Description

Technical Field

[0001] The utility model relates to a manual smoothing device, in particular to a semi-open manual smoothing device. Background Art

[0002] A manual flattener is a device that can flatten one end of a stainless steel bellows manually. In order to facilitate connection, a union nut is installed on the end of the stainless steel bellows. In order to prevent the union nut from falling off, a manual flattener is used to flatten the end of the stainless steel bellows to form an annular rib, which prevents the union nut from falling off from the end of the stainless steel bellows.

[0003] The traditional manual corrugator has a bayonet at one end, and a flap is hinged on one side of the bayonet. When the stainless steel corrugation needs to be smoothed, one end of the stainless steel bellows is first inserted into the bayonet. At this time, half of the end of the stainless steel bellows is restricted, and then the flap can be tightly closed on the bayonet. At this time, the other half of the end of the stainless steel bellows is restricted. When the outer periphery of the end of the stainless steel bellows is restricted, the smoothing head of the manual corrugator can be used to impact the stainless steel bellows, thereby flattening the end of the stainless steel bellows and forming an annular rib to complete the smoothing work. It can be seen that the dimensions of the bayonet and the flap are fixed, so only one size of stainless steel bellows can be smoothed. If another size of stainless steel bellows needs to be smoothed, the entire manual corrugator can only be replaced. This smoothing method is not only troublesome, but also leads to increased smoothing costs and waste of resources. Summary of the Invention

[0027] The upper and lower end surfaces of the front pressure plate 803 and the upper and lower end surfaces of the rear pressure plate 802 are all arc-shaped.

[0028] The outer wall of the housing 4 is provided with a plurality of anti-slip grooves 9 evenly distributed in the axial direction, and the anti-slip grooves 9 are annular.

[0029] A guide hole 10 communicating with the internal space of the shell 4 is provided at the center of the right end face, and the push rod 1 passes through the guide hole 10; an annular screw connection portion 11 extends to the left from the inner edge of the left end port of the shell 4; the right end of the limiting sleeve 5 is screwed to the outside of the screw connection portion 11.

[0031] The pressure-applying member is spherical.

[0032] The method of using the utility model is as follows:

[0033] When it is necessary to smooth the stainless steel corrugated pipe, the smoothing module can be pulled upward from the limit slot 7 through the bayonet 6. As the smoothing module loses the restriction of the inner wall of the limit slot 7, the front pressure plate 803 and the rear pressure plate 802 are separated under the elastic force of the spring 815. At this time, the front pressure plate 803 moves forward and the rear pressure plate 802 moves backward. When the front pressure plate 803 moves forward to a certain stroke, it is restricted by the front nut 818. When the rear pressure plate 802 moves backward to a certain stroke, it is restricted by the rear nut 819. At this time, the limiting hole 801 is divided into two, forming a front semicircular hole 804 and a rear semicircular hole 805, and the gap between the rear side wall of the front pressure plate 803 and the front side wall of the rear pressure plate 802 becomes larger. Since the diameter of each limiting hole 801 is different, after selecting the limiting hole 801 that is suitable for the current stainless steel corrugated pipe, The end of the stainless steel bellows can be placed into the gap between the rear side wall of the front pressure plate 803 and the front side wall of the rear pressure plate 802, so that it corresponds to the positions of the front semicircular hole 804 and the rear semicircular hole 805. Then the front pressure plate 803 and the rear pressure plate 802 can be brought close to each other by clenching a fist. At this moment, the spring 815 is compressed and generates elastic force. As the gap between the front pressure plate 803 and the rear pressure plate 802 continues to decrease, the front semicircular hole 804 and the rear semicircular hole 805 are combined to form a complete limiting hole 801. At this time, the stainless steel bellows is located in the limiting hole 801, and the locking part 808 formed by the front limiting part 806 and the rear limiting part 807 is locked in the gap between the adjacent corrugations on the stainless steel bellows, effectively limiting the end of the stainless steel bellows on the smoothing module.

[0034] When the end of the stainless steel bellows is restricted and fixed on the smoothing module, the end of the smoothing module can be inserted into the limiting groove 7, and the left and right groove walls of the limiting groove 7 limit the left and right movement of the front pressure plate 803 and the rear pressure plate 802. At the same time, the rear side groove wall of the limiting groove 7 presses the rear pressure plate 802 tightly against the rear side wall of the front pressure plate 803, and the front side groove wall of the limiting groove 7 presses the front pressure plate 803 tightly against the front side wall of the rear pressure plate 802, thereby ensuring the stability of the stainless steel bellows when the end is restricted in the limiting hole 801. After the end of the corrugated tube is restricted and fixed, the user can hold the shell 4 with one hand and the pressure piece 3 with the other hand, and push the push rod 1 to the left through the pressure piece 3. At this time, the push rod 1 will drive the flat wave head 2 to move to the left and impact the right end face of the stainless steel bellows. Under the obstruction of the locking portion 808 formed by the front limiting portion 806 and the rear limiting portion 807, the right end of the stainless steel bellows squeezed to the left can only deform outward, thereby squeezing the corrugations of the outer wall of the right end of the stainless steel bellows into a ring-shaped retaining edge to prevent the joint nut from falling off.

[0035] From the above, it can be seen that the smoothing module of the present invention has different limiting holes 801, and the diameter of each limiting hole 801 is different. One limiting hole 801 can limit a stainless steel bellows of one size. Therefore, when smoothing stainless steel bellows of different sizes, there is no need to replace the entire manual smoother. It is only necessary to insert the stainless steel bellows into the limiting hole 801 that is adapted to its size, and then the end of the stainless steel bellows can be smoothed by the smoothing head 2, which effectively reduces the trouble of replacing manual smoothers of different models. At the same time, there is no need to purchase different models of manual smoothers to adapt to stainless steel bellows of different sizes, which effectively reduces the smoothing cost and can effectively avoid the situation where a large number of manual smoothers are placed together, resulting in a large space.

[0036] There are two limiting holes 801. The front semicircular hole 804 is arranged on the upper and lower sides of the rear side wall of the front pressure plate 803, and the rear semicircular hole 805 is arranged on the upper and lower sides of the front side wall of the rear pressure plate 802. This structural design makes it easy to press the front pressure plate 803 and the rear pressure plate 802 at the same time with one hand, so that the front pressure plate 803 and the rear pressure plate 802 are close to each other and fit together.

[0037] The upper and lower end surfaces of the front pressure plate 803 and the upper and lower end surfaces of the rear pressure plate 802 are all arc-shaped. This structural design enables the upper and lower ends of the smoothing module to be quickly inserted into the limiting groove 7 through the bayonet 6, thereby achieving rapid positioning of the smoothing module.

[0038] The outer wall of the shell 4 is provided with a number of anti-slip grooves 9 which are evenly distributed axially. The anti-slip grooves 9 are annular. The presence of the anti-slip grooves 9 can effectively increase the friction between the hand and the outer wall of the shell 4, ensuring that the user can hold the shell 4 firmly when smoothing the wave.

[0039] A guide hole 10 communicating with the internal space of the shell 4 is provided at the center of the right end face. The push rod 1 passes through the guide hole 10. The existence of the guide hole 10 can play a guiding role when the push rod drives the flat wave head 2 to move, thereby ensuring the stability of the flat wave head 2 when moving.

[0040] An annular threaded portion 11 extends leftward from the inner edge of the left end of the shell 4 , and the right end of the limiting sleeve 5 is threadedly connected to the outside of the threaded portion 11 . This fixing method facilitates assembly and disassembly between the shell 4 and the limiting sleeve 5 .

[0041] A left threaded hole 12 is provided at the center of the right end face of the flat wave head 2, a left threaded joint 13 is provided at the center of the left end face of the push rod 1, which is threaded into the left threaded hole 12, a right threaded hole 14 is provided at the center of the left end face of the pressure member 3, and a right threaded joint 15 is provided at the center of the right end face of the push rod 1, which is threaded into the right threaded hole 14. This structural design facilitates disassembly and assembly between the pressure member 3 and the push rod 1, and between the flat wave head 2 and the push rod 1, thereby facilitating the replacement of the pressure member 3 and the flat wave head 2.

[0042] The pressure member 3 is spherical, which not only provides a point of force for the user to apply pressure, but also utilizes the spherical surface of the pressure member 3 to ensure the comfort of the user when pushing with his hands.
