Description

Technical Field

[0001] The utility model relates to the technical field of metal bushings, in particular to a straight bushing that is easy to install. Background Art

[0002] A straight bushing is a positioning element used in mechanical equipment, usually to achieve a guiding function. The use of the bushing can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of the equipment. Existing bushings cannot be opened or closed, which makes installation very inconvenient, causing workers to waste a lot of time during the installation process and reducing their work efficiency.

[0003] According to the prior art, patent number CN214008263U discloses a bushing that is easy to install. The patent allows the first bushing body and the second bushing body to be opened and closed, which is very convenient during installation and can effectively reduce the installation time of workers and improve their work efficiency.

[0004] However, in actual operation, it was found that each time the bushing was installed in this patent, one of the fixing blocks on the outer periphery of the bushing needed to be deflected to a corresponding fixing seat, and then the other fixing block needed to be deflected to another corresponding fixing seat, and then the two fixing blocks were fixed on the two fixing seats respectively through threaded rods. This operation process is cumbersome, and the threaded rod is inconvenient to operate when twisting. Utility Model Content

[0005] In order to solve the above technical problems, an easy-to-install straight bushing is provided to replace the overly cumbersome fixing method of the existing bushing opening and closing design after closing.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an easy-to-install straight bushing, comprising a first bushing body and a second bushing body in a semi-annular shape, one end of the first bushing body and one end of the second bushing body being hingedly connected, characterized in that: a buckle component is provided at the other end of the first bushing body, a notch is provided at the other end of the second bushing body, and a fastening component is provided in the notch;

[0007] The buckle component includes a fixing strip fixed to the other end of the first bushing body, and a locking strip in the shape of a right-angled trapezoid is fixed to the end of the fixing strip;

[0008] The fastening component includes a locking strip arranged in the notch and a linkage plate fixed on one side of the locking strip, the end of the linkage plate is hingedly connected to the outer wall of the second bushing body, and two springs are fixed on the innermost inner wall of the notch, and the ends of the springs are fixed to the locking strip.

[0009] Preferably, a reinforcing piece for strengthening the fastening effect of the locking strip on the locking card strip is arranged on the outer periphery of the first bushing body, and the reinforcing piece includes a clamping plate slidably arranged in a C shape on the outer periphery of the first bushing body.

[0010] Preferably, sliders are fixed to the inner walls at both ends of the clamping plate, and sliding grooves matched with the sliders are respectively formed on the upper and lower end surfaces of the first bushing body.

[0011] Preferably, the inclined surface of the locking strip faces the notch of the second bushing body.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The locking bar is then retracted to allow the locking bar to move out of the way and out of the way of the second bushing body, thereby allowing ...

[0014] (2) By setting the reinforcement piece, after the lock card strip is inserted into the lock buckle strip, the clamping plate can be pushed to move toward the side close to the lock card strip, thereby driving the sliders in the inner walls at both ends of the clamping plate to slide in the inner wall of the extended slide groove until the sliders abut against the inner wall of one side of the slide groove. At this time, the clamping plate moves to the side of the lock buckle strip and the linkage plate, so that when the spring is expanded toward the side close to the lock buckle strip due to vibration, the lock buckle strip is abutted by the inner wall of the clamping plate, thereby preventing the lock buckle strip from escaping from the buckle lock of the lock card strip.

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figures 1 to 5 As shown, an easy-to-install straight bushing includes a first bushing body 1 and a second bushing body 2 in a semi-annular shape, one end of the first bushing body 1 is hingedly connected to one end of the second bushing body 2, the other end of the first bushing body 1 is provided with a snap-fit ​​component, the other end of the second bushing body 2 is provided with a notch, and a fastening component is provided in the notch;

[0024] The buckle component includes a fixing strip 7 fixed to the other end of the first bushing body 1, and a locking strip 8 in the shape of a right-angled trapezoid is fixed to the end of the fixing strip 7, and the inclined surface of the locking strip 8 faces the notch of the second bushing body 2;

[0025] The fastening component includes a lock strip 4 arranged in the notch and a linkage plate 5 fixed on one side of the lock strip 4, the end of the linkage plate 5 is hingedly connected to the outer wall of the second bushing body 2, and two springs 9 are fixed on the inner wall of the innermost side of the notch, and the ends of the springs 9 are fixed to the lock strip 4;

[0026] Through the joint arrangement of the snap component and the fastening component, when the first bushing body 1 and the second bushing body 2 need to be closed, the locking strip 8 at the end of the fixing strip 7 is inserted into the notch on the second bushing body 2. During this process, the inclined surface of the locking strip 8 abuts against the side of the locking strip 4, causing the locking strip 4 to move along the inclined surface of the locking strip 8 toward the side away from the notch of the second bushing body 2, and due to the restriction of the linkage plate 5 and the second bushing body 2, the locking strip 4 is deflected with the end of the linkage plate 5. When the locking strip 8 penetrates and contacts the inner wall of the notch of the second bushing body 2, the locking strip 4 also moves sideways to the highest point of the inclined surface of the locking strip 8, and then The locking strip 4 is reset by the reverse pulling force of the spring 9, and the locking strip 4 is embedded between the locking strip 8 and the end face of the first bushing body 1, and then the locking strip 8 is fastened and locked in the notch of the second bushing body 2 by the locking strip 4. When the first bushing body 1 and the second bushing body 2 need to be unfolded, the locking strip 4 can be pulled to cause the locking strip 8 to disengage from the buckle of the locking strip 4, and then the first bushing body 1 and the second bushing body 2 are unfolded. In this way, the method of quickly fixing the first bushing body 1 and the second bushing body 2 after closing them by the buckle of the locking strip 8 by the locking strip 4 replaces the overly cumbersome fixing method of the existing bushing opening and closing design after closing.

[0027] However, in reality, since the spring 9 is very likely to vibrate due to external force, it may cause the locking strip 4 to be out of the locking state of the locking strip 8 .

[0028] In view of this, refer to Figures 1 to 5 As shown, it is worth noting that a reinforcing member for reinforcing the locking effect of the locking strip 4 on the locking strip 8 is arranged on the outer periphery of the first bushing body 1, and the reinforcing member includes a clamping plate 6 slidably arranged in a C shape on the outer periphery of the first bushing body 1;

[0029] Slide blocks 10 are fixed to the inner walls of both ends of the clamping plate 6, and slide grooves 3 adapted to the slide blocks 10 are respectively provided on the upper and lower end surfaces of the first bushing body 1;

[0030] When the locking bar 8 is clamped in the locking strip 4, the locking bar 4 can be prevented from being separated from the locking strip 8 by the inner wall of the clamping plate 6.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
