[0020] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use.

[0021] The sealing structure of the shell and the shell cover of the air-conditioning motor is achieved by the cooperation between the rubber pad, the T-shaped rubber block and the T-shaped groove. After the rubber pad is installed between the shell cover and the shell, the rubber pad needs to be oxidized from the outside, which increases the service life of the rubber pad and avoids the problem that although the existing air-conditioning motor sealing structure can achieve the sealing between the shell and the shell cover of the air-conditioning motor, the existing rubber ring is only installed between the shell and the shell cover of the air-conditioning motor.

The rubber pads are fixedly connected by bolts, and disassembly and replacement are time-consuming and laborious.

[0023] The sealing structure of the housing and the shell cover of the air-conditioning motor cooperates between the cross bar, the second clamping rod and the clamping block, so that after the second clamping rod clamps the clamping block, the cross bar contacts the second clamping rod to limit the second clamping rod, thereby enhancing the fixation of the second clamping rod to the clamping block.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-4 The present invention provides a technical solution: a sealing structure of a shell and a shell cover of an air-conditioning motor, comprising a shell cover 1, a shell 2 is provided at the bottom of the shell cover 1, a rubber pad 3 is fitted in the gap between the shell cover 1 and the shell 2, the inner walls of the rubber pad 3 are fitted with the outer walls of the shell cover 1 and the shell 2, and a limiting mechanism 4 is provided at the top and bottom of the rubber pad 3. The limiting mechanism 4 includes a T-shaped rubber block 401 and a T-shaped slot 402. A plurality of T-shaped rubber blocks 401 are processed in pairs at the top and bottom of the rubber pad 3. The number of the T-shaped rubber blocks 401 is four, and a plurality of T-shaped slots 402 are processed in pairs at the top of the shell 2 and the left and right sides of the bottom of the shell cover 1, respectively. The outer wall of the T-shaped rubber block 401 and the inner wall of the T-shaped slot 402 are interference fit, so that the T-shaped rubber block 401 fixes the rubber pad 3 at the gap between the shell cover 1 and the shell 2.

[0031] A connecting mechanism 5 is provided on the left and right sides of the rubber pad 3, and the connecting mechanism 5 includes a vertical block 501, an inner cavity 502 and a groove 503. The two vertical blocks 501 are respectively attached to the left and right sides of the rubber pad 3, the top and bottom of the two vertical blocks 501 are processed with the inner cavity 502, and the groove 503 is processed at the inner midpoint of the two vertical blocks 501.

[0032] A fixing mechanism 6 is provided inside the inner cavity 502, and the fixing mechanism 6 includes a slot block 601, a first clamping rod 602, a first pin shaft 603, a first spring 604, a screw rod 605 and a handle 606. The inner sides of the plurality of slot blocks 601 are fixedly connected to the left and right sides of the shell body 2 and the shell cover 1. There are four slot blocks 601. The outer wall of the slot block 601 passes through the inner side of the vertical block 501 and extends to the interior of the inner cavity 502, so that the slot block 601 can be inserted into the vertical block 501 and the interior of the inner cavity 502. The top and bottom of the slot block 601 are clamped with the first clamping rod 602, so that the shell body 2 and the shell cover 1 can be fixedly connected to the first clamping rod 602 through the slot block 601. The two first clamping rods 602 are rotatably connected to the rear end surface of the inner wall of the inner cavity 502 through the first pin shaft 603. A first spring 604 is clamped on the inner side of each first clamping rod 602, and the elastic coefficient of the first spring 604 is 5500-6000N\M. The first spring 604 gives a force to the two first clamping rods 602 to approach each other. The inner wall of the outer first clamping rod 602 is threadedly connected to a screw 605. The inner side of the screw 605 fits with the outer wall of the inner first clamping rod 602, so that the screw 605 drives the two first clamping rods 602 to rotate by rotating, and then the first clamping rod 602 clamps the slot block 601. The outer side of the screw 605 is threadedly connected to the outer side of the inner wall of the inner cavity 502, and a handle 606 is fixed to the outer side of the screw 605. The handle 606 is used to drive the screw 605 to rotate, and the surface of the handle 606 is processed with textures, and the textures are used to increase the friction between the handle and the hand.

[0033] A second fixing mechanism 7 is provided inside the groove 503, and the second fixing mechanism 7 includes a clamping block 701, a second clamping rod 702 and a second pin shaft 703. The two clamping blocks 701 are respectively fixed to the left and right sides of the rubber pad 3. The outer wall of the clamping block 701 is gap-matched with the inner wall of the groove 503, so that the clamping block 701 can be inserted into the inner wall of the groove 503. The top and bottom of the clamping block 701 are clamped with the second clamping rod 702, so that the rubber pad 3 can be fixed on the vertical block 501 through the clamping of the clamping block 701 and the second clamping rod 702. The two second clamping rods 702 are rotatably connected to the rear end surface of the inner wall of the groove 503 through the second pin shaft 703.

[0034] A locking mechanism 8 is provided on the outer side of the two vertical blocks 501, and the locking mechanism 8 includes a cross bar 801, a handle 802 and a second spring 803. The two cross bars 801 respectively penetrate the outer sides of the two vertical blocks 501 and extend to the inside of the groove 503. The outer wall of the cross bar 801 fits the inner side of the two second clamping rods 702, so that the cross bar 801 can limit the second clamping rod 702, so that the second clamping rod 702 fixes the clamping block 701, and the handle 802 is fixedly connected to the outer side of the cross bar 801, so that the handle 802 can drive the cross bar 801 to move left and right on the outer side of the vertical block 501. The outer wall gap of the cross bar 801 is matched with a second spring 803, and the elastic coefficient of the second spring 803 is 4500-5500N\M. The outer side of the second spring 803 is clamped on the inner side of the handle 802, and the inner side of the second spring 803 is clamped on the outer side of the vertical block 501. The second spring 803 gives the cross bar 801 an inward force.

[0035] When the sealing structure of the housing and the housing cover of the air-conditioning motor is used, when the rubber pad 3 is used for a long time and is seriously damaged by oxidation, the user turns the handle 606 to make the handle 606 drive the screw 605 to rotate. When the screw 605 rotates, it is no longer fitted with the outer wall of the inner first clamping rod 602. After the fitting is cancelled, the two first clamping rods 602 rotate through the elastic deformation of the first spring 604. During the rotation, the clamping and fixing with the clamping slot block 601 are cancelled. After the cancellation, the housing 2 and the housing cover 1 are cancelled. After the cancellation, the user pulls the housing cover 1 so that the T-shaped rubber Block 401 moves out of the T-slot 402. After cancellation, the user pulls the shell 2 to move the T-slot 401 out of the T-slot 402, thereby canceling the connection between the rubber pad 3, the shell 2 and the shell cover 1. After cancellation, the user pulls the handle 802, so that the handle 802 drives the cross bar 801 to cancel the fit with the two second clamping rods 702, thereby causing the cross bar 801 to cancel the limit on the second clamping rod 702. After cancellation of the limit, the user separates the two vertical blocks 501 from the rubber pad 3, so that the rubber pad 3 is disassembled, and then a new rubber pad 3 is replaced.
