Description

Technical Field

[0001] The utility model relates to the technical field of placement racks, in particular to a furnace temperature test placement rack. Background Art

[0002] With the advancement of surface mounting technology, reflow soldering process technology and equipment have also been greatly developed, and the control requirements for welding furnace temperature are becoming higher and higher. In order to control the furnace temperature more accurately, it is necessary to transmit the furnace temperature tester to the furnace to measure the furnace temperature. Other furnaces or heating equipment also need to measure the furnace temperature. The existing technology generally transmits the furnace temperature tester to the furnace through a guide rail or a conveyor belt. The furnace temperature tester itself is not resistant to high temperatures and needs to be protected by a protective device. However, the guide rail widths of different furnaces or heating equipment are different. The furnace temperature tester of the same specification cannot adjust the width, resulting in a small scope of application.

[0003] In order to solve the above problems, a Chinese patent with announcement number CN218349648U discloses a reflow soldering oven temperature tester carrier, which includes a main body and one or two adjustment arms; the main body includes a first cavity with an opening and two first support frames respectively arranged on both sides of the opening relative to the first cavity; the adjustment arm includes a second support frame and two adjustment bars in the middle that can be uniaxially rotatably connected to each other; the first support frame includes a first guide rail; one end of the two adjustment bars are respectively uniaxially rotatably connected to the first support frame and slidably connected to the first guide rail; the second support frame includes a second guide rail; the other ends of the two adjustment bars are respectively uniaxially rotatably connected to the second support frame and slidably connected to the second guide rail; one end of the adjustment bar can be fixed relative to the first guide rail; the other end of the adjustment bar can be fixed relative to the second guide rail. Among them, the adjustment bar is connected to the first guide rail and the second guide rail respectively through a first rotating shaft; the first rotating shaft is a bolt assembly, which includes bolts and nuts, and slides and uniaxially rotates along the first guide rail and the second guide rail through the bolts.

[0004] Although the utility model uses an adjusting arm to perform stepless adjustment of the width of the carrier, saving the expense and cycle of manufacturing a large number of carriers of different specifications and saving costs, it is found during use that the adjustment bar slides and is fixed in the guide rail by bolts and nuts. Since the bolts slide by fitting through the gap with the long through hole of the guide rail, one side of the bolt is easily squeezed against the long through hole during manual adjustment, resulting in adjustment jamming and inconvenience in expanding or contracting the adjustment arm. Utility Model Content

[0005] In view of the above problems in the prior art, the utility model provides a furnace temperature test placement rack, which solves the problem that the existing furnace temperature tester carrier has a small application range due to the inability to adjust the width.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A furnace temperature test placement rack is provided, comprising a frame body which is rectangular in top view projection, and width adjustment components are arranged on the two long sides of the frame body; each width adjustment component comprises a first fixed plate and a second fixed plate fixed on the long side of the frame body, a first guide groove is provided on the first fixed plate, and a guide telescopic rod which is telescopic along the direction of the first guide groove is fixed on the first fixed plate; the second fixed plate is hinged to one side of one end of a scissor-type telescopic member, the other side of one end of the scissor-type telescopic member is hinged to the guide telescopic rod and is slidably arranged in the first guide groove, and a support plate is arranged on the other end of the scissor-type telescopic member.

[0008] In this solution, by adjusting the extension degree of the scissor-type telescopic parts on both sides of the frame, the spacing between the two support plates can be changed, so that the furnace temperature tester can be placed on welding furnace tracks of different widths through the frame, which increases the scope of application and reduces the cost of using furnace temperature tester carriers of different widths. In addition, the setting of the guide telescopic rod limits the freedom of movement of the bottom of the scissor-type telescopic part, and does not cause the scissor-type telescopic part to collide with the first guide groove and cause jamming, making the adjustment smoother.

[0009] Furthermore, a second guide groove is opened on one end of the support plate, and the central axis of the second guide groove is arranged parallel to the central axis of the first guide groove. One side of the scissor-type telescopic member is hinged on one end of the support plate, and the other side of the scissor-type telescopic member is hinged and slidably arranged in the second guide groove.

[0010] Further, the scissor-type telescopic member includes a first adjustment bar and a second adjustment bar, one end of the first adjustment bar is hinged to the support plate, the other end of the first adjustment bar is provided with a first hinge hole which matches with the first bolt, a bearing is fixed on the telescopic end of the guide telescopic rod, the first bolt passes through the first hinge hole, the center hole of the bearing and the first guide groove in sequence and is fixedly connected with the nut; one end of the second adjustment bar is hinged to the second fixed plate, the other end of the second adjustment bar is provided with a second hinge hole which matches with the second bolt, the second bolt passes through the second hinge hole and the second guide groove in sequence and is fixedly connected with the nut. Due to the restriction of the guide telescopic rod, the moving direction of the first bolt can only move along the central axis of the first guide groove, so that the first bolt will not conflict with the inner wall of the first guide groove, thereby ensuring that the first bolt can move in the first guide groove, and the first bolt can also be fixed in the first guide groove through the nut, and the guide telescopic rod can also be used to adjust the moving distance of the first bolt in the first guide groove.

[0011] Further, the first bolt and the second bolt are respectively loosely matched with the first guide groove and the second guide groove.

[0012] Furthermore, the first bolt and the second bolt are both butterfly bolts, which are convenient to be manually screwed.

[0013] Furthermore, the first fixing plate and the second fixing plate are both L-shaped plates, and the first fixing plate and the second fixing plate are integrally formed with the frame.

[0014] Furthermore, the short sides of both sides of the frame are fixed with limit baffles, and both the limit baffles and the L-shaped plates can prevent the furnace temperature tester from falling.

[0015] Furthermore, four through holes symmetrically arranged in pairs are formed on the end surface of the frame.

[0016] Furthermore, each through hole is L-shaped, and each through hole includes a vertical section and a horizontal section, the height of the vertical section is 1 / 2 to 1 / 3 of the height of the horizontal section, and the length of the vertical section is 3 to 5 times the length of the horizontal section. The shape of the through hole is set in this way, while ensuring that the furnace temperature tester can be supported, the weight of the frame is reduced, and it is also convenient for the furnace temperature tester to measure temperature.

[0017] Furthermore, the frame is made of stainless steel.

[0018] The utility model discloses a furnace temperature test placement rack, which has the following beneficial effects:

[0019] The utility model can change the distance between the two support plates by adjusting the extension degree of the scissor-type telescopic parts on both sides of the frame, so that the furnace temperature tester can be placed on welding furnace tracks of different widths through the frame, thereby increasing the scope of application and reducing the cost of using furnace temperature tester carriers of different widths. In addition, the setting of the guide telescopic rod limits the freedom of movement of the bottom of the scissor-type telescopic part, so that the scissor-type telescopic part will not conflict with the first guide groove to cause jamming, and the adjustment is smoother.

DETAILED DESCRIPTION

[0024] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0025] refer to Figure 1 This embodiment provides a furnace temperature test rack, including a rack body 1 and two width adjustment components 2.

[0026] The frame 1 is rectangular in top view and is made of stainless steel. Figure 3 Four through holes 11 are symmetrically arranged in pairs on the end surface of the frame 1. Each through hole 11 is L-shaped, and each through hole 11 includes a vertical section 111 and a horizontal section 112. The height of the vertical section 111 is 1 / 2 to 1 / 3 of the height of the horizontal section 112, and the length of the vertical section 111 is 3 to 5 times the length of the horizontal section 112. The shape of the through holes 11 is set in this way, which ensures that the furnace temperature tester can be supported while reducing the weight of the frame 1, and is also convenient for the furnace temperature tester to measure temperature.

[0027] The short sides of the frame 1 are both fixed with limit baffles 12. The limit baffles 12 and the L-shaped plate can prevent the furnace temperature tester from falling.

[0028] The width adjustment components 2 are arranged on the two long sides of the frame body 1. Specifically, each width adjustment component 2 includes a first fixing plate 21 and a second fixing plate 22 fixed on the long sides of the frame body 1, and the first fixing plate 21 and the second fixing plate 22 are both L-shaped plates, and the first fixing plate 21 and the second fixing plate 22 are integrally formed with the frame body 1.

[0029] A first guide groove 212 is defined on the first fixing plate 21 , and a guide telescopic rod 211 is fixed on the first fixing plate 21 to extend and retract along the direction of the first guide groove 212 .

[0030] The second fixing plate 22 is hinged to one side of one end of the scissor-type telescopic member 23, the other side of one end of the scissor-type telescopic member 23 is hinged to the guide telescopic rod 211 and slidably arranged in the first guide groove 212, and a support plate 24 is arranged on the other end of the scissor-type telescopic member 23. The setting of the guide telescopic rod 211 limits the freedom of movement of the bottom of the scissor-type telescopic member 23, and does not cause the scissor-type telescopic member 23 to collide with the first guide groove 212 to cause jamming, and the adjustment is smoother.

[0031] As a further solution of this embodiment, a second guide groove 241 is opened on one end of the support plate 24, and the central axis of the second guide groove 241 is arranged parallel to the central axis of the first guide groove 212. One side of the scissor-type telescopic member 23 is hinged on one end of the support plate 24, and the other side of the scissor-type telescopic member 23 is hinged and slidably arranged in the second guide groove 241.

[0032] Specifically, the scissor-type telescopic member 23 includes a first adjustment bar 231 and a second adjustment bar 232. One end of the first adjustment bar 231 is hinged to the support plate 24, and the other end of the first adjustment bar 231 is provided with a first hinge hole that is clearance-matched with the first bolt 213. Figure 2 A bearing 214 is fixed on the telescopic end of the guide telescopic rod 211, and the first bolt 213 passes through the first hinge hole, the center hole of the bearing 214 and the first guide groove 212 in sequence and is fixedly connected with the nut. Due to the restriction of the guide telescopic rod 211, the movement direction of the first bolt 213 can only move along the central axis of the first guide groove 212, so that the first bolt 213 will not conflict with the inner wall of the first guide groove 212, thereby ensuring that the first bolt 213 can move in the first guide groove 212, and the first bolt 213 can also be fixed in the first guide groove 212 through the nut, and at the same time, the locking function of the guide telescopic rod 211 can be used to adjust the moving distance of the first bolt 213 in the first guide groove 212 without locking the nut on the first bolt 213.

[0033] One end of the second adjustment bar 232 is hinged to the second fixing plate 22, and the other end of the second adjustment bar 232 is provided with a second hinge hole matched with the second bolt 242. The second bolt 242 passes through the second hinge hole and the second guide groove 241 in sequence to be fixedly connected with the nut.

[0034] Preferably, but not limited to, the first bolt 213 and the second bolt 242 are respectively loosely matched with the first guide groove 212 and the second guide groove 241. The first bolt 213 and the second bolt 242 are both butterfly bolts, which are convenient for manual tightening.

[0035] In summary, the beneficial effects of this embodiment are:

[0036] This embodiment improves the scope of application and reduces the cost of using furnace temperature tester carriers of different widths. By adjusting the degree of expansion and contraction of the scissor-type expansion and contraction members 23 on both sides of the frame 1, the spacing between the two support plates 24 can be changed, so that the furnace temperature tester can be placed on welding furnace tracks of different widths through the frame 1, thereby improving the scope of application and reducing the cost of using furnace temperature tester carriers of different widths.
