Description

Technical Field

[0001] This invention relates to the field of rod locking technology, and in particular to a rod support and rod locking method. Background Technology

[0002] In the field of pole connection technology, there are two main types of connection methods: fixed connection and detachable connection. Fixed connection is mainly achieved by welding or gluing to fix the pole and cannot be disassembled later. Detachable connection, on the other hand, uses clips or screws to fix the pole and can be disassembled when needed.

[0003] For detachable connection methods, the commonly used connection structure known to the applicant is the screw tightening structure, which has good locking performance while being detachable. The specific structure of the connecting rod using screws for detachable connection is as follows: a screw is bolted to the side of the main body with an insertion hole. The screw can be screwed into the insertion hole and abuts against the connecting rod in the insertion hole to complete the connection of the connecting rod. However, this structure generally requires the screw to be tightened with a wrench to ensure a firm lock, which is relatively cumbersome and prone to problems such as excessive torque causing the screw to break and become stuck in the screw hole.

[0004] Therefore, there is an urgent need for a rod support that improves ease of operation while maintaining good locking performance. Summary of the Invention

[0005] The purpose of this invention is to provide a connecting rod bracket and a connecting rod locking method to solve the problems existing in the prior art. It utilizes the lever principle to lock the connecting rod, which is highly convenient to operate and has a good locking effect.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a connecting rod bracket, including a bracket body and a lever arm. The bracket body is provided with an insertion hole for inserting a connecting rod. The lever arm is hinged to the bracket body. A through hole is provided on the inner wall of the insertion hole for one end of the lever arm to be screwed in. The other end of the lever arm is located outside the bracket body and is connected to a linear telescopic mechanism. The telescopic end of the linear telescopic mechanism is positioned facing the bracket body. The distance between the hinge point of the lever arm and the bracket body and the end of the lever arm near the through hole is less than the distance between the hinge point of the lever arm and the bracket body and the end of the lever arm away from the through hole.

[0007] Preferably, the linear telescopic mechanism is a screw, which is threaded onto the lever arm, with the head of the screw located on the side of the lever arm away from the support body.

[0008] Preferably, the head of the screw is provided with anti-slip texture.

[0009] Preferably, the lever arm has a groove on its end face near the support body. The groove is located between the hinge point of the lever arm and the support body and the end of the lever arm away from the through hole. A spring is provided in the groove, and one end of the spring extends out of the groove and abuts against the support body.

[0010] Preferably, the support body has a shaft hole, the lever arm has a rotating hole, and the rotating shaft passes through the shaft hole and the rotating hole.

[0011] Preferably, the end face of the lever arm near the through hole is concave arc-shaped.

[0012] Preferably, the diameter of the insertion hole is larger than the diameter of the connecting rod to be inserted, and a strip groove is provided on the inner wall of the insertion hole, with the groove opening corresponding to the through hole.

[0013] Preferably, the support body is provided with a connecting threaded hole for positioning the support body.

[0014] Preferably, the insertion hole has an enlarged opening.

[0015] The present invention also provides a method for locking the connecting rod using the above-mentioned connecting rod bracket, comprising the following steps: S1: Insert the connecting rod into the insertion hole of the bracket body; S2: Controls the extension of the linear telescopic mechanism, pushes the lever arm to rotate around the hinge point, and the end of the lever arm near the through hole is screwed into the through hole and abuts against the connecting rod in the insertion hole; S3: Control the linear telescopic mechanism to continue extending until the locking rod is in the insertion hole.

[0016] The present invention achieves the following main technical effects compared to the prior art: The lever arm design utilizes the lever principle. When the portion of the linear telescopic mechanism located between the lever arm and the support body extends or retracts, it causes one end of the lever arm to rotate. Since the lever arm is hinged to the support body, the other end of the lever arm also rotates, thus screwing into the through hole to press the connecting rod in the insertion hole, thereby locking the connecting rod. Alternatively, it can be screwed out of the through hole to release the pressing force on the connecting rod in the insertion hole, thereby unlocking the connecting rod. Furthermore, the lever arm between the linear telescopic mechanism and the hinge point is relatively long, allowing for a secure locking of the connecting rod with a smaller force, improving operational convenience. At the same time, during the process of the lever arm pressing and locking the connecting rod, the connecting rod will not rotate or slide as in traditional screw-tightening structures, allowing the connecting rod to be infinitely adjustable according to the application scenario.

[0017] Other solutions of the present invention achieve the following technical effects compared with the prior art: The design of the strip groove can work with the lever arm to achieve three-point positioning of the connecting rod from both sides, further improving the locking effect of the connecting rod.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide a connecting rod bracket and a connecting rod locking method to solve the problems existing in the prior art. It utilizes the lever principle to lock the connecting rod, which is highly convenient to operate and has a good locking effect.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to the following: Figures 1-4As shown, a connecting rod bracket is provided, including a bracket body 1 and a lever arm 3. The bracket body 1 is provided with an insertion hole 2 for inserting a connecting rod. The lever arm 3 is hinged to the bracket body 1. A through hole is provided on the inner wall of the insertion hole 2 for one end of the lever arm 3 to be screwed in. The other end of the lever arm 3 is located outside the bracket body 1 and is connected to a linear telescopic mechanism. The linear telescopic mechanism can be a manual telescopic mechanism or an automatic telescopic mechanism. The telescopic end of the linear telescopic mechanism is set towards the bracket body 1. The distance between the hinge point of the lever arm 3 and the bracket body 1 and the end of the lever arm 3 near the through hole is less than the distance between the hinge point of the lever arm 3 and the bracket body 1 and the end of the lever arm 3 away from the through hole. The end of the lever arm 3 near the linear telescopic mechanism can be defined as the force-applying end, and the end of the lever arm 3 near the through hole can be defined as the compression end. The force-applying end and the hinge... The lever arm between the points is greater than the lever arm between the pressing end and the hinge point, allowing a smaller force to be used at the applying end to achieve a larger pressing force at the pressing end. When it is necessary to lock the connecting rod in the insertion hole 2, the part of the linear telescopic mechanism located between the lever arm 3 and the bracket body 1 can be extended by controlling the linear telescopic mechanism to make the lever arm 3 rotate. The pressing end then presses the connecting rod to complete the locking of the connecting rod. The force required to extend the linear telescopic mechanism during this process is small, improving the ease of operation. At the same time, the connecting rod will not rotate or slide, allowing the connecting rod to be infinitely adjustable according to the application scenario. When it is necessary to unlock the connecting rod in the insertion hole 2, the part of the linear telescopic mechanism located between the lever arm 3 and the bracket body 1 can be shortened by controlling the linear telescopic mechanism. At this time, the pressing force at the pressing end is released, the lever arm 3 can rotate in the opposite direction, and the connecting rod can be freely released from the insertion hole 2.

[0024] In this embodiment, the linear telescopic mechanism is a manual telescopic mechanism, specifically a screw 4. The screw 4 is threaded onto the lever arm 3, and the head of the screw 4 is located on the side of the lever arm 3 away from the support body 1. By turning the screw 4, the length of the part of the screw 4 located between the lever arm 3 and the support body 1 can be controlled so as to complete the locking or unlocking operation.

[0025] In other embodiments, the linear telescopic mechanism is an automatic telescopic mechanism, specifically an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod, etc. This mechanism is directly mounted on the lever arm 3, and the length of the part located between the lever arm 3 and the support body 1 is adjusted by the telescopic movement of the telescopic rod, so as to complete the locking or unlocking operation.

[0026] When using screw 4 as a linear telescopic mechanism, anti-slip texture is provided on the head of screw 4. The presence of anti-slip texture allows the user to apply force more conveniently. The anti-slip texture can be straight knurled.

[0027] In one embodiment, a groove 5 is provided on the end face of the lever arm 3 near the support body 1. The groove 5 is located between the hinge point of the lever arm 3 and the support body 1 and the end of the lever arm 3 away from the through hole. A spring 6 is provided in the groove 5. The spring 6 can be fixedly connected to the groove 5 or abut against the groove 5. One end of the spring 6 extends out of the groove 5 and abuts against the support body 1. The spring 6 is always in a compressed state, which can provide a certain elastic force to the force-applying end to cooperate with the linear telescopic mechanism to complete the squeezing action of the connecting rod. The presence of elastic force can further reduce the force applied to the linear telescopic mechanism and further improve the ease of operation.

[0028] In this embodiment, a shaft hole 7 is provided on the support body 1, and a rotating hole is provided on the lever arm 3. The rotating shaft 8 passes through the shaft hole 7 and the rotating hole to achieve the hinge connection between the lever arm 3 and the support body 1. The rotating shaft 8 can be made of a pin. After the pin passes through the shaft hole 7 and the rotating hole, glue can be used to fix the pin to the shaft hole 7.

[0029] In other embodiments, a hinge seat may be provided on the support body 1 to complete the hinge connection with the lever arm 3.

[0030] In one embodiment, the end face of the lever arm 3 near the through hole is concave arc-shaped so that it can be used for squeezing and positioning the connecting rod.

[0031] In other embodiments, the end face of the lever arm 3 near the through hole can be planar, spherical, or similar, as long as it can achieve the compression and locking of the connecting rod.

[0032] In one embodiment, the diameter of the insertion hole 2 is larger than the diameter of the connecting rod to be inserted. A strip groove 9 is provided on the inner wall of the insertion hole 2. The strip groove 9 is of the same length as the insertion hole 2, and the groove opening of the strip groove 9 corresponds to the through hole. The design of the strip groove 9 can cooperate with the lever arm 3 to achieve three-point positioning of the connecting rod from both sides. The three-point positioning refers to the positioning of the pressing point of the lever arm 3 and the positioning of the two lines at the two turning lines between the strip groove 9 and the inner wall of the insertion hole 2. The three-point positioning method can further improve the locking effect of the connecting rod.

[0033] In one embodiment, in order to facilitate the positioning and installation of the bracket body 1, a connecting threaded hole 11 for positioning the bracket body 1 is provided on the bracket body 1. The connecting threaded hole 11 can be formed by: providing an internal thread at the bottom of the insertion hole 2 of the bracket body 1 and threading a base 10 with an external thread, and opening the connecting threaded hole 11 on the base 10. The base 10 can be connected to the bracket body 1 in other ways, such as snap-fit ​​or integral molding.

[0034] The base 10 can be a copper base 10. The self-lubricating and wear-resistant properties of copper can improve the smoothness of the connection between the threaded hole 11 and other equipment.

[0035] When the base 10 is threadedly connected to the insertion hole 2, an adhesive application can be performed before insertion to enhance the connection strength between the base 10 and the insertion hole 2 by utilizing the adhesive properties of the glue.

[0036] In one embodiment, the opening of the insertion hole 2 is flared, that is, the opening of the insertion hole 2 has an inverted frustum-shaped structure, which can play a certain guiding role for the inserted connecting rod.

[0037] The present invention also provides a method for locking the connecting rod using the above-mentioned connecting rod bracket, comprising the following steps: S1: Insert the connecting rod into the insertion hole 2 of the bracket body 1; S2: Control the linear telescopic mechanism to extend (tighten screw 4 or control the telescopic rod to extend), push the lever arm 3 to rotate around the hinge point, and screw the end of the lever arm 3 near the through hole into the through hole and abut against the connecting rod in the insertion hole 2. S3: Control the linear telescopic mechanism to continue to extend, the force of lever arm 3 pressing the connecting rod continuously increases until the connecting rod is locked in the position of insertion hole 2.

[0038] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
