Description

Technical Field

[0001] The invention relates to the field of mechanical connection, in particular to an antifreeze keel aluminum plate device. Background Art

[0002] When the keel aluminum plate connection components in the equipment are used in the southern region, because the temperature difference between day and night is small, the keel material and the aluminum plate material are deformed slightly due to thermal expansion and contraction, and the requirements for the connection structure are loose. In the northern region, due to large temperature changes, the connection structures of different materials are deformed greatly due to thermal expansion and contraction, which will cause the connection to be stressed and cause the aluminum plate to be pulled and deformed, affecting the use of the product. Now a new keel aluminum plate connection structure is needed to overcome this problem and avoid damage to the equipment due to thermal deformation when used in the northern region. Summary of the invention

[0003] The object of the present invention is to provide an antifreeze keel aluminum plate device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an antifreeze keel aluminum plate device, comprising a T-shaped keel and an aluminum plate, a plurality of connecting plates being installed on the aluminum plate, a plurality of keel connecting rods being provided on the T-shaped keel, a plurality of aluminum plate connecting rods being provided on the connecting plate, an annular step being provided at the middle position of the keel connecting rod and the aluminum plate connecting rod, threads being processed on the upper parts of the keel connecting rod and the aluminum plate connecting rod, nuts being screwed on the upper parts of the keel connecting rod and the aluminum plate connecting rod, the keel connecting rod and the aluminum plate connecting rod being matched with the rings at both ends of the tension spring, and the T-shaped keel being connected to the aluminum plate through the tension spring.

[0005] Preferably, the connecting plate is detachably connected to the aluminum plate by screws or is directly bonded to the aluminum plate by an adhesive.

[0006] Preferably, the keel connecting rods are arranged at three ends of the T-shaped keel, and the number of the keel connecting rods is three.

[0007] Preferably, the collar is clamped by the annular step and the nut.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: when the antifreeze keel aluminum plate device is used, the nut is unscrewed, and then the collar at one end of the tension spring is first sleeved on the keel connecting rod, and then the nut is screwed in, so that the collar at one end of the tension spring will be squeezed by the nut and the annular step, so that the fixation of one end of the tension spring is achieved, and then the aluminum plate with the fixed connecting plate is buckled on the T-shaped keel, each connecting plate corresponds to one end of the T-shaped keel, and each keel connecting rod corresponds to three aluminum plate connecting rods. After the aluminum plate is buckled, the movable end of the tension spring with one end fixed on the keel connecting rod is matched with the aluminum plate connecting rod, and after the collar is sleeved on the aluminum plate connecting rod, the nut is screwed into the aluminum plate connecting rod. Rod, the rings at both ends of the tension spring are fixed at this time, thus completing the connection between the aluminum plate and the T-shaped keel. When the temperature difference changes greatly, due to the different materials used, the aluminum plate and the T-shaped keel have different thermal expansion and contraction coefficients and different deformation amounts. Therefore, when the two are relatively displaced, the tension spring will be compressed or stretched, playing the role of elastic connection, avoiding the problem of the aluminum plate being pulled and deformed by the keel, protecting the shape of the aluminum plate, and ensuring the stability of the working state. The device has a simple structure, is easy to install, has a detachable connection, and is easy to replace. It can overcome the problem of structural damage caused by deformation of the keel and aluminum plate caused by temperature changes, and extend the service life of the device.
