[0030] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0031] Reference Figures 1 to 7 .
[0032] Embodiment 1 further illustrates a handle type torsion spring assembly and connection tooling proposed by the utility model.
[0033] A handle type torsion spring assembly and connection tool comprises a workbench 4. A strip-shaped slot 7 and a limit slot 8 are provided on the surface of the workbench 4. The strip-shaped slot 7 matches with the torsion spring force arm, and the limit slot 8 is used to accommodate the torsion spring coil.
[0034] It also includes a sleeve 2, and the end surface of the sleeve 2 that matches the workbench 4 is provided with a hollow structure for accommodating a torsion spring coil. The end surface of the sleeve 2 that matches the workbench 4 is provided with a first notch 5 and a second notch 6, and the first notch 5 and the second notch 6 both match the torsion spring force arm.
[0035] The staff places the torsion spring coil vertically inside the limiting groove 8 of the workbench 4, and at the same time makes the lower torsion spring force arm located inside the strip slot 7. The staff moves the sleeve 2 from top to bottom to cover the torsion spring coil, and makes the upper torsion spring force arm located inside the second slot 6. The staff manually rotates the sleeve 2. Since the lower torsion spring force arm is located inside the strip slot 7 and the upper torsion spring force arm is located inside the second slot 6, the torsion spring is in a rotational compression state during the rotation of the sleeve 2. When the first slot 5 is located directly above the lower torsion spring force arm, the staff presses the sleeve 2 downward to achieve that the lower torsion spring force arm is located inside the first slot 5. Since the torsion spring is in a rotational compression state as a whole, the torsion spring is stuck inside the hollow structure of the sleeve 2, that is, the torsion spring is assembled inside the sleeve 2.
[0036] The staff manually moves the sleeve 2, and the torsion spring is moved during the movement of the moving sleeve 2, and the torsion spring is moved to the position where it needs to be installed, and the two force arms of the torsion spring are located at the corresponding installation positions, and the lower torsion spring force arm and the upper torsion spring force arm are pushed, so that the torsion spring is moved from the inside of the sleeve 2 and installed at the position where it needs to be installed. Therefore, there is no need for the staff to manually squeeze the upper torsion spring force arm and the lower torsion spring force arm and then place the torsion spring at the position where it needs to be installed, that is, this tooling makes it easy to install the torsion spring at the position where it needs to be installed.
[0037] Embodiment 2 adds the following technical features based on Embodiment 1:
[0038] A handle-type torsion spring assembly and connection tool also includes a handle 1, an internal thread is provided at the end of the handle 1 relative to the sleeve 2, an annular thread plate 9 is fixedly connected to the end of the sleeve 2 relative to the handle 1, and an external thread is provided on the circumferential outer wall of the annular thread plate 9, and the external thread matches the internal thread.
[0039] Since the handle 1 is provided and the staff does not need to directly hold the sleeve 2, the staff can hold the handle 3 to operate. Since the external thread and the internal thread of the annular threaded plate 9 match, it is convenient to install the sleeve 2 on the handle 1.
[0040] Embodiment 3 adds the following technical features based on Embodiment 2:
[0041] A handle type torsion spring assembly connection tool, wherein a handle 3 is fixedly connected to the side wall of a handle 1.
[0042] Since the handle 3 is provided, when the sleeve 2 needs to be rotated, the staff only needs to manually rotate the handle 3. During the rotation of the handle 3, the sleeve 2 is rotated through the handle 1, thereby facilitating the rotation of the sleeve 2.
[0043] Embodiment 4 adds the following technical features on the basis of Embodiment 3:
[0044] A handle type torsion spring assembly and connection tool is disclosed, wherein a limiting block 10 is fixedly connected inside a limiting groove 8, and a diameter value of the limiting block 10 is smaller than an inner diameter value of a torsion spring coil.
[0045] Since the limiting block 10 is fixedly connected inside the limiting groove 8, the limiting block 10 is located inside the torsion spring coil when the torsion spring coil is placed inside the limiting groove 8. Therefore, the limiting block 10 facilitates the limiting of the torsion spring coil when the torsion spring coil is placed inside the limiting groove 8.
[0046] Embodiment 5 adds the following technical features on the basis of Embodiment 4:
[0047] A handle type torsion spring assembly and connection tool, further comprising:
[0048] The annular fixing plate 11 is fixedly connected to the outer side wall of the sleeve 2 .
[0049] The annular push plate 12 is located outside the sleeve 2 and is elastically connected to the annular fixing plate 11 .
[0050] The push rod 13 is fixedly connected to the annular push plate 12 , and the push rod 13 is movably arranged to penetrate the annular fixed plate 11 .
[0051] The push block 14 is fixedly connected to the push rod 13 . The push block 14 is provided in two pieces, one of which is located above the first notch 5 , and the other push block 14 is located above the second notch 6 .
[0052] A spring 16 is fixedly connected between the annular push plate 12 and the annular fixing plate 11 .
[0053] A push plate 17 is fixedly connected to the outer side wall of the annular push plate 12 .
[0054] A pushing groove 18 is formed on the side wall of the pushing block 14 .
[0055] The staff manually moves the sleeve 2, and the torsion spring is moved during the movement of the moving sleeve 2, and the torsion spring is moved to the position where it needs to be installed, and the two force arms of the torsion spring are located at the corresponding installation positions. The staff manually pushes the push plate 17, and the push block 14 is moved by the annular push plate 12 and the push rod 13 during the movement of the push plate 17. At this time, the spring 16 is in a compressed state. Since the two push blocks 14 are respectively located above the two force arms of the torsion spring, the push groove 18 is in contact with the torsion spring force arm during the movement of the push block 14, and the lower torsion spring force arm is moved out from the inside of the bar slot 7 and the upper torsion spring force arm is moved out from the inside of the second slot 6 during the movement of the push block 14, thereby realizing the torsion spring being moved from the inside of the sleeve 2 and installed at the position where it needs to be installed. Therefore, there is no need for the staff to manually squeeze the upper torsion spring force arm and the lower torsion spring force arm and then place the torsion spring at the position where it needs to be installed, that is, this tooling facilitates the installation of the torsion spring at the position where it needs to be installed.
[0056] Embodiment 6 adds the following technical features based on Embodiment 5:
[0057] A handle type torsion spring assembly connection tool, wherein a sleeve 2 is locked inside a limiting groove 8 of a workbench 4 by a locking bolt 19.
[0058] The workbench 4 and the sleeve 2 are both provided with threaded holes 15 matched with the locking bolts 19 .
[0059] When the tooling is not needed, the staff places the bottom of the sleeve 2 inside the limiting groove 8 and rotates the locking bolt 19 so that one end of the locking bolt 19 is threadedly connected to the inside of the threaded hole 15, that is, it is convenient to lock the sleeve 2 when the tooling is not used to prevent the sleeve 2 from rolling when it is placed directly on the upper surface of the workbench 4.
