[0004] In the aforementioned prior art, the threaded rod can be screwed into the pipe pile mold to fix the upper and lower molds. However, in order to ensure the connection stability of the threaded rod, the tightening operation of the threaded rod usually requires the use of power tools such as power wrenches. Power tools are large and heavy, and the operation requires the operator to repeatedly lift and pull, which will accelerate the consumption of manual labor and affect the processing efficiency. Therefore, a new locking mechanism for pipe pile production molds is needed to meet people's needs. Summary of the Invention

Power tools are large and heavy, and require workers to repeatedly lift and pull them during operation, which will accelerate the consumption of manual labor and affect processing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel locking mechanism for a pipe pile production mold, comprising a pipe pile mold and a mold cover plate, wherein a mold edge strip one is provided on the pipe pile mold, and a mold edge strip two is provided on the mold cover plate; a mold frame is movably mounted on the pipe pile mold, a plurality of positioning screws are installed on the mold edge strip one, a plurality of insertion holes are opened in the mold edge strip two, the positioning screws are inserted into the corresponding insertion holes, a locking structure is connected to the positioning screws, a slide is installed on one side of the mold frame, a tightening structure is connected to the slide, a connecting frame is connected to the tightening structure, and a positioning structure is connected to the connecting frame.

[0007] Preferably, the locking structure includes a connecting nut, which is threaded onto the positioning screw. A limit guide rod is installed on the inner wall of the first mold strip. An L-shaped stop rod is slidably fitted on the limit guide rod. The L-shaped stop rod has an inclined surface. Several slots are opened on the second mold strip, and the slots correspond to the L-shaped stop rods. An umbrella-shaped pressure ring is installed on one side of the connecting nut. The umbrella-shaped pressure ring is located above the inclined surface of the L-shaped stop rod.

[0008] Preferably, a spring is movably sleeved on the positioning screw, with both ends of the spring contacting the umbrella-shaped pressure ring and the mold edge strip 2, respectively. A spring 2 is slidably sleeved on the limiting guide rod, with one end of the spring 2 installed on the inner wall of the mold edge strip 1 and the other end of the spring 2 installed on one side of the L-shaped stop bar.

[0009] Preferably, the tightening structure includes a slide table, which is movably mounted above the slide frame. A U-shaped frame is mounted above the slide table, and a Z-shaped frame is slidably mounted inside the U-shaped frame. A geared motor is mounted on the Z-shaped frame, and the output end of the geared motor passes through the Z-shaped frame and is fitted with a connecting sleeve. A nut sleeve is slidably mounted inside the connecting sleeve, and the nut sleeve is located above the connecting nut.

[0010] Preferably, an adjusting motor is installed above the U-shaped frame, and a lead screw is installed at the output end of the adjusting motor. The lead screw is rotatably installed inside the U-shaped frame, and a Z-shaped frame is threaded onto the lead screw. A vertical guide rod is installed on the inner wall of the U-shaped frame, and the vertical guide rod is slidably installed inside the Z-shaped frame. A control module is installed on one side of the slide table, and the control module is electrically connected to the reduction motor and the adjusting motor.

[0011] Preferably, the slide has two symmetrical guide grooves, and two pulleys are rotatably installed on both sides of the slide, with the pulleys movably installed in the corresponding guide grooves.

[0012] Preferably, the inner wall of the connecting sleeve is provided with a plurality of sliding grooves, and a slider is slidably installed in the sliding grooves. The slider is installed on the surface of the nut sleeve, and a spring is installed on one side of the nut sleeve. One end of the spring is installed on the inner wall of the connecting sleeve.

[0013] Preferably, the positioning structure includes a fixed shaft mounted on a connecting frame, which is mounted on one side of the slide. An L-shaped positioning plate is rotatably sleeved on the fixed shaft, corresponding to a nut sleeve. Several positioning grooves are provided on the mold edge strip, which are adapted to the L-shaped positioning plate and correspond to positioning screws. A switch is installed on the connecting frame, corresponding to the L-shaped positioning plate. An indicator light is installed on one side of the slide, and both the indicator light and the switch are electrically connected to the control module. One end of a torsion spring is mounted on the fixed shaft, and the other end of the torsion spring is mounted on the inner wall of the L-shaped positioning plate.

[0014] Preferably, two plug-in seats are symmetrically installed on one side of the connecting frame, and the same limiting rod is inserted inside the two plug-in seats, with the limiting rod in contact with the L-shaped positioning plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) In this invention, when the mold cover plate and the pipe pile mold are combined, the positioning screw will pass through the insertion hole and the L-shaped stop bar will pass through the slot. At this time, the connecting nut can be put on the positioning screw and tightened. During the tightening of the connecting nut, the umbrella-shaped pressure ring will squeeze the L-shaped stop bars on both sides, so that the L-shaped stop bar slides in the slot and protects the top side of the mold side strip 2, which strengthens the connection between the pipe pile mold and the mold cover plate, further locks the relative position of the cover plate and the mold, and prevents the connection from loosening.

[0016] (2) In this invention, the nut sleeve can be moved above the connecting nut by pushing the slide table. When the nut sleeve is aligned with the connecting nut, the nut sleeve can be lowered by turning on the adjusting motor. At the same time as it is lowering, the deceleration motor is turned on to control the nut sleeve to rotate slowly. The continuously lowering nut sleeve will contact the connecting nut and squeeze the spring three. When the rotating nut sleeve drives its hexagonal groove to correspond to the shape of the connecting nut, the spring three will push the nut sleeve to be fitted onto the connecting nut. Then the continuously rotating and lowering nut sleeve can slowly screw the connecting nut onto the positioning screw, realizing the rapid installation and locking of the connecting nut. At the same time, the movement of the slide table and the lifting and lowering of the nut sleeve are faster. There is no need for the staff to repeatedly lift the tool to tighten the nut, which shortens the assembly time of a single mold. It is suitable for batch scenarios such as pipe pile production that require high frequency of nut installation and can improve production efficiency.

[0017] (3) In this invention, when the positioning screw is moved to the side of the corresponding positioning screw, the limiting insert can be pulled out. At this time, the torsion spring will drive the L-shaped positioning plate to flip. One end of the L-shaped positioning plate will contact the bottom of the mold edge strip. Then, the slide table is pushed and pulled back and forth. When the positioning groove is aligned with the L-shaped positioning plate, the torsion spring will drive the L-shaped positioning plate to be inserted into the positioning groove. At this time, the nut sleeve can be aligned with the top of the connecting nut. At the same time, the L-shaped positioning plate will trigger the switch to make the indicator light light up, reminding the staff that the nut sleeve and the connecting nut are aligned, so as to quickly align the nut sleeve and the connecting nut for assembly operation.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-8 This invention provides a technical solution: a novel locking mechanism for a pipe pile production mold, comprising a pipe pile mold 100 and a mold cover plate 101, a mold side strip 102 provided on the pipe pile mold 100, and a mold side strip 203 provided on the mold cover plate 101; characterized in that: a mold frame 104 is movably installed on the pipe pile mold 100, a plurality of positioning screws 200 are installed on the mold side strip 102, a plurality of insertion holes 201 are opened in the mold side strip 203, the positioning screws 200 are inserted into the corresponding insertion holes 201, a locking structure is connected to the positioning screws 200, a slide 300 is installed on one side of the mold frame 104, a tightening structure is connected to the slide 300, a connecting frame 400 is connected to the tightening structure, and a positioning structure is connected to the connecting frame 400.

[0022] Furthermore, the locking structure includes a connecting nut 202, which is threaded onto the positioning screw 200. A limit guide rod 203 is installed on the inner wall of the mold side strip 102. An L-shaped stop rod 204 is slidably fitted onto the limit guide rod 203, and the L-shaped stop rod 204 has an inclined surface. Several slots 205 are formed on the mold side strip 203, corresponding to the L-shaped stop rod 204. An umbrella-shaped pressure ring 206 is installed on one side of the connecting nut 202, located above the inclined surface of the L-shaped stop rod 204. A spring 207 is movably fitted onto the positioning screw 200, with both ends of the spring 207 contacting the umbrella-shaped pressure ring 206 and the mold side strip 203 respectively. A spring 208 is slidably fitted onto the limit guide rod 203. One end is installed on the inner wall of the mold side strip 102, and the other end of the spring 208 is installed on one side of the L-shaped stop bar 204. The mold frame 104 can be used to support the pipe pile mold 100. During the process of merging the mold cover plate 101, the positioning screw 200 will pass through the insertion hole 201, and the L-shaped stop bar 204 will pass through the slot 205. When the connecting nut 202 is screwed on the positioning screw 200, it will drive the umbrella-shaped pressure ring 206 to contact the inclined surface of the L-shaped stop bar 204. At this time, the umbrella-shaped pressure ring 206 will continue to move and squeeze the L-shaped stop bar 204 to make it slide on the limit guide rod 203. The continuously moving L-shaped stop bar 204 will protect the mold side strip 103 above, and with the tightening of the connecting nut 202, the connection between the mold cover plate 101 and the pipe pile mold 100 can be strengthened.

[0023] Example 2: Figure 1-7To facilitate the tightening of the connecting nut 202, a tightening structure is provided. This structure includes a slide table 301, movably mounted above the slide frame 300. A U-shaped frame 314 is mounted above the slide table 301. A Z-shaped frame 302 is slidably mounted inside the U-shaped frame 314. A reduction motor 303 is mounted on the Z-shaped frame 302. The output end of the reduction motor 303 passes through the Z-shaped frame 302 and is fitted with a connecting sleeve 304. A nut sleeve 305 is slidably mounted inside the connecting sleeve 304, positioned above the connecting nut 202. An adjusting motor 306 is mounted above the U-shaped frame 314. A lead screw 307 is mounted at the output end of the adjusting motor 306 and rotatably mounted inside the U-shaped frame 314. The Z-shaped frame 302 is threaded onto the lead screw 307. A vertical guide rod 308 is mounted on the inner wall of the U-shaped frame 314. The rod 308 is slidably installed inside the Z-shaped frame 302. A control module 309 is installed on one side of the slide table 301. The control module 309 is electrically connected to the geared motor 303 and the adjusting motor 306. Two guide grooves 310 are symmetrically opened on the slide 300. Two pulleys 311 are rotatably installed on both sides of the slide table 301. The pulleys 311 are movably installed in the corresponding guide grooves 310. Turning on the adjusting motor 306 can control the lead screw 307 to rotate. The lead screw 307 can drive the Z-shaped frame 302 to slide on the vertical guide rod 308, thereby controlling the geared motor 303 to descend. While descending, the geared motor 303 can be turned on to drive the connecting sleeve 304 and the nut sleeve 305 to rotate slowly. The continuously descending nut sleeve 305 will be fitted onto the connecting nut 202. Subsequently, the continuous rotation and descent of the nut sleeve 305 can slowly screw the connecting nut 202 onto the positioning screw 200.

[0024] Furthermore, the inner wall of the connecting sleeve 304 is provided with several sliding grooves 312, and a slider 313 is slidably installed in the sliding grooves 312. The slider 313 is installed on the surface of the nut sleeve 305. A spring 315 is installed on one side of the nut sleeve 305, and one end of the spring 315 is installed on the inner wall of the connecting sleeve 304. When the connecting sleeve 304 rotates, it will drive the nut sleeve 305 to rotate through the cooperation of the sliding grooves 312 and the slider 313. The continuously descending nut sleeve 305 will be compressed, causing the slider 313 to slide in the sliding grooves 312 and compress the spring 315. When the rotating nut sleeve 305 drives its hexagonal groove to correspond to the shape of the connecting nut 202, the contracted spring 315 will push the nut sleeve 305 to be fitted onto the connecting nut 202.

[0025] Example 3: As Figure 1-8To quickly align the nut sleeve 305 with the connecting nut 202, a positioning structure is provided. This structure includes a fixed shaft 401 mounted on a connecting frame 400, which is mounted on one side of a slide table 301. An L-shaped positioning plate 402 is rotatably mounted on the fixed shaft 401, corresponding to the nut sleeve 305. Several positioning grooves 403 are formed on the mold edge strip 102, each matching the L-shaped positioning plate 402 and corresponding to the positioning screw 200. A switch 404 is mounted on the connecting frame 400, corresponding to the L-shaped positioning plate 402. An indicator light 405 is mounted on one side of the slide table 301, and both the indicator light 405 and the switch 404 are electrically connected to the control module 309. One end of a torsion spring 408 is mounted on the fixed shaft 401, and the other end of the torsion spring 408 is mounted inside the L-shaped positioning plate 402. On the wall, two plug-in seats 406 are symmetrically installed on one side of the connecting frame 400. The same limiting rod 407 is inserted inside the two plug-in seats 406. The limiting rod 407 contacts the L-shaped positioning plate 402. When the limiting rod 407 is pulled out from the plug-in seat 406, the retracted fixed shaft 401 will be released and drive the L-shaped positioning plate 402 to flip on the fixed shaft 401. During the movement of the slide table 301, the connecting frame 400 and the L-shaped positioning plate 402 will be moved. When the L-shaped positioning plate 402 is aligned with the positioning groove 403, the L-shaped positioning plate 402 will be driven into the positioning groove 403 under the action of the torsion spring 408, so that the nut sleeve 305 is aligned with the top of the connecting nut 202. The other end of the L-shaped positioning plate 402 will press the trigger switch 404, and the control indicator light 405 will light up to remind the staff that the nut sleeve 305 and the connecting nut 202 are aligned.

[0026] The working principle is as follows: the pipe pile mold 100 can be hoisted onto the mold frame 104 for support. During the process of merging the mold cover plate 101, the positioning screw 200 will pass through the insertion hole 201, while the L-shaped stop bar 204 will pass through the slot 205, forming a... Figure 2In this state, the operator can then push the slide 301 to drive the pulley 311 to roll within the guide groove 310, making the slide 301 move more smoothly. Simultaneously, the spring 207 can be fitted onto the corresponding positioning screw 200, and a connecting nut 202 can be fitted onto the positioning screw 200. The moving slide 301 can then move the connecting sleeve 304 above the corresponding positioning screw 200. Then, the limiting rod 407 is pulled out of the insertion seat 406. Here, the fixed shaft 401 is in a retracted, energy-storing state. Pulling out the limiting rod 407 will cause it to disengage from the L-shaped positioning plate 402. At this time, the retracted fixed shaft 401 will release and cause the L-shaped positioning plate 402 to flip on the fixed shaft 401, so that one end of the L-shaped positioning plate 402 contacts the bottom of the mold edge strip 102. During the movement of the slide table 301, the connecting frame 400 and the L-shaped positioning plate 402 will move. When the L-shaped positioning plate 402 is aligned with the positioning groove 403, the L-shaped positioning plate 402 will be driven into the positioning groove 403 by the torsion spring 408. Since the positioning groove 403 is located directly below the positioning screw 200 and the L-shaped positioning plate 402 is located directly below the nut sleeve 305, when the L-shaped positioning plate 402 is driven into the positioning groove 403, the nut sleeve 305 can be aligned with the top of the connecting nut 202, while restricting the movement of the slide table 301. The other end of the L-shaped positioning plate 402 will press the trigger switch 404, causing the switch 404 to transmit a signal to the control module 309, and the control indicator light 405 will light up, reminding the operator that the nut sleeve 305 and the connecting nut 202 are aligned. Subsequently, the control module 309 activates the adjusting motor 306, which controls the rotation of the lead screw 307. The lead screw 307, through its threaded engagement with the Z-shaped frame 302, drives the Z-shaped frame 302 to slide on the vertical guide rod 308, thereby controlling the reduction motor 303 to descend. Simultaneously, the control module 309 activates the reduction motor 303 to drive the connecting sleeve 304 to rotate slowly. The connecting sleeve 304, through the engagement of the sliding groove 312 and the slider 313, drives the nut sleeve 305 to rotate. The continuously descending nut sleeve 305 will then engage with the connecting... When nut 202 contacts, the continuously descending nut sleeve 305 is compressed, causing slider 313 to slide within groove 312 and compress spring 315. When the rotating nut sleeve 305 aligns its hexagonal groove with the shape of connecting nut 202, the compressed spring 315 pushes the nut sleeve 305 onto the connecting nut 202. The continued rotation and descent of the nut sleeve 305 then slowly screws the connecting nut 202 onto the positioning screw 200. Both the connecting sleeve 304 and the nut sleeve 305 have internal openings for positioning... The matching hole of the screw 200 allows the positioning screw 200 to pass through the hole when the nut sleeve 305 and the connecting sleeve 304 descend. When the connecting nut 202 is screwed onto the positioning screw 200, it will move towards the mold edge strip 102. The connecting nut 202 will drive the umbrella-shaped pressure ring 206 to contact the inclined surface of the L-shaped stop rod 204. At this time, the continuous movement of the umbrella-shaped pressure ring 206 will squeeze the L-shaped stop rod 204 to make it slide on the limit guide rod 203. At the same time, the L-shaped stop rod 204 will compress the spring 208. After that, the continuously moving L... The L-shaped stop bar 204 will protect the mold edge strip 103 above, and together with the tightening of the connecting nut 202, it can strengthen the connection between the mold cover plate 101 and the pipe pile mold 100, and improve its stability. During the subsequent disassembly and unscrewing of the connecting nut 202, the spring 207 will help push the connecting nut 202 to rise and get away from the positioning screw 200, and at the same time drive the umbrella-shaped pressure ring 206 to get away from the compression of the L-shaped stop bar 204. At this time, the spring 208 will push the L-shaped stop bar 204 to move and reset, making it convenient to open the mold cover plate 101.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
