[0036] In order to make the above objectives, characteristics and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] As shown in Figure 1 , Figures 3-7 , the present application provides a transmission mechanism, which comprises a base plate 1, and a rotating unit, a horizontal moving unit and a lifting unit arranged on the base plate 1, the rotating unit comprises a first push rod 9, the horizontal moving unit comprises a second push rod 10, and the lifting unit comprises a third push rod 11, a plurality of lug plates are arranged on the top of the base plate 1 in a horizontal direction, a transmission rod 2 is arranged in the lug plate, a first lug 4 is arranged on the middle part of the transmission rod 2, the first lug 4 comprises a sleeve part sleeved on the transmission rod 2 and a rotating part connected with the first push rod 9, that is, the rotation of the transmission rod 2 can be realized by pushing the first push rod 9, and a sliding groove 2-1 is symmetrically arranged on both ends of the transmission rod 2, a connecting pipe 3 is slidably connected on the sliding groove 2-1, and the connecting pipe 3 is axially limited by the sliding groove 2-1, so that the connecting pipe 3 can rotate together with the transmission rod 2.

[0038] Meanwhile, a first shaft sleeve 5 is sleeved on one end of the connecting pipe 3 close to the first lug 4, a second lug 6 is connected on the first shaft sleeve 5, two first connecting rods 7 are hingedly connected with one end of the second lug 6 located on both sides of the transmission rod 2, the other end of the two first connecting rods 7 is hingedly connected with one end of a second connecting rod 8 at a point, the second connecting rod 8 comprises a straight section and an inclined section, that is, the two first connecting rods 7 and the second connecting rod 8 form a scissor structure, the other end of the second connecting rod 8 is connected with the second push rod 10, by driving the second push rod 10, the second connecting rod 8 can move upward or downward, so as to drive the first connecting rod 7 to gather or spread, and push the first shaft sleeve 5 and the connecting pipe 3 to move horizontally along the sliding groove 2-1 of the transmission rod 2.

[0039] It should be noted that the first shaft sleeve 5 is connected with the connecting pipe 3 through bolts, which makes the first shaft sleeve 5 not to be displaced relative to the connecting pipe 3 when the first connecting rod 7 pushes the first shaft sleeve 5, that is, the first shaft sleeve 5 and the connecting pipe 3 can move horizontally synchronously, and further, one end of the first shaft sleeve 5 is provided with a protrusion 5-1 and the other end of the first shaft sleeve 5 is provided with a bolt hole 5-2, which makes the second hanging ear 6 sleeved in the middle part of the first shaft sleeve 5 not to be rotated with the connecting pipe 3 when the connecting pipe 3 is pushed to move horizontally, thereby avoiding the problem that the scissors structure is rotated with the connecting pipe 3, the scissors structure is turned up, and the horizontal movement and rotation of the connecting pipe 3 cannot be performed.

[0040] Further, the transmission mechanism can be applied to various devices, such as a pesticide spreader, a camera, etc., depending on the type of the execution element connected to the end of the connecting pipe 3 away from the first hanging ear 4 through the connecting piece.

[0041] Especially, it should be noted that the transmission mechanism of the present application only through the cooperation of the connecting pipe 3, the first shaft sleeve 5, the second hanging ear 6, the scissors structure and the second push rod 10, the two execution elements can be moved horizontally in opposite directions under the action of the second push rod 10, and if the prior art is used, two driving mechanisms need to be provided to realize the horizontal movement of the two execution elements in opposite directions, and the two driving mechanisms are arranged in the horizontal direction to push the execution elements to move horizontally, so that the transmission mechanism occupies a larger space in the horizontal direction. Obviously, the present application reduces the number of driving mechanisms required to realize the horizontal movement of the two execution elements in opposite directions, and at the same time reduces the space occupied by the transmission mechanism in the horizontal direction.

[0042] Further, by arranging the second connecting rod 8 with one end horizontal and one end inclined, the vertical slide rail 14 is arranged on the base plate 1, and the middle part of the second connecting rod 8 is slidably connected with the vertical slide rail 14 through a sliding block, so that the second push rod does not need to be arranged below the first connecting rod 7, and the horizontal movement of the two execution elements in opposite directions can be realized on one side of the first connecting rod 7, thereby reducing the space occupied by the transmission mechanism in the vertical direction, and further reducing the occupied space of the transmission mechanism.

[0043] Further, the middle part of the transmission rod in the present application is connected with the first push rod 9 arranged in the vertical direction through the first hanging ear 4, and the rotation of the two execution elements can be realized through the cooperation of the first push rod 9 and the first hanging ear 4, thereby avoiding the problem that in the prior art, the motor output end is connected with the transmission rod through a connecting rod to realize the rotation of the execution element, which results in a larger occupied space of the transmission mechanism in the horizontal direction, thereby further reducing the occupied space of the transmission mechanism and reducing the use cost of the transmission mechanism.

[0044] The present application also provides a shower system using the transmission mechanism, such as Figure 2As shown, the shower system includes a U-shaped support frame 16, which includes a top beam 16-1 and a middle beam 16-2. The third push rod 11 of the lifting unit extends downward and abuts against the middle beam 16-2, which can drive the base plate 1 and the other structures located on the base plate 1 to move up and down. Two sets of guide rails 17 are provided vertically between the top beam 16-1 and the middle beam 16-2 of the U-shaped support frame 16. The guide rails 17 cooperate with the sliders provided at the four corners of the base plate 1, so that when the base plate 1 is driven to move up and down by the third push rod 11, it can move along the guide rails 17, making the lifting and lowering movement of the transmission mechanism more stable.

[0045] Furthermore, when the shower system uses the aforementioned transmission mechanism, the end of the connecting pipe 3 away from the first hanging ear 4 is connected to the shower arm 15 via a connector. Thus, since the connecting pipe 3 can rotate, move horizontally, and move up and down under the action of the first push rod 9, the second push rod 10, and the third push rod 11 respectively, the shower arms 15 on both sides can also rotate, move horizontally, and move up and down with the connecting pipe 3.

A three-way water distribution valve 15-5 corresponding to the shower head 15-3 is provided on the back of the shower head 15-3, i.e., on the housing 15-1. The three-way water distribution valve 15-5 can be adjusted according to usage requirements. The three-way water distribution valve 15-5 and the water supply pipe are fixed together by clamps, effectively preventing water leakage.

[0048] The shower 15-3 is fixed between the fixed plate 15-2 through a plastic nylon nut, and the shower 15-3 is made according to the atomization effect principle, so that the sprayed hot water is in the form of water mist, the spraying range is improved while the spraying intensity is reduced, and the skin comfort is improved.

[0049] Moreover, compared with the traditional water storage type shower arm 15, the water supply pipe is arranged in the shower arm 15, so that water can be supplied during use, water storage is not needed, the weight is low, and the shower arm 15 has better heat insulation and waterproof performance because water storage is not needed in the shower arm 15.

[0050] In addition, the I-shaped support frame 16 is provided below the I-shaped support frame 16, and the I-shaped support frame 16 is more stable, and the I-shaped support frame 18 is provided below the I-shaped support frame 18, so that the shower system can be moved to different spaces according to the use condition.

[0051] The I-shaped support frame 16 and the I-shaped support frame 18 can be made of aluminum profiles.

[0052] It should be noted that the first push rod 9, the second push rod 10 and the third push rod 11 in the present application can be a manual push rod or an automatic push rod, and the automatic push rod can be a push rod driven by different types of driving devices such as hydraulic / pneumatic / electric, wherein the electric push rod adopts an industrial-grade electric push rod, the stroke of the electric push rod responsible for overall lifting is 300mm, the stroke of the electric push rod responsible for rotating and horizontally extending the shower arm 15 is 100mm, the electric push rod is powered by a 24V DC power supply, the speed is 100mm / s, the self-weight is 1-2kg, the push / pull force can reach 2000 / 1300N·m, and the IP63-IP64 waterproof standard is provided, the working decibel produces white noise lower than 40DB.
