[0065] The base 20 is arranged on the substrate 10, and the base is used to support the product part (not shown). Through the first pressing member 50 and the first locking member 60, the first target body (not shown) can be kept under pressure at the top preset position of the product part, and then the second pressing member 70 and the second locking member 80 can be used to keep the second target body (not shown) under pressure at the side preset position of the product part, thereby achieving the fixation of the product part from two directions.

In other embodiments, the first target body and the second target body can be other parts.

[0066] The first pressure cover 30 is detachably connected to the substrate 10. After the product is mounted on the base 20, the first pressure cover 30 is placed on the side of the product away from the substrate 10. Figure 1As shown, the first pressure cover 30 and the substrate 10 are respectively located on the upper and lower sides of the base 20 , and the first pressure cover 30 is located at the top of the base 20 .

[0067] The first pressing member 50 is arranged on the first pressure cover 30. The first pressing member 50 includes at least one. The shape and position of the first pressing member 50 can be set according to the shape and position of the first target member. Multiple first pressing members 50 are pressed against the first target body together to maintain pressure on the first target body to improve the connection strength.

[0068] The first locking member 60 has a first locking posture and a first unlocking posture. When the first locking member 60 is in the first locking posture, the first pressure cover 30 is locked to the substrate 10 through the first locking member 60, so that the first pressure cover 30 and the substrate 10 form a whole, and the first target body is maintained on the product part; when the first locking member 60 is in the first unlocking posture, the first pressure cover 30 is separated from the substrate 10, and the first target body can be assembled to the product part.

[0069] Reference Figure 2 As shown, the second pressure cover 40 is spaced apart on one side of the base 20, and the second pressure cover 40 is detachably connected to the substrate 10 and / or the first pressure cover 30. After the first pressure cover 30 forms a whole with the substrate 10 through the first locking member 60, the second pressure cover 40 is connected to the substrate 10 or the first pressure cover 30, so that the second pressure cover 40 keeps the second target body pressed on the product part.

[0070] The second pressing member 70 is provided on the second pressure cover 40. The second pressing member 70 includes at least one. The shape and position of the second pressing member 70 can be determined according to the shape and position of the second target body. Multiple second pressing members 70 are pressed together on the second target body to maintain pressure on the second target body to improve the connection strength.

[0071] The second locking member 80 has a second locking posture and a second unlocking posture. When the second locking member 80 is in the second locking posture, the second pressure cover 40 is locked with the substrate 10 and / or the first pressure cover 30 to form a whole, so as to maintain the pressure of the second target body on the product part; when the second locking member 80 is in the second unlocking posture, the second pressure cover 40 is separated from the substrate 10 and / or the first pressure cover 30, and the second target body can be assembled to the product part.

[0072] The working principle of the composite pressure-maintaining integrated fixture 100 of the present invention is as follows:

[0073] Firstly, the product is placed on the base 20, at this time the first locking member 60 is in the first unlocking posture, the first target body is assembled on the product, and then the first cover 30 is covered, then the first locking member 60 is adjusted to the first locking posture, so that the first cover 30 is locked with the base plate 10 to form an integral whole, and the first pressing member 50 on the first cover 30 presses the first target body on the top end of the product.

[0074] The composite holding jig 100 is rotated by 90 degrees, at this time the second locking member 80 is in the second unlocking posture, the first target body is assembled on the product, and then the second cover 40 is covered, then the second locking member 80 is adjusted to the second locking posture, so that the second cover 40 forms an integral whole with the base plate 10 and / or the first cover 30, and the second pressing member 70 on the second cover 40 presses the second target body on the side end of the product, thereby realizing the assembly and holding of the product in multiple directions by using a set of jigs.

[0075] In the embodiments provided in the present application, referring to Figures 3 to 5 As shown in the figure, the plurality of first pressing members 50 each include a mounting block 51, a first pressing block 52, a first elastic member 53, a connecting rod 54 and a limiting block 55, the mounting block 51 is arranged on the first cover 30, a guide hole 511 is formed through the mounting block 51, the first pressing block 52 is used to press on the first target body, the two ends of the first elastic member 53 are connected with the first pressing block 52 and the mounting block 51 respectively, when the first pressing block 52 presses on the first target body, the force of the first target body on the first pressing block 52 makes the first pressing block 52 move towards the mounting block 51, in the moving process of the first pressing block 52, the first elastic member 53 is elastically deformed to accumulate elastic force, the elastic force acts on the first pressing block 52, so that the first pressing block 52 can firmly press on the first target body to continuously exert force; when the first pressing block 52 is separated from the first target body, under the action of the gravity of the first pressing block 52 and the elastic force accumulated by the first elastic member 53, the first pressing block 52 moves away from the mounting block 51 until the first elastic member 53 returns to the natural elongation state, so that the first pressing block 52 can elastically move back and forth.

[0076] One end of the connecting rod 54 is connected to the first pressure block 52, and the other end of the connecting rod 54 extends through the guide hole 511 and is connected to the limit block 55. During the elastic reciprocating process of the first pressure block 52, the connecting rod 54 can move back and forth along the guide hole 511 as the first pressure block 52 moves, thereby driving the limit block 55 to move back and forth. The limit block 55 is arranged on the side of the mounting block 51 away from the first pressure block 52. When the first pressure block 52 is separated from the first target body and the first pressure block 52 moves in the direction away from the mounting block 51, in order to prevent the first pressure block 52 from falling out, the limit block 55 abuts against the top of the mounting block 51 to limit the first pressure block 52 from continuing to move.

[0077] In a feasible embodiment, referring to Figure 3 as well as Figure 4 As shown, the shape of the ends of the multiple first pressing blocks 52 is adapted to the shape of the first target body, so that the surface of each first pressing block 52 can be tightly pressed against the corresponding position of the first target body, thereby achieving stable pressure on the first target body by the multiple first pressing members 50.

[0078] Reference Figure 1 As shown in Figure 6, the first locking member 60 includes a plurality of first locking blocks 61 and a plurality of first locking matching blocks 62, and the plurality of first locking blocks 61 correspond one to one with the plurality of first locking matching blocks 62. In the embodiment provided by the present application, the first locking matching block 62 is connected to the first pressure cover 30, and the first locking block 61 is connected to the substrate 10. The first locking block 61 can move along a first preset path, which is a movement path for the first locking member 60 to change from the first unlocking posture to the first locking posture. When the first locking member 60 is in the first unlocking posture, the first locking block 61 and the first locking matching block 62 are unlocked. At this time, the first locking block 61 is located at the starting end of the first preset path, the first pressure cover 30 and the substrate 10 can be separated, and the first pressing member 50 is not pressed against the first target body.

[0079] When the first locking member 60 is in the first locking posture, a locking fit is formed between the first locking block 61 and the first locking matching block 62. At this time, the first locking member 60 is located at the end of the first preset path, the first pressure cover 30 and the substrate 10 are locked to form a whole, and multiple first pressing members 50 are respectively pressed on the first target body, and the product part can be fixed in the base 20 at the same time.

[0080] In a feasible embodiment, referring to Figure 6 as well as Figure 7As shown, a plurality of pivot seats 63 are provided on the substrate 10, and the plurality of pivot seats 63 correspond one-to-one to the plurality of first locking blocks 61. The first locking block 61 is pivotally connected to the pivot seat 63. The first preset path is the rotational movement path of the first locking block 61 with the pivot axis of the pivot seat 63 as the center. The first locking block 61 is an inverted L-shaped plate body. One end of the first locking block 61 is pivotally connected to the pivot seat 63, so that the first locking block 61 can rotate with the pivot axis of the pivot seat 63 as the center. The other end of the first locking block 61 is formed with a first upper locking surface 611, and the top of the pivot seat 63 is formed with a first lower locking surface 631.

[0081] Reference Figure 8 as well as Figure 9 As shown, the first locking mating block 62 is in an inverted L-shape, a first upper locking mating surface 621 is formed at the top end of the first locking mating block 62, a first lower locking mating surface 622 is formed at the bottom end of the first locking mating block 62, and a locking mating groove 623 is formed at the side end of the first locking mating block 62, and the shape of the locking mating groove 623 is adapted to the shape of the side end of the first locking block 61.

[0082] When the first pressure cover 30 is connected to the substrate 10, the first lower locking mating surface 622 is supported on the first lower locking surface 631, so that the first locking mating block 62 is supported on the top of the pivot seat 63, and the first locking block 61 is moved to the end of the first preset path, so that the first upper locking surface 611 is pressed against the first upper locking mating surface 621. At the same time, the side end of the first locking block 61 extends into the locking mating groove 623, forming a clearance fit with the locking mating groove 623. At this time, the first locking member 60 is in the first locking posture, thereby completing the assembly of the first pressure cover 30 and the substrate 10.

[0083] , refer to Figure 1 As shown, the pivot seat 63, the first locking block 61 and the first locking matching block 62 each include four, the four pivot seats 63 are evenly distributed along the edge of the substrate 10, the four first locking blocks 61 are pivotally connected to a pivot seat 63 respectively, the four first locking matching blocks 62 are evenly distributed along the edge of the first substrate 10 and extend downward, each first locking matching block 62 corresponds to a pivot seat 63, when connecting the first pressure cover 30 with the substrate 10, first the first lower locking matching surfaces 622 at the bottom ends of the four first locking matching blocks 62 are pressed against the first lower locking surfaces 631 of the corresponding pivot seats 63, so that the first pressure cover 30 is supported above the substrate 10, and then the four first locking blocks 61 are moved to the first upper locking surface 611 to abut against the corresponding first upper locking matching surface 621, and the side end of each first locking block 61 extends into the corresponding locking matching groove 623, thereby completing the locking of the first pressure cover 30 with the substrate 10.

[0084] In order to improve the stability and reliability of the locking of the first grommet 30 and the substrate 10, in the embodiments provided by the present application, referring to Figures 6 to 9 As shown in the figure, the first locking member 60 further comprises a limiting baffle 64, which is directly arranged on the substrate 10 or connected to the substrate 10 through a connecting member. The limiting baffle 64 comprises a first side plate 641 and a second side plate 642, which are connected to form an L-shaped baffle. When the first lower locking matching surface 622 is pressed against the first lower locking surface 631, the first side plate 641 and the second side plate 642 abut against the side ends of the first locking matching block 62 respectively to position the first locking matching block 62, so that the first locking block 61 can accurately lock the first grommet 30 and the substrate 10.

[0085] In the process of moving of the plurality of first locking blocks 61 along the first preset path, in order to improve the stability and convenience of the simultaneous movement of the plurality of first locking blocks 61, the plurality of first locking blocks 61 are symmetrically arranged on opposite sides of the base 20, and at least two adjacent first locking blocks 61 on the same side are connected through a handle 65. In the embodiments provided by the present application, referring to Figure 6 As shown in the figure, the composite pressure maintaining integrated jig 100 is provided with two handles 65, which are symmetrically arranged on opposite sides of the base 20. Four first locking blocks 61 are symmetrically arranged on opposite sides of the base 20. The two ends of one handle 65 are respectively connected to the top ends of two first locking blocks 61 on the same side, and the two handles 65 respectively connect two adjacent first locking blocks 61 on the same side. When locking the first grommet 30 and the substrate 10, after pressing the first locking matching block 62 against the pivot seat 63, the operator holds the handle 65 and simultaneously rotates the two first locking blocks 61 on the same side to the end of the first preset path through the handle 65, so that the first upper locking surface 611 abuts against the first upper locking matching surface 621, to complete the locking of the first grommet 30 and the substrate 10.

[0086] After locking the first grommet 30 and the substrate 10 by using the first locking member 60 and the plurality of first pressing members 50, the second grommet 40 is locked with the substrate 10 and / or the first grommet 30 by using the second locking member 80 and the plurality of second pressing members 70. In the embodiments provided by the present application, the second locking member 80 comprises two, which are symmetrically arranged on opposite sides of the second grommet 40, so as to facilitate the locking or separation of the second grommet 40 with the substrate 10 and the first grommet 30 respectively. The second pressing member 70 comprises two, which are symmetrically arranged on the side ends of the product member.

[0087] Referring to Figures 10 to 12As shown, the second pressing member 70 includes a plurality of pressing blocks 71 and a plurality of second elastic members 72. The plurality of pressing blocks 71 are arranged in a ring-shaped manner with a preset axis as the center line. The pressing blocks 71 are adapted to the surface shape of the second target body that is pressed against, so that the second pressing member 70 can be tightly pressed against the second target body.

[0088] The plurality of pressing blocks 71 are connected to the plurality of second elastic members 72 in a one-to-one correspondence. One end of each second elastic member 72 is connected to the second gland 40, and the other end of the second elastic member 72 is connected to the corresponding pressing block 71. When the second gland 40 is placed on the side end of the product, the plurality of pressing blocks 71 are pressed against the second target body. The force of the second target body on each pressing block 71 causes the plurality of pressing blocks 71 to move in the direction close to the second gland 40, thereby causing the corresponding second elastic member 72 to undergo elastic deformation and accumulate. The elastic force is stored and acts on the corresponding pressing block 71, so that the second pressing member 70 can maintain the state of being in contact with the second target body; when the locking state of the second pressure cover 40 and the substrate 10 and / or the first pressure cover 30 is released, the second pressing member 70 is separated from the side end of the product part, and the state of each pressing block 71 being in contact with the second target body is released. The elastic force accumulated by the second elastic member 72 pushes the corresponding pressing block 71 to move away from the second pressure cover 40 until the second elastic member 72 returns to a naturally extended state.

[0089] In a feasible embodiment, the pressing blocks 71 include four, corresponding to which are provided four second elastic members 72. The four pressing blocks 71 are arranged in a ring-shaped interval. When the four second elastic members 72 are in a naturally extended state, the surfaces of the four pressing blocks 71 can form a smoothly connected arc surface. When the four pressing blocks 71 are respectively pressed against the second target body, each pressing block 71 can be elastically reciprocated independently under the action of the corresponding second elastic member 72 according to the state of pressing against the second target body.

[0090] Reference Figures 13 to 15As shown, the second locking member 80 includes a second locking block 81 and a second locking matching block 82. The second locking block 81 is arranged on the substrate 10 and / or the first pressure cover 30, and the second locking matching block 82 is arranged on the second pressure cover 40. The second locking matching block 82 can move along a second preset path. The second preset path is a linear route for the second locking matching block 82 to approach or move away from the second locking block 81. The starting end of the second preset path is the position where the second locking matching block 82 is away from the second locking block 81. When the second locking matching block 82 is at the starting end of the second preset path, the second locking member 80 is in a second unlocking posture, and the second pressure cover 40 can be separated from the substrate 10 and / or the first pressure cover 30. At this time, the second target body can be assembled to the product part, or the second pressure cover 40 can be evacuated after maintaining pressure. The end of the second preset path is the position where the second locking fitting block 82 forms a locking fit with the second locking block 81. At this time, the second locking member 80 is in the second locking posture, the second pressure cover 40 is locked on the substrate 10 and / or the first pressure cover 30, forming a whole with the substrate 10 and / or the first pressure cover 30, and the second pressing member 70 presses on the second target body.

[0091] In the embodiment provided by the present application, a plurality of guide grooves 83 are provided on the second pressure cover 40, and the plurality of guide grooves 83 correspond one-to-one to the plurality of second locking fitting blocks 82. The second locking fitting block 82 guides and slides in the guide groove 83, and the path of the second locking fitting block 82 moving back and forth along the extension direction of the guide groove 83 is the second preset path. A second locking surface 811 is formed on the second locking block 81, and a second locking fitting surface 821 is formed on the second locking fitting block 82. When the second locking fitting block 82 moves to the end of the second preset path in the guide groove 83, the second locking surface 811 is pressed against the second locking fitting surface 821, so that the second locking member 80 is in the second locking posture, thereby locking the second pressure cover 40 with the substrate 10 and / or the first substrate 10. When it is necessary to separate the second pressure cover 40 from the substrate 10 and / or the first pressure cover 30, the second locking mating block 82 is moved along the guide groove 83 to the initial end of the second preset path, and the state in which the second locking surface 811 and the second locking mating surface 821 are pressed against each other is released, so that the second locking member 80 is in the second unlocking posture.

[0092] In a feasible embodiment, a third elastic member 84 is provided in the guide groove 83, one end of the third elastic member 84 is connected to the inner wall of the guide groove 83, and the other end of the third elastic member 84 is connected to the second locking fitting block 82. When the second locking fitting block 82 moves to the end of the second preset path, the third elastic member 84 undergoes elastic deformation to accumulate elastic force, and the elastic force acts on the second locking fitting block 82, so that the second locking fitting surface 821 and the second locking surface 811 maintain a state of relative pressure, thereby making the second locking member 80 in a second locking posture.

[0093] ReferenceFigure 15 As shown, the second locking mating block 82 is provided with a first through hole 822, and the second locking block 81 can pass through the first through hole 822. The top of the second locking block 81 is provided with a locking protrusion 812, the bottom surface of the locking protrusion 812 is the second locking surface 811, and the top surface of the second locking mating block 82 is the second locking mating surface 821. When the second locking mating block 82 is at the starting end of the second preset path, the second locking surface 811 and the second locking mating surface 821 are staggered with each other. When the second locking mating block 82 moves to the end of the second preset path, the second locking mating surface 821 overlaps with the second locking surface 811, so that the second locking surface 811 is pressed against the second locking mating surface 821.

[0094] Furthermore, under the action of the third elastic member 84, the second locking block 81 and the second locking matching block 82 can maintain a locked state. In order to facilitate the movement of the second locking matching block 82 to the starting end of the second preset path, it is necessary to overcome the elastic force of the third elastic member 84 so that the second locking block 81 and the second locking matching block 82 can be separated. Therefore, a second through hole 823 is also provided on the second locking matching block 82, and a force block 85 is provided in the second through hole 823. When the locking state of the second locking member 80 needs to be released, the force block 85 is pushed, and the force applied by the force block 85 to the second locking matching block 82 causes the second locking matching block 82 to overcome the elastic force of the third elastic member 84, and then move toward the starting end of the second preset path until the second locking surface 811 and the second locking matching surface 821 are misaligned with each other, thereby releasing the locking state of the second locking member 80.
