To protect the heat shrink tubing, a protective sleeve is then placed over it at a corresponding position. The protective sleeve is initially attached... Figure 6 The open position shown requires the operator to press the upper semicircular sleeve of the protective sleeve downwards to clamp the upper and lower semicircular sleeves together. The clamped state is shown in the attached figure. Figure 5 As shown, this method results in high labor costs, long manual operation time, low efficiency, and the problem of the protective cover not being clamped tightly. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heating tube protective sleeve clamping device that is simple in structure, easy to operate, and saves manpower and time.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A heating tube protective sleeve clamping device, characterized in that: it includes a bracket, a linear drive mechanism, an upper mold and a lower mold, the lower mold is fixed on the bracket, the upper mold is located above the lower mold and one end is hinged to the lower mold, one end of the linear drive mechanism is hinged to the bracket and the other end is hinged to the upper mold, the linear drive mechanism drives the upper mold to press down to lock the protective sleeve on the lower mold.

[0006] The upper mold can be opened and lowered by a linear drive mechanism. When the upper mold is lowered, the protective sleeve on the lower mold can be locked. The structure is simple, the operation is convenient, and it saves manpower and time.

[0007] The protective sleeve of this utility model includes an upper semicircular sleeve, a lower semicircular sleeve, and a connecting section. The upper and lower semicircular sleeves are arranged vertically opposite each other, with the opening of the upper semicircular sleeve facing downwards and the opening of the lower semicircular sleeve facing upwards. The left end of the upper semicircular sleeve is connected to the left end of the lower semicircular sleeve via the connecting section. When the upper semicircular sleeve is pressed down, the right end of the upper semicircular sleeve is locked to the right end of the lower semicircular sleeve. The lower semicircular sleeve of the protective sleeve is stuck outside the heating tube. Then, the upper semicircular sleeve is pressed down, so that the right ends of the upper and lower semicircular sleeves are locked, thereby clamping the protective sleeve onto the heating tube.

[0008] The upper semicircular sleeve of this invention has a locking hook fixed at its right end, and the lower semicircular sleeve extends to the right to form a right end face that cooperates with the locking hook. When the upper semicircular sleeve is pressed down, the locking hook hooks the right end face of the lower semicircular sleeve.

[0009] The upper semicircular sleeve of this invention extends to the right at its right end to form an upper right locking surface, and the lower semicircular sleeve extends to the right at its right end to form a lower right locking surface. One of the lower end of the upper right locking surface and the upper end of the lower right locking surface is provided with a limiting protrusion, and the other is provided with a limiting groove. The limiting protrusion and the limiting groove are tightly fitted together to achieve the protective sleeve being clamped on the heating tube.

[0010] The lower mold of this utility model has a lower semicircular groove that runs through it along its length. The upper surface of the lower mold forms a left contact end face on the left side of the lower semicircular groove and a right contact end face on the right side of the lower semicircular groove.

[0011] The upper mold has an upper semicircular groove that runs through it along its length. The lower surface of the upper mold forms a left pressing end face on the left side of the upper semicircular groove and a right pressing end face on the right side of the upper semicircular groove.

[0012] Place the protective sleeve on the lower semicircular groove of the lower mold. Insert the lower semicircular sleeve into the lower semicircular groove. Place the connecting section on the left contact end face and the right end face on the right contact end face. When the upper mold is pressed down, the upper semicircular sleeve of the protective sleeve enters the upper semicircular groove of the upper mold. The upper mold presses down and drives the upper semicircular sleeve downward. The left pressing end face of the upper mold presses the connecting section tightly, and the right pressing end face drives the locking hook downward to hook the right end face, thereby locking the protective sleeve.

[0013] The width of the right contact end face of the lower mold described in this utility model is smaller than the width of the right end face of the lower semicircular sleeve; so that when the locking hook is pressed down, it can hook onto the lower surface of the right end face, ensuring the locking effect of the protective sleeve.

[0014] The bracket of this utility model includes a base plate and a side plate. The side plate is fixed on the base plate, and the side plate and the base plate are L-shaped. The lower mold is fixed on the side plate.

[0015] The present invention has a connecting ear plate 1 fixed on the base plate and a connecting ear plate 2 fixed on the upper mold. One end of the linear drive mechanism is hinged to the connecting ear plate 1 via a rotating shaft 1, and the other end is hinged to the connecting ear plate 2 via a rotating shaft 2; so as to realize that the linear motion of the linear drive mechanism can drive the upper mold to open and close.

[0016] The connecting ear plate 2 of this utility model is fixed to the top of the upper mold.

[0017] The linear drive mechanism described in this utility model uses a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0018] The beneficial effects of this utility model are as follows: the upper mold can be opened and pressed down by the linear drive mechanism. When the upper mold is pressed down, the protective sleeve on the lower mold can be locked. The structure is simple, the operation is convenient, and it saves manpower and time.

[0030] The present invention will now be described in conjunction with the accompanying drawings and embodiments.

[0031] As shown in the attached figure, a heating tube protective sleeve clamping device includes a bracket, a linear drive mechanism, an upper mold 201 and a lower mold 202. The lower mold 202 is fixed on the bracket. The upper mold 201 is located above the lower mold 202 and is hinged to the lower mold 202 at one end. One end of the linear drive mechanism is hinged to the bracket and the other end is hinged to the upper mold 201. The linear drive mechanism drives the upper mold 201 to press down and lock the protective sleeve 5 on the lower mold 202.

[0032] The upper mold 201 can be opened and pressed down by a linear drive mechanism. When the upper mold 201 is pressed down, the protective sleeve 5 on the lower mold 202 can be locked. The structure is simple, the operation is convenient, and it saves manpower and time.

[0033] The protective sleeve 5 includes an upper semicircular sleeve 501, a lower semicircular sleeve 502, and a connecting section 503. The upper semicircular sleeve 501 and the lower semicircular sleeve 502 are arranged vertically opposite each other, with the opening of the upper semicircular sleeve 501 facing downwards and the opening of the lower semicircular sleeve 502 facing upwards. The left end of the upper semicircular sleeve 501 and the left end of the lower semicircular sleeve 502 are connected by the connecting section 503. When the upper semicircular sleeve 501 is pressed down, the right end of the upper semicircular sleeve 501 and the right end of the lower semicircular sleeve 502 are locked together. The lower semicircular sleeve 502 of the protective sleeve 5 is stuck outside the heating tube. Then, the upper semicircular sleeve 501 is pressed down, so that the right ends of the upper semicircular sleeve 501 and the lower semicircular sleeve 502 are locked together, thereby clamping the protective sleeve 5 onto the heating tube.

[0034] In this embodiment, the right end of the upper semicircular sleeve 501 is fixed with a locking hook 504, and the right end of the lower semicircular sleeve 502 extends to the right to form a right end face 505 that cooperates with the locking hook 504. When the upper semicircular sleeve 501 is pressed down, the locking hook 504 hooks the right end face 505 of the lower semicircular sleeve 502. The locking structure of the upper and lower semicircular sleeves is not limited to this. The right end of the upper semicircular sleeve 501 can also extend to the right to form an upper right locking surface, and the right end of the lower semicircular sleeve 502 can extend to the right to form a lower right locking surface. One of the lower end of the upper right locking surface and the upper end of the lower right locking surface is provided with a limiting protrusion, and the other is provided with a limiting groove. The limiting protrusion and the limiting groove are inserted tightly to achieve the protective sleeve 5 being clamped on the heating tube.

[0035] The lower mold 202 has a lower semi-circular groove 2021 that extends through it along its length. The upper surface of the lower mold 201 forms a left contact end face 2022 on the left side of the lower semi-circular groove 2021 and a right contact end face 2023 on the right side of the lower semi-circular groove 2021.

[0036] The upper mold 201 has an upper semi-circular groove 2011 that extends through its length. The lower surface of the upper mold 201 forms a left pressing end face 2012 on the left side of the upper semi-circular groove 2011 and a right pressing end face 2013 on the right side of the upper semi-circular groove 2011.

[0037] The protective sleeve 5 is placed on the lower semicircular groove 2021 of the lower mold 202. The lower semicircular sleeve 502 of the protective sleeve 5 is inserted into the lower semicircular groove 2021. The connecting section 503 is placed on the left contact end face 2022, and the right end face 505 is placed on the right contact end face 2023. When the upper mold 201 is pressed down, the upper semicircular sleeve 501 of the protective sleeve 5 enters the upper semicircular groove 2011 of the upper mold 201. The upper mold 201 presses down and drives the upper semicircular sleeve 501 downward. The left pressing end face 2012 of the upper mold 201 presses the connecting section 503 tightly, and the right pressing end face 2013 drives the locking hook 504 downward to hook the right end face 505, thereby locking the protective sleeve 5.

[0038] In this embodiment, the radius of the upper semicircular groove 2011 of the upper mold 201 is matched with the radius of the upper semicircular sleeve 501 of the protective sleeve 5, and the radius of the lower semicircular groove 2021 of the lower mold 202 is matched with the radius of the lower semicircular sleeve 502 of the protective sleeve 5.

[0039] The width of the right contact end face 2023 of the lower mold 202 is smaller than the width of the right end face 505 of the lower semicircular sleeve 502; so that when the locking hook 504 is pressed down, it can hook onto the lower surface of the right end face 505, ensuring the locking effect of the protective sleeve 5; in this embodiment, an L-shaped notch 2024 is provided on the right edge of the upper surface of the lower mold 202 along its length direction; so that the width of the right contact end face 2023 of the lower mold 202 is smaller than the width of the right end face 505 of the protective sleeve, and the tip of the locking hook 504 can hook onto the lower surface of the right end face 505, ensuring the locking of the protective sleeve 5.

[0040] The support includes a base plate 101 and a side plate 102. The side plate 102 is perpendicular to the base plate 101 and is fixed to the base plate 101. The side plate 102 and the base plate 101 are L-shaped. The lower mold 202 is fixed to the top of the side plate 102.

[0041] A connecting ear plate 401 is fixed on the base plate 101, and a connecting ear plate 402 is fixed on the upper mold 201. The housing end of the linear drive mechanism is hinged to the connecting ear plate 401 via a rotating shaft, and the push rod end is hinged to the connecting ear plate 402 via a rotating shaft; so that the linear motion of the linear drive mechanism can drive the upper mold to open and close.

[0042] The connecting ear plate 402 is fixed to the top of the upper mold 201, which facilitates the opening and closing of the upper mold under the drive of the linear drive mechanism.

[0043] The linear drive mechanism adopts a pneumatic cylinder, hydraulic cylinder, or electric push rod. In this embodiment, the linear drive mechanism adopts a pneumatic cylinder 3. The pneumatic cylinder 3 can be a manual cylinder or an automatic cylinder, depending on the actual use requirements.
