opened on the surface of the fixing plate 2. The number of the air inlet grooves 3 is several and they are symmetrically designed with the central axis of the fixing plate 2. With the increase in the number, budget poster boards of different sizes can be fixed on the surface of the fixing plate 2, and there is no need for staff to replace the display board, thereby increasing the practical effect of the display board. A fixing shell 4 is fixed to the inner cavity of the air inlet groove 3, and a moving rod 5 is slidably connected to the inner cavity of the fixing shell 4. With the cooperation of the fixed shell 4 and the moving rod 5, the volume of air inside the fixed shell 4 can be increased and the pressure can be decreased. At the same time, under the action of atmospheric pressure, the budget poster board can be fixed on the surface of the fixed plate 2, and the staff does not need to stick the budget poster board on the display board, which effectively prevents the stickiness of the glue from affecting the display board, thereby extending the service life of the display board. A rubber pad 6 is fixed at one end of the moving rod 5. The surface of the rubber pad 6 is slidably connected with the inner cavity of the fixed shell 4. The rubber pad 6 can increase the friction of the moving rod 5 when it is pulled out. The number of connecting rods 7 is several and they are symmetrically designed with respect to the central axis of the fixed plate 2. With the increase in the number, the connection between the moving rod 5 and the connecting rod 7 can be more uniform. A connecting block 8 is fixed on one side of the connecting rod 7. Under the action of the connecting block 8, multiple connecting rods 7 can be moved at the same time. A supporting block 9 is fixed on one side of the top of the base 1. A moving mechanism 10 is arranged above the supporting block 9. Under the action of the moving mechanism 10, the connecting block 8 can drive the moving rod 5 to move through the connecting rod 7, so that the air volume inside the fixed shell 4 increases and the pressure increases. The budget poster board is fixed on the surface of the fixed plate 2 under the action of atmospheric pressure, so that the staff does not need to stick the budget poster board on the surface of the fixed plate 2, which reduces the influence of glue residue on the display board and prolongs the service life of the display board. A fixed block 12 is fixed on one side of the support block 9, and a limiting mechanism 13 is provided in the inner cavity of the fixed block 12. Under the action of the limiting mechanism 13, the moving mechanism 10 can be more stable during operation, which prevents the connection block 8 from returning to its original position, thereby increasing the stability of the display board.

[0025] The moving mechanism 10 includes a gear bar 101, one side of the gear bar 101 is fixedly connected to one side of the connecting block 8, a first spur gear 102 is meshed at the top of the gear bar 101, a second spur gear 103 is meshed at the top of the first spur gear 102, a hand crank 104 is fixed to the inner cavity of the second spur gear 103, and with the cooperation of the hand crank 104 and the second spur gear 103, the first spur gear 102 can drive the connecting block 8 to move through the gear bar 101, and the connecting block 8 can drive multiple moving rods 5 to move simultaneously through the connecting rod 7, so that the air volume inside the fixed shell 4 becomes larger and the pressure becomes smaller. At the same time, under the action of atmospheric pressure, the budget poster board is fixed on the surface of the fixed plate 2, and there is no need for the staff to stick it with glue, which reduces the impact of the glue residue on the display board. The service life of the display board is increased. The volume of the first spur gear 102 is larger than that of the second spur gear 103 and they are used in conjunction with each other. Due to the size, the staff can save effort when turning the hand crank 104. The surface of the gear bar 101 is slidably connected to the inner cavity of the support block 9, which effectively prevents the gear bar 101 from shifting during operation, increases the stability of the mobile mechanism 10, and thus increases the stability of the display board. A bearing seat 11 is fixed to one side of the hand crank 104, and one side of the bearing seat 11 is fixedly connected to one side of the base 1. Under the action of the bearing seat 11, the hand crank 104 can be effectively prevented from shifting during operation, which increases the stability of the mobile mechanism 10, and thus increases the stability of the display board.

[0026] The limiting mechanism 13 includes a hand pull rod 131, the surface of the hand pull rod 131 is slidably connected to the inner cavity of the fixed block 12, a tension spring 132 is fixed to one side of the hand pull rod 131, one side of the tension spring 132 is fixedly connected to one side of the fixed block 12, a limiting groove 133 is provided on the surface of the gear bar 101, the inner cavity of the limiting groove 133 is slidably connected to the surface of the hand pull rod 131, under the action of the hand pull rod 131 and the tension spring 132, the hand pull rod 131 can be moved, so that the gear bar 101 can move to one side of the fixed block 12, and then under the action of the rebound of the tension spring 132, the hand pull rod 13 1 is moved to the inside of the limiting groove 133, so that the surface of the hand pull rod 131 is closely fitted with the inner cavity of the limiting groove 133, so as to limit the gear bar 101, effectively preventing the unstable situation of the moving mechanism 10 during operation, preventing the connection block 8 from moving back to the original position so that the budget poster board cannot be fixed on the surface of the fixed plate 2, increasing the stability of the moving mechanism 10, thereby increasing the stability of the display board, the hand pull rod 131 is located at the center of the tension spring 132, effectively preventing the tension spring 132 from shifting during operation, thereby increasing the stability of the limiting mechanism 13 during operation.

[0027] Working principle: When the staff needs to fix the budget poster board on the surface of the fixed plate 2, the staff uses the hand crank 104 to make the second spur gear 103 drive the first spur gear 102 to rotate, so that the first spur gear 102 drives the connecting block 8 to move through the gear bar 101, and at the same time, the connecting block 8 drives the moving rod 5 to move away from the fixed plate 2 through the connecting rod 7, so that the air volume inside the fixed shell 4 increases and the pressure decreases. At the same time, under the action of atmospheric pressure, the budget poster board can be squeezed, so that the budget poster board is fixed on the surface of the fixed plate 2. At the same time, the staff moves the hand rod 131 to the inside of the fixed block 12 through the cooperation of the hand rod 131 and the tension spring 132, so that the gear bar 101 moves to one side of the fixed block 12, and then under the action of the rebound of the tension spring 132, the hand rod 131 can be moved to the inside of the limiting groove 133, thereby preventing the gear bar 101 from moving. When the budget poster board needs to be removed, the hand rod 131 is pulled out of the limiting groove 133, and under the action of air pressure, the moving rod 5 returns to its original position, and then the staff can remove the budget poster board.
