[0026] As Figures 1 to 6As shown, the utility model discloses a kind of pressing locking structure of electric iron, including base 1 and the connecting plate 2 located at both sides of base 1, the lower end of connecting plate 2 is rotatably connected on base 1, that is, connecting plate 2 can rotate relative to base 1, the upper end between both sides connecting plate 2 is rotatably provided with rotating rod 3, rotating rod 3 is connected on handle 4, and rotating rod 3 is connected with tension cam 5, handle 4 rotation controls rotating rod 3 rotation, to drive tension cam 5 rotation;In the embodiment, as shown, Figures 2 to 4 As shown, rotating rod 3 is set to flat, and handle 4 is provided with flat assembly slot matched with the shape of rotating rod 3, so as to be matched and installed with rotating rod 3 and then locked;Compared with the design of rotating rod 3 into circular shape, flat can enhance the linkage of handle 4 and rotating rod 3, that is, handle 4 and rotating rod 3 are not easy to slip between, so that swinging handle 4 can well control rotating rod 3 rotation.

[0027] Tension cam 5 is connected with one end of pull rod 11, and the other end of pull rod 11 is connected with cam arm 6;Further comprising connecting shaft 7, both ends of connecting shaft 7 are connected on connecting plate 2, and the middle part of cam arm 6 is rotatably connected on connecting shaft 7;The lower end of cam arm 6 is connected with a elastic tension component 8;Base 1 is provided with track groove 9 at the position corresponding to elastic tension component 8, and the lower end of elastic tension component 8 is slidably connected with track groove 9.

[0028] As shown, Figure 5 Elastic tension component 8 includes outer cylinder 801, inner rod 802 and sliding seat 803, and inner rod 802 is slidably connected in outer cylinder 801;Cam arm 6 has lower end face 601, and outer cylinder 801 is connected with lower end face 601;Sliding seat 803 has upper end face 8031, and inner rod 802 is connected with upper end face 8031;Spring 804 is sleeved outside outer cylinder 801, the upper end of spring 804 abuts against the lower end face 601 of cam arm 6, and the upper end of spring 804 abuts against the upper end face 8031 of sliding seat 803;Therefore, inner rod 802 can be pulled in outer cylinder 801, and spring 804 can reset the position between inner rod 802 and outer cylinder 801.

[0029] Both sides of sliding seat 803 are provided with bearing 805, and bearing 805 is rollingly connected on track groove 9, so that the lower end of elastic tension component 8 (sliding seat 803) can be connected on track groove 9 in a rolling manner, with small friction and smooth movement.

[0030] From Figure 3 And Figure 4As can be seen, the track groove 9 is a curved arc surface. Point A is the lowest point where the lower end of the elastic tensioning component 8 (bearing 805 on the slide 803) contacts the track groove 9, and point B is the highest point where the lower end of the elastic tensioning component 8 (bearing 805 on the slide 803) contacts the track groove 9. Therefore, the distance between the track groove 9 and the connecting shaft 7 gradually decreases from point A to point B. That is, the higher the track groove 9 goes, the closer it gets to the connecting shaft 7. Thus, when the lower end of the elastic tensioning component 8 moves from point A to point B, the spring 804 is in a state of gradual compression, and the spring 804's pressure on the cam arm 6 gradually increases. When the lower end of the elastic tensioning component 8 moves from point B to point A, the spring 804 is in a state of gradual recovery and extension, and the spring 804's pressure on the cam arm 6 gradually decreases.

The protruding edge 8021 is slidably fitted into the groove 8011. The protruding edge 8021 and the groove 8011 are designed so that when the inner rod 802 slides on the outer cylinder 801, the two will not rotate relative to each other in the radial direction, that is, at least ensure that the slide block 803 will not twist, thereby allowing the bearing 805 to slide stably along the track groove 9.

[0032] It also includes a mounting cover 10, in which the track groove 9 is fixed; the mounting cover 10 is provided with a limiting edge 1001 around its perimeter, and the mounting cover 10 is fixedly mounted on the base 1 by means of the limiting edge 1001, and can be fixed on the base 1 by screws screwed into the limiting edge 1001.

[0033] like Figure 6 The diagram illustrates the specific function of an electric iron with a locking mechanism installed. The electric iron includes a base 12 and an upper housing 13 hinged to the base 12. The base 1 is fixedly connected to the base 12, and the handle 4 is connected to the upper housing 13. The base 12 has a lower ironing plate, and the upper housing 13 has an upper ironing plate. Clothes are placed on the lower ironing plate, and the upper housing 13 is controlled to swing downwards, causing the upper ironing plate to press against the lower ironing plate for ironing. First, by pulling the handle 4 downwards, the upper housing 13 swings, causing the upper ironing plate of the upper housing 13 to press against the lower ironing plate of the base 12 for ironing. Then, by turning the handle 4 downwards, the rotating rod 3 and the pulling cam 5 rotate, thereby pulling the pull rod 11 forward, causing the cam arm 6 to swing forward, ultimately causing the elastic tensioning component 8 to... Figure 3 State transition to Figure 4The state; from the above description, the spring 804 is in a compressed state at this time, thereby resisting the cam arm 6, that is, the handle 4 is locked, and the operator will not rotate the handle 4, thereby avoiding fatigue. When the ironing time is enough, the handle 4 is turned upward, the rotating rod 3 and the tension cam 5 are rotated, the pull rod 11 is pushed backward, and finally the elastic tension component 8 is turned to the Figure 4 state from the Figure 3 state, that is, the cam arm 6 is no longer resisted, and then the handle 4 is lifted upward, the upper box 13 is turned upward, that is, the upper ironing plate is separated from the lower ironing plate, and the clothes can be taken away.

[0034] From the Figure 1 embodiment, the handle 4 is arranged in a ring shape, so that multiple parts of the handle 4 can be controlled, and use is convenient.

[0035] From the Figure 1 and Figure 2 embodiment, the number of the pull rod 11 is two, which are connected to the two sides of the tension cam 5 and the cam arm 6, so that the two sides of the tension cam 5 and the cam arm 6 can be stressed when acting, the stress is uniform, and operation is stable.

[0036] The utility model provides a kind of compression locking structure of electric iron, to make the handle 4 be locked when the upper ironing plate in electric iron is pressed on the lower ironing plate to iron clothes, without operator keeping the handle 4 has the depression force and leading to tired and sore, can free hands, use is convenient, structure is ingenious.

[0037] Finally, it should be pointed out that: the above is only preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the embodiment, for the person skilled in the art, it can still modify the technical scheme recorded in each embodiment, or equivalent replacement to part of technical features, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
