DETAILED DESCRIPTION

[0022] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] A product fastening and pressure-maintaining fixture, such as Figures 1-4 As shown, it includes an upper carrier 1, a lower carrier 2 and an unlocking fixture 3. A work station 21 for placing products is provided on the top of the lower carrier 2. A pressing part 11 that can be extended into the work station 21 to press the products is fixedly connected to the middle of the bottom of the upper carrier 1. The upper carrier 1 is provided with several locking structures for limiting the upper carrier 1 from being away from the lower carrier 2.

[0024] The four corners of the upper carrier 1 are provided with through holes, and the through holes are fixedly connected to the limiting sleeves. The positioning rod 4 is inserted into the limiting sleeve and slidably connected to the inner wall of the limiting sleeve. The top ends of the two positioning rods 4 on the same side of the pressing portion 11 pass through the upper carrier 1 and are connected by a connecting piece 42. The setting of the connecting piece 42 limits the rotational freedom of the positioning rod 4 and ensures the stability of the movement of the positioning rod 4; a return spring 43 is sleeved on the top end of the positioning rod 4, one end of the return spring 43 abuts against the bottom of the connecting piece 42, and the other end of the return spring 43 abuts against the top of the upper carrier 1; the positioning rod 4 is reset by setting the return spring 43;

[0025] The bottom end of the positioning rod 4 is provided with a receiving groove 41, the number of the clips 411 in the receiving groove 41 is set to two and they are arranged symmetrically with the center, and are rotatably connected to the inner side wall of the receiving groove 41 through the same rotating shaft, and the two clips 411 are integrally formed with a guide portion extending toward the outside of the positioning rod 4 on one side away from each other, and one side of the guide portion is tilted downward, and a torsion spring 412 is provided in the receiving groove 41, and the two ends of the torsion spring 412 extend toward the two clips 411 respectively and extend with the side close to each other of the two clips 411. The two ends of the torsion spring 412 are respectively fitted with the two side walls of the accommodating groove 41. The torsion spring 412 has good elasticity. The torsion spring 412 is used to rotate the two buckles 411 in the direction away from each other, so that the guide portion extends out of the accommodating groove 41. A limiting rod 413 is provided in the accommodating groove 41, and an arc groove for the limiting rod 413 to pass through is provided on the buckle 411. By setting the limiting rod 413 and the arc groove, the rotation angle of the buckle 411 is limited, so that the rotation of the buckle 411 is more stable.

[0026] The top of the lower tool 2 is located around the work station 21 and corresponds to the locking structure one by one. A positioning hole 221 is provided on the top of the limiting part 22 and passes through it. A groove 222 is integrally formed on one side of the limiting part 22 and is connected to the positioning hole 221. A fixing block 223 is fixedly connected to the bottom wall of the groove 222. A limiting hole is provided on the fixing block 223. The limiting hole is chamfered toward the opening of the positioning hole 221 to form a guide surface. The setting of the guide surface has a good guiding effect, making it more convenient and quick for the buckle 411 to pass through the limiting hole. The aperture of the limiting hole is smaller than the aperture of the positioning hole 221, and the aperture of the limiting hole is smaller than the horizontal maximum distance between the two buckles 411 on the same positioning rod 4, thereby completing the restriction of the buckle 411 through the limiting hole, preventing the positioning rod 4 from disengaging from the limiting part 22, and thus preventing the upper carrier 1 from disengaging from the lower tool 2.

[0027] The top of the unlocking jig 3 is provided with four unlocking sleeves 31 corresponding to the limit members 22 one by one. The four unlocking sleeves 31 can be inserted into the groove 222 from the bottom of the limit member 22. An unlocking hole for the positioning column to pass through is provided on the unlocking sleeve 31. The unlocking hole is connected to the limit hole, and the aperture of the unlocking hole is equal to the aperture of the limit hole. A sliding cavity 32 is provided on the top of the unlocking jig 3. The unlocking sleeve 31 is inserted into the sliding cavity 32 and slides with the inner wall of the sliding cavity 32. The sliding connection of the unlocking sleeve 31 can adapt to products of different thicknesses and upper and lower carriers 1 and 2 of different specifications, thereby ensuring the adaptation effect of the explanation jig. By setting the sliding cavity 32, the moving trajectory of the unlocking sleeve 31 is limited, making the movement of the unlocking sleeve 31 more stable; an unlocking spring 321 is provided in the sliding cavity 32, and the elasticity of the unlocking spring 321 is utilized to make the unlocking sleeve 31 continuously extend out of the sliding cavity 32, which has a good lifting effect, thereby ensuring the interpretation effect of the unlocking sleeve 31, and also has a good buffering effect, ensuring the service life of the unlocking sleeve 31; four positioning blocks 33 are fixedly connected to the top of the unlocking jig 3, and the cross-section of the positioning blocks 33 are all L-shaped, and the positioning blocks 33 cover the four corners of the lower jig 2, thereby having a good positioning effect.

[0028] Working principle: put the product back shell into the work station 21, and cover the product cover on the top of the product back shell, then press down the upper carrier 1, cover the upper carrier 1 on the top of the lower carrier 2, so that the pressing part 11 extends into the work station 21, and completes the product pressing. At this time, the positioning rod 4 is inserted into the positioning hole 221, and the opening of the upper limit hole of the fixing block 223 first touches the guide part of the buckle 411. Through the guiding effect, the two buckles 411 located in the same positioning rod 4 are close to each other until the guide part retracts into the receiving groove 41, and the torsion spring 412 is deformed by the external force. At this time, the positioning rod 4 can easily pass through the fixing block 223. At the same time, due to the influence of the product thickness, the upper carrier 1 cannot continue to descend, and it is necessary to press the connecting piece 42 to compress the return spring 43 so that the buckle 411 can completely pass through the fixing block 223.

[0029] When it has completely passed, the torsion spring 412 is not affected by external forces, and its own elasticity causes the guide portion of the buckle 411 to extend out of the receiving groove 41, and the top of the guide portion contacts the bottom of the fixing block 223. In addition, the return spring 43 also uses its own elasticity to make the positioning rod 4 have an upward force, and the top surface of the guide portion of the buckle 411 presses the bottom of the fixing block 223, thereby ensuring the fixing effect of the upper carrier 1 and the lower carrier 2 as a whole, and further ensuring the pressure maintenance effect between the upper carrier 1 and the lower carrier 2.

[0030] When the upper carrier 1 and the lower carrier 2 are fixed together and placed between the four positioning blocks 33 on the unlocking fixture 3, and embedded in the four positioning grooves, the unlocking sleeve 31 is inserted into the limit piece 22, and the positioning rod 4 is also inserted into the unlocking sleeve 31. The guide part of the buckle 411 first touches the unlocking sleeve 31. Through the guiding effect, the two buckles 411 located in the same positioning rod 4 are close to each other. When the top of the unlocking sleeve 31 contacts the bottom of the fixed block 223, the buckle 411 is retracted into the unlocking sleeve 31. Since the aperture of the unlocking hole is equal to the aperture of the limiting hole, the elasticity of the return spring 43 causes the positioning rod 4 to move upward until the buckle 411 extends into the limiting hole of the fixed block 223 or moves upward to separate from the fixed block 223. At this time, the upper carrier 1 and the lower carrier 2 can be quickly separated, and the unlocking is completed, which is faster and faster.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
