[0003] When using the encoder, the applicant found that if Figure 1 and Figure 2 ,The tested devices, such as manual fire alarm buttons, smoke detectors, have various distances between contacts, ,and the contact distance of the encoder cannot be changed, so it cannot be ,adaptively used. It is necessary to optimize the structure. Summary of the invention

[0004] In view of the problems raised by the above background technology, the purpose of the present invention is to provide an encoder contact piece structure.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] An encoder contact piece structure comprises a main body, on which a contact piece structure is installed, and the contact piece structure is signal-connected to the main body.

[0007] It is further defined that the contact structure includes two arc-shaped grooves provided on the main body, the two arc-shaped grooves are installed opposite to each other, contact screws are installed at the middle positions of the two arc-shaped grooves, arc-shaped contacts are installed in the arc-shaped grooves through the contact screws, an arc-shaped hole matching the specifications of the contact screws is provided in the middle position of the arc-shaped contact, and a long contact and a short contact are respectively connected integrally at both ends of the arc-shaped contact. With such a design, by sliding the arc-shaped contact in the arc-shaped groove, it is possible to achieve contact using the long contacts at both ends, or the two short contacts in the middle, or one long contact and one short contact. The use is diversified and the distance formed between the contacts is also variable. Furthermore, because of the arc-shaped structure, the change in the length of the long contact or the short contact protruding from the main body will also change the distance between the two contacts, thereby ensuring contact adaptability.

[0008] It is further defined that the contact structure includes two steel strands connected to the main body, the two steel strands are formed by winding at least two steel wires with different hardness, different elasticity and different toughness, and the ends of the two steel strands are connected with round contacts. With this design, the distance between the two round contacts can be changed by directly turning the steel strands, and the use effect is simple and direct.

[0009] It is further defined that the contact piece structure includes a plurality of retractable touch strips evenly arranged and installed on the main body, and the ends of the retractable touch strips are connected to touch plates. With such a design, stretching two retractable touch strips in different positions can adapt to detection of different widths and distances, and its retractable structure can extend into a deeper position to ensure the normal detection.

[0010] It is further defined that the contact structure includes a first branch hingedly mounted on the main body, the first branch is hingedly mounted with a second branch, and the second branch is hingedly mounted with a third branch. With such a design, by moving the first branch, the second branch and the third branch, the end of the third branch can be placed in different positions, thereby adapting to the detection of devices under test of different widths.

[0011] It is further defined that the contact structure includes a mounting groove and a limiting opening opened on the main body, a moving block is slidably installed in the mounting groove, sliding buttons protruding from the main body are installed at both ends of the moving block, two groups of clamping plates are fixedly installed on the moving block, a pulling plate is clamped and installed in one group of the clamping plates, a W-shaped contact piece is hingedly installed in one group of the clamping plates, the midpoint position of the W-shaped contact piece is the hinge point, a first spring is connected between the W-shaped contact piece and the pulling plate, and a limiting waist-shaped hole is provided in the middle position of the moving block, With such a design, sliding the slide button upwards can make the end of the W-shaped contact piece protrude from the limit opening, thereby achieving the purpose of detection; sliding the slide button downward can make the end of the W-shaped contact piece be stored in the limit opening, thereby achieving the protection effect of the W-shaped contact piece and ensuring its practical life. Furthermore, because the W-shaped contact piece is hingedly installed and its position is limited by the first spring, the W-shaped contact piece can change its angle when subjected to force, that is, the force can change the distance between the contact points of the two W-shaped contact pieces, thereby achieving the purpose of improving the adaptability of use.

[0012] The cam-shaped contact piece is hingedly installed in one of the two pressure plates, and a spring is fixedly installed in one of the two pressure plates, and a second spring is connected between the two pressure plates and the spring plate, and a matching waist-shaped hole is provided in the middle position of the sliding block. An eccentric wheel is rotatably installed on the main body, and the rotating end of the eccentric wheel protrudes from the main body, and the output end of the eccentric wheel is placed in the matching waist-shaped hole. With this design, the eccentric wheel can be rotated to change the position of the matching waist-shaped hole, thereby making the mountain-shaped contact piece protrude or be received in the opening, and under the effect of the second spring, the mountain-shaped contact piece can change its angle when subjected to force, that is, the force can change the distance between the contact points of the two mountain-shaped contact pieces, thereby achieving the purpose of improving the adaptability of use.

[0013] It is further defined that the contact structure includes a plurality of contact openings opened on the main body, the contact structure includes a plurality of sliding key openings opened on the main body, the number of positions of the sliding key openings corresponds to the contact openings, the contact structure includes a glass ball screw fixedly installed on the main body, the number of positions of the glass ball screw corresponds to the contact openings, the contact structure includes a spring installation groove installed on the main body, the number of positions of the spring installation groove corresponds to the contact openings;

With this design, sliding the sliding key can make the touch plate at the corresponding position protrude from the contact opening. Therefore, sliding the sliding keys at different positions can slide out two contact plates of different distance sizes, thereby achieving the purpose of detecting the device under test that adapts to detection points of different distance sizes.

[0015] It is further defined that the contact structure includes a plurality of contact plate openings opened on the main body, the contact structure includes a slide rail fixedly mounted on the main body, the number of positions of the slide rail corresponds to the contact plate openings, and the contact structure includes a push-type spring female buckle fixedly mounted on the main body, the number of positions of the push-type spring female buckle corresponds to the contact plate openings;

[0046] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0047] like Figure 1 As shown, an encoder contact piece structure of the present invention comprises a main body 1, on which a contact piece structure 2 is installed, and the contact piece structure 2 is connected to the main body 1 by signals.

[0048] Embodiment 1:

[0049] like Figure 3 , Figure 4When using an encoder contact structure, the arc contact 103 in the arc groove 101 is moved, and the contact screw 102 is used to fix the position of the arc contact 103 in the arc groove 101, and then the long contact 105 protruding from the main body 1 can be used. Depending on the long contact 105 or the short contact 106 protruding from the main body 1, the distance between the two contacts will also change. The composition uses two long contacts 105, two short contacts 106, and one long contact 105 and one short contact 106. Moreover, the length of the long contact 105 or the short contact 106 protruding from the main body 1 is different, and the distance between the two contacts will also change, so the adaptability is strong.

[0050] Embodiment 2:

[0051] like Figure 5 When using an encoder contact piece structure, due to the characteristics of the steel strand 201, the position between the two round contacts 202 can be changed by directly pulling the steel strand 201, and the steel strand 201 has high flexibility, so to a certain extent, the contact points at the bends can also be contacted, and it is flexible and versatile to use.

[0052] Embodiment three:

[0053] like Figure 6 , Figure 7 When using an encoder contact piece structure, the retractable contact strip 301 can be elongated by directly pulling the contact plate 302, which is suitable for contacting contacts at deeper positions. Moreover, by directly pulling the retractable contact strips 301 at different positions, the detection of contacts at different adjacent distances can be achieved. The use is simple and direct.

[0054] Embodiment 4:

[0055] like Figure 8 When using an encoder contact piece structure, by directly pulling the hinged first branch 401, the second branch 402 and the third branch 403, the end distance of the third branch 403 at both ends can be changed. Moreover, due to the characteristics of the hinged connection, the distance between the ends of the third branch 403 can be changed, and the distance in the length direction formed can also be changed, which is suitable for contact at deeper positions.

[0056] Embodiment five:

[0057] like Fig. 9 , Fig.10 , Fig.11When using an encoder contact structure, sliding the sliding button 504 located on both sides of the main body 1 can realize the movement of the W-shaped contact piece 507 in the limit opening 502. When the sliding button 504 is slid upward, the moving block 503 is driven to move upward, pushing the pulling plate 506 clamped by the clamping plate 505 and the hinged W-shaped contact piece 507 to move upward, so that the W-shaped contact piece 507 protrudes from the limit opening 502 and can be used. Moreover, because it is a hinged installation method, the angle of the W-shaped contact pieces 507 on both sides can be changed. When the angle is changed outward to both sides, the contact point distance of the two W-shaped contact pieces 507 will become longer, and vice versa. When in contact use, under the effect of the first spring 508, the contact force between the contact ends of the two W-shaped contact pieces 507 and the contact points can be guaranteed to ensure the detection effect. The setting of the limiting waist-shaped hole 509 prevents the moving block 503 from moving overtravel and coming out.

[0058] Embodiment six:

[0059] like Fig.12 , Fig.13 When using an encoder contact structure, rotating the eccentric wheel 609 on the main body 1 can make the output end of the eccentric wheel 609 move in the matching waist-shaped hole 608, thereby causing the sliding block 603 to change its position under the limit of the sliding groove 601. When the sliding block 603 moves downward, it drives the pressure plate 604 and the mountain-shaped contact piece 606 hingedly installed therebetween to move downward, so that the mountain-shaped contact piece 606 is stored and protected. Conversely, when the mountain-shaped contact piece 606 moves upward, the end of the mountain-shaped contact piece 606 protruding from the main body 1 can serve as a detection end to contact the contact point, thereby achieving the purpose of detection. Moreover, because it is a hinged installation structure, with the cooperation of the second spring 607, the distance between the contact ends of the two mountain-shaped contact pieces 606 can be changed, and the contact force during contact is guaranteed.

[0060] Embodiment seven:

[0061] like Fig.14 , Fig.15 When using an encoder contact structure, the sliding key 705 in the sliding key opening 702 can push the contact plate 706 to protrude from the main body 1 at the contact opening 701 at the corresponding position, and then contact the contact point to achieve the purpose of detection. After being pushed into place, under the effect of the glass bead screw 703 and the limiting hole 708, the contact plate 706 is not easy to move. Moreover, under the effect of the spring 707, it can play a buffering effect during contact, and it is not easy to damage the contact point and the contact plate 706. Moreover, the structure of the main body 1 can be retracted to protect the contact plate 706. Furthermore, by pushing the sliding keys 705 in different positions, the detection of contacts with different distances and sizes can be adapted, thereby ensuring the adaptability of use.

[0062] Embodiment eight:

[0063] like Fig.16 When using an encoder contact piece structure, under the effects of the push-type spring female buckle 803 and the push-type spring male buckle 807, repeated pressing can make the push-type spring male buckle 807 engage in the push-type spring female buckle 803 or disengage from the push-type spring female buckle 803. Under this feature, the touch plate 804 is pressed to apply force. When the push-type spring male buckle 807 is engaged in the push-type spring female buckle 803, the touch plate 804 is located in the main body 1 and protected. The touch plate 804 is pressed to apply force. When the push-type spring male buckle 807 is disengaged from the push-type spring female buckle 803, under the elasticity of the fourth spring 806 and the limit of the slide rail 802, the touch plate 804 can protrude from the main body 1 from the touch plate port 801, so that the detection effect can be achieved by contacting the contact point, and pressing the touch plate 804 at different positions can adapt to the detection of contacts of different distances and sizes, thereby ensuring the adaptability of use.
