Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic mopping belts, and in particular relates to a tightening structure for an electrostatic mopping belt of an oil tanker. Background Art

[0002] When the tanker is driving, the oil transported in the vehicle shakes back and forth, causing friction with the metal inner wall of the tank, thus generating static electricity. When the static electricity reaches a certain level, sparks will be generated, causing the tank to explode. Therefore, the tail of the tanker is connected to an static drag belt (not an iron chain). The static drag belt is a rubber flat belt with two sets of thick copper wires connected to the tank body. When the tanker is moving, the static electricity generated by the friction between the body and the oil in the tank will be introduced into the ground through the thick copper wire, discharging the static electricity in the tank and preventing the oil from burning due to sparks generated by static electricity discharge, thereby ensuring the safety of the tanker and avoiding accidents.

[0003] The electrostatic mop belt is usually a long static-conducting rubber belt, one end of which is connected to the vehicle and the other end is in frictional contact with the ground. As the friction continues, the bottom end of the electrostatic mop belt will become shorter due to friction loss, resulting in failure to ground. Therefore, a tightening structure is provided in the middle of the electrostatic mop belt to fold and tighten the belt body, so as to adjust and release the length of the electrostatic mop belt, so that the bottom end of the electrostatic mop belt always keeps in contact and friction with the ground. However, the existing tightening structure generally realizes the tightening function directly through bolts and clamps. In the process of adjustment and release, tools such as screwdrivers are inevitably required, which makes adjustment more troublesome. The tightening function will also fail and get stuck due to rust and aging of the bolts, reducing the tightening and release efficiency and service life of the electrostatic mop belt.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0022] Example:

[0023] like Figure 1-4 As shown, this embodiment provides a tightening structure of an electrostatic drag belt for a tank truck, including a belt body 1, a fixing member 2 is fixedly installed on the top of the belt body 1 and is threadedly connected to the bottom of the tank truck through the fixing member 2, the bottom end of the belt body 1 is suspended on the ground, a tightening member 3 is clamped in the middle of the belt body 1 and is folded and tightened through the tightening member 3, the tightening member 3 has a first clamping plate 4 and a second clamping plate 5 arranged in parallel, both ends of the first clamping plate 4 and the second clamping plate 5 are penetrated with openings and provided with plug holes 6, a tightening rod 8 is slidably connected in the plug hole 6, an annular rotating plate is embedded in the outer surface of the first clamping plate 4 and a spring 10 is fixedly installed through the annular rotating plate;

[0024] The second clamping plate 5 is fixedly mounted with an elastic member 7 on one side away from the first clamping plate 4. The elastic member 7 has two elastic plates 15 arranged opposite to each other.

[0025] A connecting plate 9 and a contact end 12 are respectively formed integrally at both ends of the tightening rod 8 , and a clamping groove 11 is formed at one end of the tightening rod 8 close to the contact end 12 .

[0026] In a specific application scenario, by rotating, pulling and sliding the tightening rod 8 as a whole, the tightening member 3 and the first clamping plate 4 are gradually separated and the distance between them is increased, so that the belt body 1 clamped and gathered between the tightening member 3 and the first clamping plate 4 can be pulled longitudinally, so that the bottom end of the belt body 1 is stretched, and then the height of contact and friction with the ground is restored, so as to maintain the static electricity conductive function of the belt body 1; and after the force driving the handle 13 is released, the spring 10 will be elastically reset to pull the tightening rod 8 to reset as a whole, and then the user rotates the tightening rod 8 to reset the slot 11 and continue to engage with the two elastic plates 15, so that the tightening member 3 and the first clamping plate 4 resume continuous clamping of the belt body 1, and maintain the folded and gathered state of the belt body 1. The following is a further description of the practical tank truck static drag zone tightening structure in combination with this application scenario.

[0027] Further, refer to Figure 1-4 There are two tightening rods 8 and they are arranged in parallel on both sides of the belt body 1. The tightening rods 8 penetrate and are inserted into the same end insertion holes 6 of the first clamping plate 4 and the second clamping plate 5.

[0028] In this embodiment, the tightening rod 8 is inserted through the same end socket 6 of the first clamping plate 4 and the second clamping plate 5, so that the first clamping plate 4 and the second clamping plate 5 are kept connected, and the belt body 1 can be clamped between the first clamping plate 4 and the second clamping plate 5. At the same time, by arranging the tightening rod 8 in parallel on both sides of the belt body 1, the tightening member 3 and the first clamping plate 4 can be used to clamp the two sides of the belt body 1 synchronously, so as to keep the force balance on both sides of the belt body 1, and thus maintain the stable clamping of the belt body 1.

[0029] For more details, see Figure 1-4 The two elastic plates 15 are tilted and set to make the bottom ends contact each other through elastic setting, and the contact end 12 is set in a hemispherical shape.

[0030] In this embodiment, due to the elastic properties of the elastic plates 15, the contacting parts will be elastically clamped after the mutual abutment, so that the tightening rod 8 can be clamped and fixed. Moreover, since the two elastic plates 15 actually form a blockage for the end of the tightening rod 8 after the mutual abutment, in order to prevent the end of the tightening rod 8 from being stuck by the two elastic plates 15, the abutting end 12 is set to be hemispherical, so that when the tightening rod 8 is blocked by the two elastic plates 15, the two elastic plates 15 can be squeezed apart, thereby facilitating the pulling and sliding of the tightening rod 8.

[0031] More preferably, referring to Figure 1-4 There are two card slots 11 symmetrically distributed on the outer circumferential wall of the tightening rod 8 , and the bottom end of the elastic plate 15 also protrudes outward to fit with the card slots 11 for engagement.

[0032] In this embodiment, since the tanker truck is inevitably bumpy during its travel, the belt body 1 as a whole also swings accordingly. The end of the tightening rod 8 is limited by the engagement of the elastic plate 15 and the slot 11, which not only prevents the tightening rod 8 from being pulled out but also prevents the tightening rod 8 from rotating, so that the end of the tightening rod 8 is stably clamped by the two elastic plates 15, thereby maintaining the stable clamping of the belt body 1 by the first clamping plate 4 and the second clamping plate 5.

[0033] More preferably, referring to Figure 1-4 The spring 10 is arranged around the insertion hole 6 and one end away from the first clamping plate 4 is fixedly connected to the connecting plate 9.

[0034] In this embodiment, during the process of rotation, pulling and sliding of the tightening rod 8, since the outer surface of the first clamping plate 4 is embedded with an annular rotating plate and is fixedly connected to the spring 10 through the annular rotating plate, the tightening rod 8 and the connecting plate 9 will drive the annular rotating plate to rotate during rotation without affecting the elastic connection between the first clamping plate 4 and the connecting plate 9. Therefore, after the user releases the force driving, the spring 10 will elastically reset and pull the tightening rod 8 to reset as a whole. Then the user rotates the tightening rod 8 to reset the slot 11 and continue to engage with the two elastic plates 15, so that the tightening member 3 and the first clamping plate 4 resume continuous clamping of the belt body 1, thereby maintaining the folded and contracted state of the belt body 1.

[0035] Furthermore, refer to Figure 1-4 A handle 13 is mounted on the outer surface of the connection plate 9 , and a rubber cushion 14 is disposed around the insertion hole 6 on one side of the first clamping plate 4 facing the second clamping plate 5 .

[0036] In the present embodiment, during the process of adjusting and releasing the belt body 1, in order to facilitate the user to hold and apply force to drive, a handle 13 is provided to facilitate the user to hold; and due to the elastic characteristics of the spring 10, it will continuously apply elastic pressure to clamp the first clamping plate 4 and the second clamping plate 5 towards each other. In order to avoid direct collision between the first clamping plate 4 and the second clamping plate 5 driven by elastic force during installation and disassembly and cause damage, a rubber buffer pad 14 is provided on the first clamping plate 4 for buffering.

[0037] Working principle:

[0038] The utility model discloses a tightening structure for the electrostatic mopping belt of a tank truck. When the bottom end of the belt body 1 suspended on the ground is shortened due to friction loss with the ground, the length of the belt body 1 needs to be adjusted and released so that the bottom end of the electrostatic mopping belt always keeps in contact and friction with the ground.

[0039] At this time, first, the handle 13 is held to drive the tightening rod 8 to rotate as a whole. Due to the setting of the clamping groove 11 at the end of the tightening rod 8, the tightening rod 8 will push the two elastic plates 15 of the elastic member 7 during the rotation, so that the two elastic plates 15 that are in elastic resistance with the clamping groove 11 are stretched under force, and as the tightening rod 8 rotates, the elastic plates 15 are separated from the clamping groove 11 and are in resistance with other outer circumferential wall parts of the tightening rod 8, thereby releasing the engagement between the clamping groove 11 and the elastic plates 15, and then the tightening rod 8 can be pulled and slid as a whole, so that the tightening member 3 and the first clamping plate 4 are gradually separated and the distance between the two is increased, so that the belt body 1 clamped and gathered between the tightening member 3 and the first clamping plate 4 can be pulled longitudinally, so that the bottom end of the belt body 1 is stretched, and then the height of contact and friction with the ground is restored, thereby maintaining the static electricity conductive function of the belt body 1;

[0040] Due to the setting of the spring 10, an elastic connection is formed between the first clamping plate 4 and the connecting plate 9. The outer surface of the first clamping plate 4 is embedded with an annular rotating plate and is fixedly connected to the spring 10 through the annular rotating plate. Therefore, the tightening rod 8 and the connecting plate 9 will drive the annular rotating plate to rotate during rotation without affecting the elastic connection between the first clamping plate 4 and the connecting plate 9.

[0041] Therefore, when the user pulls the tightening rod 8 out of the insertion hole 6 and slides it through the handle 13, the spring 10 will be driven to stretch elastically and store force synchronously. After the user completes the adjustment and release of the length of the belt body 1 and releases the force driving on the handle 13, the spring 10 will elastically reset and pull the tightening rod 8 to reset as a whole. Then the user rotates the tightening rod 8 to reset the slot 11 and continue to engage with the two elastic plates 15, so that the tightening member 3 and the first clamping plate 4 resume continuous clamping of the belt body 1, maintaining the folded and contracted state of the belt body 1.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
