DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

[0024] Referring to Figures 1 to 8 As shown in the figure: a kind of auxiliary marking device for cosmetic injection, including main ruler 1, the middle part of main ruler 1 is provided with holding plate 2, control switch 21 is provided on holding plate 2, the lower end of main ruler 1 is provided with auxiliary marking structure 3 and locking mechanism 4;Auxiliary marking structure 3 includes hoisting plate 31 and several marking units 32, hoisting plate 31 is arranged in parallel below main ruler 1, the two ends of hoisting plate 31 are connected with the two ends of main ruler 1 respectively, several marking units 32 are arranged at equal intervals on hoisting plate 31, and marking unit 32 is slidably connected with hoisting plate 31;Locking mechanism 4 is arranged at the upper end of hoisting plate 31, locking mechanism 4 includes two clamping structures 41 and drive structure 42, two clamping structures 41 are arranged at the two sides of marking unit 32 respectively, clamping structure 41 includes clamping plate 411 and thrust plate 412, the side of clamping plate 411 away from marking unit 32 is provided with first slope 4111, thrust plate 412 is fixed on hoisting plate 31, the side of thrust plate 412 towards clamping plate 411 is provided with second slope 4121, first slope 4111 and second slope 4121 have the same inclination angle, and they are mutually adhered, drive structure 42 is arranged at the same end of two clamping structures 41, and drive structure 42 is connected with two clamping plates 411 in two clamping structures 41.

[0025] When the device is used, first, the main ruler 1 is placed horizontally above the face of the operator, at this time, a plurality of marking units 32 below the lifting plate 31 remain the same height due to the action of gravity, that is, the distance between the lowest point of each marking unit 32 and the lifting plate 31 is consistent, then, the main ruler 1 moves stably to the face of the operator until each marking unit 32 contacts the face of the operator, due to the unevenness of the contour of the face of the operator, each marking unit 32 is subjected to different forces, resulting in a difference in the distance that each marking unit 32 moves in the direction of the main ruler 1, once the marking unit 32 is attached to the face of the operator, the control switch 21 is pressed, the driving structure 42 is started, the driving structure 42 immediately pushes the two clamping structures 41 to move along the arrangement direction of the marking unit 32, in the moving process, the first slope 4111 on the clamping plate 411 interacts with the second slope 4121 on the thrust plate 412, since the thrust plate 412 is fixed, the clamping plate 411 gradually moves away from the thrust plate 412 under the guidance of the first slope 4111 and the second slope 4121, the two clamping plates 411 clamp each marking unit 32 from both sides, which ensures that the distance between all marking units 32 and the main ruler 1 is fixed, forming a stable contour mark, finally, the face is marked along the marking unit 32, providing accurate guidance for subsequent cosmetic injection, by slidingly connecting a plurality of marking units 32 on the lifting plate 31, the marking unit 32 does not exert force on the face of the operator during movement, avoiding deformation of the face of the operator, the driving structure 42 fixes a plurality of marking units 32, avoiding movement of the marking unit 32 when marking the face of the operator, thereby effectively preventing deformation of the face of the operator during marking, further improving the accuracy of marking.

[0026] Referring to Figure 3 and Figure 4 It is shown that: the marking unit 32 comprises a U-shaped marking plate 321, a guide rod 322 and a limiting hanging block 323; the U-shaped marking plate 321 is arranged at the lower end of the lifting plate 31; one end of the guide rod 322 is connected to the middle part of the U-shaped marking plate 321, the other end of the guide rod 322 passes through the lifting plate 31 upwardly and is slidingly connected with the lifting plate 31, two clamping planes 3221 are formed on the guide rod 322, the clamping planes 3221 extend from one end of the guide rod 322 to the other end, and the clamping planes 3221 are parallel to the clamping plate 411; the limiting hanging block 323 is arranged at the upper end of the lifting plate 31, and the limiting hanging block 323 is connected with the guide rod 322.

[0027] In the initial state, the limiting hanging block 323 is in contact with the hoisting plate 31, effectively preventing the U-shaped marking plate 321 from falling off the hoisting plate 31. When the device is used for the face of the surgeon, the lower end of the U-shaped marking plate 321 first contacts the face. Due to the unevenness of the face contour, each U-shaped marking plate 321 will stop at different positions due to the different contact points below, and thus the one end of the guide rod 322 will be exposed to different lengths on the upper end of the hoisting plate 31. Although the stop positions of each marking unit 32 are different, the clamping plane 3221 on the guide rod 322 always exists, providing a reliable contact surface for subsequent clamping operations. When the driving structure 42 starts and pushes the clamping plate 411 to move along the arrangement direction of the marking unit 32, the clamping plate 411 can contact the clamping plane 3221 of the guide rod 322 in each marking unit 32, thereby achieving simultaneous clamping and fixing of several different state marking units 32.

[0028] Referring to Figure 5 and Figure 6 As shown: the clamping structure 41 further comprises a rubber pad 413, which is arranged on the side of the clamping plate 411 facing the guide rod 322, and the rubber pad 413 completely covers the clamping plate 411.

[0029] When the clamping plate 411 is tightly attached to the clamping plane 3221 of the guide rod 322 under the push of the driving structure 42, achieving fixation of the guide rod 322, the marking unit 32 needs to be tightly attached to the face contour of the surgeon. At this time, the marking unit 32 will continuously be subjected to a force in the direction of the guide rod 322, which is derived from the reaction force of the face of the surgeon. If only relying on the direct friction between the clamping plate 411 and the guide rod 322, when the force exceeds the static friction between the clamping plate 411 and the guide rod 322, relative sliding between the guide rod 322 and the clamping plate 411 may occur, thereby affecting the accuracy of the marking. By adding a rubber pad 413 to the clamping plate 411 and making it fully cover, the rubber pad 413 can significantly increase the static friction between the guide rod 322 and the clamping plate 411, effectively improving the ability of the clamping structure 41 to resist external forces, thereby effectively preventing relative sliding caused by external forces and enhancing the stability and reliability of the clamping structure 41.

[0030] Referring to Figure 6 As shown: the first slope 4111 has a plurality of first slopes 4111 arranged at equal intervals on the clamping plate 411, and the second slope 4121 has a plurality of second slopes 4121 arranged at equal intervals on the thrust plate 412. The plurality of first slopes 4111 and the plurality of second slopes 4121 correspond to each other and are in close contact.

[0031] The number of marking units 32 is large, and therefore the length of the clamping plate 411 is long. Only by matching the first slope 4111 and the second slope 4121, the force of the clamping plate 411 towards the marking units 32 is exerted. The force of the clamping plate 411 on the guide rod 322 in different marking units 32 is different. By arranging a plurality of first slopes 4111 and second slopes 4121, when the clamping plate 411 moves, a plurality of first slopes 4111 slide along a plurality of second slopes 4121 respectively, and a plurality of second slopes 4121 can exert force on the clamping plate 411 through a plurality of first slopes 4111, so that the clamping plate 411 receives a plurality of equal-interval and same-size forces, thereby realizing that the clamping force of the clamping plate 411 on a plurality of marking units 32 is the same.

[0032] Referring to Figure 4 and Figure 7 The driving structure 42 includes a driving plate 421, two connecting shafts 422 and a linear driver 423. The driving plate 421 is perpendicular to the two clamping plates 411, and two ends of the driving plate 421 are provided with strip-shaped sliding grooves 4211. The two connecting shafts 422 are respectively connected with the ends of the two clamping plates 411, and the two connecting shafts 422 are respectively slidably arranged in the two strip-shaped sliding grooves 4211.

[0033] When a plurality of marking units 32 are attached to the face of the operator, the linear driver 423 works, and the linear driver 423 drives the driving plate 421 to move towards the end of the hoisting plate 31. The two slot walls of the two strip-shaped sliding grooves 4211 on the driving plate 421 respectively exert force on the two connecting shafts 422, so that the two connecting shafts 422 drive the two clamping plates 411 to move towards the end of the hoisting plate 31. The two clamping plates 411 also move closer to each other during the movement. At this time, the two connecting shafts 422 move along the two strip-shaped sliding grooves 4211 respectively, and the two strip-shaped sliding grooves 4211 continuously exert force on the connecting shafts 422, thereby realizing the clamping of the two clamping structures 41 on a plurality of marking units 32.

[0034] Referring to Figure 4 and Figure 8As shown: the locking mechanism 4 further comprises a limiting guide structure 43, the limiting guide structure 43 is arranged at the same end of the two clamping structures 41, the limiting guide structure 43 comprises a fixed seat 431, a guide crossbar 432, two sliding blocks 433, two telescopic arms 434 and two springs 435; the fixed seat 431 is arranged between the two clamping plates 411; the two ends of the guide crossbar 432 are perpendicular to the plane where the two clamping plates 411 are located respectively, and the middle part of the guide crossbar 432 is connected with the fixed seat 431; the two sliding blocks 433 are slidingly arranged at the two ends of the guide crossbar 432 respectively; the two telescopic arms 434 correspond to the two sliding blocks 433 respectively, and the two ends of the telescopic arm 434 are connected with the clamping plate 411 and the sliding block 433 respectively; the two springs 435 are sleeved on the guide crossbar 432, and the two ends of the spring 435 are abutted with the sliding block 433 and the fixed seat 431 respectively.

[0035] When the driving structure 42 drives the two clamping plates 411 to move close to each other, the clamping plate 411 drives the sliding block 433 to move along the guide crossbar 432 towards the fixed seat 431 through the transmission action of the telescopic arm 434, in the process, the spring 435 is gradually compressed to store elastic potential energy, at the same time, since the clamping plate 411 will also generate a movement trend away from the guide crossbar 432 in the process of moving close to each other, the telescopic arm 434 is therefore lengthened, ensuring that the clamping plate 411 and the sliding block 433 always maintain stable connection, when the driving structure 42 drives the two clamping plates 411 to move away from each other, the two compressed springs 435 begin to release the stored elastic potential energy, and push the sliding block 433 to move in the opposite direction along the guide crossbar 432, the sliding block 433 makes the two ends of the clamping plate 411 receive the force of moving away from each other through the transmission action of the telescopic arm 434, so as to realize the stable separation of the clamping plate 411.

[0036] The above embodiment only expresses one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
