Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of core clamps, in particular to a position limiting and locking device for a handle of a core clamp. Background Art
[0002] At present, the movable handle of the core clamp is easy to loosen when it moves to the open and locked positions, which leads to unstable clamping of the workpiece by the clamp. Therefore, a core clamp handle limit locking device is needed to solve the above problem. Utility Model Content
[0003] The purpose of the embodiment of the utility model is to provide a limit locking device for the handle of a lower core clamp, which aims to solve the problem of loosening of the handle when it is moved to the open or locked position.
[0004] The utility model is implemented as follows: a lower core clamp handle limit locking device comprises: a sliding guide rail and a positioning hole, wherein the positioning hole is provided on the sliding guide rail, and two positioning holes are provided; a spring housing, which is slidably arranged on the sliding guide rail, and the spring housing can stably slide along the sliding guide rail, and a movable handle for controlling the stable sliding of the spring housing along the sliding guide rail is fixedly installed on the spring housing; a locking mechanism is installed on the spring housing, and the locking mechanism can enter the positioning hole provided by the sliding guide rail under the push of elastic force, so as to lock the handle.
[0005] Preferably, the locking mechanism includes: a pressure spring, which is fixedly arranged in a spring housing, and a positioning steel ball is fixedly connected to one end of the pressure spring away from the spring housing. The positioning steel ball and the positioning hole are arranged in cooperation with each other, and the pressure spring is used to push the positioning steel ball into the positioning hole to lock the movable handle.
[0006] The utility model discloses a core clamp handle limit locking device, the movable handle of the core clamp handle can be stably locked when it reaches the opening and locking positions to avoid loosening, thereby ensuring that the core clamp holds the workpiece stably, and the operation is simple and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic diagram of the structure of the limit locking device of the lower core clamp handle.
[0008] In the accompanying drawings: 1-sliding guide rail, 2-positioning hole, 3-spring housing, 3-spring housing, 4-moving handle, 5-locking mechanism, 51-pressure spring, 52-positioning steel ball. DETAILED DESCRIPTION
[0009] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.
[0010] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0011] See also Figure 1 The embodiment of the utility model provides a lower core clamp handle limit locking device, the lower core clamp handle limit locking device comprises:
[0012] A sliding guide rail 1 and a positioning hole 2, wherein the positioning hole 2 is provided on the sliding guide rail 1, and two positioning holes 2 are provided; a spring housing 3, which is slidably arranged on the sliding guide rail 1, and the spring housing 3 can stably slide along the sliding guide rail 1, and a movable handle 4 for controlling the stable sliding of the spring housing 3 along the sliding guide rail 1 is fixedly installed on the spring housing 3; a locking mechanism 5, which is installed on the spring housing 3, and the locking mechanism 5 can enter the positioning hole 2 provided on the sliding guide rail 1 under the push of elastic force, and is used to lock the handle.
[0013] like Figure 1 As shown, as a preferred embodiment of the utility model, the locking mechanism 5 includes: a pressure spring 51, which is fixedly arranged in the spring housing 3, and the end of the pressure spring 51 away from the spring housing 3 is fixedly connected with a positioning steel ball 52, the positioning steel ball 52 and the positioning hole 2 are matched with each other, and the pressure spring 51 is used to push the positioning steel ball 52 into the positioning hole 2 to lock the movable handle 4.
[0014] Working principle: After the movable handle 4 is moved to the required position, the positioning steel ball 52 pops out under the pressure of the pressure spring 51, so that the pressure spring enters the positioning hole 2 opened in the sliding track 1, thereby locking the movable handle 4. The problem of the movable handle 4 being loose when moved to the open and locked positions is solved.
[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
