[0028] The following will be combined with the drawings in the embodiments of this application / this application to clearly and completely describe the technical solutions in the embodiments of this application / this application. Obviously, the described embodiments are only part of the embodiments of this application / this application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the application / this application and its application or use. Embodiment 1
[0029] This embodiment provides a pipe connection clamp to solve the problem in the prior art that the clamping force of the hose clamp is too small and cannot adapt to large-diameter pipes.
[0030] refer to Figures 1 to 5 The pipe connection clamp provided in this embodiment includes:
[0031] A steel band type elastic hose clamp 1, comprising a clamp head 1.1 for adjusting the clamping force;
[0032] The elastic compensation sheet 2 includes a support section 2.1 and a tortuous elastic section 2.2 located on both sides of the support section 2.1; the steel belt type elastic hose clamp 1 is semi-enclosed and inserted into the elastic compensation sheet 2, the support section 2.1 is force-transmittingly connected to the outer side surface of the steel belt type elastic hose clamp 1 away from the clamp head 1.1, and buckles 2.3 are arranged at the ends of both sides of the elastic compensation sheet 2, and the buckles 2.3 are force-transmittingly connected to the clamp head 1.1.
[0033] When using, Figure 3 The two middle hoops 1.1 are pressed toward the middle, and the steel belt type elastic hose clamp 1 and the elastic compensation sheet 2 are elastically deformed so that the internal space diameter of the steel belt type elastic hose clamp 1 reaches the outer diameter of the pipe; the steel belt type elastic hose clamp 1 is put on the outside of the pipe connection port, and then the hoops 1.1 are loosened; under the elastic force of the steel belt type elastic hose clamp 1 and the elastic force of the elastic compensation sheet 2, the inside of the steel belt type elastic hose clamp 1 is tightened to clamp the pipe connection port.
[0034] The traditional steel-belt elastic hose clamp uses cold-rolled spring steel with a hardness between 510HV-580HV, resulting in a maximum unidirectional clamping force of about 300N, which is generally used for the connection of small-diameter pipes with lower internal pressure. Compared with the traditional steel-belt elastic hose clamp, the present embodiment introduces an elastic compensation sheet 2 acting on the clamp head 1.1 to provide a greater preload force, and the material of the elastic compensation sheet 2 can be flexibly adjusted to compensate for different clamping forces according to different needs. In the liquid pipeline system of the excavator, the pipe diameter exceeds 30mm, and the traditional steel-belt elastic hose clamp cannot clamp the liquid pipeline of the excavator. The pipeline connection clamp provided in this embodiment improves the clamping force of the steel-belt elastic hose clamp 1 on the hydraulic pipeline through the elastic compensation sheet 2, which can meet the connection requirements of the liquid pipeline of the excavator.
[0035] At the same time, observe Figure 2 and Figure 3 It is not difficult to see that the steel belt type elastic hose clamp 1 is semi-enclosed and inserted into the elastic compensation plate 2. At the two clamp heads 1.1 of the steel belt type elastic hose clamp 1, the clamp head 1.1 and the buckle 2.3 form a force transmission connection point. The outer side of the steel belt type elastic hose clamp 1 away from the clamp head 1.1 is force-transmittedly connected to the support section 2.1. The formed force structure can ensure that under large clamping force conditions, the steel belt type elastic hose clamp 1 and the elastic compensation plate 2 can maintain a stable connection relationship. Embodiment 2
[0036] This embodiment provides a pipe connecting clamp. This embodiment is optimized on the basis of the first embodiment to improve the technical effect and refine the technical solution. For the contents not fully described in this embodiment, please refer to the first embodiment.
[0037] refer to Figure 2 Optionally, in a further but non-limiting embodiment of the present application, the steel band type elastic hose clamp 1 has at least one weight reduction hole 1.2. The weight reduction hole 1.2 reduces the amount of material used, directly reducing the production cost. The design of the weight reduction hole helps to improve the stress distribution of the clamp in the working state, avoid local stress concentration, and thus improve its bearing capacity and service life.
[0038] As one embodiment, the steel band type elastic hose clamp 1 is provided with a plurality of weight-reducing holes 1.2, the weight-reducing holes 1.2 are isosceles triangles, and the triangle bases of at least one pair of weight-reducing holes 1.2 are located correspondingly and in parallel.
[0039] refer to Figure 1The elastic compensation sheet 2 further comprises a pair of limit slots 2.4 arranged along the width direction of the support section 2.1. The distance between the two limit slots 2.4 matches the width of the steel belt type elastic hose clamp 1. The steel belt type elastic hose clamp 1 is inserted into the limit slots 2.4 to realize the assembled force transmission connection with the elastic compensation sheet 2. The assembly effect is as follows: Figure 2 and Figure 3 This connection method is simple to install. When in use, the steel belt type elastic hose clamp 1 is first independently put on the pipeline, and then the elastic compensation sheet 2 is inserted and assembled along the position of the limit groove 2.4 and the corresponding relationship between the clamp head 1.1 and the buckle 2.3, which reduces the difficulty of the installation process.
[0040] In addition to the assembled connection, as one embodiment, the inner side of the support section 2.1 is welded to the outer side of the steel band type elastic hose clamp 1, and the welding connection method ensures the stability of the connection between the steel band type elastic hose clamp 1 and the elastic compensation plate 2.
[0041] When in use, the clamping force compensated by the elastic compensation sheet 2 is transmitted between the hoop head 1.1 and the buckle 2.3, and the buckle 2.3 will bear the large pulling force of the hoop head 1.1, refer to Figure 2 , Figure 3 and Figure 5 The buckle 2.3 extends toward the root of the hoop head 1.1 to form a chamfered structure to prevent the hoop head 1.1 from coming out. The buckle 2.3 increases the force bearing area between the hoop head 1.1 through the chamfered structure and forms a self-locking structure to prevent the hoop head 1.1 from coming out.
[0042] refer to Figure 3 and Figure 4 The tortuous elastic section 2.2 includes a plurality of continuously connected right-angle bends 2.2.2 with circular arc transitions. Compared with the straight elastic section, the right-angle bends 2.2.2 with circular arc transitions can improve the deformation capacity and compensation range of the elastic compensation sheet 2.
[0043] Optionally, in a further but non-limiting embodiment of the present application, the support section 2.1 is a inferior arc belt structure, and the area of the support section 2.1 and the outer side surface of the steel belt type elastic hose clamp 1 for force transmission becomes larger to adapt to the increase of the clamping force.
[0044] refer to Figure 2 In the dotted circle, when the diameter of the pipe inside the steel belt type elastic hose clamp 1 is large, the clamp heads 1.1 are close to each other, which will cause the edge of the inferior arc band structure to fit with the outer side of the steel belt type elastic hose clamp 1, thereby increasing the clamping force compensation of the elastic compensation plate 2 and realizing adaptive adjustment.
[0045] In addition, there is also an adaptive adjustment mechanism between the hoop head 1.1 and the buckle 2.3.
[0046] As one of the embodiments, the elastic compensation sheet 2 is made in one piece to prevent breakage.
[0047] Optionally, the design standard of the steel band type elastic hose clamp 1 may refer to QC / T 621.1-621.3.
[0048] In summary, the pipe connecting clamp provided in this embodiment improves the technical effect and refines the technical solution compared with the first embodiment.
