[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element for pressure measuring instruments to convert pressure into displacement or force. Wires refer to conductors that transmit electrical energy. They are divided into bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires and various profiles. It is mainly used for outdoor overhead and indoor busbars and switch boxes. The surface of outdoor wires is generally protected by corrugated tubes. However, the protective structure of corrugated tubes currently used outdoors is generally poor. For example, when installed outdoors, they are generally in direct contact with the ground. The bottom is easily corroded and oxidized by water and other chemicals on the ground, which causes the bellows to age easily and reduce its service life. In addition, the current bellows connection method is relatively cumbersome, affecting the installation efficiency. Utility Model Content

[0034] Example 2

[0035] Reference Figure 3 , Figure 5 and Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the bellows assembly 100 further includes a connecting plate 105 and a tooth plate 106 . The connecting plate 105 is fixed to the front and rear sides of the first clamping ring 103 , and the tooth plate 106 is fixed to one side of the connecting plate 105 .

[0037] The tooth plate 106 is conveniently fixed to the first clamping ring 103 through the connecting plate 105 , and the mounting member 202 is conveniently clamped through the tooth plate 106 .

[0038] Specifically, the bellows assembly 100 also includes a reinforcement plate 107 and a first spring group 108. The reinforcement plate 107 is fixed to one side of the connecting plate 105 and the other side is fixedly connected to the first retaining ring 103. The first spring group 108 is fixed to the surface of the bellows body 102 and the side away from the bellows body 102 is fixedly connected to the support ring 101.

[0039] The fixed connection between the reinforcing plate 107 and the first clamping ring 103 can strengthen the connection strength between the connecting plate 105 and the first clamping ring 103. The two ends of the first spring group 108 are respectively connected to the bellows body 102 and the support ring 101, so as to provide a protective and anti-buffering effect for the bellows body 102.

[0040] Specifically, the bellows assembly 100 further includes a sealing groove 109 and a sealing ring 110 . The sealing groove 109 is opened on one side of the second clamping ring 104 . The sealing ring 110 is fixed on one side of the first clamping ring 103 , and its surface contacts the inside of the sealing groove 109 .

[0041] Through the movable contact between the sealing groove 109 and the sealing ring 110, the sealing effect when the second clamping ring 104 and the first clamping ring 103 are spliced ​​can be improved to prevent leakage in rainy days.

[0042] Specifically, the mounting member 202 includes a partition 202a, a second spring group 202b, a clamping plate 202c and a pressing rod 202d, the partition 202a is fixed to the inner wall of the positioning shell 201, the second spring group 202b is fixed to the top and bottom of the partition 202a, the clamping plate 202c is fixed to the side away from the second spring group 202b, the pressing rod 202d is fixed to the side of the clamping plate 202c away from the second spring group 202b, and passes through to the outside of the positioning shell 201.

[0043] When the user needs to disassemble the corrugated tube body 102 for maintenance of the wires, the user presses down the pressing rod 202d to make the clamping plate 202c squeeze the second spring group 202b. At this time, the second clamping plate 202c is separated from the surface of the tooth plate 106, and the first clamping ring 103 can be removed.

[0044] Specifically, the mounting member 202 further includes a slide groove 202e and a slider 202f. The slide groove 202e is provided on both sides of the positioning shell 201. The slider 202f is fixed to the front and rear sides of the clamping plate 202c, and the surface is slidably connected with the inside of the slide groove 202e.

[0045] The sliding connection between the slider 202f and the slide groove 202e plays a role in assisting the movement of the clamping plate 202c.

[0046] Specifically, the mounting member 202 further includes a protective shell 202g, which is fixed to the top and bottom of the positioning shell 201, and the inner cavity of the protective shell 202g is in active contact with the pressing rod 202d.

[0047] The fixed connection between the protective shell 202g and the positioning shell 201 plays the role of protecting the pressing rod 202d.

[0048] Example 3

[0049] Reference Figure 4, which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the adjusting member 203 includes a connecting ring 203a, a connecting block 203b and a nut 203c. The connecting ring 203a is sleeved on the surface of the supporting ring 101, the connecting block 203b is fixed to the front and rear sides of the bottom of the connecting ring 203a, and the nut 203c is arranged at the bottom of the connecting block 203b.

[0051] The connecting ring 203a is made of elastic material and the connecting parts are connected by bolts, so that it is convenient to put it on the surface of the supporting ring 101 for assembly, and the supporting height is conveniently adjusted by the connecting block 203b and the nut 203c.

[0052] Specifically, the adjusting member 203 further includes a screw 203d and a base 203e. The screw 203d is disposed in the inner cavity of the nut 203c, and the surface is threadedly connected to the inner cavity of the connecting block 203b. The base 203e is fixed to the bottom of the screw 203d.

[0053] When the user needs to adjust the height, the user twists the nut 203 c to move the screw rod 203 d to drive the base 203 e to descend, thereby supporting the support ring 101 .

[0054] Specifically, the adjusting member 203 further includes an anti-skid pad 203f, which is fixed to the bottom of the base 203e, and the material of the anti-skid pad 203f is rubber.

[0055] Since the anti-skid pad 203f is made of rubber, the friction between the base 203e and the ground can be increased to prevent sliding.

[0056] When in use, the first snap ring 103 can first drive the connecting plate 105 and the tooth plate 106 to be inserted into the inner cavity of the positioning shell 201. At this time, the second spring group 202b is forced to drive the clamping plate 202c to retract. Until the tooth plate 106 is fully inserted into the positioning shell 201, the second spring group 202b is reset to drive the inclined surface of the clamping plate 202c to engage with the tooth plate 106 for installation. At this time, the first snap ring 103 drives the sealing ring 110 to be inserted into the sealing groove 109 of the second snap ring 104, thereby improving the sealing performance. Through the connection between the two ends of the first spring group 108 and the bellows body 102 and the support ring 101 respectively, the bellows body 102 can be protected and buffered. When the user needs to adjust the distance between the support ring 101 and the ground, the nut 203c is twisted to make the screw 203d rotate in the inner cavity of the connecting block 203b, and the contact distance between the base 203e and the ground is adjusted, thereby adjusting the support height.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
