The mounting ring 140 is inserted into the mounting hole 110. The reinforcing ring 130 includes an upper ring 131 and a lower ring 132. The upper ring 131 is arranged on the lower ring 132. Embodiment 1, this embodiment is intended to promote the solution to the problem that the existing gear pump 300 for machine tools is not firm enough at the connection, and the weak connection may cause liquid leakage at the connection between the pump and the pipeline. On this upper side, an adjustment component 400 is arranged between the upper ring 131 and the lower ring 132 for adjustment.

[0025] The gear pump 300 is a commonly used hydraulic transmission device that sucks in liquid by rotating gears and delivers it out by pressure. The gear pump 300 set in the box 100 will rotate the gears during operation, suck in lubricating oil and compress it to deliver it to the required parts to achieve the functions of lubrication and transmission. The connecting pipe 120 plays the role of a bridge between the lubrication system in the box 100 and the gear pump 300. The two ends of the connecting pipe 120 are respectively plugged into the suction port and outlet of the gear pump 300, and the lubricating oil provided in the box 100 is delivered from the box 100 to the gear pump 300, thereby ensuring the lubricating oil required for the normal operation of the gear pump 300. The lubricating oil enters the connecting pipe 120 through the mounting hole 110 in the box 100, and after being delivered by the connecting pipe 120, one end is plugged into the suction port of the gear pump 300 through the connecting pipe 120, so as to supply the gear pump 300 for suction, and the other end is connected to the outlet of the gear pump 300, and the compressed lubricating oil is delivered to the required parts for lubrication.

[0026] The adjustment assembly 400 includes a slot 410 provided in the lower ring 132, a strip 420 corresponding to the slot 410 is installed at the bottom of the upper ring 131, the strip 420 is movably engaged with the slot 410, a first engaging rack 411 is installed in the slot 410, a second engaging rack 421 corresponding to the first engaging rack 411 is installed in the upper ring 131, and the first engaging rack 411 is meshed with the second engaging rack 421. A limiting slot 430 is provided outside the reinforcement ring 130, a tightening rope 431 is arranged in the limiting slot 430, a guide ring 440 is installed at the end of the reinforcement ring 130 near the limiting slot 430, a tightening ring 450 is installed at the guide ring 440 reinforcement ring 130 near the connection between the upper ring 131 and the lower ring 132, and the tightening rope 431 is wound around the tightening ring 450 through the guide ring 440.

[0027] The guide ring 440 and the tightening ring 450 are both provided in two groups, one group of the guide ring 440 and the tightening ring 450 is provided outside the upper ring 131, and the other group of the guide ring 440 and the tightening ring 450 is symmetrically provided outside the lower ring 132. A limit ring 460 is fixedly installed on the box body 100, the limit ring 460 is located at the side of the tightening ring 450, a driving screw 470 is inserted in the limit ring 460, and the driving screw 470 is provided as a bidirectional screw, and a driving gear 451 corresponding to the driving screw 470 is fixedly installed outside the tightening ring 450, the driving gear 451 is located at the rear side of the tightening rope 431, and the driving gear 451 is meshed with the driving screw 470. Limit plates 471 are installed at both ends of the limit ring 460, the diameter of the limit plate 471 is larger than the diameter of the driving screw 470, and a driving button 472 for controlling the driving screw 470 is fixedly installed on the limit plate 471.

[0028] When installing, first turn the control button clockwise to control the drive screw 470 to rotate, thereby engaging with the drive gear 451. As the drive gear 451 rotates, the tightening rope 431 originally wrapped around the tightening ring 450 is released, and then the upper ring 131 and the lower ring 132 are bent to make the second engaging rack 421 engage with the first engaging rack 411, so that the locking bar 420 is withdrawn from the locking groove 410. At this time, the connecting pipe 120 is passed through the upper ring 131 and the lower ring 132 and installed with the gear pump 300.

[0029] When it is confirmed that the installation of the connecting tube 120 and the gear pump 300 is complete, the driving button 472 is rotated in the opposite direction again, so that the driving screw 470 controls the driving gear 451 to rotate in the opposite direction, so that the tightening rope 431 is reeled in. As the tightening rope 431 is reeled in, the upper ring 131 and the lower ring 132 are driven to approach each other. At this time, the first engaging rack 411 and the second engaging rack 421 are meshed in opposite directions, so that the engaging strip 420 is engaged with the engaging groove 410. At this time, the upper ring 131 and the lower ring 132 are closed, thereby achieving the clamping and fixation of the connecting tube 120.

Through the rotation of the control button, the tightening rope 431 is retracted and released, thereby controlling the clamping and fixing of the connection, which is convenient for installing and fixing the connecting tube 120. At the same time, the tightening rope 431 is released by rotating the control button clockwise, the connecting tube 120 and the gear pump 300 are installed, and then the control button is rotated counterclockwise to tighten the connecting tube 120 to achieve the purpose of clamping and fixing.

[0031] Embodiment 2: This embodiment is intended to promote the solution of the support force problem at the connection. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Figure 4 .
