Description

Technical Field

[0001] The utility model relates to the technical field of tension sensors, and more specifically, to an S-shaped tension sensor. Background Art

[0002] An S-type tension sensor is used to display the value of tension. Generally, the tension is transmitted by pulling the pull rings at both ends of the S-type tension sensor. The pull rings are screwed into both ends of the S-type tension sensor to connect the pull rings with the S-type tension sensor, thereby enabling tension sensing. However, when pulling, the pull ring is subjected to a large tension, which may cause the S-type tension sensor to separate from the pull ring, thereby causing the pull ring to fall off. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an S-shaped tension sensor, which has the advantage of improved stability.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an S-shaped tension sensor, comprising a tension sensor, wherein the upper and lower ends of the tension sensor are threadedly connected to a threaded rod, the side of the threaded rod away from the tension sensor is fixedly connected to a clamping plate, the side of the clamping plate away from the threaded rod is fixedly connected to a pull ring, a clamping groove is provided on the side of the clamping plate, the upper and lower ends of the tension sensor are fixedly connected to a clamping bin, the inner cavity of the clamping bin is fixedly connected to a clamping spring, the middle part of the clamping bin is movably sleeved with a pull rod, and the side of the pull rod close to the clamping plate is fixedly connected to a clamping block.

[0005] As an optimal technical solution of the present invention, the right side of the tension sensor is threadedly connected to a mounting bolt, the inner cavity of the mounting bolt is movably sleeved with a mounting plate, the right side of the mounting plate is fixedly connected to a fixing ring, the side of the fixing ring close to the center of the tension sensor is fixedly connected to a contact sleeve, the right side of the tension sensor is fixedly connected to a connector, and the right side of the connector is fixedly connected to a power cord.

[0006] As a preferred technical solution of the present invention, a resistance strain gauge is provided on the front side of the tension sensor, threaded holes are provided on the upper and lower sides of the tension sensor, and the threaded rod is threadedly connected in the threaded holes.

[0007] As a preferred technical solution of the present invention, the pull rod is located at the center of the inner cavity of the clamping spring, and the clamping chamber is a rectangular cavity.

[0008] As a preferred technical solution of the present invention, the pull rod is composed of a round rod and a circular ring, the round rod is fixedly connected to the clamping block, and the circular ring is located outside the clamping bin.

[0009] As a preferred technical solution of the present invention, the fixing ring is semicircular, and the contact sleeve contacts the surface of the power line.

[0010] As a preferred technical solution of the present invention, the power line is electrically connected to the tension sensor, and the mounting plate is L-shaped.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model drives the clamping block away from the clamping plate by pulling the pull rod. Then, after the threaded rod is threadedly connected to the inner cavity of the tension sensor, the pull rod is released, and the tension of the clamping spring drives the clamping block to be inserted into the inner cavity of the clamping groove, thereby clamping the clamping plate. Then, the user pulls the pull ring to perform tension sensing, thereby improving the connection strength between the threaded rod and the tension sensor, greatly improving the stability of the connection between the threaded rod and the tension sensor, and thus improving the stability when using the tension sensor and the pull ring for tension sensing.

[0013] 2. The utility model uses mounting bolts to threadably connect the mounting plate, thereby fixing the fixing ring through the mounting plate, and then contacts the power cord through the contact sleeve to support and fix the power cord. In this way, when the user uses the tension sensor to drive the tension sensor to move, the power cord and the connector are bent and twisted, resulting in a break between the power cord and the connector, which greatly improves the stability during use.

[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the utility model provides an S-shaped tension sensor, including a tension sensor 1, wherein the upper and lower ends of the tension sensor 1 are both threadedly connected to a threaded rod 2, a side of the threaded rod 2 away from the tension sensor 1 is fixedly connected to a clamping plate 3, a side of the clamping plate 3 away from the threaded rod 2 is fixedly connected to a pull ring 4, a side of the clamping plate 3 is provided with a clamping groove 5, the upper and lower ends of the tension sensor 1 are fixedly connected to a clamping bin 6, an inner cavity of the clamping bin 6 is fixedly connected to a clamping spring 7, a middle part of the clamping bin 6 is movably sleeved with a pull rod 8, and a side of the pull rod 8 close to the clamping plate 3 is fixedly connected to a clamping block 9;

[0022] By pulling the pull rod 8, the clamping block 9 is driven away from the clamping plate 3. Then, after the threaded rod 2 is threadedly connected to the inner cavity of the tension sensor 1, the pull rod 8 is released, and the tension of the clamping spring 7 drives the clamping block 9 to be inserted into the inner cavity of the clamping groove 5, thereby clamping the clamping plate 3. Then the user pulls the pull ring 4 for tension sensing, thereby improving the connection strength between the threaded rod 2 and the tension sensor 1, greatly increasing the stability of the connection between the threaded rod 2 and the tension sensor 1, thereby improving the stability when using the tension sensor 1 and the pull ring 4 for tension sensing.

[0023] The right side of the tension sensor 1 is threadedly connected to a mounting bolt 11, the inner cavity of the mounting bolt 11 is movably connected to a mounting plate 12, the right side of the mounting plate 12 is fixedly connected to a fixing ring 13, and the side of the fixing ring 13 near the center of the tension sensor 1 is fixedly connected to a contact sleeve 14. The right side of the tension sensor 1 is fixedly connected to a connector 15, and the right side of the connector 15 is fixedly connected to a power cord 16;

[0024] By using the mounting bolt 11 to threadably connect the mounting plate 12, the fixing ring 13 is fixed by the mounting plate 12, and then the contact sleeve 14 contacts the power cord 16, thereby supporting and fixing the power cord 16. In this way, when the user uses the tension sensor 1 to drive the tension sensor 1 to move, the power cord 16 and the connector 15 are bent and twisted, resulting in a break between the power cord 16 and the connector 15, thereby greatly improving the stability during use.

[0025] The front side of the tension sensor 1 is provided with a resistance strain gauge 10, and the upper and lower sides of the tension sensor 1 are provided with threaded holes, and the threaded rod 2 is threadedly connected in the threaded holes;

[0026] Through the resistance strain gauge 10 on the front side of the tension sensor 1, the tension sensor 1 can be used in combination with the resistance strain gauge 10, and then through the threaded holes on the upper and lower sides of the tension sensor 1, the threaded rod 2 can be threadedly connected in the threaded holes, so that the user can use the pull ring 4 for tension sensing.

[0027] The pull rod 8 is located at the center of the inner cavity of the clamping spring 7, and the clamping chamber 6 is a rectangular cavity;

[0028] Because the pull rod 8 is located at the center of the inner cavity of the clamping spring 7, the pull rod 8 can evenly pull the clamping block 9 in the direction of the clamping spring 7, and can also evenly transfer force to the clamping block 9 through the clamping spring 7, so that the clamping block 9 can be stably inserted into the inner cavity of the clamping groove 5.

[0029] The pull rod 8 is composed of a round rod and a circular ring. The round rod is fixedly connected to the clamping block 9, and the circular ring is located outside the clamping bin 6.

[0030] By setting the circular ring, the user can pull the circular ring to move the circular rod, and then drive the clamping block 9 to move through the circular rod, so that the clamping block 9 can be moved away from the clamping groove 5, so that the threaded rod 2 can be screwed into the inner cavity of the tension sensor 1 without obstruction.

[0031] The fixing ring 13 is semicircular, and the contact sleeve 14 contacts the surface of the power line 16;

[0032] Since the fixing ring 13 is semicircular, the fixing ring 13 can drive the contact sleeve 14 to contact the surface of the power line 16, and the fixing ring 13 can support and fix the power line 16 to prevent it from twisting and breaking.

[0033] Among them, the power line 16 is electrically connected to the tension sensor 1, and the mounting plate 12 is L-shaped;

[0034] The power cord 16 is electrically connected to the tension sensor 1, so that the power cord 16 can transmit the signal sensed by the tension sensor 1 to the external display device. The mounting plate 12 is L-shaped, so that the mounting plate 12 can be fixed by the mounting bolts 11. Different lengths of the mounting plate 12 can be selected according to actual needs, making it suitable for narrower environments.

[0035] The working principle and usage process of the present invention are as follows: the mounting plate 12 is threadedly connected to the tension sensor 1 through the mounting bolts 11, thereby fixing the mounting plate 12, and then the power cord 16 is wrapped around the fixing ring 13 near the center of the tension sensor 1, thereby fixing the power cord 16, thereby preventing the power cord 16 from being broken due to bending between the power cord 16 and the connector 15;

[0036] Then, pull the pull rod 8 to drive the clamping block 9 to move, and then thread the threaded rod 2 to the upper and lower ends of the tension sensor 1. At this time, the clamping groove 5 is aligned with the clamping block 9. Then, release the pull rod 8. The tension of the clamping spring 7 drives the clamping block 9 to clamp into the inner cavity of the clamping groove 5, thereby clamping and limiting the clamping plate 3, thereby improving the stability of the connection between the threaded rod 2 and the tension sensor 1.

[0037] Then, the tension value is displayed by pulling the two pull rings 4.
