DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 , Figure 2As shown, the utility model provides a plate-type evaporator which is easy to disassemble and assemble, including a fixed pressing plate 1, a connecting and fixing mechanism 3 is arranged on the left and right sides of the fixed pressing plate 1, a heating plate 4 is arranged on the rear side of the fixed pressing plate 1, and a movable pressing plate 2 is arranged on the rear side of the heating plate 4, three movable grooves 11 are opened on the left and right sides of the fixed pressing plate 1, and movable holes 12 are opened on the upper and lower sides of the inner parts of the three movable grooves 11, the connecting and fixing mechanism 3 includes three fastening connecting rods 31, connecting rods 32 are fixedly connected between the outer walls of the three fastening connecting rods 31, rotating rods 33 are fixedly installed on the upper and lower sides of the outer walls of the three fastening connecting rods 31, and two rotating rods 33 on the upper and lower sides of the outer walls of the three fastening connecting rods 31 are respectively movably connected with the two movable holes 12 on the upper and lower sides of the inner parts of the three movable grooves 11, and three clamping grooves 21 are opened on the left and right sides of the movable pressing plate 2, and the three clamping grooves 21 opened on the left and right sides of the movable pressing plate 2 are respectively on the same horizontal line as the three movable grooves 11 opened on the left and right sides of the fixed pressing plate 1;

[0021] When installing the plate-type evaporator, align the fixed pressing plate 1, the heating plate 4, and the movable pressing plate 2, and then rotate the fastening connecting rods 31 in the three movable grooves 11 on the left and right sides of the fixed pressing plate 1 by rotating the rotating rod 33 in the movable hole 12, so that the three fastening connecting rods 31 on the left and right sides of the fixed pressing plate 1 are all rotated and clamped into the three clamping grooves 21 on the left and right sides of the movable pressing plate 2 by the connected connecting rods 32, and the three fastening connecting rods 31 on both sides of the fixed pressing plate 1 can be quickly rotated, installed and disassembled by using the connecting rods 32.

[0022] like Figure 3 , Figure 4As shown, a driving groove 311 is provided at the center of the rear end of the three fastening connecting rods 31, and a through rotation hole 313 is provided on the front side of the inner wall of the three driving grooves 311, which penetrates to the front end of the fastening connecting rod 31, and a limiting sliding groove 312 is provided on the side of the fastening connecting rod 31 away from the fixed pressing plate 1, and an adjusting rotating rod 314 is movably installed on the inner circle of the through rotation hole 313, and the front end of the adjusting rotating rod 314 penetrates to the front side of the fastening connecting rod 31 and is fixedly installed with an adjusting knob 315, and the rear end of the adjusting rotating rod 314 penetrates to the inner cavity of the driving groove 311 and is fixedly installed with a threaded rod 316, and a tightening mechanism 317 is threadedly installed on the outer wall of the threaded rod 316, and the rear end of the threaded rod 316 is fixedly installed with The limiting block prevents the tightening mechanism 317 from falling off. The tightening mechanism 317 includes a moving ring 3171, which is threadedly connected to the outer wall of the tightening mechanism 317. A connecting slider 3172 is fixedly installed on the side of the moving ring 3171 close to the limiting slide groove 312. The connecting slider 3172 is slidably connected to the connecting slider 3172. A tightening ring 3173 is fixedly installed on the end of the connecting slider 3172 away from the moving ring 3171. The inner ring of the tightening ring 3173 overlaps the outer wall of the fastening connecting rod 31. A rubber ring 3174 is fixedly installed on the front side of the tightening ring 3173. The rubber ring 3174 can increase the friction between the tightening ring 3173 and the outer wall of the rear side of the movable pressing plate 2 when tightening, thereby making its fixation more stable.

[0023] By rotating the adjusting knobs 315 at the front ends of the three fastening connecting rods 31 on the left and right sides of the fixed clamping plate 1, the adjusting rotating rod 314 and the threaded rod 316 are driven to rotate, so that the movable ring 3171 on the outer wall of the threaded rod 316 slides in the limiting sliding groove 312 by means of the connecting slider 3172, thereby stably driving the tightening ring 3173 to move forward, and the diameter of the tightening ring 3173 is higher than the height of the clamping groove 21, so the tightening ring 3173 will use the rubber ring 3174 to stop against the rear side of the movable clamping plate 2, thereby completing the rapid clamping and fixing of the fixed clamping plate 1 and the movable clamping plate 2. When disassembling, the adjusting knob 315 can be directly reversed to reverse the threaded rod 316, so that the movable ring 3171 drives the tightening ring 3173 to move backward, and after releasing the clamping state of the fixed clamping plate 1 and the movable clamping plate 2, the fastening connecting rod 31 can be rotated outward and pulled out.

[0024] like Figure 5As shown, the three fastening connecting rods 31 are respectively engaged with the three engaging grooves 21, and the tightening mechanism 317 after engaging is located at the rear side of the movable pressing plate 2. The bottoms of the three engaging grooves 21 on the left and right sides of the movable pressing plate 2 are provided with positioning grooves 211, and positioning boxes 212 are fixedly installed inside the three positioning grooves 211. The bottoms of the inner walls of the three positioning boxes 212 are fixedly installed with compression springs 213, and the tops of the three compression springs 213 are fixedly installed with limit block bottom plates 214. The four side surfaces of the limit block bottom plates 214 are overlapped with the four side surfaces of the inner wall of the positioning box 212 respectively, and the tops of the three limit block bottom plates 214 are fixedly installed with trapezoidal limit blocks 215, and the tops of the three trapezoidal limit blocks 215 respectively penetrate to the bottoms of the three engaging grooves 21.

[0025] When the fastening connecting rod 31 is inserted into the snap-in groove 21, the trapezoidal limit block 215 on the top of the positioning box 212 in the positioning groove 211 will be squeezed. The trapezoidal limit block 215 will be squeezed downward by using the inclined surface on one side of the trapezoidal limit block 215, thereby cooperating with the limit block bottom plate 214 to squeeze the compression spring 213. When the fastening connecting rod 31 is completely inserted into the snap-in groove 21, the trapezoidal limit block 215 can pop up again under the rebound of the compression spring 213, and limit the fastening connecting rod 31, thereby facilitating the next step of reinforcement to prevent it from falling off the snap-in groove 21. When disassembling, it can be directly squeezed through the inclined surface on the other side of the trapezoidal limit block 215 and then detached from the snap-in groove 21.

[0026] The following is a detailed description of the working principle of the plate evaporator which is easy to disassemble and assemble.

[0027] like Figure 1-5When the locking cam 31 is in the state of being moved, the locking cam 31 is in the state of being moved, and the locking cam 31 is in the state of being moved. The adjusting knobs 315 at the front ends of the three fastening connecting rods 31 on the left and right sides of the clamping plate 1 can then be rotated to fix the clamping plate 1, thereby driving the adjusting rotating rod 314 and the threaded rod 316 to rotate, so that the moving ring 3171 on the outer wall of the threaded rod 316 can slide in the limiting sliding groove 312 by means of the connecting slider 3172, thereby stably driving the tightening ring 3173 to move forward, and the diameter of the tightening ring 3173 is higher than the height of the clamping groove 21, so the tightening ring 3173 can be used to tighten the clamping ring 3173. The rubber ring 3174 stops against the rear side of the movable clamping plate 2, thereby completing the quick clamping and fixing of the fixed clamping plate 1 and the movable clamping plate 2. When disassembling, directly reverse the adjusting knob 315 to reverse the threaded rod 316, so that the movable ring 3171 drives the tightening ring 3173 to move backward, and then release the clamping state of the fixed clamping plate 1 and the movable clamping plate 2. Then, rotate the fastening connecting rod 31 outward and pull it out, and directly squeeze through the trapezoidal limit block 215 to disengage from the snap-in groove 21.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
