[0002] With the rapid development of the construction industry, the mechanical and electrical systems of buildings are becoming increasingly complex, and the demand for equipment such as refrigeration units and air-conditioning water pumps is large. The vibration and noise generated by the operation of refrigeration units will have an adverse effect on the outside world. Therefore, central air-conditioning refrigeration units need to be equipped with spring shock absorbers. However, with the long-term operation of central air-conditioning refrigeration units, the spring shock absorbers will have a large offset, causing the central air-conditioning refrigeration units to deviate and become unstable, and the operation will be unstable, which will greatly reduce the operating efficiency of the refrigeration units, and even damage the equipment in serious cases.
[0003] At present, the conventional solution is to reinforce the central air conditioning refrigeration unit with wooden boards, but the strength of the wooden boards is low, and they are easily deformed and broken. In addition, the environment of the refrigeration room is humid, and the wooden boards are easy to rot, and the expected fixing effect cannot be achieved. Therefore, it is necessary to provide a limit device for the central air conditioning refrigeration unit, which can solve the problem in the prior art that the central air conditioning refrigeration unit is easy to become unstable after the spring shock absorber is offset.

[0007] An extension plate perpendicular to the plate surface of the limiting plate is formed on the other surface of the limiting plate, and the stiffening plate is fixedly connected to the limiting plate via the extension plate.

[0010] The limiting plate comprises a transverse plate and a longitudinal plate which are vertically connected. Both ends of the transverse plate and both ends of the longitudinal plate are formed with extension plates.

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Please see attached Figure 1 To Attachment Figure 4 A limiting device for a central air-conditioning refrigeration unit comprises a shock-absorbing rubber plate 1, a limiting plate 2, a stiffening plate 3 and a bottom plate 4; the bottom plate 4 is in an L-shaped corner structure, so that the bottom plate 4 can be matched and arranged on the outside of the corner of the central air-conditioning refrigeration unit, and is fixedly installed on the floor of the refrigeration room through a plurality of fixing parts 5; the limiting plate 2 is in an L-shaped corner structure and is vertically connected to the top edge of the bottom plate 4, and the limiting plate 2 is arranged along the outer wall at the corner of the central air-conditioning refrigeration unit; one surface of the shock-absorbing rubber plate 1 is fixedly attached to one surface of the limiting plate 2, and the other surface of the shock-absorbing rubber plate 1 is tightly attached to the outer wall at the corner of the central air-conditioning refrigeration unit; the stiffening plate 3 is vertically connected between the other surface of the limiting plate 2 and the bottom plate 4.
[0024] The bottom plate 4 can be made of thick steel plate, which is used to raise the limit plate 2, reduce the corrosion of the limit plate 2 in the humid environment of the refrigeration room, extend the service life, and improve the durability, so as to ensure the limit effect of the limit plate 2 on the central air-conditioning refrigeration unit. Usually, the central air-conditioning refrigeration unit is a rectangular structure, and the limit devices can be set at the four corners of the central air-conditioning refrigeration unit. The limit devices can also be customized according to the shape and size of the central air-conditioning refrigeration unit to limit the deviation of the central air-conditioning refrigeration unit from different directions to avoid the instability of the central air-conditioning refrigeration unit.
[0025] The limit plate 2 can be made of metal plates such as steel plates, and is used to form a surrounding reinforcement at the corners of the central air-conditioning refrigeration unit, which can effectively prevent the central air-conditioning refrigeration unit from becoming unstable when the spring shock absorber is offset. The corners of the central air-conditioning refrigeration unit transmit the vibration force to the L-shaped limit plate 2, and the stiffening plate 3 is installed in the force direction of the reinforcement plate 2 to transmit the force to the bottom plate 4 and the ground, thereby improving the bearing capacity of the limit plate 2, which is conducive to improving the operating stability of the central air-conditioning refrigeration unit.
[0026] The shock-absorbing rubber plate 1 is made of rubber material and has a good shock-absorbing effect. It is used to buffer the vibration of the central air-conditioning refrigeration unit and further improve the operating stability and reliability of the central air-conditioning refrigeration unit.
[0027] An extension plate 6 perpendicular to the plate surface of the limiting plate 2 is formed on the other surface of the limiting plate 2 , and the stiffening plate 3 is fixedly connected to the limiting plate 2 via the extension plate 6 .
[0028] The stiffening plates 3 and the extension plates 6 can be used to transfer the force of the limit plate 2 to improve the bearing capacity of the limit plate 2. The number of stiffening plates 3 and the extension plates 6 is the same, and the number of stiffening plates 3 and the extension plates 6 can be adaptively adjusted according to the actual limit reinforcement requirements.
[0029] The connected extension plate 6 and stiffening plate 3 are located in the same plane, thereby ensuring the force transmission effect.
[0030] The stiffening plate 3 is a right-angled triangle structure, and two right-angled sides of the right-angled triangle structure are respectively in contact with the extension plate 6 and the bottom plate 4 .
[0031] The triangular structure has high stability and can ensure the limiting effect of the limiting plate 2 on the central air conditioning refrigeration unit. The extension plate 6 and the bottom plate 4 are usually vertically connected, and the stiffening plate 3 can be set to a right-angled triangle structure to ensure that the connection between the stiffening plate 3, the extension plate 6 and the bottom plate 4 is tight and gap-free, thereby ensuring the limiting support and force transmission effect.
[0032] The limiting plate 2 comprises a transverse plate and a longitudinal plate connected vertically, and both ends of the transverse plate and the longitudinal plate are formed with extension plates 6 , and the four stiffening plates 3 are respectively connected between the four extension plates 6 and the bottom plate 4 .
[0033] The limit plate 2 provides limit reinforcement for the corners of the central air conditioning refrigeration unit in both the horizontal and vertical directions, which can effectively prevent the central air conditioning refrigeration unit from being displaced and unstable. The four extension plates 6 and the stiffening plate 3 divide the L-shaped bottom plate 4 into three areas, and at least one fixing member 5 can be set in each area to ensure the reliability of the connection between the bottom plate 4 and the ground of the refrigeration room. The fixing member 5 can preferably be a bolt.
[0034] The extension plate 6, the limiting plate 2, the stiffening plate 3 and the bottom plate 4 are connected into an integrated structure, which has high structural strength, long service life and good limiting effect.
[0035] The extension plate 6, the shock-absorbing rubber plate 1, the limit plate 2 and the stiffening plate 3 are of the same height, which can ensure that the vertical force of the entire limit device is uniform, and transmit the vertical force downward and outward to the bottom plate 4 and the ground through the stiffening plate 3.
[0036] Please see attached Figure 1 To Attachment Figure 4 , the manufacturing method of the utility model is:
[0037] According to the shape of the corners of the central air-conditioning refrigeration unit, a limit plate 2, a stiffening plate 3, a bottom plate 4 and an extension plate 6 are formed by cutting a steel plate with a thickness of 12 mm.
[0038] The bottom plate 4 is an L-shaped corner structure, which is used to surround the outside of the corner of the central air-conditioning refrigeration unit. The limit plate 2 is vertically set and welded along the inner edge of the bottom plate 4, so that one surface of the limit plate 2 can be set facing the corner of the central air-conditioning refrigeration unit. The shock-absorbing rubber plate 1 is bonded to one surface of the limit plate 2, and four extension plates 6 are vertically welded to the other surface of the limit plate 2, and are vertically distributed at both ends of the horizontal plate and the two ends of the longitudinal plate. The four stiffening plates 3 are respectively vertically welded and fixed between the four extension plates 6 and the bottom plate 4.
[0039] The bottom plate 4 is fixedly installed on the ground beside the corner of the central air-conditioning refrigeration unit through the fixing parts 5, so that the 10mm thick shock-absorbing rubber plate 1 is closely attached to the outer wall of the corner of the central air-conditioning refrigeration unit, which plays a shock-absorbing role and has the advantages of corrosion resistance, wear resistance, and impact resistance, and can effectively reduce the vibration and impact of the central air-conditioning refrigeration unit during operation.
[0040] Limiting devices are set at each corner of the central air-conditioning refrigeration unit. The installation method of each set of limiting devices is the same. Only the installation direction is different according to the setting direction of each corner of the central air-conditioning refrigeration unit, which will not be repeated here.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
