[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figures 1 to 4 As shown, the present embodiment discloses a concrete test block curing box, comprising a curing box body 1 and three test block placing racks arranged in the curing box body 1 at intervals from top to bottom; the concrete test block 3 placing rack comprises a placing rack body 12, an adjusting assembly 2 and a fixing box 13; the placing rack body 12 is slidably connected to the inner wall of the curing box body 1 (it can also be said that the test block placing rack is slidably connected to the inner wall of the curing box body 1), and the fixing box 13 is fixedly connected to the bottom of the placing rack body 12; the adjusting assembly 2 comprises a bidirectional threaded rod 212, a slider 213 and two adjusting rods 215, the two adjusting rods 215 are slidably arranged on the upper surface of the placing rack body 12, a slide groove 214 is arranged on the inner wall of the bottom of the fixing box 13 in a direction perpendicular to the adjusting rod 215, the thread directions of the two ends of the bidirectional threaded rod 212 are opposite, the bidirectional threaded rod 212 passes through the left and right side walls of the fixing box 13 in a direction parallel to the slide groove 214 and is rotatably connected to the left and right side walls of the fixing box 13, and the bidirectional threaded rod 212 The two ends are respectively threadedly connected with the two sliders 213 (specifically, the two sliders 213 are each provided with a threaded hole, one end of the bidirectional threaded rod 212 is passed through the threaded hole of one of the sliders and is threadedly connected with the slider, and the other end is passed through the threaded hole of the other slider and is threadedly connected with the slider), and the top ends of the two sliders 213 are respectively connected with the two adjusting rods 215, and the bottom ends of the two sliders 213 are both slidably arranged in the slide groove 214; thereby, by rotating the threaded rod 212, the slider 213 can be driven to slide along the slide groove 214, thereby realizing the control operation of the sliding of the adjusting rod 215 (and since the threads at the two ends of the bidirectional threaded rod 212 are in opposite directions, when the threaded rod 212 is rotated, the two sliders 213 move in opposite directions, thereby driving the adjusting rod 215 to move in opposite directions), thereby being able to adjust the size of the placement space on the placement frame 12 according to the size of each concrete test block 3 (the width of the concrete test block 3).
[0023] Specifically, the front side of the maintenance box 1 is provided with a door body 11; one end of the bidirectional threaded rod 212 is fixedly connected with a knob 211, and the knob 211 is arranged to fit the outer wall of the fixing box 13, so as not to affect the sliding connection between the placement frame 12 and the maintenance box 1. The bidirectional threaded rod 212 can be easily rotated through the knob 211. A plurality of cross bars 121 are fixedly arranged inside the placement frame 12, and the adjustment rod 215 is slidably connected to the cross bars 121 of the placement frame 12 through a slip ring 216, and the slider 213 is connected to the bottom of the slip ring 216.
[0024] In a preferred embodiment of the present utility model: a plurality of limit grooves 6 are correspondingly provided on the left and right inner walls of the above-mentioned curing box 1, and the left and right outer walls of the above-mentioned placing frame 12 are fixedly connected with limit blocks 5 adapted to the limit grooves 6, and the front side of the placing frame 12 is fixedly connected with a handle 4; during operation, the limit blocks 5 are used to facilitate the convenient removal of the concrete test blocks 3 placed on the placing frame 12 when needed, and the limit blocks 5 can be driven to slide along the inner wall of the limit groove 6 by pulling the handle 4, thereby driving the placing frame 12 to slide out along the inner wall of the curing box 1, thereby realizing the control operation of conveniently taking the concrete test blocks 3.
[0025] Furthermore, the above-mentioned limit blocks 5 are provided with two groups, and the positions of the two groups of limit blocks 5 are distributed symmetrically with respect to the central axis of the placement frame 12 .
[0026] In a preferred embodiment of the present invention: protective plates are provided on the rear side and the left and right sides of the above-mentioned placement frame 12, so that when the placement frame 12 slides out, it is not easy to cause the concrete test block 3 to slide down, which plays a role in protecting the concrete test block 3 and realizes the control operation of conveniently taking the concrete test block 3.
[0027] Working principle: When using the above-mentioned concrete test block 3 curing box, first, when concrete test blocks 3 of different specifications and shapes are placed on the placement frame 12, in order to improve the convenience of adjusting the internal placement space of the placement frame 12, the knob 211 can be rotated through the rotation of the bidirectional threaded rod 212, driving the slider 213 to slide along the inner wall of the slide groove 214, and the slider 213 slides along the inner wall of the slide groove 214, driving the two adjustment rods 215 to slide back and forth along the top wall of the placement frame 12, thereby realizing the control operation of the convenience of adjusting the internal placement space of the placement frame 12.
[0028] Finally, when it is necessary to conveniently take the concrete test block 3 placed on the placement frame 12, the handle 4 can be pulled to drive the limit block 5 to slide along the inner wall of the limit groove 6, thereby driving the placement frame 12 to slide out along the inner wall of the curing box 1, and protective plates are provided on the rear side and left and right sides of the placement frame 12, so that when the placement frame 12 slides out, it is not easy to cause the main body of the concrete test block 3 to slide off, thereby realizing the control operation of conveniently taking out the concrete test block 3.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
