Description

Technical Field

[0001] The present application relates to the field of mounting fixtures, and in particular to an internal threaded sleeve mounting fixture. Background Art

[0002] Currently, high-load electrical components used outdoors, such as circuit breakers, disconnectors, etc., usually have more mechanical parts. The sleeve with internal threads is a common component of electrical components such as circuit breakers and disconnectors. The sleeve with internal threads is threadedly connected to other components.

[0003] At present, when a sleeve with an internal thread is threadedly connected to other components, the internal threaded sleeve is mainly manually held for manual thread connection, which is laborious and inconvenient to apply torque. If a vise or other tool is used for clamping, the internal threaded sleeve is easily deformed. Utility Model Content

[0004] In order to facilitate the threaded connection between an internally threaded sleeve and other components and reduce deformation of the internally threaded sleeve, the present application provides an internally threaded sleeve installation fixture.

[0005] The internal threaded casing installation fixture provided in this application adopts the following technical solution:

[0006] A clamp for installing an internal threaded sleeve comprises two clamping blocks, which are hingedly connected by a hinge, one of the two clamping blocks serves as a fixed block, and the fixed block is used to be fixedly installed on a work surface, and a movable buckle is connected between the two clamping blocks; semicircular grooves are respectively provided on opposite sides of the two clamping blocks, and one end of the semicircular grooves is through-set, and when the movable buckle is locked, the two semicircular grooves enclose a circular hole area for accommodating the internal threaded sleeve.

[0007] By adopting the above technical solution, when the internal threaded sleeve installation fixture is used, the fixing block of the fixture is fixedly installed on the workbench, and the movable buckle is kept in a loosened state, and then the internal threaded sleeve is placed in the circular hole area formed by the two semicircular grooves, and then the movable buckle is locked, so that the two clamping blocks jointly hold the internal threaded sleeve, so as to facilitate the threaded connection of the internal threaded sleeve with other components. Under the holding action of the installation fixture, the internal threaded sleeve is not easy to loosen. When the internal threaded sleeve is threadedly connected with other components, the torque can be applied to the components that cooperate with the internal threaded sleeve by holding it with both hands or using tools, which is more convenient and labor-saving; and, when the two semicircular grooves hold the internal threaded sleeve, the internal threaded sleeve is subjected to a more balanced force and is not easily deformed by clamping. In the above process, the process of fixing the internal threaded sleeve with the installation fixture is more convenient and quick, and is not easy to affect the efficiency of the threaded connection process of the internal threaded sleeve with other components.

[0008] Optionally, the fixed block is provided with a fixed seat plate, the mounting surface of the fixed seat plate is perpendicular to the center line of the semicircular groove and the hinge center line of the hinge, the fixed seat plate is located on the side of the fixed block away from the through end of the semicircular groove, and the fixed seat plate is provided with a plurality of through holes for passing bolts.

[0009] By adopting the above technical solution, the fixed block is fixedly installed on the workbench through the fixed base plate, and the through end of the semicircular groove is away from the fixed base plate, so that the opening of the circular hole area formed by the two semicircular grooves faces upward, so that the internal threaded sleeve can remain in an upright state, which is convenient for threaded connection of the internal threaded sleeve with other components.

[0010] Optionally, the semicircular groove has an end wall at one end away from the through end, and the end wall of the semicircular groove is used to support the internal threaded sleeve.

[0011] By adopting the above technical solution, when the installation fixture has not yet clamped the internal threaded sleeve, the end wall of the semicircular groove can support the internal threaded sleeve, so that the height position of the internal threaded sleeve remains fixed, so that the internal threaded sleeve can be fixed by the installation fixture.

[0012] Optionally, the arc angle of the semicircular groove is less than 180°, and when the movable buckle is locked, a gap margin is left between the two clamping blocks.

[0013] By adopting the above technical solution, when the movable buckle is locked, there is a gap margin between the two clamping blocks, so that there is a relatively close space margin between the two clamping blocks, so that the two clamping blocks can hold the internal threaded sleeve tightly.

[0014] Optionally, a rubber damping member is embedded in the inner wall of the semicircular groove, and the rubber damping member is used to abut against the internal threaded sleeve.

[0015] By adopting the above technical solution, when the two clamps jointly clamp the internal threaded sleeve, the rubber damping member abuts against the outer peripheral surface of the internal threaded sleeve, which can increase the friction damping between the installation fixture and the internal threaded sleeve, so as to apply a greater spiral locking force between the internal threaded sleeve and other components.

[0016] Optionally, the rubber damping member is in the shape of a long strip, and the length direction of the rubber damping member is along the center line direction of the semicircular groove.

[0017] By adopting the above technical solution, the rubber damping strip is arranged in a long strip shape. When the internal threaded sleeve is inserted into the area enclosed by the two semicircular grooves, the insertion direction of the internal threaded sleeve is consistent with the length direction of the rubber damping strip, which is beneficial to reduce the resistance during the installation of the internal threaded sleeve.

[0018] Optionally, a tension spring is connected between the two clamping blocks, and the tension spring is used to force the two clamping blocks to move closer to each other.

[0019] By adopting the above technical solution, the tension spring can force the two clamps to approach each other. In the process of installing the internal threaded sleeve into the installation fixture, the two clamps are opened at a certain angle, and the tension spring undergoes elastic deformation. The elastic force generated by the deformation of the tension spring can force the two clamps to approach each other, thereby clamping the two clamps in place, which is convenient for the subsequent locking of the movable buckle.

[0020] Optionally, hooks are respectively provided at both ends of the tension spring, and the clamping block is provided with a connecting ring for the hooks to be hooked.

[0021] By adopting the above technical solution, the two ends of the tension spring are respectively hooked to the hook through the connecting ring, so that the tension spring can be easily disassembled and assembled.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the internal threaded sleeve installation fixture is used, the two clamps are used to hold the internal threaded sleeve together to facilitate the threaded connection of the internal threaded sleeve with other components. Under the holding effect of the installation fixture, the internal threaded sleeve is not easy to loosen. When the internal threaded sleeve is threadedly connected with other components, the torque can be applied to the components that cooperate with the internal threaded sleeve by holding it with both hands or using tools, which is more convenient and labor-saving.

[0024] 2. When the two clamps hold the internal threaded sleeve together, the rubber damping member abuts against the outer peripheral surface of the internal threaded sleeve, which can increase the friction damping between the installation fixture and the internal threaded sleeve, so as to apply a greater spiral locking force between the internal threaded sleeve and other components.

[0030] Example 1

[0031] The following is combined with Figure 1-3This application is described in further detail.

[0032] The present application embodiment discloses an internal threaded sleeve installation fixture. Figure 1 The internal threaded sleeve installation fixture comprises two clamping blocks 1, which are hinged by two hinges 2, and the hinges 2 are hinges. One of the two clamping blocks 1 is used as a fixed block 101, and the other is used as a movable block 102. The fixed block 101 is used to be fixedly installed on the workbench; a movable buckle 3 is connected between the two clamping blocks 1, and the movable buckle 3 is located on the side of the two clamping blocks 1 away from the hinges 2; semicircular grooves 11 are respectively provided on the opposite sides of the two clamping blocks 1, one end of the semicircular groove 11 is through-set, and the other end of the semicircular groove 11 is provided with an end wall. When the movable buckle 3 is locked, the two semicircular grooves 11 enclose a circular hole area for accommodating the internal threaded sleeve 7, so that the two clamping blocks 1 can clamp the internal threaded sleeve 7.

[0033] Reference Figure 1 The fixing block 101 is provided with a fixing seat plate 12, which is integrally connected with the fixing block 101. The fixing seat plate 12 is located on the side of the fixing block 101 away from the through end of the semicircular groove 11, and the mounting surface of the fixing seat plate 12 is perpendicular to the center line of the semicircular groove 11 and the hinge center line of the hinge 2. The fixing seat plate 12 is provided with four through holes 121, which are distributed at four corners. The through holes 121 are used to pass bolts, so that the furniture can be fixed on the workbench by bolts, and when the internal threaded sleeve 7 is fixed by the mounting fixture, the internal threaded sleeve 7 is kept perpendicular to the workbench surface, which is convenient for the disassembly and assembly of the internal threaded sleeve 7.

[0034] The arc angle of the semicircular groove 11 is less than 180°. When the movable buckle 3 is locked, a gap margin is left between the two clamping blocks 1, so that there is a relatively close space margin between the two clamping blocks 1, so that the two clamping blocks 1 can hold the internal threaded sleeve 7 tightly.

[0035] Reference Figure 2 A rubber damping member 4 is embedded in the inner wall of the semicircular groove 11. The rubber damping member 4 is in the shape of a long strip. The length direction of the rubber damping member 4 is along the center line direction of the semicircular groove 11. When the mounting fixture clamps the internally threaded sleeve 7, the rubber damping member 4 can abut against the internally threaded sleeve 7, thereby increasing the friction damping between the internally threaded sleeve 7 and the mounting fixture, so as to apply a greater spiral locking force between the internally threaded sleeve 7 and the contact arm.

[0036] The implementation principle of the internal threaded sleeve installation fixture of the embodiment of the present application is as follows: when the internal threaded sleeve installation fixture is used, the fixed block 101 of the fixture is fixedly installed on the workbench, and the movable buckle 3 is kept in a loosened state, and then the movable block 102 is pushed away from the fixed block 101, and then the internal threaded sleeve 7 is placed in the circular hole area formed by the two semicircular grooves 11, and then the movable buckle 3 is locked, so that the two clamping blocks 1 jointly hold the internal threaded sleeve 7, so as to facilitate the threaded connection between the internal threaded sleeve 7 and the contact arm. Under the holding action of the installation fixture, the internal threaded sleeve 7 is not easy to loosen, so that the connection process of the internal threaded sleeve 7 and other components is more convenient.

[0037] Example 2

[0038] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a tension spring 5 is connected between the two clamping blocks 1, and the tension spring 5 is located on the side of the fixed block 101 away from the fixed seat plate 12. The two ends of the tension spring 5 are bent to provide hooks 51, and the two clamping blocks 1 are respectively provided with connecting rings 6 for the hooks 51 to hook. The tension spring 5 is used to force the two clamping blocks 1 to approach each other.

[0039] When installing the internal threaded sleeve 7 into the installation fixture, the two clamping blocks 1 are first opened at a certain angle, and the tension spring 5 is elastically deformed. The elastic force generated by the deformation of the tension spring 5 can force the two clamping blocks 1 to move closer to each other, thereby clamping the two clamping blocks 1 in place, which is convenient for the subsequent locking of the movable buckle 3.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
