Description

Technical Field

[0001] This utility model relates to the field of spring clamp installation technology, and more specifically, to a connecting tooling for spring clamps. Background Technology

[0002] In industrial production and daily pipeline laying, spring clamps are widely used in the rapid connection of various pipelines such as water pipes and air pipes due to their simple structure, reliable connection, and reusability. They are key components for ensuring the sealing and stability of pipeline systems. Spring clamps are circular structures formed by stamping spring steel in one piece. They mainly consist of a clamp ring, from which two lugs extend, namely a large lug and a small lug.

[0003] Currently, the installation of spring clamps largely relies on manual assembly. Operators must manually press the large and small lugs of the spring clamp, applying external force to open the clamp ring, then slip it onto the pipe fitting or connector to be connected. Releasing the external force allows the clamp to return to its original elasticity and achieve a secure clamping effect. However, for larger or more elastic spring clamps, the manual opening process requires significant physical strength, increasing the operator's workload and potentially leading to insufficient opening and affecting pipe insertion efficiency. Furthermore, the lugs are prone to slippage during the pressing process due to unstable force, posing a safety hazard. In addition, prolonged repetitive operations can easily lead to operator fatigue, further reducing installation efficiency and failing to meet the demands of large-scale production for efficient assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a connecting tool for spring clamps, which solves the problems of laborious installation, low efficiency and easy slippage of existing spring clamps.

[0005] This utility model is achieved through the following technical solution: a connecting fixture for a spring clamp, including a box body, a sliding groove, a first limiting block and a second limiting block respectively arranged in the sliding groove, a linear actuator for driving the first limiting block to slide in the sliding groove at the top of the box body, a mounting groove for the second limiting block, a lever mechanism arranged in the mounting groove, the middle part of the lever mechanism being hinged to the second limiting block, a first connecting rod and a second connecting rod respectively arranged at both ends of the lever mechanism, the first limiting block abutting against the upper end lug of the spring clamp, and the first limiting block abutting against the first connecting rod for prying the second connecting rod to push the lower end lug of the spring clamp to open the spring clamp.

[0006] Furthermore, the end of the second limiting block near the first limiting block is provided with an inclined concave surface that abuts against the lower end support lug of the spring clamp, and the inclined concave surface is connected to the edge of the groove of the mounting groove.

[0007] Furthermore, the lever mechanism includes a lever and a base fixed to the bottom of the mounting groove. The base is hinged to the middle of the lever, and the two ends of the lever are respectively hinged to a first connecting rod and a second connecting rod. An auxiliary rod arranged parallel to the lever is hinged between the first connecting rod and the second connecting rod.

[0008] Furthermore, the end of the second connecting rod is hinged with a pusher seat that engages with the spring clamp lug.

[0009] Furthermore, it includes a bracket, which is L-shaped and includes a horizontal section and an inclined section. The box body is fixed to the inclined section so that the end face of the box body with the groove is inclined upward.

[0010] Furthermore, the first limiting block has a connecting groove, and a stop rod is movably connected in the connecting groove. An elastic element is provided between the stop rod and the first limiting block.

[0011] Furthermore, the spring clamp includes a small lug, a large lug, and a hoop. The small lug abuts against the first limiting block, and the large lug abuts against the second limiting block. The second limiting block has a relief groove for avoiding the connection between the small lug and the hoop.

[0012] This utility model has at least the following advantages and beneficial effects: by setting a first limiting block and a second limiting block in the groove opened in the box body, combined with the lever mechanism, the mechanical opening of the spring clamp is realized, which reduces the labor intensity of the operator, improves the efficiency of pipe insertion, and eliminates the risk of hand injury caused by the slippage of the support lug during manual operation.

Detailed Implementation

[0019] The specific implementation method is described below with reference to the accompanying drawings.

[0020] Example like Figures 1 to 5 As shown, this embodiment mainly discloses a connecting fixture for a spring clamp 1, including a box body 2. The box body 2 has a sliding groove 20. A first limiting block 3 and a second limiting block 4 are respectively arranged in the sliding groove 20. A linear actuator 5 for driving the first limiting block 3 to slide in the sliding groove 20 is provided at the top of the box body 2. The second limiting block 4 has an installation groove 40. A lever mechanism 6 is provided in the installation groove 40. The middle part of the lever mechanism 6 is hinged to the second limiting block 4. A first connecting rod 61 and a second connecting rod 62 are respectively arranged at both ends of the lever mechanism 6. The first limiting block 3 abuts against the upper end lug of the spring clamp 1, and the first limiting block 3 abuts against the first connecting rod 61 to pry the second connecting rod 62 to push the lower end lug of the spring clamp 1 to open the spring clamp 1. Specifically, the linear actuator 5 provides power and can be a linear cylinder, linear hydraulic cylinder, or linear electric cylinder; the first limit block 3 directly abuts against the upper end lug of the spring clamp 1, and at the same time, the lever mechanism 6 links the second connecting rod 62 to push the lower end lug, replacing the manual squeezing operation and solving the problems of laborious and inefficient manual operation; it should be noted that the lever mechanism 6 is designed as a force-saving lever (the lever arm length from the fulcrum to the first connecting rod 61 is greater than the lever arm length from the fulcrum to the second connecting rod 62), which can amplify the force, especially suitable for clamps with larger size or stronger elasticity, and improve the applicability of the tooling.

[0021] Furthermore, in a specific implementation, the second limiting block 4 provided in this embodiment of the present invention has an inclined concave surface 41 at its end near the first limiting block 3, which abuts against the lower end lug of the spring clamp 1. The inclined concave surface 41 is connected to the edge of the groove of the mounting groove 40. This achieves precise positioning of the lower end lug of the spring clamp 1. The inclined concave surface 41 can adapt to the shape of the lug, preventing the lug from slipping during the force application process and improving the stability of the spring clamp 1 when it opens. The structural design of being connected to the groove of the mounting groove 40 ensures that the force transmission path is continuous when the lever mechanism 6 pushes the lug.

[0022] Furthermore, in a specific implementation, the lever mechanism 6 provided in this embodiment of the present invention includes a lever and a base 63 fixed to the bottom of the mounting groove 40. The base 63 is hinged to the middle of the lever, and both ends of the lever are hinged to the first connecting rod 61 and the second connecting rod 62, respectively. An auxiliary rod 64, arranged parallel to the lever, is hinged between the first connecting rod 61 and the second connecting rod 62. Specifically, the hinge of the base 63 fixes the lever fulcrum, ensuring stable force transmission; the auxiliary rod 64 ensures the parallelism and stability of the first connecting rod 61 and the second connecting rod 62, enhances the overall rigidity of the lever mechanism 6, avoids the decrease in action accuracy caused by deformation under force during long-term use, extends the service life of the tooling, and improves the stability of the clamp opening process.

[0023] Furthermore, in a specific implementation, the end of the second connecting rod 62 provided in this embodiment of the present invention is hinged with a pusher seat 65 that engages with the lug of the spring clamp 1. The pusher seat 65 can increase the contact area with the lug, avoiding excessive local stress and deformation damage to the lug caused by direct pushing of the end of the second connecting rod 62; the hinged structure can adapt to the angle change of the lug during the opening process, ensuring that the contact is always close, improving the stability of the pushing operation and the protection of the lug.

[0024] Furthermore, in a specific implementation, the above-mentioned embodiment of this utility model includes a bracket 7, which is L-shaped and includes a horizontal section 71 and an inclined section 72. The box body 2 is fixed to the inclined section 72 so that the end face of the box body 2 with the sliding groove 20 is inclined upward. Specifically, the horizontal section 71 is installed on a stable table by bolts. The box body 2 is fixed by the inclined section 72 of the L-shaped bracket 7, so that the surface of the sliding groove 20 is "inclined upward facing the operator". The operator can easily pick up and put down the spring clamp 1 and observe the assembly process without bending over or adjusting posture, reducing operator fatigue and improving assembly efficiency and operational safety.

[0025] Furthermore, in a specific implementation, the first limiting block 3 provided in this embodiment of the utility model has a connecting groove 30, and a stop rod 31 is movably connected in the connecting groove 30. An elastic element 32 is provided between the stop rod 31 and the first limiting block 3. This achieves flexible contact with the lug of the spring clamp 1. The two ends of the elastic element 32 (such as a spring) are fixed to the first limiting block 3 and the stop rod 31 respectively, which can buffer the impact force of the linear actuator 5 and avoid deformation or damage to the lug caused by rigid contact; the movable connection of the stop rod 31 can adapt to slight deviations in the position of the lug, ensuring that the contact is always reliable and improving the compatibility of the tooling with clamps of different specifications.

[0026] Furthermore, in a specific implementation, the spring clamp 1 provided in this embodiment of the present invention includes a small lug 12, a large lug 13, and a hoop 11. The small lug 12 abuts against the first limiting block 3, and the large lug 13 abuts against the second limiting block 4. The second limiting block 4 has a relief groove 42 for avoiding the connection between the small lug 12 and the hoop 11. Specifically, the spring clamp 1 is prior art. The width of the large lug 13 is the same as the width of the hoop 11. The large lug 13 and the connection between the large lug 13 and the hoop 11 have through holes for the small lug 12 and the connection between the small lug 12 and the hoop 11 to pass through. The connection between the large lug 13 and the hoop 11 and the connection between the small lug 12 and the hoop 11 coincide at the position of the through hole. The clearance groove 42 can prevent the connecting part of the small ear 12 from interfering with the second limiting block 4, ensuring that when the spring clamp 1 is inserted, the connecting part of the small ear 12 and the clamp ring 11 can smoothly avoid interference with the second limiting block 4 through the clearance groove 42, thereby improving the positioning accuracy.
