Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the device comprises a screw rod 1, a coupler 2, a pressure arm 3, a driving threaded sleeve 4, a transmission sleeve 5 and an operating handle 6.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The embodiment is as follows: referring to fig. 1, a mechanical seal assembling tool for diving equipment comprises a screw rod 1, wherein one end of the screw rod 1 is detachably connected with a coupler 2 used for being connected with a shaft of the diving equipment; during specific implementation, shaft coupling 2 passes through the key with lead screw 1 and links to each other, like this, the dismantlement and the installation of the shaft coupling 2 of being convenient for to be convenient for have more different equipment axles, select different shaft couplings 2, improve the practicality of instrument.

The overhead cover of lead screw 1 is equipped with a pressure arm 3, one side that pressure arm 3 is close to shaft coupling 2 with can dismantle and be connected with a transmission sleeve 5, set up draw-in groove and fixture block respectively in sleeve and the adjacent one side of pressure arm 3 during the implementation to the mode that adopts the joint links to each other, and the assembly is simple, swift. The transmission sleeve 5 is sleeved on the screw rod 1, and gaps are formed between the transmission sleeve and the screw rod 1 as well as between the transmission sleeve and the coupler 2. Wherein, transmission sleeve 5 is the nylon material, can effectively avoid like this in the assembling process, and transmission sleeve 5 causes the damage to mechanical seal. Preferably, the pressure arm 3 is in a cross shape or an I shape, the middle part of the pressure arm is provided with a screw hole, and the pressure arm is connected with the screw rod in a threaded fit manner through the screw hole; in this way, the contact surface of the pressure arm 3 with the transmission sleeve 5 is larger, so that the force transmission stability is better.

When the device is specifically implemented, a limiting groove is formed in the screw rod along the length direction of the screw rod, a limiting block is arranged on the pressure arm 3 corresponding to the limiting groove, and the limiting block extends into the limiting groove and is connected with the limiting groove in a sliding fit manner; as optimization, two opposite sides of the screw rod 1 are provided with limiting grooves, and correspondingly, two opposite sides of the inner hole of the pressing arm 3 are provided with limiting blocks; therefore, the pressure arm 3 can be prevented from rotating in the moving process, and the mechanical seal damage caused by the rotation of the pressure arm 3 or the transmission sleeve 5 can be avoided.

And a driving threaded sleeve 4 is arranged on one side of the pressure arm 3, which deviates from the coupling 2, and the driving threaded sleeve 4 is in threaded fit connection with the screw rod 1. And an operating handle 6 is arranged on one side or two sides of the driving threaded sleeve 4, so that the operation and construction are more convenient. As optimization, the driving threaded sleeve 4 is a large and narrow cone, so that the contact area between the driving threaded sleeve 4 and the pressing arm 3 is larger, and the stability of force transmission can be effectively improved.

This scheme of adoption, the mechanical seal cover that will treat the installation now is epaxial at diving equipment during the use, then links to each other lead screw 1 and diving equipment's axle through shaft coupling 2, rotates drive thread bush 4 again, and drive thread bush 4 drives transmission sleeve 5 through pressure arm 3, promotes the mechanical seal through transmission sleeve 5 and removes until the mechanical seal installation is accomplished. Because the transmission sleeve 5 is in contact with the whole end face of the mechanical seal, the whole mechanical seal is accepted more evenly in the assembling process, and therefore damage to the mechanical seal, poor sealing effect and the like caused by unbalanced stress can be avoided. Moreover, by adopting the scheme, the construction precision can be greatly reduced, and the assembly efficiency is improved. Simultaneously, this scheme is through changing shaft coupling 2 and transmission sleeve 5, can adapt to different diving equipment and mechanical seal, and the adaptability is stronger.
