Description

Technical Field

[0001] The invention relates to the technical field of cabinet hardware frame assembly, and in particular to a cabinet hardware frame positioning and assembly device. Background Art

[0002] The positioning and assembly of cabinet hardware frames is a crucial step in the cabinet installation process, which involves the accurate installation of hardware accessories and the stable construction of the frame structure.

[0003] The cabinet hardware frame is an important part of the cabinet structure. It is mainly composed of hardware accessories and connectors, which are used to support and fix the various parts of the cabinet. The traditional installation method usually requires the collaboration of multiple people. One person is responsible for fixing the hardware frame, and the other is responsible for installing it using fasteners such as screws. This increases the complexity of the operation and the demand for the number of people. In addition, before installation, it is necessary to rely on tools such as rulers and pens for manual measurement and marking to determine the installation position of the hardware frame. This method is not only time-consuming, but also easily affected by human factors, resulting in low positioning accuracy, which in turn affects the overall appearance and use effect of the cabinet. Due to the need for multiple measurements, markings and adjustments, the traditional installation method is often time-consuming and reduces work efficiency. At the same time, multiple adjustments may also cause unnecessary damage to hardware accessories and cabinet materials.

[0078] 1. By integrating multiple structures such as clamping, sliding, pressing, driving, exhausting and controlling, the installation of the hardware frame can be completed by one person, which greatly simplifies the installation process, reduces the manpower demand and the time cost caused by the cooperation of multiple people, and thus significantly improves the installation efficiency. The device is equipped with a first adjustment structure, a second adjustment structure and a position feedback system, so that the staff can accurately adjust the position of the hardware frame without relying on traditional measuring tools. This automatic or semi-automatic adjustment method is not only easy to operate, but also ensures the accuracy of the installation and reduces the errors caused by human factors. In addition, the design of the device has a wide adjustment range and strong versatility, and can adapt to the installation of hardware frames of different specifications and sizes. This flexibility enables the same set of equipment to be used in a variety of scenarios and projects, reducing the equipment cost of the enterprise and improving the utilization rate and economic benefits of the equipment;

[0079] 2. By setting the clamping structure on the fixed seat and combining the sliding ability of the fixed seat on the guide rail, the hardware frame can be smoothly and accurately moved to the middle position of the mounting frame during the clamping process. This design not only improves the positioning accuracy of the hardware frame, but also ensures the stability of the moving process and avoids the skew problem caused by improper manual operation;

[0080] 3. The close fit between the damping cylinder and the damping sleeve made of rubber material generates a large friction force, which effectively limits the non-human rotation of the shaft, thereby ensuring that the sliding frame can maintain a stable position when it does not need to move, avoiding the position deviation of the sliding frame caused by accidental touch or vibration. Due to the existence of damping, the staff can more accurately control the moving distance and angle of the sliding frame when adjusting the position of the sliding frame, reducing the installation error caused by the accidental movement of the sliding frame, and improving the accuracy and efficiency of the hardware frame installation;

[0081] 4. By simply pulling and turning the U-shaped rod, the gas in the suction cup can be extracted and fixed, as well as the subsequent unlocking and releasing. This greatly simplifies the operation steps and improves work efficiency. The frame does not need to be fixed by gluing or punching or other methods. By using the negative pressure principle, the suction cup can be firmly adsorbed on the surface of the cabinet door to ensure that the frame will not fall off easily due to external force during the fixation period, thereby enhancing the safety and stability during the work process. In addition, the slot design between the U-shaped rod and the card head realizes the automatic locking function. Once the U-shaped rod is in place, it can automatically fit into the slot under the action of the spring force, and can remain fixed without additional operation, thus avoiding looseness caused by misoperation. The stable adsorption of the frame provides guarantee for the accurate positioning of the hardware frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0098] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0099] Reference Figure 1-15A cabinet hardware frame positioning and assembly device comprises a frame 1, both ends of which are open structures; a level 2, mounted on the top surface of the frame 1; two sliding frames 3, respectively slidably arranged at both ends of the frame 1, each of the sliding frames 3 having an opening; two suction cups 4, respectively fixed in the two openings;

[0100] The hardware frame positioning assembly device also includes a first adjustment structure, which is arranged on the frame body 1 and is used to adjust the positions of the two sliding frames 3. The first adjustment structure includes: a rotating shaft 51 (such as Fig.12 As shown), it passes through the frame 1 and is rotatably connected with the frame 1; the gear 52 is fixedly sleeved on one end of the rotating shaft 51 located inside the frame 1; the two racks 53 are respectively fixed on the two sliding frames 3, and each rack 53 is meshed with the gear 52; the damping cylinder 54 is fixed on the inner surface of the frame 1, and one end of the rotating shaft 51 extends to the inside of the damping cylinder 54; the damping sleeve 55 is fixedly sleeved on the rotating shaft 51 and is located inside the damping cylinder 54. The staff turns the knob on the rotating shaft 51 to rotate the rotating shaft 51. When the rotating shaft 51 rotates, it can drive the gear 52 to rotate. When the gear 52 rotates, it can drive the two racks 53 meshing with it to move, and the two sliding frames 3 will also move accordingly, so the rotating shaft 51 rotates. When the shaft 51 rotates, the two sliding frames 3 can approach or move away from each other, and the staff can quickly adjust the positions of the two sliding frames 3 by rotating the rotating shaft 51. It is worth mentioning that a damping cylinder 54 is fixed in the frame 1, and a damping sleeve 55 is sleeved on the rotating shaft 51. The damping sleeve 55 is located in the damping cylinder 54, and the outer surface of the damping sleeve 55 and the inner surface of the damping cylinder 54 fit each other. In addition, the damping cylinder 54 and the damping sleeve 55 are both made of rubber material, which makes the damping cylinder 54 and the damping sleeve 55 have a large friction force. The friction force can provide a damping effect on the rotating shaft 51, so that the rotating shaft 51 will not rotate under non-human action, thereby ensuring the position stability of the two sliding frames 3;

[0101] The hardware frame positioning assembly device also includes a second adjustment structure, which is arranged on the bottom surface of the frame body 1. The second adjustment structure includes: two side plates 61, which are respectively fixed at the two ends of the bottom surface of the frame body 1; a first adjustment screw 62, which is rotatably installed between the two side plates 61; a first guide rod 63, which is fixed between the two side plates 61; an adjustment plate 64, which is threadedly sleeved on the first adjustment screw 62 and slidably sleeved on the first guide rod 63;

[0102] The hardware frame positioning and assembling device also includes a clamping structure, which is arranged on the second adjustment structure and is used to clamp and fix the hardware frame. The clamping structure includes: a mounting frame 71, which is fixed to the side of the adjustment plate 64 and has a U-shaped structure; a second adjustment screw 72, which is rotatably mounted on the mounting frame 71, and the second adjustment screw 72 is provided with two threaded sections of the same length and opposite directions; a second guide rod 73, which is fixed on the mounting frame 71; two clamping plates 74, which are respectively threadedly sleeved on the two threaded sections of the second adjustment screw 72, and the two clamping plates The second adjusting screw 72 is provided with two threaded sections of the same length and in opposite directions. Therefore, under the limiting effect of the second guide rod 73, the second adjusting screw 72 can drive the two clamping plates 74 to approach each other when rotating, until the two clamping plates 74 clamp the hardware frame together. At this time, the two clamping plates 74 play a fixing role on the hardware frame, further improving the stability of the hardware frame on the cabinet door.

[0103] The hardware frame positioning assembly device also includes a sliding structure, which is arranged on the side of the frame body 1. The sliding structure includes a guide rail 81, a slide seat 82 and a fixed seat 83 (such as Figure 5 As shown), the guide rail 81 is fixed to the side of the mounting frame 71, the slide seat 82 is slidably arranged on the guide rail 81, and the fixed seat 83 is fixed to the side of the slide seat 82;

[0104] The hardware frame positioning and assembling device also includes a clamping structure, which is arranged on the fixing seat 83 and is used to clamp and fix the hardware frame. The clamping structure includes: an outer cylinder 91, which is fixed to the side of the fixing seat 83, and a hole is opened at one end of the outer cylinder 91 away from the fixing seat 83; a first sliding plug 92 (such as Fig.14 As shown), the sealing sliding connection is in the outer cylinder 91; the first spring 93, one end of which is connected to the outer cylinder 91, and the other end is connected to the first sliding plug 92; the inner rod 94, one end of which is fixed on the first sliding plug 92, and the other end passes through the hole; the clamping plate 95, which is fixed to the end of the inner rod 94 outside the outer cylinder 91, and has an L-shaped structure; the limiting plate 96, which is fixed to the side of the fixing seat 83; the limiting slide 97, which is opened on the limiting plate 96; the limiting frame 98, which is fixed to the side of the clamping plate 95, and has an L-shaped structure, and the limiting frame 98 slides in the limiting slide 97; two limiting sleeves 99, which are fixedly sleeved on the limiting frame 98, and are respectively located at the upper and lower ends of the limiting plate 96;

[0105] The hardware frame positioning assembly device also includes a driving structure, which is arranged on the fixing seat 83 and is used to control the operation of the pressing structure. The driving structure includes: a sealing cylinder 101 (such as Fig.13 As shown), fixed on the top surface of the fixing seat 83, one end of which is provided with a through hole; the second sliding plug 102 (as shown Fig.15As shown), the sealing sliding connection is in the sealing cylinder 101; the second spring 103, one end of which is connected to the inner surface of the sealing cylinder 101, and the other end is connected to the second sliding plug 102; the connecting pipe 104, one end of which is connected to the sealing cylinder 101 (as shown Fig.11 As shown), the other end is connected to the outer tube 91; a pull rod 105, one end of which is fixed on the second sliding plug 102, and the other end passes through the through hole. When the pull rod 105 moves, it drives the second sliding plug 102 to move. When the second sliding plug 102 moves, it can extract the gas in the outer tube 91 through the connecting pipe 104. When the gas in the outer tube 91 is extracted, the first sliding plug 92 will move under the action of the pressure difference and drive the inner rod 94 to move. When the inner rod 94 moves, it can drive the pressing plate 95 to move toward the cabinet door, so that the pressing plate 95 presses the hardware frame, and the hardware frame can be pressed on the cabinet door;

[0106] The hardware frame positioning assembly device also includes a positioning structure, which is arranged on the fixed seat 83 and is used to provide positioning for the driving structure. The positioning structure includes: a fixed block 111, fixed to one end of the pull rod 105 located outside the sealing cylinder 101; a first clamping block 112, fixed to the bottom surface of the fixed block 111, and the first clamping block 112 is provided with an inclined surface; a slot 113, which is provided on the top surface of the fixed seat 83; a lifting block 114, which slides in the slot 113, and the top end extends to the outside of the slot 113; a cross plate 115, which is fixed to the top of the lifting block 114; a third spring 116, one end of which is connected to the bottom of the slot 113, and the other end is connected to the lifting block 114; a sliding port 117, which is provided on the side of the fixed seat 83 and is connected to the slot 113; a plurality of second clamping blocks 118, all of which are fixed to the top surface of the cross plate 115, and each second clamping block 118 is provided with an inclined surface When the first clamping block 112 and the second clamping block 118 are pressed against each other, the second clamping block 118 will move downward, so that the cross plate 115 and the lifting block 114 will move downward. When the first clamping block 112 moves to the position between two adjacent second clamping blocks 118, the first clamping block 112 will no longer press the second clamping block 118. At this time, the lifting block 114, the cross plate 115 and the second clamping blocks 118 will move up and reset under the action of the third spring 116. In summary, the first clamping block 112 and the second clamping blocks 118 play a one-way locking role on the movement of the fixed block 111, thereby preventing the fixed block 111 from rebounding and resetting under the action of the second spring 103.

[0107] The hardware frame positioning assembly device also includes two position feedback structures, which are respectively arranged on the two sliding frames 3. The position feedback structure includes: a sleeve 121, which is fixed to the side of the sliding frame 3 and has an open structure at one end; a marking rod 122 (such as Fig.10As shown), slides in the sleeve 121, one end of the identification rod 122 extends to the outside of the sleeve 121 and is fixedly connected to the mounting frame 71, and the surface of the identification rod 122 is provided with scale lines. When the mounting frame 71 moves, it can drive the two identification rods 122 to move. The two identification rods 122 are provided with scale lines. The staff can accurately control the position of the hardware frame through the scale lines set on the two identification rods 122;

[0108] That is to say, when a reference point of the hardware frame is located in the middle of the mounting frame 71, the scale lines of the two sleeves 121 aligned on their respective identification rods 122 are the same, which constitutes a clear center reference point. By observing and comparing the scale lines of the two sleeves 121 aligned on the identification rods 122, the current position of the hardware frame can be quickly determined. If the scale lines on both sides are aligned, the hardware frame is centered; if the scale line on one side is forward (or backward) than the other side, the hardware frame is offset to the left (or right) accordingly. This design utilizes visual intuition, so that the operator can accurately determine and adjust the position of the hardware frame based on the alignment of the scale lines without complicated measuring tools or calculations.

[0109] The hardware frame positioning assembly device also includes two suction structures, which are respectively arranged on the two suction cups 4. The suction structure includes: a fixed cylinder 131 (such as Fig. 9 As shown in the figure, the fourth spring 134 is fixedly connected to the suction cup 4, one end of which is provided with a through hole, and the fixed cylinder 131 is connected to the suction cup 4; the third sliding plug 132 is sealingly slidably connected in the fixed cylinder 131; the fixed rod 133 is fixedly connected to the third sliding plug 132 at one end, and the other end passes through the through hole; the fourth spring 134 is connected to the fixed cylinder 131 at one end, and connected to the third sliding plug 132 at the other end;

[0110] The hardware frame positioning assembly device also includes a control structure, which is arranged on the side of the frame 1. The control structure includes: two cross bars 141 (such as Fig.10As shown in the figure, the ends of the two cross bars 141 away from each other are fixed on the two fixed bars 133 respectively; the U-shaped bar 142 is rotatably mounted on the ends of the two cross bars 141 close to each other; the support bar 143 is fixed to the side of the frame 1; the clamping head 144 is fixed to the end of the support bar 143 away from the frame 1, and a clamping groove is provided on the clamping head 144. The staff first pulls the U-shaped bar 142 to make the U-shaped bar 142 drive the two cross bars 141 to move. When the two cross bars 141 move, they can drive the two fixed bars 133 to move, so that the two third sliding plugs 132 move synchronously. When the two third sliding plugs 132 move, they can perform a vacuum action and draw the gas in the two suction cups 4 into the two fixed cylinders 131, so that the two suction cups 4 are adsorbed on the surface of the cabinet door under the action of negative pressure. The frame 1 can be fixed on the cabinet door. When the U-shaped rod 142 is rotated to a position in contact with the clamping head 144, the staff can rotate the U-shaped rod 142 to make the U-shaped rod 142 bypass the clamping head 144. When the U-shaped rod 142 moves to bypass the clamping head 144, the staff adjusts the U-shaped rod 142 to a horizontal position so that the U-shaped rod 142 is directly opposite to the slot on the clamping head 144. Then, the staff releases the U-shaped rod 142, and the U-shaped rod 142 and the two cross bars 141 are reset under the action of the two fourth springs 134, so that the U-shaped rod 142 is stuck in the slot. At this time, the clamping head 144 fixes the position of the U-shaped rod 142, and the positions of the two third slide plugs 132 are also fixed. This design is convenient for the staff to use two suction cups 4 to quickly fix the frame 1.

[0111] The specific working principle of the present invention is as follows:

[0112] When the cabinet hardware frame positioning and assembling device proposed by the present invention is used, the staff first fixes the frame 1 on the cabinet door. Specifically, the staff aligns the top of the level 2 with the top of the cabinet door, and controls the horizontality of the frame 1 through the level 2 to make the frame 1 in a horizontal state. Then, the staff adjusts the positions of the two sliding frames 3 through the first adjustment structure to move the two sliding frames 3 to the positions aligned with the two sides of the cabinet door. Specifically, the staff turns the knob on the rotating shaft 51 to rotate the rotating shaft 51. When the rotating shaft 51 rotates, it can drive the gear 52 to rotate. When the gear 52 rotates, it can drive the two racks 53 meshing with each other to move, and the two sliding frames 3 will also move accordingly, so When the rotating shaft 51 rotates, the two sliding frames 3 can approach or move away from each other. The staff can quickly adjust the positions of the two sliding frames 3 by rotating the rotating shaft 51. It is worth mentioning that a damping cylinder 54 is fixed in the frame 1, and a damping sleeve 55 is sleeved on the rotating shaft 51. The damping sleeve 55 is located in the damping cylinder 54, and the outer surface of the damping sleeve 55 and the inner surface of the damping cylinder 54 are in contact with each other. In addition, the damping cylinder 54 and the damping sleeve 55 are both made of rubber material, which makes the damping cylinder 54 and the damping sleeve 55 have a large friction force. The friction force can provide a damping effect on the rotating shaft 51, so that the rotating shaft 51 will not rotate under non-human action, thereby ensuring the position stability of the two sliding frames 3;

[0113] After adjusting the horizontality of the frame 1 and the positions of the two sliding frames 3, the staff uses the control structure and the suction structure to extract the gas in the two suction cups 4, so that the frame 1 is adsorbed on the cabinet door under the action of the two suction cups 4. Specifically, the staff first pulls the U-shaped rod 142 to make the U-shaped rod 142 drive the two cross bars 141 to move. When the two cross bars 141 move, they can drive the two fixed rods 133 to move, so that the two third sliding plugs 132 move synchronously. When the two third sliding plugs 132 move, they can perform a suction action and draw the gas in the two suction cups 4 into the two fixed cylinders 131, so that the two suction cups 4 are adsorbed on the surface of the cabinet door under the action of negative pressure, and the frame 1 can be fixed on the cabinet door. When the U-shaped rod 14 2 is rotated to a position in contact with the clamping head 144, the staff can rotate the U-shaped rod 142 to make the U-shaped rod 142 bypass the clamping head 144. When the U-shaped rod 142 moves to bypass the clamping head 144, the staff adjusts the U-shaped rod 142 to a horizontal position so that the U-shaped rod 142 is directly opposite to the clamping groove on the clamping head 144. Then, the staff releases the U-shaped rod 142, and the U-shaped rod 142 and the two cross bars 141 are reset under the action of the two fourth springs 134, so that the U-shaped rod 142 is clamped into the clamping groove. At this time, the clamping head 144 fixes the position of the U-shaped rod 142, and the positions of the two third sliding plugs 132 are also fixed. This design is convenient for the staff to use the two suction cups 4 to quickly fix the frame 1;

[0114] After fixing the frame 1, the staff fits the hardware frame on the cabinet door and moves the top of the hardware frame to a position facing the clamping plate 95, and then uses the driving structure, the positioning structure and the clamping structure to clamp the hardware frame on the cabinet door. Specifically, the staff first pulls the fixing block 111 to make the fixing block 111 drive the pull rod 105 to move. When the pull rod 105 moves, it drives the second sliding plug 102 to move. When the second sliding plug 102 moves, it can extract the gas in the outer cylinder 91 through the connecting pipe 104. When the gas in the outer cylinder 91 is extracted, the first sliding plug 92 will move under the action of the pressure difference and drive the inner rod 94 to move. When the inner rod 94 moves, it can drive the pressing plate 95 to move toward the cabinet door, so that the pressing plate 95 presses the hardware frame, and the hardware frame can be pressed on the cabinet door. In addition, during the movement of the fixing block 111, the first clamping block 112 will squeeze the multiple second clamping blocks 118 one by one. When the inclined surface of the first clamping block 112 and the inclined surface of the second clamping block 118 squeeze each other, the second clamping block 118 will move downward, so that the cross plate 115 and the lifting block 114 move downward. When the first clamping block 112 moves to the position between two adjacent second clamping blocks 118, the first clamping block 112 no longer squeezes the second clamping block 118. At this time, the lifting block 114, the cross plate 115 and the second clamping blocks 118 will move up and reset under the action of the third spring 116. In summary, the first clamping block 112 and the second clamping blocks 118 play a one-way locking role on the movement of the fixed block 111, preventing the fixed block 111 from rebounding and resetting under the action of the second spring 103. When the fixed block 111 is fixed, the position of the second sliding plug 102 will also be fixed. Further, the positions of the first sliding plug 92 and the clamping plate 95 will also be fixed, which can ensure the clamping effect of the clamping plate 95 on the hardware frame and ensure the stability of the hardware frame on the cabinet door. It is necessary to contact with When the fixed block 111 is locked, the staff pulls down the protrusion 119, so that the protrusion 119 drives the lifting block 114 to move downward. When the lifting block 114 moves downward, it can drive the cross plate 115 and a plurality of second clamping blocks 118 to move downward, so that the second clamping block 118 is separated from the first clamping block 112. Without the restriction of the second clamping block 118, the first clamping block 112 and the fixed block 111 will be reset under the action of the second spring 103, so that the second sliding plug 102 is reset. When the second sliding plug 102 is reset, it can push the gas into the outer cylinder 91 through the connecting pipe 104, so that the first sliding plug 92 also performs a reset movement, and the pressing plate 95 will also be reset accordingly;

[0115] The second adjusting screw 72 has two threaded sections of the same length and in opposite directions. Therefore, under the limiting action of the second guide rod 73, the second adjusting screw 72 can drive the two clamping plates 74 to approach each other when rotating, until the two clamping plates 74 clamp the hardware frame together. At this time, the two clamping plates 74 fix the hardware frame, further improving the stability of the hardware frame on the cabinet door. When the hardware frame is fixed, the worker The staff can use screws to fix the hardware frame on the cabinet door. It should be noted that the clamping structure is arranged on the fixing seat 83, and the fixing seat 83 is arranged on the mounting frame 71 through the guide rail 81 and the slide seat 82, so that the fixing seat 83 and the clamping structure thereon can slide. The two clamping plates 74 can move the hardware frame to the middle position of the mounting frame 71 when the two clamping plates 74 approach each other. When the hardware frame moves, the fixing seat 83 can be driven to slide through the clamping plate 95. Therefore, the slidable characteristic of the fixing seat 83 facilitates the movement of the hardware frame when it is pressed, and avoids the skewness of the hardware frame during the movement.

[0116] After fixing the hardware frame, the staff can also fine-tune the position of the hardware frame through the second adjustment structure so that the hardware frame is adjusted to the preset installation position. Specifically, the staff turns the knob on the first adjusting screw 62 to rotate the first adjusting screw 62. Under the limiting action of the first guide rod 63, the first adjusting screw 62 can drive the adjusting plate 64 to move when it rotates. When the adjusting plate 64 moves, it can drive the mounting bracket 71 to move, and the components set on the mounting bracket 71 will also move accordingly. When the mounting bracket 71 moves, the two clamping plates 74 can drive the hardware frame to move. Therefore, the staff can fine-tune the position of the hardware frame by rotating the first adjusting screw 62. Furthermore, when the mounting bracket 71 moves, it can drive the two identification rods 122 to move. Both identification rods 122 are provided with scale lines. The staff can accurately control the position of the hardware frame through the scale lines set on the two identification rods 122.

[0117] To sum up, with the coordinated action of the clamping structure, sliding structure, clamping structure, driving structure, exhaust structure and control structure, a worker can install the hardware frame alone, without the need for multiple workers to cooperate in the operation, thereby reducing personnel requirements. In addition, the device has the function of providing positioning for the hardware frame. The worker can accurately adjust the position of the hardware frame through the first adjustment structure, the second adjustment structure and the position feedback structure. There is no need to use measuring tools such as rulers to adjust the installation position of the hardware frame. The operation is convenient and the positioning is accurate, thereby achieving the purpose of improving the installation efficiency of the hardware frame. Secondly, the device has a wide adjustable range and strong versatility, and can position and install hardware frames of different specifications.
