Description

Technical Field

[0001] This utility model belongs to the field of clamping tool technology, specifically relating to a garbage cleaning clamp. Background Technology

[0002] Currently, in daily life and municipal cleaning work, garbage scattered on the ground is generally cleaned up manually. For some waste that is inconvenient to bend over to pick up or that needs to be avoided from direct hand contact, such as cigarette butts, paper scraps, and fruit peels, auxiliary tools with clamping functions are often used to pick them up.

[0003] However, existing garbage clamps generally have the following problems:

[0004] Firstly, the structure is simple, with the gripping arms mostly being two-claw structures, resulting in uneven force distribution and difficulty in stably clamping irregularly shaped or lighter waste, which easily leads to situations where the gripping is not secure or the waste slips out.

[0005] Secondly, the clamping control mechanism mostly relies on simple rope traction or single linkage transmission. The clamping actions are not synchronized, which can easily cause the clamping arm to swing or lose control of opening and closing, affecting the accuracy of operation.

[0006] Third, some products lack an effective reset mechanism or trajectory guide structure, making it difficult for the clamping device to smoothly return to its initial open state after use, thus reducing work efficiency and user comfort. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a garbage cleaning clamp that can achieve reliable clamping effect, smooth operation and timely reset, so as to improve the synchronization of clamping and the convenience of operation, thereby better meeting the functional needs of clamping tools in public environments and daily use.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A garbage collection clamp includes a connecting rod, a handle, a clamping mechanism, and a pulling mechanism, wherein:

[0010] The handle is located at the upper end of the connecting rod, and the pulling mechanism includes a crossbar on the handle and a pull rod connected to the crossbar. The pull rod slides up and down along the inside of the connecting rod.

[0011] The clamping mechanism is located at the lower end of the connecting rod and includes a positioning head, a movable head, a linkage component, and three sets of evenly arranged clamping arms. The movable head is connected to the pull rod.

[0012] The movable head is connected to the linkage component via the first link. The linkage component includes a fixed base, three second links and corresponding pin arms, and each pin arm is connected to the corresponding clamping arm.

[0013] Each gripping arm has a chuck at its lower end for clamping the target object;

[0014] The positioning head has a guide groove inside, which is used to constrain the pull rod and the movable head to slide along the axial direction of the connecting rod.

[0015] Furthermore, the three sets of clamping arms are arranged symmetrically at the bottom of the clamping mechanism, and the linkage drives each clamping arm to close inward or open outward synchronously.

[0016] Furthermore, the movable head is sleeved on the positioning post, and a spring is provided on the outside of the positioning post to push the movable head downward to reset after being pulled and released.

[0017] Furthermore, the crossbar extends laterally inside the handle and can be pulled upwards by the fingers.

[0018] Furthermore, the clamping arm has a bent structure, with the clamp located on the inner side of the end, and the clamp is made of rubber or has an anti-slip texture.

[0019] Furthermore, the fixed seat in the linkage is located at the center position, and each second link is evenly connected to it, thereby driving the corresponding pin arm to link each clamping arm.

[0020] Furthermore, the positioning head is fixed to the bottom end of the connecting rod, and the movable head slides along the guide groove inside the positioning head to stabilize the upper and lower transmission path.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention solves the problems of uneven force distribution and unstable clamping of objects caused by the common use of double-arm structures in existing clamps by setting three sets of clamping arms in a centrally symmetrical manner at the bottom of the clamping mechanism and using a linkage to drive the three sets of clamping arms to close inward or open outward simultaneously. This makes the clamping action more stable and versatile, and improves the clamping adaptability to objects of different sizes and irregular shapes.

[0023] This invention achieves automatic reset after the clamping operation is completed by setting the movable head on the positioning post and setting a compression spring on the outside of the positioning post. This avoids the cumbersome operation caused by the need for manual reset of existing garbage clamps. At the same time, it enables the clamping mechanism to quickly return to the open state after each release control, improving the efficiency of continuous operation.

[0024] This invention solves the problems of complex structure and slow pulling response of existing clamps by setting a horizontal crossbar and a vertical pull rod to form a direct and efficient transmission path. The crossbar is located inside the handle, which is convenient for finger operation and can achieve quick clamping. The structural design conforms to ergonomics and improves the control sensitivity and ease of use.

[0025] This utility model adopts a clamping arm end structure with rubber chuck and anti-slip texture, which significantly improves the friction between the clamp and the target object during clamping, avoiding slippage and damage caused by small contact area or hard materials. This allows the garbage clamp to stably clamp lightweight, soft or slippery garbage, improving the reliability and adaptability of clamping.

[0026] This invention achieves synchronous driving of three sets of clamping arms through a linkage structure consisting of a central fixed seat and three second connecting rods. This overcomes the problems of asynchronous arm transmission and easy swaying in traditional devices, making the clamping process coordinated and consistent, the clamping action smooth and powerful, and the overall structure with a unified motion trajectory, which helps to improve clamping accuracy and stability.

[0027] This utility model has a hollow positioning head at the bottom of the connecting rod, and a guide groove inside it to constrain the movement direction of the movable head. This gives the pull rod and the movable head good guiding performance during their up and down movement, avoiding jamming or clamping errors caused by the offset of the transmission components, and improving the reliability and durability of the structure.

[0042] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0043] See Figure 1-6 A garbage collection clamp includes a connecting rod 1, a handle 11, a clamping mechanism 3, and a pulling mechanism, wherein:

[0044] A handle 11 is located at the upper end of the connecting rod 1 for the operator to hold and control the device's movement. The pulling mechanism includes a crossbar 21 on the handle 11 and a pull rod 2 connected to the crossbar 21. The crossbar 21 is horizontally positioned in the middle of the handle 11 and can be pulled by the fingers, thereby driving the pull rod 2 to slide axially up and down along the hollow channel inside the connecting rod 1. The connecting rod 1 has a sliding cavity structure inside, with its inner wall sliding in cooperation with the outer surface of the pull rod 2 to ensure the guidance and stability of the pull rod 2. A movable head 32 is connected to the bottom of the pull rod 2 and is located in the middle of the clamping mechanism 3. The clamping mechanism 3 is located at the lower end of the connecting rod 1 and includes a positioning head 31, a movable head 32, a linkage 33, and three sets of clamping arms 34. The clamping arms 34 are evenly distributed at intervals on the bottom structure of the clamping mechanism 3. The movement of the movable head 32 is achieved through a linkage structure to realize the synchronous movement of the clamping arms. This structure can effectively solve the problems of asynchronous clamping action, uneven force, and easy clamping deviation in existing clamps.

[0045] See Figure 1 and Figure 6 Three sets of clamping arms 34 are arranged symmetrically at the bottom of the clamping mechanism 3. The three clamping arms 34 are connected to the three second connecting rods 332 of the linkage 33 by pin connecting arms 333. The second connecting rods 332 are evenly distributed on the fixed base 331 at 120-degree intervals, forming a symmetrical triangular linkage system. When the linkage 33 is driven upward by the movable head 32, each second connecting rod 332 drives the pin connecting arm 333 to rotate synchronously, thereby driving the three sets of clamping arms 34 to close inward in a symmetrical manner, forming a stable three-point clamping structure. Compared with the existing double-arm clamper, this device can achieve better clamping stability and adaptability to objects of different sizes and irregularities through the three-jaw cooperative clamping method, solving the problems of unstable clamping and slippage in traditional structures.

[0046] See Figure 1-5The movable head 32 is sleeved on the positioning post 322. The upper end of the positioning post 322 is fixedly connected to the bottom of the pull rod 2. The movable head 32 is connected to the first connecting rod 321 to transmit the power for vertical movement. A spring 35 is provided on the outside of the positioning post 322. The spring 35 is sleeved on the outer cylindrical surface of the positioning post 322, and its upper and lower ends respectively abut against the lower end face of the movable head 32 and the spring limit seat on the inner wall of the positioning head 31. After the operator releases the crossbar 21, the spring 35 restores its elastic deformation, pushes the positioning post 322 and the pull rod 2 upward to reset, and makes the movable head 32 fall back to the initial position. This structure, through the setting of the elastic recovery device, enables the clamping arm 34 to automatically open in the non-operational state, improves the reset efficiency of the device, and solves the problem of cumbersome manual reset operation after the existing clamps are used.

[0047] See Figure 1-2 The crossbar 21 is horizontally inserted inside the handle 11, located at the central opening of the handle 11. It is connected to the handle by a rubber limiting ring to prevent it from coming out. The two ends of the crossbar 21 have hooks or blocks to enhance the operator's finger pulling comfort and control. When the operator pulls the crossbar 21 with their fingers, the crossbar 21 drives the connected pull rod 2 to move upward along the internal cavity of the connecting rod 1. This structure completes the clamping control through natural hand movements, which is ergonomic, convenient and solves the problems of unreasonable handle control design and insensitive clamping action in existing devices.

[0048] See Figure 6 The clamping arm 34 has a bent structure in the middle. The upper section is connected to the pin arm 333 by a pin. The middle part is bent into an arc shape to enhance rigidity and clamping torque transmission. The lower end extends to provide a chuck 341. The chuck 341 is located on the inner side of the end of the clamping arm 34. The chuck 341 is made of high friction coefficient rubber material. The outer surface is provided with anti-slip protrusions or transverse textures to enhance the friction with the surface of the object being clamped and prevent the object from slipping. Through the flexible contact between the chuck 341 and the clamping arm 34, it can achieve compatible clamping of waste of various shapes and textures, improve the reliability of use, and solve the problem that traditional rigid grippers are easily damaged or slip when clamping soft or small waste.

[0049] See Figure 4-6The fixed seat 331 in the linkage 33 is located at the center of the clamping mechanism 3. It has a three-pronged structure or an equilateral triangular disk structure, and its three ends are all hinged to the second link 332. The three second links 332 are arranged at equal angles, and each second link 332 corresponds to the corresponding pin arm 333. The pin arm 333 is then connected to the upper end of the clamping arm 34 to form a lever transmission structure. When the movable head 32 moves upward, the fixed seat 331 moves upward synchronously through the first link 321, which in turn drives the three second links 332 to rotate around their respective hinge points, thereby pushing the pin arm 333 to drive the clamping arm 34 to perform an inward closing action, realizing simultaneous clamping of the three jaws. This linkage structure can effectively improve the synchronicity and consistency of the clamping action and avoid the problem of target object deviation caused by inconsistent clamping trajectories.

[0050] See Figure 1 The positioning head 31 is fixedly installed at the bottom end of the connecting rod 1, and is tightly connected to the connecting rod 1 externally. It is hollow inside and has a guide groove 311. The guide groove 311 extends along the axial direction of the connecting rod 1 and has a semi-circular or U-shaped groove structure in cross section. It slides and engages with the side of the movable head 32 internally to limit the linear movement of the movable head 32 along the axial direction. The movable head 32 is installed in the guide groove 311, which can prevent swaying or rotation during the up and down sliding process, and helps to stabilize the transmission path and ensure the consistency of the clamping action. This guide structure effectively improves the guiding performance of the device in the transmission process and solves the problems of unstable clamping arm movement and easy deviation of the mechanism in traditional clamping devices.

[0051] The working principle of this utility model is as follows:

[0052] During use, the operator holds the handle 11 located at the top of the connecting rod 1 and pulls the crossbar 21 on the inside of the handle, causing the pull rod 2 connected to the crossbar 21 to move upward along the axial direction of the connecting rod 1. The bottom of the pull rod 2 is connected to the movable head 32 inside the clamping mechanism 3. As the movable head 32 moves upward, it drives the first connecting rod 321 and the positioning post 322 fixed thereon to rise, and at the same time drives the pin arm 333 of the linkage 33 to rotate.

[0053] As the pin arm 333 rotates, the clamping arm 34 mounted on the clamping mechanism 3 rotates inward and closes, and the chuck 341 at the end of the clamping arm 34 clamps the target object. The linkage 33 plays a role in synchronous driving and trajectory limitation, making the movement of the clamping arm 34 more coordinated and stable, and avoiding deviation or loss of control during the clamping process.

[0054] When the operator releases the crossbar 21, the spring 35 located outside the positioning column 322 recovers its elasticity after compression, pushing the movable head 32 downward, which in turn drives the linkage 33 to move in the opposite direction, causing the clamping arm 34 to reopen, preparing for the next clamping operation. The guide groove 311 is located inside the positioning head 31 to constrain the up-and-down movement trajectory of the pull rod 2 and the movable head 32, ensuring smooth and reliable operation of the entire mechanism.

[0055] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
