Description

Technical Field

[0001] This utility model relates to the field of loudspeaker processing technology, and in particular to a positioning fixture for loudspeaker transfer. Background Technology

[0002] After the horn is processed, it is often placed in such a place. Figure 6 The positioning fixture shown includes a rigid backing plate 2, on which a foam board 1 is attached. The foam board 1 has multiple constraint holes 20. The speaker is placed in the constraint holes 20. This positioning fixture has a low cost, but its prominent feature is that it is easy to be damaged, so its reusability is poor. Furthermore, the speaker is fixed by the contraction force generated by the deformation of the constraint holes 20, which has poor stability and is prone to falling off during the transfer process. Utility Model Content

[0003] This utility model provides a positioning fixture for horn transfer, which solves the shortcomings of the prior art and addresses the problem of poor reusability of existing positioning fixtures, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A positioning fixture for transferring a loudspeaker includes a placement plate with multiple rows of limiting holes. The lower end of each limiting hole is integrally formed with a bottom cover, the lower end of which protrudes from the lower wall of the placement plate. An upper push rod passes through the bottom cover, and a push plate is provided at the upper end of the upper push rod. The limiting holes limit the loudspeaker placed inside, while the push plate on the upper part facilitates lifting the loudspeaker, thereby making it easy to remove the loudspeaker.

[0006] Multiple rubber strips are formed on the inner circumference of the limiting hole. The horn is placed in the limiting hole and on the push plate, and the rubber strips abut against the periphery of the horn. The rubber strips have the ability to deform, so as to limit the horn placed in the limiting hole.

[0007] Furthermore, a rotating rod is rotatably provided on one side of each limiting hole, and an upper clamping plate is threadedly connected to the upper end of the rotating rod. The upper clamping plate is located directly above each corresponding limiting hole, and can limit the horn located below it to prevent the horn from falling off.

[0008] Furthermore, the other end of the upper plate is provided with an upper protrusion rod, which the operator can hold to rotate the upper plate.

[0009] Furthermore, each upper protruding rod is fitted with a support plate, and the support plate has an oblong hole. The upper protruding rod passes through the oblong hole. One end of the support plate located in the same column or row is formed with a pull plate. Through the setting of the pull plate and the oblong hole, it is convenient to rotate multiple upper clamping plates at the same time, thereby facilitating the cancellation of limit operation of multiple horns.

[0010] Furthermore, one end of the pull plate is formed with an end plate, and an L-shaped retaining plate abuts against the outer wall of the end plate. The upper end of the L-shaped retaining plate acts on the upper wall of the pull plate. A pair of spring pins are provided on the L-shaped retaining plate, and an end sleeve plate is fitted onto the spring pins. The end sleeve plate is installed on the placement plate by screws. A tightening spring is fitted onto the spring pins, and the tightening spring is located between the end sleeve plate and the L-shaped retaining plate. The tightening spring allows the L-shaped retaining plate to position the pull plate vertically and along its length.

[0011] Furthermore, in order to automatically push the horn out, a pair of limiting rings are provided at the lower end of the upper push rod. An upper push spring is sleeved on the upper push rod. The upper end of the upper push spring abuts against the push plate, and the lower end of the upper push spring abuts against the lower end of the bottom cover. A swing plate is fixed at the lower end of the rotating rod. An arc-shaped groove is opened on the swing plate. The upper push rod passes through the arc-shaped groove, and the limiting rings are located on the upper and lower sides of the swing plate.

[0012] Furthermore, in order to limit the rotation and position of the rotating rod, a lower extension sleeve is fitted on the rotating rod. The lower extension sleeve is located on the bottom surface of the placement plate, and a lower end ring is provided on the rotating rod, which is located at the lower end of the lower extension sleeve.

[0013] The advantages of the above technical solution are:

[0014] This invention can position the speaker and automatically lift it up, making it easy to remove and improving its reusability. Attached Figure Description

[0021] Figure 6 A three-dimensional structural diagram of an existing horn positioning fixture is shown. Detailed Implementation

[0022] like Figures 1-5 As shown, a positioning fixture for transferring a loudspeaker includes a placement plate 3 with multiple rows of limiting holes 30. Multiple rubber strips are formed on the inner circumference of each limiting hole 30. A bottom cover 31 is integrally formed at the lower end of each limiting hole 30, protruding from the lower wall of the placement plate 3. An upper push rod 5 passes through the bottom cover 31, and a push plate 501 is provided at the upper end of the upper push rod 5. The loudspeaker is placed within the limiting hole 30 and on the push plate 501, with the rubber strips abutting against the periphery of the loudspeaker.

[0023] Each limiting hole 30 has a rotating rod 51 rotatably mounted on one side. The upper end of the rotating rod 51 is threadedly connected to an upper clamping plate 55. The other end of the upper clamping plate 55 is provided with an upper protruding rod 56. The upper clamping plate 55 is located directly above each corresponding limiting hole 30. Each upper protruding rod 56 is fitted with a support plate 57. The support plate 57 has an oblong hole 58. The upper protruding rod 56 passes through the oblong hole 58. One end of the support plate 57 located in the same column or row is formed with a pull plate 59. One end of the pull plate 59 is formed with an end plate 60, and one end of the pull plate 59 is provided with an end baffle. The end baffle is installed on the placement plate 3. An L-shaped clamping plate 64 abuts against the outer wall of the end plate 60. The upper end of the L-shaped clamping plate 64 acts on the upper wall of the pull plate 59. A pair of spring pins 62 are provided on the L-shaped clamping plate 64. An end sleeve plate 61 is sleeved on the spring pins 62. The end sleeve plate 61 is installed on the placement plate 3 by screws. A tightening spring 63 is sleeved on the spring pins 62. The tightening spring 63 is located between the end sleeve plate 61 and the L-shaped clamping plate 64.

[0024] The lower end of the upper push rod 5 is provided with a pair of limiting rings 50. An upper push spring 500 is sleeved on the upper push rod 5. The upper end of the upper push spring 500 abuts against the push plate 501, and the lower end of the upper push spring 500 abuts against the lower end of the bottom cover 31. A swing plate 53 is fixed to the lower end of the rotating rod 51. An arc-shaped groove 54 is opened on the swing plate 53. The upper push rod 5 passes through the arc-shaped groove 54, and the limiting rings 50 are located on the upper and lower sides of the swing plate 53. A lower extension sleeve 7 is sleeved on the rotating rod 51. The lower extension sleeve 7 is located on the bottom surface of the placement plate 3. A lower end ring 52 is provided on the rotating rod 51. The lower end ring 52 is located at the lower end of the lower extension sleeve 7.

[0025] When placing the speakers: the operator places the diaphragm side of each speaker onto the push plate 501 one by one. This placement effectively protects the diaphragm from damage. Then, the operator presses down on each speaker within the limiting hole 30, causing the limiting hole 30 to move downwards. During this movement, the upper spring 500 is compressed until the speaker is fully within the limiting hole 30. The operator then rotates the upper clamping plate 55 using the upper protruding rod 56, causing the upper clamping plate 55 to rotate directly above the limiting hole 30. Simultaneously, the upper rod 50 passes through the arc-shaped groove 54, and the limiting ring 50 is located on the upper and lower sides of the swing plate 53. Next, the pull plate 59 is moved downwards, and the upper protruding rod 56 passes through the oblong hole 58. One end of the pull plate 59 is limited by the end baffle, while the other end pushes the L-shaped clamping plate 64 outwards. The elastic force provided by the tightening spring 63 then stably fixes the position of the pull plate 59. Furthermore, due to the limiting effect of the L-shaped card plate 64, the pull plate 59 will not move in the vertical direction.

[0026] When removing the horn: The operator moves the pull plate 59 upwards. During this movement, the limiting position of the L-shaped clamping plate 64 is first released, and then the pull plate 59 is moved upwards until the end of the pull plate 59 and the end baffle are no longer in contact. The pull plate 59 is then pulled, causing the oblong hole 58 to act on the upper protruding rod 56, thereby causing the upper clamping plate 55 to rotate outwards. Simultaneously, the upper push rod 5 moves out of the arc-shaped groove 54. The horn will then be lifted by the upper push spring 500. The horn can then be transferred.
