Description

Technical Field

[0001] This utility model relates to the field of handle installation technology, and in particular to a handle pressing device. Background Technology

[0002] A handle is a component used for lifting and carrying, typically installed on various boxes, bags, and other items to facilitate movement or transport. Before installing the handle, a mounting plate must be fastened to it to ensure a secure connection. In existing technology, the handle has multiple fasteners, and the mounting plate has multiple holes. Workers must first align the holes on the mounting plate with the fasteners on the handle, then press the mounting plate firmly to engage the fasteners. This repetitive and prolonged pressure on the mounting plate can easily cause hand fatigue and injury, thus failing to reduce the intensity of manual labor. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a handle pressing device, which helps reduce the labor intensity of workers' hands.

[0004] The handle pressing device according to an embodiment of the present utility model includes a base, a positioning block, a lifting drive component, and an ejection device.

[0005] A positioning block is disposed on the base, and the positioning block is provided with a positioning groove for inserting a handle. A lifting drive is disposed on the base, and the output end of the lifting drive is provided with a pressure block. The pressure block is provided with multiple clearance holes, which are respectively used for multiple fasteners on the handle to extend into. The lifting drive can drive the pressure block to descend, so that the pressure block presses down on the mounting plate and fastens the mounting plate to the handle. An ejection device is disposed on the base, and the ejection device is used to lift the handle in the positioning groove so that the upper end of the handle extends out of the positioning groove.

[0006] It has at least the following beneficial effects:

[0007] When attaching the mounting plate to the handle, the worker first places the handle into the positioning groove on the positioning block, ensuring the inner wall of the groove positions the handle and that the multiple clearance holes on the pressure block align with the fasteners on the handle. Next, the worker places the mounting plate on the handle, allowing the fasteners on the handle to pass through the multiple buckle holes on the mounting plate. At this point, the fasteners abut against the walls of the buckle holes, supporting the mounting plate. The worker then activates the lifting drive, which lowers the pressure block. As the block descends, the fasteners on the handle extend into the clearance holes on the pressure block. With continued descent, the pressure block presses down on the mounting plate, forcing the fasteners through the buckle holes to complete the mounting plate's attachment. After the mounting plate is fastened, the worker activates the ejection device, which lifts the handle from the positioning slot, allowing the upper end of the handle to extend out of the slot so the worker can remove the fastened handle. This handle pressing device replaces the step of the worker pressing the mounting plate forcefully, avoiding fatigue and injury to the worker's hands caused by repeated forceful pressing of the mounting plate over a long period of time, thus reducing the labor intensity of the worker's hands.

[0008] The handle pressing device according to an embodiment of the present invention further includes a linear drive, a first guide rod, and a second guide rod.

[0009] According to the handle pressing device of this utility model embodiment, the upper end of the first guide rod is provided with a support surface, and the upper end of the first guide rod abuts against the handle in the positioning groove through the support surface.

[0010] The handle pressing device according to an embodiment of the present utility model further includes a second foot switch, which is electrically connected to the linear drive member. When the second foot switch is pressed, the linear drive member drives the second guide rod to move backward, and when the second foot switch is released, the linear drive member drives the second guide rod to move forward.

[0011] The handle pressing device according to an embodiment of the present utility model further includes a positioning float and a plurality of elastic elements.

[0034] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] refer to Figures 1 to 5 This utility model discloses a handle pressing device, including a base 400, a positioning block 100, a lifting drive component 410 and an ejection device 200.

[0037] A positioning block 100 is disposed on the base 400, and a positioning groove 130 is provided on the positioning block 100 for inserting the handle 10. A lifting drive 410 is disposed on the base 400, and a pressure block 420 is provided at the output end of the lifting drive 410. The pressure block 420 is provided with multiple clearance holes, which are respectively used for multiple fasteners 11 on the handle 10 to extend into. The lifting drive 410 can drive the pressure block 420 to descend, so that the pressure block 420 presses down on the mounting plate 20 and fastens the mounting plate 20 onto the handle 10. An ejection device 200 is disposed on the base 400, and the ejection device 200 is used to lift the handle 10 in the positioning groove 130, so that the upper end of the handle 10 extends out of the positioning groove 130.

[0038] In this embodiment of the invention, the lifting drive component 410 is a lifting cylinder. The cylinder body of the lifting cylinder is connected to the base 400, and the piston rod of the lifting cylinder is connected to the pressure block 420. The handle pressing device also includes a first foot switch 430, which is electrically connected to the lifting cylinder. When the first foot switch 430 is pressed down by the worker, the lifting cylinder drives the pressure block 420 to descend and approach the positioning block 100. When the first foot switch 430 is released by the worker, the lifting cylinder drives the pressure block 420 to rise and move away from the positioning block 100. In this embodiment of the invention, the shape of the positioning groove 130 is consistent with the shape of the handle 10, so that the inner wall of the positioning plate can completely abut against the handle 10, ensuring that the inner wall of the positioning groove 130 can stably position the handle 10.

[0039] Understandably, when the mounting plate 20 needs to be fastened onto the handle 10, the worker can first place the handle 10 into the positioning groove 130 on the positioning block 100, so that the inner wall of the positioning groove 130 can position the handle 10, ensuring that the multiple clearance holes on the pressure block 420 can be aligned with the multiple fasteners 11 on the handle 10. Next, the worker can place the mounting plate 20 onto the handle 10, so that the multiple fasteners 11 on the handle 10 pass through the multiple fastening holes on the mounting plate 20. At this time, the multiple fasteners 11 abut against the walls of the multiple fastening holes, allowing the multiple fasteners 11 to support the mounting plate 20. Then, the worker activates the lifting drive 410, which drives the pressure block 420 to descend. During the descent of the pressure block 420, multiple fasteners 11 on the handle 10 can extend into multiple clearance holes on the pressure block 420. As the pressure block 420 continues to descend, it abuts against and presses down on the mounting plate 20. Under the pressing action of the pressure block 420, the multiple fasteners 11 on the handle 10 pass through multiple buckle holes on the mounting plate 20 to complete the fastening of the mounting plate 20. After the mounting plate 20 is fastened, the worker activates the ejector device 200, which lifts the handle 10 from the positioning groove 130, allowing the upper end of the handle 10 to extend out of the positioning groove 130 so that the worker can remove the fastened handle 10 from the positioning groove 130. This handle pressing device replaces the step of the worker pressing the mounting plate 20 forcefully, avoiding fatigue and injury to the worker's hands due to repeated forceful pressing of the mounting plate 20 over a long period of time, thus reducing the labor intensity of the worker's hands.

[0040] refer to Figure 3 , Figure 4 and Figures 6 to 8The handle pressing device also includes a linear drive 230, a first guide rod 210, and a second guide rod 220. The first guide rod 210 is parallel to the vertical direction, and the second guide rod 220 is parallel to the front-back direction. A first guide hole 110 parallel to the vertical direction is opened on the inner bottom wall of the positioning groove 130, and a second guide hole 120 parallel to the front-back direction is opened on the positioning block 100. The first guide hole 110 and the second guide hole 120 are connected. The first guide rod 210 and the second guide rod 220 can slide through the first guide hole 110 and the second guide rod 220 respectively. Within the first guide rod 210 and the second guide hole 120, the lower end of the first guide rod 210 is provided with a first guide slope 211, and the rear end of the second guide rod 220 is provided with a second guide slope 221. A linear drive unit 230 is mounted on the base 400, and its output end is connected to the front end of the second guide rod 220. The linear drive unit 230 can drive the second guide rod 220 to move backward, so that the second guide slope 221 abuts against the first guide slope 211, and the first guide rod 210 pushes upward to lift the handle 10 within the positioning groove 130. It can be understood that after the mounting plate 20 is fastened, the worker activates the linear drive unit 230, which drives the second guide rod 220 to move backward. Since the first guide slope 211 on the first guide rod 210 and the second guide slope 221 on the second guide rod 220 abut against each other, and the first guide slope 211 and the second guide slope 221 have a guiding function, the first guide rod 210 rises under the backward push of the second guide rod 220, so that the upper end of the first guide rod 210 extends into the positioning groove 130 and pushes the handle 10 upward, thereby causing the upper end of the handle 10 to extend out of the positioning groove 130 so that the worker can take the handle 10 out of the positioning groove 130.

[0041] After the worker removes the handle 10 from the positioning slot 130, the linear drive 230 drives the second guide rod 220 forward. At this time, the first guide rod 210 gradually descends under its own weight and completely enters the first guide hole 110, so that the worker can place the next handle 10 into the positioning slot 130. In this embodiment of the invention, the cross-sections of the first guide hole 110, the second guide hole 120, the first guide rod 210, and the second guide rod 220 are all rectangular to prevent the first guide rod 210 and the second guide rod 220 from rotating within the first guide hole 110 and the second guide hole 120, respectively. In this embodiment of the invention, the linear drive 230 is a linear cylinder. The handle pressing device also includes a second foot switch, which is electrically connected to the linear drive 230. When the second foot switch is pressed, the linear drive 230 drives the second guide rod 220 to move backward; when the second foot switch is released, the linear drive 230 drives the second guide rod 220 to move forward. The cylinder body of the linear cylinder is mounted on the base 400, and the piston rod of the linear cylinder is connected to the front end of the second guide rod 220. It can be understood that when the worker presses the second foot switch, the linear cylinder drives the second guide rod 220 to move back and forth; when the worker releases the second foot switch, the second guide rod 220 moves forward. Further details are omitted here. (Reference) Figure 6 The upper end of the first guide rod 210 is provided with a support surface 212, and the upper end of the first guide rod 210 abuts against the handle 10 in the positioning groove 130 through the support surface 212. It can be understood that by abutting the handle 10 through the support surface 212, the contact area between the first guide rod 210 and the handle 10 is increased, allowing the first guide rod 210 to more stably lift the handle 10. Specifically, the support surface 212 is a V-shaped support surface with an upward-facing angle.

[0042] refer to Figure 4 and Figure 5The handle pressing device also includes a positioning float 300 and multiple elastic elements 340. The positioning float 300 is connected to the positioning block 100 by the multiple elastic elements 340, which can float up and down. The positioning float 300 has mating holes 330 for the handle 10 to pass through and be placed into the positioning groove 130. The positioning float 300 is used to position the mounting plate 20 so that the multiple buckle holes on the mounting plate 20 are respectively aligned with the multiple fasteners 11 on the handle 10. It can be understood that when the mounting plate 20 needs to be fastened to the handle 10, the worker can directly pass the handle 10 through the mating hole 330 on the positioning float 300 and place it into the positioning groove 130 on the positioning block 100, so that the inner wall of the positioning groove 130 can position the handle 10 and ensure that the multiple clearance holes on the pressing block 420 can be respectively aligned with the multiple fasteners 11 on the handle 10. Next, the worker can directly place the mounting plate 20 on the positioning float 300. The positioning float 300 can position itself, allowing the multiple buckle holes on the mounting plate 20 to align with the multiple fasteners 11 on the handle 10 within the positioning groove 130. Then, the worker activates the lifting drive 410, which drives the pressure block 420 to descend. As the pressure block 420 presses down on the mounting plate 20, multiple elastic elements 340 are compressed, causing the positioning float 300 to descend along with the mounting plate 20. Once all the multiple fasteners 11 on the handle 10 have passed through the mating holes 330 on the positioning float 300, and all the multiple fasteners 11 have passed through the multiple buckle holes on the mounting plate 20, the mounting plate 20 is successfully fastened. The positioning float 300 can position the mounting plate 20, so that the multiple buckle holes on the mounting plate 20 can be quickly aligned with the multiple fasteners 11 on the handle 10. This avoids the need for workers to repeatedly adjust the position of the mounting plate 20 to align the buckle holes with the fasteners 11, shortens the positioning time of the mounting plate 20, and improves the fastening efficiency of the mounting plate 20.

[0043] It should be explained that after the worker places the handle 10 into the positioning slot 130, the positioning float 300 is positioned above the multiple fasteners 11 on the handle 10. After the worker removes the handle 10 from the positioning slot 130, the multiple elastic elements 340 extend and lift the positioning float 300 back to its original position; this will not be elaborated further here. The handle pressing device also includes multiple third guide rods 350. The positioning block 100 has multiple third guide holes. The upper ends of the multiple third guide rods 350 are connected to the positioning float 300, and the lower ends of the multiple third guide rods 350 are respectively inserted into the multiple third guide holes. The multiple elastic elements 340 are respectively sleeved on the multiple third guide rods 350. It is understood that the upper ends of the multiple third guide rods 350 are connected to the positioning float 300, and the lower ends of the multiple third guide rods 350 can slide up and down through multiple third guide holes, so that the third guide rods 350 can guide the up and down movement of the positioning float 300, thereby enabling the positioning float 300 to move up and down stably. Multiple elastic elements 340 are respectively sleeved on the multiple third guide rods 350, so that the third guide rods 350 can guide the compression and extension of the elastic elements 340, ensuring that the elastic elements 340 can compress and extend in the up and down direction. In this embodiment of the present invention, the elastic element 340 can be a compression spring, the upper ends of multiple compression springs are connected to the positioning float 300, and the lower ends of multiple compression springs are respectively connected to the inner bottom wall of multiple third guide holes, which will not be further elaborated here.

[0044] refer to Figure 4 and Figure 5 The positioning float 300 is provided with two first positioning protrusions 310 and two second positioning protrusions 320. The two first positioning protrusions 310 are respectively located on the front and rear sides of the mating hole 330, and the two second positioning protrusions 320 are respectively located on the left and right sides of the mating hole 330. The area enclosed by the positioning float 300, the two first positioning protrusions 310, and the two second positioning protrusions 320 is used for the mounting plate 20 to be inserted. It can be understood that the upper surface of the positioning float 300, the two first positioning protrusions 310, and the two second positioning protrusions 320 together enclose a positioning area. The worker only needs to place the mounting plate 20 into this positioning area to quickly complete the positioning of the mounting plate 20, so that the multiple buckle holes on the mounting plate 20 can be aligned with the multiple fasteners 11 on the handle 10. The two first positioning protrusions abut against the front and rear sides of the mounting plate 20 on opposite sides, and the two second positioning protrusions abut against the left and right sides of the mounting plate 20 on opposite sides, thus enabling the two first positioning protrusions and the two second positioning protrusions to position the mounting plate 20. (Reference) Figure 5Each of the two first positioning protrusions 310 has a third guide slope 311 on one side opposite to it. The included angle formed by the two third guide slopes 311 faces upward, and both third guide slopes 311 are used to abut against the mounting plate 20. Each of the two second positioning protrusions 320 has a fourth guide slope 321 on one side opposite to it. The included angle formed by the two fourth guide slopes 321 faces upward, and both fourth guide slopes 321 are used to abut against the mounting plate 20. It can be understood that during the process of the worker placing the mounting plate 20 into the positioning area, both the two third guide slopes 311 and the two fourth guide slopes 321 can abut against the mounting plate 20, that is, the third guide slopes 311 and the fourth guide slopes 321 can guide the placement of the mounting plate 20, making it easier for the worker to place the mounting plate 20 into the positioning area.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
