Description

Technical Field

[0001] This utility model relates to the field of laser level technology, specifically a clamping bracket used with a laser level hanger. Background Technology

[0002] Laser levels are typically used with a level bracket. The laser level can be fixed to the lifting frame of the level bracket, which can be used on the ground or with a clamping device. The level bracket can be magnetically attached to the clamping device, with magnets on the back of the bracket and a metal plate on the clamping device, thus securing them together. The clamping device has two clamps, one of which is fixed, while the other can move left and right. This clamp is secured with screws; loosening the screws allows the clamp to move, and the screws must be tightened after selecting the appropriate position. This process is time-consuming and laborious, requiring tools and needs further improvement. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a clamping frame.

[0004] The technical solution of this utility model is: a clamping frame, including a support frame and a slide table, the slide table being slidably connected to the support frame, both the support frame and the slide table being L-shaped, the support frame having a first clamping plate at the left end, the slide table having a baffle at the right end, a second clamping plate being installed on the slide table and slidingly cooperating with the slide table, the first clamping plate, the second clamping plate and the baffle being distributed from left to right, the second clamping plate being connected to a driving device for moving the second clamping plate left and right, the driving device including a knob, an iron plate being fixed at the bottom of the support frame, and a magnet for attracting the iron plate being fixed at the lower end of the slide table.

[0005] Furthermore, the lower end of the support frame has multiple sliding grooves extending to the left and right, and the lower end of the slide table slides in a sliding engagement with the sliding grooves. A stop block is protruding at the right end of the bottom of the slide table, and the stop block is used to abut against the inner wall of the sliding groove.

[0006] Furthermore, the lower left end of the slide is rotatably connected to a rotating shaft that extends back and forth, and the lower end of the support frame has a stop bar that blocks the rotating shaft.

[0007] Furthermore, the drive device also includes a nut platform, a lead screw nut, and a lead screw. The slide is provided with a track extending to the left and right. The nut platform is located between the second clamping plate and the baffle. The lower end of the nut platform slides in a left-right engagement with the track. The lead screw nut is fixed on the upper end of the nut platform. The lead screw extends to the left and right, passes through the lead screw nut, and engages with the lead screw nut. The left end of the lead screw passes through the second clamping plate and is connected to the second clamping plate by fasteners.

[0008] Furthermore, the fasteners include a fastening screw and a retaining ring, and the lead screw includes a lead screw body and a short shaft located at the left end of the lead screw body. The diameter of the short shaft is smaller than the diameter of the lead screw body. The retaining ring is fitted on the short shaft and rests against the right end of the second clamping plate. A fastening screw is screwed on the left end of the short shaft, and the head of the fastening screw rests against the inner wall of the middle part of the second clamping plate.

Detailed Implementation

[0017] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0018] like Figure 1 — Figure 6As shown, a clamping frame includes a support frame 1 and a slide 2. The slide 2 is slidably connected to the support frame 1. Both the support frame 1 and the slide 2 are L-shaped. The left end of the support frame 1 has a first clamping plate 1.1, and the right end of the slide 2 has a baffle 21. A second clamping plate 3 is installed on the slide 2 and slides left and right in cooperation with the slide 2. The first clamping plate 1.1, the second clamping plate 3, and the baffle 21 are distributed from left to right. The second clamping plate 3 is connected to a driving device for moving the second clamping plate 3 left and right. The driving device includes a knob 4. An iron plate 5 is fixed to the bottom of the support frame 1, and a magnet 6 for attracting the iron plate 5 is fixed to the lower end of the slide 2.

[0019] like Figure 2 As shown, the lower end of the support frame 1 has multiple left-right extending grooves 1.2. The lower end of the slide table 2 slides in a left-right engagement with the grooves 1.2. A stop block 22 protrudes from the right end of the bottom of the slide table 2 and is used to abut against the inner wall of the groove 1.2. When the stop block 22 abuts against the inner wall of the groove 1.2, the distance between the first clamping plate 1.1 and the second clamping plate 3 is relatively short.

[0020] like Figure 2 As shown, a rotating shaft 7 extending forward and backward is rotatably connected to the lower left end of the slide table 2, and a stop bar 1.3 is located at the lower end of the support frame 1, blocking the rotating shaft 7. Therefore, the right end of the slide table 2 can be lifted, as shown. Figure 3 As shown, when slide 2 moves to the right, rotating shaft 7 also moves to the right.

[0021] The drive device also includes a nut platform 8, a lead screw nut 9, and a lead screw 10. A left-right extending track 23 is provided on the slide table 2. The nut platform 8 is located between the second clamping plate 3 and the baffle 21. The lower end of the nut platform 8 slides left-right with the track 23. The lead screw nut 9 is fixed to the upper end of the nut platform 8. The baffle 21 has an opening for the lead screw 10 to pass through. The lead screw 10 extends left-right through the lead screw nut 9 and engages with it. The left end of the lead screw 10 passes through the second clamping plate 3 and is connected to the second clamping plate 3 by fasteners. The fasteners include a fastening screw (not shown) and a retaining ring 11. The lead screw 10 includes a lead screw body 101 and a short shaft 102 located at the left end of the lead screw body 101. The diameter of the short shaft 102 is smaller than the diameter of the lead screw body 101. The retaining ring 11 is fitted onto the short shaft 102 and rests against the right end of the second clamping plate 3. A fastening screw is screwed onto the left end of the short shaft 102, and the head of the fastening screw rests against the inner wall of the middle part of the second clamping plate 3. The inner diameter of the retaining ring 11 is larger than the diameter of the short shaft 102 but smaller than the diameter of the lead screw body 101. The retaining ring 11 allows the second clamping plate 3 to move to the right along with the lead screw 10 when moving to the right, and the fastening screw allows the second clamping plate 3 to move to the left along with the lead screw 10 when moving to the left. Therefore, this allows the lead screw 10 to be connected to the second clamping plate 3, and the lead screw 10 can also rotate.

[0022] Will Figure 1The right end of slide 2 in the state is raised upwards until... Figure 3 As shown, the stop block 22 is lifted, and then the slide table 2 is pulled to the right a certain distance and lowered. After selecting a suitable position, the block is released, and the magnet 6 will attract the iron plate 5, so the slide table 2 will be positioned.

[0023] exist Figure 1 In this state, the slide 2 can move freely back and forth. When the first clamping plate 1.1 and the second clamping plate 3 clamp onto an object, hold the clamping frame and turn the knob 4. The knob 4 drives the lead screw 10 to rotate. Through the cooperation of the lead screw 10 and the lead screw nut 9, the nut platform 8 moves to the right until the baffle 21 blocks the nut platform 8. At this time, because of the nut platform 8, the second clamping plate 3 cannot move to the right. In this way, the first clamping plate 1.1 and the second clamping plate 3 can be firmly clamped onto the object. (Also see...) Figure 5 At this time, the nut platform 8 is blocked by the baffle 21. Because the second clamping plate 3 of the slide 2 is to move together with the lead screw 10, the lead screw 10 is to move to the right, so the nut platform 8 is also to move to the right. However, since the nut platform 8 is already at the limit position and cannot move to the right, the second clamping plate 3 is also unable to move to the right at this time.

[0024] The clamping frame provided by this utility model has a slide table 2 that can move left and right, allowing adjustment of the distance between the first clamping plate 1.1 and the second clamping plate 3. This allows for a wide range of adjustment of the distance between the first clamping plate 1.1 and the second clamping plate 3, making it convenient to clamp the frame onto objects with a large width. The second clamping plate 3 can also move left and right on the slide table 2, allowing for adjustment of the distance between the first clamping plate 1.1 and the second clamping plate 3. This allows for a small range of adjustment of the distance between the first clamping plate 1.1 and the second clamping plate 3. The driving device can lock the position of the second clamping plate 3 by simply turning the knob 4, making it convenient to use.

[0025] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
