Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1-5 This utility model provides an adjustable nozzle structure, comprising:

[0030] Mounting plate 1, with a connecting seat 2 fixedly connected to one side, and a support seat 3 slidably connected to the side of the connecting seat 2 away from mounting plate 1;

[0031] The nozzle 4 is fixedly connected to a ball joint 5 on the side near the support base 3. The support base 3 has a ball joint groove on the side extending out of the connecting seat 2 that is movable to the ball joint 5. The ball joint 5 has a through hole in the center, and the two ends of the through hole are connected to the connecting seat 2 and the nozzle 4 respectively.

[0032] Four connecting plates 6, a support plate 7 is fixed to the outer periphery of the nozzle 4, and a connecting block 8 is respectively connected to the four sides of the support plate 7. The four connecting plates 6 are hinged to the four connecting blocks 8 in a corresponding manner, and the end of the connecting plate 6 away from the nozzle 4 is hinged to the connecting seat 2.

[0033] The locking assembly includes several locking plates 9 that are elastically slidably attached to the connecting seat 2. The locking plates 9 are arranged in a one-to-one correspondence with the connecting plates 6. The connecting seat 2 is provided with a pressing member, and the pressing end of the pressing member is connected to the locking plate 9 so that the nozzle 4 has a switchable fixed or movable state relative to the ball joint groove.

[0034] This invention uses a ball joint 5 and a ball joint groove to mount the nozzle 4 on the support base 3, allowing the nozzle 4 to flexibly adjust its angle relative to the support base 3. Furthermore, by fixing the support plate 7 to the nozzle 4 and hinged four connecting plates 6 to connecting blocks 8, which are rotatably connected to the four sides of the support plate 7, the connecting plates 6 can be flexibly adjusted relative to the support plate 7. The connecting plates 6 are hinged to the connecting base 2, and the locking assembly on the connecting base 2 controls the connection plates 6, allowing switching between fixed and movable states. This maintains the stability of the nozzle 4 angle. The nozzle 4 angle adjustment method is also simpler. The pressing end of the pressing member is connected to the clamping plate 9, and the clamping plate 9 is arranged one-to-one with the connecting plate 6. Thus, the connecting plates 6 and clamping plates 9 are hinged one-to-one. By simply adjusting the state of the clamping plate 9 with the pressing member, the connecting plate 6 can be moved or fixed relative to the connecting base 2, effectively achieving simple and flexible adjustment of the nozzle 4 angle and improving the stability of the nozzle 4.

[0035] Furthermore, the pressing element includes:

[0036] Several pressing plates 10 are fixed to the side of the support base 3 near the connecting base 2, and the pressing plates 10 and the clamping plates 9 are arranged in a one-to-one correspondence.

[0037] A pair of support plates 11 are arranged opposite each other on both sides of the pressing plate 10. The support plates 11 are fixedly connected to the clamping plate 9 and slidably connected to the connecting seat 2. The support plates 11 have an elastic tendency to move outward along the center of the connecting seat 2. A top rod 12 is fixedly connected between the pair of support plates 11. The pressing plate 10 has an inclined edge on the side near the top rod 12. The inclined edge slides in contact with the top rod 12 so that the support plates 11 slide along the center direction of the connecting seat 2.

[0038] Specifically, by sliding the support base 3 and the connecting base 2 together, and fixing the pressing plate 10 to the support base 3, that is, the pressing plate 10 and the connecting base 2 are slidably connected, and the pressing plate 10 corresponds one-to-one with the clamping plate 9. The support plate 11 connects the top rod 12 to the pressing plate 10 one-to-one, and the top rod 12 and the clamping plate 9 are relatively fixed. The inclined side of the pressing plate 10 is used to press the top rod 12, so that the support plate 11 drives the clamping plate 9 to slide towards the center of the connecting base 2, thereby realizing the switching of the connection state between the clamping plate 9 and the connecting plate 6. Moreover, the support plate 11 has an elastic tendency to move away from the center of the connecting base 2. Therefore, when it is necessary to adjust the angle of the nozzle 4, it is only necessary to press the support base 3 along the direction of the connecting base 2, so that the connecting plates 6 and the connecting base 2 can move. At this time, the angle can be adjusted by rotating the nozzle 4. After releasing the nozzle 4, the elastic tendency of the support plate 11 fixes the clamping plate 9 and the connecting plate 6, and can stabilize the nozzle 4.

[0039] Furthermore, the support plate 11 has a T-shaped structure, and a T-shaped groove is provided in the connecting seat 2. The support plate 11 slides in the T-shaped groove, and the long side of the support plate 11 extends out of the T-shaped groove and is fixedly connected to the clamping plate 9. The two sides of the support plate 11 are respectively fixedly connected to the two ends of the spring 13 between the inner sidewall of the opposite T-shaped groove.

[0040] The support plate 11 is slidably connected to the connecting seat 2 by the T-shaped groove opened in the connecting seat 2. The spring 13 provides elastic support to both sides of the support plate 11, so that the support plate 11 provides elastic force to the clamping plate 9. Under the premise that the top rod 12 does not exert external force, the connecting plate 6 is clamped and fixed by the clamping plate 9 to maintain the stability of the nozzle 4.

[0041] Furthermore, the outer wall of the connecting seat 2 is provided with several grooves, and the card plate 9 is slidably connected in the grooves one by one. The outer wall of the card plate 9 is provided with several slots along the axial direction. The inner wall of the groove is provided with a limiting groove on the opposite side. The limiting block 15 is slidably connected in the limiting groove. The two limiting blocks 15 are fixedly connected between them. The card post 14 is engaged with or does not contact any of the slots.

[0042] Specifically, the locking post 14 can be engaged or not engaged with the locking groove, and the locking post 14 slides in the limiting groove. When the pressing plate 10 presses the top rod 12, the support plate 11 slides toward the center of the connecting seat 2, and the locking plate 9 slides into the groove to disengage the locking post 14 from the locking groove. At this time, the locking post 14 slides normally. When the pressing plate 10 is not pressed, the support plate 11 drives the locking plate 9 to slide away from the connecting seat 2, locking the locking post 14 into the locking groove, thereby locking and fixing the connecting plate 6.

[0043] Furthermore, a fixed seat 16 is connected to the side of the locking post 14 away from the connecting seat 2. The fixed seat 16 has a connecting groove, and a rotating rod 17 is connected in the connecting groove. The end of the connecting plate 6 near the connecting seat 2 is fixed to the outer wall of the rotating rod 17.

[0044] Using the fixed base 16 and the rotating rod 17, the connecting plate 6 is hinged to the fixed base 16, and the fixed base 16 is rotated to the locking post 14, so as to realize the flexible rotation of the connecting plate 6 and ensure the effect of adjusting the angle of the nozzle 4.

[0045] Understandably, the rotation direction of the fixed seat 16 and the locking pin 14 is perpendicular to the rotation direction of the connecting plate 6 and the fixed seat 16. Similarly, the rotation direction of the connecting plate 6 and the connecting block 8 is perpendicular to the rotation direction of the connecting block 8 and the support plate 7.

[0046] Furthermore, the outer side wall of the support base 3 is circumferentially fixed with several locking protrusions 18, and the connecting base 2 is provided with a sliding groove corresponding to the locking protrusions 18. The locking protrusions 18 are limited and slidably connected in the sliding groove, and the sliding distance of the locking plate 9 in the groove is less than the sliding distance of the locking protrusions 18 in the sliding groove.

[0047] By fixing the locking protrusion 18 to the outer periphery of the support base 3, the support base 3 and the connecting base 2 are limited and slidably connected, and the locking plate 9 can be guaranteed to have sufficient sliding distance so that the locking post 14 can be engaged or disengaged from the locking groove.

[0048] Furthermore, a connecting pipe 19 runs through the center of the support plate 7, and the two ends of the connecting pipe 19 are respectively connected and fixed to the ball joint 5 and the nozzle 4.

[0049] Furthermore, the cross-section of the connecting seat 2 is one of a square, a regular hexagon, or a regular octagon, and the width of the connecting seat 2 gradually decreases along the direction toward the support seat 3.

[0050] By gradually reducing the size of the end of the connecting seat 2 near the support seat 3, space can be provided for the rotation of the connecting plate 6 when adjusting the angle of the nozzle 4, thus ensuring the structural rationality of the nozzle 4 angle adjustment.

[0051] This utility model provides a working principle for an adjustable nozzle structure:

[0052] By pressing the support base 3, the support base 3 drives the pressing plate 10 to squeeze the top rod 12, causing the top rod 12 to move the support plate 11 and squeeze the spring 13 until the locking post 14 disengages from the slot. At this time, rotate the nozzle 4 to adjust the angle. The connecting plate 6 and the connecting block 8 are hinged, and the connecting block 8 is rotated with the support plate 7, so that the connecting plate 6 can rotate with the nozzle 4 and drive the connected locking post 14 to slide along the limiting groove. After adjusting the angle of the nozzle 4, simply release the hand spring 13 to pop out the locking plate 9, so that the locking post 14 engages with the slot, fix the connecting plate 6 and the connecting seat 2, and stabilize the angle of the nozzle 4.

[0053] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
