A bidding information display platform for engineering cost estimates

Abstract

This utility model relates to the field of display stand technology, specifically a bidding information display stand for engineering cost estimates. The utility model includes a display stand body, and a statistical component is provided on the inner wall of the display stand body. The statistical component includes a statistical rod slidably connected to the inner wall of the display stand body. By setting up the statistical component, when it is necessary to count the number of times a bidding document has been read by visitors, after a visitor removes the bidding document, the statistical rod moves downwards due to its own weight, causing the receiving end of a photoelectric sensor to move downwards into the mounting slot, thereby receiving the signal light emitted by the transmitting end of the photoelectric sensor, and thus sending an electrical signal to the controller, causing the counter to increment by one. Then the visitor puts it back into the display stand body, and the counter increments again when the next visitor removes it for reading. The same method can be used to count the bidding documents in each compartment of the display stand body, thereby achieving the purpose of counting the number of times bidding documents have been read.

Description

Technical Field

[0001] This utility model relates to the field of display stand technology, and in particular to a bidding information display stand for engineering cost. Background Technology

[0002] The display stand is used to display bidding information for engineering cost estimates. When the display stand is in use, staff can place the bidding documents on the partition of the display stand, so that visitors can pick up the bidding documents and read them.

[0003] The inventors discovered in their daily work that when the display stand was in use, since it simply placed the tender documents on the shelves, the lack of counting the number of times the tender documents were read made it impossible to effectively analyze the visitors' level of interest in the tender documents. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, the display stand simply places the tender documents on the partition, and due to the lack of counting the number of times the tender documents are read, it may not be possible to effectively analyze the degree of visitor interest in the tender documents. Therefore, this utility model proposes a tender information display stand for engineering cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bidding information display stand for engineering cost, comprising a display stand body, a statistical component provided on the inner wall of the display stand body, the statistical component including a statistical rod slidably connected to the inner wall of the display stand body, a photoelectric sensor receiving end installed at the lower end of the statistical rod, an installation groove provided on the inner wall of the display stand body, a photoelectric sensor transmitting end installed on the inner wall of the installation groove, and a counter installed on the inner wall of the display stand body.

[0006] The effect achieved by the above components is as follows: By setting up a statistical component, when it is necessary to count the number of times a tender document has been read by visitors, after a visitor pulls out the tender document, the counting rod moves downwards due to its own weight, causing the photoelectric sensor receiver to move downwards into the mounting slot, thereby receiving the signal light emitted by the photoelectric sensor transmitter, and thus sending an electrical signal to the controller, causing the counter to increment by one. Then the visitor puts it back on the display stand, and the counter increments again when the next visitor pulls it out to read. The same method can be used to count the tender documents in each compartment of the display stand, thereby achieving the purpose of counting the number of times a tender document has been read as much as possible.

[0007] Preferably, a baffle plate is rotatably mounted on the inner wall of the mounting groove, and the baffle plate is located above the photoelectric sensor transmitter.

[0008] The effect achieved by the above components is to minimize the amount of dust entering the mounting slot and affecting the transmitter of the electrical sensor by setting up a shield.

[0009] Preferably, a reset spring is fixedly connected to one end of the shield, and the other end of the reset spring is fixed to the display stand body.

[0010] The effect achieved by the above components is as follows: when the photoelectric sensor receiver moves downward, the baffle is pushed open, which compresses the reset spring; when the photoelectric sensor receiver moves upward, the reset spring resets, which in turn resets the baffle.

[0011] Preferably, a compression spring is fixedly connected to the top of the inner wall of the display stand body, and the other end of the compression spring is fixed to the counting rod.

[0012] The effect achieved by the above components is as follows: by setting a compression spring, after the statistical rod presses against the tender form, the compression spring is in a compressed state, and its reverse force pushes the statistical rod, thereby limiting the tender form.

[0013] Preferably, a limiting rod is fixedly connected to the inner wall of the display stand body, and the statistical rod slides on the limiting rod.

[0014] The effect achieved by the above components is to provide auxiliary limiting for the statistical rod by setting a limiting round rod.

[0015] Preferably, a rubber strip is fixedly connected to the lower end of the statistical rod, and the lower end of the rubber strip is provided with anti-slip stripes.

[0016] The effect achieved by the above components is to increase the friction between the statistical rod and the tender document by setting the rubber strip.

[0017] Preferably, a handle is fixedly connected to the upper end of the statistical rod.

[0018] The effect achieved by the above components is that by setting a handle, pulling the handle upward will cause the statistical lever to be pulled.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting up a statistical component, when it is necessary to count the number of times a tender document has been read by visitors, after a visitor pulls out the tender document, the counting rod moves downwards due to its own weight, causing the photoelectric sensor receiver to move downwards into the mounting slot. This allows the receiver to receive the signal light emitted by the photoelectric sensor transmitter, which then sends an electrical signal to the controller, causing the counter to increment by one. The visitor then puts the document back on the display stand. When the next visitor pulls it out to read, the counter increments again. This same method can be used to count the number of tender documents on each shelf of the display stand, thus maximizing the effectiveness of counting the number of tender document reads. This solves the problem that simply placing tender documents on shelves in the display stand without counting the number of reads may prevent a proper analysis of visitor interest in the tender documents.

[0026] Reference Figure 1 As shown, this utility model provides a technical solution: a bidding information display stand for engineering cost includes a display stand body 1, and a statistical component 2 is provided on the inner wall of the display stand body 1.

[0027] Reference Figure 2 and Figure 3As shown in this embodiment: the statistical component 2 includes a statistical rod 21 slidably connected to the inner wall of the display stand body 1. A photoelectric sensor receiver 22 is installed at the lower end of the statistical rod 21. An installation groove 26 is provided on the inner wall of the display stand body 1. A photoelectric sensor transmitter 23 is installed on the inner wall of the installation groove 26. A counter 210 is installed on the inner wall of the display stand body 1. By setting the statistical component 2, when it is necessary to count the number of times the tender document has been read by visitors, after a visitor takes out the tender document, the statistical rod 21 moves downward due to its own weight, causing the photoelectric sensor receiver 22 to move downward into the installation groove 26, thereby receiving the signal light emitted by the photoelectric sensor transmitter 23, and thus sending an electrical signal to the controller, causing the counter 210 to increment by one. Then the visitor puts it back on the display stand body 1, and when the next visitor takes it out to read, the counter 210 is incremented again. The same method can be used to count the tender documents in each compartment of the display stand body 1. To maximize the effectiveness of counting the number of times the tender documents are read, a baffle plate 24 is rotatably installed on the inner wall of the mounting slot 26. The baffle plate 24 is located above the photoelectric sensor transmitter 23. By setting the baffle plate 24, dust is prevented from entering the mounting slot 26 and affecting the photoelectric sensor transmitter. A reset spring 25 is fixedly connected to one end of the baffle plate 24, and the other end of the reset spring 25 is fixed to the display stand body 1. When the photoelectric sensor receiver 22 moves downward, the baffle plate 24 is pushed open, and the reset spring 25 is compressed. When the photoelectric sensor receiver 22 moves upward, the reset spring 25 is reset, and the baffle plate 24 is reset. A compression spring 28 is fixedly connected to the top of the inner wall of the display stand body 1. The other end of the compression spring 28 is fixed to the counting rod 21. By setting the compression spring 28, when the counting rod 21 presses against the tender document, the compression spring 28 is in a compressed state, and its reverse force pushes the counting rod 21, thus limiting the movement of the tender document.

[0028] Reference Figure 2 As shown in this embodiment: a limiting rod 29 is fixedly connected to the inner wall of the display stand body 1. The statistical rod 21 slides on the limiting rod 29. By setting the limiting rod 29, the statistical rod 21 is assisted in limiting. A rubber strip is fixedly connected to the lower end of the statistical rod 21. The lower end of the rubber strip is provided with anti-slip stripes. By setting the rubber strip, the friction between the statistical rod 21 and the tender form is increased. A handle 27 is fixedly connected to the upper end of the statistical rod 21. By setting the handle 27, pulling the handle 27 upward will pull the statistical rod 21.

[0029] Working principle:

[0030] When the display stand body 1 is in use, staff can place the tender forms on the partition of the display stand body 1, allowing visitors to pick them up and read them. When it's necessary to count the number of tender forms read by visitors, after a visitor removes the tender form, the counting rod 21 descends due to its own weight, causing the photoelectric sensor receiver 22 (e.g., model E3ZG) to descend into the mounting slot 26, thus receiving the signal light emitted by the photoelectric sensor transmitter 23. This sends an electrical signal to the controller, causing the counter 210 (e.g., model JDM11-6H) to increment by one. The visitor then places the form back into the display stand body 1. When the next visitor removes the form to read it, the counter 210 increments again. This same method can be used to count the tender forms on each partition of the display stand body 1. To maximize the effectiveness of counting the number of times the tender document is read, a shield 24 is installed to prevent dust from entering the mounting slot 26 and affecting the transmitting end of the electrical sensor. When the receiving end of the photoelectric sensor 22 moves downward, the shield 24 is pushed open, compressing the reset spring 25. When the receiving end of the photoelectric sensor 22 moves upward, the reset spring 25 resets, causing the shield 24 to reset. A compression spring 28 is installed so that when the counting rod 21 presses against the tender document, the compression spring 28 is in a compressed state, and its reverse force pushes the counting rod 21, thus limiting the tender document. A limiting rod 29 is installed to further limit the counting rod 21. A rubber strip is installed to increase the friction between the counting rod 21 and the tender document. A handle 27 is installed so that pulling the handle 27 upward pulls the counting rod 21.
