Description

Technical Field

[0001] This utility model relates to the field of hydraulic lock technology, and in particular to a pneumatic anti-collision hydraulic lock. Background Technology

[0002] Pneumatic-hydraulic locks are not independent pneumatic devices, but rather locking devices based on hydraulic principles and combined with pneumatic control or applications; they are widely used in engineering machinery, vehicle equipment, and industrial automation.

[0003] Specifically, Chinese patent application number 202022775098.1 describes a hydraulic lock assembly. This patent includes a panel with a first and second rotating shaft fixedly mounted on its side. A main locking block and a first torsion spring are sleeved on the outer side of the first rotating shaft, and a locking block and a second torsion spring are sleeved on the outer side of the second rotating shaft. A first and second positioning pins are fixedly mounted on the side of the panel. A hydraulic mechanism is detachably mounted on the side of the panel. A protective plate, a bushing, and a switch assembly are also fixedly mounted on the side of the panel. In this design, the push rod pushes the locking block to rotate on the second rotating shaft, causing the main locking block to rotate on the first rotating shaft, thus achieving the locking function. The switch assembly transmits the locking signal of the mechanical structure to the cockpit, reducing the device's failure rate. The hydraulic mechanism is secured with bolts, ensuring structural stability and facilitating disassembly and maintenance, thus reducing maintenance costs. The protective plate absorbs leaked oil, preventing oil contamination and extending the device's service life.

[0004] In the aforementioned patent, the technical structure is implemented by using a hydraulic component to push a push rod, which in turn presses against the locking block. The locking block rotates counterclockwise on the second rotating shaft, thereby pressing against the bottom end of the main locking block. The main locking block rotates clockwise on the first rotating shaft to achieve the locking function. However, it has the following shortcomings: when the main locking block is locked, the force is transmitted to the locking component. Under long-term stress and when collision occurs, the locking component is too complex, easily damaged, and difficult to repair. Therefore, we propose a pneumatic anti-collision hydraulic lock. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies by designing a suitable locking structure based on a hydraulic mechanism. This structure simplifies the locking components, improves stability, and provides anti-collision functionality to prevent damage to the locking components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pneumatic anti-collision hydraulic lock includes a lock body and a hydraulic mechanism. One long side of the lock body has a locking cavity. The hydraulic mechanism is installed inside the lock body away from the locking cavity, with its output end facing the locking cavity. A connecting rod is mounted on the output end of the hydraulic mechanism. A guide frame is parallel above the hydraulic mechanism. The other end of the connecting rod is connected to a movable component slidably connected within the guide frame. The movable component extends to the outlet of the locking cavity and has a locking rod. The hydraulic mechanism extends and retracts, causing the movable component to move, thus closing / opening the locking rod against the locking cavity. After the locking rod closes against the locking cavity, one end has a pressing and anti-sway structure. Several anti-collision guide wheels are provided between the locking rod and the lock body on both sides of the locking cavity.

[0008] Furthermore, one end of the connecting rod is movably connected to the cylinder push rod of the hydraulic mechanism, and the other end is movably connected to the moving part.

[0009] Furthermore, the moving component includes a lateral moving component and a vertical moving component. The vertical moving component is vertically installed at the top of the lateral moving component away from the connecting rod end, and guide rails are provided on both sides of the lateral moving component.

[0010] Furthermore, the guide frame is designed with an opening towards the connecting rod end, and from top to bottom, it is provided with a moving part guide groove and a connecting rod clearance groove. The two sides of the moving part guide groove are provided with guide rail grooves that are adapted to guide rails.

[0011] Furthermore, a locking rod passage groove is provided at the outlet of the locking cavity, which is connected to the inside of the lock body.

[0012] Furthermore, the locking rod has wheel grooves on both the upper and lower sides, and the bottom of the locking rod has several arc-shaped force grooves corresponding to the pressing and anti-sway structure. The end of the locking rod is a semi-circular structure.

[0013] Furthermore, the clamping anti-sway structure includes a mounting base, which is bolted into the lock body. One end of the mounting base is open and a telescopic guide sleeve is provided for each arc-shaped force groove. The telescopic guide sleeve consists of a sleeve and a telescopic rod slidably connected inside the sleeve. The telescopic rod extends out of the sleeve and is provided with an arc-shaped pressure block at the end facing the arc-shaped force groove. A spring is sleeved on the periphery of the telescopic guide sleeve between the arc-shaped pressure block and the sleeve mounting surface. The spring naturally opens and drives the arc-shaped pressure block to extend into the locking rod passage groove. The locking rod abuts against the arc-shaped pressure block, causing the spring to compress. After the locking rod is fully inserted into the locking rod passage groove, the spring resets and drives the arc-shaped pressure block to abut against the arc-shaped force groove.

[0014] Furthermore, the anti-collision guide wheels are installed on both sides of the locking rod through groove, and the anti-collision guide wheels abut against the locking rod through groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Simplified locking components and improved stability: A connecting rod is installed at the output end of the hydraulic mechanism. The connecting rod is connected to a moving part that is slidably connected within the guide frame. The moving part extends to the outlet of the locking cavity and is equipped with a locking rod. The hydraulic mechanism extends and retracts to move the moving part, causing the locking rod to close / open the locking cavity. Simultaneously, the moving part includes horizontal and vertical moving components. The guide frame is equipped with a guide groove for the moving part and a clearance groove for the connecting rod, which are adapted to the guide slide of the moving part. This design makes the movement between the components more precise and smooth, reducing jamming and wear during movement, and further improving the performance and stability of the device. This utility model simplifies the locking components based on the hydraulic mechanism design and adapted locking structure. Compared with the overly complex locking components in the prior art, which are prone to damage and difficult to repair under long-term stress and impact, the simplified structure of this utility model reduces the points of failure, improves overall stability, reduces the risk of damage, and thus reduces the frequency and difficulty of maintenance.

[0017] 2. Anti-collision function: Several anti-collision guide wheels are set between the lock body and the locking rod on both sides of the locking cavity. The anti-collision guide wheels are installed on both sides of the locking rod through groove and abut against the locking rod through groove. When impacted, the anti-collision guide wheels can play a buffering and guiding role, avoiding the locking rod from being directly damaged by rigid impact, effectively protecting the locking components and extending the service life of the device.

[0018] After the locking rod closes with the locking cavity, one end is equipped with a pressing and anti-shaking structure. The spring naturally opens, causing the arc-shaped pressure block to extend into the locking rod passage groove. The locking rod abuts against the arc-shaped pressure block, compressing the spring. After full insertion, the spring returns to its original position, causing the arc-shaped pressure block to abut against the arc-shaped force groove. This design ensures that the locking rod is effectively pressed after closing, preventing shaking, ensuring the firmness and stability of the lock, and improving the reliability of the device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Example 1:

[0037] like Figure 1-5 As shown, this utility model provides a technical solution: a pneumatic anti-collision hydraulic lock, including a lock body 1 and a hydraulic mechanism 2. One end of the long side of the lock body 1 is provided with a locking cavity 11, which is used to accommodate the component to be locked or cooperate with the locked structure to achieve the locking function. The hydraulic mechanism 2 is installed inside the lock body 1 away from the locking cavity 11. This layout can make reasonable use of the internal space of the lock body, while avoiding interference of the hydraulic mechanism 2 with the operation of the locking cavity 11. The output end of the hydraulic mechanism 2 faces the locking cavity 11 of the lock body 1. A connecting rod 3 is installed at the output end of the hydraulic mechanism 2. A guide frame 4 is provided parallel above the hydraulic mechanism 2. The other end of the connecting rod 3 is connected to a moving part 5 that is slidably connected in the guide frame 4. The moving part 5 extends to the outlet of the locking cavity 11 and is provided with a locking rod 6.

[0038] The extension and retraction of the hydraulic mechanism 2 drives the connecting rod 3 to move, which in turn causes the moving part 5 to slide within the guide frame 4, ultimately realizing the closing or opening operation of the locking rod 6 against the locking cavity 11. After the locking rod 6 closes against the locking cavity 11, one end is provided with a pressing and anti-sway structure 7. This structure can ensure that the locking rod 6 is firm and stable in the closed state and prevent shaking. Several anti-collision guide wheels 8 are provided between the locking body 1 on both sides of the locking cavity 11 and the locking rod 6. The anti-collision guide wheels 8 can guide the movement of the locking rod 6, and at the same time, buffer the impact force when subjected to external impact, protecting the locking rod 6 and related structures.

[0039] Example 2:

[0040] like Figure 1-5 As shown, one end of the connecting rod 3 is movably connected to the cylinder push rod of the hydraulic mechanism 2, and the other end is movably connected to the moving part 5. This movable connection allows the connecting rod 3 to move flexibly under the drive of the hydraulic mechanism 2, thereby driving the moving part 5 to make corresponding movements.

[0041] The moving part 5 includes a horizontal moving part 51 and a vertical moving part 52. The vertical moving part 52 is vertically installed at the top of the horizontal moving part 51 away from the end of the connecting rod 3. Guide slides 53 are provided on both sides of the horizontal moving part 51. The guide frame 4 is designed to open towards the end of the connecting rod 3. From top to bottom, it is provided with a moving part guide groove 41 and a connecting rod clearance groove 42. The guide slides 53 on both sides of the moving part guide groove 41 are provided with slide grooves 43. When the moving part 5 slides in the guide frame 4, the guide slides 53 move in the slide grooves 43, ensuring the linearity and stability of the moving part 5. The connecting rod clearance groove 42 provides space for the movement of the connecting rod 3 and avoids interference between the connecting rod 3 and the guide frame 4.

[0042] The locking cavity 11 outlet is connected to the inside of the lock body 1 and has a locking rod passage groove 12. The locking rod 6 enters and exits the locking cavity 11 through the passage groove 12 to realize locking and unlocking operations.

[0043] The locking rod 6 has wheel grooves 61 on both the upper and lower sides. The anti-collision guide wheel 8 can be embedded in the wheel groove 61 to better guide and protect the locking rod 6 from collision. The bottom of the locking rod 6 has several arc-shaped force grooves 62 corresponding to the pressing and anti-sway structure 7. The end of the locking rod 6 is a semi-circular structure. The semi-circular structure makes the locking rod 6 move more smoothly when entering and exiting the locking rod through the groove 12, reducing friction and jamming.

[0044] The clamping and anti-sway structure 7 includes a mounting base 71, which is bolted into the lock body 1. One end of the mounting base 71 is open and a telescopic guide sleeve 72 is provided for each arc-shaped force groove 62. The telescopic guide sleeve 72 consists of a sleeve 721 and a telescopic rod 722 slidably connected inside the sleeve 721. The telescopic rod 722 extends out of the sleeve 721 and is provided with an arc-shaped pressure block 73 at the end facing the arc-shaped force groove 62. A spring 74 is sleeved on the periphery of the telescopic guide sleeve 72 between the arc-shaped pressure block 73 and the mounting surface of the sleeve 721. The spring 74 naturally opens and drives the arc-shaped pressure block 73 to extend into the locking rod passage groove 12. When the locking rod 6 is inserted, it abuts against the arc-shaped pressure block 73, compressing the spring 74. After the locking rod 6 is fully inserted into the locking rod passage groove 12, the spring 74 returns to its original position and drives the arc-shaped pressure block 73 to abut against the arc-shaped force groove 62, thereby achieving the clamping and anti-sway effect.

[0045] The anti-collision guide wheels 8 are installed on both sides of the locking rod through groove 12, and the anti-collision guide wheels 8 abut against the locking rod through groove 12, so that the locking rod 6 can always maintain the guiding and anti-collision protection function during the movement of the locking rod 6.

[0046] The working process of this utility model is as follows: When using a pneumatic anti-collision hydraulic lock, first install the pneumatic anti-collision hydraulic lock on the equipment or structure that needs to be locked, ensure that the locking cavity 11 corresponds accurately with the position of the locked part, and that the hydraulic mechanism 2 is correctly connected to the pneumatic control system to ensure that the hydraulic mechanism 2 can work normally.

[0047] When locking is required, the pneumatic control system is activated to supply air to the hydraulic mechanism 2, causing the cylinder push rod of the hydraulic mechanism 2 to extend. The cylinder push rod pushes the connecting rod 3. Since the connecting rod 3 is movably connected to the moving part 5, the movement of the connecting rod 3 causes the moving part 5 to slide within the guide frame 4. The lateral moving part 51 of the moving part 5 moves linearly within the moving part guide groove 41 of the guide frame 4 via the guide slide 53. At the same time, the vertical moving part 52 also moves accordingly, thereby driving the locking rod 6 to move towards the locking cavity 11. During the movement of the locking rod 6, the anti-collision guide wheel 8 is embedded in the wheel groove 61 of the locking rod 6, thus preventing the locking rod from moving. The locking rod 6 is guided to ensure that it accurately enters the locking rod passage groove 12. When the locking rod 6 approaches the locking rod passage groove 12, the semi-circular structure at the end of the locking rod 6 enters the passage groove 12 first. As it continues to move, the locking rod 6 abuts against the arc-shaped pressure block 73 of the anti-sway structure 7, causing the spring 74 to compress. When the locking rod 6 is fully inserted into the locking rod passage groove 12, the spring 74 returns to its original position, causing the arc-shaped pressure block 73 to abut against the arc-shaped force groove 62 at the bottom of the locking rod 6, pressing the locking rod 6 tightly to prevent it from shaking. At this time, the locking rod 6 closes the locking cavity 11, realizing the locking function of the locked part.

[0048] When unlocking is required, the pneumatic control system is restarted to change the air supply direction, causing the cylinder push rod of the hydraulic mechanism 2 to retract. The cylinder push rod drives the moving part 5 to move in the opposite direction through the connecting rod 3, thereby causing the locking rod 6 to exit from the locking rod through slot 12, opening the locking cavity 11, and allowing the locked part to move freely, thus completing the unlocking operation. Throughout the entire working process, the anti-collision guide wheel 8 always plays a guiding and anti-collision protection role for the locking rod 6, ensuring that the pneumatic anti-collision hydraulic lock can work stably and reliably.

[0049] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
