Description

Technical Field

[0001] This utility model relates to the field of torque wrenches, specifically a portable steel space frame torque detection device. Background Technology

[0002] With the development of industrial buildings, large-span factory roofs generally adopt spatial grid structures. Their installation and maintenance are highly dependent on the connection quality of high-strength bolts. Using a torque wrench can improve the connection quality of high-strength bolts.

[0003] Traditional torque wrenches are not portable enough for high-altitude operations. When constructing roof steel space frame structures, workers need to climb to the space frame at a height of tens of meters, making it difficult to carry the wrench, increasing labor intensity and safety risks. Therefore, this utility model provides a portable steel space frame torque detection device. Utility Model Content

[0004] To address the lack of portability in existing torque wrenches, this invention provides a portable steel grid frame torque detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable steel space frame torque detection device, comprising:

[0007] Control components;

[0008] A ratchet wrench head mounted on one end of the control mechanism;

[0009] The control component is divided into a main body section and a torque adjustment section along the reminder section of the control component, and the outer shell of the main body section and the outer shell of the torque adjustment section are hinged by a folding connector;

[0010] The hinge axis of the folding connector is parallel to the working surface of the ratchet wrench head;

[0011] The lower part of the driving rod inside the main body section is equipped with a reminder, and the upper part of the spring seat rod inside the torque adjustment section is equipped with a reminder.

[0012] The lower and upper parts of the reminder component are wedge-shaped, and the wedge-shaped mating surface is perpendicular to the working surface of the ratchet wrench head.

[0013] As a further description of the above technical solution:

[0014] The folding connector includes two sets of connecting cylinders, with an ear fixedly connected to the outer side of the connecting cylinder and tangent to the outer surface of the connecting cylinder, and the corresponding ears of the two sets of connecting cylinders are hinged together.

[0015] As a further description of the above technical solution:

[0016] The spring seat rod inside the torque adjustment section is integrally set with the upper part of the reminder component, and the drive rod inside the main body section is integrally set with the lower part of the reminder component.

[0017] As a further description of the above technical solution:

[0018] One of the connecting cylinders is fixedly connected to the outer shell of the main body section, and the other connecting cylinder is rotatably connected to the outer shell of the torque adjustment section;

[0019] The lower part of the reminder piece is rotatably installed on the end of the drive rod inside the main section, and the upper part of the reminder piece is fixedly installed on the end of the spring seat rod inside the torque adjustment section.

[0020] As a further description of the above technical solution:

[0021] The spring seat rod inside the torque adjustment section is integrated with the upper part of the reminder piece.

[0022] As a further description of the above technical solution:

[0024] The beneficial effects of this utility model are:

[0025] In this invention, the control component is divided into a main body section and a torque adjustment section along the reminder part of the control component. The outer shell of the main body section and the outer shell of the torque adjustment section are hinged by a folding connector, so that the control component can be folded up along the folding connector. This makes the portable steel grid torque detection device shorter and smaller than the traditional torque wrench, making it easier to carry at high altitudes. Attached Figure Description

[0034] Please refer to the attached document. Figures 1-4 This application illustrates a portable steel space frame torque detection device provided in an embodiment of the present application. It can be used in the installation and maintenance of steel space frames and is easy to carry and use at high altitudes. It includes: a control component and a ratchet wrench head 6, with the ratchet wrench head 6 installed at one end of the control component.

[0035] The control mechanism is divided into a main body section 5 and a torque adjustment section 4 along the warning section of the control mechanism; as shown... Figure 5 As shown, the reminder part of the conventional control component adopts a three-section structure, with the outer side being an integral shell. The improved division in this application is to cut the shell part into two ends, and to hinge the shell of the main body section 5 to the shell of the torque adjustment section 4 through the folding connector 3.

[0036] The operating component of this application can be folded in three places along the folding connector, making the portable steel grid torque detection device shorter and smaller than the traditional torque wrench, making it easier to carry at heights.

[0037] The hinge axis of the folding connector 3 is parallel to the working surface of the ratchet wrench head 6, and the folding direction of the outer shell of the main body section 5 and the outer shell of the torque adjustment section 4 is perpendicular to the hinge axis. With this design, when in use, the force exerted by the user to rotate the ratchet wrench head 6 is always perpendicular to the folding direction of the outer shell of the main body section 5 and the outer shell of the torque adjustment section 4. Therefore, when in use, the hinge between the main body section 5 and the torque adjustment section 4 has no effect on the transmission of torque between the main body section 5 and the torque adjustment section 4.

[0038] The lower part 2 of the reminder is installed at the end of the drive rod inside the main body section 5, and the upper part 1 of the reminder is installed at the end of the spring seat rod inside the torque adjustment section 4. The lower part 2 of the reminder and the upper part 1 of the reminder are wedge-shaped, and the wedge-shaped mating surface is perpendicular to the working surface of the ratchet wrench head 6.

[0039] It is worth noting that the improvements in this application are only in the housing of the control component and the mating structure between the drive rod and the spring seat rod (the conventional drive rod and spring seat rod are...). Figure 5 The structure shown is a three-section structure, and the rest of the structure is the same as that of existing torque wrenches.

[0040] Please refer to the following when using it. Figures 1-4The user operates the torque adjustment section 4 on the right to rotate. Since the hinge axis of the folding connector 3 is parallel to the working surface of the ratchet wrench head 6, the torsional force of the torque adjustment section 4 is directly transmitted to the main body section 5, and the main body section 5 and the torque adjustment section 4 rotate synchronously. The ratchet wrench head 6 is hinged to the outer shell of the main body section 5, and the ratchet wrench head 6 is fixedly connected to the drive rod inside the main body section 5. In the early stage of tightening, the spring seat rod rotates synchronously with the torque adjustment section 4, and with the lower part 2 and the upper part 1 of the reminder piece in a wedge fit, the drive rod is driven to rotate. The drive rod drives the ratchet wrench head 6 to rotate. When the bolt reaches the pre-tightening force, the fit structure between the lower part 2 and the upper part 1 of the reminder piece disengages, and the end of the drive rod hits the inner wall of the main body section 5, producing a warning sound.

[0041] In one embodiment, the folding connector 3 includes: two sets of connecting cylinders, with ears tangent to the outer surface of the connecting cylinders fixedly connected to the outer side of the connecting cylinders, and the ears of the two sets of connecting cylinders being hinged to each other.

[0042] This structural design allows the two sets of connecting cylinders to rotate relative to each other by a large angle of 180°, making the two sets of connecting cylinders parallel. Specifically, this is reflected in the main body section 5 and the torque adjustment section 4, where the main body section 5 and the torque adjustment section 4 appear to be folded together.

[0043] In one embodiment, the spring seat rod inside the torque adjustment section 4 is integrally set with the upper part 1 of the reminder, and the drive rod inside the main body section 5 is integrally set with the lower part 2 of the reminder, making the transmission of the integral structure more stable.

[0044] The wedge-shaped fit between the lower part 2 and the upper part 1 of the reminder piece can only transmit unidirectional force and can adapt to the clockwise tightening process, but the bolts tightened counterclockwise will not be usable (generally, torque wrenches are only used to tighten bolts and are prohibited from being used to disassemble bolts). In this application, one of the connecting cylinders is fixedly connected to the outer shell of the main body section 5, and the other connecting cylinder is rotatably connected to the outer shell of the torque adjustment section 4; the lower part 2 of the reminder piece is rotatably installed at the end of the drive rod inside the main body section 5, and the upper part 1 of the reminder piece is fixedly installed at the end of the spring seat rod inside the torque adjustment section 4.

[0045] The user can rotate the torque adjustment section 4 by 180° when the control component is in the unfolded state, causing the internal spring seat rod to rotate. This causes the upper part 1 of the reminder component to rotate, and the upper part 1 of the reminder component drives the lower part 2 of the reminder component to rotate 180° relative to the drive rod. At this time, the mating surfaces of the upper part 1 and the lower part 2 of the reminder component can rotate 180°.

[0046] In one embodiment, the spring seat rod inside the torque adjustment section 4 is integrated with the upper part 1 of the reminder.

[0047] In one embodiment, the ends of the lower part 2 and the upper part 1 of the reminder are arc-shaped. Compared with the beveled surface, the arc-shaped mating surface makes it easier to disengage.

[0048] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
